Description
Technical Field
The utility model belongs to bridge beam supports especially indicates a full life ball chamber inversion formula bridge ball shaped steel support.
Background
The support is a key component for bearing a beam body and an abutment in bridge engineering, load and displacement are transmitted to the abutment through the support, so that safety and reliability of a vehicle in operation are guaranteed, and the conventional steel support structure generally adopts a basin-type rubber steel support or a spherical steel support and the like. And because the spherical bearing is provided with no rubber part, the service life influence caused by rubber aging can be avoided, and the spherical bearing with reasonable structure and excellent corrosion prevention method can have the same service life as the bridge in bridge application.
The existing spherical steel support main body is made of carbon steel or cast steel, the spherical crown surface of the spherical cavity lining plate faces downwards, and the rotation of the support is realized through the sliding of the spherical crown surface steel lining plate and the spherical crown surface wear-resisting plate; the requirements of deformation and displacement of the beam body are met by sliding between the wear-resisting plate on the top plane of the ball cavity lining plate and the stainless steel plate of the upper support plate. The rotation angle of the spherical bearing is realized by the sliding rotation of the spherical cavity lining plate, the plane of the spherical cavity lining plate slides correspondingly while rotating, and the plane of the spherical cavity lining plate also bears the plane sliding of the whole bearing to realize the displacement of the bridge, so that the plane wear-resisting plate has large wear resistance, and the service life of the bearing is shortened.
At present, after the displacement and the corner of the spherical bearing with the whole service life are separated, the spherical bearing is subjected to corrosion prevention by adopting a zinc spraying method. However, the lower support plate in the support is of an upright basin type structure or an upright ball cavity structure, and due to the weather conditions, in an air humid environment, condensed water drops on the surface of the spherical crown plate can be slowly accumulated in the concave spherical structure, so that the sliding surface in the rotating structure is influenced. Particularly, the bridge piers of some bridges are short, and the horizontal plane can overflow the pier tops in the flood season, so that the water accumulation phenomenon easily occurs in the basin-type structure or the spherical cavity vertical structure after the bridge support is immersed in water, and the early aging of the support is caused.
The applicant does not find the same patent literature reports as the present application in the domestic patent database.
