Description

本発明は、ユニット建物を構成する建物ユニットの基礎への固定構造に係り、特に、建物ユニットを基礎へ強固に固定できる固定構造と、この固定構造を用いてフレーム耐力を強化したユニット建物に関する。   The present invention relates to a structure for fixing a building unit constituting a unit building to a foundation, and more particularly, to a fixing structure capable of firmly fixing a building unit to a foundation and a unit building whose frame strength is enhanced by using this fixing structure.

従来、この種の建物ユニットの固定構造としては、下部を基礎に埋設させ且つ上部を基礎の上端面から突出させたアンカーボルトが設けられ、基礎の上端面上に載置された建物ユニットの床梁のボルト挿通孔にアンカーボルトの上部が挿通され、ボルト挿通孔の内面とアンカーボルトとの間の間隙にグラウト剤が充填されていると共に、アンカーボルトの上部の床梁から突出する部分にナットを螺着して締付けることにより、床梁を基礎上に接合固定している（例えば、特許文献１参照）。   Conventionally, as a fixing structure of this type of building unit, a floor of a building unit that has been mounted on the upper end surface of the foundation has been provided with anchor bolts that are embedded in the foundation and projecting from the upper end surface of the foundation.

ところで、前記構造の建物ユニット３１は、図９に示されるように、基礎３２上に載置され、柱材３３と下梁３４とは補強プレート３５を介して溶接され、この溶接部を貫通するアンカーボルト３６にナット３７を螺合させて基礎３２に固定されている。このように建物ユニット３１は、基礎３２から立ち上げたアンカーボルト３６に固定される際、建物ユニットを構成する四隅の柱材３３の下端部をアンカー固定せず、柱材より距離Ｌだけずらした位置でアンカー固定している。すなわち、立ち上げたアンカーボルト３６と柱材３３とを結合することができないため、柱材の中心から距離Ｌだけ離れた位置でアンカー固定している。このため、地震力や強風等の風圧力により建物ユニットに水平方向の外力Ｆ１が加わると、柱材の中心とアンカーボルトの中心とがずれているため、柱材を浮き上がらせる力Ｆ２が加わり、建物ユニットのフレーム耐力が低下する恐れがあった。   By the way, as shown in FIG. 9, the building unit 31 having the above structure is placed on the foundation 32, and the column member 33 and the lower beam 34 are welded via the reinforcing plate 35 and penetrate through the welded portion. A nut 37 is screwed onto the anchor bolt 36 and is fixed to the foundation 32. As described above, when the building unit 31 is fixed to the anchor bolt 36 raised from the foundation 32, the lower end portion of the pillar material 33 at the four corners constituting the building unit is not anchored and is shifted by a distance L from the pillar material. Anchored in position. That is, since the raised anchor bolt 36 and the column member 33 cannot be coupled, the anchor is fixed at a position separated by a distance L from the center of the column member. For this reason, when a horizontal external force F1 is applied to the building unit due to wind pressure such as seismic force or strong wind, the center of the column and the center of the anchor bolt are misaligned, so a force F2 to lift the column is added, The frame strength of the building unit could be reduced.

At the four corners are constituted by square columns having a B-shaped cross section, and end plates 10 and 10 are welded to the top and bottom of the prisms. A through hole penetrating in the vertical direction is formed in the upper and lower end plates of the column member, and nuts 11 and 11 are welded into the through hole, and the screw hole of the nut penetrates in the vertical direction. Eye bolts (not shown) are screwed onto the upper nuts, and the building unit 1 is lifted with a crane or the like using the eye bolts fixed to the upper parts of the four column members 2, 2,. It is the composition which performs.

