Technical Field

[0001] The present invention relates to the technical field of steel bar diameter detection, and in particular to a device and method for detecting the diameter of building steel bars. Background Art

[0002] In the modern building manufacturing process, if the diameter of the steel bars used in the concrete structure does not meet the design or other specification requirements, the overall project quality will not meet the standards. Not only will it be difficult to pass the acceptance, but it will also pose hidden dangers in the later stage. Therefore, the inspection of steel bars is generally taken very seriously.

[0003] The diameter of the steel bar represents the basic data of the steel bar. The detection of the steel bar diameter is of utmost importance during the detection process. When detecting the steel bar diameter, in order to ensure the representativeness and accuracy of the data, it is necessary to repeat the measurement three times at the same location and take the average value of the three measurement results as the detection value of the steel bar diameter at the measuring point. Some steel bars also need later comparison and re-measurement, and it is often necessary to perform multiple diameter detections at multiple positions of the steel bar.

[0004] In the process of detecting the diameter of steel bars, the same point of the steel bar needs to be measured three times to obtain the average value, and multiple positions need to be tested at the same time.

An adjustable base rod 1 is provided here, the adjustable base rod 1 includes a basic rod body and adjustable rod bodies that can be extended at both ends of the basic rod body, the three sections of the adjustable base rod 1 are tightly connected, and the three sections of the adjustable base rod 1 are all provided with adjustable base sleeves 2, and the adjustable base sleeves 2 are provided with mounting crossbeams 3 that allow the steel bars to be inserted laterally. The mounting crossbeams 3 on the multiple adjustable base sleeves 2 are parallel to each other, and the mounting crossbeams 3 include two parallel crossbeam frames, and the gap between the two crossbeam frames forms a space for the steel bars to be inserted, and the two crossbeam frames are both provided with mounting slots along their length directions; The diameter detection mechanism 4 includes a mounting slide 41, a multi-directional measuring component and an extrusion mechanism 5. The two ends of the mounting slide 41 are fitted with the mounting slots of the two parallel beam frames of the mounting beam 3 and are arranged between the parallel beam frames, so that the mounting slide 41 can slide along the mounting beam 3. The multi-directional measuring component is arranged on the mounting slide 41, and the multi-directional measuring component can detect the diameter of the steel bar inserted into the socket of the mounting slide 41 in multiple directions. The extrusion mechanism 5 is arranged on the inner side of the mounting beam 3, and the end of the extrusion mechanism 5 acts on the mounting slide 41, so that the mounting slide 41 maintains the tendency of sliding outward along the mounting slot on the mounting beam 3; Among them, the ends of the two sections of the beam frame of the mounting beam 3 are provided with outer bending frames for guiding the insertion of steel bars, and the mounting slide 41 is provided with a socket that fits the edges of the two sections of the beam frame, so that the steel bars can pass laterally through the gap between the two sections of the frame of the mounting beam 3 and be inserted into the socket of the mounting slide 41. Through the action of the extrusion mechanism 5, the mounting slide 41 can be squeezed to fit tightly against the outside of the steel bar to be tested.

[0022] The adjustable base sleeve 2 and other structures for diameter detection arranged on the adjustable base sleeve 2 are adjustable in number on the three rod bodies of the adjustable base rod 1, with a minimum of one for each of the three rod bodies. When it is necessary to detect the diameters of more than three parts of the same steel bar to be measured, different numbers of adjustable base sleeves 2 and other detection structures on the adjustable base sleeve 2 can be arranged on the rod body of the adjustable base rod 1, thereby setting more than three diameter detection structures on the rod body of the adjustable base rod 1, thereby realizing diameter detection of more parts of the steel bar to be measured and obtaining richer diameter detection data. At the same time, the positions of the adjustable base sleeve 2 and the diameter detection structure on the adjustable base rod 1 can also be adjusted according to actual needs. At the same time, since the length of the adjustable base rod 1 can be lengthened, when it is necessary to measure high steel bars, the adjustable base rod 1 can be lengthened, so that the measurement personnel can complete the diameter measurement of the high steel bars without the aid of other tools.

[0023] The multi-directional measuring component includes a first measuring component 42, a second measuring component 43 and a central measuring component 44. The first measuring component 42 is arranged at the end of the mounting slide 41, the second measuring component 43 is arranged at the bottom of the mounting slide 41, and the central measuring component 44 is arranged at the center of the mounting slide 41, and the central measuring component 44 is in contact with the inner side of one of the frame mounting slots of the mounting beam 3. The first measuring component 42 and the second measuring component 43 are mirror-symmetrical, and the first measuring component 42 and the second measuring component 43 have the same detection direction. The detection direction of the central measuring component 44 is perpendicular to the detection direction of the first measuring component 42 and the second measuring component 43, so that the first measuring component 42, the second measuring component 43 and the central measuring component 44 can perform multi-directional detection on the diameter of the steel bar inserted into the mounting slide 41.

