The portal frame beam-column comprises a vertical column 2 and a crossbeam 1 arranged on the vertical column 2, a first included angle Alpha is formed at a link joint of the vertical column 2 and the crossbeam 1, the utility model is characterized in that a curved hunched slab 3, consisting of a curved sheet 3' and a rectangular sheet 3'', is arranged at a portal frame beam-column link joint. The plane of the curved sheet 3' is vertical to the plane of the rectangular sheet 3'',and the geometrical extension lines of the two edges AC, BD of the curved sheet 3' are intersected at a point O; the geometrical extension lines of a first edge AC and a second edge BD form a second included angle AOB, the angle of the first included angle Alpha is equal to the second included angle AOB; and the two edges AC and BD are respectively arranged on the crossbeam 1 and the vertical column 2.
Description
Technical field
The utility model relates to the connection of general building structure, specifically is concrete column and being connected of beam.
Background technology
Portal frame structure is fast because of its speed of application in the steel work, and cost is not high, and a large amount of is used.Portal-rigid frames beam-column connection position stress is concentrated and is bigger, so the engineering accident that the position causes is many, particularly at end plate and bolted node, especially haunch node, the integral rigidity height of some node, but material usage is big, and construction is complicated, be connected to together monolithic node as beam column with weld seam and nodes domains, its mechanical property is reliable relatively; Some node type simple structure, easy construction, also save material, but its mechanical property is unsatisfactory, for example common its integral rigidity of beam-column connection is little, and the load action down cut is in a disguised form big, and big shear strain meeting causes in the girder span amount of deflection very big, make the member integral rigidity poor, it can only be applicable to the situation that internal force is little.
Summary of the invention
The purpose of this utility model is to improve the mechanical characteristic of portal-rigid frames beam-column connection, improves the rigidity of node.
The utility model is a kind of portal-rigid frames beam-column connection structure, the portal-rigid frames beam column comprises column 2 and the crossbeam 1 that is installed on the column 2, column 2 becomes the first angle α with crossbeam 1 at the connected node place, at the portal-rigid frames beam-column connection arc haunched slab 3 is installed, arc haunched slab 3 is by an arc 3 ' and a rectangular slab 3 " form; the plane of arc 3 ' is perpendicular to rectangular slab 3 " the plane, 3 ' two ends of arc limit AC, how much extension lines of BD intersect at an O, the first end limit AC becomes the second angle ∠ AOB with how much extension lines of the second end limit BD, the angle of the first angle α equals the angle of the second angle ∠ AOB, two end limit AC of arc 3 ', BD is installed in respectively on crossbeam 1 and the column 2.
The beneficial effects of the utility model are: (1) this node is compared with common bean column node, has good stress performance, and the arc haunched slab has further guaranteed the globality of node, and the rigidity of node is bigger.(2) compare with conventional haunch, this haunch is the arc haunch, is convenient to the connection of Bolted End-plate first, second makes the stressed smoothness of structural element, and haunch has constituted defence line, second road simultaneously, prevents the generation of load action lower member brittle fracture.(3) by the effect of arc haunched slab, alleviated the stress concentration degree in load action lower node territory, nodes domains there is the better protect effect.Satisfy the design principles of the weak rod member of the central strong node of engineering design.(4) node adopts the form that the bolt weldering connects, and the weld strength that neutralized is big, and Bolted End-plate connects the good advantage of ductility, and it is big also to have solved rigidity, the contradiction of court of a feudal ruler property difference.Thereby further improved bearing of component, and its simple structure, if during construction on the beam column connecting portion welds again haunch arc plate, construction is easy to the building-site installation easily.(5) haunch arc plate and beam column connecting portion contact area are big, thereby reduced the possibility of concentrating the beam column edge of a wing yield failure that causes because of stressed, haunch arc plate is that strong that the beam column Bolted End-plate connects replenishes simultaneously, can better make the beam column co-ordination, and the effect of will carrying outward is delivered to substructure.
Description of drawings
Fig. 1 is a structure chart of the present utility model, and Fig. 2 is the lateral view of arc haunched slab, and Fig. 3 is the vertical view of arc haunched slab.
The specific embodiment
As shown in Figure 1, the portal-rigid frames beam column comprises column 2 and the crossbeam 1 that is installed on the column 2, and column 2 becomes the first angle α with crossbeam 1 at the connected node place, at the portal-rigid frames beam-column connection arc haunched slab 3 is installed.As Fig. 2, shown in Figure 3, arc haunched slab 3 is by an arc 3 ' and a rectangular slab 3 " form; arc 3 ' the plane perpendicular to rectangular slab 3 " the plane, how much extension lines of 3 ' two ends of arc limit AC, BD intersect at an O, the first end limit AC becomes the second angle ∠ AOB with how much extension lines of the second end limit BD, and the angle of the first angle α equals the angle of the second angle ∠ AOB.As shown in Figure 1, two of arc 3 ' ends limit AC, BD are installed in respectively on crossbeam 1 and the column 2.Arc 3 ' two the end limit AC, BD be welded on respectively on crossbeam 1 and the column 2.
As Fig. 2, shown in Figure 3, arc haunched slab 3 is by an arc 3 ' and a rectangular slab 3 " form, adopt two block plates to be welded.Be the stability inside and outside the plane that increases the arc haunched slab, haunched slab adopts two plates vertically to place, for the ease of the convenience that beam column is installed, the hole of having opened circular arc on haunched slab.Weld together between haunched slab and the portal-rigid frames beam column, improve the node rigidity of member, ductility is also fine, avoid the brittle fracture of incidental load effect lower member, can allow a part of moment of flexure and shearing directly pass on the post by haunch simultaneously, alleviated excessive moment of flexure and shearing action, improved bearing of component nodes domains.
