The objective of the invention is to be achieved through the following technical solutions:
Construction steel plate energy consumer, when bolt connected, the steel plate energy consumer comprised fixed position and power consumption position two parts, fixed position adopts rectangular in form, and bolt hole is set therein; Arc or slick and sly polygon form that the middle position outline employing of consuming energy concaves, inside adopts circle, ellipse or slick and sly polygon cutting to draw the hole.
Construction steel plate energy consumer, when being welded to connect, directly be welded on the two ends at power consumption position on the fastening devices, the steel plate energy consumer is gone up for how much and is adopted symmetric arrangement, an ellipse or circle or polygon are adopted in middle power consumption position, perhaps a plurality of ellipses or circle or polygon are drawn the hole, adopt horizontal or vertically in a symmetrical arrangement when a plurality of ellipses or circle or polygon.
Described construction steel plate energy consumer, the fixedly connected form of its construction steel plate energy consumer comprise connecting angle, connect steel plate and ribbing steel plate formation.
Described construction steel plate energy consumer, the fixedly connected form of its construction steel plate energy consumer comprise connecting angle, connect steel plate and flute profile strengthening steel slab formation.
Described construction steel plate energy consumer, the fixedly connected form of its construction steel plate energy consumer comprise connecting angle, connect steel plate and ribbing steel plate and connecting angle, be connected steel plate and flute profile strengthening steel slab both in conjunction with formation.
Advantage of the present invention and effect are:
Steel plate energy consumer initial stiffness is big, no obvious stress concentration phenomenon, steel surrender area greatly, power consumption is effective, steel utilization ratio is high, making, the installation of while steel plate energy consumer are simple, easy to use, and the seismic design that both can be used for new construction also can be used for the reinforcing maintenance of existed building.
