Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated building design, in particular to a prefabricated wall and a construction method thereof. Background Art

[0002] With the development of construction technology, various building structures have also begun to be improved. Prefabricated buildings are made by pre-forming part of the building's walls and then assembling them on the construction site. Compared with traditional walls built of bricks, the walls of prefabricated buildings can not only be made of lighter materials, but also be easy to assemble and construct, with a shorter construction period. At the same time, the walls of prefabricated buildings also facilitate rapid disassembly and modification of the building layout in the later stage.

[0003] However, in existing prefabricated walls, bolts are mainly used to fix the walls, and the wall itself adopts a solid structure, which results in a large number of bolts that need to be fixed, and it still takes a lot of time to install and remove them. The large number of bolt holes and other structures left after the bolts are installed also require additional decoration to be beautiful. In addition, the solid wall will also make it very inconvenient to subsequently modify the pipelines in the wall or replace the fillers in the wall.

[0041] Connecting shaft device 2, see Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7The connecting shaft device 2 includes a hollow shaft 202 which is rotatably installed with the rear wall plate 101 and is used for rotatably installing the air vent 10. The air vent 10 can be rotated by using the hollow shaft 202 as the rotating shaft. The left and right ends of the hollow shaft 202 are respectively rotatably installed with rotating docking seats 204, and the rotating docking seats 204 are fixedly installed with the rear wall plate 101. The air vent 10 is installed and selectively connected with the hollow shaft 202 through the limit connection device 4 and selectively drives the hollow shaft 202 to rotate forward and reversely. When the air vent 10 is in normal use, when the operator opens the air vent 10 or closes the air vent 10 and needs to rotate the air vent 10, the hollow shaft 202 will not be driven to rotate. Only after being connected through the limit connection device 4 will the hollow shaft 202 be driven to rotate forward or reverse. In addition, a rubber pad is provided at the contact position between the air vent 10 itself and the side of the window 18 to form a damping connection, thereby relying on the rubber pad to generate The damping hinders the rotation of the vent window 10, ensuring that the vent window 10 can continue to maintain the corresponding angle position by relying on the damping generated by the rubber pad after being manually rotated to a specific angle, and a fixed conduit 13 is fixed in the rear wall panel 101, which is concentrically connected with the hollow shaft 202 and forms a convenient internal pipeline to cross different wall units 1 for installation, and a pipeline interface 9 for installing external pipelines is provided on the front wall panel 102, and a pipeline inlet and outlet 12 connected to the interior of the fixed conduit 13 is opened on the fixed conduit 13, and the interior of the pipeline interface 9 sends the external pipeline from the pipeline inlet and outlet 12 to the interior of the fixed conduit 13 through a guide pipe 19 fixed on the front wall panel 102, and the pipelines that need to be installed together by adjacent wall units 1 can pass through the interior of the fixed conduit 13 and the interior of the hollow shaft 202, so that these pipelines can cross the wall unit 1 without worrying that these pipelines are disturbed by the movement of other moving parts inside the wall unit 1;

[0042] Limit push device 5, please refer to Figure 2 , Figure 4 and Figure 7The position limiting pushing device 5 includes a worm wheel 501 rotatably mounted on the rear wall plate 101, and a hollow worm 201 for driving the worm wheel 501 to rotate is integrally formed on the hollow shaft 202, a rack 504 meshing with the worm wheel 501 is slidably mounted on the rear wall plate 101, and a connecting plate 502 is fixedly mounted at the end of the rack 504, a plug hole 17 is opened on the side of the rear wall plate 101, and a plug hole 17 for inserting adjacent plug holes on two adjacent rear wall plates 101 is integrally formed on the connecting plate 502. The clamping rod 503 is used to limit and fix the two adjacent rear wall panels 101 in the hole 17, and the front wall panel 102 is integrally formed with a fixed docking plate 7 corresponding to the plug-in hole 17, and the clamping rod 503 plugs and fixes the plug-in hole 17 and the fixed docking plate 7 together to fix the rear wall panel 101 and the front wall panel 102. The forward and reverse movement of the hollow shaft 202 can drive the worm wheel 501 to rotate by the hollow worm 201, and the rack 504 is driven to move linearly by the worm wheel 501, so that the clamping rod 503 is used to fix the rear wall panel 101 and the front wall panel 102. The clamping rod 503 is inserted into the insertion hole 17 or the clamping rod 503 is pulled out of the insertion hole 17. When the clamping rod 503 is inserted into the insertion hole 17 and moves to the limit of travel, the clamping rod 503 will pass through the adjacent insertion holes 17 on two different rear wall panels 101 to connect different adjacent wall units 1. At the same time, when the clamping rod 503 is inserted into the insertion hole 17, it will also pass through the docking hole on the fixed docking plate 7 to fix the fixed docking plate 7 and the rear wall panel 101 together. In this way, the purpose of fixing the rear wall panel 101 and the front wall panel 102 together is achieved. When the wall unit 1 needs to be disassembled or the front wall panel 102 needs to be opened to perform maintenance inside the wall unit 1, such as modifying the pipeline or replacing the functional filler 8, the clamping rod 503 can be disengaged from the plug hole 17 by reversing the hollow shaft 202, so that the front wall panel 102 and the rear wall panel 101 can be separated again, and different rear wall panels 101 can be separated from each other;

