Description

本発明は、鉄筋コンクリート建物の外壁を成形する仮枠において、生コンクリートを打ち込んだ後に、室内側から、外壁の外側の仮枠をコンクリートから剥離するための工法と、鉄筋コンクリート仮枠構造、及び、構築した鉄筋コンクリート仮枠を直上階に移設するスライド工法、さらに、これに関連するコンクリート表面の気泡痕（空気あばた）を除去するための工法に関する。 The present invention relates to a temporary frame for forming the outer wall of a reinforced concrete building, a method for peeling the temporary frame outside the outer wall from the concrete from the indoor side after driving the ready-mixed concrete, a reinforced concrete temporary frame structure, and construction The present invention relates to a slide method for transferring a reinforced concrete temporary frame to a directly upper floor, and a method for removing bubble marks (air blow) on the concrete surface related thereto.

生コンクリートには、通常、３〜６％の空気が含まれているため、コンクリート仮枠に生コンクリートを打設して、そのまま硬化させた場合には、コンクリートの表面に無数の気泡痕（空気あばた）が残る。その為、従来においては、仮枠に生コンクリートを打ち込んだ後に、生コンクリートの締め固めを行っている。 Since ready-mixed concrete usually contains 3-6% air, when ready-mixed concrete is placed on a concrete temporary frame and cured as it is, countless bubble marks (air Abata) remains. Therefore, conventionally, the ready-mixed concrete is compacted after the ready-mixed concrete is driven into the temporary frame.

その際、壁仮枠のコンクリート表面の生コンクリートを締め固めるためには仮枠振動機を利用している。仮枠振動機はせき板を介して振動を生コンクリートに伝えるもので、振動が作用する範囲は表面部分に限られる。 At that time, a temporary frame vibrator is used to compact the ready-mixed concrete on the concrete surface of the wall temporary frame. The temporary frame vibrator transmits vibrations to the ready-mixed concrete through the slats, and the range in which the vibration acts is limited to the surface portion.

しかしながら、木製の仮枠に比べてプラスチック製（特許文献１参照）の鉄筋コンクリート仮枠の場合には、仮枠振動機を使用した場合でも、コンクリートの表面に無数の気泡痕（空気あばた）が残る現象が著しかった。 However, in the case of a reinforced concrete temporary frame made of plastic (see Patent Document 1) compared to a wooden temporary frame, even when a temporary frame vibrator is used, countless bubble marks (air blows) remain on the concrete surface. The phenomenon was remarkable.

その為、従来から、表面に無数の気泡痕（空気あばた）を残さないようにするためには、前田工繊株式会社の発売する、透水シートと排水ネットを積層した二重構造の仮枠用脱水クロス、商品名ＲＣクロス等を仮枠に貼り付けるといった方法があった。しかしながら、このようなＲＣクロスを使用する場合は、ＲＣクロスを施工する手間や費用がかさむといった問題点があった。 For that reason, in order to keep countless bubble marks (air blows) on the surface, it has been used for a temporary frame with a double-layer structure of water-permeable sheets and drainage nets that Maeda Kosen Co., Ltd. sells. There was a method of pasting a dehydrating cloth, a brand name RC cloth or the like on a temporary frame. However, when such an RC cloth is used, there is a problem that labor and cost for constructing the RC cloth are increased.

さらに、生コンクリートを仮枠に打設した後、コンクリート仮枠の内面に沿って櫛歯（特許文献２参照）を挿入して生コンクリートの表面側の気泡を除去して来た。 Furthermore, after placing ready-mixed concrete on a temporary frame, comb teeth (see Patent Document 2) are inserted along the inner surface of the concrete temporary frame to remove bubbles on the surface side of the ready-mixed concrete.

また、建物外壁に用いる鉄筋コンクリート仮枠を直上階に移設するためのスライド工法に関しては、従来より、鉄筋コンクリート建物の外壁を構築するために配置する複数枚のせき板を、横端太材に金物を取付けて固定し、外壁の外側の複数枚の堰板を、外壁の大きさと一体となるように構成し、仮枠用締付け金物（特許文献３参照）とセパレーターとの螺合を解く事により、外壁の外側の仮枠をコンクリート壁から剥離し、直上階に移設していた。 In addition, regarding the slide method for moving the reinforced concrete temporary frame used for the outer wall of the building to the upper floor, conventionally, a plurality of slats that are arranged to construct the outer wall of the reinforced concrete building are used, and hardware is applied to the side end thick wood. By attaching and fixing, a plurality of weir plates outside the outer wall are configured to be integrated with the size of the outer wall, and by unscrewing the temporary frame fastening hardware (see Patent Document 3) and the separator, The temporary frame outside the outer wall was peeled off from the concrete wall and relocated to the upper floor.

