Reinforced steel pipe foam concrete electric power tower

Abstract

The invention discloses a reinforced steel pipe foam concrete electric power tower which comprises four main pillars and supporting rods among the main pillars. The main pillars are conical reinforced steel pipe foam concrete pillars, and the supporting rods are connected with conical metal hoops of the outer surfaces of the conical steel pipe foam concrete pillars. The conical steel pipe foam concrete pillars are the reinforced steel pipe foam concrete pillars, and the raw material of the reinforced steel pipe foam concrete pillars is reinforced foam concrete. The reinforced foam concrete comprises waste brick dregs, coal ash, limestone powder, sand, gypsum, composite additives, liquid foaming agents and steel fibers. The tower is filled with the cast reinforced foam concrete, and therefore the bearing force of a steel pipe is increased, the weight of the tower is reduced, and the cost of the tower is reduced.

Description

technical field [0001] The invention relates to a reinforced steel pipe foam concrete power tower, which belongs to the field of construction engineering. Background technique [0002] The steel pipe foam concrete composite column refers to a composite column in which the steel pipe is filled with foam concrete and the outer wall of the steel pipe is provided with a concrete protective layer. [0003] CFST columns were introduced into China in the mid-1960s. In less than 50 years, CFST technology has developed rapidly both in theory and technology. Most of the CFST columns used in existing industrial and civil buildings are It is simply made by pouring ordinary cement concrete in the steel pipe. Early concrete-filled steel tube columns greatly compensated for the high brittleness of concrete through the lateral restraint of the steel tubes on the concrete; at the same time, the concrete filled in the steel tubes limited the deformation of the steel tubes. Because its compr...

AI Technical Summary

Problems solved by technology

First of all, the strength and stiffness of CFST columns have been greatly increased, but their seismic capacity has not been improved very well. Under the repeated action of earthquake force, the concrete inside the steel pipes is prone to brittle failure, resulting in a decrease in the bearing capacity of the columns.

Secondly, steel pipes will deform under high temperature conditions, and these hazards will affect the stress of concrete columns

[0004] Chinese patent application 201310047960.9 proposes a steel pipe foam concrete composite column and its construction method, but its structure is complex, its quality is too large, and its cost is relatively high
