Description

Technical Field

[0001] The invention relates to the technical field of earthquake prevention and disaster reduction, and more specifically to a modular graded energy dissipation damper for resisting wind vibration, small earthquake, medium earthquake, large earthquake and huge earthquake. Background Art

[0002] For high-rise buildings and super high-rise buildings, under the action of wind loads, simply reducing wind-induced vibration by increasing the mass of the structure itself will often greatly increase the economic cost and the vibration reduction effect is not obvious. Therefore, many energy dissipation and vibration absorbers mainly for wind resistance have been used in the engineering field. Among them, the tuned mass damper is widely known and relatively mature. In recent years, viscoelastic dampers have also been well developed in the field of wind resistance design.

[0003] In order to achieve the purpose of effective energy dissipation of the damper under different earthquake levels and improve the economy and safety, multi-level graded yield dampers have been widely studied and applied in recent years. For example, the utility model patent with the authorization announcement number CN221545989 U previously applied by the applicant discloses a graded yield damper that can resist small earthquakes, medium earthquakes, large earthquakes and huge earthquakes, including a lower base plate and an upper base plate distributed at intervals, a first yield energy dissipation member is installed between the lower base plate and the upper base plate, and a second yield energy dissipation member, a third yield energy dissipation member and a fourth yield energy dissipation member are installed between the lower base plate and the baffle; the first yield energy dissipation member includes at least two first energy dissipation metal plates arranged in parallel, and the upper and lower ends of the first yield energy dissipation member, the third yield energy dissipation member and the fourth yield energy dissipation member are respectively extended into the sawtooth groove of the baffle, and a gap is provided between the inner wall of the sawtooth groove. The utility model realizes the staged yielding according to the earthquake source level, achieves the effect of obvious staged yielding, and meets the purpose of multi-level energy dissipation and shock reduction.

[0004] However, the above patented technology still has problems such as unclear yield point, inability to play the role of energy consumption under the action of wind, and complex structure.

[0005] Therefore, how to provide a graded energy dissipation damper that can coordinate various situations such as wind vibration, small earthquake, medium earthquake, large earthquake and huge earthquake is a problem that technical personnel in this field urgently need to solve.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See attached Figure 1 and attached Figure 2 The embodiment of the present invention discloses a modular graded energy dissipation damper for resisting wind vibration and small, medium, large and huge earthquakes, including an upper base plate 1 and a lower base plate 2, between which small earthquake energy absorption components 3, medium earthquake energy absorption components 4, large earthquake energy absorption components 5 and huge earthquake energy absorption components 6 are arranged in sequence from both ends to the middle; it also includes: a wind vibration energy absorption component 10 arranged between the upper base plate 1 and the lower base plate 2 and located on both sides of each energy absorption component; the wind vibration energy absorption component 10 includes two outer plates 8 and inner plates 9 arranged at intervals and connected to the upper base plate 1 and the lower base plate 2 respectively, and a viscoelastic layer 7 is connected between the corresponding overlapping surfaces of the outer plate 8 and the inner plate 9.

[0033] In this embodiment, the wind vibration energy absorbing component 10 connects the outer plate 8 to the upper base plate 1 and the inner plate 9 to the lower base plate 2 by bolts 12. A layer of viscoelastic material is connected to the middle part where the outer plate 8 and the inner plate 9 overlap. Under the action of wind vibration, the outer plate 8 and the inner plate 9 are relatively displaced, and the viscoelastic material deforms to dissipate energy. The area and thickness of the viscoelastic layer can be adjusted by adjusting the overlapping area and thickness of the outer plate 8 and the inner plate 9.

[0034] See attached Figure 3 , the small earthquake energy dissipation component 3 includes two X-shaped plates connected between the upper base plate 1 and the lower base plate 2 and located at both ends. Specifically: the small earthquake energy dissipation component 3 is an X-shaped plate with an upper and a lower base plate, and a screw hole 14 is left on the base plate, which is connected to the upper base plate 1 and the lower base plate 2 by bolts 12. When a small earthquake occurs, the upper base plate 1 and the lower base plate 2 produce a small relative displacement, and the small earthquake energy dissipation component 3 is deformed to yield energy dissipation.

[0035] In order to further optimize the above technical solution, a baffle 11 is fixed to the bottom surface of the upper substrate 1 along its length direction, and the baffle 11 is located between the two X-shaped plates. In the present embodiment, the baffle 11 is welded at the middle part along the length direction of the upper substrate 1, and a plurality of positioning grooves are provided on the bottom edge of the baffle 11 along its length direction. The widths of the plurality of positioning grooves gradually increase from the two ends of the baffle 11 to the middle, and the positioning grooves of different widths correspond to the medium-seismic energy-absorbing component 4, the large-seismic energy-absorbing component 5 and the huge-seismic energy-absorbing component 6, respectively.