前記、プラスチック製の鉄筋コンクリート仮枠は、複数の補強リブが所定の間隔をもって平行に取付けられた平面長方形の枡形状で構成され、隣合うプラスチック仮枠を互いに固定する場合には、プラスチック仮枠の全周のフランジ面に、所定の間隔をもって開けられた孔に連結金具を挿入して固定していた。
特開平７‐２４７６７８ The plastic reinforced concrete temporary frame is composed of a planar rectangular bowl shape in which a plurality of reinforcing ribs are attached in parallel at a predetermined interval. When the adjacent plastic temporary frames are fixed to each other, A connecting metal fitting is inserted and fixed in a hole opened at a predetermined interval on the flange surface of the entire circumference.

更に、建物外壁に用いる鉄筋コンクリート仮枠を直上階に移設するためのスライド工法に関しては、建物の外側から作業員が仮枠用締付け金物のボルトを回転させて、仮枠用締付け金物とセパレーターの螺合を解く事が出来るように構成されている。
特開平６‐９３７２３ Furthermore, regarding the slide method for moving the reinforced concrete temporary frame used for the building outer wall to the directly upper floor, the worker rotates the bolt of the temporary frame fastening hardware from the outside of the building to screw the temporary frame fastening hardware and the separator. It is structured to be able to solve the match.

なお、別のコンクリートユニット仮枠スライド工法においては、コンパネ等のせき板に骨格となるリブ材を固定したコンクリート仮枠を連設し、板状セパレータとコンクリート仮枠締付金具によって上下の横バタ材を締結し、該、横バタ材を包囲するように横バタ材ホールド金具を取付け、コンクリート打設後においてコンクリート仮枠締付金具を全て解除することにより、前記、横バタ材が、ホールド金具に保存され、その状態でコンクリートユニット仮枠せき板に絡む板状セパレータの不要部分をコンクリート面からはみださないように捩切り除去することで脱型をし、一体化に構築されたコンクリートユニット仮枠を一括して直上階に移設させている。
特開２００８‐１１５５９１ In another concrete unit temporary frame slide method, a concrete temporary frame in which a rib material serving as a skeleton is fixed to a panel such as a control panel is connected in series, and a horizontal separator is formed by a plate separator and a concrete temporary frame fastening bracket. The horizontal butter material holding metal fitting is attached so as to surround the horizontal rubber material, and the concrete temporary frame fastening metal fitting is completely released after placing the concrete. In this state, the concrete unit is constructed by unmolding it by removing the unnecessary parts of the plate-like separators that are entangled with the temporary siding of the concrete unit so as not to protrude from the concrete surface. Unit temporary frames have been relocated to the upper floor.

しかしながら、木製仮枠に比べて、プラスチック製の鉄筋コンクリート仮枠の場合には、コンクリートの表面に無数の気泡痕（空気あばた）が残る現象が著しく、耐久性と美観に対する問題があった。 However, compared with wooden temporary frames, plastic reinforced concrete temporary frames have a remarkable phenomenon that countless bubble marks (air blows) remain on the surface of the concrete, resulting in problems with durability and aesthetics.

更に、前記、建物外壁に用いる鉄筋コンクリート仮枠を直上階に移設するための仮枠用締付け金物を用いたスライド工法においては、建物外壁に用いる鉄筋コンクリート仮枠をコンクリート壁と剥離するためには、作業員が、建物の外側で仮枠用締付け金物とセパレーターとの螺合を解く事が必要であり、その為、隣地の建物が境界線いっぱいまで建築されている場合には、新しく、これから建築する鉄筋コンクリート建物と、従来から、隣地に建っている建物との間に作業員が作業するための足場を構築しなくてはならず、都市部の建物が密集した、地価の高い土地や、建ぺい率が低い土地に住宅を建築する際には、隣地との間に足場を設置するための隣地離れ（約５０ｃｍ以上必要）を設けて、そのために室内の空間を狭くして鉄筋コンクリート建物を建築しなければならず、土地の有効活用と云う観点から問題を抱えていた。 Further, in the slide method using the temporary frame fastening hardware for moving the reinforced concrete temporary frame used for the building outer wall to the upper floor, in order to peel the reinforced concrete temporary frame used for the building outer wall from the concrete wall, work It is necessary for the worker to unscrew the temporary frame fastening hardware and the separator outside the building. Therefore, if the neighboring building is built to the full boundary, it will be built newly. A scaffold for workers to work must be built between the reinforced concrete building and the building on the adjacent land, which has a high land price and a building coverage ratio where urban buildings are densely packed. When building a house on a low land, provide a separation (necessary about 50 cm or more) to install a scaffold between the adjacent land, narrow the indoor space for that purpose, Must be building the REIT building, we had problems from the perspective of the effective use of land.

