基礎型枠に組み込まれる鉄筋は、通常、上下の主筋や副筋、あばら筋等を予めユニット状に組み立てて基礎型枠支持具に載置されるが、かかる鉄筋ユニットは重量も非常に大きくなる。このような鉄筋ユニットを基礎型枠支持具上に据え付け、さらに型枠パネルも建て込んでから、それらの位置を基礎の幅方向に微調整したい場合、上記従来のような基礎型枠支持具では、基礎型枠支持具自体を鉄筋ユニットや型枠パネルとともに基礎下地面に沿って移動させるしかないので、鉄筋ユニットや型枠パネルの重量が負担になって、位置調整作業がきわめて困難になる。   Reinforcing bars that are built into the base formwork are usually placed on the base formwork support by assembling the upper and lower main bars, auxiliary bars, ribs, etc. into a unit shape in advance, but such a reinforcing bar unit is very heavy. . If such a reinforcing bar unit is installed on the base formwork support and the formwork panel is installed, and if you want to fine-tune their position in the width direction of the base, Since the base formwork support itself can only be moved along with the base unit surface together with the reinforcing bar unit and the formwork panel, the weight of the reinforcing bar unit and the formwork panel becomes a burden, and the position adjustment work becomes extremely difficult.

また、上記特許文献2記載の基礎型枠支持具のように、長く立ち上げたネジ軸の上方に下支持体を取り付けて、その支持位置よりも低い位置で重量の大きな鉄筋ユニットを受けるような構造では、ネジ軸に大きな曲げ荷重が作用して基礎型枠支持具の安定性が損なわれ、鉄筋ユニットを載置する際に基礎型枠支持具が倒れてしまうおそれがある。   Further, like the basic formwork support described in Patent Document 2, a lower support is attached above the long-running screw shaft, and a heavy reinforcing bar unit is received at a position lower than the support position. In the structure, a large bending load acts on the screw shaft to impair the stability of the base formwork support, and the base formwork support may fall when the reinforcing bar unit is placed.

また、上記従来の基礎型枠支持具は、鉄筋が上金具や下支持体に直接接触しているので、金属部分を介して鉄筋が基礎下地面と電気的に導通しており、したがって電気的には、鉄筋に対するコンクリートの被り厚さが全く確保されないことになる。すると、鉄筋に錆が発生しやすくなって、基礎の強度や耐久性が低減されるおそれがある。   Further, in the above-described conventional basic formwork support, since the reinforcing bars are in direct contact with the upper metal fitting and the lower supporting body, the reinforcing bars are electrically connected to the basic ground surface through the metal portion, and therefore, the electrical Therefore, the concrete covering thickness with respect to the reinforcing bars is not ensured at all. Then, it becomes easy to generate | occur | produce rust in a reinforcing bar, and there exists a possibility that the intensity | strength and durability of a foundation may be reduced.

本発明は上記のような着眼点からなされたもので、鉄筋ユニットを載置したときの安定性が高く、鉄筋ユニットを載置したままでの位置調整も容易で、さらに鉄筋を電気的に絶縁して錆を発生しにくくすることのできる基礎型枠支持具を提供するものである。   The present invention has been made from the viewpoint as described above, has high stability when the reinforcing bar unit is placed, can easily adjust the position while the reinforcing bar unit is placed, and further electrically insulate the reinforcing bar. Thus, it is intended to provide a base formwork support that can make it difficult to generate rust.

A reinforcing bar support having a hole is inserted into the both leg portions and is mounted on the position adjusting nut, and a fixing nut is screwed onto the leg portion from above, and is attached to the upper surface of the reinforcing bar support. An insulating sheet made of synthetic resin or synthetic rubber is polymerized, and a mold panel support made of a bar material bent in a substantially gate shape is erected on both ends of the reinforcing bar support, and the position adjusting nut The reinforcing bar support and the formwork panel support can be moved up and down along the legs by the operation of the fixing nut.

さらに本発明の基礎型枠支持具は、上記第一または第二の構成に係る基礎型枠支持具において、型枠パネル支持体の上面に型枠パネル支持片が設けられたことを特徴とする。   Furthermore, the basic formwork support of the present invention is characterized in that, in the basic formwork support according to the first or second configuration, a formwork panel support piece is provided on the upper surface of the formwork panel support. .

