Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as Figure 1-7 shown.

[0030] A construction method for super-large-span prestressed pipe truss ground-hanging cables in the air. According to the position of the end of the cable, the prestressed pipe truss is divided into three sections A, B, and C, such as figure 1 as shown; first hoist sections A and C to the design position (such as image 3 , 4 ), and then assemble B1 and B2 sections on the ground into B section (such as Figure 5 , 6 ), the cable is initially tensioned after the cable is hung on the ground, such as Figure 7 As shown, after the preliminary tensioning is completed, the two machines will lift section B to the design position and dock with sections A and C in the air. After the docking is completed, install the contact truss, and finally stretch the cables to the design requirements.

Abstract

The invention discloses a construction method for ground cable hanging and aerial butt joint of an ultra-large-span prestressed pipe truss. The construction method is characterized in that the ultra-large-span prestressed pipe truss is divided into three sections A, B and C according to the characteristics of the ultra-large-span prestressed pipe truss structure, each section is assembled on the ground through a jig frame, and after the procedures of jig separation, transportation, overturning, hoisting and the like, the sections A and C are hoisted to a designed position at first; the sectionB is divided into a subsection B1 and a subjection B2 and spliced on the ground through a jig frame, after jig separation, the subsections B1 and B2 are sequentially hoisted to a ground support framefor aerial butt joint, a prestressed steel inhaul cable is hung, and the steel inhaul cable is primary tensioned according to a simulation checking result; and after primary tensioning, the section Bis hoisted to the designed position through two machines to be in aerial butt joint with the section A and the section C, after butt joint is finished, a connecting truss is installed, the steel inhaul cable is finally tensioned according to the simulation checking result, and the ultra-large-span prestressed pipe truss is installed. The construction method highlights the characteristics of highconstruction speed, low cost, low safety risk, high construction quality and the like in the operation process.

Description

technical field [0001] The invention relates to a steel structure construction technology, in particular to a large-span reticulated shell structure construction technology, in particular to a construction method for super-large-span prestressed pipe truss ground-hanging cable aerial docking. Background technique [0002] In recent years, with the continuous growth of my country's steel production, pipe trusses are being used more and more widely. In order to build an ecological civilization and reduce environmental pollution, the proportion of super-long-span cylindrical pipe trusses in coal storage sheds is increasing. Especially the prestressed tube truss structure, because of its beautiful shape, good structural stability, and high rigidity, perfectly combines the functional requirements, sensory requirements and economic benefits of the building. [0003] At present, super-large-span prestressed pipe trusses are mostly assembled in sections on the ground, and then hoiste...
