Description

[Technical Field]

[0001] The present invention relates to a shock-damping wall, and more particularly to a composite damping shock-damping wall. [Previous Technology]

[0002] In response to the increasing demand for seismic isolation in buildings, the performance requirements for seismic dampers in engineering are also gradually increasing.

[0003] However, the manufacturing process of traditional steel panel dampers (SPDs) requires multiple welding points, which is time-consuming, and the overall size of the unit is large, making it difficult to carry out replacement projects and maintain. When the space of the building itself is limited, it is difficult to design a product that meets the requirements of traditional steel panel dampers. [Summary of the Invention]

[0004] The present invention provides a composite damping shock-absorbing wall that has a wider range of design flexibility in terms of stiffness, damping force, and toughness capacity.

[0005] The composite damping seismic wall of the present invention is suitable for installation between a first component and a second component of a building. The composite damping seismic wall includes a wall body. The wall body includes a first metal plate, a plurality of second metal plates, and an elastic portion. The first metal plate has opposing first and second surfaces and a plurality of first openings extending from the first surface through the first metal plate to the second surface. The plurality of second metal plates are respectively disposed in these first openings. The elastic portion covers the first metal plate and the second metal plates, wherein the material of the first metal plate is different from the material of the second metal plates.

[0006] In one embodiment of the present invention, the first metal plate has opposing first and second sides, and the second metal plates are located between the first and second sides and are spaced apart along a first direction.

[0007] In one embodiment of the present invention, each of the above-mentioned second metal plates has a first end and a second end opposite to each other, the first end being not connected to a first side and the second end being not connected to a second side.

[0008] In one embodiment of the present invention, the first metal plate further has a plurality of second openings and a plurality of third openings extending from the first surface through the first metal plate to the second surface. The second openings are located on the first side, the third openings are located on the second side, and the second openings and the third openings are respectively arranged along a first direction.

[0009] In one embodiment of the present invention, each of the second openings and each of the third openings correspond to each other in a second direction perpendicular to the first direction, and a first opening corresponds between adjacent second openings.

[0010] In one embodiment of the present invention, the second opening and the third opening described above are provided with elastic portions.

[0011] In one embodiment of the present invention, each of the above-mentioned second metal plates includes a first plate and a second plate, and each first opening has a first portion and a second portion to respectively accommodate the first plate and the second plate, the first portion and the first plate extending to a first side, and the second portion and the second plate extending to a second side.

[0012] In one embodiment of the present invention, the first metal plate described above has a third side and a fourth side opposite to each other, the third side and the fourth side being a plane or a curved surface.

[0013] In one embodiment of the present invention, each of the above-mentioned second metal plates protrudes or is recessed on the first surface and the second surface.

[0014] In one embodiment of the present invention, the area ratio of the plurality of second metal plates to the first metal plate is between 0.8 and 5 times.

[0015] Based on the above, in the composite damping seismic wall of the present invention, the wall body is made of an elastic portion covering a first metal plate and multiple second metal plates, and the material of the first metal plate is different from the material of each of the second metal plates. In the case of small earthquakes, it can provide additional stiffness and strength to the structure. Under the action of a large earthquake, the upper and lower connecting plates will misalign and move, causing the first metal plate to deform and enter a yielding energy dissipation state, while the second metal plates located within the first metal plate will also be deformed by the first metal plate and also enter a yielding energy dissipation state. Therefore, the composite damping seismic wall can have a wider range of design flexibility in terms of stiffness, damping force, and toughness capacity.

[0016] In order to make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below, and detailed descriptions are given in conjunction with the accompanying drawings.

Implementation Method

[0017] Figure 1 is a schematic diagram of a composite damping seismic wall according to an embodiment of the present invention applied to a building. Referring to Figure 1, the composite damping seismic wall 100 of this embodiment is suitable for being disposed between a first component 10 and a second component 20 of a building, with the second component 20 opposite to the first component 10. In one embodiment, the first component 10 includes an upper crossbeam 11 and an upper base 12, and the second component 20 includes a lower crossbeam 21 and a lower base 22. The first component 10 and the second component 20 are, for example, reinforced concrete (RC) structures or steel structures, and the present invention does not limit them to this. In one embodiment, when an earthquake or wind occurs, the composite damping seismic wall 100 is used to reduce the structural response under the action of seismic force or wind force, thereby improving the wind resistance and earthquake resistance of the building.

[0018] In this embodiment, the composite damping shock-absorbing wall 100 includes a wall body 110, and is connected to the first component 10 and the second component 20 via a first fixing member 140 and a second fixing member 150, respectively. In this embodiment, the first fixing member 140 and the second fixing member 150 are multiple bolts, but the present invention is not limited thereto. In this way, in maintenance situations, only the first fixing member 140 and the second fixing member 150 need to be removed, which is extremely convenient.

