Problems solved by technology

[0002] A truss is a structure composed of rods connected by hinges at both ends. It is generally a plane or space structure with triangular units composed of straight rods. The truss rods mainly bear axial tension or pressure, so that the material can be fully utilized. When the span is large, it can save material compared with solid web beams, reduce self-weight and increase rigidity. The installation of truss structures is usually supported by support frames first, and then the support frames are removed after the entire truss structure is mounted. Existing general The removal method may lead to excessive deformation of the truss, which will reduce the stability and safety performance of the entire truss structure, which is not conducive to the implementation of the project

Abstract

The invention discloses a support frame unloading method for a truss structure. The method comprises the steps that a cutting point is set at a preset position, and a support steel template is installed at the position of the cutting point; monitoring points are set around the cutting point, and a monitor is installed at each monitoring point; in cooperation with a jack, a multi-stage cutting technique is adopted for conducting cutting operation at the cutting point, and meanwhile monitoring is conducted through the monitors; the support steel template is cut off, and final unloading operationis conducted. By means of the method, the stability performance of the truss structure after the support frame is unloaded can be effectively known, the safety performance of the entire truss structure is ensured, a safe construction environment is created, and the method is worthy of wide popularization.

Description

technical field [0001] The invention relates to an unloading method, which belongs to the field of structure disassembly, in particular to an unloading method for a support frame of a truss structure. Background technique [0002] A truss is a structure composed of rods hinged at both ends. It is composed of straight rods and generally has a plane or space structure with triangular units. The truss rods mainly bear axial tension or pressure, so that the material can be fully utilized. When the span is large, it can save material, reduce self-weight and increase rigidity compared with solid web beams. The installation of the truss structure is generally supported by the support frame, and the support frame is removed after the entire truss structure is installed. The existing general The proper removal method may lead to excessive deformation of the truss, which will lead to a decrease in the stability and safety performance of the entire truss structure, which is not conduci...
