Description
Technical Field
[0001] This application relates to the technical field of steel structures, and in particular to a reinforced steel structure for steel structure joints. Background Technology
[0002] Steel structure joints refer to the parts in a steel structure building where different structural components connect to each other, including connections between beams, beams and columns, and columns and foundations.
[0003] Existing reinforcement structures at the connection between beams and columns in steel structures typically involve hinged connecting plates on both sides of the expansion joint, locking these plates to the beam and column respectively to support the beam. However, in situations where... Figure 1 When a curved beam is supported, the connecting plate does not easily adapt to the curvature of the curved beam, which easily leads to a large stress concentration at the connection point, affecting the supporting effect of the reinforced structure on the beam. Summary of the Invention
[0004] To improve the support effect on the curved beam, this application provides a reinforced steel structure at the joint of the steel structure.
[0005] This application provides a reinforced steel structure for steel structure joints, employing the following technical solution:
[0006] A reinforced steel structure for steel structure joints includes a first connecting assembly, a second connecting assembly, and telescopic support rods. The first connecting assembly includes multiple hinge plates, which are sequentially hinged and used for installation to the bottom of a beam. The second connecting assembly is used for installation to a column. The telescopic support rods are hinged at their far ends to the hinge plates and the second connecting assembly, respectively. There are multiple telescopic support rods, and each hinge plate is connected to at least one telescopic support rod.
[0007] By adopting the above technical solution, the column supports the beam through the hinge between the hinge plates and the telescopic support rods, reducing beam deformation and improving the load-bearing capacity of the structure. The angle between the hinge plates can be deformed according to the curvature of the beam, allowing the first connecting component to better adapt to the curvature of the curved beam, reducing stress concentration. In addition, multiple telescopic support rods can provide more uniform support force, improve the stability of the structure, and enhance the support effect on the curved beam.
[0008] Optionally, in two adjacent hinge plates, a hinge shaft that rotates on the hinge plate on the side away from the second connecting component is fixed on the hinge plate on the side closer to the second connecting component, and a rubber sleeve is fitted on the hinge shaft.
[0009] The first connecting assembly further includes a sliding seat and a first fixed seat. The first fixed seat is disposed on the hinge plate at the edge of the first connecting assembly and away from the second connecting assembly. The sliding seats are distributed on the remaining hinge plates except for the one with the first fixed seat. The sliding direction of the sliding seats is parallel to the axis of the hinge shaft. The sliding seats on the hinge plates are opposite to the hinge shaft rotating on the hinge plate itself. Both the sliding seats and the first fixed seat are used to hinge the telescopic support rods on the corresponding hinge plates.
[0010] The second connecting assembly includes a mounting base, a movable base, and a second fixed base. The mounting base is used to mount onto the column. Multiple movable bases slide on the mounting base. Each movable base corresponds to one of the remaining telescopic support rods (excluding those connected to the first fixed base) and is used to hinge the telescopic support rods. The distribution direction and sliding direction of the movable bases are parallel to the hinge axis. The mounting base has a driving assembly for driving the movable bases to slide, so that when the movable bases move, the telescopic support rods can drive the sliding bases to move in the direction of compressing the rubber sleeve. The second fixed base is fixed to the mounting base and is used to hinge the telescopic support rods connected to the first fixed base.
[0011] By adopting the above technical solution, the driving component drives the moving seat to move, which in turn causes the sliding seat to move and squeeze the rubber sleeve. The friction between the sliding seat and the rubber sleeve limits the rubber sleeve and prevents the hinge shaft from rotating relative to the sliding seat, thereby improving the stability between the hinge plates.
[0012] Optionally, the drive assembly includes a threaded rod and an adjusting member. The mounting base has a movable cavity. The threaded rod rotates on the mounting base and is located in the movable cavity. The movable base slides in the movable cavity and is threaded onto the outer wall of the threaded rod. The second fixed seat is located in the movable cavity and rotates onto the outer wall of the threaded rod. The adjusting member cooperates with the threaded rod and the mounting base so that the adjusting member can drive the threaded rod to lock together on the mounting base, or drive the threaded rod to release the lock from the mounting base and rotate.
[0013] By adopting the above technical solution, the threaded rod can be repeatedly rotated by locking and unlocking the adjusting component and the mounting base, thereby improving the convenience of adjusting the position of the moving base.
