Description

Technical Field

[0001] This invention relates to the field of prefabricated beam-column technology, and in particular to a prefabricated beam-column joint structure and construction method. Background Technology

[0002] Prefabricated building technology can effectively shorten the construction period and improve construction efficiency, and is an important component of the new construction industry.

[0003] In existing technologies, such as Chinese Patent CN112681518B, a prefabricated beam-column joint connection device for steel structures is disclosed. This device includes several columns and beams for connecting each other. The columns, beams, and columns are all fixedly connected via connecting boxes. At least two of the six directions of the connecting box have box-shaped connectors, each with at least one opening. At least one inner surface of the box-shaped connector has a guide rail. This patent modularizes the components, connecting them on-site using bolts. The beams, columns, and joint connectors form the overall structure. Since the beams and columns are all straight rods, transportation space is significantly reduced, effectively saving transportation costs.

[0004] In the above technical solution, workers use connecting boxes, box-type connectors, bolts, and nuts to stabilize the beam on the column. However, in order to ensure the stability of the box-type connectors, a large number of bolts and nuts are required. This setup requires a lot of labor from the workers, prolongs the installation time of the beam-column joint, and reduces the installation efficiency of the beam-column joint.

[0005] Based on this, a prefabricated beam-column joint structure and construction method are proposed. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a prefabricated beam-column joint structure and its construction method.

[0007] The technical solution for achieving the purpose of this invention is: a prefabricated beam-column joint structure, including a connecting cavity, wherein a first horizontal beam, a second horizontal beam, and a vertical beam are respectively arranged inside the connecting cavity, and further comprising:

[0008] An assembly assembly, the assembly assembly including a force-supporting unit and a fastening unit;

[0009] The force-bearing auxiliary unit includes two rotating limiting plates. A sealing cylinder is rotatably connected to one side of each of the two rotating limiting plates. A tension piston rod is slidably connected to the inner wall of each of the two sealing cylinders. A moving block is rotatably connected to one end of each of the two tension piston rods. The two moving blocks are slidably disposed on the inner walls of crossbeam one and crossbeam two, respectively.

[0010] The fastening unit includes an adapter plate, on the upper surface of which multiple positioning rods are fixedly connected. Multiple positioning holes are provided on both sides of the connecting cavity. The inner walls of the multiple positioning holes are slidably connected to the surfaces of the corresponding multiple positioning rods. One end of the first crossbeam and the second crossbeam are respectively fixedly connected to an arc-shaped block and an arc-shaped block. The opposite surfaces of the first arc-shaped block and the second arc-shaped block are respectively provided with a groove 2, a slot 2, a groove 1, and a slot 1. A coil spring shaft 1 is provided on the inner wall of the groove 1. A hook 1 is fixedly installed on the surface of the coil spring shaft 1. A gear 1 is fixedly connected to one end of the coil spring shaft 1.

[0011] Preferably, the force-supporting unit further includes a vent pipe fixedly connected to the surface of the sealing cylinder, a threaded cylinder fixedly connected to the inner wall of the vent pipe, a screw cap detachably connected to the inner wall of the threaded cylinder, a sealing ring fixedly connected to the surface of the screw cap, a spring fixedly connected to the inner wall of the sealing cylinder, and one end of the spring fixedly connected to one end of the tension piston rod.

[0012] Preferably, both sides of the vertical beam are fixedly connected to limit groove plates, the surface of the limit rotating plate is slidably connected to the inner wall of the limit groove plate, the inner walls of the first and second horizontal beams are provided with sliding grooves, and the surfaces of the two moving blocks are respectively slidably connected to the inner walls of the corresponding two sliding grooves.

[0013] Preferably, the fastening unit further includes a coil spring shaft II disposed on the inner wall of the groove II, a hook II fixedly mounted on the surface of the coil spring shaft II, and a gear II fixedly connected to one end of the coil spring shaft II.

[0014] Preferably, a connector is fixedly connected to the lower surface of the adapter plate, and rectangular cavity one and rectangular cavity two are fixedly connected to the lower surface of the connector respectively. The inner walls of rectangular cavity one and rectangular cavity two are rotatably connected with multiple arc-shaped teeth through one-way bearings.

[0015] Preferably, the lower surface of the connector is fixedly connected with a plug, and a slot is provided on one side of both the first arc-shaped block and the second arc-shaped block, and the surface of the plug is adapted to slide and connect with the inner wall of the slot.

[0016] Preferably, the surfaces of hook one and hook two are adapted to slide and connect with the inner walls of the corresponding slots one and slot two, respectively, and gear one and gear two are respectively engaged with the arc-shaped teeth rotatably arranged on the inner walls of the corresponding rectangular cavities one and two.

