【０００１】
【発明の属する技術分野】
本発明は、不陸天端を有する基礎スラブ上の土台レベル調整装置及び土台レベル調整方法に関する。
【０００２】
【従来の技術】
従来、不陸天端を有する基礎スラブ上の土台レベル調整には、例えば、図６（ａ）（ｂ）に示すように、基礎スラブ１の上面高さレベルが下がっているところと土台２との間に、別途形成した介在部材３，４を挿し込み、かつ、介在部材の挿し込まれていない空間にモルタルを充填することが行われていた。
【０００３】
【発明が解決しようとする課題】
ところが、上述した従来のような土台レベル調整の構成乃至方法は、微調整するには多種類の介在部材が現場で必要となり、作業が煩わしく、そのため、精度の良いレベル調整には、長い時間や熟練度を要し、コスト高となっていた。
【０００４】
本発明は、上記問題を解消するものであり、熟練度を要することなく、微調整や高精度な調整を容易かつ短時間で行え、低コスト化が図れる、基礎スラブ上の土台レベル調整装置及び土台レベル調整方法を提供することを目的とする。
【０００５】
【課題を解決するための手段及び発明の効果】
上記目的を達成するために本発明は、不陸天端を有する基礎スラブ上に載置される横架木からなる土台のレベル調整を行うための土台レベル調整装置であって、前記横架木の下面近傍に回転止め固定される鍔部と、この鍔部から立設され内壁面に雌ねじが形成された筒部とを有する固定部材と、
下面が前記基礎スラブ上に当接される鍔部と、この鍔部から立設され外壁面に前記雌ねじに螺合する雄ねじが形成され、この雄ねじ先端にねじ回転用の係合溝が設けられた柱部とを有する可動部材とを備え、
前記横架木に設けた上下貫通孔に下方から前記固定部材の筒部を挿入して鍔部を横架木に固定するとともに、その下方から前記雌ねじ内に前記可動部材の柱部の雄ねじを螺合させた状態とし、前記係合溝を用いて可動部材を回転させることにより可動部材を上下動させるものである。
【０００６】
本発明の土台レベル調整装置においては、同装置の固定部材及び可動部材を予め横架木に装着しておき、その横架木を基礎スラブ天端に載置した状態で、可動部材の係合溝を用いて可動部材を回転させることにより可動部材が上下動し、その鍔部が基礎スラブ天端に当接する。これにより、基礎スラブが不陸天端となっていて、その上に載置した横架木からなる土台と基礎スラブ上面との間に隙間が生じていても、容易に不陸天端の基礎スラブに対して土台を持ち上げることができる。従って、熟練度を要することなく、精度の良いレベル調整を短時間で低コストに行うことができる。
【０００７】
また、上記において、固定部材の鍔部には、横架木への止め釘を挿通させる孔が設けられ、可動部材の鍔部には、止め釘用の孔に対応する位置に該孔よりも大きな径の孔が設けられているものとしてもよい。この構成においては、固定部材と可動部材とを結合させ、固定部材の止め釘挿通孔と可動部材の孔とを合致させた状態とすることで、これら孔に止め釘を通して固定部材を横架木へ固定することができる。これにより、予め固定部材と可動部材とを横架木へ固定した状態としておくことで、現場における土台のレベル調整作業を迅速に行うことができる。
【０００８】
本発明は、不陸天端を有する基礎スラブ上に載置される横架木からなる土台のレベル調整を行う土台レベル調整方法において、
鍔部と、この鍔部から立設され内壁面に雌ねじが形成された筒部とを有する固定部材と、
鍔部と、この鍔部から立設され外壁面に前記雌ねじに螺合する雄ねじが形成され、この雄ねじ先端にねじ回転用の係合溝が設けられた柱部とを有する可動部材とを用い、
前記横架木には、上下貫通孔及びその下面側に座繰り孔が形成されており、
前記固定部材と前記可動部材とは、筒部の雌ねじに柱部の雄ねじを螺合させることにより両鍔部同士が重ね合わされるかたちで結合状態とされ、
前記横架木の上下貫通孔に下方から前記固定部材の筒部を挿通させ、かつ座繰り孔内に鍔部を埋設し、回転止め固定する工程と、
この結合状態の固定部材と可動部材を横架木に装着した土台を基礎スラブ上に配置する工程と、
前記土台の上面側から前記可動部材のねじ回転用の係合溝を介して該可動部材を回転させることにより、基礎スラブ天端に該可動部材の鍔部を突接させて土台を持ち上げてレベルを調整する工程とを有するものである。
【０００９】
本発明の方法においては、固定部材と可動部材を装着した横架木を基礎スラブ天端に載置した状態のまま、現場での簡単な作業により容易に精度の良いレベル調整を行うことができる。
【００１０】
【発明の実施の形態】
以下、本発明を具体化した実施形態について図面を参照して説明する。図１（ａ）（ｂ）は土台レベル調整装置の可動部材、（ｃ）（ｄ）は土台レベル調整装置の固定部材を示し、図２は同調整装置を横架木からなる土台に装着した状態を示し、図３は同調整装置を装着した横架木が基礎スラブ上に載置された状態を示す。このレベル調整装置１１は、基礎スラブが不陸天端を有する場合に、基礎スラブ上に載置される横架木（土台）１２の水平レベルを調整するためのものであり、横架木１２に固定される固定部材１３と、この固定部材１３に螺合結合され、高さ調整に供される可動部材１４とから成る。
【００１１】
まず、土台レベル調整装置１１の固定部材１３及び可動部材１４について説明する。固定部材１３及び可動部材１４は機械的強度の高い金属材料で構成されている。固定部材１３は、図１（ｃ）（ｄ）に示されるように、横架木へ回転止め固定される鍔部１３ａと、この鍔部１３ａから立設された筒部１３ｂとから成り、筒部１３ｂの内壁面には雌ねじ１３ｃが形成されている。鍔部１３ａは横架木の幅よりも小さな径の円板形とされ、横架木への止め釘が挿通される孔１３ｅが複数個、円周方向に分散して設けられている。
