Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a building repair and correction device. Background Technology

[0002] Due to their age, the brick walls or stone tablets of ancient buildings may shift or tilt. In order to protect cultural relics, tilted walls are generally not demolished, but rather repaired and adjusted to correct their tilt.

[0003] The main body of the monument is mostly made of bricks, and bricks themselves are brittle materials with poor earthquake resistance. They are easily broken when subjected to external impacts. Even stone monuments have reduced overall strength due to long-term exposure to wind and sun.

[0004] The monument's structure has text and patterns engraved on its front and back sides. The important parts are the front and back sides with text and patterns, while the middle part can be replaced with other materials to improve rigidity.

[0005] When the middle part of the monument is hollowed out, the front and back sides of the monument are prone to breakage during construction because they lose the middle support. Summary of the Invention

[0006] The purpose of this invention is to provide a building repair and correction device to solve the problem mentioned in the background art that the front and back sides of a building are prone to breakage during construction due to the loss of intermediate support.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A building repair and correction device, comprising:

[0009] The support assembly has two sets, one for supporting the left and one for supporting the left and right side walls of the building.

[0010] The rejection assembly includes a crossbeam and a lifting assembly for driving the crossbeam to rise and fall. A grinding assembly is installed at the bottom of the crossbeam and a clamping assembly is installed at the top of the crossbeam.

[0011] A precast cage, which is clamped and fixed to the top of a beam by a clamping assembly, is adapted to the stripped area of ​​the building.

[0012] Preferably, the support assembly includes a support plate, on which adjusting screws are evenly arranged in an array, and an elastic bag is provided on one side of the support plate. The abutting end of the adjusting screws abuts against the side wall of the building through the elastic bag, and an air nozzle is provided on the elastic bag.

[0013] Preferably, the adjusting screw abutting end is provided with a rubber component.

[0015] Preferably, the polishing assembly includes a rotating shaft rotatably connected to the crossbeam by a first motor, and at least two sets of parallel chain and sprocket assemblies. The sprockets in the chain and sprocket assemblies are installed at any position on the rotating shaft, and scrapers are uniformly arranged on the outer wall of the chain in the chain and sprocket assembly, with the scrapers on adjacent sets of chains being staggered.

[0016] Preferably, the scraper has a crescent-shaped structure on both sides.

[0017] Preferably, the rotating shaft is equipped with a spacing adjustment mechanism for adjusting the spacing between two adjacent sets of sprockets.

[0018] Preferably, the spacing adjustment mechanism includes a second motor and a threaded rod. The threaded rod is rotatably connected to the inner cavity of the rotating shaft. The output end of the second motor is connected to one end of the threaded rod. An inner slider is threadedly connected to the outer wall of the threaded rod, and the inner slider is integrated with the sprocket.

[0019] Preferably, the assembly also includes a movable bracket and a fixed bracket. The lifting component is mounted on the movable bracket, one end of the crossbeam is mounted on the output end of the lifting component, and the other end of the crossbeam is detachably and slidably engaged with the fixed bracket.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The support components can adapt to buildings of different shapes, providing support for various parts of the building's front and back surfaces. At the same time, the elastic bags inflate and fit snugly against the building's surface, preventing the remaining front and back surfaces from cracking due to vibrations caused by the grinding device hollowing out the middle of the building.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example:

[0041] like Figure 1-12 As shown:

[0042] like Figure 3 As shown, the support assembly 300 includes a base 1, a support plate 2, a hydraulic cylinder 3, adjusting screws 4, and an elastic bag 5. The elastic bag 5 is made of elastic material and can be elastically deformed. The edge of the elastic bag 5 is fixed to the side wall of the support plate 2, so that the elastic bag 5 and the support plate 2 cooperate to form a sealed space. The elastic bag 5 covers all the adjusting screws 4 on the side wall of the support plate 2. An air nozzle (not shown in the figure) is installed on the elastic bag 5. When in use, the base 1 is first fixed to the ground. The two ends of the hydraulic cylinder 3 are respectively hinged to the base 1 and the support plate 2. The lower end of the support plate 2 is hinged to the base 1. The adjusting screws 4 are threadedly connected to the support plate 2, and a number of adjusting screws 4 are arranged in a rectangular array on the support plate 2. A rubber part 401 is provided at the end of the adjusting screw 4 near the building 100.

