AI Technical Summary

Technical Problem

The existing spliced ​​concrete poles rely on bolt connections, which are susceptible to oxidation and corrosion from the outdoor environment, leading to a decrease in preload and structural failure. This makes it impossible to guarantee the stability and durability of the poles throughout their entire life cycle.

Method used

It adopts a connection method of socket, plug and stop block, and forms a pre-tight fit between plug and slot through plug-in and slot. It abandons the bolt force form and combines the load-bearing design of differentiated plug part to realize the surface contact load transfer.

Benefits of technology

The assembly process has been simplified, assembly efficiency has been improved, and bolt oxidation and corrosion problems have been avoided, significantly improving the stability and durability of the poles and meeting the needs of engineering applications.

Abstract

The present application relates to the technical field of fabricated concrete electric pole, and particularly discloses a modular fabricated concrete electric pole, which comprises connecting components and at least two pole bodies, the pole body is integrally poured and formed by wrapping a steel reinforcement cage with UHPC material, and the connecting components are used for coaxial butt joint and fixation of the two adjacent pole bodies; the connecting component comprises a socket, a plug and a stop block, the socket and the plug are respectively fixed at the two end portions of the pole body; a plurality of insertion grooves are equidistantly formed on the outer circumferential surface of the socket, the insertion grooves comprise an insertion groove and a clamping groove arranged in an L shape, and one end of the insertion groove extends to the end surface of the socket. The present application effectively optimizes the structural layout of the connecting part, cooperates with the socket of the hollow structure, realizes the lightweight design of the electric pole, reduces the self-weight of the pole end and the wind vibration force response, and further improves the economy and the whole life cycle use durability of the overall structure of the electric pole under the premise of ensuring the connection safety.
