特開２０１２−００７３２６号公報JP 2012-007326 A

特許文献１に記載された従来の型枠浮かし支持具の構成では、型枠支持用アームとは別に、合成樹脂製のコーンと、このコーンの下端から垂直下方に突出する螺軸、及びこの螺軸を螺合連結させるために前記型枠支持用アームに設けられた上下方向のネジ孔が必要であり、実施コストが高くつくものであった。 In the configuration of the conventional mold floating support described in Patent Document 1, a synthetic resin cone, a screw shaft that protrudes vertically downward from the lower end of the cone, and the screw are separated from the mold support arm. In order to threadably connect the shafts, vertical screw holes provided in the formwork support arm are necessary, which is expensive to implement.

本発明は、上記のような従来の問題点を解消することのできる型枠浮かし支持具を提案するものであって、第一の本発明に係る型枠浮かし支持具は、後述する実施例との関係を理解し易くするために、当該実施例の説明において使用した参照符号を括弧付きで付して示すと、鉄筋(2)への取付け部(6)と、この取付け部(6)から水平に連設された型枠支持用アーム(7)と、この型枠支持用アーム(7)に設けられた型枠支持部(9)とから成る型枠浮かし支持具(1)であって、前記型枠支持用アーム(7)は、前記取付け部(6)から板面が上下垂直向きとなるように連設された帯状板(8)から成り、前記型枠支持部(9)は、前記帯状板(8)の上側辺を片側へ斜めに折曲させた折曲側辺部(8a)で構成され、支持する型枠(5)の下端面が、前記帯状板(8)の折曲側辺部(8a)の端面両出隅角の上側になる出隅角(8b)に線接触の状態で支持される構成になっている。 The present invention proposes a form-floating support that can solve the conventional problems as described above, and the form-floating support according to the first aspect of the present invention is the following embodiment. In order to facilitate understanding of the relationship, when the reference numerals used in the description of the embodiment are shown in parentheses, the attachment part (6) to the reinforcing bar (2) and the attachment part (6) A formwork floating support (1) comprising a formwork support arm (7) provided horizontally and a formwork support part (9) provided on the formwork support arm (7). The mold support arm (7) is composed of a strip-shaped plate (8) arranged so that the plate surface is vertically oriented from the mounting portion (6), and the mold support portion (9) The upper side of the belt-like plate (8) is formed of a bent side portion (8a) that is bent obliquely to one side, and the lower end surface of the supporting mold (5) is the side of the belt-like plate (8). Both corners of the end face of the bent side (8a) Has become external corner angle consisting of the upper (8b) configured to be supported in a state of line contact.

又、第二の本発明に係る型枠浮かし支持具は、鉄筋(2)への取付け部(6)と、この取付け部(6)から水平に連設された型枠支持用アーム(7)と、この型枠支持用アーム(7)に設けられた型枠支持部(9)とから成る型枠浮かし支持具(1)であって、前記型枠支持用アーム(7)は、前記取付け部(6)から板面が上下垂直向きとなるように連設された帯状板(8)から成り、前記型枠支持部(9)は、前記帯状板(8)の上側辺の、この帯状板(8)の長さ方向適当間隔おきに並ぶ山部(12)が形成された凹凸上側辺部(13)で構成され、支持する型枠(5)の下端面が、前記帯状板(8)の凹凸上側辺部(13)の複数の山部(12)の尖端(12a)によって支持される構成になっている。 Further, the formwork floating support according to the second aspect of the present invention includes an attachment part (6) to the reinforcing bar (2), and a formwork support arm (7) connected horizontally from the attachment part (6). And a formwork floating support (1) comprising a formwork support part (9) provided on the formwork support arm (7), wherein the formwork support arm (7) It consists of a strip-like plate (8) connected so that the plate surface is vertically vertical from the portion (6), and the formwork support portion (9) is the strip-like shape on the upper side of the strip-like plate (8). The plate (8) is composed of an uneven upper side part (13) formed with ridges (12) arranged at appropriate intervals in the length direction, and the lower end surface of the supporting mold (5) is the strip plate (8 ) Is supported by the tips (12a) of the plurality of crests (12) of the uneven upper side (13).