[0017] A prefabricated beam and column construction method, comprising the following steps:

[0018] S1: First, insert crossbeam one and crossbeam two into the connecting cavity. This allows hook one and hook two to rotate under the action of coil spring shaft one and coil spring shaft two, respectively. When the slot two on arc block one corresponds to hook one, and at the same time, the slot one on arc block two corresponds to hook two, hook one and hook two are respectively inserted into slot one and slot two, thus achieving a quick and tight connection between crossbeam one and crossbeam two inside the connecting cavity.

[0019] S2: After the first and second crossbeams are assembled, the vertical beam is hoisted and lowered vertically into the top of the connecting cavity. The vertical beam can be pre-fixed by the cooperation of the positioning hole and the positioning rod. After the positioning rod is inserted into the positioning hole, the insert block at the bottom of the adapter plate is inserted into the slot at the same time, which can further fix the vertical beam.

[0020] S3: Next, by rotating the screw cap on the vent pipe, the vent pipe and the sealing cylinder are connected. The rotating limit plate is inserted into the limit groove plate. At this time, the moving block slides to the end of the slide groove, which can prevent the moving block from sliding further. At the same time, the screw cap is tightened to seal the sealing cylinder, which can fix the tension piston rod inside the sealing cylinder, thus completing the assembly work.

[0021] Compared with the prior art, the present invention has the following significant advantages:

[0022] Firstly, this invention inserts two crossbeams into the connecting cavity. When the arc-shaped end of the arc-shaped block one contacts the arc surface of the hook one, the arc-shaped end of the arc-shaped block two simultaneously contacts the arc surface of the hook two. This allows the hooks one and two to rotate under the action of the coil spring shaft one and the coil spring shaft two, respectively, thus avoiding the arc-shaped block one and the arc-shaped block. When the slot two on the arc-shaped block one corresponds to the hook one, the hook one, under the reset of the coil spring shaft one, achieves engagement with the slot two. At the same time, when the slot one on the arc-shaped block two corresponds to the hook two, the hook two, under the reset of the coil spring shaft two, achieves engagement with the slot one. This allows for a rapid and secure connection between the crossbeam one and the crossbeam two inside the connecting cavity. The mechanical meshing achieves instantaneous locking of the crossbeam one and the crossbeam two, replacing the traditional bolt connection, and is simple and convenient to operate.

[0023] Secondly, the present invention can achieve pre-fixation of the vertical beam through the cooperation of positioning holes and positioning rods. After the positioning rod is inserted into the positioning hole, the plug at the bottom of the adapter plate is simultaneously inserted into the slot, which can further fix the vertical beam. This can achieve rapid pre-fixation of the vertical beam and improve the ease of installation.

[0024] Thirdly, this invention achieves communication between the vent pipe and the sealing cylinder by rotating the screw cap on the vent pipe. At this time, the tension piston rod can slide inside the sealing cylinder. The sliding of the sealing cylinder can provide motion compensation for the limiting position between the rotating limiting plate and the limiting groove plate. When the rotating limiting plate is inserted into the limiting groove plate, the moving block slides to the end of the groove, which can prevent the moving block from sliding further. At the same time, tightening the screw cap can seal the sealing cylinder and fix the tension piston rod inside the sealing cylinder. This can improve the stability after connection while achieving quick connection. Attached Figure Description

[0035] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0036] This invention provides an improved prefabricated beam-column joint structure. The technical solution of this invention is as follows:

[0037] like Figures 1-7 As shown, a prefabricated beam-column joint structure and construction method include a connecting cavity 1, wherein a first horizontal beam 2, a second horizontal beam 3, and a vertical beam 5 are respectively arranged inside the connecting cavity 1, and further include:

[0038] Assembly components, which include force-supporting units and fastening units;

[0039] The force-bearing auxiliary unit includes two rotating limiting plates 13. Each of the two rotating limiting plates 13 is rotatably connected to a sealing cylinder 9 on one side. Each of the two sealing cylinders 9 is slidably connected to a tension piston rod 10 on the inner wall. Each of the two tension piston rods 10 is rotatably connected to a moving block 8 at one end. The two moving blocks 8 are slidably disposed on the inner walls of the first beam 2 and the second beam 3, respectively.

