Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a building floor thickness detection device. Background Art

[0002] In the field of construction engineering, floor thickness is a key quality indicator, which is directly related to the structural safety and stability of the building.

[0003] Traditional floor thickness detection methods often rely on relatively simple tools and manual operations, which not only have low detection efficiency but also have difficulty in ensuring accuracy. For example, using a simple steel ruler for direct measurement is difficult to ensure the accuracy of the measurement position, and the measurement process is easily interfered by human factors, such as measurement angle deviation, non-vertical placement of the steel ruler, etc., which leads to large errors in the measurement results. For this reason, we propose a building floor thickness detection device. Utility Model Content

[0004] The utility model is to solve the problem that the traditional floor thickness detection method in the prior art often relies on relatively simple tools and manual operations, which not only has low detection efficiency, but also has difficulty in ensuring accuracy. For example, it is difficult to ensure the accuracy of the measurement position when using a simple steel ruler for direct measurement, and it is easily interfered by human factors during the measurement process, such as measurement angle deviation, non-vertical placement of the steel ruler, etc., which leads to large errors in the measurement results. At the same time, in the complex environment of the construction site, the lack of effective fixing and leveling devices makes it difficult for the detection equipment to be stably placed on the floor for accurate measurement, further affecting the reliability of the detection data. The proposed building floor thickness detection equipment meets the needs of modern construction project quality inspection, ensures the overall quality and safety of the building, reduces potential safety hazards and quality problems caused by floor thickness problems, improves the standardization and standardization level of construction, and reduces the cost of later maintenance and rectification.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for detecting the thickness of a building floor slab comprises a positioning plate, the center of the positioning plate being threadedly connected with an extension rod, a guide hole being arranged on the upper side of the positioning plate, a measuring device for measuring the measuring hole of the building floor slab being inserted into the guide hole, a limiting assembly being arranged on the bottom side of the extension rod, the limiting assembly being used in conjunction with the positioning plate to fix the entire device for detecting the thickness of the building floor slab, and a fixing assembly being arranged on the lower side of the positioning plate.

[0007] Preferably, the limiting assembly includes a groove, which is arranged on the lower side of the extension rod, and the lower side of the groove is threadedly connected to a bottom cover, a transmission rod is rotatably connected inside the extension rod, a bevel gear 1 is arranged at the bottom end of the transmission rod, and bevel gear 2 is meshedly connected to the left and right sides of the bevel gear 1, a threaded rod is sleeved on one side of the bevel gear 2, one end of the threaded rod is threadedly connected to a moving block, and a rotating disk is arranged at the top of the transmission rod.

[0008] Preferably, plug-in slots are provided on both sides of the bottom cover, a plug-in plate is provided in the plug-in slot, a guide block is provided on one side of the plug-in plate, one side of the guide block is slidably connected to one side of the moving block, and a fixed threaded pin is provided on the lower side of the bottom cover, one end of one side of the fixed threaded pin is connected to one side of the plug-in plate.

[0009] Preferably, the fixing assembly comprises a guide rod, the guide rod is arranged in the inner middle part of the guide hole, a fixing strip is sleeved on the outer side of the guide rod, a spring is arranged on one side of the fixing strip, and the spring is sleeved on the outer side of the guide rod.

[0010] Preferably, a level ruler is provided on the upper side of the positioning plate, an adjusting rod is provided on the upper side of the positioning plate, a leveling frame is threadedly connected to the outer side of the adjusting rod, and one side of the leveling frame passes through one side of the positioning plate.

[0011] Preferably, a rubber anti-slip sleeve is sleeved on the outer top of the extension rod.

[0012] In summary, the beneficial effects of the utility model are as follows:

[0013] Accurate measurement: The measuring hole of the building floor is measured by the measuring instrument. With the help of positioning plates, extension rods and other components, the thickness of the floor can be accurately determined, providing reliable data support for construction quality inspection and effectively ensuring the quality of the project.

[0014] Stable fixation: In the limit assembly, the various components cooperate with each other. For example, the bevel gear transmission drives the threaded rod and the moving block to move, and works together with the bottom cover to enable the equipment to be stably fixed to the floor during measurement, avoiding shaking that affects the measurement results and ensuring measurement accuracy. At the same time, the design of the bottom cover facilitates installation and disassembly, thereby improving work efficiency.

[0015] Convenient leveling: The combination of the spirit level, adjustment rod and leveling frame on the positioning plate makes it easy for the operator to quickly level the positioning plate, creating good conditions for subsequent precise measurements, ensuring the standardization and accuracy of the measurement process, and reducing measurement errors caused by uneven placement.

