Description

本発明は、梁貫通スリーブの固定方法及び固定治具に関する方法であり、特に、スリーブを正確かつ安定に固定するための固定方法および固定治具に関する。   The present invention relates to a method for fixing a beam penetration sleeve and a fixing jig, and more particularly, to a fixing method and a fixing jig for fixing a sleeve accurately and stably.

梁貫通スリーブ(以下、スリーブ)は、電線や水道管などのライフラインを通すための孔であり、当該スリーブを設置する際には、高精度の位置決めが要求されている。スリーブの取り付け場所によっては、数センチメートルのスリーブの位置ずれが施工上の不具合になり、スリーブを再設置するためにコンクリートを開け直すなどの再工事になることもある。   The beam penetration sleeve (hereinafter referred to as a sleeve) is a hole through which a lifeline such as an electric wire or a water pipe passes, and high-precision positioning is required when the sleeve is installed. Depending on where the sleeves are installed, the displacement of the sleeve of several centimeters may become a problem in construction, and re-construction such as reopening the concrete to re-install the sleeve may occur.

例えば、特許文献1には、スリーブ固定治具及び貫通孔の施工方法が開示されている。   For example, Patent Literature 1 discloses a sleeve fixing jig and a method for constructing a through hole.

特許文献1に記載された方法は、例えば、図9に示すように、鉄筋Rにスリーブ固定具1を設けることで、スリーブSを精度よく位置決めするものである。しかし、固定具の位置決め精度は、鉄筋の設置位置や固定具1の取り付け位置に依存するため、例えば、鉄筋の設置位置がコンクリート打設時にずれてしまった場合には、スリーブの位置もずれることになる。   In the method described in Patent Document 1, for example, as shown in FIG. 9, the sleeve S is positioned with high accuracy by providing the reinforcing member R with the sleeve fixture 1. However, since the positioning accuracy of the fixing tool depends on the installation position of the reinforcing bar and the mounting position of the fixing tool 1, for example, if the installation position of the reinforcing bar is shifted at the time of placing concrete, the position of the sleeve is also shifted. become.

図1は、本発明の一実施例による固定治具の概略図を示す。   FIG. 1 is a schematic view of a fixing jig according to an embodiment of the present invention.

本実施例の固定治具100は、主軸110と、複数の支持棒120と、穴おさえ具130と、可動部140を備える。   The fixing jig 100 according to the present embodiment includes a main shaft 110, a plurality of support rods 120, a hole holding member 130, and a movable part 140.

主軸110は、設置するスリーブの概ね中心に配置される。   The main shaft 110 is disposed approximately at the center of the sleeve to be installed.

複数の支持棒120は、主軸110に対して開くことでスリーブの内径にほぼ内接することにより、スリーブのぶれを抑えて固定する。それぞれの支持棒の長さは、等しくてもよい。また、本実施例のようにスリーブを固定するという技術的効果の観点からは、少なくとも2本の支持棒があればよい。   The plurality of support rods 120 are fixed to the sleeve 110 by restraining the sleeve from shaking by being inscribed in the inner diameter of the sleeve by opening with respect to the main shaft 110. The length of each support bar may be equal. In addition, from the viewpoint of the technical effect of fixing the sleeve as in this embodiment, it is sufficient if there are at least two support bars.

なお、主軸110や支持棒120には、任意の材料を使用できるが、プラスチック、鉄やアルミニウムなど、ある程度の剛性を有した材料を用いてよい。   Although any material can be used for the main shaft 110 and the support rod 120, a material having a certain degree of rigidity, such as plastic, iron, or aluminum, may be used.

穴おさえ具130は、主軸110を型枠に通した後に、主軸110をスリーブの中心に固定するために用いる。なお、穴おさえ具130は、主軸110が軸方向に動くことを固定できるように構成されてもよい。なお、穴おさえ具130には、任意の材料が使用できるが、例えば、ゴムなど、ある程度の弾性を有した材料を用いてもよい。   The hole stopper 130 is used to fix the main shaft 110 to the center of the sleeve after passing the main shaft 110 through the mold. Note that the hole retainer 130 may be configured to fix the movement of the main shaft 110 in the axial direction. Although any material can be used for the hole retainer 130, for example, a material having a certain degree of elasticity such as rubber may be used.

