Problems solved by technology

Because the yield point of the metal materials used in the metal shear support steel plate is usually high, it is difficult to enter the state of energy consumption under the action of strong wind, so this type of support steel plate can only function under moderate and large earthquakes, and it is suitable for small earthquakes. sex needs improvement

Embodiment 1

[0025] Such as figure 1 , 2 . As shown in 3, the connecting beam type metal supporting steel plate includes a supporting steel plate 1 (the number of supporting steel plates can be multiple, depending on the needs), and the supporting steel plate 1 is a shear force type metal support plate or a bending force type metal support plate. Support steel plate. The left and right sides of the supporting steel plate 1 are respectively connected with a buffer transition plate 3, and the supporting steel plate 1 and the buffer transition plates 3 on both sides are connected by welding. The other side of the buffer transition plate 3 is connected to a buckling device 2. The buckling device 2 on the left side of the supporting steel plate 1 and the buckling device 2 on the right side of the supporting steel plate 1 have the same or different structures. The buffer transition plate 3 and the buckling device 2 on the same side are both Placed inside the same building structure connecting ...

Embodiment 2

[0027] Such as Figure 4 As shown, the buckling device 2 in this embodiment adopts a combined structure of anchor tendons or anchor bolts 21 and shear keys 22, and the rest of the structure is the same as in Embodiment 1. The shear key 22 is a small buffer transition plate. The buffer transition plate 3 and the anchor bars or anchor bolts 21 are connected by welding, and the buffer transition plate 3 and the small buffer transition plate 22 are connected by welding. The small buffer transition plate 22 is located in the middle, and two rows of anchor bars or anchor bolts 21 are respectively welded on the upper and lower ends of the small buffer transition plate 22, and the anchor bars or anchor bolts 21 at the upper and lower ends are symmetrically arranged on the buffer transition plate 3. on the side.

Embodiment 3

[0029] Such as Figure 5 As shown, in this embodiment, the buckling device 2 adopts a combined structure of anchor tendons or anchor bolts 21 and a shear key 22, and two rows of bolt holes are arranged on the side of the shear key 22, and a stud 23 is fixed in the bolt hole , the rest of the structure is the same as in Example 2.

Abstract

The invention discloses a buckling-restrained energy dissipation support. The buckling-restrained energy dissipation support comprises at least one supporting steel plate, wherein the left side and the right side of each supporting steel plate are each connected with a buffer transition plate; the other side of each buffer transition plate is connected with a buckling device; the buckling deviceson the left sides of the supporting steel plates and the buckling devices on the right sides of the supporting steel plates are the same or different in structure; the buffer transition plates and thebuckling devices on the same side are arranged in a same building structure connecting beam; the building structure connecting beam is connected with a main body structure wall; the supporting steelplates are shear stress type metal supporting steel plates or bending stress type metal supporting steel plates; the buckling devices are anchor bars or anchor bolts; the buckling devices are combinations of the anchor bars or the anchor bolts and shear keys; the shear keys are small buffer transition plates; bolt holes are formed in the side faces of the shear keys; and studs are fixed in the bolt holes. The support can play a role in consuming earthquake energy and protecting a main body structure, and the condition that a connecting beam part of a traditional building structure is prone tobeing damaged is improved.

Description

technical field [0001] The invention relates to an energy-dissipating shock-absorbing device for a building structure, in particular to an anti-buckling energy-dissipating support. Background technique [0002] The metal shear support steel plate is a passive energy-dissipating device commonly used in the construction field. Its basic principle is to use the plastic hysteretic deformation of the metal to consume vibration energy. After entering the plastic state, it has outstanding hysteretic characteristics. It has simple structure, It has the characteristics of stable hysteretic performance, low cost, and clear mechanical model. Because the yield point of metal materials used in metal shear support steel plates is usually high, it is difficult to enter the state of energy consumption under the action of strong winds. Therefore, this type of support steel plates can only function under moderate and large earthquakes. Sex needs improvement. [0003] As another widely used ...
