Prefabricated column connecting structure

Abstract

The invention provides a prefabricated column connecting structure, which comprises a prefabricated column, a foundation and a connecting piece, wherein a plurality of prefabricated column steel bars are evenly embedded in the prefabricated column; the upper surface of a first connecting plate is welded to the bottom parts of the prefabricated column steel bars; a plurality of first inserting feet are welded to the left end and the right end of the lower surface of the first connecting plate; a plurality of pre-embedded steel bars are evenly embedded in the foundation; a second connecting plate is embedded in the upper surface of the foundation; a plurality of second inserting feet are welded to the left end and the right end of the upper surface of the second connecting plate; an upper connecting groove is arranged on the upper surface of the connecting piece; a plurality of first inserting grooves are arranged on the bottom surface of the upper connecting groove; a lower connecting groove is arranged on the bottom surface of the connecting piece; a plurality of second inserting grooves are arranged on the top surface of the lower connecting groove; bolts are in threaded connection in the first threaded through holes; and a U-shaped bolt is inserted into each first through hole. Due to the fact that the connecting piece is matched with the prefabricated column and the foundation, the prefabricated column can be installed conveniently and rapidly, and the manufacturing cost is not high.

Description

technical field [0001] The invention relates to the technical field of building structures, and more specifically relates to a connection structure of prefabricated columns. Background technique [0002] Columns are elongated members used to support beams and trusses in buildings. In the engineering structure, the vertical rods that mainly bear the pressure and sometimes bear the bending moment are used to support beams, trusses, floors, etc. In traditional construction projects, the supporting columns are cast on site. But for prefabricated buildings, a large number of building parts are produced and processed by the workshop, and then assembled directly on the construction site, which greatly improves the construction speed and efficiency of the building. [0003] At present, the installation of prefabricated columns adopts the method of sleeve grouting to connect the column to the foundation and column to column. However, the connection method of sleeve grouting has high...
