Hollow column with support pillars and construction method thereof

Abstract

The invention discloses a hollow column with support pillars and a construction method thereof. The hollow column comprises a column body, support pillars, a cavity and protruding steel bars. The hollow column is prefabricated by the support pillars and the column body, the center of the column body is equipped with the cavity running through the upper and lower end faces of the column body, two ends of the column body are provided with the protruding steel bars that are staggered in length, the support pillars are disposed two opposite sides of the column body, support pillar steel bar framestructures are bound inside the support pillars, the support pillar steel bar frame structures and the column body steel bars are bound into a whole, the lengths of the protruding steel bars at the bottom of the column body do not exceed the bottom end faces of the support pillars, and the upper end face of the column body and the upper end faces of the support pillars are located at the same horizontal plane. During installation, only the protruding steel bars at the bottom of the column body need to be brought into fixed connection, pillar dies are disposed, and then pouring can be carried out. According to the invention, the support pillars in the hollow column play the role of supporting the column, additional arrangement of a column support is unnecessary, and the hollow column with support pillars plays a main supporting role for follow-up floor installation, and has the advantages of simplifying the construction method, improving the work efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a hollow column with a top column and a construction method thereof. technical background [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 prefabricated buildings, the columns are usually pre-embedded with grouting sleeves at the bottom, and are connected by grouting sleeves, so the connection quality is difficult to guarantee. At present, there are also prefabricated columns with outstretched steel bars at both ends, so that the column steel bars can be connected with existing steel bar connections, such as lap joints, welding and mechanical connections. The quality of the steel bar connections is safe and reliable, ensuring the quality of the building. Howev...

Problems solved by technology

However, when the column is installed, it is necessary to erect the column support and the combination mold at the bottom of the support column. The structure of the combination mold is complex, because the bottom of the column is suspended when the column is installed, so it has the disadvantages of complex column support erection, cumbersome construction, and low work efficiency.
