Description

遲滯阻尼結構體及其組裝方法Hysteretic damping structure and assembly method thereof

本發明是關於遲滯阻尼結構體及其組裝方法。 The present invention relates to a hysteretic damping structure and an assembly method thereof.

作為本技術領域的的背景技術是例如專利文獻1記載使用由柱子及樑所構成之鋼架結構物的斜材(支撐材)的遲滯阻尼結構體。此遲滯阻尼結構體是具備配置在長方向的兩端的一對遲滯阻尼部，及連結一對遲滯阻尼部彼此的中間部所構成，其兩端部透過螺栓接頭固定於鋼架結構物。 As the background art of this technical field, for example, Patent Document 1 describes a hysteresis damping structure using oblique members (support members) of a steel frame structure composed of columns and beams. This hysteresis damping structure is composed of a pair of hysteresis damping parts disposed at both ends in the longitudinal direction, and an intermediate part connecting the pair of hysteresis damping parts. Both ends are fixed to the steel frame structure through bolt joints.

一對遲滯阻尼部分別具有組合鋼板所構成的芯材，及配設在芯材的周圍的加強鋼管。地震時遲滯阻尼結構體受到預定大小以上的交變軸向力時，使芯材變形吸收能量。又，中間部是由較芯材更高剛性的圓鋼管所構成，在交變軸向力作用時，朝一對遲滯阻尼部傳達軸向力。 The pair of hysteresis dampers each have a core material composed of combined steel plates, and a reinforced steel pipe arranged around the core material. When the hysteresis damping structure receives an alternating axial force above a predetermined magnitude during an earthquake, the core material is deformed to absorb energy. In addition, the middle part is made of a round steel pipe with higher rigidity than the core material, and when an alternating axial force acts, the axial force is transmitted to the pair of hysteretic damping parts.

但是，既有的鍋爐裝置中，例如是使用專利文獻1記載的遲滯阻尼結構體，進行鍋爐支撐鋼架的耐震補強工程的場合。但是，在鍋爐支撐鋼架的周圍，已設置有各種配管及各種電纜及機器類，限制了將遲滯阻尼結構體固定在鍋爐支撐鋼架用的空間。因此，尋求專利文獻1記載的遲滯阻尼結構體之外形的小型化。 However, in an existing boiler plant, for example, the hysteretic damping structure described in Patent Document 1 is used to perform seismic reinforcement work for a boiler supporting steel frame. However, various pipes, various cables, and equipment are installed around the boiler support steel frame, and the space for fixing the hysteresis damping structure to the boiler support steel frame is limited. Therefore, miniaturization of the external shape of the hysteresis damper structure described in Patent Document 1 is sought.

本發明是鑒於以上的實情所研創而成，其主要目的是提供一種外形可小型化的遲滯阻尼結構體。 The present invention is developed in view of the above facts, and its main purpose is to provide a hysteresis damping structure with a miniaturized shape.

為達成上述目的，代表性的本發明的遲滯阻尼結構體，係設置於朝垂直方向延伸的複數支柱子，及跨複數支的上述柱子之間朝水平方向延伸的複數支樑之間，其特徵為，具備：配置在長方向的兩端，並以芯材及加強鋼管所構成，藉塑性變形吸收能量的一對遲滯阻尼部，及連結上述一對遲滯阻尼部的中間部，上述中間部是由較上述遲滯阻尼部更高剛性，且長方向延伸的中空的矩形狀構件所構成，並具有形成於上述矩形狀構件的4個表面，上述4個表面之中相對的2個表面是與上述柱子及上述樑所形成的平面平行，其餘的相對的2個表面是與上述平面正交的構成。In order to achieve the above object, the representative hysteretic damping structure of the present invention is arranged between a plurality of pillars extending vertically, and a plurality of beams extending horizontally between the above-mentioned pillars of the plurality of branches. It is provided with: a pair of hysteretic damping parts arranged at both ends in the longitudinal direction, composed of a core material and a reinforced steel pipe, absorbing energy through plastic deformation, and a middle part connecting the pair of hysteretic damping parts, and the middle part is It is composed of a hollow rectangular member that is more rigid than the above-mentioned hysteresis damper and extends in the longitudinal direction, and has four surfaces formed on the above-mentioned rectangular member. The planes formed by the columns and the beams are parallel, and the other two opposing surfaces are perpendicular to the planes.

