Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a steel bar positioning frame for the construction of exterior shear walls. Background Technique

[0002] During the installation of precast shear walls, since the steel bars of the shear walls were not positioned during the pouring of the lower-layer concrete, before installing the precast shear walls, it is necessary to reposition and adjust the steel bars. This makes the installation and adjustment process of the precast shear walls complex and difficult. Once the steel bars are severely displaced, the steel bars must be cut and re-implanted, which has a greater impact on the structure of the precast shear walls. The positioning and adjustment of the steel bars will not only affect the construction progress of the building, but also pose a greater potential safety hazard to the structure of the precast shear walls.

[0003] Combining the above problems, it can be found that when the existing steel bar positioning frames on the market are in use, it is very difficult to avoid the above-mentioned problems at the same time. And even if these problems can be solved, external tools need to be used in cooperation to solve them, thus failing to achieve the desired effect.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Please refer to Figures 1-11 , the present invention provides a technical solution: a steel bar positioning frame for external shear wall construction, including a positioning frame assembly 1, a fixing assembly 2 and an A positioning assembly 3 are arranged at the upper end of the positioning frame assembly 1, and a driving assembly 4 is arranged at the side end of the positioning frame assembly 1.

[0022] The positioning frame assembly 1 includes a main body part 11, the main body part 11 is arranged in a mouth-shaped structure, and an extrusion groove 13 is opened inside it, a sliding groove 14 is opened in the extrusion groove 13, and a plurality of B positioning assemblies 5 are slidably connected in the sliding groove 14, and a steel wire rope 12 is slidably sleeved on the surfaces of the plurality of B positioning assemblies 5.

[0023] The B positioning assembly 5 includes a sliding part 511, the sliding part 511 is slidably connected in the sliding groove 14, a slide block 52 is slidably connected to the surface of the sliding part 511, one end of the slide block 52 is fixedly connected to a rack 55, and the rack 55 penetrates and extends out of the surface of the sliding part 511, one end of the sliding part 511 is fixedly connected to a mounting plate 513, a bi-directional screw rod 57 is rotatably connected to the mounting plate 513, two B clamping parts 58 are threadedly connected to the surface of the bi-directional screw rod 57, and the two B clamping parts 58 are symmetrically arranged, a gear 56 is fixedly connected to the surface of the bi-directional screw rod 57, the gear 56 meshes with the rack 55, the steel wire rope 12 is slidably sleeved on the plurality of slide blocks 52, and a rebound part 59 is fixedly connected between the sliding part 511 and the slide block 52.

[0024] Specifically, during the casting of shear wall concrete in building construction, in order to prevent the vertical steel bars from deforming during casting and thus affecting the overall strength of the shear wall, the positioning frame assembly 1 can be fixed to the upper formwork through the fixing assembly 2 first. Since the main body 11 is internally provided with an extrusion groove 13, and a sliding groove 14 is provided inside the extrusion groove 13, a plurality of sliding parts 511 are slidably connected to the sliding groove 14, and a slider 52 is slidably connected to the surface of the sliding part 511. One end of the slider 52 is fixedly connected to a rack 55, and the rack 55 penetrates and extends out of the surface of the sliding part 511. The rack 55 meshes with a gear 56, and a bidirectional screw 57 is fixedly connected inside the gear 56. Two B clamping parts 58 are threadedly connected to the bidirectional screw 57, and the B clamping parts 58 are slidably connected to the side end of the sliding part 511. At this time, a steel wire rope 12 is slidably sleeved on the surfaces of the plurality of sliders 52. By tightening the steel wire rope 12, the slider 52 can be driven to slide, and then the rack 55 can be pushed to move, and then the gear 56 can be driven to rotate, so that the two B clamping parts 58 can be closed, so as to position the vertical steel bars. And during use, after the two B clamping parts 58 completely clamp the steel bars, the rack 55 will not contact the steel bars, thus avoiding the situation that the steel bars cannot be positioned due to the movement of the rack 55. The vertical steel bars close to the four inner walls inside the main body 11 can be simultaneously positioned through the plurality of B positioning components 5. And during use, the driving assembly 4 can be used to tighten the steel wire rope 12, so as to control the B positioning components 5 to perform the positioning operation on the vertical steel bars.

