Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of concrete construction, and in particular relates to a concrete thickness detection tool. Background Art
[0002] Concrete is generally divided into two categories: wet and dry. It can be constructed by spraying, such as underground mine tunnel shotcrete. Wet shotcrete uses a certain mix ratio to mix cement, coarse and fine aggregates and water together. Then, with the help of various types of wet sprayers, the mixed concrete is transported to the nozzle through a feed hose, and liquid accelerators are added at the nozzle. Compressed air is used to replenish energy to form a material bundle of concrete, which is sprayed from the nozzle onto the surrounding rock surface.
[0003] After concrete construction, the thickness of the sprayed concrete needs to be measured to check whether it meets the construction requirements. However, the test should be done after the concrete solidifies. A drilling rig is used to drill the test hole, and then a ruler or other tools are used to measure. If unqualified points are detected, the concrete will be sprayed again, which will not only delay the construction progress to a certain extent, but may also have a certain impact on the overall construction quality. However, there is currently no tool to quickly detect the thickness of concrete during the spraying construction process, which is inconvenient for construction personnel to operate and cannot ensure that the thickness of the on-site sprayed concrete meets the design requirements in a timely manner.

[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0032] Please refer to Figure 1In a first aspect of the present application, a concrete thickness detection tool is provided, which includes: a support assembly 110, a measuring rod 120 and a detector 140. The support assembly 110 is used to support on the concrete surface. The support assembly 110 is provided with a through cavity 110a running through both ends. If the support assembly 110 adopts a thicker plate structure, a block structure or other structural forms, as long as the support assembly 110 can be supported on the surface of an object; one end of the measuring rod 120 is located in the through cavity 110a, and this end serves as the end inserted into the concrete. When not in use, it is located in the through cavity 110a in the support assembly 110. The through cavity 110a serves as a storage position for one end of the measuring rod 120, reducing the damage of this end of the measuring rod 120 to the outside, such as damage to the operator. The other end of the measuring rod 120 is located outside the through cavity 110a, and this end extends outward to the outside of the through cavity 110a, which is convenient for operation The operator holds it for operation, and the measuring rod 120 is movably connected to the support assembly 110. There are many ways of movable connection. For example, the support assembly 110 is provided with inner edges along the inner wall at both ends of the through cavity 110a, and the end of the measuring rod 120 located in the through cavity 110a is provided with convex edges or protrusions around the periphery. The size of the protrusion or convex edge is larger than the diameter at the inner edge. In this way, when the measuring rod 120 moves relative to the support assembly 110, one end can always be stuck in the support assembly 110, thus forming a movable connection, and it can also be set to other structural forms; the detector 140 is used to detect the moving distance of the measuring rod 120. The detector 140 is installed on the measuring rod 120. The detector 140 can use an instrument for detecting distance, with a position sensor, an infrared sensor or other displacement sensor. The detector 140 can purchase an existing detection instrument and bind it to the measuring rod 120, such as fixing it with screws. Among them, the measuring rod 120 is movable relative to the supporting assembly 110 along the in and out direction of the through cavity 110a. When moving, one end of the measuring rod 120 can extend from the through cavity 110a, and then be inserted into the concrete until it reaches the hard layer position. The moving position of the measuring rod 120 can be directly obtained through the detector 140, thereby obtaining the depth of the concrete.
[0033] In the prior art, when testing the thickness of concrete, it is necessary to wait for the concrete to solidify, then use a drill to drill a testing hole, and use a ruler or other tool 100 to measure, which has a long testing cycle and consumes a lot of work. However, the present application can support the concrete surface through the support assembly 110, and then use the measuring rod 120 to move and extend out of the through cavity 110a, and measure the moving distance of the measuring rod 120 through the detector 140, so that the depth of the measuring rod 120 inserted into the concrete can be obtained in real time, until the end of the measuring rod 120 abuts against the hard structure cast by the concrete, and the measuring rod 120 stops moving. The thickness value of the concrete can be quickly obtained directly through the relative movement of the measuring rod 120, and the concrete thickness can be detected in real time during the spraying concrete construction process, so as to achieve the purpose of rapid detection. The tool 100 of the present application can be inserted into the concrete before the concrete is completely solidified, and the concrete thickness detection can be completed quickly to ensure that the concrete thickness meets the standard, and the tool 100 is portable and convenient for on-site storage and transfer.
