Description

Technical Field

[0001] The utility model relates to the technical field of measuring reinforcing bar holes, and more specifically to a detection device for reinforcing bar holes in a pile-sheet wall. Background Art

[0002] In the field of construction engineering, especially in important structures such as high-rise buildings, bridges, and tunnels, pile-sheet walls are an important foundation component, and their stability and safety are of vital importance. Pile-sheet walls are usually made of reinforced concrete, and their bearing capacity and pull-out resistance are enhanced by implanting steel bars. However, due to various factors during the construction process, such as insufficient drilling depth, insufficient filling of adhesives, or poor curing, the quality of the rebar holes may not meet the design requirements, thus affecting the stability and safety of the entire structure. Therefore, it is particularly important to accurately detect the rebar holes in pile-sheet walls.

[0003] Chinese utility model patent CN217637140U discloses a measuring tool for measuring the depth of rebar holes, which relates to the field of rebar measurement technology, including a ruler, wherein the measuring mechanism is movably connected inside the ruler, wherein the measuring mechanism includes a measuring device and a dust cleaning device, wherein the left side of the measuring device is fixedly connected to the left side of the inner wall of the ruler, and the outer wall of the measuring device is fixedly connected to the dust cleaning device, a through hole is provided on the right surface of the ruler, and a screw cover is provided on the left side of the upper surface of the ruler. The utility model solves the problem that the traditional method has cumbersome detection steps, which will take up too much time of the detection personnel and affect the construction progress by setting a blower to allow the brick dust to enter the collection box and clean the brick dust in the hole. There is no need to first clean the brick dust in the rebar hole with an instrument and then measure the depth of the rebar hole. The cumbersome steps of inserting the rebar hole twice save human resources.

[0004] The above technical solution has the following problems: it is found in actual use that the measuring tool cannot limit the measuring rod. After the depth measurement of a rebar hole is completed, the measuring rod will be retracted into the ruler under the action of the elastic force of the spring, and the staff will need to push and pull the measuring rod again for measurement, which makes the detection of the rebar holes more troublesome. Moreover, once the staff does not hold the slider firmly when measuring the depth of the rebar hole, the measurement data will be inaccurate, affecting the subsequent construction.

[0022] Figure 1-Figure 4 This is the best embodiment of the utility model, and the following is combined with the accompanying drawings Figure 1-Figure 4 The utility model is further described.

[0023] A detection device for reinforcement holes in a pile-sheet wall comprises a ruler body 1, a baffle plate 2, a measuring rod 3, an adjustment assembly 4 and a limit assembly 5. The baffle plate 2 is fixedly mounted on the side of the ruler body 1, the measuring rod 3 and the adjustment assembly 4 are arranged inside the ruler body 1, the adjustment assembly 4 is connected to the measuring rod 3, and drives the measuring rod 3 to move in a direction close to or away from the baffle plate 2, and the limit assembly 5 is arranged inside the baffle plate 2.

[0024] Specifically, the adjustment component 4 includes a bearing seat 401, the bearing seat 401 is fixedly installed inside the ruler body 1, the bearing seat 401 is rotatably connected to the inside of the bearing seat 401, the surface of the screw rod 402 is threadedly connected to a movable plate 403, the side of the movable plate 403 is fixedly installed on the measuring rod 3, the side of the screw rod 402 away from the bearing seat 401 is fixedly connected to a bevel gear 1 404, the surface of the bevel gear 1 404 is meshed with a bevel gear 2 405, and the top of the bevel gear 2 405 is fixedly connected to a knob 406.

[0025] In this embodiment, the bevel gear 2 405 can be driven to rotate by rotating the knob 406. Under the meshing transmission of the bevel gears, the bevel gear 1 404 can drive the screw rod 402 to rotate. Under the interaction between the external thread of the screw rod 402 and the internal thread of the movable plate 403, the movable plate 403 will move left and right, thereby driving the measuring rod 3 to move inward and outward together.

