[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold used for a passage or a work floor of a scaffold at a construction site.

[0002]

2. Description of the Related Art As this type of scaffolding plate, as shown in FIG. 6, a front plate 62 integrally formed with a parallel hanging reinforcing plate 61, and a back plate 63 joined to the lower end of the reinforcing plate 61 by welding. The front plate 62 is known to have a large number of non-slip holes 64 formed by pressing before the front plate 62 and the back plate 63 are welded.

[0003]

The manufacturing process of the scaffold requires a welding process, which makes mass production difficult and expensive. Also, the hole 64 drilling by pressing is another factor of high cost because the top plate 62 has a complicated shape.

[0004] An object of the present invention is to provide a scaffold for a construction site which solves the above-mentioned problems.

[0005]

[Function] In the scaffold for a construction site according to the present invention, the core
The material is cross-section eccentric square shape by aluminum extrusion mold material
The top wall, both side walls and
And a bottom wall.
Located on the top of the wall, directly above each side wall and partition wall
Ridges are provided, and grooves face the opposing surfaces of adjacent ridges.
It is formed to make a pair in close contact.
Since both edges of the skin material are freely inserted and removed, a welding process is unnecessary in the manufacturing process of the scaffold plate. Moreover, the partition

You.

Further, since a large number of holes are formed in the skin material so as to be scattered, and an upwardly projecting annular projection for preventing slippage is provided at an edge of the hole, drilling and processing of the projection are easy. I can do it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

Referring to FIG. 1 and FIG. 2, the scaffold plate comprises:
It is composed of one core material 11 and four skin materials 12.

The core member 21 is formed in an uneven square shape by an aluminum extrusion member of JIS A6N01S-T5, and has a top wall 21, both side walls 22 and a bottom wall 23, and three parallel vertical reinforcing partition walls 24. Consisting of An inverted L-shaped ridge 25 and a partition located on the upper surface of the top wall 21 and directly above the side walls 22
A T-shaped ridge 26 is formed just above 24 . This
These ridges 25 and 26 should be
Grooves 27 extending over the entire length of the
It is formed as follows.

[0011] skin material 12, which has been formed in a strip of aluminum sheet of JISA5052, adjacent engagement
The length is large enough to fit into the ridges 25 and 26 ,
It has a width and a thickness. A number of holes 31 are formed in the skin material 12 in two rows in the length direction. The edge of the hole 31 is provided with an upwardly projecting annular projection 32 for preventing slippage by subjecting the hole 31 to burring.

Both edges of the skin material 12 are transferred to a pair of grooves 27.
It is movably inserted. In the state where the skin material 12 is inserted into the groove 27 , required portions of the ridges 25 and 26 are caulked, whereby the movement of the skin material 12 is restricted.

FIG. 3 shows a modified example of the core material. In this modification, adjacent ridges 25, 26 on the top surface of the top wall 21 are provided.
A tall ridge 41 is formed at the center in the width direction between ,
Short protrusions 42 are respectively formed on both sides of this. Then, both edges of the skin material 12 are the tall ridges 41 and the short ridges.
At the top of 42, the entire skin material 12 is inserted into the groove 27 in a state of being curved in a cross-sectional arch shape.

FIG. 4 shows another modification of the core material. The core material 11 according to the other modification has a top wall 43 that is curved in an arch shape in cross section. Skin material 12 is the top wall
Its edges are inserted in a state of being curved I 43 Niso
Have been.

3 and 4, the upper end of the upper surface of the skin material 12 protrudes upward from the upper end surfaces of the ridges 25 and 26.
Thereby, the function of the anti-slip is effectively exhibited. Ma
In addition, the skin material 12 is easily inserted into the grooves 27 and 44, and the skin material 12 is hard to rattle.

FIG. 5 shows a modification of the skin material.
In this modification, a raised portion 52 is provided at the center in the width direction of the skin material 51.
Are formed. The top surface of the raised portion 52 is formed slightly higher than the upper end surfaces of the ridges 25 and 26.

In the above, only the upper surface of the core, but the grooves are formed, also to form a groove on the lower surface of the core material, in which,
A skin material may be inserted.

Further, the skin material may be formed of a synthetic resin such as stainless steel or polyethylene instead of aluminum.

[0019]

According to the present invention, since a scaffold plate manufacturing process does not require a welding process and drilling and non-slip projections can be easily processed, mass production of the scaffold plate is easy and manufacturing costs are reduced. .

Moreover, when the core material is reinforced by the partition walls,
In both cases, the skin material straddles both side walls or partition walls
The strength of the scaffold is guaranteed
Is done.
