Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, specifically to a rebar positioning device. Background Technology

[0002] In the field of building construction, any reinforced concrete structure involves the process of binding and accepting steel mesh.

[0003] Currently, in various construction fields such as nuclear power plant construction, civil engineering, and bridge construction, the overall requirements of strict government supervision, high-quality national construction, and cost reduction and efficiency improvement in the construction industry are being met. Among these requirements, steel reinforcement construction is a crucial link in the construction process, and its process quality control and final acceptance are essential procedures that cannot be skipped.

[0004] A significant current problem is that after the rebar is tied but before final acceptance, the rebars inevitably shift to some extent, affecting quality and requiring rework. Furthermore, during rebar acceptance, a measuring tape is used to randomly check the rebar spacing according to specifications. However, with large quantities of rebar, this is inefficient, and random checks can lead to quality discrepancies. This conventional method results in overall quality inconsistencies and is slow, failing to meet the current national requirements for high-quality development.

[0005] In other words, existing technologies generally have the following drawbacks before final acceptance and release after the rebar tying is completed: 1. Quality deviation: During the construction process, the completed steel bars may shift, failing to meet the specifications. 2. Low efficiency: The self-inspection and acceptance processes are not very efficient; 3. Potential quality issues: For some pre-embedded steel bars, the displacement and deviation of the steel bars during the concrete pouring process may exceed the specifications.

[0006] Therefore, there is an urgent need to design a rebar positioning device to improve the quality of rebar tying, reduce rebar displacement, improve the quality and efficiency of on-site rebar construction, and thus increase the first-time acceptance rate. Utility Model Content

[0007] This utility model provides a rebar positioning device, which aims to reduce the displacement of rebar and improve the quality of on-site rebar construction.

[0008] This utility model is achieved through the following technical solution: a rebar positioning device, comprising multiple connecting bodies and multiple positioning rods, wherein adjacent connecting bodies are coaxially and detachably connected, and multiple positioning holes are spaced apart on the top of the connecting body along its axial direction, and the positioning rods are detachably connected to the positioning holes.

[0009] Compared with existing technologies, this solution has the following advantages and beneficial effects: In this design, the multiple connecting sections are detachable, allowing for flexible assembly of the corresponding number of connecting sections according to actual site conditions. Furthermore, the positioning holes at the top of the connecting sections facilitate the connection of positioning rods. The positioning rods are adjusted according to the diameter of the reinforcing bars or the spacing between adjacent reinforcing bars, allowing them to be inserted into the corresponding positioning holes. This allows the positioning rods to clamp a single reinforcing bar, or to position two adjacent positioning rods against two adjacent reinforcing bars, ensuring the reinforcing bars do not shift. It also helps to fix the spacing between adjacent reinforcing bars, preventing displacement of the tied reinforcing bars and thus improving the quality of on-site reinforcing bar construction.

[0010] In addition, the spacing between the positioning rods in this solution can quickly confirm whether the spacing between the reinforcing bars meets the specifications, thereby improving the efficiency of self-inspection and acceptance, and improving the quality of reinforcing bar construction and the first-time acceptance rate.

[0011] During assembly, this solution uses connectable connectors and adjustable positioning holes to quickly build a positioning frame that fits the steel mesh. In the positioning stage, the positioning rod provides rigid lateral restraint to the steel bars, preventing displacement during binding and pouring. It can directly confirm whether the spacing of the steel bars meets the specifications. The acceptance logic is simple and intuitive, greatly reducing errors in manual judgment and operation time. In the acceptance stage, there is no need to use a measuring tape for spot checks. It is only necessary to observe whether the steel bars are tightly fitted to the side wall of the positioning rod without gaps.

[0012] Finally, the rebar positioning device in this solution is highly practical because its various parts are detachable and reusable.

[0013] Furthermore, the spacing between two adjacent positioning holes is the same.

[0014] Beneficial effects: The design of identical spacing between adjacent positioning holes in this scheme eliminates the need for construction workers to perform complex spacing conversions or hole selection on-site. They only need to directly select the positioning hole group with the corresponding spacing specifications based on the rebar spacing requirements in the construction drawings. Since the hole spacing in the same group is completely consistent, the positioning baseline formed after inserting the positioning rod naturally conforms to the rebar arrangement requirements. Construction workers do not need to repeatedly measure the positioning rod spacing; they only need to place the rebars sequentially along the positioning rods to achieve uniform arrangement, greatly simplifying the operation steps.

[0015] At the same time, this design avoids the risk of misinsertion or omission due to irregular spacing of the positioning holes.

[0016] Furthermore, the positioning rod is threadedly connected to the positioning hole.

