[0002] In a modern building manufacturing process, if the steel bar diameter used in a concrete structure does not meet the design or other specification requirements, the overall engineering quality cannot meet the standard, which is difficult to pass the acceptance, and also hides hidden dangers in the later period, so generally the detection of steel bars is very important.

[0003] The steel bar diameter represents the basic data of the steel bar, and the detection of the steel bar diameter is most important in the detection process. In order to ensure the representativeness and accuracy of the data, the steel bar diameter needs to be measured repeatedly 3 times at the same position, and the average value of the 3 measurement results is taken as the detection value of the steel bar diameter at the measurement point. Some steel bars also need to be compared and re-measured later, and multiple diameter detections need to be performed at multiple positions of the steel bar.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] Reference Figures 1-9 A device for detecting the diameter of reinforcing bars in construction is provided to simultaneously detect the diameter of reinforcing bars in three or more directions in multiple directions. During detection, subsequent re-inspection, and data comparison, it provides diameter data for multiple parts of the reinforcing bar, reducing errors in multiple manual operations and lowering workload. The device includes an adjustable base rod 1, comprising a base rod body and adjustable rod bodies that can extend at both ends of the base rod body. The three sections of the adjustable base rod 1 are tightly connected. Each of the three sections of the adjustable base rod 1 is equipped with an adjustable base sleeve 2. The adjustable base sleeve 2 is equipped with an installation beam 3 that allows the reinforcing bar to be inserted laterally. The installation beams 3 on the multiple adjustable base sleeves 2 are parallel to each other. Each installation beam 3 includes two parallel beam frames, with the gap between the two beam frames forming a space for the reinforcing bar insertion. Each beam frame has an installation slot along its length.

[0036] The diameter detection mechanism 4 includes a mounting slide 41, a multi-directional measuring component, and an extrusion mechanism 5. The mounting slide 41 is attached to the mounting slots of the two parallel crossbeams of the mounting beam 3 at both ends and is set between the parallel crossbeams, so that the mounting slide 41 can slide along the mounting beam 3. The multi-directional measuring component is set on the mounting slide 41 and can detect the diameter of the reinforcing bar inserted into the socket of the mounting slide 41 in multiple directions. The extrusion mechanism 5 is set inside 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 to slide along the mounting slot on the mounting beam 3.

[0037] Among them, the ends of the two sections of the crossbeam 3 are provided with external bending frames for guiding the insertion of reinforcing bars. The mounting slide 41 has an insertion port that fits the edge of the two sections of the crossbeam 3, so that the reinforcing bar can pass laterally through the gap between the two sections of the crossbeam 3 and be inserted into the insertion port 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 reinforcing bar to be tested.

[0038] The adjustable base 2 and other diameter detection structures arranged on the adjustable base 2 can be arranged on the three rod bodies of the adjustable base rod 1 in an adjustable manner, and the minimum number is one on each of the three rod bodies. When the diameters of more than three parts of the same steel bar need to be detected, different numbers of adjustable bases 2 and other diameter detection structures arranged on the adjustable bases 2 can be arranged on the rod bodies of the adjustable base rod 1, so that more than three diameter detection structures are arranged on the rod bodies of the adjustable base rod 1, the diameters of more parts of the steel bar to be detected are detected, and more abundant diameter detection data is obtained. At the same time, the positions of the adjustable bases 2 and the diameter detection structures on the adjustable base rod 1 can be adjusted according to actual needs. At the same time, since the length of the adjustable base rod 1 can be lengthened, when the diameters of high steel bars need to be measured, 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.