【００１２】
可動部材１４は、図１（ａ）（ｂ）に示されるように、下面が基礎スラブ天端に当接される鍔部１４ａと、この鍔部１４ａから立設された柱部１４ｂとから成り、柱部１４ｂの外壁面には上記雌ねじ１３ｃに螺合する雄ねじ１４ｃが形成され、この雄ねじ先端にねじ回転用の係合溝１４ｄが設けられている。鍔部１４ａは横架木の幅よりも小さな径の円板形とされ、孔１４ｅが複数個円周方向に分散して設けられている。この孔１４ｅは、上記固定部材１３の鍔部１３ａに設けられた孔１３ｅに対応する位置にあり、孔１３ｅよりも大きい径を持つ。かくして、可動部材１４は、高さ調整用キャスターにおけるレベル調整ボルトに、固定部材１３は調整ナットにそれぞれ相当する形態になっている。
【００１３】
次に、土台レベル調整装置１１の横架木１２への取付構成について説明する。図２に示されるように、横架木１２には、同調整装置１１を取り付けるための孔が形成されている。この取付孔としては、上下貫通孔１５と、この上下貫通孔１５の下面側に形成された座繰り孔１６、及び上面側に形成された座繰り孔１７がある。固定部材１３及び可動部材１４は、予め、固定部材１３の筒部１３ｂの雌ねじ１３ｃ内に、その下方から可動部材１４の柱部１４ｂの雄ねじ１４ｃを螺合させて、両鍔部１３ａ，１４ａ同士が重ね合わされるかたちで結合状態とされる。この状態の固定部材１３及び可動部材１４は、横架木１２の上下貫通孔１５内に下方から筒部１３ｂが挿入され、鍔部１３ａが横架木１２の座繰り孔１６内に固定される。
【００１４】
このとき、鍔部１３ａ，１４ａは座繰り孔１６内に入り込むので、レベル調整を行わないときに、調整装置１１が横架木１２の下面に突出して邪魔になるようなことがない。また、固定部材１３の止め釘挿通孔１３ｅと可動部材１４の孔１４ｅとを合致させた状態とし、これら孔を通して止め釘１８を横架木１２に打ち込むことにより、固定部材１３を横架木１２に固定することができる。なお、可動部材１４の孔１４ｅの径は、止め釘１８の頭部が挿通しうる大きさとする。
【００１５】
次に、土台レベル調整方法について図３を加えて説明する。基礎スラブ２１には予め横架木１２を固定するためのアンカーボルト２２が立設されており、このアンカーボルト２２に対応して横架木１２にはボルト挿通孔が形成されている。土台レベル調整装置１１は、例えば、９０×９０ｍｍの横架木１２に、例えば、１．０〜１．２ｍ間隔で予め設けられている。横架木１２への土台レベル調整装置１１の装着は、工場等で予め加工しておくことが望ましい。このように施工された横架木１２は、現場において基礎スラブ２１の天端に配置されて土台となり、アンカーボルト２２により仮固定される。そのとき、基礎スラブ２１が不陸天端となっていて、水平に載置されるべき横架木１２と基礎スラブ２１上面との間に隙間が生じる場合にレベル調整を行う。なお、可動部材１４としては、柱部１４ｂの高さ寸法が横架木１２の高さ寸法と同程度のものを用いればよく、また、固定部材１３としては、筒部１３ｂの高さ寸法が柱部１４ｂの１／２乃至１／３程度のものを用いればよい。
【００１６】
レベル調整は、可動部材１４の係合溝１４ｄにねじ回し等の工具を係合させて可動部材１４を回転させることにより行う。これにより、可動部材１４は下方に移動し、その鍔部１４ａが基礎スラブ２１の天端に当接し、基礎スラブ２１に対して土台を持ち上げるようになる。これにより、基礎スラブ２１が不陸天端となっていても、容易かつ短時間で精度の良いレベル調整を行うことができる。従って、レベル調整は、熟練度を要することもなく低コストに行うことができる。なお、従来一般の高さ調整用キャスターは、高さ調整のために下側面でねじを回す形態であるため、本発明のような基礎スラブ上での土台レベル調整には使用不能である。
【００１７】
こうしてレベル調整を行った後の処理として、横架木１２と基礎スラブ２１上面との隙間に、モルタル等の無機質系充填材を補充する。充填材の補充は、例えば、図４に示すように、塩化ビニール等の袋容器２５内で水と混練させた充填材を吐出用開口より必要部位に押し出すことで、行うことができる。袋容器２５の内部には、予め区画して充填材と水とが封入されており、作業直前に作業者が外部から圧力をかけて区画を破断することで、袋容器２５内で充填材と水とを混練させる。充填材は水と混練されると時間経過とともに硬化する。このような充填を行うことで、横架木１２と基礎スラブ２１上面との間に空間がなくなり、両者は面的に接するので、耐震強度が高くなる。
【００１８】
上記のような土台レベル調整方法の全体工程について図５を加えて以下に説明する。土台レベル調整工程では、まず、土台にレベル調整装置取付孔を形成し（Ｓ１１）、レベル調整装置１１を取付孔に釘止め固定し（Ｓ１２）、その後、土台を基礎スラブ２１上に配置する（Ｓ１３）。その後、可動部材１４のねじを回転して土台レベル調整を行い（Ｓ１４）、最期に、隙間に充填材を補充する（Ｓ１５）。
【００１９】
本発明は、上記実施例の構成に限られることなく、発明の趣旨を変更しない範囲で種々の変形が可能である。例えば、上記実施形態では、固定部材１３の横架木１２への固定に止め釘１８を用いる場合を示したが、止め釘を用いなくとも、固定部材１３に横架木１２との係合爪を設けた構成など、固定部材１３が横架木１２に対して回転止め固定できる構成としてもよい。

