Foundation structure of transformer substation power distribution unit storied building

Abstract

The invention discloses a foundation structure of a transformer substation power distribution unit storied building. The foundation structure comprises multiple first reinforcing steel bars, a raft poured through concrete and a foot stall arranged on the raft. The foot stall comprises a cross steel frame, a cross fixed base, a box column, and a column base reinforcing pier. The cross steel frame is embedded in the raft in a flat laying manner, the cross steel frame is fixedly welded with the adjacent first reinforcing steel bars in the raft, the cross fixed base is welded and fixed to the center area of the top face of the cross steel frame, the box column is arranged vertically and fixed to the center area of the top face of the cross steel frame, the bottom edge of the box column is provided with a clamping groove matched with the cross fixed base, the interior of the box column is a concrete filling area, and multiple toggle pins are welded to the periphery face of the box column; the column base reinforcing pier is formed through pouring of multiple second reinforcing steel bars and concrete and wraps the bottom of the box column, and the second reinforcing steel bars comprisemultiple longitudinal ribs arranged on the periphery of the box column and multiple stirrups connected with the multiple longitudinal ribs.

Description

technical field [0001] The invention relates to the construction field, in particular to a basic structure of a power distribution device building of a substation. Background technique [0002] In recent years, with the formation of my country's intensive urbanization development strategy, various industrial and civil buildings have been greatly developed. In order to make full use of the performance of materials, people have introduced a composite structure system of steel pipe concrete on the basis of the original reinforced concrete structure system. The confinement effect puts the concrete in a state of three-way stress, so that the strength of the concrete is improved, the brittleness is reduced, and the plasticity and toughness are greatly improved; at the same time, due to the deformation of the concrete, the steel pipe is also in a complex stress state, and the steel pipe is strengthened. wall stability. [0003] At present, there are many studies on the beam-colum...

Problems solved by technology

[0003] At present, there are many studies on the beam-column joints of the concrete-filled steel tube superstructure, but the column-foot form of the steel structure is still used for the foundation column-foot joints, and there is no design of the column-foot foundation according to the characteristics of the steel-filled steel tube concrete structure.
