Referring to fig. 1 to 6, the present invention provides an environment-friendly demolition method for a high-rise building, including the steps of:
a. the demolition apparatus 3 is hoisted to the top of the high-rise building 1 (i.e., the deck at the top of the N floors of the high-rise building) via the core barrel or elevator shaft of the high-rise building 1. The breaking device 3 comprises a breaking hammer, a hydraulic clamp, a hydraulic rope saw and an excavator.
b. A dust cover 2 is provided, an acoustic panel 20 is laid on the outer side of the dust cover 2, a locking accessory 21 and a height-adjustable support column 22 are installed in the dust cover 2, and the dust cover 2 is covered on the top of a high-rise building 1.
In this embodiment, the support column 22 includes two standard joints 221 and a hydraulic jack 222 connected between the two standard joints 221.
The number of the locking accessories 21 is multiple, the locking accessories 21 are arranged on the inner side of the protective cover in two layers, and the distance between the two layers of the locking accessories 21 is adaptive to the floor height of the high-rise building 1.
The height of the dust cap 2 is three times the layer height. As shown in fig. 1, the dust cover covers N floors, N-1 floor and a space above the N floors of the high-rise building.
c. The lock attachment 21 is mounted to a structural beam at the top of the high-rise building 1 to be locked thereto.
d. The multi-layer floor bearing plate chiseling through the top of the high-rise building 1 forms a socket hole, and the support column 22 is arranged in the socket hole and supports against the floor bearing plate corresponding to the bottom of the socket hole 10.
Specifically, the floor bearing plates on the tops of the N layers and the N-1 layers are chiseled for the first time to form the socket holes. The standard knot at the bottom of the support column is mounted to the floor deck at the bottom of the N-1 floor.
e. The floor structure where the demolition device 3 is located is demolished inside the dust cover 2 by the demolition device 3, and the construction waste generated by the demolition is transported to the bottom floor of the high-rise building 1 via the core barrel or the elevator shaft.
When the step of removing the floor structure where the breaking device 3 is located is performed, the horizontal beam and the plate structure of the floor structure are removed first, and then the shear wall and the column of the floor structure are removed.
f. After the floor structure is removed, the locking fittings 21 are separated from the structural beams, and the supporting columns 22 are contracted to lower the height, so that the dust cover 2 is placed on the top of the removed high-rise building 1.
g. And repeating the steps c-f to demolish the high-rise building 1 layer by layer downwards.
The environment-friendly demolition method for the high-rise building is suitable for the building which is about to be demolished after reaching the upper limit of the design service life or being additionally planned, the high-rise cross sections of the building are consistent or the appearance is relatively regular, and the higher the floor is, the more economical the building is; the method is suitable for buildings in downtown areas with compact building spacing and incapability of blasting demolition, and has the advantages of low demolition construction noise, less dust, full sealing, small visual impact, controllable speed, environmental protection and safety.
When the building is dismantled, in order to achieve the sound-proof and dust-proof effects, the parts of the dust-proof cover are hoisted to the roof of a high-rise building through the core barrel or the elevator shaft, and the dust-proof cover is assembled on the roof to form a closed sound-proof dust-proof cover with 3 floors of height. The dust cover uses the sound absorption and insulation board at the periphery and upper part of the dismantling operation surface of the roof of the high-rise building for sound insulation and dust prevention.
The steel frame shed structure of the dust cover is assembled according to design drawings, the sound absorption plate is installed on the steel frame shed structure, the lock accessory is installed on the inner side of the steel frame shed structure, and the supporting column is installed on the inner side of the top of the steel frame shed structure. The bottom of the support column is temporarily fixed with a structural beam plate of a high-rise building. In this embodiment, the lock attachment is a peg key. One end of the stud connecting key is fixedly connected to the steel frame shed structure, and the other end of the stud connecting key is anchored in a structural beam of the high-rise building.
According to the plane size of a high-rise building, the supporting columns of the hydraulic jacks are reasonably arranged, the columns or the shear walls of the original structure are replaced by the supporting columns, the effect of load conversion is achieved, and the dust cover is supported.
And then, the high-rise building is dismantled layer by layer from the top layer to the bottom layer of the high-rise building, the horizontal beam and the plate structure are dismantled in the same layer, and then the shear wall and the column are dismantled until the first layer is reached. The supporting column has small holding load, low energy consumption, safety and reliability.
When the machine is dismantled, the breaking equipment (such as a mechanical breaking hammer, a hydraulic clamp, a hydraulic rope saw, an excavator and the like) needs to be vertically transported to a breaking operation layer, and after the operation is completed, the machine is transported to the next layer through a hydraulic jacking platform in a high-rise building.
The function of lowering the dust cover layer by layer in the vertical direction by controlling the height of the supporting column in a climbing and contracting mode is achieved. Calculating the supporting counter force required by the hydraulic jack of the supporting column, determining the required length of the supporting column and the quantity of the supporting columns penetrating through the floor bearing plates, and performing temporary embedding work with each floor bearing plate and each beam. The hydraulic jacks of each supporting column are controlled in a unified mode, and the effect of synchronously reducing the dust cover is achieved.
On the other hand, the broken construction waste is classified and loaded into a closed box by the breaking equipment, the original elevator shaft or core barrel in the high-rise building is used as a waste channel for dismantling the building, and the construction waste is slowly transported to the bottom layer through equipment such as chain block and the like and then is transported outside.
The environment-friendly demolition method for the high-rise building utilizes an elevator shaft or a core barrel of the high-rise building as a transportation channel for hoisting demolition equipment and demolition generated building garbage, dust and spatters generated by demolition of the high-rise building are gathered in a dust cover through the dust cover during demolition, the environment is kept clean, demolition safety of the high-rise building is improved, the dust cover can be lowered through a supporting column with adjustable height and is always covered on the top of the high-rise building, and demolition of each floor of the high-rise building is ensured to be always carried out under protection of the dust cover.
The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be appreciated by a person skilled in the art that the scope of the invention as referred to in the present application is not limited to the embodiments with a specific combination of the above-mentioned features, but also covers other embodiments with any combination of the above-mentioned features or their equivalents without departing from the inventive concept. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
