Description

Technical Field

[0001] This application relates to the field of wall crack repair technology, and in particular to a wall crack repair device for civil engineering construction. Background Technology

[0002] Civil engineering construction, also known as civil engineering construction, encompasses the construction of buildings, structures, and engineering works in various categories, including above-ground, underground, land, water, and underwater, such as houses, roads, railways, airports, bridges, water conservancy, ports, tunnels, water supply and drainage, and protection. Due to the influence of construction technology, construction materials, and some external factors, building walls are prone to cracks. If these cracks are not repaired in time, the cracked area can easily increase, leading to large-scale wall collapse and serious damage to the wall structure.

[0003] For example, Chinese Patent Publication No. CN222253269U describes a wall crack repair device for civil engineering construction. However, this device has the following shortcomings in practical use:

[0004] The aforementioned device uses a rotating cylinder to flatten the filler material at the cracks in the wall, and then a collection trough scrapes off the excess filler material, thus preventing the filler material from falling to the ground. However, in actual use, too much filler material causes the rotating cylinder to flatten the filler material while squeezing the excess filler material upwards. The accumulated excess filler material will fall to the ground over the rotating cylinder. In addition, the device cannot be used to fill cracks at the corners of the wall. Utility Model Content

[0005] In order to improve the problems of inconvenience in using repair devices when there is too much filler and the inability to directly fill and repair cracks at the corners of walls, this application provides a wall crack repair device for civil construction.

[0006] The wall crack repair device for civil construction provided in this application adopts the following technical solution:

[0007] A wall crack repair device for civil construction includes a base and a handle fixedly installed on the base. A notch is provided on one side of the base. A repair mechanism for filling wall cracks is provided on the base. A collection mechanism for assisting the repair mechanism in repair is provided on the base.

[0008] The repair mechanism includes a filling syringe disposed above the front end of the base, a support frame fixedly disposed on the base for support, a fixing component for fixing the filling syringe disposed inside the support frame, a limiting rod for limiting the fixing component disposed on one side of the support frame, and a roller for flattening the filler disposed inside the base.

[0009] The collection mechanism includes a scraper for scraping off excess filler in the middle of the base, a collection box that abuts against the upper surface of the base above the scraper, and an L-shaped plate that engages with the collection box fixedly on the upper surface of the base.

[0010] By adopting the above technical solution, the spring is set so that the roller can compact and flatten the filler on the surface of the wall joint, so that the scraper can scrape off the excess filler and collect it into the collection box. The collection box can be quickly disassembled so that the filler inside the collection box can be poured out. The fixing component and the limiting plate make the filling syringe rotate, so that the device can fill the cracks at the corner of the wall.

[0011] Preferably, the limiting rod extends through one side of the support frame.

[0012] By adopting the above technical solution, the limiting rod can provide a limiting function for the fixed component.

[0013] Preferably, two T-shaped grooves are provided on both sides of the notch for the T-shaped block to slide.

[0014] By adopting the above technical solution, the T-shaped block can slide on the inner wall of the T-shaped groove, giving the roller room to move.

[0015] Preferably, a spring is fixedly provided at the upper end of the T-shaped block, and the upper end of the spring is fixedly connected to the top of the inner wall of the T-shaped groove.

[0016] By adopting the above technical solution, the spring can compress the T-shaped block, so that the roller can flatten and compact the filler.

[0017] Preferably, the inner sides of the two T-shaped blocks are rotatably connected to the rollers.

[0018] By adopting the above technical solution, the T-block and the roller are rotatably connected, enabling the roller to rotate.

[0019] Preferably, the scraper abuts against the center of the notch, and the bottom end of the scraper is flush with the bottom surface of the base.

[0020] By adopting the above technical solution, the scraper blade is flush with the base surface, so that after the scraper blade removes excess filler, the filled part can be kept on the same plane as the wall surface.

[0021] Preferably, a rod is provided in the middle of the side of the collection box to provide limiting support for the collection box.

[0022] By adopting the above technical solution, the insertion rod can provide limiting support for the collection box and prevent the collection box from separating from the base.

[0023] Preferably, the side of the base near the collection box abuts against the side of the collection box near the base.

[0024] By adopting the above technical solution, the base and the collection box abut against each other, allowing the collection box to be snapped onto the surface of the base, thus enhancing stability.

