Problems solved by technology

[0003] However, such a dismantling method will consume a lot of time and manpower due to the need to build a large-area support frame before dismantling.
In addition, the support frame and other facilities fill the entire underground space, which also greatly restricts the construction personnel's activity space, making it difficult to operate and dismantle

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the drawings.

[0022] Such as Figure 1 to Figure 6 The shown method for dismantling a large concrete structure without pre-support, the large concrete structure comprising a cover plate 1, a beam used to support the cover plate 1, a supporting column 3 used to support the beam 2, includes the following steps:

[0023] a. Select the cover plate 1 that needs to be removed, and cut the selected cover plate 1 obliquely along the thickness direction of the cover plate 1. The oblique cutting surface 13 of the cover plate formed by the oblique cutting cuts the top surface of the cover plate 1 Separate the top surface 12 of the cover plate, the oblique cutting surface 13 of the cover plate separates the bottom surface of the cover plate 1 from the bottom bottom surface 11 of the cover plate, and the area of ​​the top surface 12 of the cover plate is larger than the area of ​​the bottom bottom surface 11 of t...

Abstract

The invention relates to the field of concrete structure demolition, in particular to a large concrete structural body pre-supporting-free demolition method and aims at providing a large concrete structural body pre-supporting-free demolition method which is adopted to cut, break down and demolish concrete buildings without pre-installation of a large concrete demolition supporting frame. In the large concrete structural body pre-supporting-free demolition method, a large concrete structural body comprises a cover plate, a cross beam for supporting the cover plate and a supporting column for supporting the cross beam. The large concrete structural body pre-supporting-free demolition method comprises the following steps of (a) selecting the cover plate required to be demolished, performing oblique cutting on the cover plate in the cover plate thickness direction and hoisting the cover plate through a hoisting device; (b) selecting the cross beam required to be demolished and performing oblique cutting on the cross beam in the cross beam thickness direction and hoisting the cross beam through the hoisting device; (c) demolishing the supporting column. The large concrete structural body pre-supporting-free demolition method is easy to implement, practical and effective and especially suitable for the large concrete structure demolition construction.

Description

Technical field [0001] The invention relates to the field of methods for dismantling concrete structures, in particular to a method for dismantling large concrete structures without pre-support. Background technique [0002] For concrete buildings such as factory buildings, when they need to be demolished, the current technical method is to first build a support frame that can support the concrete structure's cover plate, beams and other suspended components, and then cut the cover plate, beams, etc. And demolished. Due to the existence of the support frame, the cover plates, beams and other components that have lost the support can be supported by the support frame, and will not directly fall to the ground, so that the removal work can be carried out in a safer and orderly manner. [0003] However, this dismantling method is precisely due to the need to build a large area of ​​support frame before dismantling, which consumes a lot of time and manpower. In addition, supporting fr...
