`[Detailed explanation about the invention]
`[0001]
`[Technical field to which the invention belongs] This invention is related to an exterior wall panel used when constructing a building, a
`joining structure formed by joining the exterior wall panels, and a joining method of the exterior wall panels.
`[0002]
`[Technical background] In recent years, the construction of buildings has become increasingly industrialized, for example, panel
`construction methods such as constructing a building by constructing panels such as walls, floors, and roofs or the like in advance at a
`factory and assembling these panels at a construction site have been adopted. As a panel used in such kind of panel construction methods,
`for example, a panel as shown in the Fig. 9 is known.
`[0003] Panel 100 shown in the Fig. 9 is a panel obtained in a manner that it has vertical frame members 101 and 101 and horizontal frame
`members 102 and 102 assembled in a rectangular shape, and at the same time, the reinforcing core members 103 ... are assembled vertically
`and horizontally inside the rectangular frame, then a frame body 104 is formed, and a surface member 105 such as a plywood is stuck to
`one surface of the frame body 104. In addition, as described in the invention disclosed in for example, Japanese Unexamined Patent
`Application Publication Official Gazette No. H 7 (1996) - 286383, an outfitting panel in which multiple panels are connected to form a
`large connected panel and a sash frame is assembled in this connected panel is also known. By using this outfitting panel, the work
`efficiency of on-site construction is improved. And, when further installing the furring strips to the aforementioned outfitting panel, a
`waterproof sheet was stapled at four corners of the connected panel, and the furring strips were installed at a predetermined interval from
`the upper side.
`[0004]
`[Problems to be solved by the invention] By the way, in order to realize the versatility of the connected panel which was outfitted, it may
`be desired to outfit only the waterproof sheet without outfitting the furring strips, in this case, if the waterproof sheet was installed to four
`corners of the panel with staples only, there was a problem that air might enter the gap and there is a risk that flapping may occur during
`transportation or rainwater may intrude the space between the panel and the waterproof sheet
`[0005] This invention has been made to solve the above mentioned problems, and the objective of this invention is to provide an exterior
`wall panel which is excellent in waterproofness while eliminating the flapping of a waterproof sheet during transportation, and further to
`provide a joining structure of the exterior wall panels which is excellent in the construction convenience and the waterproofness and a
`method for joining the exterior wall panels.
`[0006]
`[Means for solving the problems] In order to solve the above mentioned problems, the invention described in the Claim 1 has the
`characteristic that for example, as shown in the Figs. 1 ~ 8, in an exterior wall panel 1 (for example, a large-sized wall panel) to be used on
`the occasion of constructing a building is equipped with a panel main body 5 and a waterproof sheet 6 provided in a manner of covering at
`least one surface of the panel main body 5; an adhesive agent S is coated along the peripheries of edge portions 5a, 5b and 5c of at least one
`surface of the aforementioned panel main body 5, and the aforementioned waterproof sheet 6 is stuck from the upper side.
`[0007] According to the invention described in the Claim 1, the adhesive agent S is coated around the edge portions 5a to 5c of at least one
`surface of the exterior wall panel 1, and the waterproof sheet 6 is stuck from the upper side, so when comparing with staple punching, the
`fastening area between the waterproof sheet 6 and the panel main body 5 will increase, and it is possible to prevent flapping of the
`waterproof sheet 6 during transportation of the said exterior wall panel 1. That is, in the case of installing by conventional method of
`punching the staples, the panel main body 5 and the waterproof sheet 6 are adhered at points, but by using the adhesive agent S, the panel
`main body 5 and the waterproof sheet 6 are adhered on the surface, therefore, the fastening area becomes larger and the waterproof sheet 6
`is stably adhered, and it is possible to prevent the waterproof sheet 6 from flapping during transportation of the said exterior wall panel 1.
`[0008] Here, the adhesive agent S does not necessarily need to be coated without interruption around the entire circumference of the edge
`portions 5a to 5c, and may also be coated intermittently.

