Abstract
Description
Technical Field
[0001] This utility model belongs to the field of prefabricated building technology, and in particular relates to a prefabricated building wall panel. Background Technology
[0002] With the continuous improvement of the level of industrialization in the construction industry, prefabricated buildings, as an efficient, environmentally friendly, and energy-saving construction method, have been widely promoted and applied globally. Among them, prefabricated wall panels, as a key component in prefabricated buildings, undertake multiple functions such as load-bearing, enclosure, thermal insulation, and sound insulation. The design of their structural form and connection method directly affects the overall performance of the building structure and construction efficiency.
[0003] Prefabricated wall panels typically refer to wall components that are prefabricated in a factory and then assembled into a complete building structure through splicing and connection methods at the construction site. Based on material type, prefabricated wall panels can be divided into reinforced concrete solid wall panels, hollow wall panels, composite insulation wall panels, lightweight aggregate concrete panels, and new environmentally friendly material wall panels, etc. Based on connection method, they can be divided into dry connection and wet connection. Dry connection is widely used in modern construction due to its advantages such as ease of disassembly and assembly, low pollution, and fast construction.
[0004] In existing technologies, the most common method for connecting prefabricated wall panels is bolt connection. For example, in the technical solution with announcement number CN221627297U, multiple sets of bolts are used to fasten adjacent wall panels to achieve structural stability and assembly reliability. Although this type of solution has good mechanical properties, it also suffers from low construction efficiency. Bolt connection requires aligning the holes, inserting the bolts, and tightening the nuts on-site, and the entire operation requires the use of tools. The operation steps are cumbersome, time-consuming, and labor-intensive, which cannot effectively meet the requirements of rapid construction in modern industrialized buildings. Utility Model Content

[0027] Combination Figures 1 to 6 This invention describes an embodiment of a prefabricated building wall panel, comprising:
[0028] Main wall panel 10, comprising, in sequence, a first side panel, a second side panel, a third side panel, and a fourth side panel; combined with Figure 2 The first side of the wall panel is provided with a wall panel insert 11, and the third side of the wall panel is provided with a wall panel slot 12. The first side and the third side of the wall panel are positioned opposite each other, and the wall panel insert 11 and the wall panel slot 12 are aligned with each other.
[0029] The substrate 20 includes a first side, a second side, a third side, and a fourth side. For ease of description, in this embodiment, the positions of each side of the substrate and each side of the main wall panel correspond. The substrate 20 is connected to the back of the main wall panel 10, and the front of the main wall panel is the side that the user can see after construction. The second side of the substrate is provided with a substrate slot 22, and the substrate 20 is also provided with a second limiting groove 24 that communicates with the substrate slot 22. Figure 3 This is a schematic cross-sectional view of the substrate according to an embodiment of the present invention. Figure 3 It can display the detailed structure located within the substrate. Figure 3 The image shows a large substrate slot 22, due to Figure 1 In a non-sectional view, a second limiting groove 24 is provided at a position corresponding to the substrate slot 22, and the second limiting groove extends from the side of the substrate to the substrate slot; a second locking device 40 is provided on the fourth side of the substrate; the second side of the substrate coincides with the second side of the wall panel, and the fourth side of the substrate coincides with the fourth side of the wall panel; the second locking device 40 includes a substrate insert 41, which is adapted to the substrate slot 22; a insert mounting groove 45 is provided on one side of the substrate insert 41, and a second limiting block 42 is installed in the insert mounting groove 45. A second spring 44 is also installed in the insert mounting groove 45, and the second spring 44 pushes the second limiting block 42 into the second limiting groove 24 of the substrate 20.
[0030] The following describes the usage process of this prefabricated building wall panel. When assembling the wall panels, first insert the wall panel insert from the right-side prefabricated wall panel into the wall panel slot on the left-side prefabricated wall panel, and continue assembling the wall panels at that height. When assembling upwards, first align the base plate slot of the upper prefabricated wall panel with the second locking device (manually press down the second limiting block) of the lower prefabricated wall panel, allowing the base plate insert to gradually insert into the base plate slot. When the second limiting block slides to the position corresponding to the second limiting groove, the second limiting block is pushed into the second limiting groove by the elastic force of the second spring. Furthermore, through the through-type second limiting groove, when disassembling adjacent wall panels, use a tool to press down the second limiting block, causing the second spring to compress and contract. When the second limiting block is completely disengaged from the second limiting groove, pull the base plate insert outwards, gradually moving the base plate insert of one wall panel out of the base plate slot of the adjacent wall panel.
