Description
Technical Field
[0001] This utility model relates to the field of steel reinforcement technology in building construction, and specifically to a steel reinforcement positioning structure for building construction. Background Technology
[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site of construction work is called a "construction site" or "building site." During construction, it is common to use tying wire to bind reinforcing bars. This process typically requires workers to hold the reinforcing bars while others secure them, resulting in high workloads and a significant investment of human resources.
[0003] A search revealed that publication number CN218814748U discloses a rebar positioning structure for building construction, including a support plate. Two pillars are fixed to the top of the support plate, and a crossbar is fixed between the two pillars. Each pillar has a sliding seat, and a support rod is fixed between the two sliding seats. The side walls of the crossbar and the support rod are marked with graduations. Multiple rebar support seats are fitted onto both the crossbar and the support rod. Multiple limiting bolts are provided on one side of both the crossbar and the support rod. Each rebar support seat has a screw hole adapted to the limiting bolt. A connecting rod and two locking bolts are provided above both the crossbar and the support rod. Multiple locking blocks are fixed to the bottom of both connecting rods. A groove is provided at the top of each rebar support seat. Two through holes adapted to the locking bolts are provided on both connecting rods, and two screw holes adapted to the locking bolts are provided on both the support rod and the crossbar. The existing rebar positioning structure is easy to adjust and support; however, it has a drawback: when positioning rebar, the device uses clamps to limit the rebar's position, and when faced with multiple sets of rebar of different specifications, it cannot clamp them all at once and can only operate them in batches. Therefore, it is particularly important to improve the existing positioning structure and design a new type of rebar positioning structure to solve the above-mentioned technical defects and improve the overall practicality of the positioning structure. Utility Model Content
[0004] The purpose of this utility model is to provide a rebar positioning structure for building construction. When the clamping block comes into contact with the rebar, the clamping groove also comes into contact with the rebar. Through the "V" shaped structure design of the clamping groove, the rebar can be positioned. When the clamping block is displaced to a designated position, the self-locking property between the worm gear and worm can limit the clamping block, enabling the clamping block to position and clamp the rebar. Moreover, it can position and clamp multiple sets of rebars of different specifications, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A rebar positioning structure for building construction includes a movable frame body, a first connecting frame fixedly connected inside the movable frame body, a second connecting frame slidably connected inside the movable frame body and above the first connecting frame, and multiple sets of positioning components slidably connected to the outer sides of both the first and second connecting frames.
[0007] The positioning component is used to position the reinforcing bars. The positioning component consists of a connecting frame, a rotating block, and two sets of clamping blocks. The connecting frame is slidably connected to the top of the first connecting frame or the second connecting frame. The rotating block is rotatably connected to the inside of the connecting frame. The two sets of clamping blocks are slidably connected to both ends of the connecting frame, respectively.
[0008] As a preferred embodiment of this utility model, the rotating block has two sets of guide grooves at one end near the clamping block, and the guide grooves are designed with an arc-shaped structure.
[0009] As a preferred embodiment of this utility model, a guide rod is fixedly connected to one end of the clamping block near the rotating block, and the clamping block is connected to the guide groove through the guide rod, wherein the guide rod and the guide groove are slidably connected.
[0010] As a preferred embodiment of this utility model, the clamping block has a clamping groove inside for positioning the reinforcing bar, and the clamping groove has a "V" shaped structure design.
[0011] As a preferred embodiment of this utility model, a transmission rod is fixedly connected to the end of the rotating block away from the clamping block, a worm gear is fixedly connected to the outer side of the transmission rod, a worm is meshed with the outer side of the worm gear, and the end of the worm away from the worm gear extends to the outer side of the connecting frame.
[0012] As a preferred embodiment of this utility model, a connecting rod is slidably connected to the bottom of the connecting frame, the connecting rod extends into the interior of the connecting frame and is fixedly connected to a limit rod, a connecting ring is fixedly connected to the outside of the connecting rod, and a compression spring is sleeved on the outside of the connecting ring and located outside the connecting rod.
[0013] As a preferred embodiment of this utility model, the first connecting frame and the second connecting frame each have multiple sets of fixing slots inside, and both the first connecting frame and the second connecting frame are connected to the limiting rod through the fixing slots. The second connecting frame is connected to the main body of the movable frame through a drive screw.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] In this invention, the positioning component is designed so that when the clamping block comes into contact with the rebar, the clamping groove comes into contact with the rebar. The "V" shaped structure of the clamping groove enables the rebar to be positioned.

It can also position and clamp multiple sets of rebars of different specifications. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Example:
[0024] Please see Figures 1-5 This utility model provides a technical solution:
[0025] A rebar positioning structure for building construction includes a movable frame body 1, a first connecting frame 2 fixedly connected inside the movable frame body 1, a second connecting frame 3 slidably connected inside the movable frame body 1 and above the first connecting frame 2, and multiple sets of positioning components 4 slidably connected to the outer sides of both the first connecting frame 2 and the second connecting frame 3.