[0034] In an optional embodiment, an elastic connector 130 is further included, which is an elastic part that can provide elastic force and buffer. The two ends of the elastic connector 130 are respectively connected to the support assembly 110 and the measuring rod 120. The elastic connector 130 realizes the movable connection between the support assembly 110 and the measuring rod 120. The elastic connector 130 is elastic and can change the elastic force by stretching or shortening. The elastic connector 130 also plays a connecting role, so that the support assembly 110 and the measuring rod 120 can never be separated. At the initial stage, the elastic connector 130 can also maintain the relative position of the measuring rod 120 and the support assembly 110 to ensure that the measuring rod 120 does not extend out at the initial stage. When the measuring rod 120 moves, the elastic connector 130 interacts with the measuring rod 120. For example, when the measuring rod 120 moves and extends out of the through cavity 110a, the elastic connector 130 compresses and applies an elastic force to push the measuring rod 120 back. The opposite direction can also act on each other, thereby shortening or lengthening the length of the elastic connector 130. In an optional embodiment, the elastic connector 130 is a spring, one end of which is embedded in one end of the support assembly 110, and the other end of the spring is fixed to the measuring rod 120 and can be clamped, or fixed by welding. The elastic connector 130 can also use other elastic parts, such as a disc spring.
[0035] In an optional embodiment, the support assembly 110 includes a support plate 111 and a tubular cavity 112, one end of the tubular cavity 112 is connected to one side of the support plate 111, and the other end of the tubular cavity 112 is movably connected to the measuring rod 120. The other side of the support plate 111 is used to support the concrete surface. The support plate 111 is plate-shaped. When the support plate 111 acts on the concrete surface, it can reduce the pressure on the concrete layer. The other end of the tubular cavity 112 is connected to the measuring rod 120 through an elastic connector 130. The tubular cavity 112 is a tubular structure, and one end of the measuring rod 120 is inserted and stored in the tubular cavity 112. In an optional embodiment, the support plate 111 is provided with a through hole 111a for the measuring rod 120 to extend out. The through hole 111a is the basic position for the end of the measuring rod 120 to extend out of the support plate 111, and can be used as a reference for measuring the depth of concrete. Initially, the end of the measuring rod 120 is just at the through hole 111a and does not exceed the support plate 111. The tubular cavity 112 is provided with a channel 112a passing through both ends, and one end of the measuring rod 120 is placed in the channel 112a. The through hole 111a and the channel 112a are connected and combined together to form a through cavity 110a.
[0036] In an optional embodiment, the measuring rod 120 includes an insertion section 121, an intermediate section 122 and an operating section 123. The two ends of the intermediate section 122 are respectively connected to the insertion section 121 and the operating section 123. The outer diameter of the intermediate section 122 is smaller than the size of the through cavity 110a, so that the operating section 123 can move quickly. The outer diameter of the operating section 123 is larger than the outer diameter of the intermediate section 122, so that it is convenient for operators to use. When in use, the insertion section 121 is placed in the through cavity 110a, and the insertion section 121 is always in the tubular cavity 112 in whole or in part. The intermediate section 122 can enter the through cavity 110a as the insertion section 121 is inserted into the concrete. The insertion section 121 has a smaller outer diameter at the end, which is convenient for the insertion section 121 to penetrate into the concrete, making up for the lack of inspection during the wet shotcrete construction process, no longer requiring drilling construction, and avoiding detection errors during drilling, saving workload. In an optional embodiment, the end of the insertion section 121 is provided with a pointed cone head, such as an iron conical drill bit, to facilitate insertion into the concrete layer. The entire insertion section 121 can also be set as a cone structure, which makes it easier to insert into the concrete.
