Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to a horizontal elastic steel bar positioning system and a positioning method. Background Art

[0002] like Figure 1a The steel mesh shown in the figure is widely used in concrete road paving and tunnel lining concrete construction due to its simple structure and low price. The steel mesh is formed by orthogonal arrangement of longitudinal and transverse reinforcements. Figure 1a The vertical reinforcement in the steel mesh is the longitudinal reinforcement 01, and the horizontal reinforcement ( Figure 1a The horizontal direction in the figure is transverse reinforcement 02. When making the steel mesh, the longitudinal reinforcement 01 and the transverse reinforcement 02 need to be connected together by welding the intersections, and the welding equipment used is a welding machine 03. Figure 1b As shown in the schematic diagram of making a steel mesh, the longitudinal reinforcement 01 enters the welding device inside the welding machine through a fixed positioning device 04, and the transverse reinforcement 02 is placed above the longitudinal reinforcement 01 through a loading device (not shown). Finally, the intersection of the transverse reinforcement 02 and the longitudinal reinforcement 01 is welded and connected by resistance pressure welding to achieve the connection between the single transverse reinforcement 02 and the longitudinal reinforcement 01.

[0003] Existing welding machines can only produce single-type steel mesh with smaller steel bar diameters, but for some large steel meshes, such as Figure 1c In the cross-sectional view of a steel mesh shown in FIG. 1 , the diameter of the longitudinal reinforcement is often more than 20 mm. The longitudinal reinforcement is not only arranged in a single form (usually called a single reinforcement 05), but also in a form of two longitudinal reinforcements with different diameters placed side by side to form a parallel reinforcement 06. Parallel reinforcement 06 is usually composed of a longitudinal reinforcement with a larger diameter (usually called a main reinforcement 061) and a longitudinal reinforcement with a smaller diameter (usually called a secondary reinforcement 062) placed side by side, wherein the diameter of the main reinforcement 061 can be equal to the diameter of the single longitudinal reinforcement 05. Due to different design requirements at different positions of the steel mesh, the arrangement form of the longitudinal reinforcement of the same steel mesh also changes with the longitudinal direction of the steel mesh, that is, the arrangement forms of the single reinforcement 05 and parallel reinforcement 06 of the steel mesh are different at different positions. It should be noted that in actual engineering, the positioning device 04 does not need to rise and fall frequently. The existing single positioning method cannot guarantee the positioning of the parallel reinforcement 06, so it is necessary to design a horizontal positioning device for the longitudinal reinforcement of large steel meshes that can adapt to the coexistence of single reinforcement 05 and parallel reinforcement 06 and frequently change.

Therefore, the features defined as "first", "second" and "third" may explicitly or implicitly include one or at least two of the features, unless the content clearly indicates otherwise.

[0037] The invention provides a horizontal elastic steel bar positioning system and positioning method to solve the problem that the prior art cannot simultaneously position single bars and parallel bars.

[0038] like Figure 2a As shown, this embodiment provides a horizontal elastic steel bar positioning system, which includes a first positioning structure 10, a second positioning structure 20, a first telescopic member 31 and a second telescopic member 32; please refer to Figure 2b The first positioning structure 10 includes a first positioning rod 11 and a plurality of first limiting blocks 12, wherein the first positioning rod 11 is arranged in the horizontal direction, and the plurality of first limiting blocks 12 are arranged below the first positioning rod 11 at intervals in the vertical direction, and the first telescopic member 31 is connected to the first positioning structure 10 to drive the first positioning structure 10 to move along the axial direction of the first positioning rod 11; please refer to Figure 2c The second positioning structure 20 includes a second positioning rod 21 and a plurality of limiting components, the second positioning rod 21 is arranged in the horizontal direction, and the plurality of limiting components are arranged in sequence along the axial direction of the second positioning rod 21, and the second telescopic member 32 is connected to the second positioning structure 20 to drive the second positioning structure 20 to move along the axial direction of the second positioning rod 21; continue to refer to Figure 2cEach of the limiting components includes a base 24, an elastic member 23 and a second limiting block 22. The base 24 is fixedly connected to the second positioning rod 21. The second limiting block 22 is movably arranged on the second positioning rod 21 along the axial direction of the second positioning rod 21 and extends downwardly from the second positioning rod. One end of the elastic member 23 is connected to the base 24, and the other end is connected to the second limiting block 22. The elastic member 23 is used to apply an elastic force to the second limiting block 22 in a direction away from the base 24 to push the second limiting block 22 away from the base 24.