[0043] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8The limit connection device 4 is installed in the air vent 10 through the adjustment matching hole 20, and the limit connection device 4 includes a rotating rod 401 that is threadedly connected to the adjustment matching hole 20, and the end of the rotating rod 401 is rotatably installed with a rotating block 402 located in the adjustment matching hole 20, and the rotating block 402 is integrally formed with a matching slider 403 that is slidably installed along a guide matching groove opened on the inner wall of the adjustment matching hole 20, and the end of the rotating block 402 is connected to a clamping head 405 located in the adjustment matching hole 20 through an extrusion spring 404, and the left and right ends of the rotating docking seat 204 are symmetrically provided with a first ratchet 207 and a second ratchet 203 in opposite directions, and the air vent 10 is rotated in the corresponding first ratchet 207 and the second A limiting connection device 4 is respectively installed at the ratchet 203, and the ends of the clamping heads 405 located on the two limiting connection devices 4 are respectively fixed with the first ratchet 207 or the second ratchet 203 at the corresponding position through spherical protrusions. When the limiting connection device 4 is in use, the position of the rotating rod 401 in the adjustment matching hole 20 will be changed by rotating the rotating rod 401. When the rotating rod 401 is rotated in the direction away from the adjustment matching hole 20, the clamping head 405 will move away from the first ratchet 207 or the second ratchet 203, thereby losing the fixing effect on the first ratchet 207 or the second ratchet 203. When the rotating rod 401 is rotated in the direction of going deeper into the adjustment matching hole 20, the clamping head 405 The tightening head 405 will be firmly squeezed on the first ratchet 207 or the second ratchet 203 under the squeezing of the squeezing spring 404. At this time, the first ratchet 207 or the second ratchet 203 can be used to cooperate with the clamping head 405 to realize the unidirectional movement of the hollow shaft 202. Specifically, the first ratchet 207 is used to cooperate with the clamping head 405 located on the left side of the air vent 10 to realize the forward rotation of the hollow shaft 202, and the second ratchet 203 is used to cooperate with the clamping head 405 located on the right side of the air vent 10 to realize the reverse rotation of the hollow shaft 202. In actual use, when the wall unit 1 needs to be installed, the clamping head 405 located on the left side of the air vent 10 is driven to the first ratchet 207 through the rotating rod 401 to be aligned with the first ratchet 207. 07, and then the user repeatedly opens and closes the vent window 10. During the repeated opening and closing process, the vent window 10 can only transmit the rotational movement during the forward rotation to the hollow shaft 202 through the first ratchet 207, thereby driving the forward rotation of the hollow shaft 202. After the adjustment is completed, the clamping head 405 on the left side of the vent window 10 is adjusted to the non-working position through the rotating rod 401 again. When the front wall panel 102 needs to be removed, it is only necessary to fix the clamping head 405 on the right side of the vent window 10 with the second ratchet 203, and then repeatedly open and close the vent window 10 to drive the hollow shaft 202 to reverse. After the disassembly is completed, the clamping head 405 on the right side of the vent window 10 is adjusted to the non-working position again.

[0044] In this embodiment, the positive rotation of the hollow shaft 202 can be used to drive the clamping rod 503 on the limit pushing device 5 to fix the front wall panel 102 and the rear wall panel 101 together. At the same time, the rear wall panels 101 of adjacent wall units 1 can also be fixed together to assemble to form the required building wall, which facilitates the rapid assembly of assembled buildings. The clamping rod 503 can also be pulled out of the plug-in hole 17 again by the reverse rotation of the hollow shaft 202 to separate the front wall panel 102 and disassemble the adjacent wall units 1. Under the premise of being able to complete the above functions, the hollow shaft 202 can also be used as the rotating shaft of the air vent 10, and the air vent 10 can also be used as a power input component to drive and change the rotation direction of the hollow shaft 202. In this way, the front wall panel 102 can be fixed without It is necessary to additionally design a component for driving the hollow shaft 202 to rotate so that the surface of the front wall panel 102 is neater. On the other hand, the inner cavity of the hollow shaft 202 can also be used in conjunction with the fixed conduit 13 to realize the installation and guidance of the pipeline inside the wall unit 1, so that the pipeline can be arranged more neatly and avoid collision between the pipeline and other moving parts in the wall unit 1, thereby realizing the protection of the pipeline. Therefore, the hollow shaft 202 simultaneously realizes the convenience of installation of the ventilation window 10, control of the disassembly and installation of the wall unit 1, and protection of the pipeline inside the wall unit 1, enriching the function of the hollow shaft 202, thereby solving the problem that the installation and disassembly of the existing prefabricated wall are cumbersome and inconvenient to modify, and can effectively improve the construction convenience of the prefabricated wall.

