Solid web type horizontal steel beam high-altitude installation temporary fixing structure and implementation method

Abstract

The invention discloses a solid web type horizontal steel beam high-altitude installation temporary fixing structure and an implementation method, and belongs to the technical field. The structure comprises a 1 # solid-web type horizontal steel beam and a 2 # solid-web type horizontal steel beam, an upper flange of the 1 # solid-web type horizontal steel beam extends towards the part, close to oneside, of the 2 # solid-web type horizontal steel beam relative to a lower flange; a lower flange of the 2 # solid-web type horizontal steel beam extends towards the part, close to one side, of the 1# solid-web type horizontal steel beam relative to the upper flange of the 1 # solid-web type horizontal steel beam, and the extending length is equal to the extending length of the upper flange of the 1 # solid-web type horizontal steel beam; and the upper surface of the upper flange of the 1 # solid web type horizontal steel beam is fixedly connected with an upper flange ridge stop block, the upper surface of the lower flange is fixedly connected with two lower flange ridge stop blocks, a web is arranged on the side, opposite to the 1 # solid web type horizontal steel beam, of the 2 # solidweb type horizontal steel beam, and the web is located between the two lower flange ridge stop blocks. The operation is simple, the solid web type horizontal steel beam high-altitude installation temporary fixing structure is convenient to use and reliable, the applicability is high, the construction cost and unsafe factors are reduced, and the construction quality and the construction efficiencyare improved.

Description

technical field [0001] The invention relates to the technical field of high-altitude installation between two steel girders of a building structure, in particular to a temporary fixing structure for high-altitude installation of a solid-web horizontal steel beam and an implementation method. Background technique [0002] With the advancement of construction technology, the forms of building structures are becoming more and more diverse, and the combination of steel structures and steel structures with concrete structures is becoming more and more widely used. The structure of section steel as beam and column is mostly used in new large-scale public buildings with the characteristics of large span, high floor height, and large changes in high and low spans. It has the advantages of light weight, convenient and efficient construction, etc. [0003] However, the traditional steel girder installation method is generally directly hoisted by tower cranes, but for ultra-long steel ...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional steel girder installation method is generally directly hoisted by tower cranes, but for ultra-long steel girders with a length of more than 15m, the transportation and hoisting are difficult, and it is necessary to consider the lifting weight of the tower crane and the weight limit of the steel girder itself , using multiple tower cranes to lift steel beams at the same time, it is necessary to prepare multiple tower cranes on site at the same time, the construction workload of tower crane foundation and tower crane installation and disassembly is large, and the construction cost is greatly increased. The design and layout of the installation have a great influence, which increases the difficulty of construction design, reduces the safety and reliability of construction, makes it inconvenient for installers to operate, and reduces work efficiency.
