Combined high and low grade concrete separation device

Abstract

The invention discloses a combined type separation device for high-grade concrete and low-grade concrete. The separation device comprises a base, a drawing strip and a corner drawing piece which are mutually independent and can be combined for use; when in use, the base is placed on board steel bars to be bound by banding wires; drawing strips with different specifications are selected to be inserted in the base according to intervals between the steel bars and spliced tightly to prevent the concrete from flowing; other bases are sequentially mounted in place, and are connected and fixed through the corner drawing piece, and then concreted is poured; According to the combined type separation device for high-grade concrete and low-grade concrete, concrete is limited in a specific area due to interception of the device and is prevented from flowing here and there, so that the situation that high-grade concrete and low-grade concrete are disordered is effectively solved, the requirement of strong column and weak beam is met.

Description

technical field [0001] The invention relates to the construction field, in particular to a combined high and low grade concrete separation device. Background technique [0002] As land resources become more and more scarce, high-rise buildings continue to increase. In order to reduce engineering costs and meet the design concept of strong columns and weak beams, the concrete marks of beams and columns in the structural reinforcement layer are often quite different. Net binding, the beam reinforcement net is installed before the beam is placed, but the board is cut into strips and then manually tied from the inside after the board surface reinforcement binding is completed. This method has the following main disadvantages: The fixed steel wire mesh is interspersed in the middle of the mesh, which is often touched by the wire, and the hand is easily injured; the size of the steel mesh is much larger than the thickness of the plate, which wastes materials, and can only be insta...

[0002] As land resources become more and more scarce, high-rise buildings continue to increase. In order to reduce engineering costs and meet the design concept of strong columns and weak beams, the concrete marks of beams and columns in the structural reinforcement layer are often quite different. Net binding, the beam reinforcement net is installed before the beam is placed, but the board is cut into strips and then manually tied from the inside after the board surface reinforcement binding is completed. This method has the following main disadvantages: The fixed steel wire mesh is interspersed in the middle of the mesh, which is often touched by the wire, and the hand is easily injured; the size of the steel mesh is much larger than the thickness of the plate, which wastes materials, and can only be installed between the upper and lower steel bars. The flow of concrete during pouring will cause beams and columns Confusion of joint concrete labels; construction speed is too slow, operation is inconvenient, and work efficiency is low
