Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a portable tool for controlling the spacing of reinforcing bars. Background Technology

[0002] In the field of steel reinforcement installation in building construction, the precise control of steel bar spacing directly affects the load-bearing capacity, seismic performance, and overall construction quality of concrete structures. Currently, the mainstream methods for controlling steel bar spacing in the industry mainly rely on two types of operations: First, during the steel bar binding process, construction workers judge and adjust the steel bar spacing based on their personal experience. This method is greatly affected by subjective human factors and is prone to spacing deviations due to differences in experience and operator fatigue. Furthermore, it lacks a unified quantitative standard, making it difficult to ensure construction consistency. Second, during the steel reinforcement project acceptance stage, a measuring tape is used for re-inspection. This process requires at least two workers to fix the measuring tape scale at both ends of the steel bars and then measure and verify the spacing between each pair of steel bars one by one.

[0003] However, the above-mentioned traditional methods have significant drawbacks: on the one hand, tape measure re-inspection requires multiple people to work together, resulting in high labor costs; on the other hand, the point-by-point measurement mode is inefficient, especially in the inspection of large-area steel mesh (such as floor slab and wall panel steel reinforcement), which consumes a lot of time and seriously slows down the construction progress. In addition, tape measure measurement is easily affected by environmental factors (such as narrow site space causing the tape measure to be unable to be straightened), which further reduces the measurement accuracy and may result in the failure to detect unqualified steel reinforcement spacing in time, leaving structural safety hazards.

[0004] Therefore, it is necessary to provide a new portable rebar spacing control tool to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a portable rebar spacing control tool.

[0006] The portable rebar spacing control tool provided by this utility model includes a plastic frame, in which an installation groove is provided, and a detachable connecting rod is installed in the installation groove; The central connecting rod is fitted with multiple sliding seats that are slidably connected, and the upper surface of the sliding seats is fitted with threaded spacer teeth. Two symmetrically distributed U-shaped sliding side plates are fixed on the sliding seats, and the U-shaped sliding side plates are slidably connected to the upper surface of the plastic frame side plates. The upper surface of the U-shaped sliding side plates is provided with threaded fixing holes, and threaded positioning screws are inserted into the threaded fixing holes. A pointer is fixedly installed on the U-shaped sliding side plate located on the outside of the plastic frame; The plastic frame has scale lines on both the front and back panels.

[0007] Preferably, both sides of the plastic frame are provided with threaded mating holes that communicate with the mounting groove, and the two threaded mating holes are coaxially arranged.

[0008] Preferably, both ends of the connecting rod are provided with threaded mounting holes, and the threaded mounting holes are of the same specifications as the threaded mating holes. A threaded connecting rod is inserted into the threaded mating holes, and the mounting rod extends into the threaded mounting holes and is threadedly fixedly connected to the threaded mounting holes.

[0009] Preferably, the sliding seat is fitted onto the central connecting rod through the through cavity, and the sliding seat also has two limiting grooves that communicate with the through cavity and are symmetrically distributed.

[0016] 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 accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1 to 5 This utility model provides a portable rebar spacing control tool, which includes a plastic frame 1, a central connecting rod 2, and spacer teeth 4.

[0019] In the embodiments of this utility model, please refer to Figures 1 to 5 The plastic frame 1 has fixed arms 11 on both sides. The plastic frame 1 has an installation groove 1a, and a detachable connecting rod 2 is installed in the installation groove 1a. Multiple sliding seats 3 are fitted on the connecting rod 2. Specifically, the sliding seats 3 are fitted on the connecting rod 2 through the through cavity 3a. Two symmetrically distributed U-shaped sliding side plates 31 are fixed on the sliding seats 3. The upper surface of the sliding seats 3 is fitted with threaded spacer teeth 4. The top of the sliding seats 3 is provided with a threaded groove 3c, and the connecting end of the spacer teeth 4 is provided with a threaded part that matches the threaded groove 3c.

[0020] Both sides of the plastic frame 1 are provided with threaded mating holes 1b that communicate with the mounting groove 1a, and the two threaded mating holes 1b are coaxially arranged. Both ends of the central connecting rod 2 are provided with threaded mounting holes 2a, and the threaded mounting holes 2a are the same as the threaded mating holes 1b. A threaded connecting mounting screw 6 is inserted into the threaded mating hole 1b, and the mounting screw 6 extends into the threaded mounting hole 2a and is threadedly fixedly connected to the threaded mounting hole 2a.