`The exterior wall panel 1 is a panel used as a roofing material, wall material, etc., and for example, as shown in the Fig. 9, it can be a panel
`obtained in a manner that the vertical frame members 101 and 101 and the horizontal frame members 102 and 102 are assembled in a
`rectangular shape, and a reinforcing core member 103 is assembled vertically and horizontally inside this rectangular frame to form a frame
`body 104, and then the surface member 105 such as a plywood is stuck on one surface of the frame body 104; it is also fine to be merely a
`plate material or the like. In addition, the exterior wall panel 1 may be either a single panel or a large connected panel 1 in which multiple
`panels are connected to become large in size. The waterproof sheet 6 may be of any type as long as it has waterproofness, and it is also fine
`to have both moisture permeability and waterproofness at the same time.
`[0009] The invention described in the Claim 2 has the characteristic that in the exterior wall panel 1 described in the Claim 1, an adhesive
`agent S is continuously coated to at least the upper edge portion 5a of the panel main body 5 from the left end portion 51 to the right end
`portion 52.
`[0010] According to the invention described in the Claim 2, an adhesive agent S is continuously coated to at least the upper edge portion 5a
`of the panel main body 5 from the left end portion 51 to the right end portion 52, so it is possible to prevent water from intruding the inside
`of the waterproof sheet 6 from the upper edge portion 5a, and the waterproofness can be improved. Here, in addition to the upper edge
`portions 5a, the side edge portion 5b and the lower edge portion 5c may also be coated with the adhesive agent S without interruption. It is
`more preferable for the purpose of increasing the waterproofness.
`[0011] The invention described in the Claim 3 has the characteristic that in the exterior wall panel 1 described in the Claim 1 or 2, at least a
`part of the lower edge portion 5c of the panel main body 5 is provided with an uncoated portion 55 to which the adhesive agent S is not
`coated.
`[0012] According to the invention described in the Claim 3, at least a part of the lower edge portion 5c of the panel main body 5 is provided
`with an uncoated portion 55 to which the adhesive agent S is not coated, so in the unlikely event that water intruded the inside of the
`waterproof sheet 6, water can be discharged to the outside from the uncoated portion 55.
`[0013] The invention described in the Claim 4 has the characteristic that in the exterior wall panel 1 described in any of the Claims 1 to 3,
`the waterproof sheet 6 is provided in a manner of protruding a predetermined width to the outside from a lower end portion 54 of the panel
`main body 5.
`[0014] According to the invention described in the Claim 4, the waterproof sheet 6 is provided in a manner of protruding a predetermined
`width to the outside from a lower end portion 54, so in the case when this exterior wall panel 1 is installed at a predetermined place, the
`waterproof sheet 6 protruding from the lower end portion 54 can be made to overlap with the building member where the lower end portion
`54 is installed, and the waterproofness of the joint can be more easily and reliably ensured. In other words, for example, in the case if the
`exterior wall panel is used as an exterior wall panel on the second floor and installed on the girth, by covering and fixing the said joint and
`girth with the waterproof sheet 6 at the protruded lower end portion, it is possible to easily and reliably ensure the waterproofness of the
`joint.
`[0015] The invention described in the Claim 5 has the characteristic that in such a joining structure formed by joining the exterior wall
`panel 1 described in any one of the Claims 1 to 4, the waterproof tapes 13, 25 and 35 are stuck to the joints 11a, 22a, and 32a of an adjacent
`exterior wall panel 1 so as to overlap with both waterproof sheets 6 and 6.
`[0016] According to the invention described in the Claim 5, the waterproof tapes 13, 25 and 35 are stuck to the joints 11a, 22a, and 32a of
`an adjacent exterior wall panel 1 so as to overlap with both waterproof sheets 6 and 6, so the waterproofness of the exterior wall panel 1
`can be easily ensured in the case when it was joined.
