Prefabricated building and assembly components

Abstract

The present invention relates to the field of building technology, and in particular to a prefabricated building and assembly component, comprising an assembly seat and a locking component arranged on the assembly seat, wherein the locking component comprises a pin fixed in a receiving groove and a lock plate connected to the pin, a lock column connected to the assembly seat, and a pull member connected between the lock column and the lock plate, wherein the spring is sleeved on the pull member, and the lock plate rotates around the pin to the outside of the assembly seat. By a simple operation of rotating the lock column, the pull member can be used to control the synchronous movement of multiple lock plates, especially the lock plates at the four corners at the same time. After releasing the lock column, the spring instantly drives all the lock plates to automatically and synchronously spring into the wall panel positioning groove, realizing a quick locking with a "click and lock" function, which greatly simplifies the operation steps and significantly improves the assembly efficiency of multiple wall panels, especially those connected at the four corners.

Description

Technical Field

[0001] The present invention relates to the field of building technology, and in particular to an assembled building and an assembly component. Background Art

[0002] In the field of industrialized construction, particularly in modular buildings, prefabricated wall panels, partition systems, and wall structures requiring rapid assembly, the rapid and secure connection of wall panels (or wall panel assemblies) is crucial for improving construction efficiency and ensuring structural strength. These applications typically involve multiple wall panels being prefabricated in a factory and then transported to the site, where they must be efficiently and precisely positioned and locked at the four corners or other specific locations to form a complete wall structure. Therefore, developing an assembly component that is easy to operate, reliably locks, and significantly improves assembly efficiency is of great practical significance.

[0003] However, existing assembly components used to connect wall panel corners or edges are generally cumbersome and inefficient. For example, conventional bolt fastening methods require tightening each bolt individually, which is labor-intensive and time-consuming. While snap-on fasteners are slightly faster, they often suffer from insufficient locking force and poor anti-loosening performance. This is particularly true when multiple wall panel locations need to be addressed simultaneously, as the lack of a mechanism that can achieve synchronized, rapid action and secure anti-loosening after locking results in low assembly efficiency. Summary of the Invention

[0006] As a further preference, the locking plate is triangular, one corner of which is connected to the pin shaft, and the other two corners are free ends that can rotate back and forth around the pin shaft between the receiving groove and the periphery of the assembly seat.

[0007] As a further preferred embodiment, a transition pin is installed on the inner side of each of the receiving grooves in the hollow cavity of the assembly seat, and the pull piece is a steel wire. A pull piece passes through each of the transition pins, and one end of each pull piece penetrates into the corresponding receiving groove and passes through the corresponding spring to be connected to the free end of the corresponding lock plate, and the other end of each pull piece is commonly connected to the lock column.

[0008] As a further preferred embodiment, a circular plate is mounted on the lock cylinder, and a circular array of hanging holes for connecting the pull piece is provided on the circular plate.

[0009] As a further preferred embodiment, a buckle cavity is provided inward from the outer end of the lock column, and an internal thread is provided in the buckle cavity. The fastener assembly includes a stud that is buckled into the buckle cavity and connected to the internal thread. The fastener assembly also includes an annular retaining spring arranged on the lock column, and the inner end of the stud is provided with a chamfered surface. A movable groove for placing the annular retaining spring is provided in the radial direction of the lock column. One end of the annular retaining spring extends into the buckle cavity from the movable groove and is provided with a pressure-bearing portion bent in the direction of the chamfered surface. The other end of the annular retaining spring extends from the movable groove to the outside of the buckle cavity and is provided with a clamping portion.

[0012] The beneficial effects of the present invention compared to the prior art are:

[0013] Efficient and Fast Assembly: A simple rotation of the locking post allows the locking plates to be controlled synchronously through the pull mechanism, particularly at all four corners. Upon releasing the locking post, a spring instantly drives all locking plates into the wall panel's positioning slots, automatically and synchronously snapping them into place. This allows for quick, one-click locking, greatly simplifying the process and significantly improving the efficiency of assembling multiple wall panels, especially at the four corners. The spring's elastic force acts as the driving force, ensuring the locking plates snap quickly, forcefully, and precisely into the wall panel's positioning slots, forming a secure initial connection. This effectively prevents problems with loose connections caused by uneven manual force. A fastener assembly is introduced, which provides a secondary locking mechanism after the spring-driven locking plates complete the initial engagement. This fundamentally prevents accidental rotation of the locking post due to vibration or external forces, thereby completely locking the pull mechanism and locking plates in place and ensuring they remain securely engaged in the wall panel's positioning slots. This effectively addresses the persistent loosening issue of traditional snap-fit ​​structures and significantly improves the long-term stability and resistance to loosening of the joint.

