Description

この発明は、鉄骨系柱と免震装置との接合方法の技術分野に属し、更に云うと、鉄骨系柱と柱脚ベースプレートとを溶接を用いないで接合し、且つ応力伝達性能を向上させた接合方法に関する。   The present invention belongs to a technical field of a method for joining a steel system column and a seismic isolation device, and more specifically, a steel system column and a column base plate are joined without using welding, and stress transmission performance is improved. The present invention relates to a joining method.

鉄骨系柱と免震装置との接合に関して、応力伝達を確実・高効率に行うため、前記免震装置の上部プレートと鉄骨系柱の柱脚ベースプレートとを高い精度で密着させる必要がある。そのため通常は、鉄骨系柱と柱脚ベースプレートとを突き合わせて密接に溶接接合している。例えば特許文献１の「杭と構造物との接合構造及び接合方法」には、鉄骨系柱の下端へ溶接固定された方形板状の柱脚ベースプレートが、有頭の中心ボルトと、連結ボルトにより鋼管杭の上部プレートと接合された構成が開示されている。   Regarding the joining of the steel system column and the seismic isolation device, it is necessary to closely contact the upper plate of the seismic isolation device and the column base plate of the steel system column with high accuracy in order to transmit stress reliably and efficiently. For this reason, usually, the steel-based column and the column base plate are abutted and closely welded together. For example, in the “joint structure and joining method of a pile and a structure” of Patent Document 1, a square plate-like column base plate fixed to a lower end of a steel column is welded to a headed center bolt and a connecting bolt. A structure joined to an upper plate of a steel pipe pile is disclosed.

しかし、上記のように鉄骨系柱と柱脚ベースプレートとを溶接接合する方法の場合、同柱脚ベースプレートに熱歪みよる変形が生じる問題点がある。熱変形が生じた柱脚ベースプレートを免震装置等の上に載置すると、前記免震装置の上部プレートと柱脚ベースプレートとの間に隙間が発生して接触不良状態となる。すると、鉄骨系柱から免震装置等への鉛直軸力の伝達に偏心ないし偏向が生じ、免震装置が変形した状態で支持することになり免震性能に支障をきたす。のみならず、上部免震建物の建て方精度にも支障をきたすという問題点がある。   However, in the case of the method of welding and joining the steel-based column and the column base plate as described above, there is a problem that the column base plate is deformed due to thermal distortion. When the column base plate having undergone thermal deformation is placed on a base isolation device or the like, a gap is generated between the upper plate of the base isolation device and the column base base plate, resulting in a poor contact state. Then, eccentricity or deflection occurs in the transmission of the vertical axial force from the steel system column to the seismic isolation device or the like, and the seismic isolation device is supported in a deformed state, thereby impairing the seismic isolation performance. In addition, there is a problem that the accuracy of the construction of the upper seismic isolation building is also hindered.

前記溶接接合により生じる柱脚ベースプレートの変形を矯正するために、従来、柱脚ベースプレートの表面にフェーシング加工を施す等の措置が行われている。しかし、柱と溶接した柱脚ベースプレートをフェーシング加工により表面を水平に形成する作業は技術的に非常に難しく、且つ面倒なもので作業効率も悪い。更に、昨今の高層化や長大スパン化に伴い、柱脚ベースプレート形状も巨大なものとなっており、フェーシング加工はコスト及び工期に大きな影響を及ぼす。   Conventionally, in order to correct the deformation of the column base plate caused by the welding, measures such as facing processing are performed on the surface of the column base plate. However, the operation of forming the surface of the column base plate welded to the column horizontally by facing processing is technically very difficult and cumbersome and has poor work efficiency. Furthermore, with the recent increase in the number of layers and the increase in span, the shape of the column base plate has become enormous, and the facing process has a significant effect on cost and construction period.

