Description
[ field of technology ]
The utility model relates to the technical field of anti-seismic foundation bolts, in particular to the technical field of anti-seismic foundation bolts.
[ background Art ]
According to the connection relation between the foundation bolts and the concrete foundation, the foundation bolts can be divided into two types of fixed connection type and non-fixed connection type.
The fixed connection type foundation bolt is used for fixedly mounting mechanical equipment on a concrete foundation at a certain position, one end of the foundation bolt is in threaded connection with a mechanical component, the other end of the foundation bolt is buried in the concrete, and the foundation bolt can be generally divided into a fixed foundation bolt, a movable foundation bolt, an expansion anchor foundation bolt and an adhesive foundation bolt. The fixed foundation bolts and the movable foundation bolts are used together with concrete foundation for pouring, and are used for fixing mechanical equipment which can generate stronger vibration or impact in the working; and the expansion anchor foundation bolt and the bonding foundation bolt are buried after being drilled on the concrete foundation and are used for fixing static equipment.
Whereas non-fixed connection anchor bolts generally include a base and a stud fixedly mounted on the base, the stud being connected to the apparatus. Such anchor bolts are mounted at the bottom of the equipment to create a gap between the equipment and the ground, facilitating movement of the equipment when needed using a cart. However, such anchor bolts are not resistant to vibration and shock generated when transferring equipment.
However, although the existing foundation bolt can resist vibration to a certain extent in the use process, the anti-seismic structure is too simple, and the anti-seismic effect with poor effect caused by the simple anti-seismic structure is not ideal in use, so that the problems of damage, fracture and the like in the interior due to vibration are very easy to occur when the foundation bolt is subjected to repeated vibration or continuous vibration.

Although the above products are somewhat resistant to vibration, there are still some drawbacks: (1) the tightness between the vertical sliding block and the vertical sliding groove on the side wall of the foundation bolt body is insufficient, external water vapor is easy to enter the base to corrode stress points of the anti-seismic mechanisms (2) such as the anti-seismic mechanism and the like and is located at the edge, the anti-seismic mechanism is unevenly stressed for a long time, the anti-seismic mechanism is easy to wear (3) and is not directly connected with the movable block matched with the anti-seismic mechanism, and therefore, when the foundation bolt just begins to descend, the anti-seismic mechanism cannot exert an anti-seismic function.
Therefore, in order to solve the above-mentioned problems, it is necessary to provide an anti-seismic anchor bolt having better performance.