[0010]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described with reference to the drawings. 1 (a) and 1 (b) show a movable member of the base level adjusting device, FIGS. 1 (c) and (d) show a fixed member of the base level adjusting device, and FIG. 2 shows that the adjusting device is mounted on a base made of a horizontal bridge. The state is shown, and FIG. 3 shows a state in which the horizontal bridge mounted with the adjusting device is placed on the foundation slab. This level adjustment device 11 is for adjusting the horizontal level of the horizontal bridge (base) 12 placed on the foundation slab when the foundation slab has an uneven top, and is fixed to the horizontal bridge 12. And a movable member 14 that is screwed to the fixed member 13 and used for height adjustment.
[0011]
First, the fixed member 13 and the movable member 14 of the base level adjusting device 11 will be described. The fixed member 13 and the movable member 14 are made of a metal material having high mechanical strength. As shown in FIGS. 1 (c) and 1 (d), the fixing member 13 includes a flange portion 13 a that is fixed to the horizontal tree by rotation and a cylinder portion 13 b that is erected from the flange portion 13 a. A female screw 13c is formed on the inner wall surface of the portion 13b. The eaves portion 13a has a disk shape with a diameter smaller than the width of the horizontal tree, and a plurality of holes 13e through which the pegs to the horizontal tree are inserted are distributed in the circumferential direction.
[0012]
As shown in FIGS. 1A and 1B, the movable member 14 includes a flange portion 14a whose lower surface is in contact with the top end of the basic slab, and a column portion 14b that is erected from the flange portion 14a. A male screw 14c that engages with the female screw 13c is formed on the outer wall surface of the column portion 14b, and an engaging groove 14d for screw rotation is provided at the tip of the male screw. The flange portion 14a has a disk shape with a diameter smaller than the width of the horizontal tree, and a plurality of holes 14e are provided in the circumferential direction. The hole 14e is located at a position corresponding to the hole 13e provided in the flange 13a of the fixing member 13, and has a larger diameter than the hole 13e. Thus, the movable member 14 corresponds to the level adjusting bolt in the height adjusting caster, and the fixed member 13 corresponds to the adjusting nut.
