Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and fig. 2, the replaceable steel beam with the buckling-restrained cover plate capable of rapidly repairing the earthquake damage in situ provided by the embodiment includes two sections of H-shaped steel beams 1 and 2, a flange connecting plate 3, a web connecting plate 4 and a buckling-restrained cover plate 5.
In this embodiment, the flange connecting plate 3 and the web connecting plate 4 are main energy consumption members, and the two steel beams 1 and 2 are connected together by friction type high-strength bolts 9. The buckling-restrained cover plate 5 is fixed on the outer side of the flange connecting plate 3 through bolts 9. When the anti-bending cover plate is installed, lubricating oil is coated on the interface of the anti-bending cover plate 5 and the flange connecting plate 3, so that the anti-bending cover plate does not transmit pulling pressure.
In this embodiment, the buckling-restrained cover plate 5 is provided with vertical stiffening ribs 11 in the middle, so as to improve the buckling-restrained capacity thereof. Particularly, one side of the buckling-restrained cover plate 5 is provided with a round hole, the other side of the buckling-restrained cover plate is provided with a long round hole, the length of the long round hole is 0.03 time of the height of the beam, and lubricating oil is coated between the interface of the buckling-restrained cover plate 5 and the flange connecting plate 6. Through the improvement, the buckling-restrained cover plate can be ensured not to provide tension and compression force under the action of reciprocating load.
The middle part of the flange connecting plate 3 is provided with a bolt hole, an oblong hole 10 is formed along the length of the plate to weaken the cross section, the weakening width is the same as the diameter of the bolt hole, the weakening section length is the distance between two bolts, and the contact surface of the flange connecting plate 3 and the steel beam 1 and the steel beam 2 is subjected to sand blasting treatment. Through the improvement, the bearing capacity design of the splicing area can be realized, and the damage is concentrated on the replaceable flange connecting plate.
