Embodiment Construction

[0052] The following is attached Figure 1-10 The present application is described in further detail with embodiment.

[0053] The embodiment of the present application discloses a high-altitude in-situ scattered construction method of a ring truss. refer to figure 1 , the high-altitude in-situ bulk construction method of the ring truss includes the following steps:

[0054] S1. Ring truss construction design

[0055] According to the terrain and the characteristics of the steel structure ring truss, the entire construction area is divided into a rigid structure area and a large-span suspended structure area, which form a complete ring.

[0056] Arrange 3 sets of flat-arm tower cranes as the main lifting equipment, and make the working range of the flat-arm tower cranes cover the entire construction area. During construction, first install the trusses in the rigid structure area to form a certain foundation for the entire ring truss structure, then install the trusses in t...

Abstract

This application relates to a high-altitude in-situ scattered construction method for a ring truss, which belongs to the technical field of building truss installation, and includes the following steps: overall design of the ring truss→stiff structure hoisting→concrete shear wall construction→ring truss support installation→ring Hoisting of the lower chord of the truss → hoisting of the inner frame of the ring truss → hoisting of the web of the ring truss → hoisting of the upper chord of the ring truss → hoisting of the roof rigid frame → the overall unloading of the ring truss and the removal of the bracket. In this application, the ring truss is divided into multiple sections according to the characteristics of the lower chord, web and upper chord, and the bracket is used as a temporary support to hoist the ring truss members to the position to be installed and assemble them in situ, which solves the problem of ring truss installation in areas with complex terrain Difficult problems have achieved good economic and environmental benefits.

Description

technical field [0001] The present application relates to the field of installation of building trusses, in particular to a high-altitude in-situ scattered construction method for ring trusses. Background technique [0002] With the development of economy and progress of society, in order to meet the needs of appearance design and use function, ring trusses are widely used in public buildings. [0003] The existing ring truss installation mostly adopts the construction method of sliding or overall lifting. For example, the ring truss construction of the newly-built National Speed ​​Skating Stadium for the 2022 Olympic Games adopts the method of direct hoisting in the north and south divisions and sliding installation in the east and west divisions. Sliding construction is mainly to move each truss block of the ring truss to the designated position of the ring track through translation equipment, and then lift these truss blocks to the support by a crane and assemble them. Th...