[0016] Safe operation: The rubber anti-slip sleeve on the outside of the extension rod can increase the friction, preventing the operator from slipping during operation and causing the equipment to fall and be damaged or causing safety accidents, thereby ensuring the personal safety of the operator and the integrity of the equipment, so that the detection work can proceed smoothly.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figure 1-Figure 5 As shown, a building floor thickness detection device, pick up the positioning plate 1, align the extension rod 2 with the threaded hole in the center of the positioning plate 1, and slowly rotate the extension rod 2 by hand to make it smoothly penetrate and threaded on the positioning plate 1. In this process, pay attention to the resistance of rotation to ensure that the threaded connection is tight and smooth without jamming or skewing. If you encounter a part with greater resistance, you can appropriately add a small amount of lubricating oil to assist installation, but avoid excessive contamination of lubricating oil that affects subsequent use.

[0025] Next, carefully insert the measuring device 4 into the guide hole 3 on the upper side of the positioning plate 1. Before insertion, check whether the inside of the guide hole 3 is smooth. If there are burrs or protrusions, use fine sandpaper to gently polish it to ensure that the measuring device 4 can slide freely in the guide hole 3 and that no additional friction is generated during the sliding process to affect the measurement accuracy. After insertion, gently push and pull the measuring device 4 to verify its flexibility.

[0026] Find the groove 5 on the lower side of the extension rod 2, and thread the bottom cover 6 to the lower side of the groove 5. When tightening the bottom cover 6, make sure that the thread is fully engaged and the bottom cover 6 is firmly installed and will not loosen or fall off during subsequent use.

[0027] The transmission rod 7 is connected to the extension rod 2 by rotation through a suitable bearing or sleeve structure to ensure that the transmission rod 7 can rotate flexibly. During the installation process, special attention should be paid to ensure that the bevel gear 1 8 is accurately meshed with the bevel gear 2 9 on both sides. The meshing clearance should be moderate, neither too large to cause inaccurate transmission nor too small to cause jamming. The transmission rod 7 can be gently rotated manually to observe the meshing of the bevel gears for fine adjustment.

[0028] One end of the threaded rod 10 is sleeved with the bevel gear 2 9 to ensure that the connection is tight and can rotate synchronously with the bevel gear 2 9. The other end is threadedly connected with the moving block 11. At this time, you can manually turn the transmission rod 7 a little to observe whether the moving block 11 can move smoothly left and right along the threaded rod 10. If there is a jam, check whether the threaded connection is correct or whether there is any foreign object blocking it.

[0029] Insert the plug-in board 12 into the plug-in slots on both sides of the bottom cover 6, so that the guide block 13 is tightly slidably connected to one side of the moving block 11. At the same time, check whether the fixed threaded pin 14 firmly connects the plug-in board 12 to the bottom cover 6 to ensure that the plug-in board 12 will not be separated from the bottom cover 6 during the use of the device, and ensure the structural stability of the entire limit assembly.

[0030] Install the level ruler 19 on the upper side of the positioning plate 1. The level ruler 19 should fit the surface of the positioning plate 1 and be firmly installed to ensure the accuracy of its measurement. Then, fix the adjustment rod 20 at the specified position of the positioning plate 1, and screw the leveling frame 21 to the outside of the adjustment rod 20. Adjust the position of the leveling frame 21 so that one side of it can penetrate the positioning plate 1 and can be flexibly moved left and right on the adjustment rod 20, so as to be used to adjust the levelness of the equipment later.

[0031] Finally, select a rubber anti-slip cover 22 of appropriate size and put it on the outer top of the extension rod 2. Make sure that the rubber anti-slip cover 22 is tight and will not slip off easily, so as to provide a good anti-slip effect for the operator when holding the extension rod 2, and prevent the equipment from falling or operating errors due to hand slippage.

[0032] After assembly, conduct a comprehensive inspection of the equipment. Turn the transmission rod 7 again to see if the moving block 11 moves smoothly and whether there is any abnormal noise or jamming. Push and pull the measuring device 4 to check if it can still slide flexibly in the guide hole 3. Check if the connections between the bottom cover 6, the adjustment rod 20, the leveling frame 21 and other components are firm.

[0033] Use a standard sample with known thickness to perform simulated measurement and debugging. Place the device on the standard sample, first observe the level ruler 19, and turn the adjustment rod 20 to adjust the position of the leveling frame 21 to make the device reach a horizontal state. At this time, the bubble should be at the center of the level ruler 19. Then, turn the rotating disk 15 at the top of the extension rod 2 to drive the limit assembly to work, and observe whether the moving block 11 can effectively fix the device and will not cause damage to the standard sample. Finally, insert the measuring instrument 4 into the guide hole 3 for measurement, and compare the measurement result with the actual thickness of the standard sample. If there is an error, calibrate the measuring instrument 4 to ensure that the measurement accuracy is within the allowable range.

