AI Technical Summary

Technical Problem

The existing column base support device cannot effectively prevent the bending problem caused by the contact between the reinforcing bars and the ground when the column with exposed reinforcing bars is turned from horizontal to vertical during the hoisting process.

Method used

A column base support device with protection for hoisting hollow columns with exposed rebar is designed. By rotating the column and using a sleeve frame structure, the rebar is prevented from directly contacting the ground. The rebar is wrapped with slots and sleeve frames, and the rebar is protected in conjunction with hoisting equipment. The rebar is automatically separated in a vertical state.

Benefits of technology

It achieves all-round protection of the reinforcing bars during the hoisting of the hollow column with exposed reinforcement, avoids bending, simplifies the operation process, and improves the quality of mechanical connection.

Abstract

The utility model discloses a column bottom supporting device for hoisting out -of -core cavity column with protection, including outer frame, and rotating column, the rotating column rotates and is arranged in the inside of outer frame, the top of this rotating column is plane and forms and has the placement plane department, the surface of placement plane department is provided with the slot of mouth character type, can accommodate the reinforcing steel bar through the slot in the installation of out -of -core cavity column, still is firmly equipped with the sleeve setting frame on the placement plane department, and the sleeve setting frame is at the outside of slot, through the design of the utility model, can carry out the comprehensive protection to the reinforcing steel bar of out -of -core cavity column bottom protruding, and follow out -of -core cavity column by horizontal and turn to vertical state, when this is replaced by the device originally reinforcing steel bar and ground contact, realizes the protection to reinforcing steel bar, and after hoisting after out -of -core cavity column turns to vertical state, realizes the separation with the device through the promotion of out -of -core cavity column, does not need manual operation, and the deficiency existing in the prior art structure is improved.
