Description

Technical Field

[0001] The present application relates to the technical field of steel bar support, and in particular to a double-layer bidirectional steel bar support frame for cast-in-place concrete. Background Art

[0002] In the construction process of building projects in the new era, cast-in-place reinforced concrete floor slabs are usually used; cast-in-place floor slabs have good integrity, can ensure the safety and stability of the building, and have good earthquake resistance and anti-seepage performance, so they are widely used.

[0003] In cast-in-place slabs, double-layer bidirectional steel bars are generally installed. Double-layer bidirectional steel bars mean that during the steel bar binding stage of the slab, a lower steel mesh and an upper steel mesh are installed. The lower steel mesh includes multiple lower transverse bars arranged along the X direction and multiple lower longitudinal bars arranged along the Y direction. The lower transverse bars and the lower longitudinal bars are bound and fixed. The upper steel mesh includes multiple upper transverse bars arranged along the X direction and multiple upper longitudinal bars arranged along the Y direction. The upper transverse bars and the upper longitudinal bars are bound and fixed.

[0004] However, the above-mentioned related technologies have the following problems: during the pouring of the floor slab, workers need to step on the double-layer bidirectional steel bars, which are not only compressed by the weight of the concrete, but also by external forces such as workers stepping on them and vibrating rods, which can cause the steel mesh to sink and shift, resulting in problems such as too small a distance between the upper and lower layers of the steel mesh and insufficient steel protection layer. Further improvements are needed. Utility Model Content

Thus, the upper transverse reinforcement 12 is supported by the first support part, and the lower longitudinal reinforcement 11 is supported by the second support part, so that the upper and lower steel meshes can be supported to ensure that the upper and lower steel meshes are fixed without sinking or shifting, so that the protection of the steel mesh can meet the standards and the construction quality of the floor slab can meet the design requirements.

[0035] The support member includes two symmetrically arranged lower support ribs 21 and an upper support rib 22 arranged between the two lower support ribs 21; the cross section of the upper support rib 22 is U-shaped and its opening is arranged downward, and the opening of the upper support rib 22 and the two sides of the upper support rib 22 are integrally formed with bending ribs 2, and one end of the bending rib 2 away from the upper support rib 22 is integrally formed with the end of the lower support rib 21; thus, the bending rib 2 plays the role of connecting the upper support rib 22 and the lower support rib 21.