[0040] The fastening unit includes an adapter plate 4, on the upper surface of which multiple positioning rods 14 are fixedly connected. Multiple positioning holes 15 are provided on both sides of the connecting cavity 1. The inner walls of the multiple positioning holes 15 are slidably connected to the surfaces of the corresponding multiple positioning rods 14. One end of the crossbeam 1 2 and the crossbeam 2 3 are respectively fixedly connected to an arc-shaped block 1 20 and an arc-shaped block 2 21. The opposite surfaces of the arc-shaped block 1 20 and the arc-shaped block 2 21 are respectively provided with a groove 2 32, a slot 2 36, a groove 1 27, and a slot 1 31. The inner wall of 27 is provided with a coil spring shaft 28. A hook 30 is fixedly installed on the surface of the coil spring shaft 28. A gear 29 is fixedly connected to one end of the coil spring shaft 28. When the slot 36 on the arc block 20 corresponds to the hook 30, and at the same time the slot 31 on the arc block 21 corresponds to the hook 35, the hook 30 and the hook 35 are respectively inserted into the slot 31 and the slot 36, so as to realize the quick and tight connection between the crossbeam 2 and the crossbeam 3 inside the connecting cavity 1.

[0041] like Figure 2 and Figure 3As shown, the force-supporting unit also includes a vent pipe 12 fixedly connected to the surface of the sealing cylinder 9. A threaded cylinder 16 is fixedly connected to the inner wall of the vent pipe 12. A screw cap 17 is detachably connected to the inner wall of the threaded cylinder 16. A sealing ring 18 is fixedly connected to the surface of the screw cap 17. A spring 11 is fixedly connected to the inner wall of the sealing cylinder 9. One end of the spring 11 is fixedly connected to one end of the tension piston rod 10. Through the cooperation of the screw cap 17 and the threaded cylinder 16, the vent pipe 12 and the sealing cylinder 9 can be connected, thereby enabling the tension piston rod 10 to slide inside the sealing cylinder 9.

[0042] Both sides of the vertical beam 5 are fixedly connected to limit groove plates 6. The surface of the limit rotating plate is slidably connected to the inner wall of the limit groove plate 6. The inner walls of the first horizontal beam 2 and the second horizontal beam 3 are provided with sliding grooves 7. The surfaces of the two moving blocks 8 are slidably connected to the inner walls of the corresponding two sliding grooves 7 respectively.

[0043] like Figure 6 and Figure 7 As shown, the fastening unit also includes a coil spring shaft 33 disposed on the inner wall of the groove 32. A hook 35 is fixedly installed on the surface of the coil spring shaft 33. A gear 34 is fixedly connected to one end of the coil spring shaft 33. The coil spring shaft 28 and the coil spring shaft 33 are existing technologies and will not be described in detail here.

[0044] The lower surface of the adapter plate 4 is fixedly connected to a connector 22. The lower surface of the connector 22 is fixedly connected to a rectangular cavity 1 24 and a rectangular cavity 25 respectively. The inner walls of the rectangular cavity 1 24 and the rectangular cavity 25 are rotatably connected to multiple arc-shaped teeth 26 through one-way bearings. With the setting of one-way bearings, the vertical beam 5 can be lifted first during disassembly. At this time, the arc-shaped teeth 26 will drive the gear 1 29 and the gear 2 34 to rotate, thereby realizing the disengagement between the hook 1 30 and the hook 2 35 and the slot 1 31 and the slot 2 36, thereby realizing the quick disassembly between the cross beam 1 2 and the cross beam 2 3. After the cross beam 1 2 and the cross beam 2 3 are disassembled, the vertical beam 5 is completely lifted for disassembly.

[0045] The lower surface of the connector 22 is fixedly connected with a plug 23. One side of the arc-shaped block 20 and the arc-shaped block 21 is provided with a slot 19. The surface of the plug 23 is adapted to slide and connect with the inner wall of the slot 19. Through the cooperation of the slot 19 and the plug 23, the arc-shaped block 20 and the arc-shaped block 21 can be prevented from shifting in the lateral direction. The weight of the vertical beam 5 can be used to further limit the horizontal beam 2 and the horizontal beam 3.

[0046] The surfaces of hook 1 30 and hook 2 35 are adapted to slide and connect with the inner walls of corresponding slot 1 31 and slot 2 36, respectively. The engagement of slot 1 31 and slot 2 36 can lock hook 1 30 and hook 2 35, thereby enabling the rapid assembly of arc block 1 20 and arc block 2 21. Gear 1 29 and gear 2 34 mesh with the arc teeth 26 rotatably set on the inner walls of corresponding rectangular cavity 1 24 and rectangular cavity 2 25, respectively. Through the arc teeth 26, when the vertical beam 5 is pre-fixed, the arc teeth 26 can be lowered without driving gear 1 29 and gear 2 34 to rotate.

