Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to a vertical 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] The existing welding machine can only produce a single type of steel mesh with a small steel bar diameter, 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 arranged in a form of two longitudinal reinforcements with different diameters placed side by side to form a parallel reinforcement 06. The 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 of the longitudinal reinforcement of the same steel mesh also changes with the longitudinal direction of the steel mesh, that is, at different positions, the arrangement of the single reinforcement 05 and the parallel reinforcement 06 of the steel mesh is different, and when the steel mesh is welded, the positioning device 04 needs 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 a large steel mesh that can adapt to the coexistence of single reinforcement 05 and parallel reinforcement 06 and frequently changes.

[0041] The invention provides a vertical elastic steel bar positioning system and positioning method to solve the problem that the prior art cannot simultaneously position single bars and parallel bars.

[0042] like Figure 2a As shown, this embodiment provides a vertical elastic steel bar positioning system, which includes a first positioning structure 10, a second positioning structure 20, a first telescopic member 31, a second telescopic member 32 and a third telescopic member 33; 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 second limit blocks 22, the second positioning rod 21 is arranged in the horizontal direction, and the plurality of second limit blocks 22 are arranged at intervals below the second positioning rod 21 in the vertical direction, the second telescopic member 32 is connected to the second positioning structure 20 to drive the second positioning structure 20 to move axially along the second positioning rod 22, and the third telescopic member 33 is connected to the second positioning structure 20 to drive the second positioning structure 20 to move in the vertical direction; each second limit block 22 includes a main limit block 221 and a sub-limit block 222 arranged adjacent to each other along the axial direction of the second positioning rod 21, the main limit block 221 is fixedly connected to the second positioning rod 21, and the sub-limit block 222 is movably connected to the second positioning rod 21 in the vertical direction through an elastic member 23.

[0043] Accordingly, if Figure 3a As shown, this embodiment provides a vertical elastic steel bar positioning method, which uses the vertical elastic steel bar positioning system as described above to realize the positioning of multiple steel bars, and the vertical elastic steel bar positioning method includes:

[0044] 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;

[0045] S2: using the third telescopic member 33 to drive the second positioning structure 20 to move in the vertical direction until the bottom of the main limit block 221 is at least downwardly beyond the maximum horizontal width of the steel bar;

[0046] S3: 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.

[0047] 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. It should be noted that please refer to Figure 3b and Figure 3c In actual engineering, the steel bars (i.e., the longitudinal bars of the steel mesh) include a single steel bar (called a single bar) and 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 that 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.

[0048] In the vertical elastic steel bar positioning system and positioning method, by setting the first positioning structure 10 and driving the first positioning structure 10 to move along the first direction until each first limit block 12 abuts against the corresponding steel bar, the positions of multiple steel bars on the same side along the horizontal direction can be limited ( Figure 2a By setting a second positioning structure 20 and driving the second positioning structure 20 to move in a direction opposite to the first direction until each second limit block 22 abuts against the corresponding steel bar, the position of multiple steel bars on the other side along the horizontal direction can be limited ( Figure 2bThe right side of the steel bar in the middle) is used to realize the positioning of the steel bar. Before driving the second positioning structure 20 to move in a direction opposite to the first direction, by setting the second limit block 22 of the second positioning structure to include a sub-limit block 222, and driving the second positioning structure 20 to move downward in the vertical direction to the bottom of the main limit block 221 at least exceeding the height of the maximum horizontal width of the steel bar, the position of the secondary reinforcement in the steel bar in the vertical direction can be limited. As a result, each steel bar abuts against the first limit block and the second limit block on both sides along the horizontal direction, thereby realizing the positioning of the steel bar. It should be understood that the maximum horizontal width of the steel bar refers to the maximum radial dimension of the main reinforcement 41 along the horizontal direction. Usually, the cross-section of the main reinforcement 41 is circular, which is its horizontal diameter. Please continue to refer to Figure 3c When the steel bars are parallel, the second positioning structure 20 is driven to move vertically until the sub-limit block 222 just abuts against the steel bar, and then the second positioning structure 20 is driven to move until the main limit block 221 moves to a height that is at least greater than the diameter of the steel bar ( Figure 3c and Figure 3f In the embodiment, the bottom of the main stopper 221 is just flush with the bottom of the steel bar) to compress the secondary reinforcement 42 and enable the main stopper 221 to abut against the side of the secondary reinforcement 42. In this configuration, when the steel bar is parallel reinforcement, the main stopper 221 abuts against the side of the secondary reinforcement 42, and the sub-stopper 222 abuts against the side of the main reinforcement 41, thereby limiting the parallel reinforcement. Of course, when the steel bar is a single reinforcement, the sub-stopper 222 is used to abut against the main reinforcement 41; or it can be understood that the steel bar is within the range of the main stopper 221 in the vertical direction, so it is applicable regardless of whether the steel bar is a single reinforcement or parallel reinforcement.

