Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] see Figure 1-8 , the Z-shaped sleeve constrains the in-line pure steel buckling restraint support, which is composed of in-line core steel plate 1, small-diameter round steel 2, large-diameter round steel 3, peripheral constraint sleeve 4, and unbonded structural layer 5 (because this layer is too Thin, can't be shown in the figure) and stiffening plate 6, wherein the specific structural shape of each component and the connection relationship between each other are as follows.

[0033] Figure 1-8 It shows an embodiment of the present invention and Z-shaped sleeve constrained in-line pure steel buckling restraint support, including a core plate 1 with an in-line cross section and a peripheral constraining sleeve 4 sleeved on the core plate 1, the peripheral On the upper and lower inner walls of the constraining sleeve 4, four small-diameter ro...

Abstract

The invention relates to a zigzag pure steel buckling restraint brace constrained by a Z-shaped sleeve and a manufacturing method thereof, comprising a core plate with a cross section of a glyph, a non-adhesive material layer, and a peripheral restraint sleeve sleeved on the core plate The cross-section of the peripheral restraining sleeve is Z-shaped, and two full-length small-diameter round steels are respectively arranged at 1 / 3 of the inner walls of the flanges on the upper and lower sides in the length direction. The small-diameter round steel and the peripheral restraining sleeve The inner wall of the core plate is attached and fixedly connected, the outside of the core plate is wrapped with a layer of non-adhesive material, and the core plate wrapped by the layer of non-adhesive material is tightly attached to the outer constraint sleeve. In the present invention, the two sides of the core plate are respectively clamped in the Z-shaped sleeve web restraint to realize the surface contact restraint, which improves and utilizes the ability of the core material to resist local buckling, and does not need to be filled with restraint material, so that the self-weight is greatly reduced. The utilization rate of steel is very high, so as to achieve better economy.

Description

technical field [0001] The invention relates to an earthquake-resistant and disaster-preventing building structure, in particular to a shock-absorbing structure belonging to the category of passive control, in particular to a Z-shaped sleeve constrained in-line pure steel buckling constrained support and a manufacturing method thereof, which can be used in building structures Resist horizontal earthquake action and improve the seismic performance of the structure. Background technique [0002] Buckling-restrained brace is a structural member that can not only provide lateral stiffness without instability, but also stably realize energy dissipation and shock absorption under strong earthquakes. Experiments have shown that setting buckling-restrained braces in concrete frames can greatly increase the bearing capacity and improve the seismic performance of the structure. It is expected to replace some shear walls and increase the height of the frame structure. In addition, the...
