Description

Technical Field

[0001] This invention belongs to the field of building wall technology, and particularly relates to a device and method for treating gaps in prefabricated building walls. Background Technology

[0002] Prefabricated wall systems are a highly efficient and environmentally friendly processing equipment and method. In the construction of prefabricated buildings, wall modules are first processed and shaped in a factory, and then assembled on site into the required building style.

[0003] Generally, the wall and the base slab are installed by pouring concrete together using sleeves and reinforcing bars. Alternatively, walls can also be connected to each other using sleeves and reinforcing bars. Figure 12 As shown, however, the connection between walls and the connection between walls and the base plate cannot simultaneously use the nesting of sleeves and steel bars; otherwise, once one is nested, the other cannot be nested in.

[0004] For the connection between the base plates of the wall panels, the traditional method is still used for the sake of superior connection stability and reliability. The improvement of this invention lies in the connection method between the walls.

[0005] After the walls are connected, the gaps between them need to be treated to facilitate further wall finishing. Currently, the method used is to smooth the surface with cement, but cracks will appear after prolonged use, affecting the wall's appearance.

[0006] This invention designs a prefabricated building wall gap treatment device and method to solve the above problems. Summary of the Invention

[0007] To achieve the above objectives, the present invention employs the following technical solutions:

[0008] A prefabricated building wall gap treatment device includes a grooving component, a connecting component, and a filling component. The grooving component consists of two symmetrically distributed scrapers and a second mounting shell. The two scrapers are rotatably mounted on the second mounting shell.

[0013] As a preferred embodiment, the connecting assembly further includes a rocker arm, a screw, an eleventh gear, a twelfth gear, a fourth fixing sleeve, a seventh rotating shaft, and mounting sliders. Two screws are symmetrically rotated and mounted on the mounting rod, and two mounting sliders are slidably mounted inside the mounting rod. Each mounting slider has a threaded hole, and the two mounting sliders correspond one-to-one with the two screws and are connected via threaded engagement. In each rocker arm assembly, one end of the rocker arm slidably mounted on the mounting rod is hinged to the corresponding mounting slider. An eleventh gear is fixedly mounted at the end of each screw that is close to the other. A fourth fixing sleeve is fixedly mounted on the mounting rod, and the fourth fixing sleeve is fixedly mounted on a third fixing sleeve by a tightening bolt.

[0014] As a preferred embodiment, the filler includes a positioning plate, a plug strip, and elastic clips, wherein the plug strip is pasted onto the positioning plate, and multiple elastic clips are evenly fixedly installed on the plug strip.

[0015] As a preferred embodiment, the wall treatment assembly for increasing the bonding strength between the filler and the wall includes a first mounting shell, rotating walls, centrifugal blocks, a first rotating shaft, a guide slider, a scraper, a trigger triangular block, and a spring. The first rotating shaft is rotatably mounted on one side of the first mounting shell. Two rotating walls are staggered and fixedly mounted on the first rotating shaft. Each rotating wall has two centrifugal blocks and two scrapers symmetrically mounted. The scrapers are triangular blocks and are slidably mounted on the rotating walls via guide blocks.

[0018] As a preferred embodiment, a handle is mounted on the mounting housing.

[0019] As a preferred embodiment, the positioning plate, the plug strip, and the elastic clip are all made of elastic materials.

[0020] A method for treating gaps in prefabricated building walls: First, when the wall treatment component is installed on the power component, then the rotating wall is inserted into the gap between the two walls to be connected, and the third motor is controlled to work, causing the rotating wall to rotate and the scraper to slide out, forming a burr layer on the side wall surface of the wall.

[0021] Second, when the grooving assembly is installed on the power assembly, the two scrapers are vertically inserted between the two walls, and then the two scrapers are rotated by the third motor; at the same time, the second motor is controlled to work, so that the two scrapers swing along the axis of the second fixed sleeve, and a quarter arc groove is opened on each of the two walls. After the two scrapers are horizontally distributed, the grooving assembly is controlled to move back and forth a short distance, and a groove is opened on each side of the two arc grooves.

[0022] Third, after installing the connecting component onto the power component, insert the mounting rod of the connecting component between the two walls and control the second motor to work, causing the mounting rod to swing into the excavated arc-shaped groove; then stop the second motor and control the first motor to work, causing the end of the swing rod connected to each other to swing outward, forming a sharp corner that inserts into the groove, connecting the two mating walls; after removing the power component from the connecting component, it is necessary to use auxiliary tools to cut off the parts of the fourth fixing sleeve and the seventh rotating shaft on the connecting component that extend beyond the front wall surface of the wall.