根據本發明，可以使遲滯阻尼結構體的外形小型化。並且，上述的以外的課題、構成及效果是可藉以下的實施形態的說明得以明確。According to the present invention, the outer shape of the hysteresis damper structure can be reduced in size. In addition, the problems, configurations, and effects other than those described above will be clarified by the description of the following embodiments.

以下，針對本發明的實施形態，參閱圖示進行說明。Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(第1實施形態) 如圖1表示，遲滯阻尼結構體100是在由垂直方向延伸的複數支柱子2，及跨複數支柱子2之間朝水平方向延伸的複數支樑3構成的鋼架結構物1中，在該等柱子2、樑3間設置於對角線上。該遲滯阻尼結構體100具備：配置在長方向的兩端的一對遲滯阻尼部11，及連結一對遲滯阻尼部11的中間部20。一對遲滯阻尼部11分別具備芯材12與加強鋼管18。遲滯阻尼結構體100是藉螺栓接頭15透過接頭部13固定在分別安裝於柱子2與樑3之間的對角接合部的接合構件4。 (first embodiment) As shown in FIG. 1 , the hysteretic damping structure 100 is in a steel frame structure 1 composed of a plurality of pillars 2 extending in the vertical direction and a plurality of girders 3 extending horizontally across the plurality of pillars 2 . The columns 2 and beams 3 are arranged on the diagonal. This hysteresis damper structure 100 includes a pair of hysteresis dampers 11 arranged at both ends in the longitudinal direction, and an intermediate portion 20 connecting the pair of hysteresis dampers 11 . The pair of hysteresis dampers 11 each includes a core material 12 and a reinforced steel pipe 18 . The hysteresis damping structure 100 is fixed to the joint members 4 installed at the diagonal joints between the columns 2 and the beams 3 through the joints 13 through the bolt joints 15 .

＜芯材12＞芯材12是組合均一厚度的鋼板形成有十字型剖面(圖2(b))。芯材12一端連接於中間部20，並且另一端連接於接頭部13。芯材12是從與中間部20的連接端包括接頭部13，朝軸向一體所形成。遲滯阻尼部11有預定的大小以上的交變軸向力作用時，藉芯材12的塑性變形吸收能量。在連接芯材12與中間部20，例如只需以使用斷續角撐板等的習知的方法進行即可。並且，在接頭部13設置藉接合構件4與螺栓接頭15接合用的螺栓孔14(圖2(a))。另外，在芯材12以提升其剛性為目的，在設有接頭部13的一側，例如藉焊接等的習知的手法固定複數個鋼製的加強板16(圖2(c))。＜Core material 12＞ The core material 12 is a cross-section formed by combining steel plates of uniform thickness ( FIG. 2( b )). The core material 12 is connected to the middle part 20 at one end and connected to the joint part 13 at the other end. The core material 12 is integrally formed in the axial direction from the connection end with the intermediate part 20 including the joint part 13 . The hysteresis damper 11 absorbs energy through the plastic deformation of the core material 12 when an alternating axial force greater than a predetermined magnitude acts. What is necessary is just to connect the core material 12 and the intermediate|middle part 20 by the well-known method using an intermittent gusset etc., for example. Furthermore, a bolt hole 14 for joining the bolt joint 15 via the joint member 4 is provided in the joint portion 13 ( FIG. 2( a )). In addition, for the purpose of increasing the rigidity of the core material 12, a plurality of steel reinforcing plates 16 are fixed on the side where the joint portion 13 is provided by a known method such as welding ( FIG. 2( c )).

＜加強鋼管18＞加強鋼管18為剖面呈矩形，透過預定的間隙d配設於芯材12的周圍。加強鋼管18內部中，使構成十字型的芯材12的突出板12a~12d的各頂部在加強鋼管18的各角部相對。加強鋼管18阻止芯材12承受交變軸向力時超過預定之間隙d的量的變形，藉以限制芯材12屈曲。藉此，芯材12即使承受壓縮軸向力時仍會顯示與承受拉伸張力時相同的彈塑性舉動。加強鋼管18設置有一端連接於中間部20，另一端為芯材12貫穿的開放端部19(圖2(a))。芯材12貫穿開放端部19，容許承受交變軸向力時的伸縮。＜Reinforced steel pipe 18＞ The reinforcing steel pipe 18 has a rectangular cross section and is disposed around the core material 12 through a predetermined gap d. Inside the reinforced steel pipe 18 , the tops of the protruding plates 12 a to 12 d constituting the cross-shaped core 12 face each other at the corners of the reinforced steel pipe 18 . The reinforced steel pipe 18 prevents the core material 12 from deforming beyond the predetermined gap d when subjected to an alternating axial force, so as to limit the core material 12 from buckling. Thus, even when the core material 12 is subjected to compressive axial force, it still exhibits the same elastic-plastic behavior as when it is subjected to tensile tension. The reinforcing steel pipe 18 is provided with one end connected to the middle portion 20 and the other end being an open end 19 through which the core material 12 penetrates ( FIG. 2( a )). The core material 12 runs through the open end 19 to allow expansion and contraction under alternating axial forces.

