DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a temporary enclosure panel according to the present invention. The temporary enclosure panel 1 generally includes a panel main body 2 and a plurality of connecting members 6 provided at a rear portion of the panel main body 2.

The panel body 2 is formed by bending a vertically long thin metal plate such as iron or stainless steel along a plurality of fold curves extending in the longitudinal direction, and joining the joining portions 3 and 4 to both end portions extending in the longitudinal direction. Reinforcing portions 5,5 are formed between the portions 3,4.

The joints 3 and 4 and the reinforcement 5 are shown in FIG.
One of the joints 3 of the joints 3 and 4 is located at a predetermined distance from one end of the panel body 2.
A joint surface 34 that is bent along the folding curves (bent portions) 31, 32, and 33 of the book and extends from the panel main body 2 at a substantially right angle with an outer angle of about 270 degrees, and an oblique angle with the joint surface 34 and an outer angle of about 135 degrees The joining surface 35 extends outward and the reinforcing surface 36 extends substantially parallel to the panel body 2 at an outer angle of about 315 degrees with the joining surface 35. The joining surface 35 and the reinforcing surface 36 adjacent thereto are formed. Side projection 3
7 are formed.

The other joint portion 4 is bent along three fold curves 41, 42, 43 spaced apart from one end of the panel main body 2 by a predetermined distance, and is substantially perpendicular to the panel main body 2 with an outer angle of about 270 degrees. An extending joining surface 44 and the joining surface 44
And joining surface 4 extending diagonally inward with an outer angle of about 225 degrees
5 and a reinforcing surface 46 extending substantially parallel to the panel main body 2 with an outer angle of about 225 degrees, and the connecting surface 45 and the reinforcing surface 46 adjacent thereto are formed with an engaging recess 47. Are formed. In addition, both joints 3, 4
The lengths of the joining surfaces 34 and 44 and the joining surfaces 35 and 45 are equal. Therefore, in a state where the joints 3 and 4 of the adjacent temporary enclosure panels 1 arranged in parallel are engaged with each other, the side projection 37 and the engagement concave portion 47 are engaged without any gap and the adjacent temporary enclosure panels 1 are engaged. Form a continuous flat surface.

Each of the reinforcing portions 5, 5 has four bending curves (bending portions) 51, 52, 5 extending in the longitudinal direction of the panel body 2.
Fold along 3 and 54, two outside bent portions 5
1 and 54 are in contact with each other to form an equilateral triangle or a hollow triangular prism having an isosceles triangular cross section as shown in the figure. The panel body 2 is connected, and the front surface of the panel body 2 is flat. The contact portion 55 may be welded from the outside (the front side of the panel main body) if the front surface of the panel main body 2 is formed flat, or the bent portion 5 may be formed based on the rigidity of the panel main body 2.
No welding is necessary in a state where the first and the first abutments are in contact with each other. It is preferable that the height of the reinforcing portions 5 and 5, that is, the amount of protrusion toward the rear, is such that the bottom 56 of the hollow triangular prism is located on a line connecting the reinforcing surfaces 36 and 46, and the hypotenuses 57 and 57
Is determined.

The sectional shape of the reinforcing portions 5, 5 may be as shown in FIG. In the reinforcing portions 5 and 5 shown in this figure, the width of the contact portion 55 'is increased so as to make surface contact, and the rivet 58, bolts and nuts, screws, other mechanical connecting means, or welding are integrated. Are connected together. However,
If the contact portion 55 'can be held without a gap based on the rigidity of the panel main body 2, the above-described connecting means and the like are unnecessary.

The connecting member 6 is made of flat steel made of the same metal material as the panel body 2 and has a through hole 61 for attaching a hook bolt in the center. As shown in FIG. , 4 and the reinforcing parts 5, 5 are fixed to the upper and lower three stages, respectively. The fixing method is preferably welding, but mechanical connection means such as bolts and nuts, screws, and rivets may be used. The connecting member 6 may extend over the joints 3 and 4 on both sides beyond the reinforcements 5 and 5 or may extend between the reinforcements 5 and 5. The shape can be freely changed. In addition, the connecting member 6 does not need to be made of the same material as the panel main body 2, and in this case, the connecting member 6 is fixed to a joint or the like by mechanical connecting means.

In the temporary enclosure panel 1 having the above configuration, as shown in FIG. 4, hook bolts 7 are fixed to the through holes 61 of the respective connecting members 6, and the hook bolts 7 are constructed around the construction site. The supporting members 18 of the supporting structure 18 are continuously leaned against the connecting members 19, and the joints 3, 4 on both sides are joined to the joints 4 ', 4'
3 ''. Therefore, the front surface of the temporary enclosure 20 composed of the temporary enclosure panels 1, 1 ', 1''and the like has no irregularities, is completely flat, and has no projection of the hook bolt 7. Further, since the joints 3 and 4 at both ends of the temporary enclosure panel 1 are engaged with the joints 4 'and 3''of the adjacent temporary enclosure panels 1' and 1 '', the construction site cannot be seen through the gap. .

The means for attaching the temporary enclosure panel 1 to the support structure 18 is not limited to a hook bolt, and a U bolt 8 may be used as shown in FIG. It may be connected to the material 19 or a simple hook 9 shown in FIG. 7 may be used. The hook 9 is formed by bending one end in the longitudinal direction of a flat steel having a predetermined length into a U-shape along the outer peripheral shape of the horizontal member 19 to form an engaging portion 91, and folding the other end in the opposite direction. A substantially S-shaped member having another engaging portion 92 formed thereon, and the engaging portion 93 has a protrusion 94 protruding from the outside toward the inside. And
The hook 9 engages the engaging portion 92 with the connecting member 6 from below, and the projection 94 engages with the through hole 61 and is fixed. The other engaging portion 91 is engaged with the horizontal member 19. Thereby, the temporary enclosure panel 1 is supported by the support structure 18.

In the above description, the panel body 2 is formed by bending a metal plate material. However, the panel body 2 is formed by extrusion molding using a metal material or a synthetic resin material, or by injection molding using a synthetic resin material. They may be formed integrally. In the case of extrusion molding or injection molding in this manner, the strength can be increased by making the thickness of the joining portions 3 and 4 and the reinforcing portion 5 larger than the thickness of the panel body 2. In addition, when the metal plate material is bent, the contact portion 5 in the reinforcing portion 5 is formed.
Although a vertical streak remains in 5, extrusion molding or injection molding has an advantage that the front surface of the panel main body 2 can be completely flat.

The shapes of the joints 3 and 4 and the reinforcing portion 5 are not limited to those in the above embodiment, and the joints 3 and 4 have the same shape when the temporary enclosure panels 1 having the same shape are arranged side by side. Any shape may be used as long as it engages with the other joints 3 and 4 provided on the panel 1, the shape of the reinforcing portion 5 may be rectangular, or a rib rising from the panel body 2 may be used. When the panel body 2 is manufactured by injection molding, in addition to the reinforcing portion extending in the vertical direction, or instead of the reinforcing portion in the vertical direction, a reinforcing portion extending in an oblique direction or a horizontal direction may be provided as appropriate.

Further, when the panel main body 2 is injection molded, the connecting member 6 made of a metal plate may be embedded in the panel main body 2, the joints 3, 4, or the connecting part 5 and integrally molded. Furthermore, the connecting member 6 is not always necessary, and a hole for attaching the hook 9 shown in FIG. 7 may be provided in the joints 3, 4 or the reinforcing portion 5, and the hook 9 may be hooked on this hole.

[0019]
