Description
Technical Field
[0001] This invention belongs to the field of prefabricated building technology, and particularly relates to a modular prefabricated building splicing structure. Background Technology
[0002] Prefabricated buildings refer to permanent buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured, transported to the construction site, and assembled and installed on-site using reliable connection methods.
[0003] Prefabricated buildings offer advantages such as high energy efficiency, lack of environmental constraints, and low maintenance costs, making them particularly suitable for student apartments in campus environments. Student apartments typically consist of numerous independent rooms, requiring partition walls to separate adjacent rooms. To maintain the integrity of the exterior walls, these partition walls are usually located at the junctions of two sets of exterior walls. However, existing modular prefabricated structures only consider the connection method between two sets of exterior walls. Due to the lack of an effective splicing structure between the two sets of exterior walls and the partition walls, it is impossible to quickly assemble the partition walls at the junctions of the two sets of exterior walls, forcing the use of conventional construction methods such as concrete pouring. This inevitably weakens the advantages of prefabricated buildings, such as high energy efficiency and lack of environmental constraints. Summary of the Invention

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] Reference Figures 1-8 This invention provides a modular prefabricated building assembly structure, including an exterior wall panel 1 and a partition wall panel 2.
[0031] A first connecting block 3 is fixedly connected to one narrow side wall of the exterior wall panel 1, and a connecting groove 5 is provided on the other narrow side wall of the exterior wall panel 1. The first connecting block 3 on one set of exterior wall panels 1 is adapted to the connecting groove 5 on another set of exterior wall panels 1. Vertical connecting groove units are provided on the first connecting block 3 and the connecting groove 5.
[0032] A second connecting block 4 is fixedly connected to a narrow side wall of the partition wall panel 2. The second connecting block 4 is adapted to the vertical connecting groove unit. The partition wall panel 2 is vertically inserted into the side wall of the outer wall panel 1 through the second connecting block 4 and the vertical connecting groove unit.
[0033] The locking assembly is installed inside the outer wall panel 1 and is used for limiting the connection between two adjacent outer wall panels 1 or between two adjacent outer wall panels 1 and a set of partition wall panels 2.
[0034] The main function of the first connecting block 3 and the connecting groove 5 is to effectively connect the two sets of exterior wall panels 1. The main function of the vertical connecting unit is to allow a partition wall panel 2 to connect at the connection point of the two sets of exterior wall panels 1 after the two sets of exterior wall panels 1 are connected. The main function of the second connecting block 4 is to effectively connect the partition wall panel 2 with the two sets of exterior wall panels 1. The main function of the locking component is to form a fixed connection between the two sets of exterior wall panels 1 after they are connected, or to form a fixed connection between the two sets of exterior wall panels 1 and the partition wall panel 2 after they are connected. Overall, the splicing structure of the present invention not only allows for a fixed connection between the two sets of exterior walls, but also allows for the rapid splicing and fixed connection of the partition wall at the connection point of the two sets of exterior walls when a partition wall needs to be installed. This maximizes the advantages of prefabricated buildings, such as efficient construction and freedom from environmental constraints, and is especially suitable for applications in building types such as student dormitories.
[0035] The scheme is further optimized so that the exterior wall panel 1 includes an interior wall surface 14 and an exterior wall surface 17, and the vertical connecting groove unit is set correspondingly to the interior wall surface 14.
[0036] The scheme is further optimized. The vertical connecting groove unit includes a first through groove 6 horizontally opened on the two opposite side walls of the first connecting block 3 and a second through groove 9 opened on the side wall of the connecting groove 5 near the inner wall surface 14. After the first connecting block 3 is connected to the connecting groove 5, the edges of the first through groove 6 and the second through groove 9 overlap. When the two outer wall panels 1 are assembled, after the first through groove 6 and the second through groove 9 are aligned, the second connecting block 4 is inserted into the first through groove 6 and the second through groove 9.
[0037] like Figure 1 and Figure 2 As shown, by aligning the second through groove 9 with the inner wall surface 14, the partition wall panel 2 can be connected to the outer wall panel 1 from one side of the inner wall surface 14, which meets the requirements of construction and use.
[0038] like Figure 5 As shown, the first through groove 6 and the second through groove 9 have the same outline dimensions. After the first connecting block 3 is inserted into the connecting groove 5, the first through groove 6 and the second through groove 9 completely overlap, allowing the second connecting block 4 to smoothly pass into the first through groove 6 and the second through groove 9.