＜中間部20＞中間部20是位在一對遲滯阻尼部11之間，連結兩者。中間部20構成比芯材12更高剛性，在交變軸向力作用時，將軸向力傳達至一對遲滯阻尼部11。並設置中間部20，與未設置中間部20的場合遲滯阻尼結構佔據全長的結構比較，遲滯阻尼部11的製作精度管理變得容易，可以使遲滯阻尼結構體100長尺寸化。並且，降伏軸向力的調整如以遲滯阻尼部11，或軸剛向的調整如以中間部20，可個別地調整，因此針對遲滯阻尼結構體100可設定最適當的構件特性。並且，針對中間部20的詳細的形狀是如後述。＜Middle part 20＞ The middle part 20 is located between the pair of hysteresis damping parts 11 and connects them. The middle part 20 is more rigid than the core material 12, and transmits the axial force to the pair of hysteresis damping parts 11 when the alternating axial force acts. Furthermore, by providing the intermediate portion 20 , compared with the structure in which the hysteresis damping structure occupies the entire length without the intermediate portion 20 , the production precision management of the hysteresis damping portion 11 becomes easier, and the hysteresis damping structure 100 can be lengthened. Moreover, the adjustment of yielding axial force such as the hysteresis damping part 11 or the adjustment of the axial rigidity such as the middle part 20 can be individually adjusted, so that the most appropriate component characteristics can be set for the hysteresis damping structure 100 . In addition, the detailed shape of the intermediate part 20 is mentioned later.

＜遲滯阻尼結構體的基本的作用＞例如，地震負載作用時遲滯阻尼結構體100雖承受交變軸向力(拉伸力及壓縮力)，但此軸向力是透過遲滯阻尼結構體100兩端的接頭部13經過遲滯阻尼部11的芯材12傳達至中間部20。並且，拉伸軸向力到達芯材12的降伏軸向力(+Ny)時產生塑性變形(+δ)，壓縮軸向力到達芯材12的降伏軸向力(-Ny)時產生塑性變形(-δ)。此時，承受壓縮軸向力的芯材12雖欲屈曲變形，但是藉加強鋼管18限制其變形並防止屈曲。如此，遲滯阻尼結構體100的整體描繪遲滯曲線並反應，其結果，吸收地震能量使振動衰減。＜Basic function of hysteretic damping structure＞ For example, when the seismic load acts on the hysteresis damping structure 100, although it bears alternating axial force (tensile force and compression force), the axial force passes through the joints 13 at both ends of the hysteresis damping structure 100 and passes through the hysteresis damping part 11. The core material 12 is conveyed to the middle part 20 . Moreover, plastic deformation (+δ) occurs when the tensile axial force reaches the yielding axial force (+Ny) of the core material 12, and plastic deformation occurs when the compressive axial force reaches the yielding axial force (-Ny) of the core material 12. (-δ). At this time, although the core material 12 subjected to the compressive axial force intends to buckle and deform, the reinforced steel pipe 18 restricts its deformation and prevents buckling. In this way, the hysteresis damping structure 100 as a whole draws a hysteresis curve and reacts, and as a result, seismic energy is absorbed to attenuate vibration.

並且，如以上的遲滯的過程中，拉伸力在交變軸向力未作用的穩定狀態作用於芯材12時，芯材12會有通過開放端部19露出於加強鋼管18的外部的場合，但是假如露出此外部的芯材12即使承受壓縮軸向力，仍可藉著加強板16使其芯材12不產生局部性屈曲變形。In addition, in the hysteresis process described above, when the tensile force acts on the core material 12 in a steady state where the alternating axial force does not act, the core material 12 may be exposed to the outside of the reinforced steel pipe 18 through the open end portion 19. , but if the exposed core material 12 bears a compressive axial force, the core material 12 can still be prevented from local buckling deformation by means of the reinforcing plate 16 .

