Description

Technical Field

[0001] This application belongs to the field of steel structure construction, and more specifically, it relates to a quick-installation and fixing structure for steel structure beam-column joints. Background Technology

[0002] Steel beams and columns in steel structures are generally installed separately and then fixed to the steel columns through node structures during assembly. For example, Chinese patent publication CN114622649A discloses a quick-installation node installation and fixing structure for steel beams and columns. Specifically, the quick-installation node for steel beams and columns includes an upper clamping and fixing component and a lower clamping and fixing component installed at the end of the beam, and a first fixing and installation component and a second fixing and installation component fixedly installed on the column. The upper clamping and fixing component clamps and fixes the end of the upper beam plate, and the lower clamping and fixing component clamps and fixes the end of the lower beam plate. The end of the upper beam plate is quickly connected to the first fixing and installation component installed on the column through the upper clamping and fixing component, and the end of the lower beam plate is quickly connected to the second fixing and installation component installed on the column through the lower clamping and fixing component. This allows for quick fixing and installation of the beam on the column, improving the deflection resistance of the beam after installation.

[0003] However, in actual use, the aforementioned steel structure requires the connection of beams and columns through a first fixed installation assembly, a second fixed installation assembly, and a lower supporting fixed assembly.

[0026] The technical solutions described in this application will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0027] like Figures 1 to 7 As shown, the quick-installation joint fixing structure for steel beams and columns includes beams and columns 1. A top node 7 is provided on the top of beams and columns 1. The top node 7 is a rectangular shell with an internal accommodating space. The top node 7 has a clamping limit hole 12 and a positioning mounting hole 11 machined on the shell facing the crossbeam 14. The clamping limit hole 12 is distributed in the circumferential direction of the crossbeam connecting plate 13. The crossbeam connecting plate 13 is connected to the positioning mounting hole 11 by bolt fasteners.

[0028] A gripper 10 is slidably disposed inside the gripper limiting hole 12. Gripper side plates 9 are fixedly connected to both sides of the gripper 10, which is located above and below the crossbeam connecting plate 13. The gripper side plates 9 form a structure that supports the crossbeam connecting plate 13. A side plate guide block 20 is also provided at the bottom of the gripper side plate 9 located below the crossbeam connecting plate 13. The side plate guide block 20 is confined within the bottom guide seat 19. The bottom guide seat 19 is a pair of plates and is fixedly connected to the top node 7.

[0029] The gripper side plate 9 has a gripper inclined surface 40 on the bottom surface of the entrance facing the crossbeam connecting plate 13. The gripper inclined surface 40 is connected to the gripper slot 42 through the gripper transition plane 41 of the planar structure. The gripper slot 42 is a rectangular opening and is located outside the shell of the top node 7.

[0030] The gripper 10 has a gripper guide shaft 24 integrally provided at its end that extends into the top node 7 through the gripper limiting hole 12. The gripper guide shaft 24 is slidably connected in an arc-shaped drive hole 38. The arc-shaped drive hole 38 is an arc-shaped through hole or an arc-shaped blind hole, which can drive the gripper guide shaft 24 to move inside it as the gripper drive disk 25 rotates. Drive disk limiting plates 26 are provided on the top nodes 7 on both sides of the gripper drive disk 25. The drive disk limiting plates 26 are used to limit the rotation state of the gripper drive disk 25.

[0031] The gripper drive disk 25 is located on the disk body bearing seat 27, which is coaxially mounted on the node fixing sleeve 31. The two ends of the node fixing sleeve 31 are fixedly connected to the top node 7 at the corresponding positions.

[0032] The outer wall of the disc bearing seat 27 is machined with a gear tooth structure. A pressure plate 28 is suspended above the disc bearing seat 27. The pressure plate 28 is an arc-shaped plate, and its bottom surface is machined with a gear tooth structure. When the pressure plate 28 contacts the outer wall of the disc bearing seat 27, the gear teeth on both mesh and limit the position of the disc bearing seat 27. The pressure plate 28 and the pressure plate drive rod 29 are fixed together. The end of the pressure plate drive rod 29 closest to and furthest from the pressure plate 28 is hinged by a pressure rod hinge seat 30, which is located on the node fixing sleeve 31.

