以下、本発明の実施の形態にかかる型枠固定金具１について説明する。図１は、型枠固定金具１を示す斜視図である。型枠固定金具１は、型枠を固定するための金具であって、平板部３、壁部５等から構成される。 Hereinafter, the mold fixing bracket 1 according to the embodiment of the present invention will be described. FIG. 1 is a perspective view showing a mold fixing bracket 1. The mold fixing metal fitting 1 is a metal fitting for fixing the mold, and includes a flat plate portion 3, a wall portion 5, and the like.
平板部３は、略平坦な部位であり、平板部３の端部に、平板部３に対して略垂直に起立する一対の壁部５が形成される。一対の壁部５は、互いに所定の角度で形成される。図示した例では、一対の壁部５同士が、略９０度の角度で形成される。 The flat plate portion 3 is a substantially flat portion, and a pair of wall portions 5 are formed at the end of the flat plate portion 3 so as to stand substantially perpendicular to the flat plate portion 3. The pair of wall portions 5 are formed at a predetermined angle with respect to each other. In the illustrated example, the pair of wall portions 5 are formed at an angle of approximately 90 degrees.
平板部３の一部には、直線部７が形成される。直線部７は、それぞれの壁部５と略平行に形成される。すなわち、一対の直線部７同士は、一対の壁部５の形成角度と同様の角度で形成される。なお、壁部５と直線部７とは所定の間隔をあけて形成される。壁部５と直線部７との間隔は、型枠の厚みに対応する。 A straight portion 7 is formed on a part of the flat plate portion 3. The straight line portion 7 is formed substantially parallel to each wall portion 5. That is, the pair of linear portions 7 are formed at an angle similar to the formation angle of the pair of wall portions 5. In addition, the wall part 5 and the linear part 7 are formed at predetermined intervals. The distance between the wall portion 5 and the linear portion 7 corresponds to the thickness of the mold.
それぞれの直線部７の延長線上であって、それぞれの延長線の交点近傍には、孔９が形成される。孔９は、例えば円形の貫通孔である。 A hole 9 is formed on the extension line of each straight line portion 7 and in the vicinity of the intersection of each extension line. The hole 9 is, for example, a circular through hole.
型枠固定金具１は、例えば、金属板からプレス加工によって一体で構成することができる。なお、平板部３や壁部５に、型枠等を固定するための固定用孔を形成してもよい。 The mold fixing bracket 1 can be integrally formed from a metal plate by press working, for example. A fixing hole for fixing a mold or the like may be formed in the flat plate portion 3 or the wall portion 5.
次に、型枠固定金具１を用い、捨てコンクリート上に型枠を設置する方法について説明する。まず、図２に示すように、コンクリート１１の上面の型枠の設置位置に墨出しを行い、墨線１３を形成する。墨線１３は、例えば、施工予定のコンクリート基礎のコンクリート打設外面位置に形成される。すなわち、墨線１３が、型枠の内面位置となる。 Next, a method for installing the mold on the discarded concrete using the mold fixing bracket 1 will be described. First, as shown in FIG. 2, inking is performed at the installation position of the formwork on the upper surface of the concrete 11 to form inking lines 13. The black line 13 is formed, for example, at a concrete placement outer surface position of a concrete foundation scheduled to be constructed. That is, the black line 13 is the inner surface position of the mold.
ここで、コンクリート基礎の打設範囲を囲むように複数枚の型枠が設置される。したがって、型枠同士を所定の角度で突き合せる部位が生じる。この場合、墨線１３同士が所定の角度で交差することになる。 Here, a plurality of molds are installed so as to surround a concrete foundation placing range. Therefore, the site | part which abuts mold forms at a predetermined angle arises. In this case, the black lines 13 intersect at a predetermined angle.
