Description

Technical Field

[0001] This utility model belongs to the technical field of crossbeam supports, and particularly relates to a crossbeam support for an arched structure of steel. Background Technology

[0002] As one of the components of a steel structure, the steel beam is a structure mainly composed of steel materials and is one of the main types of building structures. Steel beams have high strength and high elastic modulus. Compared with wood, its density-to-yield strength ratio is relatively low. Therefore, under the same stress conditions, steel structure components have small cross sections, light weight, and are easy to transport and install, making them highly practical. Steel structure beams require supports for support. Existing steel structure supports, such as the arch beam support for a steel structure disclosed in Chinese Patent Publication No. CN219316025U, include a fixed plate. Support legs are fixedly installed on both sides of the bottom outer wall of the fixed plate. Each set of support legs is equipped with a base. Fixed columns are symmetrically fixedly installed on both sides of the top of the fixed plate. Dampers are installed inside the two sets of fixed columns through shock-absorbing components. Movable inner rods are fixedly installed at the top of the two sets of dampers. The tops of the movable inner rods are fixedly installed on both sides of the bottom outer wall of a U-shaped support plate. A U-shaped plate is installed at the top of the U-shaped support plate through a disassembly and assembly component. By using the elastic potential energy of the dampers in conjunction with the sliding action of the slider and the sliding rod, the vibration of the beam chord can be relatively stably reduced to reduce the vibration of other parts of the device, thereby further enhancing the stability of the device during use. However, the arch beam support of this technology can only fix beams of one size. In actual construction, beams of different sizes are used due to requirements and layout issues. Therefore, multiple different supports are needed for fixing. Matching the models is troublesome and the operation steps are complicated. If the support and beam size do not match, the beam is easy to shake, affecting the building structure and making it not very practical. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a support for the arch beam of a steel structure.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0034] like Figure 1-4 As shown, a steel structure arch beam support includes a base 1, a U-shaped seat 2 fixedly mounted on the base 1, a U-shaped groove 21 opened on the inner side of the U-shaped seat 2, a first arc-shaped block 3 slidably mounted in the U-shaped groove 21, three first arc-shaped blocks 3 evenly arranged in the U-shaped groove 21, a first sliding groove 31 opened on the first arc-shaped block 3, and a second arc-shaped block 4 slidably mounted in the first sliding groove 31.

[0035] The base 1 has three receiving slots 11, which correspond to the distribution of the first arc-shaped blocks 3. Each receiving slot 11 is provided with a set of driving mechanisms 5. The first arc-shaped blocks 3 and the second arc-shaped blocks 4 are both connected to the driving mechanisms 5. Under the drive of the driving mechanisms 5, the first arc-shaped blocks 3 and the second arc-shaped blocks 4 can slide towards the center of the U-shaped seat 2.

[0036] With the above technical solution, when the diameter of the crossbeam is smaller than the diameter of the U-shaped seat 2, the first arc block 3 is driven by the drive mechanism 5 to slide in the U-shaped groove 21. The top of the first arc block 3 slides out of the U-shaped groove 21 and slides towards the center of the U-shaped seat 2. The second arc block 3 moves together with the first arc block 3. After the three first arc blocks 3 have slid, the diameter of the top support surface becomes smaller, which can provide better support for the side of the crossbeam. If it is necessary to further reduce the diameter, the second arc block 4 is driven by the drive mechanism 5 to slide in the first sliding groove 31. The diameter of the support surface composed of the three second arc blocks 4 becomes smaller again, providing more close support for the side of the smaller diameter crossbeam.

[0037] Preferably, a first groove 32 is provided at the bottom of the first arc-shaped block 3, and a first connecting plate 6 is connected between adjacent first arc-shaped blocks 3. The two ends of the first connecting plate 6 are slidably connected to the first groove 32 of the corresponding first arc-shaped block 3, thereby improving the stability of the connection between adjacent first arc-shaped blocks 3.