[0025] In summary, this application includes the following beneficial technical effect:

[0026] By incorporating springs, the rollers can compact and flatten the filler on the surface of the wall joints, allowing the scraper to remove excess filler and collect it into the collection box. The collection box can be quickly disassembled to allow the filler inside to be emptied. The fixing components and limiting plates allow the filling syringe to rotate, enabling the device to fill cracks at the corners of the walls. Attached Figure Description

[0036] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0037] Example 1

[0038] This application discloses a wall crack repair device for civil engineering construction.

[0039] Reference Figures 1-3 A wall crack repair device for civil construction includes a base 1, with the bottom sides of the handle 11 fixedly connected to both sides of the base 1. The handle 11 is provided to facilitate force application, making it convenient to pick up and use the device. A notch 12 is provided at the front end of the base 1, and the inner middle of the notch 12 is set as a sloping structure to facilitate scraping by the scraper 32 installed later. A repair mechanism 2 is provided on the base 1, which can fill and repair wall cracks. A collection mechanism 3 is provided on the base 1, which can scrape off excess filler from the wall surface after filling.

[0040] When in use, hold handle 11 to lift the entire device so that the bottom surface of base 1 abuts against the surface of the wall crack, and keep the wall crack in the middle of base 1. Move from the bottom to the top of the crack until the wall crack is filled and repaired. The wall crack is filled by repair mechanism 2, and the excess filler is scraped off and recycled by collection mechanism 3, so that the surface of the wall crack after filling is flat.

[0041] Reference Figures 1-4 The repair mechanism 2 includes a filling syringe 21 positioned above the front end of the base 1. The filling syringe 21 contains filler for filling and repairing cracks on the wall surface. A support frame 22 is fixedly connected to the side of the base 1 closest to the support frame 22. A fixing component 23 is fitted onto the surface of the filling syringe 21. The fixing component 23 includes two arc-shaped plates 231 and an arc-shaped plate 232 corresponding to the arc-shaped plates 231. Both arc-shaped plates 231 and 232 have connecting holes on their surfaces, allowing them to be fixed together by bolts passing through the connecting holes. Two connecting plates 233 are fixedly installed on both sides of the arc-shaped plates 231. The inner side of the connecting plates 233 is connected to the arc-shaped plate 232. 32. Both the inner surfaces of the arc-shaped plate 231 and the arc-shaped plate 232 are provided with silicone to firmly fix the filling syringe 21 and enhance stability. The upper end of the side of the connecting plate 233 is rotatably connected to the upper end of the inner side of the support frame 22. The side of the connecting plate 233 near the limiting plate 25 is fixedly connected to the side of the limiting plate 25 near the connecting plate 233. The bottom of the connecting plate 233 near the limiting plate 25 and the surface of the limiting plate 25 are provided with insertion holes. The side of the support frame 22 near the limiting plate 25 is provided with a limiting rod 24. The surface of the limiting rod 24 is provided with silicone, so that the limiting rod 24 has a certain damping when inserted into the insertion hole and will not disengage from the insertion hole, which can enhance the stability of the connection.

[0042] Two T-shaped grooves 27 are symmetrically opened on the inner side of the base 1 at the notch 12. The inner wall of the two T-shaped grooves 27 is slidably connected to the side of the T-shaped block 28 near the T-shaped groove 27. The top of the inner side of the T-shaped groove 27 is fixedly connected to the upper end of the spring 29. The lower end of the spring 29 is fixedly connected to the upper end of the T-shaped block 28. The two ends of the roller 26 are rotatably connected to the sides of the two T-shaped blocks 28. Utilizing the elasticity of the spring 29, the roller 26 can flatten and compact the filler at the wall joint without causing excess filler to move upward. The length of the roller 26 is half the length of the notch 12, allowing excess filler to flow down through the gap between the roller 26 and the base 1 and be further collected by the collection mechanism 3.