[0047] A prefabricated beam and column construction method, comprising the following steps:

[0048] S1: First, insert crossbeam 1 2 and crossbeam 2 3 into the connecting cavity 1. This allows hook 1 30 and hook 2 35 to rotate under the action of spring shaft 1 28 and spring shaft 2 33, respectively. When the slot 2 36 on arc block 1 20 corresponds to hook 1 30, and at the same time, the slot 1 31 on arc block 2 21 corresponds to hook 2 35, hook 1 30 and hook 2 35 are respectively inserted into slot 1 31 and slot 2 36, thus achieving a quick and tight connection between crossbeam 1 2 and crossbeam 2 3 inside the connecting cavity 1.

[0049] S2: After the crossbeam 1 2 and crossbeam 2 3 are assembled, the vertical beam 5 is hoisted and lowered vertically into the top of the connecting cavity 1. The vertical beam 5 can be pre-fixed by the cooperation of the positioning hole 15 and the positioning rod 14. After the positioning rod 14 is inserted into the positioning hole 15, the insert block 23 at the bottom of the adapter plate 4 is inserted into the slot 19 at the same time, which can further fix the vertical beam 5.

[0050] S3: Next, by rotating the screw cap 17 on the vent pipe 12, the vent pipe 12 and the sealing cylinder 9 are connected. The rotating limiting plate 13 is inserted into the limiting groove plate 6. At this time, the moving block 8 slides to the end of the slide groove 7, which can prevent the moving block 8 from continuing to slide. At the same time, the screw cap 17 is tightened to seal the sealing cylinder 9, which can fix the tension piston rod 10 inside the sealing cylinder 9, thereby completing the assembly work.

[0051] The specific working method is as follows: During use, firstly, insert crossbeam 1 (2) and crossbeam 2 (3) into the connecting cavity 1. At this time, arc-shaped blocks 1 (20) and 21 (21) will slide alternately inside the connecting cavity 1. When the arc-shaped end of arc-shaped block 1 (20) contacts the arc surface of hook 1 (30), simultaneously, the arc-shaped end of arc-shaped block 21 (21) contacts the arc surface of hook 2 (35). This allows hook 1 (30) and hook 2 (35) to rotate under the action of coil spring shaft 1 (28) and coil spring shaft 2 (33), respectively, thus avoiding arc-shaped blocks 1 (20) and 21. When the slot 2 (36) on arc-shaped block 1 (20)... When corresponding to the first hook 30, the first hook 30 is reset by the first spring shaft 28 and engages with the second slot 36. At the same time, when the second slot 31 on the second arc block 21 is corresponding to the second hook 35, the second hook 35 is reset by the second spring shaft 33 and engages with the first slot 31. This enables the first beam 2 and the second beam 3 to be quickly and securely connected inside the connecting cavity 1. After connection, the arc-shaped end faces of the first arc block 20 and the second arc block 21 abut against the inner wall of the connecting cavity 1, which can prevent the first beam 2 and the second beam 3 from continuing to slide, thus affecting the connection stability.

[0052] After the crossbeam 1 2 and crossbeam 2 3 are assembled, the vertical beam 5 is hoisted and lowered vertically into the top of the connecting cavity 1. The vertical beam 5 can be pre-fixed through the cooperation of the positioning hole 15 and the positioning rod 14. After the positioning rod 14 is inserted into the positioning hole 15, the insert block 23 at the bottom of the adapter plate 4 is simultaneously inserted into the slot 19, which can further fix the vertical beam 5. During the process of inserting the insert block 23 into the slot 19, the arc-shaped teeth 26 set by the one-way bearing inside the rectangular cavity 1 24 and rectangular cavity 2 25 will not drive the gear 1 29 and gear 2 34 to rotate. When the insert block 23 is fully inserted into the slot 19, the arc-shaped teeth 26 mesh with the gear 1 29 and gear 2 34.

[0053] After the vertical beam 5 is assembled with the connecting cavity 1, the connection between the vent pipe 12 and the sealing cylinder 9 can be achieved by rotating the screw cap 17 on the vent pipe 12. At this time, the tension piston rod 10 can slide inside the sealing cylinder 9. The sliding of the sealing cylinder 9 can provide motion compensation for the limiting between the rotating limiting plate 13 and the limiting groove plate 6. When the rotating limiting plate 13 is inserted into the limiting groove plate 6, the moving block 8 slides to the end of the slide groove 7, which can prevent the moving block 8 from continuing to slide. At the same time, tightening the screw cap 17 can seal the sealing cylinder 9 and fix the tension piston rod 10 inside the sealing cylinder 9. Through the cooperation of the sealing cylinder 9, the tension piston rod 10, the vent pipe 12 and the screw cap 17, the tension between the vertical beam 5 and the first and second horizontal beams 2 and 3 can be achieved, thereby further improving the stability of the assembly.

[0054] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
