Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a tool for sampling steel bar joints. Background Technology

[0002] In construction engineering, sampling and inspecting material welding points is a crucial step in ensuring project quality. However, traditional material sampling methods have many drawbacks and urgently need improvement. Firstly, sample accuracy is difficult to guarantee. Traditional sampling separates measurement and cutting processes; measurement and marking are completed first, followed by cutting and sampling. This is prone to deviations between the actual cutting position and the measurement position due to factors such as displacement of measuring tools and vibrations during cutting. This results in substandard sample dimensional accuracy, affecting the accuracy of subsequent tests and even rendering the sample unusable, increasing costs and time. Secondly, irregular cut surfaces are common. When manually operating a cutting machine, varying operator skill levels and instability can easily lead to irregular cut surfaces, resulting in serrated or inclined surfaces. This damages the original structure of the material, not only interfering with the assessment of the material's true performance and affecting the reliability of test results, but also posing significant safety hazards. Summary of the Invention

[0003] Purpose of the utility model: This utility model provides a rebar joint sampling tool that integrates an adjustable clamp and a positioning ruler.

[0004] Technical solution: This utility model provides a rebar joint sampling tool, including an adjustable positioning scale and an adjustable clamp for clamping and fixing the rebar; the adjustable clamp is connected to the adjustable positioning scale by a connecting block; the adjustable clamp includes a clamping cylinder and a clamping bolt, a threaded hole is opened on one side of the clamping cylinder, the clamping bolt is engaged with the threaded hole, and the rear end of the clamping bolt can extend into the inner cavity of the clamping cylinder after being screwed in, and the clamping bolt is tightened after the rebar passes through the clamping cylinder, thereby realizing the clamping and fixing of the rebar.

[0005] Furthermore, the adjustable positioning scale includes a scale body, a slider, an adjusting bolt, a nut, and a pointer; the scale has a central groove along its length; the slider is a hollow cylinder structure, fitted onto the scale body, with the inner diameter of the slider matching the outer diameter of the scale for sliding connection; one side of the slider is fixedly connected to the pointer, which extends to the outside of the scale to point to the adjustable clamp side; the adjusting bolt passes through the top of the slider, with its threaded section embedded in the central groove of the scale body, and the nut engaging with the threaded end of the adjusting bolt; rotating the adjusting bolt pushes the slider to move longitudinally along the scale for precise positioning; when the adjusting bolt is tightened, the nut is secured to the scale body through the engagement of the nut and the threaded end of the adjusting bolt, thereby fixing the slider at the current position of the scale.

[0006] Furthermore, the bolt end is equipped with a replaceable rubber pad, which can effectively protect the surface of the reinforcing bar and prevent damage to the reinforcing bar.

[0007] Furthermore, the sleeve is provided with anti-slip texture to increase the friction between the sleeve and the reinforcing bar, preventing the reinforcing bar from sliding during clamping.

[0008] Furthermore, the connecting block includes a clamp connecting block and a scale connecting block. One side of the clamp connecting block is fixedly connected to the clamping cylinder, and the other side is provided with a slot. One side of the scale connecting block is connected to the scale body, and the other side is provided with a protruding buckle that matches the slot. The slot and the buckle form a detachable structure, so that different types of sleeves can be produced according to different types of column steel bars.

[0009] Furthermore, the slider is made of steel plate.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model uses an adjustable clamp to firmly hold and fix the reinforcing bar, and utilizes a ruler that closely matches the clamp for precise measurement, avoiding the errors caused by the separation of measurement and cutting in traditional methods. It prevents dimensional deviations caused by displacement of measuring tools and cutting vibration, ensuring sample dimensional accuracy, reducing test errors and cost waste. At the same time, the clamp fixing the reinforcing bar reduces displacement and shaking during cutting, providing a stable foundation for the angle grinder, making the cut surface regular, ensuring the integrity of the reinforcing bar structure, and improving test accuracy. Using a clamp to fix the reinforcing bar reduces the risk of manual fixing, reduces reliance on operator experience, and makes the operation more standardized. The integrated design of the clamp and ruler allows for close connection between measurement and cutting processes, making operation convenient and quick, improving sampling efficiency, and facilitating portability and storage, adapting to the changing construction site environment.

