Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, and in particular to a steel bar sample inspection tool. Background Technology

[0002] Drawing detailed drawings of reinforcing bars on the ground is a very traditional skill in reinforcing bar processing. The steps are as follows: based on the location of the reinforcing bar processing machinery, use paint to draw a 1:1 scale marking line on the nearby ground corresponding to the shape and size of the reinforcing bar. Then, place the reinforcing bar to be inspected at the marking line position and compare the shape and size difference between the reinforcing bar to be inspected and the marking line to determine whether the reinforcing bar to be inspected meets the requirements.

[0003] Because some of the steel bars are large, the sprayed marking lines require a lot of space. When other processes are needed on site, the material transport and personnel trampling on the marking lines will damage the marking lines on the ground, resulting in incomplete detailed drawings that lose their guiding function. Once covered or damaged, the detailed drawings cannot be saved and reused, and need to be redrawn, which will consume extra time and manpower. Utility Model Content

[0021] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0022] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0023] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0024] The present invention will now be described in conjunction with the accompanying drawings and specific embodiments: Combination Figure 1 and Figure 2 This utility model provides a tool for inspecting large-scale steel bars, including at least two acrylic plates 1, wherein at least a portion of the acrylic plates 1 are provided with grooves 2, and at least two acrylic plates 1 can be spliced ​​together to form a detection groove 3 with multiple grooves 2. The detection groove 3 can be used for inspecting large-scale steel bars.

[0025] Several acrylic sheets 1 are spliced ​​together to form a testing plate. Testing grooves 3 are located on the testing plate. Each testing groove 3 is adapted to the outer contour of a specific reinforcing bar to be tested and the testing groove 3 is continuous along its own length, so that the reinforcing bar to be tested can be placed into the testing groove 3 for large-scale testing of the reinforcing bar. This helps quality inspectors quickly determine whether the reinforcing bar to be tested meets the construction standards, improving the quality and efficiency of testing. The testing plate is formed by splicing several acrylic sheets 1, which can reduce the size of a single sheet, making it easy to move and store. It is also convenient to cut grooves 2 into a single acrylic sheet 1.

[0026] In an alternative embodiment, the groove 2 extends to the end opening at the edge of the acrylic plate 1 to mate with the open end of another groove 2 on the adjacent acrylic plate 1, thereby forming a longer detection groove 3.

[0027] In an optional embodiment, the width of the detection groove 3 is adapted to the width of the reinforcing bar to be tested; further, the width of the detection groove 3 is slightly larger than the width of the reinforcing bar to be tested. Quality inspectors can put the reinforcing bar to be tested into the detection groove 3 from the opening at the top of the detection groove 3, and then quickly determine whether the width of the reinforcing bar to be tested meets the requirements by observing the gap between the reinforcing bar to be tested and the side wall of the detection groove 3.

[0028] In an optional embodiment, the depth of the detection groove 3 is adapted to the height of the reinforcing bar to be tested, and the bottom surface of the detection groove 3 is flush with it; further, the depth of the detection groove 3 is the same as the height of the reinforcing bar to be tested; for planar reinforcing bars, their flatness is also an important factor in quality inspection. In the prior art, the flatness of the reinforcing bar to be tested is judged by placing it on the ground and observing its contact with the ground. This requires quality inspectors to bend over to observe, which is quite laborious. In this embodiment, the depth of the detection groove 3 is set to be adapted to the height of the reinforcing bar to be tested, which makes it convenient for quality inspectors to judge the flatness of the reinforcing bar to be tested by observing the height of the reinforcing bar to be tested relative to the surface of the acrylic plate 1. In addition to being observed with the naked eye, the height of the reinforcing bar to be tested relative to the surface of the acrylic plate 1 can also be perceived by sliding the palm along the length of the detection groove 3, which improves the detection efficiency and accuracy.

[0029] For the reinforcing bars to be tested with a circular cross-section, their height and width are equal and are both the diameter of the circular cross-section.

[0030] In an optional embodiment, the thickness of the acrylic plate 1 is greater than the depth of the detection groove 3, so that the detection groove 3 will not penetrate the acrylic plate 1, which helps to improve the rigidity of the acrylic plate 1 and reduce deformation. At the same time, the bottom of the detection groove 3 can play a certain protective role for the steel bar to be tested, reducing the probability of the steel bar to be tested being scratched.

[0031] In an optional embodiment, the shape and length of the detection groove 3 are adapted to the shape and length of the reinforcing bar to be tested, respectively. Quality inspectors can determine whether the reinforcing bar to be tested meets the shape and length requirements by observing whether the reinforcing bar to be tested can be completely embedded in the detection groove 3 and the difference in size between the reinforcing bar to be tested and the detection groove 3.

