This is solved by a wall body in which an operation hole is formed to enable operation of the operation portion of the screw structure from the outside .

In the wall body, the mounting screw assembly may be configured to comprises an adhesive injection hole from the distal end surface of the frame fixing male screw member formed therethrough toward the proximal end face.

Moreover, it is good also as a structure where the frame for a curvature prevention which suppresses the curvature deformation | transformation to the out- of- plane of the said board | plate material is fixed to the wall surface of the said existing wall body located between the said adjacent board | plate material support frames.

According to the invention of claim 1, since the plate material is inserted and supported between the adjacent plate material supporting frames fixed to the wall surface of the existing wall body, the wall body is used by using the wall surface of the existing wall body as it is. It can be easily constructed, and further, since the plate support frame is distanced from the wall by the mounting screw structure, there is an air layer of a certain thickness between the plate and the wall. As a result, the heat insulation can be effectively exhibited. Further, the operating member formed integrally with the internal thread body for adjusting the frame verticality is rotated with respect to the external thread body for fixing the frame via the operating hole formed in the projecting piece portion of the supporting frame for the plate material, An interval between the support frame and the wall surface can be adjusted, and thereby an accurate vertical degree can be given to the plate material in the assembled state.

According to the invention of claim 2, the frame fixing male screw body can be fixed to the wall surface of the existing wall body by the adhesive injected from the adhesive injection hole penetrating the frame fixing male screw body .

  The plate structure supporting main frame 2 (2A, 2B, 2C) and the plate material warpage preventing main frame 3 (3A, 3B) are arranged at predetermined positions as shown in FIG. And fixed to the wall surface Ta. Specifically, as shown in FIG. 5, in the state where the frame fixing male screw body 41 in the mounting screw structure 4 is screwed and inserted into the female screw body 43, the adhesive is injected from the adhesive injection hole 42 of the male screw body 41. 50 is injected into the wall surface Ta of the wall body T, and the base portion 41b of the male screw body 41 for fixing the frame is bonded to the wall surface Ta. The adhesive injection operation may be performed through the operation holes 25 of the projecting pieces 23 of the plate material supporting main frame 2 (2A, 2B, 2C) and the plate material warpage preventing main frame 3 (3A, 3B).

  In this state, the verticality of the plate material supporting main frame 2 (2A, 2B, 2C) and the plate material warpage preventing main frame 3 (3A, 3B) is adjusted. That is, the base end side of the weight suspension member M is inserted into the support holes 26 (36) on the upper end side of the main frame 2 (2A, 2B, 2C) for plate material support and the main frame 3 (3A, 3B) for plate warpage prevention. On the other hand, the base end side of the confirmation member N is inserted into the support holes 27 (37) on the upper end side of the main frame 2 (2A, 2B, 2C) for supporting the plate material and the main frame 3 (3A, 3B) for preventing warpage of the plate material. Check the position of the weight V.

  If the plate material supporting main frame 2 (2A, 2B, 2C) and the plate material warpage preventing main frame 3 (3A, 3B) are inclined in the front-rear direction, a rotation operation tool such as a wrench (not shown). Is inserted into the operation hole 25 of the projecting piece 23 and used to operate the operation portion 45 of the mounting screw assembly 4 to rotate and shift the male screw body 41 for fixing the frame. By rotating the frame fixing male screw body 41, the distance between the plate material supporting main frame 2 (2A, 2B, 2C) and the plate material warpage preventing main frame 3 (3A, 3B) and the wall surface Ta is adjusted. Then, the plate material supporting main frame 2 (2A, 2B, 2C) and the plate material warpage preventing main frame 3 (3A, 3B) can be set vertically.

  When the plate material supporting main frame 2 (2A, 2B, 2C) and the plate material warpage preventing main frame 3 (3A, 3B) are set vertically, the predetermined number of plate materials 1 are adjacent to each other as shown in FIG. The plate frames are supported by being dropped from above between the main frames 2A and 2C for supporting plate members and between 2C and 2B.

  In this case, the groove 11 in the plate material supporting main frame 2 (2A, 2B, 2C) is fitted into the projecting piece portions 23, 23 of the plate material supporting main frame 2 (2A, 2B, 2C), while preventing the plate material from warping. The plate 1 can be easily supported between the adjacent plate support main frames 2A and 2C and between 2C and 2B simply by being fitted into the projecting piece 33 of the main frame 3 (3A, 3B). The plate material 1 in this state is prevented from warping and deforming out of the construction surface by the action of the plate material warpage preventing main frame 3.

  Thereafter, the gap existing on the left side of the group of plate members 1 in the left row is pushed in from the front by the long adjustment plate 5A for concealing the left side gap to conceal the gap, and exists on the right side of the group of plate members 1 in the right column The gap to be hidden is concealed by pushing the long adjustment plate 5B for concealing the left gap from the front. These adjustment plates 5A and 5B may be fixed with an adhesive or the like.

  Next, it is impossible to drop the uppermost plate member 1X of the left and right rows of plate members 1X from above as in the case of the previous plate member 1 group because the ceiling P is in the way. Therefore, the uppermost plate member 1X is already attached as shown in FIG. 10 with the plate member supporting subframes 2D, 2E, 2F and the plate member warp prevention subframes 3C, 3D being assembled. If the adhesive 50 is injected from the adhesive injection hole 42 in the mounting screw structure 4 in this state, the adhesive is fixed to the wall surface Ta of the wall T.

  As shown in FIG. 7, the uppermost plate member 1X is formed with a through hole 13 corresponding to the mounting screw assembly 4, so that the adhesive 50 can be injected for positioning and tilt adjustment before and after. The operation of the operation portion 45 of the mounting screw assembly 4 is performed using the through holes 13. In addition, what is necessary is just to block | close the through-hole 13 currently formed in the said board | plate material 1X with the plug 60 shown in FIG.

  When the fixing of the uppermost plate member 1X to the wall surface Ta is completed, the left and right gaps of the plate member 1X are pushed in from the front by the adjustment plates 6A and 6B, respectively. Finally, the upper gap adjusting plates 7A and 7B are pushed in from the front to conceal the gap between the plate material X and the ceiling P.

  Thus, since the plate material 1 is inserted and supported by the plate material supporting main frames 2A, 2B, 2C and the plate material supporting subframes 2D, 2E, 2F fixed to the wall surface Ta, the existing wall body T is used as it is. Thus, the wall body S can be easily constructed, and further, a certain distance exists between the plate material supporting sub-frames 2D, 2E, 2F and the wall surface Ta of the wall body T. A sealed air layer W having a certain thickness exists between the two and the heat insulating property can be improved. Moreover, if a paulownia material is used as the board | plate material 1 like this example, a humidity control effect will be improved further.

  In addition, the plate material supporting main frames 2A, 2B, 2C and the plate material warpage preventing main frames 3A, 3B are fixed to the wall surface Ta via a specific mounting screw assembly 4. The vertical wall body S which is not influenced by the front-back inclination can be easily obtained.

  In the above embodiment, a plurality of plate material supporting frames 2 are arranged at regular intervals in the left-right direction and the plate materials 1 are arranged in parallel in the vertical direction. It is also possible to arrange the frames 1 in the left-right direction by arranging the frames 2 in the up-down direction at regular intervals.
