Problems solved by technology

However, the prefabricated technology currently used has been limited to buildings above the ground. There is no mature technology for the prefabricated foundation, especially the prefabricated foundation used with special-shaped steel pipe columns. The foundation part seriously restricts the construction period of the prefabricated structure.

Abstract

The invention discloses a fabricated structure matched with a special-shaped steel pipe column and a construction method of the fabricated structure. A second prefabricated plate is fixedly arranged above a first prefabricated plate, and a mortise matched with the special-shaped steel pipe column is formed in the side wall of the second prefabricated plate; tenons matched with the mortise are arranged at the two ends of a concrete foundation beam correspondingly, and the tenons are clamped into the mortise to enable the concrete foundation beam and the second prefabricated plate to be in mortise-tenon connection; a plurality of bolt rods are pre-buried in the upper portion of the second prefabricated plate, and an outer reinforcing ring plate is welded to the lower end of the special-shaped steel pipe column and used for pressing the tenons on the concrete foundation beam; and a plurality of bolt holes matched with the bolt rods are formed in the outer reinforcing ring plate, and the special-shaped steel pipe column is in bolted connection with a prefabricated concrete foundation through the outer reinforcing ring plate. According to the fabricated structure matched with the special-shaped steel pipe column and the construction method of the fabricated structure, mounting can be completed in a multi-storey house in one day, the bottleneck problem of the construction period of a low-storey house is solved, foundation members are prefabricated in a factory, formworks are reused and adopted in large-scale construction, a large amount of labor is saved, and the construction cost can be lower than that of a traditional foundation.

Description

technical field [0001] The invention relates to an assembled structure adapted to a special-shaped steel pipe column and a construction method thereof, belonging to the field of assembled independent foundations. Background technique [0002] In recent years, the rapid development of my country's prefabricated buildings has driven the growth of steel structures. According to incomplete statistics, more than 30 provinces and cities across the country have issued special guidance and related supporting measures for prefabricated buildings. There are clear requirements for the development of prefabricated buildings. However, the prefabricated technology currently used has been limited to buildings above the ground. There is no mature technology for the prefabricated foundation, especially the prefabricated foundation used with special-shaped steel pipe columns. The foundation part seriously restricts the construction period of the prefabricated structure. In view of the above-m...
