Abstract

The invention discloses a hierarchical energy consumption damper, which comprises two substrates distributed at intervals; a first yielding energy consumption piece and a second yielding energy consumption piece are arranged between the two substrates; two ends of the first yielding energy consumption part are respectively and fixedly connected with the two substrates; one end of the second yielding energy dissipation part is fixedly connected to one of the base plates, and the other end of the second yielding energy dissipation part is directionally and slidably connected to the other base plate. Under the action of a small shock, the second yielding energy dissipation part is in an elastic state and does not have the action of damping and dissipating energy, so that only the first yielding energy dissipation part can damp and dissipate energy independently; under the action of medium and large earthquakes, the second yielding energy dissipation piece begins to bend and deform so as to achieve the purpose of yielding energy dissipation, and therefore the second yielding energy dissipation piece and the first yielding energy dissipation piece jointly consume earthquake energy. Therefore, the first yielding energy dissipation part and the second yielding energy dissipation part of the graded energy dissipation damper yield in a graded mode, and the graded energy dissipation damper has an obvious graded yielding energy dissipation effect.

Technical Field
The invention relates to the technical field of disaster prevention and shock absorption, in particular to a hierarchical energy consumption damper.
Background
Since the occurrence of an earthquake generally accompanies the sequence of major, aftershocks or group shocks, and the aftershocks often occur shortly thereafter, it is desirable that the energy dissipater (also called a staged energy dissipation damper) preferably has multiple energy dissipation and shock absorption capabilities from a safety perspective.
Most of the existing metal energy dissipaters are single in structural shape and energy dissipation form, and cannot meet the requirements of small earthquakes and large earthquakes at the same time. For example, a part of the graded energy consumption dampers can consume energy under a large earthquake, but are in an elastic state under a small earthquake, and cannot play an energy consumption role; and the other part of the graded energy consumption damper can yield energy consumption under a small earthquake, but is easy to damage under a large earthquake, is insufficient to play the role of energy dissipation and shock absorption under the large earthquake, and cannot completely dissipate earthquake energy.
In summary, how to provide a staged energy dissipation damper capable of yielding and dissipating energy in stages under small, medium and large earthquakes becomes a problem to be solved urgently by those skilled in the art.

The invention aims to provide a hierarchical energy consumption damper which can meet the requirements of energy consumption and shock absorption of small earthquakes and energy consumption and shock absorption of medium earthquakes and large earthquakes.
In order to achieve the above object, the present invention provides a staged energy consumption damper, comprising two spaced substrates; a first yielding energy consumption piece and a second yielding energy consumption piece are arranged between the two substrates; two ends of the first yielding energy consumption part are respectively and fixedly connected with the two substrates; one end of the second yielding energy dissipation part is fixedly connected to one of the base plates, and the other end of the second yielding energy dissipation part is directionally and slidably connected to the other base plate.

Preferably, any one of the second energy dissipating metal plates is specifically an energy dissipating steel plate.
Preferably, the cross-sectional dimension of any of the second dissipative metal plates tapers from one end to the other; the middle plate is connected to one end of all the second energy dissipation metal plates with the smaller cross section.
Compared with the background technology, the graded energy consumption damper provided by the invention comprises two substrates which are distributed at intervals; a first yielding energy consumption piece and a second yielding energy consumption piece are arranged between the two substrates; two ends of the first yielding energy consumption part are respectively and fixedly connected with the two substrates; one end of the second yielding energy dissipation part is fixedly connected to one of the base plates, and the other end of the second yielding energy dissipation part is directionally and slidably connected to the other base plate.

The second yielding energy dissipating member thus consumes seismic energy in cooperation with the first yielding energy dissipating member. In short, the first yielding energy dissipating member and the second yielding energy dissipating member of the staged energy dissipating damper work together at medium and large earthquakes.

