[0001] This invention relates to the field of prefabricated building installation, and in particular to a prefabricated wall panel splicing structure and method thereof. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] Prefabricated buildings include prefabricated wall panels. Prefabricated wall panels need to be spliced ​​during use. Traditional splicing methods for wall panels are complicated and require tools such as screws, nuts, and pneumatic nail guns. The splicing process is cumbersome and inconvenient for people to operate, resulting in a lot of time and effort being spent on the installation of prefabricated wall panels. Therefore, a splicing structure and method for prefabricated wall panels is proposed to solve the above problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a prefabricated wall panel splicing structure, including a first wall panel and a second wall panel. The first wall panel and the second wall panel are provided with a plurality of slots and blocks at equal intervals on opposite sides. The slots and blocks are adapted to each other. The first wall panel is also provided with an insertion hole and a locking chamber that communicate with the slots. The blocks are provided with through holes. Locking fasteners that pass through the through holes and extend into the locking chamber are inserted into the insertion holes. The locking fasteners are used to lock the connection between the first wall panel and the second wall panel.

[0006] In a preferred embodiment, the locking device includes an outer sleeve, a retractable middle sleeve extending through the outer sleeve, a retractable inner sleeve inserted into the middle sleeve, and a push-in self-retracting component disposed at the bottom end of the inner sleeve.

[0007] In a preferred embodiment, the self-retracting jacking component includes a thin rod, a thick rod, and a base arranged sequentially at the bottom of the inner tube. The outer diameter of the thin rod is smaller than the diameter of the thick rod and the inner tube. A telescopic ring and a first telescopic spring are movably fitted on the outside of the thin rod. The first telescopic spring is located between the telescopic ring and the inner tube. Several locking claws are hinged on the base. A connecting rod is hinged to the top of the locking claws. The other end of the connecting rod is hinged to the telescopic ring.

[0008] The locking chamber has a convex cross-section.

[0009] In a preferred embodiment, a tension spring is provided between the inner top wall of the middle sleeve and the top end of the inner tube, an elastic limiting component is provided at the top end of the inner tube, and a limiting hole is provided on the wall of the middle sleeve for the elastic limiting component to pass through. The limiting hole is located in the lower middle part of the middle sleeve and is used to temporarily limit the length of the inner tube extending out.

[0010] In a preferred embodiment, an abutment ring is provided on the inner wall surface of the outer sleeve, which is used to retract the elastic limiting component after contacting it.

[0011] In a preferred embodiment, the elastic limiting component includes a telescopic cavity that extends laterally through the inner tube, a limiting groove disposed on the inner wall surface of the telescopic cavity, a second telescopic spring built into the telescopic cavity, telescopic members disposed at both ends of the second telescopic spring and extending to the outside of the telescopic cavity, and a limiting block disposed at the end of the telescopic member and slidably connected to the limiting groove, wherein the front end of the telescopic member passes through a limiting hole.

[0012] In a preferred embodiment, the top of the abutment ring is a sloped surface that slopes downward from the outer edge to the inner edge, the top of the limiting hole is a sloped surface that slopes upward from the outside to the inside, and the upper and lower sides of the front end of the telescopic member are respectively provided with sloped surfaces corresponding to the limiting hole and the abutment ring.

[0013] In a preferred embodiment, the inner wall of the outer sleeve is provided with a telescopic limiting groove, which is located below the abutment ring, and the outer side of the middle sleeve is provided with a limiting ring that is slidably connected to the telescopic limiting groove.

[0014] In a preferred embodiment, an internal threaded sleeve is pre-installed in the insertion hole, and the outer sleeve is provided with a threaded thread that matches the internal threaded sleeve. A telescopic handle is provided at the top of the inner tube.

[0017] S2. Install the outer sleeve of the locking fastener into the insertion hole. The self-retracting component is kept in a contracted state under the constraint of the hole. Then push the middle sleeve to pass through the through hole and let the self-retracting component enter the locking chamber, so that the self-retracting component is unconstrained and opens.

[0018] S3. Continue pushing the middle sleeve until the elastic limiting component on the inner tube contacts the abutment ring. The elastic limiting component retracts under the contact with the abutment ring, releasing the limitation on the inner tube.

