Embodiment

Below, describe in detail specific embodiment of the present invention according to drawing.Fig. 1, Fig. 2 represent an example of the framework relevant with the present invention, and Fig. 1 is that oblique view, Fig. 2 are the A-A line section of Fig. 1 and the B portion enlarged drawing of section thereof.Framework is provided with door 1 in front, at left and right side assembling side wallboard 2, assembles rear side wallboard 3 overleaf, and framework is closed.

Side wallboard 2 and rear side wallboard 3 form at the Wall board 4,5 that connects 3 same shapes up and down respectively.Each Wall board 4,5 by molding synthetic resins such as polyacrylics, forms the tabular of essentially rectangular, has smooth front, at top left and right end portions branch, is provided for tying and is fixed on known touching by formula tying device 7 on the chassis body.

And, side Wall board 4 and rear side Wall board 5, because be consistent with the chassis body shape, the same structure that width is different, so the Wall board 4 of following explanation side, the explanation of rear side Wall board 5 is omitted.

Side Wall board 4 (the following Wall board that simply is called) has the flat bottom surface 8 with the regulation depth of panel front 4a approximate vertical as shown in Figure 2 in the bottom, be provided with between this bottom surface 8 and front 4a and form stair-stepping 2 grades end difference 9.In addition,, in this end difference, have, be set to through about whole Wall board to smooth side plate 11 near the depth near the 9a position, the 2nd grade of front of bottom surface 8 on top.And then, the 12nd, strengthen the reinforcement on Wall board 4 tops.

Attachment between the Wall board 4 that forms like this, be configured to as shown in Figure 2 on the 2nd grade of front 9a of end difference 9 of Wall board 4 of the side above being disposed at, dispose below the configuration Wall board 4 side plate 11 and constitute, bottom surface 8 and the 2nd grade of end difference are configured in Wall board back, below, overlapping portion is set.

If the installation steps of actual wall panel are described, then be to install in proper order from 4 beginnings of below Wall board.The back of the side plate 11 of Wall board 4 forms the slit below mounted, and the bottom surface 8 that will be installed in the Wall board 4 between this slit is inserted and connect.Insertion operates under the state that the end difference of the first floor is inserted into, because middle end difference tying is on the side plate 11 of lower wall panel 4, thus can further not insert, under this state, by the tying device 7 of tying operation upper part on chassis body, assembly wall panel 4.

And then, on the foot of chassis body wallboard installation position, form the groove at the regulation position of inserting Wall board bottom, on topmost portion, form the recess of the depth consistent with the side plate shape of Wall board.

Like this, promptly use the polylith Wall board to form wallboard, by attachment is made as embedded structure intersection is set, also be difficult to produce the slit between Wall board, framework inside is difficult for falling into dust.In addition,, can reduce every Wall board, can make by resin forming easily, can seek the lightweight of whole wallboard because of forming wallboard by connecting the polylith Wall board.
