Problems solved by technology

The shapes of these buildings are becoming more and more novel, and the structures are becoming more and more complex. The roofs of some large buildings are designed with glass or transparent tiles to increase the appearance and use functions. The roof trusses of these lighting wells have large spans and high installation heights. Hoisting of crane equipment Due to the limited length of the crane arm, it is difficult to hoist the truss in place at one time

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with specific embodiments.

[0032] Such as Figure 1-3 As shown, a method for installing high-altitude large-span steel trusses is characterized in that the trusses are lifted to the required vertical height outside the building, and then the trusses are slid in place by the air sliding method, installed and fixed, and pulled up. cable wind rope; specifically include the following steps:

[0033] 1) Set up a rail 1 with a "concave" cross section at the installation place of the support 4 embedded parts at both ends of the large-span steel truss 3, and make the two rails 1 with a "concave" cross section parallel to each other. The two parallel tracks can make the two ends of the large-span steel truss 3 slide in the track without deviation or overturning.

[0034] 2) Apply lubricant and sprinkle spherical steel marbles 2 on the track 1 with a "concave" cross section to provide sufficient lu...

Abstract

The invention discloses an installation method for high-altitude large-span steel trusses. The method comprises the steps that the trusses are lifted to a demanded vertical height outside a building; then, each truss is slid in place through an overhead slide method, and hawsers are installed, fixed and pulled; and above operations are repeated till all the high-altitude large-span steel trusses are installed. According to the invention, the problem that large crane equipment cannot lift high-altitude components of a building light well roof in place can be solved; the method is simple and requires fewer steps; the construction period is shortened; the construction cost is reduced; and the method has very good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of steel structure construction, and in particular relates to a method for installing a high-altitude large-span steel truss. Background technique [0002] With the rapid development of my country's economy and the improvement of people's material living standards, their requirements for spiritual life are also getting higher and higher. In recent years, my country has built a large number of cultural public buildings, including sports centers, theaters, etc. The shapes of these buildings are becoming more and more novel, and the structures are becoming more and more complex. The roofs of some large buildings are designed with glass or transparent tiles to increase the appearance and use functions. The roof trusses of these lighting wells have large spans and high installation heights. Crane equipment hoisting Due to the limited length of the crane arm, it is difficult to hoist the truss in place at one time...
