Description

構造物之柱脚構造及底板Pillar structure and bottom plate of structure

本發明是有關於一種構造物之柱脚構造及使用於其之底板者。The present invention relates to a pillar structure of a structure and a bottom plate used for it.

如圖7所示，一般的構造物100是由柱體101、梁105等所構成。柱體101是與基礎103接合。對如此之構造物100，在被賦予來自側方的力量X時，會在柱體101產生彎曲彎矩M。於此情況，於柱體101和基礎103的接合部，會產生最大彎曲彎矩。因此，會要求可耐受該彎曲彎矩之柱體101及基礎103的剛性。As shown in FIG. 7, a general structure 100 is composed of a column 101, a beam 105, and the like. The column 101 is joined to the foundation 103. To such a structure 100, when a force X from the side is applied, a bending moment M is generated in the column 101. In this case, the maximum bending moment will be generated at the junction of the column 101 and the foundation 103. Therefore, the rigidity of the column 101 and the foundation 103 that can withstand the bending moment is required.

作為如此柱體101下部之與基礎103的接合構造，一般是將接合於柱脚之底板對基礎以錨定螺栓進行固定的方法(例如專利文獻1)。 〔先行技術文獻〕 〔專利文獻〕As a joint structure between the lower part of the column 101 and the foundation 103, a method of fixing the bottom plate joined to the column foot to the foundation with anchor bolts is generally used (for example, Patent Document 1). [Prior Technical Document] [Patent Document]

〔專利文獻1〕日本特開2013-64244號公報 〔發明概要〕 〔發明所欲解決的課題〕[Patent Document 1] JP 2013-64244 A [Summary of the Invention] [Problems to be Solved by the Invention]

此處，在中低層構造物中，雖然鋼製的柱體101及梁105的剛性是充分的，然而混凝土製的基礎103的剛性會有不足的情況。為了獲得更堅固的基礎103，便需要更大且深的基礎103。例如，由於使用於柱體101的鋼材是規格品，所以即使選擇最便宜的柱體101，也會有對中低層構造物所要求的剛性有充分餘裕的情況。對此，基礎103和柱體101之接合部的柱脚構造需要確保可耐受彎曲彎矩之充分的剛性，而成為成本增加的要因。Here, in the middle and low-rise structure, although the rigidity of the steel column 101 and the beam 105 is sufficient, the rigidity of the concrete foundation 103 may be insufficient. In order to obtain a stronger foundation 103, a larger and deeper foundation 103 is required. For example, since the steel material used for the column 101 is a standard product, even if the cheapest column 101 is selected, there may be sufficient margin for the rigidity required for the middle and low-rise structures. In this regard, the pedestal structure of the joint between the foundation 103 and the column 101 needs to ensure sufficient rigidity to withstand the bending moment, which becomes a factor of cost increase.

對此，也有將基礎103和柱脚101之接合部作成銷構造的方法。利用作成銷構造，可使產生於柱脚之彎曲彎矩較小。因此，可作成更小的基礎103。In this regard, there is also a method of forming the joint between the foundation 103 and the pedestal 101 into a pin structure. With the pin structure, the bending moment generated in the column foot can be smaller. Therefore, a smaller foundation 103 can be made.

於此情況，對因外力所產生之彎曲彎矩，便成為藉由柱脚101及梁105的剛性來對抗。但是，如前述般，藉由銷構造，即使作用在柱體101及梁105的彎曲彎矩增加，由於習知的柱體101及梁105具有充分的剛性，所以也沒有強度上的問題。但是，銷構造需要機密的加工，便成為比一般的鋼骨柱脚價格高，結果便造成增加成本。In this case, the bending moment generated by the external force is opposed by the rigidity of the column base 101 and the beam 105. However, as described above, with the pin structure, even if the bending moment acting on the column 101 and the beam 105 is increased, since the conventional column 101 and the beam 105 have sufficient rigidity, there is no problem in strength. However, the pin structure requires confidential processing, which makes it more expensive than a general steel column foot, resulting in increased costs.