＜中間部20的形狀＞參閱圖1、3，針對第1實施形態相關的中間部20的詳細形狀說明。如圖1及圖3(a)、(b)表示，中間部20是由長方向(圖3(a)的左右方向，另稱為軸向)延伸的中空的矩形狀鋼管(矩形狀構件)所構成，並具有形成在該矩形狀鋼管的4個表面及與該等4個表面對應的4個內面。4個表面是由：前面20a、與此前面20a相對的後面20b、與該等前面20a及後面20b正交的上面20c、與此上面20c相對的下面20d所構成。 <Shape of middle part 20> Referring to FIGS. 1 and 3, the detailed shape of the intermediate portion 20 according to the first embodiment will be described. As shown in Figure 1 and Figure 3 (a), (b), the middle part 20 is a hollow rectangular steel pipe (rectangular member) extending in the longitudinal direction (the left-right direction of Figure 3 (a), also referred to as the axial direction). and has four surfaces formed on the rectangular steel pipe and four inner surfaces corresponding to the four surfaces. The four surfaces are composed of a front 20a, a rear 20b opposite to the front 20a, an upper 20c perpendicular to the front 20a and the rear 20b, and a lower 20d opposite to the upper 20c.

On the other hand, the upper surface 20c and the lower surface 20d (the remaining two opposing surfaces) of the intermediate portion 20 are surfaces perpendicular to the plane R thereof. In addition, in the present embodiment, the shape of the longitudinal cross-section of the intermediate portion 20 taken along a plane perpendicular to the longitudinal direction (axial direction) is "square", but it may be "rectangular". Here, "square" is not only a shape in which the four corners are completely right angles, but also includes the case where the four corners are R-shaped in terms of manufacturing. The same applies to "rectangular".

Specifically, the intermediate portion 20 has a first intermediate portion 21 and a second intermediate portion 22 . One end of the first intermediate portion 21 is connected to the hysteresis damper 11 (core material 12 ), and the other end of the first intermediate portion 21 is connected to the second intermediate portion 22 . Similarly, one end of the second intermediate portion 22 is connected to the hysteresis damper 11 (core material 12 ), and the other end of the second intermediate portion 22 is connected to the first intermediate portion 21 .

進行設置於第1拼接板23的複數個螺栓孔23a；設置於第2拼接板23的複數個螺栓孔23a；及設置於第1中間部21之複數個螺栓孔20e的對位。並且，作業員將手指、手腕、手肘等放入第1中間部21的開口窗25，將螺栓24a***各螺栓孔20e、23e，並將螺帽24b緊固於***的螺栓24a。並且，在圖4(a)的狀態，也配合假固定的螺栓24a緊固所有的螺栓24a。並且，在圖4(a)的狀態，在將螺栓24a僅***一部分的螺栓孔20e、23a的場合，在未***螺栓24a之處全部***螺栓24a，將螺帽24b緊固於***的螺栓24a。藉此，將第1拼接板23的另一端側與第2拼接板23的另一端側固定於第1中間部21(圖4(d))。針對第1中間部21的所有的表面及內面進行如以上的作業之後，最後以封板26覆蓋所有的開口窗25。藉由以上的順序，透過第1拼接板23及第2拼接板23連接第1中間部21及第2中間部22，完成遲滯阻尼結構體100的組裝作業。 A plurality of bolt holes 23a provided in the first joint plate 23; a plurality of bolt holes 23a provided in the second joint plate 23; and a plurality of bolt holes 20e provided in the first intermediate portion 21 are aligned. Then, the operator puts fingers, wrists, elbows, etc. into the opening window 25 of the first intermediate portion 21, inserts the bolts 24a into the respective bolt holes 20e, 23e, and fastens the nuts 24b to the inserted bolts 24a. And, also in the state of FIG. 4( a ), all the bolts 24 a are fastened in accordance with the temporarily fixed bolts 24 a. And, in the state of Fig. 4 (a), when the bolt 24a is only inserted into a part of the bolt holes 20e, 23a, all the bolts 24a are inserted in the place where the bolt 24a is not inserted, and the nut 24b is fastened to the inserted bolt 24a. . Thereby, the other end side of the 1st spliced plate 23 and the other end side of the 2nd spliced plate 23 are fixed to the 1st intermediate part 21 (FIG.4(d)). After the above operations are performed on all the surfaces and inner surfaces of the first intermediate portion 21 , all the opening windows 25 are finally covered with the sealing plate 26 . Through the above procedure, the first intermediate portion 21 and the second intermediate portion 22 are connected through the first splicing plate 23 and the second splicing plate 23 , and the assembly operation of the hysteresis damping structure 100 is completed.