DETAILED DESCRIPTION

[0023] The above and other embodiments and advantages of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0024] In one embodiment, Figures 1-8 As shown:

[0025] The present embodiment provides an assembly component, including an assembly seat 10 and a locking component 20 arranged on the assembly seat 10, a receiving groove 110 is opened on the periphery of the assembly seat 10, the locking component 20 includes a pin 210 fixed in the receiving groove 110 and a lock plate 220 connected to the pin 210, a lock column 230 connected to the assembly seat 10, and a pull member 240 connected between the lock column 230 and the lock plate 220, a spring 111 is provided in the receiving groove 110, and the spring 111 is sleeved on the pull member 240, and the spring The two ends of 111 are elastically supported between the receiving groove 110 and the lock plate 220, and the support of the spring 111 causes the lock plate 220 to rotate around the pin shaft 210 to the outside of the assembly seat 10. The rotating lock column 230 drags the pull member 240 to rotate the lock plate 220 from the outside of the assembly seat 10 to the inside of the receiving groove 110. The locking assembly 20 also includes a fastener assembly 250 that is quickly buckled on the lock column 230 to quickly lock the lock column 230 to a wall structure (for example, a building wall, plate, surface, etc. composed of multiple wall panels).

[0026] The core of the working principle of the present invention is: by operating the lock column 230 to drive a set of precise linkage mechanisms, the lock plate 220 is automatically popped out and locked reliably. The specific process is as follows: in the initial state or unlocked state, the spring 111 sleeved on the pull member 240 is in a compressed or energy-storage state, and its two ends are elastically supported between the inner wall of the receiving groove 110 and the lock plate 220. Under the elastic support of the spring 111, the lock plate 220 rotates outward around the pin 210 so that it protrudes outside the periphery of the assembly seat 10. When it is necessary to lock the assembly seat 10 in the preset positioning groove on the wall panel wall structure, the receiving groove 110 of the assembly seat 10 is aligned with the wall panel positioning groove position. At this time, the operator rotates the lock column 230. The rotation of the lock column 230 transmits the pulling force through the pull member 240 connected thereto. This pulling force overcomes the elastic force of spring 111, pulling the connected lock plate 220, forcing the lock plate 220 to rotate inward about the pin 210, causing it to retract from its protruding position outside the assembly base 10 and retract into the receiving slot 110, making room for insertion into the wallboard positioning slot. Once the assembly base 10 is in place, the rotating lock column 230 is released. At this point, the stored elastic force of spring 111 is released, and its two ends push against the receiving slot 110 and the lock plate 220, driving the lock plate 220 to quickly and forcefully rotate outward about the pin 210 to reset, causing it to instantly snap into and engage the corresponding positioning slot in the wallboard, completing a quick and reliable initial locking. Finally, the fastener assembly 250 is quickly fastened to the lock post 230, securing the lock post 230 to the wall panel structure or mounting base. This prevents the entire assembly from falling off. It also effectively locks the circumferential rotation of the lock post 230, preventing it from rotating due to vibration or external forces. This ensures that the lock plate 220, which is ejected by the spring 111 and engaged in the wall panel positioning slot, remains locked, completely eliminating the risk of the lock plate 220 becoming loose and significantly improving the overall stability and long-term reliability of the connection. The entire linkage process is efficient and synchronized, significantly improving the efficiency of wall panel assembly.

[0027] The assembly base 10 is rectangular and hollow inside, with four receiving slots 110 located at the four corners of the assembly base 10. Each receiving slot 110 is fitted with a pin 210, and each pin 210 is fitted with a locking plate 220. The locking plate 220 is triangular in shape, with one corner connected to the pin 210 and the other two corners free, allowing it to rotate back and forth around the pin 210 between the receiving slot 110 and the periphery of the assembly base 10.