[0033] The end of the pressure plate drive rod 29 is driven by the rod drive ring 33, and the contact surface between the rod drive ring 33 and the pressure plate drive rod 29 is inclined. The rod drive ring 33 is sleeved on the node fixing sleeve 31, and the rod drive ring 33 is connected to the pressing drive shaft 32 through a connecting block and the sleeve opening 37 on the node fixing sleeve 31. The pressing drive shaft 32 is located in the cavity of the node fixing sleeve 31 and is coaxially arranged with the node fixing sleeve 31. A compression spring is provided between the pressing drive shaft 32 and the bottom surface of the cavity of the node fixing sleeve 31. The first end of the node fixing sleeve 31 is located in the node crimping hole 39. The node crimping hole 39 and the opening of the cavity of the node fixing sleeve 31 form a stepped hole.

[0034] The end face of the beam connecting plate 13 that contacts the top node 7 is machined with a connecting plate pressure block 22, and the cross-section of the connecting plate pressure block 22 is the same as the cross-sectional shape of the node pressing hole 39. Example 2

[0035] like Figures 1 to 7 As shown, the steel structure beam-column quick-assembly joint installation and fixing structure includes a jacking pipe 3 between the beam-column 1 and the top node 7. One end of the jacking pipe 3 is connected to the top node 7 via an upper flange 21, and the other end of the jacking pipe 3 is connected to the beam-column 1 via a bottom flange 2. The jacking pipe 3 has circumferential reinforcing bars 4 on its outer wall between the upper flange 21 and the bottom flange 2. Both ends of the circumferential reinforcing bars 4 are connected integrally to the upper flange 21 and the bottom flange 2, respectively.

[0036] The jacking pipe 3 is fitted with a jacking pipe hinge seat 5 on its outer wall via jacking pipe circumferential ribs 4. A jacking pipe support block 6 is provided at the connection position between the jacking pipe hinge seat 5 and the jacking pipe 3. The jacking pipe support block 6 is driven outward by a screw drive block 35 inside the jacking pipe 3. The screw drive blocks 35 are located at both ends of the screw 34 inside the pipe and are respectively connected to two opposite threads on the screw 34 inside the pipe. The two ends of the screw 34 inside the pipe are connected to the plates at both ends of the jacking pipe 3 via bearing structures. The end of the screw 34 inside the pipe that extends out of the bottom flange 2 of the jacking pipe is connected to a screw adjustment end 36, which is a polygonal block. An outer diagonal brace 18 is hinged to the jacking pipe hinge seat 5. An inner diagonal brace 17 is inserted inside the outer diagonal brace 18. The outer diagonal brace 18 and the inner diagonal brace 17 have connecting through holes along their length and are connected to bolt fasteners through the connecting through holes. The inner rod 17 of the diagonal brace is hinged to the hinge seat 15 of the crossbeam. The hinge seat 15 is connected to the outer wall of the crossbeam rib 16 through the crossbeam 14. A hinge seat connection hole 23 is machined through the top of the hinge seat 15. The hinge seat connection hole 23 is connected to the crossbeam rib 16 on the crossbeam 14 by fastening bolts, thereby fixing the hinge seat connection hole 23. The structure and connection relationship of the remaining parts are the same as those described in any of the foregoing embodiments. To avoid cumbersome description, they will not be repeated here. Example 3

[0037] like Figures 1 to 7 As shown, the quick-installation node fixing structure for steel structure beams and columns has toothed or toothed contact surfaces on the jacking pipe support block 6 and the jacking pipe hinge seat 5. The structure and connection relationship of the remaining parts are the same as those described in any of the aforementioned embodiments. To avoid cumbersome descriptions, they will not be repeated here.

