Abstract

The invention relates to a novel prestress industrial stockyard canopy structure and a method for constructing the same. The novel prestress industrial stockyard canopy structure comprises a plurality of span prestress steel trusses and a plurality of spatial string beams. The span prestress steel trusses are transversely and parallelly arranged, the spatial string beams are longitudinally arranged, and the prestress steel trusses and the spatial string beams are connected with one another to form an integral structure. The method for constructing the novel prestress industrial stockyard canopy structure which is a combination structure with the prestress steel trusses and the spatial string beams includes designing the structure; determining construction schemes; grouping the trusses; splicing the steel trusses on the ground; setting temporary support scaffolds; mounting longitudinal stable trusses; constructing the spatial string beams, and the like. The novel prestress industrial stockyard canopy structure and the method have the advantages that the spatial string beams and the prestress steel trusses are combined with one another, structural merits of the spatial string beams and the prestress steel trusses are sufficiently played, and accordingly the building structure can be optimized in the aspects of modeling, utilized spaces, manufacturing cost, construction, installation and transportation.

Description

technical field

[0001] The invention relates to the field of civil engineering building structures, in particular to a novel prestressed industrial stockyard shed structure and a construction method. Background technique

[0002] The steel truss structure is elegant in shape, simple and clear, and has a clear structural force. It is suitable for large and super-long spans. It is widely used in large public buildings such as railway stations and airports, as well as industrial buildings such as large-span factories and warehouses.

[0003] Due to the influence of self-weight, vertical load and deformation, the traditional truss structure has limited span and poor economy. The concept of prestress is introduced on the basis of ordinary truss to form a string truss structure. Due to the effect of prestress, the truss produces an upward anti-arch prestress effect, which can effectively resist the self-weight and vertical dead load opposite to the anti-arch direction. , live loa...
