Abstract

The invention discloses an irregular-shaped leg column support installation and construction method. The method comprises the following steps that (1) multiple layers of bottom load-bearing rebars are installed on a bearing platform bed course at the top end of a pile foundation of a bearing platform, meanwhile, multiple sets of supporting piers are installed on the bearing platform bed course, and the supporting piers are welded to the intersections of the bottom load-bearing rebars; (2) a bearing platform door type stiff main framework is fixed to each set of supporting piers in the vertical direction, and then the lower portions and the middle portions of the adjacent main frameworks are fixedly connected through bottom-layer connecting beams and the middle load-bearing rebars, wherein the bottom-layer connecting beams and the middle load-bearing rebars are arranged in the horizontal direction; (3) concrete is poured in the spacing between the bearing platform bed course and the upper portions of the middle load-bearing rebars; (4) the tops of the adjacent main frameworks are fixedly connected through top-layer connecting beams arranged in the horizontal direction; (5) multiple layers of top load-bearing rebars are fixedly connected to the top-layer connecting beams; (6) supports are installed on the main frameworks. By the adoption of the method, the whole stress system having enough bearing capacity is formed.

Description

technical field [0001] The invention relates to a support construction method, in particular to a special-shaped leg post support installation construction method. Background technique [0002] The special-shaped leg column used to support the shaftless large-tonnage ferris wheel must have sufficient bearing capacity and a stable landing support point. The Chinese patent with the application number CN201310583286.6 discloses a "double-row four-slant-leg steel structure portal pier", which specifically relates to a double-row four-slant-leg steel structure portal pier. It includes block No. 0 and a steel cover beam. The two ends of the bottom of the steel cover beam are respectively connected with a left row of pier columns and a right row of pier columns. Right cap, the left row of pier columns includes the first left pier column and the second left pier column, the tops of the first left pier column and the second left pier column intersect at the bottom end of the steel c...
