To reach above-mentioned purpose, replaceable H described in the utility model, U-shaped mild steel combination of dampings device include upper connection Plate, lower connecting plate and some power consumption modules, wherein, each module that consumes energy is between upper junction plate and lower connecting plate, and respectively consume energy mould Block includes the first H profile steel, the second H profile steel and U-shaped steel plate, wherein, the top flange of the first H profile steel is connected with upper junction plate, The lower flange of first H profile steel is connected with the side of U-shaped steel plate, and the top flange of the second H profile steel is connected with the opposite side of U-shaped steel plate Connect, the lower flange of the second H profile steel is connected with lower connecting plate, and is provided with upper junction plate and lower connecting plate outer for connecting The screwed hole of portion's equipment.
Between the top flange of first H profile steel and upper junction plate, between the lower flange of the first H profile steel and U-shaped steel plate, the 2nd H Pass through high-strength bolt phase between the top flange of shaped steel and U-shaped steel plate and between the lower flange of the second H profile steel and lower connecting plate Connection.
The quantity for the module that consumes energy is four, and four modules circumferentially equidistantly distributeds that consume energy.
The number of the upper screwed hole of upper junction plate 1 is four, the position that the top flange of the first H profile steel is connected with upper junction plate Circumferentially it is interspersed with the position of upper junction plate upper screwed hole.
The number of lower connecting plate upper screwed hole is four, the position that the lower flange of the second H profile steel is connected with lower connecting plate Circumferentially it is interspersed with the position of lower connecting plate upper screwed hole.
The utility model has the advantages that:
In concrete operations, U-shaped steel plate passes through for replaceable H described in the utility model, U-shaped mild steel combination of dampings device One H profile steel is connected with upper junction plate, and U-shaped steel plate is connected by the second H profile steel with lower connecting plate, relative to traditional mild steel Damper, initial stiffness of the present utility model is larger, easy to process, and when inputting seismic energy, passes through the change of U-shaped steel plate Damping is realized in shape power consumption, and the hysteretic energy performance and low-Cycle Fatigue Characteristics of damper are preferable, and disclosure satisfy that the carrying of structure Power requirement.In addition, the utility model passes through the screwed hole on the screwed hole and lower connecting plate on upper junction plate and external equipment phase Connection, easy to disassemble and installation.
Further, it is connected between U-shaped steel plate and the first H profile steel and the second H profile steel by high-strength bolt, works as U-shaped steel After plate is destroyed, then the replacing of U-shaped steel plate can be realized by removing high-strength bolt, it is not necessary to whole damper is changed, Better economic benefit.