[0038] Preferably, a second groove 41 is provided at the bottom of the second arc-shaped block 4, and a second connecting plate 7 is connected between adjacent second arc-shaped blocks 4. The two ends of the second connecting plate 7 are slidably connected to the second groove 31 of the corresponding second arc-shaped block 4, thereby improving the stability of the connection between adjacent second arc-shaped blocks 4.

[0039] Preferably, the top of the second arc-shaped block 4 is provided with a damping pad 42, which is in direct contact with the side of the crossbeam to increase friction and improve the stability of the crossbeam.

[0040] Preferably, the drive mechanism 5 includes a first moving rod 51, one end of the first moving rod 51 passes through the U-shaped seat 2 and is fixedly connected to the first arc-shaped block 3, one end of the first moving rod 51 is connected to a first threaded rod 52, and a first threaded sleeve 53 is rotatably provided in the receiving groove 11, and the first threaded sleeve 53 is threadedly connected to the first threaded rod 52.

[0041] The first moving rod 51 is slidably fitted with the second moving rod 54. One end of the second moving rod 54 passes through the first arc-shaped block 4 and is fixedly connected to the second arc-shaped block 4. The other end of the second moving rod 54 is connected to the second threaded rod 55. The second threaded sleeve 56 is rotatably provided in the receiving groove 11. When the second threaded rod 55 moves to the second threaded sleeve 56, it is threadedly connected to the second threaded sleeve 56.

[0042] Rotating the first threaded sleeve 53 causes the first threaded rod 52 to move along the axis of the first threaded sleeve 53 under the action of the thread, pushing the first moving rod 51 to move and causing the first arc-shaped block 3 to move. Because the first arc-shaped block 3 drives the second arc-shaped block 4 to move synchronously, the second moving rod 54 slides inside the first moving rod 51. When the first arc-shaped block 3 moves to the designated position, the second threaded rod 55 moves to the position connected with the second threaded sleeve 56. If it is necessary to continue moving the second arc-shaped block 4, it can be achieved by rotating the second threaded sleeve 56.

[0043] Preferably, the first threaded sleeve 53 and the second threaded sleeve 56 have the same diameter, and the first threaded rod 52 and the second threaded rod 55 have the same diameter.

[0044] Preferably, a first transmission belt 57 is provided between adjacent first threaded sleeves 53, and a second transmission belt 58 is provided between adjacent second threaded sleeves 56. By rotating one of the first threaded sleeves 53 or the second threaded sleeve 56, the other two first threaded sleeves 53 or the second threaded sleeve 56 can be rotated synchronously.

[0045] The base 1 is equipped with a corresponding rotating rod, which guides the connection direction of the first transmission belt 57 or the second transmission belt 58.

[0046] Preferably, multiple support rods 12 are fixedly provided on both sides of the base 1. The support rods 12 form an acute angle with the side of the base 1, which provides support for the base 1.

[0047] The working principle of this utility model is as follows: When it is necessary to support beams of different sizes, the first threaded sleeve 53 is rotated, and the first threaded rod 52 moves along the axis of the first threaded sleeve 53 under the action of the thread, pushing the first moving rod 51 to move. The top of the first arc-shaped block 3 slides out of the U-shaped groove 21 and slides towards the center of the U-shaped seat 2. The second arc-shaped block 3 moves together with the first arc-shaped block 3. Because the first arc-shaped block 3 drives the second arc-shaped block 4 to move synchronously, the second moving rod 54 slides inside the first moving rod 51. After the three first arc-shaped blocks 3 have slid, the diameter of the top support surface becomes smaller, which can provide better support for the side of the beam. If it is necessary to further reduce the diameter, when the first arc-shaped block 3 moves to the designated position, the second threaded rod 55 moves to the position connected with the second threaded sleeve 56. If it is necessary to continue to move the second arc-shaped block 4, the second arc-shaped block 4 can slide in the first sliding groove 31 by rotating the second threaded sleeve 56. The diameter of the support surface composed of the three second arc-shaped blocks 4 becomes smaller again, providing more close support for the side of the beam with a smaller diameter.

[0048] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