[0021] It should be noted that: when assembling this application, the number of sliding seats 3 used is selected according to the actual situation of the construction site. All sliding seats 3 are fitted onto the central connecting rod 2, and then the central connecting rod 2 is placed into the mounting groove 1a opened in the plastic frame 1. At this time, each sliding seat 3 is adjusted so that the U-shaped sliding side plates 31 on both sides are mounted on the upper surface of the side plate of the plastic frame 1 (to keep the sliding smooth). Therefore, the threaded mounting holes 2a on both sides of the central connecting rod 2 are coaxially set with the threaded mating holes 1b on both sides of the plastic frame 1. Then, the mounting screw 6 is passed through the threaded mating hole 1b and screwed into the threaded mounting hole 2a, thus completing the installation of the central connecting rod 2 and the sliding seats 3 in the plastic frame 1. After completion, multiple spacer teeth 4 are sequentially threaded into the threaded grooves 3c opened in each sliding seat 3. When it is necessary to add or remove the spacer teeth 4, unscrew the mounting screw 6, remove the central connecting rod 2 from the plastic frame 1, then add or remove the sliding seat 3 on the central connecting rod 2, and then thread the spacer teeth 4 onto the sliding seat 3.

[0022] In this embodiment: if the spacer teeth 4 are reduced, the spacer teeth 4 can be directly unscrewed from the threaded groove 3c of the sliding seat 3.

[0023] Furthermore, the sliding seat 3 has two symmetrically distributed limiting grooves 3b that communicate with the through cavity 3a, and the outer rod surface of the connecting rod 2 is fixedly fitted with two symmetrically distributed limiting protrusions 21 that are adapted to the limiting grooves 3b. Thus, when the sliding seat 3 is fitted onto the connecting rod 2, the limiting grooves 3b and the limiting protrusions 21 work together to prevent the sliding seat 3 from rotating around the connecting rod 2.

[0024] The plastic frame 1 has a mounting plate 13 fixedly installed at its bottom, which facilitates the installation of the plastic frame 1.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 5 The U-shaped sliding side plate 31 is slidably connected to the upper surface of the side plate of the plastic frame 1. The upper surface of the U-shaped sliding side plate 31 is provided with a threaded fixing hole 31a, and a threaded positioning screw 5 is inserted into the threaded fixing hole 31a. A pointer 32 is fixedly installed on the U-shaped sliding side plate 31 located on the outside of the plastic frame 1. Scale lines 12 are provided on both the front and rear plates of the plastic frame 1.

[0026] It should be noted that: according to the value indicated by the pointer 32 on the scale line 12, the spacing between each interval tooth 4 is adjusted, and then the positioning screw 5 is tightened so that the U-shaped sliding side plate 31 is fixed on the side plate of the plastic frame 1, thereby completing the fixed distribution of each interval tooth 4.

[0027] After the reinforcing bars are tied, this application is used to check them. Specifically, the spacing of each spacer tooth 4 is adjusted, and then it is inserted into the gaps in the distribution of the reinforcing bars, so that the outermost spacer tooth 4 is in contact with the outermost reinforcing bar as a reference (e.g., Figure 6 As shown, since each spacer tooth 4 corresponds to the scale line 12, the spacing between the reinforcing bars can be accurately and quickly determined. Moreover, this application can be operated by one person, and the spacing between the reinforcing bars can be directly and precisely controlled. Unsuitable reinforcing bars can be directly adjusted, saving labor and improving work efficiency. Furthermore, since the plastic frame 1, the central connecting rod 2, the sliding seat 3, and the spacer teeth 4 are all detachable, they can be quickly replaced when a component is damaged.

[0028] In addition, the pointer 32 on the sliding seat 3 can accurately point to the value of the scale line 12, so that the spacing adjustment of the interval teeth 4 and the verification of the rebar spacing have clear quantitative basis, avoiding the subjective bias of traditional experience judgment. At the same time, the interval teeth 4 directly fit with the gap of the rebar, which can quickly identify the abnormal spacing position. Compared with measuring with a tape measure point by point, the accuracy error can be controlled smaller, and no secondary conversion is required, and the result is more intuitive.

[0029] In this embodiment: the plastic frame 1 and the sliding seat 3 can both be made of high-strength plastic material, while the spacer teeth 4 can be made of hollow aluminum alloy material, thereby reducing the weight of the entire device.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