可動部140は、支持棒120の可動域を決める。可動部140の更に具体的な構成例は、図2で示す。   The movable part 140 determines the movable range of the support rod 120. A more specific configuration example of the movable portion 140 is shown in FIG.

図2(a)は、本発明の一実施例による可動部140の構成例を示す。   FIG. 2A shows a configuration example of the movable unit 140 according to an embodiment of the present invention.

図2(a)に示す本実施例の可動部140は、係止具141と、可動軸142と、複数の溝143と、ストッパ144で構成される。係止具141は、円錐の上部が切断された形状をしている。別の実施例として、係止具141は、その他任意の形状でもよい。   The movable portion 140 of this embodiment shown in FIG. 2A includes a locking tool 141, a movable shaft 142, a plurality of grooves 143, and a stopper 144. The locking tool 141 has a shape in which the upper part of the cone is cut. As another example, the locking device 141 may have any other shape.

係止具141の上部から側面にかけて、複数の溝143が形成されている。なお、溝143の数は、支持棒120の数に等しい若しくは多くてもよい。また、各溝143は、(主軸110が通る)中心軸に対して等角度になるように形成されてもよいが、異なる角度で配置されてもよい。   A plurality of grooves 143 are formed from the upper part to the side surface of the locking tool 141. Note that the number of grooves 143 may be equal to or greater than the number of support bars 120. Each groove 143 may be formed at an equal angle with respect to the central axis (through which the main shaft 110 passes), but may be arranged at different angles.

また、係止具141は、任意の材料が使用できるが、例えば、プラスチックやゴムなどのように、ある程度の弾性を有した材料を用いてもよい。当該材料を用いれば、通常の形態では、支持棒120は主軸110に対してある程度の角度αをなすが、人間の手などで支持棒全体を握ることによって、当該角度αを概ねゼロ度(主軸に対して概ね並行)にすることができる。これにより、後述するが、本実施例の固定治具が型枠の穴に入れやすくなり、型枠の穴に入れた後は、支持棒がスリーブ内で少し開くので、当該スリーブ内で支持棒を更に広げて固定することが容易になる。   Moreover, although arbitrary materials can be used for the locking tool 141, for example, a material having a certain degree of elasticity, such as plastic or rubber, may be used. If the material is used, the support rod 120 forms a certain angle α with respect to the main shaft 110 in a normal form. However, by gripping the entire support rod with a human hand or the like, the angle α is substantially zero degrees (main shaft In general). As a result, as will be described later, the fixing jig of the present embodiment can be easily put into the hole of the mold, and the support bar opens a little within the sleeve after being inserted into the hole of the mold, so the support bar within the sleeve It becomes easy to further expand and fix.

係止具141の側面には、複数の溝143の上を通るように、可動軸142が設置されている。また、可動軸142は、任意の材料が使用できるが、例えば、針金のような、ある程度の剛性を有しつつ形状の加工が容易な材料を用いてもよい。   A movable shaft 142 is installed on the side surface of the locking tool 141 so as to pass over the plurality of grooves 143. The movable shaft 142 may be made of any material, but may be made of a material that has a certain degree of rigidity and can be easily processed, such as a wire.

ストッパ144は、係止具141の上部に設置されており、ストッパの径は、係止具141との接地面の径よりも長い。本実施例のような可動部140を構成することにより、支持棒120が主軸100に対して概ね直角まで開くと、支持棒120がストッパ140に当たるので、それ以上の開きを止めることができる。   The stopper 144 is installed on the upper portion of the locking tool 141, and the diameter of the stopper is longer than the diameter of the ground contact surface with the locking tool 141. By configuring the movable part 140 as in the present embodiment, when the support bar 120 is opened to a substantially right angle with respect to the main shaft 100, the support bar 120 hits the stopper 140, so that further opening can be stopped.

支持棒120には、軸穴121が空いている。当該軸穴121が、可動軸142を通すように設置されることにより、支持棒120が可動軸142の周りを回転するように可動する。なお、軸穴121の形状は、丸型でもよく、可動軸142への取り付けが容易なカギ型でもよく、その他任意の形状でもよい。   The support rod 120 has a shaft hole 121. The shaft hole 121 is installed so as to pass the movable shaft 142, so that the support rod 120 is movable so as to rotate around the movable shaft 142. The shape of the shaft hole 121 may be a round shape, a key shape that can be easily attached to the movable shaft 142, or any other shape.