また、型枠パネル支持体の上面に型枠パネル支持片が設けられることにより、型枠パネルの位置決めが容易になり、型枠パネルの支持状態も安定する。   Further, by providing the formwork panel support piece on the upper surface of the formwork panel support, positioning of the formwork panel is facilitated and the support state of the formwork panel is stabilized.

以下、本発明の実施の形態について図を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図1〜図2は本発明の第一実施例を示す。図1は基礎型枠支持具の分解斜視図であり、図2は基礎型枠支持具の使用状態を示す側面図である。   1 to 2 show a first embodiment of the present invention. FIG. 1 is an exploded perspective view of a base formwork support, and FIG. 2 is a side view showing a use state of the base formwork support.

この基礎型枠支持具1Aは、台座21に立設された一対の脚部22に、位置調整用ナット23、鉄筋支持体24、絶縁シート25、ホルダ26、型枠パネル支持体27、固定用ナット28を取り付けて構成される。台座21は、基礎下地面F上に安定的に載置されうるものであれば特にその形態は問わないが、例示の形態では、矩形の鋼板の長辺側縁部に補強用のリブを上向きに形成した部材を利用している。   The basic formwork support 1A includes a pair of leg portions 22 erected on a pedestal 21, and a position adjusting nut 23, a reinforcing bar support body 24, an insulating sheet 25, a holder 26, a formwork panel support body 27, and a fixing body. It is configured by attaching a nut 28. The form of the pedestal 21 is not particularly limited as long as it can be stably placed on the foundation base surface F. However, in the illustrated form, a reinforcing rib faces upward on the long side edge of the rectangular steel plate. The member formed in is used.

脚部22は、寸切りボルトからなり、台座21の長辺方向(基礎の幅方向)に適宜の間隔を設けて配置され、脚部固定用のナット等を介して台座21に固定されている。各脚部22には、鉄筋支持体24を支承するための位置調整用ナット23が螺着され、適宜の高さに保持される。   The leg portion 22 is made of a slicing bolt, is arranged with an appropriate interval in the long side direction (the width direction of the foundation) of the pedestal 21, and is fixed to the pedestal 21 via a leg fixing nut or the like. . Each leg portion 22 is screwed with a position adjusting nut 23 for supporting the reinforcing bar support 24 and is held at an appropriate height.

鉄筋支持体24は、例えば図示のような断面L形のアングルピースからなり、その両端部近傍に脚部22を挿通可能な一対の通孔241が形成されている。この鉄筋支持体24は、頂面が平坦になるよう、リブを下に向けて脚部22に挿装され、位置調整用ナット23上に載架される。鉄筋支持体24の上面には、合成樹脂または合成ゴムからなる絶縁シート25が貼着されている。   The reinforcing bar support 24 is composed of, for example, an angle piece having an L-shaped cross section as shown in the figure, and a pair of through holes 241 through which the leg portions 22 can be inserted are formed in the vicinity of both ends thereof. The reinforcing bar support 24 is inserted into the leg portion 22 with the rib facing downward so that the top surface is flat, and is mounted on the position adjusting nut 23. An insulating sheet 25 made of synthetic resin or synthetic rubber is attached to the upper surface of the reinforcing bar support 24.

両脚部22における鉄筋支持体24よりも上方に突出した部分には、例えば筒状の鋼製パイプ等からなるホルダ26が挿装されている。両ホルダ26の長さは同じである。   A holder 26 made of, for example, a cylindrical steel pipe or the like is inserted into a portion of the both leg portions 22 protruding upward from the reinforcing bar support 24. Both holders 26 have the same length.

型枠パネル支持体27は、例えば図示のような両縁部にリブを有する断面溝形の鋼材からなり、鉄筋支持体24よりも長く形成されている。型枠パネル支持体27の中央部近傍には、脚部22を挿通可能な位置に、長手方向(基礎の幅方向)に延びる長孔271が形成されている。例示の形態では、長孔271は、各脚部22の位置に合わせて二箇所に分かれいるが、両略部22を挿通させうるように一体に連続していてもよい。   The formwork panel support 27 is made of a steel material having a cross-sectional groove shape having ribs on both edges as shown in the figure, for example, and is formed longer than the reinforcing bar support 24. In the vicinity of the center portion of the formwork panel support 27, a long hole 271 extending in the longitudinal direction (the width direction of the foundation) is formed at a position where the leg portion 22 can be inserted. In the illustrated embodiment, the long hole 271 is divided into two portions according to the position of each leg portion 22, but may be continuous integrally so that both the approximate portions 22 can be inserted.

