Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a prefabricated component connection device, building structure and adjustment device. Background Technology

[0002] Precast component connection devices are mainly used for connecting precast components in prefabricated buildings, such as the assembly connection between precast concrete bodies. Connecting and assembling precast components through precast component connection devices can greatly improve the construction speed.

[0003] In existing precast component connection devices, the male and female connectors mainly employ two connection methods: snap-fit ​​connection and threaded connection. Snap-fit ​​connection devices use a snap-fit ​​connection between the male and female connectors, resulting in a locked, non-return state after assembly, leading to poor connection stability, difficulty in precisely controlling the snap-fit ​​position, and gaps between the connecting surfaces. Threaded connection devices connect the male and female connectors via threads. However, since both the male and female connectors are located within the heavy and bulky precast components, threaded connections are difficult to assemble, making it hard to fully assemble the connectors, and gaps easily form between the connecting surfaces, thus affecting connection stability.

[0004] Therefore, it is essential to design a prefabricated component connection device that is stable and easy to assemble. Utility Model Content

[0050] like Figures 1 to 3As shown, this embodiment proposes a prefabricated component connection device, including a male connector 100 and a female connector 200. The male connector 100 includes a male sleeve 110 and a bolt 120. The male sleeve 110 has a receiving cavity 111 formed within it. The bolt 120 includes a head 121 and a connecting rod 122. The head 121 is located within the receiving cavity 111, and the connecting rod 122 extends out of the receiving cavity 111. The female connector 200 includes a female sleeve 210 and a nut 220. The female sleeve 210 has an installation cavity 211 formed within it, and the nut 220 is located within the installation cavity 211. The male connector 100 and the female connector 200... When the assembly 200 is connected, the connecting rod 122 of the bolt 120 is inserted into the mounting cavity 211 of the female sleeve 210 and threadedly connected to the nut 220; an adjustment part 300 is provided on one of the bolt 120 and the nut 220, the adjustment part 300 is used to adjust the rotational displacement of the nut 220 on the bolt 120, the adjustment part 300 is located in the receiving cavity 111 or the mounting cavity 211, and an insertion hole 310 corresponding to the adjustment part 300 is provided on one of the male sleeve 110 and the female sleeve 210, so that the adjustment device can pass through the insertion hole 310 to adjust the adjustment part 300.

[0051] In this technical solution, a fixed connection is achieved by setting a threaded connection between the bolt 120 in the male sleeve 110 and the nut 220 in the female sleeve 210. An adjustment part 300 is set on one of the bolt 120 and the nut 220 to adjust the rotational displacement of the nut 220 on the bolt 120. An insertion hole 310 corresponding to the adjustment part 300 is set on one of the male sleeve 110 and the female sleeve 210, so that the adjustment device can pass through the insertion hole 310 and rotate the adjustment part 300 to adjust the rotational displacement of the nut 220 on the bolt 120. The engagement position of the nut 220 and the bolt 120 is adjusted to the specified position. When the above-mentioned precast component connecting device is used to connect precast building components, the connecting surfaces of the precast components can be completely fitted to form a stable connection relationship. It is only necessary to insert the adjustment device into the adjustment part 300 for rotational adjustment. The adjustment process is simple and easy to assemble.

[0052] Specifically, such as Figures 1 to 3As shown, one of the bolt 120 and the nut 220 is provided with an adjusting part 300, and the other of the bolt 120 and the nut 220 is provided with an anti-rotation limiting part 320. The anti-rotation limiting part 320 is used to restrict the nut 220 and the bolt 120 from rotating synchronously when the adjusting part 300 is adjusted. By adjusting the adjusting part 300, one of the bolt 120 or the nut 220 can be rotated. By providing the anti-rotation limiting part 320 on the other, the other is prevented from rotating when one rotates. That is, by providing the adjusting part 300 and the anti-rotation limiting part 320, the bolt 120 and the nut 220 can rotate relative to each other when the adjusting part 300 is adjusted, so that the nut 220 is tightened on the bolt 120, thereby forming a stable connection between the male connector 100 and the female connector 200.

