Connection structure of frame steel beams and composite floor slab

Abstract

The invention relates to a connection structure of frame steel beams and a composite floor slab. The connection structure comprises a connection structure of a middle frame steel beam and the composite floor slab and a connection structure of an edge frame steel beam and the composite floor slab, and the width of the lower flange plate of the middle frame steel beam is larger than those of the plate edges of an upper flange plate of the middle frame steel beam respectively by 25-30 mm; the outdoor sides of the upper flange plate and the lower flange plate of the edge frame steel beam are abreast; the width of the lower flange plate, on one side close to the indoor, of the edge frame steel beam is larger than that of the plate edge of the upper flange plate of the edge frame steel beam. According to the connection structure of the frame steel beams and the composite floor slab, steel secondary beams are reduced, the project cost is saved, the working efficiency is improved, and the construction quality is improved.

Description

technical field [0001] The invention relates to a building construction component, in particular to a connection structure between frame steel beams and laminated floor slabs. Background technique [0002] With my country's "energy saving and emission reduction" policy, housing is the focus, especially prefabricated steel structure housing brings a lot of room for development. Among many residential buildings, prefabricated steel structure housing is most suitable for factory production. The design will be , Production, construction and installation are integrated, changing the traditional "on-site construction" to "factory manufacturing". The prefabricated steel structure house has light weight, low cost, simple installation, fast construction speed, less environmental pollution during construction, good seismic performance, recyclable, economical and environmental protection, etc., which meet the requirements of the "green building" put forward by the country. [0003] The...

Problems solved by technology

The connection between the steel frame column and the concrete beam requires a corbel plate with connecting overlapping steel bars, a connecting sleeve, and a hole for passing through the steel bar on the web plate of the steel frame column. The variety of tendons brings certain difficulties to the fabrication and installation of steel columns.

[0005] The practice of the existing technology increases the amount of steel used in the prefabricated house. During the construction process, there are many types of studs and shear keys, and the steel bars of the concrete structure. The quality requirements in the installation are relatively high. Failure to complete each construction step will affect From the progress of the next process, the phenomenon of mutual restriction often occurs, which will lead to a long construction period, virtually increase manpower, material resources, and financial resources, and lead to an increase in construction costs
