Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rebar positioning devices, specifically to a combined rebar spacing positioning clamp. Background Technology
[0002] In construction engineering, rebar tying is a core step in the construction of reinforced concrete structures. The precise control of the rebar spacing has a decisive impact on the structural safety and durability. First, the rebar spacing directly affects the cooperative stress performance of concrete and rebar. Moreover, the positional error of the rebar will change the thickness of the protective layer, which directly affects the fire resistance and durability of the structure.
[0003] Traditional methods for positioning rebars often employ fixed-size clamps or manual marking. In these two methods, manual marking is susceptible to the operator's skill level, and conventional clamps, often designed to a single size, are ill-suited to varying design parameters and different rebar spacing requirements. Frequent clamp replacements or manual adjustments are necessary, leading to inefficiency and accumulated errors. Furthermore, the lack of effective restraints during rebar tying makes the rebars vulnerable to external disturbances, requiring repeated adjustments and extending the construction period. Therefore, a suitable device is needed to address these issues. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a combined rebar spacing positioning clamp, which solves the problems of cumbersome positioning and low efficiency in the existing rebar tying process.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a combined rebar spacing positioning clamp, including a support and a replacement plate, wherein the support is detachably connected to the replacement plate through a first splicing mechanism, and the bottom of the support is fixedly connected with anti-slip teeth;
[0006] The upper surface of the replacement plate is provided with several parallel and spaced positioning grooves. The positioning grooves are through grooves in the second direction of the replacement plate. The inside of the positioning grooves is provided with rubber pads to increase friction. The inside of the positioning grooves is also provided with limiting mechanisms to fix the reinforcing bars. The two sides of the replacement plate are respectively provided with connecting blocks and connecting grooves. The connecting blocks and connecting grooves are detachably connected to splice adjacent replacement plates.
[0007] Optionally, the first splicing mechanism includes a wedge groove and a wedge block. The wedge block is fixedly connected to the lower surface of the replacement plate, and the wedge groove is formed on the upper surface of the support. The wedge groove and the wedge block are detachably connected to limit the replacement plate in a first direction.
[0008] Optionally, the anti-slip teeth can be inserted into the inner wall of the wedge-shaped groove for stacking supports.
[0009] Optionally, the upper surface of the support is further provided with a second splicing mechanism, which is used to limit the replacement plate in a second direction.
[0010] Optionally, the second splicing mechanism includes a notch and a positioning plate. The positioning plate is fixedly connected to the upper surface of the support and is arranged along the first direction. The notch is opened on the lower surface of the replacement plate and corresponds to the position of the positioning plate.
[0011] Optionally, the limiting mechanism includes a compression spring and a top block. The top block is disposed on the inner wall of the positioning groove to fix the reinforcing bar. The compression spring is fixedly connected to the back of the top block and its other end abuts against the inner wall of the positioning groove to push the top block outward.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.
[0020] Please see Figures 1 to 3 The present invention provides a technical solution: a combined rebar spacing positioning clamp, including a support 1 and a replacement plate 2. The support 1 is detachably connected to the replacement plate 2 through a first splicing mechanism. Anti-slip teeth 3 are fixedly connected to the bottom of the support 1.
[0021] The upper surface of the replacement plate 2 is provided with several parallel and spaced positioning grooves 4. The positioning grooves 4 are through grooves in the second direction of the replacement plate 2. The inside of the positioning grooves 4 is provided with rubber pads 5 to increase friction. The inside of the positioning grooves 4 is also provided with a limiting mechanism to fix the reinforcing bars. The two sides of the replacement plate 2 are respectively provided with connecting blocks 6 and connecting grooves 7. The connecting blocks 6 and connecting grooves 7 are detachably connected to splice adjacent replacement plates 2.
[0022] Support 1 is placed on a concrete pad. The anti-slip teeth 3 at the bottom can be embedded in the concrete surface to prevent support 1 from moving. Replacement plate 2 is installed on support 1. The positioning groove 4 is arc-shaped. There are various templates for the arc size of positioning groove 4 and the spacing between positioning groove 4. The corresponding arc and spacing can be selected according to actual needs. The limiting mechanism in positioning groove 4 initially fixes the reinforcing bar to prevent the reinforcing bar from shaking during the binding process. The two sides of replacement plate 2 can be spliced together by connecting block 6 and connecting groove 7, thereby extending the length of replacement plate 2.
