Description

Technical Field

[0001] This invention belongs to the field of suspension rod reverse support technology, and specifically relates to a suspension rod reverse support structure. Background Technology

[0002] Clause 6.1.11 of the "Code for Acceptance of Construction Quality of Building Decoration and Renovation Engineering" (GB50210-2001) states that "when the length of the hanger rod is greater than 1.5m, a counter-bracing should be installed." Clause 4.2.3 of the "Technical Specification for Ceiling Engineering of Public Buildings" (JGJ345-2014) states that "when the length of the hanger rod is greater than 1500mm, a counter-bracing should be installed. The spacing between counter-bracing should not exceed 3600mm, and the distance from the wall should not exceed 1800mm. Counter-bracing should be arranged adjacent to each other. When the length of the hanger rod is greater than 2500mm, a steel structure transfer layer should be installed." The purpose of installing counter-bracing is to resist the negative wind pressure on the surface layer. If the hanger rods are not reinforced, quality defects such as panel concavity and hanger rod bending will occur over time.

[0003] In existing technologies, eye bolts are typically installed on vertical and horizontal hangers to connect them. However, in actual use, to achieve the matching of the connection angle and position of the vertical and horizontal hangers, it is necessary to manually and continuously tighten the eye bolts to adjust their positions on the vertical and horizontal hangers. This results in low installation efficiency and great inconvenience for installing the hanger counter-support structure. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a rod counter-support structure to solve the problem that in the prior art, it is necessary to manually and continuously tighten the lifting eye bolts to adjust the position of the lifting eye bolts on the vertical and horizontal rods in order to reach the specified connection position, which leads to the low installation efficiency of the rod counter-support structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention discloses a rod counter-support structure, comprising a vertical rod and an inclined rod. The middle portions of the vertical and inclined rods are respectively provided with several rows of circumferentially distributed first and second slots. Sliding engagement mechanisms are provided on the outer sides of both the vertical and inclined rods. The sliding engagement mechanisms are configured identically on both the vertical and inclined rods. The sliding engagement mechanism on the vertical rod includes an inner sliding ring, which is sleeved on the vertical rod and has annular blocks at both ends. An outer rotating ring is provided between the annular blocks. The inner sliding ring has several sets of sliding grooves matching the first slots. A slider is provided within each sliding groove. A spring is provided at one end of the slider facing the outer rotating ring, with one point of the spring fixed to the slider and the other end abutting against the inner wall of the outer rotating ring. A first connecting member and a second connecting member are respectively provided on the surface of the outer rotating ring in both the vertical and inclined rods. The first and second connecting members are used to connect the inclined rod to the vertical rod.

[0007] Furthermore, limiting plates are provided on the outer sides of the two opposite sides of the slider, and the limiting plates are fixed to the outer side of the inner slip ring.

[0008] Furthermore, the ends of the vertical and inclined booms are provided with guide round heads.

[0009] Furthermore, the first connecting member includes a first connecting post, one end of which is fixed to the outer surface of the outer rotating ring on the vertical boom, and the other end of which is provided with an annular locking cavity. One end of the annular locking cavity is fixed to the first connecting post, and the surface of the annular locking cavity near the other end is provided with a plurality of circular through holes around its circumference. A ball is provided in the circular through hole, and an annular limiting cavity is provided on the outer side of the ball. An avoidance groove is provided on the inner side of the annular limiting cavity near the ball, and a sliding plate is provided at the other end of the annular limiting cavity. The sliding plate is slidably connected to the first connecting post, and a clamping spring is provided on the sliding plate. The clamping spring is sleeved on the first connecting post, and one end of the clamping spring is fixed to the sliding plate. The second connecting member includes a second connecting post, one end of which is fixed to the surface of the outer rotating ring on the inclined boom, and the other end of which is provided with an annular retaining plate. The outer diameter of the annular retaining plate matches the inner diameter of the annular locking cavity.

[0010] Furthermore, the annular plate has a supporting column in the middle, the first connecting column is a hollow column, and the outer diameter of the supporting column matches the inner diameter of the first connecting column.

