Problems solved by technology

[0003] The steel concrete truss has high rigidity and good force transmission effect, which is very suitable for the application of large-span conversion structures, but it takes a long time in the construction of the main structure, especially for the hoisting of horizontal steel structures and the densely arranged large-diameter steel bars around the steel skeleton. Lashing and subsequent concrete pouring became the main difficulty and focus of construction

Abstract

The invention relates to a construction method for a segmental formwork hoisting system of a large-span steel reinforced concrete transfer truss. The construction method comprises main construction steps as follows: 1), embedment of a column-end pre-embedded supporting seat; 2), erection of lower steel pipe supports; 3), hoisting installation of a lower boom of the truss; 3), hoisting installation of web members of the truss; 5), hoisting installation of top booms of the truss; 6), installation of a bottom die of the lower boom; 7), steel bar binding; 8), installation of web member formworks; 9), installation of a top boom formwork; 10), pouring of concrete; 11), formwork removal. The construction method has the advantages that the operation is simple, component connection rigidity is high, disassembly and assembly are convenient and the like, and the construction method has better economic and technical benefits.

Description

technical field [0001] The invention relates to a construction method of a large-span steel concrete truss. technical background [0002] The use functions of high-rise buildings are diversified, and the use functions of rooms require large spaces and super-floor net heights. Structural conversion is usually used to meet this requirement. The steel-concrete conversion truss is a special structure. By realizing the difference between the upper and lower floors The column net structure satisfies the function of the room. [0003] The steel concrete truss has high rigidity and good force transmission effect, which is very suitable for the application of large-span conversion structures, but it takes a long time in the construction of the main structure, especially the hoisting of horizontal steel structures and large-diameter steel bars densely arranged around the steel skeleton Lashing and subsequent concrete pouring became the main difficulty and focus of construction.
