Description

本発明は、鉄筋コンクリート用スペーサに関するものであり、更に詳しくは、コンクリートの打設時に、型枠から所定の間隔を保って鉄筋を保持する鉄筋コンクリート用スペーサに関するものである。   The present invention relates to a reinforced concrete spacer, and more particularly to a reinforced concrete spacer that holds a reinforcing bar at a predetermined distance from a mold when placing concrete.

従来、この種の鉄筋コンクリート用スペーサとしては、図９に示すような構成のものが知られている。この鉄筋コンクリート用スペーサ１は、コンクリート素材で形成したブロック状のスペーサ本体２と、このスペーサ本体２の鉄筋支持面３に設けた取付溝４に嵌め込んだ鉄筋支持具５とから構成される（特許文献１参照）。   Conventionally, as this type of reinforced concrete spacer, one having a structure as shown in FIG. 9 is known. This reinforced concrete spacer 1 is composed of a block-shaped spacer body 2 made of a concrete material and a reinforcing bar support 5 fitted in a mounting groove 4 provided on a reinforcing bar support surface 3 of the spacer body 2 (patent) Reference 1).

鉄筋支持具５は、弾性を有する金属板を略中央位置５ａで左右対称に折り曲げて形成したものであり、前記取付溝４に嵌め込む所定幅のベース部６と、鉄筋を挟着するよう円弧状に湾曲形成した挟着部７と、この挟着部７の先端から上部に向いて拡開したガイド部８とを有する。そして、鉄筋の挿入口９は、鉄筋支持具５の上部に開口した構造である。
特開２００２−４７７６０公報（第１頁、図１及び図３）。 The reinforcing bar support 5 is formed by bending a metal plate having elasticity symmetrically at a substantially central position 5a, and a base portion 6 having a predetermined width to be fitted in the mounting groove 4 and a circle so as to sandwich the reinforcing bar. It has a sandwiching portion 7 that is curved in an arc shape, and a guide portion 8 that widens from the tip of the sandwiching portion 7 toward the top. The reinforcing bar insertion port 9 has a structure opened to the upper part of the reinforcing bar support 5.
JP 2002-47760 A (first page, FIG. 1 and FIG. 3).

この従来例の鉄筋コンクリート用スペーサ１においては、鉄筋支持具５の挿入口９が上部に開口しているので、挿入口９を鉄筋に差し込んで取り付けたあとの作業時に、スペーサ１が自重によって鉄筋から脱落し易いという欠点を有している。   In the reinforced concrete spacer 1 of this conventional example, since the insertion port 9 of the reinforcing bar support 5 is opened at the upper part, the spacer 1 is removed from the rebar by its own weight during work after the insertion port 9 is inserted into the reinforcing bar. It has the disadvantage of being easy to drop off.

また、鉄筋の径よりも大径な挟着部７と、上部に向いて拡開したガイド部８とを有するので、鉄筋支持具５が大型なものとなる。従って、製造コストが割高になるばかりでなく、搬送時や作業時等に鉄筋支持具５をぶつけるなどして変形させ易いという欠点も有している。   Moreover, since it has the pinching part 7 larger in diameter than the diameter of the reinforcing bar and the guide part 8 expanded toward the upper part, the reinforcing bar support 5 becomes large. Therefore, the manufacturing cost is not only expensive, but also has a drawback that it is easily deformed by hitting the reinforcing bar support 5 during transportation or work.

従って、従来例における鉄筋コンクリート用スペーサ１においては、鉄筋に取り付けたあとの作業時に脱落しないようにすることと、鉄筋支持具５が変形しにくいようにすることとに解決しなければならない課題を有している。   Therefore, in the reinforced concrete spacer 1 in the conventional example, there are problems that must be solved to prevent the reinforcing bar 5 from being dropped and to prevent the reinforcing bar support 5 from being deformed easily during the work after being attached to the reinforcing bar. is doing.

前記従来例の課題を解決する具体的手段として本発明は、コンクリート又はモルタルで形成されるスペーサ本体と、該スペーサ本体に取り付けた鉄筋挟持具とからなり、前記スペーサ本体は、上部に略Ｕ字状の鉄筋支持溝を有すると共に、該鉄筋支持溝の縁部近傍に前記鉄筋挟持具を取り付ける取付孔を設け、前記鉄筋挟持具は、前記取付孔に嵌め込む脚部と、該脚部の端部に連設される連結部と、該連結部の端部に連設される板バネ部とを、弾性を有する１枚の金属板を素材にして一体に形成してなり、前記取付孔に前記脚部を嵌め込んで鉄筋挟持具を配設し、前記板バネ部の下部に鉄筋挿入口を設けたことを特徴とする鉄筋コンクリート用スペーサを提供するものである。   As a specific means for solving the problems of the conventional example, the present invention comprises a spacer main body formed of concrete or mortar and a reinforcing bar holding tool attached to the spacer main body, and the spacer main body is substantially U-shaped at the top. And a reinforcing hole for attaching the reinforcing bar holding tool in the vicinity of the edge of the reinforcing bar supporting groove, and the reinforcing bar holding tool includes a leg part fitted into the attaching hole, and an end of the leg part. The connecting portion connected to the connecting portion and the leaf spring portion connected to the end of the connecting portion are integrally formed from a single metal plate having elasticity, and the mounting hole The present invention provides a reinforced concrete spacer, wherein a reinforcing bar holding tool is provided by fitting the leg part, and a reinforcing bar insertion opening is provided at a lower part of the leaf spring part.