[0025] Further, the upper formwork refers to the formwork of the main part of the shear wall, which is assembled by aluminum alloy, wooden formwork or steel formwork, and forms an overall stiffness through back ribs such as 60×30 rectangular steel pipes or channel steel and horizontal reinforcement screws. The width of the formwork is usually a standard specification of 400mm, and supplemented with patch formwork of different widths to adapt to the change of wall size.

[0026] As a further limitation of the B positioning component 5 of the present invention, the B positioning component 5 further includes an extrusion part 512. The extrusion part 512 is fixedly connected to one end of the sliding part 511. A pressure groove 510 is provided on the surface of the extrusion part 512, and a chamfer is provided at one end of the pressure groove 510. A pressure block 53 is fixedly connected to the surface of the slider 52, and the pressure block 53 is slidably connected to the pressure groove 510.

[0027] Specifically, during use, in order to enable the sliding part 511 to fix the position of the main body part 11 during the movement of the slider 52, the extrusion part 512 is fixedly connected to one end of the sliding part 511. A pressure groove 510 is formed on the surface of the extrusion part 512, and a chamfer is provided at the end of the pressure groove 510 close to the sliding part 511. A pressure block 53 is arranged on the surface of the slider 52, and the pressure block 53 is slidably connected in the pressure groove 510. Since the pressure block 53 is arranged in a trapezoidal structure, when the slider 52 moves towards the sliding part 511, the pressure block 53 can be driven to extrude the hypotenuse of the pressure groove 510. Since the extrusion part 512 is made of a rigid material with a certain elasticity and the end of the extrusion part 512 is connected to the sliding part 511, the extrusion part 512 can be extruded to deform it, and then the extrusion part 512 can be extruded in the up and down directions, so that the extrusion part 512 can abut against the extrusion groove 13 up and down, and then the sliding part 511 can be fixed at this position.

[0028] As a further limitation of the B positioning assembly 5 of the present invention, the B positioning assembly 5 further includes a baffle 54. The baffle 54 is fixedly connected to one end of the sliding part 511, and there are two baffles 54. The mounting plate 513 and the two B clamping members 58 are both arranged between the two baffles 54.

[0029] Specifically, in order to prevent the B clamping member 58 from deforming or shifting during the positioning of the steel bar by the B clamping member 58, baffles 54 can be arranged above and below the B clamping member 58, and the baffles 54 are fixedly connected to one end of the sliding part 511, so as to limit and protect the B clamping member 58.

[0030] The specific implementation manner of this embodiment is as follows: when positioning the vertical steel bar, the position of the main body part 11 can be fixed first, and then a single vertical steel bar is arranged between the two B clamping members 58, and multiple vertical steel bars are arranged on multiple B positioning assemblies 5. Then, by pushing the steel wire rope 12 on one side inward, when the steel wire rope 12 on this side is pushed, the other three sides of the steel wire rope 12 will tighten inward accordingly, so that the sliding part 511 can be fixed in position, and the B clamping member 58 can be driven to move, and then the vertical steel bar between the two B clamping members 58 can be positioned, thus realizing the rapid positioning of the vertical steel bar.

[0031] Embodiment 2: Please refer to Figures 1-11, the present invention provides a technical solution: The driving component 4 includes an A screw 41, a B screw 42, and a driving member 43. The driving member 43 is slidably connected within the main body member 11, and the driving member 43 is fixedly connected to the steel wire rope 12. Both the A screw 41 and the B screw 42 are rotatably connected to one end of the driving member 43. Two threaded holes are provided at the side end of the main body member 11, and the A screw 41 and the B screw 42 are respectively threadedly connected within the two threaded holes. Two fitting members 15 are fixedly connected within the extrusion groove 13, and the length of the driving member 43 is slightly less than the distance between the two fitting members 15.