`[0017] The invention described in the Claim 6 has the characteristic that in such a joining method for joining the exterior wall panels 1
`described in any one of the Claims 1 to 4, the end portions of the exterior wall panels 1 where the waterproof sheets 6 are stuck are joined,
`next, the waterproof tapes 13, 25, and 35 are stuck to the joints 11a, 22a, and 32a of the exterior wall panels 1 so as to overlap a waterproof
`sheet 6 stuck to both of the aforementioned exterior wall panels 1.
`[0018] According to the invention described in the Claim 6, the end portions of the exterior wall panels 1 where the waterproof sheets 6 are
`stuck are joined, next, the waterproof tapes 13, 25, and 35 are stuck to the joints 11a, 22a, and 32a of the exterior wall panels 1 so as to
`overlap a waterproof sheet 6 stuck to both of the aforementioned exterior wall panels 1, so the waterproofness of the joints 11a, 22a and
`32a can be easily ensured in the case when the exterior wall panel 1 was joined.
`[0019]
`[Preferred embodiments of the invention] Below, the embodiment of the exterior wall panel, the joining structure of the exterior wall
`panels, and the construction method of the exterior wall panels according to this invention will be explained in detail with reference to the
`figures. Fig. 1 is a perspective view showing the state of the large-sized wall panel according to this invention before the waterproof sheet
`was stuck, and Fig. 2 is an exploded perspective view for the purpose of explaining the installation of the sash after sticking the waterproof
`sheet of the same large-sized wall panel.
`[0020] A large-sized wall panel 1 as an exterior wall panel according to this invention shown in the Figs. 1 and 2 can be manufactured in
`advance at a factory or the like. For this large-sized wall panel 1, on the panel main body 5 in a square shape consisting of two side wall
`panels 2 and 2, the dwarf wall panel 3 and the spandrel wall panel 4 joined to the upper side end surface and the lower side end surface of
`these side wall panels 2 and 2, a waterproof sheet 6 is stuck on one surface of the said panel main body 5, and staples 61 are punched into
`four corners. At the central portion of this large-sized wall panel 1, an opening portion 7 is provided. Then, a water stopping plate 8 is
`installed on a lower frame of the inner frame portion 1a which forms this opening portion 7, and further, a sash 9 and a sealing member 10
`for realizing the waterproofness the sash 9 are installed in the inner frame portion 1a.
`[0021] The side wall panels 2 and 2, and the dwarf wall panel 3 and the spandrel wall panel 4 are obtained in a manner that for example,
`same as before, the vertical frame members 2a and 3a and the horizontal frame members 2b and 3b are assembled in a rectangular shape,
`and a reinforcing core member (not shown in the figure) is assembled vertically and horizontally inside this rectangular frame to form a
`frame body, and the surface members 2c, 3c and 4c such as a plywood or the like are stuck on one surface of the frame body.

`(4)
`[0022] For the joining of the aforementioned large-sized wall panel 1, the side wall panels 2 and 2, the dwarf wall panel 3 and the spandrel
`wall panel 4, they can be fixed by fastening with the fastening bolts or screwing the nails, though it is not shown in the figure. The adhesive
`agent S is continuously coated from the left end portion 51 to the right end portion 52 on the upper edge portion 5a of the aforementioned
`panel main body 5. Similarly, the adhesive agent S is continuously coated on the left and right side edge portions 5b of the panel main body
`5 from the upper end portion 53 to a position about 100 mm from the lower end portion 54.
`[0023] Here, about the side edge portion 5b forming the recessed corner, the adhesive agent S is coated at a position about 100 mm to the
`inside from the left end portion 51 or the right end portion 52 of the panel main body (refer to the Fig. 7).