Detailed Implementation

[0031] Example 1

[0032] like Figure 1-8 As shown, a prefabricated wall panel splicing structure and method thereof are disclosed. The prefabricated wall panel splicing structure includes a first wall panel 1 and a second wall panel 2. A plurality of slots 100 and blocks 200 are equidistantly arranged on opposite sides of the first wall panel 1 and the second wall panel 2. The slots 100 and blocks 200 are adapted to each other. In this embodiment, the number of slots 100 and blocks 200 are five respectively. It should be noted that the structure of the first wall panel 1 and the second wall panel 2 is the same. The slots 100 are opened on the left side of the wall panel, and the blocks 200 are integrally formed on the right side.

[0033] The first wall panel 1 is also provided with an insertion hole 101 and a locking chamber 102 that are connected to the slot 100. The card block 200 is provided with a through hole 201. When the card block 200 is inserted into the slot 100, the insertion hole 101, the through hole 201 and the locking chamber 102 are aligned and connected to form a line. A locking fastener 3 is inserted into the insertion hole 101, which passes through the through hole 201 and extends into the locking chamber 102. The locking fastener 3 is used to lock the connection between the first wall panel 1 and the second wall panel 2.

[0034] In a preferred embodiment, the locking device 3 includes an outer sleeve 31, a retractable middle sleeve 32 extending through the outer sleeve 31, a retractable inner sleeve 33 inserted into the middle sleeve 32, and a push-in self-retracting component 34 disposed at the bottom end of the inner sleeve 33.

[0035] Among them, the outer sleeve 31 is a hollow cylinder with openings at the top and bottom, the middle sleeve 32 is a hollow cylinder with openings at the bottom and its outer diameter is smaller than the inner diameter of the outer sleeve 31, and the inner tube 33 is a cylinder with an outer diameter smaller than the outer diameter of the middle sleeve 32.

[0036] In a preferred embodiment, the self-retracting jacking component 34 includes a thin rod 340, a thick rod 341, and a base 342 sequentially arranged at the bottom of the inner tube 33. The inner tube 33, the thin rod 340, the thick rod 341, and the base 342 are integrally formed. The outer diameter of the thin rod 340 is smaller than the diameter of the thick rod 341 and the inner tube 33. A telescopic ring 343 and a first telescopic spring 344 are movably fitted on the outside of the thin rod 340. The first telescopic spring 344 is located between the telescopic ring 343 and the inner tube 33. Several locking claws 345 are hinged on the base 342. A connecting rod 346 is hinged to the top of the locking claws 345. The other end of the connecting rod 346 is hinged to the telescopic ring 343. In this embodiment, there are three locking claws 345.

[0037] The locking chamber 102 has a convex cross-section.

[0038] When in use, as the self-retracting push-in component 34 pushes forward, the locking claw 345 is constrained by the hole. Through the connecting rod 346, it pushes the telescopic ring 343 upward to compress the first telescopic spring 344, thereby retracting through the hole until it enters the U-shaped locking chamber 102 and fully opens, thus achieving the locking effect. During this process, only the self-retracting push-in component 34 mechanism needs to be pushed forward; no other operation is required to achieve the locking effect.

[0039] In a preferred embodiment, a tension spring 320 is provided between the inner top wall of the middle sleeve 32 and the top end of the inner tube 33. The two ends of the tension spring 320 are fixedly connected to the inner top wall of the middle sleeve 32 and the top end of the inner tube 33, respectively. An elastic limiting component 330 is provided at the top end of the inner tube 33. A limiting hole 321 is provided on the wall surface of the middle sleeve 32 for the elastic limiting component 330 to pass through. The limiting hole 321 is located in the lower middle part of the middle sleeve 32 and is used to temporarily limit the length of the inner tube 33 extending out, so that the tension spring 320 remains taut.

[0040] In a preferred embodiment, an abutment ring 310 is fixedly provided on the inner wall surface of the outer sleeve 31. This ring is used to retract the inner sleeve 33 after contacting the elastic limiting component 330. When the elastic limiting component 330 contacts the abutment ring 310, it restricts the inner sleeve 33, causing the inner sleeve 33 to retract under the rebound of the tension spring 320. This, in turn, pulls back the self-retracting component 34 in the locking chamber 102. The locking effect is achieved by the cooperation between the locking chamber 102 and the self-retracting component 34.

