Description

Technical Field

[0001] The present invention relates to a plate-mounted steel plate damper and a method for manufacturing the same, and in particular to a plate-mounted steel plate damper that is installed on a building component and is easy to manufacture, and a method for manufacturing the same.

Background Art

[0002] In recent years, seismic isolation, vibration control and seismic resistance technologies for various buildings have been continuously developed. Generally, in order to ensure that a building structure has sufficient strength against horizontal external forces generated by earthquakes and wind forces, it is usually necessary to install a vibration control energy dissipation device. 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 further prevent structural damage.

[0003] A moment resisting frame with steel plate dampers (SPD-MRF) is a type of metal yielding vibration control frame. This frame additionally arranges steel plate dampers on the conventional bending-resistant frame to improve the rigidity, strength, toughness and energy dissipation capacity of the system. In addition, steel plate dampers are a type of shear-yielding seismic studs. Conventional steel plate dampers include an elastic part and an energy dissipation part. Ordinary steel is used for the elastic part, and low yield strength steel (LYP steel) is used for the energy dissipation part. However, low yield strength steel has high cost and complicated construction. Therefore, there is currently a need for a vibration control system that is easy to manufacture, allows rapid construction, has low cost, and can greatly improve the seismic capacity of buildings.

For example, a component or structure including a plurality of elements is not limited to only the elements enumerated herein, and may include other elements not explicitly enumerated but inherent to the component or structure.

[0024] Figure 1 is a flow chart of the manufacturing method for the plate-mounted steel plate damper of the present invention. As shown in Figure 1, the manufacturing method for the plate-mounted steel plate damper of the present invention includes the following steps.

[0025] Step S1: providing an H-shaped steel material A.

[0026] The explanation will be given with reference to Figures 1 and 2. Figure 2 shows a schematic diagram of cutting an H-shaped steel member A along a first plane P1 and a second plane P2 perpendicular to a first direction D1, applying the manufacturing method 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 member A. The H-shaped steel member A has length, width and height. The length of the H-shaped steel member A extends along the first direction D1, the width extends along the second direction D2, and the height extends along the third direction D3. Any two of the first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other.

[0027] Step S2: The H-shaped steel member A is cut along the first plane P1 and the second plane P2, which are perpendicular to the first direction D1. The main structure A1 and the first substructure A2 and second substructure A3 of the same dimensions are formed from the H-shaped steel member A. The main structure A1 includes a first structural part 1, a second structural part 2, and a third structural part 3 located between the first structural part 1 and the second structural part 2.

[0028] The explanation will be given with reference to Figures 1 to 3. Figure 3 is a schematic diagram of the H-shaped steel member A after cutting. As shown in Figures 1 to 3, after providing the H-shaped steel member A in the aforementioned process S1, the present invention cuts the H-shaped steel member A along different planes perpendicular to the first direction D1. In Figure 2, the H-shaped steel member A is cut along the first plane P1 and the second plane P2, respectively, to form the main structure A1, the first substructure A2, and the second substructure A3. The dimensions of the first substructure A2 and the second substructure A3 are the same, and their length, width, height, and structural outline are all identical. In the present invention, the length of the main structure A1 in the first direction D1 is greater than the lengths of the first substructure A2 and the second substructure A3 in the first direction D1. After cutting, the main structure A1 is a longer H-shaped steel member, and the first substructure A2 and the second substructure A3 are shorter H-shaped steel members.

[0029] The main structure A1 includes a first structural section 1, a second structural section 2, and a third structural section 3. The third structural section 3 is 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 connected symmetrically and perpendicularly to the side edges of the first web plate 11. The first web plate 11 has two opposing first mounting surfaces 111. Each first flange 12 has an opposing first exposed surface 121 and a first connecting surface 122. The first connecting surface 122 of each first flange 12 is connected to the side edge of the first web plate 11. The second structural section 2 comprises a second web plate 21 and two second flanges 22. The two second flanges 22 are connected symmetrically and perpendicularly to the side edges of the second web plate 21. The second web plate 21 has two opposing second mounting 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 the side edge of the second web plate 21. The second exposed surface 221 of each second flange 22 faces outward. The third structure 3 comprises a third web plate 31 and two third flanges 32. The two third flanges 32 are connected symmetrically and perpendicularly to the side edges of the third web plate 31. The third web plate 31 has two opposing third mounting surfaces 311.

[0030] In this embodiment of the present invention, an H-shaped steel member A is cut along a predetermined first plane P1 and a second plane P2. After cutting, the length of the first substructure A2 in the first direction D1 is smaller than the length of the first web plate 11 and the first flange 12 in the same direction. The length of the second substructure A3 in the first direction D1 is smaller than the length of the second web plate 21 and the second flange 22 in the same direction. This dimensional relationship facilitates subsequent plate welding, fixing, and assembly work.