上記本発明の構成によれば、浮かし型枠を支持する型枠支持部は、取付け部から水平に連設された型枠支持用アームを構成する帯状板の上側辺そのもので構成され、従来のように、合成樹脂製のコーン、このコーンの下端から垂直下方に突出する螺軸、及びこの螺軸を螺合連結させるために前記帯状板に設けられた上下方向のネジ孔などが一切不要であり、非常に安価に実施することが出来る。しかも、板面が上下方向の帯状板の上側辺は、板厚が薄いものであるとしても、平坦な端面が存在するので、この平坦な端面で浮かし型枠を支持させたのでは、仕上がった床版の表面に、前記帯状板の平坦な端面が帯状に露出することになり、非常に目立ちやすいし、この帯状露出面とコンクリート面との境界からコンクリートが剥がれ易いが、本発明の構成では、極細い線か又は点状に帯状板が露出することになるので、非常に目立ち難いし、コンクリートの剥がれ易さも改善される。 According to the configuration of the present invention, the formwork support part that supports the floating formwork is configured by the upper side itself of the belt-like plate that constitutes the formwork support arm horizontally provided from the attachment part. Thus, there is no need for a synthetic resin cone, a screw shaft that protrudes vertically downward from the lower end of the cone, and a vertical screw hole provided in the belt-like plate for screwing and connecting the screw shaft. Yes, it can be implemented very cheaply. Moreover, even if the upper side of the strip-shaped plate whose plate surface is in the vertical direction is thin, there is a flat end surface. Therefore, when the floating formwork is supported by this flat end surface, the finished shape is finished. On the surface of the floor slab, the flat end surface of the strip plate will be exposed in a strip shape, and it is very conspicuous, and the concrete is easily peeled off from the boundary between the strip exposed surface and the concrete surface. Since the strip-like plate is exposed in the form of very fine lines or dots, it is very inconspicuous and the ease of peeling of the concrete is improved.

上記本発明を実施する場合、具体的には、前記型枠支持部(9)は、前記帯状板(8)の全長にわたって形成するのが望ましい。この構成によれば、型枠支持用アーム（帯状板）の全長域の何れの箇所でも浮かし型枠を支持させることが出来、従来のように、浮かし型枠の支持位置に応じて型枠支持部の位置を、縦筋に対する遠近方向に調整する必要も無くなり、作業性が向上する。又、第一発明の実施に際しては、使用する帯状板として板厚の薄い板材を使用して、軽量化とコストダウンを図っても、型枠支持用アームそのものの曲げ強度を高めることが出来る。 When carrying out the present invention, specifically, it is desirable that the formwork support portion (9) is formed over the entire length of the strip plate (8). According to this configuration, the floating formwork can be supported at any part of the entire length of the formwork support arm (band-like plate), and the formwork support is supported according to the support position of the floating formwork as in the past. It is not necessary to adjust the position of the portion in the perspective direction with respect to the vertical stripe, and workability is improved. Further, when the first invention is carried out, the bending strength of the mold supporting arm itself can be increased even if a thin plate material is used as the belt-like plate to be used to reduce the weight and the cost.

又、前記取付け部(6)は、上下反転させることにより、上下方向の縦筋(2)に対し左右何れ側からも嵌合可能な嵌合部材(10)と、この嵌合部材(10)内に嵌合した前記縦筋(2)を押圧固定する締結用ボルト(11)とから構成し、前記型枠支持用アーム(7)は、前記嵌合部材(10)から、板面が上下垂直向きとなるように一体に連設された帯状板(8)から構成し、前記型枠支持部(9)は、前記帯状板(8)の上下両側辺に設けることが出来る。この構成によれば、この型枠浮かし支持具を取り付けようとする縦筋の周囲の状況によって、当該縦筋に型枠浮かし支持具を左右何れ側からでも取り付けることが出来る。 Further, the mounting portion (6) can be fitted to the vertical stripe (2) in the vertical direction from the left and right sides by turning upside down, and the fitting member (10). It is composed of fastening bolts (11) that press and fix the longitudinal bars (2) fitted inside, and the formwork support arm (7) has a plate surface up and down from the fitting member (10). It is composed of a strip-like plate (8) integrally connected so as to be vertically oriented, and the mold support (9) can be provided on both upper and lower sides of the strip-like plate (8). According to this configuration, depending on the situation around the vertical stripe to which the formwork floating support is to be attached, the formwork floating support can be attached to the vertical line from either the left or right side.

