Perpendicularity self-correcting device for reinforcement cage

Abstract

The invention discloses a perpendicularity self-correcting device for a reinforcement cage. Main components of the device comprise an outer steel casing and an inner steel casing, the inner steel casing is fixed to the outer steel casing through a first connecting rod, a second connecting rod, a pressure-bearing steel plate, a tension-bearing screw rod and a pressure-bearing screw rod, a jack is fixed through a screw rod and a nut, a third connecting piece and a fourth connecting piece are arranged at the top end of the jack, transmission force acts on the inner steel casing through the connecting pieces, so that the perpendicularity of lowering of the reinforcement cage is corrected, and meanwhile a circuit is controlled to be disconnected or connected through a first rod piece, a secondrod piece, a second steel base plate and a third spring. The device has the beneficial effects that the lowering perpendicularity of the reinforcement cage can be automatically corrected, the size ofthe inner steel casing in the device can be adjusted according to the size of the reinforcement cage, the device is suitable for pile bodies with different pile diameters, the reinforcement cage is located in the center of a pile all the time during lowering, and therefore the thickness of a reinforcement cage protection layer is guaranteed, the pouring quality of a cast-in-place pile is improved,and the hole collapse event caused by hole wall collision in the construction process is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a self-correcting device for the verticality of a reinforcement cage. Background technique [0002] With the development of modern industry, cast-in-situ piles are widely used in various buildings in the field of civil engineering, but it is difficult to ensure the verticality when lowering the steel cage in the project, and it is impossible to accurately ensure the verticality to meet the use requirements through manual adjustment, and In the process of lowering the reinforcement cage, it is easy to collide with the hole wall, resulting in hole collapse and other events, and in the project, due to the verticality of the reinforcement cage, it is easy to have the problem that one side of the protective layer is too large and the other is smaller, which affects the pouring quality of the cast-in-situ pile.
