A tool for measuring the thickness of cast-in-place slabs during the pouring process

Abstract

The present invention relates to the field of floor thickness measuring tools, and more specifically, to a floor thickness measuring tool for a cast-in-place floor during casting, comprising a measuring compression bin and a reading spring bin, wherein the reading spring bin is fixedly sleeved on the top of the measuring compression bin, and the end of the reading spring bin away from the measuring compression bin is fixedly connected to a top plate, a through slot is provided through the center of the circle at the top of the measuring compression bin, and a first plug cone and a second plug cone are fixedly connected to the bottom of the measuring compression bin, and the ends of the first plug cone and the second plug cone away from the measuring compression bin are pointed, and a measuring transmission rod is slidably inserted inside the through slot. By replacing the fiber insertion rod in a traditional measuring tool with an implicit measuring transmission rod and setting the scale line on the outer wall of the reading spring bin, the implicit measuring transmission rod can be effectively prevented from directly contacting the concrete and causing cement slurry to adhere to the rod because the rod is slidably inserted inside the measuring compression bin.

Description

Technical Field

[0001] The invention relates to the field of floor slab thickness measuring tools, in particular to a floor slab thickness measuring tool during the casting process of a cast-in-place floor slab. Background Art

[0002] At present, actual measurement has become a means of normalized physical quality control in real estate everywhere, and floor thickness and indoor net height are must-check items in the actual measurement. Against the background of actual measurement of real estate agencies, various tools for measuring floor thickness and floor elevation have been derived.

[0003] In the process of measuring the thickness of the concrete floor slab during the pouring process, the existing floor slab thickness measuring tools are mostly used to directly insert the fiber-inserting rod with a pointed bottom through the cylinder of the fiber-inserting tube component into the interior of the concrete floor slab, and then measure and read the thickness of the concrete floor slab through the scale of the fiber-inserting rod. However, since it is necessary to accurately ensure that the bottom of the fiber-inserting rod is flush with the bottom of the fiber-inserting tube component in each measurement, accurate measurement can be achieved, and no reset structure is provided, so that the fiber-inserting rod needs to be manually calibrated before each use, which is not only inconvenient to use the measuring tool, but also leads to low measurement accuracy; in addition, after the fiber-inserting rod passes through the cylinder of the fiber-inserting tube component and is inserted into the interior of the concrete floor slab, the rod wall of the fiber-inserting rod and the bottom of the support plate of the fiber-inserting tube component will be attached to the cement slurry in the concrete, and when the fiber-inserting rod is pulled back into the cylinder of the fiber-inserting tube component, the cement slurry on the rod wall of the fiber-inserting rod will also adhere to the inner wall of the cylinder, and when the cement slurry solidifies, the tool will be damaged and cannot be used again.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] like Figure 1-Figure 7 As shown, the present invention provides a floor thickness measuring tool during the casting process of a cast-in-place floor, comprising a measuring compression chamber 1 and a reading spring chamber 2, wherein the reading spring chamber 2 is fixedly sleeved on the top of the measuring compression chamber 1, and an end of the reading spring chamber 2 away from the measuring compression chamber 1 is fixedly connected to a top plate 3;

[0027] A through slot 6 is provided at the center of the top of the measuring compression chamber 1, and a first plug cone 7 and a second plug cone 8 are fixedly connected to the bottom of the measuring compression chamber 1. The ends of the first plug cone 7 and the second plug cone 8 away from the measuring compression chamber 1 are pointed ends, and a measuring transmission rod 10 is slidably inserted into the through slot 6;

[0028] The measuring transmission rod 10 is slidably inserted into the rod wall at one end of the inner side of the through groove 6, and a measuring transmission block 11 is fixedly connected thereto. A first groove 12 matching the measuring transmission block 11 is formed on the inner wall of the through groove 6. The measuring transmission block 11 is slidably connected inside the first groove 12, and a measuring ring 13 is fixedly connected to one end of the measuring transmission block 11 passing through the first groove 12. The measuring ring 13 is slidably sleeved on the outer wall of the measuring compression chamber 1, and a measuring sheet 14 is fixedly sleeved on the side wall of the outer circumference of the measuring ring 13.

[0029] One end of the measuring transmission rod 10 extending to the inside of the reading spring bin 2 is fixedly connected to a lifting plate 23, and the lifting plate 23 is slidably connected to the inside of the reading spring bin 2. A reading transmission block 15 is fixedly connected to the side wall of the outer circle side of the lifting plate 23. A second groove 16 is penetrated through the position of the reading transmission block 15 on the inner wall of the reading spring bin 2. The reading transmission block 15 is slidably connected to the inside of the second groove 16. One end of the reading transmission block 15 passing through the second groove 16 is fixedly connected to a reading ring 17, and the reading ring 17 is slidably sleeved on the outer wall of the reading spring bin 2. A scale 22 is provided on the outer wall of the reading spring bin 2. A second spring 21 is fixedly connected to the top of the lifting plate 23, and the other end of the second spring 21 is fixedly connected to the top plate 3.

