Different-grades-of-concrete combined isolation device

Abstract

The invention provides a different-grades-of-concrete combined isolation device. The different-grades-of-concrete combined isolation device comprises a base. The base comprises a supporting frame, a whole-thread rotating shaft and a drawing groove frame, the supporting frame is shaped like the Chinese character "ji", the whole-thread rotating shaft is arranged in the middle position of the supporting frame in a penetrating mode, the drawing groove frame is welded to the middle position of the whole-thread rotating shaft, and the drawing groove frame is a rectangular frame. Fixing nuts are arranged on the two ends, located at the outer side of the supporting frame, of the whole-thread rotating shaft, drawing strips are arranged in the drawing groove frame, and the upper portion of gaps of the drawing strips are filled with wedge-shaped plugs. According to the different-grades-of-concrete combined isolation device, the problem of high and low grade concrete confusion is solved, and the requirement of strong columns and weak beams is met.

Description

Technical field [0001] The invention relates to the field of construction technology, in particular to a concrete combined isolation device of different grades. Background technique [0002] As land resources become more and more scarce and high-rise buildings continue to increase, in order to reduce engineering costs and to meet the design concept of strong columns and weak beams, the designation of beams and columns of structurally strengthened floors often differs greatly. The conventional method is: the beams and slabs are manually set with steel mesh For lashing, the beam reinforcement mesh is installed before the beam is laid. After the slab surface reinforcement is tied, the steel mesh is cut into strips and then manually tied from the inside. This method mainly has the following shortcomings: The constructors use hands during the construction process The steel mesh is interspersed and fixed in the middle of the steel mesh. Because of the frequent contact with the wire, th...

Problems solved by technology

[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 labels of beams and columns in the structural reinforcement layer are often different. For binding, the beam reinforcement mesh is installed before the beam is placed. After the steel reinforcement binding on the slab surface is completed, the steel wire mesh is cut into strips and then manually tied from the inside. This method mainly has the following disadvantages: the construction workers use their hands Interspersed and fixed steel mesh in the middle of the steel mesh, because it often encounters wires, its hands are easily injured; the size of the steel mesh is larger than the thickness of the plate, which wastes materials, and can only be installed between the upper and lower steel bars, and the concrete will flow during pouring , leading to confusion in the concrete labels of the beam-column joints; the construction speed is too slow, the operation is inconvenient, and the work efficiency is low
