Embodiment

[0025] by Figure 1-3 A shear-type buckling-restrained brace is shown as an example to illustrate this patent.

[0026] An all-steel visible shear-type buckling-restrained brace, the buckling-restricted brace includes a shear-type core material 1, a visually constrained plate 3 and a filling plate 2, two filling plates 2 are arranged on the On the left and right sides of the cut core material 1, there are two visual restraint plates 3, which are respectively arranged on the upper and lower sides of the shear core material 1 and the filler plate 2, and are fixedly connected to the filler plate 2 by bolts 5, The shearing core material 1 is fixed to the visible constraining plate 3 through anti-slip keys 4, and a plurality of shearing units 11 are arranged thereon.

[0027] The shearing core material 1 is a rectangular steel plate whose left and right shapes are symmetrical to the longitudinal axis of symmetry. The shearing units 11 are respectively arranged on both sides of the...

Abstract

The invention relates to an all-steel visualized shear type buckling constraint support. The all-steel visualized shear type buckling constraint support comprises a shear type core material, two visualized constraint plates and two filling plates. The two filling plates are arranged on the left side and the right side of the shear type core material respectively, the two visualized constraint plates are arranged on the upper side and the lower side of the shear type core material and the upper sides and the lower sides of the filling plates respectively and fixedly connected with the filling plates through bolts, the shear type core material is fixed to the visualized constraint plates through antiskid keys, and multiple shear units are arranged on the shear type core material. Compared with the prior art, the all-steel visualized shear type buckling constraint support has the advantages that the support is made of all steel, the dead weight is low, shear stress is stable, pulling and pressing bearing force is equal, visualization is achieved, the support is more visual, burdens on beams and columns are reduced, and no binding material is used.

Description

technical field [0001] The invention relates to the field of anti-seismic design and reinforcement reconstruction of structures such as buildings and bridges, in particular to an all-steel visible shear type buckling restraint support. Background technique [0002] Most of the restraining members of the existing buckling-restrained braces are steel pipes filled with mortar. This type of brace is often unstable due to the difficulty in controlling the pouring quality of the mortar, and its self-heavy weight is not conducive to engineering construction and installation, and will cause the structure to be too large additional seismic force. In addition, most of the existing buckling-constrained supports absorb energy through axial deformation generated by axial force. The load asymmetry of the structure under the action of tension and pressure causes the design process to consider that the excessive compressive bearing capacity will cause damage to the joints. The requirements...
