Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a device for fixing the vertical reinforcement spacing of a concrete column. Background Art

[0002] During the installation of steel bars and the pouring of concrete in the concrete columns of construction projects, it is easy for the steel bars of vertical columns, especially those of large-diameter columns, to be displaced, the spacing between steel bars to change, and the steel bars to move outwards. This is a difficult point in the quality control of steel bar installation. If there are serious quality problems such as steel bar displacement and spacing change, it will affect the safety of the concrete structure of the construction project.

[0003] Currently, the spacing and deviation are mainly controlled by wire binding, but the control effect is not good. Although remedial measures can be taken after pouring, it increases the labor cost. Therefore, quality control before pouring is particularly important. During the installation of steel bars, the spacing between steel bars should be fixed to prevent the deviation of steel bars, which can effectively ensure the quality of the project.

[0004] Therefore, it is necessary to provide a device for fixing the spacing of vertical steel bars in a concrete column to solve the above-mentioned technical problems. Utility Model Content

[0005] The utility model aims to provide a device for fixing the spacing of vertical steel bars in a concrete column in view of the deficiencies in the prior art. The device is easy to operate and can keep the steel bars in a fixed position without deviation during the concrete pouring process.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A device for fixing the spacing of vertical steel bars in a concrete column comprises a horizontally arranged screw rod, a plurality of sets of fixing assemblies are sleeved at intervals in the length direction of the screw rod, the plurality of fixing assemblies are arranged in the same direction, the fixing assemblies slide left and right on the screw rod and are detachably connected to the screw rod, the fixing assembly comprises a mountain-shaped clip and a mountain-shaped nut sleeved on the outer periphery of the screw rod, one side of the mountain-shaped clip is provided with an arc-shaped concave surface, and the other side is provided with a plane, the concave surface of the mountain-shaped clip is in contact with the outer periphery of the vertically arranged steel bars, the mountain-shaped nut is located on one side of the plane of the mountain-shaped clip, the mountain-shaped clip is tightened and fixed by the mountain-shaped nut, the concave surface of the mountain-shaped clip is provided with an embedding groove, and a magnet is embedded in the embedding groove.

[0008] Preferably, a gasket is provided between the mountain-shaped nuts.

[0009] Preferably, two concave surfaces are symmetrically provided on one side of the mountain-shaped card, and magnets are embedded in the two concave surfaces.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The utility model forms a fixing device through a screw, a mountain-shaped clamp and a mountain-shaped nut, which plays a role in fixing the steel bars at the construction site. The corresponding number of fixing components can be freely configured according to the number of steel bars and the design drawings. The concave surface of the mountain-shaped clamp is used to limit the displacement of the steel bars. At the same time, the magnet embedded in the concave surface can not only further improve the fixing effect of the steel bars, but also play the role of adsorbing and fixing the entire fixing device on the steel bars. No binding operation is required, which saves a lot of operation time and reduces the difficulty of installation. At the same time, the utility model can prevent the vertical column steel bars from deviating outward, causing the steel bar protective layer of the reinforced concrete column to fail to meet the standards. The utility model also has the advantages of easy disassembly, simple production and repeated use. BRIEF DESCRIPTION OF THE DRAWINGS