[0026] Specifically, a guide rod 407 is fixedly installed inside the ruler body 1, and the movable plate 403 is slidably connected to the guide rod 407.

[0027] In this embodiment, the movable plate 403 can slide on the surface of the guide rod 407 while moving, playing a guiding and limiting role.

[0028] Specifically, an indicator plate 6 is fixedly installed on the side of the movable plate 403 , and an observation window 7 is fixedly installed on the side of the ruler body 1 . The observation window 7 is made of transparent tempered glass, and scale lines are arranged on the outer side of the observation window 7 .

[0029] In this embodiment, the staff can understand the depth of the reinforcing bar hole through the scales on the indicator plate 6 and the outer side of the observation window 7.

[0030] Specifically, the limiting assembly 5 includes a spring 501, a spring 501 and a limiting rod 504 are fixedly installed inside the baffle 2, a lifting plate 502 is fixedly connected to the side of the spring 501, a shift plate 503 is fixedly installed on the outer side of the lifting plate 502, the lifting plate 502 is slidably connected to the limiting rod 504, and a clamping plate 505 is fixedly connected to the side of the lifting plate 502 away from the spring 501.

[0031] In this embodiment, the lifting plate 502 can be driven to move up and down by pushing and pulling the dial plate 503. When the dial plate 503 is not affected by external force, it will move away from the spring 501 under the elastic force of the spring 501, so that the measuring rod 3 can be fixed between the two clamping plates 505.

[0032] Specifically, there are two clamping plates 505 , which are symmetrically distributed up and down with the middle line of the baffle 2 as the symmetry axis. The shape of the clamping plates 505 is arc-shaped, and a rubber pad 506 is bonded to the side of the clamping plates 505 .

[0033] In this embodiment, the two sets of clamping plates 505 are used in combination to better limit the position of the measuring rod 3, and the rubber pad 506 bonded to the side of the clamping plate 505 can increase the friction force, thereby improving the fixing effect.

[0034] Specifically, a detector 8 is fixedly installed on the outside of the ruler body 1, and a display screen 9 and a control button 10 are arranged on the outside of the detector 8. A laser distance sensor 11 is arranged inside the ruler body 1, and the laser distance sensor 11 is electrically connected to the detector 8, the display screen 9 and the control button 10. A PLC controller and a calculator are arranged inside the detector 8, and the PLC controller is connected to the calculator, the laser distance sensor 11, the display screen 9 and the battery or power cord. The detector 8 can also use the existing KS-3T rebar pulling instrument.

[0035] In this embodiment, the distance between the laser ranging sensor 11 and the movable plate 403 can be measured by the laser ranging sensor 11, so as to infer the length of the extended measuring rod 3. The staff can quickly understand the depth data of the rebar hole directly on the detector 8, which greatly improves the detection efficiency.

[0036] The working principle and use process of the utility model are as follows: when it is necessary to measure the depth of the anchor hole, the baffle plate 2 is placed on the side of the pile wall, and the two dial plates 503 are first pulled outward to retract the two clamping plates 505 into the baffle plate 2, and then the knob 406 is turned to drive the bevel gear 2 405 to rotate. Under the meshing transmission of the bevel gears, the bevel gear 1 404 can drive the screw rod 402 to rotate. Under the interaction between the external thread of the screw rod 402 and the internal thread of the movable plate 403, the movable plate 403 will move left and right, thereby driving the measuring rod 3 to move inside. When the measuring rod 3 cannot move, it means that it is against the bottom of the rebar hole. At this time, the staff can understand the depth of the rebar hole through the position of the indicator plate 6 and the scale on the outside of the observation window 7, and can also quickly understand the depth data of the rebar hole directly on the detector 8, which greatly improves the detection efficiency. After the depth of a rebar hole is measured, there is no need to readjust the length of the measuring rod 3, and another rebar hole can be inserted for depth measurement, which reduces the steps of repeated adjustment, facilitates the measurement of multiple rebar holes, and greatly improves the detection efficiency.