本發明是鑒於如此的問題而完成者，其目的在於提供一種便宜之構造物的柱脚構造，及用於其之底板。 〔用以解決課題的手段〕The present invention was made in view of such problems, and its object is to provide a pedestal structure of an inexpensive structure, and a bottom plate used for it. [Means to solve the problem]

為了達成前述的目的，第1本發明是一種構造物之柱腳構造，其特徵在於具備有柱體；及底板，接合於前述柱體的下端，於前述底板設置供用以將前述底板接合於基礎之錨定螺栓插通的孔，於前述底板之和前述柱體之接合部以外的部位，在前述錨定螺栓之附近形成狹縫。In order to achieve the aforementioned object, the first invention is a pedestal structure of a structure, which is characterized by having a column; and a bottom plate connected to the lower end of the column, and provided on the bottom plate for joining the bottom plate to the foundation The hole through which the anchor bolt is inserted is formed with a slit in the vicinity of the anchor bolt at a location other than the junction between the bottom plate and the column.

也可以是朝相異之複數方向形成前述狹縫，且前述錨定螺栓藉由複數方向之連續的前述狹縫從複數方向圍著。The slits may be formed in plural different directions, and the anchor bolts may be surrounded from the plural directions by the continuous slits in the plural directions.

也可以是至少朝一方向形成前述狹縫，前述錨定螺栓藉由前述狹縫、及和前述狹縫連續且和前述狹縫為相異的方向之前述底板的外側面從複數方向圍著。The slit may be formed in at least one direction, and the anchor bolt may be surrounded by the slit and the outer surface of the bottom plate continuous with the slit and in a direction different from the slit from a plurality of directions.

較佳的是於平面視，相對於接合於前述底板之前述柱體之至少其中之一的寬度，前述錨定螺栓形成於前述寬度的內側。Preferably, in plan view, the anchor bolt is formed on the inner side of the width relative to the width of at least one of the pillars joined to the bottom plate.

也可以是前述錨定螺栓從前述底板之上下以螺帽固定於前述底板。The anchor bolts may be fixed to the bottom plate with nuts from above and below the bottom plate.

較佳的是於此情況，在前述底板和前述基礎之間，至少於一部分形成間隙。Preferably, in this case, a gap is formed at least partly between the bottom plate and the foundation.

依據第1發明，利用於底板放入狹縫，底板變得易於變形，且柱腳變得易於旋轉變形。因此，可降低柱腳所產生之彎曲彎矩。又，因為在底板僅放入狹縫，所以不會如習知之銷構造般構造變得複雜，且價格便宜。According to the first invention, by inserting the slit into the bottom plate, the bottom plate becomes easy to deform, and the column foot becomes easy to rotate and deform. Therefore, the bending moment generated by the column foot can be reduced. In addition, since only a slit is inserted in the bottom plate, the structure does not become complicated like the conventional pin structure, and the price is low.

如此之底板的變形，例如利用作成為以朝相異方向連續而形成之狹縫圍著錨定螺栓，在錨定螺栓之固定部的附近，可有效率地使底板變形。Such deformation of the bottom plate can be used, for example, by making slits formed continuously in different directions to surround the anchor bolts, and the bottom plate can be effectively deformed near the fixing portion of the anchor bolts.

又，即使是作成不是以狹縫圍著錨定螺栓，而是以彼此相異方向的狹縫、及和狹縫連續之底板的外側面圍著錨定螺栓，也可有效率地使底板變形。Also, even if it is made not to surround the anchor bolts with slits, but to surround the anchor bolts with slits in different directions and the outer side of the bottom plate continuous with the slits, the bottom plate can be deformed efficiently. .

又，相對於接合在底板之柱體的至少其中之一的寬度，利用作成為使錨定螺栓形成於寬度的內側，而可使底板之旋轉變形量較大。亦即，利用使錨定螺栓之固定部靠近底板之中央附近，而可使底板有效率地旋轉變形。In addition, with respect to the width of at least one of the pillars joined to the bottom plate, the anchor bolt is formed on the inner side of the width, so that the rotational deformation of the bottom plate can be increased. That is, by making the fixing portion of the anchor bolt close to the center of the bottom plate, the bottom plate can be rotated and deformed efficiently.

又，利用將錨定螺栓從底板的上下以螺帽固定，使底板不會密接於基礎。因此，可使底板有效率地變形。In addition, the anchor bolts are fixed from the top and bottom of the bottom plate with nuts so that the bottom plate does not adhere to the foundation. Therefore, the bottom plate can be efficiently deformed.

