Description

Technical Field

[0001] This invention relates to the field of truss support technology, specifically a truss web member connection support structure for steel structures. Background Technology

[0002] In existing steel truss construction systems, the web structure bears a heavy load. The vertical web members of the steel roof truss are important components connecting the roof purlins and the foundation. They bear the vertical components of roof loads, wind loads, and seismic loads, and play a role in enhancing structural stability. They can generally be divided into two main types: tension members and compression members, and are important components for bearing vertical loads.

[0003] Chinese Patent Publication No. CN219261831U discloses a steel truss web member structure. In this solution, the support rod is opened to push the universal joint to move to the designated position, and the connecting rod at the corresponding position is pulled to move the first connecting seat and the second connecting seat to the designated position. Then, the bolts are tightened to adjust the size and specifications of the steel truss web member structure, thereby expanding its applicability and enhancing its practicality.

[0004] In this scheme, the connecting rod is moved to a designated position by the first connecting seat and the second connecting seat and connected to the connecting rod of other adjacent web members, which can meet the connection requirements of different sizes. However, this adjustment method is unidirectional. If one direction is adjusted to meet the connection requirements of that direction, then the other direction cannot be adjusted, that is, it cannot meet the connection requirements of multiple directions at the same time.

A horizontal plate is disposed on the side of the round rod away from the movable plate. A horizontal groove is formed in the center of the horizontal plate. The round rod is movably connected to the horizontal groove. The end of the horizontal plate away from the round rod is fixedly connected to the middle of the movable rod.

[0009] As a further aspect of the present invention: a slot is provided in the center of the movable plate, a rotating rod is provided in the slot, a cam is fixedly provided at one end of the rotating rod, the cam is located between the two vertical rods and the side of the cam can movably abut against the vertical rod, and the end of the rotating rod away from the cam movably passes through the movable plate and the cylinder and the end is rotatably connected to the circular plate.

[0010] As a further aspect of the present invention: a plurality of limiting holes are provided laterally on one side of the fixed frame, and a limiting ball is provided on the side of the moving rod near the limiting hole, and the limiting ball is movably engaged with the limiting hole.

[0011] As a further embodiment of the present invention: a ring is fixedly disposed inside the limiting hole, a push rod is movably disposed through the center of the ring, and a first spring is fixedly disposed between the push rod and the ring.

[0012] As a further aspect of the present invention: a positioning frame is provided on one side of the circular plate located on the fixed frame, a sliding plate is movably arranged inside the positioning frame, and a plurality of push rods are provided on the side of the sliding plate near the fixed frame, the push rods being movably abutting against one side of the top rod.

[0013] As a further embodiment of the present invention: a groove is provided in the center of the sliding plate, an inclined block is movably arranged in the groove, a lifting rod is rotatably connected above the inclined block, a through hole is provided on one side of the positioning frame, the lifting rod movably passes through the through hole, a limit plate is fixedly provided on the side of the inclined block away from the lifting rod, the limit plate movably passes through the other side of the positioning frame, and a second spring is fixedly provided between the top of the inclined block and the positioning frame.

[0014] As a further aspect of the present invention: a portion of the through hole near the outlet is designed in a threaded shape, and a portion of the outer side of the lifting rod is also designed in a threaded shape and the two are connected by threaded fit.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The upward movement of the rotating ring drives the limiting plate to move upward. The upward movement of the limiting plate, through the action of the inclined block, inclined groove, sliding plate and push rod, causes the top rod to "block" one end of the limiting hole, so that the limiting ball will not be stuck with the limiting hole, which facilitates the movement of the moving rod. The rise of the inclined block will also drive the lifting rod to pass through the through hole. With the help of the curved groove and the limiting rod, the lifting rod rotates during the upward movement, causing the lifting rod and the through hole to be threadedly engaged, ensuring the stability of the lifting rod and the inclined block. At the same time, the upward movement of the rotating ring drives the locking block to engage with the locking groove. At this time, the rotation of the rotating ring will drive the cylinder to rotate, which can drive the moving rod to move and change the position of the connecting plate, which can meet different connection requirements. In addition, the rotation of the cam can further drive the moving rod to make fine adjustments to the lateral distance. Attached Figure Description

