Description

Technical Field

[0001] The utility model relates to the field of prefabricated components, in particular to a composite plate type concrete prefabricated component. Background Art

[0002] Prefabricated components refer to building components that are first processed and formed in a factory or workplace and then transported to the site for installation and splicing. There are many types of prefabricated components, and composite slab prefabricated wall components are one of them. Composite slab prefabricated wall components are made up of two concrete wall panels stacked together, and the stacking method is to use steel trusses to connect the concrete slabs on both sides. When prefabrication is completed in the factory, there is a cavity between the slabs. After installation in place on site, concrete is poured in the cavity. The wall formed by prefabricated and cast-in-place concrete that bears the overall force is the composite slab shear wall.

[0003] The current composite slab prefabricated wall components do not have a structure to limit the concrete slabs on both sides when they are combined and connected. When pouring concrete, the cavity between the two concrete slabs is likely to cause the concrete slabs on both sides to be compressed and offset, thereby affecting the quality of the overall wall panel after the two concrete slabs are combined and connected. Therefore, those skilled in the art provide a composite slab concrete prefabricated component to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the present invention is to provide a composite prefabricated concrete component of a composite slab type to solve the problems raised in the above background technology.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The composite slab type concrete composite prefabricated component can limit the connection protrusion and be installed in the connection groove by means of the connection groove and the connection protrusion.
