Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to an installation device and method for suspending components under steel beams. Background Technology

[0002] A steel beam under-bracing component is a structural element used to enhance the stability and load-bearing capacity of steel beams. It is typically installed at the bottom of the steel beam and, through its connection to the beam, distributes the load, reducing deformation and cracking. The design and installation of this component contributes to improving the overall stability and seismic performance of the structure, playing a crucial role, especially during natural disasters such as earthquakes. Furthermore, it can adapt to different installation requirements, allowing for flexible installation and use by adjusting its position and angle.

[0003] The existing installation devices for hanging components under steel beams still have the following shortcomings:

[0004] Most existing installation devices for hanging components under steel beams use bolts for fixing during installation. This fixing method is relatively troublesome, and when moving or disassembling the hanging components, the entire installation device needs to be disassembled, making it inconvenient to use as a whole.

[0005] When using existing steel cable under-hanging components, multiple support units are usually used at once. In order to better use the hanging components, the position of the hooks needs to be adjusted appropriately to adapt to different usage scenarios. The existing installation device for steel cable under-hanging components lacks this function.

[0006] When installing and using existing steel cable under-hanging components, different steel beams have different sizes, so the hanging components need to meet the installation work in different scenarios. The existing device structure is relatively simple and cannot be adapted to a variety of steel beams. At the same time, the device has poor stability. Summary of the Invention

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an installation device and method for suspending components under a steel beam, comprising a cooperating I-beam and two connecting middle ends, wherein the cooperating I-beam is a large load-bearing I-beam, and sliding steel shafts are fixedly connected to both sides of the connecting middle ends, and anti-detachment plates are fixedly connected to the ends of the two sliding steel shafts that are far apart from each other, an L-shaped clamping arm is provided on the sliding steel shaft, a cooperating sliding sleeve is provided on the L-shaped clamping arm, the cooperating sliding sleeve is slidably connected to the sliding steel shaft on the corresponding side, and a fastening shell is fixedly connected inside the connecting middle ends, and a cooperating locking mechanism and a mortise mechanism are provided inside the fastening shell;

[0008] Both of the two connecting ends are fixedly connected to mating toothed plates at their close proximity. A spacing control box is provided between the two mating toothed plates. A mating gear is rotatably connected inside the spacing control box. The two mating toothed plates mesh with the mating gear respectively. A self-locking mechanism is provided on the spacing control box.

[0009] Furthermore, the locking mechanism includes a bearing pull plate, a positioning shaft, a rotating port, and a bearing sliding sleeve. The two bearing pull plates are rotatably connected to both ends of the L-shaped clamping arm, the bearing sliding sleeve is slidably connected to the fastening housing, the two positioning shafts are fixedly connected to both sides of the fastening housing, the rotating port is set on the positioning shaft, and the positioning shaft is rotatably connected to the two bearing pull plates on the corresponding side.

[0010] Furthermore, two connecting brackets are fixedly connected to the bearing sleeve, and bearing ports are fixedly connected to the bottom of the two connecting brackets. A matching bracket is fixedly connected to the bottom of the bearing port, and the matching bracket has several circular notches.

[0011] Furthermore, the mortgage mechanism includes a limiting bushing, a mortgage disc, and a threaded rod. The limiting bushing is slidably connected to the fastening housing, the mortgage disc is fixedly connected to the top of the limiting bushing, the threaded rod is rotatably connected to the fastening housing, and the threaded rod is threadedly connected to the limiting bushing.

[0012] Furthermore, the threaded rod is coaxially fixedly connected to a driven bevel gear, and the inner wall of the fastening housing is rotatably connected to a driving bevel gear, which meshes with the driven bevel gear. An adjusting handle is rotatably connected to the fastening housing, and the rotating shaft of the adjusting handle passes through the fastening housing and is coaxially fixedly connected to the driving bevel gear.

[0013] Furthermore, the self-locking mechanism includes a rotating shaft cylinder, a return spring, a sliding plate, a connecting seat, and a positioning ring. The rotating shaft cylinder is rotatably connected to the spacing control box and is coaxially and fixedly connected to the mating gear. The return spring is disposed inside the rotating shaft cylinder. The sliding plate is slidably connected inside the rotating shaft cylinder and is movably connected to the return spring. The connecting seat is fixedly connected to the sliding plate, and the positioning ring is fixedly connected to the connecting seat.

