Embodiment 1

[0022] Please refer to Fig. 1, according to the known common sense, the lower support plate 2 is fixed with the pier 20 (shown in Fig. 2) of the bridge, specifically: the number of the lower support plate 2 is not limited by the first The fixing member hole 122 is inserted into the first fixing member hole 22 by a group of first fixing members 23 and fixed with the embedded parts on the pier 20 . The specific shape of the lower support plate 2 is not limited by the illustration, and the central area of ​​the side of the lower support plate 2 facing the upper support plate 1, that is, the upper side of the lower support plate 2 in the state shown in the present illustration The central region forms a ring-shaped first edge 21, and a spherical concave cavity 211 is formed in the first edge 21, and the spherical concave cavity 211 is arranged, that is, the paving shape is basin-shaped and is preferably made of polytetrafluoroethylene material. The third anti-friction plate 6 form...

Abstract

The invention relates to a turnable spherical support belonging to the bridge facility technology field, which comprises an upper support plate, a lower support plate, a first wear-resisting plate, a buffer plate, a second wear-resisting plate, a spherical support body, a third wear-resisting plate and a bridge beam body fixing plate; which is characterized in: a first central shaft hole is formed in the center of the cavity of the upper support plate; a second central shaft hole is formed in the center of the first wear-resisting plate; a third central shaft hole is formed in the center of bridge beam body fixing plate; the three central shaft holes are coincided with each other; and a central shaft is disposed with its lower end fixed with the first central shaft hole and its upper end extended into the third central shaft hole. Advantages: when a bridge beam body is placed on the bridge beam body fixing plate and dragged, the spherical support can not only support the bridge beam body, but also ensures the bridge beam turnable, thereby can ensure the safety and no traffic interruption of the trunk road under the bridge beam body in the pavement process.

Description

technical field [0001] The invention belongs to the technical field of bridge facilities, and in particular relates to a swivel spherical bearing. Background technique [0002] As known in the industry, bridge bearings are structurally divided into basin-shaped bearings and spherical bearings, which are installed between the bridge pier and the bridge girder body. Vibration. Figure 2 shows a widely used spherical bearing in the prior art, which includes upper and lower bearing plates 1, 2, the first anti-friction plate 3, buffer plate 4, the second anti-friction plate 8, a spherical support 5. The third anti-friction plate 6 and the bridge girder body fixing plate 7 form a first pier 21 in the middle area of ​​the side of the lower support 2 facing the upper support plate 1 for fixing with the pier of the bridge , a spherical concave cavity 211 is formed in the first stack edge 21, the third anti-friction plate 6 is placed in the spherical concave cavity 211, the spherical...