[0014] Optionally, the adjusting component includes a through rod, a locking head, and an adjusting ring. The through rod is slidably inserted coaxially into the threaded rod and the mounting base along the axial direction of the threaded rod. The locking head is disposed at one end of the through rod. The adjusting ring is threadedly connected to the other end of the through rod and located on the outer wall of the mounting base. Locating keys are evenly distributed on the outer circumference of the locking head. The mounting base has a locating groove at the end opposite to the locking head for the locking head and the locating keys to be engaged together. A limiting key is provided on the outer wall of the through rod opposite to the threaded rod. The inner cavity of the threaded rod has a limiting groove for the limiting key to slide along the axial direction of the threaded rod.
[0015] By adopting the above technical solution, the movement direction of the through rod is guided by the cooperation of the limit key and the limit groove. When the locking head is disengaged from the mounting base, it can drive the threaded rod to rotate through the through rod. When the locking head is locked with the mounting base by the positioning key, the rotation of the locking head relative to the mounting base is restricted. When the locking head is locked with the mounting base, the adjusting ring moves to press against the end wall of the mounting base to restrict the displacement of the locking head and improve the stability of the locking head.
[0016] Optionally, each hinge plate with the sliding seat has two sliding seats, and the rubber sleeve corresponds one-to-one with the sliding seat. The distance between the two sliding seats on each hinge plate gradually decreases in the direction away from the mounting base.
[0017] By adopting the above technical solution, the distance between the sliding seats of each hinge plate is different, making it less likely for the telescopic support rods extending from the sliding seats to interfere.
[0018] Optionally, the two rubber sleeves on the hinge plate are located between the two sliding seats, the threaded rod is a bidirectional screw, the threaded rod has a forward rotation part and a reverse rotation part with opposite threads, and the two movable seats on the hinge plate, which are connected by the telescopic support rod, are respectively threaded to the forward rotation part and the reverse rotation part.
[0019] By adopting the above technical solution, when the threaded rod rotates, the two corresponding moving seats on the hinge plate move towards or away from each other, thereby improving the overall stability of the reinforced steel structure.
[0020] Optionally, the rubber sleeve has an inclined surface that the sliding seat abuts against, the inclined surface gradually tilting towards the sliding seat along the direction in which the sliding seat presses against the rubber sleeve.
[0021] By adopting the above technical solution, the inclined surface can guide the sliding seat, causing the sliding seat to gradually squeeze the rubber sleeve.
[0022] Optionally, one end of the telescopic support rod is hinged to the sliding seat and located at the bottom of the sliding seat. The bottom of the hinge plate has a first support seat corresponding to the sliding seat. The first support seat has a first rubber layer that is hinged to the telescopic support rod at one end of the sliding seat. When the sliding seat squeezes the rubber sleeve, it drives the telescopic support rod to squeeze the first rubber layer.
[0023] By adopting the above technical solution, when the telescopic support rod compresses the first rubber layer, it can limit the relative position between the telescopic support rod and the first rubber layer, thereby improving the stability of the telescopic support rod.
[0024] Optionally, one end of the telescopic support rod is hinged to the movable seat and located outside the mounting base. The outer wall of the mounting base is provided with a second support seat corresponding to the movable seat. The second support seat has a second rubber layer facing the end of the telescopic support rod that is hinged to the movable seat. When the sliding seat squeezes the rubber sleeve, it drives the telescopic support rod to squeeze the second rubber layer.
[0025] By adopting the above technical solution, when the telescopic support rod compresses the second rubber layer, it can limit the relative position between the telescopic support rod and the second rubber layer, thereby improving the stability of the telescopic support rod.
[0026] Optionally, each of the telescopic support rods includes a sliding sleeve, a screw, and a locking ring. The screw slides in the sliding sleeve along its own axis. The locking ring is threaded to the outer wall of the screw to abut against the end of the sliding sleeve. The end of the screw away from the sliding sleeve is hinged to the sliding seat or the first fixed seat. The end of the sliding sleeve away from the screw is hinged to the moving seat or the second fixed seat.
