Description

この発明は、積層ゴム支承を用いた鉄骨造（以下、Ｓ造という場合がある。）又は鉄骨鉄筋コンクリート造（以下、ＳＲＣ造という場合がある。）免震構造物の柱脚部分の建築構法の技術分野に属し、更に言えば、免震構造物の基礎構造部分の鉄骨構造体における鉄骨柱の中心と、積層ゴム支承の中心との位置合わせを容易に正確に行えるように工夫した積層ゴム支承による免震構造物の建築構法に関する。   The present invention relates to a construction method of a column base portion of a base structure of a seismic isolation structure using a steel structure using a laminated rubber bearing (hereinafter sometimes referred to as S structure) or a steel reinforced concrete structure (hereinafter also referred to as SRC structure). Laminated rubber bearings that belong to the technical field, and more specifically, have been devised so that the center of the steel column in the steel structure of the base structure part of the seismic isolation structure can be easily and accurately aligned with the center of the laminated rubber bearing. It relates to the building construction method of seismic isolation structures.

免震構造物の建築には、復元力を有する積層ゴム支承が多く使用されている。
下記の特許文献１には、積層ゴム支承とＳＲＣ造柱との接合構造が開示されている。要するに、積層ゴム支承の上側フランジ上に載せてボルト接合等したベースプレートの上面に、ボルトとナットによる上向きの高さ調節部材を垂直上向きに立ち上がらせ、これを鉄骨柱下端の板体と結合して高さおよび鉄骨柱の垂直度の調節と支持を行う。しかる後に前記ベースプレートと柱下端の板体との隙間にモルタル等のグラウト材を充填し、更に十分硬い支持片を差し込み支持させる。しかる後にコンクリートを打設してＳＲＣ柱と積層ゴム支承とを接合した柱脚部が構築されている。 In the construction of seismic isolation structures, laminated rubber bearings having a restoring force are often used.
Patent Document 1 below discloses a joint structure between a laminated rubber support and an SRC column. In short, on the upper surface of the base plate that is placed on the upper flange of the laminated rubber bearing and joined with bolts, an upward height adjustment member with bolts and nuts is raised vertically upward, and this is joined to the plate at the bottom of the steel column. Adjust and support height and steel column verticality. Thereafter, a grout material such as mortar is filled in the gap between the base plate and the plate at the lower end of the column, and a sufficiently hard support piece is inserted and supported. After that, a column base is constructed in which concrete is cast and the SRC column and the laminated rubber bearing are joined.

上記の特許文献１に記載された柱脚部接合方法の場合は、積層ゴム支承の上側フランジ上に載せてボルト接合等したベースプレートの上面に、ボルトとナットによる上向きの高さ調節部材を垂直上向きに立ち上がらせ、これを鉄骨柱下端の板体と結合して高さおよび鉄骨柱の垂直度の調節と支持を行い、しかる後に前記ベースプレートと柱下端の板体との隙間にモルタル等のグラウト材を充填し、更に十分硬い支持片を差し込み支持させ、しかる後にコンクリートを打設するなど、多くの部材を使用し多くの工数をかけて接合作業を着々と手順通りに進めるほかなく、面倒である。それでいて柱の中心と積層ゴム支承の中心とを合致させる芯出し作業に対する考慮はなされていない。
しかしながら、実際問題として、鉄骨構造体を吊り込んだ際の積層ゴム支承との芯出し作業は、予め墨出し等を行って用意しておくとは云え、物理的におよび視覚的に外部から明快に確認できる基準が存在しないかぎり、正確を期し難いことは現場作業者の常識であり、意外に手間取ることは多くの作業者が経験している問題点である。 In the case of the column base part joining method described in Patent Document 1 above, an upward height adjusting member by a bolt and a nut is placed vertically upward on the upper surface of a base plate that is mounted on the upper flange of a laminated rubber bearing and bolted. This is combined with the plate at the lower end of the steel column to adjust and support the height and the verticality of the steel column, and then grout material such as mortar in the gap between the base plate and the plate at the lower end of the column It is troublesome to use a lot of man-hours and steadily proceed the joining work according to the procedure, such as inserting and supporting a sufficiently hard support piece and then placing concrete afterwards. is there. Nevertheless, no consideration is given to the centering work for matching the center of the column with the center of the laminated rubber bearing.
However, as a practical matter, the centering work with the laminated rubber bearing when the steel structure is suspended is prepared by performing inking etc. in advance. Unless there is a standard that can be confirmed, it is common knowledge of field workers that it is difficult to be accurate, and it is a problem experienced by many workers that it takes time and effort.

