Steel frame mounting method for glass roof

Abstract

The invention discloses an installation method for lighting roof steel frame. The method takes a roof outside a side span beam of a lighting roof cavity as an assembly platform. Two supporting beams of the lighting roof are detachably provided with a translational slide way respectively. A first span main beam and a second span main beam of the lighting roof steel frame are placed on the translational slide way of the assembly platform at intervals; the two span main beams are fixed together by a purline so as to form a first spaced steel frame; and a translational tractor translates the first span steel frame for one interval to the lighting roof cavity on the translational slide way; the processes are repeated, and then a second spaced steel frame is assembled and translated until the last spaced steel frame is assembled and translated; and finally, the translational tractor is used for translating the integrated lighting roof steel frame on the translational slide way, and the installation is finished until the steel frame covers the lighting roof cavity. The installation method avoids insecurity and instability of aloft work, does not need to build, detach or reinforce a temporary bracket, avoids the hoisting of large-scale component, avoids the aloft work, reduces the cost and improves the security of construction.

Description

technical field [0001] The invention relates to a method for installing a building steel frame, in particular to a method for installing a daylighting roof steel frame. Background technique [0002] Modern buildings, especially public buildings, mostly pursue novelty, simplicity, modernity, and transparency, and their roofs are also regarded as the fifth facade, which has received more attention. It is more and more common to use daylighting roofs on roofs. Most of the skeleton adopts steel structure. [0003] The installation method of existing daylighting roof steel frame has two kinds. The first method is the high-altitude bulk method, that is, scaffolding is erected. The construction personnel stand on the scaffolding, hang the components of the lighting roof steel frame, and then assemble the lighting roof steel frame. This method is simple, but high-altitude operations will be carried out on temporary supports (scaffolding), which has hidden dangers in construction s...
