Description

Technical Field

[0001] The utility model relates to the technical field of building wall detection, in particular to a building deformation detection device. Background Art

[0002] During the construction process, it is necessary to detect the horizontality and verticality of the building's walls and beams. To determine whether the wall is deformed, a building deformation detection device is needed, such as Figure 8 As shown, Chinese patent CN116293330A discloses a building wall verticality detection device, which includes a lifting assembly installed on the upper surface of a base, and rollers are rotatably connected to the four corners of the lower surface of the base, the top of the lifting assembly is fixedly connected to a fixed seat, and the side of the fixed seat is fixedly connected to a horizontal telescopic assembly, the telescopic end of the horizontal telescopic assembly is rotatably connected to a detection box on a vertical plane, a circular angle ruler is fixedly installed inside the detection box, and a pendulum is rotatably connected to the center of the circular angle ruler, and the pendulum always points vertically to the ground under the action of its own weight, the end of the detection box away from the horizontal telescopic assembly is fixedly connected to a vertical base plate, the four corners of the vertical base plate are horizontally slidably connected to positioning rods, and the inner side of the vertical base plate is fixedly connected to a driving assembly that is transmission-connected to the positioning rod.

[0003] However, there are some drawbacks in the use of existing building deformation detection devices, such as:

[0004] The detection mechanism is set on a mobile base, and the mobile device is driven by the mobile base to move inside the building to detect whether the building wall is deformed. In actual use, the floor inside the building is uneven after the initial pouring. Since the mobile base is on the uneven ground, a large error is caused in the wall deformation detection. In addition, before the building is delivered, there are often a lot of debris inside the construction site. The mobile base is used to move the equipment and complete the detection in conjunction with the detection mechanism, which makes it inconvenient to store and move the equipment, which ultimately results in low detection efficiency. For this reason, we propose a building deformation detection device. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a building deformation detection device to solve the problems of low detection efficiency and large detection error in existing building deformation detection devices.

[0006] Based on the above purpose, the utility model provides a building deformation detection device, comprising a first rod, the first rod being hollow inside, a second rod being movably provided on the upper end of the first rod, a measuring assembly being provided on the ends of the first rod and the second rod, an angle recognition assembly being provided on the side wall of the end of the first rod, a limit assembly being provided on the upper end of the first rod, and the limit assembly being adapted to the second rod;

[0007] The measuring assembly has two mounting plates, which are respectively mounted on the lower end of the first rod and the upper end of the second rod, and the mounting plates are provided with infrared distance sensors and tapered blocks on the sides of the mounting plates;

[0008] The angle identification component includes a connecting rod arranged on the side wall of the upper end of the first rod, the end of the connecting rod is movably connected to a connecting column, the lower end of the connecting column is connected to a shell, a rotating shaft is provided in the middle of the shell, a rotating circle is sleeved on the rotating shaft, a pointer is connected to the upper end of the rotating circle, a counterweight is connected to the lower end of the rotating circle, a first electrode strip is embedded in the upper end of the rotating shaft, a second electrode strip is provided inside the rotating circle, and the first electrode strip and the second electrode strip are adapted to each other.

[0009] Furthermore, the side walls of the two mounting plate ends are aligned, and the distances between the two ends of the infrared distance sensors and the corresponding side walls of the mounting plate ends are the same.

[0010] Furthermore, an angle disc is provided at the upper end of the shell, the angle disc cooperates with the pointer, and a transparent glass plate is provided on the shell.

[0011] Furthermore, when the pointer and the counterweight are vertically downward, the first electrode strip and the second electrode strip are in contact, and the two infrared distance sensors measure a set of data.

[0012] Furthermore, movable grooves are relatively opened on the inner walls at both ends of the first rod, and the limiting assembly includes two threaded tubes connected through the outer walls of the two movable grooves, the threads inside the two threaded tubes are in opposite directions, and the two threaded tubes are threadedly connected with bolts, and the ends of the bolts are sleeved with limit blocks.