従って、本発明の目的は、積層ゴム支承を用いたＳ造又はＳＲＣ造免震構造物の柱脚部分の建築における、特に鉄骨柱の中心と積層ゴム支承の中心とを一致させる位置合わせと接合作業を容易に正確に行えるように改良・工夫した、積層ゴム支承による免震構造物の建築構法を提供することである。   Accordingly, an object of the present invention is to align and join the center of the steel column and the center of the laminated rubber bearing, particularly in the construction of the column base portion of the S structure or SRC seismic isolation structure using the laminated rubber bearing. The aim is to provide a building construction method for seismic isolation structures with laminated rubber bearings that has been improved and devised so that work can be performed easily and accurately.

以下、図１〜図３に基づいて、本発明に係る積層ゴム支承による免震構造物の建築構法の実施例を説明する。
図１は、免震構造物の基礎に採用した場所打ちコンクリート杭１のフーチング上端面に積層ゴム支承２を設置し、一方、Ｓ造又はＳＲＣ造免震構造物の基礎部分を構成する鉄骨梁と鉄骨柱４（図示例は柱脚部分）とからなる鉄骨構造体３を、図示を省略したクレーン等のワイヤー５で吊り込んだ状態を示している。符号６は地面上の床付けコンクリートを指している。 Hereinafter, based on FIGS. 1-3, the Example of the building construction method of the seismic isolation structure by the laminated rubber support which concerns on this invention is described.
FIG. 1 shows a steel beam that forms a foundation part of an S-structure or SRC-type seismic isolation structure while a laminated rubber bearing 2 is installed on the footing upper end surface of a cast-in-place concrete pile 1 adopted as the foundation of the base isolation structure. And a steel structure 3 composed of steel columns 4 (column base portions in the illustrated example) are suspended by a wire 5 such as a crane (not shown) . Reference numeral 6 denotes a flooring concrete on the ground.

上記の積層ゴム支承２は、その下側フランジを場所打ちコンクリート杭１のフーチング上端面に予め用意したアンカーボルトで固定して設置されている。もっとも免震構造物の基礎は前記場所打ちコンクリート杭１に限らない。免震構造物の基礎に採用可能な公知の種々な基礎についても同様に実施することができる。積層ゴム支承２の上側フランジ２ａには、予めその上面中央部（積層ゴム支承２の中心部）に位置決め用部材としての管状部材７が垂直上向きに設置されている。一方、免震構造物の基礎部分を構成する鉄骨構造体３の下面であって鉄骨柱４の直下の柱中心位置には、位置決め用部材として前記管状部材７の中空部内へ密接に挿入可能な外径および形状の棒状部材８が、予め垂直下向きに設置されている。また、鉄骨構造体３の下面には、後述するように鉄骨構造体３の外周にコンクリートを打設し養生するまでの間、水平姿勢に仮置きするための仮置き台９も設置されている。仮置き台９は、図２に示すように予め床付けコンクリート６上に設置して用意した水平方向固定部材１０の上に仮置きされる。   The laminated rubber bearing 2 is installed with its lower flange fixed to the upper end surface of the footing of the cast-in-place concrete pile 1 with an anchor bolt prepared in advance. However, the foundation of the base isolation structure is not limited to the cast-in-place concrete pile 1. It can carry out similarly about the well-known various foundations employable as a foundation of a seismic isolation structure. On the upper flange 2a of the laminated rubber support 2, a tubular member 7 as a positioning member is installed vertically upward at the center of the upper surface (the central part of the laminated rubber support 2). On the other hand, it can be closely inserted into the hollow portion of the tubular member 7 as a positioning member at the column center position immediately below the steel column 4 on the lower surface of the steel structure 3 constituting the base part of the seismic isolation structure. A rod-shaped member 8 having an outer diameter and a shape is previously installed vertically downward. In addition, on the lower surface of the steel structure 3, a temporary placement table 9 for temporarily placing it in a horizontal posture is also provided until concrete is placed on the outer periphery of the steel structure 3 and cured as described later. . As shown in FIG. 2, the temporary placement table 9 is temporarily placed on a horizontal fixing member 10 prepared and prepared on the flooring concrete 6 in advance.

