In the utility model, with arc-shaped steel lath 5 with the use of ball steel support be any one in bi-directional movable type, one-way movable type or fixed.
In the utility model, the arc-shaped steel lath 5 being arranged on ball steel support both sides uses single wider arc-shaped steel lath, or needs according to designing and calculating the arc-shaped steel lath using many arrangements.
The advantage of the technical scheme that the utility model provides:
1) outside its own advantages remaining common ball steel support, there is reciprocating motion when earthquake occurs by the arc-shaped steel lath set up between upper and lower seat board and play increase Damping work seismic energy, reduce the cushioning effect of slide displacement, relative displacement between the upper and lower seat board of bearing can be limited simultaneously within a controlled scope, prevent beam.
2) arc-shaped steel lath makes final molding shape in advance according to design size, and is connected and fixed by securing cover plate between upper and lower seat board, can either ensure the precision of size like this, facilitates again the assembling of arc-shaped steel lath.
3) compare the stopping means such as block, arc-shaped steel lath constitutive relation is clear, and force path is clear and definite, determines to design displacement, the balance of realizable force and displacement by calculating, and do not bend at the bottom of protection pier destruction and shear failure.
4) arc-shaped steel lath has price advantage, and can realize easy replacing in the holder, very easy to use.
In a word, the utility model is applicable on the building of urban viaduct, road bridge, railway bridge and various large-scale suspension frame structure and so on, plays cushioning effect.
