Technical Field
[0001] The utility model belongs to the technical field of building engineering detection, and particularly relates to a simple crack measuring tool for concrete components. Background Art
[0002] The occurrence of cracks in concrete components is a common problem, which may be caused by various factors, including design, construction, materials, and external environmental conditions, etc. Correctly judging and analyzing the causes of concrete cracks is the most effective way to effectively control and reduce the generation of concrete cracks. When measuring the cracks in concrete components, special crack measuring equipment is usually used to measure the crack width of concrete components.
[0003] For example, the patent with the publication number CN206919840U discloses a device for measuring the crack width of concrete components, including a base and an infrared equipment ranging cabinet. An infrared ranging head is connected below the infrared equipment ranging cabinet. The infrared equipment ranging cabinet is driven to slide along the width direction of the base through a transverse sliding mechanism. Longitudinal sliding mechanisms are respectively arranged on both sides of the base along the width direction and are connected with the transverse sliding mechanism to drive the transverse sliding mechanism to move back and forth along the length direction of the base. It has the advantages of being able to complete the measurement of the width of fine cracks and being able to automatically patrol along the crack path. However, the crack measuring device in the above technology still has the following problems: Due to the professionalism of the infrared ranging equipment, when cracks in concrete components are found, the use of the infrared ranging equipment requires a certain professional use foundation, which has certain requirements for the knowledge reserve of the users, bringing certain inconvenience to the measurement of cracks in concrete components. In addition, the crack conditions of concrete components during construction are diverse. Some cracks are relatively large and require the use of special measuring instruments for measurement, and then the reasons for crack formation are analyzed based on the measured crack depth and width, and the process is adjusted in a timely manner. While some cracks are relatively small, generally with a width within 1 mm and a depth of 10 mm to 50 mm. When using a special measuring device for measurement, the process is relatively cumbersome and requires a certain knowledge reserve. At this time, some simple measuring tools are more popular and can improve work efficiency more. Summary of the Invention
[0004] Aiming at the above problems existing in the prior art, the utility model provides a simple crack measuring tool for concrete components, which does not require professional knowledge reserve, is easy to operate, and is convenient to carry.
[0005] The purpose of the utility model is achieved in the following way:

[0009] The scale lines are arranged in a ring shape.
[0010] Compared with the prior art, the simple crack measurement tool for concrete components disclosed by the present utility model has a simple structure and is convenient to carry. According to the size of the crack in the concrete component, a width measurement piece with an appropriate thickness is selected and inserted into the crack of the concrete component, and then the width of the crack can be measured. By inserting the depth measurement needle into the crack, the depth of the crack can be directly read. The operation is simple, and no professional knowledge reserve is required, which is suitable for most people to use. Description of the Drawings

[0012] Figure 2 is a schematic structural diagram of the width measurement piece of the present utility model.
[0013] Figure 3 is a schematic structural diagram of the depth measurement needle of the present utility model.
[0014] In the figure: 3, connecting ring; 4, width measurement piece, 401, connecting hole, 402, breaking groove; 5, hanging ring; 6, depth measurement needle; 7, thickness label; 8, handheld block; 9, protective shell; 10, scale line. Detailed Embodiment
[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0016] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, a simple crack measurement tool for concrete components includes a connecting ring 3. At least one width measurement piece 4 and a depth measurement needle 6 are arranged on the connecting ring 3. The width measurement piece 4 is slidably connected to the connecting ring 3 through a connecting hole 41 opened at the end. Thickness labels 7 are arranged on one or both side walls of the width measurement piece 4 near one end of the connecting hole 401. At least one breaking groove 402 is arranged on the width measurement piece 4 along the length direction. The thicknesses of multiple width measurement pieces 4 are arranged in a uniformly decreasing manner; the depth measurement needle 6 is slidably connected to the connecting ring 3 through a lifting ring 5 arranged at the end. The depth measurement needle 6 is sleeved in a protective shell 9, and scale lines 10 are marked on the surface of the depth measurement needle 6 along its length.
