Description
Technical Field
[0001] This invention relates to the field of building construction technology, specifically to a prefabricated folding house and its construction method. Background Technology
[0002] Prefabricated housing is a type of housing that is professionally designed, standardized, modular, and universally produced. It is easy to dismantle, install, transport, and store, and can be reused and rotated multiple times. The main structural components are manufactured on the assembly line in the housing factory and transported to the construction site, where installation workers assemble the main structure on-site. This achieves factory prefabrication and on-site assembly construction, with no wet work, less noise, dust, and waste, and less affected by the climate. It does not use clay bricks and is disassembled and recyclable.
[0003] Currently, prefabricated houses on the market generally use bolt connections during construction, requiring manual labor to carry bolts and bolt removal tools to disassemble and install them.
[0004] The installation of bolts requires additional disassembly and assembly tools, which is very inconvenient. Furthermore, after the prefabricated houses have been used for a long time, the bolt connections may rust. When disassembling, rust remover needs to be used to remove the rust from the bolts before multiple wall panels can be removed, which is very troublesome and consumes a lot of manpower and time, greatly reducing construction efficiency.

[0009] The short board is equipped with a buffer device inside, the buffer device comprising:
[0010] A buffer rod, the bottom of which is fixedly connected to the inside of the short plate, the inside of which is fixedly connected to one end of a buffer spring, the other end of which is fixedly connected to one end of a buffer block, and the other end of which fits into the inside of a circular groove, the circular groove being formed inside the connecting rod;
[0011] The long plate is provided with a folding mechanism inside, the folding mechanism including:
[0012] A semi-circular rod is provided, with one end fixedly connected to the interior of a long plate, a slotted side of the semi-circular rod engaging with the outer wall of a limiting block, a side of the limiting block fixedly connected to one end of a limiting spring, the other end of the limiting spring fixedly connected to the interior of the long plate, a side of the limiting block fixedly connected to one end of an L-shaped rod, and the middle outer wall of the long plate fixedly connected to the side of a hinge by bolts.
[0013] Preferably, the other end of the pull rod is fixedly connected to the side of the pull block.
[0014] Preferably, the other end of the L-bar is fixedly connected to the side of the movable block.
[0015] Preferably, the number of upper and lower short rods in the connecting device is set to two sets, and the two sets are symmetrically distributed on both sides of the moving block.
[0016] Preferably, the number of upper short rods, lower short rods, moving blocks, locking blocks, clamping springs, pull rods, and blocking rods in the connecting device is set to two sets, and the two sets of upper short rods, lower short rods, moving blocks, locking blocks, clamping springs, pull rods, and blocking rods are symmetrically distributed on both sides of the connecting rod.
[0017] Preferably, the number of connecting devices is set to four groups, and the four groups of connecting devices are symmetrically distributed in pairs on both sides of the short plate, with each pair of connecting devices symmetrically distributed vertically on the side of the short plate.
[0018] Preferably, the number of hinges is set to two sets, and the two sets of hinges are symmetrically distributed on the middle of the side of the long board.
[0019] Preferably, a door frame is provided inside one of the sets of short boards.
[0020] Preferably, the top of the roof is triangular.
[0021] A prefabricated folding house and its construction method, the prefabricated folding house comprising the following steps:
[0022] S1. When it is necessary to install the folding house, the foundation should be leveled first to make the ground flat and a cement floor should be laid.
[0023] S2. Unfold the folded long board so that half of the long board opens around the hinge. At this time, the semi-arc rod inside one half of the long board enters the arc groove inside the other half of the long board. When the long board reaches the horizontal position, under the action of the limit spring, the locking block enters the side locking groove of the semi-arc rod. If the long board needs to be transported again, the long board needs to be folded and the moving block pushed to the left to move the L rod to the left, causing the limit block to leave the side locking groove of the semi-arc rod. At this time, one half of the long board can be rotated around the hinge, and the long board can be folded.
[0024] S3. After the long plate is unfolded, align the connecting rod on the side of the long plate with the opening of the short plate and start assembling them. At this time, the square ring touches the protrusion inside the short plate, and the connecting rod can continue to move. The square ring moves upward relative to the connecting rod, which drives the upper and lower short rods and the upper short rod to rotate in opposite directions, causing the moving block to move laterally away from the connecting rod. When the slot on the side of the moving block aligns with the locking block, the locking block enters the slot on the side of the moving block under the action of the clamping spring, thus limiting the position of the moving block and the position of the connecting rod.
