Horizontally rotate hinged-support
Technical field
The present invention relates to building structure node hinged-support, specifically a kind of hinged-support that horizontally rotates.
Background technology
Gallery, overline bridge, as the interface channel between building, widely adopt in modern building design, by such connection design, make the people-to-people contacts in building convenient.But because gallery, overline bridge span are generally larger; when meeting the disaster scenarios it such as earthquake, storm; gallery or overline bridge usually there will be the phenomenons such as two ends are reversed, pullled, upper and lower sedimentation, cause gallery, overline bridge to destroy, and cannot guarantee the safety of gallery in earthquake and normal use.
Current in gallery earthquake research field, seeking more effective antidetonation means, to resist earthquake significant to gallery structural damage.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of hinged-support that horizontally rotates is provided, adopt this hinged-support effectively to guarantee earthquake the safe, not fragile of district and typhoon prone areas gallery, overline bridge that take place frequently.
According to technical scheme of the present invention: a kind of hinged-support that horizontally rotates, it is characterized in that: comprise pre-embedded steel slab, described pre-embedded steel slab upper surface laminating arranges a stainless steel clad plate, and between described pre-embedded steel slab and stainless steel clad plate, by resistance to plucking crab-bolt, be fastenedly connected, resistance to plucking crab-bolt lower end is stretched out pre-embedded steel slab bottom surface and is extended a segment distance; Pier stud outer cover is fixedly installed on stainless steel clad plate upper center, and pier stud rotates and is arranged in described pier stud outer cover, and in pier stud kerve, is provided with circular polyfluortetraethylene plate, and described polyfluortetraethylene plate bottom surface fits on stainless steel clad plate upper surface; Upper junction plate assembly is arranged in pier stud upper surface ear groove, described upper junction plate assembly comprises upper junction plate, axis of rotation, wherein upper junction plate comprises the panel part that is placed in pier stud Er Caonei support sector and is connected in described support sector upper end, and axis of rotation runs through described support sector.
As a further improvement on the present invention, described pier stud upper end has the closing in of infolding, and the shoulder portion of pier stud outer circumference surface is resisted against described closing in lower end.
As a further improvement on the present invention, described pier stud outer cover is welded in stainless steel clad plate upper surface.
As a further improvement on the present invention, described rotating shaft terminal is fixed on pier stud by hexagon socket head cap screw and axis of rotation block.
Technique effect of the present invention is: the present invention is as the rotary middle point of gallery, overline bridge, along either direction horizontal shear force, be 2704kN, to upper support vestibule bearing capacity 3000kN, stablize vestibule bearing capacity 3516kN downwards, its distributing position is along on gallery direction center line, and be positioned at fixed point rotary end, and horizontally rotate the complete vestibule two ends that are used in of hinged-support, guaranteed the safety of vestibule in high wind shake and earthquake.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ 3, comprise stainless steel clad plate 1, pre-embedded steel slab 2, polyfluortetraethylene plate 3, pier stud outer cover 4, pier stud 5, axis of rotation 6, upper junction plate 7, the 7-1 of support sector, panel part 7-2, axis of rotation block 8, hexagon socket head cap screw 9, resistance to plucking crab-bolt 10 etc.
As shown in Fig. 1 ~ 3, the present invention is a kind of hinged-support that horizontally rotates, comprise pre-embedded steel slab 2, described pre-embedded steel slab 2 upper surface laminatings arrange a stainless steel clad plate 1, and between described pre-embedded steel slab 2 and stainless steel clad plate 1, by resistance to plucking crab-bolt 10, be fastenedly connected, resistance to plucking crab-bolt 10 lower ends are stretched out pre-embedded steel slab 2 bottom surfaces and are extended a segment distance; Pier stud outer cover 4 is fixedly installed on stainless steel clad plate 1 upper center, and pier stud 5 rotates and is arranged in described pier stud outer cover 4, and is provided with circular polyfluortetraethylene plate 3 in pier stud 5 kerves, and described polyfluortetraethylene plate 3 bottom surfaces fit on stainless steel clad plate 1 upper surface; Upper junction plate assembly is arranged in pier stud 5 upper surface ear grooves, described upper junction plate assembly comprises upper junction plate 7, axis of rotation 6, wherein upper junction plate 7 comprises the panel part 7-2 that is placed in pier stud 5 7-1 of Er Caonei support sector and is connected in the described 7-1 of support sector upper end, and axis of rotation 6 runs through the described 7-1 of support sector.
Described pier stud 5 upper ends have the closing in of infolding, and the shoulder portion of pier stud 5 outer circumference surfaces is resisted against described closing in lower end.
Described pier stud outer cover 4 is welded in stainless steel clad plate 1 upper surface.
Described axis of rotation 6 two ends are fixed on pier stud 5 by hexagon socket head cap screw 9 and axis of rotation block 8.
The course of work of the present invention is as follows: according to field condition, build fastener inserts (the interior part of dotted line frame in Fig. 1), concrete casting is to flushing with pre-embedded steel slab 2.Treat concrete setting and meet maintenance after date, stainless steel clad plate 1 is installed and is connected by resistance to plucking crab-bolt 10 with pre-embedded steel slab 2.After polyfluortetraethylene plate 3 embeds pier stud 5 kerves, be put in stainless steel clad plate 1 surface, and put pier stud outer cover 4, adjust pier stud 5 behind the desired position of stainless steel clad plate 1, pier stud outer cover 4 carries out periphery weld all around with stainless steel clad plate 1.Upper junction plate assembly is put into pier stud 5 ear grooves, by axis of rotation 6, run through upper junction plate assembly and pier stud 5.Axis of rotation 6 two ends are anchored on axis of rotation block 8 on pier stud 5 with hexagon socket head cap screw 9.
This hinged-support at the construction field (site) fixedly composite stainless steel plate 1 realize pressing with pier stud 5 bearing loads of inlaid polytetrafluoroethylsliders plate 3 and cut sliding function, pier stud 5 by inner circular polyfluortetraethylene plate 3 can level to rotating freely, upper junction plate 7 is connected and can in claimed range, swings up and down with gallery bottom.Owing to having adopted polyfluortetraethylene plate 3 can bear the bearing pressure of 25MPa, and under earthquake and wind earthquake situations condition, bear long-term pressure mill with stainless steel clad plate 1 surface.
The present invention horizontally rotates the difficult problem that hinged-support efficiently solves middle high-intensity earthquake area, stands for a long time the design of building structures such as typhoon region.
Horizontally rotating hinged-support is hinged plank support, realizes horizontal direction 360 degree rotary shifted by the planar slide between polyfluortetraethylene plate 3 and stainless steel clad plate 1, has anti-pulling, spacing, longitudinal rollover characteristics.
