Abstract
The invention discloses a beam column node suitable for a quadrate steel pipe column, which comprises a lower quadrate steel pipe column and an upper quadrate steel pipe column. A dog bone type short I-shaped steel cantilever is arranged on the lower quadrate steel pipe column; a lower flange is connected with the end part of the lower quadrate steel pipe column; an upper flange matched with the lower flange is connected with the end part of the upper quadrate steel pipe column; an inner insertion section with a transverse stiffening rib, matched with an inner hole of the upper quadrate steel pipe section, is arranged on the lower flange; the upper quadrate steel pipe column is sleeved on the inner insertion section; and the lower flange and the upper flange are fastened and connected via a bolt. The beam column node for the quadrate steel pipe column effectively realizes the outward movement of a node region plastic corner, improves the secondary shock resistance of the node region, and simplifies the construction process of the steel frame beam column connection.
Description
Technical field
The invention belongs to the design and the construction method technical field of the node of quadrate steel pipe column and steel I-beam in the field of civil engineering steel framed structure, relate in particular to a kind of bean column node that is applicable to quadrate steel pipe column.
Background technology
In the steel framed structure, the connected mode of quadrate steel pipe column and steel I-beam comprises that post is through, beam is through and dividing plate is through, and at present domestic also do not have and similar techniques of the present invention.In recent years, the requirement of structural seismic and day sharp increase." the weak rod member of strong node " is the effective means that improves the whole anti-seismic performance of frame construction, but is difficult to realize this requirement in reality design and the work progress.Tracing it to its cause, mainly is that node region easily forms plastic hinge, and structure is in secondary, phenomenon such as basic forfeiture shock resistance under the earthquake repeatedly.
Summary of the invention
The purpose of this invention is to provide a kind of bean column node that is applicable to quadrate steel pipe column that can improve node ductility and can improve structure secondary shock resistance and security performance.
Technical scheme of the present invention:
A kind of bean column node that is applicable to quadrate steel pipe column, comprise: lower floor's quadrate steel pipe column and upper strata quadrate steel pipe column, on lower floor's quadrate steel pipe column, be provided with the short i iron cantilever of dog bone type, end at lower floor's quadrate steel pipe column is connected with lower flange, be connected with the upper flange that can be complementary with lower flange in the end of upper strata quadrate steel pipe column, on lower flange, be provided with the interpolation section of the band transverse stiffener that the endoporus with the upper strata quadrate steel pipe column is complementary, and the upper strata quadrate steel pipe column is enclosed within on the interpolation section, is connected by bolt tightening between described lower flange and the upper flange.
Beneficial effect of the present invention: realize that by the short cantilever of dog bone type the nodes domains plastic hinge moves, and improves node ductility outward; When flange bolt after losing bearing capacity under the severe earthquake action, the upper strata quadrate steel pipe column is subjected to displacement, post inboard with the outer side contacts of interpolation section, the interpolation section provides drag to guarantee structural safety, has improved structure secondary shock resistance; Simplify the site construction technology that beam column connects, conventional construction method reduces the field Welding workload significantly relatively, improves efficiency of construction.

The specific embodiment
A kind of bean column node that is applicable to quadrate steel pipe column, comprise: lower floor's quadrate steel pipe column 1 and upper strata quadrate steel pipe column 5, on lower floor's quadrate steel pipe column 1, be provided with the short i iron cantilever 4 of dog bone type, be connected with lower flange 2 in the end of lower floor's quadrate steel pipe column 1, be connected with the upper flange 6 that can be complementary with lower flange 2 in the end of upper strata quadrate steel pipe column 5, on lower flange 2, be provided with the interpolation section 3 of the band transverse stiffener that the endoporus with upper strata quadrate steel pipe column 5 is complementary, and upper strata quadrate steel pipe column 5 is enclosed within on the interpolation section 3, is connected by bolt tightening between described lower flange 2 and the upper flange 6.Between described interpolation section lateral surface and the quadrate steel pipe column medial surface 2～3mm gap is arranged.
Behind square steel pipe frame column 5 hoisted in position of upper strata, with the present invention by temporary fixed after 3 sockets of node interpolation section, adopt bolts to be connected the lower flange 2 of the upper flange 6 of upper strata quadrate steel pipe column 5 ends and lower floor quadrate steel pipe column 1, the rigidly connecting of implementation framework post and node.Then, i iron Vierendeel girder lifting is put in place, steel I-beam is temporary fixed with two plates and bolt earlier with short cantilever of the present invention 4, and it is stubborn that end carried out to bolt in the fine setting back, lacks the last bottom flange of cantilever 4 and steel I-beam simultaneously and all adopt the mode of welding to be connected.Thereby realize that beam column of the present invention connects new technology.