[0017] Beneficial effects: In this solution, the positioning rod and the positioning hole are connected by a thread to achieve a detachable connection. This connection method is simple and can provide a self-locking effect for the positioning rod. When the positioning rod is threadedly connected to the positioning hole, the position of the positioning rod is relatively stable, which can better position the reinforcing bar.

[0018] Furthermore, a screw is coaxially connected to the bottom of the positioning rod, and the diameter of the screw is smaller than the diameter of the positioning rod.

[0019] Beneficial effects: In this design, the diameter of the screw at the bottom of the positioning rod is smaller than the diameter of the positioning rod itself. This creates a stepped structure at the bottom of the positioning rod, with a large-diameter rod body and a small-diameter screw. The screw part can be fully screwed into the threaded section of the positioning hole, while the main body of the positioning rod, because its diameter is larger than the screw, is precisely locked at the top edge of the positioning hole, forming an axial limit. This structure provides clear feedback on the resistance after the positioning rod is screwed in (the bottom of the rod body contacts the stepped section of the smooth hole in the positioning hole). Construction personnel can quickly determine whether the connection is in place by feel, without the need for additional observation of the scale.

[0020] Furthermore, a positioning rod nut is connected to the top of the positioning rod, and the positioning rod nut has a regular polygonal structure.

[0021] Beneficial effects: This solution ensures that when the positioning rod is screwed into the positioning hole as required, it can be done with a regular wrench or an electric wrench. The positioning rod nut provides a force point for the use of auxiliary tools such as wrenches, making it convenient to tighten or loosen the positioning rod.

[0022] Furthermore, the connector has scale lines along its axial direction.

[0023] Beneficial effects: In this solution, the axial scale lines of the connecting body are marked with fixed units (such as 1mm, 5mm, 10mm), which can be directly used to verify the accuracy of the positioning hole spacing. Before construction, the operator does not need to use a tape measure to measure additionally, and can quickly confirm whether the spacing between adjacent positioning holes is consistent with the design requirements by using the scale lines.

[0024] Furthermore, one end of the connector is provided with a threaded hole, and the other end of the connector is coaxially connected with a connecting screw.

[0025] Beneficial effects: In this solution, adjacent connecting sections are detachably connected by connecting screws and threaded holes. This connection structure and method are simple and have higher operating efficiency.

[0026] In addition, in this solution, the connecting screw and the connecting body can be machined coaxially, and the threaded hole and the connecting screw are completely matched in specifications. Precise alignment can be achieved during splicing. The connecting screw of one section of the connecting body is screwed into the threaded hole of the other section of the connecting body. No additional adjustment is required to ensure that the axes of the two sections of the connecting body are coincident, effectively avoiding misalignment of the positioning hole caused by splicing deviation.

[0027] Furthermore, a locking unit is connected to the bottom of the connector, which is used to lock and fix the connector.

[0028] Beneficial effects: The locking unit in this solution can lock and fix the connecting body, ensuring the stability of the entire rebar positioning device and preventing the entire rebar positioning device from shifting. In practice, the locking unit can lock the connecting body to the rebar or other devices and limit the connection body, thereby enabling the entire rebar positioning device to effectively position the rebar.

[0029] Furthermore, the locking unit includes a locking ring and a locking rope, the locking ring being fixed to the bottom of the connecting body, and the locking rope passing through the locking ring.

[0030] Beneficial effects: In this solution, the locking unit's fixing ring is fixed to the connecting body, providing a fixed point for the entire locking rope. The locking rope is tied to the reinforcing bar or other structural device, thereby fixing and limiting the connecting body, ensuring the stability of the connecting body itself, and thus improving the stability of the entire reinforcing bar positioning device.

[0031] Furthermore, multiple locking units are provided, and the multiple locking units are distributed at intervals along the axial direction of the connecting body.

[0032] Beneficial effects: When multiple connectors are spliced ​​together to form a long-span positioning frame, a single or two-end locking unit is insufficient to support the frame's own weight and external construction forces, easily leading to problems such as mid-section sagging and lateral tilting. Multiple locking units are distributed axially at intervals to form a multi-point support system, which evenly transfers the self-weight and external forces of the connector to the reinforcing steel or other structures through each locking unit, significantly improving the connector's resistance to bending and overturning, as well as its stability.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0036] As one embodiment of this utility model, such as Figures 1-2 As shown, this embodiment provides a rebar positioning device, including multiple connecting bodies and multiple positioning rods 7. Adjacent connecting bodies are coaxially and detachably connected. Multiple positioning holes 3 are spaced apart on the top of the connecting body along its axial direction. The positioning rods 7 are detachably connected to the positioning holes 3. In this embodiment, the positioning rods 7 are arranged perpendicularly to the connecting body to facilitate the positioning of the rebar.