[0029] Please see Figures 1-11 In this embodiment of the invention, a truss web member connection support structure for steel structures includes a base 1, on which a vertical post 2 is fixedly mounted. A circular plate 3 is fixedly mounted at the end of the vertical post 2 away from the base 1. A cylinder 4 is rotatably mounted on the side of the circular plate 3 away from the vertical post 2. A connecting component 5 for connecting with an adjacent web member structure is provided above the cylinder 4. An adjusting component 6 for adjusting the position of the connecting component 5 is provided on the side of the cylinder 4 away from the circular plate 3. The adjusting component 6 is kinetically connected to the connecting component 5. Web member structures are used in various fields such as foundation pit engineering and building construction. The base 1 can have multiple mounting holes, which can be screwed together to connect with... The ground support structure is connected, with uprights 2 providing support. The two ends of the connecting component 5 can be connected to the connecting components 5 of the adjacent web structure, thus connecting multiple web structures together to build a frame. However, when connecting components 5 are connected to other structures on both sides, they cannot always be perfectly aligned, as the dimensions may not fit perfectly. There may be issues where the distance on one side is insufficient for connection. Therefore, it is necessary to adjust the position of the connecting structure within the connecting component 5 to meet the connection requirements of different distances. By adjusting component 6, the distance the connecting structure within the connecting component 5 can be moved to one side, allowing it to adapt to different length installation requirements. Circular plates 3 and columns 4 provide support.

[0030] See Figures 2-3As shown, in this embodiment, preferably, the connecting assembly 5 includes fixed rods 51 axially symmetrically arranged on both sides of the cylinder 4. One end of the fixed rod 51 is fixedly connected to the circular plate 3, and a fixed frame 52 is fixedly arranged at the end of the fixed rod 51 away from the circular plate 3. A movable rod 53 is movably coupled between the two fixed frames 52. Both ends of the movable rod 53 are fixedly provided with connecting plates 54. When the position of the connecting plates 54 on both sides of the movable rod 53 does not need to be adjusted, it can be connected to the components on the adjacent sides through the connecting plates 54. When the length of one side needs to be adjusted, the movable rod 53 is moved, and the movable rod 53 drives the connecting plate 54 to move to the left or right, which can increase or decrease the distance between the connecting plate 54 on one side and the adjacent component, meeting the connection requirements of different lengths. The fixed frame 52 provides support for the movement of the movable rod 53. In this step, the position of the connecting plate 54 can be adjusted to meet the connection requirements of different lengths. At the same time, the lengths on both sides are changed, that is, the positions of the connecting plates 54 on both sides are changed. In a practical application scenario, one of the connecting plates 54 is not far enough from the adjacent connecting component, and the length of the other connecting plate 54 exceeds the distance between it and the adjacent connecting component. The upright 2 and the base 1 have been fixed to the ground. The conventional approach would be to remove the fixing of the base 1 from the ground and then move the base 1 so that the connecting plates 54 on both sides can be connected to their adjacent connecting components. However, removing the base 1 will increase the workload. Adjusting the position of the movable rod 53 can just meet the change of the position of the two connecting plates 54, thereby meeting the requirements.

[0031] See Figures 2-5As shown, in this embodiment, preferably, the adjusting component 6 includes a fixed plate 61, which is fixedly connected to the upper surface of the cylinder 4. A movable plate 62 is slidably disposed within the fixed plate 61. Vertical rods 63 are axially symmetrically fixedly disposed on the upper surface of the movable plate 62. One of the vertical rods 63 has a groove 64 at its center. A round rod 65 is movably disposed within the groove 64. A horizontal plate 66 is disposed on the side of the round rod 65 away from the movable plate 62. A horizontal groove 67 is formed in the center of the horizontal plate 66. The round rod 65 is movably connected to the horizontal groove 67. The end of the horizontal plate 66 away from the round rod 65 is fixedly connected to the middle of the movable rod 53. Rotating the cylinder 4, the rotation of the cylinder 4 is fixed. When plate 61 rotates, since the horizontal plate 66 and the moving rod 53 are fixedly connected, and a round rod 65 is provided in the groove 64 of the vertical rod 63, and the round rod 65 is connected to the horizontal plate 66, the clockwise rotation of the cylinder 4 and the fixed plate 61 will cause the moving plate 62 to slide within the fixed plate 61, and the moving rod 53 will move to the right, changing the position of the connecting plates 54 on both sides. The round rod 65 moves with the movement of the moving plate 62, and the other end of the round rod 65 moves within the horizontal groove 67. Similarly, when the cylinder 4 and the fixed plate 61 rotate counterclockwise, the moving plate 62 will slide within the fixed plate 61, and the moving rod 53 will move to the left. By adjusting the direction of movement of the moving rod 53 through the above steps, different installation requirements can be met.