型枠固定金具１は、孔９を有するため、墨線１３の交点１５を、孔９の略中心の位置に合わせて型枠固定金具１を配置することで、確実に型枠設置位置に型枠固定金具１を配置することができる。この際、型枠固定金具１は、それぞれの直線部７が、それぞれの墨線１３の直線の位置に合うように調整される。この状態で、平板部３に形成された固定用孔（図示省略）によって、型枠固定金具１がコンクリート１１に固定される。なお、コンクリート１１へ固定するための固定用孔は、少なくとも２カ所あることが望ましく、その内の一つを、孔９で代用してもよい。 Since the mold fixing bracket 1 has the hole 9, the mold fixing bracket 1 is arranged at the position where the mold is installed by positioning the intersection 15 of the black line 13 to the position of the approximate center of the hole 9. The fixture 1 can be arranged. At this time, the mold fixing metal fitting 1 is adjusted so that the respective straight portions 7 are aligned with the positions of the straight lines of the respective black lines 13. In this state, the mold fixing bracket 1 is fixed to the concrete 11 by fixing holes (not shown) formed in the flat plate portion 3. In addition, it is desirable that there are at least two fixing holes for fixing to the concrete 11, and one of them may be substituted by the hole 9.
次に、図３に示すように、型枠固定金具１に型枠１７を配置する。この際、型枠１７の背面の一部は、壁部５の内面に接触させ、一対の型枠１７の突合せ部が、孔９の略中心（交点１５）の位置に来るように調整する。このようにすることで、型枠１７の設置位置を容易に把握することができ、確実に型枠１７を所望の位置に配置することができる。なお、型枠１７は、木製であってもよく、金属製であってもよい。また、型枠１７は、壁部５に形成された固定用孔（図示省略）によって、型枠固定金具１に固定される。 Next, as shown in FIG. 3, the mold 17 is disposed on the mold fixing bracket 1. At this time, a part of the rear surface of the mold 17 is brought into contact with the inner surface of the wall 5, and the abutting portions of the pair of molds 17 are adjusted so as to be located at the approximate center (intersection 15) of the hole 9. By doing in this way, the installation position of the formwork 17 can be grasped | ascertained easily and the formwork 17 can be arrange | positioned in a desired position reliably. Note that the mold 17 may be made of wood or metal. Further, the mold 17 is fixed to the mold fixing bracket 1 by a fixing hole (not shown) formed in the wall 5.
次に、図４に示すように、一対の型枠１７の上部に、型枠固定金具１を設置する。この際、孔９からは、型枠１７同士の突合せ部を視認することができるため、型枠１７のずれなどを抑制することができる。なお、型枠固定金具１は、壁部５や平板部３に形成された固定用孔（図示省略）によって、型枠１７に固定される。 Next, as shown in FIG. 4, the mold fixing bracket 1 is installed on top of the pair of molds 17. At this time, since the butted portion between the molds 17 can be visually recognized from the hole 9, the shift of the mold 17 can be suppressed. Note that the mold fixing bracket 1 is fixed to the mold 17 by fixing holes (not shown) formed in the wall portion 5 and the flat plate portion 3.
図５は、型枠１７の設置状態を示す正面図である。なお、型枠１７同士の突合せ部（コーナー部）には、別途、Ｌアングルなどの補強金具を外側から設置して、隙間を埋めてもよい。また、打設されるコンクリート基礎の角が９０度以外の場合には、壁部５および直線部７の形成角度を、当該角度に合わせて設計すればよい。 FIG. 5 is a front view showing an installation state of the mold 17. In addition, a reinforcing metal fitting such as an L angle may be separately installed from the outside at the abutting portion (corner portion) between the molds 17 to fill the gap. Further, when the corner of the concrete foundation to be placed is other than 90 degrees, the formation angle of the wall portion 5 and the straight portion 7 may be designed according to the angle.
以上、本実施の形態によれば、型枠１７の設置位置を容易に把握することができるため、型枠固定金具１を容易に精度よく設置することができる。また、型枠固定金具１の壁部５に沿って型枠１７を配置し、型枠１７の先端を孔９に合わせればよいため、型枠１７の位置合わせが容易である。このため、型枠１７を精度よく配置することができる。 As mentioned above, according to this Embodiment, since the installation position of the mold 17 can be grasped | ascertained easily, the mold fixing bracket 1 can be installed easily and accurately. Further, since the mold frame 17 may be disposed along the wall portion 5 of the mold fixing bracket 1 and the tip of the mold frame 17 may be aligned with the hole 9, the positioning of the mold frame 17 is easy. For this reason, the formwork 17 can be arrange | positioned accurately.
