Description

Technical Field

[0001] The invention relates to the technical field of detection, and in particular to a steel bar on-site detection device used for construction engineering management. Background Art

[0002] The bending performance of steel bars is one of the important indicators for evaluating the durability and safety of steel bars in building structures. Steel bars may need to be bent during construction to adapt to different design requirements. Therefore, the bending performance of steel bars is directly related to the safety and stability of the structure. The surface of the steel bar is usually designed with a spiral raised pattern. The pattern on the steel bar helps to improve the bond between it and the concrete. Steel bars with patterns are usually called rebars. Common steel bar patterns include two vertical ribs extending along the axis of the steel bar. The two vertical ribs are distributed at the two end points of the steel bar diameter, dividing the steel bar surface into two semicircular arc surfaces; multiple spiral spiral ribs are distributed on the two arc surfaces along the axis of the steel bar.

[0003] In the prior art, for example, the Chinese patent with the announcement number CN116499856B, entitled A steel bar bending performance detection device and detection method, states in the public technical solution that the steel bars are embedded into the support components on both sides and installed in the limit grooves. The limit grooves can be used to limit the steel bars, and the clamping wheels on both sides can fix the steel bars. Then, the pressure device on the upper side drives the pressure rod and the pressure block to generate downward pressure to bend the steel bars. During the steel bar bending process, due to the presence of the raised pattern on the surface of the steel bar, the pressure block may cause the steel bar to slide with the hydraulic head when the steel bar is first squeezed, causing the steel bar to rotate, thereby affecting the detection effect. Summary of the invention

[0007] The fixed plate is a spiral plate spiraling around the axis of the support tube; the fixed plate is arranged in the support tube; the cross-section of the fixed plate is conical with the small end facing the inner wall of the support tube; the small end of the fixed plate is fixed on the inner wall of the support tube; the fixed plate and the support tube form a spiral adjustment groove with the opening facing the axis of the support tube; the cross-section of the adjustment groove is trapezoidal with the small end facing the axis of the support tube.

[0008] There are multiple limit assemblies, which are evenly distributed along the spiral direction of the fixed plate; the limit assemblies include a slide groove and a slide plate; the slide groove is arranged on the side wall of the large end of the fixed plate; the slide groove is a spiral groove extending along the spiral direction of the fixed plate; the slide plate is slidably installed in the slide groove; two slide seats are arranged on the slide plate; the two slide seats are distributed axially along the support tube; a ball is provided at a ball joint at one end of the slide seat close to the axis of the support tube; the slide seat is slidably installed on the slide plate along the axis direction of the support tube, and a spring is fixedly connected between the two slide seats; the spring keeps the two slide seats away and pushes the slide seat to the opening of the adjustment groove.

[0009] The adjusting component is arranged in the adjusting groove; the two ends of the steel bar are inserted into the supporting tube, and the two vertical ribs on the steel bar are distributed vertically. The adjusting component drives the slide plate to spirally slide on the fixed plate, driving the pressure balls to gather toward the vertical ribs of the steel bar, so that part of the pressure balls abut against the vertical ribs of the steel bar, so as to apply a rotational force to the steel bar through the vertical ribs, and the rotational forces applied by the two supporting tubes on the two ends of the steel bar are opposite, so as to limit the vertical ribs of the steel bar, so that the two vertical ribs on the steel bar remain distributed vertically. At the same time, the adjusting component drives the two slide seats on the same slide plate to approach, so that the two pressure balls on part of the slide plate are clamped on both sides of the spiral ribs on the steel bar, thereby increasing the rotation resistance of the steel bar, helping to prevent the steel bar from rotating in the early stage of being compressed and bent, and improving the detection effect.

[0010] Furthermore, one end of the slide seat away from the axis of the support tube is hemispherical.

[0011] Furthermore, the adjustment component includes an adjustment plate and a guide structure; the adjustment plate is spirally arranged in the adjustment groove; the adjustment plate is an elastic plate; the cross-section of the adjustment plate is a straight line along the axis direction of the support tube; one end of the adjustment plate close to the symmetry center of the two support columns is fixed on the inner wall of the support tube, and the end away from the symmetry center of the two support columns is set as a movable end; a turntable is fixed to the movable end of the adjustment plate; the turntable is rotatably installed on the inner wall of the support tube; an adjustment motor is provided at the end of the turntable away from the adjustment plate; the adjustment motor is fixed on the support tube; the output shaft of the adjustment motor is fixedly connected to the turntable; the turntable drives the end of the adjustment plate close to the adjustment motor to rotate around the support tube along the spiral direction of the adjustment plate, and the adjustment plate drives the slide plate to rotate around the axis of the support tube through the guide structure, and when the turntable drives the end of the adjustment plate close to the adjustment motor to rotate around the support tube along the spiral direction of the adjustment plate, the rotation of the movable end of the adjustment plate drives the spiral radius of the part between the two ends of the adjustment plate to gradually decrease, and the guide structure guides the part between the two ends of the adjustment plate to approach the axis of the support tube.

