Embodiment Construction

[0025] Hereinafter, exemplary embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0026] figure 1 is a structural schematic diagram of a steel pipe roof truss 10 according to an exemplary embodiment of the present invention.

[0027] Before the steel pipe roof truss is assembled, it is necessary to arrange the assembly sequence of the rods reasonably according to its structural characteristics. according to figure 1 The structural form of the steel pipe roof truss shown in , determine the assembly sequence as follows: lower chord plane truss assembly - upper chord plane truss assembly - upper chord plane truss lifting - lower chord plane truss arching - upper and lower chord plane truss member assembly.

[0028] The method for assembling the trusses of a huge-span steel pipe roof according to an exemplary embodiment of the present invention will now be described in detail, and the method mainly includes the following st...

Abstract

The invention provides an enormous-span steel tube house truss assembling construction method which comprises the following steps: step one: an assembling platform is arranged at a node of a truss; step two: firstly, a bottom cord plane truss is assembled; after the assembling of the bottom cord plane truss is completed and passes the inspection, an upper chord plane truss assembly is carried outat the upper part of the bottom cord plane truss; after the assembling of the upper chord plane truss assembly is completed and passes the inspection, the upper chord plane truss is welded; step three: after the upper chord plane truss is welded, the upper chord plane truss is wholly lifted in the air; and after the upper chord plane truss is lift, the bottom cord plane truss is welded; step four: the bottom cord plane truss is arched nearby each node by using a lifting jack; step five: member bars between the upper chord plane truss and the bottom cord plane truss are assembled, the assembling of the member bars between the upper chord plane truss and the bottom cord plane truss is carried out in the air, and an assembling sequence is as follows: upright rods are firstly installed and then slanting poles are installed.

Description

technical field [0001] The invention relates to the technical field of building construction, more specifically, to a construction method for assembling steel pipe roof trusses with a span greater than or equal to 114m. Background technique [0002] In recent years, due to the advancement of science and technology and the wide application of new materials and technologies, many large public buildings and industrial plants have adopted steel pipe rods with rich shapes, light structures, simple force transmission, high rigidity, light weight, and single rods. Cross-tube truss structure. This type of structure is used in long-span buildings due to its huge size, which causes certain difficulties in the assembly of trusses. [0003] Present assembling method mainly contains: 1, the high-altitude loose assembly method; 2, the ground loose assembly method; 3, the high-altitude block (strip) assembly method; 4, the ground block (strip) assembly method. These several assembly meth...