特別是，在底板和基礎之間形成間隙時，可使底板更有效率地變形。In particular, when a gap is formed between the bottom plate and the foundation, the bottom plate can be deformed more efficiently.

第2發明是一種底板，其特徵在於具備有板狀的本體；孔，設於前述本體，供錨定螺栓插通；及狹縫，設於前述本體，形成於前述孔的附近，前述孔是藉由彼此方向相異之連續的複數方向的前述狹縫、或是前述狹縫、與朝著和前述狹縫為相異之方向連續之前述本體的外側面圍著。The second invention is a bottom plate, which is characterized by having a plate-shaped body; a hole provided in the body for insertion of anchor bolts; and a slit provided in the body and formed near the hole, the hole being The outer surface of the main body is surrounded by the slits in the continuous plural directions which are different from each other, or the slits, and the main body continuous in the direction different from the slits.

依據第2發明，由於底板變得易於變形，且柱腳變得易於旋轉變形，所以可降低柱腳所產生之彎曲灣矩。又，因為於底板僅放入狹縫，所以不會如習知的銷構造般構造變得複雜，且價格便宜。 〔發明的效果〕According to the second invention, since the bottom plate becomes easy to deform and the column foot becomes easy to rotate and deform, the bending moment generated by the column foot can be reduced. In addition, since only the slit is inserted in the bottom plate, the structure does not become complicated like the conventional pin structure, and the price is low. [Effects of the invention]

依據本發明，可提供一種價格便宜的構造物之柱腳構造及使用於其之底板。According to the present invention, it is possible to provide a pedestal structure of an inexpensive structure and a bottom plate used for it.

以下，就有關本發明之實施型態的柱脚構造1進行說明。圖1是顯示柱腳構造1的前視圖，圖2是圖1之A-A線斷面圖。柱腳構造1是由柱體3、底板5、基礎7、錨定螺栓9等所構成。Hereinafter, the pedestal structure 1 related to the embodiment of the present invention will be described. Fig. 1 is a front view showing the column foot structure 1, and Fig. 2 is a cross-sectional view taken along line A-A in Fig. 1. The column foot structure 1 is composed of a column 3, a bottom plate 5, a foundation 7, an anchor bolt 9 and the like.

柱體3例如是H鋼柱。柱體3之下端接合底板5。底板5是鋼製的板狀構件。底板5之本體5a設置孔5b，於孔5b插通錨定螺栓9。The column 3 is, for example, an H steel column. The lower end of the column 3 is joined to the bottom plate 5. The bottom plate 5 is a plate-shaped member made of steel. The body 5a of the bottom plate 5 is provided with a hole 5b, and an anchor bolt 9 is inserted through the hole 5b.

錨定螺栓9插通並固定於基礎7。又，錨定螺栓9從底板5之上下藉由螺帽15a、15b而被夾入，並固定於底板5。The anchor bolt 9 is inserted through and fixed to the foundation 7. In addition, the anchor bolt 9 is clamped from above and below the bottom plate 5 by the nuts 15 a and 15 b, and is fixed to the bottom plate 5.

此處，如圖2所示，相對於柱體3之其中一寬度(圖中D)，錨定螺栓9位於該寬度的內部(圖中C)。同樣地，相對於柱體3之另一寬度(圖中F)，錨定螺栓9位於該寬度的內部(圖中E)。亦即，相對於柱體3的寬度，錨定螺栓9不露出寬度的外側。例如，錨定螺栓9配置於底板5之中央附近。而且，在圖示的例子中，錨定螺栓9即使是相對於柱體3之任一方向的寬度雖未露出，然而只要是相對於至少其中之一的寬度，錨定螺栓9配置於柱體3之寬度的內側即可。Here, as shown in FIG. 2, relative to one of the widths of the column 3 (D in the figure), the anchor bolt 9 is located inside the width (C in the figure). Similarly, relative to the other width of the column 3 (F in the figure), the anchor bolt 9 is located inside the width (E in the figure). That is, with respect to the width of the column 3, the anchor bolt 9 does not expose the outside of the width. For example, the anchor bolt 9 is arranged near the center of the bottom plate 5. Moreover, in the example shown in the figure, even though the anchor bolt 9 is not exposed in any direction relative to the width of the column 3, as long as it is relative to at least one of the widths, the anchor bolt 9 is arranged on the column. The inside of the width of 3.

