Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to a cross lock for building construction and a construction method thereof. Background Art

[0002] Cross lock refers to a building construction component used to fix and connect different precast concrete components. Specifically, it is a connector consisting of four or six square or rectangular metal rods and metal plates, usually made of angle iron or mild steel. These metal rods are welded into a slightly curved shape to adapt to the curved surface of different precast concrete components, thereby fixing and connecting the components.

[0003] In short, cross locks play an important role in building construction, especially in the construction of precast concrete components. When selecting cross locks, the required quantity and material should be determined according to the shape, size and construction environment of the components, and ensure that they can correctly connect the components to ensure construction efficiency and the quality and stability of the concrete components.

[0004] Generally, the cross locks used to connect different concrete components are connected by welding or by pre-setting bolts and bolt holes on the surface. Different cross locks need to be aligned when the components are installed. The relative positions of the components are limited by the reserved bolts and bolt holes during installation, and fine-tuning cannot be performed according to the actual situation on site before and after installation, so there are limitations in use.
