Arrangement, it is therefore intended that first erecting and welding combined special-shaped column upper cantilever beam section lower flange cover board, lower flange cover board can be used as I-beam
The rest of section during the installation process, accelerates speed of application, improves construction quality, adapts to the development of assembling type steel structure.
The system introduces active beam link design concept simultaneously, sets accentric support for anti-side device, active beam link plays
The effect of structure " fuse ", under violent earthquake load action, structure carries out energy dissipation, beam, column also by active beam link
It will not be surrendered in advance with support main member.
The advantages of this patent, is mainly manifested in the following aspects:
1, combination automatic runback device includes two toolings, a drag-line and two beam column node connection devices, is drawn with tradition
Rope automatic runback device is compared, in the identical situation of drag-line pretension, using the entirety of the bean column node of combination automatic runback device
Bearing capacity can be higher；In the identical situation of bearing capacity of bean column node, the drag-line prestressing force demand meeting of automatic runback device is combined
It reduces, is avoided that the excessive overstressing load to I-shaped beam section of drag-line prestressing force；By rationally designing Suo Li size, make structure most
The accumulation for controlling to big degree development and the damage of plastic deformation, makes structure have good anti-seismic performance and reset capability.
2, the system forms a kind of new support system by Y type diagonal brace and each main component and attachment device, with steel truss
Support is compared with rigid truss tube structure system, can be in the position of setting support while improving structure entirety lateral resistance behavior
It sets and opens up door opening.
3, to be arranged to inner cover board-like for top flange cover board in the system, and concrete outside top flange can be made more smooth, and bottom wing
Edge cover board is arranged to that outer cover is board-like, can be used as the rest of I-beam during the installation process, while being also convenient for node in use process
In edge of a wing cover board bending deformation is observed, the with good performance visual and replacement property sentenced.
4, each component of the system and nodal connection device welding portion are completed in factory, and weld seam precision and quality is more
Easy to control, each component is assembled only with high-strength bolt in scene, and the fastening work of bolt is convenient and efficient, improves construction speed
Degree and construction quality, adapt to the development of assembling type steel structure.
