A prefabricated beam slab and its construction method

Abstract

The invention discloses a fabricated beam plate and a construction method. The fabricated beam plate comprises a laminated beam and laminated plates connected to two sides of the laminated beam. A groove is arranged in the middle of the top surface of the laminated beam, and two sides of the groove are respectively provided with a pre-embedded first connecting steel plate. The edges on the two sides of the laminated beam are provided with concave platforms for connection with the laminated plates. One end of each laminated plate is provided with a flange extending along the plane, and a secondconnecting steel plate is embedded in the upper portion of the flange. During installation, firstly the laminated beam is lifted, then the laminated plates are lifted, the flange of each laminated plate is installed in the corresponding concave platform of the laminated beam, the first connecting steel plate and the second connecting steel plate are connected through an anchoring steel plate, anda concrete layer is cast in place on the plane composed of the laminated beam and the laminated plates to form a floor slab. The anchor bolt embedding form is adopted to connect the laminated beam and the laminated plates closely. The construction is convenient, no slurry leakage or crack is generated, and the shearing resistance of connection nodes of the laminated beam and the plates is improved.

Description

technical field [0001] The invention belongs to the field of building construction, and relates to a beam-slab construction method, in particular to an assembled beam-slab and the construction method. Background technique [0002] For ordinary composite beam-slab joints, the concrete is poured after the composite slab falls on the composite beam and steel bars are laid. The working efficiency of the traditional method is low. When the concrete is poured, the steel bars are prone to deviation and grout leakage is very easy to occur, which has a great impact on the quality of the concrete forming and the structural stability of the joints. There is no technology that can well solve this problem in the prior art, which greatly affects the construction quality and construction progress. Contents of the invention [0003] The purpose of the present invention is to provide a prefabricated beam and slab and its construction method. The laminated beam and the slab are stably conn...
