Technical Field

[0001] The utility model belongs to the technical field of steel mesh processing, and in particular relates to a spacer-free three-dimensional steel mesh. Background Art

[0002] The application of steel mesh in concrete structures can effectively improve the mechanical properties, durability and construction efficiency of the structure, making the building safer, more stable and durable.

[0003] During the construction process, since the steel mesh needs to be manually tied with pads or the pads are placed in advance, the pads are often placed in an offset position or insufficiently during construction, causing the steel mesh pads to become unstable or misplaced. For example, the pads do not fit the concrete surface, the pads are not firmly installed, and the pads are deformed or damaged, which may affect the position of the steel mesh in the concrete structure and further affect the mechanical properties of the structure. Therefore, a pad-free steel mesh that avoids the use of a large number of concrete pads is needed to enhance the integrity of the concrete. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a three-dimensional steel mesh without pads in view of the deficiencies in the above-mentioned prior art. The utility model has a simple structure and a reasonable design. By arranging the transverse steel bars as three-dimensional steel bars, it is convenient to form a three-dimensional steel mesh, thereby forming a support in the formwork, so that there is a natural gap between most of the steel bars and the formwork. There is no need to use concrete pads in the formwork to raise the three-dimensional steel mesh, which enhances the integrity after concrete pouring and has strong practicality.

[0026] Example 1

[0027] like Figure 1 As shown, the utility model comprises a three-dimensional steel mesh, first lap ribs are arranged on both the left and right sides of the three-dimensional steel mesh, and second lap ribs are arranged on both the upper and lower sides of the three-dimensional steel mesh.

[0028] The three-dimensional steel mesh includes transverse steel bars 7 and longitudinal steel bars 8 arranged in a grid shape, and the transverse steel bars 7 are three-dimensional steel bars.

[0029] The first lap reinforcement includes a first transverse side reinforcement 1 and a first longitudinal side reinforcement 2, one end of the first transverse side reinforcement 1 is connected to the end of the transverse reinforcement 7, and the other end of the first transverse side reinforcement 1 is provided with a first bent portion 3 bent downward, and the ends of the first bent portions 3 of multiple first transverse side reinforcements 1 are all connected to one first longitudinal side reinforcement 2.

[0030] The second lap reinforcement includes a second transverse side reinforcement 4 and a second longitudinal side reinforcement 5, one end of the second longitudinal side reinforcement 5 is connected to the end of the longitudinal steel bar 8, the other end of the second longitudinal side reinforcement 5 is connected to the second transverse side reinforcement 4, and a second bent portion 6 bent downward is provided in the middle of the second transverse side reinforcement 4 between two adjacent second longitudinal side reinforcements 5.

[0031] In actual use, by setting the transverse steel bars 7 as three-dimensional steel bars, it is convenient to form a three-dimensional steel mesh, thereby forming a support in the formwork, so that there is a natural gap between most of the steel bars and the formwork, and there is no need to use concrete pads in the formwork to raise the three-dimensional steel mesh, which facilitates the accurate positioning of the three-dimensional steel mesh during placement and also enhances the integrity of the concrete after pouring.

[0032] It should be noted that by providing the first lap rib and the second lap rib, it is convenient for two adjacent three-dimensional steel meshes to overlap each other. By providing the first bent portion 3 and the second bent portion 6, not only the overlapping parts of the two adjacent three-dimensional steel meshes are supported, but also the technicians can determine the overlapping length with reference to the bent part, which facilitates the uniformity of the overlapping length and improves the overlapping quality of the three-dimensional steel mesh.

[0033] In this embodiment, a third bent portion 9 bent downward is provided in the middle of the transverse reinforcement 7 between two adjacent longitudinal reinforcements 8 .

[0034] In actual use, by providing the third bent portion 9 that bends downward, the transverse reinforcement 7 can be raised and most of the transverse reinforcement 7 can be horizontal straight reinforcements, thereby ensuring the continuity of the transverse reinforcement 7 and having a smaller deadweight.

[0035] It should be noted that the first curved portion 3, the second curved portion 6 and the third curved portion 9 have the same degree of curvature, so that the first transverse side reinforcement 1, the second transverse side reinforcement 4 and the transverse reinforcement 7 are all lifted to the same height, ensuring the overall horizontality of the three-dimensional steel mesh.

[0036] Example 2

[0037] like Figure 2 As shown, the present embodiment is different from the embodiment 1 in that a U-shaped rib 10 for raising the transverse reinforcement 7 is additionally connected to the transverse reinforcement 7 .

[0038] In this embodiment, a U-shaped rib 10 is connected to the middle of the transverse reinforcement 7 between two adjacent longitudinal reinforcements 8 .

[0039] In actual use, by setting the U-shaped ribs 10, it is convenient to adjust the height of the U-shaped ribs 10 individually according to the required height of the three-dimensional steel mesh, and then fix the adjusted U-shaped ribs 10 in sequence to the middle part of the transverse steel bars 7 between two adjacent longitudinal steel bars 8, which not only achieves the raising of the transverse steel bars 7 and ensures the continuity of the transverse steel bars 7 themselves, but also improves the structural stiffness of the middle part of the transverse steel bars 7. At the same time, the U-shaped ribs 10 can be processed individually in large quantities, and then directly connected to ordinary straight steel meshes of various sizes to form a three-dimensional steel mesh, which is simple and convenient to operate.

[0040] Example 3

[0041] like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that in this embodiment, the transverse steel bars 7 are corrugated steel bars.

[0042] In actual use, by setting the transverse reinforcement 7 as a corrugated reinforcement, it is convenient to increase the support points of the transverse reinforcement 7, which not only makes the placement of the three-dimensional reinforcement mesh more stable, but also enhances the overall support force of the transverse reinforcement 7 and has strong flexibility.

[0043] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