[0045] Embodiment 2

[0046] See attached Figure 2 , Figure 4 , Figure 5 and Figure 8On the basis of the first embodiment, a docking fixing device 3 for docking the connecting shaft device 2 is provided on the fixed conduit 13, and the docking fixing device 3 includes a fixed ring 301 fixedly installed with the fixed conduit 13, and a connecting ring 303 sleeved on the end of the fixed conduit 13 is connected to the fixed ring 301 through a first return spring 302, and a rotating docking ring 304 is rotatably installed at the end of the connecting ring 303, and the fixed conduit 13 is provided with a guide groove 14 for guiding the sliding of the connecting ring 303 along its own axial direction, and The inner side of the connecting ring 303 is integrally formed with a guide protrusion that slides with the guide groove 14, and the end of the hollow shaft 202 is integrally formed with a docking head 205 that is sleeved with the rotating docking ring 304, and a clamping groove 206 is provided on the docking head 205, and a clamping protrusion 305 that clamps with the clamping groove 206 is integrally formed on the inner wall of the rotating docking ring 304. This embodiment facilitates the maintenance of the connecting shaft device 2. When the connecting shaft device 2 fails and needs to be replaced, the rotating docking ring 304 is moved to the fixed The side squeezing of the conduit 13 can make the hollow shaft 202 disengage from the matching state with the fixed conduit 13, and then the rotating docking seat 204 can be removed to remove the hollow shaft 202 from the rear wall panel 101, and then the pipelines located in the hollow shaft 202 can be taken out in turn and replaced with a new hollow shaft 202, and the pipelines can also be placed in the new hollow shaft 202. When the hollow shaft 202 is working normally, the rotating docking ring 304 on the docking and fixing device 3 can also keep rotating synchronously with the hollow shaft 202, and prevent the end of the hollow shaft 202 from being damaged by wear and other problems caused by uneven force. In particular, it avoids the problem that the worm wheel 501 and the hollow worm 201 are stuck due to the low coaxiality of the hollow shaft 202 due to long-term use, causing the hollow shaft 202 to fail to work normally. Since the working reliability of the hollow shaft 202 is greatly improved, the problem that the installation and disassembly of the existing assembled wall is cumbersome and inconvenient to modify is further solved, which can effectively improve the construction convenience of the assembled wall.

[0047] Embodiment 3

The pre-fixing device 6 includes an annular connecting seat 604 fixed on the side of the pre-fixing hole 16, and a pushing block 601 is connected to the annular connecting seat 604 through a second reset spring 602. A plug-in limit rod 603 for inserting into adjacent pre-fixing holes 16 on different wall units 1 for fixing is fixed on the pushing block 601. An installation port 15 is provided on the side of the rear wall panel 101. In order to ensure that the rear wall panels 101 in adjacent wall units 1 or the rear wall panels 101 and the external building frame are deflected during installation, the pre-fixing device 6 can be used for pre-fixing. During the pre-fixing time, the pre-fixing holes 16 of the two adjacent rear wall panels 101 are connected by a plug-in limit rod 603. The plug-in effect of the limit rod 603 is limited together, so that this method can be used to align adjacent rear wall panels 101. The alignment between the rear wall panel 101 and the building frame is also achieved in this way, except that a pre-set hole aligned with the pre-fixing hole 16 needs to be reserved in advance on the building frame. If the side of the wall unit 1 also needs to be fixed, that is, when the wall unit 1 moves left and right or up and down, the operator can also tighten the end of the plug-in limit rod 603 through the installation port 15 through a nut to fix it on another rear wall panel 101 or the building frame. In this way, the wall unit 1 can be completely fixed. In this way, it is ensured that the wall units 1 can be quickly and correctly assembled, further solving the problem that the installation and disassembly of the existing prefabricated wall is cumbersome and inconvenient to modify, and can effectively improve the construction convenience of the prefabricated wall.

[0052] Step 2: Press the front wall panel 102 onto the rear wall panel 101, and then adjust the hollow shaft 202 to the forward rotation mode through the limit connection device 4, so as to use the rotational movement of the vent window 10 when it is opened and closed to drive the hollow shaft 202 to rotate, and then use the hollow shaft 202 to fix the front wall panel 102 to the rear wall panel 101 through the clamping rod 503 in the limit push device 5, and at the same time, fix the rear wall panel 101 to the reserved connection piece on the building frame or the adjacent rear wall panels 101 through the clamping rod 503, and then adjust the hollow shaft 202 to the non-rotation mode through the limit connection device 4, at this time, the rotation of the vent window 10 when it is opened or closed will not drive the hollow shaft 202 to rotate, and the installation process is completed;

[0053] Step three: adjust the hollow shaft 202 to the reversal mode through the limiting connection device 4. At this time, the rotation of the air vent 10 will drive the hollow shaft 202 to reverse, thereby separating the front wall panel 102 and the rear wall panel 101, and at the same time separating the rear wall panel 101 from the adjacent rear wall panel 101 or the building frame. Then, remove the limiting pins or bolts in the rear wall panel 101 to remove the rear wall panel 101 to complete the disassembly process.