＜效果的說明＞首先，針對中間部20的剖面形狀為正方形之外形尺寸上的效果說明。在構件產生的最大應力σ _max是以σ _max=M/Z的算式求得。在此，M為彎矩、Z為剖面係數。藉此算式，在彎矩M一定之時，為使構件產生的最大應力σ _max一定，設一定的剖面係數Z即可。由於剖面係數Z是對應構件的剖面形狀來決定，因此為使各種構件的各個剖面積與剖面係數Z相等而算出各構件的外形尺寸進行比較，可得知在相同的設計條件下(亦即，彎矩M為一定，最大應力σ _max為一定的場合)外形尺寸是成最小的剖面形狀。 <Description of Effects> First, the effects of the cross-sectional shape of the intermediate portion 20 in terms of square dimensions will be described. The maximum stress σ _max generated in the member is obtained by the formula σ _max =M/Z. Here, M is the bending moment, and Z is the section modulus. Using this formula, when the bending moment M is constant, in order to make the maximum stress σ _max produced by the member constant, it is enough to set a certain section coefficient Z. Since the section coefficient Z is determined according to the cross-sectional shape of the component, in order to make the respective cross-sectional areas of various components equal to the section coefficient Z and compare the external dimensions of each component, it can be known that under the same design conditions (that is, When the bending moment M is constant and the maximum stress σ _max is constant), the external dimension is the smallest cross-sectional shape.

圖5是在上述相同的設計條件下，比較剖面形狀為正方形、圓形、菱形的場合的外形尺寸。並且，圖5中，L1為各剖面的中立軸、L2為通過正方形的剖面上端的直線、L3為通過正方形的剖面下端的直線、L4為通過圓形的剖面上端的直線、L5為通過圓形的剖面下端的直線、L6為通過菱形的剖面上端的直線、L7為通過菱形的剖面下端的直線。Figure 5 compares the external dimensions of square, circular, and rhombus cross-sectional shapes under the same design conditions as above. In addition, in Fig. 5, L1 is the neutral axis of each cross section, L2 is a straight line passing through the upper end of the square cross section, L3 is a straight line passing through the lower end of the square cross section, L4 is a straight line passing through the upper end of the circular cross section, and L5 is a straight line passing through the circular cross section. The straight line at the lower end of the section, L6 is the straight line passing through the upper end of the rhombus section, and L7 is the straight line passing through the lower end of the rhombus section.

如圖5表示，正方形的外形尺寸h ₁是相當於上線L2與下線L3之間的長度，圓形的外形尺寸h ₂是相當於上線L4與下線L5之間的長度，菱形的外形尺寸h ₃是相當於上線L6與下線L7之間的長度。因此，正方形與圓形與菱形之間的外形尺寸的大小關係為「h ₁＜h ₂＜h ₃」。因此，剖面為正方形的場合與剖面為圓形的場合比較外形尺寸可以僅小(h ₂-h ₁)，與剖面為菱形的場合比較外形尺寸可以僅小(h ₃-h ₁)。 As shown in Figure 5, the outer dimension _h1 of the square is equivalent to the length between the upper line L2 and the lower line L3, the outer dimension _h2 of the circle is equivalent to the length between the upper line L4 and the lower line L5, and the outer dimension _h3 of the rhombus It is equivalent to the length between the upper thread L6 and the lower thread L7. Therefore, the relationship between the dimensions of the square, the circle, and the rhombus is "h ₁ <h ₂ <h ₃ ". Therefore, the external dimension of the square cross section can be reduced by (h ₂ -h ₁ ) compared with the circular cross section, and the external dimension can be reduced by (h ₃ -h ₁ ) compared with the diamond cross section.