[0041] In a preferred embodiment, the elastic limiting component 330 includes a telescopic cavity 3301 that extends laterally through the inner tube 33, a limiting groove 3302 disposed on the inner wall surface of the telescopic cavity 3301, a second telescopic spring 3303 built into the telescopic cavity 3301, a telescopic member 3304 disposed at both ends of the second telescopic spring 3303 and extending to the outside of the telescopic cavity 3301, and a limiting block 3305 fixed at the end of the telescopic member 3304 and slidably connected to the limiting groove 3302, wherein the front end of the telescopic member 3304 passes through the limiting hole 321.

[0042] In use, the two telescopic components 3304 remain in a protruding state under the tension of the second telescopic spring 3303, thereby passing through the limiting hole 321 to restrict the position of the inner tube 33. The limiting groove 3302 and the limiting block 3305 play a limiting role. At the same time, the telescopic components 3304 will retract after being resisted, thereby releasing the locking of the inner tube 33.

[0043] In the preferred embodiment, the top of the abutment ring 310 is a sloped surface that slopes downward from the outer edge to the inner edge, and the top of the limiting hole 321 is a sloped surface that slopes upward from the outside to the inside. The upper and lower sides of the front end of the telescopic member 3304 are respectively provided with sloped surfaces corresponding to the limiting hole 321 and the abutment ring 310. The design of the sloped surface can make the telescopic member 3304 more flexible and improve the process of use.

[0044] In a preferred embodiment, a telescopic limiting groove 311 is provided on the inner wall surface of the outer sleeve 31. The telescopic limiting groove 311 is located below the abutment ring 310. A limiting ring 322 is fixedly connected to the outside of the middle sleeve 32 and is slidably connected to the telescopic limiting groove 311. The sliding connection between the telescopic limiting groove 311 and the limiting ring 322 facilitates the restriction of the range of motion of the middle sleeve 32.

[0045] In the preferred embodiment, an internal threaded sleeve is pre-set in the insertion hole 101. The internal threaded sleeve is pre-set during the prefabricated wall panel forming process. The outer sleeve 31 is provided with a threaded thread that matches the internal threaded sleeve. The outer sleeve 31 is connected to the internal threaded sleeve by thread, which makes it easier to fix the outer sleeve 31 in the insertion hole 101 by thread, and makes it easier to extend and retract the middle sleeve 32.

[0046] The top of the inner tube 33 is fixed with a telescopic handle 323, which makes it easy for construction personnel to push it.

[0047] In the preferred embodiment, the insertion hole 101 and the locking chamber 102 are staggered from top to bottom, allowing the locking fastener 3 to be inserted alternately between the first wall plate 1 and the second wall plate 2.

[0048] Example 2

[0049] Further explanation in conjunction with Example 1, such as Figure 1-8 The structure shown illustrates a method for assembling prefabricated wall panels, the method comprising:

[0050] S1. Align the locking block 200 of the second wall panel 2 with the corresponding locking slot 100 of the first wall panel 1, and move the second wall panel 2 to insert the locking block 200 into the locking slot 100, and align the insertion hole 101, the through hole 201 and the locking chamber 102.

[0051] S2. Thread the outer sleeve 31 of the locking fastener 3 into the insertion hole 101. The self-retracting push-in component 34 remains in a contracted state under the constraint of the hole. Then push the middle sleeve 32 to pass through the through hole 201 and make the self-retracting push-in component 34 enter the locking chamber 102, so that the self-retracting push-in component 34 is unconstrained and opens.

[0052] S3. Continue pushing the middle sleeve 32 until the elastic limiting component 330 on the inner tube 33 contacts the abutment ring 310. The elastic limiting component 330 retracts under the contact with the abutment ring 310, releasing the limitation on the inner tube 33. The inner tube 33 retracts under the tension of the tension spring 320, thereby keeping the self-retracting push-in component 34 locked in the locking chamber 102.

[0053] S4. Repeat steps S2-S3 to complete the installation of the locking fasteners 3 in all card blocks 200 and card slots 100.
