Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of guardrails for concrete pouring, in particular to a guardrail device which is convenient for pouring concrete at a beam-column joint. Background Art
[0002] At the construction site, the concrete grade of the columns is inconsistent with the concrete grade of the beams and slabs. The concrete strength of the core parts of the beams and columns is particularly important. The concrete used to separate the different grades of beams and columns is a guardrail device.
[0003] Commonly used guardrail devices in the prior art include inflatable gas rods, quick-close nets, etc. However, they are inconvenient to use and prone to water leakage in construction joints, and cannot effectively meet construction needs. For example, although inflatable gas rods are quick, the beams can only be cast after the concrete on the side of the column has initially set. If the interval is too long, it is easy to leak, which not only affects the time of concrete casting, but also poses a great quality risk of water leakage. Quick-close nets have poor stability and are not easy to fix. They are easily deformed or damaged during the casting process, causing the concrete of the beams and columns to fuse with each other, affecting the quality of the concrete at the core nodes. Utility Model Content
[0004] In view of the problems that the existing guardrail devices have unchanged construction, easy water leakage in construction joints, affecting the quality of concrete, and cannot effectively meet the construction needs, the utility model provides a guardrail device which is convenient for pouring concrete at the junction of beams and columns. The utility model is easy to construct, has strong stability, does not leak, and effectively meets the construction needs.
[0005] The technical solution is as follows: a guardrail device that is convenient for pouring concrete at the junction of beams and columns, comprising main bars evenly arranged at the top and bottom, and characterized in that: a "frame-shaped" first inner hoop, a second inner hoop, and a third inner hoop are sequentially provided between the two rows of the main bars, and an inclined steel wire mesh is also provided between the two rows of the main bars, the upper part of the steel wire mesh is connected by binding with the upper end of the first inner hoop and the main bars in the upper row, the middle part of the steel wire mesh is connected by binding with the second inner hoop through a single-leg hoop, and the lower part of the steel wire mesh is connected by binding with the lower end of the third inner hoop and the main bars in the lower row.
[0006] The further feature is that: the single-leg hoop is a straight steel bar with a diameter of 12 mm, and both ends of the straight steel bar have hooks bent to the same side;
[0007] The first inner stirrup, the second inner stirrup and the third inner stirrup are respectively bent into a frame shape by steel bars with a diameter of 12 mm, and the joints at both ends are at an inner corner of the frame shape.
[0008] After adopting the above structure, the guardrail device of the utility model forms a rigid skeleton by bundling the first to third inner stirrups in a frame shape between the main reinforcements, and then forms a guardrail by bundling and connecting the wire mesh, the inner stirrups and the main reinforcements. The overall structure is simple and easy to construct. At the same time, it has strong stability and does not leak during pouring, effectively meeting construction requirements.

[0013] like Figures 1 to 4 As shown, a guardrail device is convenient for pouring concrete at the junction of beams and columns, including upper and lower rows of evenly arranged horizontal main bars 1, and "frame-shaped" first inner stirrups 2, second inner stirrups 3, and third inner stirrups 4 are arranged in sequence between the two rows of main bars 1. The first inner stirrups 2, the second inner stirrups 3, and the third inner stirrups 4 have the same structure, and are respectively bent into a frame shape by steel bars with a diameter of 12 mm, and the joints at both ends are at an inner corner of the frame shape.
[0014] An inclined steel mesh 5 is also provided between the two rows of main bars 1. The steel mesh 5 is formed by wrapping a fine steel mesh on both sides of a rigid steel bar skeleton formed by binding. The fine steel mesh has at least 12 meshes, and the dense performance of the fine steel mesh is used to form a guardrail. The upper part of the steel mesh 5 is connected by binding with the upper end of the first inner stirrup 2 and the upper row of main bars 1, the middle part of the steel mesh 5 is connected by binding with the second inner stirrup 3 through a single-leg hoop 6, and the lower part of the steel mesh 5 is connected by binding with the lower end of the third inner stirrup 4 and the lower row of main bars 1.
[0015] The single-leg hoop 6 is a straight steel bar with a diameter of 12 mm, and both ends of the straight steel bar are provided with hooks bent to the same side.
[0016] When in use, the guardrail of the utility model is arranged at a 45-degree oblique angle at the junction of the column and beam, and then fixed by binding to form a stable guardrail.
[0017] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by anyone familiar with the technology within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