如上述，設計使剖面積(對應每單位長度的質量)及彎矩M為一定，且作用於中間部20的最大應力σ _max為一定的場合，剖面形狀正方形的一方與其他剖面(圓形、菱形)比較可以使外形尺寸成為最小型化。並且，第1實施形態是以剖面形成為正方形的中空的矩形狀鋼管構成中間部20，因此遲滯阻尼結構體100的外形尺寸與習知比較成為小型。 As mentioned above, when the cross-sectional area (corresponding to the mass per unit length) and the bending moment M are designed to be constant, and the maximum stress σ _max acting on the middle part 20 is constant, the cross-sectional shape of the square and the other cross-sections (circle, circle, Diamond) comparison can minimize the external dimensions. Furthermore, in the first embodiment, the intermediate portion 20 is formed of a hollow rectangular steel pipe having a square cross section, so that the external dimensions of the hysteresis damper structure 100 are smaller than conventional ones.

又，在已設置的鍋爐裝置中進行耐震補強工程的場合，在鍋爐支撐鋼架的周圍，已設置有各種配管或各種電纜及機器類的舖設物，因此安裝遲滯阻尼結構體的空間有多變得非常狹窄的場合。但是，根據第1實施形態，可藉著具有中空的正方形剖面的中間部20獲得小型化，因此即使狹窄的空間，可無需進行大規模的改造工程，即可安裝遲滯阻尼結構體100。更具體而言，在安裝遲滯阻尼結構體100時，可降低與安裝於鍋爐支撐鋼架的配管、電纜、機器類等的干涉用的分解作業及改造工程的工程數。In addition, in the case of earthquake-resistant reinforcement work for the installed boiler plant, various pipes, cables, and machinery are already installed around the boiler supporting steel frame, so the space for installing the hysteretic damping structure is variable. very narrow situations. However, according to the first embodiment, since the intermediate portion 20 having a hollow square cross section can be miniaturized, the hysteresis damping structure 100 can be installed in a narrow space without large-scale remodeling. More specifically, when the hysteresis damping structure 100 is installed, the number of disassembly work and remodeling work for interference with piping, cables, equipment, etc. installed on the boiler supporting steel frame can be reduced.

又，第1實施形態中，中間部20可分割為第1中間部21與第2中間部22。因此，與一體處理中間部20的場合比較，第1中間部21及第2中間部22的處理容易。例如，與使得中間部20一體懸吊的場合比較，長度成為大約一半，因此在分別移動第1中間部21及第2中間部22時，與機器等的干涉變少而容易妥善處理，並且，懸吊負載也成為大約一半，因此可以使懸吊支架或懸吊裝置小型化。尤其在已設置的鍋爐裝置中，妥善處理用的空間及設置後的空間受到限制，因此中間部20為分割結構時具有非常高的便利性。並且，可分解中間部20進行搬運，因此維護用的地面或立足點也可小型、輕量化。In addition, in the first embodiment, the intermediate portion 20 can be divided into the first intermediate portion 21 and the second intermediate portion 22 . Therefore, the handling of the first middle part 21 and the second middle part 22 is easier than when the middle part 20 is processed integrally. For example, compared with the case where the intermediate portion 20 is suspended integrally, the length becomes about half, so when the first intermediate portion 21 and the second intermediate portion 22 are moved separately, there is less interference with machines and the like, and it is easy to properly handle, and, The suspended load is also approximately halved, so that the suspension bracket or the suspension device can be miniaturized. In particular, in an installed boiler device, the space for proper disposal and the space after installation are limited, so that the middle part 20 has a very high convenience when it has a divided structure. In addition, since the intermediate portion 20 can be disassembled and transported, the maintenance floor or foothold can also be made smaller and lighter.

又，遲滯阻尼結構體100為可分割中間部20，因此，長度、質量也可以大約一半。在如上述的遲滯阻尼結構體100安裝於已設置的鋼架結構物1時，必須將遲滯阻尼結構體100從鍋爐建物外導入鍋爐建物內，朝著預定的設置場所移動，但是在此移動途中，存在有多數的干涉物(機器、配管等)，並且，當然也未設置有通路用的地面。並且，假如即使設置通路用的地面仍會有不能滿足地面的強度的場合。In addition, since the hysteresis damping structure 100 is a divisible intermediate part 20, the length and mass may be approximately half. When the above-mentioned hysteresis damping structure 100 is installed on the installed steel frame structure 1, it is necessary to introduce the hysteresis damping structure 100 from the outside of the boiler building into the boiler building, and move toward the predetermined installation place, but during the movement , there are many interfering objects (machines, piping, etc.), and, of course, there is no ground for passage. In addition, even if the ground for access roads is installed, there may be occasions where the strength of the ground cannot be satisfied.