[0014] Furthermore, the bottom of the positioning ring is provided with several positioning slots, and the spacing control box is provided with a positioning pin corresponding to the position of the positioning ring. The positioning pin is matched with the positioning slots. The rotating shaft is provided with a limit protrusion, and the sliding plate is slidably connected to the limit protrusion.

[0015] A method for installing a component hanging under a steel beam includes the following steps:

[0016] S1. In order to better explain the present invention, the introduction of the I-beam will facilitate the explanation of other components. During installation, the two L-shaped clamping arms on the two connecting middle ends need to be aligned with the bottom position of the I-beam and snapped together. In order for the L-shaped clamping arms to clamp and snap together the protruding position at the bottom of the I-beam, a load-bearing object needs to be placed on the bearing port or the mounting bracket. This is also the main purpose of this device.

[0017] S2, When the load is added, under the influence of gravity, the load-bearing sliding sleeve will slide down on the fastening shell through the connection of the connecting frame. Through the connection of the load-bearing pull plate, the two L-shaped clamping arms will approach each other on the sliding steel shaft, and the L-shaped clamping arms can be fixed at this time.

[0018] S3. In order to ensure the overall stability of the device, the adjustment handle needs to be turned manually. The driving bevel gear, which is fixedly connected to the adjustment handle on the same axis, will rotate, and the driven bevel gear that meshes with it will also rotate. Since the driven bevel gear is fixedly connected to the threaded rod on the same axis, the collapsing circular plate, which is threadedly connected to the threaded rod through the limit bushing, can move. When the collapsing circular plate abuts against the bottom of the matching I-beam, the overall stability of the device can be ensured.

[0019] S4. When it is necessary to adjust the distance between the two connecting ends for better use, simply pull the connecting seat out a certain distance so that the positioning card shaft is disengaged from the positioning card slot, and then rotate it to realize the rotation of the mating gear. When the mating gear rotates, the two mating tooth plates that mesh with it can drive the connecting ends to move closer or further apart, thereby realizing the control of the distance between the two connecting ends.

[0020] Compared with existing technologies, the advantages of this invention are:

[0021] This invention, by setting up a locking mechanism, uses the gravity of the load borne by the hanging component to pull the load-bearing plate, thereby ensuring the clamping stability of the L-shaped clamping arm. The installation is relatively convenient, and it can also be adapted to steel beams of different widths, greatly improving the adaptability and compatibility of the device.

[0022] This invention, by setting up a mortgage mechanism, allows the position of the mortgage disc to be adjusted by rotating the adjustment handle after basic installation is completed, so that the mortgage disc is tightly attached to the bottom of the steel beam, thereby improving the overall stability of the device.

[0023] This invention incorporates a self-locking mechanism. When the positions of the two connecting ends need to be adjusted, the connecting seat can be rotated for adjustment. At the same time, the positioning ring can cooperate with the positioning slot to position and lock the connecting seat, thereby preventing the connecting seat from rotating and further ensuring the safety and stability of the device.

Detailed Implementation

[0032] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention. Example 1

[0033] like Figures 1-6 As shown, an installation device for suspending components under a steel beam includes:

[0034] The system consists of an I-beam 1 and two connecting mid-ends 2. The I-beam 1 is a large load-bearing I-beam. Sliding steel shafts 3 are fixedly connected to both sides of the connecting mid-ends 2. Anti-detachment plates 4 are fixedly connected to the ends of the two sliding steel shafts 3 that are far apart from each other. L-shaped clamping arms 5 are provided on the sliding steel shafts 3. Matching sliding sleeves 6 are provided on the L-shaped clamping arms 5. Matching sliding sleeves 6 are slidably connected to the corresponding sliding steel shafts 3. A fastening housing 7 is fixedly connected inside the connecting mid-ends 2. A matching locking mechanism and a mortgage mechanism are provided inside the fastening housing 7.

