Description

Technical Field

[0001] This application relates to the field of housing construction, and in particular to a prefabricated assembled house. Background Technology

[0002] Prefabricated construction refers to the transfer of a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. For example, a prefabricated balcony consists of several major components and accessories, which can be directly installed on-site.

[0003] The traditional installation process for prefabricated balconies is roughly as follows: first, the prefabricated balcony is hoisted to the designated height of the house using a crane; then, the prefabricated balcony is placed in the balcony construction area; next, the prefabricated balcony is tied and fixed to the balcony construction area with steel bars; and finally, concrete is poured to completely fix the balcony to the balcony construction area.

[0004] After the crane boom lifts the finished balcony to the designated height, the boom cannot directly deliver the balcony to the designated balcony construction area due to the influence of the building's exterior walls. At this point, the balcony can only be dragged to the construction area manually using tools such as poles. However, during the dragging process, the balcony may inevitably shift or rotate. In this case, the balcony's position must be continuously adjusted and corrected manually. The entire adjustment process is time-consuming and laborious, causing great inconvenience to the balcony installation work. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a prefabricated assembled house.

[0006] This application provides a prefabricated assembled house, which adopts the following technical solution:

[0007] A prefabricated assembled house includes an assembly panel for assembling the house and a prefabricated balcony for mounting on the assembly panel. An assembly platform is provided on one side of the assembly panel, and a sliding plate is slidably mounted on the assembly platform. A guide sleeve with a central axis along the sliding direction of the sliding plate is provided on the assembly panel. A sliding rod is provided on the side wall of the sliding plate facing the guide sleeve and inserted into and sliding within the guide sleeve. A plurality of positioning tubes are provided on the sliding plate, and the positioning tubes are perpendicular to the sliding plate. A plurality of positioning slots for inserting the positioning tubes are provided on the prefabricated balcony.

[0008] By adopting the above technical solution, after the crane arm delivers the prefabricated balcony to the designated height, the sliding plate is first slid away from the assembly platform until it is moved below the prefabricated balcony. During this sliding, the sliding rod gradually extends from the guide sleeve, and the cooperation between the guide sleeve and the sliding rod limits the maximum sliding distance of the sliding plate and guides its movement. Next, the positioning groove on the prefabricated balcony is aligned with the positioning tube on the sliding plate, and the crane arm gradually lowers the prefabricated balcony until the positioning tube and positioning groove are interlocked. This interlocking of the positioning tube and positioning groove initially fixes the prefabricated balcony onto the sliding plate. Then, the sliding plate is pulled closer to the assembly platform, and the prefabricated balcony is successfully moved into the designated balcony construction area. Workers no longer need to adjust the position of the prefabricated balcony, making the entire process time-saving and labor-saving, significantly reducing the workload and improving the installation efficiency of the prefabricated balcony.

[0009] Optionally, a lifting ring is provided on the side wall of the sliding plate facing the guide sleeve, and a slot for inserting the lifting ring is provided on the assembly plate, the slot being located on the sliding path of the lifting ring.

[0010] By adopting the above technical solution, when the sliding plate needs to be slid, the worker can use a long rod with hooks at the ends to hook into the lifting rings, thus enabling the sliding plate to slide back and forth. Throughout the entire operation, the worker can stand in the safe area of ​​the building, effectively preventing the worker from falling due to standing too far forward, and ensuring the safety of the worker during operation. When the sliding plate is moved closer to the assembly plate, the lifting rings will finally be inserted into their respective slots. The slots can hide the lifting rings, thereby ensuring the tightness of the final joint between the sliding plate and the assembly plate.

[0011] Optionally, the assembly plate is provided with a pin hole communicating with the slot, and a positioning pin is movably inserted into the pin hole. The direction in which the positioning pin is inserted into the pin hole is perpendicular to the direction in which the lifting ring is inserted into the slot. The positioning pin is used to be inserted into the lifting ring.

[0012] By adopting the above technical solution, before moving the sliding plate closer to the assembly plate, the positioning pin is first removed from the pin hole; after the lifting ring is inserted into the slot, the positioning pin is reinserted into the pin hole. Since the pin hole and the slot are interconnected, the positioning pin will eventually be inserted into the lifting ring. Through the mutual insertion and cooperation of the positioning pin and the lifting ring, the movement of the sliding plate away from the assembly plate can be restricted, thus achieving the initial fixation of the sliding plate. The entire fixing process is convenient and quick to operate.

