Description
【0001】
【発明の属する技術分野】
本発明は、内部が中空になっている像の耐震補強方法の技術分野に属する。
【0002】
【従来の技術】
耐震改修促進法が制定されて既存建物の耐震診断や耐震改修の検討が進められ、歴史的な建築物の保存計画も併せて進められている。歴史的な建築物の保存において、建物全体の免震化が可能ならば装飾類の保存もあまり手を加えることなく可能であるが、全ての建物を免震化することは経済的、時間的に難しいのが一般的である。耐震補強された建物で問題になりやすい、あるいは建物以上に早急に対処すべき耐震改修は、第3者障害を起こす落下物であり、例えば建物内部に飾っている彫像類が考えられる。具体的には、室内の壁面や高所に取り付けられている石膏などでできている像である。
【0003】
図3は、従来の像の耐震補強方法を示す断面図である。内部が中空になっている像1は床台2上に載置され、像1の分割部分の裏側に開口部を設け、壁3側から補強材4、5を貫通させ、像1の内部で下部の補強材5上に支柱6を立設し、支柱6と上部の補強材4を固定するとともに、支柱6に梁材7、8を水平方向に取り付け、像1を支持させるようにしている。
【0004】
【発明が解決しようとする課題】
しかしながら、上記従来の耐震補強方法においては、外見上目立たない中空像1の裏面に補強材4、5を貫通させるため、外見上見にくいとはいえ歴史的に価値のあるものを損傷することは問題があるし、また、中空像1が脆性的な材料で製作されている場合には、衝撃で壊れないという保証は十分ではなかった。また、建物の壁3側で支持させるため、建物の大がかりな改修工事が必要であり、さらに、像1の内部に大がかりな補強を行うため、実際には現場で補強することは不可能であり、また、像自体を加工する必要があることから像を取り外し別途工場で補強を行う必要があった。
【0005】
本発明は、上記問題を解決するものであって、内部が中空になっている像に損傷を与えることなく現場にて確実に補強することができる耐震補強方法を提供することを目的とする。
【0006】
【課題を解決するための手段】
上記目的を達成するために、本発明の像の耐震補強方法は、内部が中空になっている像の内部に、支持部から支柱を像の内部形状に沿って立設し、像の内部に発泡ウレタン等の充填材を充填し、像と支柱を充填材により一体化したことを特徴とする。
また、本発明の像の耐震補強方法は、内部が中空になっている像の内部に、台座から支柱を立設し、前記支柱に複数の梁材を水平方向に固定し、最下部の梁材は鉄筋で前記台座に支持し、像の内部下方に繊維補強コンクリートを充填したことを特徴とする。
以上
【0007】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照しつつ説明する。図1は、本発明の像の耐震補強方法の1実施形態を示し、図1(A)は建物内部の概観図、図1(B)は断面図である。
【0008】
図1(A)において、教会等の建物壁面3の高所の張り出し部3aには像1が設置されている。このような像1は、石膏などでできていて内部が中空となった像が多い。この像1の耐震補強を行う場合には、図1(B)に示すように、壁3の張り出し部3aに固定ベース10をボルト11により取り付け、支持部である固定ベース10から支柱12を像1の内部の形状に沿って立設し、像1の内部に発泡ウレタン等の充填材料13を充填し、像1と支柱12を充填材料13により一体化させている。これにより、大きな地震慣性力が作用しても像を壊すような応力集中を生じさせないようにすることができる。
【0009】
図2は、本発明の像の耐震補強方法の他の実施形態を示す断面図である。本実施形態は比較的大型の像に適用する例である。像1は、床2上の台座15上に載置し、支持部である床2から像1の内部に向けて多数のスタッド16aを有する鉄骨等の支柱16を立設し、支柱16に複数の梁材17を水平方向に取り付け、最下部の梁材17は鉄筋18により台座15に支持させるようにし、像1の内部下方にスチールファイバーコンクリート等の繊維補強コンクリート19を充填する。
【0010】
【発明の効果】
以上の説明から明らかなように、本発明によれば、内部が中空になっている像に損傷を与えることなく現場にて確実に補強することができる。また、建物の改修工事が不要であるとともに、万一像の分割部分が損傷を受けても像内部の支柱により脱落等の恐れがない。特に、室内の壁面や高所に取り付けられている石膏などでできている内部が中空となった像の耐震補強に有効である。

BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of a seismic reinforcement method for an image having a hollow inside.
[0002]
[Prior art]
The Act on Promotion of Earthquake-Rehabilitation Improvement has been enacted, and seismic diagnosis and retrofitting of existing buildings are underway, and historical building preservation plans are also being promoted. In the preservation of historic buildings, if the entire building can be seismically isolated, the decoration can be preserved without much modification, but it is economical and time-consuming to make all buildings seismic isolated. It is generally difficult. Seismic retrofits that are prone to problems in buildings that are seismically reinforced, or that should be dealt with more quickly than buildings, are fallen objects that cause third-party obstacles, for example, statues decorated inside the building. Specifically, it is an image made of plaster or the like attached to an indoor wall surface or high place.
[0003]
FIG. 3 is a cross-sectional view showing a conventional method for seismic reinforcement of an image. The hollow image 1 is placed on the

[Problems to be solved by the invention]
However, in the conventional seismic reinforcement method, since the reinforcing
[0005]
The present invention solves the above-described problems, and an object of the present invention is to provide a seismic reinforcement method that can surely reinforce on-site without damaging an image having a hollow inside.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, according to the method for seismic reinforcement of an image of the present invention, a support column is erected from the support portion along the internal shape of the image inside the hollow image, and the image is inside the image. It is characterized by filling with a filler such as urethane foam , and integrating the image and the column with the filler.
Also, the method of seismic reinforcement of an image of the present invention is a method in which a pillar is erected from a pedestal inside an image that is hollow inside, and a plurality of beam members are fixed in the horizontal direction on the pillar, The material is supported on the pedestal by reinforcing bars, and fiber-reinforced concrete is filled in the lower part of the inside of the image.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows one embodiment of the method for seismic reinforcement of an image of the present invention, FIG. 1 (A) is a schematic view of the inside of a building, and FIG. 1 (B) is a sectional view.

【The invention's effect】
As is apparent from the above description, according to the present invention, it is possible to reliably reinforce the image in which the inside is hollow without damaging the image. In addition, there is no need for renovation of the building, and even if the divided part of the image is damaged, there is no fear of dropping off due to the pillar inside the image. In particular, it is effective for seismic reinforcement of images in which the interior made of plaster or the like attached to an indoor wall surface or high place is hollow.
