Description

Technical Field

[0001] The utility model relates to the technical field of connectors in seismic brackets, and particularly relates to a novel hinge. Background Art

[0002] A seismic bracket is a device specifically designed to restrict the movement of attached mechanical and electrical engineering facilities in a building, control their vibrations during an earthquake, and safely transfer the loads of these facilities to the building's structure. During an earthquake, the seismic bracket can provide stable protection for the mechanical and electrical engineering facilities of the building and resist vibration impacts from different directions. During design, precise calculations and verifications are required based on the loads to be borne by the bracket. All components constituting the seismic bracket should be prefabricated finished products, and the fasteners connecting these components should be designed to be easy to install and operate. Most of the fasteners use hinges for connection. Therefore, while providing hinge freedom of rotation, the hinge also needs to ensure axial and radial connection strength and provide sufficient longitudinal and lateral seismic support. Existing seismic hinges generally simply use bolts passing through through-holes to connect two link plates. This structure is inconvenient for installation, and the radial shear force at the hinge hole position is completely borne by the bolts. Also, because the connection position between the hinge hole and the bolt is prone to rust, bolt fracture and other problems are likely to occur under the action of the radial shear force, thereby affecting the overall structural stability and safety of the seismic bracket.

Specific embodiments

[0022] The following is a further detailed description through specific embodiments:

[0023] Embodiment 1

[0024] As shown in Figure 1-2 Figures 4 and 5, this embodiment shows a new type of hinge, including a first hinge 1 and a second hinge 2 hinged to each other by bolts. During the installation process, the seismic hinge can flexibly adjust the angle according to the on-site installation conditions without welding. At the same time, in the event of an earthquake or other vibrations, the seismic hinge can absorb and disperse the vibration energy through its rotatable characteristics, reducing the impact on pipelines and equipment.

[0025] In this embodiment, the first hinge 1 includes a first mounting plate 11, a first hinge plate 12, and a first connecting plate 13 disposed between the first mounting plate 11 and the first hinge plate 12, and the three are integrally formed and connected; in this embodiment, the first mounting plate 11 and the first hinge plate 12 are perpendicularly arranged; the first mounting plate 11 is threadedly connected to the U-shaped pipe hanger 3; the first hinge plate 12 includes a cylindrical first reinforcing boss 121 fixedly disposed on the side close to the second hinge 2 and a first hinge through hole 122 penetrating through the first reinforcing boss 121 and the first hinge plate 12 along the axis of the first reinforcing boss 121.

While ensuring the rotational freedom at the hinge, axial and radial supporting forces are provided, improving the reliability of the overall structure. When vibration occurs, the first reinforcing boss 121 can assist the bolt in bearing the radial shear force of the hinge surface, thereby improving the stability and service life of the hinge. Secondly, the pre-installation between the first reinforcing boss 121 and the second hinge through-hole 221 completes the quick alignment of the first hinge 1 and the second hinge 2, facilitating the subsequent bolt hinge installation between the two.