[0032] See Figures 4-5As shown, in this embodiment, preferably, the movable plate 62 has a slot 621 at its center, and a rotating rod 7 is disposed within the slot 621. A cam 8 is fixedly disposed at one end of the rotating rod 7. The cam 8 is located between the two vertical rods 63, and its side can movably abut against the vertical rod 63. The end of the rotating rod 7 away from the cam 8 movably passes through the movable plate 62 and the cylinder 4, and its end is rotatably connected to the circular plate 3. When both connecting plates 54 can be smoothly connected to adjacent connecting components, there is no need to adjust the position of the connecting plates 54. Rotating the rotating rod 7 within the slot 621 causes the cam 8 to rotate, and the protruding part of the cam 8 will successively abut against the two vertical rods 63, causing the movable plate 62 to move within the fixed plate 61. At this time, the other end of the circular rod 65 also moves within the transverse groove 67. Since the moving rod 53 and the horizontal plate 66 are aligned vertically at this time, the movement of the round rod 65 will not cause the moving rod 53 to move horizontally left or right, and the position of the connecting plate 54 will not change. When it is necessary to adjust the position of the connecting plate 54, rotate the cylinder 4 clockwise or counterclockwise until the moving plate 62 and the fixed plate 61 are set horizontally. At this time, the moving rod 53 moves the longest distance to the right or left. If the ideal effect is still not achieved at this time, that is, there is still a certain distance between the side with the longer movement distance and the adjacent connecting component, and the length of the connecting plate 54 on the other side still exceeds the length between the connecting plate 54 on that side and the adjacent connecting component, then rotate the cam 8. The rotation of the cam 8 can drive the moving rod 53 to move a small distance again, so that the position of the moving rod 53 and the connecting plate 54 is finely adjusted again, which can further meet the connection requirements.

[0033] See Figure 1 , Figure 3 and Figure 6 As shown, in this embodiment, preferably, a plurality of limiting holes 521 are laterally opened on one side of the fixed frame 52, and a limiting ball 9 is provided on the side of the moving rod 53 near the limiting hole 521. The limiting ball 9 is movably engaged with the limiting hole 521. When the moving rod 53 moves within the fixed frame 52, thereby changing the position of the connecting plate 54, after the position is determined, the connecting plate 54 needs to be fixedly connected with the adjacent connecting component. At this time, it is necessary to ensure the stability of the moving rod 53, and it should not move left or right or shake, which would be detrimental to the fixed connection of the connecting plate 54. Therefore, after the position of the connecting plate 54 is determined, the limiting ball 9 is engaged with the limiting hole 521. In this way, under the limiting action of the limiting ball 9, the moving rod 53 will not move within the fixed frame 52.

[0034] See Figure 7As shown, in this embodiment, preferably, a ring 10 is fixedly disposed inside the limiting hole 521, and a push rod 11 is movably disposed through the center of the ring 10. A first spring 12 is fixedly disposed between the push rod 11 and the ring 10. When the position of the connecting plate 54 needs to be changed, the push rod 11 is pressed inward along the limiting hole 521. The push rod 11 moves inward and pushes the limiting ball 9 to release the locking relationship with the limiting hole 521. The limiting ball 9 is made of an elastic material. During this process, the first spring 12 is in a compressed state. After the limiting ball 9 is released from the limiting hole 521, the force applied to the push rod 11 is removed. Under the action of the first spring 12, the push rod 11 is driven to return to its initial state. The ring 10 provides support for the first spring 12.

[0035] See Figure 8 As shown, in this embodiment, preferably, the circular plate 3 is provided with a positioning frame 13 on one side of the fixed frame 52. A sliding plate 14 is movably arranged inside the positioning frame 13. Multiple push rods 15 are arranged on the side of the sliding plate 14 near the fixed frame 52. The push rods 15 movably abut against one side of the top rod 11. When it is necessary to adjust the position of the moving rod 53, the movement of the moving rod 53 will drive the limiting ball 9 to move. At this time, the limiting hole 521 and the side of the limiting ball 9 are in a vacuum state. The limiting ball 9 will directly engage with the first limiting hole 521. Only after the engagement between the limiting ball 9 and the first limiting hole 521 is released can the moving rod 53 continue to move. During the movement, the limiting ball 9 will also successively engage with multiple subsequent limiting holes 521. This makes it inconvenient to adjust the position of the moving rod 53. To move the rod 53, the sliding plate 14 is moved. The movement of the sliding plate 14 within the positioning frame 13 drives the push rod 15 to move, thereby pushing the top rod 11 inward along the limiting hole 521 until one end of the top rod 11 is flush with the side of the limiting hole 521 closest to the moving rod 53. The top rod 11 "blocks" one side of the limiting hole 521, so the limiting ball 9 will not get stuck with the limiting hole 521 during the movement of the rod 53. After the position of the moving rod 53 is adjusted, the sliding plate 14 is moved in the opposite direction. The sliding plate 14 drives the push rod 15 to move in the opposite direction. Since the force of the push rod 15 is lost, the top rod 11 returns to its original position under the action of the first spring 12. The limiting ball 9 can get stuck with the limiting hole 521, ensuring the stability of the moving rod 53.

