Problems solved by technology

When the foundation pit is affected by various conditions and becomes unstable and damaged, the surrounding protection piles of the foundation pit and the steel pipe cross braces will generate tension, and the steel pipe cross braces are mainly compression structures. Under tension conditions, the cross braces inside the foundation pit are easily In the event of a fall, the weight of the steel pipe cross brace in the foundation pit is relatively large, generally up to 2 to 3 tons. If it falls suddenly, it will kill and injure the workers at the bottom of the foundation pit, damage the machinery and equipment, and cause huge loss of life and property and bad social influence

Abstract

The invention relates to a foundation pit steel pipe cross brace anti-falling and early warning device. The foundation pit steel pipe cross brace anti-falling and early warning device comprises a tension meter, two connecting end parts, a connecting chain, end part chains, a first connecting plate, a second connecting plate, a tension display and an alarm device, the two connecting end parts are correspondingly mounted at two ends of the tension meter, any one connecting end part is connected with the connecting chain, the tail end of the connecting chain and the other connecting end of the connecting chain are sleeved with end chains, any one end chain is fixedly connected with a steel support through the first connecting plate, and the other end chain is fixedly connected with a foundation pit supporting pile through the second connecting plate. The device can well prevent the steel pipe cross brace from being separated from the foundation pit supporting pile and falling off due to foundation pit displacement overrun or instability, life safety of operators at the bottom of the foundation pit and safety of machines and equipment are effectively guaranteed, and meanwhile early warning can be provided for safe use of the foundation pit. The method has good market application potential and is worthy of popularization and production.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-falling and early warning device for steel pipe cross braces in foundation pits. Background technique [0002] With the continuous development and construction of urban underground space, the construction of urban subways, comprehensive pipe corridors, and basements of high-rise buildings is inseparable from the excavation of foundation pits. In engineering, in order to ensure the safety of foundation pit support structures, a common The method is to set more cross braces in the foundation pit, and steel pipe cross braces are a common support method. However, the traditional foundation pit steel pipe cross braces are usually directly welded to the foundation pit supporting piles through purlins. When the foundation pit is affected by various conditions and becomes unstable and damaged, the surrounding protection piles of the foundation pit and the steel pip...
