Benefits of technology

The present invention provides a buckling restrained brace that can alleviate the drawbacks of conventional buckling restrained braces. The buckling restrained brace is adapted to be connected fixedly between two connecting plates of a framework of a building. It includes a rigid restraining unit and an axial member. The axial member has a middle section, a pair of first coupling sections, and a pair of second coupling sections. The first coupling sections are connected respectively and perpendicularly to opposite longitudinal end portions of the middle section, and each has a first coupling groove for engaging a connecting plate. The second coupling sections are connected respectively and perpendicularly to the opposite longitudinal end portions of the middle section, and each has a second coupling groove for engaging a connecting plate. The technical effects of this invention include improved stability, reduced movement, and increased security of the brace.

Problems solved by technology

However, the restraining unit 12 generally has a square or round cross-section, and the conventional buckling restrained brace 1 has a relatively heavy weight and a relatively large volume, thereby resulting in inconvenience when being assembled to the steel framework 13, and occupying a relatively large space within the building.

Embodiment Construction

[0038]Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.

[0039]Referring to FIG. 2, the first preferred embodiment of a buckling restrained brace 201 according to the present invention is adapted to be connected fixedly between two connecting plates 9 of a steel framework of a building. The buckling restrained brace 201 comprises a rigid restraining unit 3 and an axial member 4.

[0040]Further referring to FIGS. 3 to 5, the restraining unit 3 includes a surrounding member 31 extending in an axial direction (X) and having opposite longitudinal ends. In this embodiment, the surrounding member 31 is formed with an inner surrounding surface 311 (see FIG. 7).

[0041]The axial member 4 includes a middle section 41, a pair of first coupling sections 42, and a pair of second coupling sections 43.

[0042]The middle section 41 extends in the axial direction (X), and is surrounded by ...

Abstract

A buckling restrained brace is for connection between two connecting plates of a framework, and includes a restraining unit and an axial member. The axial member includes a middle section surrounded by the restraining unit, two first coupling sections, and two second coupling sections. The first coupling sections are connected respectively and perpendicularly to opposite longitudinal end portions of the middle section. Each first coupling section has a portion exposed from a respective one of longitudinal ends of the restraining unit, and is formed with a first coupling groove for engaging a respective one of the connecting plates. The second coupling sections are connected respectively and perpendicularly to the opposite longitudinal ends of the middle section. Each second coupling section has a portion exposed from a respective one of the longitudinal end portions of the restraining unit, and is formed with a second coupling groove for engaging a respective one of the connecting plates.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priorities of Taiwanese Application Nos. 099108880 and 099205208, filed on Mar. 25, 2010.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a buckling restrained brace, more particularly to a buckling restrained brace that is adapted to be connected fixedly between two connecting plates of a framework of a building.[0004]2. Description of the Related Art[0005]A buckling restrained brace is generally used in a steel framework of a building for absorbing vibration energy generated by an earthquake so as to minimize damage to the framework resulting from the shock of the earthquake.[0006]As shown in FIG. 1, a conventional buckling restrained brace 1 is provided between two connecting plates 14 of a steel framework 13 of a building, and includes an axial member 11 and a restraining unit 12 that surrounds the axial member 11. The axial member 11 has end portions longitudinally oppos...
