Description

Auxiliary device for installing prefabricated components

technical field

The utility model relates to the technical field of prefabricated buildings, in particular to an auxiliary device for installing prefabricated components.

Background technique

With the adjustment of the national construction industry policy, the prefabrication of building component production and the assembly of construction and installation have gradually become the mainstream of architectural design, production and construction in my country. At present, prefabricated or semi-prefabricated (superimposed) reinforced concrete beams, columns, shear walls, floor slabs, etc. have begun to be widely used in engineering practice. However, during the connection and assembly of prefabricated components and prefabricated components, supports are often required at the bottom of the components, and even some templates are required. For example, the beams in the intersection of prefabricated beams and prefabricated columns or prefabricated shear walls must be set in the current process. Beam bottom support; another example is when the composite floor slab intersects with the composite beam, the semi-prefabricated floor slab is only 20-25mm lapped on the edge of the beam, and the beam cannot bear the self-weight and construction load of the floor slab. The bottom of the prefabricated floor slab must be provided with supports, even template. The characteristics of fast and efficient construction of prefabricated buildings are not fully utilized. How to use the strength and bearing capacity of the installed prefabricated components as support, and directly carry the self-weight and construction load of other connected components to complete the installation of prefabricated components, reduce construction links, improve installation accuracy, and speed up construction progress? At present, it is an urgent problem to improve the efficiency of building assembly.
