Abstract

The invention provides a concrete support beam no-support disassembly method. The method comprises the following steps: (a) a cutting scheme is actually determined according to the scene; and a cutting position is marked on a concrete support beam needing to be cut according to the cutting scheme; (b) concrete at the upper corner of the cutting position of the support beam is drilled off, so thata main rib at the upper corner of the support beam is exposed; and a through groove for enabling a diamond chain to penetrate through is drilled in the lower part of the main rib; (c) the diamond chain penetrates through the groove to wind the bottom of the support beam by one lap; the closed diamond chain is connected; and then, the segmented cutting is performed on the support beam through the diamond chain; and (d) after the segmented cutting work of the support beam is finished, each section of the support beam is lifted through a crane; and the main rib connected to the upper part of thesupport beam is cut off, so that each section of the support beam is thoroughly cut off, and is lifted for transportation one by one.

Description

Technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for dismantling a concrete support beam without a bracket. Background technique [0002] At present, in many foundation pit projects, reinforced concrete inner support beams are used to withstand the retaining structure of the foundation pit to ensure the safety of the foundation pit during excavation and construction. When the reinforced concrete support beam is cut and removed in sections by wire saws, saw blades, etc., it is generally necessary to set a support bracket at the bottom of the support beam (the bottom bracket is usually a steel pipe scaffold, or a steel structure horse stool, etc.). The lower concrete support beam supports it, and then binds the wire rope for lifting, or uses a forklift to remove it. However, due to the limited working surface of the site and the tight construction period, the erection and removal of supporting brackets and other fa...