この型枠パネル支持体27は、リブを下に向けて脚部22に挿装され、ホルダ26上に載架されて、さらにその上方から脚部22に固定用ナット28を螺着して固定される。型枠パネル支持体27おける両脚部22よりも外側に張り出した部分(張出部272)には、型枠パネルPの厚みや配置間隔と合致するように、上面の一部を切り起こして型枠パネル支持片273が形成されている。   The formwork panel support 27 is inserted into the leg portion 22 with the rib facing downward, is mounted on the holder 26, and is further fixed by screwing a fixing nut 28 onto the leg portion 22 from above. Is done. A part of the upper surface of the mold panel support 27 that protrudes outward from the legs 22 (projected part 272) is cut up and raised so as to match the thickness and arrangement interval of the mold panel P. A frame panel support piece 273 is formed.

この基礎型枠支持具1Aの使用方法は以下の通りである。まず、台座21に固定された両脚部22に位置調整用ナット23と鉄筋支持体24を装着した状態で、台座21を基礎下地面F上に載置する。そして、基礎の延設方向に適宜間隔で配置した複数個の基礎型枠支持具1Aについて、すべての鉄筋支持体24が基準の高さに、かつ水平となるように、、位置調整用ナット23の高さを調整する。   The usage method of this foundation mold support 1A is as follows. First, the pedestal 21 is placed on the foundation base surface F in a state in which the position adjusting nut 23 and the reinforcing bar support 24 are attached to both leg portions 22 fixed to the pedestal 21. Then, with respect to the plurality of foundation formwork supports 1A arranged at appropriate intervals in the extending direction of the foundation, the position adjusting nuts 23 are arranged so that all the reinforcing bar supports 24 are at the reference height and are horizontal. Adjust the height.

次いで、鉄筋(鉄筋ユニットの下主筋)Sを鉄筋支持体24に貼着された絶縁シート25上に載置する。鉄筋Sの載置後に必要があれば、さらに位置調整用ナット23を調整して、鉄筋Sのレベルを調整する。   Next, the reinforcing bar (the lower main reinforcing bar of the reinforcing bar unit) S is placed on the insulating sheet 25 attached to the reinforcing bar support 24. If necessary after the rebar S is placed, the position adjusting nut 23 is further adjusted to adjust the level of the rebar S.

鉄筋Sが正しく支持されたならば、各基礎型枠支持具1Aの脚部22にホルダ26と型枠パネル支持体27とを装着して、固定用ナット28により固定する。そして、型枠パネル支持体27の張出部272に型枠パネルPを載置して、鉄筋Sとともに図示しない支保工等により支保する。これにより、型枠パネルPも、所定の高さに支持される。   If the reinforcing bar S is correctly supported, the holder 26 and the formwork panel support 27 are attached to the leg portion 22 of each basic formwork support 1A and fixed by the fixing nut 28. And the formwork panel P is mounted in the overhang | projection part 272 of the formwork panel support body 27, and it supports by the support work etc. which are not shown in figure with the reinforcing bar S. Thereby, the formwork panel P is also supported at a predetermined height.

もし、この段階で、鉄筋S及び型枠パネルPが基礎の通りに対して幅方向にずれている場合には、固定用ナット28を緩め、型枠パネル支持体27を長孔272に沿って基礎の幅方向に摺動させながら通りの調整を行う。鉄筋S及び型枠パネルPが正しく設置されたならば、再度、固定用ナット28を締着して型枠パネル支持体27を固定する。   If the reinforcing bar S and the formwork panel P are displaced in the width direction with respect to the foundation at this stage, the fixing nut 28 is loosened and the formwork panel support 27 is moved along the long hole 272. Make the adjustments while sliding in the width direction of the foundation. If the reinforcing bar S and the formwork panel P are correctly installed, the formwork panel support 27 is fixed by fastening the fixing nut 28 again.

図3〜図4は本発明の第二実施例を示す。図3は基礎型枠支持具の分解斜視図であり、図4は基礎型枠支持具の使用状態を示す側面図である。   3 to 4 show a second embodiment of the present invention. FIG. 3 is an exploded perspective view of the base formwork support, and FIG. 4 is a side view showing a use state of the base formwork support.