[0028] In the initial state, the springs 111 within the four receiving slots 110 are compressed and stored. Under the elastic force of each spring 111, the four lock plates 220 rotate outward about their respective pins 210, protruding beyond the outline of the assembly base 10 and entering a pre-locked state. The assembly base 10 is then placed in a preset position on the wallboard, with the receiving slots 110 at its four corners aligned with the four corresponding positioning slots on the wallboard. The operator rotates the lock post 230. This drives the pull member 240. The pull member 240, through its structure, simultaneously and synchronously pulls the four lock plates 220. Under the tensile force, the four lock plates 220 overcome the elastic force of their corresponding springs 111 and rotate inward about their respective pins 210. This causes the four lock plates 220 to simultaneously retract from their protruding state and fully retract into their respective receiving slots 110, clearing the way for the assembly base 10 to fully settle into its wallboard positioning slot. When the lock column 230 is released, the springs 111 in the four receiving slots 110 simultaneously release the stored elastic force, and under the push of the elastic force, the four lock plates 220 each quickly rotate outward around their pins 210 to reset. This action causes the four lock plates 220 to instantly and synchronously spring into the positioning slots corresponding to the four corners of the wall panel, achieving the purpose of the four wall panels being synchronously engaged and locked by the four lock plates 220 through the positioning slots at the four corners. This achieves the purpose of quickly assembling four wall panels together with a set of locking components 20, improving the assembly efficiency of the wall. Finally, the fastener assembly 250 is fastened to the lock column 230 and fixed. This operation locks the rotational position of the lock column 230, preventing it from rotating, thereby ensuring that the pull member 240 maintains its restraint state on the four lock plates 220 and does not change. The long-term stability and reliability of the synchronous locking of the four corners are guaranteed.

[0029] It needs to be further explained that, Figure 2 、 Figure 3 、 Figure 4 As shown, an over-pin 120 is installed on the inner side of each receiving groove 110 in the hollow cavity of the assembly seat 10, and the pull member 240 is a steel wire. A pull member 240 passes through each over-pin 120, and one end of each pull member 240 passes through the corresponding receiving groove 110, and passes through the corresponding spring 111 to be connected to the free end of the corresponding lock plate 220, and the other end of each pull member 240 is commonly connected to the lock column 230. The transition pin 120 has a directional effect on the pulling members 240. The four pulling members 240 have the same length and are driven by the same lock column 230 to rotate. Under the directional effect of the transition pin 120, the force and torque applied to the four locking plates 220 are consistent. The four locking plates 220 are simultaneously rotated into the four receiving slots 110. When the lock column 230 is rotated in the opposite direction, the four pulling members 240 rotate in the opposite direction at the same time, ensuring that the four locking plates 220 are simultaneously locked into the positioning slots of the four wall panels, further improving the splicing efficiency of the wall panels.

[0030] It needs to be further explained that, Figure 2 、 Figure 3 As shown, a circular plate 2301 is mounted on the lock cylinder 230. The circular plate 2301 has a circular array of hanging holes 2302 for connecting to the pull member 240. When the lock cylinder 230 rotates, the circular plate 2301 rotates, which in turn rotates the hanging holes 2302. The hanging holes 2302 then pull the pull member 240, which in turn pulls the lock plate 220 to rotate.

[0031] It needs to be further explained that, Figure 1 、 Figures 5 to 8 As shown, the specific method of the fastener assembly 250 is described as follows: first, a buckle cavity 2303 is opened inward from the outer end of the lock column 230, and an internal thread is opened in the buckle cavity 2303; secondly, the fastener assembly 250 includes a stud 2501 that is buckled into the buckle cavity 2303 and connected to the internal thread; the fastener assembly 250 also includes an annular retaining spring 2502 arranged on the lock column 230, and a chamfered surface 2503 is opened at the inner end of the stud 2501; a movable groove 2304 for placing the annular retaining spring 2502 is opened in the radial direction of the lock column 230; one end of the annular retaining spring 2502 extends into the buckle cavity 2303 from the movable groove 2304, and is provided with a pressure portion 25021 facing and bending in the direction of the chamfered surface 2503; the other end of the annular retaining spring 2502 extends from the movable groove 2304 to the outside of the buckle cavity 2303, and is provided with a clamping portion 25022. The screw 2501 is rotated so that the chamfered surface 2503 at its inner end presses against the pressure-bearing portion 25021 of the annular retaining spring 2502 extending into the buckle cavity 2303. The pressure-bearing portion 25021 is forced to push the annular retaining spring 2502 to move radially along the movable groove 2304, so that the clamping portion 25022 at the outer end of the annular retaining spring 2502 is clamped into the wall panel. The radial movement of the annular retaining spring 2502 is controlled by threaded fastening, forcing the lock column 230 to be radially fixed to the wall panel. In addition to radially fixing the entire assembly component to the wall panel, it also prevents the assembly component from rotating.

