[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The embodiment of the present application provides a device for detecting the position of steel bars in reinforced concrete construction. The device has a simple and portable structure, is convenient for locating the steel bars, and can also measure the thickness of the protective layers of different steel bars to correct the steel bars that do not meet the specifications before the template is installed.

[0030] like Figure 1-3 As shown, the embodiment of the present application provides a device for detecting the position of steel bars in reinforced concrete construction, which includes:

[0031] A caliper base 1, on which a guide slot 11 is formed, and a linear scale 12 is provided on the caliper base 1 and located on the outer edge of the guide slot 11;

[0032] A laser sight 2, which is mounted on the lower surface of the caliper base 1, and the emission port of the laser sight 2 is arranged downward for emitting laser;

[0033] The measuring unit 3 comprises:

[0034] - a probe rod 31, which is adapted to be received in the guide slot 11 and can move along the guide slot 11; at the same time, the front end of the probe rod 31 extends out of the caliper base 1 to abut against the steel bar to be detected;

[0035] - An identification member 32, which is arranged on the probe rod 31 and is opposite to the linear scale 12; the identification member 32 is used to indicate the distance moved by the probe rod 31 in the guide slot 11 to reflect the position of the steel bar to be detected.

[0036] In this embodiment, the above-mentioned device includes a caliper base 1, a laser sight 2 and a measuring part 3, wherein the measuring part 3 includes a probe rod 31 and an identification part 32, wherein the probe rod 31 includes a front end 31a of the probe rod and a rear end 31b of the probe rod, the front end 31a of the probe rod is used to abut against the steel bar to be detected, the probe rod 31 is in the guide groove 11, and the probe rod 31 passes through the caliper base 1, the front end 31a of the probe rod extends out of the caliper base 1, and the probe rod 31 can move forward or backward in a straight line along the guide groove 11, and drive the identification part 32 on the probe rod 31 to point to different scale values ​​on the linear scale 12, and the laser sight emits laser downward to form a laser point on the ground. When positioning the steel bar to be detected, first draw a reference line on the ground. The reference line is theoretically parallel to the steel bar to be detected, that is, assuming that the steel bar to be detected has not shifted, turn on the laser sight 2, keep the device in a horizontal state, the laser sight 2 emits a laser downward and displays a laser point on the ground, place the front end 31a of the probe rod against the position of the steel bar to be detected, and move the handheld caliper base 1 forward along the direction of the guide groove 11 until the laser point hits the reference line. At this time, the identification member 32 points to a certain scale value on the linear scale 12, which directly reflects the distance value from the front end 31a of the probe rod to the laser sight 2, and the distance value is also the distance from the position of the steel bar to be detected to the reference line, that is, the identification member 32 can be used to reflect the position of the steel bar to be detected.

[0037] In the actual reinforced concrete construction process, the steel bar protective layer is located at the outer edge of the structure, which can be determined by the distance from the outermost steel bar of the steel bar protective layer to the outer edge of the structure. A reference line is drawn at the outermost steel bar, that is, the reference line corresponds to the outer surface of the outermost steel bar. The front end 31a of the probe rod is placed against the outer edge of the structure. The above-mentioned positioning operation can also be used to measure the distance from the outermost steel bar of the steel bar protective layer to the outer edge of the structure, that is, the thickness of the steel bar protective layer can be measured.

[0038] Preferably, the laser sight 2 is vertically connected to the front end of the lower surface of the caliper base 1. In this embodiment, the laser sight 2 is vertically installed on the lower surface of the caliper base 1, so that the emission port of the laser sight 2 can be directly vertically downward, and the laser sight is arranged close to the front end of the caliper base 1, which can shorten the distance between the front end 31a of the probe rod and the laser sight 2 when it is at the farthest position, effectively reducing the redundant distance.

[0039] like Figure 1 , Figure 2As shown, as a preferred solution of an embodiment of the present application, the caliper base 1 has a limiting slot 13 opened inwardly on one side of the guide slot 11, and the measuring part 3 also includes a limiting protrusion 33 arranged on the side of the probe rod 31, and the limiting protrusion 33 extends into the limiting slot 13.

[0040] In this embodiment, the limiting protrusion 33 is embedded in the limiting groove 13, and the limiting protrusion 33 is connected to the side of the probe rod 31, which effectively prevents the probe rod 31 from being separated from the caliper base 1 during the movement.

[0041] Furthermore, the measuring part 3 is an integrated structure. In this embodiment, the probe rod 31, the identification member 32, and the limiting protrusion 33 in the measuring part 3 form an integrated structure to ensure the internal connection reliability of the measuring part 3, and more importantly, to ensure that the movement amounts of the probe rod 31, the identification member 32, and the limiting protrusion 33 are the same, thereby improving the measurement accuracy.

[0042] Furthermore, the device also includes:

[0043] The return spring 4 is in the limiting notch 13 ; the front end of the return spring 4 is connected to the limiting protrusion 33 , and the rear end is connected to the caliper base 1 ; meanwhile, the return spring 4 is in a compressed state.

[0044] In this embodiment, the return spring 4 is in the limiting groove 13. When the device for detecting the position of the steel bar is not used, the return spring 4 is in a compressed state, and can push the limiting protrusion 33 forward to the position closest to the laser sight 2; when in use, the return spring 4 continues to be compressed, and the limiting protrusion 33 moves in the limiting groove 13, and after use, the elastic force of the return spring 4 can be used to restore the limiting protrusion 33 to its original position.

[0045] Specifically, when the probe rod 31 extends out of the caliper base 1 to the farthest position, the scale value on the linear scale 12 pointed to by the identification member 32 is the same as the distance value from the farthest position to the laser sight 2 .

[0046] In this embodiment, the farthest position is the above-mentioned original position. When the scale value pointed to by the identification member 32 on the linear scale 12 is equal to the distance from the original position to the laser sight 2, the distance from the steel bar to be detected to the reference line can be quickly and directly determined.

[0047] Specifically, the scale on the linear scale 12 decreases from the front end to the rear end. In this embodiment, when the device is used to perform a steel bar positioning operation, the probe rod 31 abuts against the steel bar to be detected, and the caliper base 1 is pushed forward, the distance from the front end 31a of the probe rod to the laser sight 2 becomes smaller, and the identification member 32 moves backward, so when the scale on the linear scale 12 decreases from the front end to the rear end, the decreasing direction is the same.

[0048] When the probe rod 31 extends out of the caliper base 1 to the farthest position, the scale value on the linear scale 12 pointed by the identification member 32 is the same as the distance value from the farthest position to the laser sight 2; and the scale on the linear scale 12 decreases from the front end to the rear end. In this embodiment, the position of the steel bar to be detected from the reference line can be directly read according to the scale value on the linear scale 12 pointed by the identification member 32, and whether the steel bar to be detected has shifted can be quickly determined.

[0049] Specifically, the cross section of the probe rod 31 is rectangular. In the embodiment of the present application, when the cross section of the probe rod 31 is rectangular, the probe rod 31 is adapted to be accommodated in the guide slot 11 and can stably move forward or backward without deflection.

[0050] Specifically, the identification member 32 is a thin strip-shaped protrusion. In this embodiment, the protrusion is simple to set and has an obvious identification function.

[0051] Preferably, a universal bubble 14 is installed on the upper surface of the caliper base 1. In this embodiment, the universal bubble 14 is arranged on the upper surface of the caliper base 1, and whether the caliper base 1 is protected level can be determined according to the universal bubble 14, thereby improving the accuracy of measurement.
