【0002】
【従来の技術】
上記法面の地盤強化乃至安定化を図って、法面に格子状に法枠形成用の型枠を設置し、この型枠内にモルタルまたはコンクリートを打設して法枠を形成するのであるが、この型枠は種々の部材によって構成されており、例えば、左右一対の所要数の網状の側枠、所要本数の主鉄筋及びこれらを長手方向に連結するために所要の間隔を保って法面に立設される、スペーサーとしての機能も有する複数の型枠筋並びにこの型枠筋に嵌入された各主鉄筋を確実に保持するための鉄線等により構成されている。

【発明が解決しようとする課題】
上記特許文献1には、スターラップを用いずに主鉄筋を配筋する場合の一事例が開示されており,また,上記特許文献2、3には、スターラップを用いて主鉄筋を配筋する場合の各事例が開示されているが、いづれの場合もワイヤ、その他の結束手段を用いて、多数の個所で主鉄筋を結束しなければならないため、その結束作業に煩雑な手間と多くの時間を要し、能率的に主鉄筋を配筋できないという大きな問題があった。
【0006】
本発明は、上記の問題を解決することを課題として開発されたもので、結束手段を殆ど用いないで、主鉄筋を型枠筋に容易、確実に配筋できて、極めて能率的に法枠の型枠を形成できる、構造が簡単で、施工能率を著しく向上できる側枠付き型枠筋を提供することを目的とする。
【0007】
【課題を解決するための手段】
上記の課題を解決し、その目的を達成する手段として、本発明は、所要の間隔を保たせて上下に配置した少なくとも2本の横筋と、この横筋の左右両側の内側に該横筋と交差させて配置した少なくとも1本づつの縦筋と、上記横筋の両側に配置される所要長さの側枠とから構成されており、上記縦筋を上記の各交差部で横筋に固着して型枠筋本体を形成し、この型枠筋本体の上下2本の横筋と各縦筋との各交差部の近傍に、主鉄筋を嵌入するための嵌入部をそれぞれ設け、この型枠筋本体の複数を所要の間隔を保たせて対向配設すると共に、この対向配設した型枠筋本体の両側に上記側枠を取付けて構成した法枠の型枠形成用の側枠付き型枠筋を提供するものである。
【0008】
また、本発明は、上記のように構成した法枠の型枠形成用の側枠付き型枠筋において、横筋の左右両側に設けられた縦筋は、1本づつの縦筋から成り、各縦筋の上下両端部には屈曲部が設けてあり、また、主鉄筋の各嵌入部は、上下に配置した2本の横筋と各縦筋の屈曲部とにより囲まれた、端部に主鉄筋の嵌入ガイド部を有するスペースによりそれぞれ構成されている法枠の型枠形成用の側枠付き型枠筋を提供するものである。
【0009】
さらに、本発明は、前記のように構成した法枠の型枠形成用の側枠付き型枠筋において、横筋の左右両側に設けられた縦筋は、それぞれ2本づつを配置した縦筋群から成り、この縦筋群の各縦筋の上下両端部には屈曲部が設けてあり、また、主鉄筋の各嵌入部は、上下に配置した2本の横筋と上記複数の縦筋群の各縦筋の屈曲部とにより囲まれた、端部に主鉄筋の嵌入ガイド部を有するスペースによりそれぞれ構成されている法枠の型枠形成用の側枠付き型枠筋を提供するものである。
【0010】
以下に、本発明に係る法枠の型枠形成用の側枠付き型枠筋の実施の形態を添付図面に基づいて説明する。
図1〜図3は第1の実施の形態を示しており、この型枠付き型枠筋は、型枠筋本体1と、この型枠筋本体1に設けた後述する主鉄筋の嵌入部2と、この型枠筋本体1の両側に取り付けた後述する側枠3とにより構成されている。
【0011】
而して、上記型枠筋本体1は、後述する主鉄筋を支持できる強度を有する細目の鉄筋から成る下記構造の上下2本の横筋4、4と、この横筋4、4の両側に配置される同じ鉄筋から成る下記構造の1づつの縦筋5、5とから構成されている。
【0012】
上記2本の横筋4、4は、図3に示すように、両端にフック状の枢着体4a、4aをそれぞれ設けて構成されており、上記の縦筋5、5は、この実施の形態では、上下の両端部を、図1に示すように、横方向(イ)、上下方向(ロ)、斜め上下方向(ハ)に連続的に屈曲して、上下に略々横向きS字状の屈曲部5a、5aを設けて構成されている。
【0013】
上記のように構成した所要長さの2本の横筋4、4を上下に平行に配置し、この横筋4、4の左右両側の内側に寄った位置において、上記縦筋5、5を、その屈曲部5a、5aをそれぞれ内側に向けて直交状に交差させ、且つ、該屈曲部5a、5aを横筋4、4の上下から突出させて配置し、各交差部Pにおいて縦筋5、5を横筋4、4に固着して一つの型枠筋本体1Aを構成する。