[0013] Furthermore, grooves distributed at equal intervals are formed at the end of the limit block, the limit block slides transversely inside the movable groove, and the side walls of the limit block are in contact with the side walls of the second rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the utility model, two conical blocks on the sides of the two mounting plates are pressed against two wall detection points. If the wall is deformed and tilted, the counterweight block will be vertically downward under the action of the gravity of the counterweight block, causing the rotating circle to rotate around the rotating axis, thereby causing the pointer to deflect relative to the first rod, and then the display is read, and finally the deformation angle of the wall is judged; the wall inclination is judged by the pointer, and then the first rod is fine-tuned again so that one of the conical blocks is pressed against a detection point on the wall, and then the first rod is slightly adjusted so that the counterweight block is vertically downward, and the pointer is located at the middle of the angle disk. At this time, the first rod is in the vertical direction, and the first electrode strip and the second electrode strip are in contact. The two infrared distance sensors are energized and measure a set of data. The difference in the inclination distance of the two detection points on the wall is judged by the data difference, so that the utility model can not only measure the inclination angle of the deformed wall, but also measure the distance difference between the two detection points on the wall in the horizontal direction, making the measurement more convenient and the measurement result more accurate.

[0028] A building deformation detection device includes a first rod 1, the first rod 1 is hollow inside, a second rod 2 is movably provided at the upper end of the first rod 1, a measuring component 3 is provided at the end of each of the first rod 1 and the second rod 2, an angle recognition component 4 is provided on the side wall of the end of the first rod 1, and a limit component 5 is provided at the upper end of the first rod 1, and the limit component 5 and the second rod 2 are adapted to each other;

[0029] In actual use, the second rod 2 can be extended and retracted up and down inside the first rod 1, making it more convenient to store and reducing space. At the same time, in actual use, the length and position of the second rod 2 inside the first rod 1 can be automatically adjusted according to the distance between the two detection points that need to be detected.

[0030] The measuring component 3 has two mounting plates 301, which are mounted on the lower end of the first rod 1 and the upper end of the second rod 2 respectively. The mounting plates 301 are provided with infrared distance sensors 302, and the sides of the mounting plates 301 are provided with tapered blocks 303;

[0031] In actual use, when the first rod 1 and the second rod 2 are parallel to the wall or the pillar surface, the two infrared distance sensors 302 measure the distances from the two detection points, and by determining whether the two distances are the same, it is determined whether the detection wall is parallel;

[0032] The angle recognition component 4 includes a connecting rod 401 arranged on the side wall of the upper end of the first rod 1, and the end of the connecting rod 401 is movably connected to a connecting column 402, and the lower end of the connecting column 402 is connected to a shell 403. A rotating shaft 404 is provided in the middle of the shell 403, and a rotating ring 405 is sleeved on the rotating shaft 404. The upper end of the rotating ring 405 is connected to a pointer 406, and the lower end of the rotating ring 405 is connected to a counterweight block 407. A first electrode strip 409 is embedded in the upper end of the rotating shaft 404, and a second electrode strip 410 is provided inside the rotating ring 405. The first electrode strip 409 and the second electrode strip 410 are adapted to each other.

[0033] In actual use, the conical blocks 303 on the sides of the two mounting plates 301 are pressed against the two detection points on the wall. If the wall is deformed and tilted, the counterweight 407 will be vertically downward under the action of gravity, causing the rotating ring 405 to rotate around the rotating shaft 404, thereby causing the pointer 406 to deflect relative to the first rod 1. The displayed number is then read and the deformation angle of the wall is finally determined.

[0034] If the wall is tilted as determined by the pointer 406, the first rod 1 is fine-tuned again so that one of the tapered blocks 303 is against a detection point on the wall, and then the first rod 1 is slightly adjusted so that the counterweight 407 is vertically downward and the pointer 406 is located at the middle of the angle disk 408. At this time, the first rod 1 is in the vertical direction, the first electrode strip 409 and the second electrode strip 410 are in contact, the two infrared distance sensors 302 are energized, and a set of data is measured. The difference in the tilt distance between the two detection points on the wall is determined by the data difference, so that the utility model can not only measure the tilt angle of the deformed wall, but also measure the distance difference between the two detection points on the wall in the horizontal direction, making the measurement more convenient and the measurement result more accurate.

