DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for easily closing a scaffold opening.

[0001]

2. Description of the Related Art Conventionally, in a scaffolding group required for construction work or construction for another purpose, it is necessary to take measures for safety of an opening formed at a joint thereof, that is, how to close the opening in a safe state. It was requested on site that they could do it.

Heretofore, in the related art, a veneer plate or the like having a substantially rectangular shape is installed in the opening formed in the joint portion of the scaffolding assembly so as to close the opening between the scaffolds.

[0003]

However, in the conventional measures of this kind, a relatively thick plywood must be used in order to maintain a predetermined strength, so that a step is formed on the scaffold. There was a problem that a worker's feet became extremely dangerous.

[0004] Furthermore, since the frame material and the veneer are made of different materials, a problem has also arisen when fixing them with a number line.

[0005] In some workplaces, there is a case in which no countermeasures are taken because it takes much time without closing the openings between the scaffolds with a plywood or the like, and the openings of the scaffolds are sometimes left as they are.

[0006] Thus, the present invention has been devised in order to address such a conventional problem, and is easy to install, the installation cost is lower than in the past, and there are almost no steps, so the foot is safe. It is still another object of the present invention to provide a scaffold opening simple closing device which can smoothly cope with each size of an opening formed between scaffolds and is easy to carry and handle.

[0007]

Means for Solving the Problems In order to achieve the above object, a scaffold opening simple closing device according to the present invention is configured as follows.

That is, the scaffold opening simple closing device according to the present invention provides a scaffold mounting pipe 7 which is framed in a substantially square shape.
A scaffold 6 is provided with a gap between the mounting pipe 7 and the end of the scaffold, and a simple closing device for an opening between scaffolds formed at an outer corner or an inner corner of the scaffold 6; A fold is formed on the back surface, and a closing plate 1 made of a substantially rectangular metal flat plate which is bent slightly inward along the fold to form a gentle convex curved surface, and both ends of the back surface of the closing plate 1 on the fold Side at least two places, and elastically fits into the outer periphery of the mounting pipe 7 installed near the framed scaffold 6 by pressing downward from a vertically upper position downward and vertically upward. And a clip portion 5 formed in a forked shape so that the clip portion 5 can be elastically pulled out by pulling.

According to the present invention, in the vicinity of the framed scaffold 6, the mounting plate 1 is attached to the back surface of the closing plate 1 made of a metal flat plate formed as a gentle convex curved surface in a direction orthogonal to the convex bending direction. A clip portion 5 that can be resiliently attached to and detached from the installed mounting pipe 7 is formed, and the closing plate 1 covers an opening between scaffolds.

Therefore, attachment and detachment can be easily performed, and sufficient safety in operation can be ensured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 are explanatory views of the use state of the present invention. 3 and 4 show a schematic configuration of the scaffold opening simple closing device according to the present invention.

As will be understood from the drawings, the scaffold opening simple closing device according to the present invention first has a substantially rectangular shape,
A closing plate 1 made of a flat metal plate formed as a gentle convex curved surface is provided.

A clip attached to the back surface of the closing plate 1 in a direction perpendicular to the convex curved direction and resiliently detachable from an attachment pipe attached near the framed scaffold 6. It has a part 3.

As can be understood from FIGS. 3 and 4, the structure of the clip portion 3 is a long band-shaped substrate 4 extending in a direction perpendicular to the curved portion, and is fixed to both ends of the substrate 4. And a clip piece 5 branched in a forked shape.

Here, the clip piece 5 may be usually formed of a metal member, or may be formed of a synthetic resin material.

In any case, it suffices that the clip piece 5 has elasticity and is configured to be elastically attachable to and detachable from the mounting pipe 7.

The board 4 to which the clip pieces 5 are attached at both ends is previously attached to the back surface of the closing plate 1 by welding or the like in a direction orthogonal to the bending direction in advance.

By the way, in order to form a gentle convex curved surface of the closing plate 1, a fold may be formed on the back surface of the closing plate 1 and may be bent slightly inward along the fold.

As a result, the closing plate 1 can be formed in a gentle convex curved surface. In the above, FIG.
The use state of the scaffold opening simple closing device according to the present invention will be described with reference to FIG.

In the work of assembling the framework scaffold, each scaffold 6
.. Have openings at the outgoing and incoming corners.

At the position near the scaffolds 6, an end of the scaffold 6 and a mounting pipe 7 extending horizontally are attached.

Therefore, the closing plate 1 is positioned above the mounting pipe 7 and the gap between the bifurcated clip pieces 5 of the clip portion 3 is brought into contact with the upper end of the outer periphery of the mounting pipe 7. Push down from the top.

Then, the clip piece 5 is expanded by the pressing force, and the mounting pipe 7 is fitted into the clip piece 5.

Accordingly, the closing plate 1 is disposed so as to close the opening formed between the scaffolds 6.6.

In this embodiment, two clip portions 3 are used.
The fitting pipe 7 is fitted in the fixing plate 1 so that the closing plate 1 is firmly fixed, and does not shift during the operation.

Also, for removal, the clip piece 5 can be easily attached to the mounting pipe 7 by pushing up from below.
Work such as welding, cutting, etc. is not required.

[0026]

The present invention has the above configuration. And
According to the present invention, the attachment and detachment can be performed with one touch at each construction site (each opening between scaffolds), and the production cost can be repetitively used.

Also, since there is almost no step on the scaffold, the feet of the worker are safe, and the working environment can be improved.

Further, it is possible to cope with each size of the opening formed between the scaffolds, and it is very easy to carry and handle.
