Embodiment Construction

[0014] The limit slide plate support of the present invention is composed of a top steel component, a bottom steel component, a tetrafluororubber slide plate, a steel rod and an anchoring device. It is characterized in that: the top steel component passes through the top sleeve 4 and the top anchor rod 5 The top steel plate 1 is formed by bolting with the top anchor bolt 6, wherein the top bump 2, the stainless steel plate 3, the top sleeve 4 and the top steel plate 1 are all welded, and the bottom steel assembly is passed through the bottom sleeve by the bottom anchor rod 10 The cylinder 9 and the bottom steel plate 7 are formed by bolting with the bottom anchor bolt 11, wherein the bottom bump 8, the bottom sleeve 9 and the bottom steel plate 7 are all welded, and the tetrafluororubber slide plate is adhered on the top of the stiffening rubber plate 12 One layer of polytetrafluoroethylene slide plate 13 is composed, and the stiffening rubber plate 12 is connected with the bot...

Abstract

The invention relates to a limiting slide plate support seat. The support seat is composed of a top steel assembly, a bottom steel assembly, a PTFE (Polytetrafluoroethylene) rubber slide plate, a steel bar and an anchoring device; the top steel assembly is formed by penetrating a top anchor rod into a top sleeve and a top steel plate and then bolting the top anchor rod with a top anchor bolt; the bottom steel assembly is formed by penetrating a bottom anchor rod into a bottom sleeve and a bottom steel plate and then bolting the bottom anchor rod with a bottom anchor bolt; the PTFE rubber slide plate is formed by adhering one layer of PTFE slide plate to the top of a stiffened rubber plate; and the steel bar and the anchoring device are formed by penetrating the steel bar into a top convex block and a bottom convex block and then anchoring the steel bar via a gasket and a nut. The limiting slide plate support seat related by the invention is clear in principle and simple and convenient in application and can meet a deflection requirement of a bridge in a normal operation stage and limit the overlarge longitudinal displacement of the bridge under the action of an earthquake.

Description

Technical field: [0001] The invention relates to a bridge support, in particular to a position-limiting slide plate support. Background technique: [0002] Skateboard bearings are one of the most common bearing forms used in bridge engineering, and are usually set at the end of continuous girder bridges. The characteristic of the slide bearing is that it can not only provide the vertical support function for the bridge, but also provide a certain longitudinal displacement function for the bridge. Longitudinal displacement is a kind of displacement demand that the bridge structure must adapt to. This is because under the action of temperature, vehicle braking force, etc., the bridge will undergo longitudinal displacement. If the support restricts it, it will cause the internal force of the bridge structure The sharp increase of the bridge affects the normal function of the bridge. [0003] Compared with variable effects such as temperature and vehicle braking force, under o...
