Problems solved by technology

[0003] Existing demolition of building concrete generally adopts manual crushing or mechanical crushing. During the construction process, there are often problems such as long construction period, large labor input, low efficiency, large impact on the surrounding environment, and large amount of post-construction processing. The concrete structure has the disadvantages of large impact, and it is not safe and prone to accidents

Embodiment 1

[0031] The concrete structure static cutting construction method of the present invention mainly includes the steps of selection of construction equipment, division of cutting units, erection of supporting scaffolding, installation of hoisting auxiliary facilities, cutting construction, component hoisting, and site cleaning.

[0032] The specific construction method and operation points are as follows:

[0033] (1) Selection of construction equipment

[0034] Select suitable construction equipment according to the site environment. Taking the underground commercial cutting of a certain building as an example, the number of cutting layers is three, the cutting area of ​​a single layer is 1215 square meters, the size is 27 meters X 45 meters, and the bearing capacity of the roof structural plate is 20KN / m2. The thickness of the top layer is 180mm, the thickness of the first layer is 100mm, the thickness of the bottom layer is 350mm, the beam of the first layer is 300mm×800m...

Abstract

The invention discloses a concrete static force cutting dismantling construction method which mainly comprises the steps of construction equipment selection, cutting unit division, supporting scaffold erection, hoisting auxiliary facility installation, cutting construction, component hoisting and site cleaning. The concrete static force cutting dismantling construction method has the obvious advantages that the effect on the surrounding structures is small in the process of constructing, the constructing speed, the constructing precision and the safety are high, and components which are cut through the static force are convenient to clean. The concrete static force cutting dismantling construction method is suitable for dismantling various reinforced concrete members, and especially for dismantling the part structures with the high demand for dismantling and with the small effect on an original structure. Time and production cost are greatly saved, and the construction period is effectively shortened.

Description

technical field [0001] The invention belongs to the field of construction engineering, and particularly relates to a concrete static cutting and demolition construction method, which has little influence on surrounding structures, fast construction speed, high construction precision, high safety, and easy cleaning of components after static cutting, and can be applied to various It is suitable for the demolition of reinforced concrete components, especially suitable for the demolition construction of some structures that have high requirements for demolition and have little impact on the original structure. Background technique [0002] At present, urban construction is changing with each passing day, and old buildings often need to be demolished. Or during the construction of the construction project, due to the change of the functional design of some projects, it is necessary to demolish the part of the concrete structure project that has been completed. Since the demolit...
