Abstract
The utility model relates to the technical field of bridge support devices, in particular to a spherical steel support. The utility model aims to solve the problems of worse whole reliability and unstable performance in the prior art, and adopts the technical scheme that the spherical steel support comprises an upper support board and a lower support board, and is characterized in that a set of moving elements is arranged between the inner lateral face of the upper support board and the outer end surface of the lower support board, and comprises a stainless steel plate, a side slide board and a rotary bar which are arranged from outside to inside in turn, wherein one side of the longitudinal section of the rotary bar is an arc line, and the lateral face of the rotary bar is a rotary face, the stainless steel plate is fixed on the inner lateral face of the upper support board, and can form a sliding surface with the side slide board arranged on the outer lateral face of the rotary bar, a connecting pin is fixed in the lower support board, and the rotary bar can be movably connected with the connecting pin. Compared with the prior art, the spherical steel support has the advantages of excellent effect and capability of greatly improving performance.
Description
Technical field
The utility model relates to the bracing or strutting arrangement technical field of bridge, is specifically related to a kind of novel ball steel support.
Background technology
Bearing is one of important composition parts in bridge and the construction work, and its effect is that the upper load with bridge and building structure is delivered on the pier by bearing, guarantees the needs of desired stressed, displacement of structure and rotation simultaneously.Spherical steel support because of its have bearing capacity big, rotate flexibly, advantage such as rotating torque is little, allow that corner is big, the Applicable temperature scope is wide, long service life, maintenance work amount are little, thereby by increasing curved, slope, tiltedly and Longspan Bridge institute extensively adopt, become a kind of main seat structure form.
In recent years, along with the increasing of country to the infrastructure construction dynamics, bridge and construction work have obtained high speed development, and all kinds of new structure and functional bridge and building continue to bring out, and also technical performance, function and the cost etc. of bearing are had higher requirement simultaneously.At present, domestic spherical steel support, generally all comprise the upper bracket plate, the spherical crown liner plate, lower support plate, sphere wearing plate, ball face sealing circle, the sphere corrosion resistant plate, the plane wearing plate, planar seal ring, parts such as plane stainless steel plate, wherein on the formed contact surface of the medial surface of upper bracket plate and lower support plate outer face, the sliding function that not only will possess horizontal direction possesses rotating function simultaneously again, owing to rely on the gap to rotate between the two, occur stuck phenomenon easily, directly have influence on the stressed of bridge construction and use; And the selected steel of agent structure such as upper bracket plate, lower support plate and spherical crown liner plate all are cast steel basically, and the material stress level is low, sliding material is the PTFE polyfluortetraethylene plate, long-term use, less stable, therefore the bearing global reliability is relatively poor, unstable properties.
Summary of the invention
The utility model will provide a kind of spherical steel support, to solve the problem of the relatively poor and unstable properties of the global reliability that exists in the prior art.
For effectively overcoming problems of the prior art, technical solution of the present utility model is: a kind of spherical steel support, comprise upper bracket plate and lower support plate, it is characterized in that: be provided with a cover action component between described upper bracket plate medial surface and the lower support plate outer face, described action component comprises corrosion resistant plate, side skid and the rotation strip that ecto-entad sets gradually, one side of rotation strip longitudinal cross-section is a camber line, and this side is a plane of rotation; Described corrosion resistant plate is fixedly set in upper bracket plate medial surface, forms slide plane with the side skid that is arranged on the rotation strip lateral surface; Be set with connecting pin in the lower support plate, rotation strip is connected with connecting pin is movable.
The material of above-mentioned side skid is the SF-I three-layer composite board.
Above-mentioned connecting pin and the riveted joint of lower support plate tight fit and the riveted joint of rotation strip gap.
Compared with prior art, performance of the present utility model is greatly enhanced: in the action component of increase, rotation strip is crucial, two side is realized two kinds of holding functions respectively, one is plane of rotation, and one is slide plane, makes the plane of rotation of bearing and slide plane realize the separate type design, so just stuck situation be can not occur again, thereby slip, rotation and the holistic resistant behavior of bearing promoted.
Description of drawings
Fig. 1 is the structural representation of the spherical steel support of the utility model;
Fig. 2 is the utility model rotation strip project organization enlarged drawing;
Description of reference numerals is as follows:
1-upper bracket plate, 2-lower support plate, 3-connecting pin, 4-rotation strip, 5-side skid, 6-corrosion resistant plate.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
A kind of spherical steel support comprises upper bracket plate 1 and lower support plate 2, is provided with a cover action component between said upper bracket plate 1 medial surface and lower support plate 2 outer faces.Said action component comprises corrosion resistant plate 6, side skid 5 and the rotation strip 4 that ecto-entad sets gradually, and the material of side skid 5 is the SF-I three-layer composite board, and a side of rotation strip 4 longitudinal cross-sections is a camber line, and this side is a plane of rotation; Said corrosion resistant plate 6 is fixedly set in upper bracket plate 1 medial surface, forms slide plane with the side skid 5 that is arranged on rotation strip 4 lateral surfaces; Be set with connecting pin 3 by tight fit riveted joint mode in the lower support plate 2, rotation strip 4 is realized movable the connection with connecting pin 3 in gap riveted joint mode, and rotation strip 4 realizes that with the outer face of lower support plate 2 x wire contacts.
During use, when bearing rotated, the circular arc of plane of rotation contacted design with the plane cooperation, makes that rotation is more flexible; Simultaneously, the lateral sliding face will remain face contact, and will be stressed evenly to guarantee slide surface, thereby resistance to displacement and stress when significantly having reduced support displacement are concentrated the gliding material wearing and tearing that cause, and effectively promote the holistic resistant behavior of bearing.
