Low-noise house alteration beam and slab dismantling method

Abstract

The invention provides a low-noise house alteration beam and slab dismantling method. By erecting a reliable steel pipe scaffold unloading platform under beams and slabs to be dismantled, abutting against the platform with wooden wedge blocks, effective unloading is achieved, in-site construction load transfer is ensured, and adverse disturbance is not produced to surrounding retained members; secondly, a cutting machine is utilized to execute high-speed motion under the driving of a motor, executes high-speed steel bar and concrete grinding and cutting along designated tracks and routes and accordingly completes vibration-free accurate cutting of reinforced concrete beam plates; finally, to-be-cut slab upper-layer main beams are used as hoisting support points, simple devices such as a chain hoist are adopted to hoist cut concrete blocks from an original structure to a bottom layer and then transport the blocks to designated places to complete concrete block crushing and solve the technical problem that existing house alteration beam and slab dismantling operation is low in efficiency, long in construction period, large in dust amount, high in noise and disturbs residents in a downtown area due to construction.

Description

Technical field [0001] The invention relates to the technical field of house reconstruction, and more specifically, to a low-noise demolition method of beams and slabs for house reconstruction. Background technique [0002] With the rapid development of urban construction and the continuous improvement of urban functional blocks, the original design functions of old houses cannot meet people's new use requirements. Many old buildings in downtown areas need to be added or renovated. When the original building and the cast-in-situ roof structure cannot meet the new bearing capacity requirements, or to increase the indoor clearance of the house, increase the indoor elevator (or the stair shift), often the original house concrete building, the roof cast-in-place beam slab tear down. The traditional demolition of concrete structures is gradually removed by pneumatic picks. The construction vibration will cause dynamic stress of the building structure, adversely disturb the original s...