[0036] See Figure 8As shown, in this embodiment, preferably, the sliding plate 14 has a groove 141 at its center, and an inclined block 16 is movably disposed within the groove 141. A lifting rod 17 is rotatably connected above the inclined block 16. A through hole 131 is provided on one side of the positioning frame 13, and the lifting rod 17 movably passes through the through hole 131. A limiting plate 18 is fixedly disposed on the side of the inclined block 16 away from the lifting rod 17, and the limiting plate 18 movably passes through the other side of the positioning frame 13. A second spring 19 is fixedly disposed between the top of the inclined block 16 and the positioning frame 13. Moving the limiting plate 18 upward causes the inclined block 16 to move upward, which in turn moves the inclined block 16 upward. This movement is facilitated by the inclined block 16 and the groove 141. Due to their positional relationship, the upward movement of the inclined block 16 causes the sliding plate 14 to move closer to the fixed frame 52, which in turn causes the push rod 15 to move the top rod 11 inward along the limiting hole 521, preventing the limiting ball 9 from getting stuck with each limiting hole 521. The upward movement of the inclined block 16 causes the lifting rod 17 to move upward through the through hole 131. During this process, the second spring 19 is in a compressed state. After the position of the moving rod 53 is determined, the upward force applied to the limiting plate 18 is removed. Under the action of the second spring 19, the inclined block 16 moves downward, thereby causing the sliding plate 14 and the push rod 15 to move away from the fixed frame 52. As a result, the limiting ball 9 can get stuck with the limiting hole 521.

[0037] See Figures 8-10 As shown, in this embodiment, preferably, a portion of the through hole 131 near the outlet is threaded, and a portion of the outer side of the lifting rod 17 is also threaded, with the two threadedly connected. A curved groove 171 is formed below the threaded portion of the lifting rod 17, and a limiting rod 20 is slidably fitted within the curved groove 171. The limiting rod 20 is fixedly connected to the inner wall of the through hole 131. As the limiting plate 18 moves upward, the lifting rod 17 passes through the through hole 131. Because the limiting rod 20 is provided within the through hole 131 and the curved groove 171 is formed on the surface of the lifting rod 17, the lifting rod 17... 7. During the upward movement, the lifting rod 17 rotates synchronously, causing the threaded part of the lifting rod 17 to engage with the threaded part in the through hole 131, ensuring the stability of the lifting rod 17. The inclined block 16 will not move downward, and the push rod 15 will always be pressed against one side of the top rod 11, ensuring the smooth adjustment of the position of the moving rod 53. After the position of the moving rod 53 is adjusted, the lifting rod 17 can be rotated in the opposite direction, which can release the engagement between the threads and at the same time move downward under the action of the limit rod 20 and the curved groove 171, causing the push rod 15 to release the pushing action on the top rod 11, so that the limit ball 9 engages with the limit hole 521.

[0038] See Figures 4-5 and Figure 11As shown, in this embodiment, preferably, an annular groove 41 is formed on the outer side of the cylinder 4, and a rotating ring 21 is movably disposed within the annular groove 41. A third spring 22 is fixedly disposed between the bottom of the rotating ring 21 and the cylinder 4. The cylinder 4 has multiple slots 42 formed within the annular groove 41, and multiple locking blocks 23 are fixedly disposed on the rotating ring 21 at positions relative to the slots 42. The locking blocks 23 are movably engaged with the slots 42, and the upper surface of the rotating ring 21 is movably abutting against the lower surface of the limiting plate 18. The rotating ring 21 moves upward along the annular groove 41. The rotating ring 21 moves upward, causing the locking block 23 to engage with the locking groove 42. The third spring is in a stretched state. At this time, the rotation of the rotating ring 21 can cause the cylinder 4 to rotate, which can adjust the position of the connecting plate 54. At the same time, the upward movement of the rotating ring 21 will also cause the limiting plate 18 to move upward, thus facilitating the movement of the moving rod 53 within the fixed frame 52. Because at this time, the limiting ball 9 will not engage with the limiting hole 521. After the position of the connecting plate 54 is adjusted, the rotating ring 21 moves downward along the annular groove 41 under the action of the third spring 22, causing the locking block 23 to disengage from the locking groove 42.