[0027] In summary, this application includes at least the following beneficial effects:
[0028] By hinged together, the hinged plates can be installed on the beam to adapt to the curvature of the beam, thereby reducing stress concentration and improving the support effect on the curved beam. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0040] This application discloses a reinforced steel structure for steel structure joints. (Refer to...) Figure 2 The reinforcing steel structure at the joint of the steel structure includes a first connecting component 1, a second connecting component 2, and a telescopic support rod 3. The first connecting component 1 is used to be installed at the bottom of the beam, and the second connecting component 2 is used to be installed at the side of the column. The two ends of the telescopic support rod 3 that are far apart from each other are respectively hinged to the first connecting component 1 and the second connecting component 2 to reinforce the joint between the beam and the column.
[0041] Reference Figure 1 and Figure 2Each telescopic support rod 3 includes a sliding sleeve 31, a screw 32, and a locking ring 33. The sliding sleeve 31 is a cylindrical shape with one end open. The screw 32 slides coaxially in the sliding sleeve 31. One end of the screw 32 extends out of the sliding sleeve 31 from the opening of the sliding sleeve 31. The locking ring 33 is threaded onto the part of the screw 32 that extends out of the sliding sleeve 31. The locking ring 33 is used to abut against the end of the sliding sleeve 31 near the screw 32 to restrict the screw 32 from moving into the sliding sleeve 31.
[0042] Reference Figure 2 and Figure 4 The first connecting assembly 1 includes a hinge plate 101, a sliding seat 102, and a first fixed seat 103. The hinge plate 101 is square and there are multiple hinge plates 101, which are hinged sequentially. The multiple hinge plates 101 are distributed along the length extension direction of the beam and are locked to the beam by bolts. Specifically, in two adjacent hinge plates 101, the hinge plate 101 away from the second connecting component 2 has an integrally formed hinge seat 20 protruding from the hinge plate 101. The hinge plate 101 near the second connecting component 2 has a mounting groove for the hinge seat 20 to abut and rotate. The hinge seat 20 is provided with a hinge shaft 4 fixed on the hinge seat 20. The length direction of the hinge shaft 4 is parallel to the length direction of the hinge plate 101 and perpendicular to the distribution direction of the multiple hinge plates 101. The two ends of the hinge shaft 4 that are far apart from each other extend from the opposite ends of the hinge seat 20 and are rotatably connected to the hinge plate 101 near the second connecting component 2, so that the two adjacent hinge plates 101 are hinged, and the extension length of the hinge shaft 4 is consistent with the extension length of the hinge plate 101.
[0043] Reference Figure 2 and Figure 5 The first fixing seat 103 corresponds to the hinge plate 101 furthest from the second connecting component 2 among all the hinge plates 101, and the first fixing seat 103 is fixed at the center of the lower surface of the corresponding hinge plate 101. There are multiple sliding seats 102, each sliding seat 102 corresponding to the other hinge plates 101 except for the hinge plate 101 with the first fixing seat 103. The sliding seat 102 slides along the length direction of the hinge plate 101 on the corresponding hinge plate 101. The hinge plate 101 is provided with a sliding groove 21 that corresponds one-to-one with the sliding seat 102 for the sliding seat 102 to slide. The sliding groove 21 passes through the lower surface of the hinge plate 101. The sliding seat 102 is square and opposite to the hinge shaft 4. In order to restrict the sliding seat 102 from sliding down the sliding groove 21 to the hinge plate 101, a dovetail-shaped first anti-detachment block 22 is fixed on the side of the sliding seat 102 away from the hinge shaft 4 and on the top of the sliding seat 102. The hinge plate 101 has a first anti-detachment groove on the top wall and side wall of the sliding groove 21, which allows the limiting block to slide along the length direction of the hinge plate 101.
[0044] Reference Figure 2 and Figure 6Each hinge plate 101 with a sliding seat 102 has two sliding seats 102, which are distributed along the length of the hinge plate 101 and are symmetrically arranged along the hinge seat 20. The sliding seat 102 and the first fixed seat 103 each correspond one-to-one with the telescopic support rod 3 and are used to hinge with the end of the screw 32 located outside the sliding sleeve 31. Both the sliding seat 102 and the first fixed seat 103 have a portion extending downward from the lower surface of the hinge plate 101 for hinge with the end of the screw 32.