[0013] Optionally, the assembly plate is also provided with a number of insertion tubes, the length of which extends along the sliding direction of the sliding plate; the prefabricated balcony is provided with insertion holes corresponding to the insertion tubes, the insertion holes being used for inserting the respective insertion tubes into the prefabricated balcony.

[0014] By adopting the above technical solution, when the sliding plate is moved closer to the assembly plate, the insertion tubes will eventually be gradually inserted into their respective insertion holes. Through the mutual insertion and cooperation of the insertion tubes and insertion holes, the prefabricated balcony can be effectively prevented from detaching from the sliding plate in the vertical direction. Finally, the assembly plate, the sliding plate and the prefabricated balcony are interconnected, which further enhances the limiting and fixing of the prefabricated balcony and ensures the stability and reliability of the prefabricated balcony on the sliding plate.

[0015] Optionally, the insertion hole is connected to the corresponding positioning groove, and the outer wall of the positioning tube is provided with an insertion hole for inserting the insertion tube into the positioning tube.

[0016] By adopting the above technical solution, as the insertion tubes are gradually inserted into their respective corresponding insertion holes, the ends of the insertion tubes will eventually be inserted into the insertion holes of their respective communicating positioning tubes. Through the mutual insertion and cooperation of the insertion tubes and positioning tubes, the insertion and cooperation between the sliding plate and the assembly plate can be realized, making the sliding plate more stable and reliable in limiting its position on the assembly platform, further preventing the sliding plate from detaching from the assembly platform in the vertical direction; at the same time, it can also further enhance the reliability of the connection between the prefabricated balcony and the sliding plate.

[0017] Optionally, one end of the insertion tube away from the assembly platform extends to the outer wall of the assembly plate, and a grouting hole is formed at the end of the insertion tube after it extends out of the assembly plate. A grout outlet hole communicating with the grouting hole is formed at the other end of the insertion tube.

[0018] By adopting the above technical solution, after the insertion tube and the positioning tube are connected to each other, concrete grout is injected into the grouting hole at one end of the insertion tube. The concrete grout will eventually be continuously injected into the positioning tube from the grout outlet hole of the insertion tube. By pouring concrete grout into the positioning tube, the reliability of the connection between the precast balcony and the sliding plate can be ensured after the concrete solidifies. This effectively prevents the separation of the two joints and ensures the safety and firmness of the precast balcony after installation.

[0019] Optionally, the outer wall of the sliding plate is provided with limiting plates located on both sides of the sliding plate, and the outer wall of the prefabricated balcony is provided with limiting grooves for the insertion of the limiting plates, and the limiting grooves are symmetrically arranged on both sides of the prefabricated balcony.

[0020] By adopting the above technical solution, when assembling a prefabricated balcony onto a sliding plate, workers often cannot easily observe the position of the positioning groove at the bottom of the prefabricated balcony. Therefore, to ensure that the positioning tube can be accurately inserted into the positioning groove at the bottom of the prefabricated balcony, during the hoisting of the prefabricated balcony, workers can easily determine whether the positioning tube is aligned with the positioning groove by judging whether the position of the limiting plate is aligned with the limiting groove on both sides of the prefabricated balcony. Finally, the limiting plates are inserted into their respective corresponding limiting grooves. Through the mutual insertion of the limiting plates and limiting grooves, the positioning tube can be successfully inserted into its respective corresponding positioning groove, thus facilitating the hoisting work of the workers.

[0021] Optionally, a protective plate is formed on the assembly platform, and the protective plate is symmetrically arranged on both sides of the sliding plate; the protective plate and the sliding plate are in close contact with each other, and the length of the protective plate extends along the sliding direction of the sliding plate.

[0022] By adopting the above technical solution, the protective plates located on both sides of the sliding plate can limit and guide the sliding of the sliding plate, thereby effectively preventing the sliding plate from falling off the sides of the assembly platform during the sliding process. In addition, it can also ensure the stability of the sliding plate during the sliding process and prevent unnecessary deviation of the sliding plate during the sliding process.

[0023] A construction method for prefabricated assembled houses, applied to the aforementioned prefabricated assembled houses, includes:

[0024] S1. Hoisting the prefabricated balcony: Using a hoisting device, the prefabricated balcony is hoisted to the designated height;

[0025] S2. Place the prefabricated balcony, move the sliding plate away from the assembly platform until the sliding plate is pushed under the prefabricated balcony; then place the prefabricated balcony on the sliding plate, and ensure that the positioning tubes are inserted into their respective positioning slots.