したがって、前記鉄骨構造体３の吊り込み作業は、上記の鉄骨梁と鉄骨柱４とからなる鉄骨構造体３をほぼ水平姿勢に吊って上記積層ゴム支承２の真上位置へ運び、その下面の前記棒状部材８を、積層ゴム支承２の管状部材７の中空部内へ嵌め合わせる位置合わせ作業を行う。かくして管状部材７と棒状部材８の位置が合致すると、その位置のまま鉄骨構造体３の仮置き台９を水平方向固定部材１０の上へ水平姿勢に仮置きする。 Therefore, the suspension work of the steel structure 3 is performed by suspending the steel structure 3 composed of the steel beam and the steel column 4 in a substantially horizontal posture and carrying the steel structure 3 to a position directly above the laminated rubber support 2. An alignment operation for fitting the rod-shaped member 8 into the hollow portion of the tubular member 7 of the laminated rubber support 2 is performed. Thus, when the positions of the tubular member 7 and the rod-shaped member 8 coincide with each other, the temporary placing table 9 of the steel structure 3 is temporarily placed on the horizontal fixing member 10 in the horizontal posture with the positions.

その後は、前記鉄骨構造体３の外周部分および積層ゴム支承２の上側フランジ２ａの外周にコンクリートを打設するための基礎梁底型枠１１を敷設し、ＳＲＣ造の場合には必要な鉄筋の配筋、組み立てを行う。なお、積層ゴム支承２の上側フランジ２ａの上面には予め打設コンクリートとの一体化を図るスタッド等の結合材１２を設けておいて、コンクリート１３を打設し、免震構造物のＳ造又はＳＲＣ造基礎梁部分の構築を行う。
図３で明らかなように、鉄骨構造体３の上記仮置き台９のせいは、鉄骨構造体３のコンクリート被り厚と同じ寸法とし、Ｓ造又はＳＲＣ造免震構造物の基礎梁部分および鉄骨柱４の鉛直荷重は、前記コンクリート被り部分１３を介して積層ゴム支承２へ伝達させる構成とする。この場合に、積層ゴム支承２の上記管状部材７に厚肉鋼管を採用して鉛直荷重の伝達要素に利用することも良い。 After that, a foundation beam bottom formwork 11 for placing concrete is laid on the outer periphery of the steel structure 3 and the outer periphery of the upper flange 2a of the laminated rubber support 2, and in the case of SRC construction, the necessary reinforcing bars Reinforce and assemble. In addition, a bonding material 12 such as a stud that is intended to be integrated with the placement concrete is provided in advance on the upper surface of the upper flange 2a of the laminated rubber support 2, and the concrete 13 is placed, and the S structure of the seismic isolation structure is formed. Alternatively, the SRC foundation beam part is constructed.
As is apparent in FIG. 3, because of the temporary placement table 9 of the steel structure 3, a concrete fog thickness and same size of steel structures 3, the base beam portion of the S-forming or SRC Zomen Isolated structures and The vertical load of the steel column 4 is transmitted to the laminated rubber support 2 through the concrete covering portion 13. In this case, a thick steel pipe may be adopted as the tubular member 7 of the laminated rubber support 2 and used as a vertical load transmission element.
