Prefabricated light steel concrete slab-column structure and its construction method

Abstract

The present invention provides a prefabricated light steel concrete plate column structure and a construction method thereof. The prefabricated light steel concrete floor of each storey is divided into a plurality of floor sections according to the column spaces of prefabricated light steel concrete columns and are connected to form a main body structure, and at the same time a prefabricated light steel concrete wall type support is arranged between two prefabricated light steel concrete columns in each storey. In an overall structure, the prefabricated light steel concrete plate bears a vertical load, at the same time sufficient horizontal stiffness is provided, the prefabricated light steel concrete columns bear the vertical load transmitted by the prefabricated light steel concrete floor, and the prefabricated light steel concrete wall type support only bears a lateral load. Structure resistant-lateral rigidity is provided in a normal use state, and the effect of energy consumption shock reduction is achieved under an earthquake effect. The prefabricated light steel concrete plate column structure and the construction method have the advantages of high prefabricated assembly rate, low construction cost, few field wet operation, and high architectural adaptability.

Description

technical field [0001] The invention relates to the field of architectural design, in particular to a prefabricated light-steel concrete slab-column structure and a construction method thereof. Background technique [0002] The prefabricated light-steel concrete structure is a structural type that conforms to the industrialized production mode of construction, and has the outstanding advantages of standardized design, prefabricated production, and assembled construction. [0003] At present, the structural systems such as assembled integral concrete frame, concrete frame-shear wall, and concrete full shear wall have the following shortcomings or problems: [0004] 1) During the construction process, there are a large number of concrete cast-in-place wet operations, the process is complicated, and the construction efficiency is not high; [0005] 2) The component prefabrication rate is too low (15% to 40%), and it is difficult to improve; [0006] 3) There are too many type...

AI Technical Summary

Problems solved by technology

[0004] 1) During the construction process, there are a large number of concrete cast-in-place wet operations, the process is complicated, and the construction efficiency is not high;

[0005] 2) The component prefabrication rate is too low (15% to 40%), and it is difficult to improve;

[0006] 3) There are too many types and specifications of prefabricated components, which increases the cost of factory prefabrication accordingly, and the construction cost remains high, making it difficult to promote

[0007] The application of the current prefabricated concrete slab-column structure alleviates the above contradictions to a certain extent, but since the joints between the prefabricated slab and the prefabricated column need sufficient rigidity to improve the lateral resistance of the structure, the joints of the prefabricated slab and the prefabricated column are stressed It is relatively complex, and assembly design and construction are difficult; in addition, the existing slab-column structure has limited lateral resistance and is not suitable for building high-rise buildings, and its promotion and application have obvious limitations
