[0002] With the development of design and manufacturing capabilities, buckling restrained braces have begun to be widely used in earthquake-resistant structures. Buckling braces are mainly composed of core materials (internal energy dissipation components), outer sleeves (external restraint components), and non-bonded materials in the sleeves. Non-bonded isolation materials are used as core isolation materials to eliminate the friction between the inner steel core and the outer restraint sleeve, so that the inner steel core can expand and contract freely without restraint. At the same time, the core material is protected from corrosion by the filling material. Rubber, silicone, latex, SBS waterproof membranes with waterproof and moisture-proof properties are usually selected.

[0003] The following defects or deficiencies exist during the use of the core material:

[0004] 1. When construction is carried out in winter, affected by the local natural environment and low temperature environment, the above materials will become cold and brittle and fail to function during construction, and their construction efficiency is low, or it is almost impossible to construct, and they cannot meet the design requirements and thus cannot be constructed in winter;

[0005] 2. The uneven appearance becomes an obstacle to large-scale promotion in the market. Utility Model Content