The invention provides a hierarchical energy consumption damper which comprises two base plates 1 distributed at intervals, and a first yielding energy consumption piece 2 and a second yielding energy consumption piece 3 which are arranged between the two base plates 1.
The two base plates 1 are used for connecting to-be-damped and anti-seismic construction facilities or sites, for example, the two base plates are fixed between supporting columns or embedded parts in the to-be-damped sites through fasteners such as bolts, and correspondingly, a plurality of connecting holes for bolts to penetrate through can be opened in any one of the base plates 1.
Two ends of the first yielding energy dissipation member 2 are respectively and fixedly connected with the two substrates 1, which is equivalent to a fixed beam between the two substrates 1. According to the materials of the first yielding energy dissipation member 2 and the base plate 1, the two end parts of the first yielding energy dissipation member 2 can be fixedly connected through welding, fastening piece locking, interference assembly and other modes.
The first end of the second yielding energy dissipation member 3 is fixedly connected to one of the base plates 1, and the second end of the second yielding energy dissipation member 3 is directionally and slidably connected to the other base plate 1.
Based on different connection relations between the first yielding energy dissipation member 2 and the second yielding energy dissipation member 3, small shock occurs outside and the outside acts on the first yielding energy dissipation member 2Exceeds the elastic limit σ of the first yielding energy dissipating component 2e1In the meantime, the first yielding energy dissipation member 2 yields and deforms, thereby dissipating energy of an external seismic source. At this time, because one end of the second yielding energy dissipation member 3 is directionally and slidably connected to the substrate 1, one end of the second yielding energy dissipation member 3 slides relative to the substrate 1, and the energy of an external seismic source is not enough to enable the second end of the second yielding energy dissipation member 3 to exceed the sliding constraint range of the substrate 1, the second yielding energy dissipation member 3 is in an elastic stage during a small earthquake, and at this time, the second yielding energy dissipation member 3 does not resist the external stress through bending deformation.
Along with the enhancement of the external vibration level, the relative displacement of the two base plates 1 is increased, the sliding range of the second end of the second yielding energy dissipation member 3 exceeds the constraint range of the base plates 1, at the moment, the two base plates 1 apply stress to the second yielding energy dissipation member 3 together, and the stress transmitted from the outside to the second yielding energy dissipation member 3 is larger than the elastic limit sigma of the second yielding energy dissipation member 3e2. That is to say, under the action of a medium earthquake and a large earthquake, the second yielding energy dissipation member 3 enters the yielding deformation stage in addition to the bending deformation of the first yielding energy dissipation member 2, and the energy of an external earthquake source is consumed through the bending deformation.
In summary, in the graded energy consumption damper, under the action of a small shock, the relative displacement generated by the two base plates 1 is small, the first yielding energy consumption piece 2 can only be bent and deformed to achieve the purpose of yielding energy consumption, and the second yielding energy consumption piece 3 is in an elastic state and does not have the functions of damping and dissipating energy. Therefore, the first yielding energy dissipation member 2 alone absorbs and dissipates energy in a small earthquake. Under the action of medium and large earthquakes, the two substrates 1 generate large relative displacement, and the second yielding energy dissipation part 3 begins to bend and deform so as to achieve the purpose of yielding energy dissipation. At this time, the second yielding energy dissipation member 3 consumes the seismic energy together with the first yielding energy dissipation member 2. Therefore, the graded energy consumption damper realizes graded yielding and has obvious graded yielding energy consumption effect.
The present invention provides a staged energy consumption damper, which is further described with reference to the accompanying drawings and embodiments.
On the basis of the above embodiments, one of the second yielding energy dissipation member 3 and the substrate 1 connected to the second yielding energy dissipation member 3 is provided with a linear sliding hole 4, and the other one is connected to a sliding pin 5 for penetrating the linear sliding hole 4.
In various embodiments of the present invention, a linear sliding hole 4 is disposed at an end of the second yielding energy dissipating member 3, and a sliding pin 5 is mounted on an inner surface of one of the base plates 1. The two substrates 1 are relatively displaced along the surface extension direction of any one substrate 1, the substrate 1 provided with the sliding pin shaft 5 slides relative to the end part of the second yielding energy dissipation part 3, the second yielding energy dissipation part 3 is prevented from yielding and deforming due to overlarge stress under the action of small shock, and further the grading energy dissipation damper cannot realize an obvious grading energy dissipation effect.
Under the action of small shock, one end of the second yielding energy dissipation member 3 slides back and forth relative to the base plate 1 under the matching relationship of the sliding pin shaft 5 and the linear sliding hole 4, so that the two base plates 1 are not enough to apply more than the elastic limit sigma to the second yielding energy dissipation member 3e2Of the stress of (c). The second yielding energy dissipating member 3 is therefore in this case in the elastic phase. During the action of medium and large earthquakes, the sliding displacement of the sliding pin shaft 5 in the linear sliding hole 4 reaches the limit of the linear sliding hole 4, and the stress applied by the two substrates 1 to the second yielding energy dissipation part 3 is greater than the elastic limit sigmae2The second yielding energy dissipation member 3 begins to generate bending deformation, and consumes seismic energy together with the first yielding energy dissipation member 2, so that the effect of obviously yielding in stages is achieved.