また、型枠１７の上端部にも、型枠固定金具１を配置することで、型枠１７のずれを抑制することができる。この際、孔９によって、型枠１７の突合せ位置を視認することができるため、精度よく、型枠１７を固定することができる。 Moreover, the displacement of the mold 17 can be suppressed by arranging the mold fixing bracket 1 at the upper end of the mold 17. In this case, since the butting position of the mold 17 can be visually recognized by the hole 9, the mold 17 can be fixed with high accuracy.
また、平板部３に固定用孔を形成することで、型枠固定金具１をコンクリート１１上に固定する際に使用することができる。また、平板部３や壁部５に固定用孔を形成することで、型枠１７と型枠固定金具１とを固定する際に使用することができる。 Further, by forming a fixing hole in the flat plate portion 3, it can be used when the mold fixing bracket 1 is fixed on the concrete 11. Further, by forming fixing holes in the flat plate portion 3 and the wall portion 5, it can be used when the mold 17 and the mold fixing bracket 1 are fixed.
次に、第２の実施形態について説明する。図６は、第２の実施形態にかかる型枠固定金具１ａの斜視図である。なお、以下の説明において、型枠固定金具１等と同一の機能を奏する構成については、図１〜図５と同一の符号を付し、重複する説明を省略する。 Next, a second embodiment will be described. FIG. 6 is a perspective view of the mold fixing bracket 1a according to the second embodiment. In the following description, the same reference numerals as those in FIGS. 1 to 5 are given to the components having the same functions as those of the mold fixing bracket 1 and the like, and redundant description is omitted.
型枠固定金具１ａは、型枠固定金具１とほぼ同様の構成であるが、突起部１９が形成される点で異なる。また、突起部１９の形成に伴い、孔９に代えて、切欠き部９ａが形成される点で異なる。 The mold fixing bracket 1a has substantially the same configuration as the mold fixing bracket 1, but is different in that a projection 19 is formed. Further, it differs in that a notch 9a is formed in place of the hole 9 with the formation of the protrusion 19.
突起部１９は、平板部３に対して略垂直に起立し、それぞれの壁部５と対向する位置に形成される。また、壁部５に対向する突起部１９の位置は、直線部７の延長線上に位置する。すなわち、壁部５と直線部７との間の距離と、壁部５と突起部１９との間の距離はほぼ一致する。 The projecting portions 19 stand substantially perpendicular to the flat plate portion 3 and are formed at positions facing the respective wall portions 5. In addition, the position of the protrusion 19 that faces the wall 5 is located on the extended line of the straight portion 7. That is, the distance between the wall part 5 and the straight line part 7 and the distance between the wall part 5 and the projection part 19 are substantially the same.
なお、図示した例では、突起部１９は平板部３の一部が折曲げられて形成される。この際、折曲げ部が、壁部５に略垂直な方向となるように、突起部１９が起立する。この場合には、突起部１９と壁部５は略垂直な向きとなる。なお、突起部１９の形成位置や形成方向は、図示した例には限られない。 In the illustrated example, the protruding portion 19 is formed by bending a part of the flat plate portion 3. At this time, the protruding portion 19 rises so that the bent portion is in a direction substantially perpendicular to the wall portion 5. In this case, the protrusion 19 and the wall 5 are oriented substantially perpendicularly. In addition, the formation position and formation direction of the protrusion 19 are not limited to the illustrated example.
切欠き部９ａは、直線部７の延長線の交点近傍に形成される。切欠き部９ａは、前述した孔９と同様の機能を奏する。すなわち、直線部７の延長線の交点近傍に、孔９または切欠き部９ａのような、平板部３に対する貫通部が形成されればよい。 The notch 9 a is formed in the vicinity of the intersection of the extension lines of the straight line portion 7. The notch 9a has the same function as the hole 9 described above. That is, a through portion for the flat plate portion 3 such as the hole 9 or the notch portion 9a may be formed in the vicinity of the intersection of the extension lines of the straight portion 7.