`[0024] In addition, on the lower edge portion 5c of the panel main body 5, the adhesive agent S is coated intermittently from the left end
`portion 51 to the right end portion 52, and an uncoated portion 55 where the adhesive agent S is not coated is formed. At this time, the
`adhesive agent S is coated at a position about 100 mm to the inside from the lower end portion 54 of the panel main body 5. Then, the
`aforementioned waterproof sheet 6 is stuck on the panel main body 5 coated with the adhesive agent S. As the waterproof sheet 6, for
`example, Tyvek (product name: manufactured by DuPont) having waterproofness and moisture permeability or the like can be used.
`[0025] In addition, the waterproof sheet 6 is provided in a manner of protruding a predetermined width to the outside from a lower end
`portion 54 of the panel main body 5. And, during transportation, the adhesive agent of the lower edge portion 5c is in a state of being
`folded to the inside from the coated part and stopped with tape. Here, for the predetermined width, for example, if the said large-sized wall
`panel 1 can be installed on the first floor, the waterproof sheet 6 will be made to protrude about 80 mm to the outside, in addition, if the
`said large-sized wall panel 1 can be installed on the second floor, the waterproof sheet 6 will be made to protrude about 310 mm to the
`outside. The reason why the waterproof sheet 6 of the large-sized wall panel 1 installed on the second floor is long is the purpose of
`forming a portion overlapping with the wall panel on the first floor.
`[0026] In the case when the end portions of the large-sized wall panel 1 and the other wall panel 11 are joined together (flat joint), as
`shown in the Fig. 3, the waterproof sheet 6 on the end portions 51 and 52 on the side of the panel main body 5 is cut at the wood end grain.
`And, as shown in the Fig. 4, the joint 11a of the large-sized wall panel 1 and the other wall panel 11 is fixed by screwing the screw nails 12
`… into the vertical frame member 2a, and at the seam of the joint 11a, a joint tape 13 having waterproofness is stuck so as to overlap with
`both waterproof sheets 6.
`[0027] Next, in the case if the said large-sized wall panel 1 and the other wall panel 21 are joined to form a protruded corner 22 (refer to the
`Fig. 6), as shown in the Fig. 5, the waterproof sheet 6 of the right end portion 52 of the panel main body 5 of the protruded corner joint 22a
`is provided in a way of protruding a predetermined width (for example, 90 mm) to the outside, and the protruded portion is folded back and
`stopped with the tape 23. Then, as shown in the Fig. 6, at the protruded corner joint 22a, the wall panels 21 are fixed to each other by
`screwing the screw nails 24 ... into the vertical frame member 2a, and then the portion of the waterproof sheet 6 stopped with the tape 23 is
`opened, the waterproof sheet 6 is overlapped so as to cover the joint 22a. Further, a joint tape 25 is stuck on the protruded corner joint 22a.
`[0028] Next, in the case when the large-sized wall panel 1 and the other wall panel 31 are joined to form the recessed corner 32 (refer to the
`Fig. 8), as shown in the Fig. 7, the waterproof sheet 6 of the right end portion 52 of the panel main body 5 of the recessed corner joint 32a
`is adhered inside to a predetermined width (for example, 100 mm), and the portion 6a protruding from the adhesive part is folded back and
`stopped with the tape 33. Then, as shown in the Fig. 8, at the recessed corner joint 32a, the panels are fixed by screwing the screw nail 34
`into the vertical frame member 2a, the portion 6a of the waterproof sheet 6 stopped with the tape 33 is opened, and the waterproof sheet 6
`of this opened portion is overlapped on the recessed corner joint 32a. Further, a joint tape 35 is stuck on the recessed corner joint 32a from
`the upper side.
`[0029] Next, the factory outfitting of the above mentioned large-sized wall panel 1 will be explained. First, dwarf wall panel 3 and spandrel
`wall panel 4 are placed on the upper end portion and lower end portion between two side wall panels 2 and 2 that have been separated, and
`their end surfaces are fixed by screwing the nails to form a panel main body 5 in a square shape. Next, the adhesive agent S is coated on the
`edge portion of one surface of the panel main body 5 by a roller (not shown in the figure) or a spray (not shown in the figure) or the like.