【0014】
図2は、上記型枠筋本体1Aと所要の間隔を保たせて対向配置させて使用するいま一つの型枠筋本体1Bを示しており、上記型枠筋本体1Aと相違しているのは、縦筋5、5の屈曲部5a、5aを外側に向けて配置させた点のみであって、その他の部材の構成及び配置態様は全く同一であるから、それらの説明は省略する。
【0015】
次に、前記した主鉄筋の嵌入部2は、上記のように構成した各型枠筋本体1A、1Bにおける各2本の横筋4、4と、各縦筋5、5の突出した屈曲部5a、5aの1部とにより囲まれたスペース(空間部)で構成されており、具体的には、2本の横筋4、4と各縦筋5、5の4個所の交差部Pの外側において、横筋4の1部と、縦筋5の突出部と、該突出部から屈曲形成した屈曲部5aのうちの横方向(イ)、上下方向(ロ)の屈曲部とにより囲まれて形成されたスペースにより構成されており、各嵌入部2の端部には、各縦筋5、5の先端即ち、上記屈曲部5aのうちの斜め上下方向(ハ)の各屈曲部と各横筋4、4との間に、主鉄筋の嵌入ガイド部2aが設けられており、各嵌入部2と各嵌入ガイド部2aは連通されている。
【0016】
また、前記の側枠3は、この実施の形態では、例えば、図3に示すように、金属製の網で構成されており、上記のように構成した二つの型枠筋本体1A、1Bの高さと同一か、若干長い高さ寸法を備えると共に、型枠筋本体1A、1Bに配筋される主鉄筋の単位長さに応じて適宜に長さ寸法を設定できるものである。
【0017】
次に、上記のように構成した型枠筋本体1A、1Bの両側に二枚の側枠3を取付けて側枠付き型枠筋を構成するものであるが、この実施の形態では、例えば、所要の間隔を保って上記二つの型枠筋本体1Aと1Bを対向配設し、両型枠筋本体1A、1Bの上下の各横筋4、4の各突出端部に設けたフック状の枢着体4a、4aを介し、側枠3、3を枢着して側枠付き型枠筋を構成したものであり、この組立て作業は工場で行われるものであるが、この側枠付き型枠筋は枢着部を介して平らに折畳むことができ、その嵩を低くすることが可能である。
【0018】
上記のように構成した側枠付き型枠筋を使用して法枠を形成する場合は、折畳まれている側枠付き型枠筋を開いて、図3に略示するように地山G上の所要の個所に立設し、対向配置されている型枠筋本体1A、1Bの対向する上下、左右の各嵌入部2〜2内に、嵌入ガイド部2a〜2aを押し開いて所要長さの各主鉄筋6〜6を側方から嵌入するのであるが、嵌入された各主鉄筋6〜6は、押し開かれた嵌入ガイド部2a〜2aの復元により、何等の結束手段を用いることなく、無結束状態で確実に各嵌入部2〜2内に嵌入保持される。
【0019】
なお、各主鉄筋6〜6の嵌入順序は特に限定されないが、低位置に配置されている下方の各嵌入部2〜2内に主鉄筋6、6を嵌入した後に、上方の各嵌入部2〜2内に主鉄筋6、6を嵌入する方が作業の安全上からも好ましい。
【0020】
以上、本発明に係る側枠付き型枠筋を使用した法枠を形成するための一施工例について略述したが、この施工法を基本にして、図示していないが、法面に格子状に法枠形成用の型枠を形成配置し、この型枠内にモルタルまたはコンクリートを打設して法枠を形成するものである。
【0021】
上記の実施の形態で説明した側枠付き型枠筋によれば、各主鉄筋6〜6は各嵌入部2〜2内に確実に嵌入保持されるので、各主鉄筋6〜6を結束手段を用いることなく、無結束状態で確実に配筋でき、著しく容易且つ能率的に配筋できる利点があると共に、この側枠付き型枠筋は枢着体4aを介して平らに折畳んで嵩を縮小できるので、法枠の施工現場に容易に運搬できる利点がある。
【0022】
さらに、この側枠付き型枠筋本体1は、2本の横筋4、4と2本の縦筋5、5の合計4本の鉄筋のみで構成されているので、既述した従来技術に較べ構成が著しく簡単であって、安価且つ容易に製作できる多大な利点があると共に、対向配置された両型枠筋本体1A、1Bにおける対向する嵌入部2、2の各屈曲部5a・5aは、それぞれ反対側に設けられているので、各嵌入部2内の各主鉄筋6は、左右の両側から確実に保持される利点がある。
【0023】