[0031] Step S3: The first substructure A2 and the second substructure A3 are cut along the third plane P3 and the fourth plane P4, respectively, which are perpendicular to the second direction D2. This cutting forms the first cover plate 4 and two first side plates 5 of the same dimensions from the first substructure A2. The second cover plate 6 and two second side plates 7 of the same dimensions are formed from the second substructure A3.

[0032] The explanation will be given with reference to Figures 1 to 5. Figure 4 is a schematic diagram showing the cutting of the first substructure A2 and the second substructure A3 along a third plane P3 and a fourth plane P4 perpendicular to the second direction D2 in the method for manufacturing a plate-mounted steel plate damper of the present invention. Figure 5 is a schematic diagram after the first substructure A2 and the second substructure A3 have been cut, respectively. As shown in Figures 1 to 5, after cutting the H-shaped steel material A in step S2, the present invention cuts the first substructure A2 and the second substructure A3, respectively, along different planes perpendicular to the second direction D2. For example, in Figure 4, the first substructure A2 is cut along the third plane P3, and the first cover plate 4 and two first side plates 5 of the same dimensions (i.e., having the same length, width, height and structural outline) are formed from the first substructure A2. 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 cutting the first substructure A2 to form the first cover plate 4, partial protruding structures remain on the first cut surface 52 of each first side plate 5, so the first cut surface 52 is a non-flat 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 substructure A2 in the second direction D2. The width of the first cover plate 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.

[0033] Similarly, as shown in Figure 4, the second substructure A3 is cut along the fourth plane P4 to form a second cover plate 6 and two second side plates 7 of the same dimensions (i.e., having the same length, width, height, and structural outline) from the second substructure A3. The second cover plate 6 has two opposing second surfaces 61. Each second side plate 7 has an opposing second flat surface 71 and a second cut surface 72. After cutting the second substructure A3 to form the second cover plate 6, a partial protruding structure remains on the second cut surface 72 of each second side plate 7, so the second cut surface 72 is a non-flat surface. In this embodiment of the present invention, the distance between the third plane P3 and the fourth plane P4 is less than the width of the second substructure A3 in the second direction D2. The width of the second cover plate 6 formed after cutting in the second direction D2 is less than the width of the second web plate 21 in the second direction D2.

[0034] To facilitate subsequent welding of each plate formed after cutting, in embodiments of the present invention, the length of the first cover plate 4 in a first direction D1 is smaller than the length of the first web plate 11 in a first direction D1. The width of the first cover plate 4 in a second direction D2 is smaller than the width of the first web plate 11 in a second direction D2. In other words, the area of ​​any one first surface 41 of the first cover plate 4 is smaller than the area of ​​any one first mounting surface 111 of the first web plate 11. Similarly, in embodiments of the present invention, the length of the second cover plate 6 in a first direction D1 is smaller than the length of the second web plate 21 in a first direction D1. The width of the second cover plate 6 in a second direction D2 is smaller than the width of the second web plate 21 in a second direction D2. In other words, the area of ​​any one second surface 61 of the second cover plate 6 is smaller than the area of ​​any one second mounting surface 211 of the second web plate 21.

[0035] Furthermore, in the embodiments 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. Based on the above dimensional relationship, 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 the embodiments 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. Based on the above dimensional relationship, 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.

[0036] Steps S31 and S32 can be performed after step S3 described above. Step S31: Install the first bulkhead 8 and the second bulkhead 9 on the main structure A1. The first bulkhead 8 is installed between the first structural part 1 and the third structural part 3. The second bulkhead 9 is installed between the second structural part 2 and the third structural part 3.

[0037] The invention will be explained with reference to Figures 1, 3, and 6 to 7. Figure 6 is a schematic diagram after applying the manufacturing method of the plate-mounted steel plate damper of the present invention and installing the first partition wall 8, the second partition wall 9, and at least one reinforcing plate 33 on one side of the main structure A1. Figure 7 is a schematic diagram after applying the manufacturing method of the plate-mounted steel plate damper of the present invention and installing the first partition wall 8, the second partition wall 9, and at least one reinforcing plate 33 on the other side of the main structure A1. As shown in Figures 1, 3, and 6 to 7, the present invention installs the first partition wall 8 and the second partition wall 9 on opposing 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. The first partition wall 8 is connected perpendicularly to the first web plate 11, each first flange 12, each third flange 32, and the third web plate 31. That is, the first partition wall 8 is perpendicular to the first direction D1. The second partition wall 9 is located between the second structural part 2 and the third structural part 3. The second bulkhead 9 is connected perpendicularly to the second web plate 21, each second flange 22, each third flange 32, and the third web plate 31. That is, the second bulkhead 9 is perpendicular to the first direction D1. Therefore, the first bulkhead 8 separates the first structural part 1 and the third structural part 3, and at the same time, it provides a force transmission function as a reinforcing member at one end of the third structural part 3. The second bulkhead 9 separates the second structural part 2 and the third structural part 3, and at the same time, it provides a force transmission function as a reinforcing member at the other end of the third structural part 3.

