Description

Supported external hanging scaffolding

technical field

The utility model relates to the technical field of building construction, in particular to a support type external hanging overhanging scaffold.

Background technique

For a long time, the construction of high-rise buildings generally requires the use of cantilevered scaffolding. The frame body is located on the cantilever section steel. The section steel is mostly I-beam. The I-beam passes through the wall and is fixed on the floor slab by U-shaped embedded bolts. , This method requires a large number of I-beams to be used, and the I-beams must all pass through the wall, resulting in the shear wall of this layer needing to reserve a crossing hole, and the masonry wall cannot be masonry due to the obstruction of a large number of I-beams, and the outer wall is plastered. The ash and other processes cannot be constructed on this floor. The first seriously affects the progress of the project, and the second cantilever layer has a lot of potential safety hazards.

An existing invention adopts a pull-rod-type external hanging cantilever scheme, which also solves the problem of the section steel passing through the wall. In the scheme, the cantilever section steel is passed through reserved anchor holes on the floor side beams, and high-strength bolts are used to connect the section steel, and then pass the high-strength pull rod. Pulling the cantilevered end of the section steel, but its tie rod has many major safety risks: First, the tie rod needs to be made of special steel, which is not conducive to the promotion of technology, and there is no special testing organization on the market to test and evaluate its safety performance. The finished product has high protection requirements during use, and the finished product cannot be bent, bumped, cracked, etc., which is not conducive to the operation and use of workers; second, the tie rod is only connected by a high-strength bolt, and there is no spare bolt, so the safety is not high; third, section steel There are only two high-strength bolts fixed on the side beam, and there is no safety redundancy consideration. Therefore, there is an urgent need for a support-type external hanging scaffolding that is easy to install and disassemble and has high safety.

Utility model content

The beneficial effects of the present utility model:

1. The scaffold body is cantilevered on the side beam by the fixing mechanism, and the heavy-duty steel used for the cantilever scaffold body does not need to pass through the wall, which not only speeds up the construction speed, improves the safety, and does not need to block the wall again after the construction. , reducing the hidden leakage of the outer wall.

2. After the construction, all components can be recycled and reused, which maximizes the saving of construction costs.

3. The load-bearing system adopts the support type, the raw material of the support section steel is easy to obtain, the economy is better, and it is more conducive to market promotion. The number of support anchor bolts is greatly increased, which ensures the safety of the equipment to the greatest extent.

4. The tie rod adopts the bolt type, which eliminates the welding operation, is convenient for installation and disassembly, and has high safety.

To sum up, through the cooperation of the fixing mechanism with the cantilever section steel, the support section steel and the bolt-type tie rods, in the construction of the scaffold body, the load-bearing steel does not need to pass through the wall, thereby speeding up the construction progress and reducing the external cost. The hidden danger of wall leakage is higher, and the safety is higher. At the same time, after the construction is completed, the components can be recycled and reused, which reduces the construction cost and has good economic benefits.
