Specifically, the earthquake-resistant building wall 100 includes a beam 112, a column 114, and a first gusset 113 connected to the beam 112 and a second gusset 115 connected to the column 114. The columns 114 and the beams 112 belong to main structural members of a building, and the beams 112 and the columns 114 extend along the edges of the wall 110 respectively.

In the present embodiment, the first gusset plate 113 and the second gusset plate 115 are both made of Q345B steel. When an earthquake occurs, the first gusset plate 113 and the second gusset plate 115 deform relatively little, and have little influence on the wall 110, and generally do not cause damage.
Therefore, one end of each buckling-restraining support 130 is connected to the first gusset plate 113, the other end of each buckling-restraining support 130 is connected to the second gusset plate 115, a single buckling-restraining support 130 is inclined, one end of each buckling-restraining support 130 is connected to the first gusset plate 113, and the two buckling-restraining supports 130 form a herringbone shape.

In this embodiment, the buckling-restrained brace 130 includes a core material 134 and an outer steel tube 132 sleeved outside the core material 134. The outer steel pipe 132 is a quadrangular prism, and the cross section thereof is square. The core material 134 has a cross-shaped cross-section, and both ends of the core material 134 are exposed out of the outer steel pipe 132.

So that the buckling-restrained brace 130 is isolated from the wall 110 by the angle iron 152. In order to avoid the influence of the presence of the angle iron 152 on the deformation of the buckling-restrained brace 130 in an earthquake, which may result in active energy-consuming deformation of the buckling-restrained brace 130, a gap 170 exists between each angle iron 152 and the buckling-restrained brace 130. In other embodiments, 3 or 5 angles may be used to surround buckling-restrained brace 130, and only a plurality of angles 152 may surround buckling-restrained brace 130 according to the specific shape of buckling-restrained brace 130, so as to space buckling-restrained brace 130 from wall 110.

In other embodiments, adjacent angles 152 may contact each other to form a 360 ° fully enclosed structure.
To avoid affecting the energy consuming deformation of the buckling restrained brace 130 while ensuring structural stability, the gap 170 is filled with a fiber-based elastic material 172. In this embodiment, the gap 170 is 50mm and the fiber-based elastic material 172 is rock wool. The rock wool has excellent heat preservation, heat insulation and fireproof functions and is suitable for building equipment and the like. In other embodiments, the fiber-based elastic material 172 may also be glass wool. The surface of the fiber elastic material 172 close to the isolation structure 150 and the surface of the buckling restrained brace 130 are coated with a galvanized iron wire mesh to enhance the shaping effect of the fiber elastic material 172 and improve the mechanical property.

The periphery of buckling-restraining support 130 is provided with an isolation structure 150, isolation structure 150 including a plurality of angle steels 152 arranged opening toward buckling-restraining support 130. The length of angle iron 152 is no less than the length of buckling-restrained brace 130, and each angle iron 152 has one end connected to first gusset plate 113 and the other end connected to second gusset plate 115, such that buckling-restrained brace 130 is isolated from wall 110 by angle iron 152. When an earthquake occurs, the deformation of the first gusset plate 113 and the second gusset plate 115 is small, and the deformation generated when the angle steel 152 is connected to the gusset plates is also small, so that the wall body 110 cannot be greatly influenced, the integrity of the wall body 110 is effectively protected, and the personnel safety is better ensured.
Earthquake-resistant building wall 100 separates buckling restrained brace 130 and wall body 110 through being provided with isolation structure 150 in buckling restrained brace 130's periphery, reduces buckling restrained brace 130 and causes direct influence to wall body 110 when taking place to draw and press the deformation in the earthquake, improves the problem of wall body 110 deformation fracture, improves reliability and the security of wall body 110 in the earthquake.
