Description

[Detailed Description of the Invention] This invention relates to a construction panel used when constructing a wall, a door, etc. of a prefabricated shed.

As this type of construction panel, for example, one described in Japanese Utility Model Application Publication No. 50-115745 has already been proposed.

This panel is formed by framing wood, and has a frame body with dovetail grooves recessed around the entire outer periphery, and a bent edge is raised on all four sides by drawing processing, etc., and the end is attached to the side wall of the dovetail groove. It consists of a surface plate that is bent to form a hook part so as to come into contact with the surface plate, and a packing that fills the space between the bent edges of this surface plate.The surface plate is stiffened by interposing a core body such as plasterboard between the surface plates. This is what we are trying to achieve.

However, in the above-mentioned method, it takes time and effort to form the dovetail grooves on the frame body, and it is difficult to attach the surface plate by contacting the hooks formed around the four circumferences with the side walls of the dovetail grooves. It is difficult in practice, and because consideration is not given to reinforcing the entire panel, it has been used only in areas that require relatively little strength, such as doors, and has the disadvantage of being limited in its range of use.

The present invention has been made in order to eliminate the above drawbacks, and an object of the present invention is to provide a construction panel that is easy to assemble and has sufficient strength to be used as a wall surface, etc.

Examples of this invention will be described below based on the drawings.

FIG. 1 is a perspective view showing a part of the construction panel of this invention in cross section, and the panel 1 of this invention consists of a pair of folded edges 2 that are continuous on the four circumferences by drawing process such as pressing. frame-shaped surface plates 3, 3,
A reinforcing frame 4 framed in a substantially rectangular shape by a channel material having a substantially C-shaped cross section, and an edge bonded to this reinforcing frame 4 and facing to seal between the bent edges 2 of the surface plates 3, 3. The main part is constituted by the closing member 5,
In addition, a roll core 6 is interposed inside the reinforcing frame 4 between the two surface plates 3, 3 by being bonded to the surface plates 3, 3 in the same manner as the reinforcing frame 4. In this case, the surface plate 3, as shown in FIG.
It has a water-resistant structure in which a synthetic resin film 3b such as vinyl chloride is coated on the entire surface of a plate-shaped core material 3a such as a steel plate, and the edge closing member 5 is also formed of a water-resistant material such as synthetic resin. The panel itself has a waterproof structure. As shown in FIG. 3, the edge closing member 5 constituting this panel 1 is fitted between the bent edges 2, 2 of the opposing surface plates 3, 3, and closes the outer wall 4 of the reinforcing frame 4. It is formed into a band shape having a pair of leg pieces 5a, 5a that come into contact with ``, and a covering piece 5b that covers the outer surfaces of both bent edges 2, 2, and a wedge-shaped strip is formed on the outer surface of the leg pieces 5a, 5a. It is fixed by engaging the formed engaging portions 5c, 5c with the edges of the bent edges 2, 2. In addition, the leg pieces 5a,
5a is formed so that its tip abuts against the outer wall 4' of the reinforcing frame 4 when the engaging portions 5c, 5c are engaged, and complements the side wall of the panel 1 to which the edge closing member 5 is attached It's stiff.

Panel 1 of this invention configured as above
is reinforced by reinforcing frames 4 on all four sides and by a roll core 6 in the center, so it has sufficient strength as a construction panel and is relatively lightweight, as shown in Fig. 4, for example. The outer wall 11, the ceiling 12, the floor 13, etc. of a prefabricated shed 10 for outdoor installation can be constructed as shown in FIG. Cross section H as shown in Figure 6
They can be easily connected using a shaped connecting member 14 or a corner connecting member 15 having panel mounting grooves 15', 15' in the right angle direction. In addition, in FIG. 4, 16 is a skylight, 17 is a window provided on the outside 11, 18 is a foundation, and 19 is an overhang for access.

Moreover, the panel 1 of this invention is shown in FIGS. 7 and 8.
It can also be used for the door section 21 of the bathroom 20 as shown in the figure, in which case one attachment piece 21a is fixed to the door frame 22, and the other attachment piece 21b of the hinge 21c is fixed to the door frame 22. As shown in
The panel 1 of this invention is fixed to the panel 1 with a screw 23 that passes through the edge closing member 5, the bent edge 2, and is screwed to the reinforcing frame 4 and the mounting seat 24 that abuts the reinforcing frame 4. The door portion 21 formed by the door portion 21 is made openable and closable. In addition, 25 is a handle attached to the door part 21, 26 is a bathtub, 27 is a toilet bowl,
28 is a wash basin.

As explained above, according to the construction panel of this invention, the top plate, which is bonded to the front and back surfaces of the reinforcing frame facing each other, is formed into a picture frame shape by raising continuous folded edges around the four circumferences. This prevents water from leaking from the corner portions of the surface plate, and an edge closing member is installed between the bent edges of these surface plates, and the legs of this edge closing member are brought into contact with the outer wall of the reinforcing frame. By using the tip of the leg piece as a water cutter, water is prevented from entering into the reinforcing frame, so it has a high waterproof function as a whole and is suitable for prefabricated buildings for outdoor installation, bathrooms, etc. It can be used in areas where water resistance is required, such as door sections or partitions. In addition, since the inside of the panel is equipped with a reinforcing frame and a roll core, it is possible to obtain high strength as a whole, and the tips of the leg pieces of the edge closing member are in contact with the outer wall of the reinforcing frame. This makes it possible to improve the rigidity from the side.

Moreover, since there is no distinction between the front and back, there is no need to determine the surface position during installation work, and it has excellent effects such as easy assembly, and its utility value is remarkable.
