Description

[Technical Field]

[0001] The present invention relates to a plate-mounted steel damper, and more particularly to a plate-mounted steel damper that is installed in a building component and is easy to manufacture. [Background technology]

[0002] In recent years, seismic isolation, vibration control, and earthquake resistance technologies for various buildings have been continuously developed. Generally, in order for building structures to have sufficient strength against horizontal external forces caused by earthquakes and wind, it is usually necessary to install vibration control energy dissipation devices. The principle of these vibration control energy dissipation devices is mainly to absorb and dissipate energy, reduce structural deformation under the action of external forces, and even prevent structural collapse.

[0003] A steel plate damper-equipped frame (SPD-MRF) is a type of metal-yielding seismic control frame. This frame adds steel plate dampers to a conventional bending-resistant frame, improving the system's stiffness, strength, toughness, and energy dissipation capacity. Steel plate dampers are also a type of shear-yielding seismic stud. Conventional steel plate dampers include an elastic section and an energy-dissipating section. The elastic section uses standard steel, while the energy-dissipating section uses low-yield-strength steel (LYP steel). However, low-yield-strength steel is expensive and complex to install. Therefore, there is currently a need for a seismic control system that is easy to manufacture, can be installed quickly, is inexpensive, and can significantly improve the seismic capacity of buildings.

For example, a component or structure comprising multiple elements is not limited to only the elements listed herein, but may include other elements not expressly listed but inherent to the component or structure.

[0019] 1 is a manufacturing flow chart of the plate-mounted steel damper of the present invention. As shown in FIG. 1, the manufacturing process of the plate-mounted steel damper of the present invention includes the following steps:

[0020] Step S1: Provide H-shaped steel material A.

[0021] The following description will be made with reference to Figures 1 and 2. Figure 2 is a schematic diagram of cutting an H-shaped steel material A along a first plane P1 and a second plane P2 perpendicular to a first direction D1 during the manufacturing process of the plate-mounted steel damper of the present invention. As shown in Figures 1 and 2, the present invention first provides an H-shaped steel material A. The H-shaped steel material A has a length, width, and height. The length of the H-shaped steel material A extends along the first direction D1. The width of the H-shaped steel material A extends along the second direction D2. The height of the H-shaped steel material A extends along the third direction D3. Any two directions among the first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other.

[0022] Step S2: The H-shaped steel material A is cut along a first plane P1 and a second plane P2 perpendicular to the first direction D1. This cutting forms a main structure A1, a first sub-structure A2, and a second sub-structure A3 from the H-shaped steel material A. The first sub-structure A2 and the second sub-structure A3 have the same dimensions. The main structure A1 includes a first structural part 1, a second structural part 2, and a third structural part 3. The third structural part 3 is located between the first structural part 1 and the second structural part 2.

[0023] Referring to Figures 1 to 3, Figure 3 is a schematic diagram of the H-shaped steel material A after cutting. As shown in Figures 1 to 3, after providing the H-shaped steel material A in step S1, the present invention cuts the H-shaped steel material A along different planes perpendicular to the first direction D1. As shown in Figures 2, the H-shaped steel material A is cut along a first plane P1 and a second plane P2, respectively, to form the H-shaped steel material A into a main structure A1, a first sub-structure A2, and a second sub-structure A3. The first sub-structure A2 and the second sub-structure A3 have the same dimensions, including the same length, width, height, and structural outer shape. In the present invention, the length of the main structure A1 in the first direction D1 is greater than the lengths of the first sub-structure A2 and the second sub-structure A3 in the first direction D1. That is, the main structure A1 formed after cutting is a longer H-shaped steel material, while the first sub-structure A2 and the second sub-structure A3 formed after cutting are relatively shorter H-shaped steel materials.

