Abstract

The invention provides a local laminated slab connection joint. The connection joint includes two prefabricated plates. The end parts of the prefabricated plates are provided with grooves. Bottom grooves are arranged in the grooves. The bottom grooves in the two prefabricated plates are arranged opposite to each other and form a through groove. First reinforcing ribs are arranged in the bottom grooves. Second reinforcing ribs are arranged in the grooves. The upper sides of the second reinforcing ribs are provided with third reinforcing ribs perpendicular to the second reinforcing ribs. The prefabricated plates are provided with top steel bars. The top steel bars extend from the side walls of the grooves to the upper ends of the grooves of the corresponding prefabricated plates. The upper sides of the top steel bars are provided with fourth reinforcing ribs. The local laminated slab connection joint can meet force transmission requirements of a two-way slab, and the rigidity and the bearing capacity of a connecting part are large.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a connection node of a partially laminated plate and a construction method thereof. Background technique [0002] Concrete composite slab is a slab structure that combines prefabricated concrete slab and cast-in-place floor, which has the advantages of fast construction and saving formwork. The side splicing of one-way laminated slabs should adopt close splicing joints with additional steel bars, while the side splicing of two-way laminated slabs should adopt post-cast tape joints. Most of the floor slabs of residential buildings are two-way force-bearing slabs, and the traditional laminated slab structure cannot realize the two-way force-bearing function of laminated slabs. If the two-way stressed laminated slab is designed as a one-way slab, due to the stiffness of the post-casting layer, the floor slab still transmits force as a two-way slab first; after the joint position ...