[0023] Fourth, after the connecting components are installed, insert the filler strip into the gap between two adjacent walls. Once the filler strip is installed, remove the positioning plate.

[0024] Compared with existing technologies, this invention has specially designed wall treatment components, grooving components, connecting components and filling parts for the connection between walls, which reduces the construction difficulty when using traditional connection methods; at the same time, this invention has specially designed filling parts for the treatment of gaps between walls, which greatly increases the aesthetics of the filled gaps while ensuring the filling requirements are met.

[0038] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following embodiments and drawings are used to illustrate the present invention, but are not intended to limit the scope of the invention.

[0039] A device and method for treating 50mm gaps in prefabricated building walls, such as... Figure 1 , 3 As shown in 7 and 10, it includes a grooving assembly 47, a connecting assembly 48, a filler 49, a wall treatment assembly 46, and a power assembly 7.

[0040] like Figure 6As shown, the power assembly 7 includes a mounting housing 19, a first motor 21, a second motor 25, a third motor 26, a fifth rotating shaft 27, a fifth gear 28, a sixth gear 29, a third fixing sleeve 30, a sixth rotating shaft 31, a seventh gear 32, an eighth gear 33, a ninth gear 34, and a tenth gear 35. The first motor 21, the second motor 25, and the third motor 26 are fixedly mounted inside the mounting housing 19. The third fixing sleeve 30 is rotatably mounted inside the mounting housing 19. One end of the third fixing sleeve 30 is fixedly mounted with the ninth gear 34, and the output end of the second motor 25 is fixedly mounted with the tenth gear 35. The tenth gear 35 and the ninth gear... Gear 34 meshes; the sixth shaft 31 is rotatably installed inside the mounting housing 19, one end of the sixth shaft 31 has a square hole, and the other end of the sixth shaft 31 is fixedly installed with the sixth gear 29; the output shaft of the first motor 21 is fixedly installed with the fifth gear 28, and the fifth gear 28 meshes with the sixth gear 29; the fifth shaft 27 is rotatably installed inside the mounting housing 19, one end of the fifth shaft 27 has a square hole, and the other end of the fifth shaft 27 is fixedly installed with the seventh gear 32; the output shaft of the third motor 26 is fixedly installed with the eighth gear 33, and the eighth gear 33 meshes with the other gear; a handle 20 is installed on the mounting housing 19.

[0041] When the second motor 25 is working, it drives the tenth gear 35 to rotate, which in turn drives the ninth gear 34 to rotate, and the ninth gear 34 to rotate, which in turn drives the third fixed sleeve 30 to rotate. When the first motor 21 is working, it drives the fifth gear 28 to rotate, which in turn drives the sixth gear 29 to rotate, and the sixth gear 29 to rotate, which in turn drives the sixth rotating shaft 31 to rotate. When the third motor 26 is working, it drives the eighth gear 33 to rotate, which in turn drives the seventh gear 32 to rotate, and the seventh gear 32 to rotate the fifth rotating shaft 27.

[0042] like Figure 1 , 2As shown, the wall treatment component 46 includes a first mounting shell 1, a rotating wall 2, a centrifugal block 3, a first rotating shaft 4, a guide slider 9, a scraper 10, a trigger triangular block 11, a spring 12, a second rotating shaft 5, a first gear 6, and a first fixing sleeve 8. The first rotating shaft 4 is rotatably mounted on one side of the first mounting shell 1. Two rotating walls 2 are staggered and fixedly mounted on the first rotating shaft 4. Each rotating wall 2 has two centrifugal blocks 3 and two scrapers 10 symmetrically mounted. The scrapers 10 are triangular blocks and are slidably mounted on the rotating wall 2 via guide blocks. Each rotating wall 2 has a trigger triangular block 11 slidably mounted inside it. One end of the corner block 11 is fixedly connected to the centrifugal block 3 on the corresponding side, and a spring 12 is installed between the other end of the trigger triangle block 11 and the rotating wall 2; the trigger triangle block 11 cooperates with the scraper block 10 on the corresponding side; a second rotating shaft 5 is rotatably installed inside the first mounting shell 1, and a first gear 6 is fixedly installed on both the second rotating shaft 5 and the first rotating shaft 4; the two first gears 6 mesh; a first fixing sleeve 8 is fixedly installed on the first mounting shell 1; the first fixing sleeve 8 can be installed on the third fixing sleeve 30 by tightening bolts 18, one end of the second rotating shaft 5 is a square shaft, and the second rotating shaft 5 cooperates with the square hole on the fifth rotating shaft 27.