[0038] Step S32: At least one reinforcing plate 33 is installed on the third structural part 3. Each reinforcing plate 33 is installed perpendicular to the third web plate 31.

[0039] The invention will be explained with reference to Figures 1, 3, and 6 to 7. After the installation of the first partition wall 8 and the second partition wall 9 is completed in step S31, the present invention installs at least one reinforcing plate 33 on the third structural part 3. This reinforcing plate 33 increases the structural toughness, strength, and rigidity of the third structural part 3. Each reinforcing plate 33 is installed perpendicular to the third web plate 31. The number and installation positions of the reinforcing plates 33 can be adjusted according to different design requirements. For example, if only one reinforcing plate 33 is installed, it can be installed perpendicular to any one of the third installation surfaces 311 of the third web plate 31. If multiple reinforcing plates 33 are installed, all of these reinforcing plates 33 can be installed on the same third installation surface 311 of the third web plate 31, or they can be installed on two different third installation surfaces 311 of the third web plate 31.

[0040] Furthermore, in embodiments of the present invention, at least one reinforcing plate 33 is connected perpendicularly to the first partition wall 8 and the second partition wall 9, or at least one reinforcing plate 33 is installed parallel to the first partition wall 8 and the second partition wall 9. For example, as shown in Figure 6, one reinforcing plate 33 is installed on one third installation surface 311 of the third web plate 31. This reinforcing plate 33 is connected perpendicularly to the first partition wall 8 and the second partition wall 9. That is, the reinforcing plate 33 is perpendicular to the second direction D2. As shown in Figure 7, one reinforcing plate 33 is installed on the other third installation surface 311 of the third web plate 31. This reinforcing plate 33 is installed parallel to the first partition wall 8 and the second partition wall 9. That is, the reinforcing plate 33 is perpendicular to the first direction D1. Thus, the reinforcing plate 33 functions as a reinforcing structure of the third web plate 31, effectively delaying the buckling phenomenon of the third structural part 3.

[0041] Step S4: The first cover plate 4 is installed on the first web plate 11, and each first side plate 5 is installed on each first flange 12.

[0042] The invention will be described with reference 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 steps, the present invention installs the first cover plate 4 on the first web plate 11 and each first side plate 5 on the first flange 12. In the embodiment of the present invention, one first surface 41 of the first cover plate 4 is installed on one first installation surface 111 of the first web plate 11. The first cover plate 4 functions as a structural reinforcing member of the first web plate 11. The area of ​​the first surface 41 of the first cover plate 4 is smaller than the area of ​​the first installation surface 111 of the first web plate 11. Therefore, 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 first flange 12 located on both sides of the first web plate 11. This gap facilitates the welding joint of the first cover plate 4 and the first web plate 11. The welding method is, but is not limited to, slot welding or plug welding.

[0043] In this invention, the first flat surface 51 of each first side plate 5 is placed on the first exposed surface 121 of the first flange 12. The first side plate 5 functions as a structural reinforcing member of the first flange 12. Furthermore, the first flat surface 51 of the first side plate 5 can be easily welded and fixed to the first exposed surface 121 of the first flange 12. After installation, the first cut surface 52 of each first side plate 5 faces outward.

[0044] In this embodiment of the present invention, first chamfers 53 are formed on both side edges of each first side plate 5 along the first direction D1 and near the first flat surface 51, in order to weld and fix each first side plate 5 to the first flange 12. When each first side plate 5 is installed on the first flange 12, these first chamfers 53 form a welding groove between the first flat surface 51 of the first side plate 5 and the first exposed surface 121 of the first flange 12. This welding groove is used to weld and fix the first side plate 5 and the first flange 12. The welding method includes partial joint penetration (PJP) technique.

[0045] Step S5: The second cover plate 6 is installed on the second web plate 21, and each second side plate 7 is installed on each second flange 22.

[0046] As shown in Figures 1, 3 and 5 to 8, after the above-described steps, the second cover plate 6 is installed on the second web plate 21 and each second side plate 7 is installed on the second flange 22. In this embodiment of the present invention, one second surface 61 of the second cover plate 6 is installed on one second mounting surface 211 of the second web plate 21. The second cover plate 6 functions as a structural reinforcing member of 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 each second flange 22 located on both sides of the second web plate 21. This gap facilitates the welding joint of the second cover plate 6 and the second web plate 21. The welding method is, but is not limited to, slot welding or plug welding.