`The adhesive agent S will be coated on the upper edge portion 5a and the left and right side edge portions 5b uniformly without
`interruption. The lower edge portion 5c is intermittently coated at a fixed interval (for example, 100 mm), and at this time, it is coated at a
`position 100 mm above the lower end portion 52.
`[0030] Next, a waterproof sheet 6 is stuck on the surface coated with the adhesive agent S, and staples 61 are punched into four corners. In
`this case, as necessary, it is provided in a manner of protruding to the outside from the lower end portion 54 or the side end portions 51 and
`52 of the panel main body 5. Then, the water stopping plate 8 is installed in the lower frame 1b of the inner frame portion 1a of the panel
`main body 5, and further, the sash 9 and the sealing member 10 are installed. In addition, when transporting the large-sized wall panel 1, it
`is in a state that the waterproof sheet 6 of the lower end portion 54 is bent to the inside. By doing so, it is possible to prevent the waterproof
`sheet 6 from being rubbed and broken during transportation. Further, when other members are installed in the lower end portion 54 of the
`large-sized wall panel 1, it is also in a state that the waterproof sheet 6 is folded. By doing so, the work is easy and it is possible to prevent
`the waterproof sheet from being damaged.
`[0031] Subsequently, a method of constructing the above mentioned large-sized wall panel 1 will be explained. In the case of a flat joint
`(refer to the Fig. 4), the screw nails 12… are screwed into the vertical frame member 2a of the joint 11a by screwing from the upper side of
`the waterproof sheet 6, and the joint tape 13 is stuck to the seam of the joint 11a so as to overlap with both waterproof sheets 6.

`(5)
`[0032] In addition, in the case of a protruded corner joint 22a (refer to the Fig. 6), after the portion of the waterproof sheet 6 stopped with
`the tape 23 is opened, the waterproof sheet 6 is brought into contact with another wall panel 21, and the screw nails 24 are screwed into the
`vertical frame member 2a of the protruded corner joint 22a from the upper side and fixed, and a joint tape 25 is stuck to the seam of joint so
`as to overlap with both waterproof sheets 6.
`[0033] Next, in the case of the recessed corner joint 32a, after the portion 6a of the waterproof sheet stopped by the tape 33 is opened, the
`waterproof sheet 6 is overlapped with the waterproof sheet 6 of the other wall panel 31, fixed by screwing the screw nails 34 from the
`upper side of the waterproof sheet 6 into the vertical frame member 2a, and further a joint tape 35 is stuck from the upper side.
`[0034] According to the large-sized wall panel 1 pertaining to this invention described above, the adhesive agent S is continuously coated
`on the upper edge portion 5a of one surface of the panel main body 5 and the left and right side edge portions 5b and 5b, the adhesive agent
`S is intermittently coated on the lower edge portion 5c, and the waterproof sheet 6 is stuck from the upper side, so when comparing with
`staple punching, the fastening area between the waterproof sheet 6 and the panel main body 5 will increase, and it is possible to prevent
`flapping of the waterproof sheet 6 during transportation of the said large-sized wall panel 1. That is, in the case of installing by
`conventional method of punching the staples, the panel main body 5 and the waterproof sheet 6 are adhered at points, but by using the
`adhesive agent S, the panel main body 5 and the waterproof sheet 6 are adhered on the surface, therefore, the fastening area becomes larger
`and the waterproof sheet 6 is stably adhered, and it is possible to prevent the waterproof sheet 6 from flapping during transportation of the
`said large-sized wall panel 1.
