Description

【０００１】
【発明の属する技術分野】
本発明は、建築物の基礎施工下地面に据付施工するＰＣ基礎部材の据付位置を所定の位置に合わせ、ＰＣ基礎部材の天端の高さを揃えると共に、その建ち具合を垂直に揃えるＰＣ基礎部材据付位置調整治具に関するものである。
【０００２】
【従来の技術】
従来、ＰＣ基礎部材の据付位置を所定の位置に合わせる据付位置の調整と、天端の高さを揃えるレベル調整と、建ち具合を垂直に揃える建ち具合調整は、図１９に図示する如く、仮置きした基礎施工下地面１２とＰＣ基礎部材１１の間の隙間に大型バール１０の先端を差し込み、その大型バール１０をテコにして前後左右に、或いは、上下に振り動かし、その都度ＰＣ基礎部材１１の据付位置や建ち具合を目視確認して行っている。
【０００３】
【発明が解決しようとする課題】
この大型バールを用いた従来のＰＣ基礎部材据付位置調整方法では、ＰＣ基礎部材が高重量物なので据付位置の調整に多大な労力を要し、大型バールを力まかせに大きく振り動かさなければＰＣ基礎部材が移動しないので、大型バールの振り動かし方を加減してＰＣ基礎部材の据付位置を微調整することが難しい。
【０００４】
又、ＰＣ基礎部材のレベルを揃えると建ち具合具合や並び具合に不揃いが生じ、並び具合を揃えるとレベルや建ち具合に不揃いが生じ、ＰＣ基礎部材のレベルと建ち具合と並び具合が同時に揃うまでには何回も大型バールを振り動かし、その振り動かす度にレベルと建ち具合と並び具合をそれぞれ目視確認しなければならないので、ＰＣ基礎部材据付位置調整に手間取る。
【０００５】
そして、ＰＣ基礎部材の据付位置の調整は、ＰＣ基礎部材の一端を調整してから他端を調整すると言うように、一端づつ行うのであるが、その一端の位置調整をし終えてから他端の位置調整を行うとき、先にし終えた一端でのレベルや建ち具合に不揃いが生じて再度調整し直さなければならなくなるようなことが起こるため、基礎部材施工下地面に配列する全てのＰＣ基礎部材の位置調整が完了するまでには相当の時間を要する。
【０００６】
ＰＣ基礎部材据付下地面の捨てコンクリートが薄く軟弱になっているときは、大型バールを介して作用するＰＣ基礎部材の重量によって基礎施工下地面に亀裂や窪みが出来、大型バールによるＰＣ基礎部材の移動が困難になり、その大型バールを振り動かすには、大型バールの長さと作業員が立ち廻れるだけの余裕のあるスペースを必要とする。しかし、建築現場によってはそれほど広いスペースがない場合もあり、そのような場合は狭い箇所で無理な姿勢で作業せざるを得なくなるので危険を伴うことになる。
【０００７】
そして、大型バールを用いたＰＣ基礎部材の据付位置の調整においては、据付位置調整時にＰＣ基礎部材が浮き上がってしまうこともあり、そのときＰＣ基礎部材が転倒する危険があり、動かそうとするＰＣ基礎部材の足元（大型バールをかける箇所）が不安定で反力がとれない場合もあり、クレーンを使用して吊り上げて微調節をするには余分な時間とコストが発生する。
【０００８】
【発明の目的】
本発明は、ＰＣ基礎部材据付位置の下地面の良し悪しに影響されず、据付位置の調整時にはＰＣ基礎部材の天端のレベルが変わったり建ち具合が損なわれず、建ち具合の調整時には据付位置が変わってしまわず、建ち具合と据付位置と天端の高さの各調整をそれぞれ切り離して行うことが出来、且つ、迅速確実にＰＣ基礎部材の据付位置と建ち具合と天端の高さを調整し得るようにすることを目的とする。

【００１６】
【発明の実施の形態】
図１〜図１８は、本発明の実施の形態を図示するものである。
【００１７】
【第１実施例】
即ち、図１〜９は、本発明の第１実施例に係るＰＣ基礎部材据付位置調整治具１９を図示するものであり、底裏から球面の一部が突き出ている球体１３に支えられる２個ペアーのフリーベアリング治具１４・１５と、そのフリーベアリング治具１４・１５を戴承するレベル調整板１６と、そのレベル調整板１６を戴承する定板１７とによってＰＣ基礎部材据付位置調整治具１９が構成されている。
【００１８】
レベル調整板１６には高さ調整ボルト１８が螺着されており、高さ調整ボルト１８の下端はレベル調整板１６の底裏から出没可能になっている。
【００１９】
ペアーになっている２個の各フリーベアリング治具１４・１５の底面からは、複数個の球体１３の球面の一部が突き出ている。フリーベアリング治具１４・１５の上面は、平板なＰＣ基礎部材戴承面２１になっており、その平板な上面２１からは、ＰＣ基礎板１１の側面に当接する舌片２２が突き出ている。
【００２０】
ＰＣ基礎部材据付位置調整治具１９は、図２と図４と図５に図示する如く、まず、定板１７を下地面１２に戴設し、その定板１７の上に高さ調整ボルト１８の下端を向けてレベル調整板１６を戴承し、そのレベル調整板１６の上にフリーベアリング治具１４・１５を載設して下地面１２に仮置きされる。
【００２１】
ＰＣ基礎部材１１は、ＰＣ基礎部材据付位置調整治具１９の上に吊り降ろされるが、そのとき舌片２２と舌片２２の間にＰＣ基礎部材１１が挟み込まれるようにフリーベアリング治具１４・１５をＰＣ基礎部材１１とレベル調整板１６の間に挟み込む。
【００２２】
図６〜図９は、ＰＣ基礎部材据付位置調整治具１９によってＰＣ基礎部材１１の据付位置と建ち具合とレベルを調整する手順を図解説明するものであり、ＰＣ基礎部材１１をフリーベアリング治具１４・１５に載設した状態において、高さ調整ボルト１８を回してレベル調整板１６と定板１７の間の隙間を拡縮加減してＰＣ基礎部材１１とのレベルと建ち具合を調整する。
【００２３】
次に、ＰＣ基礎部材据付箇所に張られた水糸（図示せず）に合わせて、ＰＣ基礎部材１１をレベル調整板１４の上でフリーベアリング治具１４・１５と共に移動して所定の据付位置に合わせる。
このようにして据付位置と建ち具合とレベルを調整してから、下地面１２とＰＣ基礎部材１１の間に所定の部材を挟み込んでＰＣ基礎部材１１を固定する。
