Embodiment Construction
[0030] The application will be described in further detail below in conjunction with the accompanying drawings.
[0031] The embodiment of the present application discloses a construction method for dismantling a high-rise cast-in-place concrete building, which includes the following steps:
[0032] S1. Build a support frame 1 fixed around the high-rise concrete building above the middle part of the high-rise concrete building;
[0033] S2. Install the construction workbench 2 around the top of the high-rise concrete building, the construction workbench 2 is lifted and connected to the support frame 1, and as the demolition of the floor is completed, the construction workbench 2 will drop to the next floor;
[0034] S3. A vertical transportation machine for high-rise construction is installed on the opposite side walls of the high-rise concrete building at the corresponding positions of the support frame 1 and the construction workbench 2; the small concrete cutting machine is...

The invention relates to a demolition construction method for a high-rise cast-in-place concrete building. The demolition construction method comprises the steps that S1, a supporting frame is fixedly built above the middle of the high-rise concrete building; S2, a construction workbench connected to the supporting frame in a lifting mode is installed; S3, constructors use a small concrete cutting machine which is conveyed to the floor needing to be dismantled through a high-rise building construction vertical conveying machine to conduct cutting and dismantling, and final cutting is conducted on the construction workbench; S4, when construction is conducted to the supporting frame, the concrete building is hit by a crane for hanging steel balls for second-step dismantling; and S5, when the demolition height is reduced to 4-6 layers, third-step demolition is conducted from the bottom of the concrete building, the concrete building is subjected to weightlessness and overall collapse, and demolition is completed. In the first step, a layer-by-layer cutting and dismantling mode is adopted, in the second step, a steel ball impact dismantling mode is adopted, in the third step, dismantling is conducted from the bottom to promote collapse of the building, different dismantling modes are adopted for different heights, and the construction efficiency is higher while safety and reasonability are achieved.
Description
technical field [0001] The present application relates to the technical field of construction engineering, in particular to a method for demolishing a high-rise cast-in-place concrete building. Background technique [0002] At present, the vast majority of buildings are built with concrete. With the continuous advancement of urban modernization in my country, the demand for demolition of old houses, renovation and renovation of old houses is increasing; the commonly used method in the process of demolition of high-rise concrete buildings There are three types of demolition: mechanical demolition, blasting demolition and manual demolition. [0003] However, the demolition process of high-rise concrete buildings is highly dangerous, and none of these three forms is well suited for the demolition of high-rise concrete buildings. Therefore, the applicant believes that the existing construction methods still need to be improved. Contents of the invention [0004] In order to be...