[0019] The following describes the structure of the composite damping seismic isolation wall.

[0020] Figure 2A is a perspective view of a composite damping seismic isolation wall according to an embodiment of the present invention. Figure 2B is a front view of the composite damping seismic isolation wall of Figure 2A. Figure 2C is a side view of the composite damping seismic isolation wall of Figure 2A.

[0021] Please refer to Figures 2A to 2C. In this embodiment, the wall 110 includes a first metal plate 111, a plurality of second metal plates 112, and an elastic portion 113. It should be noted that the elastic portion in Figures 2A to 2C is drawn with dashed lines to clearly illustrate its internal components.

[0022] In this embodiment, the first metal plate 111 has opposing first surfaces F1 and second surfaces F2, and a plurality of first openings A1 extending from the first surface F1 through the first metal plate 111 to the second surface F2. Second metal plates 112 are respectively disposed in the first openings A1. For example, the second metal plates 112 are embedded in the first metal plate 111, but the present invention is not limited thereto.

[0023] In this embodiment, the number of second metal plates 112 is the same as the number of first openings A1. Three second metal plates 112 are schematically shown in the figure. However, in other embodiments, the number of second metal plates can be appropriately adjusted according to engineering needs. This invention does not limit this.

[0024] In this embodiment, the elastic portion 113 covers the first metal plate 111 and the second metal plate 112. For example, the elastic portion 113 is made of high-damping rubber, but the present invention is not limited thereto. In other embodiments, the elastic portion may also be made of a polymer coarse material, and the present invention is not limited thereto. The advantage of this design is that it can provide additional stiffness and strength to the structure in the event of a small earthquake.

[0025] In this embodiment, the material of the first metal plate 111 is different from the material of each of the second metal plates 112. For example, the first metal plate 111 is a steel plate, and the second metal plate 112 is a lead plate, but the present invention is not limited thereto. In some embodiments, the ratio of the total area of ​​the plurality of second metal plates 112 to the total area of ​​the first metal plate 111 is about 0.8 to 5 times, but the present invention is not limited thereto. In this embodiment, the advantage of using lead as the material of the second metal plate 112 is that lead has a low yield point and recrystallization properties, and compared with steel, it is not easily damaged by fatigue loads, thus providing better energy dissipation behavior.

[0026] In this embodiment, the elastic portion 113 covers the first metal plate 111 and a plurality of second metal plates 112 to form a single-piece composite damping seismic wall 100, and its manufacturing process is simple. Specifically, both the first metal plate 111 and the second metal plates 112 are one-piece pieces. The first metal plate 111 and the second metal plates 112 are cut and assembled, and then integrally vulcanized with the elastic portion 113 to complete the manufacturing process. In other embodiments, the composite damping seismic wall can also be manufactured in other suitable ways; as long as an elastomer is used to cover the composite metal plate, it falls within the scope of protection of this invention.

[0027] In some embodiments, since the first metal plate 111 and the second metal plate 112 are both thin sheets, the composite damping shock-absorbing wall 100 can be used when the width of the first component 10 and the second component 20 is relatively limited. For example, the width of the composite damping shock-absorbing wall can be made within 15 to 25 cm, but the present invention is not limited thereto.

[0028] In this embodiment, the first metal plate 111 has a first side S1 and a second side S2, the first side S1 being adapted to correspond to the first component 10 in FIG. 1, and the second side S2 being adapted to correspond to the second component 20 in FIG. 1. Specifically, the composite damping seismic wall 100 also includes an upper connecting plate 120 and a lower connecting plate 130. The upper connecting plate 120 and the lower connecting plate 130 are steel plates, but the present invention is not limited thereto. It should be noted that the upper connecting plate 120 and the lower connecting plate 130 in FIG. 2A to FIG. 2C are only schematically illustrated and are adapted to be connected to the first component 10 and the second component 20 in FIG. 1, respectively. The actual size ratio of the upper connecting plate 120 and the lower connecting plate 130 can be appropriately adjusted according to engineering needs, and the present invention does not limit this.

[0029] In this embodiment, the strength of the upper connecting plate 120 and the lower connecting plate 130 is greater than the strength of the first metal plate 111, and the thickness W2 of the upper connecting plate 120 and the lower connecting plate 130 is greater than the thickness W3 of the wall 110. The wall 110 as a whole serves as the core energy dissipation section and is suitable for shear yielding to dissipate energy. The shear strength is controlled by the energy dissipation section, but the present invention is not limited thereto.

[0030] Under the above configuration, under the action of a major earthquake, the upper connecting plate 120 and the lower connecting plate 130 will be misaligned and moved, causing the first metal plate 111 to deform and enter the yielding and energy dissipation. The second metal plate 112 located inside the first metal plate 111 will also be deformed by the first metal plate 111 and enter the yielding and energy dissipation. Since the second metal plate 112 is made of lead, it has the characteristics of low yielding point and high toughness capacity.