[0039] The locking assembly further optimizes the design by including a sliding cavity 13 within the outer wall panel 1, a linkage plate 22 horizontally slidably connected within the sliding cavity 13, a sliding drive component between the linkage plate 22 and the outer wall panel 1, and a plurality of locking pins 23 fixedly connected to one end of the linkage plate 22 near the connecting groove 5. The locking pins 23 are horizontally arranged. A plurality of second through holes 8 are provided on the side wall of the connecting groove 5 near the linkage plate 22, and a plurality of first through holes 7 are provided on the side wall of the first through groove 6 away from the outer wall panel 1. After the first connecting block 3 is connected to the connecting groove 5, the locking pins 23 sequentially pass through the plurality of second through holes 8 and first through holes 7. A fastener is provided between the locking pins 23 and the first connecting block 3.
[0040] like Figure 5 and Figure 6 As shown, the top and bottom walls of the sliding cavity 13 are respectively provided with sliding grooves 19, and the linkage plate 22 is slidably connected between the two sliding grooves 19. Several second through holes 8 and several first through holes 7 have the same size and height. After the first connecting block 3 is inserted into the connecting groove 5, the second through holes 8 and the first through holes 7 of the same height form a channel. The sliding drive pushes the linkage plate 22 to make the end of the locking pin 23 pass through the channel formed by the second through holes 8 and the first through holes 7 and enter the first through groove 6. As the sliding drive continues to push, the fastener locks the first connecting block 3 in the connecting groove 5.
[0041] In a further optimized design, several fourth through holes 18 are horizontally opened on the two opposite side walls of the second connecting block 4. After the second connecting block 4 passes through the second through groove 9 and the first through groove 6, several locking pins 23 are sequentially inserted into several second through holes 8, fourth through holes 18 and several first through holes 7.
[0042] like Figure 1 and Figure 6 As shown, the dimensions and height of several fourth through holes 18 are consistent with those of the second through holes 8 and the first through holes 7. When it is necessary to connect the partition wall panel 2, firstly, the first connecting block 3 is inserted into the connecting groove 5, and then the second connecting block 4 is inserted into the first through groove 6 and the second through groove 9. The second through holes 8, the first through holes 7 and the fourth through holes 18 form a channel. The end of the locking pin 23 is inserted into the second through holes 8, the first through holes 7 and the fourth through holes 18 in sequence, so as to effectively connect the partition wall panel 2 with the two sets of outer wall panels 1.
[0043] The further optimized solution includes a cavity 12 opened in the first connecting block 3 and two sets of protrusions 24 set at the end of the locking pin 23 away from the linkage plate 22. The cavity 12 is located between the first through groove 6 and the outer wall panel 1. Several third through holes 16 are opened on the side wall of the cavity 12 near the first through groove 6. The two sets of protrusions 24 are slidably connected in the locking pin 23. A spring 25 abuts between the two sets of protrusions 24. After the locking pin 23 passes through the first through groove 6 into the cavity 12, the protrusions 24 are used to lock the locking pin 23 in the cavity 12.
[0044] like Figure 7 As shown, the protrusion 24 has a bevel, which ensures that after the protrusion 24 contacts the edge of the second through hole 8, it can slide smoothly into the locking post 23 under the action of thrust, reducing the difficulty of construction.
[0045] like Figure 6 and Figure 7 As shown, after the partition wall panel 2 and the two sets of outer wall panels 1 are connected, the end of the locking pin 23 passes through the channel formed by the second through hole 8, the first through hole 7 and the fourth through hole 18 and enters the cavity 12. In the channel, the two sets of protrusions 24 are blocked by the inner wall of the channel and retract into the locking pin 23. The spring 25 is in a contracted state. When the protrusions 24 enter the cavity 12 with the end of the locking pin 23, the two sets of protrusions 24 protrude from the locking pin 23 under the elastic force of the spring 25. At this time, the protrusions 24 are attached to the side of the cavity 12 away from the outer wall panel 1, and the linkage plate 22 is attached to the side wall of the sliding cavity 13, so that the first connecting block 3 is fixedly connected in the connecting groove 5, and the two sets of outer wall panels 1 and the one set of partition wall panels 2 are fixedly connected.
[0046] The further optimized scheme includes a sliding drive component comprising a rack 20 horizontally fixedly connected to the side wall of the linkage plate 22 away from the locking post 23 and a gear 21 rotatably connected in the sliding cavity 13. The gear 21 meshes with the rack 20, and a sleeve 15 is detachably connected to one end of the gear 21. The sleeve 15 is used to drive the gear 21 to rotate.