[0053] Specifically, the adjusting part is configured as an adjusting tooth 330 or an adjusting hole 340. In some embodiments, such as... Figure 10 , 13 As shown in Figure 16, the adjusting tooth 330 includes protruding teeth and tooth grooves, which are evenly staggered along the circumferential direction of the bolt 120 or nut 220, such as... Figure 10 As shown, the adjusting tooth 330 is disposed on the head 121 of the bolt 120 and is arranged horizontally on the end face of the head 121, as shown. Figure 13 As shown, the adjusting tooth 330 is disposed on the bottom end face of the nut 220 and is arranged horizontally on the bottom end face of the nut 220, as shown. Figure 16 As shown, the adjusting tooth 330 is disposed on the head 121 of the bolt 120 and is vertically disposed on the side of the head 121; in some embodiments, such as Figure 17 As shown, the adjusting holes 340 are evenly distributed along the circumferential direction of the bolt 120 or nut 220. It should be noted that, in this embodiment, the positions of the adjusting teeth 330 and the adjusting holes 340 on the bolt 120 or nut 220 can be adjusted, such as by setting them at other positions on the head 121 of the bolt 120 and the connecting rod 122.

[0054] In some embodiments, such as Figure 1 , 3 As shown in Figures 4 and 10, the head 121 of the bolt 120 is provided with an adjusting tooth 330, and the side wall of the male sleeve 110 is provided with an insertion hole 310 corresponding to the adjusting tooth 330. Figure 14 , 15As shown, the nut 220 is provided with an anti-rotation limiting part 320, which is configured as a limiting protrusion 321 or a limiting groove 322. The inner side wall of the female sleeve 210 is provided with a limiting groove 322 or a limiting protrusion 321 that cooperates with the limiting protrusion 321 or the limiting groove 322 to form an interlocking connection. When the nut 220 and the female sleeve 210 are in an interlocking connection state, the nut 220 and the female sleeve 210 cannot rotate relative to each other. When the adjusting device adjusts the adjusting teeth 330, the bolt 120 rotates relative to the male sleeve 110 and the nut 220, and the nut 220 rotates and moves in the axial direction relative to the bolt 120 to achieve tightening or loosening of the nut 220 relative to the bolt 120.

[0055] In some embodiments, such as Figure 2 , 5 As shown in Figure 13, the nut 220 is provided with adjusting teeth 330, and the side wall of the female sleeve 210 is provided with an insertion hole 310 corresponding to the adjusting teeth 330, as shown in Figure 13. Figures 6 to 9 As shown, the bolt 120 is provided with an anti-rotation limiting part 320, which is configured as a limiting protrusion 321 or a limiting groove 322.

[0056] Specifically, such as Figure 6 , 7 As shown, the bolt 120 is provided with an anti-rotation limiting part 320, and the anti-rotation limiting part 320 is provided with a limiting protrusion 321. The second connecting member 230 is provided with a limiting groove 322 that cooperates with the limiting protrusion 321 of the anti-rotation limiting part 320, so that the bolt 120 and the second connecting member 230 form an interlocking connection, preventing the bolt 120 from rotating relative to the male sleeve 110 and the female sleeve 210. When the adjusting device adjusts the adjusting teeth 330, the nut 220 rotates relative to the bolt 120 (male sleeve 110 and female sleeve 210). By rotating and moving the nut 220 relative to the bolt 120 in the axial direction, the nut 220 can be tightened or loosened relative to the bolt 120.

[0057] In some embodiments, such as Figure 8 , 9 As shown, the bolt 120 is provided with an anti-rotation limiting part 320 that cooperates with the first connecting member 130. The anti-rotation limiting part 320 is provided with a limiting protrusion 321. The first connecting member 130 is provided with a limiting groove 322 that cooperates with the limiting protrusion, so that the bolt 120 and the first connecting member 130 form an interlocking connection, preventing the bolt 120 from rotating relative to the male sleeve 110 and the female sleeve 210. When the adjusting device adjusts the adjusting teeth 330, the nut 220 is tightened or loosened relative to the bolt 120.

[0058] In some embodiments, such as Figure 3 , 12 As shown, the nut 220 is wedge-shaped with an inclined surface on its outer side. The inner side of the second connector 230 is fitted onto the outer side of the nut 220, and a conical cavity is formed in the second connector 230 to mate with the nut 220. When the nut 220 is tightened on the bolt 120, the wedge-shaped inclined surface of the nut 220 fits into the conical cavity of the second connector 230. The friction between the outer side of the nut 220 and the inner side of the second connector 230 prevents rotation between the nut 220 and the second connector 230. The nut 220 is also provided with an anti-rotation limiting part 320, which is a through groove arranged along the axial direction of the nut 220. The through groove gradually narrows during the tightening process of the nut 220, so that the diameter of the nut 220 gradually decreases. When an axial force is applied, the nut 220 and the second connector 230 are gradually pressed together, and the friction gradually increases, preventing rotation.

