Abstract
The invention discloses a key type integral connection structure for precast hollow slabs. Ends of the hollow slabs are connected by forming concrete keys via notch butt joint and high-pressure concrete pouring. The precast hollow slabs are connected into an integral structure, so that the integral connection structure is high in structural strength, joint seams are less prone to cracking, building quality is improved greatly and using performance is enhanced.
Description
Technical field
The present invention relates to construction engineering technical field, be specifically related to precast hollow slab key formula Integral connection structure.
Background technology
The plate end of existing prefabricated hollow wall board and prefabricated hollow floor is all flat end face, prefabricated hollow wall board relies on cement mortar and cracking resistance network material filling chink with prefabricated hollow wall board, prefabricated hollow floor with being connected of prefabricated hollow floor, thereby its syndeton intensity difference, can not form Integral connection structure, particularly the as easy as rolling off a log cracking of seam, affect apparent mass and functional performance.
Summary of the invention
Technical problem to be solved by this invention is: solve the problem that above-mentioned prior art exists, and provide a kind of precast hollow slab key formula Integral connection structure, make the overall structure that is connected to become between precast hollow slab, structural strength is high, be not easy to occur gaping of joints, greatly improve construction quality and functional performance.
The technical solution used in the present invention is: precast hollow slab plate end is formed outer little interior large notch, adopt notch docking, high pressure pouring concrete to form the concrete key being connected between precast hollow slab and precast hollow slab, beam, post and connect.
In technique scheme, described notch adopts circular, polygon.
In technique scheme, precast hollow slab edges of boards chamfering filling cement mortar.
The present invention forms outer little interior large notch with precast hollow slab plate end, install when connecting, adopt on-the-spot high pressure pouring microdilatancy pea gravel concreten, form a concrete key, closely connect two boards or tight junction plate and beam, post, make it to occur mutual up and down, left and right bidirectional displacement, connecting sewing can the cracking phenomenon under general External Force Acting.Simultaneously, utilize the chamfering filling cement mortar of edges of boards, strengthened the contact surface of cement mortar and precast plate, increased the bonding force of mortar and precast plate.