本発明は、このような従来の問題点に鑑み、外壁の構築後に外壁仮枠を壁から剥離する場合、外壁の外側から一切手を加えることなく外壁仮枠を壁から剥離する事を可能とすると共に、外壁の表面に気泡痕（空気あばた）を残さない、プラスチック製の鉄筋コンクリート仮枠を提供する事を目的とする。 In view of such conventional problems, the present invention makes it possible to peel the outer wall temporary frame from the wall without adding any hand from the outside of the outer wall when peeling the outer wall temporary frame from the wall after the construction of the outer wall. At the same time, an object of the present invention is to provide a plastic reinforced concrete temporary frame that does not leave bubble marks (air blow) on the surface of the outer wall.

さらに、仮枠に、押出成形した樹脂仮枠を用いるため、室内の高さを決める際に、樹脂仮枠を切断する位置により、仮枠の高さを自由に設定する事が容易に可能となり、お客様の要望により室内天井高を高くする事が容易に可能となる。 Furthermore, since an extruded resin temporary frame is used as the temporary frame, it is possible to easily set the height of the temporary frame depending on the position at which the resin temporary frame is cut when determining the height in the room. It is possible to easily increase the height of the indoor ceiling as requested by the customer.

Thus, the square pipe fixing member 44 and the fixing member 51 are fixed.

さらに、図５ｂの角パイプ挿入部６９、角パイプ挿入部７０に角パイプ４２、角パイプ４３を挿入する事により、図５ｃのような構成となる。 Further, by inserting the square pipe 42 and the square pipe 43 into the square pipe insertion portion 69 and the square pipe insertion portion 70 of FIG. 5B, the configuration shown in FIG. 5C is obtained.

図６及至図８は、このように構成された樹脂仮枠１と角パイプ４２、角パイプ４３と固定金具４０が、外壁仮枠としてどのように構築されるかを示す。 FIGS. 6 to 8 show how the resin temporary frame 1 and the square pipe 42, the square pipe 43 and the fixing bracket 40 constructed as described above are constructed as the outer wall temporary frame.

図６の、図６ａは、図１で説明した樹脂仮枠１の欠き込み部１７の平面断面図である。パネル部９の１部が欠き込まれている。図６ｂは、図６ａで説明した樹脂仮枠１に、図５の、図５ａで説明した固定部材５１にネジ受部材６４を溶接で固定し、その固定部材５１をウェブ面８にボルト５９とナット６０で固定した状態を示す。図６ｃは、図６ｂで説明した樹脂仮枠１に、図５の、図５ｃで説明した角パイプ４２、角パイプ４３に、図５ａで説明した角パイプ固定部材４４を装着した後、角パイプ固定部材４４を固定部材５１に差し込んだ後、Ｌ形固定棒４１を角パイプ固定部材４４の挿入穴４８に挿入して樹脂仮枠１と角パイプ４２、角パイプ４３を固定した状態を示す。図６ｄは、図６ｃで説明した樹脂仮枠１の固定金具４０のネジ受部材６４のネジ穴６３に、中空パイプ６５に挿入されたセパレーター６７を取付けた状態を示す。 6a of FIG. 6 is a cross-sectional plan view of the notched portion 17 of the temporary resin frame 1 described in FIG. One part of the panel part 9 is cut out. FIG. 6B is a plan view of the resin temporary frame 1 described with reference to FIG. 6A. The screw receiving member 64 is fixed to the fixing member 51 illustrated in FIG. The state fixed with the nut 60 is shown. FIG. 6C shows a case where the square pipe fixing member 44 described in FIG. 5A is mounted on the square pipe 42 and the square pipe 43 described in FIG. 5C on the resin temporary frame 1 described in FIG. After the fixing member 44 is inserted into the fixing member 51, the L-shaped fixing rod 41 is inserted into the insertion hole 48 of the square pipe fixing member 44 and the temporary resin frame 1, the square pipe 42, and the square pipe 43 are fixed. FIG. 6d shows a state in which the separator 67 inserted into the hollow pipe 65 is attached to the screw hole 63 of the screw receiving member 64 of the fixing bracket 40 of the temporary resin frame 1 described in FIG. 6c.

