BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back surface reinforcing device in a wall panel device which is provided along a structural wall surface to form a decorative wall, and more particularly, to a pillar for mounting the panel and an intermediate pillar for supporting the back surface of the panel. The present invention relates to a back reinforcing device in a wall panel device for fixing a wall to a wall.

2. Description of the Related Art Conventionally, a plurality of columns are erected at predetermined intervals between a ceiling rail and a ground rail fixed to a ceiling and a floor along a wall surface, and an intermediate column is erected appropriately between the columns. Then, in a wall surface panel device in which a panel is mounted between the surfaces of adjacent columns, one piece of the L metal fitting is fixed to the wall surface and the other piece is connected to the other piece in order to increase the supporting strength in the normal direction of the panel. There is provided a structure in which the long holes formed in the column are used to connect the side walls of the column or the intermediate column with the wall while adjusting the distance between the wall and the column.

However, when the above-mentioned L metal fitting is used,
Since it is necessary to previously provide screw holes on the side surfaces of the support pillar and the intermediate support pillar, the number of man-hours for processing the support pillar and the intermediate support pillar is increased, and the mounting position of the L metal fitting is not limited. The degree of freedom is determined by the length of the long hole limited by the dimension of the L metal fitting in the depth direction.

Therefore, the present applicant has filed Japanese Patent Application Laid-Open No. 9-4174.
As disclosed in Japanese Patent Publication, a pressing member for pressing and moving the support post from the wall surface side is provided so that the pressing position with respect to the support post can be changed in the front-back direction, and the pressing member abuts against the back surface of the support post. A plate portion, a screw shaft that is screwed into a screw portion formed on the contact plate portion from the rear, and a rotary operation unit that is integrally connected to the rear end of the screw shaft and that rotates the screw shaft. In addition, the left and right width of the operating part is configured to be larger than the left and right width of the support, the support is configured as an annular body with a recess into which the screw shaft can be inserted, and the contact plate is fitted into the recess of the support. A structure is provided in which a fitting portion for holding is formed.

However, in the structure described in the above-mentioned publication, it is necessary to use a column having a special shape in which a recess for receiving the screw shaft is formed on the back surface, which is not versatile. For example, to partition the indoor space, the front and back surfaces are separated. It is impossible to use the above-mentioned pillars in a wall panel device having a panel, and it has not been adopted as an intermediate pillar that is appropriately erected between the pillars in view of cost. Further, in the structure described in the above-mentioned publication, only the space between the back surface of the column and the wall surface is stretched so that the panel is not deformed toward the wall surface side, and it is impossible to prevent the panel from being deformed toward the front side.

[0006]

Then, the neck portion 14A of the holding portion 14 of the pillar 3 is received in the opening portion 53 of the ceiling connector 12, and the pillar portion 1 is formed by the substrate 52 and the both restricting plates 57, 57.
3 so as to wrap around 3 and to form the triangular dowel 5
8 and 58 are loosely fitted and mounted in the vertically long holes 60 and 60 on both side surfaces of the column portion 13. In this state, the support pillar 3 is erected between the top rail 1 and the ground rail 2 as described above, and then, as described above, the engaging edges 17, 17 of the panel 5 are held by the holding portions 14, 14 of the support pillars 3, 3. To the panel 5 with the panel receiver 10.
Support the bottom of the. Finally, the triangular dowel 58 is finally pushed down the ceiling connecting member 9 in a state where it is temporarily held in the vertically long hole 60 so that both downward engaging claws 55, 55 are engaged holes 59, 59 in the adjacent panels 5, 5. At the same time as the upper edge plate 16 of the panel 5 is pressed by the pressing plate 54, the triangular dowels 58, 58 engage with the corresponding mounting holes 61, 61 in a detented state. At this time, the holding pieces 56, 56
Are located in the notches 19 of the corresponding panel 5, respectively, and stop the edges of the upper edge plate 16 where the notches 19 are formed, so that the notches 19 are formed. The inward deformation of the edge portion is suppressed by the strength reduction of both upper side portions.

When the ceiling connector 12 is mounted at a predetermined position, the upper portion of the board 52 is engaged with the slit 27 formed in the neck portion 14A of the support column 3 and the opening 53 is formed.
Since the neck portion 14A below the slit 27 is received and held therein, and since both the regulation plates 57, 57 are joined to both side surfaces of the column portion 13, the top connector 12 can be moved forward, backward, leftward and rightward with respect to the column 3. It does not move, and on top of that, the triangular dowel 58
Since it engages with the mounting hole 61 in a detented state, it does not move upward. Therefore, the panel 5 with the downward engaging claws 55 of the ceiling connector 12 inserted in the engaging holes 59 can move to the front, rear, left and right. The movement is restricted and the upward movement is also restricted. Furthermore, the two panels 5 and 5 that are adjacent to each other via the column 3
The top connecting tool 12 connects the parts to each other.

In the back reinforcing device 6 according to the present invention, the pillar 3 or the intermediate pillar 4 having the above-described shape is fixed to the wall surface W by the same supporting metal fitting 7 and the fixing metal fitting 8, and the panel 5 is deformed in the normal direction. However, when it is used only for fixing the column 3, the above-mentioned second engaging pieces 33, 33 are not always necessary, and only the engaging claws 33A, 33A are provided. May be. Further, the support metal 7 is
Although the support plate portion 31 is provided on the fitting plate portion 30 so as to project laterally, the inverted T-shape when viewed from the front is shown, but it may be L-shaped when viewed from the front or cross-shaped when viewed from the front. The position of the screw hole 34 provided in the support plate portion 31 is such that when the support fitting 7 is attached to the support pillar 3 or the intermediate support pillar 4, the screw shaft 37 of the fixing fitting 8 is located on the side surface of the support pillar 3 or the intermediate support pillar 4. It is preferable to set them as close to each other as possible to enhance the supporting strength.

The back reinforcing device in the wall surface panel device according to the present invention as described above has a symmetrical front and back surface which can be used both when the partition wall is formed in the interior space and when the decorative wall is formed along the wall surface. By using a double-sided panel mounting type column, you can mount the panel on the holding part on the front side of the column and use the holding part on the back side to easily and firmly attach the support metal fittings only by rotary fitting and bending work. Also, by adjusting the screwing amount of the screw shaft of the fixing bracket to the screw hole of the support bracket according to the distance between the wall surface and the pillar, and attaching the fixing plate of the fixing bracket to the wall surface, the pillar is connected to the wall surface It is possible to perform reliable reinforcement in the left-right direction. Furthermore, in the case where an opening groove is formed in the center of the back surface between the support columns and an intermediate support pillar having rims on both sides of the opening groove is erected, the opening groove and both rims of the intermediate support pillar are utilized. It is possible to easily and firmly attach the support fitting to the intermediate column by turning the support fitting upside down and performing the same rotary fitting and bending work as described above.
