Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a connection structure between a buckling-restrained brace and a beam. Background Technique

[0002] BRB, also known as buckling-restrained brace structure, is a structure used to enhance the overall strength in the construction industry. The common frame BRB structure mostly consists of two obliquely arranged support rods connected to the frame to improve the strength of the middle space of the frame.

[0003] In the related art, a buckling-restrained brace structure is designed. One end of each of the two support rods is connected to the frame, and the other end is connected and arranged on the ground, showing an inverted V shape to enhance the stability of the connection and fixation of the frame.

[0004] When actually installing the above buckling-restrained brace structure, a connecting plate will be pre-buried and inserted into the ground as a casting foundation first. The connecting plate is fixed on the ground, and the end of the support rod far from the frame is fixed on the connecting plate by welding or other means to complete the installation of the buckling-restrained brace structure. However, the operation of pre-burying and fixing the connecting plate needs to be actually carried out at the construction site. Breaking the ground for installation and fixation is rather cumbersome, with a long construction time and a large construction workload, making the on-site construction less convenient.