柱材２，２…の下端のエンドプレート１０内に固着されたナット１１には、柱材を基礎にアンカー固定するためのアンカー部材１５が螺合される。このアンカー部材１５は例えば鉄筋コンクリートを形成する鉄筋を所定長に切断し、一端部にねじ切りを行い、柱材２の下端部のナット１１に螺合させて柱材の下方に鉛直方向に突出させる構成である。なお、アンカー部材は長ボルトを所定長に切断したものでもよい。   An anchor member 15 for fixing the anchor to the base of the pillar material is screwed to the nut 11 fixed in the end plate 10 at the lower end of the pillar materials 2, 2,. The anchor member 15 has a configuration in which, for example, a reinforcing bar forming reinforced concrete is cut into a predetermined length, one end is threaded, and is screwed into the nut 11 at the lower end of the column member 2 so as to protrude vertically below the column member. It is. The anchor member may be a long bolt cut to a predetermined length.

この建物ユニット１は、基礎２０上に載置固定され、複数の建物ユニット１を並置、あるいは積み重ねてユニット建物が構成される。基礎２０には、このアンカー部材１５が挿入されるアンカー穴２１が形成されている。アンカー穴２１は基礎コンクリートを打設後にドリル等で形成してもよく、打設時にシース管を埋め込んで形成してもよい。アンカー穴２１の直径はアンカー部材１５の直径より十分大きく設定され、その深さもアンカー部材１５の長さより十分大きく設定されている。アンカー部材１５は基礎２０のアンカー穴２１に挿入され、無収縮グラウトやモルタル等の充填材２２で基礎２０に固定される構成となっている。   The building unit 1 is placed and fixed on the foundation 20, and a plurality of building units 1 are juxtaposed or stacked to form a unit building. An anchor hole 21 into which the anchor member 15 is inserted is formed in the base 20. The anchor hole 21 may be formed with a drill or the like after the foundation concrete is placed, or may be formed by embedding a sheath tube at the time of placement. The diameter of the anchor hole 21 is set sufficiently larger than the diameter of the anchor member 15, and the depth thereof is also set sufficiently larger than the length of the anchor member 15. The anchor member 15 is inserted into the anchor hole 21 of the base 20 and is fixed to the base 20 with a filler 22 such as non-shrink grout or mortar.

建物ユニット１には、このユニットを基礎２０に埋め込まれたアンカーボルト２５で固定するため、アンカーボルトが挿入される貫通孔１２が形成されている。この貫通孔は補強プレート９と下梁３，４を貫通して形成されている。このように、基礎２０から突出するアンカーボルト２５が挿入される貫通孔１２は補強プレート９の下面板部と下梁４の下方リブの２枚の鋼材を貫通する構成であり、２枚の鋼板を貫通してナット２６で固定するため、建物ユニット１の基礎２０との固定は頑強に行うことができる構成となっている。アンカーボルト２５は基礎２０のＸ方向、及びＹ方向に沿って補強プレート９，９…を貫通する位置に設定されている。本実施の形態では、アンカーボルト２５は基礎２０のＹ方向、すなわち建物ユニット１の短辺方向に沿って埋設され、ナット２６で固定される構成となっている。   In the building unit 1, a through hole 12 into which the anchor bolt is inserted is formed in order to fix the unit with an anchor bolt 25 embedded in the foundation 20. The through hole is formed through the reinforcing plate 9 and the lower beams 3 and 4. Thus, the through-hole 12 into which the anchor bolt 25 protruding from the foundation 20 is inserted is configured to penetrate through the two steel materials of the lower surface plate portion of the reinforcing plate 9 and the lower rib of the lower beam 4, and the two steel plates Since it penetrates and is fixed with the nut 26, it has the structure which can be fixed firmly with the foundation 20 of the building unit 1. FIG. The anchor bolt 25 is set at a position that penetrates the reinforcing plates 9 along the X direction and the Y direction of the foundation 20. In the present embodiment, the anchor bolt 25 is embedded along the Y direction of the foundation 20, that is, along the short side direction of the building unit 1, and is fixed by the nut 26.

