Description

Technical Field

[0001] The utility model relates to a construction tool for reinforced floor, in particular to a steel bar reset device for reinforced floor. Background Art

[0002] The stools are mainly used between the upper and lower layers of steel bars of cast-in-place concrete floors, and are used to support and fix the upper steel bars of structural slabs or foundation slabs, so that a predetermined distance is maintained between the upper and lower layers of steel bars, which plays an important role in controlling the effective height of the slab section, the thickness of the steel bar protection layer and ensuring the mechanical properties of the slab structure. In traditional construction, the method of laying a runway above the steel bars is usually adopted to solve the problem of workers stepping on the steel bars, but it is impossible to avoid the rolling of tools such as laser screed machines and handcarts during construction operations on the steel bars, resulting in the deformation of the stools, the displacement and bending of the steel bar positions, reducing the normal function of the stressed steel bars in the concrete to bear and transfer forces, and there are quality problems that the bearing capacity of the concrete floor cannot meet the structural function requirements.

[0003] Publication No. CN220814557U - A stool for cast-in-place concrete floor and Publication No. CN220814557U - A stool for cast-in-place concrete floor both disclose a stool that can fix the upper and lower layers of steel bars, but it is easy to form an obstacle above the upper steel bars, affecting the passage and operation of workers; and the upper steel bars are prone to twist and deform at the stools, affecting the performance of the upper steel bars.

[0006] Further, the connecting part includes two symmetrically arranged arc-shaped plates. The lower ends of the arc-shaped plates are fixedly connected to the bracket, and the upper ends of the two arc-shaped plates are close to each other, so that the two arc-shaped plates and the bracket form a hoop structure.

[0007] Further, the limiting part includes a vertically arranged limiting plate, the lower end of the limiting plate is fixedly connected to the bracket, the two limiting parts are arranged in mirror symmetry with respect to the center point of the bracket, and the two connecting parts are arranged symmetrically with respect to the center point of the bracket.

[0008] Further, the bracket is a cross-shaped structure composed of strip plates, the connecting parts and the limiting parts are respectively located at the free ends of the strip plates, and the bottom surfaces of the free ends of the strip plates are all supported on the compression springs.

[0015] A steel bar reset device for a reinforced floor slab, as Figure 1As shown in the figure, it includes a vertically arranged compression spring 6. At the top of the compression spring 6, there is a flat-shaped bracket 100. The threaded coil at the upper end of the compression spring 6 supports on the bottom edge of the bracket 100 and is fixedly connected thereto, and the bracket 100 is horizontally arranged. The middle part of the bracket 100 is located on the axis of the compression spring 6; the diameter of the compression spring 6 is greater than or equal to one-fourth of the width of the steel bar grid in the reinforced concrete floor and less than or equal to one-third of the width of the steel bar grid in the reinforced concrete floor; to stably set the present utility model at a set position, for example, the middle part of the bracket 100 corresponds to the node of the connected steel bar grid, and the top surface of the bracket 100 is supported at four adjacent steel bar grid nodes and the steel bars connected to the connection nodes. On the top surface of the bracket 100, there are two connecting parts 3 for fixedly connecting to the steel bars and two limiting parts 4 for blocking on the side of the steel bars. The two connecting parts 3 and the two limiting parts 4 are respectively located around the bracket 100; to facilitate the setting of the two connecting parts 3 on the bracket 100, the connecting part 3 includes two symmetrically arranged arc-shaped plates. The lower ends of the arc-shaped plates are fixedly connected to the bracket 100, specifically by welding or integral connection. The upper ends of the two arc-shaped plates are close to each other, so that the two arc-shaped plates and the bracket 100 form a hoop structure. To facilitate the setting of the two limiting parts 4 on the bracket 100, the limiting part 4 includes a vertically arranged limiting plate. The lower end of the limiting plate is fixedly connected to the bracket 100, specifically by welding or integral connection. The two limiting parts 4 are mirror-symmetrically arranged about the center point of the bracket 100, and the two connecting parts 3 are symmetrically arranged about the center point of the bracket 100; thus, the two limiting parts 4 are respectively located on both sides of the steel bar, and the two connecting parts 3 are connected to the same steel bar, thereby improving the connection effect between the bracket 100 and the steel bar grid and preventing it from falling off due to external forces.

[0016] Among them, to facilitate the processing of the bracket 100, the bracket 100 is a cross-shaped structure composed of strip plates 1. The connecting part 3 and the limiting part 4 are respectively located at the free ends of the strip plates 1. The bottom surfaces of the free ends of the strip plates 1 are all supported on the compression spring 6. To make the strip plates 1 in the same plane and facilitate the support cooperation between the bracket 100 and the compression spring 6, the bracket 100 includes a long strip plate 12. On both sides of the middle part of the long strip plate 12, there are fixedly connected short strip plates 11. The long strip plate 12 and the short strip plates 11 are in the same plane; the connecting part 3 is located at the free end of the short strip plate 11, and the limiting part 4 is located at the end of the long strip plate 12. To facilitate the fixed connection between the bracket 100 and the compression spring 6, the two free ends of the long strip plate 12 are bent downward and inward to form hook parts 5. The hook parts 5 are wound around the threaded coil, thereby fixedly connecting the bracket 100 to the compression spring 6.

[0017] During the construction of the floor, such as Figure 2As shown, after the upper-layer steel bars are tied and a steel bar grid is formed, place the present utility model below the steel bar grid and directly below the binding intersection of the longitudinal steel bars and the transverse steel bars. Support it below the steel bars through the strip plate 1, and the connecting part 3 is clamped on the steel bars on both sides of the node. The connecting part 3 is located in the middle of the side of the steel bar grid, so as to realize the fixed connection between the present utility model and the floor steel bars; after installing the present utility model, the two limiting parts 4 are respectively limited on both sides of another steel bar, so as to prevent the bracket 100 from rotating. Under the action of the present utility model, the load is released through the local collapse of the upper-layer steel bars. Under the support of the compression spring 6 and the elastic deformation of the steel bars themselves, it returns to its original position, avoiding the compression and distortion of the upper-layer steel bars and avoiding the quality problem that the bearing capacity of the concrete floor cannot meet the structural function requirements.