上記のように、前記取付け部(6)を、上下方向の縦筋(2)に対し横から嵌合可能な嵌合部材(10)と、この嵌合部材(10)内に嵌合した前記縦筋(2)を押圧固定する締結用ボルト(11)とから構成し、前記型枠支持用アーム(7)は、前記嵌合部材(10)から、板面が上下垂直向きとなるように一体に連設された帯状板(8)から構成する場合は、前記嵌合部材(10)の、前記縦筋(2)に外嵌当接する、平面形状がＶ字形に凹入する縦筋受け部(10a)を、前記型枠支持用アーム(7)を構成する帯状板(8)の上下巾よりも上下方向高さを大きくし、前記嵌合部材(10)の、前記帯状板(8)と前記縦筋受け部(10a)との間の上側縁(10f)は、前記帯状板(8)の型枠支持部(9)における型枠支持高さと同一高さにするのが望ましい。この構成によれば、前記嵌合部材の前記縦筋に外嵌当接する縦筋受け部の高さが、前記型枠支持用アームを構成する帯状板の上下巾と等しい構成と比較して、前記型枠支持用アームを構成する帯状板の上下巾は必要最小限に抑えながら、前記嵌合部材の前記縦筋に当接する縦筋受け部には十分な高さを持たせて、縦筋に対する取付け状態での安定性と強度を高めることが出来る。しかも、前記嵌合部材の、縦筋に外嵌当接する縦筋受け部に隣接する部分の上側辺を参照して、縦筋に対する取付け高さを、支持する型枠の下端高さに対応した高さに容易に合わせることが出来る。 As described above, the attachment portion (6), the fitting member (10) that can be fitted from the side to the vertical stripe (2) in the vertical direction, and the fitting member (10) fitted in the fitting member (10) It is composed of fastening bolts (11) for pressing and fixing the vertical bars (2), and the formwork support arm (7) is arranged so that the plate surface is vertically oriented from the fitting member (10). In the case where the belt-shaped plate (8) is integrally connected, the vertical member receiving portion of the fitting member (10) that comes into contact with the vertical stripe (2) and that has a planar shape recessed into a V shape is provided. The height of the portion (10a) is made larger than the vertical width of the strip plate (8) constituting the mold support arm (7), and the strip plate (8) of the fitting member (10) ) And the vertical line receiving portion (10a), the upper edge (10f) is preferably the same height as the mold support height in the mold support (9) of the strip plate (8). According to this configuration, the height of the vertical bar receiving portion that externally contacts the vertical bar of the fitting member is compared with the configuration that is equal to the vertical width of the belt-like plate that forms the mold support arm, While maintaining the vertical width of the belt-like plate constituting the formwork support arm to the minimum necessary, the vertical bar receiving portion contacting the vertical bar of the fitting member has a sufficient height so that the vertical bar It is possible to increase the stability and strength in the mounted state. In addition, with reference to the upper side of the portion adjacent to the vertical bar receiving portion that is externally fitted to the vertical bar of the fitting member, the mounting height for the vertical bar corresponds to the lower end height of the supporting formwork. Can be easily adjusted to the height.

更に、前記型枠支持用アーム(7)の前記型枠支持部(9)となる箇所には、当該型枠支持部(9)における型枠支持高さよりも低い位置で上下方向に貫通する軸杆挿通孔(17)を設け、この軸杆挿通孔(17)に差し込み可能な軸杆(16)の上端部に合成樹脂製コーン(15)を着脱自在に螺嵌し、このコーン(15)の下端から突出する前記軸杆(16)を前記軸杆挿通孔(17)に差し込んだとき、前記コーン(15)の下端が、前記型枠支持部(9)で支持されるように構成することが出来る。この構成によれば、線状又は点状といえども、金属製の帯状板がコンクリート表面に露出することが許されず、必ず一定のコンクリート被り厚さを確保しなければならないような現場では、前記合成樹脂製コーンの下端から突出する前記軸杆を前記軸杆挿通孔に差し込んで、前記合成樹脂製のコーンで浮かし型枠を支持させるように使用することが出来る。この場合、前記合成樹脂製のコーンが型枠支持用アーム（帯状板）の上側辺で直接支持されるものであり、従来のように、前記コーンを支持する螺軸が型枠支持用アームとの間に存在する構成と比較して、コーンを安定良く且つ支持強度の高い状態で支持させることが出来る。 Further, a shaft penetrating in the vertical direction at a position lower than the mold support height in the mold support section (9) is provided at a position to be the mold support section (9) of the mold support arm (7).杆 Insertion hole (17) is provided, and a synthetic resin cone (15) is detachably screwed onto the upper end of the shaft 杆 (16) that can be inserted into this shaft 杆 insertion hole (17). When the shaft rod (16) protruding from the lower end of the shaft is inserted into the shaft rod insertion hole (17), the lower end of the cone (15) is supported by the formwork support portion (9). I can do it. According to this configuration, even if it is linear or dotted, the metal strip is not allowed to be exposed on the concrete surface, and in the field where a certain concrete covering thickness must be ensured, The shaft rod projecting from the lower end of the synthetic resin cone can be inserted into the shaft rod insertion hole, and can be used so as to be supported by the synthetic resin cone. In this case, the synthetic resin cone is directly supported on the upper side of the mold support arm (band plate), and the screw shaft supporting the cone is the mold support arm and Compared with the structure existing between the two, the cone can be supported in a stable and high strength state.

図１において、１は型枠浮かし支持具、２は、床版構築用のコンクリート打設空間３内から立上り壁構築用のコンクリート打設空間４内にわたって配設された上下方向の縦筋、５は、型枠浮かし支持具１によって支持された立上り壁構築用のコンクリート型枠５（以下、浮かし型枠と称する）である。 In FIG. 1, reference numeral 1 denotes a formwork floating support, and 2 denotes vertical vertical bars arranged from the concrete placement space 3 for floor slab construction to the concrete placement space 4 for rise wall construction, 5 Is a concrete formwork 5 for building a rising wall supported by the formwork floating support 1 (hereinafter referred to as a floating formwork).