[0049] More specifically, please refer to Figure 3d~3f , Figure 3d~3f 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 along the first direction, and the second positioning rod 21 extends along 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 rib 41 and the auxiliary rib 42. Figure 3d , the first telescopic member 31 drives the first positioning structure 10 to move rightward until each main rib 41 abuts against the corresponding first limiting block 12 to complete the left side positioning of the main rib 41; Figure 3d When the steel bar is parallel, the third telescopic member 33 drives the second positioning structure 20 to move downward until the sub-limit block 222 abuts against the secondary reinforcement 42, and the bottom of the main limit block 22 at least exceeds the bottom of the steel bar to complete the vertical positioning of the secondary reinforcement; Figure 3fThe second telescopic member 32 drives the second positioning structure 20 to move leftward until each steel bar abuts against the second limiting block 12, so as to complete the right positioning of the main reinforcement 41 and the secondary reinforcement 42. Specifically, for a single reinforcement, the main reinforcement 41 abuts against the sub-limiting block 222, and for a parallel reinforcement, the secondary reinforcement 42 abuts against the main limiting block 221. Thus, the positioning of a single reinforcement or a parallel reinforcement is achieved.

[0050] Optionally, a plurality of the first stop blocks 12 are evenly spaced along the axial direction of the first positioning rod 11, a plurality of the second stop blocks 22 are evenly spaced along the axial direction of the second stop rod 21, and the spacing between two adjacent first stop blocks 12 is equal to the spacing between two adjacent second stop blocks 22. With such a configuration, the longitudinal bars of the produced steel mesh can be evenly arranged.

[0051] Preferably, the number of the second limiting blocks 22 is equal to the number of the first limiting blocks 12 .

[0052] Further, the vertical elastic steel bar positioning system includes at least two third telescopic members 33, and at least two third telescopic members 33 are arranged at intervals along the axial direction of the second positioning rod. In addition, at least three third telescopic members 33 divide the rod body of the second positioning rod 21 provided with multiple second limit blocks 22 into at least three parts. At least two third telescopic members 33 are provided so that the second positioning structure 20 is evenly compressed when moving downward in the vertical direction. For at least three third telescopic members 33, they are evenly arranged at intervals along the axial direction of the second positioning rod 21, and at least three third telescopic members 33 divide the rod body of the second positioning rod 21 provided with multiple second limit blocks 22 into at least two parts or at least four parts.

[0053] Further, refer to Figure 2d The main limit block 221 has a slide groove 2210 opened in the vertical direction, and the sub-limit block 222 is movably arranged in the slide groove 2210. Such a configuration reduces the friction between the sub-limit block 222 and the main limit block 221 during the movement, so that the sub-limit block 222 can move in the vertical direction more effectively and conveniently.

[0054] Furthermore, the length of the slide groove 2210 along the vertical direction is not less than the length of the main limit block 221 along the vertical direction ( Figure 2d The main limit block 221 has not exceeded the bottom of the main rib 41, and the sub-limit block 222 has abutted against the top of the slide slot 220. Specifically, the slide slot 2210 passes through the bottom of the main limit block 221, and the distance between the slide slot 2210 and the top of the main limit block 221 or the top of the slide slot 2210 and the top of the main limit block 221 does not exceed 3 / 1 of the length of the main limit block 221 in the vertical direction. The slide slot 2210 is along the axial direction ( Figure 2d The depth of the sub-limit block 222 in the vertical direction is not greater than 1 / 4 of the axial length of the second positioning rod, so as to avoid the slide groove 2210 being too deep, resulting in most of the sub-limit block 222 being located in the slide groove 2210, affecting the positioning of the secondary reinforcement.