[0024] The main structure A1 includes a first structural portion 1, a second structural portion 2, and a third structural portion 3. The third structural portion 3 is located between the first structural portion 1 and the second structural portion 2. The first structural portion 1 includes a first web plate 11 and two first flanges 12. The two first flanges 12 are connected to both side edges of the first web plate 11 symmetrically and perpendicularly. Each first flange 12 has an opposing first exposed surface 121 and a first connecting surface 122. The first connecting surfaces 122 of each first flange 12 are connected to corresponding side edges of the first web plate 11. The second structural portion 2 includes a second web plate 21 and two second flanges 22. The two second flanges 22 are connected to both side edges of the second web plate 21 symmetrically and perpendicularly. The second web plate 21 has two opposing second installation surfaces 211. Each second flange 22 has an opposing second exposed surface 221 and a second connecting surface 222. The second connecting surface 222 of each second flange 22 is connected to a corresponding side edge of the second web plate 21. The second exposed surface 221 of each second flange 22 faces outward. The third structural portion 3 includes a third web plate 31 and two third flanges 32. The two third flanges 32 are connected to both side edges of the third web plate 31 symmetrically and perpendicularly. The third web plate 31 has two opposing third installation surfaces 311.

[0025] In this embodiment of the present invention, the H-shaped steel material A is cut at the predetermined first plane P1 and second plane P2. As a result of this cutting, the length of the first sub-structure A2 in the first direction D1 is shorter than the lengths of the first web plate 11 and the first flange 12 in the same direction. Similarly, the length of the second sub-structure A3 in the first direction D1 is shorter than the lengths of the second web plate 21 and the second flange 22 in the same direction. This dimensional arrangement facilitates the subsequent welding, fixing, and assembly of the plate parts.

[0026] Step S3: The first sub-structure A2 and the second sub-structure A3 are cut along a third plane P3 and a fourth plane P4, respectively, perpendicular to the second direction D2. This cutting results in a first cover plate 4 and two first side plates 5 being formed from the first sub-structure A2. These two first side plates 5 have the same dimensions. Similarly, a second cover plate 6 and two second side plates 7 are formed from the second sub-structure A3. These two second side plates 7 have the same dimensions.

[0027] Referring to Figures 1 to 5, Figure 4 is a schematic diagram of the manufacturing process for the plate-mounted steel damper of the present invention, in which the first sub-structure A2 and the second sub-structure A3 are cut along the third plane P3 and the fourth plane P4 perpendicular to the second direction D2. Figure 5 is a schematic diagram of the first sub-structure A2 and the second sub-structure A3 after cutting. As shown in Figures 1 to 5, after cutting the H-shaped steel material A in step S2, the present invention cuts the first sub-structure A2 and the second sub-structure A3 along different planes perpendicular to the second direction D2. For example, as shown in Figure 4, the first sub-structure A2 is cut along the third plane P3 to form a first cover plate 4 and two first side plates 5. These two first side plates 5 have the same length, width, height, and structural outer shape. The first cover plate 4 has two opposing first surfaces 41. Each first side plate 5 has an opposing first flat surface 51 and a first cut surface 52. After the first sub-structure A2 is cut into the first cover plates 4, a protruding structure exists on the first cut surface 52 of each first side panel 5, forming an uneven surface. In this embodiment of the present invention, the distance between the third plane P3 and the fourth plane P4 is smaller than the width of the first sub-structure A2 in the second direction D2. The width of the first cover plates 4 formed after cutting in the second direction D2 is smaller than the width of the first web plate 11 in the second direction D2.

[0028] Similarly, FIG. 4 shows the second sub-structure A3 being cut along a fourth plane P4 to form a second cover plate 6 and two second side panels 7. These two second side panels 7 have the same length, width, height, and structural outer shape. The second cover plate 6 has two opposing second surfaces 61. Each second side panel 7 has an opposing second flat surface 71 and a second cut surface 72. After the second sub-structure A3 is cut into the second cover plates 6, a protruding structure exists on the second cut surface 72 of each second side panel 7, forming an uneven surface. In this embodiment of the present invention, the distance between the third plane P3 and the fourth plane P4 is smaller than the width of the second sub-structure A3 in the second direction D2. The width of the second cover plate 6 formed after cutting in the second direction D2 is smaller than the width of the second web plate 21 in the second direction D2.

