Description

Technical Field

[0001] This invention relates to a plate-mounted steel plate damper and its preparation method, particularly to a plate-mounted steel plate damper that is easily installed on building components and its preparation method. Prior Technology

[0002] In recent years, seismic isolation, seismic damping, and seismic resistance technologies for various buildings have been continuously developed. Generally speaking, in order to ensure the strength of the building structure to resist horizontal external forces such as earthquakes or wind, seismic damping and energy dissipation devices are usually required. The principle is mainly to use these seismic damping and energy dissipation devices to dissipate energy, so as to reduce structural deformation and avoid structural damage under strong external forces.

[0003] Steel plate damper-supported frame (SPD-MRF) is a type of metallic yielding seismic isolation frame. It utilizes additional steel plate dampers within a traditional bending frame to increase stiffness, strength, toughness, and energy dissipation capacity. Furthermore, steel plate dampers also function as shear-yield type seismic-resistant columns. Conventional steel plate dampers typically consist of an elastic section and an energy dissipation section. The elastic section generally uses ordinary steel, while the energy dissipation section uses low yield strength steel (LYP steel). However, LYP steel is expensive and difficult to install. Therefore, there is an urgent need for a seismic isolation system that is easy to manufacture, can be quickly constructed, is low-cost, and can significantly improve the seismic resistance of buildings.

For example, an element or structure containing a plurality of elements is not limited to those listed herein, but may include other elements not expressly listed but which are generally inherent to the element or structure.

[0024] Please refer to Figure 1 below, which is a flowchart of the preparation method of the plate-mounted steel plate damper of the present invention. As shown in Figure 1, the preparation method of the plate-mounted steel plate damper of the present invention includes the following steps:

[0025] Step S1: Provide H-beam steel A.

[0026] Please refer to Figures 1 and 2 together. Figure 2 is a schematic diagram of cutting H-shaped steel A along the first plane P1 and the second plane P2 perpendicular to the first direction D1 using the method of preparing the plate-type steel plate damper of the present invention. As shown in Figures 1 and 2, firstly, the present invention provides H-shaped steel A. H-shaped steel A is defined to have a length, a width, and a height, wherein the length of H-shaped steel A extends along the first direction D1, the width of H-shaped steel A extends along the second direction D2, and the height of H-shaped steel A extends along the third direction D3. Any two of the aforementioned first direction D1, second direction D2, and third direction D3 are perpendicular to each other.

[0027] Step S2: Cut H-shaped steel A along the first plane P1 and the second plane P2 perpendicular to the first direction D1, so that H-shaped steel A forms a main structure A1 and a first substructure A2 and a second substructure A3 with the same size, and the main structure A1 defines a first structural segment 1, a second structural segment 2 and a third structural segment 3 located between the first structural segment 1 and the second structural segment 2.

[0028] Please refer to Figures 1 to 3, where Figure 3 is a schematic diagram of the H-shaped steel A after cutting. As shown in Figures 1 to 3, after providing the H-shaped steel A in step S1, the present invention can then cut the H-shaped steel A along different planes perpendicular to the first direction D1. For example, in Figure 2, the H-shaped steel A is cut along the first plane P1 and the second plane P2 respectively, so that the H-shaped steel A forms 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 (i.e., the same length, width, height, and structural shape). In the present invention, the length of the main structure A1 along the first direction D1 is greater than the length of the first sub-structure A2 along the first direction D1 and the length of the second sub-structure A3 along the first direction D1. That is to say, the main structure A1 formed after cutting is a longer H-shaped steel, while the first sub-structure A2 and the second sub-structure A3 formed after cutting are relatively shorter H-shaped steel.

[0029] The main structure A1 defines a first structural segment 1, a second structural segment 2, and a third structural segment 3, with the third structural segment 3 located between the first structural segment 1 and the second structural segment 2. The first structural segment 1 includes a first web 11 and two first wing plates 12, with the two first wing plates 12 symmetrically and perpendicularly connected to the two sides of the first web 11. The first web 11 includes two opposing first mounting surfaces 111. Each first wing plate 12 includes opposing first exposed surfaces 121 and first connecting surfaces 122, with the first connecting surfaces 122 of each first wing plate 12 correspondingly connected to each side of the first web 11. The second structural segment 2 includes a second web 21 and two second wing plates 22, with the two second wing plates 22 symmetrically and perpendicularly connected to the two sides of the second web 21. The second web 21 includes two opposing second mounting surfaces 211. Each second wing plate 22 includes opposing second exposed surfaces 221 and second connecting surfaces 222. Each second wing plate 22 has a second connecting surface 222 that is correspondingly connected to each side of the second web plate 21, and each second wing plate 22 faces outward with its second exposed surface 221. The third structural segment 3 includes a third web plate 31 and two third wing plates 32, and the two third wing plates 32 are symmetrically and perpendicularly connected to the two sides of the third web plate 31. The third web plate 31 includes two opposing third mounting surfaces 311.