[0013]
Next, the mounting configuration of the base level adjusting device 11 to the horizontal bridge 12 will be described. As shown in FIG. 2, a hole for attaching the adjusting device 11 is formed in the horizontal tree 12. As the mounting holes, there are an upper and lower through hole 15, a countersink hole 16 formed on the lower surface side of the upper and lower through hole 15, and a countersink hole 17 formed on the upper surface side. The fixed member 13 and the movable member 14 are preliminarily screwed into the female screw 13c of the cylindrical portion 13b of the fixed member 13 from the lower side of the male screw 14c of the column portion 14b of the movable member 14, so Are combined to form a combined state. In the fixed member 13 and the movable member 14 in this state, the cylindrical portion 13b is inserted into the vertical through hole 15 of the horizontal frame 12 from below, and the flange portion 13a is fixed in the counterbore 16 of the horizontal frame 12. .
[0014]
At this time, the flanges 13a and 14a enter the counterbore 16 so that when the level adjustment is not performed, the adjusting device 11 does not protrude from the lower surface of the horizontal tree 12 and become an obstacle. In addition, the peg insertion hole 13e of the fixed member 13 and the hole 14e of the movable member 14 are brought into alignment with each other, and the peg 18 is driven into the horizontal tree 12 through these holes, thereby fixing the fixed member 13 to the horizontal tree 12. Can be fixed to. The diameter of the hole 14e of the movable member 14 is set to a size that allows the head of the peg 18 to be inserted.
[0015]
Next, the base level adjustment method will be described with reference to FIG. Anchor bolts 22 for fixing the horizontal bridge 12 are erected in advance on the foundation slab 21, and bolt insertion holes are formed in the horizontal bridge 12 corresponding to the anchor bolts 22. The base level adjusting device 11 is provided in advance on, for example, a 90 × 90 mm horizontal bridge 12 at an interval of 1.0 to 1.2 m, for example. The mounting of the base level adjusting device 11 to the horizontal bridge 12 is preferably processed in advance at a factory or the like. The horizontal tree 12 thus constructed is placed at the top of the foundation slab 21 at the site and becomes a base, and is temporarily fixed by anchor bolts 22. At that time, the level adjustment is performed when the foundation slab 21 is at the top of the land and a gap is generated between the horizontal bridge 12 to be placed horizontally and the upper surface of the foundation slab 21. As the movable member 14, it is sufficient to use a column having the height dimension of the column portion 14 b that is substantially the same as the height dimension of the horizontal frame 12, and the fixing member 13 has a height dimension of the cylinder portion 13 b. What is about 1/2 to 1/3 of the column part 14b may be used.
[0016]
The level adjustment is performed by rotating the movable member 14 by engaging a tool such as a screwdriver with the engagement groove 14d of the movable member 14. As a result, the movable member 14 moves downward, and the collar portion 14 a comes into contact with the top end of the foundation slab 21 to lift the foundation with respect to the foundation slab 21. Thereby, even if the foundation slab 21 is a non-landscape top end, level adjustment with high accuracy can be performed easily and in a short time. Therefore, level adjustment can be performed at low cost without requiring skill. In addition, since the conventional general caster for height adjustment is a form which turns a screw | thread on a lower surface for height adjustment, it cannot be used for the foundation level adjustment on a foundation slab like this invention.
[0017]
As a process after the level adjustment is performed in this manner, an inorganic filler such as mortar is replenished in the gap between the horizontal bridge 12 and the upper surface of the foundation slab 21. For example, as shown in FIG. 4, the filler can be replenished by extruding a filler kneaded with water in a bag container 25 such as vinyl chloride from a discharge opening to a necessary portion. The inside of the bag container 25 is preliminarily partitioned and filled with a filler and water, and an operator applies pressure from outside to break the section immediately before the operation, so that the filler and Knead with water. When the filler is kneaded with water, it hardens over time. By performing such filling, there is no space between the horizontal tree 12 and the upper surface of the foundation slab 21, and both are in surface contact with each other, so that the seismic strength is increased.
[0018]
The overall process of the base level adjustment method as described above will be described below with reference to FIG. In the base level adjustment step, first, a level adjustment device mounting hole is formed in the base (S11), the level adjustment device 11 is fixed to the mounting hole with a nail (S12), and then the base is placed on the foundation slab 21 ( S13). Thereafter, the screw of the movable member 14 is rotated to adjust the base level (S14), and finally, the filler is replenished in the gap (S15).
[0019]
The present invention is not limited to the configuration of the above embodiment, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, the case where the nail 18 is used to fix the fixing member 13 to the horizontal tree 12 is shown, but the engaging nail with the horizontal tree 12 can be fixed to the fixing member 13 without using the nail. It is good also as a structure which can fix the fixing member 13 with respect to the horizontal tree 12 by rotation prevention, such as the structure provided.