[0034] Carry the debugged equipment to the construction site. After arriving at the area where the floor thickness needs to be tested, first clean up the debris and dust on the surface of the floor to ensure that the area where the equipment is placed is clean and flat to prevent debris from affecting the placement of the equipment and the measurement accuracy.

[0035] According to the approximate height of the floor, preliminarily estimate the length that the extension rod 2 needs to extend, and then rotate the extension rod 2 by hand to make the positioning plate 1 roughly at an appropriate height, generally slightly higher than the floor surface, to facilitate subsequent fine adjustments.

[0036] Gently place the equipment on the floor and judge the levelness of the equipment by observing the level ruler 19 on the positioning plate 1. If the level ruler 19 shows that the equipment is tilted, the operator slowly turns the adjustment rod 20 to move the leveling frame 21 left and right on the adjustment rod 20, and makes fine adjustments according to the direction and degree of tilt until the bubble of the level ruler 19 is centered, indicating that the equipment has been adjusted to a horizontal state.

[0037] After the equipment is leveled, the operator holds the extension rod 2 with one hand and rotates the rotating disk 15 at the top of the extension rod 2 with the other hand. The rotating disk 15 drives the transmission rod 7 to rotate, and then the bevel gear 1 8 drives the bevel gear 2 9 to rotate, and the threaded rod 10 sleeved on the bevel gear 2 9 also rotates accordingly. Under the action of the thread, the moving block 11 extends outward from the inside of the extension rod 2 until the moving block 11 tightly contacts the inner wall of the hole in the floor or other structures that can be fixed, such as floor steel bars, etc., to firmly fix the equipment on the floor to prevent the equipment from being displaced during the measurement process and affecting the measurement results. At the same time, because the plug-in plates 12 on both sides of the bottom cover 6 are slidably connected to the moving block 11 through the guide block 13, and the fixed threaded pin 14 ensures the integrity of the structure, the entire limit assembly is more stable and reliable during the fixing process.

[0038] After the equipment is fixed, the operator gently presses the measuring device 4 to move it downward along the guide hole 3 until the measuring end of the measuring device 4 contacts the lower surface of the floor. At this time, the value displayed on the measuring device 4 is read, which is the floor thickness at the current measuring point. During the measurement process, the guide hole 3 provides a vertical guide for the measuring device 4 to ensure the accuracy of the measurement path, and cooperates with the positioning plate 1, extension rod 2 and other components to effectively ensure the accuracy of the measurement.

[0039] If it is necessary to measure the thickness of different positions of the floor slab, after completing one measurement, slowly lift the measuring device 4, return it to the initial position, and fix it in the guide hole 3. Then move the device to a new measuring point, repeat the above leveling, fixing, and measuring steps, and measure and record the data of each point in turn. When selecting the measuring point, a reasonable measurement layout can be adopted according to factors such as the size and structural characteristics of the floor slab. For example, for large-area floor slabs, a layout such as a nine-square grid or a rice grid can be adopted to ensure that the thickness of the floor slab is fully and accurately reflected.

[0040] After completing all the measurement tasks, the operator first reverses the rotating disk 15 at the top of the extension rod 2 to drive the transmission rod 7 to reverse, so that the moving block 11 is retracted into the extension rod 2 under the action of the thread of the threaded rod 10, thereby releasing the fixed state of the device on the floor.

[0041] Carefully lift the equipment from the floor and move it to a safe place to avoid damage to the components caused by collision. Then disassemble the components in order, first remove the rubber anti-slip cover 22, check whether it is worn or deformed, and replace it in time if there is any problem; then unscrew the leveling frame 21 and the adjustment rod 20, clean the dust and debris attached to the threaded part, and check whether there is any damage such as thread slippage; then unscrew the bottom cover 6, clean the dust and concrete debris accumulated in the groove 5, check the wear and deformation of the transmission rod 7, bevel gear set, threaded rod 10, moving block 11 and other limit assembly components, and add lubricating oil or repair and replace them if necessary.

[0042] Calibrate and maintain the measuring device 4 to ensure that its measurement accuracy meets the requirements. Clean the guide hole 3 to remove dust, concrete debris, etc. attached during the measurement process to ensure that the measuring device 4 can slide freely in the guide hole 3 when used next time. Finally, keep all parts properly for next use.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
