Abstract
Description
Technical Field
[0001] The utility model relates to the field of reinforced concrete construction accessories, in particular to a cushion block structure used for steel mesh concrete pouring construction. Background Art
[0002] Concrete pads are also called steel bar protective layer pads. In the construction of reinforced concrete and frame structures, they are placed between the steel bars and the formwork to fix the position of the steel bars, ensure the thickness of the steel bar protective layer, prevent the steel bars from shifting and being exposed and corroded. They are a common way to fix the steel bars. At present, in the field of highway bridges, the bridge leveling layer refers to the leveling layer set on the bridge. Its purpose is to provide a slope for bridge deck drainage and a flat surface for bridge deck asphalt paving, prevent the steel bars from being exposed, thereby ensuring the quality of bridge deck paving and achieving the drainage effect required by the design. In the construction of the leveling layer of highway bridges, the protective layer between the box girder and the leveling layer steel bars generally uses rectangular concrete pads or directly uses the steel bar head to be placed between the steel bars and the formwork to fix the position of the steel bars. This method is relatively primitive, cannot ensure the thickness of the concrete protective layer, and the steel bars of the non-slotted structure are easily displaced after being subjected to external forces and loads. Manual correction is required in the later stage, which requires high labor costs, high labor intensity, and is not economical. Therefore, it causes the shortcomings of insufficient thickness of the leveling layer concrete steel bar protective layer, exposed or corroded steel bars.
[0003] The patent document with announcement number CN217871416U discloses a concrete steel bar protective layer pad, which has a complex appearance, is difficult to operate and prefabricate, has a high production cost, has a complex process, is difficult to promote on a large scale, and is not economical for sporadic and small-scale construction. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a pad block structure for steel mesh concrete pouring construction, which can simply and reliably realize the position fixation of the steel mesh during the concrete pouring process.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a pad structure used for steel mesh concrete pouring construction, including a steel mesh and a pad, the steel mesh is arranged on the pad top surface of the pad, the pad top surface includes at least one transverse groove and at least one longitudinal groove, the transverse groove and the longitudinal groove both extend in the horizontal direction, the transverse groove and the longitudinal groove intersect vertically to form a groove structure, and the steel mesh is arranged in the groove structure.
[0006] Furthermore, the area of the top surface of the pad is smaller than the area of the bottom surface of the pad.
[0007] Furthermore, the top surface of the pad is a rectangle, the bottom surface of the pad is a rectangle, and the line between the geometric center of the top surface of the pad and the geometric center of the bottom surface of the pad is perpendicular to the horizontal plane.
[0008] Furthermore, the top surface of the pad block and the bottom surface of the pad block are transitionally connected via a pad block slope.

It can be promoted on a large scale; 4. It is highly applicable and economical for sporadic and small-scale construction; 5. The device is highly versatile and can be adjusted according to construction requirements. 6. The wedge-shaped slot concrete pad can prevent the displacement of steel bars and the pad from falling off, which is safe and reliable, and reduces labor intensity and labor costs. The utility model is particularly suitable for the concrete pouring of steel mesh. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the utility model.
[0011] Marked in the figure are: transverse groove 1, longitudinal groove 2, pad top surface 3, pad bottom surface 4, pad inclined surface 5. DETAILED DESCRIPTION
[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0013] like Figure 1 The illustrated embodiment is a pad block. The pad block top surface 3 is rectangular, the pad block bottom surface 4 is rectangular, the area of the pad block top surface 3 is smaller than the area of the pad block bottom surface 4, the pad block top surface 3 and the pad block bottom surface 4 are transitionally connected via the pad block inclined surface 5, forming a basic structure in the shape of a cone. The pad block material can be cast from concrete. Such a structure has good stability, ensuring that the steel mesh arranged on the pad block top surface 3 has stable support during the casting process without shaking or position shifting. The steel mesh is an existing structure, also in a grid shape.
[0014] A transverse groove 1 and a longitudinal groove 2 are provided on the top surface 3 of the pad. The transverse groove 1 and the longitudinal groove 2 intersect to form a cross groove structure. In actual use, a plurality of pads are arranged adjacent to each other, and the groove structure formed by the transverse groove 1 and the longitudinal groove 2 of each pad together constitutes a groove grid, and the groove grid is adapted to the bottom grid of the steel mesh, so that the bottom of the steel mesh is stably set in the groove grid to prevent the steel mesh from shaking during the pouring process. This pad structure improves the speed of installing the pad, saves labor, and solves the problem of difficulty in fixing and binding the pad in the bridge leveling layer and high-density steel bar environment. The pad can be made of an on-site wooden formwork or aluminum formwork to make an outer mold of the pad, and then cast in concrete on site, so the production and processing are simple and the cost is low.
[0015] During the actual construction of the bridge deck leveling layer, the pad can be placed under the steel mesh, so that the groove structure of the pad together forms a groove grid that firmly clamps the steel mesh before pouring concrete. The device is simple to construct and easy to operate, and can effectively prevent the displacement of steel bars after being subjected to external forces and loads. It is suitable for large-scale promotion and can be prefabricated in batches. It has strong adaptability to sporadic and small-scale construction and good steel protection effect. Therefore, this pad is highly versatile and the outer mold or concrete pouring height can be adjusted according to construction needs.
[0016] The actual construction method of the pad can refer to the following steps: 1. Level the site and build a 5*5m concrete storage and maintenance area. 2. Make the pad formwork: Use on-site wooden formwork or aluminum formwork to make the pad outer formwork. 3. Cut 20cm steel bars on site. After the concrete of the pad is poured, use the steel bars to groove the top surface 3 of the pad, and then make a horizontal groove 1 and a longitudinal groove 2 on the top surface 3 of the pad. 4. Complete the pouring and moisturizing maintenance of the pad concrete.
