[0002] The thickness of cast-in-place floor slabs and walls is an important indicator for assessing the safety performance of buildings. The traditional method of drilling measurement not only has large errors, but also belongs to the category of damage measurement, which is both time-consuming and laborious. The floor thickness gauge breaks through the traditional testing method and achieves unimaginable testing accuracy.

[0003] When the floor thickness gauge is in use, at least two workers are required to work on the upper and lower levels of the floor. The lower worker supports the top surface of the transmitting probe on the bottom surface of the floor, and the upper worker uses the receiving probe to continuously move the bottom surface of the floor until the position where the measured value on the display panel is the smallest is recorded as the thickness of the floor. However, the concrete on the floor surface is prone to the phenomenon of cement slurry residue and other debris that is not cleaned up. When foreign particles are generated, the transmitting probe is supported by them, which will affect the measurement of the floor thickness, thereby hindering the accurate measurement of the floor thickness.

DETAILED DESCRIPTION

[0017] See also Figure 1-Figure 4 The utility model provides the following technical solutions: it includes a transmitting probe 1, the bottom end of the transmitting probe 1 is detachably connected to an extension rod 11, a mounting ring 2 is provided above the transmitting probe 1, and two corresponding slide grooves 21 are provided on the top of the mounting ring 2, the inner wall of the slide groove 21 is slidably connected to a slide rod 22, the bottom end of the slide rod 22 is fixedly connected to a connecting plate 23, a spring 231 is fixedly connected between the connecting plate 23 and the inner wall of the mounting ring 2, the outer wall of the mounting ring 2 is fixedly connected to a fixing plate 24 corresponding to the slide rod 22, one end of the slide rod 22 is fixedly connected to a pull rope 27, the pull rope 27 passes around one end of the fixing plate 24, the outer wall of the extension rod 11 is slidably connected to an inner sleeve 33, and the inner sleeve 33 is fixedly connected to the pull rope 27.

[0018] In this embodiment: the transmitting probe 1 is used to measure the thickness of the floor slab by supporting the top end surface of the transmitting probe 1 on the bottom end surface of the floor slab, and then cooperating with the receiver on the floor slab to correspond to the transmitting probe 1, and when the transmitting probe 1 is supported on the bottom end of the floor slab by using the extension rod 11, after the bottom end surface of the floor slab is demolded, after the concrete casting formwork is demolded, the concrete on the floor slab surface is prone to produce cement slag and other debris that are not cleaned up. When foreign particles are generated, when the top end surface of the transmitting probe 1 is directly supported on the bottom end surface of the floor slab, it is difficult for the surface of the transmitting probe 1 to fit closely with the floor slab, which is not conducive to supporting the transmitting probe 1 on the floor slab, thereby causing The vertical distance between the receiver and the transmitting probe 1 is easily affected. At this time, the mounting ring 2 can be supported on the floor surface first, and the sliding rod 22 slidably connected to the inner wall of the sliding groove 21 opened on the top of the mounting ring 2 is level with the top surface of the mounting ring 2, so that when the mounting ring 2 is supported on the floor plate, the sliding rod 22 can be synchronously supported on the bottom end surface of the floor plate. At the same time, when the sliding rod 22 contacts the bottom end surface of the floor, the connecting plate 23 fixedly connected to the bottom end of the sliding rod 22 and the spring 231 fixedly connected between the inner wall of the mounting ring 2 can support one end of the sliding rod 22, so that the two corresponding sliding rods 22 can dock with each other under the support of the spring 231. After the two sliding rods 22 are docked, The device can be rotated as a whole, so that the mounting ring 2 drives the slide bar 22 to rotate. After the slide bar 22 rotates, since its top surface fits with the bottom end surface of the floor slab, the slide bar 22 can clean the cement slurry residue, and the concrete bulge that cannot be cleaned can limit the slide bar 22, so that the staff can properly adjust the installation position of the transmitting probe 1. After the bottom end surface of the floor slab is detected, the inner sliding sleeve 33 slidably connected to the outer wall of the extension rod 11 can slide downward, so that the pull rope 27 fixedly connected to the top end of the inner sliding sleeve 33 can be subjected to its traction and move downward. At the same time, one end of the fixed plate 24 fixedly connected to the outer wall of the mounting ring 2 is fixedly connected The guide rod 26 fixedly connected to the mounting plate 25 is wound around the pull rope 27, so that after one end of the pull rope 27 is connected to one end of the slide rod 22, the slide rod 22 is subjected to external tension, overcoming the elastic supporting force of the spring 231, so that the distance between the two slide rods 22 is increased, and after the slide rod 22 and the transmitting probe 1 are misaligned, the extension rod 11 can be pushed to support the transmitting probe 1 on the bottom end surface of the floor slab after inspection, so that when the device detects the thickness of the floor slab, it can effectively prevent the accuracy of the floor slab thickness detection from being affected by cement slurry residue and other debris, thereby being not conducive to accurately judging the quality of the floor slab after pouring, so that the device can ensure the safety of floor construction.

