Description

Technical Field

[0001] The utility model belongs to the technical field of cast-in-place concrete slabs, and relates to steel bars of cast-in-place concrete slabs, in particular to a stirrup bracket used for erecting steel bars. Background Art

[0002] In the construction of cast-in-place concrete slabs, rafts, bridge decks and concrete surface layers, single-layer or double-layer steel bars are usually set. The double-layer steel bars are specifically divided into slab bottom steel bars and slab surface steel bars. The slab bottom steel bars are located at the lower part of the concrete beam or slab, have a larger diameter, and are mainly used to withstand bending moments and shear forces; the slab surface steel bars are located at the upper part of the concrete beam or slab, have a smaller diameter, and are mainly used to withstand horizontal loads.

[0003] There is a certain distance between the bottom steel bars and the surface steel bars. The traditional fixing method is to install a number of horse stool bars between the bottom steel bars and the surface steel bars, which has the following problems:

[0004] 1. The horse stool reinforcement is a "J"-shaped, plum-shaped or rectangular structure with a small volume. Therefore, it needs to be arranged in large quantities when used and cannot be recycled, resulting in high construction costs. In addition, the horse stool reinforcement structure is unstable, and it is easy to collapse when construction workers walk on the slab reinforcement, posing a safety hazard;

[0005] 2. The height of the horse stool reinforcement is fixed, and it can only be applied to concrete slabs of a single fixed thickness. It cannot be universal, and the scope of application is narrow. The construction of concrete slabs of different thicknesses requires customized horse stool reinforcement of the corresponding height, and the material cost is high;

[0006] 3. When pouring concrete, the trampling of construction workers and the collision of vibrating machinery can easily cause the horse stool reinforcement to be skewed or bent, resulting in insufficient spacing between the bottom steel bars and the surface steel bars, and insufficient thickness of the protective layer, which cannot meet the design requirements, affect the construction quality, and pose a safety hazard.

[0007] Therefore, we propose a stirrup bracket for erecting steel bars to solve the above problems. Utility Model Content