在由如以上狀況從鍋爐建物內的預定的設置場所移動遲滯阻尼結構體100的路徑中，會有將遲滯阻尼結構體100的負載暫時安置於已設置的鋼架結構物1的樑3的場合。此時，可考慮有以下表示的第1案例~第4案例。第1案例是藉著將掛板焊接於樑3進行安裝，透過此掛板將遲滯阻尼結構體100的負載安置於樑3的場合，此時，尤其不構成問題。In the path of moving the hysteresis damping structure 100 from the predetermined installation place in the boiler building as described above, the load of the hysteresis damping structure 100 may be temporarily placed on the beam 3 of the installed steel frame structure 1. . In this case, the first to fourth cases shown below can be considered. In the first case, the hanging plate is welded to the beam 3 for installation, and the load of the hysteresis damping structure 100 is placed on the beam 3 through the hanging plate. In this case, there is no problem in particular.

相對於此，第2案例是在懸吊移動遲滯阻尼結構體100用的負載的位置不具有樑3的場合，此時，必須重新設置設置樑3。並且，第3案例會有懸吊其負載的位置的樑3的強度不足的場合，此時，必須進行已設置之樑3的補強。並且，第4案例是在已設置的鋼架結構物1設置上述的通路用的地面，而有在此地面移動的場合，此時，也在強度不足產生時，必須進行地面的補強、底樑的補強及其他障礙項目的排除等。因此，在上述第3案例及第4案例的場合，為使得如上述的補強、追設補強產生，遲滯阻尼結構體100在長度較短的一方，或者質量(負載)較輕的一方，可減少補強範圍及補強內容。On the other hand, in the second case, there is no beam 3 at the position where the load for suspending the movement hysteresis damping structure 100 is located. In this case, the beam 3 must be newly installed. In addition, in the third case, the strength of the beam 3 at the position where the load is suspended may be insufficient, and in this case, reinforcement of the installed beam 3 is necessary. In addition, in the fourth case, the ground for the above-mentioned passage is installed on the existing steel frame structure 1, and the ground may move. At this time, when the strength is insufficient, it is necessary to reinforce the ground and the bottom beam Reinforcement and elimination of other obstacles. Therefore, in the case of the above-mentioned third example and fourth example, in order to cause the above-mentioned reinforcement and additional reinforcement to occur, the hysteresis damping structure 100 can be reduced in the shorter length or the lighter mass (load). Reinforcement scope and reinforcement content.

並且，第1實施形態中，透過跨第1中間部21與第2中間部22的連接部配置在其表面側的第1拼接板23，及配置在其內面側的第2拼接板23，連接第1中間部21及第2中間部22的構成，因此連接第1中間部21與第2連接部22的作業簡單。並且，以2個拼接板23連接第1中間部21與第2中間部22，因此作用於遲滯阻尼結構體100的負載即使大的場合，仍可承受其負載。In addition, in the first embodiment, the first splicing plate 23 arranged on the surface side of the first intermediate portion 21 and the second intermediate portion 22 across the connection portion thereof, and the second splicing plate 23 arranged on the inner surface side thereof, Since the first intermediate portion 21 and the second intermediate portion 22 are connected, the work of connecting the first intermediate portion 21 and the second connecting portion 22 is simple. Furthermore, since the first intermediate portion 21 and the second intermediate portion 22 are connected by the two splice plates 23, even if the load acting on the hysteresis damping structure 100 is large, it can still bear the load.

又，第1實施形態中，在第1中間部21及第2中間部22，分別設有開口窗25，因此在拼接板23的安裝作業時，沒有準備特殊工具等的必要，且不需要複雜的作業。又，設有封閉開口窗25的封板26，因此也具有中間部20內防止雨水或塵埃進入的優點。並且，以第1實施形態說明的組裝方法也可運用於中間部20為菱形剖面的矩形狀構件。Moreover, in the first embodiment, the opening windows 25 are respectively provided in the first intermediate portion 21 and the second intermediate portion 22, so that when the splice plate 23 is installed, it is not necessary to prepare special tools, etc., and it does not need to be complicated. homework. Moreover, since the sealing plate 26 for closing the opening window 25 is provided, there is also an advantage of preventing the entry of rainwater or dust into the middle portion 20 . Furthermore, the assembling method described in the first embodiment can also be applied to a rectangular member whose intermediate portion 20 has a rhombic cross section.