なお、溝143は、図2(b)に示すように、係止具141の上部から側面を通り下部にかけて形成するような構成でもよい。これにより、主軸110に対して、角度αが概ねゼロ度(主軸に対して概ね並行)から概ね直角までの任意の範囲で、支持棒が開く(可動する)ように構成できる。   The groove 143 may be configured to be formed from the upper part of the locking member 141 to the lower part through the side surface as shown in FIG. As a result, the support rod can be configured to open (movable) in an arbitrary range of the angle α with respect to the main shaft 110 from substantially zero degrees (substantially parallel to the main shaft) to a substantially right angle.

図3は、支持棒の末端(主軸から離れた側の一端)に返し123が形成された実施例を示している。返し123は、主軸120に対して開くように形成される。開く角度βは、本実施例においては任意でよいが、図5に示すような、支持棒が二段階で固定できるような別の実施例においては、支持棒の開く角度に依存して、支持棒120が開きやすいように、返しの角度βが決まってもよい。   FIG. 3 shows an embodiment in which a barb 123 is formed at the end of the support rod (one end away from the main shaft). The barb 123 is formed so as to open with respect to the main shaft 120. The opening angle β may be arbitrary in this embodiment, but in another embodiment in which the support bar can be fixed in two stages as shown in FIG. 5, the support angle depends on the opening angle of the support bar. The return angle β may be determined so that the bar 120 can be easily opened.

別の実施例として、返しを円弧状にしてもよく、更に好ましくは、図3(b)に示すように、返し側の一端が少なくとも半円以上を形成するような円弧でもよい。また、返し123は、図8Dで示すような工程で使用できるものであれば、任意の形状を形成してもよい。   As another example, the barb may be arcuate, and more preferably, as shown in FIG. 3 (b), the arcuate end may be at least a semicircle or more. Moreover, as long as the return | turn 123 can be used at a process as shown to FIG. 8D, you may form arbitrary shapes.

なお、返し123は、全ての支持棒に設けなくてもよく、任意の支持棒に設けてもよい。   Note that the barbs 123 may not be provided on all the support bars, and may be provided on any support bar.

図4は、本発明の一実施例による穴おさえ具130を示す。穴おさえ具130は、主軸110を型枠の穴に固定するための部材である。穴おさえ具130は、主軸110を型枠に通す穴と概ね同じ径の固定部131を有している。これにより、主軸110が横ずれする(軸方向に対して直角の方向に動く)ことを防ぐ。図4(a)に示すように、穴おさえ具130自身がスリーブの中に入り込まないように主軸が通る型枠の穴よりも大きな径を設けた押さえ部132が付加された構成でもよいが、図4(b)に示すように、押さえ部132がなくてもよい。また、穴おさえ具130の表面133の形状は、型枠の穴の形に依存するので、円形でも多角形でもよい。   FIG. 4 shows a hole retainer 130 according to one embodiment of the present invention. The hole presser 130 is a member for fixing the main shaft 110 to the hole of the mold. The hole retainer 130 has a fixing portion 131 having a diameter substantially the same as that of the hole through which the main shaft 110 is passed through the mold. This prevents the main shaft 110 from being laterally displaced (moving in a direction perpendicular to the axial direction). As shown in FIG. 4 (a), a configuration in which a holding part 132 having a larger diameter than the hole of the mold through which the main shaft passes is added so that the hole presser 130 itself does not enter the sleeve, As shown in FIG. 4B, the pressing portion 132 may not be provided. Moreover, since the shape of the surface 133 of the hole presser 130 depends on the shape of the hole in the mold, it may be circular or polygonal.