[0030] In one embodiment of the present invention, H-shaped steel A is cut by pre-defined first plane P1 and second plane P2, such that the length of the first substructure A2 along the first direction D1 is less than the length of the first web 11 (and the first wing 12) along the first direction D1, and the length of the second substructure A3 along the first direction D1 is less than the length of the second web 21 (and the second wing 22) along the first direction D1, so as to facilitate subsequent welding, fixing and assembly of the plates.

[0031] Step S3: Cut the first substructure A2 and the second substructure A3 along the third plane P3 and the fourth plane P4 perpendicular to the second direction D2, respectively, so that the first substructure A2 forms the first cover plate 4 and two first side plates 5 of the same size, and the second substructure A3 forms the second cover plate 6 and two second side plates 7 of the same size.

[0032] Please refer to Figures 1 to 5. Figure 4 is a schematic diagram of the preparation method of the plate-type steel plate damper of the present invention, showing the cutting of the first sub-structure A2 and the second sub-structure A3 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 being cut. As shown in Figures 1 to 5, after cutting the H-shaped steel A in the aforementioned step S2, the present invention can then cut the first sub-structure A2 and the second sub-structure A3 along different planes perpendicular to the second direction D2. For example, in Figure 4, the first sub-structure A2 is cut along the third plane P3, so that the first sub-structure A2 forms a first cover plate 4 and two first side plates 5 of the same size (i.e., having the same length, width, height and structural shape). The first cover plate 4 includes two opposing first surfaces 41. Each first side plate 5 includes opposing first flat surfaces 51 and first cut surfaces 52. After the first substructure A2 is cut to form the first cover plate 4, a portion of the protruding structure remains on the first cut surface 52 of each first side plate 5, making the first cut surface 52 a non-flat surface. In one embodiment of the present invention, the distance between the third plane P3 and the fourth plane P4 is less than the width of the first substructure A2 along the second direction D2, and the width of the first cover plate 4 formed after cutting along the second direction D2 is less than the width of the first web plate 11 along the second direction D2.

[0033] Similarly, as shown in Figure 4, the second substructure A3 is cut along the fourth plane P4, forming a second cover plate 6 and two second side plates 7 of the same size (i.e., having the same length, width, height, and structural shape). The second cover plate 6 includes two opposing second surfaces 61. Each second side plate 7 includes opposing second flat surfaces 71 and second cut surfaces 72. After the second substructure A3 is cut to form the second cover plate 6, a portion of the protruding structure remains on the second cut surfaces 72 of each second side plate 7, making the second cut surfaces 72 non-flat surfaces. In one 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 along the second direction D2, and the width of the second cover plate 6 formed after cutting along the second direction D2 is less than the width of the second web plate 21 along the second direction D2.

[0034] To facilitate subsequent welding of the cut plates, in one embodiment of the present invention, the length of the first cover plate 4 along the first direction D1 is less than the length of the first web plate 11 along the first direction D1, and the width of the first cover plate 4 along the second direction D2 is less than the width of the first web plate 11 along the second direction D2; that is, the area of ​​any first surface 41 of the first cover plate 4 is less than the area of ​​any first mounting surface 111 of the first web plate 11. Similarly, in one embodiment of the present invention, the length of the second cover plate 6 along the first direction D1 is less than the length of the second web plate 21 along the first direction D1, and the width of the second cover plate 6 along the second direction D2 is less than the width of the second web plate 21 along the second direction D2; that is, the area of ​​any second surface 61 of the second cover plate 6 is less than the area of ​​any second mounting surface 211 of the second web plate 21.

[0035] Furthermore, in one embodiment of the present invention, the length of each first side plate 5 along the first direction D1 is less than the length of each first wing plate 12 along the first direction D1, and the height of each first side plate 5 along the third direction D3 is approximately equal to the height of each first wing plate 12 along the third direction D3; that is, the area of ​​the first flat surface 51 of each first side plate 5 is less than the area of ​​the first exposed surface 121 of each first wing plate 12. Similarly, in one embodiment of the present invention, the length of each second side plate 7 along the first direction D1 is less than the length of each second wing plate 22 along the first direction D1, and the height of each second side plate 7 along the third direction D3 is approximately equal to the height of each second wing plate 22 along the third direction D3; that is, the area of ​​the second flat surface 71 of each second side plate 7 is less than the area of ​​the second exposed surface 221 of each second wing plate 22.

