Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the existing technology, and propose a metal damper with multiple shear webs, which overcomes the large-tonnage metal damper steel plate that is prone to out-of-plane buckling due to its large area, and the large-tonnage The defect that the length and weight of the metal damper become larger

Embodiment 1

[0027] Such as figure 1 (a), figure 2 (a), image 3 As shown in (a), on the outer surfaces of the two shear webs 1, there are two vertical stiffeners 3, two horizontal stiffeners 3, and two vertical stiffeners 3. The plate 3 and the two stiffening plates 3 in the horizontal direction intersect each other in a cross shape.

Embodiment 2

[0029] Such as figure 1 (b), figure 2 (b), image 3 As shown in (b), on the outer surfaces of the two shear webs 1, two stiffening plates 3 intersecting along different diagonals are respectively provided throughout the entire length, and the two stiffening plates 3 intersecting along different diagonals are connected to each other. Cruciform cross.

Embodiment 3

[0031] Such as figure 1 (c), figure 2 (c), image 3 As shown in (c), on the outer surfaces of the two shear webs 1, five pairs of cross-shaped stiffening plates 3 are partially provided, and the five pairs of cross-shaped stiffening plates 3 are located on the outer surfaces of the shear webs 1. Set symmetrically on the sides. One pair is located at the center of the outer surface of the shear web 1 , and the remaining four pairs are located at the inner sides of the four right angles of the shear web 1 .

[0032] see figure 1 (d-h), figure 2 (d-h), image 3 (d-h) are five embodiments in the case where the distance between two shear webs 1 is relatively large. A stiffening plate 3 is arranged between the two shearing webs 1 , and the two sides of the stiffening plate 3 are respectively welded to the inner surfaces of the two shearing webs 1 . The stiffeners 3 on the outer sides of the two shear webs 1 are designed symmetrically, and the number, direction and size of t...

Abstract

The invention discloses a metal damper provided with multiple shearing webs. The metal damper provided with the multiple shearing webs comprises the shearing webs, horizontal connecting steel plates, flange plates and stiffening plates, wherein the horizontal connecting steel plates are arranged above and below the shearing webs respectively, the flange plates are arranged at two ends of the shearing plates, the stiffening plates are arranged on the lateral surfaces of the shearing webs, the shearing webs are welded to the upper horizontal connecting steel plate and the lower horizontal connecting steel plate, the shearing webs are welded to the flange plates at the two ends, the stiffening plates are welded to the shearing webs, the number of the shearing webs is at least two, the adjacent shearing webs are parallel with each other, and the intervals between the shearing webs are equal or different. The metal damper provided with the multiple shearing webs utilizes the advantage that the initial rigidity is large when the plane of the shearing webs is stressed, prevents the plane of the shearing webs from being bent outwards through the method of arranging the two shearing webs and the different stiffening plates, and guarantees energy consumption capacity and stability. When the needed tonnage is large, the weight and length of the metal damper with the two shearing webs are smaller than those of a metal damper with one shearing web.

Description

technical field [0001] The invention relates to the anti-seismic technical field of building engineering structures, in particular to a metal damper provided with a plurality of shear webs. Background technique [0002] The energy dissipation and shock absorption of building structures refers to the installation of appropriate energy dissipation components in the building structure. The energy dissipation components can be composed of energy dissipation and shock absorption devices and supporting components such as diagonal braces, walls, beams or nodes. The metal damper is an energy-dissipating shock-absorbing device with superior energy-dissipating performance, simple structure, convenient manufacture, low cost and easy replacement. It can be used as an energy-dissipating unit or a limiting device in conjunction with a seismic-isolation support or a seismic-isolation system, and can be used alone in a building structure as an energy-dissipating device to provide additional...