以下、型枠浮かし支持具１の具体構造を、図２及び図３に基づいて説明すると、型枠浮かし支持具１は、１枚の鉄板からプレス加工によって構成されたもので、縦筋２への取付け部６と、この取付け部６から水平に連設された型枠支持用アーム７から構成されている。取付け部６は、上下反転させることにより、縦筋２に対し左右何れ側からも嵌合させることが出来る嵌合部材１０と、この嵌合部材１０内に嵌合した縦筋２を押圧固定する締結用ボルト１１とから構成されている。嵌合部材１０は、縦筋２に外嵌当接する、平面形状がＶ字形に凹入する縦筋受け部１０ａと、この縦筋受け部１０ａの一端から連設されて、当該縦筋受け部１０ａに対面する板部１０ｂとから成り、この板部１０ｂに、前記締結用ボルト１１が、縦筋受け部１０ａに対する遠近方向に螺合貫通する貫通ネジ孔１０ｃが設けられている。前記嵌合部材１０には、その全域にわたって外側に突曲する補強用リブ１０ｄが一体形成されている。型枠支持用アーム７は、嵌合部材１０の板部１０ｂの遊端から、板面が上下垂直向きとなるように、縦筋受け部１０ａから遠ざかる方向に一体に折曲連設された帯状板８から構成され、この帯状板８の上側辺が型枠支持部９となっている。 Hereinafter, the specific structure of the mold floating support 1 will be described with reference to FIGS. 2 and 3. The mold floating support 1 is formed by pressing from a single iron plate. And a formwork supporting arm 7 provided horizontally from the mounting portion 6. The attachment part 6 presses and fixes the fitting member 10 that can be fitted to the vertical bar 2 from either the left or right side by flipping up and down, and the vertical bar 2 fitted in the fitting member 10. It is comprised from the bolt 11 for fastening. The fitting member 10 is externally abutted on the vertical stripe 2 and has a vertical stripe receiving portion 10a whose planar shape is recessed in a V shape, and is connected to one end of the vertical stripe receiving portion 10a. The plate portion 10b is provided with a through screw hole 10c through which the fastening bolt 11 is threaded and penetrated in the perspective direction with respect to the longitudinal bar receiving portion 10a. The fitting member 10 is integrally formed with reinforcing ribs 10d that project outward over the entire area. The formwork support arm 7 is a belt-like shape that is integrally bent in a direction away from the vertical bar receiving portion 10a so that the plate surface is vertically vertical from the free end of the plate portion 10b of the fitting member 10. It is comprised from the board 8, and the upper side of this strip | belt-shaped board 8 becomes the formwork support part 9. FIG.

前記嵌合部材１０は、板部１０ｂの遊端から縦筋受け部１０ａまでの上下巾よりも、縦筋受け部１０ａの上下巾が大きくなった、締結用ボルト１１の軸心に対し上下対称形状のものであって、貫通ネジ孔１０ｃが、補強用リブ１０ｄ内に入り込むバーリング加工を伴っている関係で、補強用リブ１０ｄの上下両側の板巾の不足を補うために、板部１０ｂの上下両側辺には、貫通ネジ孔１０ｃの上下両側において円弧形突出部１０ｅが設けられている。型枠支持用アーム７を構成する帯状板８は、嵌合部材１０の縦筋受け部１０ａを除く部分の上下巾よりも更にその上下巾が狭くなったもので、その上側縁と、嵌合部材１０の縦筋受け部１０ａを除く部分の上側縁１０ｆとは同一高さで連続している。従って、型枠支持用アーム７を構成する帯状板８は、嵌合部材１０の上下巾の中心より上側に偏っていることになる。 The fitting member 10 is vertically symmetric with respect to the axis of the fastening bolt 11 in which the vertical width of the vertical bar receiving portion 10a is larger than the vertical width from the free end of the plate portion 10b to the vertical bar receiving portion 10a. In order to compensate for the shortage of the plate width on both the upper and lower sides of the reinforcing rib 10d, the through screw hole 10c is accompanied by a burring process that enters the reinforcing rib 10d. On both the upper and lower sides, arc-shaped protrusions 10e are provided on both upper and lower sides of the through screw hole 10c. The strip-shaped plate 8 constituting the formwork support arm 7 has a narrower vertical width than the vertical width of the portion of the fitting member 10 excluding the vertical bar receiving portion 10a. The upper edge 10f of the member 10 excluding the vertical line receiving portion 10a is continuous at the same height. Therefore, the belt-like plate 8 constituting the mold support arm 7 is biased upward from the center of the vertical width of the fitting member 10.

