Description

Technical Field

[0001] The utility model relates to the technical field of concrete measurement, in particular to a concrete thickness measuring tool. Background Art

[0002] The thickness of concrete is directly related to its bearing capacity. Sufficient thickness can provide the necessary structural strength and stability to prevent structural damage or collapse due to excessive load. By measuring the thickness of concrete, it can be verified whether it meets the design requirements, thereby ensuring the overall safety of the building structure. Therefore, in construction projects, measuring the thickness of concrete is an important part of ensuring project quality.

[0003] Traditionally, one surveyor holds a transmitting probe with an extension rod against the measuring point at the bottom of the floor slab, while another surveyor holds a receiving probe at the measuring point at the top of the floor slab and slowly moves the receiving probe to the accurate position so that the receiving probe is directly above the transmitting probe before measurement can be performed. This is rather cumbersome and requires precise movement of the receiving probe to directly above the transmitting probe, which increases the difficulty and complexity of the operation and reduces measurement efficiency.

[0024] Combined with attachment Figure 1 , Attachment Figure 3 and attached Figure 4 A concrete thickness measuring tool comprises a measuring box 1 and a motor box 2, wherein the motor box 2 is provided with a motor 3, the measuring box 1 is provided with a bidirectional screw 4 which is rotatably connected and driven by the motor 3, and both ends of the bidirectional screw 4 are provided with a threaded moving block 5, one side of the measuring box 1 is provided with a through slot 8, and the other side of the moving block 5 is provided with a connecting column 9 which passes through the through slot 8 and extends to the outside, an extension rod 10 which can adjust the extension length is inserted in the connecting column 9, and a plurality of evenly distributed limiting holes 11 are provided on the extension rod 10, and a fastening bolt 12 which passes through the limiting hole 11 is inserted on one side of the connecting column 9, and one side of the fastening bolt 12 is locked by a fastening nut connected by a thread.

[0025] Through the above structure, the motor 3 drives the bidirectional screw 4 to rotate continuously, and the moving blocks 5 located at both ends of the bidirectional screw 4 drive the connecting column 9 to move up and down, which is suitable for measuring the thickness of concrete of different thicknesses, and is convenient for flexibly adjusting the extension length of the extension rod 10, which is convenient for measuring different locations and has high measurement accuracy.

[0026] Combined with attachment Figure 3 A guide structure is provided on one side of the moving block 5 , and the guide structure includes a slider 6 arranged on one side of the moving block 5 , and a slide groove 7 used in conjunction with the slider 6 is provided on the inner wall of the motor box 2 .

[0027] Through the above structure, the slider 6 and the slide groove 7 can be used to guide and limit the moving block 5 to ensure that it can move up and down smoothly. The structure is simple and easy to implement.

[0028] Example 2

[0029] Combined with attachment Figure 1 and attached Figure 2 A detachable receiving probe 14 is provided on one side of the upper extension rod 10 , and a detachable transmitting probe 15 is provided on one side of the lower extension rod 10 for use with the receiving probe 14 .

[0030] Through the above structure, the receiving probe 14 and the transmitting probe 15 are always on the same vertical line, and there is no need for the detection personnel to move back and forth for alignment, which is convenient to operate and has high measurement efficiency.

[0031] Combined with attachment Figure 5 A fixing column 13 is provided on one side of the receiving probe 14 and the transmitting probe 15, and arc-shaped plates 16 are provided at both ends of one side of the extension rod 10 for cooperating with each other and clamping the fixing column 13. One side of the arc-shaped plate 16 is fixed together by a locking bolt 17 and a locking nut.

[0032] Through the above structure, the receiving probe 14 and the transmitting probe 15 can be detached and used in various ways.

[0033] Combined with attachment Figure 1 A display panel 18 electrically connected to the receiving probe 14 is provided on one side of the motor box 2 , and a handle 19 is provided on the top of the motor box 2 .

[0034] With the above structure, the entire device can be easily lifted up using the handle 19, making it convenient to use. Moreover, the measurement data can be displayed in real time on the display panel 18 for easy viewing.

[0035] When the utility model is implemented:

[0036] First, the surveyor holds the handle 19 so that the entire device is located on one side of the concrete floor, and slowly moves the measuring box 1 close to one side of the concrete floor. Then, the motor 3 is started, and the motor 3 drives the bidirectional screw 4 to rotate continuously. The moving blocks 5 at both ends of the bidirectional screw 4 drive the connecting column 9 to move under the limit of the slider 6 and the slide groove 7, so that the receiving probe 14 is close to the top of the floor, and the transmitting probe 15 is close to the bottom of the floor.

[0037] Next, the receiving probe 14 receives the signal sent by the transmitting probe 15 and transmits the detected thickness data directly to the display panel 18 for easy viewing.

[0038] Since the receiving probe 14 and the transmitting probe 15 are always on the same vertical line, the receiving probe 14 is always accurately located directly above the transmitting probe 15, and there is no need for the measurement personnel to move back and forth for alignment, which is convenient to operate and has high measurement efficiency.

[0039] When it is necessary to measure other positions, first unscrew the fastening bolt 12 and the fastening nut, stretch the extension rod 10 outward to the appropriate position, then pass the fastening bolt 12 through the limit hole 11, and lock it with the fastening nut, so as to facilitate the measurement of the thickness of the floor concrete at different positions with high measurement accuracy.

[0040] Finally, since the receiving probe 14 and the transmitting probe 15 are clamped between the arc-shaped plates 16 through the fixing columns 13, a detachable function is achieved, which is convenient for separate measurement and use, and the usage is flexible.