[0035] Furthermore, the side walls of the two mounting plates 301 are aligned, and the distances between the ends of the two infrared distance sensors 302 and the corresponding side walls of the mounting plates 301 are the same, so that when the wall surface is not deformed or tilted, the distances measured by the two infrared distance sensors 302 are the same, thereby ensuring measurement accuracy.

[0036] Furthermore, an angle disc 408 is provided at the upper end of the housing 403 , and the angle disc 408 cooperates with the pointer 406 . A transparent glass plate is provided on the housing 403 .

[0037] In actual use, the index of the pointer 406 is read through the angle plate 408. At the same time, in the utility model, the end of the connecting rod 401 is movably connected to the connecting column 402, and the connecting column 402 can rotate 90 degrees at the end of the connecting rod 401. The connection between the connecting rod 401 and the connecting column 402 is a damping movable connection. In actual use, the connecting column 402 is rotated so as to rotate 90 degrees relative to the connecting rod 401, so that the connecting column 402 and the housing 403 are perpendicular to the first rod 1, so that the first rod 1 and the second rod 2 are placed horizontally. Figure 7 As shown, the same detection method is used to detect whether the beams and the roof are deformed, which makes the utility model have a wide range of applications and diversified measurement scenarios.

[0038] Furthermore, movable grooves are formed on the inner walls at both ends of the first rod 1. The limiting assembly 5 includes two threaded tubes 501 that are connected to the outer walls of the two movable grooves. The threads inside the two threaded tubes 501 are in opposite directions. Bolts 502 are threadedly connected to the inner surfaces of the two threaded tubes 501. The ends of the bolts 502 are sleeved with limit blocks 503. The ends of the limit blocks 503 are formed with grooves distributed at equal intervals. The limit blocks 503 slide horizontally inside the movable grooves, and the side walls of the limit blocks 503 are in contact with the side walls of the second rod 2.

[0039] In actual use, after adjusting the position of the second rod 2, both hands are used to twist the bolts 502 at the same time. Since the threads inside the two threaded tubes 501 are in opposite directions, the two bolts 502 are simultaneously moved closer to the middle, so that the side walls of the limit block 503 are tightly fitted with the side walls of the second rod 2, completing the limiting of the second rod 2. In the present utility model, by squeezing and limiting the two sides of the second rod 2 at the same time, the central axis of the second rod 2 is always aligned with the central axis of the first rod 1, avoiding the detection error caused by the tilt of the second rod 2 and improving the detection accuracy.

[0040] To sum up, in actual use, first, the second rod 2 can be extended and retracted up and down inside the first rod 1, and the length position of the second rod 2 inside the first rod 1 can be independently adjusted according to the distance between the two detection points that need to be detected. After adjusting the position of the second rod 2, both hands simultaneously twist the bolt 502. Since the threads inside the two threaded tubes 501 are in opposite directions, the two bolts 502 are simultaneously moved closer to the middle, so that the side walls of the limit block 503 are tightly fitted with the side walls of the second rod 2, completing the limitation of the second rod 2; the conical blocks 303 on the sides of the two mounting plates 301 are pressed against the two wall detection points. If the wall is deformed and tilted, under the action of the gravity of the counterweight block 407, the counterweight block 407 is vertically downward, causing the rotating circle 405 to rotate around the rotating shaft 404, thereby causing the pointer 406 to deflect relative to the first rod 1, and then the displayed number is read, and finally the deformation angle of the wall is judged;

[0041] If the wall is tilted as determined by the pointer 406, the first rod 1 is fine-tuned again so that one of the tapered blocks 303 is against a detection point on the wall, and then the first rod 1 is slightly adjusted so that the counterweight 407 is vertically downward and the pointer 406 is located at the middle of the angle disk 408. At this time, the first rod 1 is in the vertical direction, the first electrode strip 409 and the second electrode strip 410 are in contact, the two infrared distance sensors 302 are energized, and a set of data is measured. The tilt distance difference between the two detection points on the wall is determined by the data difference, so that the utility model can not only measure the tilt angle of the deformed wall, but also measure the distance difference between the two detection points on the wall in the horizontal direction.
