Description

本発明は、鉄筋コンクリート造建築物の壁の目地棒に関するものである。   The present invention relates to a joint rod for a wall of a reinforced concrete building.

目地棒は、コンクリート、モルタル構造物の目地形成にしようとするもので、近年、断面台形の発泡合成樹脂製のものと、内部が中空の硬質合成樹脂製のものとが広く実用化され、型枠パネルに上底部から釘打ちなどにより固定して使用するものである。   Joint rods are intended to form joints for concrete and mortar structures. In recent years, trapezoidal cross section made of foam synthetic resin and hollow synthetic resin made of hard synthetic resin have been widely put into practical use. It is used by being fixed to the frame panel by nailing from the upper bottom.

一方、鉄筋鉄骨コンクリート造、鉄筋コンクリート造などの鉄筋コンクリート造建築物の外壁などでは、コンクリートの乾燥収縮により亀裂が発生し、躯体強度の低下を招くおそれがある。そこで、任意の多数箇所に亀裂が発生することを防止するため、コンクリート躯体の所定箇所に予め亀裂誘発部（ノッチや台形目地）を施しておき、この箇所に応力を集中させてひび割れを積極的に起こし、他の箇所に亀裂が発生しないようにしている。   On the other hand, in the outer wall of a reinforced concrete structure such as a reinforced steel concrete structure or a reinforced concrete structure, cracks are generated due to drying shrinkage of the concrete, which may lead to a decrease in the strength of the frame. Therefore, in order to prevent the occurrence of cracks at any number of locations, crack-inducing parts (notches and trapezoid joints) are pre-applied to the specified locations of the concrete frame, and stress is concentrated at these locations to actively crack. To prevent cracks from occurring in other locations.

下記特許文献１はその一例を示し、型枠合板に設置する目地棒として、下底部を型枠合板への接合面とした断面かまぼこ形状の目地棒において、ノッチ形成用の尖頭突起を形成したものである。
特開２００８−０３８５５１号公報 The following Patent Document 1 shows an example of this. As a joint rod to be installed on a mold plywood, a notched protrusion is formed on a joint rod having a cross-section of the bottom bottom portion as a joint surface to the mold plywood. Is.
JP 2008-038551 A

前記特開２００８−０３８５５１号に記載の目地棒は、型枠と接する部分が下底部の全面であり、目地棒の下底部と型枠とは面接触する。そのため、型枠と目地棒の間の密着性が低く、コンクリートのノロがこの間に毛細管現象により入り込んでしまい、その後の施工性が悪くなったり、形成された目地の角部のコンクリートが劣化してしまうなどの不具合が発生していた。   In the joint rod described in Japanese Patent Application Laid-Open No. 2008-038551, the portion in contact with the mold is the entire bottom surface, and the bottom bottom of the joint and the mold are in surface contact. For this reason, the adhesion between the formwork and the joint rod is low, and the concrete nodule enters through the capillarity during this time, resulting in poor workability, and deterioration of the concrete at the corners of the formed joint. There was a problem such as.

本発明は前記従来例の不都合を解消するものとして、型枠と目地棒との接合面の密着度を向上させ、コンクリートのノロが入り込むことを防止して目地の角部のコンクリート劣化などの発生を防ぐことのできる鉄筋コンクリート造建築物の壁の目地棒を提供するものである。   The present invention eliminates the inconvenience of the conventional example, improves the adhesion of the joint surface between the mold and the joint rod, prevents the concrete from entering, and causes the deterioration of the concrete at the corners of the joint. It is intended to provide a joint rod for a wall of a reinforced concrete structure that can prevent the above.

請求項１記載の本発明は、中空の断面台形形状で、底辺を上辺よりも長く形成し、底辺と上辺とをつなぐ左右の辺のいずれかの辺を底辺と上辺に対して直角に位置付けし、他方の辺を上辺から底辺に向けて外側に広がるテーパー面に形成した本体からなる目地棒であり、上辺の一方の角部からノッチ形成用の突起を前記直角に位置付けした辺からその延長上で一体に突設し、上辺と左右の辺のいずれかの辺との角部はアールに形成して円弧上の面取り部に形成し、底辺と上辺とには対向位置に釘打ち孔をそれぞれ設け、底辺の両側の角部と、突起の先端部に軟質部材で形成した突起をそれぞれ設け、底辺の両側の角部に設けた突起は底辺よりも外側に突出して合板型枠との接合部としたことを要旨とするものである。 The present invention according to claim 1 has a hollow cross-sectional trapezoidal shape , the base is formed longer than the upper side, and one of the left and right sides connecting the base and the upper side is positioned perpendicular to the base and the upper side. The other side is a joint rod made of a main body formed in a tapered surface extending outward from the upper side toward the bottom side , and the projection for forming the notch is extended from the side positioned at the right angle from one corner of the upper side. The corners of the upper side and one of the left and right sides are rounded to form a chamfered portion on the arc, and nailing holes are formed at opposite positions on the bottom side and the upper side, respectively. Provided with corners on both sides of the base and projections made of a soft member at the tip of the protrusion, and the protrusions provided on the corners on both sides of the base protrude outside the base and join the plywood formwork The gist of this is