[0059] In some embodiments, such as Figure 14 , 15 As shown, an anti-rotation limiting part 320 is provided on the outer side of the nut 220, and a limiting protrusion 321 is provided on the anti-rotation limiting part 320. A limiting groove 322 that cooperates with the limiting protrusion 321 is provided in the mounting cavity of the female sleeve 210, so that the nut 220 and the female sleeve 210 form an interlocking connection to prevent the nut 220 from rotating relative to the female sleeve 210.

[0060] It should be noted that in other embodiments, the head of the bolt 120 is provided with an anti-rotation limiting part 320 (not shown in the figure), and the anti-rotation limiting part 320 is provided with a limiting protrusion 321 or a limiting groove 322; the male sleeve 110 is provided with a limiting groove 322 or a limiting protrusion 321 that cooperates with the limiting protrusion 321 or the limiting groove 322 of the head 121 of the bolt 120. Its anti-rotation limiting method is the same as or similar to that of the above embodiments, and will not be described again here. In addition, the specific structure of the anti-rotation limiting part 320 in the figure of this embodiment is not intended to limit this embodiment. All limiting structures that can achieve relative anti-rotation are included in the technical solution of the embodiment, and will not be listed one by one in this embodiment.

[0061] In some embodiments, such as Figure 1 , 2As shown in Figure 11, the male connector assembly 100 further includes a first connector 130. The first connector 130 and the male sleeve 110 are provided with a detachable fixed connection, and the first connector 130 is sleeved with the bolt 120 to restrict the head 121 of the bolt 120 within the receiving cavity 111. In this embodiment, the first connector 130 and the male sleeve 110 are provided with a threaded connection. In other embodiments, the first connector 130 and the male sleeve 110 may also be provided with a non-rotatable snap-fit ​​connection.

[0062] In some embodiments, such as Figure 1 , 2 As shown in Figure 7, the female connector assembly 200 further includes a second connector 230, which is detachably and fixedly connected to the opening of the mounting cavity 211 of the female connector sleeve 210 to confine the nut 220 within the mounting cavity 211. In this embodiment, the second connector 230 and the female connector sleeve 210 are threaded together. In other embodiments, the second connector 230 and the female connector sleeve 210 may also be connected by a snap-fit ​​connection that prevents relative rotation.

[0063] In some embodiments, at least one of the receiving cavity 111 of the male sleeve 110 and the mounting cavity 211 of the female sleeve 210 is provided with an elastic element 400, the elastic element 400 being used to apply opposing axial thrusts to the bolt 120 and / or the nut 220, respectively. In this embodiment, as... Figure 1-3 As shown, the elastic element 400 is configured as a compression spring, which applies a relative axial thrust to the bolt 120 and the nut 220 respectively. By setting the elastic element 400 to clamp the bolt 120 and the nut 220 at both ends in the male sleeve 110 and the female sleeve 210, it is convenient for the adjusting teeth 330 on the bolt 120 or the nut 220 to align with the insertion hole 310, and it is also convenient for the bolt 120 and the nut 220 to be tightened together.

[0064] In this embodiment, the insertion hole 310 is a round hole, an elliptical hole, or a U-shaped hole. When the insertion hole 310 is an elliptical hole or a U-shaped hole, the elliptical hole or U-shaped hole is set along the axial direction of the male sleeve 110 or the female sleeve 210, so as to facilitate the adjustment device to be inserted into the insertion hole 310 and mesh with the adjustment tooth 330 for alignment.

[0065] In this embodiment, there are several insertion holes 310, that is, there may be one or more insertion holes 310. In the figure, two insertion holes 310 are arranged symmetrically.

[0066] like Figure 18 , 19As shown, this embodiment also proposes a building structure, including a first prefabricated component 500 and a second prefabricated component 600. The first prefabricated component 500 and the second prefabricated component 600 are assembled and connected by the prefabricated component connecting device described in any of the above embodiments. The first prefabricated component 500 is provided with the male connector 100, and the second prefabricated component 600 is provided with the female connector 200. One of the first prefabricated component 500 and the second prefabricated component 600 is provided with an adjustment through hole 700 corresponding to and communicating with the insertion hole 310.