図5は、本発明の別の実施例を示す。図5(a)は、支持棒が、主軸に対して、概ね直角(90度)まで開いているが、図5(b)のように、角度αが所定の(1つまたは複数の)鋭角で支持棒が固定されるように構成されてもよい。更に、主軸110は、穴おさえ具130に対して主軸100を軸方向(スリーブ内部へ向かう方向など)に固定するために、図5(a)のように支持棒120が主軸110に対して概ね直角で固定できるような穴おさえ具留め181や、支持棒120が主軸110に対して角度αで固定できるような図5(b)のような穴おさえ具留め182を備えてもよい。ここで、穴おさえ具留め181、182は、主軸110の中に手動で押し込むことができるにように構成されてもよい。また、主軸110内部にバネを設けておき、穴おさえ具留め181、182が主軸110に対して押し込まれる力がなくなると、当該バネの力により主軸110の外側方向に突出するように構成されてもよい。そして、図5(a)(b)のように、穴おさえ具留め181、182を用いて主軸110を軸方向に固定することによって、二段階(または図示しないが穴おさえ具留めの数に応じて複数段階)の角度で支持棒120が固定できれば、1つの固定治具で異なる内径φ1、φ2のスリーブ210、220に用いることができる。例えば、スリーブの内径は、75、100、125、150、175、200ミリメートルなどが一般的な既製品として販売されているので、支持棒が、これら内径のいくつかを形成できるような角度αを設定してもよい。また、穴おさえ具留め181、182の別の実施例として、結束バンドなどの任意の留め具が主軸に固定できるように構成してもよい。このような実施例の場合は、任意の角度αで支持棒120を固定することができるので、1つの固定治具で複数の内径のスリーブに用いることができる。   FIG. 5 shows another embodiment of the present invention. In FIG. 5 (a), the support rod is open to a substantially right angle (90 degrees) with respect to the main axis, but as shown in FIG. 5 (b), the angle α is a predetermined acute angle or angles. The support rod may be configured to be fixed. Further, in order to fix the main shaft 100 in the axial direction (the direction toward the inside of the sleeve, etc.) with respect to the hole retainer 130, the main shaft 110 has a support rod 120 that is generally positioned with respect to the main shaft 110 as shown in FIG. A hole holder 181 that can be fixed at a right angle, and a hole holder 182 as shown in FIG. 5B that can be fixed to the main shaft 110 at an angle α may be provided. Here, the hole retainers 181, 182 may be configured to be manually pushed into the main shaft 110. In addition, a spring is provided inside the main shaft 110, and when the force to press the hole retainer fasteners 181 and 182 against the main shaft 110 is eliminated, the spring is configured to protrude outward from the main shaft 110. Also good. Then, as shown in FIGS. 5 (a) and 5 (b), the main shaft 110 is fixed in the axial direction by using the hole retainer fasteners 181 and 182, so that the two stages (or the number of hole retainer fasteners depending on the number of hole retainer fasteners is not shown). If the support rod 120 can be fixed at an angle of a plurality of stages, it can be used for the sleeves 210 and 220 having different inner diameters φ1 and φ2 with one fixing jig. For example, the sleeve inner diameters 75, 100, 125, 150, 175, 200 millimeters, etc. are sold as common off-the-shelf products, so the angle α should be such that the support bar can form some of these inner diameters. It may be set. Further, as another example of the hole stopper fasteners 181 and 182, an arbitrary fastener such as a binding band may be fixed to the main shaft. In such an embodiment, since the support rod 120 can be fixed at an arbitrary angle α, it can be used for a sleeve having a plurality of inner diameters with a single fixing jig.

図6は、本発明の別の実施例を示す。本実施例は、支持棒が主軸に対して概ね直角に開いているときに適用できる。本実施例においては、少なくとも4本の支持棒120を備えている。図6では4本の支持棒120を備えた実施例を示しているが、少なくとも3本の支持棒があれば、スリーブの外側のいずれの方向からの圧力に対しても安定してスリーブを固定し続ける技術的効果もある。   FIG. 6 shows another embodiment of the present invention. This embodiment can be applied when the support bar is opened at a substantially right angle to the main axis. In this embodiment, at least four support rods 120 are provided. FIG. 6 shows an embodiment having four support rods 120. However, if there are at least three support rods, the sleeve can be stably fixed against pressure from any direction outside the sleeve. There is also a technical effect that continues.

各支持棒120には、布などの平面の生地150が取りつけられている。このような生地150を設けることにより、将来、治具でスリーブを固定した後に、スリーブの外側にコンクリートが流し込まれると、隙間からスリーブ内部にコンクリートが流れ込むことを防ぐことができる。すなわち、スリーブ内に、流れ込んだコンクリートが固まって、スリーブ内に異物として残ることを防ぐことができる。   A flat fabric 150 such as cloth is attached to each support rod 120. By providing such a dough 150, if concrete is poured into the outside of the sleeve after the sleeve is fixed with a jig in the future, the concrete can be prevented from flowing into the sleeve from the gap. That is, it is possible to prevent the concrete that has flowed into the sleeve from solidifying and remaining as foreign matter in the sleeve.