[0032] The present invention also discloses an assembled building, which includes at least multiple wall panels 30 assembled together by assembly components. The wall panels 30 are rectangular, and the inner sides of the four corners are provided with positioning grooves 310 that match and connect with the assembly seat 10. The positioning grooves 310 are provided with lock grooves 320 that form a snap-fit ​​relationship with the lock plate 220 after being rotated outward. An arc opening 330 is opened from the positioning grooves 310 to the outside of the wall panel 30, which forms an insertion relationship with the lock column 230. The arc opening 330 is provided with a snap-fitting groove 340 that forms a snap-fitting relationship with the snap-fitting portion 25022 of the annular retaining spring 2502.

[0033] When in use, the four wall panels 30 are spliced ​​together at one time. The diagonal positions of the four wall panels 30 form a square groove for placing the assembly seat 10 through the positioning groove 310. At the same time, the diagonal positions of the four wall panels 30 form a circular through hole through the arc opening 330. First, the lock column 230 is rotated, and the lock column 230 drags the four pull members 240, and the pull members 240 drag the four lock plates 220 to rotate quickly into the receiving grooves 110 where they are located, until the assembly seat 10 is stuck in the diagonal square grooves of the four wall panels 30. At the same time, the four lock plates are also 220 is inserted into the four positioning grooves 310 of the four wall panels 30. At the same time, the lock column 230 carries the stud 2501 through the through hole formed by the four arc openings 330 of the wall panel 30 to reach the other side of the wall panel 30, and brings the annular retaining spring 2502 to the position of the retaining groove 340. The spring 111 is compressed and shortened under the extrusion of the lock plate 220 rotating back into the receiving groove 110. The four springs 111 rebound and lengthen and simultaneously provide thrust to the four lock plates 220, forcing the four lock plates 220 to press Figure 2 、 Figure 3 , quickly snap into the locking slots 320 of the four positioning slots 310, so that the four wall panels 30 are quickly assembled together, and the screw 2501 is rotated so that the chamfered surface 2503 of its inner end presses against the pressure-receiving portion 25021 of the annular retaining spring 2502 extending into the buckle cavity 2303. The pressure-receiving portion 25021 is forced to push the annular retaining spring 2502 to move radially along the movable slot 2304, so that the clamping portion 25022 at the outer end of the annular retaining spring 2502 is clamped into the clamping slot 340 of the wall panel. By adopting the threaded fastening method, after controlling the radial movement of the annular retaining spring 2502, the locking column 230 is forced to be radially fixed to the wall panel where it is located. In addition to radially fixing the entire assembly component to the wall panel, it also prevents the assembly component from rotating. It should be further explained that according to Figure 5 As shown, the locking plate 220 is tilted when it is rotated out of the receiving groove 110, and the locking groove 320 provided on the wall panel 30 is also tilted. Therefore, when the locking plate 220 is rotated outward and snapped into the corresponding locking groove 320, especially the locking groove 320 between the two wall panels 30, a clamping force is formed under the clamping of the two locking plates 220 and the locking is fixed. In practice, in order to increase the clamping force and ensure that the two wall panels 30 are further locked after being spliced ​​together, a hook portion or other fixing structure can be further provided on the outside of the locking plate 220 (not shown in the figure, only the locking plate is shown). 220 and locking groove 320), a recessed groove corresponding to the hook portion or other fixing structure is further provided in the locking groove 320. For example, when the locking plate 220 is inserted into the locking groove 320, the hook portion or other fixing structure is used to engage with the recessed groove in the locking groove 320 to improve the locking effect. Through this splicing method, more wall panels 30 and more assembly components are sequentially spliced ​​together to form a building wall. The wall panels 30 transmit pressure to each other, or the building wall spliced ​​in this way is stacked together to increase the thickness and enhance the fixing force.