[0024] The first measuring component 42 has the same structure as the second measuring component 43. The first measuring component 42 includes a positioning transverse plate 421, an extrusion component 422, a steel bar outer ring frame 423, a scale and a diameter detection member 6. The positioning transverse plate 421 is fixedly arranged on the mounting slide 41. A through groove is provided on the positioning transverse plate 421. The steel bar outer ring frame 423 is a concave frame. One side of the frame body of the steel bar outer ring frame 423 is arranged in contact with the outer wall edge of the mounting slide 41 and the inner wall of the through groove, and the vertical frames on both sides of the steel bar outer ring frame 423 are arranged in contact with the opening edge of the mounting slide 41. The extrusion component 422 is arranged in the through groove of the positioning transverse plate 421, and the extrusion component 422 acts on the steel bar outer ring frame 423, so that the steel bar outer ring frame 42 The opening of the mounting slide 41 can be moved horizontally, the scale is set between the vertical frames on both sides of the steel bar outer ring frame 423, and the edge of the scale fits the vertical frame on one side of the steel bar outer ring frame 423 close to the extrusion assembly 422, the diameter detection member 6 is set on the vertical frame on one side of the steel bar outer ring frame 423, and the detection end of the diameter detection member 6 keeps facing the movement trend of the vertical frame on the other side of the steel bar outer ring frame 423. When the steel bar to be tested is inserted horizontally into the opening of the mounting slide 41, the vertical frame on one side of the steel bar outer ring frame 423 fits one side of the steel bar through the extrusion of the extrusion assembly 422. At this time, the diameter detection member 6 squeezes the other side of the steel bar, and the reading of the diameter of the steel bar to be tested can be obtained through the scale, completing the diameter detection.

[0025] Furthermore, the edges of the vertical frames on both sides of the steel bar outer ring frame 423 are bent outward, so that the opening of the steel bar outer ring frame 423 remains open. When the steel bar to be tested is inserted, the steel bar can squeeze the bent frame to allow the steel bar outer ring frame 423 to rotate to fit the outside of the steel bar to be tested. At this time, the steel bar to be tested can be guided into the concave part of the steel bar outer ring frame 423 through the bent frame, which makes it more convenient for the diameter detection part 6 to perform subsequent diameter detection.

[0026] Furthermore, the diameter detection part 6 includes a movable extrusion frame 601, a stop ring 602 and a stop spring 603. The movable extrusion frame 601 is movably inserted on the vertical frame body on one side of the steel bar outer ring frame 423, and the edge of one side of the movable extrusion frame 601 is facing the scale. The stop ring 602 is set at the connection between the movable extrusion frame 601 and the steel bar outer ring frame 423, and the stop ring 602 is tightly connected to the movable extrusion frame 601. The stop spring 603 is set between the movable extrusion frame 601 and the outer wall of the vertical frame of the steel bar outer ring frame 423, and the stop spring 603 acts on the movable extrusion frame 601, so that the movable extrusion frame 601 maintains a tendency to slide inward along the outer wall of the vertical frame of the steel bar outer ring frame 423, and the stop ring 602 and the stop spring 603 3, the movable extrusion frame 601 can stop immediately after sliding, so as to prevent a gap from being generated between the movable extrusion frame 601 and the steel bar to be measured due to the shaking of the frame body, thereby affecting the accuracy of diameter measurement. When the steel bar to be measured is horizontally inserted into the opening of the mounting slide 41, the steel bar to be measured will squeeze the movable extrusion frame 601 and slide outward. At this time, the stop spring 603 is compressed, and the stop ring 602 stops the movable extrusion frame 601. Under the stopping action of the stop ring 602 and the stop spring 603, the movable extrusion frame 601 is attached to the outside of the steel bar to be measured. At this time, one side of the steel bar to be measured is attached to the vertical frame of the positioning cross plate 421, and the other side is tightly attached by the movable extrusion frame 601. The diameter of the steel bar to be measured can be obtained by the movable extrusion frame 601 facing the edge of the scale.

[0027] The central measuring assembly 44 includes a connecting slider 441, a pull-back detection frame 442, a side-shifting top frame 7 and a scale. The connecting slider 441 is arranged on one side of the mounting slide 41, the pull-back detection frame 442 is arranged on the connecting slider 441, and is in contact with the inner side of one of the frame mounting slots of the mounting crossbeam 3. The pull-back detection frame 442 is a frame that is pulled back by a spring, and is not described in detail here. The side-shifting top frame 7 is arranged at the end of the pull-back detection frame 442, and one side of the frame of the side-shifting top frame 7 is horizontally placed between the two frames of the mounting crossbeam 3. The scale is arranged On the outside of the connecting slider 441, one side edge of the scale is parallel to the innermost side of the opening of the mounting slide 41, and the length direction of the scale is parallel to the sliding direction of the pull-back detection frame 442. When the steel bar to be measured is inserted into the mounting slide 41, the steel bar will first squeeze the side-shifting top frame 7 and move sideways and enter the mounting slide 41. At this time, under the pull of the pull-back detection frame 442, the side-shifting top frame 7 slides back and squeezes the steel bar close to the innermost side of the mounting slide 41. At this time, by reading the position reading of the side-shifting top frame 7 on the scale, the diameter of the steel bar to be measured at this location can be read.

