Description

Technical Field

[0001] This utility model belongs to the technical field of cantilever beam and column connection, and in particular relates to a hinged joint between a cantilever beam and a column. Background Technology

[0002] The hinged joint between the cantilever beam and the column is a connection method that allows only vertical shear force to be transmitted between the cantilever beam and the column, while the included angle between the beam and the column axis can be freely changed. The cantilever beam is usually reserved with a lug plate for connection with the column. Since the column needs to be installed with the ground, a lug plate is also welded to the top of the column for the installation of the lug plate on the cantilever beam. There may be slight deviations in the mounting holes on the two lug plates, which increases the difficulty of their connection. Therefore, we designed a hinged joint between the cantilever beam and the column. The lug plate on the steel column can be adjusted back and forth and left and right to adapt to the connection and installation of the lug plate on the cantilever beam. Utility Model Content

[0003] The purpose of this utility model is to provide a hinged joint between a cantilever beam and a column, which has the advantage that the ear plate on the steel column can be adjusted forward, backward, left, and right to adapt to the butt joint installation of the ear plate on the cantilever beam, so as to solve the above-mentioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hinge joint between a cantilever beam and a column includes a fixed plate welded to the top of the column and mounting ears installed below the cantilever beam by four bolts. A movable plate is provided above the fixed plate. Screw rods are welded to the four corners of the bottom of the movable plate. Long grooves are opened on both sides of the top of the fixed plate. Two screw rods are slidably connected to the inner cavity of the long grooves. Nuts that abut against the bottom of the fixed plate are threaded to the surface of the screw rods. A movable connecting ear seat is provided on the top of the movable plate. The bottom of the mounting ear extends into the inner cavity of the connecting ear seat. A hinge pin is passed through both the mounting ear and the connecting ear seat. A rectangular cavity is opened on the top of the movable plate. A threaded rod is rotatably connected to the inner cavity of the rectangular cavity. A threaded slider that is threaded to the surface of the threaded rod is fixedly connected to the bottom of the connecting ear seat.

[0005] Preferably, the end of the threaded rod extends through to the outside of the movable plate and is fixedly mounted with a hexagonal rotating block.

[0006] Preferably, baffles are provided on both sides of the connecting ear seat, and the baffles cover the top of the rectangular cavity.

[0007] Preferably, both the connecting ear and the mounting ear have through holes for the hinge pin to pass through.

[0008] Preferably, multiple reinforcing ribs are welded between the fixing plate and the column.

[0009] The beneficial effects of this utility model are: 1. This utility model adjusts the position of the connecting ear seat by moving the movable plate one after another, and the moving plate can be locked by the screw rod. Then, the position of the connecting ear seat can be adjusted left and right by rotating the threaded rod and moving the threaded slider, so that the through hole on the connecting ear seat is aligned with the through hole on the mounting ear, which facilitates the installation of the hinge pin. This achieves the purpose of adjusting the ear plate on the steel column to fit the ear plate on the cantilever beam for docking installation. 2. By setting a hexagonal rotating block, this utility model allows the threaded rod inside the rectangular cavity to be rotated by using a wrench on the surface of the hexagonal rotating block, thus providing a force application point for operating the threaded rod; 3. By setting up a baffle, the baffle will move when the connecting ear seat moves left and right, which can ensure that the baffle can cover the rectangular cavity and effectively prevent external impurities from entering the inner cavity of the rectangular cavity and affecting the operation of the threaded rod.

Detailed Implementation

[0012] In the following description, embodiments of the hinged joint between the cantilever beam and the column of this utility model will be described with reference to the accompanying drawings.

[0013] Figure 1-4This invention illustrates a hinge joint between a cantilever beam and a column according to an embodiment of the present invention. It includes a fixed plate 2 welded to the top of the column 1 and mounting ears 5 installed below the cantilever beam 3 by four bolts 4. Multiple reinforcing ribs 17 are welded between the fixed plate 2 and the column 1. A movable plate 6 is positioned above the fixed plate 2. Screw rods 7 are welded to the four corners of the bottom of the movable plate 6. Long slots 8 are formed on both sides of the top of the fixed plate 2. Two screw rods 7 are slidably connected to the inner cavity of the long slots 8. Nuts that abut against the bottom of the fixed plate 2 are threaded onto the surface of the screw rods 7. A movable connecting ear 9 is provided at the top of the movable plate 6. The bottom of the mounting ears 5 extends into the inner cavity of the connecting ear 9. A hinge pin 10 passes through both the mounting ear 5 and the connecting ear 9. Through holes 16 are formed on both the connecting ear 9 and the mounting ear 5 for the hinge pin 10 to pass through. A rectangular cavity 11 is provided at the top of the 6. A threaded rod 12 is rotatably connected to the inner cavity of the rectangular cavity 11. Baffles 15 are provided on both sides of the connecting ear 9. The baffles 15 cover the rectangular cavity 11. As the connecting ear 9 moves left and right, the baffles 15 will move, ensuring that the baffles 15 can cover the rectangular cavity 11 and effectively prevent external impurities from entering the inner cavity of the rectangular cavity 11 and affecting the operation of the threaded rod 12. A threaded slider 13 is fixedly connected to the bottom of the connecting ear 9 and threaded to the surface of the threaded rod 12. The end of the threaded rod 12 extends to the outside of the moving plate 6 and is fixedly installed with a hexagonal rotating block 14. With the setting of the hexagonal rotating block 14, the threaded rod 12 in the inner cavity of the rectangular cavity 11 can be rotated by using a wrench on the surface of the hexagonal rotating block 14, providing a force application point for operating the threaded rod 12.

[0014] Working principle: When using this utility model, the fixing plate 2 is welded to the bottom of the column 1 and the column 1 is fixed to the ground by the pre-embedded anchor bolts. First, the mounting ear 5 is fixedly installed under the cantilever beam 3 by the bolt 4. The threaded rod 12 is rotated in advance, and the threaded slider 13 on the surface of the threaded rod 12 causes the connecting ear 9 to move left and right on the top of the moving plate 6. After the connecting ear 9 is adjusted to a suitable position, the moving plate 6 is picked up so that the screw rod 7 at the bottom of the moving plate 6 is placed in the inner cavity of the long groove 8 on the fixing plate 2. The moving plate 6 is moved back and forth to adjust the position of the connecting ear 9 so that the through hole 16 on the connecting ear 9 is aligned with the through hole 16 on the mounting ear 5. Then, the hinge pin 10 is inserted to complete the installation.

[0015] In summary: the hinge joint between the cantilever beam and the column can be adjusted by moving the movable plate 6 to adjust the position of the connecting lug 9, and the movable plate 6 can be locked in place by the screw rod 7. Then, the position of the connecting lug 9 can be adjusted left and right by rotating the threaded rod 12 and moving the threaded slider 13, so that the through hole 16 on the connecting lug 9 is aligned with the through hole 16 on the mounting ear 5, which facilitates the installation of the hinge pin 10. This achieves the purpose of adjusting the lug plate on the steel column to fit the connecting lug plate on the cantilever beam.
