Abstract
Description
本発明は、地盤の沈下等に伴う建て屋基礎を修復可能とするための基礎技術に属する。 The present invention belongs to a basic technology for making it possible to repair a building foundation accompanying subsidence of the ground.
軟弱地盤上の建屋は地震等によりその基礎が傾き居住不能となる事態に陥ることがある。基礎が傾いた場合の修復方法は、基礎の下に膨張性の樹脂を注入しその膨張により基礎の傾きを修復する工法（特開２００８−２０１０８２、特開２０１０−１２６９５５）、あるいは基礎の周辺を掘り下げ、耐圧板を介し基礎をジャッキアップする方法、建て屋の基礎下を掘り起こし家屋の荷重で鋼管を支持層まで打ち込み鋼管の反力を利用して家屋を支えジャッキアップして基礎の傾きを修復する方法等が実用に供されている。 Buildings on soft ground may fall into a situation where the foundation becomes tilted due to an earthquake or the like. When the foundation is tilted, the expansive resin is injected under the foundation and the foundation is repaired by the expansion (JP 2008-201082, JP 2010-126955), or the periphery of the foundation. Method of digging down and jacking up the foundation via a pressure plate, digging up the foundation of the building and driving the steel pipe up to the support layer with the load of the house, using the reaction force of the steel pipe to support the house and jack up to repair the inclination of the foundation The method of doing is put to practical use.
本発明は、基礎が地震等で傾いた場合でも簡単に修復できる基礎の新規構造の提案にある。 The present invention resides in the proposal of a new structure of a foundation that can be easily repaired even when the foundation is tilted due to an earthquake or the like.
本発明は、建屋の基礎であって、当該基礎は上部基礎と下部基礎の２層からなり、当該２層の外縁接触面には両層に渡る空所が外面に向かって開口され、かつ前記上部基礎と下部基礎は互いにその位置が水平方向にずれないよう固定されるが、上部基礎は上方向に移動可能とした建屋の基礎である。
基礎の傾きを修復できるよう基礎を２層とし、その２層の基礎のうち上層を移動可能とした。
The present invention is a foundation of a building, the foundation is composed of two layers of an upper foundation and a lower foundation, and a void extending over both layers is opened toward the outer surface on the outer edge contact surface of the two layers, and The upper foundation and the lower foundation are fixed so that their positions do not shift in the horizontal direction, but the upper foundation is a building foundation that can move upward.
The foundation is made up of two layers so that the inclination of the foundation can be repaired, and the upper layer of the foundations of the two layers can be moved.
本発明は、（１）基礎を上下２層に構成し、２層の水平方向へのズレを防止し、上層のみを上方に移動できるようにしたため基礎を水平に修復できる。（２）２層の外縁接触面には両層に渡る空所を外面に向かって開口したため、この空所にジャッキ等を設置し上部基礎を上げることができる。 In the present invention, (1) the foundation is composed of two upper and lower layers, the horizontal displacement of the two layers is prevented, and only the upper layer can be moved upward, so that the foundation can be restored horizontally. (2) Since a space extending over both layers is opened toward the outer surface on the outer edge contact surface of the two layers, a jack or the like can be installed in this space to raise the upper foundation.
以下本発明を、図を用いて、より詳細に説明する。
図１は、２層としたべた基礎と建屋を示す概念図である。本べた基礎は、上部基礎と下部基礎の２層構造となっている。上部基礎と下部基礎の間にはシート類を挟み、両層が直接接触しないようになっている。基礎の側面縁部には両層に渡り空所が設けられ、本空所に上部基礎を上方に移動させるジャッキ等が設置できるようになっている。
Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a conceptual diagram showing a solid foundation and a building with two layers. This solid foundation has a two-layer structure consisting of an upper foundation and a lower foundation. Sheets are sandwiched between the upper foundation and the lower foundation so that the two layers do not directly contact each other. A space is provided on both sides of the side edge of the foundation, and a jack or the like for moving the upper foundation upward can be installed in this space.
図２は、べた基礎の平面図および側断面図である。本図では空所は各側面に３箇所設けられているが特にその数に制限はない。空所は上下２層の基礎にまたがるように設けられている。また上部基礎と下部基礎が地震などにより水平方向にずれないよう図では、基礎の４隅は下基礎に設けられた杭により上部基礎が嵌合している。上部基礎と嵌合する部分は細めに形成され、シリコンゴム等の弾性体が巻かれている。こうする事により、上部基礎が斜めに上昇する時の歪を弾性体が吸収する。
上部基礎と下部基礎の水平方向へのズレの防止は上記方法に限らず、例えば図３に示すように、基礎の各隅に断面L型の杭を打ち込むことで防止してもよい。
FIG. 2 is a plan view and a side sectional view of a solid foundation. In this figure, there are three vacant spaces on each side, but the number is not particularly limited. The vacant space is provided so as to straddle the upper and lower layers. In addition, in the figure, the upper foundation and the lower foundation are not horizontally displaced due to an earthquake or the like, and the upper foundation is fitted to the four corners of the foundation by piles provided on the lower foundation. A portion that fits into the upper base is formed thin, and an elastic body such as silicon rubber is wound thereon. By carrying out like this, an elastic body absorbs distortion when an upper foundation rises diagonally.
Prevention of the horizontal displacement of the upper foundation and the lower foundation is not limited to the above method, and for example, as shown in FIG. 3, it may be prevented by driving a pile having an L-shaped cross section into each corner of the foundation.
図３は、布基礎の平面図および側断面図である。基本的にはべた基礎の場合と同じである。また独立基礎の場合、各基礎を上記と同様上部基礎と下部基礎との２層構造とすればよい。 FIG. 3 is a plan view and a side sectional view of the fabric foundation. Basically, it is the same as for the solid foundation. In the case of an independent foundation, each foundation may have a two-layer structure of an upper foundation and a lower foundation as described above.
図４は、基礎側面に設けられた空所に油圧ジャッキ等を設置し、上部基礎を上方に動かす状態を示している。上部基礎を上方に移動させる方法はジャッキに限らず、空所に蓋し、蓋に設けた隙間より膨張性のポリマー溶液を流し込む方法、あるいは空所に蓋し、気密性を有する袋を挿入し、蓋に設けた隙間と袋の開口部を合わせ、空気を袋内に供給することにより膨らませることにより上部基礎を上方に移動させることでもよい。 FIG. 4 shows a state where a hydraulic jack or the like is installed in a space provided on the side surface of the foundation and the upper foundation is moved upward. The method of moving the upper foundation upward is not limited to a jack, but a method of pouring an inflatable polymer solution from a gap provided on the lid and pouring the expansive polymer solution, or inserting a bag having airtightness after covering the space. The upper base may be moved upward by inflating the gap provided in the lid with the opening of the bag and supplying air into the bag.
上部基礎を上方に移動させ水平とした後、下部基礎と上下基礎との間にコンクリート、硬質ポリウレタンフォーム等を流し込み固定すれば建屋は水平に修復される。 After the upper foundation is moved upward and leveled, concrete, rigid polyurethane foam, etc. are poured and fixed between the lower foundation and the upper and lower foundations, and the building is restored horizontally.
建屋の基礎として利用できる。特に軟弱地盤に建築する場合、地震に対する備えとして有効である。 It can be used as the foundation of a building. This is especially effective for earthquakes when building on soft ground.