[0043] The first fixed sleeve 8 is fixedly installed on the third fixed sleeve 30 by tightening bolt 18. When the second motor 25 is not working, the third fixed sleeve 30 is relatively stationary. At this time, the third fixed sleeve 30 can fix the first fixed sleeve 8 and restrict the rotation of the first fixed sleeve 8. When the wall treatment component 46 is installed on the power component 7, the first fixing sleeve 8 is fixed by the third fixing sleeve 30. At this time, when the fifth rotating shaft 27 is controlled to rotate, the fifth rotating shaft 27 will drive the second rotating shaft 5 to rotate through the cooperation of the square shaft and the square hole. The rotation of the second rotating shaft 5 drives the first rotating shaft 4 to rotate through the two first gears 6. The rotation of the first rotating shaft 4 drives the two rotating walls 2 to rotate. The rotation of the rotating walls 2 will cause the centrifugal block 3 installed on it to generate centrifugal force. The centrifugal block 3 slides outward. The outward sliding of the centrifugal block 3 will drive the trigger triangle block 11 to slide. The trigger triangle block 11 will push the corresponding scraper block 10 outward through the inclined surface, so that the sharp end of the scraper block 10 slides out of the rotating wall 2. The rotating wall 2 in the wall treatment component 46 is inserted between the two walls to be connected. Then the rotating wall 2 is controlled to rotate, and the scraper block 10 slides out. In this case, the scraper block 10 driven by the rotating wall 2 will process the side wall of the wall, so that a burr layer is formed on the side wall of the wall 50, which strengthens the stability of the subsequent filling part 49 and the wall. In this invention, the scrapers 10 installed on the two rotating walls 2 can be designed on the same side, so that after one side of the wall is processed, they can be moved to the other side to process the other side of the wall; or they can be designed on different sides, so that the two walls connected to each other can be processed at the same time.

[0044] like Figure 3 ,4 As shown in Figure 5, the excavation assembly includes a scraper 13, a second mounting shell 14, a third rotating shaft 16, a second fixing sleeve 17, a fourth rotating shaft 22, a third gear 23, and a fourth gear 24. Two third rotating shafts 16 are symmetrically rotated and mounted within the second mounting shell 14. Two scraper blades 13 are fixedly mounted on the two third rotating shafts 16. A third gear 23 is fixedly mounted at one end of each of the two third rotating shafts 16 within the second mounting shell 14. A second fixing sleeve 17 is fixedly mounted at the lower end of the second mounting shell 14. The second fixing sleeve 17 is fixedly mounted on the third fixing sleeve 30 by a tightening bolt 18. The fourth rotating shaft 22 is rotatably mounted within the second mounting shell 14. A fourth gear 24 is fixedly mounted at one end of the fourth rotating shaft 22, and the fourth gear 24 meshes with the two third gears 23. The other end of the fourth rotating shaft 22 is a square shaft, and the square shaft end of the fourth rotating shaft 22 is connected to the square hole of the fifth rotating shaft 27.

[0045] When the slotted assembly 47 is installed on the power assembly 7, the second fixed sleeve 17 is fixedly installed on the third fixed sleeve 30 by tightening bolts 18; at this time, controlling the rotation of the fifth rotating shaft 27 can drive the fourth rotating shaft 22 to rotate under the cooperation of the square shaft and the square hole. The rotation of the fourth rotating shaft 22 drives the fourth gear 24 to rotate. The rotation of the fourth gear 24 drives the two third gears 23 to rotate. The rotation of the two third gears 23 drives the two third rotating shafts 16 to rotate. The rotation of the two third rotating shafts 16 drives the two scrapers 13 to rotate. When the third fixed sleeve 30 rotates, it can drive the second fixed sleeve 17 to rotate. When grooving two mating walls, the two scraper blades 13 of the grooving assembly 47 are inserted vertically between the two walls 50. Then, the fifth rotating shaft 27 is rotated by the third motor 26, causing the two scraper blades 13 to rotate. Simultaneously, the second motor 25, a geared motor, is controlled to operate. The operation of the second motor 25 drives the second mounting housing 14 to rotate via the third fixing sleeve 30 and the second fixing sleeve 17. The second mounting housing 14 then causes the two scraper blades 13 to swing along the axis of the second fixing sleeve 17. Figure 11 As shown, quarter-circular grooves 51 are cut into the two walls respectively. After the two scrapers 13 are horizontally distributed, the grooving component 47 is controlled to move back and forth a short distance to create a groove 52 on each side of the two arc grooves 51. This facilitates the insertion of the swing rod 37 in the subsequent connecting component 48 after it is opened.