[0019] The outer wall of the inner sleeve 33 is slidably connected to the outer sleeve 3, and the outer wall of the outer sleeve 3 is fixedly connected to the docking rod 31, and a support rod 32 is fixedly connected between the docking rod 31 and the mounting ring 2; the docking rod 31 and the outer wall of the outer sleeve 3 to which the inner sleeve 33 is slidably connected correspond to the mounting ring 2 up and down, so that the mounting ring 2 is supported on the outside of the transmitting probe 1 by the two support rods 32, and the height of the mounting ring 2 can be adjusted by pushing the outer sleeve 3 up and down, so that when the bottom end surface of the floor slab needs to be inspected and cleaned, the mounting ring 2 can be supported on the floor slab, and at the same time, it can slide down so that the height of the mounting ring 2 is lower than the height of the transmitting probe 1. When the bottom end surface of the floor slab is smooth, the thickness of the floor slab can be directly inspected by the transmitting probe 1.

[0020] A limiting groove 211 is provided at the connection between the slide groove 21 and the slide rod 22, and a limiting block 221 matching the limiting groove 211 is fixedly connected to the slide rod 22; the limiting groove 211 provided at the connection between the slide groove 21 and the slide rod 22 is used to limit the limiting block 221 fixedly connected to the slide rod 22, so that the slide rod 22 can slide horizontally while sliding on the top of the mounting ring 2, so that the slide rod 22 can fit the floor surface.

[0021] One end of the fixed plate 24 is fixedly connected to a mounting plate 25, and a guide rod 26 for limiting the pull rope 27 is fixedly connected between the mounting plates 25; the mounting plate 25 fixedly connected to one end of the fixed plate 24 is used to install and fix the guide rod 26, so that the pull rope 27 can connect one end of the sliding rod 22 with the support rod 32, so that the sliding rod 22 can be pulled horizontally outward by the pull rope 27.

[0022] The transmitting probe 1 corresponds to the center of the mounting ring 2, the top of the sliding rod 22 is flush with the top of the mounting ring 2, and the transmitting probe 1 corresponds to the mounting ring 2 horizontally; the transmitting probe 1 corresponds to the center of the mounting ring 2, so that the transmitting probe 1 can be supported at the bottom end surface of the floor slab detected by the sliding rod 22, and the top of the sliding rod 22 is flush with the mounting ring 2, so that the sliding rod 22 can fit with the bottom end surface of the floor slab.

[0023] The working principle and use process of the utility model are as follows: by supporting the mounting ring 2 on the bottom end surface of the floor slab, the two sliding rods 22 slidably connected at the top of the mounting ring 2 can be butt-connected under the support of the spring 231. At this time, the device as a whole can be rotated to enable the mounting ring 2 to drive the sliding rod 22 to rotate. After the sliding rod 22 rotates, its top surface is in contact with the bottom end surface of the floor slab, so that the sliding rod 22 can clean the cement slurry residue, and the concrete protrusion that cannot be cleaned can limit the sliding rod 22, so that the staff can properly adjust the installation position of the transmitting probe 1. After detecting the bottom end surface of the floor slab, the inner sliding sleeve 33 is pulled downward to drive the pull rope 27 to pull the sliding rod 22 outward, making way for the rising of the transmitting probe 1, so that the transmitting probe 1 can be supported on the bottom end surface of the floor slab, so that when the device detects the thickness of the floor slab, it can effectively prevent the floor slab thickness detection accuracy from being affected by debris such as cement slurry residue and causing deviation, which is not conducive to accurately judging the quality of the floor slab after pouring, so that the device can ensure the safety of floor construction.
