Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a framed wooden house, 2 × 4.
To prevent a worker's fall accident from above the beam of a building, when assembling a pillar or beam of a small-scale building such as a wooden house or a steel-framed house, or when a worker moves between beams. The present invention relates to a hanging scaffolding metal fitting for a small-scale building attached to a beam.

[0002]

2. Description of the Related Art Generally, steel frame and steel frame reinforced concrete steel frame suspension scaffolds are disclosed in Japanese Utility Model Publication No. 57-48.
The scaffolding device as described in Japanese Patent No. 916 is constructed.

However, in a small-scale building such as a wooden house or a steel frame house, conventionally, there is no scaffolding device, and the scaffolding device is used as a scaffolding when assembling the pillars and beams of the building or when moving a beam between workers. Uses an assembled beam, and an operator rides on the beam to perform an assembly operation or walks on the beam to move, and no measures have been taken to prevent the worker from falling.

[0004]

The above-mentioned conventional suspension scaffolding device for steel frames requires a large and wide space and is heavy and cannot be used for a small-scale building at all.

The use of the latter assembled beam of the above-mentioned conventional type for scaffolding is risky for a worker to fall because he / she is working without a main rope. The swinging work of the hanging arrow that can be seen easily causes a crash, which may lead to the worst fatal accident, and an improvement order has been issued by the Labor Standards Inspection Office.

[0006]

The present invention has not been conventionally taken at the time of joining the columns and beams of a small-scale building such as a wooden house and a steel frame house, and at the time of moving a worker between beams. As a worker's fall prevention measure, it can be easily and firmly attached to the beam to form a suspended scaffold, which contributes to the worker's safety measures and improves workability and work safety, and is lightweight and easy to handle. An object is to provide an easy suspension scaffolding metal fitting for small-scale buildings.

That is, one side vertical rod is provided below one side of the horizontal rod.
The other side vertical rods are provided below the other side to form a hook body that is loosely fitted to the beam of the building from above, and the one side vertical rod of the hook body is provided with a female screw with a screw hole in the left-right direction. Screw the tightening bolt into the female screw and provide the operating part on the outer side of the tightening bolt, and attach the press washer to the inner side.The other side vertical rod has the scaffolding plate receiving rod to which the handrail support is attached at the tip. At the time of joining work of pillars and beams of small-scale buildings such as wooden houses and steel-framed houses, by attaching the base part to construct hanging scaffolding metal fittings for small-scale buildings,
When a worker moves between beams, etc., a suspending scaffold that can be easily and firmly attached to the beam to construct a suspending scaffold can be constructed as a measure to prevent a worker's fall, which has not been taken conventionally. In addition to improving safety and safety during work,
For the purpose of making it light and easy to handle, screw a tightening bolt into the female screw of the vertical rod on one side of the hook body and attach the scaffold plate support rod with a handrail prop to the vertical rod on the other side, and attach it to the appropriate part of the beam of the building. Fit the above-mentioned hook body to and fasten it with tightening bolts to fix the hanging scaffolding bracket to the beam, place the scaffolding board on the scaffolding plate receiving rod of the hanging scaffolding metal fitting, and attach the handrail rod to the handrail rod, It was realized by attaching a middle cross and others and constructing a suspension scaffold on the beam.

(D) Light weight and easy to handle.

(E) The mounting of the suspension scaffold is sure and firm.

(V) It can be attached to beams of various widths and is highly versatile.

(G) For the scaffolding plate, either wooden or metal scaffolding plate can be used, which is useful in operation.

(2) Simple construction and easy manufacturing at low cost.

(3) By constructing a suspension scaffold on a beam on the ground, and lifting the beam with a suspension scaffold by a crane or the like to fix it to a column, the worker can safely work at a high place.

(4) When the scaffold plate receiving rod is provided on the hook body so that the scaffold plate can be adjusted up and down, the scaffold plate can be adjusted up and down and the height of the scaffold plate can be adjusted so as not to interfere with the work on the lower floor. It is convenient.
