Description

Technical Field

[0001] This application relates to the field of construction testing technology, and in particular to a device for inspecting rebar spacing. Background Technology

[0002] In the construction industry, steel bars are the primary load-bearing material, and the accuracy of their spacing directly affects the safety and stability of the structure. Currently, the inspection of steel bar spacing on construction sites generally relies on visual inspection. However, in terms of accuracy, manual measurement is easily affected by factors such as the operator's skill, experience, and the site environment, leading to errors in the measurement results.

[0003] Some techniques employ simple measuring tools to control rebar spacing, such as tape measures and rangefinders. However, these tools are mostly of fixed dimensions and cannot accommodate rebar spacing requirements of different specifications. Measurements require significant time and manpower, especially in large-area or complex structures where efficiency is paramount. Other techniques utilize high-precision measuring equipment, which is not only complex to use and requires specialized training, but also expensive and has high maintenance costs. Therefore, there is an urgent need for a simple and efficient rebar spacing inspection device. Utility Model Content

[0021] In the construction industry, steel bars are the primary load-bearing material, and the accuracy of their spacing directly affects the safety and stability of the structure. Currently, the inspection of steel bar spacing on construction sites generally relies on visual inspection. However, in terms of accuracy, manual measurement is easily affected by factors such as the operator's skill, experience, and the site environment, leading to errors in the measurement results.

[0022] Some techniques employ simple measuring tools to control rebar spacing, such as tape measures and rangefinders. However, these tools are mostly of fixed dimensions and cannot accommodate rebar spacing requirements of different specifications. Measurements require significant time and manpower, especially in large-area or complex structures where efficiency is paramount. Other techniques utilize high-precision measuring equipment, which is not only complex to use and requires specialized training, but also expensive and has high maintenance costs. Therefore, there is an urgent need for a simple and efficient rebar spacing inspection device.

[0023] The following describes specific embodiments in conjunction with... Figures 1 to 4 The technical solution of this application will be described in further detail.

[0024] Some embodiments of this application provide a rebar spacing inspection device, such as... Figure 1 As shown, it includes: a strip-shaped main body 1; a sliding groove 1-1 located on the strip-shaped main body 1 and arranged along the length direction of the strip-shaped main body 1; a plurality of sliders 2 slidably mounted on the sliding groove 1-1; a plurality of slots 1-2 equidistantly arranged on one side of the sliding groove 1-1 along the length direction, the slots 1-2 being used to cooperate with the sliders 2; a clamping structure 3 disposed at one end of the sliders 2, the clamping structure 3 being used to cooperate with a reinforcing bar; and a locking structure 4 disposed on the sliders 2, the locking structure 4 being used to lock the sliders 2 within the slots 1-2.

[0025] The rebar spacing inspection device includes a strip-shaped main body 1, which can be made of wood or aluminum, etc. Figure 1 In the middle, the L direction is the length direction of the strip-shaped main body 1, and the W direction is the width direction of the strip-shaped main body 1.

[0026] The strip-shaped main body 1 is provided with a sliding groove 1-1, which is, for example, a rectangular structure and is provided along the length direction of the strip-shaped main body 1.

[0027] Multiple sliders 2 are slidably installed on the slide 1-1. The sliders 2 are, for example, sheet-like structures, and the number is, for example, two, three or four. The sliders 2 are set to provide a foundation for clamping the reinforcing bars. The sliders 2 can slide to change their position and at the same time change the spacing between the sliders 2.

[0028] The slide 1-1 has multiple slots 1-2 along one side of its length. These slots 1-2 can be, for example, arc-shaped or rectangular slots, and the number can be, for example, 10 or 20, without limitation. The multiple slots 1-2 are arranged at equal intervals; for example, adjacent slots 1-2 can be equally spaced, or multiple identical slots 1-2 can be connected end-to-end. The slots 1-2 cooperate with the slider 2 to conveniently restrict the position of the slider 2, improve stability, and visually determine the spacing between adjacent sliders 2.

[0029] Each slider 2 has a clamping structure 3 at one end. The clamping structure 3 can be a buckle or a clip, etc., and there is no specific limitation. The clamping structure 3 can be used in conjunction with the reinforcing bar.