[0045] Reference Figure 5 The hinge plate 101 has a rotating cavity 23 corresponding to its own sliding seat 102. The rotating cavity 23 connects the hinge shaft 4 rotating on the hinge plate 101 to the sliding seat 102. The rotating cavity 23 and the hinge shaft 4 are coaxially arranged, and the inner diameter of the rotating cavity 23 is larger than the outer diameter of the hinge shaft 4. The extension length of the rotating cavity 23 is larger than the extension length of the slide groove 21. A rubber sleeve 5 is fixedly fitted on the part of the hinge shaft 4 opposite to the rotating cavity 23. The end of the rubber sleeve 5 away from the hinge seat 20 is a cone shape that gradually decreases in the direction away from the hinge seat 20, so that the side of the rubber sleeve 5 facing the hinge seat 20 forms an inclined surface 15 that is inclined relative to the moving direction of the sliding seat 102.
[0046] Reference Figure 4 and Figure 5 When the sliding seat 102 is in the initial position, it is located at the end of the rubber sleeve 5 away from the hinge seat 20. At this time, the sliding seat 102 does not interfere with the rubber sleeve 5. Then, the sliding seat 102 is moved closer to the hinge seat 20 so that the sliding seat 102 gradually interferes with the inclined surface 15 of the rubber sleeve 5 and squeezes the rubber sleeve 5. The frictional resistance between the rubber sleeve 5 and the sliding seat 102 restricts the rotation of the rubber sleeve 5 and the hinge shaft 4, thereby positioning the two separate hinge plates 101 relative to each other.
[0047] Reference Figure 2 In order to prevent the telescopic support rods 3 from interfering with each other, the distance between the two sliding seats 102 on each hinge plate 101 gradually increases in the direction away from the first fixed seat 103, so that the telescopic support rods 3 are misaligned with each other.
[0048] Reference Figure 2The second connecting component 2 includes a mounting base 201, a movable base 202, a second fixed base 203, and a positioning plate 204. The positioning plate 204 is square, and the mounting base 201 is square. The mounting base 201 is integrally formed on one side of the positioning plate 204, and the longitudinal cross-sectional dimension of the mounting base 201 is smaller than that of the positioning plate 204. The length extension direction of the mounting base 201 is parallel to the length extension direction of the hinge plate 101. The positioning plate 204 is bolted to the side wall of the column for installation. The mounting base 201 has a movable cavity 8 along its own length direction. The movable cavity 8 passes through the side of the mounting base 201 away from the positioning plate 204, and none of the movable cavities 8 pass through the two ends of the mounting base 201 that are far apart from each other.
[0049] Reference Figure 2 and Figure 7 The second fixed seat 203 is fixed in the middle of the movable cavity 8 and corresponds to the first fixed seat 103. Multiple movable seats 202 are provided, each sliding within the movable cavity 8 and corresponding to a sliding seat 102. The second fixed seat 203 and the movable seats 202 are distributed along the length of the mounting base 201, with the second fixed seat 203 located in the middle of the multiple movable seats 202. Both the movable seat 202 and the second fixed seat 203 are used to hinge the end of the sliding sleeve 31 away from the screw 32. Both the movable seat 202 and the second fixed seat 203 have portions extending from the mounting base 201 away from the positioning plate 204 for hinged connection with the end of the sliding sleeve 31. The sliding sleeve 31 corresponding to the screw 32 hinged to the first fixed seat 103 is hinged to the second fixed seat 203. The remaining telescopic support rods 3 are hinged between the corresponding sliding seats 102 and moving seats 202, and the distribution direction of each telescopic support rod 3 is parallel to the length direction of the hinge plate 101, and the vertical planes in which each telescopic support rod 3 is located are parallel to each other. Figure 3 The movable seat 202 has a second detachment block 24 at both the upper and lower ends. The mounting seat 201 has a second detachment groove at both the upper and lower ends of the movable cavity 8 for the second detachment block 24 to move along the length direction of the mounting seat 201, so as to restrict the movable seat 202 from detaching from the movable cavity 8 from the mounting seat 201.
[0050] Reference Figure 2 and Figure 5 The mounting base 201 has a drive assembly that cooperates with the movable base 202. The drive assembly can drive the movable base 202 to move along the length of the mounting base 201, so that the movable base 202 drives the corresponding sliding base 102 to move together through the hinged telescopic support rod 3, thereby enabling the sliding base 102 to move closer to or further away from the rubber sleeve 5.