[0032] Specifically, when tightening the steel wire rope 12, the steel wire rope 12 can be fixedly connected to the driving member 43. The A screw 41 and the B screw 42 are respectively rotatably connected to both ends on the same side of the driving member 43. Both the A screw 41 and the B screw 42 are threadedly connected to the main body member 11. At this time, by simultaneously rotating the A screw 41 and the B screw 42, the driving member 43 can be pushed to move. Since two fitting members 15 are fixedly connected within the extrusion groove 13, and the length of the driving member 43 is less than the distance between the two fitting members 15, the driving member 43 can move between the two fitting members 15. And since the steel wire rope 12 is slidably sleeved on the surfaces of the two fitting members 15, during use, since the three sides of the steel wire rope 12 are sleeved on a plurality of sliders 52, the three sides of the steel wire rope 12 are limited. Since the total length of the steel wire rope 12 remains unchanged, by pushing the other side to tighten, the other three sides can be driven to tighten. And subsequently, the slider 52 can be pushed by the elastic member 59, and through the slider 52, the steel wire rope 12 can be reset, and further, the B clamping member 58 can be made to no longer position the vertical steel bar. When it is necessary to push the steel wire rope 12, the driving member 43 can be pushed to move, thereby driving the contact end of the steel wire rope 12 and the driving member 43 to move towards the inner wall of the main body member 11. Since the perimeter of the steel wire rope 12 remains fixed, when one side of the steel wire rope 12 moves inward, the other three sides of the steel wire rope 12 will be simultaneously driven to tighten inward. And since the steel wire rope 12 is slidably sleeved on a plurality of B positioning components 5, at this time, one side of the steel wire rope 12 moves inward, and thus the other three sides of the steel wire rope 12 can be driven to contract inward, thereby pushing the slider 52 to move.

[0033] As a further limitation of the driving component 4 of the present invention, the driving component 4 further includes a synchronous arm 44 and an extension member 45. Extension members 46 are fixedly connected to the surfaces of both the A screw 41 and the B screw 42. There are two extension members 45, and the two extension members 45 are respectively rotatably connected to one end of the two extension members 46. The synchronous arm 44 is fixedly connected to the surfaces of the two extension members 45.

[0034] Specifically, in order to drive the A screw rod 41 and the B screw rod 42 to rotate simultaneously, extension members 46 can be fixedly connected to the surfaces of the A screw rod 41 and the B screw rod 42, and expansion members 45 are rotatably connected to the extension members 46. Synchronization arms 44 are fixedly connected to the surfaces of the two expansion members 45. By rotating the synchronization arms 44, the A screw rod 41 and the B screw rod 42 can be driven to rotate synchronously.

[0035] As a further limitation of the driving assembly 4 of the present invention, the driving member 43 is arranged in a trapezoidal structure, and a fixing groove is formed at the end of the driving member 43. The steel wire rope 12 is fixedly connected in the fixing groove.

[0036] Specifically, during use, since the steel wire rope 12 on this side will move inward, in order to enable multiple sliders 52 arranged on this side to move simultaneously, the driving member 43 can be used to push two sliders 52 at the same side end to move. Since a notch is formed on the surface of the slider 52, in order to enable the driving member 43 to be inserted into the notch, the driving member 43 can be arranged in a trapezoidal structure, and a fixing groove can be formed at the end of the driving member 43. The steel wire rope 12 is arranged in the fixing groove, so that the steel wire rope 12 can maintain a stable connection with the driving member 43 during tightening.

[0037] The specific implementation manner of this embodiment is as follows: In order to enable the steel wire rope 12 to be tightened stably when positioning the vertical steel bars, a driving assembly 4 can be arranged on the main body member 11 at this time. A part of the steel wire rope 12 is connected to the driving member 43, and the A screw rod 41 and the B screw rod 42 are arranged on the driving member 43. The two are threadedly connected to the main body member 11, and the A screw rod 41 and the B screw rod 42 are linked through the synchronization arm 44. At this time, by rotating the synchronization arm 44, the A screw rod 41 and the B screw rod 42 can be driven to rotate together. Through the synchronous rotation of the two, the driving member 43 can be pushed to move, and then the steel wire rope 12 can be driven to be tightened efficiently. Further, the slider 52 can be driven to move, and through the movement of the slider 52, the extrusion part 512 can be driven to squeeze the extrusion groove 13 up and down simultaneously, so that the position of the sliding part 511 can be fixed. At this time, the vertical steel bars can be clamped by two B clamping members 58, so as to position the vertical steel bars.