[0030] Each slider 2 is also provided with a locking structure 4, which may be a buckle or nut, etc., and is not specifically limited. It can fix the position of the slider 2 and lock the slider 2 in the slot 1-2.

[0031] The device can be used by moving slider 2, determining the slider spacing, fixing slider 2 with locking structure 4, and cooperating with a clamping structure 3 with the reinforcing bar. This allows for a direct comparison of whether the reinforcing bar spacing matches the slider spacing, thus determining whether the reinforcing bar spacing meets the requirements. It is simple, convenient, and greatly improves work efficiency. Furthermore, multiple sliders 2 are provided, allowing for simultaneous detection of the spacing between multiple reinforcing bars. The slots 1-2 facilitate the restriction of slider 2 movement. Multiple slots 1-2 are arranged at equal intervals, and the slider spacing can also be easily confirmed visually through the slots 1-2.

[0032] This rebar spacing inspection device has a simple structure, is easy to manufacture, portable, and low in cost. It can intuitively and effectively verify the rebar spacing and has high work efficiency.

[0033] In some embodiments, such as Figure 1 and Figure 3 As shown, the slider 2 is located on one side of the strip-shaped body 1, and the slider 2 is provided with a vertical first bolt 2-1, which extends into the groove 1-1.

[0034] like Figure 1 As shown, slider 2 is located on one side of the strip-shaped body 1, as... Figure 3 As shown, a first bolt 2-1 perpendicular to the slider 2 is fixed on one side of the slider 2. The first bolt 2-1 can extend into the slide groove 1-1 to realize the sliding installation of the slider 2.

[0035] In some embodiments, such as Figure 2 and Figure 3 As shown, the locking structure 4 includes a first nut 4-1, which is sleeved on the first bolt 2-1. The first bolt 2-1 is used to clamp the strip-shaped body 1 and the slider 2.

[0036] like Figure 3 As shown, a first nut 4-1 is fitted onto the first bolt 2-1. The first nut 4-1 and the slider 2 can clamp the strip-shaped body 1 between them. The position of the slider 2 can be fixed by tightening the first nut 4-1, and the slider 2 can be moved or removed by loosening the first nut 4-1.

[0037] In some embodiments, the diameter of the first nut 4-1 is greater than the width of the groove 1-1.

[0038] The diameter of the first nut 4-1 is, for example, 8cm to 10cm, and the width of the slide groove 1-1 is, for example, 4cm to 6cm. For example, the diameter of the first nut 4-1 is 9cm, and the width of the slide groove 1-1 is 5cm, etc. Setting the diameter of the first nut 4-1 to be larger than the width of the slide groove 1-1 can prevent the slider 2 from falling off and ensure stability.

[0039] In some embodiments, such as Figure 4 As shown, the first bolt 2-1 passes through the slider 2, and there are two first nuts 4-1, which are respectively located at both ends of the first bolt 2-1.

[0040] like Figure 4 As shown, a through hole can be provided on the slider 2, and the first bolt 2-1 passes through the through hole. A first nut 4-1 is provided at each end of the first bolt 2-1. The two first nuts 4-1 are located on the two sides of the slider 2 respectively. In this way, the slider 2 can be fixed on the first side of the strip body 1 or the second side of the strip body 1. It can be fixed by tightening the first nuts 4-1 on both sides, making the operation more convenient.

[0041] In some embodiments, such as Figure 1 As shown, the strip-shaped body 1 has a scale line 1-3 on one side along the length direction, and the scale line 1-3 is located near the slot 1-2.

[0042] like Figure 1 As shown, a scale line 1-3 is provided on one long side of the strip-shaped main body 1. The scale line 1-3 is set close to the slot 1-2, which makes it convenient to read the slider spacing. In addition, the rebar spacing inspection device can also measure the rebar spacing. For example, the clamping structure 3 of the two sliders 2 is respectively matched with a rebar, and then the spacing between the two sliders 2 on the scale line 1-3 is read, that is, the spacing of the corresponding rebar is obtained.

[0043] In some embodiments, such as Figure 1 As shown, the slide 1-1 includes a connected blank area 1-4 and an inspection area 1-5 along the length direction, and the slot 1-2 is disposed in the inspection area 1-5.

[0044] like Figure 1 As shown, the slide 1-1 includes a blank area 1-4 and an inspection area 1-5. The inspection area 1-5 is provided with a slot 1-2, while the blank area 1-4 is not provided with a slot 1-2. The blank area 1-4 can temporarily store the slider 2 to avoid interfering with the verification operation.