在底板5和基礎7之間，部分地設置水泥砂漿11。而且，也可以是下方之螺帽15b不一定需要，使底板5接觸於基礎7上。於此情況，水泥砂漿11便不需要。又，僅以螺帽15b便可支撐底板5及柱體3時，水泥砂漿11便不需要。Between the bottom plate 5 and the foundation 7, cement mortar 11 is partially set. Moreover, the lower nut 15b may not be necessary, so that the bottom plate 5 is in contact with the foundation 7. In this case, the cement mortar 11 is not needed. In addition, when the bottom plate 5 and the column 3 can be supported only by the nut 15b, the cement mortar 11 is not required.

水泥砂漿11是形成在比錨定螺栓9所配置的範圍稍微大的範圍。因此，水泥砂漿11僅配置在底板5之中央部附近，於底板5之外周側，在底板5和基礎7之間至少形成僅螺帽15b之厚度左右的間隙8。The cement mortar 11 is formed in a range slightly larger than the range in which the anchor bolt 9 is arranged. Therefore, the cement mortar 11 is only arranged near the center of the bottom plate 5, on the outer peripheral side of the bottom plate 5, and a gap 8 of at least the thickness of the nut 15b is formed between the bottom plate 5 and the foundation 7.

底板5設置狹縫13a、13b。狹縫13a、13b朝著彼此相異的方向形成。狹縫13a於底板5之以平面視的一側，在寬度方向的略中央形成一條且從外側面17形成為預定長度(到不搭於與柱體3的接合部的位置)的直線狀。狹縫13b是和狹縫13a略直交，且以和狹縫13a的前端交叉的方式形成一條。亦即，狹縫13a、13b相互連續，且以狹縫13a狹縫13b成略T字形。The bottom plate 5 is provided with slits 13a and 13b. The slits 13a and 13b are formed in directions different from each other. The slit 13a is formed on the side of the bottom plate 5 in plan view, and is formed in a straight line with a predetermined length from the outer side surface 17 (to the position where it does not overlap the junction with the column 3) in the approximate center of the width direction. The slit 13b is slightly orthogonal to the slit 13a, and one is formed so as to cross the tip of the slit 13a. That is, the slits 13a and 13b are continuous with each other, and the slit 13b is formed in a substantially T-shape with the slit 13a.

狹縫13a、13b是形成為圍著各個錨定螺栓9(底板5的孔)。更具體來說，藉由朝著相異的複數方向形成的狹縫13a、13b從複數方向包圍錨定螺栓9。在圖示的例子中，錨定螺栓9被從彼此連續的狹縫13a、13b及外側面17的3方向圍著。而且，以狹縫13a、13b及外側面17所圍著的一個區域配置一個錨定螺栓9。The slits 13a and 13b are formed to surround the anchor bolts 9 (holes of the bottom plate 5). More specifically, the anchor bolt 9 is surrounded from plural directions by slits 13a and 13b formed in different plural directions. In the example shown in the figure, the anchor bolt 9 is surrounded in three directions from the slits 13 a, 13 b and the outer surface 17 that are continuous with each other. In addition, one anchor bolt 9 is arranged in an area surrounded by the slits 13 a and 13 b and the outer surface 17.

如此，利用錨定螺栓9配置在朝相異方向連續之至少2方向的狹縫13a、13b或與外側面17之間，而在以錨定螺栓9固定的底板5形成變形容易部(例如圖中B)。變形容易部係於柱體3產生外力之際底板5變形，容許柱體3之旋轉變形的部位。在圖示的例子中，變形容易部形成在狹縫13b的前端、和外側面17之間(或狹縫13b和狹縫13a之前端彼此之間)。又，相對於4根錨定螺栓9，分別形成變形容易部。In this way, the anchor bolt 9 is used to arrange at least two continuous slits 13a, 13b in different directions or between the outer side surface 17, and the bottom plate 5 fixed by the anchor bolt 9 forms a deformable portion (for example, FIG. In B). The easily deformable part is a part where the bottom plate 5 deforms when an external force is generated by the column 3 and allows the rotation and deformation of the column 3. In the example shown in the figure, the easily deformable portion is formed between the front end of the slit 13b and the outer side surface 17 (or between the slit 13b and the front end of the slit 13a). In addition, the four anchor bolts 9 are respectively formed with easy deformation portions.

