Abstract

The utility model discloses a beam column nodal point suitable for a square steel pipe column; the beam column nodal point comprises an under layer square steel pipe column and an upper layer square steel pipe column, wherein a dog bone type short joist steel cantilever is arranged on the under layer square steel pipe column; the end part of the under layer square steel pipe column is connected with a lower flange; the end part of the upper layer square steel pipe column is connected with an upper flange which is matched with the lower flange; an interpolated section with a transverse stiffening rib is arranged on the lower flange and is matched with an inner hole of the upper layer square steel pipe column; the upper layer square steel pipe column is sheathed on the interpolated section; and the lower flange and the upper flange are tightened and connected by a bolt. The beam column nodal point effectively realizes the external shift of the plastic angle of a nodal point domain, improves the performance of a second earthquake of the nodal point domain and simplifies the construction technology of a beam column connection of a steel frame.

Description

Be applicable to the bean column node of quadrate steel pipe column
Technical field
The utility model 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, relates 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 the utility model similar techniques.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.
The utility model content
The purpose of this utility model provides 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.
The technical solution of the utility model:
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 of band transverse stiffener, is connected by bolt tightening between described lower flange and the upper flange.
The beneficial effects of the utility model: realize that by the short i iron 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, the outer side contacts of the inboard interpolation section of post with the band transverse stiffener, the interpolation section of band transverse stiffener 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.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is axle survey views such as southwest of the present utility model;
Fig. 2 is front of the present utility model and vertical view, and wherein Fig. 2 a is a front view, and Fig. 2 b is a vertical view;