[0025] S4. When disassembly is required, first rotate the pull rod to rotate the blocking rod. Then pull the pull block to pull out the pull rod. Then pull out the locking block and make the locking block leave the locking groove on the side of the moving block. Then the short plate and the long plate can be separated.
[0026] S5. When the long plate and the short plate are spliced together, the buffer rod will enter the interior of the connecting rod when the connecting rod moves relative to the short plate. At this time, the buffer block will slide against the circular groove under the action of the buffer spring. Part of the force of the relative motion is converted into the force of the repeated vibration of the buffer spring and most of it is used to overcome the sliding friction between the buffer block and the circular groove.
[0027] S6. At this point, the installation of the prefabricated house is completed by fixing the roof to the top sides of the two short and long boards with bolts.
[0028] Compared with the prior art, the present invention provides a prefabricated folding house and a construction method, which has the following beneficial effects:
[0029] 1. The prefabricated folding house and its construction method allow for the rapid splicing of long and short planks using a connecting device. This splicing device is stable and not easily loosened. No additional tools are required during installation and disassembly, which greatly saves labor time and the use of additional tools, thus significantly improving the construction efficiency of the prefabricated folding house during installation and disassembly.
[0030] 2. The prefabricated folding house and its construction method can reduce the collision force between long and short boards during assembly through a buffer device. Even when spliced by hoisting, the short and long boards will not be damaged due to the large contact force between them.
[0031] 3. The prefabricated folding house and its construction method require the pull block to be rotated during disassembly to release the limiting device of the connecting device, which avoids the accidental loosening of the connection between the long board and the short board caused by the indoor occupants accidentally pulling the pull block and at that moment a large lateral force.
[0032] 4. During transportation, the long boards of this prefabricated folding house and its construction method can be folded by the folding mechanism, making the long boards easier to transport. This avoids the need for larger trucks due to the excessive length of the long boards, thus reducing the transportation cost of the prefabricated folding house. Attached Figure Description

[0041] like Figure 1-7As shown, the present invention provides a technical solution: a prefabricated folding house, comprising: a long board 1, the side of the long board 1 being movably connected to the side of a short board 2, the top side of the long board 1 being movably connected to the bottom side of a roof 3 by bolts, a connecting device 4 being provided on the side of the long board 1, the connecting device 4 comprising: a connecting rod 401 and a blocking rod 409, the top side of the connecting rod 401 being fixedly connected to the side of the long board 1, the side of the connecting rod 401 being hinged to one end of an upper short rod 402, and the other end of the upper short rod 402 being connected to a lower short rod 403. One end is hinged, and the other end of the lower short rod 403 is hinged to the side of the square ring 405. The hinge point between the upper short rod 402 and the lower short rod 403 is hinged to the side of the moving block 404. The inner wall of the square ring 405 is slidably connected to the outer wall of the connecting rod 401. The slotted part on the side of the moving block 404 is engaged with the outer wall of the locking block 406. The side of the locking block 406 is fixedly connected to one end of the clamping spring 407. The other end of the clamping spring 407 is fixedly connected to the inside of the short plate 2. The side of the locking block 406 is rotated with one end of the pull rod 408. The connecting rod 409 is fixedly connected to the outer wall of the connecting rod 408. A buffer device 5 is installed inside the short plate 2. The buffer device 5 includes: a buffer rod 501, the bottom of which is fixedly connected to the inside of the short plate 2; one end of a buffer spring 502 is fixedly connected to the inside of the buffer rod 501; the other end of the buffer spring 502 is fixedly connected to one end of a buffer block 503; and the other end of the buffer block 503 fits into the inside of a circular groove 504, which is located inside the connecting rod 401. The long plate... The interior of plate 1 is equipped with a folding mechanism 6, which includes a semi-arc rod 601. One end of the semi-arc rod 601 is fixedly connected to the interior of the long plate 1. The groove on the side of the semi-arc rod 601 is engaged with the outer wall of the limiting block 602. The side of the limiting block 602 is fixedly connected to one end of the limiting spring 603. The other end of the limiting spring 603 is fixedly connected to the interior of the long plate 1. The side of the limiting block 602 is fixedly connected to one end of the L rod 604. The middle outer wall of the long plate 1 is fixedly connected to the side of the hinge 606 by bolts.