[0043] In use, first, fix the filling syringe 21 by fixing component 23. Loosen the bolts on the surface of arc plate 1 231 and arc plate 232, then insert the filling syringe 21 between arc plate 1 231 and arc plate 232, making the lower end of the filling syringe 21 flush with the surface of the base 1. Then tighten the bolts to firmly fix the filling syringe 21. Push the handle 11 to move the device along the wall crack, and at the same time compress the filling syringe 21, so that the filler inside the filling syringe 21 repairs and fills along the crack. During the movement of the base 1, the filler protruding from the wall surface will contact the roller 26. The elasticity of the spring 29 will keep the roller 26 in contact with the wall surface, so that the filler at the crack is flattened and compacted, thereby achieving the purpose of repairing the crack. Excess filler will remain on the wall surface in the gap between the roller 26 and the base 1, and then be recycled by the collection mechanism 3.

[0044] Reference Figure 1 , Figure 3 , Figure 5The collection mechanism 3 includes a scraper 32 located in the middle of the base 1. The scraper 32 has two mounting holes on its surface. The scraper 32 will wear down during scraping, and multiple spare scrapers 32 are provided for replacement. The scraper 32 abuts against the side of the base 1 closest to the scraper 32. The base 1 has two threaded holes in the middle of the notch 12, allowing the scraper 32 to be fixedly installed to the notch 12 of the base 1 using screws 36. The bottom end of the scraper 32 is flush with the bottom surface of the base 1, enabling it to scrape away excess filler from wall gaps, keeping the wall surface smooth. The upper end of the scraper 32 has an arc-shaped structure to allow the filler on the scraper 32 to fall into the collection box 31. The surface of the base 1 has... The collection box 31 is a semi-enclosed box structure with a limiting hole 38. Two limiting blocks 34 are provided on both sides of the collection box 31. The limiting blocks 34 are fixedly connected to the side of the base 1 near the limiting blocks 34. An L-shaped plate 35 is fixedly provided on the surface of the base 1. The inner side of the L-shaped plate 35 is engaged with the side wall of the collection box 31. An insertion rod 37 is movably provided in the middle of the side of the collection box 31 away from the scraper 32. The end of the insertion rod 37 is engaged with the limiting hole 38. The surface of the insertion rod 37 is provided with silicone to enhance the stability of the insertion with the limiting hole 38 and further make the collection box 31 and the base 1 firmly fixed. A groove 33 is provided at the bottom of the base 1 so that the bottom of the base 1 will not come into contact with the filler in the gap of the wall and avoid damaging the flat surface.

[0045] In use, first, the scraper 32 is fixedly installed onto the base 1 using screws 36. Then, the collection box 31 is snapped onto the base 1. The insertion rod 37 is pulled out, and the bottom of the collection box 31 is placed on the surface of the base 1, with the two sides of the collection box 31 positioned between the two limiting blocks 34. At the same time, the side wall of the collection box 31 is snapped into the L-shaped plate 35. Then, the insertion rod 37 is inserted back in, with the bottom end of the insertion rod 37 positioned inside the limiting hole 38, thereby firmly fixing the collection box 31 onto the base 1. When the device moves along the wall crack, the scraper 32 will scrape off the excess filler, and under the action of gravity, the filler will enter the collection box 31 along the scraper 32 and be collected, thus preventing the excess filler from falling to the ground.

[0046] The implementation principle of the wall crack repair device for civil construction in this application embodiment is as follows: First, fix the filling syringe 21 and the collection box 31. Place the entire device at the lower end of the wall crack through the handle 11, so that the side of the base 1 away from the collection box 31 abuts against the wall surface and moves slowly along the crack. While moving, the filling syringe 21 is compressed, so that the filler inside is squeezed out and fills and repairs the crack. Then, the filler is flattened and compacted by the roller 26, and the corresponding filler is squeezed onto the wall at the gap between the roller 26 and the base 1. Then, the excess filler is scraped off by the scraper 32 and collected into the collection box 31 by gravity for further recycling.

[0047] Example 2

[0048] Reference Figure 6 The difference from Embodiment 1 is that, in a wall crack repair device for civil construction, when repairing cracks at the corner of the wall, the limiting rod 24 is first pulled out, the limiting plate 25 is rotated to adjust the angle of the filling syringe 21, and then the limiting rod 24 is inserted into the insertion hole on the limiting plate 25 for limiting, so that the filling syringe 21 can fill and repair the crack at the corner of the wall. After that, the surface can be slowly smoothed with the spare scraper 32.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
