Shearing wall constrained and galvanized iron sheet enveloped no-binding energy dissipating steel support and method for making same

The invention relates to a shear-wall constraint out-packing galvanized iron un-bonded energy consumption steel brace, belonging to the antiseismic area of frame-shear wall structure engineering. A reinforced bar mesh constituted by reinforced steel bars distributed in landscape (1) and portrait (2) directions is collocated. Linking reinforced steel bars (9) are set among reinforced bar meshes. Two soft steel braces are set in the middle of two reinforced steel meshes in cross. The galvanized iron (5) is set out of soft steel braces and it can separate the soft steel brace and the concrete. It also can play the constraint role of buckling behavior of soft steel braces. Stirrups (6) are set along two sides of the galvanized iron. When the shear wall is installed, there is a gap among frame beams (7), (8) and frame column (9). Two soft steel braces are set in cross to form ’™-shape or X-shape and the section of soft steel brace can be set in Ê”-shape, T-shape,—«-shape or˜ñ-shape. The invention improves the energy consumption ability of unbonded and buckling constraint brace and controls the structure deformation furthermore. The invention also improves the structure antiseismic ability.
