Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment for buildings, and particularly relates to a support system for demolishing support beams used in construction projects. Background Art

[0002] Currently, in many foundation pit projects, reinforced concrete internal support beams are used to support the retaining structure of the foundation pit to ensure the safety of the foundation pit during excavation and construction. When using a wire saw, saw blade, etc. to cut the reinforced concrete support beam into segments, generally, a support bracket (such as a steel pipe scaffold or a steel structure stool, etc.) needs to be set at the bottom of the support beam to support the cut concrete support beam, and then a steel wire rope is tied for hoisting, or a forklift is used to shovel and remove it. However, due to limited working space in a narrow site, tight construction period and other conditions, it is difficult to move conventional support components and it is difficult to adjust the support height, thus causing certain potential safety hazards in construction.

[0003] Referring to the publicly disclosed technical solutions, the technical solution with the publication number CN108612109B proposes a method for demolishing a concrete support beam without a bracket. This demolition method uses a diamond chain to first pass through the steel bars in the middle of the support beam in advance for use as the force for pre-lifting, and then performs cutting, so that only a crane is used without using a support component to support the support beam during cutting; the technical solution with the publication number CN112065095B proposes a device for crushing and demolishing a reinforced concrete column and its use method. After using a wrapping structure to wrap the column to be demolished, a multi-bit drill is used in cooperation with a moving mechanism to work simultaneously along the length direction of the column to perform rapid crushing and demolition of the concrete column; the technical solution with the publication number US20150040788A1 proposes a method for demolishing a concrete structure by using a mixture of chemical substances activated by an electronic / electrical system. The chemical mixture used can cause expansion damage within the concrete structure, thereby causing the target concrete object to crack and further decompose; and this method is different from the strong destructiveness of traditional blasting methods, and its destruction effect is relatively mild and no longer pollutes the environment.

[0004] All of the above technical solutions mention technical solutions for demolishing concrete buildings. However, there is no mention of a temporary support solution for the process of demolishing support beams that needs to be carried out in an organized manner on a large scale.

[0005] The foregoing discussion of the background art is only intended to facilitate the understanding of the present invention. This discussion does not recognize or admit that any of the materials mentioned is a part of common general knowledge. Summary of the Invention