型枠支持部９は、帯状板８の上側辺をその全長域にわたって片側へ斜めに折曲した折曲上側辺８ａで構成され、図１Ｃに示すように、支持する浮かし型枠５の下端面が、前記折曲上側辺８ａの端面両出隅角の上側になる出隅角８ｂに線接触の状態で支持されるように構成している。図示の実施例では、帯状板８の下側辺も、その全長域にわたって前記折曲側辺部８ａと同一側へ斜めに折曲した折曲下側辺８ｃとなっている。 The formwork support portion 9 is composed of a bent upper side 8a formed by obliquely bending the upper side of the belt-like plate 8 to one side over its entire length region, and as shown in FIG. 1C, the lower end surface of the floating formwork 5 to be supported However, it is configured to be supported in a line contact state at the protruding corner angle 8b which is the upper side of both protruding corner angles of the bent upper side 8a. In the illustrated embodiment, the lower side of the belt-like plate 8 is also a bent lower side 8c that is bent obliquely to the same side as the bent side 8a over its entire length.

上記構成の型枠浮かし支持具１は、型枠支持用アーム７が縦筋２に対し浮かし型枠５が配置される側へ突出するように、取付け部６の嵌合部材１０を縦筋２に横から嵌合し、縦筋２に嵌合部材１０の縦筋受け部１０ａを外嵌させた状態で、締結用ボルト１１を捻じ込んで、この締結用ボルト１１の先端と嵌合部材１０の縦筋受け部１０ａとの間で縦筋２を挟み込むことにより、縦筋２の所定高さに取り付けられるものであるが、その縦筋２に対する型枠浮かし支持具１の取付け高さは、浮かし型枠５の下端高さで縦筋２に目印線を印しておき、嵌合部材１０の、縦筋受け部１０ａを除く部分の上側縁１０ｆを前記目印線に合わせることによって決めることが出来る。この後、浮かし型枠５を、型枠支持用アーム７の型枠支持部９となっている折曲上側辺８ａ上に載置支持させる。この結果、浮かし型枠５の下端面が、折曲上側辺８ａの端面両出隅角の上側になる出隅角８ｂに線接触の状態で支持される。尚、嵌合部材１０の縦筋受け部１０ａを除く部分の上側縁１０ｆと同一高さにあった帯状板８の上側辺は、片側への斜めの折曲によって若干低くなっているので、厳密には、嵌合部材１０の上側縁１０ｆと同一高さで縦筋２に印された目印線の高さは、浮かし型枠５の下端面が当接する折曲上側辺８ａの出隅角８ｂの高さより僅かに高くなるが、実用上は全く問題無い。 The mold floating support 1 having the above-described configuration is configured so that the fitting member 10 of the attachment portion 6 is connected to the vertical bar 2 so that the mold support arm 7 protrudes from the vertical bar 2 to the side where the floating frame 5 is disposed. The fastening bolt 11 is screwed in a state in which the fastening member 11 is fitted from the side and the longitudinal streak receiving portion 10 a of the fitting member 10 is externally fitted to the longitudinal streak 2, and the end of the fastening bolt 11 and the fitting member 10. The vertical streak 2 is sandwiched between the vertical streak receiving portion 10a and attached to a predetermined height of the vertical streak 2, but the mounting height of the formwork floating support 1 with respect to the vertical streak 2 is A mark line is marked on the vertical stripe 2 at the lower end height of the floating formwork 5, and the upper edge 10f of the fitting member 10 excluding the vertical stripe receiving portion 10a is aligned with the mark line. I can do it. Thereafter, the floating mold 5 is placed and supported on the bent upper side 8 a that is the mold support 9 of the mold support arm 7. As a result, the lower end surface of the floating formwork 5 is supported in a line contact state on the protruding corner angle 8b which is above the protruding corner angle of the end surface of the bent upper side 8a. Note that the upper side of the belt-like plate 8 that is at the same height as the upper edge 10f of the fitting member 10 excluding the vertical line receiving portion 10a is slightly lower due to the oblique bend to one side. The height of the mark line marked on the vertical streak 2 at the same height as the upper edge 10f of the fitting member 10 is such that the protruding corner angle 8b of the bent upper side 8a with which the lower end surface of the floating formwork 5 abuts. However, there is no problem in practical use.

床版構築用のコンクリート打設空間３及び立上り壁構築用のコンクリート打設空間４内に配筋してコンクリートを打設し、所定期間の養生後に浮かし型枠５を解体除去するのであるが、浮かし型枠５の下端面と同一レベルに表面が仕上げられる床版の表面には、浮かし型枠５の下端面相当位置に、型枠支持用アーム７の型枠支持部９における折曲上側辺８ａの出隅角８ｂが線状に露出することになるが、殆ど目立たない。 The concrete is placed in the concrete placement space 3 for constructing the floor slab and the concrete placement space 4 for constructing the rising wall, and the concrete is placed. After curing for a predetermined period, the floating form 5 is dismantled and removed. On the surface of the floor slab whose surface is finished at the same level as the lower end surface of the floating formwork 5, the upper side of the bent portion of the formwork support arm 7 at the position corresponding to the lower end face of the floating formwork 5. Although the protruding corner angle 8b of 8a is exposed in a line, it is hardly noticeable.