請求項１記載の本発明によれば、目地棒本体と型枠合板との接合箇所には、接合突起が介在するから、この接合突起により目地棒と型枠合板との密着性が良好になり、目地棒と型枠合板との間にコンクリートノロが入りにくくなる。   According to the first aspect of the present invention, since the joint protrusion is interposed at the joint portion between the joint rod body and the mold plywood, the joint protuberance improves the adhesion between the joint rod and the mold plywood. , It becomes difficult for the concrete slot to enter between the joint rod and the formwork plywood.

また、接合突起を軟質部材で形成することにより、型枠合板への密着性をさらに向上できる。 Moreover, the adhesiveness to a formwork plywood can further be improved by forming a joining protrusion with a soft member.

さらに、ノッチ形成用の突起を目地棒本体と一体に形成することにより、目地棒の中にコンクリートノロが入り込むことがない。 Furthermore, by forming the notch forming projections integrally with the joint rod main body, the concrete rod does not enter the joint rod.

以上述べたように本発明の鉄筋コンクリート造構造物の壁の目地棒は、目地棒の型枠との接合部に接合突起を設けたから、目地棒と型枠との間にコンクリートノロが入り込みにくくなり、型枠と目地棒との接合面の密着度を向上させることができ、目地の角部のコンクリート劣化などの発生を防ぐことのできるものである。   As described above, the joint rod of the wall of the reinforced concrete structure according to the present invention is provided with the joint protrusion at the joint portion with the joint rod mold, so that it is difficult for the concrete rod to enter between the joint rod and the mold. It is possible to improve the adhesion of the joint surface between the mold and the joint rod, and to prevent the deterioration of concrete at the corners of the joint.

以下、図面について本発明の実施形態を詳細に説明する。図１は本発明の鉄筋コンクリート造建築物の壁の目地棒の実施形態を示す設置状態の横断平面図、図２は同上目地棒の斜視図で、図中１は本発明の目地棒、４は型枠合板、５は型枠合板４により形成する鉄筋コンクリート造建築物の壁である。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional plan view of an installation state showing an embodiment of a wall joint rod of a reinforced concrete building according to the present invention, FIG. 2 is a perspective view of the joint rod of the same, in which 1 is a joint rod of the present invention, 4 is Formwork plywood 5 is a wall of a reinforced concrete building formed by formwork plywood 4.

このような型枠合板４に設置する目地棒１として、本体２を中空の断面台形形状に形成し、図２において下部の上辺７の一方の角部からノッチ形成用の突起３を一体に突設した。   As a joint rod 1 installed on such a mold plywood 4, a main body 2 is formed in a trapezoidal shape with a hollow cross section, and a notch forming projection 3 is integrally projected from one corner of the upper side 7 in FIG. Set up.

目地棒１は、材質として例えば発泡合成樹脂、硬質合成樹脂などの合成樹脂製、またはゴム製とし、合成樹脂製の場合は押出し成形などにより一体に形成する。   The joint rod 1 is made of, for example, synthetic resin such as foamed synthetic resin or hard synthetic resin, or rubber, and is integrally formed by extrusion molding in the case of synthetic resin.

本体２は、底辺６を上辺７よりも長く形成し、底辺６と上辺７とをつなぐ左右の辺、例えば右辺８を底辺６と上辺７に対して直角に位置付けし、左辺９を上辺７から底辺６に向けて外側に広がるテーパー面に形成する。   The main body 2 is formed such that the base 6 is longer than the upper side 7, the left and right sides connecting the base 6 and the upper side 7, for example, the right side 8 is positioned at right angles to the base 6 and the upper side 7, and the left side 9 is It forms in the taper surface which spreads outside toward the base 6.

これにより前記ノッチ形成用の突起３は右辺８からその延長上で突出することになる。   As a result, the notch forming projection 3 protrudes from the right side 8 on its extension.

上辺７と左辺９との角部はアールに形成して円弧上の面取り部１０に形成することによって該角部に応力集中によるひび割れ発生を防止することができる。   The corners of the upper side 7 and the left side 9 are rounded and formed in the chamfered portion 10 on the arc, thereby preventing cracks due to stress concentration at the corner.