Detailed Implementation

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 4 As shown, a rebar joint sampling device includes an adjustable positioning scale 1 and an adjustable clamp 2 for fixing and holding the rebar. The adjustable clamp 2 is connected to the adjustable positioning scale 1 via a connecting block 3. The adjustable clamp 2 includes a clamping cylinder 201 with an inner diameter of 25 mm and a wall thickness of 10 mm, and a clamping bolt 202. The clamping bolt 202 is a hexagonal head bolt with a head diameter of 50 mm and a screw diameter of 15 mm. A threaded hole is provided on one side of the clamping cylinder 201, and the clamping bolt 202 mates with the threaded hole. After the clamping bolt 202 is screwed in, its end can extend into the inner cavity of the clamping cylinder 201. After the rebar 4 passes through the clamping cylinder 201, the clamping bolt 202 is tightened, thereby achieving the clamping and fixing of the rebar 4.

[0018] like Figure 1 , Figure 3 , Figure 4 As shown, the adjustable positioning scale 1 includes a scale body 101, a slider 102, an adjusting bolt 103, a nut 104, and a pointer 105. The scale body 101 has a central groove 5 along its length. The slider 102 is a hollow cylinder structure, made of steel plate with a wall thickness of 1mm, 51mm in length, and 40mm in width, and is fitted onto the scale body 101 for sliding connection. One side of the slider 102 is fixedly connected to the pointer 105, which extends to the outside of the scale body 101 to point to the adjustable clamp side for measuring the length of the reinforcing bar 4. The adjusting bolt... 103 penetrates the top of slider 102, and the threaded section of the screw is embedded in the central groove 5. Nut 104 engages with the threaded end of adjusting bolt 103. Adjusting bolt 103 is a hexagonal head bolt with a head diameter of 18mm and a thickness of 10cm. The screw diameter is 18mm. Rotating adjusting bolt 103 pushes slider 102 to move longitudinally along scale body 101 to achieve precise positioning. When adjusting bolt 103 is tightened, the engagement of nut 104 with the threaded end of adjusting bolt 103 secures nut 104 to scale body 101, thereby fixing slider 102 in the current position of scale body 101.

[0019] like Figure 1 As shown, the connecting block 3 includes a clamp connecting block 301 and a positioning scale connecting block 302. One side of the clamp connecting block 301 is fixedly connected to the clamping cylinder 201, and the other side is provided with a slot. One side of the positioning scale connecting block 302 is connected to the scale body 101, and the other side is provided with a protruding buckle that matches the slot. The slot and the buckle form a detachable structure.

[0020] like Figures 1 to 4As shown, during operation, the rebar joint sampling device is placed flat on the workbench to ensure stability. The rebar 4 to be clamped is passed through the clamping cylinder 201, with the end of the rebar 4 extending an appropriate length beyond the clamping cylinder 201. The clamping bolt 202 is taken and aligned with the threaded hole on the side of the clamping cylinder, then screwed in. As the clamping bolt 202 is screwed in, its end gradually extends into the inner cavity of the clamping cylinder 201, pressing against the rebar 4. The clamping bolt 202 is continued to tighten, applying pressure to the rebar 4 until it is firmly clamped within the clamping cylinder 201. The clamping cylinder 201 has anti-slip grooves inside, preventing the rebar 4 from sliding within it. The end of the clamping bolt 202 has a replaceable rubber pad to prevent damage to the rebar. By rotating the adjusting bolt 103, the slider 102 is pushed longitudinally along the scale body 101, causing the pointer 105 to point to the predetermined sampling position, achieving precise positioning. Tighten the adjusting bolt 103, and use the engagement of the nut 104 with the threaded end of the adjusting bolt 103 to secure the nut 104 to the scale body 101, thus fixing the slider 102 at the current sampling position. With the reinforcing bar 4 fixed in the clamping cylinder 201, use an angle grinder to sample the reinforcing bar joint. After sampling, unscrew the adjusting bolt 103 counterclockwise to separate the end of the adjusting bolt 103 from the reinforcing bar 4. Remove the reinforcing bar 4 from the clamping cylinder 201.
