Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1-3 As shown, the present invention discloses a double-cable separated string tension truss, which is installed on the top of several supporting structure columns 7, including two upper chords 1 and With two lower strings 4, two adjacent upper strings 1 are connected by several upper lateral support rods 10; two adjacent lower strings 4 are connected by several lower lateral support rods 11; wherein, the upper lateral support rods 10 and the lower lateral The support rods 11 are connected by several vertical struts 2, and the adjacent vertical struts 2 are connected by diagonal rods 3; the several lower horizontal support rods 11 are connected in series by two lower chord cables 4, and each lower chord cable 4 The two ends of it are fixed on the support structure column 7 tops.

[0028] The two ends of the up...

Abstract

The invention belongs to the technical field of structural engineering, and particularly relates to a dual-cable separated type string truss and a construction method thereof. The dual-cable separated type string truss is installed on the tops of a plurality of supporting structure columns and comprises two upper chord members and two lower inhaul cables. The two upper chord members and the two lower inhaul cables are installed on the supporting structure columns. The two adjacent upper chord members are connected through a plurality of upper transverse supporting rods, and the two adjacent lower inhaul cables are connected through a plurality of lower transverse supporting rods. The construction method comprises the steps that machining and manufacturing of the rods of the truss and purchase of the inhaul cables and steel pull rods are conducted in a factory according to the building and structure design; then, splicing of the string truss is completed on a construction site, the inhaul cables and the steel pull rods are tensioned to be of the design value, and setting of prestress is completed; and finally, the string truss is wholly hoisted in place, and a support is fixed. The novel dual-cable separated type string truss and the construction method thereof have the advantages that the structural type is novel, the form is attractive, the overall stability is superior, the structural coordination performance is good, and construction is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a double-cable separated string string truss and a construction method thereof. Background technique [0002] With the progress of society, the development of science and technology, and the improvement of economic and cultural levels, people have put forward higher requirements for large-span spatial structures. The current building structures with small and medium spans can not only meet the functional requirements of the large space of public buildings, but also cannot meet people's increasing aesthetic requirements, which requires the development of new structural forms to meet architectural functional and aesthetic requirements. [0003] Tension string structure is a kind of space structure system widely used at present. Its main feature is that the upper rigid substructure (or component) and the lower flexible steel cable are connected by struts, ...