[0039] The multi-directional measurement assembly includes a first measurement assembly 42, a second measurement assembly 43, and a central measurement assembly 44. The first measurement assembly 42 is arranged at the end of the mounting slide 41, the second measurement assembly 43 is arranged at the bottom end of the mounting slide 41, and the central measurement assembly 44 is arranged at the center of the mounting slide 41 and is attached to the inner side of the mounting slot of one of the frame bodies of the mounting cross beam 3. The first measurement assembly 42 is mirror-symmetrical to the second measurement assembly 43, and the detection directions of the first measurement assembly 42 and the second measurement assembly 43 are the same. The detection direction of the central measurement assembly 44 is perpendicular to the detection directions of the first measurement assembly 42 and the second measurement assembly 43, so that the first measurement assembly 42, the second measurement assembly 43, and the central measurement assembly 44 can detect the diameters of the steel bars inserted into the mounting slide 41 in multiple directions.

[0040] The first measuring assembly 42 and the second measuring assembly 43 are the same in structure, the first measuring assembly 42 comprises a positioning horizontal plate 421, an extrusion assembly 422, a reinforcing steel outer ring frame 423, a scale and a diameter detecting piece 6, the positioning horizontal plate 421 is fixedly arranged on the mounting sliding seat 41, the positioning horizontal plate 421 is provided with a through groove, the reinforcing steel outer ring frame 423 is a concave frame, one side of the frame body of the reinforcing steel outer ring frame 423 is arranged in close contact with the outer wall edge of the mounting sliding seat 41 and the inner wall of the through groove, and the two sides of the vertical frame body of the reinforcing steel outer ring frame 423 are arranged in close contact with the opening edge of the mounting sliding seat 41, the extrusion assembly 422 is arranged in the through groove of the positioning horizontal plate 421, and the extrusion assembly 422 acts on the reinforcing steel outer ring frame 423, so that the reinforcing steel outer ring frame 423 can move horizontally at the opening of the mounting sliding seat 41, the scale is arranged between the two sides of the vertical frame body of the reinforcing steel outer ring frame 423, and the edge of the scale is arranged in close contact with the vertical frame body on the side of the reinforcing steel outer ring frame 423 close to the extrusion assembly 422, the diameter detecting piece 6 is arranged on the vertical frame body on one side of the reinforcing steel outer ring frame 423, and the detection end of the diameter detecting piece 6 keeps facing the moving trend of the vertical frame body on the other side of the reinforcing steel outer ring frame 423, when the reinforcing steel to be measured is inserted horizontally into the opening of the mounting sliding seat 41, the vertical frame body on one side of the reinforcing steel outer ring frame 423 is arranged in close contact with one side of the reinforcing steel through the extrusion of the extrusion assembly 422, at this time, the other side of the reinforcing steel is extruded by the diameter detecting piece 6, and the reading of the diameter of the reinforcing steel to be measured can be obtained through the scale, and the diameter detection is completed.

[0041] Further, the edges of the vertical frame bodies on the two sides of the reinforcing steel outer ring frame 423 are curved outward, so that the opening of the reinforcing steel outer ring frame 423 keeps an open state, when the reinforcing steel to be measured is inserted, the reinforcing steel outer ring frame 423 can be rotated to be arranged in close contact with the outer side of the reinforcing steel to be measured through the extrusion of the curved frame body by the reinforcing steel, at this time, the reinforcing steel to be measured can be guided into the concave part of the reinforcing steel outer ring frame 423 through the curved frame body, and the diameter detecting piece 6 can more conveniently perform subsequent diameter detection.

