The invention discloses a steel pipe column bearing table girder connection construction method. The method comprises the following steps of: paving a bottom plate cushioning layer; mounting a steel pipe column bottom plate in a bearing table foundation pit; building a bearing table ring girder reinforcing steel bar processing frame around the bearing table foundation pit; binding bearing table ring girder reinforcing steel bars on the bearing table ring girder reinforcing steel bar processing frame; setting a foundation beam supporting frame between a ring girder and a main girder connection; binding foundation girder reinforcing steel bars on a foundation girder supporting frame; hoisting a steel pipe column into each bearing table ring girder reinforcing steel bar and welding the steel pipe column on the steel pipe column bottom plate; and unloading the bearing table ring girder reinforcing steel bars and the foundation girder reinforcing steel bars as a whole. Due to the adoption of the steel pipe column bearing table girder connection construction method, the steel pipe column bearing table girder connection construction method which is convenient for construction is realized. The method has the advantages of convenience and quickness in construction, high construction speed, high quality and high stability.
Description
technical field [0001] The invention relates to a construction method, in particular to a construction method for a steel pipe column bearing platform beam joint. Background technique [0002] The steel pipe column ring beam joint is a new type of steel pipe concrete beam column joint that has been widely used in recent years. The design of this ring beam joint has gradually matured. Positive effect. However, due to the large diameter and height of the cap ring beam, the dense reinforcement of the beam-column joints, the large cross-sectional size and high height of the beam, the interspersed construction of the steel pipe column and the cap ring beam, and the construction of the foundation beam reinforcement are difficult, and the construction progress is slow. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a steel pipe column cap beam joint construction method, which realizes a convenient ...