【００２４】
例えば、図示する如く、下端に下向きにボルト２７が突き出た支持金物２８が取り付けられているＰＣ基礎部材１１では、下地面１２のボルト２７の下に位置する箇所に敷モルタル２９を盛り上げ（図７）、その敷モルタル２９の上に敷鉄板３０を載設し（図８）、必要に応じて敷鉄板３０を叩いて敷モルタル２９を固め、ボルト２７を回して敷鉄板３０を敷モルタル２９に圧着し（図９）、そのまま敷モルタル２９を固化させる。
【００２５】
その後、ＰＣ基礎部材据付位置調整治具１９は、敷モルタル２９が固化してから、高さ調整ボルト１８を回し、レベル調整板１６と定板１７の間の隙間を縮めてフリーベアリング治具１４・１５を降下させ、ＰＣ基礎部材１１と下地面１２の間の隙間から、フリーベアリング治具１４・１５とレベル調整板１６と定板１７を取り外すことになる。
【００２６】
レベル調整板１６の上面には、図１０に図示する如く、気泡管２０を付設しておき、その気泡管２０の気泡の位置を見ながら高さ調整ボルト１８を回して、下地面１２に仮置きしたレベル調整板１６の上面を水平に揃えておくとよい。
【００２７】
【第２実施例】
図１１〜１３は、本発明の第２実施例に係るＰＣ基礎部材据付位置調整治具１９を図示するものであり、ＰＣ基礎部材据付位置調整治具１９は、底裏から球面の一部が突き出ている球体１３に支えられる２個ペアーのフリーベアリング治具１４・１５と、そのフリーベアリング治具１４・１５を戴承するレベル調整板１６と、そのレベル調整板１６を戴承する定板１７とによってＰＣ基礎部材据付位置調整治具１９が構成され、レベル調整板１６には高さ調整ボルト１８が螺着されており、高さ調整ボルト１８の下端はレベル調整板１６の底裏から出没可能になっている。
【００２８】
フリーベアリング治具１４・１５の上面からは、３個の高さの揃った突起２３が突き出ており、それらの突起２３の頂端がＰＣ基礎部材戴承面２１を形成している。
また、フリーベアリング治具１４・１５の上面からは、ＰＣ基礎部材１１の側面に当接する舌片２２が、それらの突起２３よりも高く突き出ている。
【００２９】
２個ペアーとなるフリーベアリング治具１４・１５は、それらの球体１３と１３を角型リング２５の開口２４に入れ、その角型リング２５によってそれらの球体１３と１３を囲んで、レベル調整板１６に戴設される。
【００３０】
このように、２個のフリーベアリング治具１４・１５は、それらの球体１３の突き出ている部分をリング２５の開口２４に嵌め込んで連結した状態でレベル調整板１６の上に載設されるので、レベル調整板１６の上でＰＣ基礎部材１１を移動して据付位置を調整する過程において、２個のフリーベアリング治具１４・１５の間が広がってフリーベアリング治具１４・１５がＰＣ基礎部材１１の下端から外れることはない。
【００３１】
また、第２実施例に係るフリーベアリング治具１４・１５の如く、数個の突起２３をフリーベアリング治具１４・１５の上面に突設しておくと、スターラップ筋３１や下端主筋３２がＰＣ基礎部材１１の下端から突き出ていても、ＰＣ基礎部材１１をＰＣ基礎部材据付位置調整治具１９の上に吊り降ろす際に、スターラップ筋３１や下端主筋３２がレベル調整板１６に突き当たらない。
即ち、突起２３は、ＰＣ基礎部材１１とＰＣ基礎部材据付位置調整治具１９との間のスペーサーの役をなすものであり、フリーベアリング治具１４・１５の上面に取り外し自在に突設し、その高さはスターラップ筋３１の突出長さに応じて設定される。
【００３２】
第２実施例に係るＰＣ基礎部材据付位置調整治具１９は、第１実施例に係るＰＣ基礎部材据付位置調整治具と同様に使用され、ＰＣ基礎部材１１をフリーベアリング治具１４・１５に載設した状態において、高さ調整ボルト１８を回してレベル調整板１６と定板１７の間の隙間を拡縮加減してＰＣ基礎部材１１とのレベルと建ち具合が調整される。
【００３３】
【第３実施例】
図１４〜１８は、本発明の第３実施例に係るＰＣ基礎部材据付位置調整治具１９を図示するものであり、ＰＣ基礎部材据付位置調整治具１９は、底裏から球面の一部が突き出ている球体１３に支えられる２個ペアーのフリーベアリング治具１４・１５と、そのフリーベアリング治具１４・１５を戴承するレベル調整板１６と、そのレベル調整板１６を戴承する定板１７とによってＰＣ基礎部材据付位置調整治具１９が構成され、レベル調整板１６には高さ調整ボルト１８が螺着されており、高さ調整ボルト１８の下端はレベル調整板１６の底裏から出没可能になっている。
【００３４】
２個のフリーベアリング治具１４・１５のうちの一方のフリーベアリング治具１４の底裏には、他方のフリーベアリング治具１５が嵌合する嵌合溝２６が形成されている。
その嵌合溝２６の長さ方向は、その嵌合溝２６を有するフリーベアリング治具１４の２個の球体１３ａ・１３ｂの配列方向に平行になっている。
これら２個のフリーベアリング治具１４・１５は、その一方１４の嵌合溝２６に他方１５を嵌め込んでレベル調整板１６の上に載設される。
【００３５】
第３実施例に係るＰＣ基礎部材据付位置調整治具１９は、第１実施例に係るＰＣ基礎部材据付位置調整治具と同様に使用され、ＰＣ基礎部材１１をフリーベアリング治具１４・１５に載設した状態において、高さ調整ボルト１８を回してレベル調整板１６と定板１７の間の隙間を拡縮加減してＰＣ基礎部材１１とのレベルや建ち具合が調整される。
【００３６】
第３実施例に係るＰＣ基礎部材据付位置調整治具１９では、２個のフリーベアリング治具１４・１５が、その一方１４の嵌合溝２６に他方１５を嵌め込んでレベル調整板１６の上に載設されるので、２個のフリーベアリング治具１４・１５の間隔が広がって、ＰＣ基礎部材１１を移動する過程でＰＣ基礎部材１１から外れることがないと言う利点がある。
【００３７】
