Embodiment Construction

[0025] The present invention is further illustrated by specific examples below.

[0026] A large-span special-shaped space grid tube truss integral sliding construction method is characterized in that: it comprises the following steps;

[0027] Step 1. Determine the truss construction site according to the design drawings;

[0028] like figure 1 shown,

[0029] Step 2. Set up a trestle-type beret 1 in the building foundation pit, and lay a concrete strip foundation 2 outside the foundation pit;

[0030] Step 3. Lay four parallel tracks 3 on the trestle-type beret 1 and the concrete strip foundation 2;

[0031] Step 4. According to the structural calculation and design height requirements, set the assembled support frame 5 and the sliding support frame 4 on the four parallel tracks 3;

[0032] like figure 2 shown,

[0033] Step 5. Use a crane to build the truss 7 based on the sliding support frame 4 and the assembled support frame 5, wherein the assembled support frame 5...

Abstract

The invention relates to the field of steel structure monolithic architecture construction, in particular to an overall sliding construction method for a large-span special-shaped space grid pipe truss. The method is characterized by comprising the following steps that 1, a truss erecting field is determined; 2, a trestle type Bailey frame is erected in a foundation trench, and a concrete strip foundation is laid outside the foundation trench; 3, four parallel rails are laid; 4, spliced supporting frames and sliding supporting frames are arranged; 5, the truss is erected through a hoist; 6, vertical and horizontal unloading operating is carried out on the erected truss; 7, the sliding supporting frames are connected with ejectors; 8, synchronous control devices are arranged between the ejectors; 9, the ejectors are started, and the sliding supporting frames are made to synchronously slide to the target position; 10, the sliding supporting frames are dismounted, and a truss support is mounted. Through the steps, the large-span special-shaped space grid pipe truss can be mounted in a sliding mode, the truss is stressed evenly in the sliding mounting process, and deformation is not prone to being caused.

Description

technical field [0001] The invention relates to the field of steel structure integral building construction, in particular to a large-span special-shaped space grid pipe truss integral sliding construction method. Background technique [0002] With the development of the national economy, large-span space steel structures have been widely used in my country, such as stadium structures, high-speed rail station awnings, etc. During the construction of these types of steel structures, the traditional construction method is to use large-scale mechanical hoisting. In recent years, with the development of steel structure construction technology, steel structure slip technology has been applied in such steel structures. The current steel structure slip mostly adopts the cumulative slip method, and the construction operation efficiency is low, time-consuming and labor-intensive. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an integral ...