[0035] Two connecting ends 2 are fixedly connected to mating toothed plates 8 at their close ends. A spacing control box 9 is provided between the two mating toothed plates 8. A mating gear 10 is rotatably connected inside the spacing control box 9. The two mating toothed plates 8 mesh with the mating gear 10 respectively. A self-locking mechanism is provided on the spacing control box 9. In order to better explain the present invention, the introduction of the mating I-beam 1 is used to better explain other components. During installation, the two L-shaped clamping arms 5 on the two connecting ends 2 need to be aligned with the bottom position of the mating I-beam 1 and snapped together. In order for the L-shaped clamping arms 5 to clamp and snap together the protruding position at the bottom of the mating I-beam 1, a load needs to be placed on the bearing port 16 or the mating bracket 17. This is also the main purpose of this device.

[0036] The locking mechanism includes a bearing pull plate 11, a positioning shaft 12, a rotating port 13, and a bearing sliding sleeve 14. The two bearing pull plates 11 are rotatably connected to the two ends of the L-shaped clamping arm 5. The bearing sliding sleeve 14 is slidably connected to the fastening housing 7. The two positioning shafts 12 are fixedly connected to both sides of the fastening housing 7. The rotating port 13 is set on the positioning shaft 12. The positioning shaft 12 is rotatably connected to the two bearing pull plates 11 on the corresponding side. Two connecting brackets 15 are fixedly connected to the bearing sliding sleeve 14. The bottom of the two connecting brackets 15 is fixedly connected to the bearing port 16. The bottom of the bearing port 16 is fixedly connected to the cooperating bracket 17. The cooperating bracket 17 has several circular notches 30. When the load is added, under the influence of gravity, the bearing sliding sleeve 14 will slide down on the fastening housing 7 through the connection of the connecting brackets 15. Through the connection of the bearing pull plates 11, the two L-shaped clamping arms 5 will approach each other on the sliding steel shaft 3. At this time, the L-shaped clamping arms 5 can be fixed.

[0037] The collateral mechanism includes a limiting bushing 18, a collateral circular plate 19, and a threaded rod 20. The limiting bushing 18 is slidably connected to the fastening housing 7. The collateral circular plate 19 is fixedly connected to the top of the limiting bushing 18. The threaded rod 20 is rotatably connected to the fastening housing 7 and threadedly connected to the limiting bushing 18. A driven bevel gear 21 is coaxially fixedly connected to the threaded rod 20. A driving bevel gear 22 is rotatably connected to the inner wall of the fastening housing 7, and the driving bevel gear 22 meshes with the driven bevel gear 21. An adjusting handle 23 is rotatably connected to the fastening housing 7, and the pivot of the adjusting handle 23 passes through... The outer casing 7 is fastened and fixedly connected to the driving bevel gear 22 on the same axis. At the same time, in order to ensure the overall stability of the device, the adjustment handle 23 needs to be manually rotated. The driving bevel gear 22, which is fixedly connected to the adjustment handle 23 on the same axis, will rotate, and the driven bevel gear 21 that meshes with it will also rotate. Since the driven bevel gear 21 is fixedly connected to the threaded rod 20 on the same axis, the collateral circular plate 19, which is threaded to the threaded rod 20 through the limit bushing 18, can move. When the collateral circular plate 19 abuts against the bottom of the matching I-beam 1, the overall stability of the device can be ensured.

[0038] The self-locking mechanism includes a rotating shaft cylinder 24, a return spring 25, a sliding plate 26, a connecting seat 27, and a positioning ring 28. The rotating shaft cylinder 24 is rotatably connected to the pitch control box 9 and is coaxially fixedly connected to the mating gear 10. The return spring 25 is disposed inside the rotating shaft cylinder 24. The sliding plate 26 is slidably connected inside the rotating shaft cylinder 24 and is movably connected to the return spring 25. The connecting seat 27 is fixedly connected to the sliding plate 26. The positioning ring 28 is fixedly connected to the connecting seat 27. Several positioning slots are provided at the bottom of the positioning ring 28. A positioning pin 29 is provided on the pitch control box 9 at the position corresponding to the positioning ring 28. The positioning pin 29 is matched with the positioning slot. A limit protrusion is provided inside the rotating shaft cylinder 24. The sliding plate 26 is slidably connected to the limit protrusion.