[0043] like Figure 4 As shown, the rejection assembly 400 includes a movable support 41, a lifting assembly 42 (which can be a linear motion module or a hydraulic cylinder), a crossbeam 43, a grinding assembly 44, a clamping assembly 45, and a fixed support 46. The two ends of the crossbeam 43 slide vertically and linearly with the movable support 41 and the fixed support 46, respectively. The lifting assembly 42 is mounted on the movable support 41, and the output end of the lifting assembly 42 is connected to the crossbeam 43. The grinding assembly 44 is mounted at the bottom of the crossbeam 43, and two sets of clamping assemblies 45 are mounted at the top of the crossbeam 43.

[0044] like Figure 5-8 As shown, two rotating shafts 443 are rotatably connected to the bottom of the crossbeam 43. One of the rotating shafts 443 is connected to the output end of the first motor 444. A sprocket 445 is installed on the outer wall of the rotating shaft 443 and can slide relative to the axis of the rotating shaft 443. A limiting member 446 is installed on the outer wall of the rotating shaft 443 and can slide relative to the axis of the rotating shaft 443. Then, the limiting member 446 is clamped and fixed at any position on the rotating shaft 443 by a screw assembly. A chain 441 is engaged with the two sets of sprockets 445 for transmission. The sprockets 445 are fixed relative to the rotating shaft 443 by the limiting member 446 on opposite sides.

[0045] like Figure 6 As shown, three chains 441 are parallel to each other, and scrapers 442 are evenly spaced along the transmission trajectory on the outer wall of the chains 441. The scrapers 442 between adjacent chains 441 are staggered. Since the three chains 441 are driven synchronously, interference between the staggered scrapers 442 is avoided. The spacing between the chains 441 can be adjusted to adjust the width of the multiple sets of scrapers 442, thereby adjusting the width of the scraper 442 scraping away the central removal area 200 of the building 100.

[0046] like Figure 7 As shown, the opposing sides of the scraper 442 have a crescent-shaped structure, so that the scraper 442 can scrape away the building 100 when the chain 441 rotates forward and backward. Figure 8 As shown, the width of the scraper 442 along its direction of movement is much greater than the width of the chain 441. For example... Figure 6 As shown, the two sets of scrapers 442 on the two adjacent sets of chains 441 have overlapping parts along their moving direction.

[0047] like Figure 9 As shown, the fixed bracket 46 has a vertical sliding groove 461 on its side wall, and a first guide member 431 is provided at the right end of the crossbeam 43. The first guide member 431 and the vertical sliding groove 461 slide vertically in a straight line. A second slot 462 is provided at the lower part of the vertical sliding groove 461. The shape of the second slot 462 is larger than that of the first guide member 431, so that the first guide member 431 disengages from the second slot 462.

[0048] like Figure 10 As shown, the crossbeam 43 has an "I" shaped structure, and the middle part is narrower, with a width less than the width of the three sets of chains 441. The top wall of the crossbeam 43 has a horizontal sliding groove 432, and the clamping component 45 slides horizontally in a straight line within the horizontal sliding groove 432. The end of the horizontal sliding groove 432 near the fixed bracket 46 has a first slot 4321. The shape of the first slot 4321 is larger than the shape of the clamping component 45, so that the clamping component 45 can be disengaged from the first slot 4321. The clamping component 45 has a conventional structure and will not be described in detail.

[0049] Working principle:

[0050] Two sets of support components 300 are placed on the left and right sides of the building 100 to be repaired. The left and right sides of the building 100 have text / patterns, so the left and right side walls of the building 100 are uneven. Then, the base 1 is fixed to the ground, and the adjusting screw 4 is rotated so that the rubber part 401 at its abutting end abuts against the left / right side of the building 100 through the elastic bag 5. At this time, the left / right side walls of the building 100 are supported by the abutting of the rectangular array of adjusting screws 4.

[0051] The array of adjusting screws 4 abuts against the left / right side walls of building 100 to achieve rigid support. At this time, the surface of building 100 in the space between two adjacent adjusting screws 4 is not supported, and there is a possibility of vibration causing breakage. Therefore, air is injected into the space formed by the elastic bag 5 and the support plate 2 through the air nozzle. The elastic bag 5 can elastically deform and perfectly fit the uneven parts of the left and right side walls of building 100. The elastic bag 5 provides flexible support for the left and right side walls of building 100, avoiding damage to the text and patterns on the surface of the left and right side walls of building 100 caused by vibration.

[0052] The movable bracket 41 is placed on the front wall of the building 100, and the fixed bracket 46 is placed on the rear side of the building 100 and fixed relative to the ground. The first motor 444 drives the rotating shaft 443 to rotate. The rotation of the rotating shaft 443 drives the corresponding chain 441 to rotate cyclically through the sprocket 445. The cyclic rotation of the chain 441 drives the scraper 442 to move cyclically along the trajectory of the chain 441.

