I-shaped steel welding platform and application method thereof

Abstract

The invention provides an I-shaped steel welding platform and an application method thereof and belongs to the field of urban mass transit (interurban railway) open cut station foundation pit supportunderground continuous wall construction. The I-shaped steel welding platform comprises a platform body. Multiple web plate support brackets are arranged on the platform body in the length direction.The width of each web plate support bracket is the same as that of a middle web plate of corresponding I-shaped steel. The upper end faces of the multiple web plate support brackets are flush with oneanother. The two opposite sides of the multiple web plate support brackets are each of a plat plate structure perpendicular to the platform body and aligned with each other. Oblique plane limiting plates are fixed to the positions, at the two opposite sides of the web plate support brackets, of the platform body correspondingly. The inner sides of the oblique plane limiting plates are provided with oblique plane structures which are arranged toward the outer side from bottom to top in an inclined manner. The I-shaped steel welding platform and the application method thereof aim at improving machining efficiency and quality of underground continuous wall reinforcement cage I-shaped steel joints.

Description

technical field [0001] The invention relates to an I-beam welding platform and a method for using the same, belonging to the field of construction of underground diaphragm walls for foundation pit enclosure protection of open excavation stations of urban rail transit (intercity railway). Background technique [0002] At present, the foundation pit enclosure structure of open excavation stations is mainly based on underground diaphragm walls. The joints between the reinforcement cages of underground diaphragm walls use I-shaped steel joints. Take Science Center Station as an example, its enclosure structure adopts 1200mm thick underground diaphragm wall, the standard width of the diaphragm walls in both stations is 6 meters, the connection between the underground diaphragm walls is designed with I-beam connection, the existing underground diaphragm wall reinforcement The processing efficiency of the cage I-beam joint is low, the processing quality is poor, the flatness is poo...
