Description

Technical Field

[0001] The invention belongs to the technical field of concrete thickness measurement and control, and in particular relates to a device and method for measuring the thickness of a concrete floor slab. Background Art

[0002] Concrete thickness measurement is an important part of detecting the size of concrete structures, ensuring the structural safety of buildings and preventing leakage and other usage functions, while verifying the actual conditions of reinforced concrete structural components.

[0003] The concrete floor thickness measuring devices and methods currently available on the market have the following problems when used: 1. When using the traditional concrete floor thickness measuring device, after determining the pouring range, pour an appropriate amount of concrete and flatten it, then take out the scale or ruler for measurement. This makes it impossible to effectively control the surface flatness of the concrete floor, and the thickness of the floor and the thickness of the steel bar protection layer cannot be controlled either. Therefore, the quality control is weak during use; 2. When most concrete floor thickness measuring devices are used, it is often necessary to install an iron plate on the outside of the measuring device. Before pouring concrete, you need to support the measuring device with one hand and support the height of the iron plate with the other hand. Finally, you can pour the concrete into the pouring area. However, this operation is more complicated and inconvenient to adjust at any time. Therefore, it is inconvenient to operate when used. Summary of the invention

After moving to the appropriate position, it can be placed on a plane. In order to make measurement more convenient, an anti-skid sleeve 3 is installed on the top of the steel bar body 1, and a pointed rod 2 is provided at the bottom of the steel bar body 1. The steel floor slab is slidably connected to the outside of the steel bar body 1. When the measuring device needs to be used for measurement, the pointed rod 2 is taken out, and a threaded column 6 is connected to one end of the pointed rod 2. Secondly, a threaded groove 7 is opened at the bottom of the steel bar body 1, and the threaded rod 13 is threadedly connected to the inside of the threaded groove 7. In this way, the steel bar body 1 and the pointed rod 2 can be connected and fixed. Then the anti-skid sleeve 3 is taken out, and a binding tape is wrapped around the outside of the protective sleeve, and the inside of the anti-skid sleeve 3 is connected to the plug rod 4. The plug rod 4 is inserted into the slot 5 at the other end of the steel bar body 1. Then the height of the iron sheet floor slab 10 can be adjusted, and the iron sheet floor slab 10 is installed on the outside of the steel bar body 1, and the threaded rod 13 is installed inside the ring body 11. , the nut 14 is connected to the outer thread of the threaded rod 13, and the nut 14 on the outer side of the threaded rod 13 is first screwed in the opposite direction, so that the threaded rod 13 moves in the arc groove 12, and at the same time drives the slider 8 inside the iron floor 10 to move up and down inside the slide groove 9. After the staff adjusts the iron floor 10 to a suitable height, the nut 14 on the outer side of the threaded rod 13 is screwed, and the anti-slip sleeve 3 on the outer side of the steel bar body 1 is held, and then the pointed rod 2 is inserted into the concrete. This is not only simple and efficient to operate, but also keeps the concrete in place. The bottom of the iron sheet floor 10 can be used, which can effectively control the flatness of the concrete floor surface, and the thickness of the floor and the thickness of the steel bar protective layer can be determined. The quality is well controlled during use. When the position is found to be inappropriate, it can be adjusted as it is inserted. It is convenient to operate during application. Secondly, in order to avoid rust on the nut 14 and the threaded rod 13, take out the protective cover 17, and then insert the metal rod 19 at the bottom of the protective cover 17 into the magnetic suction groove 20, which can be adsorbed and fixed by a strong magnet, and the fasteners can also be protected at the same time.