[0055] Furthermore, when the elastic member 23 is not subjected to external force, the bottom of the sub-limit block 222 is flush with the bottom of the main limit block 221, or the bottom of the sub-limit block 222 extends downward beyond the bottom of the main limit block 221. In this way, when the second positioning structure 20 is driven to move downward, part of the elastic member 23 generates sufficient deformation to vertically position the secondary rib. Preferably, the elastic member 23 is a spring.

[0056] Preferably, the first limiting block 12 is formed integrally with the first positioning rod 11 , and the main limiting block 221 is formed integrally with the second positioning rod 21 .

[0057] In an exemplary embodiment, the first telescopic member 31 , the second telescopic member 32 and the third telescopic member 33 respectively include hydraulic cylinders or air cylinders.

[0058] Optionally, the vertical elastic steel bar positioning method further comprises:

[0059] Before the third telescopic member 33 is used to drive the second positioning structure 20 to move in the vertical direction, the axial position of the sub-limit block 222 along the second positioning rod 21 is set to match the axial position of the steel bar along the second positioning rod. Figure 3d That is, when the vertical elastic steel bar positioning system positions the steel bars, the distance between the center axis of the sub-limit block 222 and the center of the secondary reinforcement 42 is set within the engineering requirements, thereby increasing the contact area between the bottom of the sub-limit block 222 and the secondary reinforcement 42, avoiding affecting the vertical positioning of the secondary reinforcement 42.

[0060] After the first limiting block 12 and the second limiting block 22 are both against the steel bar, the vertical elastic steel bar positioning method further includes:

[0061] Using the first telescopic member 11 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;

[0062] The third telescopic member 33 is used to drive the second positioning structure 20 away from the steel bar in the vertical direction, and then the second telescopic member 32 is used to drive the second positioning structure 20 away from the steel bar in the first direction to release the second positioning structure 20 from positioning the steel bar.

[0063] In summary, in the vertical elastic steel bar positioning system and positioning method provided by the present invention, the vertical elastic steel bar positioning system includes a first positioning structure, a second positioning structure, a first telescopic member, a second telescopic member and a third telescopic member; the first positioning structure includes a first positioning rod and a plurality of first limit blocks, the first positioning rod is arranged in a horizontal direction, and a plurality of first limit blocks are arranged below the first positioning rod at intervals along the axial direction of the first positioning rod, the first telescopic member is connected to the first positioning structure to drive the first positioning structure to move along the axial direction of the first positioning rod; the second positioning structure includes a second positioning rod and a plurality of second limit blocks, the The second positioning rod is arranged in the horizontal direction, and a plurality of the second limiting blocks are arranged below the second positioning rod at intervals along the axial direction of the second positioning rod, the second telescopic member is connected to the second positioning rod structure to drive the second positioning structure to move along the axial direction of the second positioning rod, and the third telescopic member is connected to the second positioning structure to drive the second positioning structure to move along the vertical direction; each of the second limiting blocks includes a main limiting block and a sub-limiting block arranged adjacent to each other along the axial direction of the second positioning rod, the main limiting block is fixedly connected to the second positioning rod, and the sub-limiting block is movably connected to the second positioning rod in the vertical direction by an elastic member. By setting the first positioning structure and driving the first positioning structure to move to the steel bar against the first limiting block, the positions of the plurality of steel bars on the same side in the horizontal direction can be limited, and by setting the second positioning structure and driving the second positioning structure to move to the steel bar against the second limiting block, the positions of the plurality of 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. Furthermore, by setting the second limit block of the second positioning structure to include a sub-limit block, and by using the third telescopic member, the position of the secondary reinforcement in the steel bar in the vertical direction can be limited. The vertical elastic steel bar positioning system has a simple structure, a high degree of automation and strong adaptability in practical applications.
