Description

Technical Field

[0001] This utility model relates to the field of building acceptance equipment technology, and in particular to a floor thickness detection device. Background Technology

[0002] In the field of building construction, accurately measuring the concrete floor thickness to ensure it meets design requirements is a crucial quality control step before the acceptance of the main concrete structure and the handover of new buildings. Floor thickness directly affects the structural load-bearing capacity, sound insulation performance, and durability; therefore, its accurate measurement is a key step in ensuring building safety and functionality.

[0003] Currently, a common method involves one person holding a template below the floor to hold the hole, while another person above the floor inserts a short steel bar into the hole until the bottom of the bar touches the template surface below. A mark is then made on the upper surface of the floor, close to the steel bar, and the bar is removed. The distance from the marked line to the bottom of the steel bar is measured using a tape measure to determine the floor thickness. However, this method has many drawbacks. On the one hand, it requires close cooperation between two people, adding coordination difficulty and inconvenience to the floor measurement process. On the other hand, the measurement efficiency is low. In actual operation, it is essential to ensure that the measurement process is absolutely perpendicular to the ground; any tilting can easily lead to measurement errors, affecting the accuracy of the test results. Utility Model Content

[0004] The main purpose of this invention is to provide a floor thickness detection device, which aims to improve measurement accuracy and efficiency.

[0005] To achieve the above objectives, the floor thickness detection device proposed in this utility model includes:

[0006] A first rod body, with a connecting plate at one end of the first rod body, and four flip plates rotatably connected to the connecting plate. The four flip plates are spaced apart along the circumference of the connecting plate, and each flip plate has a first measuring surface.

[0007] The second rod is partially sleeved inside the first rod. The second rod has a clamping plate at one end near the connecting plate. The clamping plate has a first clamping surface, which abuts against the flip plate. When the clamping plate moves toward the connecting plate, the clamping plate pushes the flip plate to flip outward.

[0008] The connecting plate is provided with a second clamping surface near the clamping plate. The first clamping surface and the second clamping surface are parallel and together clamp the flip plate so that the first measuring surface is perpendicular to the axis of the first rod.

[0009] A calibration assembly is movably connected to the first rod and coaxially arranged. Multiple calibration plates extend outward from the periphery of the calibration assembly. Each calibration plate has a second measuring surface, which is perpendicular to the axis of the first rod.

[0010] In one embodiment, the second clamping surface of the connecting plate is provided with a connecting boss, and the flip plate is rotatably connected to the connecting boss;

[0011] The connecting boss is provided with a limiting part to limit the angle at which the flip plate flips inward;

[0012] When the flip plate is flipped inward and in a closed state, the clamping disk abuts against the inner wall of the flip plate.

[0013] In one embodiment, the inner sidewall of the flipping plate has an inclined surface near the clamping plate;

[0014] When the flip plate is flipped inward and in a closed state, the clamping plate abuts against the inclined surface, and the angle between the first clamping surface and the inclined surface is less than 90°.

[0015] In one embodiment, the periphery of the first clamping surface is chamfered to smoothly abut against the flip plate.

[0016] In one embodiment, the calibration assembly includes a connecting sleeve that is fitted onto the outer wall of the first rod, and the calibration plate is integrally connected to the periphery of the connecting sleeve.

[0017] When the flip plate is flipped outwards and in the measurement state, the first measurement surface and the second measurement surface are parallel.

[0018] In one embodiment, the outer wall of the first rod is provided with scale lines, which are adapted to the side of the connecting sleeve away from the connecting disc.

[0019] In one embodiment, the connecting sleeve is threaded to the outer wall of the first rod.

[0020] In one embodiment, the calibration assembly further includes a locking sleeve that abuts against the connecting sleeve, the locking sleeve being threadedly connected to the outer wall of the first rod, and the connecting sleeve being slidably connected to the outer wall of the first rod.

[0021] In one embodiment, the inner wall of the first rod is threaded, which is adapted to the external thread of the second rod. When the clamping disc pushes the flipping plate to flip outward in the measurement state, the second rod and the first rod are threadedly connected.

