Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, and in particular to a device for measuring the thickness of concrete slab floors. Background Technology

[0002] Concrete floor slabs are a widely used structural component in building construction, primarily composed of concrete and reinforced steel, possessing high load-bearing capacity and durability. The accuracy of the floor slab thickness is crucial for the structural stability and safety of a building. Ensuring that the thickness of the concrete floor slab meets design requirements during construction is a vital step in guaranteeing building quality. To accurately measure the thickness of the floor slab, specialized measuring devices are typically required. These devices not only improve the efficiency and accuracy of measurements but also avoid errors inherent in manual measurement, ensuring the safety and compliance of the structure.

[0003] Currently, most existing concrete slab thickness measuring devices adopt a fixed-length structural design, which cannot flexibly adjust the height of the equipment according to actual needs. In order to measure the thickness above the slab, it is usually necessary to build an additional platform or take other temporary measures, which not only increases the workload but also reduces the work efficiency. Therefore, a device for measuring the thickness of concrete slabs is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a device for measuring the thickness of concrete slab floors, aiming to improve the problem that the height of the equipment in the prior art is fixed and cannot be flexibly adjusted.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] One end of the spring is fixedly connected inside the fixing frame, and the other end of the spring is in contact with the toothed plate.

[0012] As a further description of the above technical solution:

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3This utility model provides an embodiment of a device for measuring the thickness of concrete slab floors, comprising a measuring frame 6, a motor 7 fixedly connected to the side wall of the measuring frame 6, a screw 8 fixedly connected to the output end of the motor 7, the screw 8 being rotatably connected inside the measuring frame 6, a limit post 9 fixedly connected inside the measuring frame 6, a measuring plate 10 threadedly connected to the side wall of the screw 8, a reference plate 11 fixedly connected to the side wall of the measuring frame 6, the measuring plate 10 being slidably connected to the side wall of the limit post 9, graduations provided on the side wall of the measuring frame 6, and an adjustment mechanism provided on the side wall of the measuring frame 6. The measuring frame 6 has a telescopic mechanism at its bottom. The telescopic mechanism includes a sleeve 1, a sliding rod 2 slidably connected inside the sleeve 1, a wing bolt 4 threaded inside the sliding rod 2, a pressing block 5 rotatably connected to the side wall of the wing bolt 4, the pressing block 5 fitting against the outside of the sleeve 1, a friction plate 3 on the side wall of the sleeve 1, the friction plate 3 being located on both sides of the sliding groove inside the sleeve 1, a handle 17 fixedly connected to the bottom of the sleeve 1, a rubber pad 18 fixedly connected to the side wall of the measuring frame 6, and a battery on the side wall of the measuring frame 6 for providing power to the motor 7.

[0031] When measuring a floor slab, the measuring frame 6 is placed on the side of the floor slab, with the reference plate 11 and measuring plate 10 positioned on opposite sides. The motor 7 is then started, causing the screw 8 to rotate. This rotation of the screw 8 moves the measuring plate 10 along the limiting post 9 until both the reference plate 11 and measuring plate 10 are in contact with the floor slab. At this point, since the reference plate 11 and measuring plate 10 are in contact with both sides of the floor slab, the thickness of the floor slab can be determined by observing the markings on the measuring plate 10 and recorded. When the plate is high, the wing bolt 4 can be twisted to move it outward. At this time, the pressure between the wing bolt 4 and the extrusion block 5 will change, causing the extrusion block 5 to separate from the friction plate 3. The overall height of the equipment can be changed by pulling the slide rod 2. After the height adjustment is completed, the operator twists the wing bolt 4 in the opposite direction to restore it to its original position and reapplies pressure to make the extrusion block 5 and the friction plate 3 in close contact. During the extrusion process, the extrusion block 5 will deform to ensure that the relative position between the sleeve 1 and the slide rod 2 is fixed, thereby completing the adjustment of the equipment height.

[0032] Reference Figures 1-4 The adjustment mechanism includes a fixed frame 12, the side wall of which is fixedly connected to the top of the slide rod 2. A toothed plate 13 is fixedly connected inside the fixed frame 12, and a toothed plate 14 is slidably connected inside the fixed frame 12. A connector 15 is fixedly connected to the side wall of the toothed plate 14, and the side wall of the connector 15 is slidably connected inside the toothed plate 13. The side wall of the connector 15 is fixedly connected to the side wall of the measuring frame 6. A spring 16 is provided inside the fixed frame 12. One end of the spring 16 is fixedly connected inside the fixed frame 12, and the other end of the spring 16 is in contact with the toothed plate 14. The toothed plate 14 is engaged with the toothed plate 13.

[0033] When the angle of the measuring frame 6 needs to be adjusted, the connector 15 on the measuring frame 6 can be moved backward by pressing the rubber pad 18. The backward movement of the connector 15 will cause the toothed plate 14 to slide inside the fixed frame 12. The engagement relationship between the toothed plate 14 and the toothed plate 13 changes during this process. The movement of the toothed plate 14 will compress and deform the spring 16. At this time, the operator can continue to adjust the angle of the measuring frame 6 by rotating it. The rotation of the measuring frame 6 causes the position of the toothed plate 14 relative to the toothed plate 13 to change, thereby making a fine adjustment to the angle of the measuring frame 6. After the adjustment is completed, the operator slowly releases the measuring frame 6. As the applied pressure gradually decreases, the spring 16 begins to gradually return to its original state. The gradual return of the spring 16 pushes the toothed plate 14 to re-engage with the toothed plate 13, and the angle of the measuring frame 6 will be firmly fixed, thereby ensuring the stability of the measuring frame 6 during the measurement process. In this way, not only can the angle of the measuring frame 6 be flexibly adjusted, but the stability and reliability of the adjustment process can also be ensured.

[0034] Working principle: When using this equipment, the measuring frame 6 is positioned on the side of the floor slab, with the reference plate 11 and measuring plate 10 on opposite sides. The motor 7 is then started, causing the screw 8 to rotate, which in turn moves the measuring plate 10, ensuring that the reference plate 11 and measuring plate 10 are simultaneously in contact with both sides of the floor slab. The measuring frame 6 is then removed from the floor slab. The thickness of the floor slab is determined by observing the scale corresponding to the measuring plate 10. When the equipment height needs to be adjusted to measure higher floor slabs, the wing bolt 4 can be twisted to move it outwards, separating the pressing block 5 from the friction plate 3. The height of the equipment can then be changed by pulling the sliding rod 2. After adjustment, the wing bolt is twisted in the opposite direction. 4. Press the extrusion block 5 again to make it fit tightly against the outside of the friction plate 3 and deform it, thereby fixing the position of the sleeve 1 and the slide rod 2, thus completing the adjustment of the equipment height. When it is necessary to adjust the angle of the measuring frame 6, the rubber pad 18 can be pressed to move the measuring frame 6 and the connecting head 15 backward. The movement of the connecting head 15 will further drive the toothed plate 14 to slide inside the fixed frame 12 and compress the spring 16 to deform it. Then, the angle can be changed by rotating the measuring frame 6. After the adjustment is completed, the measuring frame 6 can be slowly released. At this time, the spring 16 will gradually return to its original position due to the decrease in pressure, and finally the toothed plate 14 will re-engage with the toothed plate 13 to fix the angle of the measuring frame 6, so that the staff can carry out the measurement work.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
