Description
Technical field
The present invention relates to the how high-rise steel shaped pile frame of a kind of assembling-prestressing force center support system, belong to technical field of structural engineering.
Background technology
2,000,000,000 square metres of China's annual town and country newly constructed house areas wherein are the high energy consumption building more than 80%, China unit's building area energy consumption is more than 2 times of developed country.Join in a common effort meter according to Chinese steel, China's output of steel was broken through 700,000,000 tons of high pointes in 2011, was sure to occupy output of steel first place, countries in the world in continuous 16 years, and developed country's steel building area accounts for overall floorage more than 50%, and Japan accounts for 80%, and China is less than 4%.China's conduct is the country of construction scope, steel output maximum in the world, and the development of house (comprising dwelling house) steel work seriously lags behind.
At present, the system research to the high-rise steel structure dwelling house both at home and abroad is in the starting stage, and the system innovation of industrialization assembling high-rise steel structure is imperative.Adopted a large amount of welding during the construction of traditional housing building of steel-structure, speed of application is slow, and seriously polluted to environment the most important thing is that the quality of weld seam should not be controlled, and has a strong impact on the security performance of building.
Prestressed cable only is used in the beam string structure at present, does not also use in high-level structure, adopts prestressed cable as high-rise lateral resistant member realization not to be arranged also on engineering.Traditional steel frame structural system, the lateral rigidity of structure is difficult to meet the demands, be out of shape bigger, cause the destruction of non-structural element easily, the how high-rise steel shaped pile frame of assembling-prestressing force center support system, increase horizontal and vertical prestressing force center drag-line on the basis of steel frame and supported, improved the lateral rigidity of structure, improved the deformation performance of structure.
Traditional structure design with analyze, generally beam column node processing in the frame construction is become desirable rigid joint or hinged joint.Because rigid joint bearing capacity and rigidity are all very big, thereby be considered to a kind of ideal shock-resistant node form usually and the node that is widely used in the earthquake zone frame construction connects and designs.But the earthquake experience shows: the rigidity bean column node of building connects and brittle fracture in various degree occurred.Adopt the steel framed structure of welding rigid joint because of node ductility difference brittle fracture to take place easily, and difficulty of construction is also big; Though hinged joint simple structure but rigidity and energy-dissipating property are poor is unfavorable to the antidetonation of structure; Have only the semi-rigid node of connected mode simple and fast to have the two advantage concurrently, have higher strength and stiffness and ductile performance and energy-dissipating property preferably, thereby reduced earthquake to a great extent.

5. the how high-rise steel shaped pile frame of assembling according to claim 1-prestressing force center support system, it is characterized in that: the splicing of assembling column can have bolt hole by hetermorphiscal column frange plate top, the hetermorphiscal column that also has bolt hole with another lower part is spliced column with bolt by scab (10).Scab can be earlier factory with transport to the scene after the hetermorphiscal column bolt is connected and be connected with another pillar bolt again; Also can arrive on-the-spot with bolt column the splicing later; It is convenient that hetermorphiscal column and other cylindricalitys are compared erection bolt.The assembling column also can be by scab (10), and with column welding splicing, scab can be earlier transported to the scene and is welded to connect with another pillar after factory and hetermorphiscal column are welded to connect; Also can arrive on-the-spot later usefulness welding splices column.
6. in the how high-rise steel shaped pile frame of assembling according to claim 1-prestressing force center support system, it is characterized in that: the assembling column is made up of hetermorphiscal column, junction plate (10), hetermorphiscal column has three kinds of forms, non-ly be not: L shaped hetermorphiscal column (7), T shape hetermorphiscal column (8) and cross hetermorphiscal column (9), corresponding bean column node has three kinds of forms, is respectively two to node, three-dimensional node and four-way node; Can be divided into the column of 3 kinds of forms according to the difference of its bean column node, be respectively two-way column, three-dimensional column and four-way column; Two frange plates of L shaped hetermorphiscal column (7) are opened bolt hole form two to the node column; Three frange plates of T shape hetermorphiscal column (8) are opened bolt hole respectively form three-dimensional node column; With cross hetermorphiscal column (9) thus four frange plates open bolt hole respectively and form four-way node column; Respectively with beam on end-plate splice with bolt.The type of attachment of hetermorphiscal column and beam is simple, and hetermorphiscal column is connected with bolt with the beam-ends shrouding, easy construction, and can realize rigidly connecting.
7. in the how high-rise steel shaped pile frame of assembling according to claim 1-prestressing force center support system, it is characterized in that: described floor uses profiled steel sheet combination floor, perhaps reinforced concrete floor, perhaps OSB shaving board.