[0029] To facilitate subsequent welding of the cut plate components, in this embodiment of the present invention, the length of the first cover plate 4 in the first direction D1 is smaller than the length of the first web plate 11 in the first direction D1. The width of the first cover plate 4 in the second direction D2 is smaller than the width of the first web plate 11 in the second direction D2. In other words, the area of ​​any first surface 41 of the first cover plate 4 is smaller than the area of ​​any first mounting surface 111 of the first web plate 11. Similarly, in this embodiment of the present invention, the length of the second cover plate 6 in the first direction D1 is smaller than the length of the second web plate 21 in the first direction D1. The width of the second cover plate 6 in the second direction D2 is smaller than the width of the second web plate 21 in the second direction D2. In other words, the area of ​​any second surface 61 of the second cover plate 6 is smaller than the area of ​​any second mounting surface 211 of the second web plate 21.

[0030] In this embodiment of the present invention, the length of each first side plate 5 in the first direction D1 is smaller than the length of each first flange 12 in the first direction D1. The height of each first side plate 5 in the third direction D3 is approximately equal to the height of each first flange 12 in the third direction D3. Therefore, the area of ​​the first flat surface 51 of each first side plate 5 is smaller than the area of ​​the first exposed surface 121 of each first flange 12. Similarly, in this embodiment of the present invention, the length of each second side plate 7 in the first direction D1 is smaller than the length of each second flange 22 in the first direction D1. The height of each second side plate 7 in the third direction D3 is approximately equal to the height of each second flange 22 in the third direction D3. Therefore, the area of ​​the second flat surface 71 of each second side plate 7 is smaller than the area of ​​the second exposed surface 221 of each second flange 22.

[0031] Steps S31 and S32 can also be performed after the above-mentioned step S3. Step S31: A first partition wall 8 and a second partition wall 9 are installed on the main structure A1. The first partition wall 8 is installed between the first structural portion 1 and the third structural portion 3. The second partition wall 9 is installed between the second structural portion 2 and the third structural portion 3.

[0032] Referring to Figures 1, 3, and 6 to 7, Figure 6 is a schematic diagram of the plate-mounted steel damper of the present invention, after a first partition wall 8, a second partition wall 9, and at least one reinforcing plate 33 have been installed on one side of the main structure A1 during the manufacturing process. Figure 7 is a schematic diagram of the plate-mounted steel damper of the present invention, after a first partition wall 8, a second partition wall 9, and at least one reinforcing plate 33 have been installed on the other side of the main structure A1 during the manufacturing process. As shown in Figures 1, 3, and 6 to 7, the first partition wall 8 and the second partition wall 9 are installed on opposite sides of the main structure A1. The first partition wall 8 is located between the first structural part 1 and the third structural part 3 and is perpendicularly connected to the first web plate 11, the first flanges 12, the third flanges 32, and the third web plate 31. In other words, the first partition wall 8 is perpendicular to the first direction D1. The second partition wall 9 is located between the second structural portion 2 and the third structural portion 3 and is perpendicularly connected to the second web plate 21, the second flanges 22, the third flanges 32, and the third web plate 31. In other words, the second partition wall 9 is perpendicular to the first direction D1. As a result, the first partition wall 8 separates the first structural portion 1 from the third structural portion 3 and simultaneously serves as a reinforcing member for one side of the third structural portion 3, thereby achieving a force transmission function. The second partition wall 9 separates the second structural portion 2 from the third structural portion 3 and simultaneously serves as a reinforcing member for the other side of the third structural portion 3, thereby achieving a force transmission function.

[0033] Step S32: At least one reinforcing plate 33 is placed on the third structural part 3. Each reinforcing plate 33 is placed vertically on the third web plate 31.