[0037] In an optional embodiment, the two ends of the elastic connector 130 are respectively connected to the tubular cavity 112 and the operating section 123. According to the configuration of the above-mentioned support assembly 110 and the measuring rod 120, one end of the elastic connector 130 is connected to the end of the tubular cavity 112 by welding, interference fit connection or other methods, and the other end of the elastic connector 130 is connected to one end of the operating section 123 by welding or other methods. At this time, the middle section 122 is placed in the elastic connector 130. If an elastic part with an internal space and connecting the two ends is used, such as a spring, a disc spring, etc., all or part of the middle section 122 is located in the internal space of the spring. In this way, when the middle section 122 enters the through cavity 110a along with the insertion section 121, the spring always acts between the tubular cavity 112 and the operating section 123.
[0038] Please refer to Figure 2 In an optional embodiment, the measuring rod 120 also includes a joint 124 and an extension rod 125. The joint 124 is connected to the end of the operating section 123. The extension rod 125 is connected to the operating section 123 through the joint 124. The extension rod 125 is used as an extended portion of the operating section 123 for measuring concrete that is far away or deep. For example, when performing detection underground, the extension rod 125 uses a hollow tube, such as a hollow steel tube, a hollow iron tube, etc. The joint 124 is welded and fixed to the end of the operating section 123, and can also be fixed in other ways. The joint 124 is provided with an external thread, and the end of the extension rod 125 is provided with a thread groove, so that the extension rod 125 can be connected to the end of the operating section 123 by thread matching to form an extended rod-like structure.
[0039] Please refer to Figure 3 and Figure 4In an optional embodiment, the detector 140 is a rangefinder, which is fixed to the measuring rod 120. The rangefinder adopts an existing infrared rangefinder, and other position detection instruments can also be adopted, which can more accurately reflect the concrete thickness value. The rangefinder is an electronic product, which is reusable, environmentally friendly and pollution-free. The rangefinder is fixed to the end of the operating section 123 by screws or hoop rings, and can also be fixed by snap-on method or by setting a slot, and the installation position can be adjusted according to actual needs. In an optional embodiment, the detector 140 can also be a non-electronic product. The detector 140 is a scale bar with scales, at least at the end position close to the operating section 123, and part of the scale bar is placed in the measuring rod 120. For example, the operating section 123 is provided with an elongated hole connecting the two ends, and the scale bar is placed in the hole and can slide relative to the operating section 123. One end of the scale bar extends out of the operating section 123 and is connected to the end of the tubular cavity 112 of the support assembly 110, such as embedding the end of the scale bar into the tubular cavity. The end face of the body 112, the other end of the scale bar is located at a position extending from the end of the measuring rod 120, that is, this end of the scale bar extends from the hole of the operating section 123, and the extended length is at least greater than the length that the insertion section 121 can extend out of the support assembly 110. In the initial position, the end of the operating section 123 corresponds to the zero scale of the scale bar. When the operating section 123 moves to the left in the figure, the scale bar remains stationary. When data needs to be read, the scale value on the scale bar corresponding to the end of the operating section 123 is directly read.
[0040] The tool 100 of the present application first determines the number of extension rods 125 according to the monitoring position. Taking the electronic detection instrument as an example, the downhole measurement process is divided into the following 6 steps:
[0041] 1. Install and fix the detector 140 on the operating section 123, check the measuring rod 120, and ensure that the measuring rod 120 can smoothly extend out of the through cavity 110a;
[0042] 2. Place the support assembly 110 at the inspection point of the concrete layer, press the detection button of the detector 140 to measure, and then the detector 140 senses the relative position of the support assembly 110 and outputs the parameters, and reads the measurement parameter 1 and records it;
[0043] 3. Apply force to the measuring rod 120 so that the end of the measuring rod 120, such as the insertion section 121, is inserted into the shotcrete until it contacts the rock formation, and then press the detection button of the detector 140 to perform a secondary measurement. At this time, the detector 140 senses the relative position of the support assembly 110 and outputs the parameters, and reads and records the measurement parameter 2;
[0044] 4. Subtract the recorded parameters 1 and 2 to obtain parameter 3, which is the thickness of the shotcrete.
[0045] 5. Compare the measured parameter 3 with the designed thickness of the shotcrete to determine whether additional spraying is required. Finally, the detector 140 can be removed, and the extension rod 125 can be disassembled, stored, and easily transferred.