[0022] In one embodiment, a turntable is fixedly connected to the end of the second rod away from the clamping disk.

[0023] The technical solution of this utility model, through the first rod and the second rod, eliminates the need for assistance from others below the floor. When the flip plate flips inward to close, the operator inserts the first rod and the second rod into the hole opened in the floor, passes them through, and then pulls the second rod. The clamping plate drives the flip plate to flip outward, and the first clamping surface and the second clamping surface together clamp the flip plate, ensuring the stability of the unfolded shape. The four unfolded flip plates can prevent the flip plates from tilting. The calibration plate is located above the floor. The parallel calibration plate and the flip plates prevent the measurement angle from tilting, ensuring the measurement progress. The floor thickness can be obtained through the relative displacement between the calibration component and the first rod. Attached Figure Description

[0036] In the field of building construction, accurately measuring the concrete floor thickness to ensure it meets design requirements is a crucial quality control step before the acceptance of the main concrete structure and the handover of new buildings. Floor thickness directly affects the structural load-bearing capacity, sound insulation performance, and durability; therefore, its accurate measurement is a key step in ensuring building safety and functionality.

[0037] Currently, a common method involves one person holding a template below the floor to hold the hole, while another person above the floor inserts a short steel bar into the hole until the bottom of the bar touches the template surface below. A mark is then made on the upper surface of the floor, close to the steel bar, and the bar is removed. The distance from the marked line to the bottom of the steel bar is measured using a tape measure to determine the floor thickness. However, this method has many drawbacks. On the one hand, it requires close cooperation between two people, adding coordination difficulty and inconvenience to the floor measurement process. On the other hand, the measurement efficiency is low. In actual operation, it is essential to ensure that the measurement process is absolutely perpendicular to the ground; any tilting can easily lead to measurement errors, affecting the accuracy of the test results.

[0038] This utility model proposes a floor thickness detection device.

[0039] Please see Figures 1 to 5 In one embodiment of this utility model, the floor thickness detection device includes:

[0040] A first rod body 1, with a connecting plate 11 at one end, and four flip plates 12 rotatably connected to the connecting plate 11. The four flip plates 12 are spaced apart around the connecting plate 11, and each flip plate 12 has a first measuring surface 121.

[0041] The second rod 2 is partially sleeved inside the first rod 1. The second rod 2 has a clamping plate 21 at one end near the connecting plate 11. The clamping plate 21 has a first clamping surface 211. The first clamping surface 211 abuts against the flip plate 12. When the clamping plate 21 moves toward the connecting plate 11, the clamping plate 21 pushes the flip plate 12 to flip outward.

[0042] The connecting plate 11 is provided with a second clamping surface 112 near the clamping plate 21. The first clamping surface 211 and the second clamping surface 112 are parallel and together clamp the flip plate 12 so that the first measuring surface 121 is perpendicular to the axis of the first rod 1.

[0043] A calibration assembly is movably connected to the first rod 1 and coaxially arranged. Multiple calibration plates 32 extend outward from the periphery of the calibration assembly. Each calibration plate 32 is provided with a second measuring surface 321, which is perpendicular to the axis of the first rod 1.

[0044] For ease of understanding, the direction of the first rod 1 closest to the connecting plate 11 is defined as downward, and the side away from the connecting plate 11 is defined as upward. In use, the first rod 1 is inserted downward into the hole opened in the floor.

[0045] like Figure 1 and Figure 3As shown, the flip plate 12 includes an inward flipped closed state and an outward flipped measuring state. When the clamping plate 21 is not in contact, the flip plate 12 will rotate downward. At this time, the horizontal area occupied by the flip plate 12 is small, which can smoothly pass through the measuring holes opened on the floor. After the measurement is completed, it can be directly retracted.