[0028] Furthermore, the side-shifting top frame 7 includes a connecting top plate 701, an arc-edge slider 702 and a reset spring 703. The connecting top plate 701 is arranged at the end of the pull-back detection frame 442, and the arc-edge slider 702 is horizontally slidably installed on the connecting top plate 701. The reset spring 703 is arranged between the arc-edge slider 702 and the connecting top plate 701. When the steel bar is inserted into the opening of the mounting slide 41, the arc-edge slider 702 will be squeezed to slide sideways. When the steel bar is fully inserted, under the elastic force of the reset spring 703, the arc-edge slider 702 will slide back and cling to the outer wall of the steel bar under the pull of the pull-back detection frame 442, thereby completing the detection of the steel bar diameter.

[0029] In addition, the extrusion mechanism 5 includes a guide rod 501 and an extrusion spring 502. The guide rod 501 is arranged between the two sections of the mounting beam 3, and one end of the guide rod 501 is fixedly connected to the adjustable base sleeve 2. The extrusion spring 502 is arranged around the outside of the guide rod 501, and one end of the extrusion spring 502 is fixedly connected to the adjustable base sleeve 2, and the other end is connected to the mounting slide 41. When the steel bar to be tested is horizontally inserted into the mounting slide 41, under the extrusion of the extrusion spring 502, the mounting slide 41 is close to the steel bar to be tested, which is convenient for the diameter detection of the steel bar to be tested.

[0030] When the steel bar to be measured is inserted into the opening of the installation slide 41, the steel bar to be measured will be inserted into the opening of the installation slide 41. During the process, the steel bar to be measured will first squeeze the arc edge slider 702 and slide sideways. After the steel bar is inserted into the opening of the installation slide 41, the arc edge slider 702 will slide back under the elastic force of the reset spring 703. At this time, the arc edge slider 702 will be pulled back to the outer wall of the steel bar under the pull-back detection frame 442. The diameter detection of the steel bar in one direction is completed and the reading is completed through the scale on the outside of the connecting slider 441. When the steel bar to be measured is inserted into the opening of the installation slide 41, the steel bar to be measured will squeeze the edge outer wall of the vertical frame on both sides of the steel bar outer ring frame 423. Bend and insert into the steel bar outer ring frame 423. At this time, under the extrusion of the extrusion component 422, the vertical frame on one side of the steel bar outer ring frame 423 will squeeze the outer wall of one side of the steel bar to be measured, and the movable extrusion frame 601 will be squeezed on the outer wall of the other side of the steel bar to be measured under the action of the stop ring 602 and the stop spring 603. The reading is completed through the scale between the vertical frames on both sides of the steel bar outer ring frame 423 to complete the detection of the steel bar diameter in another direction. The first measuring component 42 and the second measuring component 43 have the same structure and are respectively on the upper and lower sides of the mounting slide 41, so that the steel bar to be measured can complete diameter detection in three directions on the mounting slide 41, and the average diameter value of the part of the steel bar can be directly obtained. At the same time, by detecting the steel bar diameters of the three parts of the steel bar to be measured, the steel bar diameter values ​​on the three parts can be obtained. There is no need for the staff to repeat the operation many times, which reduces human errors and workload, and can also provide more steel bar diameter data in subsequent re-inspections and data comparisons.

[0031] A method for detecting the diameter of a steel bar using a construction steel bar diameter detection device, the method steps are as follows: S1, first pull the two ends of the adjustable base rod 1 according to the length of the steel bar to be measured, and adjust the length of the adjustable base rod 1 to adapt to the length of the steel bar to be measured. After completion, insert the mounting crossbeam 3 on the three-section rod body of the entire adjustable base rod 1 into the outside of the steel bar to be measured, and let the three parts of the steel bar to be measured be laterally inserted into the mounting slides 41 on the inner sides of the three mounting crossbeams 3. At this time, under the action of the extrusion mechanism 5, the mounting slide 41 is squeezed to be close to the outside of the steel bar to be measured; S2, when the steel bar to be tested is partially inserted into the installation slide 41, when the steel bar to be tested is horizontally inserted into the opening of the installation slide 41, the steel bar to be tested will first squeeze the arc edge slider 702 to slide sideways, and when the steel bar is fully inserted, the arc edge slider 702 will slide back under the elastic force of the reset spring 703. At this time, the arc edge slider 702 will be pulled close to the outer wall of the steel bar under the pull-back detection frame 442, completing the detection of the diameter of the steel bar in one direction and completing the reading through the scale; S3, when the steel bar to be tested is inserted into the opening of the mounting slide 41, the steel bar to be tested will squeeze the vertical frames on both sides of the steel bar outer ring frame 423 to open. At this time, under the extrusion of the extrusion component 422, the frame body on one side of the steel bar outer ring frame 423 will squeeze the outer wall of one side of the steel bar to be tested, and the movable extrusion frame 601 will be squeezed on the outer wall of the other side of the steel bar to be tested under the action of the stop ring 602 and the stop spring 603, and the reading is completed through the scale between the vertical frames on both sides of the steel bar outer ring frame 423, completing the detection of the steel bar diameter in the other direction, and the first measuring component 42 and the second measuring component 43 are structurally similar.