[0067] In some embodiments, such as Figure 18 As shown, a male connector 100 is provided inside the first prefabricated component 500. An adjusting tooth 330 is provided on the bolt 120. An insertion hole 310 corresponding to the adjusting tooth 330 is provided on the male connector sleeve 110. An adjusting through hole 700 corresponding to the adjusting tooth 330 and the insertion hole 310 is provided on the first prefabricated component 500. During installation, the driving tooth of the adjusting device is inserted into the adjusting through hole 700 and engages with the adjusting tooth 330. By rotating the adjusting device, the bolt 120 and the nut 220 are tightened relative to each other, thereby making the connecting surfaces of the first prefabricated component 500 and the second prefabricated component 600 fit together and forming a stable fixed connection between the first prefabricated component 500 and the second prefabricated component 600.

[0068] In some embodiments, such as Figure 19 As shown, the second prefabricated component 600 is provided with a female connector assembly 200. The nut 220 is provided with an adjusting tooth 330, and the female connector sleeve 210 is provided with an insertion hole 310 corresponding to the adjusting tooth 330. The second prefabricated component 600 is provided with an adjusting through hole 700 corresponding to the adjusting tooth 330 and the insertion hole 310. During installation, the driving tooth of the adjusting device is inserted into the adjusting through hole 700 and engages with the adjusting tooth 330. By rotating the adjusting device, the bolt 120 and the nut 220 are tightened relative to each other, thereby making the connecting surfaces of the first prefabricated component 500 and the second prefabricated component 600 fit together and forming a stable fixed connection between the first prefabricated component 500 and the second prefabricated component 600. The installation and adjustment process is simple. After installation, an elastic plug, such as a rubber plug or a wooden plug, can be used to seal the insertion hole 310. Then, an injection needle is inserted into the elastic plug to inject a hardenable liquid sealing material such as water glass or cement slurry into the elastic plug. After the hardenable liquid sealing material hardens, the connection device is sealed, protected from corrosion, and the threads are prevented from loosening.

[0069] like Figure 20-23As shown, this embodiment also proposes an adjustment device for adjusting the prefabricated component connection device as described in any of the above embodiments. The device includes a handle 810 and an adjustment rod 820 fixedly connected. The end of the adjustment rod 820 is provided with a driving part, which can pass through the insertion hole 310 to drive the adjustment part 300, causing the bolt 120 and nut 220 to rotate relative to each other. In some embodiments, such as... Figure 20 As shown, the end of the adjusting rod 820 is provided with a driving tooth 830, which meshes with the adjusting tooth 330. In other embodiments, the end of the adjusting rod 820 can be inserted into the adjusting hole 340 or abut against the adjusting tooth 330, and can push the adjusting hole 340 or the adjusting tooth 330 to make the bolt 120 or nut 220 rotate relative to each other.

[0070] In some embodiments, such as Figure 21 , 23 As shown, the nut 220 is provided with an adjusting tooth 330. The driving tooth 830 of the adjusting device meshes with the adjusting tooth 330 on the nut 220. By rotating the adjusting device, the nut 220 is rotated and moved on the bolt 120, thereby tightening or loosening the nut 220 and the bolt 120 relative to each other.

[0071] In some embodiments, such as Figure 22 As shown, the bolt 120 is provided with an adjusting tooth 330. The driving tooth 830 of the adjusting device meshes with the adjusting tooth 330 on the top of the bolt 120. By rotating the adjusting device, the nut 220 is rotated and moved on the bolt 120, thereby tightening or loosening the nut 220 and the bolt 120 relative to each other.

[0072] In summary, this embodiment achieves a fixed connection by setting a threaded connection between the bolt 120 in the male sleeve 110 and the nut 220 in the female sleeve 210. An adjusting tooth 330 is provided on one of the bolt 120 and the nut 220 to adjust the rotational displacement of the nut 220 on the bolt 120. An insertion hole 310 corresponding to the adjusting tooth 330 is provided on one of the male sleeve 110 and the female sleeve 210, allowing the adjusting device to pass through the insertion hole 310 and rotate the adjusting tooth 330, thereby adjusting the rotational displacement of the nut 220 on the bolt 120 and adjusting the engagement position of the nut 220 and the bolt 120 to the specified position. When the above-mentioned precast component connecting device is used for the fixed connection of precast building components, the connecting surfaces of the precast components can be completely fitted together, forming a stable connection relationship. Only the adjusting device needs to be inserted into the adjusting tooth 330 for rotational adjustment; the adjustment process is simple and easy to assemble.