[0011] Furthermore, a limiting post is provided on the surface of the sliding plate facing the vertical pole. One end of the limiting post is fixed to the sliding plate, and the distance between the other end of the limiting post and the outer rotating ring is equal to the distance from the center of the ball to the outer edge of the clearance groove.

[0012] Furthermore, both the vertical and inclined booms are hollow booms, and the first and second slots are respectively connected to the interior of the vertical and inclined booms.

[0013] The beneficial effects of this invention are as follows:

[0014] This technical solution allows for adjustment of the inner slip ring's position on the vertical hanger by sliding the inner slip ring on the vertical hanger. Once the position is adjusted, simply rotate the inner slip ring to position the slider at the first slot. Under the action of the spring reset, the slider can be pushed into the first slot, thus achieving engagement and limiting the position of the inner slip ring on the vertical hanger. This enables rapid position adjustment and improves installation efficiency.

Detailed Implementation

[0025] like Figures 1-6 As shown, the present invention discloses a rod counter-support structure, comprising a vertical rod 1 and an inclined rod 2. The middle portions of the vertical rod 1 and the inclined rod 2 are respectively provided with several rows of circumferentially distributed first slots 3 and second slots 4. In this specific embodiment, the number of rows of first slots 3 and second slots 4 is preferably three. The specific number of first slots 3 and second slots 4 can be determined according to the length of the vertical rod 1 and the inclined rod 2. Sliding engagement mechanisms are provided on the outer sides of both the vertical rod 1 and the inclined rod 2. The sliding engagement mechanisms are arranged in the same way on both the vertical rod 1 and the inclined rod 2. The sliding engagement mechanism provided on the vertical rod 1 includes an inner slip ring 5. The inner slip ring 5 is set with... An annular stop block 6 is provided on the surface of the vertical rod 1 with both ends facing outward. An outer rotating ring 10 is provided between the annular stop blocks 6. The outer rotating ring 10 can rotate around the inner sliding ring 5. The inner sliding ring 5 is provided with several sets of sliding grooves 7 that match the first slot 3. A slider 8 is provided in the sliding groove 7. A spring 9 is provided at one end of the slider 8 facing the outer rotating ring 10. One point of the spring 9 is fixed to the slider 8, and the other end of the spring 9 abuts against the inner wall of the outer rotating ring 10. A first connecting member and a second connecting member are respectively provided on the surface of the outer rotating ring 10 in the vertical rod 1 and the inclined rod 2. The first connecting member and the second connecting member are used to connect the inclined rod 2 to the vertical rod 1.

[0026] The principle behind the rapid installation of this technical solution is as follows:

[0027] The sliding locking mechanism is sleeved onto the vertical rod 1 from the end. During position adjustment, the end of the slider 8 is located on the surface of the vertical rod 1 between adjacent first slots 3. Under the pressure, the slider 8 will compress the spring 9, causing the spring 9 to contract, thereby making the end of the slider 8 flush with the slide groove 7. At this time, the inner sliding ring 5 can move up and down on the vertical rod 1, while the outer rotating ring 10 can rotate relative to the inner sliding ring 5. This allows adjustment of the height and rotation angle of the first connecting member relative to the vertical rod 1. When the position is adjusted... Once in position, simply rotate the inner slip ring 5 to position the slider 8 at the first slot. Under the reset action of the spring 9, the slider 8 can be pushed into the first slot 3, thus achieving engagement. This limits the position of the inner slip ring 5 on the vertical rod 1. Similarly, by adjusting the position of the sliding engagement mechanism on the inclined rod 2, the first and second connecting parts can be aligned, thereby connecting the vertical rod 1 and the inclined rod 2. After the connection is completed, the inclined rod 2 can provide counter-support for the vertical rod 1.

[0028] In one feasible embodiment, limiting plates are provided on the outer sides of the opposite sides of the slider 8. The limiting plates are fixed to the outer side of the inner sliding ring 5. The limiting plates can limit the lateral displacement of the slider 8, thus preventing the slider 8 from falling off due to the bending of the spring 9 when the outer rotating ring 10 rotates.