[0046] Furthermore, when the second rod 2 is pulled upwards, the clamping disc 21 abuts against the inner side of the flipping plate 12, causing the flipping plate 12 to flip outwards. When it flips to be parallel to and abuts against the second clamping surface 112, the first clamping surface 211 and the second clamping surface 112 together adhere to and clamp the flipping plate 12 to ensure that the three are parallel. At this time, the first measuring surface 121 is perpendicular to the axis of the first rod 1, and the second measuring surface 321 is also perpendicular to the axis of the first rod 1. Therefore, the first measuring surface 121 and the second measuring surface 321 are parallel. Figure 2 As shown, if the first measuring surface 121 located below the floor is tilted relative to the floor ground, the first measuring surface 121 above the floor will also be tilted relative to the ground, making it easier for the operator to observe; secondly, by continuously bringing the two closer together and fitting them against the opposite sides of the floor, the verticality of the first rod 1 to the floor ground can be ensured, thus improving the measurement progress.

[0047] like Figure 2 As shown, the length of the first rod 1 is fixed, and when the flip plate 12 is flipped outward and in the measurement state, the relative position of the first measuring surface 121 and the first rod 1 is fixed. Therefore, by determining the relative position of the calibration component on the first rod 1, the thickness of the floor can be obtained, which can be determined by measuring the difference in the relative distance between the two.

[0048] The technical solution of this utility model, through the first rod 1 and the second rod 2, eliminates the need for assistance from others below the floor. When the flip plate 12 flips inward to close, the operator inserts the first rod 1 and the second rod 2 into the hole opened in the floor, passes them through, and then pulls the second rod 2. The clamping plate 21 drives the flip plate 12 to flip outward, and the first clamping surface 211 and the second clamping surface 112 jointly clamp the flip plate 12, ensuring the stability of the unfolded shape. The four flip plates 12 after unfolding can prevent the flip plates 12 from tilting. The calibration plate 32 is located above the floor. The parallel calibration plate 32 and the flip plates 12 prevent the tilt of the measurement angle, ensure the measurement progress, and the floor thickness can be obtained through the relative displacement between the calibration component and the first rod 1.

[0049] It should be noted that two adjacent connecting disks 11 are at a 90° angle, and there are four connecting disks 11.

[0050] like Figure 4 As shown, the second clamping surface 112 of the connecting plate 11 is provided with a connecting boss 111, and the flip plate 12 is rotatably connected to the connecting boss 111;

[0051] The connecting boss 111 is provided with a limiting part 1111 to limit the angle at which the flip plate 12 flips inward;

[0052] When the flip plate 12 is flipped inward and in a closed state, the clamping disk 21 abuts against the inner sidewall of the flip plate 12.

[0053] It is understood that the limiting part 1111 restricts the inward rotation angle of the flip plate 12 to avoid the situation where the first measuring surface 121 of the flip plate 12 is perpendicular to the first clamping surface 211 and the flip plate 12 cannot be smoothly pushed to rotate.

[0054] In some embodiments, the flip plate 12 is square.

[0055] Optionally, the inner sidewall of the flip plate 12 is provided with an inclined surface 122 on the side near the clamping plate 21;

[0056] When the flip plate 12 is flipped inward and in a closed state, the clamping plate 21 abuts against the inclined surface 122, and the angle between the first clamping surface 211 and the inclined surface 122 is less than 90°.

[0057] It is understandable that the inclined surface 122 guides the clamping disk 21 to a more continuous path from the closed position to the unfolded position, avoiding jamming caused by rigid collisions and improving the operating feel.

[0058] Optionally, the periphery of the first clamping surface 211 is chamfered to smoothly abut against the flip plate 12.

[0059] It is understandable that by chamfering the periphery of the first clamping surface 211, the line contact with the flip plate 12 is optimized into a gradient surface contact, improving the feel and preventing the sharp edge of the clamping plate 21 from scratching the surface of the flip plate 12 during repeated movements.

[0060] like Figure 2 and Figure 5 As shown, the calibration assembly includes a connecting sleeve 31, which is sleeved on the outer wall of the first rod body 1, and the calibration plate 32 is integrally connected to the periphery of the connecting sleeve 31.

