Embodiment Construction

[0014] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0015] see figure 1 and figure 2 , a roof truss hoisting method, according to the following steps:

[0016] 1) First assemble n roof trusses in the site to form a roof truss system 1, where n≥2.

[0017] 2) Weld at least two supporting poles 2 at the bottom of the lower chord of the roof truss system 1 along the length direction of the roof truss system 1 .

[0018] 3) Select four lifting points 4 on the upper chord of the roof truss system 1, and then use the crane 5 to hoist the roof truss system 1 to the position of the embedded plate on the top of the prefabricated column 3 to complete the installation.

[0019] 4) Disassemble the roof truss system 1 and the supporting pole 2, and use the crane 5 to lift the p...

Abstract

The invention discloses a roof truss hoisting method. The roof truss hoisting method is conducted according to the following steps that (1) in a site, n roof trusses are first assembled to form a rooftruss system, and n is equal to or greater than 2; (2) at least two carrying poles playing a supporting role are welded at the bottom of a lower chord of the roof truss system in the length directionof the roof truss system; (3) four hoisting points are selected on an upper chord of the roof truss system, and then the roof truss system is hoisted by a crane to the position of a pre-embedded plate at the top of a prefabricated column to complete the installation; and (4) the roof truss system and the carrying poles playing the supporting role are split, and the carrying poles are hoisted to the ground by the crane. The roof truss hoisting method does not require workers to work high above the ground, the hoisting stability of the multiple roof trusses is improved by welding the carrying poles playing the supporting role, and thus the roof truss hoisting method is simple, convenient and high in efficiency and safety.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a roof truss hoisting method. Background technique [0002] With the development of my country's economy, industrial, civil, municipal and other construction fields are booming, and the roof truss structure is widely used. In order to ensure the construction period and avoid rework, the hoisting efficiency of the roof truss must be high. At present, the following methods are generally used for hoisting roof trusses: 1. Hoist the corresponding two and a half roof trusses in place, and send people to the assembling position with a crane for assembling work. 2. Assemble the roof truss in advance on the site, and then hoist a whole roof truss as a whole. However, the disadvantages of these two methods are: workers are required to work at heights, the labor efficiency is low, the roof truss is unstable during hoisting, and the safety is low. Therefore be badly in need of a kind ...
