Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a precast composite floor slab with a pressure relief structure. Background Technique

[0002] A precast composite floor slab is an assembled monolithic floor slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. The composite floor slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for the decoration of the finishing layer, and is suitable for high-rise buildings and large-span buildings with relatively high requirements for overall stiffness.

[0003] In the prior art, when installing a precast composite floor slab, a hoisting device is used to bind and lift the precast composite floor slab, and then the precast composite floor slab is slowly lowered until it is lapped on the supporting beam frame.

[0004] However, due to the large weight of the precast composite floor slab, when the precast composite floor slab is lifted and placed on the supporting beam frame, the precast composite floor slab impacts the supporting beam frame, not only resulting in the concrete at the corners of the precast composite floor slab being knocked and damaged, but also the vibration generated during the falling affecting the stability of the connection of the supporting beam frame.