また、スターラップ筋３１に接合された下端主筋３２が下端から突き出ているＰＣ基礎部材１１に使用する場合には、その一方１４の嵌合溝２６の突き出ている部分を下端主筋３２とＰＣ基礎部材１１の間の隙間に差し込み、その突き出された嵌合溝２６に他方のフリーベアリング治具１４・１５を嵌め合わせて２個のフリーベアリング治具を組み立てることが出来、下端主筋３２が突き出たＰＣ基礎部材１１のレベルや建ち具合の調整に好都合である。
【００３８】
【発明の効果】
上記の通り本発明では、フリーベアリング治具１４・１５に載せてＰＣ基礎部材１１を移動し得るので、ＰＣ基礎部材１１の位置調整がし易く、且つ、建ち具合や天端のレベル調整も高さ調整ボルト１８を回して行えるので調整し易い。
【００３９】
そして、ＰＣ基礎部材据付位置調整治具１９が、フリーベアリング治具１４・１５とレベル調整板１６と定板１７とによって組み立てられるセパレート式になっているので、ＰＣ基礎部材１１の下端からスターラップ筋３１や下端主筋３２が突き出ていても、それらスターラップ筋３１や下端主筋３２を避けて使用することが出来る。
【００４０】
このように、本発明では、ＰＣ基礎部材据付位置調整治具１９にフリーベアリング（１４・１５）を使用しているのでＰＣ基礎部材１１のような重量物でも楽に位置調整が出来、高さ調整ボルト１８によってキメ細かいレベル調整が可能となり、大型バール等で力を入れてＰＣ基礎部材１１を動かさなくても位置調整が出来る。従って、ＰＣ基礎部材据付位置の下地面の良し悪しに影響されず、据付位置の調整時にはＰＣ基礎部材の天端のレベルが変わったり建ち具合が損なわれず、建ち具合の調整時には据付位置が変わってしまわず、建ち具合と据付位置と天端の高さの各調整をそれぞれ切り離して行うことが出来る。そこで、ＰＣ基礎部材１１の据付が安全、確実、且つ、迅速に出来る。
【００４１】
また、位置や建ち具合や天端のレベル調整時に、クレーンによってＰＣ基礎部材１１を吊り上げる必要がなく、クレーンはただＰＣ基礎部材１１を下地面１２に仮置きする場合にだけ使用すればよいので、クレーンの使用料が安くつき経済的である。

BACKGROUND OF THE INVENTION
The present invention relates to a PC foundation in which the installation position of a PC foundation member to be installed on a foundation foundation surface of a building is aligned with a predetermined position, the height of the top of the PC foundation member is aligned, and the building condition is aligned vertically. The present invention relates to a member installation position adjusting jig.
[0002]
[Prior art]
Conventionally, as shown in FIG. 19, the adjustment of the installation position for adjusting the installation position of the PC base member to a predetermined position, the level adjustment for aligning the height of the top end, and the adjustment for adjusting the vertical alignment of the building are temporarily performed. The tip of the large bar 10 is inserted into the gap between the foundation work foundation surface 12 and the PC foundation member 11 placed, and the large bar 10 is used as a lever to swing back and forth, left and right, or up and down. This is done by visually checking the installation position and building condition.
[0003]
[Problems to be solved by the invention]
In the conventional PC base member installation position adjustment method using this large bar, since the PC base member is heavy, a large amount of labor is required to adjust the installation position. Since it does not move, it is difficult to finely adjust the installation position of the PC base member by adjusting how the large bar is swung.
[0004]