前記の如く構成された本実施形態の建物ユニットの固定構造の動作について以下に説明する。ユニット建物の構築に際し、建築現場に形成された基礎２０上に建物ユニット１を載置固定する。基礎２０には複数のアンカーボルト２５，２５…が埋め込まれ、基礎の上面から鉛直方向上方に突出している。また、基礎２０には、建物ユニット１の柱材２，２…が載置される部位にアンカー穴２１，２１…が凹んで形成されている。   The operation of the building unit fixing structure of the present embodiment configured as described above will be described below. When building the unit building, the building unit 1 is placed and fixed on the foundation 20 formed on the building site. A plurality of anchor bolts 25, 25... Are embedded in the base 20 and protrude upward in the vertical direction from the upper surface of the base. In addition, anchor holes 21, 21,... Are recessed in the base 20 at portions where the column members 2, 2.

建物ユニット１はクレーン等により四隅の柱材２，２…の上端に固定されたアイボルトにより吊上げられた状態で、柱材２，２…の下端のナット１１にアンカー部材１５をねじ込んで下方に突出した状態とする。次いで、基礎２０のアンカー穴２１に充填材２２として無収縮グラウトを注入し、充填材２２が固化する前に建物ユニット１を降下させ、アンカー部材１５を充填材の注入されたアンカー穴２１に挿入し、建物ユニット１を基礎２０上に載置する。建物ユニット１が基礎上に載置されると基礎２０から突出しているアンカーボルト２５は補強プレート９と下梁４とを貫通する貫通孔１２に挿入された状態となる。このあと、アンカーボルト２５に座金をはめ込み、ナット２６をねじ込んで建物ユニット１を基礎２０に固定する。   The building unit 1 protrudes downward by screwing an anchor member 15 into the nut 11 at the lower end of the pillars 2, 2, while being lifted by eyebolts fixed to the upper ends of the pillars 2, 2. It will be in the state. Next, non-shrink grout is injected into the anchor hole 21 of the foundation 20 as the filler 22, the building unit 1 is lowered before the filler 22 solidifies, and the anchor member 15 is inserted into the anchor hole 21 into which the filler has been injected. Then, the building unit 1 is placed on the foundation 20. When the building unit 1 is placed on the foundation, the anchor bolt 25 protruding from the foundation 20 is inserted into the through hole 12 that penetrates the reinforcing plate 9 and the lower beam 4. Thereafter, a washer is fitted into the anchor bolt 25 and a nut 26 is screwed to fix the building unit 1 to the foundation 20.

この状態で、アンカー穴２１に注入された充填材２２が固化すると、建物ユニット１は四隅の柱材２の下端がアンカー部材１５を介して基礎２０にアンカー固定されるとともに、柱材２からＹ方向に延出する補強プレート９と下梁４との接合部分がアンカーボルト２５及びナット２６で固定される。なお、柱材２からＸ方向に延出する補強プレート９と下梁３との接合部分も同様にアンカーボルトで固定するように構成してもよい。   In this state, when the filler 22 injected into the anchor hole 21 is solidified, the building unit 1 is anchored to the foundation 20 via the anchor members 15 at the lower ends of the pillars 2 at the four corners, A joint portion between the reinforcing plate 9 and the lower beam 4 extending in the direction is fixed by an anchor bolt 25 and a nut 26. In addition, you may comprise so that the junction part of the reinforcement plate 9 extended in the X direction from the pillar material 2 and the lower beam 3 may be similarly fixed with an anchor bolt.

このように建物ユニット１は、柱材２，２…の下端部がアンカー部材１５を介して固定されるとともに、柱材に近接するＹ方向の下梁部分、すなわち、補強プレート９と下梁３とが基礎２０に強固に固定されるため、建物ユニット１に外力が作用しても柱材に加わる浮き上がり力を小さくでき、建物ユニット１のＹ方向のフレーム耐力を向上させることができる。また、柱材２からＸ方向に延出する補強プレート９と下梁３との接合部分も同様にアンカーボルト２５で固定すれば、さらに建物ユニット１のＸ方向のフレーム耐力も向上させることができる。   In this way, the building unit 1 has the lower ends of the column members 2, 2... Fixed via the anchor member 15, and the lower beam portion in the Y direction adjacent to the column members, that is, the reinforcing plate 9 and the lower beam 3.