[0031] In one embodiment, since the first metal plate 111 and the second metal plate 112 are completely covered by the elastic part 113, the first metal plate 111 and the second metal plate 112 can be provided with a confinement effect and recovery stiffness, while also providing some damping force, so that the first metal plate 111 and the second metal plate 112 do not produce out-of-plane buckling, so as to more stably exert the toughness capacity.

[0032] In detail, in this embodiment, the second metal plates 112 are arranged at intervals along the first direction N1, but the present invention is not limited thereto. In this embodiment, the second metal plates 112 are arranged at equal intervals, but the present invention is not limited thereto.

[0033] Furthermore, in this embodiment, each second metal plate 112 has a first end E1 and a second end E2, the first end E1 facing the first side S1 but not connected to the first side S1, and the second end E2 facing the second side S2 but not connected to the second side S2. In the first direction N1, there is a first distance D1 between each second metal plate 112, and in the second direction N2 perpendicular to the first direction N1, there is a second distance D2 between each first end E1 and the first side S1. The second distance D2 is greater than the first distance D1, but the present invention is not limited thereto.

[0034] In this embodiment, the outer contour of the first opening A1 is the same as the outer contour of the second metal plate 112. In other words, the second metal plate 112 completely fills the first opening A1. Furthermore, referring to FIG2A, in this embodiment, the surface of the second metal plate 112 is flush with the first surface F1 and the second surface F2. That is, the second metal plate 112 has the same thickness as the first metal plate 111. However, in other embodiments, the thickness of the second metal plate 112 can be appropriately adjusted according to actual needs, and the present invention is not limited thereto.

[0035] In this embodiment, the shape of the second metal plate 112 is, for example, elliptical or rugby ball-shaped. Specifically, the minor axis L1 of the second metal plate 112 is parallel to the first direction N1, and the major axis L2 is parallel to the second direction N2. However, in other embodiments, the second metal plate 112 may also be circular, rectangular or triangular, etc., which can be appropriately adjusted according to actual needs. This invention is not limited thereto.

[0036] In some embodiments, the height of the second metal plate 112 in the second direction N2 is greater than the width of the second metal plate 112 in the first direction N1, but the present invention is not limited thereto.

[0037] In this embodiment, the first metal plate 111 has a third side S3 and a fourth side S4, which are curved surfaces. Specifically, both the third side S3 and the fourth side S4 are designed to be concave towards the center of the first metal plate 111. However, in other embodiments, the shape and thickness of the first metal plate 111 can be appropriately adjusted according to actual needs, and the present invention is not limited thereto.

[0038] Other embodiments will be listed below for illustration. It should be noted that the following embodiments use the component reference numerals and some content of the foregoing embodiments, wherein the same reference numerals are used to represent the same or similar components, and the description of the same technical content is omitted. For the description of the omitted parts, please refer to the foregoing embodiments, and the following embodiments will not repeat them.

[0039] Figures 3 and 4 are perspective views of the composite damping seismic wall according to several embodiments of the present invention. It should be noted that the elastic parts in Figures 3 and 4 are drawn with dashed lines to clearly show their internal components. Please refer to Figure 3 first. In this embodiment, the composite damping seismic wall 100B is slightly different from the composite damping seismic wall 100 in Figure 2A. The main difference is that the second metal plate 112B of the wall 110B protrudes from the first surface F1 and the second surface F2, which is suitable for design requirements that require higher damping and increases the damping output of the second metal plate 112B. However, the present invention is not limited thereto.

[0040] In this embodiment, the elastic part 113B completely covers the first metal plate 111B and the second metal plate 112B, which can provide the first metal plate 111B and the second metal plate 112B with a confinement effect and restoring stiffness, while also providing some damping force, so that the first metal plate 111B and the second metal plate 112B do not produce out-of-plane buckling, so as to more stably exert the toughness capacity.

[0041] Please refer to Figure 4. In this embodiment, the composite damping seismic wall 100C is slightly different from the composite damping seismic wall 100 in Figure 2A. The main difference is that the second metal plate 112C of the wall 110C is recessed between the first surface F1 and the second surface F2. This is suitable for designs requiring lower damping, reducing the damping output of the second metal plate 112C, but the present invention is not limited thereto.

[0042] In this embodiment, the elastic part 113C completely covers the first metal plate 111C and the second metal plate 112C, which can provide the first metal plate 111C and the second metal plate 112C with a confinement effect and restoring stiffness, while also providing some damping force, so that the first metal plate 111C and the second metal plate 112C do not produce out-of-plane buckling, so as to more stably exert the toughness capacity.