図4及び図5は、本発明の第2の実施の形態を略示したものであり、上記第1の実施の形態と相違しているのは、両側の縦筋5、5を2本づつに倍増して縦筋群を形成し、所謂ダブルタイプに構成した点のみであって、その他の構成は第1の実施の形態と同一であるから、同一部分には符号を付すのを省略すると共に、同一の使用状態及び同一の作用、効果についての説明は省略する。
【0024】
この第2の実施の形態にしたがえば、主鉄筋6の使用本数を倍増できるので、法枠の強度を増大できる利点があるのみでなく、各側枠付き型枠筋の継足個所のみに増加した縦筋の各嵌入部2を利用して短い主鉄筋6〜6を嵌入することにより、各側枠付き型枠筋を確実に継足できる利点もある。
【0025】
図6及び図7は、本発明の第3の実施の形態を略示したものであって、上記第1の実施の形態と相違しているのは、両型枠筋本体1A、1Bの各縦筋5の下方の屈曲部5aを第1の実施の形態の屈曲部5aとは逆の方向に設けた点と、上下の横筋4、4の両側に1本づつの縦筋5、5を配設する際に、図示の態様で該横筋4、4に斜交させて配設した点のみである。
【0026】
即ち、各縦筋5の配設方向について説明すれば、図6に示す一方の型枠筋本体1Aの場合は、同図に向って左側の縦筋5を反時計回りの方向に傾斜させた状態で上下の横筋4、4に斜交固着すると共に、右側の縦筋5を、時計回りの方向に傾斜させた状態で上下の横筋4、4に斜交固着してあり、また、図7に示す他方の型枠筋本体1Bの場合は、上記とは反対の方向に左右の縦筋5、5を傾斜させた状態で上下の横筋4、4に斜交固着してあり、この点で上記第1の実施の形態の各縦筋5の配設方向と相違しており、上記以外の他の構成は第1の実施の形態と全く同一であるから、同一部分には同一符号を付してある。
この実施の形態の使用状態は図8に示す通りであって、図3に示した第1の実施の形態の使用状態と殆ど変わりはないが、上記した各縦筋5の下方の屈曲部5aの方向の相違により、下方の各嵌入部2に対する主鉄筋6の嵌入方向が第1の実施の形態の場合と逆方向になる点を除いては、その他の使用状態及び作用、効果も第1の実施の形態と同一であるから、それらの説明は省略する。
【0027】
なお、上記の各実施の形態において、対向配置した各型枠筋本体1A、1Bに設けた各主鉄筋の嵌入部2〜2は、それぞれの位置に対応して同じ位置に配設されている。
【0028】
以上、本発明の実施の形態のいくつかについて説明したが、本発明は、上記の実施の形態に限定されるものではなく、本発明の目的を達成でき且つ本発明の要旨を逸脱しない範囲内で種々の設計変更が可能である。
【0029】
【発明の効果】
本発明に係る法枠の型枠形成用の側枠付き型枠筋は、前記のように構成され、上記のようにして使用されるものであるから、主鉄筋を無結束状で容易、確実に配筋でき、法枠の型枠の各形成部材を多くの個所で結束していた従来技術に比べて、著しく能率的に法枠の型枠を形成できる多大な効果を奏すると共に、型枠筋本体を構成するための縦筋の使用本数も著しく少ないため、安価にこの種の型枠筋を提供できる利点を有するものである。
また、本発明では、型枠筋の両側枠を予め工場で取付けてあるので、現場で側枠を取付ける手間を省けると共に、型枠筋に側枠を枢着してあるので、折畳んでその嵩を縮小でき、保管や現場への運搬を容易に行ない得る利点がある。

The configuration is remarkably simple, and there is a great advantage that it can be manufactured inexpensively and easily, and the bent portions 5a and 5a of the opposing fitting portions 2 and 2 in the oppositely placed both formwork main bodies 1A and 1B are as follows. Since each main reinforcement 6 in each insertion part 2 is each provided in the opposite side, there exists an advantage hold | maintained reliably from both right and left sides.
