Description

[Detailed Description of the Invention] This invention relates to temporary scaffolding used when performing nailing, caulking, etc. on wall panels as part of construction work such as prefabricated buildings.

Conventionally, temporary scaffolding used in prefabricated buildings etc. to facilitate construction work includes ladders, stepladder scaffolding,
Log scaffolding, frame scaffolding, etc. were used.

However, these conventional scaffolds have complex structures that lack ease of assembly, are unstable during installation, and have safety issues, and change from time to time in response to the progress of work. However, this method inevitably involves disadvantages such as difficulty in moving and reaching the working position appropriately and quickly.

In order to solve this problem, for example, Utility Model No. 54-8
A ladder according to Publication No. 022 has been proposed, however, according to this, scaffolding supports that can be attached and detached from the side beams of the ladder,
Since the scaffolding board is supported by the support member, it is not only troublesome to attach and detach the scaffolding board, but also, if the mounting position is different, there will be a difference in level in the installation direction of the scaffolding board, which is dangerous.

Furthermore, a scaffold according to Japanese Utility Model Publication No. 54-115124 has been proposed, in which the upper part is attached to a ladder-like body part in the inner direction, and the lower part In this case, an accessory scaffold is attached that is supported by a support rod that can be freely adjusted in engagement with the horizontal bar, so as with the above case, the work of attaching and removing the accessory scaffold is not only troublesome, but also Since the support rod protrudes outward from the main body, it is dangerous for workers to ascend and descend, and the structure is complex and inconvenient to handle.

Therefore, this idea was devised to eliminate this drawback of the conventional temporary scaffolding, and a plurality of horizontal bars are constructed between a pair of vertically long bars to form a ladder body, and this ladder body On one of the vertically long rods constituting the vertically long rod, a handrail rod along the vertically long rod is connected via an appropriate number of mounting rods installed at predetermined intervals between the handrail rod and the vertically long rod, and each The upper part of the longitudinal rod has a bent part bent towards the wall of the structure, and the upper end of this bent part has a hook body having a hooking piece that can be nailed to the upper edge of the wall. A swingable base body for grounding is removably connected to the lower end of each vertical rod, and at a predetermined position of each vertical rod, the contact body that comes into contact with the wall surface has a long The gist of this is that the support rods are attached in a row so that the height can be adjusted freely.

An embodiment of this invention will be described below with reference to the drawings.

A pair of vertically elongated rods 1 made of pipe material or the like are formed with bent portions 2 provided at the upper portions thereof.

As is clear from Fig. 1, the shape of this bent part 2 is inclined obliquely upward from the starting end and directly upward at the terminal end, and its bending direction is the direction of the wall W in the building to be constructed. None.

A ladder body is formed by installing a plurality of horizontal bars 3, which are used for footholds, etc., at appropriate intervals between the longitudinal bars 1.

Among the vertically long rods 1 constituting this ladder body, a handrail rod 4 is connected to one of the left and right (right side in the illustrated example) vertically long rods 1 along the vertically long rods 1.

An appropriate number of mounting rods 5 are placed between the vertical rod 1 and the handrail rod 4.
For example, by constructing three scaffolds as in the illustrated example, it is formed so that the scaffolding board S can be placed thereon.

However, if a plurality of mounting rods 5 are provided, the height of the scaffolding board S can be adjusted, and it can be adapted to the situation at the work site.

At the appropriate position of each vertically long rod 1, there is a supporting rod 6 which is to be brought into contact with the wall W to support the ladder body in the bending direction of the upper bent part 2 and at an angle orthogonal to the vertically long rod 1. , for example, the central part and the lower end part are connected to each other.

Since this support rod 6 also aims to improve the work efficiency of the worker by forming a working space between it and the wall W, it is necessary to form an interval equivalent to the interval formed by the bent part 2. It is preferable to use a length that allows for

A hook body 7 formed to be hooked onto the upper end of the wall W is attached to the upper open end of the bent portion 2 at the upper part of the vertically long rod 1.

As shown in FIG. 2, this hook body 7 is formed by a substantially inverted U-shaped hook part 8 and a fixing part 9 to the vertically long rod 1 connected to this. Attach the fixed part 9 -
They may be connected by tightening with a nut N via a bolt B.