[0026] S3. Position the prefabricated balcony by moving the sliding plate on which the prefabricated balcony is placed towards the assembly plate until the insertion tube is fully inserted into the insertion hole; then insert the positioning pin into the lifting ring to complete the positioning of the prefabricated balcony.

[0027] S4. Pour concrete into the grouting hole, and finally use the concrete to cast the assembly plate and the surface of the precast balcony.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] Workers no longer need to adjust the position of the prefabricated balcony, saving time and effort throughout the process, greatly reducing the workload of workers and improving the installation efficiency of the prefabricated balcony.

[0030] Throughout the entire operation, workers can remain within the safe area of ​​the building, effectively preventing workers from falling due to standing too close to the front and ensuring their safety during operation.

[0031] Ensuring the reliability of the connection between the prefabricated balcony and the sliding plate effectively prevents separation at the joint, thus guaranteeing the safety and stability of the prefabricated balcony after installation. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0039] This application discloses a prefabricated assembled house. (Refer to...) Figure 1 The prefabricated modular house includes a prefabricated panel 1 for assembling the house and a prefabricated balcony 2 for installing on the prefabricated panel 1. During construction, the prefabricated panel 1 is laid horizontally in the designated installation area of ​​the building. One side of the prefabricated panel 1 is integrally formed with concrete to form an assembly platform 3. There is a height difference between the upper surface of the assembly platform 3 and the upper surface of the prefabricated panel 1, and the height of the upper surface of the assembly platform 3 is lower than the height of the upper surface of the prefabricated panel 1.

[0040] like Figure 2 , Figure 3As shown, a sliding plate 4 is slidably mounted on the assembly platform 3 in a horizontal direction. Multiple horizontally placed guide sleeves 10 are installed inside the assembly plate 1, with the central axis of each guide sleeve 10 aligned with the sliding direction of the sliding plate 4 on the assembly platform 3. The guide sleeves 10 are hollow inside, and adjacent guide sleeves 10 are arranged at intervals. A number of sliding rods 40, corresponding to the number of guide sleeves 10, are fixedly mounted on the outer wall of the sliding plate 4 facing the guide sleeves 10. The positions of the sliding rods 40 correspond one-to-one with the positions of the guide sleeves 10. The end of each sliding rod 40 away from the sliding plate 4 is inserted into and slides within its corresponding guide sleeve 10. The sliding rod 40 and the guide sleeve 10 are coaxially aligned, and the end of the sliding rod 40 away from the sliding plate 4 is confined within the guide sleeve 10, preventing the sliding rod 40 from completely detaching from the guide sleeve 10.

[0041] like Figure 2 , Figure 3 As shown, two protective plates 30 are fixedly installed on the outer wall of the upper surface of the assembly platform 3. The protective plates 30 are symmetrically arranged on the left and right sides of the sliding plate 4, and the protective plates 30 are in close contact with the outer wall of the sliding plate 4. The length of the protective plates 30 extends along the sliding direction of the sliding plate 4. The protective plates 30 located on the left and right sides of the sliding plate 4 can limit and guide the sliding of the sliding plate 4. This can effectively prevent the sliding plate 4 from falling off the left and right sides of the assembly platform 3 during the sliding process. In addition, it can also ensure the stability of the sliding plate 4 when sliding on the assembly platform 3 and prevent unnecessary displacement of the sliding plate 4 during the sliding process.

[0042] like Figure 4 , Figure 5 As shown, multiple sets of hollow positioning tubes 41 are fixedly installed on the upper surface of the sliding plate 4, and the positioning tubes 41 are perpendicular to the upper surface of the sliding plate 4. The number of positioning tubes 41 can be increased or decreased according to actual needs. In this embodiment, three sets of positioning tubes 41 are used as an example. The three sets of positioning tubes 41 are arranged sequentially at intervals along the sliding direction of the sliding plate 4, and the positioning tubes 41 in the same group are arranged sequentially at intervals along the sliding direction perpendicular to the sliding plate 4. The positioning tubes 41 in adjacent groups are staggered.

[0043] like Figure 4 , Figure 5 As shown, the bottom of the prefabricated balcony 2 is provided with several positioning grooves 20 that correspond one-to-one with the positions of the positioning tubes 41 on the sliding plate 4. The positioning grooves 20 are used to allow the corresponding positioning tubes 41 to be inserted into the prefabricated balcony 2 from bottom to top.

