Description
Technical Field
The utility model relates to a metal yield damper with a T-shaped cross section, and belongs to the technical field of energy dissipation and shock absorption of structures of civil engineering.
Background
At present, the damper is widely applied to the field of seismic isolation control of engineering structures, and can improve the damping ratio of building structures, so that the structural seismic response is reduced. The energy dissipation capacity of the novel damper is realized by the bending plastic deformation of the T-shaped section steel a plate. The damper is oval in appearance and is formed by combining two steel plates with T-shaped sections and an upper connecting plate and a lower connecting plate. The T-shaped section steel plate comprises an upper straight line section, a circular arc section and a lower straight line section. When the upper straight line segment on one side of the damper is pulled, the upper straight line segment is stretched and the lower straight line segment is shortened, and the upper straight line segment on the other side is shortened and the lower straight line segment is stretched, or vice versa. Compared with the similar U-shaped steel plate damper, the damper has higher strength and rigidity, higher material utilization rate and more space saving. The damper is simple in form and convenient to process, install and disassemble.
SUMMERY OF THE UTILITY MODEL
The U-shaped steel ribs are welded on the inner sides of the U-shaped steel plates to form T-shaped sections. The energy consumption capability of the damper comes from the bending plastic deformation of the T-shaped section steel plate, steel can be efficiently utilized, and the damper has high yield strength and rigidity.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a crawler-type metal yield damper based on a T-shaped section mainly comprises a U-shaped steel plate, U-shaped steel ribs and a connecting plate. The two rectangular steel plates are hot-rolled and cold-bent to form a U-shaped steel plate 1, two U-shaped steel ribs are welded on the inner side of the U-shaped steel plate to form two T-shaped section steel plates respectively, and then the two T-shaped section steel plates are welded with the connecting plate to form the oval damper. The damper can be used for a shock insulation support, and can also be arranged between wallboards for energy dissipation and shock absorption. Four bolt holes are reserved on the connecting plate, and the damper can be connected with a building through bolts. The U-shaped steel plate is formed by three sections which are sequentially connected in a transition mode and are respectively an upper straight section and a circular arc section) and a lower straight section.
When the upper straight line segment on one side of the damper is pulled, the upper straight line segment is lengthened, the lower straight line segment is shortened, the upper straight line segment on the other side of the damper is shortened, and the lower straight line segment is lengthened. The circular arc section and the U-shaped steel rib circular arc section are subjected to bending plastic deformation, and the damper consumes energy.
When the upper straight line segment part on one side of the damper is pressed, the upper straight line segment part is shortened, the lower straight line segment part is lengthened, the upper straight line segment part on the other side of the damper is lengthened, and the lower straight line segment part is shortened. The circular arc section and the U-shaped steel rib circular arc section are subjected to bending plastic deformation, and the damper consumes energy.
When the crawler-type metal yield damper with the T-shaped section is used for a shock insulation support, the crawler-type metal yield damper with the T-shaped section is used as a shock insulation layer between an upper structure and a foundation under the condition of earthquake, and the energy of the earthquake can be consumed through the plastic deformation of the arc section so as to protect the upper structure.
When the crawler-type metal yielding damper with the T-shaped section is arranged between the wallboards, under the condition of earthquake, the damper consumes earthquake energy through plastic deformation of the arc section, and the wallboards cannot slip.
Compared with the prior art, the utility model has the following advantages:
(1) according to the utility model, the steel ribs are welded on the inner side of the U-shaped damper to form the T-shaped section, so that the yield strength and the rigidity can be effectively improved.
(2) Under the condition of meeting the yield strength and the rigidity, the material can be effectively saved, and the damper has compact shape and saves space.
The common U-shaped steel plate damper consumes energy through plastic deformation of the circular arc section, however, the T-shaped section steel plate has one more steel rib in the middle than the common U-shaped steel plate, the thickness of the steel plate is increased, and the energy consumption of the crawler-type metal yield damper with the T-shaped section consists of two parts, namely circular arc section energy consumption of the U-shaped steel plate and circular arc section energy consumption of the U-shaped steel rib.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
1-5, a crawler-type metal yielding damper based on a T-shaped section is implemented as follows: the U-shaped steel plate 1, the U-shaped steel ribs 2, the connecting plates 3 and the like are prefabricated in advance in a factory. The U-shaped steel plate 1 is formed by cold-bending a common steel plate with a corresponding size into a U shape after hot rolling. The U-shaped steel rib 2 is formed by cutting the U-shaped steel rib 2 on a steel plate 8 with a certain thickness. The U-shaped steel rib 2 is welded to the U-shaped steel plate 1 to form a T-shaped section. And welding the steel plate with the T-shaped section with the connecting plate to form the elliptical crawler-type metal yield damper with the T-shaped section, and then transporting the damper to a construction site. The connecting plate is provided with a bolt hole 7, so that a damper can be installed conveniently during testing.
