Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a scaffolding device that is constructed directly on the balcony of a high-rise building, such as an apartment building.

(Prior Art) In the construction of high-rise buildings such as condominiums, framework scaffolding that is constructed from the ground and covers the entire building has conventionally been used for all exterior work including work on balconies.

(Problem that the invention aims to solve) However, there are few works that can be done on the balconies of condominiums etc. without necessarily using framework scaffolding constructed from the ground, and it is not necessary to take the trouble to do this kind of work. When constructing a framework scaffold from the ground, the construction of the scaffold becomes a large-scale task.

This invention was developed in view of the above points, and the purpose is to provide a scaffolding device that can be constructed independently for each floor, in order to simplify the use of scaffolding for work on the balconies of condominiums, etc. shall be.

(Means for solving the problem) The gist of this invention to achieve the above purpose is to provide a supporting column and a locking hole on the side that can be attached to and detached from a locking body protruding from the building side. A scaffolding device for a building is characterized in that the upper surface is provided with an insertion hole for the lower end of the support column, and a box-shaped support column receiving metal fitting having a holding member for the lower end of the support column is provided in the body.

(Function) Therefore, in this invention, as a scaffold for work on the balcony of an apartment building, etc., the scaffolding can be independently composed for each layer that requires it.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

Figure 1 is a perspective view of the supporting column receiving metal fitting of this invention.
FIG. 2 is a side view showing the mode of use, and FIG. 3 is a front view of the same.

In the figure, 1 is a support column receiving metal fitting, 2 is a support column, and 3 is a locking body.

The support column receiving metal fitting 1 is used in combination with the support column 2 to hold the lower end of the support column, and is shaped like a box, with a locking hole 5 provided in the side surface of the support column that can be detachably attached to the locking body 3, and a locking hole 5 in the upper surface. An insertion hole 6 into which the lower end of the support column is inserted, and a holding member 7 for the lower end of the support column corresponding to the insertion hole 6 are provided inside the body.

The support column 2 is attached with a scaffold board 4 and a single pipe 1' used as a handrail, and is made of a tube body of an appropriate thickness.

The locking body 3 protrudes from the building side, and has a head 3b on a rod-shaped body 3a, and the head 3b is attached to the outer wall of the building, for example, the outer wall of the balcony A on each floor of an apartment building. They are placed in advance in a protruding state and arranged in at least two stages, upper and lower.

Therefore, the locking hole 5 of the above-mentioned support column receiving metal fitting 1
, a large hole 5a large enough to allow the head 3b of the lock 3 to pass through is formed in the lower part, and a cut groove 5b in which the lock body 3a is locked is connected to the upper part of the hole 5a.

The holding member 7 in the support post holder is a single-tubular member that is inserted into the hollow of the support post 2, and the upper end of this holding member 7 is attached to the support post 2 to prevent the support post 2 from coming off. An L-shaped locking groove 7a is provided in which the joint pin 8 provided in a transverse manner falls into and is locked by horizontal rotation of the support column 2.

Although not shown in the drawings, the scaffolding board 4 can be attached to the support column 2 by a well-known appropriate attachment means, and the scaffolding board 4 can also be attached directly to the support column receiving bracket 1. I have to.

In addition, the length of the support column 2 is such that it extends at least above the support column receiver 1 installed on the building side of the upper floor, and the upper end of the support column is set upright on the support column receiver 1 of the upper floor. An appropriate clamp 9 is used to clamp it along the lower part of the support column.

In the above configuration, this invention is designed to attach the support column receiving fitting 1 by locking it to the locking body 3 buried in advance in the outer wall surface of the balcony A during exterior work on the balcony A of a condominium or the like.
The support column 2 is erected by holding the lower end of the support column in the support column receiver 1, and the scaffold board 4 is directly attached to the support column receiver 1, and the single pipe 1' that is used as a handrail is attached to the support column 2. Install and use.

(Effects) As described above, this invention provides the following effects.

(1) Scaffolding can be easily set up and used from the balcony side of each floor where the work is needed when working on the exterior of a high-rise building, such as a condominium.

(2) The support pillars to which the scaffolding board is attached can be set with one touch to the receiving metal fittings, and the supporting pillars are prevented from being pulled out from the receiving metal fittings, resulting in high safety.

(3) Scaffolding boards can be attached directly to the support column brackets, making it convenient for work that extends the balcony surface outward.

(4) Since the scaffolding is constructed independently for each floor of the building, it is possible to dismantle the lower floors first.

(5) It can also be used on walls where there is no space to construct a framework scaffold from the ground.

(6) Compared to constructing a framework scaffold from the ground,
Temporary material damage, associated assembly and disassembly fees, and transportation costs can be reduced.
