[0030] Such as Figure 1-3 As shown, a bamboo-wood filled buckling-restrained support includes a metal core component 1, bamboo-wood fiber filled components and peripheral constraint components;

[0031] The metal core component 1 adopts a straight member, the peripheral constraint component is a peripheral constraint flat plate 2, and the bamboo fiber filling component includes a filling flat plate 3-1 and a filling slat 3-2;

[0032] The metal core part 1 is arranged between two filling flat plates 3-1, the width of the filling flat plate 3-1 is greater than the width of the inline member of the metal core part 1, and the gap between the two filling flat plates 3-1 is provided with filling The slat 3-2; the filling plate 3-1 and the filling slat 3-2 are in close contact with the surface of the in-line member, leaving a gap; the peripheral constraining plate 2 is close to the outside of the filling plate 3-1, And the bolts 4 pass through the peripheral constraining plate 2, ...

Embodiment 2

[0034] Such as Figure 4-5 As shown, a bamboo-wood filled buckling-restrained support includes a metal core component 1, bamboo-wood fiber filled components and peripheral constraint components;

[0035] The metal core part 1 adopts a cross-shaped member, and the bamboo and wood fiber filling part includes a filling body 3-3 and a filling slat 3-2;

[0036] The four corners of the cross-shaped member of the metal core component 1 are respectively provided with four filling bodies 3-3, the width of each filling body 3-3 is greater than the length of the adjacent cross-shaped member, and the four filling bodies 3-3 Filling slats 3-2 are arranged in the gaps between them; the filling body 3-3 and the filling slats 3-2 are in close contact with the surface of the cross-shaped member, and a gap is left; the peripheral constraint parts are close to the filling body 3 -3 and fill the periphery of slats 3-2; the peripheral constraining parts use steel plates 2-1 and channel steels 2-...

Embodiment 3

[0038] Such as Figure 6-7 Shown: this embodiment is the same as the rest of embodiment 2, the difference is that: the peripheral constraining components are welded between steel plates 2-1 to form a box-shaped constraining structure.

Abstract

The invention discloses a bamboo-wood-filled buckling restrained support. The bamboo-wood-filled buckling restrained support comprises a metal core part, a bamboo-wood-fiber filling part and a peripheral restraining part, wherein the bamboo-wood-fiber filling part is positioned between the metal core part and the peripheral restraining part and separates the metal core part and the peripheral restraining part so as to avoid from forming electrochemical corrosion. The bamboo-wood-filled buckling restrained support has the advantages that bamboo-wood fiber is filled between the metal core part and the peripheral restraining part, and the bamboo-wood-fiber filling part is positioned between the metal core part and the peripheral restraining part and separates the metal core part and the peripheral restraining part so as to avoid from forming the electrochemical corrosion; a flat plate and a rectangle and the like can be selected as the section form of the bamboo-wood-fiber part according to the form of the metal core part, and bamboo wood is adopted as a filling material to replace the traditional concrete, so that not only is the mass lighter, but also the recycling is easy, and the requirement for environmental protection is met.

Description

technical field [0001] The invention belongs to the field of civil engineering and relates to a buckling constrained support for reducing the impact of earthquake disasters on engineering structures. Background technique [0002] Buckling-restrained brace is a device that uses metal yield hysteresis to dissipate energy. Due to its stable performance, convenient fabrication, and low cost, it has been widely studied and applied in recent years. [0003] At present, the buckling-restrained braces commonly used in engineering in my country are mainly divided into two types according to the restraint components: ① inner-filled concrete or mortar steel pipe restraint components; ② all-steel restraint components made of section steel. The constrained components do not bear the axial load directly, and can suppress the low-order buckling of the core components under the action of external pressure. The core components yield at the full cross-section under the action of tension and p...