尚、縦筋２の周囲の状況によって、帯状板８の上側辺の型枠支持部９が下になる向きに嵌合部材１０を縦筋２に取り付けた場合であっても、上側になった帯状板８の折曲下側辺８ｃも、構造は、型枠支持部９となる折曲上側辺８ａと同一であるから、浮かし型枠５を型枠支持部９となる折曲上側辺８ａで支持する場合と全く変わりなく、帯状板８の折曲下側辺８ｃの上側になる出隅角８ｄ（図１Ｃ参照）によって浮かし型枠５を支持させることが出来るが、このような使用方法が想定される場合は、図３Ａに示すように、前記帯状板８の上下巾を嵌合部材１０の縦筋受け部１０ａを除く部分の上下巾と等しくし、嵌合部材１０の板部１０ｂをそのまま延長させて折曲することにより、型枠支持用アーム７を構成させることが望ましい。この構成では、帯状板８の折曲下側辺８ｃの出隅角８ｄと、嵌合部材１０の縦筋受け部１０ａを除く部分の下側縁１０ｇとが略同一高さで連続することになるので、型枠浮かし支持具１を上下反転させて、縦筋２に対し嵌合部材１０を反対側から嵌合させて使用した場合も、縦筋２に対する型枠浮かし支持具１の取付け高さの決定などを同じように行うことが出来る。 In addition, even when the fitting member 10 is attached to the vertical bar 2 so that the formwork support 9 on the upper side of the belt-like plate 8 faces downward depending on the situation around the vertical bar 2, it is on the upper side. The structure of the bent lower side 8c of the belt-like plate 8 is also the same as that of the bent upper side 8a that becomes the mold support 9, so that the floating mold 5 becomes the bent upper side 8 a that becomes the mold support 9. The floating form 5 can be supported by the protruding corner angle 8d (see FIG. 1C) which is the upper side of the bent lower side 8c of the belt-like plate 8. 3A, as shown in FIG. 3A, the vertical width of the strip-shaped plate 8 is made equal to the vertical width of the portion excluding the vertical bar receiving portion 10a of the fitting member 10, and the plate portion 10b of the fitting member 10 is used. It is desirable to form the arm 7 for supporting the formwork by extending and bending as it is. In this configuration, the protruding corner angle 8d of the bent lower side 8c of the belt-like plate 8 and the lower edge 10g of the fitting member 10 excluding the vertical bar receiving portion 10a are continuous at substantially the same height. Therefore, even when the mold floating support 1 is turned upside down and the fitting member 10 is fitted to the vertical bar 2 from the opposite side, the height of the mold floating support 1 attached to the vertical bar 2 is also high. You can make the same decision.

又、型枠支持部９を、帯状板８の側辺を片側へ斜めに折曲させて構成するのではなく、図３Ｂに示すように、板面全体が平坦な帯状板８の上側辺に、この帯状板８の長さ方向適当間隔おきに並ぶ山部１２が形成された凹凸上側辺部１３を構成して、型枠支持部９とすることも出来る。この場合は、支持される浮かし型枠５の下端面が、前記凹凸上側辺部１３の複数の山部１２の尖端１２ａによって支持されることになる。尚、この場合も、型枠支持部９となる凹凸上側辺部１３を、帯状板８の側辺の全長域にわたって構成することが出来るし、帯状板８の下側辺にも、前記凹凸上側辺部１３と同一の凹凸下側辺部１４を構成することが出来る。 Further, the formwork support portion 9 is not formed by bending the side of the belt-like plate 8 diagonally to one side, but as shown in FIG. 3B, the entire plate surface is placed on the upper side of the belt-like plate 8. Further, the uneven support upper side portion 13 in which the crest portions 12 arranged at appropriate intervals in the length direction of the belt-like plate 8 are formed can be used as the formwork support portion 9. In this case, the lower end surface of the floating formwork 5 to be supported is supported by the tips 12 a of the plurality of crest portions 12 of the uneven upper side portion 13. In this case as well, the uneven upper side 13 serving as the mold support 9 can be formed over the entire length of the side of the belt-like plate 8, The same concave / convex lower side portion 14 as the side portion 13 can be formed.

