Early warning system for out-of-plane instability in sliding construction of inverted triangular truss type roof

Abstract

The invention relates to the field of installation or transportation of large-scale buildings, in particular to an early warning system for out-of-plane instability in sliding construction of an inverted triangular truss type roof. The early warning system is characterized by comprising a load adjustment subsystem (1), a slip unit lateral instability identification and stabilization subsystem (2) and a computer acquisition control subsystem (3). According to the early warning system, through the combined action of the load adjusting subsystem (1), the sliding unit lateral instability identification and stabilization subsystem (2) and the computer acquisition control subsystem (3), lateral instability of a sliding unit in the sliding process is effectively avoided, synchronous deviation correction in the sliding process is achieved, and smooth implementation of a sliding construction scheme is guaranteed; and the system has the biggest characteristic that the problem of lateral instability in the sliding process of the large-span inverted triangular truss type roof sliding unit is solved on the premise that the structural form of the sliding unit is not specially treated.

Description

technical field [0001] The invention relates to the field of installation or transportation of large-scale construction, in particular to an early warning system for out-of-plane instability in the sliding construction of an inverted triangular truss type roof. Background technique [0002] The hydraulic synchronous sliding technology uses hydraulic crawlers as the main driving equipment and uses computer control to adjust the overall sliding construction technology of hydraulic pressure. It is mainly used in the overall construction field of long-span steel roof structures. Usually, the sliding track is along the axis of the roof support, and a high-altitude assembly platform is set at one end of the roof. After assembling a sliding unit, slide it to the designated position, and then proceed to the assembly of the next sliding unit and slippage, construction in sequence, accumulative slippage to the design position successively. During the sliding process, the sliding tra...

AI Technical Summary

Problems solved by technology

If the construction period is tight, there are intersecting operations between civil construction and steel roof construction, and the construction site cannot meet the needs of scaffolding and large-scale hoisting machinery, hydraulic synchronous sliding construction is still a better solution

When this type of structure adopts the traditional hydraulic synchronous sliding construction method, there is a major technical problem: after the first sliding unit is assembled on the high-altitude assembly platform, during the process of sliding it into place, because the sliding unit is an inverted triangle, It is difficult to effectively guarantee the out-of-plane stability. During the sliding process of the first sliding unit, how to ensure the out-of-plane stability of the sliding unit is also a technical problem different from the conventional structure.