[0038] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0039] During the connection process between the crossbeam connecting plate 13 and the top node 7, that is, during the insertion of the crossbeam connecting plate 13 into the space formed by the gripper 10 on the top node 7, the circumferential end face of the crossbeam connecting plate 13 can contact the inclined surface 40 of the gripper body of the gripper 10, causing the gripper 10 to expand outward. During the outward expansion process, the gripper 10 can move along the gripper limiting hole 12 on the top node 7.

[0040] As the gripper 10 moves outward along the gripper limiting hole 12, the gripper guide shaft 24, integrally formed with the gripper 10 and located within the top node 7, can move within the arc-shaped drive hole 38. During its movement within the arc-shaped drive hole 38, the gripper guide shaft 24 forces the gripper drive disk 25 to rotate, thereby rotating the disk bearing seat 27. The disk bearing seat 27 rotates around the node fixing sleeve 31. As a preferred technical solution, a torsion spring structure can be provided at the connection point between the disk bearing seat 27 and the node fixing sleeve 31, thereby achieving a certain restoring force or rotational damping.

[0041] The end face of the crossbeam connecting plate 13 passes through the claw body inclined surface 40 and the claw body transition plane 41 in sequence before entering the claw body slot 42. After the crossbeam connecting plate 13 enters the claw body slot 42, the gripper 10 can be reset inward by a certain distance. The torsion spring structure makes the above reset action smoother.

[0042] After the crossbeam connecting plate 13 is engaged by the claw body latch 42, the connecting plate pressure block 22 on the end face of the crossbeam connecting plate 13 is inserted into the corresponding node pressing hole 39, and during the insertion into the node pressing hole 39, the pressing drive shaft 32 located in the node pressing hole 39 is forced to move inward.

[0043] The pressure drive shaft 32 moves inward along the hollow cavity of the node fixing sleeve 31 and compresses the compression spring at the bottom. During the movement of the pressure drive shaft 32 into the node fixing sleeve 31, it can push the rod drive ring 33 to move through the connecting block. The rod drive ring 33 pushes the end of the pressure plate drive rod 29 outward relative to the node fixing sleeve 31 through the inclined surface. During the outward expansion of the pressure plate drive rod 29, the pressure plate drive rod 29 can rotate around the pressure rod hinge seat 30. At the end of the pressure plate drive rod 29 connected to the pressure plate body 28, the pressure plate drive rod 29 drives the pressure plate body 28 to approach the disc bearing seat 27 and engages with the disc bearing seat 27 through the gear tooth structure, thereby achieving the limiting of the disc bearing seat 27.

[0044] Meanwhile, the pressure drive shaft 32 and the compression spring it compresses can cooperate with the claw body slot 42 to improve the locking stability of the crossbeam connecting plate 13. The opening width of the claw body slot 42 is close to the thickness of the crossbeam connecting plate 13.

[0045] The crossbeam 14 is also provided with a crossbeam rib 16 for strengthening its own structural strength and for guiding the crossbeam hinge seat 15. The crossbeam hinge seat 15 is connected to the crossbeam rib 16 through the hinge seat connection hole 23 and fastening bolts without affecting the strength of the crossbeam 14 itself.

[0046] The beam-column 1 and the top node 7 are connected and fixed by a jacking pipe 3 structure to achieve the jacking pipe hinge seat 5. The jacking pipe hinge seat 5 is connected to and guided by the jacking pipe 3 through the circumferential reinforcement 4. The jacking pipe 3 is connected to the jacking pipe hinge seat 5 through the jacking pipe support block 6. The jacking pipe support block 6 moves outward under the action of the screw drive block 35 that moves relatively within the jacking pipe 3 and is connected to the jacking pipe hinge seat 5 through a gear structure or a tooth structure.

[0047] An inner diagonal brace 17 and an outer diagonal brace 18 are respectively provided between the crossbeam hinge seat 15 and the jacking pipe hinge seat 5. The inner diagonal brace 17 and the outer diagonal brace 18 are inserted into each other and fixed by connecting through holes and fastening bolts.

[0048] The inner diagonal brace 17 and the outer diagonal brace 18 form a diagonal bracing structure between the crossbeam 14 and the jacking pipe 3 to enhance the stability and strength of the connection position.

[0049] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
