Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a sliding curing plate for protecting against falling objects that is installed between a building and an external or internal framework scaffold during construction work.

(Prior Art) During construction work, etc., a cloth board for protecting against falling objects is installed between a building and an external or internal framework scaffold. Conventionally, methods for attaching this cloth board to internal framework scaffolding, etc. include fixing it with brackets (bracket method), fixing it with a hinge that can be semi-rotated from the framework scaffolding side (rotating method), and
As shown in Publication No. 56-41013, a cloth board is placed across the sides of two support rods arranged horizontally and in parallel, and each support rod is slidably inserted into a supporting body (scaffold auxiliary frame). The following methods have been adopted.

(Problem that the invention aims to solve) However, with the bracket method, since it is a fixed type, it must be removed when it becomes unnecessary depending on the construction process, resulting in poor work efficiency. Furthermore, the gap between the fall protection cloth board and the framework scaffolding cloth board is large, which is dangerous.

In addition, although the rotating type does not require the trouble of removing it, since the width of the cloth board is constant, it cannot be used when the distance between the building and the scaffolding frame changes greatly depending on the construction process. Furthermore, when storing the space between the frame and the scaffolding,
It remains as a protrusion on the surface and becomes an obstacle in some types of form work.

Furthermore, the scaffold auxiliary frame shown in Japanese Utility Model Publication No. 56-41013 is mainly intended to prevent workers from falling, and simply has a notch formed at the tip of the holding body for storing cloth boards. If a large external force is applied to the cloth plate, the tip of the holding body may open.
It is not strong enough to be used as a work floor in a steel frame or reinforced concrete structure.

This idea was devised to solve the above-mentioned problems.It can be installed, assembled, and dismantled more easily, has a large required strength, can be used as a work floor, can be mass-produced, and is suitable for construction work. The purpose of the present invention is to provide a sliding type curing board for protecting against falling objects that can completely close the gap between a framework scaffold and a structure that changes depending on the situation.

(Means for solving the problem) The sliding type curing plate for protecting against falling objects of this invention is
Attach both ends of supporting members made of two section steel horizontally and parallelly to the connecting plates that extend laterally from the clamps fixed to the frame of the framework scaffold, and attach the front side of each supporting member. A guide member having a groove-shaped cross section is provided with openings facing each other, and rail members provided at both ends of a steel cloth plate are slidably fitted into the groove-shaped opening of the guide member. It is something.

In the above configuration, the rail member fitted into the guide member is positioned by pressing the bolt attached to the end of the rail member against the support member.

Further, when the steel cloth plates are arranged continuously in the longitudinal direction of the cloth plates, guide members are provided on both sides of the tip of the support member.

(Example) This invention will be described below based on an example shown in the drawings.

This sliding type curing plate for protecting against falling objects is
Two support members 1, two guide members 2, 2
It is composed of a book rail member 3 and a steel cloth plate 4.

The two supporting members 1 arranged horizontally and in parallel are made of lightweight section steel (channel steel, lip channel steel, square steel tube), and clamps 5, 6 are attached to both ends thereof. In the illustrated embodiment, a coupling plate 7 is provided between the support member 1 and the clamps 5 and 6, and the coupling plate 7 is provided so as to protrude laterally so as not to interfere with the framework scaffold 9. and,
A guide member 2 having a groove-shaped cross section is provided on the opposite side of the tip of each support member 1 along the longitudinal direction of the support member 1 so that the openings thereof face each other. This guide member 2 has a length approximately half that of a rail member 3, which will be described later, and is fixed to the support member 1 by welding or the like. A rail member 3 made of channel steel and slightly smaller than the width and height of the guide member 2 is fitted into each guide member 2.
It is designed to be able to slide freely inside. Rail members 3 are provided on both sides of the steel cloth plate 4 by welding, bolting, or the like. At least one steel cloth plate 4 is required, but a plurality of steel cloth plates 4 can be provided in parallel according to the length of the rail member 3. (In the example shown in the figure, two sheets are provided.)
Further, as shown in FIGS. 4 and 5, a stopper 8 is provided at the inner end of the rail member 3 to prevent the cloth board 4 from falling forward.

Next, the installation procedure of this sliding type falling object protection curing plate will be explained.

First, attach the clamp 5 to the building site on the opposite side of the building frame of the scaffolding 9 and the clamp 6 to the building site on the building side, place the supporting member 1 between both clamps 5 and 6, and place the supporting member 1 It is fixed by passing the L-shaped pin 10 through the hole in the connecting plate 7 fixed to the clamp plate 7 and the hole in the connecting plate 7', 7'' on the clamp 5, 6 side (see Fig. 4).Then, both supporting members are fixed. 1,
A rail member 3 for supporting and fixing the cloth board 4 is inserted into the guide members 2, 2 at one tip. Note that a scaffold board 11 is attached between the framework scaffolds 9, 9.

When storing the cloth board 4, the rail member 3 is fixed by inserting the bolt 12 attached to the side end of the rail member 3 into the hole drilled in the support member 1. During work, the bolt 12 is inserted into the support member 1. Fix it by pressing it on.

(Effect of the invention) The gap between the framework scaffold and the building can be completely closed.

Since the cloth board is a sliding type, it can be flexibly adapted to the gap width that changes depending on the construction process, and it is compact when stored.

A guide member is provided at the tip of the support member that is subjected to concentrated loads, and since the support member is made of a composite material,
It has a large required strength and is suitable for use on work floors. Additionally, since it can be used as a work floor, the need for work in unstable postures is greatly reduced, greatly improving safety and work efficiency.

When assembling and dismantling the formwork, the fabric board is attached to the formwork,
Since it can be used as a temporary storage space for various materials such as single pipes, a working path can be secured and safety for workers is improved.

It is easy to put in and take out cloth boards, and it does not require the hands of professionals, so the work process is shortened and there is no need to leave unnecessary materials behind.

When the curing plates of this invention are installed consecutively in the horizontal direction, the gaps between the cloth plates are small, so it is possible to reliably prevent objects from falling, and the curing performance is also good.

Installation, assembly, and disassembly work is easy.

When stored, there are no protruding objects between the scaffolding and the frame, which will not impede various types of work.

It can be used for frame scaffolds of various widths simply by changing the length of the supporting members.