[0046] like Figure 7 , 8As shown in Figure 9, the connecting assembly 48 includes a rocker arm 37, a mounting rod 36, a screw 38, an eleventh gear 39, a twelfth gear 40, a fourth fixing sleeve 41, a seventh rotating shaft 42, and mounting sliders 15. Two screws 38 are symmetrically rotated and mounted on the mounting rod 36, and two mounting sliders 15 are slidably mounted within the mounting rod 36. Each mounting slider 15 has a threaded hole, and the two mounting sliders 15 correspond one-to-one with the two screws 38 and are connected by a threaded engagement. A set of rocker arm 37 assemblies is symmetrically mounted on both ends of the mounting rod 36, swinging up and down. Each set of rocker arm 37 assemblies consists of two rocker arms 37, with their closest ends hinged together. One end of a rocker arm 37 is hinged to the mounting rod 36, and the other end of another rocker arm 37 is hinged to the corresponding mounting slider 15. An eleventh gear 39 is fixedly installed at one end of each screw 38 that is close to the other. A fourth fixing sleeve 41 is fixedly installed on the mounting rod 36. The fourth fixing sleeve 41 is fixedly installed on the third fixing sleeve 30 by tightening bolts 18. A seventh rotating shaft 42 is rotatably installed inside the fourth fixing sleeve 41. A twelfth gear 40 is fixedly installed at one end of the seventh rotating shaft 42, and the twelfth gear 40 meshes with the two eleventh gears 39. The other end of the seventh rotating shaft 42 is a square shaft, and the square shaft end of the seventh rotating shaft 42 is connected to the square hole of the sixth rotating shaft 31.

[0047] After the connecting assembly 48 is installed on the power assembly 7, the second fixing sleeve 17 is fixedly installed on the third fixing sleeve 30 by tightening bolts 18. After inserting the mounting rod 36 of the connecting assembly 48 between the two walls 50, the second motor 25 is controlled to work. The second motor 25 is a geared motor. The operation of the second motor 25 will drive the mounting rod 36 to rotate through the third fixing sleeve 30 and the fourth fixing sleeve 41, causing the mounting rod 36 to swing into the excavated arc-shaped groove 51. Then, the second motor 25 is stopped, and the first motor 21 is controlled to work. The first motor 21 drives the sixth rotating shaft 31 to rotate. The rotation of the sixth rotating shaft 31 drives the seventh rotating shaft 42 to rotate. The rotation of the seventh rotating shaft 42 drives the twelfth gear. When wheel 40 rotates, the twelfth gear 40 rotates, which drives the eleventh gear 39 to rotate. The eleventh gear 39 rotates, which drives the screw 38 to rotate. The rotation of the screw 38, under the action of the thread, causes the mounting slider 15 to slide. The sliding of the mounting slider 15 will drive the corresponding swing rod 37 to swing outward, forming a sharp corner that inserts into the groove 52, connecting the two mating walls 50. After the power component 7 is removed from the connecting component 48, the part of the fourth fixing sleeve 41 and the seventh rotating shaft 42 on the connecting component 48 that exceeds the front wall surface of the wall 50 needs to be cut off with an auxiliary tool. A larger part needs to be cut off to facilitate the subsequent installation of the filler 49.

