Abstract
The utility model relates to a saddle-shaped cable net restraint support structure, which comprises a central support component, lug plates, an oblique prestress pull cable and an annular prestress pull cable. The lug plates are welded at the upper end and the lower end of the support component, the oblique prestress pull cable is connected to the upper lug plate and the lower lug plate which are non-coplanar on the support component via anchoring nodes to form a space hyperbolic paraboloid, the annular prestress pull cable is constructed in the middle portion of the space hyperbolic paraboloid, thereby forming the saddle-shaped cable net restraint support structure. The structure has the advantages of forming space restraining and improving capability of energy absorption and dissipation of the structure by sufficiently using strong tensile property of the pull cables, having excellent architectural art effect, avoiding onsite welding during construction to shorten construction period and lower construction cost, being applicable in support components of various frame structures, in particular to outdoor wide-span oblique support structures, and realizing perfect integration of architectural attractiveness and reasonable structure.
Description
Technical field
The utility model relates to the novel buckling-resistant support structure in a kind of building structure, more particularly, a kind of saddle shaped rope net of being made up of center support member, otic placode, oblique prestressed cable and ring orientation prestress drag-line that relates in a kind of building structure retrains braced structures.
Background technology
Frame construction has been widely used in highrise building and the long span building structure now, can make frame construction possess higher lateral deformation stiffness and support, and is the main member of frame construction in seismic design.Traditional band support frame has center support framework and eccentric support frame,, and support meeting pressurized flexing when middle shake and macroseism in the traditional center support framework and tension surrender, and the pressurized flexing is unfavorable for energy-dissipating and shock-absorbing.The method of present existing solution pressurized flexing is the external steel sleeve of the core of outer centre of support, fills by some buildings then, and anti-like this flexing supports and exists with next aspect deficiency:
(1) external steel pipe increases the steel using amount of structure collectivity; Make the structure outward appearance seem the comparison heaviness, influence the appearance and modeling of steel work integral body;
(2) external steel pipe, middle working procedure complexity of filling constructional materials, the construction convenience is poor; Tradition
(3) in the severe earthquake action process, if produce distortion improperly, external steel pipe might be strengthened braced structures, can't consume energy, and makes seismic load directly destroy main frame structure.Therefore the anti-flexing of this external steel pipe supports and has certain potential safety hazard.
(4) the anti-flexing supporting damping of external steel pipe is than difficult control in design and construction, and damping ratio will cause certain potential safety hazard to structure improperly.
The utility model content
In order to overcome deficiency of the prior art, the utility model provides a kind of saddle shaped rope net constraint braced structures, it is assemblied to form at the scene by the center support member of prefabricated band otic placode, oblique prestressed cable and ring orientation prestress drag-line, working procedure is clear and definite, technology is simple, avoid field Welding, reduced construction period, saved construction cost; By the application of prestressing technique, realized the slim and graceful art of building effect attractive in appearance of steel work; Simultaneously, this structure stress is clear, and Energy Dissipation Mechanism is clear and definite, by the damping ratio of the prestressed size adjustment structure of drag-line, makes this structure design according to fully, has avoided some potential safety hazards, can satisfy anti-flexing and support the various requirement that is provided with.
The technical solution of the utility model is as follows:
A kind of saddle shaped rope net constraint braced structures, comprise center support member, otic placode, oblique prestressed cable, ring orientation prestress drag-line, it is characterized in that: described otic placode is fixedly connected on center support member two ends, described otic placode has 16, eight at every end, be welded on the end of center support member equably, adjacent two otic placode angles are 45 °; Oblique prestressed cable and center support member the two ends not otic placode of coplane link to each other.
The plane included angle, two otic placode places that described oblique prestressed cable links to each other with center support member two ends is 135 °.
Described oblique prestressed cable is shaped on anchorage node in advance, is connected with otic placode by bolt.
Described oblique prestressed cable and ring orientation prestress drag-line are provided with the prefabricated blue bolt of spending, and by flower basket bolt drag-line are applied prestressing force.
A kind of preparation method of saddle shaped rope net constraint braced structures, it is characterized in that: weld prefabricated center support member and otic placode in factory, then oblique prestressed cable is connected by bolt with otic placode, oblique prestressed cable is applied first step prestressing force by the blue bolt of spending of self, at last the ring orientation prestress drag-line is curled the hyperbolic paraboloid centre position of forming at oblique prestressed cable, space, the blue bolt of spending by ring orientation prestress drag-line self applies prestressing force to the ring orientation prestress drag-line, also oblique prestressed cable is applied the second step prestressing force simultaneously.
The beneficial effects of the utility model are the problems that solve the big and aesthetics difference of existing buckling-resistant support structure steel using amount, have eliminated buckling-resistant support structure potential safety hazard in use.Element of construction can be realized batch production production, has simplified working procedure, has shortened construction period, has reduced construction cost.Be applicable to the braced structures of various frame constructions, especially expose, realize the perfect unity that building is attractive in appearance and rational in infrastructure in the oblique braced structures of outdoor large span.
