Abstract

The invention relates to a precast slab, and a method for connecting the precast slab with the precast slab and a beam. The method for connecting the precast slab with the precast slab and the beam ischaracterized in that the precast slabs at two sides of the beam are fixed by pins through respective pre-embedded groove-shaped connecting pieces on end surfaces of supporting ends of the precast slabs and the beam, and self-compacting concrete strips are poured into a slab joint between the first precast slab and the second precast slab in order to make the first precast slab, the second precast slab and the beam connected into an integral body, so the large-area wet working problem of existing assembled building composite floor slab technology is solved, the disadvantages of complex construction process, long construction period and poor quality are overcome, and the problems of easy damaging of horizontal reinforcing bars, onsite reinforcement assembling and onsite pouring of slab concrete are also solved.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a prefabricated panel and a connection method between the prefabricated panel and the prefabricated panel and beams. Background technique [0002] Prefabricated buildings are the development direction of engineering construction. It adopts refined construction, which not only saves energy and reduces pollution, but also improves efficiency and quality. [0003] In order to ensure the integrity of the floor slab, the existing prefabricated floor slab still mostly adopts the method of prefabricated slab plus laminated layer, that is, the lower half of the floor is prefabricated in the factory, the upper half of the concrete is cast on site, and the prefabricated lower half The floor slab only plays the role of the bottom formwork for the upper half of the floor slab, and the construction of the upper half of the floor, that is, the laminated layer concrete, still requires on-...