以上に示した型枠浮かし支持具１は、型枠支持用アーム７に対するコンクリートの被りを確保する必要のない場合に活用出来るものであるが、型枠支持用アーム７に対するコンクリートの被りを確保しなければならない場合にも活用出来るように、次のように構成することが出来る。即ち、図４〜図５に示すように、上端が下端より大径の裁頭円錐形の合成樹脂製のコーン１５と、所定長さの螺軸から成る軸杆１６と、型枠支持用アーム７に設けられた上下方向の軸杆差込み孔１７とが追加される。コーン１５は、その中心部に、上下方向に貫通する貫通ネジ孔１５ａを形成する金属製の円筒形インサート１５ｂが埋設されたもので、前記軸杆１６の上端螺軸部１６ａが貫通ネジ孔１５ａに下端側から着脱自在に螺嵌連結されている。このとき、コーン１５の下端から突出する軸杆１６の下端突出部１６ｂの長さを一定にするため、所定長さの軸杆１６の上端一定領域にのみネジ溝を加工して、このネジ溝が加工された一定長さの上端螺軸部１６ａだけを貫通ネジ孔１５ａ内に螺入出来るようにしても良いが、図示のように全長にわたってネジ溝が加工された螺軸を軸杆１６として使用するときは、貫通ネジ孔１５ａ内に螺嵌させる一定長さの上端螺軸部１６ａの下端位置に、それ以上の貫通ネジ孔１５ａ内への螺入を阻止するための、ネジ溝を一部分加圧変形させたカシメ部１６ｃを設けておくのが望ましい。 The above-described formwork support 1 can be used when it is not necessary to secure the concrete cover on the formwork support arm 7, but ensures the concrete cover on the formwork support arm 7. It can be configured as follows so that it can be used even when it is necessary. That is, as shown in FIGS. 4 to 5, a truncated cone-shaped synthetic resin cone 15 whose upper end is larger in diameter than the lower end, a shaft rod 16 composed of a screw shaft of a predetermined length, and a mold support arm 7 and an axial shaft insertion hole 17 in the vertical direction is added. The cone 15 is formed by embedding a metal cylindrical insert 15b forming a through screw hole 15a penetrating in the vertical direction at the center, and the upper end screw shaft portion 16a of the shaft rod 16 is formed through the through screw hole 15a. And is detachably screwed from the lower end side. At this time, in order to make the length of the lower end protruding portion 16b of the shaft rod 16 protruding from the lower end of the cone 15 a thread groove is processed only in the upper end constant region of the shaft rod 16 having a predetermined length, and this thread groove Only the upper end screw shaft portion 16a having a certain length that has been machined may be screwed into the through screw hole 15a. However, as shown in FIG. When used, a part of a screw groove for preventing further screwing into the through screw hole 15a is provided at the lower end position of the upper end screw shaft portion 16a having a predetermined length to be screwed into the through screw hole 15a. It is desirable to provide a crimped portion 16c that is deformed under pressure.

軸杆１６のコーン１５の下端から突出する下端突出部１６ｂは、型枠支持用アーム７の側部に上下方向に貫通するように設けられた前記軸杆差し込み孔１７に上から差し込まれる。軸杆差し込み孔１７は、型枠支持用アーム７を構成する帯状板８に、その長さ方向に沿って設けられた上下２本の切込みの間の板部を、折曲上下両側辺８ａ，８ｃの折曲している側に突曲させた、帯状板８の上下巾の中心に位置する突曲板部１７ａの内側で構成されている。前記軸杆１６の下端突出部１６ｂは、帯状板８の上下巾とほぼ等しい長さになっており、この軸杆１６の下端突出部１６ｂを軸杆差し込み孔１７に上から下向きに差し込んで、コーン１５の下端を型枠支持用アーム７（帯状板８）の折曲上側辺８ａ又は折曲下側辺８ｃに支持させたとき、当該軸杆１６の下端突出部１６ｂは、帯状板８の折曲上下両側辺８ａ，８ｃの出隅角８ｂ，８ｄに隣接するように構成している。 A lower end protruding portion 16 b protruding from the lower end of the cone 15 of the shaft rod 16 is inserted from above into the shaft rod insertion hole 17 provided so as to penetrate the side portion of the formwork supporting arm 7 in the vertical direction. The shaft rod insertion hole 17 is formed by bending the plate portion between the upper and lower two cuts provided along the length direction on the belt-like plate 8 constituting the mold support arm 7, and bending the upper and lower sides 8 a, It is comprised inside the bent plate part 17a located in the center of the up-and-down width | variety of the strip | belt-shaped board 8 bent to the bending side of 8c. The lower end protruding portion 16b of the shaft rod 16 has a length substantially equal to the vertical width of the belt-like plate 8, and the lower end protruding portion 16b of the shaft rod 16 is inserted into the shaft rod insertion hole 17 downward from above. When the lower end of the cone 15 is supported by the bent upper side 8 a or the bent lower side 8 c of the mold support arm 7 (band-shaped plate 8), the lower end protruding portion 16 b of the shaft rod 16 is The bent upper and lower sides 8a and 8c are configured to be adjacent to the protruding corner angles 8b and 8d.

尚、この実施例は、図３Ａ又は図３Ｂに示す実施例の型枠支持用アーム７と組み合わせることも出来る。又、軸杆差し込み孔１７としては、帯状板８の側面に溶接などにより固着した筒状体の上下方向の中央貫通孔や、帯状板８の側面に溶接などにより固着した長尺ナットの上下方向の中央貫通ネジ孔で構成することも可能である。長尺ナットを利用するときは、コーン１５の下端から突出する軸杆１６の下端突出部１６ｂが螺軸である場合に、コーン１５の取付けをネジ嵌合により強固に行える。 This embodiment can also be combined with the mold support arm 7 of the embodiment shown in FIG. 3A or 3B. As the shaft insertion hole 17, the central through hole in the vertical direction of the cylindrical body fixed to the side surface of the strip plate 8 by welding or the vertical direction of the long nut fixed to the side surface of the strip plate 8 by welding or the like. It is also possible to configure with a central through screw hole. When using a long nut, when the lower end protrusion 16b of the shaft rod 16 protruding from the lower end of the cone 15 is a screw shaft, the cone 15 can be firmly attached by screw fitting.

