Manufacturer of finished fixed hinge support

First of all, 1
When selecting bearings, attention should be paid to the size of bearing capacity, vertical tension and horizontal force, as well as the displacement and rotation angle
For damping bearings, attention should also be paid to the horizontal elastic stiffness

2
When selecting bearings, attention should be paid to the types of bearings, i
e
two-way movable type, one-way movable type and fixed type

Fixed hinge support
The component and the support are connected by a smooth cylindrical hinge
The component cannot move in any direction, but can rotate around the pin
It can be seen that the restraint reaction force of the fixed hinge support is the same as that of the cylindrical hinge, that is, the restraint reaction force must act on the contact point and pass through the center of the pin, and the direction is uncertain

Therefore, it is necessary to assume decomposition when solving the support reaction force, and then solve the two components respectively to solve the total support reaction force
Characteristics of ball joint bearing: no rubber bearing, no influence of rubber aging on the bearing, and long service life; The spherical joint bearing has the performance of resisting vertical tension, so as to ensure that the upper and lower structures are not disconnected during vertical earthquake; The spherical joint support transmits force through the spherical surface, and there is no necking phenomenon of force, and the reaction force acting on the upper and lower structures is relatively uniform; Hinged bearing has good seismic performance; The hinged bearing has the performance of resisting horizontal force to ensure that the structure will not fall off in horizontal earthquake
