Embodiment 1

[0043] An integral laminated slab composite beam, comprising a plurality of composite sub-beams that can be connected to each other, the composite sub-beams include a prefabricated layer, the prefabricated layer has a plurality of overlapping steel bars 2, and a plurality of prefabricated sub-beams The sides of the layers are all provided with joints 3, and the overlapping steel bars 2 are exposed from the joints 3; the tops and sides of multiple composite sub-beams are covered and connected by the post-casting layer 7; the prefabricated layer and the post-casting Layers 7 are connected by truss bars 1 . The post-cast layer 7 is connected to at least one straight side of the steel beam 5 through a shear connector 6 . The scheme disclosed in the present invention solves the problem of insufficient integrity of the prefabricated slab 4 by combining the prefabricated slab 4 with the post-cast layer 7, uses the truss steel bar 1 as an auxiliary connection between the prefabricated...

Embodiment 2

[0059] A method for manufacturing an integral laminated slab composite beam, comprising the following steps:

[0060] - weld the shear connector 6 on the upper flange of the steel beam 5;

[0061] -Processing the prefabricated slab 4, when the prefabricated slab 4 is processed, the truss reinforcement 1 needs to be pre-placed in the slab, a part of the truss reinforcement 1 is embedded in the prefabricated slab 4, and the other part is embedded in the post-cast layer after the post-cast layer is poured;

[0062] - Place one end of the prefabricated slab 4 on the upper flange of the steel beam 5, and the shelving size is set according to the design requirements.

[0063] -Leave a certain length of overlapping steel bars 2 at the splicing parts of adjacent prefabricated panels 4. The position of the overlapping steel bars 2 is also the joint 3 between adjacent prefabricated panels 4. A part of the formwork should be laid under the joints 3 .

[0064] - laying prefabricated sla...

Abstract

The invention discloses an integrated laminated slab composite beam, comprising a plurality of composite sub-beams which can be connected with one another, each composite sub-beam comprises a prefabricated layer, a plurality of lap joint steel bars are arranged in each prefabricated layer, splicing seams are formed in the side faces of the prefabricated layers, and the lap joint steel bars are exposed out of the splicing seams. The tops and the side parts of the plurality of composite sub-beams are covered and connected by a pouring layer. The prefabricated layers and the pouring layer are connected through truss steel bars. The pouring layer is connected with at least one straight side face of a steel beam through shear-resistant connecting pieces. According to the integrated laminated slab composite beam, the problem that the integrity of a prefabricated slab is insufficient is solved, the integrity of a laminated slab composite beam component is improved, and an unexpected state isnot prone to occurring.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an integral laminated plate composite beam. Background technique [0002] Steel-concrete composite beams take advantage of the tensile properties of steel and the compressive properties of concrete, and have the advantage of light weight compared to ordinary concrete beams, so they are widely used in building structures. [0003] There are still a lot of wet work in the field construction of traditional composite beams, and a lot of formwork is needed during construction. With the advancement of prefabricated building structures in recent years, a new type of integral laminated slab composite beam has emerged. The integral laminated slab composite beam also has the mechanical properties of traditional composite beams. The steel beam is connected as a whole through shear connectors, and the laminated slab is composed of prefabricated slabs and post-cast layers. As a...
