Tower type truss installing structure and method without cooperation with altitude hoisting equipment

Abstract

The invention relates to a tower type truss installing structure and a tower type truss installing method without cooperation with altitude hoisting equipment. The method comprises the step of overlapping a plurality of truss standard knots from bottom to top, wherein each truss standard knot consists of a plurality of vertical chord members (1 and 4), and the chord members (1 and 4) are fixedly connected with each other by web members (2 and 3). The structure and the method disclosed by invention are characterized in that one chord member (4) of the tower type truss is concurrently taken as a climbing rack and an attaching support for an assistant crane, and the chord members (1 and 4) and the web members (2 and 3) of the tower type truss are installed by the assistant crane attached on the chord member (4), so that the assistant crane can continuously climb along the chord members without the cooperation with the other hoisting equipment. According to the invention, the difficulty that a tower type truss can not be installed when the altitude hoisting equipment is unavailable can be solved, and a mass of installing cost can be saved, so that the tower type truss is applicable to the occasion without the altitude hoisting equipment, and the convenience degree for the distribution of engineering equipment can be greatly improved.

Description

technical field [0001] The invention relates to a truss structure and an installation method, in particular to a tower-type truss installation structure and an installation method without the cooperation of high-altitude lifting equipment. Background technique [0002] In water conservancy and hydropower construction, or other large-scale engineering construction, the application of tower truss is very common, for example: the supporting column in the conveyor system of climbing high-speed concrete belt conveyor, the height is usually 30m ~ 120m, and the section width is usually 2m ~ 10m, Such tower trusses are usually hoisted by truck cranes, crawler cranes or cable cranes with very high lifting heights during installation. However, in many cases, due to the limitation of traffic roads near the installation location, large-scale lifting equipment cannot reach the installation location, or there is no high-altitude lifting equipment available in and around the installation s...

AI Technical Summary

Problems solved by technology

[0009] The present invention designs a tower-type truss installation structure and installation method without high-altitude lifting equipment. (2) The hoisting device installed on the existing truss needs to provide additional support points outside the steel chimney tower; (3) The hoisting device installed on the existing truss does not have a slewing mechanism, so it cannot be realized Swivel action, e.g. for installation of tower trusses with a large section width, cannot cover all installation positions
