Truss combined steel-concrete structure building system

Abstract

The invention relates to the field of prefabricated buildings, and discloses a truss combined steel-concrete structure building system. The truss combined steel-concrete structure building system comprises a truss combined structure, wallboards and floor slabs. The truss combined structure comprises combined columns and composite beams. The truss combined structure is composed of a plurality of unit three-dimensional trusses and unit plane trusses. Each unit three-dimensional truss is formed by enclosing four unit plane trusses, and the four corners of each unit three-dimensional truss are thecombined columns formed by fixedly connecting vertical components. The combined columns of upper and lower floors are correspondingly connected through connecting pieces I to form the combined columns which are through up and down. Horizontal components of the upper and lower floors are connected through connecting pieces II to form the composite beams. According to the truss combined steel-concrete structure building system, the performance advantages and characteristics of steel and concrete are fully exerted, the structural combination is optimized, the structural beams and the structuralcolumns are designed in a segmented mode through the technical innovation idea of firstly breaking and then erecting and finally combining, a more reasonable main body structure is formed after installation and combination, force transmission is effectively carried out, the stress performance of the structure is improved, and the anti-seismic capacity is better.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a truss-combined steel-concrete structure building system. Background technique [0002] The building structure mainly includes two structural forms: steel structure and reinforced concrete structure. These two structures have their own advantages and disadvantages. [0003] Steel structure has the advantages of light weight, large bearing capacity, good structure and easy processing. It can be directly applied to fabricated steel structure buildings. However, steel structure is easy to rust and has poor fire resistance. It needs a separate process to solve the problems of rust prevention and fire prevention. Since the steel beams and steel columns of the steel structure are continuous structural components, it is easy to transmit the sound of the upper and lower floors, but it is difficult to sound-proof and sound-proof, which affects the comfort of use.

Problems solved by technology

This simple superimposed assembly design, construction and installation method does not give full play to the performance advantages of good integrity, high strength and easy forming of concrete. The price of concrete itself is doubled, and the secondary transportation and cost from the factory to the construction site are also increased; a large number of metal sleeves are used to connect components, which increases the construction cost and the man-hours for installing metal sleeve connections and grouting, and also reduces Construction and installation efficiency; at the same time, the grouting inside the metal sleeve is a closed and concealed construction. It is difficult to completely discharge the air inside the sleeve, and it is easy to produce cavities that are not dense, and it is impossible to detect the density and quality monitoring of the grouting, which ensures the reliability of the connection of the stressed steel bars. Sex poses uncertain security risks
