Description

Technical Field

[0001] This utility model relates to the field of quick connection of prefabricated building components, and more specifically, to a quick-install column-beam connection buckle. Background Technology

[0002] In traditional building structures, column-beam connections typically require welding, bolts, or other fixing methods. These traditional connection methods are time-consuming to construct and demand a high level of worker skill. As the construction industry places increasing demands on construction efficiency, cost control, and safety, the market demand for column-beam connection technologies that enable quick, safe, and easy connections is constantly growing.

[0003] A search revealed that Chinese Patent Publication No. CN209654373U discloses a "concealed column-beam hanging clip connection device," comprising a mortise and tenon groove on the side wall of a column and a baffle plate connected to the end of a beam. The outer wall of the baffle plate has a tenon that mates with the mortise and tenon is formed by an opening in the baffle plate. When the tenon is inserted into the mortise and tenon groove, the baffle plate fits snugly against the side wall of the column. The opening in the baffle plate for the tenon is located within the outer boundary of the beam. In this invention, the opening in the baffle plate for the tenon is located within the outer boundary of the beam, allowing the opening in the baffle plate to be hidden inside the beam after the column and beam are assembled. This avoids debris getting entangled in the opening in the baffle plate, improving the usability of products assembled using this column-beam hanging clip connection device. Furthermore, this concealed column-beam hanging clip connection device is more aesthetically pleasing. However, it still has the following drawbacks:

[0004] (1) When using column-beam connection, the above application makes it difficult to pre-fix the beam when installing the column and the beam, which requires workers to lift the beam for a long time to install it, making it difficult to make the column-beam connection faster and more reliable.

[0005] (2) When using column-beam connection, it is difficult to support the beam after the column and beam are installed. This can cause deformation or damage to the connection when the load on the clip exceeds its design bearing capacity. Therefore, a quick-install column-beam connection clip is proposed. Utility Model Content

[0006] The purpose of this utility model is to address the current problem that it is difficult to pre-fix the beam during the installation of the column and beam, which requires workers to hold the beam for a long time during installation, making it difficult to make the column-beam connection faster and more reliable.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a quick-install column-beam connecting buckle, comprising a column body, a connector provided on the outer surface of the column body, a beam body provided inside the connector, and an auxiliary device provided inside the connector;

[0009] The auxiliary device includes a through groove, which is formed on the side of the connector. A sliding groove is formed inside the connector, and a telescopic rod is fixedly connected inside the sliding groove. A locking block is fixedly connected to the telescopic end of the telescopic rod. A locking groove is formed on the top of the beam. A moving groove is formed on the front side of the connector. A connecting strip is fixedly connected to the top of the locking block, and the side of the connecting strip is slidably connected inside the moving groove.

[0010] As a preferred technical solution of this utility model, a rotating rod is fixedly connected to the inner wall of the moving groove, a baffle is rotatably connected to the circumferential surface of the rotating rod, and a stop block is slidably connected to the top of the connecting piece. The function of the baffle is to block the connecting strip and prevent the connecting strip from accidentally dislodging the locking block from the slot. The function of the stop block is to block the baffle.

[0011] As a preferred technical solution of this utility model, a return spring is fixedly connected to the inner wall of the slide groove. The end of the return spring away from the slide groove is fixedly connected to the telescopic end of the telescopic rod. The function of the return spring is to allow the block to be reset by the telescopic rod using the return spring when the beam no longer presses against the block.

[0012] As a preferred technical solution of this utility model, the shape of the card block is set to rectangle, and the side section of the card block is inclined. The side of the card block is located on the displacement trajectory of the beam. The purpose of setting the side section of the card block to be inclined is to enable the beam to better squeeze the card block to move.

[0013] As a preferred technical solution of this utility model, a support device is provided at the bottom of the column. The support device includes a threaded hole, which is opened on the side of the column. A connecting plate is provided on the side of the column. A bolt is threadedly connected to the inner wall of the connecting plate. A rotating shaft is rotatably connected to the side of the connecting plate. A hollow strip is rotatably connected to the circumference of the rotating shaft. A support strip is slidably connected to the inner wall of the hollow strip. A connecting shaft is rotatably connected to the side of the support strip. A support plate is rotatably connected to the circumference of the connecting shaft. The support plate is located at the bottom of the beam. The function of the hollow strip is to allow the support strip to slide inside.

[0014] As a preferred technical solution of this utility model, an elastic spring is fixedly connected to the inner wall of the hollow strip, and the end of the elastic spring away from the hollow strip is fixedly connected to the bottom of the support strip. The function of the elastic spring is to reduce the impact force of the support strip when the support strip moves into the hollow strip.

[0015] As a preferred technical solution of this utility model, the number of threaded holes and bolts is set to two, and they are arranged in a linear array along the vertical central axis of the hollow strip. The number of support devices is set to several, and they are distributed around the perimeter of the column. The purpose of setting two threaded holes and bolts is to allow the support plate to be installed on the beam.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Through the auxiliary device, when the beam is moved to the appropriate position, the locking block will be reset by the return spring because it is no longer squeezed by the beam, so that it can enter the slot to pre-fix the beam, which facilitates the installation of the column and the beam by the workers. After the pre-fixation is completed, the baffle and the stop block are reset to block the connecting strip. When it is necessary to make a fine adjustment to the distance of the beam, the baffle and the stop block can be opened again, and the locking block can be removed from the slot by the connecting strip, so that the beam can be fine-tuned.