[0034] As shown in FIGS. 1, 3, and 6-7, after the first and second bulkheads 8 and 9 are installed in step S31, the present invention installs at least one reinforcing plate 33 on the third structural member 3. These reinforcing plates 33 enhance the structural toughness, strength, and rigidity of the third structural member 3. Each reinforcing plate 33 is vertically installed on the third web plate 31. The number and position of the reinforcing plates 33 can be adjusted according to design requirements. For example, if only one reinforcing plate 33 is used, the reinforcing plate 33 is vertically fixed to one of the third mounting surfaces 311 of the third web plate 31. If multiple reinforcing plates 33 are installed, they can all be installed on the same third mounting surface 311 of the third web plate 31, or they can be installed on two different third mounting surfaces 311 of the third web plate 31, respectively.

[0035] In this embodiment of the present invention, the reinforcing plate 33 is connected perpendicularly to the first and second partition walls 8 and 9 or parallel to the first and second partition walls 8 and 9. For example, as shown in FIG. 6, one reinforcing plate 33 is installed on one third installation surface 311 of the third web plate 31. The reinforcing plate 33 is connected perpendicularly to the first and second partition walls 8 and 9. In other words, the reinforcing plate 33 is perpendicular to the second direction D2. As shown in FIG. 7, one reinforcing plate 33 is installed on the other third installation surface 311 of the third web plate 31. The reinforcing plate 33 is parallel to the first and second partition walls 8 and 9. In other words, the reinforcing plate 33 is perpendicular to the first direction D1. As a result, the reinforcing plate 33 acts as a web plate reinforcing member for the third web plate 31 of the third structural part 3, delaying buckling.

[0036] Step S4: The first cover plate 4 is attached to the first web plate 11, and each of the first side plates 5 is attached to the corresponding first flange 12.

[0037] Reference will now be made to Figures 1, 3, and 5 to 8. Figure 8 is a perspective view of the plate-mounted steel plate damper of the present invention. As shown in Figures 1, 3, and 5 to 8, after the above-described process, the first cover plate 4 is installed on the first web plate 11, and each first side plate 5 is installed on the corresponding first flange 12. In this embodiment of the present invention, one first surface 41 of the first cover plate 4 is installed on one first mounting surface 111 of the first web plate 11, and the first cover plate 4 serves as a structural reinforcement member for the first web plate 11. Because the area of ​​the first surface 41 of the first cover plate 4 is smaller than the area of ​​the first mounting surface 111 of the first web plate 11, when the first cover plate 4 is installed on the first web plate 11, a gap is formed between the first cover plate 4 and each of the first flanges 12 on both sides of the first web plate 11. This gap facilitates welding the first cover plate 4 to the first web plate 11. The welding method may be slot welding or plug welding, but is not limited to these methods.

[0038] In the present invention, the first flat surface 51 of each first side plate 5 is placed on the first exposed surface 121 of each first flange 12. The first side plate 5 functions as a structural reinforcement member for the first flange 12. The first flat surface 51 of the first side plate 5 can be easily welded to the first exposed surface 121 of the first flange 12. In this case, the first cut surface 52 of each first side plate 5 faces outward.

[0039] In this embodiment of the present invention, to facilitate welding and fixing each first side plate 5, each first side plate 5 has first chamfers 53 formed on both side edges along the first direction D1 near the first flat surface 51. When each first side plate 5 is installed on each first flange 12, these first chamfers 53 form a welding groove between the first flat surface 51 of each first side plate 5 and the first exposed surface 121 of the first flange 12. This welding groove is used to weld each first side plate 5 to each first flange 12 (for example, by using partial joint penetration welding (PJP)).

[0040] Step S5: The second cover plate 6 is attached to the second web plate 21. The second side plates 7 are attached to the corresponding second flanges 22.

[0041] As shown in FIGS. 1, 3, and 5 to 8, after the above steps, the present invention installs the second cover plate 6 on the second web plate 21 and installs the second side plates 7 on the second flanges 22. In this embodiment, the second surface 61 of the second cover plate 6 is installed on the second mounting surface 211 of the second web plate 21. The second cover plate 6 functions as a structural reinforcement for the second web plate 21. The area of ​​the second surface 61 of the second cover plate 6 is smaller than the area of ​​the second mounting surface 211 of the second web plate 21. Therefore, when the second cover plate 6 is installed on the second web plate 21, a gap is formed between the second cover plate 6 and the second flanges 22 on both sides of the second web plate 21. This gap is used to weld the second cover plate 6 to the second web plate 21 (for example, slot welding can be used, and plug welding can also be used). The present invention is not limited to the above welding method.