[0051] During installation, first, each hinge plate 101 is locked to the bottom of the beam along its length, adapting the angle between the hinge plates 101 to the curvature of the beam to provide multiple support points. Then, the positioning plate 204 is locked to the column, with adaptive changes made to the distance between the screw 32 and the sliding sleeve 31, the angle of the screw 32 relative to the hinge plate 101, and the angle of the sliding sleeve 31 relative to the mounting base 201. Next, each locking ring 33 is threaded and moved until it abuts against the end of the sliding sleeve 31, so that the screw 32 and the sliding sleeve 31 jointly support the beam. Then, by driving the moving base 202 to move, the sliding base 102 moves along with it, gradually squeezing the rubber sleeve 5. This generates significant friction between the sliding base 102 and the rubber sleeve 5, limiting the rotation of the rubber sleeve 5 and the hinge shaft 4 relative to the sliding base 102, thereby locking the angle between the hinge plates 101.
[0052] Reference Figure 2 and Figure 8 The drive assembly includes a threaded rod 6 and an adjusting component 7. The threaded rod 6 is rotatably connected to the movable cavity 8 of the mounting base 201. The axis of the threaded rod 6 is parallel to the length direction of the mounting base 201. The threaded rod 6 is a bidirectional screw 32 with a forward rotation part 13 and a reverse rotation part 14. The forward rotation part 13 and the reverse rotation part 14 are arranged symmetrically on the threaded rod 6 with opposite threads. The second fixed base 203 is rotatably sleeved on the outer wall of the middle part of the threaded rod 6. The movable base 202 is threaded on the outer wall of the threaded rod 6. The two movable bases 202 corresponding to the two sliding bases 102 on the hinge plate 101 are respectively threaded on the forward rotation part 13 and the reverse rotation part 14, so that when the threaded rod 6 rotates, it drives the two movable bases 202 opposite to the hinge plate 101 to move towards each other or away from each other, thereby driving the two sliding bases 102 on the hinge plate 101 to press the corresponding rubber sleeve 5 in the direction of approaching each other, or to move away from each other and disengage from the rubber sleeve 5.
[0053] Reference Figure 8 and Figure 9 The adjusting component 7 cooperates with the threaded rod 6, i.e., the mounting base 201, to drive the threaded rod 6 to rotate relative to the mounting base 201 or to position the threaded rod 6 relative to the mounting base 201. Specifically, the adjusting component 7 includes a through rod 71, a locking head 72, and an adjusting ring 73. The through rod 71 is round and slides coaxially through the threaded rod 6. The two ends of the through rod 71 that are far apart from each other pass through the two ends of the mounting base 201 that are far apart from each other. A plurality of limit keys 11 are uniformly and integrally formed along the circumference of the through rod 71. Each limit key 11 extends along the length of the through rod 71. The inner wall of the threaded rod 6 has limit grooves 12 that correspond one-to-one with the limit keys 11, allowing the limit keys 11 to slide axially along the threaded rod 6. This guides the movement of the through rod 71 on the threaded rod 6, so that the through rod 71 and the threaded rod 6 can only move relative to each other in the threaded axial direction.
[0054] The locking head 72 is fixed to one end of the through rod 71. The locking head 72 is a disc-shaped object coaxial with the through rod 71 and has a positioning key 9 integrally formed on its outer circumference. Multiple positioning keys 9 are evenly distributed along the circumference of the locking head 72. The outer wall of the mounting base 201 near the end of the locking head 72 is provided with a positioning groove 10 for the positioning key 9 and the locking head 72 to be inserted together. By inserting the positioning key 9 into the positioning groove 10, the relative rotation between the locking head 72 and the mounting base 201 can be restricted.
[0055] The end of the through rod 71 furthest from the locking head 72 has an external thread. An adjusting ring 73 is threaded onto the end of the through rod 71 furthest from the locking head 72. When the locking head 72 and the positioning element are engaged in the positioning groove 10, the adjusting ring 73 is threadedly moved until it abuts against the end wall of the mounting base 201, thus preventing the locking head 72 from disengaging from the mounting base 201. This ensures that the through rod 71, the threaded rod 6, and the mounting base 201 are all relatively positioned. Moving the adjusting ring 73 threadedly away from the locking head 72 causes the locking head 72 to disengage from the positioning head. This rotation of the locking head 72, via the through rod 71, drives the threaded rod 6 to rotate. The locking head 72 can be rotated manually or connected to a motor.
