Problems solved by technology

Since the core steel plate does not have sufficient tensile and compressive deformation capacity, the core steel plate will yield or buckle under compression, and the force mode of steel plate bending cannot be realized, resulting in insufficient bending energy dissipation capacity at both ends of the steel plate. Play, the performance of the damper can not reach the best

Embodiment 1

[0028] Such as image 3 , Figure 4 The tensile and compression yielding metal bending energy dissipation damper shown in the present invention includes an upper connecting plate 1, a lower connecting plate 2 and a core steel energy dissipating element. The core steel energy dissipating element includes three pairs arranged perpendicular to the upper and lower connecting plates. Steel plates, the steel plates are composed of the upper energy dissipation plate 4 and the lower energy dissipation plate 5, wherein one end of the upper energy dissipation plate 4 and one end of the lower energy dissipation plate 5 are firmly welded to the upper connecting plate 1 and the lower connecting plate 2, respectively The other end of the upper energy dissipating plate 4 and the other end of the lower energy dissipating plate 5 are overlapped with each other, and the through holes provided on the upper and lower energy dissipating plates are connected together by fasteners 6 at the overlap. In...

Embodiment 2

[0037] Such as Figure 7 , Figure 8 , Picture 9 The difference between the tensile and compression yielding metal bending energy dissipation damper of the present invention shown in the first embodiment is that a steel plate composed of five upper and lower energy dissipation plates is set as a core steel energy dissipation element. The through holes on the upper energy dissipating plate 4 and the lower energy dissipating plate 5 are changed to be provided with a notch 13. Since the material, shape and size of the upper and lower energy dissipating plates are exactly the same, they are used here. Figure 8 Give instructions. In addition, the upper energy dissipating board 4 and the lower energy dissipating board 5 are arranged in a staggered order, that is, as Picture 9 As shown in the structure, the upper energy dissipating plate 4 and all adjacent lower energy dissipating plates 5 are kept in contact with each other or a certain gap is kept within the range of the overlappin...

Abstract

The invention discloses a metal bending energy-consuming damper for preventing the tension and compression and yield, belonging to the technical field of structure shock absorption of civil engineering. The metal bending energy-consuming damper is characterized by comprising an upper connecting plate and a lower connecting plate which are fixed on a building structure as well as a core metal energy-consuming element, wherein the core metal energy-consuming element comprises at least one pair of upper energy-consuming plate and lower energy-consuming plate; one end of the upper energy-consuming plate is fixedly connected with the upper connecting plate and the lower connecting plate; the other end of the upper energy-consuming plate and one end of the lower energy-consuming plate are mutually lapped; the other end of the lower energy-consuming plate is fixedly connected with the lower connecting plate; the upper energy-consuming plate and the lower energy-consuming plate are vertical to the upper connecting plate and the lower connecting plate; and the thickness directions of the upper energy-consuming plate and the lower energy-consuming plate are consistent with the direction of shearing force born by a building or bridge structure. The invention has the characteristics of large deformation amount and tension and compression and yield prevention, novel and reasonable structure, easy processing as well as convenient and flexible use and strong adaptability. In addition, the invention can effectively improve the quakeproof performance of a building structure and a bridge structure and has a broad market popularization and application prospect.

Description

Technical field [0001] The invention belongs to the technical field of structural shock absorption in civil engineering, and specifically relates to a component arranged between a bridge pier and a beam slab or an energy-consuming component of a building structure in bridge engineering, in particular to a metal damper used for shock-absorbing and energy-consuming. Background technique [0002] The development of today's buildings tends to be more and more tall. The frame structure composed of steel members, composite members or reinforced concrete members is a structural form often used in buildings. In order to make the building structure have a strong resistance to external damage such as earthquake or wind load, it is often necessary to add metal energy-dissipating components to the frame structure. The development of bridge engineering is also becoming more and more large-scale. In order to ensure the safety of the bridge structure during earthquakes and prevent bridge fallin...