[0044] like Figure 3 , Figure 5As shown, a plurality of lifting rings 42 are fixedly installed on the outer wall of the sliding plate 4 facing the guide sleeve 10. The lifting rings 42 are arranged sequentially at intervals on the sliding plate 4 along a sliding direction perpendicular to the sliding plate 4. The outer wall of the assembly plate 1 facing the lifting rings 42 is provided with a number of slots 11 that are the same as the number of lifting rings 42. The positions of the slots 11 correspond one-to-one with the positions of the lifting rings 42. The slots 11 are used for inserting their respective lifting rings 42 into the assembly plate 1, and the slots 11 are located on the sliding path of their respective lifting rings 42.

[0045] like Figure 3 , Figure 5 As shown, the upper surface of the assembly plate 1 has a number of pin holes 12 that match the number of slots 11, and the positions of the pin holes 12 correspond one-to-one with the positions of the slots 11. The pin holes 12 communicate with their respective slots 11 along the thickness direction of the assembly plate 1. A positioning pin 13 is movably inserted into each pin hole 12, and the direction in which the positioning pin 13 is inserted into the pin hole 12 is perpendicular to the direction in which the lifting ring 42 is inserted into the slot 11. The positioning pin 13 can be inserted from top to bottom onto its respective lifting ring 42.

[0046] Before moving the sliding plate 4 towards the mounting plate 1, remove the locating pin 13 from the pin hole 12. After the lifting rings 42 are inserted into their respective slots 11, reinsert the locating pin 13 into the pin hole 12. Since the pin hole 12 and the slot 11 are interconnected, the lower end of the locating pin 13 will eventually be inserted into the slot 11 and engage with the lifting rings 42. Through the engagement of the locating pin 13 and the lifting rings 42, the movement of the sliding plate 4 away from the mounting plate 1 can be initially restricted, preventing accidents. The entire fixing process is convenient and quick.

[0047] like Figure 2 , Figure 4 As shown, two parallel limiting plates 43 are integrally formed on the outer wall of the upper surface of the sliding plate 4. The limiting plates 43 are perpendicular to the upper surface of the sliding plate 4 and are symmetrically arranged on the left and right sides of the sliding plate 4. Two limiting grooves 22 are provided on the outer wall of the prefabricated balcony 2 for inserting the opposing limiting plates 43. The limiting grooves 22 are symmetrically arranged on the left and right sides of the prefabricated balcony 2. The shape of the limiting plate 43 matches the shape of the limiting groove 22.

[0048] When assembling the prefabricated balcony 2 onto the sliding plate 4, workers cannot directly observe the position of the positioning groove 20 at the bottom of the prefabricated balcony 2. Therefore, to ensure that the positioning tube 41 can be accurately inserted into the positioning groove 20 at the bottom of the prefabricated balcony 2, during the hoisting of the prefabricated balcony 2, workers can easily determine whether the positioning tube 41 is aligned with the positioning groove 20 by checking whether the position of the limiting plate 43 is aligned with the limiting groove 22 on both sides of the prefabricated balcony 2. Finally, the limiting plates 43 are inserted into their respective corresponding limiting grooves 22. Through the mutual insertion of the limiting plates 43 and the limiting grooves 22, the positioning tube 41 is successfully inserted into its respective corresponding positioning groove 20, thus facilitating the hoisting work of the workers.

[0049] like Figure 3 , Figure 4 As shown, several hollow insert tubes 14 are fixedly installed on the outer wall of the assembly plate 1 facing the sliding plate 4. The number of insert tubes 14 is the same as the number of positioning tubes 41. One end of the insert tube 14 protrudes from the outer wall of the assembly plate 1 facing the sliding plate 4, and the insert tube 14 extends along the sliding direction of the sliding plate 4 after protruding from the outer wall of the assembly plate 1. The end of the insert tube 14 away from the sliding plate 4 protrudes from the outer wall of the upper surface of the assembly plate 1, and a grouting hole 140 is formed at the end of the insert tube 14 after protruding. A grout outlet hole 141 communicating with the grouting hole 140 is formed at the other end of the insert tube 14.

