Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a combined anisotropic steel mesh for building construction. Background Art

[0002] Steel mesh, also known as welded steel mesh, is made from rebar or low-carbon steel wire, cold-drawn into a crescent-shaped ribbed steel. Welding is performed using a dedicated GWC mesh welding machine, with computer-controlled welding procedures. The welded mesh is uniform and high-quality, with virtually no change in the mechanical properties of the steel before and after welding. The use of steel mesh can minimize cracks in factory structures, enhance structural stability, reduce vibration, and further improve the integrity of the structure.

[0003] The traditional steel bar welded mesh is a "double-layer one-way welded mesh", that is, the longitudinal and transverse stress-bearing steel bars are welded together. When processing the mesh, one main bar is welded on one side along the long side, leaving the long end, and the other three directions are short ends, as shown below Figure 1 As shown. During the construction of the slab reinforcement base mesh, the long end is first inserted into the beam, then moved in the opposite direction to ensure that both sides meet the anchorage length within the beam. The long end is supplemented by loosely tying single bars. The short side of the steel mesh does not meet the anchorage length required to extend into the beam (due to the presence of beam stirrups, after the steel mesh is extended into the beam in one direction, the anchorage length in the other two directions perpendicular to that direction cannot be met by parallel movement of the mesh and supplementing single bars). Additional steel bars must be loosely tied through the beam to ensure the mesh meets the anchorage length within the beam. This significantly slows the construction period and reduces construction efficiency. Utility Model Content

[0021] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0023] The embodiment of this specification provides a combined anisotropic steel mesh for construction. Figure 2 As shown, it includes a transverse mesh 1 and a longitudinal mesh 2.

[0024] Wherein, a first long end 11 is provided at each end of the transverse mesh 1, and the long end is used to connect with the beam, including a plurality of first stress-bearing bars 12 arranged in parallel and a first vertical rib 13 fixing the plurality of first stress-bearing bars 12; in a possible implementation, the plurality of first stress-bearing bars are arranged on the same plane, and the plurality of first stress-bearing bars are arranged at equal intervals. A second long end 21 is provided at each end of the longitudinal mesh 2, including a plurality of second stress-bearing bars 22 arranged in parallel and a second vertical rib 23 fixing the plurality of second stress-bearing bars 22; in a possible implementation, the plurality of second stress-bearing bars are arranged on the same plane. The plurality of second stress-bearing bars are arranged at equal intervals. As Figure 3 As shown, the transverse mesh is arranged crosswise with the longitudinal mesh. The transverse mesh can be anchored in the beam via the first long end, while the longitudinal mesh is anchored in the beam via the second long end. It should be noted that during construction, the longitudinal and transverse reinforcement bars are respectively extended into the beam to ensure that both sides meet the anchorage length in the beam (avoiding overlap of the anchorage extending into the beam).

[0025] It is further explained that compared with traditional manual binding of steel bars, this embodiment can significantly improve the quality of steel bar engineering. The welded mesh has high mesh stiffness, good elasticity, and uniform spacing. When pouring concrete, the steel bars are not easily locally bent, and the thickness of the concrete protective layer is easy to control and uniform. In bridge deck paving, the measured qualified rate of the welded mesh protective layer is above 95%.

[0026] Improved construction speed: The use of welded mesh significantly reduces on-site installation hours and saves space for rebar processing. Given the same amount of rebar, laying a single layer of 1,000 kg of welded mesh requires approximately four working hours, a double layer requires over six working hours, and manual tying requires 22 working hours. This saves approximately 50% to 70% of the labor required for manual tying.

[0027] Improve construction convenience: Taking the standard span of (4.8*4.8m) as an example, the double-layer unidirectional steel mesh further refines and decomposes the steel mesh in a unit, so that the mass of the single mesh is further reduced. The reduced mesh mass makes it more convenient for workers to carry it during the construction process. The stiffness of the single-layer unidirectional mesh is reduced compared to the steel mesh, which is more conducive to the installation of the mesh at the beam-column node position.

[0028] Enhances concrete crack resistance: The intersections of artificial steel wire ties are prone to slippage, weakening the bond between the steel and concrete and causing cracks. Welded mesh welds can withstand both compressive and shear forces. The longitudinal and transverse reinforcements form a mesh structure, providing both bonding and anchoring. When welded mesh rebar is constructed with a smaller diameter and denser spacing, the increased number of welds per unit area further enhances concrete crack resistance, reducing the incidence of cracks by over 75%.

[0029] Comparison of materials used in double-layer unidirectional steel mesh and single-layer bidirectional steel mesh (longitudinal meshes BO1, BO2, transverse mesh B03):

[0031]

[0032] 4.8m*4.8m overlap method net plan material table 2

[0033]

[0034]

[0035] The difference in dosage between the two solutions: 10.55kg

[0036] The standard span area is 23.04㎡, which uses an extra 10.55kg, which is only 0.457kg per 1㎡.

[0037] Summary: When the overlap method is used for mesh construction, the overlapped parts are weak points and cracks are likely to occur in the later stage. However, when the distributed reinforcement method is used for mesh construction, the main load-bearing steel bars in both directions are not disconnected, so there will be no cracks in the floor slab in the later stage.

[0038] When using the distribution reinforcement method to lay out a 4.8m*4.8m span, only 20 tying points are needed for positioning. The overlap method requires a total of 212 tying points in the overlap area, which is nearly 10 times the difference. In addition, the overlap method increases the on-site tying workload and labor intensity of the workers.

[0039] For further optimization, please refer to Figure 4 As shown, the first long end is provided with an anti-slip protrusion 3 to increase the contact area with the poured concrete and improve the stability of the connection.

[0040] It should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, commodity, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, commodity, or apparatus that includes the element.

[0041] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