[0037] In one embodiment, such as Figure 1 As shown, in this embodiment, the connector is a cylindrical structure made of high-hardness stainless steel, and one end of the connector has a threaded hole 6. The other end of the connector is coaxially connected to a connecting screw 5. In this embodiment, the connecting screw 5 is integrally formed with the connector. Figure 1 As shown, the two adjacent connecting bodies are the first connecting body 1 and the second connecting body 2. When the first connecting body 1 and the second connecting body 2 are connected to each other, the connecting screw 5 at the end of the second connecting body 2 is aligned with the threaded hole 6 at the end of the first connecting body 1 and tightened to fix it, thereby realizing the connection between the two adjacent connecting bodies (the first connecting body 1 and the second connecting body 2).

[0038] In this embodiment, the number of connectors can be selected according to the actual needs on site, and the connectors can be connected and assembled according to the above connection method.

[0039] In one embodiment, such as Figure 1 As shown, the spacing between two adjacent positioning holes 3 is the same. In this embodiment, the diameter of the positioning hole 3 is 3mm, and the spacing between adjacent positioning holes 3 is 5mm. Multiple positioning holes 3 are evenly arranged along the axial direction of the connecting body.

[0040] In one embodiment, such as Figure 1 As shown, in this embodiment, a scale line 4 is provided on the connecting body along its axial direction. In this embodiment, the scale value of the scale line 4 is the same as the distance between two adjacent positioning holes 3, that is, the scale line 4 is marked on the connecting body at a distance of 5mm.

[0041] In one embodiment, such as Figure 1 As shown, in this embodiment, the positioning rod 7 is threadedly connected to the positioning hole 3. Depending on the different needs on site, the positioning rod 7 is screwed into the corresponding positioning hole 3 as required. This connection method is simple and easy to operate.

[0042] In one embodiment, such as Figure 1 As shown, in this embodiment, a screw is coaxially connected to the bottom of the positioning rod 7. The screw and the positioning rod 7 can be welded together or integrally formed. In this embodiment, the screw and the positioning rod 7 are integrally formed. The diameter of the screw is smaller than the diameter of the positioning rod 7, thereby forming a stepped structure at the bottom of the positioning rod 7. In this way, during the process of tightening the positioning rod 7 in the positioning hole 3, the stepped structure can provide a clear signal and feel for the positioning rod 7 to be tightened in place.

[0043] In one embodiment, such as Figure 1 As shown, in this embodiment, the top of the positioning rod 7 is connected to the positioning rod nut 8, which has a regular polygonal structure. In this embodiment, the positioning rod 7 nut and the positioning rod nut 8 are welded and fixed or integrally formed, and the positioning rod nut 8 in this embodiment has a regular hexagonal structure.

[0044] In this embodiment, when screwing the positioning rod nut 8 into or out of the positioning hole 3 as required, an auxiliary tool, such as an electric wrench or a manual wrench, can be used to cooperate with the positioning rod nut 8 and to turn the positioning rod 7 so that the positioning rod 7 is fixed at the positioning rod 7 or removed from the positioning rod 7.

[0045] The positioning rod nut 8 provides a force application point for the auxiliary tool, making it easy to tighten or loosen the positioning rod 7.

[0046] In one embodiment, such as Figure 1 As shown, a locking unit is connected to the bottom of the connector. The locking unit is used to lock and fix the connector. Specifically, in this embodiment, the locking unit includes a locking ring 10 and a locking rope 9. The locking ring 10 is fixed to the bottom of the connector. In this embodiment, the locking ring 10 is U-shaped, and both ends of the locking ring 10 are welded and fixed to the bottom of the connector. The locking rope 9 passes through the locking ring 10.

[0047] In this embodiment, the locking rope 9 is tied to the reinforcing bar or other structural device to fix and limit the connection body, ensuring the stability of the connection body itself, thereby improving the stability of the entire reinforcing bar positioning device and avoiding the instability caused by displacement of the connection body itself, which would result in the inability to stably limit the reinforcing bar.

[0048] In one embodiment, the locking rope 9 is made of iron wire, which has good toughness and is easy to tie and fix. When in use, the two ends of the locking rope 9 are tied to the nearby steel bars to fix the connector and make the connector more stable, so as to limit the position of the steel bars and ensure that the steel bars do not deviate.

[0049] In one embodiment, combined Figure 2 As shown, in this embodiment, there are multiple locking units, which are distributed at intervals along the axial direction of the connecting body. Specifically, in this embodiment, the multiple locking units are spaced 1m apart.