[0050] like Figure 3 , Figure 4 As shown, the outer wall of the prefabricated balcony 2 facing the assembly plate 1 is also provided with insertion holes 21 corresponding to the positions of the insertion tubes 14. The insertion holes 21 are used to allow the corresponding insertion tubes 14 to be horizontally inserted into the prefabricated balcony 2 along the sliding direction of the sliding plate 4. The end of the insertion hole 21 away from the assembly plate 1 is connected to the corresponding positioning groove 20. The length of the insertion tube 14 is matched according to the depth of the corresponding insertion hole 21. The outer wall of the positioning tube 41 is provided with a insertion hole 410, which is connected to the inside of the positioning tube 41. When the positioning tube 41 is fully inserted into the positioning groove 20, the insertion hole 410 will be directly opposite and connected to the insertion hole 21. The insertion hole 410 is used to allow the end of the insertion tube 14 to be inserted into the positioning tube 41 along the sliding direction of the sliding plate 4.

[0051] After the prefabricated balcony 2 is assembled onto the sliding plate 4, the sliding plate 4 is moved closer to the assembly plate 1. At this time, the insertion tube 14 will be gradually inserted into the corresponding insertion hole 21. Through the mutual insertion and cooperation of the insertion tube 14 and the insertion hole 21, the prefabricated balcony 2 can be effectively prevented from detaching from the sliding plate 4 in the vertical direction.

[0052] As the insertion tubes 14 are gradually inserted into their respective corresponding insertion holes 21, the ends of the insertion tubes 14 will eventually be inserted into the insertion holes 410 of their respective communicating positioning tubes 41. Through the mutual insertion and cooperation of the insertion tubes 14 and the positioning tubes 41, the sliding plate 4 and the assembly plate 1 can be connected, making the sliding plate 4 more stable and securely limited on the assembly platform 3, further preventing the sliding plate 4 from detaching from the assembly platform 3 in the vertical direction. At the same time, it can also further enhance the connection reliability between the prefabricated balcony 2 and the sliding plate 4.

[0053] After the insertion tube 14 and the positioning tube 41 are connected, concrete grout is injected into the grouting hole 140 at one end of the insertion tube 14. The concrete grout will eventually be continuously injected into the positioning tube 41 from the grout outlet hole 141 of the insertion tube 14. By pouring concrete grout into the positioning tube 41, the reliability of the connection between the precast balcony 2 and the sliding plate 4 can be ensured after the concrete solidifies. This effectively prevents the separation of the two joints and ensures the safety and firmness of the precast balcony 2 after installation.

[0054] On the other hand, this application also provides a construction method for prefabricated assembled houses, applied to the aforementioned prefabricated assembled houses, including:

[0055] S1. Hoist the prefabricated balcony 2, using a hoisting device to hoist the prefabricated balcony 2 to the designated height;

[0056] S2. Place the prefabricated balcony 2, move the sliding plate 4 away from the assembly platform 3 until the sliding plate 4 is pushed under the prefabricated balcony 2; then place the prefabricated balcony 2 on the sliding plate 4, and ensure that the positioning tube 41 is inserted into its corresponding positioning groove 20.

[0057] S3. Position the prefabricated balcony 2 by moving the sliding plate 4 on which the prefabricated balcony 2 is placed towards the assembly plate 1 until the insertion tube 14 is fully inserted into the insertion hole 21; then insert the positioning pin 13 into the lifting ring 42 to complete the positioning of the prefabricated balcony 2.

[0058] S4. Pour concrete into the grouting hole 140, and finally use the concrete to pour the assembly plate 1 and the surface of the precast balcony 2.

[0059] The implementation principle of a prefabricated assembled house according to an embodiment of this application is as follows: After the crane arm sends the prefabricated balcony 2 to a designated height, the sliding plate 4 is first slid away from the assembly platform 3 until it is moved below the prefabricated balcony 2. During the sliding of the sliding plate 4, the sliding rod 40 gradually extends from the guide sleeve 10. Through the cooperation between the guide sleeve 10 and the sliding rod 40, the maximum sliding distance of the sliding plate 4 is limited, and the sliding of the sliding plate 4 is guided. Next, the positioning groove 20 on the prefabricated balcony 2 is aligned with the positioning tube 41 on the sliding plate 4. Then, the prefabricated balcony 2 is gradually lowered by the crane arm until the positioning tube 41 and the positioning groove 20 are interlocked and positioned. Through the interlocking of the positioning tube 41 and the positioning groove 20, the prefabricated balcony 2 is initially fixed on the sliding plate 4. Next, the sliding plate 4 is pulled towards the assembly platform 2, at which point the prefabricated balcony 2 is smoothly moved into the designated balcony construction area. Workers no longer need to adjust the position of the prefabricated balcony 2, saving time and effort throughout the process, greatly reducing the workload of workers and improving the installation efficiency of the prefabricated balcony 2.

[0060] 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.