[0012] Furthermore, the guide structure includes a sliding hole and a guide rod; the sliding hole is provided on the adjustment plate; the guide rod is provided on one side of the slide plate along the radial direction of the support tube; the guide rod is fixedly connected to the slide plate through a transverse connecting rod; the end of the guide rod away from the axis of the support tube is inserted into the sliding hole; the guide rod and the sliding hole are slidably matched.

Since the slide plate is slidably installed in the slide groove, the slide plate slides spirally along the slide groove, and the closer the slide plate is to the turntable, the more circles it rotates spirally around the axis of the support tube, so that the slide plate drives the pressure ball to gather toward the vertical ribs of the steel bar through the sliding seat, so that part of the pressure ball and the vertical ribs abut, so as to apply a rotational force to the steel bar through the vertical ribs, and the rotational forces applied by the two support tubes on the two ends of the steel bar are opposite, so as to rotate the vertical ribs of the steel bar. The limit position makes the two vertical ribs on the steel bar maintain vertical distribution; at the same time, when the turntable drives the adjusting plate close to the adjusting motor to rotate around the supporting tube along the spiral direction of the adjusting plate, the rotation of the movable end of the adjusting plate drives the spiral radius of the part between the two ends of the adjusting plate to gradually reduce, so that the part between the two ends of the adjusting plate approaches the axis of the supporting tube along the guide rod, so that the adjusting plate abuts against the side wall of the hemispherical end of the sliding seat, thereby driving the two sliding seats on the same sliding plate to overcome the spring force and approach each other, so that the two pressure balls on some sliding plates are clamped on both sides of the spiral ribs on the steel bar, increasing the rotation resistance of the steel bar, which helps to prevent the steel bar from rotating in the early stage of bending.

When the portion between the two ends of the adjustment plate approaches the axis of the support tube along the guide rod, the auxiliary plate presses against the surface of the steel bar, increasing the rotation resistance of the steel bar and reducing the possibility of the steel bar rotating.

[0014] Furthermore, a plurality of connection assemblies are provided, which are spaced apart on the adjustment plate; the connection assemblies include slots; the slots are spiral; the number of spiral turns of the slots is half a turn; the auxiliary plate is plugged into the slots, and the auxiliary plate and the adjustment plate are fixedly connected at the slots by bolts.

[0030] The guide structure includes a sliding hole 621 and a guide rod 622; the sliding hole 621 is arranged on the adjustment plate 620; the guide rod 622 is arranged on one side of the slide plate 520 along the radial direction of the support tube 310; the guide rod 622 is fixedly connected to the slide plate 520 through a transverse connecting rod; the end of the guide rod 622 away from the axis of the support tube 310 is inserted into the sliding hole 621; the guide rod 622 and the sliding hole 621 are slidably matched.

[0032] In combination with the above embodiments, the use principle and working process of the present invention are as follows: when in use, the first step is to pull out the pin, remove the support tube 310, insert the two ends of the steel bar 100 into the support tube 310, and make the two vertical ribs 110 on the steel bar 100 vertically distributed, and then insert the pin into the socket and rotate the pin to install it on the support column 300.

[0034] The third step is to start the power motor, drive the mounting plate 240 through the screw rod to drive the pressing block 250 to move downward and press against the steel bar 100 to bend the steel bar 100.

[0035] In the fourth step, after the steel bar 100 is bent at a certain angle, the adjusting motor 630 is rotated in the opposite direction at a certain angle to reduce the size of the limiting force on the steel bar 100, so that the steel bar 100 can slide relative to the supporting cylinder 310, thereby improving the detection effect. When the steel bar 100 is bent at a large angle, the elastic adjusting plate 620 and the auxiliary plate 640 provide a buffer in the extension direction of the steel bar 100 to adapt to the displacement of the steel bar 100 caused by the bending of the steel bar 100, thereby improving the detection effect.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