上記のコーン１５を使用する場合、型枠支持用アーム７の軸杆差し込み孔１７に、コーン１５の下端から突出する軸杆１６の下端突出部１６ｂを上から下向きに差し込んで、コーン１５の下端を、型枠支持用アーム７（帯状板８）の上側縁（折曲上下両側辺８ａ，８ｃの出隅角８ｂ，８ｄの内、上側になる出隅角）に載置支持させた状態で使用される。この場合、縦筋２に対する型枠浮かし支持具１の取付け高さは、浮かし型枠５の下端高さからコーン１５の高さ分を差し引いた高さで、縦筋２に目印線を印しておき、嵌合部材１０の、縦筋受け部１０ａを除く部分の上下両側縁１０ｆ，１０ｇの内、上側になる側縁を前記目印線に合わせることによって決めることが出来る。又、縦筋２に型枠浮かし支持具１を取り付けるとき、締結用ボルト１１を完全に締め付ける前に、縦筋２に対する型枠支持用アーム９の向きを調整して、浮かし型枠５の真下位置にコーン１５を位置させる。 When the cone 15 is used, the lower end projecting portion 16b of the shaft rod 16 projecting from the lower end of the cone 15 is inserted into the shaft rod insertion hole 17 of the mold support arm 7 downward from the upper side, and the lower end of the cone 15 is inserted. Is mounted and supported on the upper edge of the mold support arm 7 (band plate 8) (the projected corner angle on the upper side of the bent corner angles 8b and 8d of the bent upper and lower sides 8a and 8c). used. In this case, the mounting height of the formwork floating support 1 with respect to the vertical streak 2 is a height obtained by subtracting the height of the cone 15 from the lower end height of the floating formwork 5, and a mark line is marked on the vertical streak 2. It can be determined by aligning the upper side edge of the upper and lower side edges 10f, 10g of the fitting member 10 excluding the vertical line receiving portion 10a with the mark line. In addition, when the formwork floating support 1 is attached to the vertical bars 2, the direction of the formwork support arms 9 with respect to the vertical bars 2 is adjusted before the fastening bolts 11 are completely tightened, so that they are directly below the floating formwork 5. Place cone 15 in position.

上記のコーン１５を併用するときは、床版構築用のコンクリート打設空間３及び立上り壁構築用のコンクリート打設空間４内に配筋してコンクリートを打設し、所定期間の養生後に浮かし型枠５を解体除去することによって構築される床版の表面には、浮かし型枠５の下端面相当位置にコーン１５の上端が露出しているので、このコーン１５を、軸杆１６の上端螺軸部１６ａに対するネジ戻し方向に回転操作して軸杆１６から除去すれば、床版の表面に、コーン１５の除去跡である裁頭円錐形の、底面から軸杆１６の上端螺軸部１６ａが突出している凹部が残ることになる。この凹部内にモルタルを充填して塞ぐことにより、床版の表面の仕上げが完了する。このようにして構築した床版には、金属板から成る型枠支持用アーム７（帯状板８）に対して、コーン１５の高さ分だけのコンクリートの被り厚さが確保される。 When the above cone 15 is used in combination, the concrete is placed in the concrete placement space 3 for floor slab construction and the concrete placement space 4 for rise wall construction, and the concrete is floated after curing for a predetermined period. Since the upper end of the cone 15 is exposed at a position corresponding to the lower end surface of the floating form 5 on the surface of the floor slab constructed by dismantling and removing the frame 5, the cone 15 is connected to the upper end screw of the shaft rod 16. If the shaft 16a is rotated in the screw return direction and removed from the shaft ridge 16, it is formed on the surface of the floor slab in the shape of a truncated cone, which is the removal mark of the cone 15, from the bottom surface to the upper screw portion 16a of the shaft ridge 16 The recessed part which protrudes will remain. Finishing the surface of the floor slab is completed by filling the recess with mortar. In the floor slab constructed in this way, a concrete covering thickness corresponding to the height of the cone 15 is secured with respect to the mold supporting arm 7 (band plate 8) made of a metal plate.

図示省略しているが、型枠支持用アーム７には、軸杆差し込み孔１７を帯状板８の長さ方向適当間隔おきに複数設けて、使用状態でのコーン１５と縦筋２との間の間隔を複数段に変更出来るように構成することも出来る。 Although not shown, the mold support arm 7 is provided with a plurality of shaft hole insertion holes 17 at appropriate intervals in the length direction of the belt-like plate 8, and between the cone 15 and the longitudinal bars 2 in use. It is also possible to configure so that the interval of the number can be changed to a plurality of stages.
