Embodiment 1
[0025] Such as Figure 1~4 Shown: a ribbed bamboo and wood restraint shearing plate, including a metal plate 1, peripheral restraining parts and connecting parts 3; the metal plate 1 is a metal plate with regular gaps, and protrudes through the upper and lower opposite sides Parts of the peripheral restraint parts are connected to the frame beams through the connecting parts 3; the peripheral restraint parts are composed of a bamboo board 2-1 and a stiffening rib 2-2; the stiffening rib 2-2 is a channel steel rib, and the bamboo board 2 -1 is located between the metal plate 1 and the stiffening rib 2-2 and isolates them; the bolt 4 passes through the stiffening rib 2-2 and the bamboo and wood plate 2-1 to form constraints.
Embodiment 2
[0027] Such as Figure 5 Shown: this embodiment is the same as the rest of embodiment 1, the difference is that: the stiffening ribs 2-2 are angle steel ribs.
Embodiment 3
[0029] Such as Figure 6 Shown: this embodiment is the same as the rest of embodiment 1, the difference is that the stiffening ribs 2-2 are T-shaped steel ribs.

The invention discloses a ribbed bamboo and wood constrained shearing plate, which comprises a metal plate, peripheral constraining parts and connecting parts; the two sides of the metal plate are provided with peripheral constraining parts, and the peripheral constraining parts pass through the bamboo and wood plate and stiffening ribs The bolts are pulled in pairs; the bamboo and wood board is a composite bamboo board or a composite wood board, and the bamboo and wood board is located between the metal board and the stiffening rib, and the two are isolated to avoid electrochemical corrosion. The upper and lower sides of the metal board The portion extending beyond the peripheral constraining member is secured to the structure by the connecting member. The bamboo wood plate of the present invention isolates the metal plate from the stiffening ribs to avoid electrochemical corrosion between different metals, and the bamboo wood plate and the stiffening ribs jointly form a peripheral restraining component to enhance its buckling restraint ability on the metal plate. At the same time, using bamboo and wood slabs to replace traditional concrete restraint components is not only more economical, meets environmental protection requirements, and can be used in corrosive environments.
Description
technical field [0001] The invention belongs to the field of civil engineering, and relates to a ribbed bamboo and wood constrained shear plate for reducing the impact of earthquake disasters on engineering structures. Background technique [0002] Buckling-constrained shear plate is a device that uses metal yield hysteresis to dissipate energy. Due to its stable performance, convenient fabrication, and low cost, it has attracted extensive attention in recent years. [0003] At present, the buckling-restrained shear plates commonly used in engineering in my country are mainly composed of steel plates or concrete slabs as peripheral restraint components. The restraint components do not directly bear the shear load, and can restrain the metal plate under the action of shear force under the action of horizontal shear force. The low-order buckling of , makes the hysteretic curve of the buckling-constrained shear plate plump. [0004] However, if aluminum alloy is used as the cor...