[0030] The measuring piece 14 includes a first splicing plate 141 and a second splicing plate 142 which are symmetrically arranged. A clamping groove 143 is formed on the top of the adjacent ends of the first splicing plate 141 and the second splicing plate 142. A plug post 144 is fixedly connected to the inner wall of the clamping groove 143. A matching plug hole is formed on the outer wall of the measuring ring 13 corresponding to the plug post 144. A connecting rod 145 is provided between the first splicing plate 141 and the second splicing plate 142. A slot 146 is formed on the side wall of the first splicing plate 141 and the second splicing plate 142 corresponding to the connecting rod 145. The connecting rod 145 is connected to the measuring ring 13. One end of the connecting rod 45 inserted into the slot 146 is fixedly connected with a fixing ring 147, and a matching annular groove 148 is opened inside the slot 146 corresponding to the fixing ring 147. The fixing ring 147 is slidably connected inside the annular groove 148, and one side of the fixing ring 147 is fixedly connected with a first spring 149. The first spring 149 is sleeved on the rod wall of the connecting rod 145 inserted into the annular groove 148 at one end. The two splicing plates can be clamped on the outer wall of the measuring ring 13, thereby increasing the contact area between the measuring ring 13 and the concrete, so that the force effect of the measuring ring 13 is better.

[0031] A handle rod 4 is fixedly connected to the top of the top plate 3, and a handle pressing block 5 is fixedly connected to the other end of the handle rod 4. The diameter of the handle pressing block 5 is larger than the diameter of the handle rod 4. The handle pressing block 5 can make the handle rod 4 more comfortable when driving the reading spring chamber 2 to be pressed down.

[0032] A through hole 9 is formed through the top of the second insert cone 8 near the first insert cone 7 , and the through hole 9 is connected to the through groove 6 , so that the cement slurry poured into the through groove 6 along the first groove 12 can be discharged along the through hole 9 .

[0033] A sealing rod 18 is fixedly connected to the bottom of the reading transmission block 15, and the sealing rod 18 is slidably inserted into the second groove 16, and one end of the sealing rod 18 extending out of the second groove 16 is slidably connected to the outer wall of the measuring compression chamber 1, and the end of the sealing rod 18 away from the reading transmission block 15 is fixedly connected to the measuring ring 13. The sealing rod 18 can not only effectively prevent the cement slurry in the concrete from entering the interior of the reading spring chamber 2, but also effectively make the transmission support effect of the measuring transmission rod 10 better.

[0034] A sealing plate 19 is fixedly connected to the top of the measuring transmission block 11, and a corresponding adaption groove 20 is opened on the outer wall of the measuring compression chamber 1 corresponding to the sealing plate 19, and the sealing plate 19 is slidably connected to the inside of the adaption groove 20. The sealing plate 19 can effectively prevent the cement slurry in the concrete from being poured into the inside of the measuring compression chamber 1 along the first groove 12.

[0035] In the initial state, if Figure 1 As shown, the height of the scale 22 on the reading ring 17 and the reading spring bin 2 is the height of the cone at the bottom of the measuring compression bin 1. At this time, the elastic force of the second spring 21 pushes the lifting plate 23, the measuring transmission rod 10 and the measuring ring 13 to the zero position;

[0036] When using the tool for measurement, hold the handle pressing block 5 and place the tool on the concrete floor to be measured. At this time, the measuring piece 14 on the measuring ring 13 is horizontally located on the concrete. Press the handle pressing block 5 downward, and the handle pressing block 5 drives the reading spring bin 2 and the measuring compression bin 1 to move toward the direction of the concrete floor through the handle rod 4 and the top plate 3. As the measuring compression bin 1 moves downward, it is inserted into the interior of the concrete. At this time, the measuring piece 14 is located at the top of the concrete. As the measuring compression bin 1 continues to be inserted downward, the measuring ring 13 drives the measuring transmission rod 10 and the lifting plate 23 to move upward relative to each other through the measuring transmission block 11. The second spring 21 is compressed by force. When moving, the lifting plate 23 can drive the reading ring 17 to move upward relative to each other along the outer wall of the reading spring bin 2 through the reading transmission block 15. When the insertion cone is at the bottom, the thickness of the concrete can be obtained by reading the reading of the reading ring 17 on the scale 22.

[0037] After the measurement is completed and the device is pulled out, the elastic force of the second spring 21 can push the lifting plate 23 to reset. When the lifting plate 23 is subjected to the elastic force of the second spring 21, it can drive the measuring ring 13 to reset together through the measuring transmission rod 10. The measuring transmission rod 10, the measuring ring 13 and the sealing plate 19 can scrape off the cement on the inner and outer walls of the measuring compression chamber 1 during the resetting process.