この実施例に係る基礎型枠支持具1Bは、台座21に立設された一対の脚部22に、位置調整用ナット23及び固定用ナット28を介して鉄筋支持体24が取り付けられ、この鉄筋支持体24に型枠パネル支持体27が取り付けられている。   In the basic formwork support 1B according to this embodiment, a reinforcing bar support 24 is attached to a pair of legs 22 erected on a pedestal 21 via a position adjusting nut 23 and a fixing nut 28. A formwork panel support 27 is attached to the support 24.

台座21は、第一実施例に係る基礎型枠支持具1Aの台座21と特に差異はなく、寸切りボルトからなる脚部22も第一実施例と同様にして台座21に立設されているが、脚部22の配置間隔は第一実施例よりも広く、脚部22の長さは第一実施例よりも短く形成されている。
鉄筋支持体24は、第一実施例の型枠パネル支持体27と同様の部材、つまり両縁部にリブを有する断面溝形の鋼材からなり、脚部22を挿通可能な位置に、長手方向(基礎の幅方向)に延びる長孔242が形成されている。そして、リブを下に向けて脚部22に挿装され、位置調整用ナット23上に載架されて、さらにその上方から脚部22に螺着した固定用ナット28により固定される。鉄筋支持体24の上面のうち、少なくとも鉄筋Sに接触する中央部近傍には、合成樹脂または合成ゴムからなる絶縁シート25が貼着されている。
The pedestal 21 is not particularly different from the pedestal 21 of the basic formwork support 1A according to the first embodiment, and the leg portion 22 made of a cutting bolt is also erected on the pedestal 21 in the same manner as in the first embodiment. However, the arrangement | positioning space | interval of the leg part 22 is wider than the 1st Example, and the length of the leg part 22 is formed shorter than the 1st Example.
The reinforcing bar support 24 is made of a member similar to the formwork panel support 27 of the first embodiment, that is, made of a steel material having a cross-sectional groove shape having ribs on both edges, and in a longitudinal direction at a position where the leg portion 22 can be inserted. A long hole 242 extending in the width direction of the foundation is formed. And it is inserted in the leg part 22 with the rib facing downward, mounted on the position adjusting nut 23, and further fixed by a fixing nut 28 screwed onto the leg part 22 from above. An insulating sheet 25 made of a synthetic resin or a synthetic rubber is attached to the upper surface of the reinforcing bar support 24 in the vicinity of at least the central portion that contacts the reinforcing bar S.

型枠パネル支持体27は、例えば図示のような略門形に折曲された棒材からなり、鉄筋支持体24の両端部の上面に、脚部22を跨ぐようにして立設されている。型枠パネル支持体27の頂面には、型枠パネルPの厚み配置間隔と合致するように、型枠パネル支持片273が突設されている。   The formwork panel support 27 is made of, for example, a rod bent into a substantially gate shape as shown in the figure, and is erected on the upper surfaces of both ends of the reinforcing bar support 24 so as to straddle the leg portions 22. . On the top surface of the formwork panel support 27, a formwork panel support piece 273 protrudes so as to coincide with the thickness arrangement interval of the formwork panel P.

この基礎型枠支持具1Bの使用方法も、上記第一実施例に係る基礎型枠支持具1Aとほぼ同様である。すなわち、両脚部22に位置調整用ナット23と鉄筋支持体24を装着した状態で、台座21を基礎下地面F上に載置し、鉄筋支持体24の高さ及び水平を調整して、固定用ナット28を締着する。そして、鉄筋Sを鉄筋支持体24に貼着した絶縁シート25上に載置する。続いて、型枠パネル支持体27に型枠パネルPを載置し、鉄筋Sとともに図示しない支保工等により支保する。鉄筋S及び型枠パネルPが基礎の通りに対して幅方向にずれている場合には、固定用ナット28を緩め、鉄筋支持体24を長孔242に沿って基礎の幅方向に摺動させながら通りの調整を行う。これにより、鉄筋S及び型枠パネルPが正しく支持される。   The method of using the basic formwork support 1B is also substantially the same as the basic formwork support 1A according to the first embodiment. That is, with the position adjusting nut 23 and the reinforcing bar support 24 mounted on both legs 22, the pedestal 21 is placed on the foundation base surface F, and the height and level of the reinforcing bar support 24 are adjusted and fixed. The nut 28 is tightened. Then, the reinforcing bar S is placed on the insulating sheet 25 adhered to the reinforcing bar support 24. Subsequently, the formwork panel P is placed on the formwork panel support 27, and is supported together with the reinforcing bars S by a support work (not shown).