図７は、図６の図６ｄで説明した樹脂仮枠１と固定金具４０と角パイプ４２、角パイプ４３の結合状態を分かり易く説明するため、結合状態を平面図、正面図、側面図の三角法で示す。 FIG. 7 is a plan view, a front view, and a side view of the joined state for easy understanding of the joined state of the temporary resin frame 1, the fixing bracket 40, the square pipe 42, and the square pipe 43 described with reference to FIG. Shown in trigonometry.

図８は、図１及至図７で説明してきた複数の樹脂仮枠１と固定金具４０と角パイプ４２とを結合した、建物の外壁を構築するための外壁外側仮枠７９と、外壁内側仮枠７８をセパレーター６７と中空パイプ６５で結合した状態を示す。外壁内側仮枠７８は、一般的な鉄筋コンクリート住宅を造る際に用いられている仮枠と同一の、せき板８２に根太８０を固定した仮枠を、単管８１と一般的なフォームタイ８３で固定したものである。なお、この場合、ナット７７でフォームタイ８３を締付けた際に、中空パイプ６５がせき板８２に喰い込むのを防ぐため、せき板８２と中空パイプ６５の間にワッシャー８４を挿入する。このように構成された仮枠に、生コンクリートを打込み、コンクリートが固まった後に、仮枠をコンクリートから剥離する際は、外壁内側仮枠７８を固定しているセパレーター６７の先端部の回動部７１をスパナ等を使って回転させる事により、図５で説明したセパレーター６７とネジ受け部材６４との契合が解かれ、図８で説明した外壁外側仮枠７９と外壁コンクリートとが剥離状態となり外壁外側仮枠７９は自由に移動可能な状態となると共に、中空パイプ６５は外壁コンクリートの中に取り残されるため、取り残された中空パイプ６５の穴にコーキング等の詰め物を詰め込んで雨水の浸入を防止する。なお、外壁内側仮枠７８の仮枠は、従来の一般的な解体方法により解体される。 FIG. 8 shows an outer wall outer temporary frame 79 for constructing an outer wall of a building, in which the plurality of resin temporary frames 1, the fixing bracket 40, and the square pipe 42 described in FIGS. 1 to 7 are combined, and an outer wall inner temporary frame. A state in which the frame 78 is coupled by the separator 67 and the hollow pipe 65 is shown. The outer wall inner temporary frame 78 is the same temporary frame used when constructing a general reinforced concrete house. It is fixed. In this case, a washer 84 is inserted between the dam plate 82 and the hollow pipe 65 to prevent the hollow pipe 65 from biting into the dam plate 82 when the foam tie 83 is tightened with the nut 77. When the ready-mixed concrete is poured into the temporary frame configured in this way and the concrete is solidified, when the temporary frame is peeled off from the concrete, the rotating portion at the tip of the separator 67 fixing the outer-wall inner temporary frame 78 By rotating 71 with a spanner or the like, the engagement between the separator 67 and the screw receiving member 64 described with reference to FIG. 5 is released, and the outer wall outer temporary frame 79 and outer wall concrete described with reference to FIG. The outer temporary frame 79 is in a freely movable state, and the hollow pipe 65 is left in the outer wall concrete. Therefore, the left hollow pipe 65 is filled with a filling such as caulking to prevent intrusion of rainwater. . The temporary frame of the outer wall inner temporary frame 78 is disassembled by a conventional general disassembly method.

図９は、図１で説明した樹脂仮枠１の弓状部１６と台形部１５の表面に、外壁の外側のコンクリートの表面に細い筋を形成するために、押出成形する金型の表面に、細い筋を入れ、その金型を使って押出成形された樹脂仮枠１を平面図と正面図で示す。このように押出成形された樹脂仮枠１の表面に細い筋を入れる事により、生コンクリートの中に含まれる空気を生コンクリートの外に排出する事が可能となる。なお、図９の拡大図で示したように、樹脂仮枠の弓状部１６と台形部１５に成形する筋８５のサイズは、表面の切り込み幅は０．２ミリメートル、深さは０．５ミリメートル位の三角形状の筋８５が適切である。また、このような筋８５を付ける事により、従来の無機質な平面形状の外壁コンクリート面に比べて、コンクリートの表面の意匠に変化を与える事が出来る。 9 shows the surface of the mold to be extruded to form thin streaks on the surface of the concrete outside the outer wall on the surface of the arcuate portion 16 and the trapezoidal portion 15 of the resin temporary frame 1 described in FIG. A thin temporary streak and a resin temporary frame 1 extruded using the mold are shown in a plan view and a front view. By putting thin stripes on the surface of the resin temporary frame 1 thus extruded, it is possible to discharge the air contained in the ready-mixed concrete to the outside of the ready-mixed concrete. As shown in the enlarged view of FIG. 9, the size of the streaks 85 formed on the arcuate portion 16 and the trapezoidal portion 15 of the temporary resin frame is such that the cut width of the surface is 0.2 mm and the depth is 0.5 mm. A millimeter-like triangular streak 85 is appropriate. Further, by adding such a streak 85, the design of the concrete surface can be changed as compared with the conventional inorganic planar outer wall concrete surface.

