Abstract

The invention relates to a universal hinged support with a spring for a building and an installation method thereof. On the basis of the traditional slippage support and the traditional spring support, a radial spherical plain bearing and a belleville spring are added to realize the construction requirement of universal hinging. Meanwhile, the temperature stress of a longspan roof steel structure can be effectively released by the belleville spring, and the seismic response of the longspan roof steel structure is reduced. The universal hinged support with the spring for the building has the advantages of simple structure, high connection precision, wide applicable range and the like, is easy to control, and can be widely applied to the hinged support connection on the building, and is especially suitable for the hinged connection of a roof structure and a lower supporting structure.

Description

Universal hinge support with spring for building and mounting method thereof
Technical field
The present invention relates to a kind of moveable hinge bearing for building and mounting method thereof.
Background technology
Long-Span Steel Space Structures is at home and abroad widely used, and especially in recent decades, has built in the world large-scale gymnasium, terminal, conference centre and the exhibition room etc. of thousands of employing large-span space structure.Long-Span Steel Space Structures is comprised of two class fundamentals: the 1. space structures of bearing load itself; 2. load space structures being born reaches the support node of lower support structure.When the rigidity of flat in-plane stiffness compare great Qie its underpart of Long Span Roof structure supporting construction is also larger, if support node is between the two improper, can in roof structure, produce very large thermal stresses, even can become the governing factor of roof structure and lower support structure design, bring adverse effect to roof structure and supporting construction thereof.Solution to this problem has two kinds: the first is for adopting sliding support release temperature stress, and this support style cannot meet the requirement that support node rotates simultaneously; The second is for adopting spring fastening to reduce thermal stresses.Commonly use at present the form of spring fastening for establish leaf spring in antidetonation ball hinged support casing, by the compound motion of each parts rotation and translation, realize bearing and rotate, by leaf spring, provide bearing elastic stiffness.It is larger that its shortcoming is that casing takies architectural space, and hinged run-on point and the slide plane of in casing, establishing spring carrying block cannot fix on sustained height, and bearing itself exists horizontal shear problem, and bearing itself is stressed unreasonable, affects its application life.
Summary of the invention
The object of this invention is to provide a kind of universal hinge support with spring for building and mounting method thereof, the steel structure node bearing volume that solve existing release temperature stress is large, makes structure itself and has horizontal shear, the problem that application life is short.
For achieving the above object, the present invention adopts following technical scheme:
A kind of universal hinge support with spring for building, comprise base and rotational slip mechanism, described base is comprised of base plate and two support otic placodes, described support otic placode is welded on base plate side by side, described rotational slip mechanism comprises plain radial bearing, connect otic placode and bearing pin, described heart oscillating bearing is enclosed within bearing pin central authorities, and fix by being enclosed within the slippage axle sleeve at bearing pin two ends, described engaging lug sleeve-board is on plain radial bearing, and seal by bearing shrouding, above composite member is through the earhole that supports otic placode, frame supports on otic placode at two, the earhole inwall of described support otic placode scribbles gliding material, and form friction pair between the slippage axle sleeve at bearing pin two ends, described have butterfly spring with cover on the bearing pin of slippage axle sleeve, one end of butterfly spring withstands on to be supported on otic placode, the other end is connected with the end casing that is arranged on slippage axle sleeve outer end.
Described base plate is rectangular steel plates or circular steel plate.
Between described slippage axle sleeve and bearing pin, it is temperature interference fit joint.
Between described slippage axle sleeve and end casing for being threaded.
Described gliding material is copper base sintering graphite or polytetrafluoroethylene (PTFE).
The mounting method of the described universal hinge support with spring for building, step is as follows:
Step 1, makes respectively and connects otic placode, a pair of support otic placode, base plate, butterfly spring, end casing, bearing pin, slippage axle sleeve, bearing shrouding and plain radial bearing according to design size;
Step 2, penetrates bearing pin in plain radial bearing, and makes the central authorities of plain radial bearing in bearing pin;
Step 3, is enclosed within slippage axle sleeve by interference fit joint on the bearing pin of plain radial bearing both sides, fixedly plain radial bearing;
Step 4, by plain radial bearing and bearing pin composite member, penetrates in the hole that connects otic placode, and makes engaging lug sleeve-board on plain radial bearing, then by bearing shrouding, seals;
Step 5, is coated with a circle lubriation material at two hole inwalls that support otic placode, and above composite member is penetrated respectively to two support otic placodes, and by two bottom surface and base plate welding of supporting otic placodes;
Step 6, slippage axle sleeve two ends penetrate successively by the butterfly spring of precompressed and end casing respectively, and by end casing and slip shaft cover screwing.
Step 7, discharges the precompression applying on butterfly spring.
In described step 6, one end of butterfly spring withstands on to be supported on otic placode, and the other end withstands on end casing, and it does not contact completely with slippage axle sleeve.
Compared with prior art the present invention has following characteristics and beneficial effect:
1. this support node can adopt plain radial bearing to meet the structure requirement of universal hinging, adopts butterfly spring can effectively discharge the thermal stresses of Long Span Roof steel work simultaneously, reduces the seismic response of Long Span Roof steel work.
2. by being coated with copper base sintering graphite self-lubricating material in the hole supporting otic placode, the low frictional resistance of having realized between slippage axle sleeve and copper base sintering graphite self-lubricating material slides, and forms friction pair.Due to the existence of friction pair, Long Span Roof steel work is along bearing pin length to sliding.Reduce the horizontal earthquake response of Long Span Roof steel work.
3. by end casing with support between otic placode butterfly spring is set, limited middle Long Span Roof steel work along bearing pin length to slip amplitude, the slip for this direction simultaneously provides certain spring rate, has reduced the stress under temperature action.
4. the present invention is simple in structure, and material source is extensive, and member used is standard component, and the accuracy of manufacture is high, and this support node is owing to can realizing universal hinging, applied widely simultaneously.
The present invention can be widely used in architectural hinged-support and connect, and is particularly useful for being articulated and connected of roof structure and lower support structure.
