Description

Technical Field

[0001] This invention relates to the field of steel structure technology, and more specifically, to a height-adjustable universal bracket. Background Technology

[0002] A steel corbel is a short-arm-shaped protruding member in a steel structure, typically used to connect columns and beams or support other structural components. Its main function is to effectively transfer the loads borne by structural members such as beams and slabs, including their own weight and live loads, to the columns or other load-bearing members, making the stress distribution of the entire structure more clear and rational, and ensuring the stability of the structure.

[0003] Existing steel structure brackets are usually installed on columns by welding or bolting. When adjusting beams or other structures that require height or level adjustment, the height is usually adjusted by placing sleepers and the level is adjusted by inserting wedges.

[0004] However, these adjustment methods are cumbersome and difficult to adjust quickly and precisely. Furthermore, adjusting the level by inserting wedges can easily cause uneven force distribution at the support points or too small a force-bearing area, resulting in stress concentration and leading to local deformation and damage to the structure. Summary of the Invention

[0005] The present invention provides a height-adjustable universal bracket, which aims to solve the following problems: the existing adjustment methods for steel structure brackets are cumbersome and difficult to adjust quickly and precisely; moreover, the method of adjusting the level by inserting wedges can easily cause uneven force distribution at the support points or too small a force-bearing area, resulting in stress concentration, which in turn leads to local deformation and damage to the structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a height-adjustable universal bracket, comprising: a base, the base comprising two symmetrically arranged mounting plates, the mounting plates having mounting holes, a connecting plate being provided on one side of the two mounting plates that are close to each other, the connecting plate having positioning holes, the base further comprising a support plate, the support plate being horizontally arranged on one side of the two mounting plates that are close to each other;

[0009] In a preferred embodiment, the steering mechanism is a second steering assembly, which includes a spherical sleeve with a threaded tube at the bottom. A limit plate is provided on the threaded tube, and a guide rod is provided on the support plate. The guide rod is slidably connected to the limit plate.

[0010] In a preferred embodiment, a ball head is provided inside the spherical sleeve, and the ball head is fixedly connected to the top plate.

[0011] In a preferred embodiment, the top of the spherical sleeve is provided with a threaded groove, and a retaining ring is threadedly connected inside the threaded groove, the retaining ring being adapted to the ball head.

[0012] In a preferred embodiment, a lifting mechanism is provided on the mounting plate. The lifting mechanism includes two symmetrically arranged wedge plates, which are located on the outer sides of the corresponding mounting plates. A guide plate is provided on the mounting plate, which is adapted to the wedge plates. Two guide plates are slidably arranged on the wedge plates. The two wedge blocks are symmetrically arranged, and screw assemblies are threadedly connected to the two wedge blocks. A slider is slidably arranged in the vertical direction inside the guide plate, and the slider is slidably connected to the wedge blocks.

[0013] In a preferred embodiment, the rotating shaft is rotatably connected to the slider, the slider is provided with a limit rod, and the wedge plate is provided with a guide groove, the limit rod and the guide groove being adapted to each other.

[0014] In a preferred embodiment, the lifting mechanism further includes a threaded rod, which is rotatably mounted on a support plate and the support plate is perpendicular to the threaded rod. The threaded rod is adapted to a threaded tube.

[0015] In a preferred embodiment, the mounting plate is provided with a vibration mechanism, which includes two horizontal plates fixedly mounted on the connecting plate. The horizontal plates are horizontally positioned, and a top rod slides vertically on the horizontal plates, with the top end of the top rod abutting against the top plate.

[0016] In a preferred embodiment, a pressure plate is provided on the top rod, and a spring is provided on the side of the pressure plate that is close to the horizontal plate. The spring is movably sleeved on the top rod, and the bottom ends of the two top rods are fixedly connected to the same pull rod.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention, by setting a steering mechanism, eliminates the need for wedges, enabling rapid adjustment of the angle or level of a structure until the connection between the structure and the installation is aligned. Furthermore, by setting a lifting mechanism, the height of the structure can be quickly fine-tuned without the need for shims, making operation convenient.

[0019] This invention, by incorporating a vibration mechanism, enables workers to quickly adjust the fit between the top plate and the structure in confined spaces, even in situations where the bracket becomes difficult to turn due to insufficient lubrication caused by rust or dust and debris entering the component joints after prolonged use. This eliminates the need for workers to use hammers or other tools to strike the bracket. Attached Figure Description

[0032] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] In the specific construction of steel structures, corbel structures are usually used to support the structure. For example, when installing a beam on a column, two corbels are usually used to pre-support the beam to facilitate subsequent welding or bolt installation. At the same time, before installing the beam, the angle and level of the beam need to be adjusted to match the preset installation position on the column. Therefore, the beam still needs to be slightly adjusted on the corbels.