[0053] The precast cage 500 (precast steel cage) is placed on top of the crossbeam 43. Two sets of clamping components 45 slide on the transverse sliding groove 432 and abut against the front and rear sides of the precast cage 500 respectively. Then the clamping components 45 are fixed to the crossbeam 43. The two sets of clamping components 45 cooperate to clamp and fix the precast cage 500. At this time, the left and right sides of the precast cage 500 are roughly flush with the left and right edges of the multiple scrapers 442 composed of three chains 441.

[0054] The lifting assembly 42 drives the crossbeam 43 to descend, causing the scraper 442, which moves cyclically along the track direction of the chain 441, to scrape the upper surface of the building 100 from top to bottom. The scraping area 200 in the middle of the building 100 is scraped off by the scraper 442. The width of the middle part of the crossbeam 43 is smaller than the scraping area 200 scraped off by the scraper 442. Therefore, when the lifting assembly 42 drives the crossbeam 43 to descend, the precast cage 500 also follows and inserts into the scraped area 200 in the middle of the building 100.

[0055] After the removal zone 200 in the middle of the building 100 is scraped away, the left and right side walls of the building 100 become isolated islands with relatively thin walls. Therefore, the support component 300 and the prefabricated cage 500 work together to support the left and right side walls of the isolated building 100 on opposite sides.

[0056] After the removal area 200 in the middle of the building 100 is completely scraped away, the first guide 431 at the right end of the crossbeam 43 is lowered vertically into the second slot 462. Then, the clamping assembly 45 near the fixed bracket 46 is released and this clamping assembly 45 is slid into the first slot 4321 to disengage from the crossbeam 43.

[0057] Then, the movable bracket 41 is dragged horizontally to move away from the fixed bracket 46, so that the first guide member 431 of the crossbeam 43 passes through the second slot 462 and disengages from the vertical slide groove 461, thereby realizing the separation of the crossbeam 43 and the fixed bracket 46, and the crossbeam 43 moves horizontally and is pulled out from below the precast cage 500.

[0058] Then, the relative position of the precast cage 500 in the removal area 200 of the building 100 is manually adjusted, and then concrete is filled into the removal area 200. The precast cage 500 and the concrete work together to form reinforced concrete to replace the material in the middle of the building 100.

[0059] Example 2: An improvement based on Example 1;

[0060] like Figure 11 A threaded rod 448 is coaxially rotatably connected to the inner cavity of the rotating shaft 443. A second motor 447 is installed at one end of the rotating shaft 443. The output end of the second motor 447 is connected to one end of the threaded rod 448. Three sets of inner sliders 446 are slidably connected to the inner cavity of the rotating shaft 443 along its axial direction. Three sets of sprockets 445 are fixedly connected to the three sets of inner sliders 446 in a one-to-one correspondence.

[0061] The inner slider 446 on the left is connected to the threaded rod 448 with a left-hand thread; the inner slider 446 in the middle is connected to the threaded rod 448 with a rotational connection in place; and the inner slider 446 on the right is connected to the threaded rod 448 with a right-hand thread.

[0062] As the crossbeam 43 descends, the second motor 447 rotates forward and backward a set number of times according to the set program. When the second motor 447 rotates forward, the inner slider 446 on the left moves away from the middle inner slider, and the inner slider 446 on the right moves away from the middle inner slider 446, so that the distance between each pair of adjacent inner sliders 446 is the same. The middle inner slider 446 is relatively fixed relative to the threaded rod 448 along the axis of the threaded rod 448, thereby expanding the distance between the two outermost chains 441.

[0063] When the second motor 447 reverses, the inner slider 446 on the left moves to the right closer to the inner slider in the middle, and the inner slider 446 on the right moves to the left closer to the inner slider in the middle, thereby reducing the distance between the two outermost chains 441. It should be noted that the width of the prefabricated cage 500 is the same as the minimum width of the rejection area 200.

[0064] This allows the distance between the two outermost chains 441 to be adjusted by the spacing adjustment mechanism during the grinding process of the grinding component 44 descending to grind the building 100. This results in different widths of the scraped material being removed from the removal area 200 at different horizontal heights, creating an uneven inner wall on the removal area 200. Figure 12 As shown, this facilitates a stronger connection with the building 100 during subsequent concrete pouring.

[0065] The spacing adjustment mechanism has two functions. First, the operator can adjust the distance between two adjacent chains 441 through the controller, thereby adjusting the width of the rejection area 200 of the building 100. Second, during the process of the lifting component 42 driving the crossbeam 43 to descend, the distance between the two outermost chains 441 is automatically adjusted back and forth through the program.
