Method for assembling fixed ends of scaffold of large-volume triangular variable-section tubular truss structure

Abstract

The invention discloses a method for assembling fixed ends of a scaffold of a large-volume triangular variable-section tubular truss structure. The method is characterized in that: a concrete base is poured on the ground; a large tubular truss, of which two ends are provided with triangular sections, is horizontally assembled above the concrete base; after finishing the assembly, the whole is pulled by a hoisting mechanism, and a rod piece between the two sections is assembled above a scaffold supporting system at a certain angle; and after finishing the assembly, tail sections of the fixed end sections on two sides are dismounted, and are mounted to the start sections of the next section of assembled structural member. The method has the advantages that: under the condition that pre-assembly cannot be performed on the construction site, the assembly precision is guaranteed as much as possible; furthermore, the two fixed end sections are positioned, and the rod piece between the two sections is used as a pivot, so that the manufacturing material of the scaffold is saved.

Description

technical field [0001] The invention relates to a method for assembling the fixed end of a tire frame of a large-volume triangular variable-section pipe truss structure. Background technique [0002] At present, more and more large triangular variable cross-section steel structure buildings have been applied, and the existing construction methods are mostly temporary support on the ground in bulk technology, setting up a reliable support system, lifting parts, and installing at high altitudes, gradually completing the construction of buildings. method, the construction period is extended, and high-altitude operations are very dangerous and inefficient. In recent years, triangular variable-section pipe trusses have also been assembled with ground tire frames for overall installation. However, the current assembly of large triangular variable-section pipe truss ground tire frames has the characteristics of small regularity and multiple tire frame numbers and specifications. F...

Problems solved by technology

[0002] At present, more and more large triangular variable cross-section steel structure buildings have been applied, and the existing construction methods are mostly temporary support on the ground in bulk technology, setting up a reliable support system, lifting parts, and installing at high altitudes, gradually completing the construction of buildings. method, the construction period is extended, and working at heights is very dangerous and inefficient

In recent years, triangular variable-section pipe trusses have also been assembled with ground tire frames for overall installation. However, the current assembly of large triangular variable-section pipe truss ground tire frames has the characteristics of small regularity and multiple cases of tire frames and specifications.

For projects with tight schedules and limited sites, there are some difficult problems in the method of assembling the ground in large sections and lifting as a whole, such as the difficulty in arranging a wide variety of assembled tire frames in a limited construction site