[0039] The working principle of this invention is as follows: The rotating ring 21 moves upward along the annular groove 41. This upward movement of the rotating ring 21 causes the locking block 23 to engage with the locking groove 42, resulting in a stretched state. At this time, the rotation of the rotating ring 21 can cause the cylinder 4 to rotate. The rotating cylinder 4 causes the fixed plate 61 to rotate. Since the horizontal plate 66 and the moving rod 53 are fixedly connected, and a round rod 65 is provided in the groove 64 of the vertical rod 63, connected to the horizontal plate 66, the clockwise rotation of the cylinder 4 and the fixed plate 61 will cause the moving plate 62 to slide within the fixed plate 61. Simultaneously, the moving rod 53 will move to the right, changing the position of the connecting plates 54 on both sides. The round rod 65 moves along with the moving plate 62. The other end of the round rod 65 is in the horizontal groove 67. Similarly, when the cylinder 4 and the fixed plate 61 rotate counterclockwise, the moving plate 62 will slide within the fixed plate 61, and the moving rod 53 will move to the left. The connecting plates 54 on both sides of the moving rod 53 can connect with the adjacent connecting components. When both connecting plates 54 can connect smoothly with the adjacent connecting components, there is no need to adjust the position of the connecting plates 54. Rotating the rotating rod 7 will cause the cam 8 to rotate within the slot 621. The protruding part of the cam 8 will successively abut against the two vertical rods 63, causing the moving plate 62 to move within the fixed plate 61. At this time, the other end of the round rod 65 also moves within the transverse slot 67. Since the moving rod 53 and the transverse plate 66 are aligned vertically at this time, the round rod 65... The movement of rod 65 will not cause the moving rod 53 to move laterally left or right, and the position of the connecting plate 54 will not change. When it is necessary to adjust the position of the connecting plate 54, rotate cylinder 4 clockwise or counterclockwise until the moving plate 62 and the fixed plate 61 are horizontally positioned. At this time, the moving rod 53 will move the longest distance to the right or left. If the desired effect is still not achieved at this time, that is, there is still a certain distance between the side with the longer movement distance and the adjacent connecting component, and the length of the connecting plate 54 on the other side still exceeds the length between the connecting plate 54 on that side and the adjacent connecting component, then rotate cam 8. The rotation of cam 8 can drive the moving rod 53 to move a small distance again, so that the positions of the moving rod 53 and the connecting plate 54 are adjusted again. Fine-tuning is performed to further meet connection requirements. Simultaneously, the upward movement of the rotating ring 21 also drives the limiting plate 18 upward. The upward movement of the limiting plate 18 drives the inclined block 16 upward. Utilizing the positional relationship between the inclined block 16 and the inclined groove 141, the upward movement of the inclined block 16 drives the sliding plate 14 to move closer to the fixed frame 52, causing the push rod 15 to drive the top rod 11 to move inward along the limiting hole 521. This prevents the limiting ball 9 from jamming with each limiting hole 521, facilitating the movement of the moving rod 53 within the fixed frame 52. The lifting rod 17, as the limiting plate 18 moves upward, passes through the through hole 131. Since the through hole 131 is equipped with a limiting rod 20 and the surface of the lifting rod 17 has a curved groove 171, this process is necessary.Therefore, during the upward movement of the lifting rod 17, it rotates synchronously, causing the threaded portion of the lifting rod 17 to engage with the threaded portion inside the through hole 131. This ensures the stability of the lifting rod 17, and the inclined block 16 will not move downward. The push rod 15 also remains against one side of the top rod 11, ensuring the smooth adjustment of the position of the moving rod 53. Once the position of the moving rod 53 is adjusted, the lifting rod 17 can be rotated in the opposite direction. This releases the engagement between the threads and, simultaneously, under the action of the limiting rod 20 and the curved groove 171, moves downward, causing the push rod 15 to release its pushing effect on the top rod 11, allowing the limiting ball 9 to engage with the limiting hole 521.