[0042] In the present invention, the second flat surface 71 of each second side plate 7 is installed on the second exposed surface 221 of each second flange 22. The second side plate 7 functions as a structural reinforcement member for the second flange 22. The second flat surface 71 of the second side plate 7 can be easily welded to the second exposed surface 221 of the second flange 22. The second cut surface 72 of each second side plate 7 faces outward.

[0043] In this embodiment of the present invention, to facilitate welding and fixing each second side plate 7, each second side plate 7 has second chamfers 73 formed on both side edges along the first direction D1 near the second flat surface 71. When each second side plate 7 is installed on each second flange 22, these second chamfers 73 form a welding groove between the second flat surface 71 of each second side plate 7 and the second exposed surface 221 of the second flange 22. This welding groove is used to weld each second side plate 7 to each second flange 22 (for example, by partial joint penetration welding (PJP)). Therefore, each second side plate 7 has second chamfers 73 formed on both side edges along the first direction D1 near the second flat surface 71.

[0044] After the plate-mounted steel plate damper 1000 of the present invention is manufactured using the aforementioned process, it comprises a first elastic part B1, a second elastic part B2, and an energy dissipation part B3. The first elastic part B1 is composed of the first structural part 1 of the main structure A1, the first cover plate 4, and each of the first side plates 5. The second elastic part B2 is composed of the second structural part 2 of the main structure A1, the second cover plate 6, and each of the second side plates 7. The energy dissipation part B3 is composed of the third structural part 3 of the main structure A1. In terms of structural design, the rigidity and strength of the first elastic part B1 and the second elastic part B2 are both greater than the rigidity and strength of the energy dissipation part B3.

[0045] The following description will be made with reference to FIGS. 8 and 9. FIG. 9 is a front view of the plate-mounted steel damper of the present invention. As shown in FIGS. 8 and 9, the plate-mounted steel damper 1000 of the present invention is installed between a first structural member E1 and a second structural member E2 of a building structure along a first direction D1. The damper reinforces the building structure and enhances shear energy dissipation. The plate-mounted steel damper 1000 of the present invention comprises a main structure A1, a first cover plate 4, a second cover plate 6, two first side panels 5, and two second side panels 7. The main structure A1 is made of H-shaped steel and has a first structural section 1, a second structural section 2, and a third structural section 3 located between the first structural section 1 and the second structural section 2. The first structural section 1 comprises a first web plate 11 and two first flanges 12. The two first flanges 12 are symmetrically and perpendicularly connected to both side edges of the first web plate 11. The second structural part 2 includes a second web plate 21 and two second flanges 22. The two second flanges 22 are symmetrically and perpendicularly connected to both side edges of the second web plate 21. The first cover plate 4 is installed on a first installation surface 111 of the first web plate 11. The first installation surface 111 is located between the first flanges 12. The second cover plate 6 is installed on a second installation surface 211 of the second web plate 21. The second installation surface 211 is located between the second flanges 22. Each first side plate 5 is installed on a first exposed surface 121 of each first flange 12 of the first structural part 1. Each second side plate 7 is installed on a second exposed surface 221 of each second flange 22 of the second structural part 2.

[0046] In this embodiment of the present invention, the main structure A1 further includes a first partition wall 8 and a second partition wall 9. The first partition wall 8 is installed between the first structural portion 1 and the third structural portion 3. The first partition wall 8 is vertically connected to the first web plate 11, each of the first flanges 12, each of the third flanges 32, and the third web plate 31. The second partition wall 9 is installed between the second structural portion 2 and the third structural portion 3. The second partition wall 9 is vertically connected to the second web plate 21, each of the second flanges 22, each of the third flanges 32, and the third web plate 31.

[0047] In an embodiment of the present invention, the third structural part 3 further includes at least one reinforcing plate 33.