なお、本実施例の生地の材料は、任意でよいが、布やビニールなど、ある程度の柔軟性などがあればよい。   In addition, the material of the cloth of the present embodiment may be arbitrary, but it is only necessary to have a certain degree of flexibility such as cloth or vinyl.

図7は、本実施例の更に別の実施例を示す。本実施例においては、支持棒120のおおよそ中央部から外側の位置180から主軸110の開閉具170へ支え棒160が取り付けられている。開閉具170を主軸110に沿って上下動させることにより、支え棒160を介して、支持棒120の開閉が容易になる。   FIG. 7 shows still another embodiment of the present embodiment. In the present embodiment, a support bar 160 is attached to the opening / closing tool 170 of the main shaft 110 from a position 180 outside the center of the support bar 120. By moving the opening / closing tool 170 up and down along the main shaft 110, the support rod 120 can be easily opened and closed via the support rod 160.

図8A−8Dは、本発明の固定治具の使用方法の一例を示す。本実施例では、返し123が支持棒120に取り付けられている固定治具の使用方法の一例を示す。   8A-8D show an example of how to use the fixture of the present invention. In this embodiment, an example of how to use the fixing jig in which the barbs 123 are attached to the support rod 120 will be described.

図8Aは、主軸110が、型枠の穴を突き抜けて、スリーブの内部に入っている状態から、主軸110を型枠方向に引き戻している図を示す。   FIG. 8A shows a view in which the main shaft 110 is pulled back in the direction of the mold from a state where the main shaft 110 penetrates the hole of the mold and enters the inside of the sleeve.

支持棒120の返し123が型枠に当たると、図8Bに示すように、主軸110を戻す力に対して、支持棒120が開く方向に動き出す。   When the barb 123 of the support bar 120 hits the formwork, as shown in FIG. 8B, the support bar 120 starts to move in the opening direction with respect to the force for returning the main shaft 110.

図8Cは、穴おさえ具130を型枠に嵌め込み、主軸100を固定する図を示す。   FIG. 8C shows a view in which the hole retainer 130 is fitted into the mold and the main shaft 100 is fixed.

そして、図8Dに示すように、支持棒120が概ね直角に開いたところで、主軸110を引き出す方向に動かすことができなくなる。このとき、複数の支持棒120が作り出す径は、スリーブの内径に概ね等しくなっている。また、返し123が、スリーブの内側に当たるので、スリーブの固定を一層安定にする。スリーブを固定治具で固定した後は、コンクリートを流し込む。コンクリートが固まった後には、型枠300を外す。型枠300と一緒に、固定治具100も外せる。すなわち、本実施例の固定治具100を繰り返し使用することができる。   Then, as shown in FIG. 8D, when the support rod 120 is opened at a substantially right angle, the main shaft 110 cannot be moved in the pulling-out direction. At this time, the diameter produced by the plurality of support bars 120 is approximately equal to the inner diameter of the sleeve. In addition, since the barb 123 hits the inside of the sleeve, the fixing of the sleeve is further stabilized. After fixing the sleeve with the fixing jig, pour concrete. After the concrete has hardened, the formwork 300 is removed. The fixing jig 100 can be removed together with the mold 300. That is, the fixing jig 100 of the present embodiment can be used repeatedly.

本実施例の固定治具を使用することにより、支持棒が、型枠の表面に沿って固定されるので、主軸は、型枠の面に対して直角方向になる。また、補強具を使用することなく、スリーブを固定することができる利点もある。   By using the fixing jig of this embodiment, the support rod is fixed along the surface of the mold, so that the main axis is in a direction perpendicular to the surface of the mold. There is also an advantage that the sleeve can be fixed without using a reinforcing tool.

なお、本発明の一実施例による固定治具を用いた施工方法では、スリーブを両面から押さえるために、図8で示した本実施例の固定治具を2つ使用する。これにより、スリーブを正確にかつ安定に固定することができるようになる。   In the construction method using the fixing jig according to one embodiment of the present invention, two fixing jigs of this embodiment shown in FIG. 8 are used to hold the sleeve from both sides. As a result, the sleeve can be fixed accurately and stably.