[0056] Reference Figure 4 and Figure 6 Furthermore, in order to improve the stability of the telescopic support rod 3, a first support seat 16 corresponding to the sliding seat 102 is fixed at the bottom of the hinge plate 101. The first support seat 16 has a portion extending to the opposite side of the sliding groove 21, and the bottom wall of the sliding seat 102 is flush with the bottom wall of the hinge plate 101 and abuts against the upper surface of the first support seat 16 to enhance the stability of the sliding seat 102. A first rubber layer 17 is fixed on the side of the first support seat 16 facing the screw 32. The first rubber layer 17 has a first inclined surface 25 that gradually slopes towards the screw 32 from the direction near the middle of the hinge plate 101.
[0057] Reference Figure 2 and Figure 7 A second support seat 18 corresponding to the movable seat 202 is fixed on the side of the mounting base 201 away from the positioning plate 204. The second support seat 18 is located below the sliding sleeve 31 on the corresponding movable seat 202. The top of the second support seat 18 is opposite to the movable cavity 8. The movable seat 202 and the second support seat 18 abut against each other on the side of the movable cavity 8 to enhance the stability of the movable seat 202. A second rubber layer 19 is fixed on the top surface of the second support seat 18 facing the sliding sleeve 31. The second rubber layer 19 has a second inclined surface 26 that gradually extends upward along the direction close to the second fixed base 203.
[0058] Reference Figure 5 , Figure 6 and Figure 7When the sliding seat 102 is in its initial position and does not interfere with the rubber sleeve 5, the screw 32 does not interfere with the first rubber layer 17, and the sliding sleeve 31 does not interfere with the second rubber layer 19. When the sliding seat 102 gradually squeezes the rubber sleeve 5, it drives the screw 32 to gradually squeeze the first rubber layer 17 at the same time, and the sliding sleeve 31 to gradually squeeze the second rubber layer 19 at the same time. The frictional force generated between the screw 32 and the first rubber layer 17 and the frictional force generated between the sliding sleeve 31 and the second rubber layer 19 restricts the telescopic support rod 3 from rotating relative to the hinge plate 101 and the mounting seat 201, thereby improving the stability of the telescopic support rod 3. In addition, the first rubber layer 17 and the second rubber layer 19 can absorb pressure and play a buffering role, so that the telescopic support rod 3 can better cope with changes in the external environment.
[0059] Furthermore, multiple grooves 27 are provided on the side of the sliding seat 102 facing the rubber sleeve 5, the circumference of the hinge end of the screw 32 along the rotation direction, and the circumference of the hinge end of the sliding sleeve 31 along the rotation direction. This allows the rubber sleeve 5 to be squeezed into the groove 27 of the sliding seat 102 when the sliding seat 102 and the rubber sleeve 5 are pressed together, the first rubber layer 17 to be squeezed into the groove 27 of the screw 32, and the second rubber layer 19 to be squeezed into the groove 27 of the sliding sleeve 31. This further prevents relative rotation between the sliding seat 102 and the rubber sleeve 5, between the screw 32 and the first rubber layer 17, and between the sliding sleeve 31 and the second rubber layer 19.
[0060] The implementation principle of the reinforced steel structure at the steel structure connection of this application embodiment is as follows: each hinge plate 101 is locked to the bottom of the beam by welding or bolting, and the positioning plate 204 is locked to the side of the column by welding or bolting. Then, the locking ring 33 is threaded and moved to abut against the end of the sliding sleeve 31. After that, by rotating the locking head 72, the through rod 71 and the threaded rod 6 are rotated, so that the moving seats 202 at both ends of the threaded rod 6 move towards each other, driving the telescopic support rod 3 and the sliding seat 102 to move together, so that the sliding seat 102 gradually squeezes the rubber sleeve 5, the screw 32 gradually squeezes the first rubber layer 17 and the sliding sleeve 31 gradually squeezes the second rubber layer 19.
