Abstract
The utility model discloses a vertical beam falling-resistant device for a bridge, which comprises a beam body tensile seat (1), an abutment wall tensile seat (2) and a buffering component, wherein two ends of a buffering component are respectively connected with the beam body tensile seat (1) and the abutment wall tensile seat (2), the beam body tensile seat (1) is provided with a connecting board (1a), the connecting board (1a) is provided with a groove way hole (1b), and a connection end of the buffering component can horizontally and freely slide in the groove way hole (1b). The vertical beam falling-resistant device is simple and practical in structure, the aims of the vertical beam falling resistance and the shock absorption can be achieved, and the movement of the beam body relative to the abutment wall in a normal range can be guaranteed.
Description
Technical field
The utility model belongs to the bridge technology field, relates to the vertical anti-fall girder apparatus of a kind of bridge concretely.
Background technology
Anti-fall girder apparatus is one of important composition parts in bridge and the construction work, and its effect is to make the suffered seismic forces of beam body can play buffering when violent earthquake, guarantees simultaneously not skid off bridge pier or abutment at violent earthquake back rest body.
Traditional anti-fall girder apparatus mainly comprises beam body tension seat, pier tension seat and round-link chain, and the round-link chain two ends are connected with pier tension seat with described beam body tension seat respectively, are enclosed with yielding rubber on the described round-link chain.What be provided with on its central sill body tension seat is pre-buried dowel, traditional anti-fall beam mainly plays the cushioning effect of horizontal direction, can not adapt to damping requirement at vertical direction, reason is a kind of connected mode that is inclined cross the anti-fall girder apparatus employing, what just form between buffer structure in the anti-fall girder apparatus and pier and the beam body tie point is similar leg-of-mutton position relation, this kind structure makes buffer structure be in the purpose that relaxed state does not have buffering at vertical direction, and this structure can not satisfy the normal displacement request of beam body again if vertically connect this structure employing so.
The utility model content
The purpose of this utility model has been to provide the vertical anti-fall girder apparatus of bridge that plays vertical damping purpose under a kind of simple in structure, prerequisite that can satisfy beam body normal displacement requirement.
The technical solution of the utility model is as follows:
The vertical anti-fall girder apparatus of a kind of bridge, comprise beam body tension seat, pier tension seat and Buffer Unit, described Buffer Unit two ends are connected with pier tension seat with described beam body tension seat respectively, described beam body tension seat has junction plate, have the conduit hole on this junction plate, the link of described Buffer Unit can level be free to slide in described conduit hole.
Adopt said structure, this anti-fall girder apparatus adopts vertical connected mode between beam body and pier, can regulate the length of Buffer Unit according to difference in height between beam body and the pier, key in this programme also is, on the junction plate of beam body tension seat, also have the conduit hole, Buffer Unit is articulated on the described conduit hole and can level be free to slide in described conduit hole, has also satisfied horizontal relative displacement between the normal and pier of beam body simultaneously reaching vertical anti-fall beam damping purpose like this.
Described Buffer Unit comprises hook ring and buffering ring, and described hook ring is articulated in the described conduit hole by the hook ring bolt, is set with wear-resistant sleeve on the wherein said hook ring bolt.
Hook ring is by the free horizontal slip in described conduit hole of hook ring bolt, and wear-resistant sleeve plays the effect of protection connecting portion.
Described hook ring and described buffering ring articulate, and the changeover portion that articulates of described buffering ring and described hook ring is enclosed with yielding rubber.
Can satisfy the requirement of differing heights difference by increasing the length that chain link is regulated Buffer Unit between buffering ring and the described hook ring.
Described pier tension seat is provided with the pier junction plate, and described buffering ring is connected with described pier junction plate by connecting bolt.
Described beam body tension seat is provided with beam body cast-in fixing bolt, and described pier tension seat is provided with the pier cast-in fixing bolt.
Beneficial effect: the utility model is simple in structure, practical, guaranteed the displacement of pier relatively in normal range (NR) of beam body when reaching vertical anti-fall beam damping purpose.