[0017] When the simple crack measurement tool for concrete components of the present utility model is in use, according to the observed crack width of the concrete component, a suitable width measurement piece 4 is selected from multiple width measurement pieces 4 and inserted into the crack. The thickness of the width measurement piece 4 corresponds to the width of the crack of the concrete component. Through the insertion test, the width measurement piece 4 that fits the crack of the concrete component best is found. The reading of the thickness label 7 of the current width measurement piece 4 is the crack width of the concrete component. When measuring the depth of the crack, the depth measurement needle 6 is inserted into the crack. Scale lines 10 are marked on the surface of the depth measurement needle 6 along its length. The zero point of the scale line is at the free end of the depth measurement needle 6 (the other end away from the lifting ring). The scale line corresponding to the depth at which the depth measurement needle 6 is inserted into the crack is the depth of the crack, and the depth measurement of the road crack is completed. After the depth measurement is completed, the depth measurement needle 6 is placed in the protective shell 9. On the one hand, it can prevent the depth measurement needle 6 from being damaged. On the other hand, since the depth measurement needle is relatively thin and easy to prick people, placing it in the protective shell 9 can improve the safety factor.
[0018] Thickness labels 7 are arranged on one or both side walls of each width measurement piece 4 near one end of the connecting hole 401, which can facilitate the user to directly obtain the measured width of the crack by observing the thickness label 7 when measuring the crack thickness, making it more convenient to use; among them, the thickness label 7 can be printed by means of engraving, pressing, etc. When manufacturing the width measurement piece 4, the thickness label 7 is integrally manufactured with the width measurement piece 4.
[0019] Since the width measurement piece 4 needs to be inserted into the crack of the concrete component during each measurement, the inserted part of the measurement piece 4 is easily worn, reducing the measurement accuracy. By setting the breaking groove 402, the worn width measurement piece 4 can be broken off, and then the non-worn width measurement piece 4 at the rear end can be used for insertion measurement, ensuring the measurement accuracy and at the same time reducing the replacement frequency of the width measurement piece 4, making the use efficiency of the width measurement piece 4 higher.
[0020] Further preferred solution, the breaking groove 402 is of a triangular structure, and the deeper end is located in the direction away from the connection hole 401. Setting the breaking groove 402 as a triangle makes it easier to break the width measuring piece 4. At the same time, the end of the width measuring piece 4 to be used after breaking is thinner, making it easier to insert into the crack of the concrete member, and it is more convenient to use.
[0021] A hand-held block 8 is arranged between the lifting ring 5 and the depth measuring needle 6. By pinching the hand-held block 8, it is easier to insert the depth measuring needle 6 into the crack for depth measurement. Threads are provided on the outer wall of the hand-held block 8 near one end of the depth measuring needle 6, and the hand-held block 8 is threadedly connected to the protective shell 9. Using the threaded connection between the protective shell 9 and the hand-held block 8, when the depth measuring needle 6 is not in use, the protective shell 9 and the hand-held block 8 are tightened, and the depth measuring needle 6 is protected inside, protecting the depth measuring needle 6 from being damaged by collision or bent by force, and improving safety.
[0022] The scale lines 10 are arranged in a ring shape. The scale lines 10 are provided on the measuring needle 6, which is convenient for accurately and timely obtaining the crack depth value when measuring the crack depth. The scale lines 10 are set in a ring shape, which is convenient for reading the crack depth inserted by the depth measuring needle 6 from any direction.
[0023] The simple concrete member crack measuring tool disclosed by the present utility model has a simple structure. According to the size of the crack of the concrete member, a width measuring piece with a suitable thickness is selected and inserted into the crack of the concrete member, and then the width of the crack can be measured. By inserting the depth measuring needle into the crack, the depth of the crack can be directly read. The operation is simple, and no professional knowledge reserve is required, which is suitable for most people to use.
[0024] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those skilled in the art, without departing from the overall concept of the present utility model, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present utility model.
