Abstract

The invention relates to a load-bearing floor steel beam section diminishing method according to design change. Due to the fact the sections can only be diminished by mounting steel column supports below steel beams in conventional construction, the flowing problems that floor load cannot be eliminated, and the steel column supports cannot be set at high positions, are high in construction cost and high in labor intensity of workers during construction, and has potential safety hazard cannot be avoided. The method has the advantages that construction is safe and economical, the floor steel beam with the diminished beam section can reach the design requirement of reliable use, the mechanical property of the self stress of the floor steel beam is utilized, a cut is formed at the design change position of a crossbeam, the mounting connection of a floor steel beam web with a bottom flange is processed section by section, the newly mounted lower flange plates of each section is welded with the original floor steel beam web so as to gradually form a new beam integrity, the redundant original floor web and the bottom flanges are cut, and corrosion resistance processing is performed.

Description

[0001] Technical field:

[0002] The technology of the invention relates to the field of green and environment-friendly buildings, and specifically refers to a construction treatment technology for reducing the section of a steel beam on a floor according to a design change under a load condition.

[0003] Background technique:

[0004] Many current high-rise, super high-rise buildings and heavy-duty steel structure industrial buildings use steel frame systems. During the construction process, it is often necessary to change the section of some installed floor steel girders due to design errors or owner requirements. For some floor steel beams whose sections need to be reduced, when the design changes are carried out under the conditions of various loads, according to the conventional construction technology, the steel column support must be installed under the steel beams before the section can be reduced. Therefore, in The following problems often exist during the constructi...