[0034] Example 1

[0035] Refer to the instruction manual appendix Figures 1 to 11 This embodiment proposes a height-adjustable universal bracket to solve the problem that in the prior art, the fixed top plate on the steel structure bracket can only be adjusted by inserting wedges or shims to adjust the level or angle of the structure. The operation steps are cumbersome and can easily lead to uneven force distribution at the support point or too small force area, resulting in stress concentration, which in turn leads to local deformation and damage of the structure after installation.

[0036] Includes: a base 1, which includes two symmetrically arranged mounting plates 11, each mounting plate 11 having mounting holes 12, and a connecting plate 13 on one side of the two mounting plates 11 that is close to each other, the connecting plate 13 having positioning holes 14.

[0037] It should be noted that the number, position, and size of the mounting holes 12 can be adjusted according to the actual situation so that the bracket can be easily fixedly connected to different installation objects, such as I-beam columns. The number, installation position, and specifications of the connecting plates 13 can also be adjusted according to the actual situation.

[0038] The mounting plate 11 is provided with a steering mechanism 3, and the execution end of the steering mechanism 3 is provided with a top plate 4, which is used to support the component to be supported.

[0039] The steering mechanism 3 includes a steering assembly 31, which includes a rotating shaft 311 horizontally mounted on a mounting plate 11. A rotating plate 312 is fixedly mounted on the rotating shaft 311, and a rotating plate 313 is fixedly mounted on the rotating plate 312. A rotating shaft 314 is rotatably mounted on the rotating plate 313, and the rotating shaft 314 is perpendicularly intersecting the rotating shaft 311. A rotating plate 315 is fixedly mounted on the rotating shaft 314, and a top plate 4 is provided on the top of the rotating plate 315. A fixing hole 316 is provided on the rotating plate 315, which is adapted to the positioning hole 14.

[0040] It should be noted that the first rotating shaft 311 is the main support component of the top plate 4, which is used to transmit the pressure of the top plate 4 to the mounting plate 11. At the same time, the top plate 4 can rotate along the axis of the first rotating shaft 311. Furthermore, the top plate 4 can rotate along the axis of the second rotating shaft 314. The combination of the two enables the top plate 4 to have rotation functions in both the X-axis and Y-axis directions.

[0041] It should also be noted that the positioning hole 14 and the fixing hole 316 can be connected by a pin to pre-fix the angle of the top plate 4.

[0042] In this embodiment, the specific implementation scenario is as follows: First, the required bracket is installed on a preset installation object, such as an I-beam column, by means of bolt connection or welding. In the initial state, the top plate 4 is movable. The top plate 4 can be initially kept horizontal by passing the pin through the positioning hole 14 and the fixing hole 316. Then, the structure, such as a beam, can be placed on the top plate 4. When it is necessary to adjust the angle of the structure, the pin is removed, and then pressure is applied to the structure towards the top plate 4, so that the structure and the upper surface of the top plate 4 can automatically and fully fit together, thereby effectively increasing the contact area between the two. At this time, the top plate 4 can provide stable support for the structure. Moreover, since the top plate 4 is movable at this time, the angle or level of the structure can be quickly adjusted by the worker applying a certain external force to the structure without the need for wedges, until the connection position of the structure and the installation object is aligned. At this time, the connection between the structure and the installation object can be easily completed.

[0043] Example 2

[0044] Based on Example 1, refer to the appendix of the specification. Figures 1 to 11 This embodiment proposes a lifting mechanism 2 to solve the problem in the prior art that after the bracket has initially fixed the structure, the structure can only be finely adjusted in height by inserting shims or other supports.

[0045] A lifting mechanism 2 is provided on the mounting plate 11. The lifting mechanism 2 includes two symmetrically arranged wedge plates 21, which are located on the outer side of the corresponding mounting plate 11. A guide plate 23 is provided on the mounting plate 11, which is adapted to the wedge plates 21. Two guide plates 23 are slidably arranged on the wedge plates 21. Two wedge blocks 24 are symmetrically arranged, and screw assemblies 25 are threadedly connected to the two wedge blocks 24. A slider 26 is slidably arranged in the vertical direction inside the guide plate 23. The slider 26 is slidably connected to the wedge blocks 24. A rotating shaft 311 is rotatably connected to the slider 26. A limit rod 27 is provided on the slider 26. A guide groove 22 is provided on the wedge plate 21, and the limit rod 27 is adapted to the guide groove 22.