ところで従来、鉄骨系柱と柱脚ベースプレートとを溶接接合しない技術も開示されている。例えば、特許文献２には、図５Ａ、図５Ｂに示すように、免震装置５０（積層ゴム支承）の上部プレート５１の上に載せてボルト接合した柱脚ベースプレート５２の上面に、ボルトとナットによる上向きの高さ調節部材５３を垂直上向きに立ち上がらせ、これを鉄骨系柱５４の下端の板体５５と接合して高さ調節を行い、隙間に支持片５６を差し込み、しかる後にコンクリートを打設して固める接合方法が開示されている。
特開２００４−１８３２６６号公報 特開平９−１７７３６６号公報 By the way, the technique which does not weld-join a steel-frame type | system | group column and a column base plate conventionally is also disclosed. For example, in Patent Document 2, as shown in FIGS. 5A and 5B, a bolt and a nut are mounted on the upper surface of a column base base plate 52 that is bolted and placed on an upper plate 51 of a seismic isolation device 50 (laminated rubber support). The vertical height adjustment member 53 is raised vertically upward and joined to the plate 55 at the lower end of the steel system column 54 to adjust the height, and the support piece 56 is inserted into the gap, and then the concrete is struck. A joining method that is installed and hardened is disclosed.
JP 2004-183266 A JP-A-9-177366

特許文献２の発明は、鉄骨系柱と柱脚ベースプレートとを溶接しない接合方法により、柱脚ベースプレートの熱変形を防止する技術である点が注目に値する。しかし、図５Ｂが示すように、鉄骨系柱５４からその下端部へ伝達される免震建物の荷重を、前記柱５４の下端の各所に設けられた高さ調節部材５３（ボルト）、板体５５、支持片５６が所謂点状に受けて柱脚ベースプレート５２を介して免震装置５０へ応力伝達を行う構造であり、鉄骨系柱の下端の全面で荷重を伝達する場合に比して応力伝達性能（効率）が悪く、免震装置の能力を十分に発揮できないという問題点がある。また、鉄骨系柱の下端に局部的な集中荷重が作用して部分的に塑性化する虞がある。   It is worth noting that the invention of Patent Document 2 is a technique that prevents thermal deformation of the column base plate by a joining method that does not weld the steel column and the column base plate. However, as shown in FIG. 5B, the load of the base-isolated building transmitted from the steel system column 54 to the lower end portion thereof is adjusted by height adjusting members 53 (bolts) and plate bodies provided at various locations on the lower end of the column 54. 55, the support piece 56 is received in a so-called point shape and transmits the stress to the seismic isolation device 50 via the column base plate 52, and the stress is compared to the case where the load is transmitted to the entire lower surface of the steel column. There is a problem that the transmission performance (efficiency) is poor and the capability of the seismic isolation device cannot be fully demonstrated. Moreover, there is a possibility that a localized concentrated load acts on the lower end of the steel frame column and is partially plasticized.

本発明の目的は、鉄骨系柱と柱脚ベースプレートとを溶接しない接合方法を提供することであり、柱脚ベースプレートの熱変形を排除し、且つ応力の伝達効率を向上させて、免震装置の能力を十分に発揮させる鉄骨系柱と免震装置との接合方法を提供することにある。   An object of the present invention is to provide a joining method that does not weld a steel-based column and a column base plate, eliminates thermal deformation of the column base plate, improves stress transmission efficiency, and The object is to provide a method for joining a steel-based column and a seismic isolation device to fully demonstrate its ability.

本発明の次なる目的は、管状型の鉄骨系柱の外周面及び内周面並びに管内のベースプレート上に結合材を設置し、同鉄骨系柱内へ充填材を充填して充填型鋼管柱を構成して、基礎柱と柱脚ベースプレートとの応力伝達性能を向上させる鉄骨系柱と免震装置との接合方法を提供することにある。   The next object of the present invention is to install a binding material on the outer peripheral surface and inner peripheral surface of a tubular steel column and a base plate in the pipe, and fill the steel column with a filler to form a filled steel tube column. The object is to provide a method for joining a steel-based column and a seismic isolation device that improves the stress transmission performance between the foundation column and the column base plate.
