Abstract

PROBLEM TO BE SOLVED: To provide a close plate in which a gap between step plates can be easily closed and there is no excessive clearance between the step plates. SOLUTION: The close plate 1 for a step plate is formed from a main body 2, frame materials 3, and reinforcing materials 4. A plurality of circular non-slip patterns are provided on the surface of the main body 2. The frame materials 3 are welded to the rear side of the body 2. Each reinforcing material 4 is welded between the materials 3. The plate 1 is mounted between step plates to close a gap between the step plates with the main body 2. At that time, the frame material 3 is located in an inner space of the gap.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stepping plate spacer, and more particularly to a stepping plate closing plate used for a gap between stepping plates used as a scaffold at a construction site of a building such as a house.

[0002]

2. Description of the Related Art Generally, treads are used as scaffolds at construction sites of buildings. In this case, in order to secure a large scaffolding area, treads may be provided on both sides of the column in parallel. At this time, a gap including the width of the column is formed between the treads. Usually, this gap is closed to ensure safety and improve workability. For this reason, the gap was closed by placing the tread on the gap. The tread placed on the gap is fixed using a wire or the like.

[0003]

However, when the tread is placed on the gap, a step is formed on the scaffold, making it difficult to move. Further, since the tread is used for a purpose different from the intended use of closing the gap between the treads, there is no means for fixing the tread, and the tread is fixed with a wire or the like as described above. For this reason, it takes time to attach and detach the treads, which causes a reduction in workability of scaffold assembly. In addition, the wire and the like become loose while the scaffold is used, causing looseness and the like, which lacks a sense of stability of the scaffold during construction work.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a closing plate for a tread plate which can easily close a gap between the tread plates and has no backlash.

[0005]

According to the first aspect of the present invention, a projection is provided on the lower surface of a flat plate-shaped main body, and the main body is placed between treads arranged side by side at intervals. The gist is that the space between the treads is closed by positioning the protrusion in the space between the treads.

According to a second aspect of the present invention, in the first aspect, the main body and the protrusion are surface-treated by hot-dip galvanizing. According to a third aspect of the present invention, in the first and second aspects, a non-slip pattern is formed on the surface of the main body.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a stepping plate closing plate 1 is composed of a main body 2, a frame member 3 and a reinforcing member 4. The main body 2 is a flat plate formed in a rectangular shape using hot-rolled mild steel (SPHC), and has a plurality of circular anti-slip patterns 5.
Are provided at equal intervals.

The frame material 3 is a rolled steel material for general structure (SS material)
Is formed in the same length as the main body 2 in an L-shaped cross section, and the outer surfaces of the frame member 3 are welded to the upper and lower ends in the longitudinal direction of the back surface of the main body 2 so as to face each other at an interval a. ing.

The plurality of reinforcing members 4 are formed in a rectangular shape using a rolled steel material for general structure (SS material), and are welded at equal intervals between the frame members 3 on the back surface of the main body 2. The main body 2, the frame member 3 and the reinforcing member 4 are subjected to hot-dip galvanizing as a surface treatment for corrosion prevention and rust prevention.

As shown in FIGS. 2 and 3, a cylindrical column 6 is set up according to the length of the tread plate 7. Two handrails 1 for supporting the tread plate 7 at an appropriate height of the support 6
1 is provided. The handrail 11 is supported and fixed by the bracket 8.

At four corners of the tread plate 7, hooks 9 are provided. The tread plate 7 is fixed between the handrails 11 by the hanging portions 9 being hooked on the handrails 11. At this time, the frame member 3 can be inserted into the gap 10 between the treads 7.

As shown in FIG. 3, the step board closing plate 1 is placed between the step boards 7 and the gap 10 is closed by the main body 2. At this time, the frame member 3 is located in the internal space of the gap 10.

In FIGS. 2 and 3, the anti-slip pattern 5 of the main body 2 is omitted. Therefore, according to the present embodiment, since the gap 10 can be closed without making a large step, there is no tripping on the scaffold. In addition, the frame member 3 is located in the internal space of the gap 10, so that the mounted footboard closing plate 1 does not rattle, thereby improving the sense of stability of the scaffold. Furthermore, the mounting of the tread-closing plate 1 is very easy because the tread-closing plate 1 is simply dropped into the gap 10 between the treads 7, and the workability of assembling and dismantling the scaffold can be improved.

The above embodiment may be modified as follows, and the same operation and effect can be obtained in such a case. (1) A handle is provided on the main body 2 for facilitating attachment and detachment of the tread plate closing plate 1.

(2) The circular non-slip pattern is replaced with a non-slip non-slip pattern integrally formed with the main body. As mentioned above, although one embodiment was described, the technical idea other than the claim which can be grasped from one embodiment is described below with those effects.

(A) A handle is provided on the main body 2.
A closing plate for a tread as set forth in claim 1. This makes it easier to attach and detach the tread-closing plate, thereby improving the workability of assembling and dismantling the scaffold.

(2) The step board closing plate according to any one of claims 1 to 3, wherein the reinforcing member 4 is welded between the frame members 3. In this way, the strength of the tread closure plate is increased, safety is improved, and long-term use is possible.

[0019]

According to the first aspect of the present invention, it is possible to easily close the gap between the treads and provide a tread closing plate without rattling.

According to the second aspect of the present invention, it is possible to provide a tread closure plate having excellent corrosion and rust prevention effects. According to the third aspect of the present invention, it is possible to provide a tread plate closing plate excellent in safety.