[0043] In this embodiment, the first metal plate 111C of the wall 110C also has a plurality of second openings A2 and a plurality of third openings A3. The second openings A2 and the third openings A3 extend from the first surface F1 through the first metal plate 111C to the second surface F2. The second openings A2 are located on the first side S1, and the third openings A3 are located on the second side S2. The second openings A2 and the third openings A3 are arranged along the first direction N1, and the first opening A1 is located between the second openings A2 and the third openings A3, but the present invention is not limited thereto. In this embodiment, a third metal plate 112C' is embedded in the plurality of second openings A2 and the plurality of third openings A3. The third metal plate 112C' is a lead plate. Lead has a low yield point and recrystallization properties. Compared with steel, it is not easily damaged by fatigue load and can provide better energy dissipation behavior.

[0044] Figure 5A is a perspective view of a composite damping seismic wall according to an embodiment of the present invention. Figure 5B is a front view of the composite damping seismic wall of Figure 5A. Referring to Figures 5A and 5B, in this embodiment, the composite damping seismic wall 100D is slightly different from the composite damping seismic wall 100 of Figure 2A. The main difference is that the first metal plate 111D of the wall 110D also has a plurality of second openings A2 and a plurality of third openings A3. The second openings A2 and third openings A3 extend from the first surface F1 through the first metal plate 111D to the second surface F2. The second openings A2 are located on the first side S1, and the third openings A3 are located on the second side S2. The second openings A2 and third openings A3 are arranged along the first direction N1, and the first opening A1 is located between the second openings A2 and the third openings A3. However, the present invention is not limited thereto.

[0045] In this embodiment, each second opening A2 and each third opening A3 corresponds to each other in a second direction N2 perpendicular to the first direction N1. That is, the second opening A2 and the third opening A3 are aligned with each other, but the present invention is not limited thereto. In this embodiment, a first opening A1 is provided between adjacent second openings A2. That is, the second openings A2 and the third openings A3 are symmetrically arranged on the upper and lower sides of the second metal plate 112D, and are offset from the first opening A1 in the second direction N2, but the present invention is not limited thereto.

[0046] In this embodiment, the second opening A2 and the third opening A3 are provided with elastic portions 113D. That is, the elastic portions 113D completely cover and fill the second opening A2 and the third opening A3, but the present invention is not limited thereto.

[0047] Figure 6A is a perspective view of a composite damping seismic wall according to an embodiment of the present invention. Figure 6B is a front view of the composite damping seismic wall of Figure 6A. Referring to Figures 6A and 6B, in this embodiment, the composite damping seismic wall 100E is slightly different from the composite damping seismic wall 100 of Figure 2A. The main difference is that each of the second metal plates 112E of the wall 110E includes a first plate 1121 and a second plate 1122, which are independent of each other. Each first opening A1' has a first portion A11 and a second portion A12, which are independent of each other to accommodate the first plate 1121 and the second plate 1122 respectively. In this embodiment, the first plate 1121 and the second plate 1122 have the same shape, for example, a rectangle, but the present invention is not limited thereto.

[0048] In this embodiment, the first plate 1121 and the first portion A11 extend to the first side S1 of the first metal plate 111E, and the second plate 1122 and the second portion A12 extend to the second side S2 of the first metal plate 111E.

[0049] Referring to FIG6B, in the first direction N1, there is a first gap G1 between each first portion A11. In the second direction N2, there is a second gap G2 between each first portion A11 and each second portion A12. The second gap G2 is larger than the first gap G1, but the present invention is not limited thereto.

[0050] In some embodiments, in the second direction N2, the height M1 of the second metal plate 112E is greater than the width M2 of the second metal plate 112E. In the first direction N1, the width M2 of each second metal plate 112E is approximately 3 to 5 times the first gap G1, but the present invention is not limited thereto.

[0051] In summary, in the composite damping seismic wall of the present invention, an elastic portion is used to cover a first metal plate and multiple second metal plates, and the material of the first metal plate is different from the material of each of the second metal plates. Since the first and second metal plates are completely covered by the elastic portion, they can provide a confinement effect and restoring stiffness, while also providing partial damping force, preventing out-of-plane buckling and thus more stably utilizing their ductile capacity. In the case of small earthquakes, it can provide additional stiffness and strength to the structure. Under the action of a large earthquake, the upper and lower connecting plates will misalign, causing the first metal plate to deform and enter a yielding energy dissipation state. The second metal plates located within the first metal plate will also be deformed by the first metal plate and enter a yielding energy dissipation state. In one embodiment, the first metal plate is a steel plate, and the second metal plate is a lead plate. Lead has a low yield point and recrystallization properties, and compared to steel, it is less prone to failure due to fatigue loads, thus providing better energy dissipation behavior. This allows composite damping seismic walls to have a wider range of design flexibility in terms of stiffness, damping force, and toughness capacity.

[0052] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims. [Simplified Explanation of the Diagram]
