Problems solved by technology

[0003] The method of sliding full hall scaffolding is one of the commonly used methods in the installation of space structures at present. However, due to the structural characteristics of the full hall scaffolding itself, there are disadvantages such as poor stability of the frame during the sliding process, and large laying area that affects mechanical operations in the field. More Applied to bolted spherical reticulated shell structures that require in-situ assembly
[0004] The large-span semi-circular pipe truss structure has the characteristics of large span, high headroom, wide coverage area and large welding volume. The method of moving the scaffolding does not have good economic and technical advantages
At the same time, if the traditional segmental hoisting method is adopted, a temporary support frame needs to be arranged under each truss, and the construction cost will be huge for the super-long pipe truss structure

Embodiment Construction

[0035] The technical solution of the present invention will be further specifically described below in conjunction with the accompanying drawings.

[0036] Such as Figure 1-10 As shown, what the present invention discloses is a construction method of a large-span semicircular pipe truss structure. During the construction process of the semicircular pipe truss structure 16, each main truss can be reasonably arranged according to the shape and force characteristics of the structure itself. It is divided into landing section 14 and middle section 15, and then the sliding track 9 is laid in the field, using the sliding construction technology of the tower sliding support frame 1, after several times of truss assembly, bracket sliding, and truss closing, until the half The circular tube truss structure 16 is fully integrated.

Abstract

The invention relates to a construction method of a tower-type sliding support frame and a large-span semicircular pipe truss structure. The tower-type sliding support frame includes several tower bodies, an operating platform, an oblique truss, a horizontal truss, cross tie rods, and a chassis bracket and sliding structure; the construction method of the large-span semicircular pipe truss structure mainly includes the following steps: 1) Determine the layout plan of the support frame; 2) Lay the sliding track, install the tower sliding support frame, and install the first assembly unit ; 3) Move the tower sliding support frame forward by two main truss distances; 4) Install the second assembled unit to complete the installation of the third assembled unit; 5) Install the pipe truss structure in the second partition. The invention effectively shortens the construction period, occupies less land, and is convenient for standardized construction.

Description

technical field [0001] The invention belongs to the technical field of steel structure buildings, and in particular relates to a tower-type sliding support frame and a construction method for a large-span semicircular pipe truss structure. Background technique [0002] In recent years, with the rapid development of my country's economy and cultural level, people have higher and higher requirements for the function, appearance and economic benefits of buildings. The long-span tube truss structure is widely used in industrial plants, logistics storage, public buildings, stadiums, dry coal sheds and other structures because of its beautiful appearance, reasonable force, and convenient construction. [0003] The method of sliding full hall scaffolding is one of the commonly used methods in the installation of space structures at present. However, due to the structural characteristics of the full hall scaffolding itself, there are disadvantages such as poor stability of the frame...
