Description
Technical field
The present invention relates to a kind of building connector, relate to a kind of steel structure frame connected node specifically.
Background technology
In construction steel frame, the steel structure connection characteristic between crossbeam and mullion is the key of structural-load-carrying capacity and shock resistance.Traditional steel structure node connects generally takes welding or welding and bolt in conjunction with connected mode, and its shortcoming easily causes stress to concentrate or installs inconvenience, and be unfavorable for that standardized production is less economical.
The applicant was in 2007, apply for a kind of " Connection Card and construction steel frame node structure ", in 2009, applied for a kind of " Connection Card and use the construction steel frame node structure of this Connection Card ", its weak point is: a node structure needs four pairs of fasteners of eight fasteners compositions completing the connection of whole node.Wherein connect the frange plate up and down of the girder steel in direction, opposite two by each a pair fastener up and down, perpendicular to girder steel crossing direction then need by addition up and down each a pair fastener complete the connection of the frange plate up and down of crossing girder steel.Need two to intersect the top flange of direction girder steel in the plane of sustained height in the application, therefore the fastener in a direction just can only be put, and fastening the snapping into of another vertical direction is put, and causes node transmission force property in both intersecting directions different; In same plane, positive and negative installation two pairs of fasteners are not only made troubles to installation in addition, are also unfavorable for saving material.The applicant submits in December, 2014 and accepts, apply for a kind of " annular self-locking node connecting structure " (201410801851.6), solve the connection that simultaneously can complete on two crossing directions, and the connection solving girder steel on two crossing directions is with high problem.But these two kinds of nodes all need by installing the shear resistance that node just can be made to reach ideal performance or fully realize this node structure such as facility or special tool, as in 201410801851.6 Fig. 5 F place applies after larger pulling force while fastening pretension bolt (43) this node structure can be made fully to realize larger shear resistance.If there is a kind of node structure, can possess assembly structure have possess better shearing resistance and anti-bending strength simultaneously again can not by special-purpose machines and tools, installation can be completed simply by the method for lock bolt, will the installation of great quantity of small building frame construction be applicable to, as little structural steel frame classification villa structure.
Summary of the invention