図１０と図１１は、複数個の樹脂仮枠１を横方向に並べて、１枚の仮枠として構成するため、複数個の樹脂仮枠１の上部と下部を固定するために取付ける上部固定部材８６と下部固定部材９５を斜視図で示す。上部固定部材８６は薄板鋼板をＬ字形に成形すると共に、その下部に溝差込部８９をコの字形に成形する。このようにコの字形に成形されたコの字部分の下部を、樹脂仮枠１に食い込ませて上部固定部材８６と複数個の樹脂仮枠１を固定するため、樹脂仮枠１のパネル部６とパネル部９に、図１０で示すような固定溝９１を掘り、さらに、上部固定部材８６を樹脂仮枠１に固定するために、上部固定部材８６の下部にネジ穴（図示せず）が開けられたネジ固定部８８、ネジ固定部９８を取付け、ネジ固定部８８とネジ固定部９８を樹脂仮枠１の図１で説明したウェブ面７とウェブ面１１にネジ８７、ネジ９０で固定する。さらに、下部固定部材９５は、前記、上部固定部材８６で説明したのと同様に、上部固定部材８６を逆さにした状態で、複数個の樹脂仮枠１の下部に掘り込まれた固定溝９７に溝差込部９９が差し込まれ、ネジ穴（図示せず）が開けられたネジ固定部９３、ネジ固定部９４を樹脂仮枠１の図１で説明したウェブ面７とウェブ面１１にネジ９２とネジ９６で固定する。このようにして上部固定部材８６と下部固定部材９５は樹脂仮枠１に固定され、図１１に示すような斜視図の形状となる。 FIGS. 10 and 11 show an upper fixing member that is attached to fix the upper and lower portions of the plurality of resin temporary frames 1 in order to arrange the plurality of resin temporary frames 1 in the horizontal direction to form a single temporary frame. 86 and the lower fixing member 95 are shown in a perspective view. The upper fixing member 86 forms a thin steel plate into an L shape, and a groove insertion portion 89 is formed into a U shape at the lower portion thereof. In order to fix the upper fixing member 86 and the plurality of resin temporary frames 1 by biting the lower part of the U-shaped portion formed in the U shape into the resin temporary frame 1 in this way, the panel portion of the resin temporary frame 1 6 and the panel portion 9 are digged with a fixing groove 91 as shown in FIG. 10, and a screw hole (not shown) is formed below the upper fixing member 86 in order to fix the upper fixing member 86 to the resin temporary frame 1. The screw fixing portion 88 and the screw fixing portion 98 are opened, and the screw fixing portion 88 and the screw fixing portion 98 are attached to the web surface 7 and the web surface 11 described with reference to FIG. Fix it. Further, the lower fixing member 95 is a fixing groove 97 dug in the lower part of the plurality of temporary resin frames 1 in a state where the upper fixing member 86 is turned upside down, as described above with respect to the upper fixing member 86. A screw fixing portion 93 and a screw fixing portion 94 in which a groove insertion portion 99 is inserted and a screw hole (not shown) is opened are screwed onto the web surface 7 and the web surface 11 of the resin temporary frame 1 described with reference to FIG. 92 and screws 96 are used for fixing. In this way, the upper fixing member 86 and the lower fixing member 95 are fixed to the resin temporary frame 1 and have a perspective view as shown in FIG.

図１２は、図１１のように構成された複数個の仮枠を、図７で説明したように固定金具４０と仮枠外端太（角パイプ４２、角パイプ４３）で連結固定した状態を示すと共に、つづいて、クレーン等（図示せず）で連結固定した仮枠を吊り上げるための構造について説明する。 FIG. 12 shows a state in which a plurality of temporary frames configured as shown in FIG. 11 are connected and fixed by the fixing bracket 40 and the outer thick end of the temporary frame (square pipe 42, square pipe 43) as described in FIG. Then, a structure for lifting a temporary frame connected and fixed by a crane or the like (not shown) will be described.