The two substrates 1 may be disposed in parallel, and the length direction of the linear sliding hole 4 may also be parallel to the surface of any one of the substrates 1, that is, the length direction of the linear sliding hole 4 is perpendicular to the normal of any one of the substrates 1. At this time, the sliding pin 5 slides along the length direction of the linear sliding under the relative displacement of the two substrates 1, so as to adjust the elastic limit σ of the second yielding energy dissipation component 3 by controlling the length of the linear sliding hole 4e2The corresponding source level.
The number and the length of the linear sliding holes 4 and the number and the length of the corresponding sliding pin shafts 5 can be specifically analyzed and set according to the requirements of parameters such as the shearing resistance, the strength and the like of the graded energy-consuming damper.
The number of the linear sliding holes 4 and the number of the sliding pin shafts 5 are both multiple, and obviously, the number of the linear sliding holes and the number of the sliding pin shafts are equal and the positions of the linear sliding holes and the positions of the sliding pin shafts are corresponding to each other.
As for the specific arrangement of the linear slide hole 4 and the slide pin 5, refer to fig. 1, in this example, a pair of parallel spaced wing plates 6 are vertically fixed on the inner surface of the base plate 1, and a gap with the same width is formed between the middle parts of the wing plates 6; the end of the second yielding energy dissipation member 3 is fixedly connected with a sliding plate 7, and the sliding plate 7 is inserted into and slidably connected with a gap formed by the pair of wing plates 6. Based on the above arrangement, all the linear sliding holes 4 are disposed on the sliding plate 7, and both ends of the sliding pin 5 are respectively fixedly connected to the pair of wing plates 6.
In this embodiment, the sliding pin 5 may specifically be a high-strength bolt with both ends fixed to the pair of wing plates 6. All the linear sliding holes 4 are distributed in a rectangular array in the sliding plate 7. Referring to fig. 2, an even number of the linear sliding holes 4 may be provided and arranged in parallel and symmetrically to the sliding plate 7.
The first yielding assembly comprises a plurality of first dissipative metal plates 21. All the first dissipative metal plates 21 can be connected vertically and equally spaced between the two substrates 1. Any adjacent first dissipative metal plates 21 are parallel. All the first dissipative metal plates 21 dissipate the energy transferred by the two substrates 1 at the small shock effect by bending deformation.
The specific number of the first energy dissipation metal plates 21 can be calculated according to the specific situations of the bearing capacity, the energy dissipation situation and the like of the first yielding energy dissipation member 2 in the engineering example.
For example, the first energy dissipating metal plate 21 may be provided as an X-shaped, diamond-shaped, or U-shaped steel plate. Based on the connection relationship between the first dissipative metal plate 21 and the two substrates 1, the cross-sectional dimension of both ends of any one of the first dissipative metal plates 21 is larger than the cross-sectional dimension of the middle portion. Referring to fig. 4, fig. 4 is a schematic structural diagram of the first energy dissipation metal plate 21 according to the embodiment of the present invention. The cross section of the first energy dissipation metal plate 21 at any height along the longitudinal direction is rectangular, and the thickness of the first energy dissipation metal plate 21 is the width of the rectangle, so that the length of the cross section of the two ends of the first energy dissipation metal plate 21 is greater than the length of the cross section of the middle part of the first energy dissipation metal plate 21. This structure is adapted to the stress distribution of the first dissipative metal sheet 21, which is beneficial to improving the yield dissipative effect of the first dissipative metal sheet 21.
Similarly, the second yielding energy dissipating member 3 may also include a plurality of second energy dissipating metal plates 31; the top ends of all the second dissipative metal plates 31 are fixedly connected by the intermediate plate 8. Similarly, the specific number of the second dissipative metal plates 31 can be calculated according to the specific situations of the bearing capacity and the dissipative situation of the second yielding dissipative element 3 in the engineering example.
For the second yielding energy dissipation member 3 with the linear sliding hole 4 at the end, the ends at the same side of the plurality of second energy dissipation metal plates 31 can be fixedly connected through the horizontally arranged middle plate 8, and then the linear sliding hole 4 is arranged or the sliding plate 7 with the linear sliding hole 4 is arranged.
Any one of the second dissipative metal plates 31 is specifically configured as a dissipative steel plate. Similarly, the first dissipative metal plate 21 according to the above embodiments can be made of a rigid material.
To achieve better technical effects, referring to fig. 1 and 5, the cross-sectional dimension of any one of the second dissipative metal plates 31 is tapered from one end to the other end, and the middle plate 8 is connected to the end of the whole second dissipative metal plate 31 having a smaller cross-section.
The graded energy consumption damper as a prefabricated whole can be conveniently and quickly integrally applied to engineering examples, such as being installed in a frame supporting structure of a shock absorption building or in a concrete embedded part. In case of small earthquake, the plurality of second energy consumption metal plates 31 realize relative sliding with the substrate 1 through the linear sliding holes 4 and the sliding pin shafts 5, so that all the second energy consumption metal plates 31 are in an elastic stage at the moment, and only the plurality of first energy consumption metal plates 21 consume earthquake energy; during a heavy earthquake, the sliding range of the second energy consumption plates exceeds the constraint range of the linear sliding holes 4 and the sliding pin shafts 5, so that the second energy consumption plates enter a yielding stage, consume earthquake energy together with the first energy consumption metal plates 21, and achieve the effect of obvious staged yielding.
The present invention provides a stepped energy dissipation damper as described above in detail. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
