Embodiment Construction

[0010] A connection structure between a steel structure and a precast concrete slab. The steel structure 10 includes a column 11 and a beam 12, wherein the end face of the beam 12 is fixed on the column 11, and the beam body of the beam 12 is placed inside the precast concrete slab 20. The prefabricated concrete slab 20 includes a foamed concrete layer 21 and a reinforced concrete layer 22, the foamed concrete layer 21 is filled around the beam 12, the reinforced concrete layer 22 is wrapped around the foamed concrete layer 21 and the beam 12, and the beam 12 is positioned below it An elastic transition layer 30 is set between the reinforced concrete layers 22.

[0011] The beam 12 of the steel structure and the precast concrete slab 20 are made into an integrated structure. The foam concrete layer 21 can allow the beam 12 to be deformed to a certain extent. , the elastic transition layer 30 can also buffer the load transmitted from the beam 12 to the precast concrete slab 20,...

Abstract

The invention relates to the field of prefabricated houses, in particular to a connecting structure of a steel structure and a precast concrete plank. The steel structure comprises stand columns and beams, wherein the end faces of the beams are fixed to the stand columns, and beam body parts of the beams are placed in the precast concrete plank. The precast concrete plank comprises a foam concrete layer and a reinforced concrete layer, wherein the foam concrete layer is filled around the beams, the reinforced concrete layer wraps the foam concrete layer and the beams, and an elastic transition layer is arranged between the beams and the reinforced concrete layer below the beams. In this way, it can be effectively ensured that the deformation of the steel beams under the effects of working loads is not restrained by a wall body at the lower portions of the steel beams, and meanwhile cracks between the beams and the precast concrete plank are prevented. The beams and the precast concrete plank are of an integrated structure and can be hoisted at a time during splicing, so hoisting difficulty is reduced and work efficiency is improved.

Description

technical field [0001] The invention relates to the field of prefabricated houses, in particular to a connection structure between a steel structure and a prefabricated concrete slab. Background technique [0002] Prefabricated housing (assembled housing) refers to the construction of housing by industrialized production methods, that is, the stairs, exterior walls, balconies, and air-conditioning panels of the housing are all prefabricated in factories outside the construction site, and then transported to the construction site for "assembly". Among them, steel structure and prefabricated concrete slab prefabricated houses are widely used. The specific structure is that steel columns and beams are assembled into a steel frame structure, and prefabricated concrete slabs are made into walls, and then the steel frame structure and prefabricated concrete slab walls are combined. Rigid assembly. At present, the precast concrete slab is fixed on the column, and the beam is direc...
