Description
Technical field
The utility model relates to bridge construction technology, particularly the flat hinge of a kind of sphere.
Background technology
In the bridge construction process that China is current, the use of construction by swing gets more and more, mainly because the construction equipment of construction by swing requirement is few, easy and simple to handle.And along with the synchronous jack of advanced person and the use of computer autocontrol technique, construction by swing has progressively been applied on large span, large heavy girder.Such as: the husky bridge (main bridge is the three stride continuous self-anchoring type concrete-filled steel tubes arch bridge of 76m+360m+76m) of Guangzhou bifurcation hair worn in a bun or coil, be the swivel bridges of flat turn after first vertical transfer, flat turn weight reaches 13600 tons; Seek the single pylon cable stayed bridge that Railway Cable-stayed Bridge is the 40.75m+50m span layout of flat turn method construction in expanding on Dalian-Qinhuangdao Railway is large, weight of turning is 3400 tons; Shuibai Railway north, Guizhou Province dish Jiang great Qiao is the Deck Arch Bridges that main span reaches 236m, and weight of turning is 10400 tons.
At the bottom of pier during rotator construction, the adjustment superstructure position after-pouring pier base concrete that puts in place of turning, if pier height is higher, weight of turning will be very large.At present, conventional design scheme has: at the bottom of pier to ball pivot and relevant ancillary facility of turning are installed between cushion cap, to put in place wait turning and after the accurate adjustment of superstructure position, concreting make bridge pier and cushion cap affixed.But owing to being subject to the impact of ball pivot size and traffic condition, turn tonnage mostly below 30,000 tons, super-tonnage is turned and is positioned at weight of turning at 3 ~ 100,000 tons.When weight of turning is larger, the diameter of Rotary ball hinge also needs comparatively large, but the monoblock cast difficulty of processing of ball pivot is very large, and often can be subject to the restriction of whole Transporting condition.
As from the foregoing, in current construction by swing, although adopt cast steel ball hinged advantage more, more difficult and limited due to size of its ball pivot processing, therefore weight of turning also will be restricted.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the utility model is further described.
Present embodiments provide the flat hinge of a kind of sphere, thus the rotator construction requirement of weight very large (such as, 3 ~ 100,000 tons of weight of turning) of turning can be met, and the convenient manufacturing, form of construction work is also more flexible.
Fig. 1 is the structural representation that sphere in the utility model embodiment equals hinge, and Fig. 2 is the elevational schematic view that sphere in the utility model embodiment equals hinge.As depicted in figs. 1 and 2, the sphere in the utility model embodiment is equalled hinge and is mainly comprised: above flat hinge 11, lower flat hinge 12 and bearing pin 12;
The soffit of the steel plate of described flat hinge 11 is convex spherical; The upper surface of the steel plate of described lower flat hinge 12 is concave spherical surface;
The concave spherical surface of described lower flat hinge 12 is provided with groove, in described groove, is laid with slide plate (not shown);
The center of described flat hinge 11 and lower flat hinge 12 offers circular hole and is provided with sleeve 14, described flat hinge 11 is arranged on described lower flat hinge 12, described flat hinge 11 and lower flat hinge 12 are by being connected with the bearing pin 13 of sleeve 14 with the circular hole in lower flat hinge 12 through described flat hinge 11, and the bottom of described bearing pin 13 is embedded in concrete before turning.
Preferably, in specific embodiment of the utility model, described slide plate is MG or ultra-high molecular weight polyethylene slide plate or modified Teflon slide plate.
Preferably, in specific embodiment of the utility model, the described upper plane of flat hinge 11 and the lower plane of lower flat hinge 12 are provided with WELDING STUDS 15, thus effectively can strengthen upper flat hinge and lower flat hinge is bonding with concrete, strengthen the globality of flat hinge of turning.
Preferably, in specific embodiment of the utility model, described flat hinge 11 and lower flat hinge 12 all can use steel plate or cast steel directly to process.
Preferably, in specific embodiment of the utility model, described flat hinge 11 and lower flat hinge 12 all can be formed by plane steel plate machine manufacture.
In addition, in the technical solution of the utility model, described flat hinge 11 and lower flat hinge 12 all form by entirety manufacture, also can piecemeal manufacture.
Such as, when the average weight of turning or less time, sphere equals the upper flat hinge of hinge and lower flat hinge all can use steel plate directly to process rear whole Transporting, to facilitate the manufacturing.And when the tonnage of turning is larger, upper flat hinge and lower flat hinge piecemeal (being divided into plane projection to be fan-shaped or semicircle) at need, then can manufacture, reserved scab and bolt hole by whole Transporting, position, conservative control hole and bolt hole size, be spliced into entirety after being transported to scene again.
In addition, consider the problem of sphere difficulty of processing and the restriction of whole Transporting condition, the flat hinge after unit is transported to scene of the sphere of piecemeal manufacture assembles distortion for preventing, and the method that bolt can be adopted to splice connects, thus effectively can control the assembling distortion that sphere equals hinge.
Such as, as shown in Figure 3, preferably, in specific embodiment of the utility model, described flat hinge 11 is spliced by multiple flat hinge unit 110, and each is connected and fixed by scab and bolt 111 between flat hinge unit 110.Such as, as shown in Figure 3, described flat hinge 11 is spliced by 2 upper flat hinge unit 110, is connected and fixed between 2 upper flat hinge unit 110 by scab and bolt 111.
Preferably, in specific embodiment of the utility model, the plane projection of described flat hinge unit is fan-shaped or semicircle.
Preferably, in specific embodiment of the utility model, the edge of described flat hinge unit is provided with scab, described scab is provided with bolt hole.Therefore, can by through being bolted to together on described scab between two adjacent upper flat hinge unit.
In like manner, preferably, in specific embodiment of the utility model, described lower flat hinge is formed by multiple lower flat hinge unit spliced, is bolted between each lower flat hinge unit.
Preferably, in specific embodiment of the utility model, the plane projection of described lower flat hinge unit is fan-shaped or semicircle.