[0047] like Figure 8 As shown, a groove is provided at one end of the shaft of gear 21, and sleeve 15 is inserted into the groove to achieve transmission connection with gear 21.
[0048] like Figure 5 As shown, the on-site operator rotates the sleeve 15 with a tool. The sleeve 15 drives the gear 21 to rotate. When the gear 21 rotates, it pushes the rack 20. By pushing the rack 20, it pushes the linkage plate 22, thereby pushing the locking pin 23 to move.
[0049] The design was further optimized so that sleeve 15 is installed on one side of the inner wall surface 14.
[0050] like Figure 2 As shown, the sleeve 15 is placed on one side of the inner wall 14, which is convenient for on-site personnel to operate.
[0051] The scheme is further optimized by providing several second bolt holes 11 on the first connecting block 3 and several first bolt holes 10 on the two opposite side walls of the connecting groove 5. The several second bolt holes 11 and several first bolt holes 10 are respectively set accordingly, and the second bolt holes 11 and the first bolt holes 10 are connected by bolts.
[0052] like Figure 1 and Figure 5 As shown, after the two sets of exterior wall panels 1 are connected, several second bolt holes 11 and several first bolt holes 10 are aligned respectively. At this time, the on-site personnel can insert bolts between the second bolt holes 11 and the first bolt holes 10 and use nuts to fix the bolts to the exterior wall panels 1. This can play a pre-connection role before the locking post 23 plays a locking role, and can also improve the connection strength between the exterior wall panels 1.
[0053] In a further optimized design, a cover plate (not shown in the figure) is detachably connected to the second through groove 9. When the connection between the two outer wall panels 1 does not require the connection of the inner wall panel 2, the cover plate can be used to seal the second through groove 9 to ensure the integrity of the inner wall surface 14.
[0054] In a further optimized design, an external wall insert 26 is fixedly connected to the top of the external wall panel 1, and an external wall slot 27 is provided at the bottom of the external wall panel 1. The external wall insert 26 and the external wall slot 27 are respectively set perpendicular to the narrow wall surface of the external wall panel 1. The external wall insert 26 and the external wall slot 27 are used to limit the connection between two adjacent external wall panels 1.
[0055] In a further optimized design, a partition wall block 28 is fixedly connected to the top of the partition wall panel 2, and a partition wall slot 29 is provided at the bottom of the partition wall panel 2. The partition wall block 28 and the partition wall slot 29 are respectively set perpendicular to the narrow wall surface of the partition wall panel 2. The partition wall block 28 and the partition wall slot 29 are used to limit the connection between two adjacent partition wall panels 2.
[0056] like Figure 1-4 As shown, between two adjacent exterior wall panels 1, the exterior wall slot 27 at the bottom of the upper exterior wall panel 1 is aligned with the exterior wall insert 26 at the top of the lower exterior wall panel 1. By pushing the exterior wall panel 1 laterally, the exterior wall insert 26 can be inserted into the exterior wall slot 27, thus limiting the height between the upper and lower exterior wall panels 1. Similarly, when installing the partition wall panel 2, by aligning the partition wall slot 29 with the partition wall insert 28 and pushing the upper partition wall panel 2 laterally, a connection can be formed between the upper and lower partition wall panels 2.
[0057] The working process of this embodiment is as follows: In the construction of prefabricated buildings such as student apartments, on the same floor, the first connecting block 3 of one exterior wall panel 1 is inserted into the connecting groove 5 of another exterior wall panel 1. At the same time, bolts are inserted into the first bolt hole 10 and the second bolt hole 11 and the bolts are tightened with nuts to complete the pre-connection between the two exterior wall panels 1. Afterwards, if the partition wall panel 2 does not need to be installed, the personnel connect the sleeve 15 to the gear 21 and rotate the sleeve 15 until the protrusion 24 fits against the side wall of the cavity 12 and the linkage plate 22 fits against the side wall of the sliding cavity 13 to complete the connection between the two exterior wall panels 1. If the partition wall panel 2 needs to be connected, the cover plate in the second through groove 9 is removed, the second connecting block 4 is inserted between the first through groove 6 and the second through groove 9, and then the sleeve 15 is rotated to lock the locking pin 23 between the first connecting block 3, the connecting groove 5 and the second connecting block 4 to complete the assembly of the partition wall panel 2.
[0058] The upper and lower adjacent exterior wall panels 1 can be quickly connected through exterior wall inserts 26 and exterior wall slots 27, and the upper and lower adjacent partition wall panels 2 can be quickly connected through partition wall inserts 28 and partition wall slots 29.
