Abstract
The invention provides an overhanging type pipe truss and an installation method of a support rod thereof.
Description
Technical Field
The invention belongs to the field of installation of a large-span pipe truss and a support rod thereof, and particularly relates to an overhanging type pipe truss and an installation method of the support rod thereof.
Background
In recent years, a large-span space pipe truss steel structure is one of important development directions of the building industry, the large-span steel structure pipe truss structure has the advantages of smooth lines, safety, practicability, rich appearance, low steel content, unique and attractive appearance and short construction period, and is widely applied to large civil landmark buildings such as exhibition centers, stadiums, airports and the like, particularly large-scale building roof systems, and most of the large-span pipe truss steel structures are adopted.
In these large-span pipe truss steel structures, the support bars are inevitably arranged below the main truss, and because the support bars and the main truss are in the same vertical plane, there is a mutual interference influence during hoisting, especially an angled diagonal brace. If hoist the bearing diagonal earlier and hoist main truss again, then the bearing diagonal needs to add interim support frame, and the angle is not good to be controlled, if hoist the main truss earlier then can cause the influence to the hoist and mount of support.
The invention aims to design a pipe truss and a mounting method of a support rod of the pipe truss, and the pipe clamp and a chain block are used for assisting, so that the support rod and a main truss can be simultaneously mounted in a hoisting mode, the mounting efficiency is improved, the crane work cost is saved, and the mounting cost is greatly reduced.
Disclosure of Invention
Aiming at the problems in the prior art, the technical scheme adopted by the invention for solving the problems in the prior art is as follows:
an overhanging type pipe truss and a mounting method of a support rod thereof are characterized by comprising the following steps:
and 6, loosening the hook by a crane, removing the hoop and the upper connecting plate of the supporting rod, and completing the integral hoisting of the pipe truss and the supporting rod thereof.
Two adjacent groups of main trusses are connected through steel pipes, and two ends of each steel pipe are of hemispherical closed structures.
And the initial hinged position between the support rod and the main truss is determined according to the installation position designed by a drawing.
The invention has the following advantages:
1. in order to avoid damage to the main truss pipe fitting, the hoop for hinging is arranged, the hoop is easy to manufacture and low in cost, and the hoisting efficiency can be effectively improved by matching with the supporting rod;
2. the hoop is arranged to connect the upper end of the support rod with the main truss in a hinged manner, so that the effect of fixing the support rod is achieved, the inclination angle of the support rod can be adjusted, and the anchor can be flexibly applied to installation of support rods with various inclination angles;
3. the lower end of the supporting rod is connected with the main truss in a hanging mode through the matching of a steel wire rope and a chain block, the angle of the supporting rod is adjusted through the chain block, and the installation precision is guaranteed;
4. the supporting rod is connected with the main truss by adopting hoop hinging and chain block hanging, so that the main truss and the supporting rod are hoisted simultaneously, and the purposes of improving hoisting efficiency and reducing cost are achieved.