[0036] After the aforementioned step S3, steps S31 and S32 can be executed first. Step S31: A first partition 8 and a second partition 9 are provided on the main structure A1. The first partition 8 is located between the first structural segment 1 and the third structural segment 3, and the second partition 9 is located between the second structural segment 2 and the third structural segment 3.

[0037] Please refer to Figures 1, 3, and 6 to 7. Figure 6 is a schematic diagram showing the fabrication method of the plate-type steel plate damper of the present invention with a first partition 8, a second partition 9, and at least one stiffening plate 33 on one side of the main structure A1. Figure 7 is a schematic diagram showing the fabrication method of the plate-type steel plate damper of the present invention with a first partition 8, a second partition 9, and at least one stiffening plate 33 on the other side of the main structure A1. As shown in Figures 1, 3, and 6 to 7, the present invention can provide a first partition 8 and a second partition 9 on opposite sides of the main structure A1. The first partition 8 is located between the first structural segment 1 and the third structural segment 3, and the first partition 8 is perpendicularly connected to the first web 11, each first wing 12, each third wing 32, and the third web 31. That is, the first partition 8 is perpendicular to the first direction D1. The second partition 9 is located between the second structural segment 2 and the third structural segment 3, and the second partition 9 is perpendicularly connected to the second web 21, each of the second wing plates 22, each of the third wing plates 32, and the third web 31. That is to say, the second partition 9 is perpendicular to the first direction D1. Accordingly, the first partition 8 can not only separate the first structural segment 1 and the third structural segment 3 and serve as an end stiffener on one side of the third structural segment 3, providing a force transmission effect; while the second partition 9 can not only separate the second structural segment 2 and the third structural segment 3 and serve as an end stiffener on the other side of the third structural segment 3, providing a force transmission effect.

[0038] Step S32: At least one stiffening plate 33 is provided on the third structural segment 3, and each stiffening plate 33 is vertically provided on the third web plate 31.

[0039] As shown in Figures 1, 3, and 6 to 7, after setting the first partition 8 and the second partition 9 in step S31, the present invention can then set at least one stiffening plate 33 on the third structural segment 3 to increase the structural toughness, strength, and stiffness of the third structural segment 3. Each stiffening plate 33 is vertically set on the third web 31. The number and / or position of the at least one stiffening plate 33 can be changed according to different design requirements. For example, when the at least one stiffening plate 33 includes only a single stiffening plate 33, the stiffening plate 33 can be selectively vertically set on any one of the third setting surfaces 311 of the third web 31; when the at least one stiffening plate 33 includes a plurality of stiffening plates 33, the plurality of stiffening plates 33 can be selectively all set on the same third setting surface 311 of the third web 31, or the plurality of stiffening plates 33 can be respectively set on two third setting surfaces 311 of the third web 31.

[0040] Furthermore, in one embodiment of the present invention, at least one stiffening plate 33 is vertically connected to the first partition 8 and the second partition 9, or at least one stiffening plate 33 is parallel to the first partition 8 and the second partition 9. For example, as shown in FIG6, a single stiffening plate 33 may be provided on one of the third mounting surfaces 311 of the third web 31, and the stiffening plate 33 is vertically connected to the first partition 8 and the second partition 9. That is, the stiffening plate 33 is perpendicular to the second direction D2. As shown in FIG7, a single stiffening plate 33 may be provided on the opposite third mounting surface 311 of the third web 31, and the stiffening plate 33 is parallel to the first partition 8 and the second partition 9. That is, the stiffening plate 33 is perpendicular to the first direction D1. Accordingly, at least one stiffening plate 33 can serve as a web stiffener for the third web 31 of the third structural segment 3, providing a buckling delay effect.

[0041] Step S4: Stack the first cover plate 4 on the first web plate 11, and stack each first side plate 5 on each first wing plate 12.

