Method for non-vibration dismantling of concrete building structure

Abstract

The invention discloses a method for non-vibration dismantling of a concrete building structure. The dismantling method comprises the steps that 1, positioning and paying-off are conducted, and the sizes of holes needing to be cut and cutting lines needing to be cut are popped up through snapping; 2, hoisting holes are drilled, a chain hoist and components such as fixing components and a lifting hook are mounted; 3, pre-hoisting is conducted, one end of the chain hoist is connected with the lifting hook, and the other end of the chain hoist is pulled by the hand; 4, block drilling and cuttingare conducted along the cutting lines according to a cutting scheme plan; and 5, concrete blocks are moved in a hoisted mode, hoisting and transferring are conducted after cutting is completed, and floor cutting openings are plastered and rendered. Construction preparation comprising site preparation, mechanical equipment preparation, calculating of the weight of drilled and cut floors and mounting of an n-shaped frame support is further conducted before the step 1. The method has the advantages that in the dismantling process, normal operation and management activities of shops are ensured while construction is conducted, dust and vibration are avoided, and the influence on other structures is small.

Description

technical field [0001] The invention relates to a demolition method, in particular to a no-vibration concrete building structure demolition method. Background technique [0002] With the continuous advancement of my country's urban modernization, the demand for demolition of old houses, renovation and renovation of old houses is increasing. At present, the vast majority of buildings are built with concrete, and the commonly used methods in the process of demolishing the entire building are: mechanical demolition and blasting demolition. However, for old house renovation, house renovation, shop decoration, etc., it is often necessary to remove some walls, floors, or install conveyor elevators, etc. At this time, mechanical demolition and blasting demolition can no longer meet this demand. For the conventional direct cutting demolition, not only will the load be uneven during the cutting process, the structure will be deformed, the vibration will be large, cracks will appear,...

Problems solved by technology

However, for old house renovation, house renovation, shop decoration, etc., it is often necessary to remove some walls, floors or install conveyor elevators, etc. At this time, mechanical demolition and blasting demolition can no longer meet this demand.

For conventional direct cutting and demolition, not only will the load be uneven during the cutting process, the structure will be deformed, the vibration will be large, cracks will appear, and a lot of dust will be generated, which will not be able to operate normally for the store and affect the profit of the store
