Background technique

With the rapid development of my country's economy, various high-rise or super-high-rise buildings in cities are rising, and cantilevered scaffolding is a common construction technology in the construction of external scaffolding. The existing cantilevered scaffolding construction technology cannot meet the stress requirements of the cantilevered scaffolding while the construction of the stairwell, the side wall of the elevator room and the constrained edge wall column is difficult, and the amount of I-beam is increased.

Utility model content

The purpose of this utility model is to provide a triangular support device for the cantilevered scaffolding, so that the cantilevered scaffolding can reduce the installation difficulty of I-beams and improve the overall stability of the cantilevered scaffolding in the stairwell, the side wall of the elevator room, and the restraint edge wall columns and other parts. , At the same time, the consumption of I-beam is saved, and the deficiencies of the existing technology are overcome.

For achieving the above object, the technical scheme of the present utility model:

A triangular support device for cantilevered scaffolding, comprising: a horizontally arranged cantilever I-beam, one end of which is pre-buried in the upper part of a shear wall; a pre-embedded steel plate is pre-buried in the lower part of the shear wall; Embedded bolts are pre-buried in the lower part of the shear wall, and are used to fix the pre-embedded steel plate on the shear wall; I-beam diagonal bracing, one end of which is welded on the pre-embedded steel plate, and the other end is welded on the pre-embedded steel plate. It is supported and welded at 200mm from the far wall end of the cantilevered I-beam, and the I-beam diagonal brace and the shear wall form an included angle greater than or equal to 40° and less than or equal to 50°.

As a further improvement, the depth of the cantilevered I-beam pre-embedded in the shear wall is 150-200 mm.

As a further improvement, the I-beam diagonal brace and the shear wall form an included angle of 45°.

Compared with the prior art, the new technology adopted by the present utility model enables the cantilevered scaffolding to reduce the difficulty of installing I-beams in the stairwell, the side walls of the elevator room, and the restraint edge wall columns, etc., and improves the overall stability of the cantilevered scaffolding. The cross-arrangement of a plurality of I-beams at the corners results in insufficient end anchoring. The utility model has the advantages of fast construction progress, no anchoring ends of the I-beams in the building, avoiding blockage of fire passages, no special requirements for labor, and easy installation and disassembly. .
