Connection node of precast slabs and construction method for spliced precast slabs
The invention provides a connection node of precast slabs. The connection node comprises a first precast slab and a second precast slab connected with the first precast slab, wherein a connection piece is arranged at the joint of the first precast slab and the second precast slab; the connection piece comprises a steel reinforcement framework; and the surface of the first precast slab, the surface of the second precast slab and the node between two slabs are cast into a whole through cast-in-place concrete. Therefore, the connection node in the structure is adopted at the spliced position of the precast slabs; reinforcing steel bars are made into the steel reinforcement framework; due to the fact that small-size cast-in-place is carried out at the spliced position of the precast slabs, if field fabrication is adopted, high labor cost is consumed; however, if a precast framework is adopted, mechanized mass production can be carried out in a workshop, so that the framework can be guaranteed to coincide with the design size, and at the same time, the production cost can be substantially reduced; and after the cast-in-place concrete is cast, the integrity and the anti-seismic property of precast and spliced floor slabs are substantially improved, so that under the influence of earthquake disasters, the situation of middle-part fracture cannot be caused, and the safety performance of a building is improved.