[0061] When the flip plate 12 is flipped outwards and in the measurement state, the first measurement surface 121 and the second measurement surface 321 are parallel.

[0062] It is understood that the multiple calibration plates 32 are slidably connected to the first rod 1 through the connecting sleeve 31, and it is ensured that the second measuring surface 321 is always perpendicular to the axis of the first rod 1 during the movement, thus ensuring the accuracy of the measurement.

[0063] In some embodiments, there are four calibration plates 32, which are spaced apart around the connecting sleeve 31. Similar to the flip plate 12, the four spaced calibration plates 32 ensure that the second measuring surface 321 fits against the upper surface of the floor, thus preventing tilting.

[0064] In one embodiment, the outer wall of the first rod 1 is provided with scale lines, which are adapted to the side of the connecting sleeve 31 away from the connecting disk 11.

[0065] Understandably, during measurement, it is only necessary to observe the scale value aligned with the end face of the connecting sleeve 31, which is the actual measured value of the floor slab thickness.

[0066] It should be noted that the scale values ​​are calculated accordingly, rather than the distance between the scale line and the end of the first rod 1, which can be obtained directly without calculation.

[0067] In another embodiment, the connecting sleeve 31 is threaded to the outer wall of the first rod body 1.

[0068] It is understood that by rotating the connecting sleeve 31, the calibration plate 32 is made to move closer to the flip plate 12, and then it will automatically correct itself to fit with the floor surface. The first rod 1 and the connecting sleeve 31 will not easily shift, and the operator does not need to hold it. Measurement and calculation can be performed when the calibration plate 32 and the flip plate 12 are in contact with the upper and lower surfaces of the floor.

[0069] It should be noted that because the outer wall of the first rod 1 is threaded, the scale cannot be easily read, but at this time it is possible to release the hand and perform measurement and calculation using a measuring tool.

[0070] In another embodiment, the calibration assembly further includes a locking sleeve 33, which abuts against the connecting sleeve 31, and the locking sleeve 33 is threadedly connected to the outer wall of the first rod body 1, while the connecting sleeve 31 is slidably connected to the outer wall of the first rod body 1.

[0071] like Figure 2 As shown, when the calibration plate 32 approaches the upper surface of the floor, there is a large friction between the two, making it difficult to rotate the connecting sleeve 31. However, the locking sleeve 33 can effectively push the connecting sleeve 31 down for measurement, so the connecting sleeve 31 does not need to rotate.

[0072] Optionally, the inner wall of the first rod 1 is provided with threads that are adapted to the external threads of the second rod 2. When the clamping disc 21 pushes the flipping plate 12 to flip outward in the measurement state, the second rod 2 and the first rod 1 are threadedly connected.

[0073] It is understood that when the clamping plate 21 pushes the flip plate 12 to the measurement position, the internal thread of the first rod 1 engages and locks with the external thread of the second rod 2. At this time, the first rod 1 and the second rod 2 are relatively fixed, and the flip plate 12 can be in the measurement state without the operator applying external force.

[0074] Furthermore, by connecting the connecting sleeve 31 or the locking sleeve 33 to the first rod body 1 with a threaded connection, the floor can be relatively fixed. At this time, the operator does not need to apply external force to ensure that the equipment is in the measuring state.

[0075] In some embodiments, the second rod 2 needs to move a certain distance to enable the flip plate 12 to flip or close, while the first rod 1 is only partially threaded, and this part of the thread only engages when the clamping plate 21 pushes the flip plate 12 to flip outward and approach the measurement state. In the initial stage of the unfolding of the flip plate 12, i.e. the non-threaded segment of the stroke, the second rod 2 can slide without resistance.

[0076] Optionally, a turntable 22 is fixedly connected to one end of the second rod 2 away from the clamping disk 21.

[0077] It is understandable that the turntable 22 facilitates the rotation of the second rod 2.

[0078] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