[0023]
4 and 5 schematically show the second embodiment of the present invention. The difference from the first embodiment is that two vertical stripes 5 and 5 on both sides are provided. The vertical stripes are doubled to form a so-called double type, and the other parts are the same as those in the first embodiment, so that the same parts are omitted from the reference numerals. In addition, descriptions of the same use state and the same actions and effects are omitted.
[0024]
According to the second embodiment, since the number of main reinforcing bars 6 used can be doubled, there is an advantage that the strength of the normal frame can be increased. By inserting the short main reinforcing bars 6 to 6 using the increased insertion portions 2 of the longitudinal bars, there is also an advantage that the formwork bars with the side frames can be reliably transferred.
[0025]
6 and 7 schematically show the third embodiment of the present invention. The difference from the first embodiment is that each of the two formwork main bodies 1A and 1B. A point where the bent part 5a below the vertical line 5 is provided in the direction opposite to the bent part 5a of the first embodiment, and one vertical line 5, 5 is provided on each side of the upper and lower horizontal lines 4, 4. At the time of arrangement, only the points arranged obliquely to the transverse stripes 4 and 4 in the illustrated manner are shown.
[0026]
That is, the arrangement direction of the vertical bars 5 will be described. In the case of one formwork main body 1A shown in FIG. 6, the left vertical bars 5 are inclined in the counterclockwise direction toward the same figure. In the state, it is obliquely fixed to the upper and lower horizontal stripes 4 and 4, and the right vertical stripe 5 is obliquely fixed to the upper and lower horizontal stripes 4 and 4 while being inclined in the clockwise direction. In the case of the other formwork main body 1B shown in FIG. 1, the left and right vertical bars 5, 5 are inclined in the opposite direction to the above, and are obliquely fixed to the upper and lower horizontal bars 4, 4. This is different from the arrangement direction of the vertical bars 5 in the first embodiment, and other configurations are the same as those in the first embodiment. It is.
The use state of this embodiment is as shown in FIG. 8 and is almost the same as the use state of the first embodiment shown in FIG. 3, but the bent portion 5a below each longitudinal muscle 5 described above. The other use states, functions, and effects are also the same except that the insertion direction of the main reinforcing bar 6 with respect to each lower insertion portion 2 is opposite to that in the first embodiment due to the difference in direction. Since these are the same as those of the embodiment, their description is omitted.
[0027]
In each of the above-described embodiments, the main reinforcing bar insertion portions 2 and 2 provided in the opposing formwork main bodies 1A and 1B are arranged at the same position corresponding to the respective positions. .
[0028]
While some of the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can achieve the object of the present invention and does not depart from the gist of the present invention. Various design changes are possible.
[0029]
【The invention's effect】
The formwork with side frames for forming the formwork of the legal frame according to the present invention is configured as described above and is used as described above. Compared to the prior art in which each forming member of the form frame is bundled at many places, the form frame of the form frame can be formed remarkably efficiently, and the form frame is produced. Since the number of longitudinal bars used for constituting the muscle main body is remarkably small, there is an advantage that this type of formwork can be provided at low cost.
Further, in the present invention, both side frames of the formwork are pre-installed at the factory, so that it is possible to save the trouble of attaching the side frame at the site and the side frame is pivotally attached to the formwork, so that it can be folded. There is an advantage that the bulk can be reduced and storage and transportation to the site can be easily performed.
