Problems solved by technology

[0003] Using the "bracket method" construction technology, the existence of a large number of vertical supports makes it impossible to realize high-altitude and low-altitude synchronous, non-interfering three-dimensional operations, and this process requires high-altitude assembly of steel structure trusses due to many parts, there are serious high-altitude falling objects Security risks

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] For example, the upper beam of a bridge tower is a prestressed reinforced concrete cavity beam structure spanning the left and right tower columns. The beam is 9 meters high, 43.8 meters long and 8 meters wide. It is a super-high-altitude super-long giant beam structure,

[0022] Such as figure 1 As shown, the overall lifting system of the super-high-altitude super-long giant beam truss method of the present invention includes a lifting bracket 1, a formwork truss 2 and a lifting power system 3, and the formwork truss 2 includes a main body truss 21 and an end fixed truss 22. The end fixed trusses 22 are fixed on the vertical structures 4 on both sides of the giant beam 5, the lifting bracket 1 is fixedly arranged on the fixed trusses 22 at both ends, the lifting power system 3 is fixed on the lifting bracket 1, and the lifting power The system...

Abstract

The invention discloses an integral hoisting system for a superaltitude overlong jumbo beam by a truss method and a construction method thereof. The system comprises a hoisting support, a formwork truss and a hoisting power system, wherein, the formwork truss comprises a main truss and end fixing trusses; the end fixing trusses are fixed on vertical structures of two sides of the jumbo beam; the hoisting support is fixed on two end fixing trusses; the hoisting power system is fixed on the hoisting support; the hoisting power system is connected with the main truss through a hoisting steel wire. Through the integral hoisting system for a superaltitude overlong jumbo beam by a truss method, slipping solid operation of an upper beam structure and a deck girder, which can not be realized by the traditional support method, can be smoothly realized, high / low altitude synchronization non-interfering solid operation can be realized, and potential safety hazard of a jumbo high-altitude falling object existing in truss assembling on high altitude can be reduced while construction process is greatly accelerated.

Description

technical field [0001] The invention belongs to the technical field of building and bridge engineering construction, and relates to the construction technology of super-high-altitude super-long giant beams, in particular to a super-high-altitude super-long giant beam truss method overall lifting system and the construction of super-high-altitude super-long giant beams by using the system construction method. Background technique [0002] At present, the "bracket method" construction technology is generally used in the construction of ultra-high altitude and ultra-long giant beam structures at home and abroad, that is, the construction technology of combining vertical steel structure trusses by erecting vertical support systems. [0003] Using the "bracket method" construction technology, the existence of a large number of vertical supports makes it impossible to realize high-altitude and low-altitude synchronous, non-interfering three-dimensional operations, and this process...
