Abstract
The utility model belongs to the technical field of a steel supporting seat, which discloses a curve steel supporting seat. The utility model has the main technical characteristics that the curve steel supporting seat comprises an upper cover, a spherical-cap shim plate and a base seat with a spherical-cap-shaped groove, wherein the spherical-cap shim plate is cut with two symmetrical sectional planes, and limited bulges are arranged at both ends of the spherical-cap-shaped groove and the corresponding point of the sectional planes and space certain distance with the sectional planes. The utility model solves the problem that the existing spherical steel supporting seat can not fit the requirement that bending moments are different in each direction in the existing engineering, such as bridge, etc., and can be used for the engineering, such as bridge, etc.
Description
Technical field
The utility model belongs to the steel support technical field, relates in particular to a kind of curved surface steel support.
Background technology
Along with the development of transportation and the raising of construction standard, bearing not only plays a supportive role in bridge and engineering, and should have vibration damping, resistance to plucking, release moment of flexure, resist displacement or the effect of displacement is arranged.The spherical bearing that is used for bridge construction has above advantage and is widely adopted, but, owing to structural reason, this kind bearing all is identical for the moment of flexure on all directions, can not adapt to engineerings such as present bridge at the different needs of all directions moment of flexure.
The utility model content
The purpose of this utility model just provides the requirement of the different moments of flexure of the suitable different directions of a kind of energy, the curved surface steel support with shock resistance.
For achieving the above object, the technical scheme that the utility model curved surface steel support adopts is: comprise loam cake, spherical crown backing plate and have the base of spherical groove, cut two symmetrical cross sections at described spherical crown backing plate, have the restriction protrusion that keeps at a certain distance away with the cross section in the corresponding position in described spherical groove two ends and described cross section.
Its additional technical feature is: described cross section is perpendicular to the plane of spherical crown backing plate; Between described spherical crown backing plate and loam cake, have the plane polyfluortetraethylene plate; Between described spherical crown backing plate and spherical groove, have the polyfluortetraethylene plate that is complementary with spherical crown backing plate bottom surface.
Curved surface steel support provided by the utility model compared with prior art, have the following advantages: one, the spherical crown backing plate is cut two cross sections of symmetry, in the capable restriction protrusion that keeps at a certain distance away with the cross section of the corresponding position in described spherical groove two ends and described cross section band, moving displacement along spherical crown backing plate length direction is big, and along on the short direction of spherical crown backing plate under the restriction of restriction protrusion moving displacement little, adapt to engineering such as present bridge at the different needs of all directions moment of flexure; Its two since the spherical crown backing plate and loam cake and spherical groove between have the sphere polyfluortetraethylene plate, reduced that structure is rotated and the frictional force of displacement.
Description of drawings
Fig. 1 is the structural representation of the utility model curved surface steel support;
Fig. 2 is the schematic diagram of spherical crown backing plate in the utility model curved surface steel support.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model curved surface steel support.
As depicted in figs. 1 and 2, the utility model curved surface steel support comprises loam cake 1, spherical crown backing plate 2 and has the base 4 of spherical groove 3, cuts two symmetrical cross sections 5 at spherical crown backing plate 2, and cross section 5 can be the plane 6 that is diagonal to the spherical crown backing plate.For the needs of designing and constructing, the cross section also can have the restriction protrusion 7 that keeps at a certain distance away with cross section 5 perpendicular to the plane 6 of spherical crown backing plate in the corresponding position in spherical groove 3 two ends and cross section 5.
Structure is rotated and the frictional force of displacement in order to reduce, and has plane polyfluortetraethylene plate 8 between spherical crown backing plate 2 and loam cake; Between spherical crown backing plate 2 and spherical groove 3, have the polyfluortetraethylene plate 9 that is complementary with spherical crown backing plate 2 bottom surfaces.
When using, when external force acted on along spherical crown backing plate 2 length directions, because big along the moving displacement of spherical crown backing plate length direction, moment of flexure was bigger; When external force acts on along the short directions of spherical crown backing plate 2, and along on the spherical crown backing plate 2 short directions under the restriction of restriction protrusion 7 moving displacement little, it is less that moment of flexure is revoked, therefore, this curved surface steel support can adapt to engineering such as present bridge at the different needs of all directions moment of flexure.
Claims (4)
1, curved surface steel support, comprise loam cake, spherical crown backing plate and have the base of spherical groove, it is characterized in that: cut two symmetrical cross sections at described spherical crown backing plate, have the restriction protrusion that keeps at a certain distance away with the cross section in the corresponding position in described spherical groove two ends and described cross section.
