Description

An adjustable multi-point anti-drop device assembled on the outer wall of a building and its use method

technical field

The invention relates to the technical field of building construction, in particular to an adjustable multi-point anti-falling device assembled on the outer wall of a building and a use method thereof.

Background technique

At present, building components refer to the various elements that make up a building. If a building is regarded as a product, then building components refer to the parts in this product. The components in a building mainly include: floor (roof) surfaces, walls, columns , foundation, etc., which are not the same as the concept of structural components. Structural components are the elements that constitute the structural skeleton, of course, including beams, slabs, walls, columns, foundations, etc. Divided into flexural members, compression members, tension members, torsion members, and compression-bending members.

When the anti-fall device of the existing building components is in use, it is necessary to drill holes in the building wall to insert the fixing bolts, and then fix the anti-fall device to the user and the fixing bolts respectively, so as to prevent the staff from slipping and falling. The length of the connecting rope of the drop device cannot be extended, and the installation position of the fixing bolt is a fixed point. If it needs to be moved from a long distance, it is necessary to open multiple holes on the wall and drive the fixing bolts for the staff to connect. The surface damage is too large, and the degree of freedom of the staff is reduced after the staff is connected to the building components through the anti-fall device. Therefore, we propose an anti-fall device for building components used in construction.