[0038] Embodiment 3: Please refer to Figures 1-11 , the present invention provides a technical solution: The A positioning assembly 3 includes a connecting member 31 and a positioning plate 32.

[0039] Specifically, when positioning multiple vertical steel bars arranged inside the main body member 11, a connecting member 31 can be fixedly connected to the upper end of the main body member 11, a positioning plate 32 can be fixedly connected to the lower end of the connecting member 31, and a plurality of insertion grooves 37 are formed on the surface of the positioning plate 32. The vertical steel bars are arranged inside the insertion grooves 37, so that the multiple vertical steel bars can be positioned.

[0040] As a further limitation of the A positioning assembly 3 of the present invention, the A positioning assembly 3 includes a plurality of disassembly members 33, A clamping members 34 and springs 35. The plurality of disassembly members 33 are respectively slidably connected inside the insertion grooves 37. There are two A clamping members 34, and both of the two A clamping members 34 are slidably connected to the lower ends of the disassembly members 33. The spring 35 is fixedly connected between the two A clamping members 34.

[0041] Specifically, in order to stably position the vertical steel bars, the disassembly members 33 can be detachably connected inside the insertion grooves 37, and two A clamping members 34 are slidably connected to the lower ends of each disassembly member 33. The spring 35 is fixedly connected between the two A clamping members 34. By arranging the steel bars between the two A clamping members 34 and then snapping the A clamping members 34 into the insertion grooves 37, the two A clamping members 34 will approach each other at this time, so that the vertical steel bars can be positioned. Multiple groups of disassembly members 33, A clamping members 34 and springs 35 can be arranged according to different numbers of vertical steel bars.

[0042] As a further limitation of the A positioning assembly 3 of the present invention, limiting plates 36 are arranged at both side ends of the disassembly member 33, and the sum of the lengths of the limiting plates 36 and the disassembly member 33 is greater than the length of the insertion groove 37.

[0043] Specifically, in order to facilitate the removal of the disassembly member 33 after the subsequent pouring is completed, limiting plates 36 can be arranged at the ends of the disassembly member 33. After the disassembly member 33 is arranged inside the insertion groove 37, when the disassembly member 33 needs to be removed, the staff can hold the limiting plates 36 by hand to move the disassembly member 33 upward, thereby facilitating the removal of the disassembly member 33. In order to prevent the limiting plates 36 from being stuck in the insertion groove 37 and causing inconvenience in subsequent removal, the sum of the lengths of the limiting plates 36 and the disassembly member 33 is greater than the length of the insertion groove 37.

[0044] As a further limitation of the fixing assembly 2 of the present invention, the fixing assembly 2 includes a fixing plate 21 and telescopic members 22. There are a plurality of telescopic members 22, and the plurality of telescopic members 22 are all fixedly connected to the upper end of the main body member 11. The fixing plate 21 is fixedly connected to the telescopic ends of the plurality of telescopic members 22.

[0045] Specifically, when fixing the main body part 11, in order to enable the main body part 11 to be stably fixed on the upper template surface, a telescopic part 22 can be arranged at the upper end of the main body part 11, and a fixing plate 21 is fixedly connected to the telescopic end of the telescopic part 22. At this time, the main body part 11 can be stably arranged by detachably connecting the fixing plate 21 and the upper template. When in use, when positioning the steel bars, the height of the main body part 11 can be controlled by controlling the telescopic movement of the telescopic part 22, so as to facilitate the setting of the vertical steel bars on the B positioning component 5.

[0046] The specific implementation manner of this embodiment is as follows: When positioning multiple vertical steel bars inside the main body part 11, an A positioning component 3 can be arranged at the upper end of the main body part 11, and multiple vertical steel bars are arranged on the A positioning component 3, so as to realize the simultaneous positioning of multiple steel bars. When fixing the main body part 11, in order to facilitate the subsequent positioning of the steel bars, a fixing component 2 can be arranged on the main body part 11. The main body part 11 can be stably connected to the upper template through the fixing component 2, and the height of the main body part 11 can be controlled, so as to facilitate the subsequent setting of the steel bars.
