Description

Technical Field

[0001] This utility model relates to the field of composite slab thickness detection technology, specifically a device for detecting the thickness of concrete composite slabs. Background Technology

[0002] In the construction and quality inspection of prefabricated buildings, the thickness of concrete composite slabs is a core acceptance indicator, directly affecting the structural load-bearing safety and service performance. Currently, commonly used thickness measuring devices are mostly rulers, calipers, or simple thickness gauges. Due to structural design limitations, the measurement depth is generally limited, and the measuring end length is fixed. Since concrete composite slabs are mostly large-sized panels, existing devices can only conveniently measure the thickness of the edges or near the outer side of the slab. When measuring the thickness of the middle area of ​​the slab, the measuring end cannot extend to the center, making measurement impossible. Therefore, this application proposes a concrete composite slab thickness measuring device to solve the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-3As shown, this utility model provides a technical solution: a concrete composite slab thickness detection device, including a handle 1, a positioning seat 2 fixedly installed on the left end of the handle 1, a pull rod 3 and a scale rod 4 with scale lines sliding in two sliding holes on the positioning seat 2 respectively, scale lines are provided on multiple surfaces of the scale rod 4, and the starting point of the scale line on the scale rod 4 is located on the top side, an upper measuring rod 5 is fixedly installed on the top of the pull rod 3 and the scale rod 4, a lower measuring rod 6 is fixedly installed on the left end of the positioning seat 2, and the upper measuring rod 5 and the lower measuring rod 6 are symmetrically distributed, and two symmetrically distributed bonding pieces 7 are fixedly installed on the left end of the upper measuring rod 5 and the lower measuring rod 6, a spring 8 is sleeved on the bottom side of the pull rod 3, and the upper and lower ends of the spring 8 are respectively connected to the bottom end of the positioning seat 2 and the pull rod 3. Under the push of the spring 8, the pull rod 3 slides downward in the sliding hole on the positioning seat 2. After the lower bonding piece 7 is bonded to the bottom side of the composite slab, the lever 9 is slowly released, and the pull rod 3 is driven by the spring 8. The upper measuring rod 5 slides down until the upper bonding piece 7 is in close contact with the upper surface of the plate. The two bonding pieces 7 can then be stably bonded to the upper and lower surfaces of the plate. By observing the scale line on the scale rod 4, and taking the top starting point as a reference, the scale value corresponding to the position on the upper side of the positioning seat 2 is read. This value is the thickness of the middle position of the laminated plate to be tested. After the measurement is completed, the lever 9 is moved again to move the two bonding pieces 7 away from each other. The device can then be removed. The lever 9 is fixedly installed at the bottom of the scale rod 4. The lever 9 is located directly below the handle 1, making it easy to hold the handle 1 and move the lever 9 upward with your fingers. By holding the handle 1 and moving the lever 9 located directly below the handle upward with your fingers, the scale rod 4 and the connected upper measuring rod 5 slide upward, so that the upper bonding piece 7 is away from the lower bonding piece 7, leaving enough space to accommodate the thickness of the plate. Then, the gap between the two bonding pieces 7 is aligned with the side of the laminated plate, so that the two bonding pieces 7 can be inserted into the upper and lower measurement positions of the laminated plate.

[0021] Both the upper measuring rod 5 and the lower measuring rod 6 are telescopic rods, including a cylindrical rod on the right and a pull rod on the left. The pull rod slides inside the cylindrical rod, and the cylindrical rod and the pull rod are fixed together by bolts. The distance between the bonding piece 7 and the positioning seat 2 can be adjusted by stretching the upper measuring rod 5 and the lower measuring rod 6. The distance between the bonding piece 7 and the positioning seat 2 can be adjusted by at least 50cm by the telescopic rod. The maximum adjustable distance between the two bonding pieces 7 is not less than 10cm. The two bonding pieces 7 can be moved closer or further apart by sliding the pull rod 3 in the sliding hole on the positioning seat 2. The starting point of the scale line on the scale rod 4 is set on the top side. When the two bonding pieces 7 are bonded together, the starting point of the scale line on the scale rod 4 is at the same height as the bonding surface of the two bonding pieces 7. The upper surface of the lower bonding piece 7 is at the same height as the top opening of the sliding hole on the positioning seat 2, ensuring that the value of the scale is matched with the distance between the bonding pieces 7.

[0022] The operational steps for this application are as follows:

[0023] Hold handle 1 and flick the lever 9 located directly below the handle upwards. This will cause the scale rod 4 and the connected upper measuring rod 5 to slide upwards, moving the upper bonding piece 7 away from the lower bonding piece 7. Sufficient space should be left to accommodate the thickness of the board. Align the gap between the two bonding pieces 7 with the side of the laminated board. Then, insert the two bonding pieces 7 into the measurement positions on the upper and lower sides of the laminated board. Attach the lower bonding piece 7 to the bottom side of the laminated board. Slowly release the lever 9. Under the push of the spring 8, the pull rod 3 will cause the upper measuring rod 5 to slide downwards until the upper bonding piece 7 is firmly against the upper surface of the board. After both bonding pieces 7 are stably attached to the board surface, observe the scale line on the scale rod 4. Using the top starting point as a reference, read the scale value corresponding to the position of the positioning seat 2. This value is the thickness of the middle part of the laminated board to be measured. After measurement, flick the lever 9 again to move the two bonding pieces 7 away from each other, and then remove the device.