[0045] In some embodiments, such as Figure 1As shown, the card slots 1-2 are arc-shaped slots, and multiple card slots 1-2 are connected end to end in sequence.

[0046] like Figure 1 As shown, slots 1-2 are arc-shaped slots and are connected end to end to facilitate the movement of slider 2.

[0047] In some embodiments, such as Figure 2 As shown, the clamping structure 3 includes two opposing arc-shaped clamping pieces 3-1, and the opening formed by the two arc-shaped clamping pieces 3-1 is located away from the strip-shaped main body 1.

[0048] like Figure 2 As shown, the clamping structure 3 includes two opposing arc-shaped clamping pieces 3-1, and the opening formed by the two arc-shaped clamping pieces 3-1 faces outward, which facilitates cooperation with the reinforcing bars.

[0049] In some embodiments, such as Figure 2 As shown, the clamping structure 3 also includes a second bolt 3-2 that passes through the two arc-shaped clamping pieces 3-1. One end of the second bolt 3-2 is provided with a limiting block 3-3, and the other end is fitted with a second nut 3-4. A spring 3-5 is fitted in the middle of the second bolt 3-2, and the spring 3-5 is located between the two arc-shaped clamping pieces 3-1.

[0050] like Figure 2 As shown, a second bolt 3-2 is installed through two arc-shaped clamping pieces 3-1. The second bolt 3-2 is positioned close to the slider 2. One end of the second bolt 3-2 has a limiting block 3-3, and the other end has a second nut 3-4. The limiting block 3-3 can be a regular nut, and the second nut 3-4 can be a wing nut. By adjusting the distance between the second nut 3-4 and the limiting block 3-3, the opening of the two arc-shaped clamping pieces 3-1 can be adjusted, thus accommodating steel bars of different sizes. A spring 3-5 is also fitted onto the second bolt 3-2. The spring 3-5 is located within the opening and abuts against the two arc-shaped clamping pieces 3-1 respectively, for resetting the arc-shaped clamping pieces 3-1.

[0051] The specific operation process of this rebar spacing inspection device is as follows: After moving slider 2 to determine the rebar spacing to be checked, slider 2 is fixed so that the slider spacing is equal to the rebar spacing to be checked. Then, the device is placed vertically above the rebar to be tested, so that a certain rebar is located in the middle position of the two arc-shaped clamps 3-1 of the same clamping structure 3. The corresponding rebar is inserted. If another rebar can also cooperate with the other clamping structure 3, it means that the spacing of the two rebars meets the rebar spacing to be checked; if the other rebar cannot be inserted into the clamping structure 3, it means that the spacing does not meet the requirements. This rebar spacing inspection device can also check the spacing of multiple rebars at the same time. For example, when checking whether three rebars are set at equal intervals, three sliders 2 can be used for inspection. The specific process is not described in detail.

[0052] This rebar spacing inspection device is lightweight and portable. It can be made of lightweight materials such as wood or aluminum plates, and its overall weight is light. Compared with traditional rebar spacing inspection tools or devices, it is more convenient for workers to carry to various construction sites, which greatly reduces the physical exertion of workers, reduces transportation costs, and improves the applicability of the device. This rebar spacing inspection device is easy to use and extremely simple to operate. Its comb-like structure and comparative testing method allow workers to operate it without complex professional training. It can quickly complete the inspection of rebar spacing on the construction site, adapting to different spacing and rebar sizes, effectively improving work efficiency, shortening construction time, and meeting the needs of large-scale construction projects.

[0053] This rebar spacing inspection device is cost-effective, significantly reducing overall costs while ensuring accurate and efficient rebar spacing detection. Compared to traditional, complex rebar spacing inspection equipment, this device offers a clear cost advantage, facilitating its widespread application in the construction industry.

[0054] This rebar spacing inspection device boasts high accuracy. Compared to traditional visual inspection methods, it provides a direct and objective basis for judging rebar spacing. By comparing the device with the rebar, it can more accurately determine whether the rebar spacing meets the standards, effectively avoiding errors caused by subjective human judgment, improving the accuracy of construction quality inspection, and ensuring the quality and safety of building structures.