Note that the strength of the hook portion 8 can be improved by providing an appropriate number of ridges on the hook portion 8.

As shown in FIG. 2, a latching piece 11 having a latching hole 10 is provided on the tip side of the hook part 8 in advance, and by nailing it to the wall W through this latching piece 11, the hook body can be fixed. 7 can be ensured.

A base body 12 for grounding to the ground is attached to the lower end of the vertically long rod 1.
are attached to each.

As shown in FIG. 3, the base body 12 is composed of a base plate 13 and a pair of clamping pieces 14 that are erected on the base plate 13 to pivotally clamp the lower end of the vertically long rod 1. ,
The clamping piece 14 and the vertically elongated rod 1 are connected to each other in a swingable and detachable manner by tightening a nut through a bolt B.

By drilling a circular hole 15 in the substrate 13 in advance, it is possible to anchor it to the ground via the circular hole 15.

The support rod 6 that should come into contact with the wall W to support the ladder body
has an abutment body 16 attached to its open end, the length of which can be adjusted freely.

This contact body 16 includes a contact piece 17 as shown in FIG.
It consists of a bolt B fixed to this contact piece 17, and the bolt B can be attached by screwing into a nut N that is embedded and fixed in advance in the open end of the support rod 6.

Of course, the bolt B may be screwed into the support rod 6 by threading a female thread on the inner periphery of the open end thereof.

If a through hole 18 is drilled in the contact piece 17 in advance, the contact #-16 can be fixed to the wall W through the hole by means such as nailing, and shaking during work etc. can be ensured. can be prevented.

Next, a method of using the temporary scaffolding according to the invention constructed as described above will be explained.

First, when the base body 12 is used with the base body 12 grounded on the ground, as shown in FIG. Rod 4
5 on the right side.
A scaffold can be formed by passing the scaffolding board S through the frame.

In this case, since the base body 12 and the vertically long rod 1 are swingably connected, even if the ground surface is a slope, the vertically long rod 1
can be placed along the wall W.

Also, it is nailed to the wall W via the hook piece 11 of the hook body 7,
By anchoring the base body 12, it is possible to prevent the scaffold from collapsing during work.

In addition, in a prefabricated building, when constructing a wall W such as a wall panel at a relatively high location on the second floor, hook the hook 7 on the upper edge of the wall W. Scaffolding can be formed by fixing the scaffolding board and passing the scaffolding board S over it.

In this case, a bent portion 2 is provided at the top of each vertically long rod 1,
In addition, since the support rods 6 are provided at appropriate positions, a working space is formed between the scaffolding board S and the wall W, so that the movement of the worker can be made smooth. It is also suitable for safety measures.

Even if the surface of the wall W is not smooth, the length of the abutting body 16 attached to the open end of the support rod 6 is adjustable by, for example, rotating the port B.
The base body 1 can be reliably supported in contact with the wall body W.
2 itself is removably connected to the lower end of the vertically elongated rod 1 of the ladder body, so when the ladder body itself is not set on the ground, the base body 12 can be removed.

In addition, by nailing the hook body 7 to the wall W via the hook piece 11, the hook body 7 can be securely hooked.
Furthermore, by nailing and fixing to the wall W using the hooking piece 11, suspension support from the middle of the wall W is also possible.

Furthermore, by using a ladder body consisting of 1 vertically long rod and 3 horizontal rods, it can be used alone as a ladder, or by combining multiple pieces as appropriate, it is possible to promote improvement in work efficiency. .

Not only that, but the handrail rods 4, which are connected along one vertical rod 1 that covers the ladder body, ensure the safety of workers when going up and down the ladder body, and also ensure the safety of workers when going up and down the ladder body. Since the mounting rod 5 for passing the board S to the rack does not protrude from the handrail rod 4, unlike the conventional method, it is not dangerous for the worker, and there is no need to attach or remove it; the scaffolding board S can simply be passed to the rack. Therefore, it is easy to handle.

As described above, according to this invention, scaffolding can be formed at appropriate positions depending on the situation at the work site and the progress of the work, and it is not only highly versatile. However, it is possible to provide a scaffold with excellent workability and high safety, and since the structure is simple, it can produce practical effects such as being able to provide a robust and inexpensive product.