而且，為了形成變形容易部，也可以是錨定螺栓9藉由複數方向之連續的狹縫而被從複數方向圍著。或者，只要是錨定螺栓9至少藉由朝一方向而形成之狹縫、與該狹縫連續且與該狹縫相異的方向之底板的外側面17而被從複數方向圍著即可。如此，利用僅狹縫、或是狹縫和外側面17，藉由從至少2方向(較佳為3方向以上)圍著錨定螺栓9，而可形成變形容易部。Furthermore, in order to form the deformable portion, the anchor bolt 9 may be surrounded from plural directions by continuous slits in plural directions. Alternatively, the anchor bolt 9 may be surrounded from plural directions by at least a slit formed in one direction, and the outer surface 17 of the bottom plate continuous with the slit and in a direction different from the slit. In this way, by surrounding the anchor bolt 9 from at least two directions (preferably more than three directions) with only the slit, or the slit and the outer side surface 17, a deformable portion can be formed.

又，為使變形容易部更易於變形，如前述般，錨定螺栓9希望是儘量靠底板5的中央配置。又，希望是底板5之一部分(外周側)和基礎7之間形成間隙。利用作成如此，可使底板5之旋轉變形量較大。而且，也可以是於間隙配置海綿等彈性構件。Furthermore, in order to make the deformable portion more easily deformable, as described above, it is desirable that the anchor bolt 9 is arranged as close to the center of the bottom plate 5 as possible. Furthermore, it is desirable that a gap is formed between a part (outer peripheral side) of the bottom plate 5 and the foundation 7. By doing this, the amount of rotational deformation of the bottom plate 5 can be greater. Furthermore, an elastic member such as sponge may be arranged in the gap.

以上，依據本實施型態，當對柱體3賦予外力時，底板5會變形，而可容許柱腳的旋轉變形。因此，可使柱腳的旋轉剛性較小。因此可使基礎7較小且較淺，並可使基礎的鋼筋量減少。因此，可獲得價格便宜的柱腳構造1。As described above, according to the present embodiment, when an external force is applied to the column 3, the bottom plate 5 will be deformed, and the rotation deformation of the column foot can be allowed. Therefore, the rotation rigidity of the column foot can be made small. Therefore, the foundation 7 can be made smaller and shallower, and the amount of reinforcement of the foundation can be reduced. Therefore, an inexpensive pedestal structure 1 can be obtained.

而且，即使使柱腳構造1的剛性較小，只要是柱體3及梁的剛性有充分的餘裕時，便可確保作為構造物所必須的剛性。如前述般，若是中低層構造物時，由於柱體3等的剛性有餘裕的情況較多，所以即使是適用本發明之柱腳構造1的場合，也可就這樣使用習知的柱體3等。Furthermore, even if the rigidity of the column base structure 1 is small, as long as the rigidity of the column body 3 and the beam has sufficient margin, the rigidity necessary for the structure can be ensured. As mentioned above, in the case of a mid-to-low-rise structure, there is often a margin for the rigidity of the pillar 3, etc., so even if the pillar structure 1 of the present invention is applied, the conventional pillar 3 can be used as it is. Wait.

又，僅於底板5形成狹縫13a、13b，利用藉由狹縫13a、13b或外側面17，圍著錨定螺栓，而可形成變形容易部。因此，價格便宜，且即使與習知之銷構造等比較，可作成簡易的構造。In addition, the slits 13a and 13b are formed only in the bottom plate 5, and the anchor bolts are surrounded by the slits 13a and 13b or the outer side surface 17, thereby forming an easily deformable portion. Therefore, it is inexpensive and can be made into a simple structure even when compared with conventional pin structures.

又，利用從底板5的上下以螺帽固定錨定螺栓，而可於底板5的下方形成間隙(包含彈性構件)。因此，可易於使底板5變形。In addition, by fixing anchor bolts with nuts from the top and bottom of the bottom plate 5, a gap (including elastic members) can be formed under the bottom plate 5. Therefore, the bottom plate 5 can be easily deformed.

又，利用靠底板5之中央部配置錨定螺栓9，且作成不從柱體3之接合範圍露出，而可使底板5之旋轉變形量較大。In addition, the anchor bolt 9 is arranged close to the center of the bottom plate 5, and the anchor bolt 9 is not exposed from the joint range of the column 3, and the rotational deformation of the bottom plate 5 can be increased.

