Example Embodiment

[0040] The theoretical basis and implementation method of the present invention are as follows:

[0041]1. Safety requirements for mechanical demolition of buildings (structures)

[0042] 1. For the construction of mechanical demolition of buildings (structures), mechanical equipment is used to demolish the beams, walls and columns in an orderly manner from top to bottom. After the concrete on the floor is demolished, hydraulic shears are used to cut the steel bars. According to construction experience and on-site observation, this kind of mechanical demolition method, in the construction process, the column structure is relatively safe, while the beam in the demolition process is in cantilever state, the safety factor is low, so the construction (structure) mechanical demolition process The focus of dynamic safety monitoring is beam stability.

[0043] 2 In the process of mechanical demolition of buildings (structures), the safety of the part of the building or the remaining...

Abstract

The invention discloses a dynamic safety-monitoring and alarming method in building (structure) mechanical-dismantling process. The method comprises the following steps of: acquiring the opening and closing-quantity signal of a crack group through displacement sensors installed at both sides of the crack group; and transmitting the acquired opening and closing-quantity signal of the crack group to a resistance strain meter for processing through a shielding wire, converting the opening and closing-quantity signal value of the crack group into the bending-deformation value of a column, the suspended-end sinking value of a cantilever beam or the mid-span sinking values of a simply-supported beam and a continuous beam, and connecting the resistance strain meter with one or more alarming devices. When the signal at some point processed by the strain meter exceeds the allowable value (also called as an alarming value), alarming signals are immediately sent out to the monitored point and involved dangerous points. Through the system and method, the technical problems of lagging safety-monitoring method, passive safety-assuring measures, poor safety-assuring effect and the like existing in traditional building mechanical-dismantling working can be solved.

Description

technical field [0001] The invention belongs to the technical field of construction industry engineering, in particular to the engineering technology of dismantling buildings (structures) in the construction industry. Background technique [0002] With the progress of industry and the development of society, the old urban area of ​​the city needs to be demolished or rebuilt, and factories or other construction (structure) facilities need to be demolished. The demolition methods of buildings (structures) can be divided into two types: blasting demolition and non-blasting demolition. Non-blasting demolition includes mechanical demolition and manual demolition. Although manual demolition has low technical requirements, low demolition cost, and is also conducive to the recycling of old materials, it is a backward demolition method with poor safety and low efficiency. Mechanical demolition is the use of special or general-purpose mechanical equipment to directly disintegrate or...