(對於其他實施形態的說明) 接著，針對中間部20之分割結構的其他的實施形態說明。並且，以下的說明中，針對與上述第1實施形態的相同構成，賦予相同符號並省略說明。 (Description of other embodiments) Next, another embodiment of the divided structure of the intermediate portion 20 will be described.

First, the hysteresis dampers 11 are respectively connected to one end sides of the first intermediate portion 21 and the second intermediate portion 22 . Next, the first flange portion 27 a of the first intermediate portion 21 is brought into contact with the second flange portion 27 b of the second intermediate portion 22 .

In particular, since the first intermediate portion 21 and the second intermediate portion 22 can be connected through the first flange portion 27a and the second flange portion 27b, the assembly operation can be simplified. Furthermore, the second embodiment is preferable when the magnitude of the load acting on the steel frame structure 1 is relatively small.

This hysteresis damping structure 300 differs from the first embodiment in that the first intermediate portion 21 and the second intermediate portion 22 are joined by welding instead of using the splice plate 23 .

針對第3實施形態相關之遲滯阻尼結構體300的組裝方法說明。首先，在第1中間部21及第2中間部22的一端側，分別連接遲滯阻尼部11。接著，將第2中間部22的另一端側與第1中間部21的另一端側對接，藉焊接接合兩者。藉此，完成此遲滯阻尼結構體300的組裝作業。The assembling method of the hysteresis damping structure 300 related to the third embodiment will be described.

This is especially effective when the magnitude of the load acting on the steel frame structure 1 is very large.

(第4實施形態) 參閱圖6(e)、(f)及圖7，針對第4實施形態相關的遲滯阻尼結構體400說明。此遲滯阻尼結構體400是在將拼接板23僅配置於第1中間部21與第2中間部22的連接部的表面側的點與第1實施形態不同。 (fourth embodiment) Referring to Fig. 6(e), (f) and Fig. 7, the hysteresis damping structure 400 according to the fourth embodiment will be described. This hysteresis damping structure 400 differs from the first embodiment in that the splice plate 23 is disposed only on the surface side of the connecting portion between the first intermediate portion 21 and the second intermediate portion 22 .

針對第4實施形態相關之遲滯阻尼結構體400的組裝方法說明。首先，在第1中間部21及第2中間部的一端側，分別連接遲滯阻尼部11。接著，在第2中間部22的另一端側的4個表面分別使用螺栓24a安裝拼接板(連結板)23的一端側。接著，以第2中間部22的另一端側與第1中間部21的另一端側抵接的狀態，在第1中間部21的另一端側的4個表面使用螺栓24a安裝拼接板23的另一端側。藉此，完成此遲滯阻尼結構體400的組裝作業。The assembling method of the hysteresis damping structure 400 related to the fourth embodiment will be described.

Next, one end side of a joining plate (joint plate) 23 is attached to each of the four surfaces on the other end side of the second intermediate portion 22 using bolts 24a. Then, with the other end side of the second intermediate portion 22 in contact with the other end side of the first intermediate portion 21, the other end of the splicing plate 23 is installed on the four surfaces on the other end side of the first intermediate portion 21 using bolts 24a. one end side. In this way, the assembly work of the hysteresis damping structure 400 is completed.

根據第4實施形態相關的遲滯阻尼結構體400，可實現與第1實施形態相同的作用效果。尤其在第4實施形態中，拼接板23的片數比第1實施形態少，因此可較第1實施形態縮短組裝作業時間。並且，第4實施形態是以運用在作用於鋼架結構物1的負載比第1實施形態小的場合為佳。又，在第4實施形態，也可設置第1實施形態表示的開口窗25。另外，也可以使用螺栓24a及螺帽24b將拼接板23安裝於中間部20的如圖7的構成。According to the hysteresis damping structure 400 according to the fourth embodiment, the same effects as those of the first embodiment can be achieved. In particular, in the fourth embodiment, the number of splice plates 23 is less than that of the first embodiment, so that the assembly work time can be shortened compared with the first embodiment.
