Assembled concrete filled steel tubular column steel frame-beam column wall residence system

Abstract

The invention relates to an assembled concrete filled steel tubular column steel frame-beam column wall residence system. The system is formed by assembling a rectangular cross-section column body, anH-shaped steel beam, a steel beam column wall, a floor slab, a base layer inner wall body and an enclosure outer wall. In order to achieve the purpose that a beam column is not exposed indoors, the column body with the narrow side width smaller than the thickness of the base layer inner wall body is adopted to be connected with the beam column, and the outer side of the long side of the column body is coated with a fireproof coating to achieve the thickness equal to the thickness of the wall body; the steel beam with the flange width smaller than the thickness of the base layer inner wall body is selected to be connected with the wall body, a steel mesh is laid on the outer side of a steel beam web to prevent cracking, a cavity between the steel mesh and the steel beam web is filled witha filler, a leveling layer is arranged along the outer side of the steel mesh to the surface of the base layer inner wall body, and the steel beam is integrally flush with the surface of the base layer inner wall body; the steel beam column wall integrates the functions of the column, the support and the enclosure wall into a whole, a larger anti-side force can be formed, and the requirements suchas equipment opening, and equipment pipe penetrating can be met; and the assembled concrete filled steel tubular column steel frame-beam column wall residence system has the advantages that the beamcolumn is not exposed indoors, the spatial layout is reasonable, pipeline arrangement of pipelines are convenient, and the like.

Description

technical field [0001] The invention belongs to the field of prefabricated steel structure buildings, and mainly relates to a prefabricated steel pipe concrete column steel frame-beam column wall residential system. Background technique [0002] The structural components of steel structure buildings have high strength and small component cross-sections, which can increase the usable area by about 5-10% compared with concrete structures. In addition, the factory produces prefabricated components with high component precision. The construction is not restricted by seasons and the construction period is short. The recovery of investment is fast, while traditional concrete buildings consume a lot of natural resources (yellow sand, stones, water), serious environmental pollution, and rising labor costs, making steel structure buildings have become the main development direction of residential buildings in my country. [0003] The structural system of steel structure housing mainly...

Problems solved by technology

No matter what kind of building system is adopted, columns, beams, and walls as the supporting body are indispensable. In steel structure buildings, all kinds of stressed components are factory prefabricated parts. Different sizes, it is inevitable that there will be insufficient matching of components during construction and assembly

Especially for columns and beams as the main stress-bearing components, in order to ensure that the bearing capacity meets the design requirements, the design dimensions of columns and beams are often larger, usually greater than the thickness of the wall. When connecting, the beams and columns of the indoor building are usually exposed, and the connection nodes of various shapes are formed. The exposed beams and columns not only affect the aesthetics of the architectural design, but also cause inconvenience to the indoor space layout due to the occupation of the indoor space, especially The occupancy of the indoor usable area is very unacceptable to house buyers

[0004] In the existing design of prefabricated steel structure building systems, most designers mainly focus on how to shorten the construction period, reduce costs, how to improve load capacity and other related issues, while ignoring the needs of residents for building space layout and aesthetic requirements , the neglect of building functionality has become a common phenomenon in steel structure houses