[0032] The matching of shape and length means that the detection groove 3 corresponds to the outer contour of the reinforcing bar to be detected in a 1:1 ratio. For example, for a reinforcing bar to be detected with a first reinforcing bar segment and a second reinforcing bar segment that are inclined to each other, the detection groove 3 has a first detection groove segment with the same or similar length as the first reinforcing bar segment and a second detection groove segment with the same or similar length as the second reinforcing bar segment, and the included angle between the first detection groove segment and the second detection groove segment is the same or similar to the included angle between the first reinforcing bar segment and the second reinforcing bar segment.

[0033] When in use, the reinforcing bar to be tested is placed in the testing groove 3. The shape, size and flatness of the reinforcing bar to be tested can be judged based on whether it can be placed, the gap between the reinforcing bar to be tested and the testing groove 3, and the height of the top surface of the reinforcing bar to be tested relative to the surface of the acrylic plate 1.

[0034] In some embodiments, to ensure accurate docking between adjacent acrylic sheets 1, a positioning structure is provided on the side of the acrylic sheet 1, and adjacent acrylic sheets 1 are positioned and connected through the positioning structure. Further, combined with... Figure 3 and Figure 4 The acrylic sheet 1 has positioning protrusions 4 and positioning grooves 5 on opposite sides. One acrylic sheet 1 is positioned with another adjacent acrylic sheet 1 by fitting the positioning protrusions 4 and positioning grooves 5. Exemplarily, the positioning protrusions 4 can be cylindrical protrusions protruding from the side wall of the acrylic sheet 1, and the positioning grooves 5 can be cylindrical grooves provided on the side wall of the acrylic sheet 1. The cylindrical protrusions and cylindrical grooves are sized to match. In order to reduce torsional misalignment, each side wall of the acrylic sheet 1 has at least two positioning protrusions 4 or positioning grooves 5 spaced apart.

[0035] In some embodiments, the detection groove 3 includes at least two connected groove segments with an included angle between adjacent groove segments, so that it can be used to detect reinforcing bars with bent sections.

[0036] In an optional embodiment, since the bent detection groove 3 leaves a lot of empty space, in order to improve the space utilization of the detection plate, the detection plate is provided with at least two different detection grooves 3, and different detection grooves 3 can be used to detect steel bars of different specifications.

[0037] In an optional implementation, to facilitate quality inspectors in obtaining information about each testing slot 3, the model number of the reinforcing bar to be tested is marked next to each testing slot 3. Exemplarily, the information can be clearly marked on the acrylic sheet 1 using stickers or engraving.

[0038] In some embodiments, the acrylic sheet 1 is made of transparent material; by selecting a transparent acrylic sheet 1, quality inspectors can clearly observe the fit between the reinforcing bar and the groove 2 from the side and above through the acrylic sheet 1, thereby quickly determining whether the reinforcing bar is qualified and reducing the risk of misjudgment.

[0039] In one alternative implementation, such as Figures 1 to 4 As shown in the figure, the testing plate is composed of four acrylic plates 1. Two different shaped testing grooves 3 are opened on the testing plate, which can be used for different steel bar testing. Each acrylic plate 1 has a groove 2. The top surface of the groove 2 is open and the groove 2 extends to the end of the side of the acrylic plate 1.

[0040] In one optional manufacturing method, several acrylic sheets 1 are first laid on a flat site, and adjacent acrylic sheets 1 are spliced ​​together to form a whole inspection board. A detailed drawing of the reinforcing bars is drawn on the inspection board. Then, the inspection board is divided into several acrylic sheets 1, and corresponding grooves 2 are engraved according to the markings on each acrylic sheet 1. A high-precision caliper is used to check whether the dimensions of the grooves 2 are correct, and the corresponding reinforcing bar information is clearly marked on the board by means of stickers or engraving.

[0041] When it is necessary to test the reinforcing bars, several acrylic sheets 1 are laid and spliced ​​on a flat site so that the grooves 2 on different acrylic sheets 1 are assembled into test grooves 3. The processed reinforcing bars are placed horizontally into the corresponding test grooves 3. All parts of the reinforcing bars should be able to fall naturally into the test grooves 3 and basically fit the outline of the test grooves 3 without obvious visible gaps or protrusions. This is considered as qualified. When other processes need to be carried out on site, several acrylic sheets 1 are disassembled and put away, and taken out again when needed next time.

[0042] The rebar detail inspection tool described in this embodiment features inspection slots 3 on an inspection plate. By placing the rebar to be inspected into the inspection slots 3, the shape, size, and flatness of the rebar can be quickly and intuitively checked, significantly reducing inspection time for both operators and quality inspectors. The inspection plate is composed of several acrylic sheets 1, each small and easily movable. The inspection slots 3 are composed of several grooves 2, located on the acrylic sheets 1, allowing the inspection slots 3 to move and be stored with the acrylic sheets 1. This avoids the manpower waste and quality risks associated with repeatedly drawing rebar detail diagrams. This tool provides real-time feedback on inspection results, facilitating timely adjustment or replacement of substandard rebars by on-site workers, improving inspection efficiency, reducing quality risks, and achieving low-cost, high-precision, and high-efficiency quality control.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
