Description

Technical Field

[0001] The utility model relates to the technical field of concrete crack monitoring, in particular to a monitoring device for the cracking and expansion of concrete surface cracks. Background Art

[0002] Concrete is concrete, and the cracking of the concrete surface is one of the core problems of current construction engineering quality. The cracking of the concrete surface requires the monitoring of cracks.

[0003] For example, a monitoring device for the cracking and expansion of concrete surface cracks disclosed in Chinese Patent Application No. CN202222098580.5, the specific content of which is as follows: When detecting concrete, first fix the detection tube at the side end of the concrete body through the connection assembly. At the same time, after fixation, the sealing mechanism is in a contracted state. Then pull the pressure application mechanism, and then add water to the inner cavity of the detection tube through the water inlet pipe. When a certain amount of water is added, close the water inlet pipe and then release the pressure application mechanism. The pressure application mechanism applies pressure to the side end of the concrete body through water. At the same time, the alarm mechanism is in a disconnected state at this time. When the surface of the concrete body cracks, the water in the detection tube will gradually flow away through the cracks. At this time, the pressure application mechanism will gradually move to the left, and finally the alarm mechanism will be in an open state, and the alarm mechanism will send an alarm to the outside. However, it has the following technical problems:

[0004] When pouring water into the detection tube through the water inlet pipe, the water easily penetrates into the cracks of the concrete through the middle of the sealing ring, causing water to enter the internal gaps of the concrete before the pressure application mechanism detects, thus affecting the detection results of the concrete cracks. Content of the Utility Model

[0005] In order to solve the problem that water enters the gap and affects the detection structure before the pressure application mechanism detects as mentioned in the above background art, the utility model provides the following technical solutions:

[0009] The first detection structure includes a detection cylinder, a partition is installed inside the detection cylinder, a second water outlet hole for water to flow through is opened in the middle of the partition, and a sealing disc for blocking the second water outlet hole is installed in the inner cavity of the detection cylinder.

[0014] Further, the adjusting device includes a pressure - applying component, an adjusting component for limiting the pressure - applying component is sleeved at the right end of the pressure - applying component, and a limiting component for limiting the adjusting component is sleeved outside the adjusting component.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] When the detection structure two does not push the water, the spring one pushes the sealing disc, so that the sealing disc seals the gasket, avoiding water leakage when the water inlet pipe conveys water to the inner cavity of the detection cylinder, which may cause inaccurate detection results. When detecting cracks, pull the piston to the left until it is to the left of the scale plate, and align the zero position on the left side of the scale plate with the outer wall on the right side of the detection cylinder.

When it is difficult to push the handle, the capacity of the crack can be calculated according to the moving distance indicated by the scale plate on the outer wall of the detection cylinder.

Detailed implementation manners

[0034] The preferred specific implementation manners for implementing the present utility model are described in detail below, and a clear and complete description is made in combination with the accompanying drawings.

[0035] Please refer to Figures 1-7 , the present utility model provides a monitoring device for the cracking and expansion of concrete surface cracks.

[0036] On the left side of the first detection structure 001, there is a concrete structure 10 for limiting the first detection structure 001. In the middle of the concrete structure 10, there is a crack 11. The first detection structure 001 cooperates with the second detection structure 002 to check the size of the crack 11, facilitating the preparation of an appropriate amount of repair solution for repair and avoiding the waste caused by excessive preparation of the repair solution.

[0037] The first detection structure 001 includes a detection cylinder 100. On the left end of the detection cylinder 100, there is a first water outlet hole 110 for the circulation of water. Inside the detection cylinder 100, there is a partition plate 120 fixedly installed. In the middle of the partition plate 120, there is a second water outlet hole 121 for the circulation of water. On the left side of the partition plate 120, there is a sealing gasket 122 fixedly installed. Inside the cavity of the detection cylinder 100, there is a sealing disk 130 for blocking the second water outlet hole 121, and the sealing disk 130 is on the left side of the sealing gasket 122. On the left side of the sealing disk 130, there is a first spring 140 for pushing the sealing disk 130. When the second detection structure 002 does not push the water, the first spring 140 pushes the sealing disk 130 to block the sealing gasket 122, avoiding the water flowing out when the water inlet pipe 160 transports water into the cavity of the detection cylinder 100 and causing inaccurate detection results.

[0038] On the side of the detection cylinder 100, there are a plurality of limiting plates 150 fixedly installed. In the middle of the limiting plates 150, there is a first bolt 151 for limiting the detection cylinder 100. The detection cylinder 100 is fixed on one side of the concrete structure 10 through the first bolt 151, and the crack 11 is on the side of the first water outlet hole 110.

[0039] At the upper middle part of the detection cylinder 100, a water inlet pipe 160 is installed. A switch 161 is installed in the middle of the water inlet pipe 160. By opening the switch 161, water flows into the inner cavity of the detection cylinder 100, and the water is between the partition plate 120 and the piston 200. An alarm 170 is fixedly installed at the upper right end of the detection cylinder 100. A control switch 171 is arranged at the right end of the alarm 170. By pressing the control switch 171 with the extrusion block 312, the alarm 170 gives an alarm.

