Construction method for assembling steel truss barrel-shell-structured dry coal shed

Abstract

The invention discloses a construction method for assembling a steel truss barrel-shell-structured dry coal shed and belongs to the technical field of building construction. The construction method for assembling the steel truss barrel-shell-structured dry coal shed is low in construction cost and fast in construction progress and can effectively guarantee the personal safety of constructors. The method includes firstly determining a large structural unit, determining lifting points, supporting points and span control connection points for fabricating the large structural unit through calculation and fabricating a trihedral square pyramid single body; secondly, fabricating an initial section of the large structural unit and hinging the lower end of the initial section with an assembling base point; thirdly, utilizing lifting equipment to lift the assembly end of the initial section to a height which facilitates the assembly of operators, wherein the operators perform the assembly operation on the ground until the large structural unit is completed; and lastly, taking the large structural unit as a stable system and utilizing an existing high-altitude bulk assembling method to construct and complete the assembly of the steel truss barrel shell in the length direction of the steel truss barrel shell towards both ends of the steel truss barrel-shell.

Description

technical field [0001] The invention relates to a construction method for a dry coal shed, in particular to a construction method for assembling a dry coal shed with a steel grid frame shell structure, and belongs to the technical field of building construction. Background technique [0002] In recent years, the steel grid shell structure has been widely used in the raw material stacking coal yard workshop. However, the traditional construction techniques for building the dry coal shed with the steel grid shell structure are full scaffolding high-altitude bulk method, that is, at the position where the dry coal shed with the steel grid shell structure needs to be assembled, the scaffolding is erected in advance, Then complete the whole steel grid shell structure in bulk on the scaffold. The disadvantages of this method are that the cost is high, the construction period is long, it takes up a lot of space, and it is difficult to coordinate on-site construction. For projects ...

AI Technical Summary

Problems solved by technology

This method is relatively safe for the steel grid structure and construction personnel, but it also requires a large amount of scaffolding, and the progress of the construction of the initial span is relatively slow