底辺６と上辺７とには対向位置に釘打ち孔１１ａ、１１ｂをそれぞれ設ける。   Nailing holes 11a and 11b are provided in the opposite positions on the bottom side 6 and the top side 7, respectively.

底辺６の両側の角部と、突起３の先端部に例えば軟質塩化ビニルなどの軟らかい材料を使用する突起１２ａ、１２ｂをそれぞれ設ける。底辺６の両側の角部に設けた突起１２ａ、１２ａは底辺６よりも外側に突出し、図１に示すように合板型枠４との接合部となる。   Protrusions 12 a and 12 b using a soft material such as soft vinyl chloride are provided at the corners on both sides of the base 6 and the tip of the protrusion 3, respectively. The protrusions 12a and 12a provided at the corners on both sides of the base 6 protrude outward from the base 6 and serve as joints with the plywood formwork 4 as shown in FIG.

次にかかる目地棒１を使用して鉄筋コンクリート造建築物の壁５のコンクリートに目地を形成する方法を説明する。目地棒１の本体２の底辺６の側を型枠合板４に当て、釘１３を釘打ち孔１１ａ、１１ｂに打ち込んで目地棒１を型枠合板４に固定する。   Next, a method for forming joints in the concrete of the wall 5 of the reinforced concrete building using the joint rod 1 will be described. The bottom 6 side of the main body 2 of the joint rod 1 is applied to the mold plywood 4 and a nail 13 is driven into the nail holes 11 a and 11 b to fix the joint rod 1 to the mold plywood 4.

この場合、目地棒１の型枠合板４への固定は、前記のように目地棒１に釘打ち孔１１ａ、１１ｂを設けて釘打ちにより行うから、型枠合板４のパネル割りとは別に目地位置を自由に決定できる。   In this case, the joint rod 1 is fixed to the mold plywood 4 by nailing by providing the nailing holes 11a and 11b in the joint rod 1 as described above. The position can be determined freely.

目地棒１が型枠合板４に固定された状態では、底辺６に設けた突起１２ａ、１２ａが線接触状態で型枠合板４に接合し、目地棒１は型枠合板４に対して良好に密着する。   In a state where the joint rod 1 is fixed to the mold plywood 4, the protrusions 12 a and 12 a provided on the bottom side 6 are joined to the mold plywood 4 in a line contact state, and the joint rod 1 is excellent with respect to the mold plywood 4. In close contact.

以上のようにして本発明の目地棒１を型枠合板４に設置し、コンクリートを打設して鉄筋コンクリート造建築物の壁５を形成するとき、底辺６に設けた突起１２ａ、１２ｂが型枠合板４に密着するから、目地棒１と型枠合板４との間にコンクリートノロが入り込みにくくなり、目地角部のコンクリートが劣化することを防げる。   As described above, when the joint rod 1 of the present invention is installed on the mold plywood 4 and the concrete is cast to form the wall 5 of the reinforced concrete building, the projections 12a and 12b provided on the bottom 6 are formed into the mold frame. Since it adheres closely to the plywood 4, it becomes difficult for concrete chips to enter between the joint rod 1 and the formwork plywood 4, and it is possible to prevent deterioration of the concrete at the joint corners.

また、ノッチ形成用の突起３と台形の本体２とを一体に形成してあるから、目地棒１の中空内部にコンクリートノロが入り込むことがなく、コンクリートの劣化のおそれがない。   Further, since the projection 3 for forming the notch and the trapezoidal main body 2 are integrally formed, the concrete rod does not enter the hollow interior of the joint rod 1 and there is no risk of deterioration of the concrete.

コンクリートの硬化後、型枠合板４とともに目地棒１を取り除く。このとき、本体２の角部で、ノッチ形成用の突起３を設けていない側の角部には面取り部１０が形成してあるから、目地棒１をコンクリート躯体から抜きやすくなる。そして、目地棒１の再使用が可能となる。   After the concrete is hardened, the joint rod 1 is removed together with the mold plywood 4. At this time, since the chamfered portion 10 is formed at the corner of the main body 2 on the side where the notch forming projection 3 is not provided, the joint rod 1 can be easily pulled out from the concrete frame. Then, the joint rod 1 can be reused.

このようにして壁５から目地棒１を取り除いた形成された目地１４は、図３に示すように本体２の外形形状の台形となり、先端に突起３によるノッチ１５が形成され、ひび割れはこのノッチ１５の部分に集中する。   The joint 14 formed by removing the joint rod 1 from the wall 5 in this way becomes a trapezoid of the outer shape of the main body 2 as shown in FIG. 3, and a notch 15 due to the projection 3 is formed at the tip, and the crack is notched. Concentrate on the 15 part.

目地１４にはシール材１６を充填することができる。   The joint 14 can be filled with a sealing material 16.
