Description

Detachable supporting tripod for reinforcement cage of large pile foundation

Technical Field

The utility model relates to a large-scale pile foundation steel reinforcement cage can dismantle support tripod belongs to the on-the-spot loading and unloading of steel reinforcement cage and transportation field.

Background

The reinforcement cage is a member made by welding or binding and assembling main reinforcement, a stiff skeleton, a stirrup and the like, and is widely applied to pile foundation reinforced concrete structures such as cast-in-situ bored piles, stand columns and the like of bridges and culverts or high-rise buildings.

The large-scale reinforcement cage has the structural characteristics of multiple sections, large self weight, multiple joints, easy deformation and the like.

In order to prevent the framework from deforming in the loading, unloading and transporting processes of the framework reinforcement cage, strip-shaped reinforcements are welded among the upper reinforcement main reinforcements, the lower reinforcement main reinforcements and the reinforcement main reinforcements on two sides of the reinforcement cage to form a fixed supporting tripod in the conventional method, and the deformation of the reinforcement cage in the loading, unloading and transporting processes is avoided through a large number of fixed supporting tripods. Because a large number of fixed supporting tripods are formed by welding reinforcing steel bars, the supporting tripods which are welded and fixed are difficult to remove before the steel reinforcement cage is poured, and finally, the supporting tripods are directly poured into the concrete pile. However, when the concrete structure is an independent columnar member, the reinforcing bars are not needed at the central part inside, and only the reinforcing bars are needed to be arranged under the surface of the concrete member contacting with air, so that a large amount of steel is wasted, and the mechanical property of the pile is influenced to a certain extent.