[0039] When it is necessary to adjust the distance between the two connecting ends 2 for better use, simply pull the connecting seat 27 out a certain distance so that the positioning pin 29 disengages from the positioning slot, and then rotate it to achieve the rotation of the mating gear 10. When the mating gear 10 rotates, the two mating tooth plates 8 that mesh with it can drive the connecting ends 2 to move closer or further apart, thereby achieving the control of the distance between the two connecting ends 2.

[0040] The working principle is as follows:

[0041] To better explain the present invention, the introduction of the I-beam 1 facilitates a better explanation of other components. During installation, the two L-shaped clamping arms 5 on the two connecting midpoints 2 need to be aligned with the bottom position of the I-beam 1 and engaged. In order for the L-shaped clamping arms 5 to clamp and engage with the protruding bottom position of the I-beam 1, a load-bearing object needs to be placed on the bearing port 16 or the mounting bracket 17. This is also the main purpose of this device.

[0042] When the load is added, under the influence of gravity, the load-bearing sleeve 14 will slide down on the fastening housing 7 through the connection of the connecting frame 15. Through the connection of the load-bearing pull plate 11, the two L-shaped clamping arms 5 will approach each other on the sliding steel shaft 3, and the L-shaped clamping arms 5 can be fixed at this time.

[0043] Meanwhile, in order to ensure the overall stability of the device, the adjustment handle 23 needs to be manually rotated. The driving bevel gear 22, which is coaxially fixed to the adjustment handle 23, will rotate, and the driven bevel gear 21 that meshes with it will also rotate. Since the driven bevel gear 21 is coaxially fixed to the threaded rod 20, the collateral round plate 19, which is threaded to the threaded rod 20 through the limit bushing 18, can move. When the collateral round plate 19 abuts against the bottom of the matching I-beam 1, the overall stability of the device can be ensured.

[0044] When it is necessary to adjust the distance between the two connecting ends 2 for better use, simply pull the connecting seat 27 out a certain distance so that the positioning pin 29 disengages from the positioning slot, and then rotate it to achieve the rotation of the mating gear 10. When the mating gear 10 rotates, the two mating tooth plates 8 that mesh with it can drive the connecting ends 2 to move closer or further apart, thereby achieving the control of the distance between the two connecting ends 2. Example 2

[0045] like Figure 7 As shown, based on Embodiment 1, the present invention provides a method for installing a device for suspending components under a steel beam, comprising the following steps:

[0046] S1. In order to better explain the present invention, the introduction of the I-beam 1 will facilitate the explanation of other components. During installation, the two L-shaped clamping arms 5 on the two connecting middle ends 2 need to be aligned with the bottom position of the I-beam 1 and snapped together. In order for the L-shaped clamping arms 5 to clamp and snap together the protruding position at the bottom of the I-beam 1, a load needs to be placed on the bearing port 16 or the mounting bracket 17. This is also the main purpose of this device.

[0047] S2, when the load is added, under the influence of gravity, the load-bearing sliding sleeve 14 will slide down on the fastening housing 7 through the connection of the connecting frame 15. Through the connection of the load-bearing pull plate 11, the two L-shaped clamping arms 5 will approach each other on the sliding steel shaft 3, and the L-shaped clamping arms 5 can be fixed at this time.

[0048] S3. In order to ensure the overall stability of the device, the adjustment handle 23 needs to be manually rotated. The driving bevel gear 22, which is coaxially fixed to the adjustment handle 23, will rotate, and the driven bevel gear 21 that meshes with it will also rotate. Since the driven bevel gear 21 is coaxially fixed to the threaded rod 20, the collateral round plate 19, which is threaded to the threaded rod 20 through the limit bushing 18, can move. When the collateral round plate 19 abuts against the bottom of the matching I-beam 1, the overall stability of the device can be ensured.

[0049] S4. When it is necessary to adjust the distance between the two connecting ends 2 for better use, simply pull the connecting seat 27 out a certain distance so that the positioning pin 29 is disengaged from the positioning slot, and then rotate it to realize the rotation of the mating gear 10. When the mating gear 10 rotates, the two mating tooth plates 8 that mesh with it can drive the connecting ends 2 to move closer or further apart, thereby realizing the control of the distance between the two connecting ends 2.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