接著，就有關第2實施型態進行說明。圖3是顯示有關第2實施型態之柱腳構造1a的斷面圖。而且，於以下的說明中，有關可達成和柱腳構造1同樣機能的構成，賦予和圖1及圖2相同的符號，而省略重複說明。Next, the second embodiment will be described. Fig. 3 is a cross-sectional view showing a pedestal structure 1a related to the second embodiment. In addition, in the following description, regarding a structure that can achieve the same function as the pedestal structure 1, the same reference numerals as in FIGS. 1 and 2 are assigned, and repeated description is omitted.

柱腳構造1a雖和柱腳構造1大略相同，然而狹縫的態樣卻相異。於柱腳構造1a設置狹縫13c、13d。狹縫13c於底板5之以平面視的一側互相平行地形成3條。又，狹縫13d是和狹縫13c略直交，且以和3條狹縫13c的前端交叉的方式形成一條。亦即，狹縫13c、13d相互連續，且以狹縫13c和狹縫13d成略E字形。而且，狹縫13c、13d皆不與外側面17連續。Although the pedestal structure 1a is roughly the same as the pedestal structure 1, the shape of the slit is different. The pedestal structure 1a is provided with slits 13c and 13d. Three slits 13c are formed parallel to each other on one side of the bottom plate 5 in plan view. In addition, the slit 13d is slightly orthogonal to the slit 13c, and one slit is formed so as to cross the tips of the three slits 13c. That is, the slits 13c and 13d are continuous with each other, and the slit 13c and the slit 13d form a substantially E-shape. Moreover, neither of the slits 13c, 13d is continuous with the outer surface 17.

錨定螺栓9是以一對狹縫13c和狹縫13d從3方向圍著。因此，形成連結狹縫13c之基部彼此的變形容易部。而且，如前述般，錨定螺栓9被以至少2方向連續的狹縫圍著時，便形成變形容易部。因此，也可以是將狹縫13c僅作成中央的1條，在以連結狹縫13c、13d的前端彼此的線、和狹縫13c、13d所圍著的內部配置錨定螺栓9。The anchor bolt 9 is surrounded from three directions by a pair of slits 13c and 13d. Therefore, the easy deformation|transformation part of the base part of the connection slit 13c is formed. Furthermore, as described above, when the anchor bolt 9 is surrounded by slits that are continuous in at least two directions, a deformable portion is formed. Therefore, the slit 13c may be made only one at the center, and the anchor bolt 9 may be arranged in the interior surrounded by the line connecting the tips of the slits 13c and 13d and the slits 13c and 13d.

如此，在本實施型態中，由於以圍著錨定螺栓9的方式形成狹縫13c、13d，所以可易於使底板5變形。In this way, in this embodiment, since the slits 13c and 13d are formed to surround the anchor bolt 9, the bottom plate 5 can be easily deformed.

依據第2實施型態，可獲得和第1實施型態同樣的效果。如此，本發明也可以不使用外側面17，僅以狹縫圍著錨定螺栓9。According to the second embodiment, the same effect as the first embodiment can be obtained. In this way, the present invention may not use the outer side surface 17 and only surround the anchor bolt 9 with a slit.

接著，就第3實施型態進行說明。圖4是顯示有關第3實施型態之柱腳構造1b的前視圖，圖5是圖4之G-G線斷面圖。柱腳構造1b雖是和柱腳構造1大略相同，然而柱體3和狹縫的態樣相異。Next, the third embodiment will be described. Fig. 4 is a front view showing a pedestal structure 1b related to the third embodiment, and Fig. 5 is a cross-sectional view taken along line G-G in Fig. 4. Although the pillar structure 1b is substantially the same as the pillar structure 1, the shape of the pillar 3 and the slit are different.

柱腳構造1b之柱體3是方柱。於柱體3之下方形成切口19。如圖5所示，在對應於切口19的底板5的部位形成狹縫13e。亦即，狹縫13e形成於底板5之與柱體3之接合部以外的部位。The column body 3 of the column foot structure 1b is a square column. An incision 19 is formed under the cylinder 3. As shown in FIG. 5, a slit 13e is formed in a portion of the bottom plate 5 corresponding to the cutout 19. That is, the slit 13e is formed at a location other than the junction between the bottom plate 5 and the column 3.

