Problems solved by technology

[0002] In the large-span iron tower, the load borne by the iron tower is relatively large. The main material of the steel pipe concrete is used at the bottom of the whole tower. Due to the force requirements, the diameter of the steel pipe is getting larger and larger. However, due to the limitation of the process and equipment, the thickness of the steel pipe can be rolled. Due to certain limitations, there may be a problem that the diameter-thickness ratio of large-diameter steel pipes exceeds the limit

Abstract

The invention relates to a power transmission tower and a power transmission tower supporting pillar. The power transmission tower comprises a tower body which is vertically arranged, and cross arms horizontally arranged on the top of the tower body. A supporting pillar is lengthways arranged at the bottom of the tower body. The supporting pillar comprises adhesives which are arranged radially from inside to outside, a reinforcing frame and an outer layer pipe. Mortar is arranged between the outer wall of the reinforcing frame and the inner wall of the outer layer pipe. The power transmissiontower supporting pillar combines the stress characteristics of the two materials, gives full play to the characteristic of a steel and concrete composite structure, and has the high pressure bearing capacity; and the capacity of the reinforcing frame and the outer layer pipe for local buckling local can be effectively enhanced, the lamellar tearing problem caused when thick steel plates are adopted is avoided, the problems in the process of processing or making the reinforcing frame and the outer layer pipe are smoothly solved, the production technology is simple, and the production cost is low.

Description

technical field [0001] The invention relates to a power transmission tower and a supporting structure of the power transmission tower, in particular to a power transmission tower and a supporting column of the power transmission tower. Background technique [0002] In the large-span iron tower, the load borne by the iron tower is relatively large. The main material of the steel pipe concrete is used at the bottom of the whole tower. Due to the force requirements, the diameter of the steel pipe is getting larger and larger. However, due to the limitation of the process and equipment, the thickness of the steel pipe can be rolled. Certain limitations may cause the problem that the diameter-thickness ratio of large-diameter steel pipes exceeds the limit. [0003] As a thin-walled steel pipe member sensitive to defects, when its diameter-thickness ratio is large, its ultimate bearing capacity is often greatly reduced due to the existence of initial defects, and local buckling oc...
