[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0032] like Figure 1 As shown, this embodiment provides a jig for welding shaped steel mesh, including a back plate 1, a side baffle 2, a bottom baffle 3, a slide rail groove 4, a movable insert plate 5, a positioning steel bar 6, and a fixing component 7.

[0033] In this embodiment, the side baffle 2 and the bottom baffle 3 are fixedly connected to the back plate 1. All three components—back plate 1, side baffle 2, and bottom baffle 3—are made of steel. Preferably, the side baffle 2 and the bottom baffle have the same thickness, while the back plate 1 has a greater thickness than both the side baffle 2 and the bottom baffle. Furthermore, anti-slip support feet are provided at the bottom of the side baffle 2 to enhance the stability of the fixture placement.

[0034] Specifically, the back plate 1 is provided with a slide rail groove 4 extending along its length. Preferably, the slide rail groove 4 is a rectangular through groove extending through the length of the back plate 1. The movable insert plate 5 is slidably assembled in the slide rail groove 4, and the fixing member 7 is used to lock and fix the movable insert plate 5 to the target position of the slide rail groove 4. In this embodiment, the fixing member 7 is a bolt. The positioning reinforcing bars 6 include multiple ones, and the multiple positioning reinforcing bars 6 are evenly distributed on the movable insert plate 5 along the length of the movable insert plate 5.

[0035] This jig for welding shaped steel mesh has a slide rail groove 4 extending along its length on the back plate 1, and the movable insert plate 5 can be slidably assembled in the slide rail groove 4. This forms a positioning structure that ensures the dimensional accuracy and mesh uniformity of the steel mesh by precisely positioning it longitudinally through the movable insert plate 5 and adjusting the lateral spacing of the slide rail groove 4. This improves the compatibility of the mesh with other building components. At the same time, by adjusting the lateral spacing of the movable insert plate 5 in the slide rail groove 4, it can accommodate steel mesh of different specifications, making it more versatile. Furthermore, the side baffle 2 and bottom baffle 3 are fixedly connected to the back plate 1 to form a vertical structure, which facilitates operation.

[0036] As an optional implementation, the side baffle 2 is inclined outward relative to the back plate 1 at an angle of 3°-8°. In this embodiment, the side baffle 2 is inclined outward from the center of the back plate 1, with the inclination reference being the vertical plane of the back plate, forming an angle of 3°-8° with the surface of the back plate. This arrangement provides natural guidance for the transverse reinforcing bars, facilitating operators to quickly place the reinforcing bars against the side baffle, reducing the manual adjustment time for rebar alignment, and improving operational efficiency.

[0037] In this embodiment, the inclination angle of the side baffle 2 is 5°. Engineering practice has verified that the inclination angle of 5° is the optimal inclination angle of the side baffle 2, which can ensure the stable guidance and fall prevention of steel bars of different diameters, and will not cause the stress deviation of the steel bars due to the excessively large angle, or will not cause the failure to play a guiding role due to the excessively small angle.

[0038] As an optional embodiment, the bottom baffle 3 is arranged to be inclined upward relative to the horizontal direction, and the inclination angle is 3°-8°. In this embodiment, the inclination direction of the bottom baffle 3 is toward the upper side of the back plate 1, the inclination reference is the horizontal ground, and the inclination angle range is 3°-8°. The inclination angle of 3°-8° makes the longitudinal steel bars closely adhere to the bottom baffle 3 by using the gravity, and the inclination structure not only provides reliable support for the longitudinal steel bars, but also guides the steel bars to quickly align, reduces the adjustment time of the steel bar placement, and improves the processing efficiency; at the same time, the inclination structure avoids the end of the longitudinal steel bar from being raised, and ensures the accuracy of the length size of the mesh.

[0039] In this embodiment, the inclination angle of the bottom baffle 3 is 5°. When in use, the 5° inclination angle of the bottom baffle 3 and the 5° inclination angle of the side baffle 2 form complementation, the positioning reference of the transverse steel bar and the longitudinal steel bar are matched with each other, the mesh uniformity error is smaller, and the mesh deformation problem caused by the uncoordinated longitudinal and transverse positioning of the traditional mold is solved. Moreover, the accurate 5° inclination angle makes the contact area of the longitudinal steel bar and the bottom baffle 3 uniform, avoids the deformation of the steel bar caused by the local stress concentration, and improves the overall structural strength and stability of the mesh after welding.