[0029] In one feasible embodiment, the ends of the vertical rod 1 and the inclined rod 2 are provided with guide round heads. The provision of guide round heads can apply an oblique force to the slider 8, thereby guiding the movement of the slider 8 in the slide groove 7, which facilitates the initial installation of the inner slip ring 5 on the vertical rod 1. If not provided, the slider 8 will interfere with the end of the vertical rod 1 because it protrudes from the inner wall of the inner slip ring 5.

[0030] In one feasible embodiment, the first connector includes a first connecting post 11. One end of the first connecting post 11 is fixed to the outer surface of the outer rotating ring 10 provided on the vertical rod 1. The other end of the first connecting post 11 is provided with an annular locking cavity 12, which can be understood as a hollow column. One end of the annular locking cavity 12 is fixed to the first connecting post 11. A plurality of circular through holes 13 are provided circumferentially on the surface of the annular locking cavity 12 near the other end. A ball bearing 14 is provided in the circular through hole 13. The diameter of the ball bearing 14 is larger than the diameter of the circular through hole 13. An annular limiting cavity 15 is provided on the outer side of the ball bearing 14. The annular limiting cavity 15 is also a hollow column. An abutment groove 17 is provided on the inner side of the end of the 15 near the ball 14. The abutment groove 17 is an annular groove. The other end of the annular limiting cavity 15 is provided with a sliding plate 16. The sliding plate 16 is slidably connected to the first connecting post 11. A retaining spring 18 is provided on the sliding plate 16. The retaining spring 18 is sleeved on the first connecting post 11, and one end of the retaining spring 18 is fixed on the sliding plate 16. The second connecting member includes a second connecting post 20. One end of the second connecting post 20 is fixed to the surface of the outer rotating ring 10 provided on the inclined rod 2. The other end of the second connecting post 20 is provided with an annular locking plate 19. The outer diameter of the annular locking plate 19 matches the inner diameter of the annular locking cavity 12.

[0031] The connection principle between the first connector and the second connector is as follows:

[0032] First, slide the annular limiting cavity 15 to compress the clamping spring 18, so that the clearance groove 17 is above the ball 14. Then, slide the annular slot into the annular locking cavity 12. During the sliding process, the annular locking plate 19 squeezes the ball 14, causing the ball 14 to move upward in the clearance groove 17, so as not to obstruct the movement of the annular locking plate 19. After the annular locking plate 19 moves to the position, release the annular limiter to reset the annular limiter. During the reset process, its inner wall contacts the ball 14, pressing the ball 14 into the circular through groove. At this time, the part of the ball 14 is located in the annular locking cavity 12, which can block the outward movement of the annular locking plate 19, thereby realizing the connection.

[0033] In one feasible embodiment, a bearing column 22 is provided in the middle of the annular clamping plate 19, and the first connecting column 11 is a hollow column. The outer diameter of the bearing column 22 matches the inner diameter of the first connecting column 11. With this arrangement, when the annular clamping plate 19 is located at a designated position in the annular locking cavity 12, the bearing column 22 slides into the interior of the first connecting column 11. Thus, when the inclined shaft hoist is subjected to force, the torque can be transmitted through the compression between the bearing column 22 and the first connecting column 11, rather than simply through the annular clamping plate 19, thereby improving the force-bearing effect.

[0034] In one feasible embodiment, a limiting post 21 is provided on the surface of the sliding plate 16 facing the vertical pole. One end of the limiting post 21 is fixed to the sliding plate 16, and the distance between the other end of the limiting post 21 and the outer rotating ring 10 is equal to the distance from the center of the ball 14 to the outer edge of the relief groove 17. That is, when the sliding annular limiting cavity 15 is sliding, when the limiting post 21 abuts against the outer rotating ring 10, the center of the ball 14 is just located at the edge of the relief groove 17. That is, the ball 14 is located in the relief groove 17 and can move upward, but its center is still inside the relief groove 17, that is, it will not fall out.

[0035] In one feasible embodiment, both the vertical rod 1 and the inclined rod 2 are hollow rods. The first slot 3 and the second slot 4 are respectively connected to the interior of the vertical rod 1 and the inclined rod 2. The hollow rods can reduce weight, and the slider 8 can slide inside the hollow rods, resulting in better locking and clamping effects.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