[0018] 2. The support device allows bolts to be inserted into threaded holes, and connecting plates and support plates to be installed on columns and beams. This supports the beams and prevents the load on the clamping blocks from exceeding their design bearing capacity, which could lead to deformation or damage at the connection points. When the support bar moves into the hollow bar, it compresses the spring. As the support bar compresses the spring, the spring reduces the impact force of the support bar's swaying, thereby slowing down the swaying of the beam and increasing its stability.

[0029] like Figure 1 , Figure 2 , Figure 4 As shown, this embodiment proposes a quick-install column-beam connection buckle, including a column 1, a connector 2 provided on the outer surface of the column 1, a beam 3 provided inside the connector 2, and an auxiliary device 4 provided inside the connector 2.

[0030] The auxiliary device 4 includes a through groove 41, which is opened on the side of the connector 2. A sliding groove 42 is opened inside the connector 2.

The function of the stop block 410 is to block the baffle 49.

[0032] like Figure 2 , Figure 4 As shown, in a preferred embodiment, based on the above method, a return spring 411 is further fixedly connected to the inner wall of the slide groove 42. The end of the return spring 411 away from the slide groove 42 is fixedly connected to the telescopic end of the telescopic rod 43. The function of the return spring 411 is to reset the block 44 through the telescopic rod 43 using the return spring 411 when the beam 3 no longer presses the block 44.

[0033] like Figure 2 , Figure 4 As shown, in a preferred embodiment, based on the above method, the shape of the card block 44 is further set to a rectangle, and the side section of the card block 44 is an inclined plane. The side of the card block 44 is located on the displacement trajectory of the beam 3. The purpose of setting the side section of the card block 44 to an inclined plane is to enable the beam 3 to better squeeze the card block 44 to move.

[0034] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, a support device 5 is further provided at the bottom of the column 1. The support device 5 includes a threaded hole 51, which is opened on the side of the column 1. A connecting plate 52 is provided on the side of the column 1. A bolt 53 is threadedly connected to the inner wall of the connecting plate 52. A rotating shaft 54 ​​is rotatably connected to the side of the connecting plate 52. A hollow strip 55 is rotatably connected to the circumferential surface of the rotating shaft 54. A support strip 56 is slidably connected to the inner wall of the hollow strip 55. A connecting shaft 57 is rotatably connected to the side of the support strip 56. A support plate 58 is rotatably connected to the circumferential surface of the connecting shaft 57. The support plate 58 is provided at the bottom of the beam 3. The function of the hollow strip 55 is to allow the support strip 56 to slide inside.

[0035] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, a spring 59 is further fixedly connected to the inner wall of the hollow strip 55. The end of the spring 59 away from the hollow strip 55 is fixedly connected to the bottom of the support strip 56. The function of the spring 59 is to reduce the impact force of the support strip 56 when the support strip 56 moves into the hollow strip 55.

[0036] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, the number of threaded holes 51 and bolts 53 is further set to two, and they are arranged in a linear array along the vertical central axis of the hollow strip 55. The number of support devices 5 is set to several, and they are distributed around the column 1. The purpose of setting two threaded holes 51 and bolts 53 is to install the support plate 58 on the beam 3.

[0037] Specifically, when using this column-beam connection auxiliary device: First, when it is necessary to install the column 1 and the beam 3, the auxiliary device 4 can be used. By sliding the stop block 410 away from the baffle 49, and then rotating the baffle 49 upward away from the connecting strip 47 via the rotating rod 48, the beam 3 is aligned with the through groove 41 on the connector 2, and then the beam 3 is inserted into the through groove 41. When the beam 3 enters the through groove 41, it will contact the locking block 44. When the locking block 44 is pushed by the beam 3, it will use the pushing force of the beam 3 and its own inclined surface to squeeze the return spring 411 through the telescopic rod 43 and enter the slide groove 42. When the beam 3 moves to the appropriate position... When the beam 3 is not pressed, the locking block 44 will be reset by the return spring 411, so that it can enter the slot 45 to pre-fix the beam 3. This makes it easier for workers to install the column 1 and the beam 3, and the connection between the column 1 and the beam 3 can be faster and more reliable. After the pre-fixation is completed, the baffle 49 and the stop block 410 are reset to block the connecting strip 47. When it is necessary to make a fine adjustment to the distance of the beam 3, the baffle 49 and the stop block 410 can be opened again. The connecting strip 47 drives the locking block 44 to remove the slot 45, so that the beam 3 can be fine-tuned and the pre-fixed position can be avoided from deviating from the actual installation position.

[0038] The support device 5 provides support for the column 1 and beam 3. By aligning the connecting plate 52 and support plate 58 with the threaded holes 51 on the column 1 and beam 3, and then inserting the bolts 53 into the threaded holes 51, the connecting plate 52 and support plate 58 are installed on the column 1 and beam 3. This supports the beam 3 and prevents the load on the locking block 44 from exceeding its design bearing capacity, which could lead to deformation or damage at the connection point. When the beam 3 shakes, the support plate 58 will also use the connecting shaft 57 to drive the support bar 56 to move into the hollow bar 55. When the support bar 56 moves into the hollow bar 55, it will compress the spring spring 59. As the support bar 56 compresses the spring spring 59, the spring spring 59 will reduce the impact force of the support bar 56 shaking, thereby slowing down the shaking of the beam 3 and increasing the stability of the beam 3. This ensures that the column 1 and beam 3 will not loosen or shift during use.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