[0046] It should be noted that the wedge plate 21 is in the shape of an inverted V. By having two wedge blocks 24 move synchronously in the horizontal direction on the wedge plate 21, the slider 26 can be pushed to move back and forth in the vertical direction, thereby making it easy to adjust the height of the top plate 4.

[0047] It should also be noted that the screw assembly 25 includes a threaded rod and a nut, which are well-known and mature technologies in the art, and will not be described in detail in this embodiment. The self-locking property of the nut and the thread can fix the adjusted height.

[0048] It should also be noted that the cooperation between the limiting rod 27 and the guide groove 22 can facilitate the guidance of the slider 26.

[0049] Example 3

[0050] Based on Example 2, refer to the appendix of the specification. Figures 1 to 11 This embodiment also proposes a second steering component 32 to replace the first steering component 31, thereby achieving the same or similar functions with different structures, and thus effectively improving the practicality of the equipment.

[0051] The base 1 also includes a support plate 15, which is horizontally arranged on one side of the two mounting plates 11 that are close to each other. The lifting mechanism 2 also includes a threaded rod 28, which is rotatably arranged on the support plate 15 and the support plate 15 and the threaded rod 28 are arranged perpendicularly. The steering mechanism 3 also includes a second steering assembly 32, which includes a spherical sleeve 321. The bottom of the spherical sleeve 321 is provided with a threaded tube 325, which is adapted to the threaded rod 28.

[0052] It should be noted that the height of the top plate 4 can also be easily adjusted by rotating the threaded rod 28 in conjunction with the threaded tube 325.

[0053] A limit plate 326 is provided on the threaded pipe 325, and a guide rod 16 is provided on the support plate 15. The guide rod 16 is slidably connected to the limit plate 326.

[0054] It should be noted that by cooperating with the guide rod 16, the limiting plate 326 can guide and limit the threaded tube 325, thereby improving the stability of the bracket.

[0055] A ball head 323 is provided inside the spherical sleeve 321, and the ball head 323 is fixedly connected to the top plate 4.

[0056] The top of the spherical sleeve 321 is provided with a threaded groove 322, and a retaining ring 324 is threadedly connected to the threaded groove 322. The retaining ring 324 is adapted to the ball head 323.

[0057] It should be noted that a friction pad, such as a rubber pad, is also provided on the inner wall of the fixing ring 324 to increase the friction between the fixing ring 324 and the ball head 323, thereby increasing the support stability of the bracket; this structure is suitable for use in scenarios where there are many connection points between the structure and the installation.

[0058] Example 4

[0059] Based on Example 3, refer to the appendix to the specification. Figures 1 to 11 This embodiment proposes a vibration mechanism 5 to solve the problem in the prior art where, after long-term use, the corbel becomes difficult to turn due to insufficient lubrication caused by rust or dust and debris entering the component connection. At this time, the top plate 4 is prone to not fully fitting with the structure. The prior art generally requires workers to use tools such as hammers to strike the corbel, but in some narrow construction positions, it is inconvenient for workers to move their hands and feet.

[0060] The mounting plate 11 is provided with a vibration mechanism 5. The vibration mechanism 5 includes two horizontal plates 51 fixedly mounted on the connecting plate 13. The horizontal plates 51 are horizontally mounted, and a top rod 52 slides vertically on the horizontal plates 51. The top end of the top rod 52 abuts against the top plate 4.

[0061] It should be noted that a striking block made of elastic material, such as a rubber hammer, can be installed at the top of the top rod 52 to reduce the possibility of damage to the top plate 4.

[0062] A pressure plate 53 is provided on the top rod 52. A spring 54 is provided on the side of the pressure plate 53 that is close to the horizontal plate 51. The spring 54 is movably sleeved on the top rod 52.

[0063] The bottom ends of the two top rods 52 are fixedly connected to the same pull rod.

[0064] It should be noted that workers can pull the lever to simultaneously control the two top rods 52 to strike the top plate 4, causing the top plate 4 to vibrate. This, in turn, adjusts the contact angle between the top plate 4 and the surface of the structure, ensuring that the top plate 4 can make full contact with the surface of the structure. This provides uniform support to the structure and improves the overall support stability of the corbel.

[0065] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
