Embodiment Construction
[0022] Below by embodiment, in conjunction with accompanying drawing, the technical scheme of the present invention is described further specifically, as Figure 1-2 As shown, a pipe truss hoisting method based on concrete columns is characterized in that it includes the following steps:
[0023] Step 1. Before hoisting, bury the concrete column at the preset installation position of the pipe truss, re-measure the foundation elevation of the pipe truss, and install a pre-embedded steel plate on the contact surface between the concrete column and the pipe truss for subsequent welding between the pipe truss and the concrete column Fix, mark the vertical positioning axis on the pre-embedded steel plate according to the design position of the central axis of the pipe truss surface to be installed, and mark the vertical positioning axis on the surface to be installed of the pipe truss, and weld the lower part of the embedded steel plate Control panel 3, the installation height of t...

The invention provides a pipe truss hoisting-in-position method based on a concrete vertical column. On the basis of the concrete vertical column preinstalled and designed based on the designed position of a pipe truss, the pipe truss is hoisted in position; a pre-embedded steel plate is installed on the concrete vertical column, a detachable structural part is installed on the pre-embedded steelplate, the pipe truss is rapidly installed under the joint action of a crane and a chain block, thus the assembling efficiency of the pipe truss is improved, and the assembling quality is ensured; andby utilizing the joint action of a pipe truss bottom elevation control plate, pipe truss vertical axis adjusting plates and steel wedges which are arranged on the concrete vertical column, the elevation and the vertical axis of the pipe truss are precisely positioned, and the installing precision and efficiency of the pipe truss are improved.
Description
technical field [0001] The invention belongs to the field of installation and placement of pipe trusses, and in particular relates to a method for installation and placement of pipe trusses based on concrete columns. Background technique [0002] At present, in the process of hoisting pipe trusses in large venues such as large stadiums, railway stations, and terminal buildings, the traditional tire frame installation requires a lot of auxiliary materials, the auxiliary structure is complicated, the production is difficult, and the construction cost is high. The present invention intends to involve a A side hoisting and positioning method of a rectangular pipe truss based on a concrete column can ensure installation accuracy, improve construction efficiency, reduce fabrication difficulty and construction cost, and ensure construction safety. Contents of the invention [0003] For the problems existing in the prior art, the technical scheme adopted by the present invention f...