Also, if the PC foundation member level is aligned, the building condition and alignment will be uneven, and if the alignment is aligned, the level and building condition will be uneven, until the PC foundation member level and building condition are aligned at the same time In this case, the large bar must be swung many times, and the level, building condition, and alignment must be visually checked each time the bar is swung, so it takes time to adjust the PC base member installation position.
[0005]
And the adjustment of the installation position of the PC foundation member is performed one end at a time so that the other end is adjusted after adjusting one end of the PC foundation member. When adjusting the position of the PC, all the PC foundations arranged on the foundation member construction ground surface will occur because the level at one end and the condition of the building will be uneven and will have to be adjusted again. It takes a considerable amount of time to complete the position adjustment of the member.
[0006]
When the discarded concrete on the foundation surface of the PC foundation member is thin and soft, the foundation foundation surface is cracked or dented due to the weight of the PC foundation member acting through the large bar. It becomes difficult to move, and in order to swing the large bar, the length of the large bar and a space enough for workers to go around are required. However, depending on the construction site, there may not be such a large space. In such a case, it is necessary to work in an unreasonable posture in a narrow part, which is dangerous.
[0007]
In the adjustment of the installation position of the PC foundation member using the large bar, the PC foundation member may be lifted during the adjustment of the installation position. In some cases, the foot of the base member (the place where the large bar is applied) is unstable and the reaction force cannot be obtained, and it takes extra time and cost to lift and fine-tune using a crane.
[0008]
OBJECT OF THE INVENTION
The present invention is not affected by the quality of the lower ground of the PC foundation member installation position, the top level of the PC foundation member is not changed or the building condition is not impaired when the installation position is adjusted, and the installation position is not adjusted when the building condition is adjusted. Without changing, each adjustment of the building condition, installation position and top edge height can be performed separately, and the installation position, building condition and ceiling height of the PC base member can be adjusted quickly and reliably. The purpose is to make it possible.