於底板5之以平面視的一側，互相平行的2條狹縫13e從外側面17形成預定長度。在以狹縫13e和外側面17所圍著的區域內，配置錨定螺栓9。亦即，2處的錨定螺栓9分別被以形成於相異的方向且連續的狹縫13e和外側面17圍著。此時，連結狹縫13e的前端的部位成為變形容易部。On the side of the bottom plate 5 in a plan view, two parallel slits 13e are formed from the outer side surface 17 with a predetermined length. An anchor bolt 9 is arranged in the area surrounded by the slit 13e and the outer side surface 17. That is, the two anchor bolts 9 are respectively surrounded by continuous slits 13e and outer surfaces 17 formed in different directions. At this time, the part connecting the front end of the slit 13e becomes an easy deformation part.

而且，柱體3不只是方柱也可以作成圓柱。即使於該情況，利用設置切口19，而不會使柱體3和狹縫13e產生干擾。Moreover, the column 3 is not only a square column but also a cylinder. Even in this case, the notch 19 is provided without causing interference between the column 3 and the slit 13e.

依據第3實施型態，可獲得和第1實施型態同樣的效果。如此，本發明即使是對H鋼以外的方柱或圓柱也可適用。According to the third embodiment, the same effect as the first embodiment can be obtained. In this way, the present invention can be applied to square columns or cylinders other than H steel.

接著，就第4實施型態進行說明。圖6是柱腳構造1c的斷面圖。柱腳構造1c雖是和柱腳構造1b大略相同，然而於柱體3之內側形成狹縫13f、13g。Next, the fourth embodiment will be described. Fig. 6 is a cross-sectional view of the pedestal structure 1c. Although the pedestal structure 1c is substantially the same as the pedestal structure 1b, slits 13f and 13g are formed inside the column 3.

狹縫13f、13g相互略直交且交叉，並形成大略X字形。狹縫13f、13g不與外側面17連續，且形成於柱體3的內部。因此，在本實施型態中，在柱體3不需切口19。The slits 13f and 13g cross and cross each other slightly, and form a substantially X-shape. The slits 13f and 13g are not continuous with the outer surface 17 and are formed inside the column 3. Therefore, in this embodiment, the notch 19 is not required in the column 3.

於以狹縫13f、13g所區分的4處分別配設錨定螺栓9。亦即，錨定螺栓9是被以朝相互相異的方向連續的狹縫13f、13g所圍著。此時，連結狹縫13f、13g的前端的部位成為變形容易部。Anchor bolts 9 are respectively arranged at four places divided by slits 13f and 13g. That is, the anchor bolt 9 is surrounded by slits 13f and 13g that are continuous in different directions. At this time, the part connecting the front ends of the slits 13f and 13g becomes an easily deformable part.

依據第4實施型態，可獲得和第1實施型態同樣的效果。如此，本發明是以變形容易部和狹縫等所圍著的區域不需要為矩形，又，狹縫是不需要對外側面17為平行或垂直的方向。又，雖然省略圖示，然而狹縫不需要為直線狀，也可以是圓弧狀。即使是於該情況，1條圓弧狀狹縫是作成彼此相異方向之連續的狹縫。亦即，只要是藉由相異之複數方向連續的1條圓弧狀狹縫，從複數方向圍著錨定螺栓即可。According to the fourth embodiment, the same effect as the first embodiment can be obtained. In this way, in the present invention, the area surrounded by the easily deformable portion and the slit does not need to be rectangular, and the slit does not need to be parallel or perpendicular to the outer surface 17. In addition, although illustration is omitted, the slit does not need to be linear, and may be arc-shaped. Even in this case, one arc-shaped slit is a continuous slit made in different directions. That is, as long as it surrounds the anchor bolts from plural directions by one arc-shaped slit continuous in plural different directions.

以上，一面參照所附圖示，一面說明本發明之實施型態，然而本發明之技術範圍並不為前述之實施型態所左右。只要是熟知該項技藝者在申請專利範圍所記載之技術思想的範疇內，可想到各種變形例或修正例是很清楚的，而且就該等部分當然也可了解是屬於本發明的技術範圍。Above, while referring to the attached drawings, the embodiments of the present invention have been described.