[0031] In a preferred embodiment of prefabricated building wall panels, such as Figure 5As shown, the second limiting block 42 is a cylindrical structure, and a retaining ring 43 is provided on the outer side of the second limiting block 42. The retaining ring 43 stops the second limiting block 42 in the insert mounting groove 45. That is to say, the insert mounting groove is also preferably designed as a cylindrical structure, and the inner diameter of the top of the insert mounting groove is smaller than the outer diameter of the retaining ring. In this way, the end of the second limiting block extends out of the insert mounting groove, but the second limiting block will not fall off due to the setting of the retaining ring.
[0032] In a preferred embodiment of a prefabricated building wall panel, the number of substrate slots 22 is two or three, as shown in... Figure 1 and Figure 3 In a preferred embodiment shown, there are two substrate slots 22, which are spaced apart. The number of second locking devices 40 is equal to the number of substrate slots 22, and the position of each second locking device 40 matches the position of the corresponding substrate slot 22. By providing two or more substrate slots and second locking devices, it is possible to avoid large connection wobbling displacement when only one set is provided, and it is also possible to improve the reliability of the connection between the two wall panels and avoid connection failure.
[0033] In a preferred embodiment of a prefabricated building wall panel, the number of wall panel inserts 11 is one to three, and the number of wall panel slots 12 is equal to the number of wall panel inserts 11. The position of each wall panel insert 11 matches the position of the corresponding wall panel slot 12. Figure 1 In one specific embodiment shown, the number of wall panel inserts and wall panel slots is one.
[0034] Because the wall panel inserts and wall panel slots are connected by a plug-in method, they offer the advantage of quick installation and positioning. However, since the wall panels are not mechanically locked together after connection, there is a risk of them falling off. Further improvements are made to the above embodiment: Figure 3 and Figure 4 As shown, the first side of the substrate is provided with a second mounting groove 23; it also includes a first locking device 30, which is disposed in the second mounting groove 23; the third side of the substrate is provided with a first mounting groove 21. Since the first mounting groove is through-type in the third side of the substrate, the operation of the component disposed in the first mounting groove can be realized in the third side of the substrate; the first mounting groove 21 is provided with a mounting block 50 that locks with the first locking device 30. The first locking device 30 includes a telescopic inner core, which is installed in the second mounting groove 23. The end of the telescopic inner core is connected to a first limiting block 33. A first spring 35 is sleeved on the outside of the telescopic inner core. One end of the first spring 35 is connected to the substrate 20, and the other end of the first spring is connected to the telescopic inner core or the first limiting block 33; the mounting block 50 includes a through groove 51 that extends from the first side to the second side. The second side of the mounting block 50 is provided with a first limiting groove 52. The structure of the first limiting groove 52 is adapted to the first limiting block 33, and the first limiting block 33 can pass through the through groove 51. In the process of Figure 3 When connecting two prefabricated building wall panels placed in opposite directions, move the first limiting block of the prefabricated building wall panel located on the right side so that the first limiting block passes through the through groove of the mounting block, and then rotate the first limiting block so that it is locked into the first limiting groove. At this time, the first spring is stretched, and the first spring tightens the first limiting block so that it will not come out of the first limiting groove.
[0035] In a preferred embodiment, the telescopic inner core includes an outer cylinder 31 and an inner rod 32. The inner rod 32 telescopically moves within the outer cylinder 31, and its end is connected to a first limiting block 33. The outer cylinder 31 is connected to the base plate 20. It should be noted that the ends of the outer cylinder and the inner rod have anti-detachment structures to prevent the inner rod from detaching from the outer cylinder when moving within it. For example, a retaining ring is provided at the end of the outer cylinder, and a stop block is provided on the outer wall of the inner rod. The inner rod can pass through the retaining ring, but the stop block will be stopped by the retaining ring. In a preferred embodiment, the first locking device 30 also includes a handle 34, which is installed on the outside of the first limiting block 33. In a preferred embodiment, the handle is a "[" shaped structure made of a metal rod, and the length of the handle is smaller than the through slot.
[0036] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