[0048] like Figure 10As shown, the filling component 49 includes a positioning plate 43, a plug strip 44, and elastic clips 45. The plug strip 44 is attached to the positioning plate 43, and multiple elastic clips 45 are evenly fixedly installed on the plug strip 44. The positioning plate 43, the plug strip 44, and the elastic clips 45 are all made of elastic materials.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0050] Implementation: When using the device designed in this invention, during use, firstly, when the wall treatment component 46 is installed on the power component 7, the first fixing sleeve 8 is fixed by the third fixing sleeve 30. At this time, the third motor 26 is controlled to work. When the third motor 26 works, it can drive the eighth gear 33 to rotate. The rotation of the eighth gear 33 drives the seventh gear 32 to rotate. The rotation of the seventh gear 32 drives the fifth rotating shaft 27 to rotate. The fifth rotating shaft 27 drives the second rotating shaft 5 to rotate through the cooperation of the square shaft and the square hole. The rotation of the second rotating shaft 5 drives the first rotating shaft 4 to rotate through the two first gears 6. The rotation of the first rotating shaft 4 drives... The two rotating walls 2 rotate, which causes the centrifugal blocks 3 installed on them to generate centrifugal force. The centrifugal blocks 3 slide outward, and the outward sliding of the centrifugal blocks 3 will drive the trigger triangle block 11 to slide. The trigger triangle block 11 will push the corresponding scraper block 10 outward through the inclined surface, so that the sharp end of the scraper block 10 slides out of the rotating wall 2. The rotating wall 2 in the wall surface treatment component 46 is inserted between the two walls to be connected, and then the rotating wall 2 is controlled to rotate. The scraper block 10 slides out. In this case, the scraper block 10 driven by the rotating wall 2 will process the side wall of the wall, so that a burr layer is formed on the side wall of the wall 50.

[0051] Then, when the slotting assembly 47 is installed on the power assembly 7, the second fixing sleeve 17 is fixedly installed on the third fixing sleeve 30 by tightening bolts 18; the two scrapers 13 of the slotting assembly 47 are inserted vertically between the two walls 50, and then the fifth rotating shaft 27 is rotated by the third motor 26; the rotation of the fifth rotating shaft 27 can drive the fourth rotating shaft 22 to rotate under the cooperation of the square shaft and the square hole, the rotation of the fourth rotating shaft 22 drives the fourth gear 24 to rotate, the rotation of the fourth gear 24 drives the two third gears 23 to rotate, the rotation of the two third gears 23 drives the two third rotating shafts 16 to rotate, and the rotation of the two third rotating shafts 16 drives the two scrapers 13 to rotate; at the same time, the second motor 25 is controlled to work. The second motor 25 is a geared motor. The operation of the second motor 25 will drive the second mounting shell 14 to rotate through the third fixing sleeve 30 and the second fixing sleeve 17. The second mounting shell 14 drives the two scrapers 13 to swing along the axis of the second fixing sleeve 17, such as Figure 11As shown, quarter-circular grooves 51 are cut into the two walls respectively. After the two scrapers 13 are horizontally distributed, the grooving assembly 47 is controlled to move back and forth a short distance to cut a groove 52 on both sides of the two arc grooves 51.

[0052] Afterwards, the connecting component 48 is installed on the power component 7, and the second fixing sleeve 17 is fixedly installed on the third fixing sleeve 30 by tightening bolts 18. After inserting the mounting rod 36 of the connecting component 48 between the two walls 50, the second motor 25 is controlled to work. The second motor 25 is a geared motor. The operation of the second motor 25 will drive the mounting rod 36 to rotate through the third fixing sleeve 30 and the fourth fixing sleeve 41, causing the mounting rod 36 to swing into the excavated arc-shaped groove 51. Then, the second motor 25 is stopped, and the first motor 21 is controlled to work. The first motor 21 drives... The sixth rotating shaft 31 rotates, which drives the seventh rotating shaft 42 to rotate. The seventh rotating shaft 42 rotates, which drives the twelfth gear 40 to rotate. The twelfth gear 40 rotates, which drives the eleventh gear 39 to rotate. The eleventh gear 39 rotates, which drives the screw 38 to rotate. The rotation of the screw 38, under the action of the thread, causes the mounting slider 15 to slide. The sliding of the mounting slider 15 will drive the corresponding swing rod 37 to swing. This causes the end of the swing rod 37 connected to each other to swing outward, forming a sharp corner that inserts into the groove 52, connecting the two mating walls 50.

[0053] After the connecting component 48 is installed, the plug strip 44 of the filler 49 is inserted into the gap between two adjacent walls 50. The elastic clip 45 is held in place by the elasticity of the clips on the sides of the two walls 50. The burr layer increases the stability of the installation of the elastic clip 45. The positioning plate 43 is used to position the plug strip 44. After the plug strip 44 is installed, the positioning plate 43 is close to the front of the wall. So when the positioning plate 43 is removed, the side of the plug strip 44 without the elastic clip 45 is flush with the front of the wall, ensuring the aesthetics after the subsequent manual cement slurry.