[0047] In this invention, the second flat surface 71 of each second side plate 7 is placed on the second exposed surface 221 of each second flange 22. The second side plate 7 functions as a structural reinforcing member of the second flange 22. The second flat surface 71 of the second side plate 7 and the second exposed surface 221 of the second flange 22 are in contact and can be easily welded and fixed. The second cut surface 72 of each second side plate 7 faces outward.

[0048] In embodiments of the present invention, second chamfers 73 are formed on both side edges of each second side plate 7 along the first direction D1 and near the second flat surface 71. This design is convenient for welding the second side plate 7 to the second flange 22. When the second side plate 7 is installed on the second flange 22, the second chamfers 73 form a welding groove between the second flat surface 71 of the second side plate 7 and the second exposed surface 221 of the second flange 22. This welding groove is used for welding and fixing the second side plate 7 and the second flange 22 (for example, by employing partial joint penetration (PJP)).

[0049] The plate-mounted steel plate damper 1000 of the present invention, after being manufactured by the method described above, has a first elastic section B1, a second elastic section B2, and an energy dissipation section B3. The first elastic section B1 is composed of a first structural section 1, a first cover plate 4, and their first side plates 5 of the main structure A1. The second elastic section B2 is composed of a second structural section 2, a second cover plate 6, and their second side plates 7 of the main structure A1. The energy dissipation section B3 is composed of a third structural section 3 of the main structure A1. In the structural design, the rigidity and strength of both the first elastic section B1 and the second elastic section B2 are greater than the rigidity and strength of the energy dissipation section B3.

[0050] The invention will be described with reference to Figures 8 and 9. Figure 9 is a front view of the plate-mounted steel plate damper of the present invention. As shown in Figures 8 and 9, the present invention provides a plate-mounted steel plate damper 1000 manufactured using the manufacturing method described above. The plate-mounted steel plate damper 1000 of the present invention is installed between a first component E1 and a second component E2 of a building body along a first direction D1, reinforcing the building body and enhancing the shear energy dissipation effect. The plate-mounted steel plate damper 1000 of the present invention includes a main structure A1, a first cover plate 4, a second cover plate 6, two first side plates 5, and two second side plates 7. The main structure A1 is made of H-shaped steel and includes a first structural part 1, a second structural part 2, and a third structural part 3 located between the first structural part 1 and the second structural part 2. The first structural part 1 has a first web plate 11 and two first flanges 12. The two first flanges 12 are connected symmetrically and perpendicularly to both side edges of the first web plate 11. The second structural part 2 has a second web plate 21 and two second flanges 22. The two second flanges 22 are connected symmetrically and perpendicularly to both side edges of the second web plate 21. The first cover plate 4 is installed on one first mounting surface 111 of the first web plate 11. This first mounting surface 111 is located between the two first flanges 12. The second cover plate 6 is installed on one second mounting surface 211 of the second web plate 21. This second mounting surface 211 is located between the two second flanges 22. Each first side plate 5 is installed on the first exposed surface 121 of the first flange 12 of the first structural part 1.

[0053] In embodiments 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. Therefore, 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. A gap is also formed between the first cover plate 4 and the first partition wall 8. The aforementioned gaps are convenient for welding the first cover plate 4 and the first web plate 11 together. 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. 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 each of the second flanges 22 on both sides of the second web plate 21. A gap is also formed between the second cover plate 6 and the second partition wall 9. This gap is convenient for welding and fixing the second cover plate 6 and the second web plate 21.

[0054] In the embodiment of the present invention, the width of the first elastic portion B1 in the second direction D2 is basically equal to the width of the second elastic portion B2 in the second direction D2. The widths of both the first elastic portion B1 and the second elastic portion B2 in the second direction D2 are greater than the width of the energy dissipation portion B3 in the second direction D2. Also, the cross-sectional area of ​​the first elastic portion B1 perpendicular to the first direction D1 is basically equal to the cross-sectional area of ​​the second elastic portion B2 perpendicular to the first direction D1. The cross-sectional areas of both the first elastic portion B1 and the second elastic portion B2 perpendicular to the first direction D1 are greater than the cross-sectional area of ​​the energy dissipation portion B3 perpendicular to the first direction D1.

[0055] In summary, the plate-mounted steel damper of the present invention is manufactured using a single H-shaped steel beam. After cutting the H-shaped steel beam, all the necessary structural components of the plate-mounted steel damper are formed. By assembling and welding all the necessary structural components together, the manufacturing of the plate-mounted steel damper of the present invention is completed. Therefore, the plate-mounted steel damper of the present invention reduces manufacturing costs and assembly complexity, while simultaneously providing better structural toughness, strength, and rigidity, achieving the effects of shear energy dissipation and torsional deformation prevention.
