Recycled conical wall drilling device

Abstract

The invention discloses a recycled conical wall drilling device, and aims at solving the problems that when an existing conical sleeve tube is dismantled, the force borne by the sleeve tube is nonuniform when knocking is conducted by adopting a dismantling tool, a small head of the sleeve tube is easily damaged, the using time of the sleeve tube cannot be ensured, the recycling time of a wall drilling sleeve tube is reduced, and therefore the service life of the wall drilling sleeve tube is reduced. The device comprises a conical wall drilling sleeve tube body and a dismantling handle, a microthreaded groove is formed in the outer surface of the conical wall drilling sleeve tube body, the outer surface of the conical wall drilling sleeve tube body is coated with a wear resisting layer, and foot cups are in threaded connection with the bottom end of the conical wall drilling sleeve tube body. The recycled conical wall drilling device has the advantages that the conical wall drilling sleeve body is driven to rotate by a rotary handle by rotating the dismantling handle, so that the conical wall drilling sleeve tube body is dismantled through rotation, a knocking manner is replaced with a rotation manner, and therefore the reduction of the service life caused by nonuniform force bearing by adopting knocking is avoided.

Description

Technical field: [0001] The invention relates to the field of a tapered wall-piercing sleeve, in particular to a tapered revolvable wall-piercing device. Background technique: [0002] The tapered sleeve is mainly used together with the wall-penetrating screw (tie bolt) to tie the inner and outer formwork of the wall, bear the lateral pressure of the concrete and other loads, and ensure that the distance between the inner and outer formwork can meet the design requirements. requirements, but also the fulcrum of the formwork and its supporting structure. It can be called an upgraded version of the disposable sleeve, which can be taken out of the wall and reused. [0003] The current new tapered casing is generally produced with ABS raw materials, with high strength and good toughness, which can avoid grout leakage. After the concrete wall is poured, the wall-penetrating screw can be taken out directly, and the tapered casing can be removed through the removal tool. take out...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a tapered wall-penetrating device that can be used in a turnaround, so as to solve the problem that when disassembling the tapered sleeve proposed above, it needs to be knocked with a disassembly tool, which will cause the sleeve to be stressed unevenly and easily The small head of the bushing is damaged, and the number of times the bushing can be used cannot be guaranteed, resulting in a reduction in the number of turnovers of the wall bushing, thereby reducing the service life of the wall bushing
