Application of positioning rib in large storage tank bearing platform ring wall foundation

Abstract

The invention provides an application of a positioning rib in a large storage tank bearing platform ring wall foundation. By means of the application, the flatness of the surface of a formed ring wall is improved, trimming of the surface of the ring wall is more convenient, efficient and rapid, the construction period is shortened, and the construction cost is reduced. The positioning rib is applied in the large storage tank bearing platform ring wall foundation, the elevation of the positioning rib and the elevation of the formed ring wall foundation are consistent, the positioning rib is an annular steel bar (1) arranged in the horizontal direction, the bottom end of the annular steel bar (1) is welded to the top ends of vertical ribs (2) arranged vertically, and the distance between every two adjacent vertical ribs (2) is 900-1100 mm. The bottom end of each vertical rib (2) is welded to a main rib (3) arranged in the horizontal direction, and the main ribs (3) are welded and fixed to the top of a storage tank bearing platform ring wall foundation steel bar net frame (4).

Description

technical field [0001] The invention relates to the inventive application of a positioning rib in the ring wall foundation of a large storage tank cap. Background technique [0002] At present, in the construction of the ring wall of storage tanks in large-scale petrochemical projects, the method of elevation measurement and manual leveling is mostly used to control the surface smoothness of the ring wall. Since there is no fixed reference for the repair personnel to refer to, it is relatively difficult to repair the ring wall surface. Difficulties, resulting in the surface roughness of the ring wall after forming is seriously exceeded, and the subsequent re-moulding is difficult, resulting in a large waste of construction period and construction cost. Contents of the invention [0003] The purpose of the present invention is to provide a positioning bar that can improve the flatness of the ring wall surface after forming, make the surface repair of the ring wall more conv...