[0039] Accordingly, if Figure 3a As shown, this embodiment provides a horizontal elastic steel bar positioning method, which uses the horizontal elastic steel bar positioning system as described above to realize the positioning of multiple steel bars, and the steel bar positioning method includes:

[0040] S1: using the first telescopic member 31 to drive the first positioning structure 10 to move along a first direction until the first limiting block 12 abuts against the steel bar;

[0041] S2: using the second telescopic member 32 to drive the second positioning structure 20 to move in a direction opposite to the first direction until the second limit block 22 abuts against the steel bar.

[0042] It should be understood that the first direction is the direction in which the first stopper 12 approaches the steel bar along the axial direction of the first positioning rod 11, and the opposite direction of the first direction is the direction in which the second stopper 22 approaches the steel bar along the axial direction of the second positioning rod 21. In addition, the first positioning structure 10 and the second positioning structure 20 are arranged at intervals along the axial direction perpendicular to the first positioning rod 11 or the second positioning rod 21. Specifically, Figure 2a and Figure 3b The first direction is specifically the right direction, and the direction opposite to the first direction is specifically the left direction. The first positioning rod 11 extends in the first direction, and the second positioning rod 21 extends in the direction opposite to the first direction. For the convenience of description, the first direction is represented by the right direction, and the direction opposite to the first direction is represented by the left direction. Of course, those skilled in the art can configure the actual meanings of the left direction and the right direction according to the relative positions of the main reinforcement 41 and the secondary reinforcement 42. The first telescopic member 31 drives the first positioning structure 10 to move in the right direction until each main reinforcement 41 abuts against the corresponding first limiting block 12 to complete the left-side positioning of the main reinforcement 41. The second telescopic member 32 drives the second positioning structure 20 to move in the left direction until each reinforcement abuts against the second limiting block 12 to complete the right-side positioning of the main reinforcement 41 and the secondary reinforcement 42.

[0043] Please note that, please refer to Figure 3bIn actual engineering, the cross section of the steel bar is usually circular. The steel bar (i.e., the longitudinal bar of the steel mesh) includes a single steel bar (called a single bar) and does not include two steel bars of different diameters arranged side by side (called parallel bars). The parallel bars include a main bar 41 with a larger diameter and a secondary bar 42 with a smaller diameter. The diameter of the single bar is the same as the diameter of the main bar 41. For ease of description, the single bar is represented by the main bar 41. The single longitudinal bar of the steel mesh is the main bar 41 or a combination of the main bar 41 and the secondary bar 42 arranged adjacently. It should also be noted that when the horizontal elastic steel bar positioning system positions the parallel bars, after the main bar 41 abuts against the first limit block 12 and the secondary bar 42 abuts against the second limit block 22, since the diameter and weight of the main bar 41 are much larger than the diameter and weight of the secondary bar 42, the bottom of the main bar 41 is still flush with the bottom of the secondary bar 42. It is easy to know that when the steel bar is a parallel bar (i.e., the main bar 41 and the secondary bar 42), the elastic member 23 produces a larger deformation (compression) so that the parallel bar abuts against the second limit block 22. When the steel bar is a single bar (i.e., the main bar 41), the elastic member produces a smaller deformation so that the single bar abuts against the second limit block 22. Therefore, it is applicable regardless of whether the steel bar is a single bar or a parallel bar.

[0044] Furthermore, the limiting assembly also includes a guide sleeve 25, which is movably sleeved on the second positioning rod 21 along the axial direction of the second positioning rod 21, and the second limiting block 22 is fixedly connected to the guide sleeve 25; the other end of the elastic member 23 is connected to the second limiting block 22 through the guide sleeve 25. By providing the guide sleeve 25, the friction indirectly generated between the second limiting block 22 and the second positioning rod 21 during the movement can be reduced, so that the second limiting block 22 can move more smoothly. In addition, the second limiting block 22 is welded and fixed to the guide sleeve 25 in the vertical direction. Specifically, the guide sleeve 25 is a cylindrical structure with a perforation, and the second positioning rod 21 is penetrated by the perforation. Of course, the guide sleeve can also have other structures with perforations, such as a square structure, and those skilled in the art can configure it according to actual conditions.

[0045] Going further, continue to refer to Figure 2c The second positioning structure also includes an end limit seat 26, the second positioning rod 21 has a first end 211 and a second end 212 that are opposite to each other along its own axial direction, the second telescopic member 32 is connected to the second end 212, each of the limit components is arranged in the direction of the base 24 close to the second end 212, the end limit seat 26 is fixedly connected to the second positioning rod 21, and is closer to the first end 211 relative to the limit component; the end limit seat 26 is used to limit the displacement of the guide sleeve 25 of the limit component close to the first end 211 toward the first end 211.