次に、型枠固定金具１ａを用い、コンクリート上に型枠１７を設置する方法について説明する。まず、図７に示すように、コンクリート１１の上面の型枠の設置位置に墨出しを行い、墨線１３を形成する。墨線１３は、例えば、施工予定のコンクリート基礎のコンクリート打設外面位置に形成される。すなわち、墨線１３が、型枠の内面位置となる。 Next, a method for installing the mold 17 on the concrete using the mold fixing bracket 1a will be described. First, as shown in FIG. 7, inking is performed at the installation position of the mold on the upper surface of the concrete 11 to form the inking line 13. The black line 13 is formed, for example, at a concrete placement outer surface position of a concrete foundation scheduled to be constructed. That is, the black line 13 is the inner surface position of the mold.
次に、前述したように、墨線１３の交点１５を、切欠き部９ａの略中心の位置に合わせて型枠固定金具１ａを配置する。この状態で、平板部３に形成された固定用孔（図示省略）によって、型枠固定金具１ａがコンクリート１１に固定される。 Next, as described above, the mold fixing metal fitting 1a is arranged by matching the intersection 15 of the black line 13 with the position of the approximate center of the notch 9a. In this state, the mold fixing bracket 1 a is fixed to the concrete 11 by fixing holes (not shown) formed in the flat plate portion 3.
次に、図８に示すように、型枠固定金具１ａに型枠１７を配置する。この際、型枠１７の背面の一部を、壁部５の内面に接触させ、壁部５と突起部１９との間に型枠１７を挿入する。また、一対の型枠１７の突合せ部が、切欠き部９ａの略中心（交点１５）の位置に来るように調整する。このようにすることで、確実に型枠１７を所望の位置に配置することができる。なお、型枠１７は、壁部５に形成された固定用孔（図示省略）によって、型枠固定金具１ａに固定される。 Next, as shown in FIG. 8, the mold 17 is placed on the mold fixing bracket 1a. At this time, a part of the back surface of the mold 17 is brought into contact with the inner surface of the wall 5, and the mold 17 is inserted between the wall 5 and the protrusion 19. Moreover, it adjusts so that the butt | matching part of a pair of formwork 17 may come to the position of the approximate center (intersection 15) of the notch part 9a. By doing in this way, the formwork 17 can be reliably arrange | positioned in a desired position. The mold 17 is fixed to the mold fixing bracket 1a by a fixing hole (not shown) formed in the wall 5.
次に、図９に示す様に、一対の型枠１７の上部に、型枠固定金具１ａを設置する。この際、切欠き部９ａからは、型枠１７同士の突合せ部を視認することができるため、型枠１７のずれなどを抑制することができる。なお、型枠固定金具１ａは、壁部５や平板部３に形成された固定用孔（図示省略）によって、型枠１７に固定される。 Next, as shown in FIG. 9, the mold fixing bracket 1 a is installed on top of the pair of molds 17. At this time, since the butt portion between the molds 17 can be visually recognized from the notch 9a, the shift of the mold 17 and the like can be suppressed. The mold fixing metal fitting 1a is fixed to the mold frame 17 by fixing holes (not shown) formed in the wall portion 5 and the flat plate portion 3.
以上、第２の実施の形態によれば、第１の実施形態と同様の効果を得ることができる。また、突起部１９が形成されるため、型枠１７の位置決めがより容易となり、位置ずれを抑制することができる。 As described above, according to the second embodiment, the same effects as those of the first embodiment can be obtained. Moreover, since the projection part 19 is formed, the positioning of the mold 17 becomes easier and the displacement can be suppressed.
以上、添付図を参照しながら、本発明の実施の形態を説明したが、本発明の技術的範囲は、前述した実施の形態に左右されない。当業者であれば、特許請求の範囲に記載された技術的思想の範疇内において各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。 As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention.