[0023] In this embodiment, as a preferred option, the first splicing mechanism includes a wedge groove 8 and a wedge block 9. The wedge block 9 is fixedly connected to the lower surface of the replacement plate 2, and the wedge groove 8 is opened on the upper surface of the support 1. The wedge groove 8 and the wedge block 9 are detachably connected to limit the replacement plate 2 in the first direction.
[0024] The wedge block 9 can be inserted into the wedge groove 8 from top to bottom. After being inserted into the wedge groove 8, the first splicing mechanism can limit the support 1 and the replacement plate 2 in the first direction to prevent them from moving relative to each other. At the same time, it can play a positioning role during installation and reduce deviations during the installation process.
[0025] In this embodiment, as a preferred option, the anti-slip teeth 3 can be inserted into the inner wall of the wedge-shaped groove 8 to stack the support 1.
[0026] During transportation, multiple supports 1 can be spliced together vertically. The anti-slip teeth 3 of the upper support 1 can be inserted into the wedge-shaped groove 8 of the lower support 1. At the same time, the lower part of the support 1 is also provided with a groove that matches the positioning. During transportation, the supports 1 can be interlocked to improve the stability during transportation.
[0027] In this embodiment, as a preferred option, the upper surface of the support 1 is further provided with a second splicing mechanism. The second splicing mechanism is used to limit the replacement plate 2 in the second direction. The second splicing mechanism includes a notch 10 and a positioning plate 11. The positioning plate 11 is fixedly connected to the upper surface of the support 1 and is arranged along the first direction. The notch 10 is opened on the lower surface of the replacement plate 2 and corresponds to the position of the positioning plate 11.
[0028] After the first splicing mechanism limits the support 1 and the replacement plate 2 in the first direction, when the support 1 and the replacement plate 2 are installed together, the notch 10 will engage with the positioning plate 11, thereby limiting the support 1 and the replacement plate 2 in the second direction. In conjunction with the first splicing mechanism, the purpose of limiting the replacement plate 2 in two directions is achieved, further reducing the shaking of the support 1 during construction.
[0029] In this embodiment, as a preferred option, the limiting mechanism includes a compression spring 12 and a top block 13. The top block 13 is disposed on the inner wall of the positioning groove 4 to fix the reinforcing bar. The compression spring 12 is fixedly connected to the back of the top block 13 and the other end abuts against the inner wall of the positioning groove 4 to push the top block 13 outward.
[0030] The top block 13 is inclined at an angle. When the reinforcing bar is placed into the arc groove, the reinforcing bar will push the top blocks 13 on both sides into the replacement plate 2. After the reinforcing bar falls into the arc groove, the compression spring 12 will push the top block 13 to reset, thereby limiting the reinforcing bar above and preventing the reinforcing bar from shaking. The rubber pad 5 at the bottom can also increase the friction between the reinforcing bar and the arc groove, further reducing the shaking of the reinforcing bar during the binding process.
[0031] In this embodiment, as a preferred option, a guide groove 14 is provided on one side of the connecting block 6, and a guide post 15 is fixedly connected to the inner wall of the connecting groove 7. The guide post 15 is inserted into the guide groove 14 to position the height of the adjacent replacement plate 2.
[0032] When connecting block 6 and connecting groove 7 are spliced, guide post 15 in connecting groove 7 can be inserted into guide groove 14 on connecting block 6 from top to bottom. The bottom of guide groove 14 is closed. After the guide post 15 is inserted into guide groove 14 and inserted to the bottom, it can ensure that the replacement plates 2 on both sides are at the same horizontal height, so as to prevent the installation plates on both sides from being different in height during the installation process and improve the accuracy of the laying process.
[0033] In this invention, the working steps of the device are as follows:
[0034] 1. Select a replacement plate 2 unit of the corresponding size according to the needs of on-site construction, and then fix the support 1 and the replacement plate 2 together through the first splicing mechanism and the second splicing mechanism;
[0035] 2. According to the required construction length, the adjacent replacement plates 2 are spliced together by connecting blocks 6 and connecting grooves 7;
[0036] 3. Lay the support 1 and replacement plate 2 on the concrete pad, ensuring that the anti-slip teeth 3 are firmly installed between the pad and the pad. After installation, place the reinforcing bars in the slots, and then pour the concrete.
[0037] 4. After the pouring is completed, support 1 and replacement plate 2 do not need to be removed and are embedded in the concrete.
[0038] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
