Description

Technical Field

[0001] This utility model relates to the field of building floor slab thickness testing, and more specifically, to building floor slab thickness testing equipment. Background Technology

[0002] Building floor slabs are horizontal load-bearing structures in buildings that separate upper and lower floors. They mainly bear floor loads (such as people, furniture, etc.) and transfer them to load-bearing walls or beams and columns. During the production of floor slabs, their thickness needs to be tested to prevent structural failure due to insufficient thickness.

[0003] A search revealed that Chinese patent CN220304442U discloses a "building floor slab thickness testing device, including a support rod and a fixing mechanism; the support rod has a guide groove on the right side of its outer arc surface, and a screw is rotatably connected to the inside of the guide groove via a bearing. The screw is threadedly connected to a threaded hole in the middle of a connecting plate, and the connecting plate is slidably connected to the inner wall of the guide groove. A pressure plate is movably fitted in the middle of the outer arc surface of the support rod, and the right end of the connecting plate is fixedly connected to the inner arc surface of the pressure plate; the fixing mechanism includes an installation rod, an adjusting plate, a hexagonal sliding column, a connecting seat, a limiting plate, and a chuck. The installation rod is rotatably connected to the inside of the support rod via a bearing. This building floor slab thickness testing device can limit and fix the support rod, replacing the traditional method of measuring by hand with a steel tape measure, reducing the workload of personnel while improving the accuracy of testing the thickness of building floor slabs. It has a simple structure and relatively low cost." However, it still has the following drawbacks: When this device is used to detect the thickness of the floor slab, it is necessary to use other equipment to take the reading. In addition, the device requires workers to operate it continuously during use, which makes it less practical.

[0004] Therefore, we made improvements and proposed a building floor slab thickness testing device. Utility Model Content

[0019] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] like Figure 1-5 As shown, this embodiment proposes a building floor slab thickness detection device, including a cylinder 1, a thickness detection mechanism 2 is arranged inside the cylinder 1, and a stabilizing component 3 is arranged inside the cylinder 1; like Figure 4 As shown, the thickness detection mechanism 2 includes a connecting hole 201, a bidirectional lead screw 202, a servo motor 203, a battery 204, a first clamping plate 205, a second clamping plate 206, a mounting plate 207, and a laser rangefinder 208. The connecting hole 201 is located on the side wall of the cylinder 1. The bidirectional lead screw 202 is rotatably connected to the inside of the cylinder 1. The servo motor 203 is bolted to the top of the cylinder 1 and coaxially arranged with the bidirectional lead screw 202. The battery 204 is bolted to the inner wall of the cylinder 1 and electrically connected to the servo motor 203. The first clamping plate 205 and the second clamping plate 206 are respectively threaded to the two ends of the bidirectional lead screw 202. The mounting plate 207 is fixedly connected to the cylinder 1. On the side wall of the first clamping plate 205, a laser rangefinder 208 is bolted to the side wall of the mounting plate 207. The laser rangefinder 208 is existing technology and will not be described in detail here. When in use, the worker picks up the device, starts the servo motor 203, and moves the first clamping plate 205 and the second clamping plate 206 away from each other. Then, the worker moves the device to the floor slab, starts the servo motor 203, and reverses its output to move the first clamping plate 205 and the second clamping plate 206 closer together until the first clamping plate 205 and the second clamping plate 206 clamp the floor slab. At this time, the worker turns off the servo motor 203 and then reads the information on the laser rangefinder 208 to determine the thickness of the floor slab.

[0023] like Figure 4 As shown, the stabilizing assembly 3 includes stabilizing plates 301 and stabilizing rods 302. The two stabilizing plates 301 are fixedly connected to the side walls of the first clamping plate 205 and the second clamping plate 206, respectively. The stabilizing rod 302 is fixedly connected to the inside of the cylinder 1, with one end of the stabilizing rod 302 passing through both stabilizing plates 301 and slidably connected to them. When the first clamping plate 205 and the second clamping plate 206 are raised or lowered, the stabilizing plates 301 move along the stabilizing rods 302, greatly improving the stability of the first clamping plate 205 and the second clamping plate 206.

[0024] like Figure 1 As shown, the top and bottom of the cylinder 1 are both provided with discharge holes 4, and there are four discharge holes 4 distributed circumferentially along the central axis of the cylinder 1. When measuring building floor slabs, some solid particles with smaller diameters will enter the interior of the cylinder 1 through the connecting hole 201. At this time, the solid particles can be easily discharged through the discharge holes 4.

[0025] like Figure 5 As shown, several rectangular grooves 5 are provided on the side walls of the first clamping plate 205 and the second clamping plate 206, and friction pads 6 are adhered to the inside of each rectangular groove 5. During use, the friction pads 6 can increase the friction between the first clamping plate 205 and the second clamping plate 206 and the floor slab, thereby improving the accuracy of measurement.

[0026] like Figure 2 As shown, a fixing block 7 is fixedly connected to the outer wall of the cylinder 1, and a level 8 is provided on the top of the fixing block 7. A handle 9 is fixedly connected to the side wall of the cylinder 1 away from the connecting hole 201. The device can be easily moved by the handle 9, and the level 8 can be used to check whether the device is level, thus improving the accuracy of measurement.

[0027] like Figure 1 As shown, both the first clamping plate 205 and the second clamping plate 206 are made of wear-resistant steel, and both the outer walls of the first clamping plate 205 and the second clamping plate 206 are coated with tungsten carbide. Wear-resistant steel has high hardness, and the carbide coating can also resist scratches from concrete aggregate, preventing the surfaces of the first clamping plate 205 and the second clamping plate 206 from being worn.

[0028] like Figure 2 As shown, the bottom of the second clamping plate 206 is provided with a plurality of bristles 10, which are evenly distributed along the length of the second clamping plate 206. When in use, the user picks up the device and uses the bristles 10 to clean dust or small particles on the floor surface.

[0029] Specifically, when using this building floor slab thickness detection equipment: The device is lifted by handle 9, the servo motor 203 is started, causing the bidirectional lead screw 202 to rotate, thereby moving the first clamping plate 205 and the second clamping plate 206 away from each other. At this time, the stabilizing rod 302 can improve the stability of the first clamping plate 205 and the second clamping plate 206 during lifting and lowering. Then, the device is moved to the floor slab, and the servo motor 203 is started again, causing its output end to reverse, bringing the first clamping plate 205 and the second clamping plate 206 closer together until they clamp the floor slab. At this point, the servo motor 203 is turned off, and the laser rangefinder 208 is started. By reading the information on the laser rangefinder 208, the thickness of the floor slab can be determined.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