[0040] In the middle of the detection structure one 001, a detection structure two 002 is installed for cooperating with the detection structure one 001 to detect the crack 11. The detection structure two 002 includes a piston 200 for pushing water. A piston rod 210 is fixedly installed at the right end of the piston 200. A handle 211 for cooperating with the piston rod 210 to push and pull the piston 200 is fixedly installed at the right end of the piston rod 210. A second spring 220 for pushing the piston 200 is sleeved on the left end of the piston rod 210, and the second spring 220 is in the right inner cavity of the detection cylinder 100. The right side of the second spring 220 abuts against the side wall of the right inner cavity of the detection cylinder 100. A scale plate 230 for displaying the capacity size of the crack 11 is installed in the middle of the piston rod 210. A cavity for placing the scale plate 230 is opened in the middle of the piston rod 210. In the middle of the piston rod 210, by adding the diameter of the detection cylinder 100 and the distance that the piston 200 moves to the left in the detection cylinder 100, the capacity size of the crack 11 can be calculated.

[0041] When detecting the crack 11, the piston 200 is pulled to the left until the left side of the scale plate 230 aligns with the right outer wall of the detection cylinder 100 at the zero position on the left side. Water is filled into the inner cavity of the detection cylinder 100 through the water inlet pipe 160. Then the switch 161 is closed, and the handle 211 is released. The second spring 220 drives the piston 200 to move to the left, pushing the water. The pressure drives the sealing disc 130 to squeeze the first spring 140, so that the water flows through the gap between the sealing disc 130 and the inner wall of the detection cylinder 100 to the water outlet one 110, and finally flows into the inside of the crack 11. At the same time, the piston 200 can be pushed to the left through the handle 211 to accelerate the movement of water into the crack 11. Finally, when the crack 11 is filled and it is difficult to push the handle 211, the capacity size of the crack 11 can be calculated according to the moving distance indicated by the detection cylinder 100's outer wall pointing to the scale plate 230.

[0042] An adjusting device 300 is installed at one end of the piston 200 for cooperating with the piston 200 to detect the capacity of the crack 11. The adjusting device 300 includes a pressure component 310. The pressure component 310 includes a push plate 311. The left end of the push plate 311 is fixedly installed with an extrusion block 312 for pressing the control switch 171. A sliding rod 313 is installed at the fixed right end of the push plate 311. A limiting hole 314 is opened in the middle of the right side of the sliding rod 313, and the long rod 324 is extended and retracted in the hole cavity of the limiting hole 314 to limit the pressure component 310. A slider 315 is fixedly installed on the upper right end of the sliding rod 313 for cooperating with the adjusting component 320 to limit the pressure component 310. The pressure component 310, the adjusting component 320 and the alarm 170 cooperate to judge the capacity of the crack 11 to determine whether the crack 11 needs to be repaired.

[0043] The right end of the pressure component 310 is sleeved with an adjustment component 320 for limiting the pressure component 310, and the adjustment component 320 includes a limit block 321, and a plurality of plug holes 322 are provided at the upper end of the limit block 321, and a limit hole 2 323 is provided at the lower end of the adjustment component 320 for the limit hole 1 314 to be extended and retracted, and a long rod 324 is fixedly installed at the right end of the cavity of the limit hole 2 323, and the long rod 324 is extended and retracted in the cavity of the limit hole 1 314, and a spring 325 for pushing the sliding rod 313 is installed at the right end of the long rod 324, and a sliding groove 326 for the sliding block 315 to slide is provided at the upper right end of the groove cavity of the limit hole 2 323.

[0044] The operator can determine the capacity required to repair the crack 11 by adjusting the distance between the squeezing block 312 and the alarm 170. When the piston 200 drives the adjustment device 300 to approach the control switch 171, the squeezing block 312 does not collide with the alarm 170, indicating that the crack 11 does not need to be repaired. When the squeezing block 312 presses the control switch 171, the alarm 170 sounds an alarm, indicating that the crack 11 needs to be repaired. The right side of the slide bar 313 squeezes the spring 325, and the slide bar 313 slides in the groove of the second limit hole 323, so as to prevent the squeezing block 312 from over-squeezing the control switch 171 and causing damage to the control switch 171.

[0045] The outer sleeve of the adjustment component 320 is provided with a limit component 330 for limiting the adjustment component 320. The limit component 330 includes a limit cylinder 331. A bolt 2 332 is installed on the upper end of the limit cylinder 331. A threaded sleeve is installed on the upper end of the limit cylinder 331 so that when the bolt 2 332 is rotated, the plug block 333 gradually moves toward the cavity of the socket 322. The lower end of the bolt 2 332 is fixedly installed with an plug block 333 for cooperating with the socket 322 to limit the limit block 321.

[0046] When the capacity of the crack 11 is relatively large, the adjusting assembly 320 can be moved to the right side of the middle cavity of the limiting cylinder 331, so that the insertion block 333 is inserted into the cavity of the leftmost jack 322 of the limiting block 321 to increase the lateral detection length and facilitate the detection of the crack 11 with a relatively large capacity.

[0047] Based on the above content and the drawings, those skilled in the art can understand and implement the present utility model. In addition, any non-creative modifications made to the present utility model by those skilled in the art without creative efforts still fall within the protection scope of the present utility model.
