High-support formwork system stability detection early warning method and device

Abstract

The invention is suitable for the technical field of building construction safety detection, and provides a high-support formwork system stability detection early warning method and device, and the method comprises the following steps: applying a gradually increased horizontal tension load to a rod node of a high-support formwork frame body; releasing the horizontal tension load when the horizontal tension load reaches a first threshold value; collecting vibration mode information of the high-support formwork body after the horizontal tension load is released, and obtaining a vibration displacement frequency curve of the high-support formwork body; judging whether the amplitude of the vibration displacement frequency curve of the high-support formwork body exceeds an amplitude limit value or not, and outputting a detection result; if yes, issuing an early warning; and if not, continuing to collect the vibration mode information of the high-support formwork body after the horizontal tension load is released. According to the embodiment, whether the overall stability of the high-support formwork body is qualified or not can be detected by monitoring the real-time vibration mode of the high-support formwork body, the safety condition of the high-support formwork system is mastered, and the detection range is wide.

Description

technical field [0001] The invention belongs to the technical field of building construction safety detection, in particular to a method and device for detection and early warning of the stability of a high formwork system. Background technique [0002] With the rapid development of urban modernization, large-span structures and super-high building structures in cities are gradually increasing, and high-formwork systems are more and more widely used in engineering fields. The tall formwork support system is referred to as the high formwork system for short, which refers to the formwork support system with a concrete member formwork support system with a height of 8m and above, or a formwork support system with a span of 18m and above. High formwork engineering has the characteristics of complexity, high risk, and sudden accidents. The main reasons for the collapse safety accident of the high-support formwork are various, among which the erection of the high-support formwork...