`[0035] Furthermore, the adhesive agent S is continuously coated on the upper edge portion 5a, left and right side edge portions 5b and 5b,
`so it is possible to prevent water from intruding the inside of the waterproof sheet 6 from the upper edge portion 5a, and the waterproofness
`can be improved. In addition, the adhesive agent S is intermittently coated from the left end portion 51 to the right end portion 52 on the
`lower edge portion 5c, so in the unlikely event that water intruded the inside of the waterproof sheet 6, water can be discharged to the
`outside from the uncoated portion 55 of the adhesive agent S of the lower edge portion 5c.
`[0036] In addition, the waterproof sheet 6 is provided in a manner of protruding a predetermined width to the outside from a lower end
`portion 54, so in the case when this large-sized wall panel 1 is installed at a predetermined place, the waterproof sheet 6 protruding from
`the lower end portion 54 can be made to overlap with the building member installed on the lower end portion 54, and the waterproofness of
`the joint can be more easily and reliably ensured. In other words, for example, in the case if the large-sized wall panel is used as an exterior
`wall panel on the second floor and installed on the girth (the figure illustration is omitted), by covering and fixing the said joint and girth
`with a waterproof sheet 6 protruding from the lower end portion 54, it is possible to easily and reliably ensure the waterproofness of the
`joint. Furthermore, the waterproof tapes 13, 25, and 35 are stuck on the joints 11a, 22a, and 32a of the large-sized wall panel 1 and other
`wall panels 11, 21, and 31 so as to overlap with both waterproof sheets 6, so in the case when the large-sized wall panel 1 was joined, the
`waterproofness of the joints 11a, 22a, and 32a can be easily ensured.
`[0037] Moreover, in the above mentioned embodiment, a large-sized wall panel in which a sash is assembled is exemplified as the exterior
`wall panel of this invention, however, a single panel may also be used, and similar effects can be obtained not only with a wall panel but
`also with a roof panel or the like. In addition, in this embodiment, the adhesive agent and the staples were used in combination, but it is also
`fine to use the adhesive agent only.
`[0038]
`[Effect of the invention] According to the invention described in the Claim 1, the adhesive agent is coated around the edge portions of at
`least one surface of the exterior wall panel, and the waterproof sheet is stuck from the upper side, so when comparing with staple punching,
`the fastening area between the waterproof sheet and the panel main body will increase, and it is possible to prevent flapping of the
`waterproof sheet during transportation of the said exterior wall panel. That is, in the case of installing by conventional method of punching
`the staples, the panel main body and the waterproof sheet are adhered at points, but by using the adhesive agent, the panel main body and
`the waterproof sheet are adhered on the surface, therefore, the fastening area becomes larger and the waterproof sheet is stably adhered, and
`it is possible to prevent the waterproof sheet from flapping during transportation of the said exterior wall panel.
`[0039] According to the invention described in the Claim 2, an adhesive agent is continuously coated to at least the upper edge portion of
`the panel main body from the left end portion to the right end portion, so it is possible to prevent water from intruding the inside of the
`waterproof sheet from the upper edge portion, and the waterproofness can be improved.
`[0040] According to the invention described in the Claim 3, at least a part of the lower edge portion of the panel main body is provided
`with an uncoated portion to which the adhesive agent is not coated, so in the unlikely event that water intruded the inside of the waterproof
`sheet, water can be discharged to the outside from the part of the lower edge portion where no adhesive is coated.
`[0041] According to the invention described in the Claim 4, the waterproof sheet is provided in a manner of protruding a predetermined
`width to the outside from a lower end portion, so in the case when this exterior wall panel is installed at a predetermined place, the
`waterproof sheet protruding from the lower end portion can be made to overlap with the building member in which the lower end portion is
`installed, and the waterproofness of the joint can be more easily and reliably ensured. In other words, for example, in the case if the exterior
`wall panel is used as an exterior wall panel on the second floor and installed on the girth, by covering and fixing the said joint and girth
`with the waterproof sheet at the protruded lower end portion, it is possible to easily and reliably ensure the waterproofness of the joint.
`[0042] According to the invention described in the Claim 5, the waterproof tapes are stuck to the joints of an adjacent