[0042] In one embodiment of the present invention, to make the pull rod 408 easier to pull, the other end of the pull rod 408 is fixedly connected to the side of the pull block 410. To make the L rod 604 easier to move, the other end of the L rod 604 is fixedly connected to the side of the moving block 605. To make the moving block 404 easier to move laterally, the number of upper short rods 402 and lower short rods 403 in the connecting device 4 is set to two sets, and the two sets are symmetrically distributed on both sides of the moving block 404. To improve the lateral limiting effect of the moving block 404, the number of upper short rods 402, lower short rods 403, moving block 404, locking block 406, clamping spring 407, pull rod 408, and blocking rod 409 in the connecting device 4 is set to two sets, and the two sets of upper short rods 402 and lower short rods 403 are fixedly connected to the side of the moving block 605. Short rod 403, moving block 404, locking block 406, clamping spring 407, pull rod 408, and blocking rod 409 are symmetrically distributed on both sides of connecting rod 401. To improve the connection between long plate 1 and short plate 2, the number of connecting devices 4 is set to four sets, and the four sets of connecting devices 4 are symmetrically distributed in pairs on both sides of short plate 2. Each pair of connecting devices 4 is symmetrically distributed vertically on the side of short plate 2. To make the folding effect of long plate 1 more stable, the number of hinges 606 is set to two sets, and the two sets of hinges 606 are symmetrically distributed in the middle of the side of long plate 1. To allow the house to be entered, a door frame is opened inside one set of short plate 2. To give the roof a certain drainage function, the top of the roof 3 is set to be triangular.
[0043] A building construction method includes the following steps:
[0044] S1. When it is necessary to install the folding house, the foundation should be leveled first to make the ground flat and a cement floor should be laid.
[0045] S2. Unfold the folded long board 1 so that half of the long board 1 opens around the hinge 606. At this time, the semi-arc rod 601 inside one half of the long board 1 enters the arc groove inside the other half of the long board 1. When the long board 1 reaches the horizontal position, under the action of the limiting spring 603, the locking block 406 enters the side locking groove of the semi-arc rod 601. If the long board 1 needs to be transported again, it needs to be folded. Push the moving block 605 to the left so that the L rod 604 moves to the left and drives the limiting block 602 away from the side locking groove of the semi-arc rod 601. At this time, one half of the long board 1 can be rotated around the hinge 606 and the long board 1 can be folded. The long board 1 is folded by the folding mechanism 6, making the long board 1 easier to transport. This avoids the need for a large truck due to the long board 1 being too long, thus reducing the transportation cost of the prefabricated folding house.
[0046] S3. After the long plate 1 is unfolded, align the connecting rod 401 on the side of the long plate 1 with the opening of the short plate 2 and begin assembly. At this time, the square ring 405 touches the protrusion inside the short plate 2, while the connecting rod 401 can continue to move. The square ring 405 moves upward relative to the connecting rod 401, which drives the upper and lower short rods 403 and the upper short rod 402 to rotate in opposite directions, causing the moving block 404 to move laterally away from the connecting rod 401. When the slot on the side of the moving block 404 is aligned with the locking block 406... Under the action of the clamping spring 407, the locking block 406 enters the locking groove on the side of the moving block 404, thus limiting the position of the moving block 404 and the position of the connecting rod 401. The long plate and the short plate 2 are quickly spliced by the connecting device 4. The connecting device 4 has good stability and is not easy to loosen. No additional tools are needed during installation and disassembly, which greatly saves labor time and the use of additional tools, thus greatly improving the construction efficiency of the prefabricated folding house during construction, installation and disassembly.
[0047] S4. When disassembly is required, first rotate the pull rod 408 to rotate the blocking rod 409. Then, pull the pull block 410 to pull out the pull rod 408. Then, pull out the locking block 406 and make the locking block 406 leave the locking groove on the side of the moving block 404. Then, the short plate 2 and the long plate 1 can be separated. When disassembling, the pull block 410 needs to be rotated to release the limiting device 4. This avoids the accident where the occupants of the room accidentally pull the pull block 410 and there happens to be a large lateral force, which causes the connection between the long plate 1 and the short plate 2 to become loose.
[0048] S5. When the long plate 1 and the short plate 2 are spliced together, when the connecting rod 401 moves relative to the short plate 2, the buffer rod 501 will enter the interior of the connecting rod 401. At this time, the buffer rod 501 is pressed against the circular groove 504 and slides relative to it under the action of the buffer spring 502. Part of the force of the relative movement is converted into the force of the repeated vibration of the buffer spring 502 and most of it is used to overcome the sliding friction between the buffer block 503 and the circular groove 504. The collision force between the long plate 1 and the short plate 2 is reduced by the buffer device 5. Even if spliced by hoisting, the short plate 2 and the long plate 1 will not be damaged due to the large contact force between them.
[0049] S6. At this point, the installation of the prefabricated house can be completed by fixing the roof 3 to the top sides of the two short boards 2 and the long board 1 with bolts.
[0050] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