[0042] Please refer to Figures 1, 3, and 5 through 8, where Figure 8 is a perspective view of the plate-type steel plate damper of the present invention. As shown in Figures 1, 3, and 5 through 8, after the aforementioned steps, the present invention can stack the first cover plate 4 on the first web plate 11, and stack each first side plate 5 on each first wing plate 12. In one embodiment of the present invention, the first cover plate 4 is stacked on any first mounting surface 111 of the first web plate 11 with any first surface 41, so that the first cover plate 4 can serve as a structural reinforcement of the first web plate 11. Since the area of ​​any one of the first surfaces 41 of the first cover plate 4 is smaller than the area of ​​any one of the first mounting surfaces 111 of the first web plate 11, when the first cover plate 4 is stacked on the first web plate 11, a gap will be formed between the first cover plate 4 and each of the first wing plates 12 located on both sides of the first web plate 11, so as to facilitate welding and fixing the first cover plate 4 relative to the first web plate 11 (for example, using slot weld, or even plug weld)). However, the present invention is not limited thereto.

[0043] In this invention, each first side plate 5 is stacked on the first exposed surface 121 of each first wing plate 12 with a first flat surface 51, so that the first side plate 5 can serve as a structural reinforcement for the corresponding first wing plate 12. Furthermore, the first flat surface 51 makes it easier to weld and fix the first side plate 5 to the first exposed surface 121 of the corresponding first wing plate 12. At this time, each first side plate 5 faces outward with its first cut surface 52 facing outward.

[0044] To facilitate the welding fixation of each first side plate 5 to each first wing plate 12, in one embodiment of the present invention, each first side plate 5 has a first chamfer 53 formed on both sides along the length of the first direction D1 and near the first flat surface 51. When each first side plate 5 is stacked on each first wing plate 12, the first chamfer 53 forms a welding groove between the first flat surface 51 of each first side plate 5 and the first exposed surface 121 of the first wing plate 12, thereby facilitating the welding fixation of each first side plate 5 relative to each first wing plate 12 (e.g., using partial joint penetration (PJP)).

[0045] Step S5: Stack the second cover plate 6 on the second web plate 21, and stack each second side plate 7 on each second wing plate 22.

[0046] As shown in Figures 1, 3, and 5 to 8, after the aforementioned steps, the present invention can stack the second cover plate 6 on the second web plate 21, and stack each second side plate 7 on each second wing plate 22. In one embodiment of the present invention, the second cover plate 6 is stacked on any second surface 61 on any second mounting surface 211 of the second web plate 21, so that the second cover plate 6 can serve as a structural reinforcement of the second web plate 21. Since the area of ​​any second surface 61 of the aforementioned second cover plate 6 is smaller than the area of ​​any second mounting surface 211 of the second web plate 21, when the second cover plate 6 is stacked on the second web plate 21, a gap will be formed between the second cover plate 6 and each second wing plate 22 located on both sides of the second web plate 21, so as to facilitate welding and fixing the second cover plate 6 relative to the second web plate 21 (for example, using slot weld, and possibly plug weld), but the present invention is not limited thereto.

[0047] In this invention, each second side plate 7 is stacked on the second exposed surface 221 of each second wing plate 22 with its second flat surface 71, so that the second side plate 7 can serve as a structural reinforcement for the corresponding second wing plate 22. Furthermore, the second side plate 7, utilizing its second flat surface 71, can be more easily welded and fixed to the second exposed surface 221 of the corresponding second wing plate 22. At this time, each second side plate 7 faces outward with its second cut surface 72 facing outward.

[0048] To facilitate the welding fixation of each second side plate 7 to each second wing plate 22, in one embodiment of the present invention, each second side plate 7 forms a second chamfer 73 on both sides along the length of the first direction D1 and near the second flat surface 71. When each second side plate 7 is stacked on each second wing plate 22, the second chamfer 73 forms a welding groove between the second flat surface 71 of each second side plate 7 and the second exposed surface 221 of the second wing plate 22, thereby facilitating the welding fixation of each second side plate 7 relative to each second wing plate 22 (e.g., using partial joint penetration, PJP). Accordingly, each second side plate 7 forms a second chamfer 73 on both sides along the length of the first direction D1 and near the second flat surface 71.

[0049] After the plate-type steel plate damper 1000 of the present invention is manufactured using the aforementioned method, the plate-type steel plate damper 1000 can be defined as a first elastic segment B1, a second elastic segment B2, and an energy dissipation segment B3. The first elastic segment B1 is composed of the first structural segment 1 of the main structure A1, the first cover plate 4, and the first side plates 5; the second elastic segment B2 is composed of the second structural segment 2 of the main structure A1, the second cover plate 6, and the second side plates 7; and the energy dissipation segment B3 is composed of the third structural segment 3 of the main structure A1. In terms of structural design, the stiffness and strength of the first elastic segment B1 and the second elastic segment B2 are both greater than those of the energy dissipation segment B3.