[0026] The positioning component 4 is used to position the reinforcing bars. The positioning component 4 consists of a connecting frame 5, a rotating block 6, and two sets of clamping blocks 7. The connecting frame 5 is slidably connected to the top of the first connecting frame 2 or the second connecting frame 3. The rotating block 6 is rotatably connected to the inside of the connecting frame 5. The two sets of clamping blocks 7 are slidably connected to both ends of the connecting frame 5.
[0027] Furthermore, the rotating block 6 has two sets of guide grooves 8 at one end near the clamping block 7. The guide grooves 8 are designed with an arc shape. A guide rod is fixedly connected to one end of the clamping block 7 near the rotating block 6. The clamping block 7 is connected to the guide groove 8 through the guide rod. The guide rod and the guide groove 8 are slidably connected. When the rotating block 6 rotates, it drives the guide groove 8 to rotate, causing the guide rod to move and thus driving the clamping block 7 to move.
[0028] Secondly, the clamping block 7 has a clamping groove 9 inside for positioning the reinforcing bar. The clamping groove 9 has a "V" shaped structure design. When the clamping block 7 comes into contact with the reinforcing bar, the clamping groove 9 comes into contact with the reinforcing bar. Through the "V" shaped structure design of the clamping groove 9, the reinforcing bar can be clamped and positioned.
[0029] Furthermore, a transmission rod 10 is fixedly connected to the end of the rotating block 6 away from the clamping block 7. A worm gear 11 is fixedly connected to the outer side of the transmission rod 10. A worm 12 is meshed with the outer side of the worm gear 11. The end of the worm 12 away from the worm gear 11 extends to the outer side of the connecting frame 5. Rotating the worm 12 drives the worm gear 11 to rotate, causing the transmission rod 10 to rotate, which in turn drives the rotating block 6 to rotate, causing the guide groove 8 to rotate. When the clamping block 7 is moved to the designated position, the self-locking property between the worm gear 11 and the worm 12 can limit the clamping block 7, enabling the clamping block 7 to position and clamp the reinforcing bars, and to position and clamp multiple sets of reinforcing bars of different specifications.
[0030] Furthermore, a connecting rod 13 is slidably connected to the bottom of the connecting frame 5. The connecting rod 13 extends into the interior of the connecting frame 5 and is fixedly connected to a limiting rod 14. A connecting ring 15 is fixedly connected to the outside of the connecting rod 13. A compression spring 16 is sleeved on the outside of the connecting ring 15 and the outside of the connecting rod 13. Multiple sets of fixing slots 17 are opened inside the first connecting frame 2 and the second connecting frame 3. Both the first connecting frame 2 and the second connecting frame 3 are connected to the limiting rod 14 through the fixing slots 17. The second connecting frame 3 is connected to the moving frame body 1 through a drive screw 18. Pulling the connecting rod 13 causes the limiting rod 14 to move, thereby fixing the slots 17. The internal displacement disconnects the limiting connection between the connecting frame 5 and the first connecting frame 2 or the second connecting frame 3, allowing the connecting frame 5 to move. The internal structure of the connecting frame 5 can be adjusted as needed. The connecting rod 13 is loosened, and the connecting ring 15 is moved by the compression spring 16, causing the connecting rod 13 to move the limiting rod 14. The limiting rod 14 is moved into the interior of the fixing groove 17 and is limited to the fixing groove 17, thus making the connecting frame 5 limited to the fixing groove 17. Rotating the drive screw 18 can move the second connecting frame 3, allowing the position of the multiple positioning components 4 on the top of the second connecting frame 3 to be adjusted for convenient use.
[0031] In this embodiment, the specific implementation scenario is as follows: In actual use, pulling the connecting rod 13 causes the limiting rod 14 to move, thereby displacing the inside of the fixing groove 17 and breaking the limiting connection between it and the first connecting frame 2 or the second connecting frame 3, allowing the connecting frame 5 to move. The inside of the connecting frame 5 is adjusted as needed. Releasing the connecting rod 13 causes the connecting ring 15 to move through the compression spring 16, causing the connecting rod 13 to move the limiting rod 14, moving the limiting rod 14 into the inside of the fixing groove 17 and establishing a limiting connection with it. This allows the connecting frame 5 to be connected to the fixing groove 17. Rotating the drive screw 18 can move the second connecting frame 3, allowing adjustment of the positions of the multiple positioning components 4 at the top of the second connecting frame 3 for convenient use, and placing the reinforcing bar. Between the two sets of clamping blocks 7, the rotating worm gear 12 drives the worm wheel 11 to rotate, causing the transmission rod 10 to rotate, which in turn drives the rotating block 6 to rotate. When the rotating block 6 rotates, it drives the guide groove 8 to rotate, causing the guide rod to move and the clamping block 7 to move. When the clamping block 7 comes into contact with the steel bar, the clamping groove 9 comes into contact with the steel bar. Through the "V" shaped structure design of the clamping groove 9, the steel bar can be clamped and positioned. When the clamping block 7 moves to the designated position, the self-locking property between the worm wheel 11 and the worm gear 12 can limit the clamping block 7, enabling the clamping block 7 to position and clamp the steel bar. It can also position and clamp multiple sets of steel bars of different specifications. Compared with the existing positioning structure, this utility model improves the overall practicality of the positioning structure through its design.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