[0042] Further, the diameter detecting member 6 comprises a movable extruding frame 601, a stop ring 602 and a stop spring 603. The movable extruding frame 601 is movably arranged on the vertical frame body on one side of the reinforcing steel bar outer ring frame 423, and the side edge of the movable extruding frame 601 is opposite to the scale. The stop ring 602 is arranged at the connecting position of the movable extruding frame 601 and the reinforcing steel bar outer ring frame 423, and the stop ring 602 is tightly connected with the movable extruding frame 601. The stop spring 603 is arranged between the movable extruding frame 601 and the outer wall of the vertical frame body of the reinforcing steel bar outer ring frame 423, and the stop spring 603 acts on the movable extruding frame 601, so that the movable extruding frame 601 keeps the tendency of sliding along the outer wall of the vertical frame body of the reinforcing steel bar outer ring frame 423. Under the cooperation of the stop ring 602 and the stop spring 603, the movable extruding frame 601 can be immediately stopped after sliding, so as to prevent the gap between the movable extruding frame 601 and the steel bar to be measured due to the shaking of the frame body, and affect the accuracy of the diameter measurement. When the steel bar to be measured is transversely inserted into the opening of the mounting slide 41, the steel bar to be measured will extrude the movable extruding frame 601 to slide outward. At this time, the stop spring 603 is compressed, and the stop ring 602 stops the movable extruding frame 601. Under the stopping action of the stop ring 602 and the stop spring 603, the movable extruding frame 601 is attached to the outer side 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 body of the positioning horizontal plate 421, and the other side is tightly attached by the movable extruding frame 601. The diameter of the steel bar to be measured can be obtained by reading the edge of the movable extruding frame 601 opposite to the scale.

[0043] The central measuring assembly 44 comprises a connecting slide 441, a back-pulling detection frame 442, a side-moving top frame 7 and a scale. The connecting slide 441 is arranged on one side of the mounting slide 41. The back-pulling detection frame 442 is arranged on the connecting slide 441 and attached to the inner side of the mounting slot of one of the frame bodies of the mounting beam 3. The back-pulling detection frame 442 is a frame body pulled back by a spring, which will not be described here. The side-moving top frame 7 is arranged at the end of the back-pulling detection frame 442, and one side of the frame body of the side-moving top frame 7 is transversely arranged between the two frame bodies of the mounting beam 3. The scale is arranged on the outer side of the connecting slide 441, and the side edge of the scale is parallel to the innermost side of the opening of the mounting slide 41. The length direction of the scale is parallel to the sliding direction of the back-pulling detection frame 442. When the steel bar to be measured is inserted into the mounting slide 41, the steel bar will first extrude the side-moving top frame 7 to move sideways and enter the mounting slide 41. At this time, under the pulling of the back-pulling detection frame 442, the side-moving top frame 7 will slide back and extrude the steel bar to tightly attach to the innermost side of the mounting slide 41. At this time, the diameter of the steel bar to be measured at this position can be read by reading the position reading of the side-moving top frame 7 on the scale.

[0044] Further, the side-moving top frame 7 comprises a connecting top plate 701, an arc edge sliding block 702 and a reset spring 703. The connecting top plate 701 is arranged at the end of the back-pulling detection frame 442. The arc edge sliding block 702 is horizontally slidingly arranged on the connecting top plate 701. The reset spring 703 is arranged between the arc edge sliding block 702 and the connecting top plate 701. When the reinforcing steel bar is inserted into the opening of the mounting sliding seat 41, the arc edge sliding block 702 is pressed to slide sideways. After the reinforcing steel bar is completely inserted, the arc edge sliding block 702 slides back under the elastic force of the reset spring 703 and tightly abuts against the outer wall of the reinforcing steel bar under the pulling of the back-pulling detection frame 442, thereby completing the detection of the diameter of the reinforcing steel bar.

[0045] In addition, the extruding mechanism 5 comprises a guide rod 501 and an extruding spring 502. The guide rod 501 is arranged between the two segments of the mounting beam 3 and one end of the guide rod 501 is fixedly connected with the adjustable base sleeve 2. The extruding spring 502 is arranged around the outer side of the guide rod 501 and one end of the extruding spring 502 is fixedly connected with the adjustable base sleeve 2 and the other end is connected with the mounting sliding seat 41. When the reinforcing steel bar to be detected is inserted into the mounting sliding seat 41 in the transverse direction, the mounting sliding seat 41 tightly abuts against the reinforcing steel bar to be detected under the extrusion of the extruding spring 502, thereby facilitating the detection of the diameter of the reinforcing steel bar to be detected.