[0050] The specific implementation process is as follows: First, select the corresponding number of high-hardness stainless steel cylindrical connectors based on the required length of the steel mesh at the construction site. Taking the splicing of 6 connectors to form a steel bar positioning device as an example, select 6 long connectors (including connector 1, connector 2, ..., connector 6). During splicing, align the integrally formed connecting screw 5 at the end of the next connector (e.g., connector 2) with the threaded hole 6 at the end of the previous connector (e.g., connector 1), and tighten clockwise until the connecting screw 5 is fully screwed into the threaded hole 6, ensuring that the two connectors are coaxial and without looseness. Repeat this operation to splice 6 connectors in sequence to form an integral rod-like structure.

[0051] Referring to the rebar spacing requirements in the construction drawings, install positioning rods 7 at the axially evenly distributed positioning holes 3 on the top of the connector. Since positioning rods 7 and positioning holes 3 are connected by threads, and the bottom of positioning rods 7 has a smaller diameter screw integrally formed coaxially, during installation, first align the screw at the bottom of positioning rod 7 with the positioning hole 3, then use an electric wrench (or manual wrench) to engage the hexagonal positioning nut 8 at the top of positioning rod 7, and tighten positioning rod 7 clockwise. When significant resistance is felt (the stepped positioning rod 7 body contacts the top of the connector), stop tightening. At this point, positioning rod 7 is vertically fixed to the connector, completing the installation of a single positioning rod 7. Install positioning rods 7 in this manner at all required positioning locations to form a uniformly distributed rebar limiting structure.

[0052] In this embodiment, one locking unit is set every 1m along the axial direction of the connector. Each locking unit consists of a fastening positioning ring 10 welded to the bottom of the connector and a locking rope 9 passing through the positioning ring. After the connector is assembled, the connector is transported as a whole to the rebar binding area, and the position of the connector is adjusted so that the connector is perpendicular to the rebar, while the distribution direction of the positioning rods 7 is consistent with the designed arrangement direction of the rebar.

[0053] Multiple tied reinforcing bars are sequentially attached to multiple positioning rods 7, with the spacing between two adjacent reinforcing bars being the same as the spacing between two adjacent positioning rods 7. This allows the positioning rods 7 to effectively position the reinforcing bars and quickly determine whether the spacing between adjacent reinforcing bars meets the specifications. In this embodiment, a single reinforcing bar can also be secured between two adjacent positioning rods 7. By adjusting the spacing between the positioning rods 7, the diameter of the reinforcing bar can be accommodated. This method is particularly suitable for limiting and fixing large-diameter reinforcing bars.

[0054] For each locking unit, the two ends of the locking rope 9 (iron wire) passing through the tightening positioning ring 10 are wrapped upwards and tied to the fixed steel bars or formwork support structure near the work area. When tying, ensure that the iron wire is taut and not loose. Through the coordinated fixing of multiple sets of locking units, a rigid connection is formed between the connector and the work surface, preventing the connector from shifting during subsequent construction, thereby ensuring the stable positioning of the steel bars.

[0055] Since the positioning rods 7 are perpendicular to the connecting body and evenly spaced, the spacing between the positioning rods 7 can be adjusted according to the spacing between the reinforcing bars. Then, the sidewalls of the reinforcing bars can be tightly fitted with the positioning rods 7 to ensure that the spacing between adjacent reinforcing bars is strictly controlled within a fixed spacing. At the same time, the positioning rods play a positioning role, which can effectively prevent the reinforcing bars from shifting, thereby improving the quality of on-site reinforcing bar construction.

[0056] During the acceptance phase, the acceptance personnel do not need to use a measuring tape for spot checks. They can confirm the quality through two visual inspections: first, observe whether the reinforcing bars are tightly fitted with the positioning rod 7 without any obvious gaps; second, check the corresponding positions of the scale line 4 on the connector and the end of the reinforcing bar to confirm whether the spacing of the reinforcing bars meets the requirements of the drawings.

[0057] After the reinforcing steel has passed inspection and the concrete has initially set, the device is disassembled as follows: First, cut all the wires of the locking units to release the connection between the connector and the working surface; second, use an electric wrench to turn the positioning rod nuts 8 counterclockwise and remove all the positioning rods 7; third, unscrew the threaded connections between the connectors section by section to disassemble each connector. Finally, clean the concrete residue from the connectors and the surfaces of the positioning rods 7, and store them separately for use in subsequent construction of similar reinforcing steel. The reinforcing steel positioning device in this utility model is reusable, saving costs.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application.