[0040] As an optional embodiment, the number of the slide rail grooves 4 is three, and the three slide rail grooves 4 are distributed in parallel along the longitudinal direction of the back plate 1.

[0041] The three slide rail grooves 4 form a three-point support structure, compared with a single or two slide rail grooves 4, the movable plug plate 5 does not tilt and does not shake when sliding, the positioning accuracy is effectively improved, and the deviation of the steel bar spacing caused by the inclination of the movable plug plate 5 can be avoided. At the same time, the three slide rail grooves 4 make the steel bar pressure borne by the movable plug plate 5 uniformly dispersed, reduce the risk of deformation of the movable plug plate 5, and prolong the service life of the mold. The vertically parallel distribution of the slide rail grooves makes the adjustment direction of the movable plug plate consistent with the transverse spacing direction of the steel mesh, the adjustment process is intuitive and controllable, and the operator can directly read the spacing value through a steel ruler, thereby reducing the adjustment time.

[0042] In this embodiment, the specific positions of the three slide rail grooves 4 are respectively arranged at the top edge, the bottom edge of the back plate 1, and the longitudinal center of the back plate 1. Through the three-point distribution of the top, bottom and center, the support points of the movable plug plate 5 cover the entire length of the movable plug plate 5, so that the movable plug plate 5 does not bend and deform even when processing a large-width mesh, and the positioning accuracy is stable.

[0043] This embodiment also provides a method for preparing a reinforcing mesh, using the aforementioned jig for welding shaped reinforcing mesh, including the following steps:

[0044] S1: Fabricate and install the fixture: Position, assemble and fix the back plate 1, side baffle 2 and bottom baffle 3, process the slide rail groove 4 extending along its length on the back plate 1, and slidably assemble the movable insert plate 5 into the slide rail groove 4.

[0045] Specifically, during positioning and assembly, the side baffle 2 is tilted outward by 5° relative to the back plate 1, and the bottom baffle 3 is tilted upward by 5° relative to the horizontal direction. The back plate 1 and the bottom baffle 3 are set perpendicularly. After the angle is adjusted to the correct position, the three are welded and fixed. At the same time, three vertically parallel sliding rail grooves 4 are machined on the back plate 1 for the installation of the movable insert plate 5.

[0046] S2: Adjusting the fixture: Select an appropriate number of movable inserts 5 according to the vertical spacing of the target steel mesh, slide and adjust the horizontal spacing of the movable inserts 5 to match the horizontal spacing of the target steel mesh, and lock and fix the movable inserts 5 with the fasteners 7.

[0047] S3: Rebar Placement and Welding: Determine the cutting length of the rebar according to the length of the back plate 1, and place the horizontal and vertical rebars in sequence, aligning the horizontal rebars with the side baffle 2 and the vertical rebars with the bottom baffle 3. Stack multiple layers of rebars in sequence until the ends of the rebars abut against the bottom positioning rebar 6. Weld all rebar intersections in sequence.

[0048] Specifically, the transverse and longitudinal reinforcing bars are placed sequentially in layers, aligning the transverse reinforcing bars with the side baffle 2 and the longitudinal reinforcing bars with the bottom baffle 3, including:

[0049] The transverse reinforcing bars of the first layer of welded steel mesh are aligned with the side top plate; the longitudinal reinforcing bars of the first layer of welded steel mesh are aligned with the bottom top plate.

[0050] Place the horizontal and vertical reinforcing bars of the second, third, fourth, and so on layers of steel mesh in sequence until the length limit of the positioning reinforcing bars is reached; weld all intersections in sequence, and the batch of steel mesh is completed after welding.

[0051] The preparation method of the reinforcing mesh adopts a mould for welding the reinforcing mesh, and greatly reduces the reinforcing positioning error by accurately adjusting the movable insert plate, thereby ensuring the reinforcing mesh size precision and mesh uniformity, enhancing the overall structure strength and stability of the reinforcing mesh, and improving the welding quality; the flexible adjustment of the position of the movable insert plate enables the same mould to process reinforcing meshes of various specifications, without frequent replacement of the mould, thereby reducing the production cost and time cost; the mould adopts a vertical processing method, thereby reducing the manual operation time and labor intensity, improving the processing efficiency, and meeting the production progress requirements of large-scale construction projects.

[0052] The above merely describes the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