[0046] Furthermore, except for the limit assembly near the second end 212, the base 24 in each limit assembly is used to limit the displacement of the guide sleeve of the adjacent limit assembly toward the first end 211, that is, except for the limit assembly near the second end 212, in the other two adjacent limit assemblies, the base in the limit assembly near the first end 211 is used to limit the displacement of the guide sleeve in the limit assembly near the second end. Of course, it should be noted that for all limit assemblies, in the two adjacent limit assemblies near the second end 212, the base in the limit assembly near the first end 211 is used to limit the displacement of the guide sleeve in the limit assembly near the second end 212. In addition, the end limit seat 26 is used to limit the displacement of the guide sleeve in the limit assembly near the first end 211. Specifically, the direction toward the first end 211 is Figure 2c The left direction in the direction toward the second end 212 is Figure 2c Preferably, each guide sleeve abuts against the adjacent base, the guide sleeve near the first end 211 abuts against the end stop seat 26, and the compression amount of the elastic member 23 is at least zero, so that after the second positioning structure 20 releases the positioning of the steel bar, the guide sleeve 25 and the second stop block 22 connected thereto can return to the initial position under the action of the elastic member 23.

[0047] Furthermore, a plurality of the first limiting blocks 12 are evenly spaced apart along the axial direction of the first positioning rod 11 ; and a plurality of the bases of the limiting assemblies are evenly spaced apart along the axial direction of the second positioning rod 21 .

[0048] Furthermore, the spacing between two adjacent bases 24 is not less than the spacing between two adjacent first limit blocks 12, so as to avoid the spacing between two adjacent second limit blocks 22 being less than the spacing between two adjacent first limit blocks 12, resulting in the elastic member 23 not generating deformation and making it impossible to position the steel bar. And the spacing between two adjacent bases 24 is not more than 1.5 times the spacing between two adjacent first limit blocks 12, so as to avoid the number of steel bars between two adjacent second limit blocks 22 being more than one during positioning. Optionally, before the second positioning structure 20 positions the steel bar, the compression amount of the elastic member 23 is zero, and the spacing between two adjacent second limit blocks 22 is the length of the elastic member 23 in the natural state. In actual engineering, the elastic member 23 is generally a spring, and the base 24 is a spring seat, and is sleeved on the second positioning rod 21 along the axial direction of the second positioning rod 21.

[0049] Furthermore, the number of the second limiting blocks 22 is equal to the number of the first limiting blocks 12 .

[0050] Preferably, the first limiting block 12 and the first positioning rod 11 are formed integrally.

[0051] In an exemplary embodiment, the first telescopic member 31 and the second telescopic member 32 include hydraulic cylinders or air cylinders, respectively.

[0052] Optionally, the steel bar positioning method further comprises:

[0053] Before using the first telescopic member 31 to drive the first positioning structure 10 to move in the first direction, the axial position of the first limit block 12 along the first positioning rod 11 is set to match the axial position of the steel bar along the first positioning rod 11, that is, the first positioning structure 10 is moved so that a steel bar is evenly distributed between two adjacent first limit blocks 12; before using the second telescopic member 32 to drive the second positioning structure 20 to move in a direction opposite to the first direction, the axial position of the second limit block 22 along the second positioning rod 21 is set to match the axial position of the steel bar along the second positioning rod 21, that is, the second positioning structure 20 is moved so that a steel bar is evenly distributed between two adjacent second limit blocks 22.

[0054] After the first limiting block 12 and the second limiting block 22 are both against the steel bar, the steel bar positioning method further includes:

[0055] Using the second telescopic member 32 to drive the second positioning structure 20 away from the steel bar along the first direction, so as to release the second positioning structure 20 from positioning the steel bar;

[0056] The first telescopic member 31 is used to drive the first positioning structure 10 away from the steel bar in a direction opposite to the first direction, so as to release the first positioning structure 10 from positioning the steel bar.

By setting a first positioning structure and driving the first positioning structure to move to the steel bar against the first limiting block, the position of multiple steel bars on the same side in the horizontal direction can be limited, and by setting a second positioning structure and driving the second positioning structure to move to the steel bar against the second limiting block, the position of multiple steel bars on the other side in the horizontal direction can be limited, thereby, each steel bar is respectively against the first limiting block and the second limiting block, thereby realizing the positioning of the steel bar.