[0036] See attached Figure 4 The medium-shock energy-absorbing component 4, the large-shock energy-absorbing component 5 and the huge-shock energy-absorbing component 6 all include a triangular plate, the bottom edge of the triangular plate is connected to the lower base plate 2, the top end of the triangular plate is located in the positioning groove, and there is a movable gap between the two sides of the positioning groove, and the gap between the triangular plate and the positioning groove of the medium-shock energy-absorbing component 4, the large-shock energy-absorbing component 5 and the huge-shock energy-absorbing component 6 increases successively.

[0037] Specifically, the medium-earthquake energy-absorbing component 4, the large-earthquake energy-absorbing component 5, and the huge-earthquake energy-absorbing component 6 are triangular plates with a lower base, on which screw holes 14 are left, and which are connected to the lower base plate 2 by bolts 12; the upper end of the triangular plate is a free end, which is placed in the middle of the positioning groove of the baffle 11, and a certain gap is left with the side wall of the positioning groove. The gap length of the positioning groove determines the displacement size of each energy-absorbing component that causes deformation. The top of the huge-earthquake energy-absorbing component 6 has the largest gap from the groove, followed by the large-earthquake energy-absorbing component 5, and the medium-earthquake energy-absorbing component 4 has the smallest gap; during a medium earthquake, , the small earthquake yielding component 3 yields first, the top of the medium earthquake energy absorbing component 4 begins to contact the side wall of the positioning groove and produces deformation yield energy consumption, the large earthquake energy absorbing component 5 and the huge earthquake energy absorbing component 6 do not contact the groove wall and do not participate in energy consumption; during a large earthquake, the small earthquake energy absorbing component 3 and the medium earthquake energy absorbing component 4 yield one by one, and the large earthquake energy absorbing component 5 contacts the groove wall and yields energy consumption; during a huge earthquake, the small earthquake energy absorbing component 3, the medium earthquake energy absorbing component 4 and the large earthquake energy absorbing component 5 yield one by one, and the huge earthquake energy absorbing component 6 contacts the groove wall and yields energy consumption, thereby realizing graded energy dissipation.

[0038] In this embodiment, the length of the positioning groove can be determined according to earthquake resistance requirements.

[0039] Each energy-consuming component is connected to the upper base plate 1 and the lower base plate 2 by bolts 12 and is an independent module respectively, thereby realizing modularization.

[0040] In order to further optimize the above technical solution, the number of X-shaped plates is two, and the number of triangular plates of the medium-seismic energy absorption component 4, the large-seismic energy absorption component 5 and the huge-seismic energy absorption component 6 are all two.

[0041] In this embodiment, the energy-absorbing components are arranged symmetrically on the left and right, and the wind-vibration energy-absorbing components 10 are installed in front of and behind the damper.

[0042] In this embodiment, the shape of the middle portion of the X-shaped plate and the upper portion of the triangular plate in each energy-consuming component is a smooth curve transition to prevent stress concentration.

[0043] See attached Figure 5 The top edge of the outer plate 8 is connected to the upper base plate 1 , and the bottom edge of the inner plate 9 is connected to the lower base plate 2 .

[0044] In order to further optimize the above technical solution, two spacers 13 are symmetrically fixed to the top surface of the upper substrate 1 and the bottom surface of the lower substrate 2 along the length direction.

[0045] See attached Figure 2 The two pads 13 on the upper base plate 1 are located on the inner sides of the two outer plates 8 , and the two pads 13 on the lower base plate 2 are located on the outer sides of the two inner plates 9 .

[0046] In order to further optimize the above technical solution, a notch is opened on the cushion block 13 and the cushion block 13 is welded and fixed to the upper base plate 1 and the lower base plate 2 .

[0047] See attached Figure 6 The upper base plate 1 and the lower base plate 2 are provided with a plurality of screw holes 14 for connecting various energy-absorbing components, and the bolts 12 are connected through the screw holes 14. Specifically, two rows of screw holes 14 are respectively reserved on the outer side of the pad 13 on the upper base plate 1 and the inner side of the pad 13 on the lower base plate 1 for connecting the outer side plate 8 and the inner side plate 9 of the wind vibration energy-absorbing component 10.

[0048] In this embodiment, the upper base plate 1, the lower base plate 2, the inner plate 9 and the outer plate 8 of the wind vibration energy absorption component 10, the small earthquake energy absorption component 3, the medium earthquake energy absorption component 4, the large earthquake energy absorption component 5, the huge earthquake energy absorption component 6, the baffle 11, and the pad 13 can be made of Q235 steel.

[0049] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