また、前記板バネ部の自由端部は、前記スペーサ本体の側面よりも外方向に突出して位置するように形成した構成としたものであり、そして、前記脚部及び板バネ部には、挟持した鉄筋に当接して保持する突起部を複数箇所に形成した構成としたものであり、更に、前記複数箇所の突起部は、挟持した鉄筋への当接位置がそれぞれズレるように形成した構成としたものであり、また、前記脚部には、返し片が形成されている構成としたものである。   Further, the free end portion of the leaf spring portion is formed so as to protrude outward from the side surface of the spacer body, and is sandwiched between the leg portion and the leaf spring portion. A plurality of protrusions that are held in contact with and held by the reinforcing bars, and the protrusions at the plurality of positions are formed so that the positions of contact with the sandwiched reinforcing bars are shifted from each other. Further, the leg portion is configured to have a return piece.

本発明に係る鉄筋コンクリート用スペーサは、コンクリート又はモルタルで形成されるスペーサ本体と、該スペーサ本体に取り付けた鉄筋挟持具とからなり、前記スペーサ本体は、上部に略Ｕ字状の鉄筋支持溝を有すると共に、該鉄筋支持溝の縁部近傍に前記鉄筋挟持具を取り付ける取付孔を設け、前記鉄筋挟持具は、前記取付孔に嵌め込む脚部と、該脚部の端部に連設される連結部と、該連結部の端部に連設される板バネ部とを、弾性を有する１枚の金属板を素材にして一体に形成してなり、前記取付孔に前記脚部を嵌め込んで鉄筋挟持具を配設し、前記板バネ部の下部に鉄筋挿入口を設けたことによって、この鉄筋挿入口がスペーサの横方向に開口することとなる。従って、鉄筋挟持具を鉄筋に取り付けたあとの作業時に、スペーサが鉄筋から脱落しない。
また、鉄筋挟持具が従来例のものと比較してコンパクトに形成されるので、搬送時や作業時等に鉄筋挟持具を変形させにくいという種々の優れた効果を奏する。 The spacer for reinforced concrete according to the present invention includes a spacer main body formed of concrete or mortar and a reinforcing bar holding tool attached to the spacer main body, and the spacer main body has a substantially U-shaped reinforcing bar supporting groove in the upper part. In addition, an attachment hole for attaching the reinforcing bar holding tool is provided in the vicinity of the edge of the reinforcing bar supporting groove, and the reinforcing bar holding tool is connected to the leg part fitted into the attachment hole and connected to the end part of the leg part. And a plate spring portion connected to the end of the connecting portion are integrally formed from a single metal plate having elasticity, and the leg portion is fitted into the mounting hole. By arranging a reinforcing bar holding tool and providing a reinforcing bar insertion port at the lower part of the leaf spring part, the reinforcing bar insertion port opens in the lateral direction of the spacer. Therefore, the spacer does not fall off from the reinforcing bar during work after the reinforcing bar holding tool is attached to the reinforcing bar.
Further, since the reinforcing bar holding tool is formed more compactly than that of the conventional example, various excellent effects can be obtained in that the reinforcing bar holding tool is hardly deformed at the time of transportation or work.

また、板バネ部の自由端部は、前記スペーサ本体の側面よりも外方向に突出して位置するように形成したことによって、鉄筋挿入口を鉄筋に差し込むときに、板バネ部の自由端部がガイドの役目を果たすので、鉄筋への取り付けが容易になるという優れた効果を奏する。   In addition, the free end portion of the leaf spring portion is formed so as to protrude outward from the side surface of the spacer body, so that the free end portion of the leaf spring portion is inserted when the reinforcing bar insertion port is inserted into the reinforcing bar. Since it plays the role of a guide, it has an excellent effect that it can be easily attached to the reinforcing bar.

そして、脚部及び板バネ部には、挟持した鉄筋に当接して保持する突起部を複数箇所に形成したことによって、鉄筋がシッカリと保持されると共に、突起部が回り止めの役目を果たすこととなるという優れた効果を奏する。   The leg and the leaf spring are formed with a plurality of protrusions that abut against and hold the sandwiched reinforcing bars, so that the reinforcing bars are held tightly and the protruding parts serve to prevent rotation. It has an excellent effect of becoming.

更に、複数箇所の突起部は、挟持した鉄筋への当接位置がそれぞれズレるように形成したことによって、鉄筋が複数位置でさらにシッカリと保持されると共に、突起部の回り止めの役目がいっそう向上するという優れた効果を奏する。   In addition, the protrusions at multiple locations are formed so that the positions of contact with the sandwiched reinforcing bars are shifted, so that the reinforcing bars are held more securely at multiple positions and the function of preventing rotation of the protrusions is further improved.

次に、本発明の実施の形態について図面を参照しながら説明する。まず、図１及び図２において、符号１１は鉄筋コンクリート用スペーサを示し、このスペーサ１１は、スペーサ本体１２と、このスペーサ本体１２の上部に取り付けた鉄筋挟持具１３とから構成される。   Next, embodiments of the present invention will be described with reference to the drawings. First, in FIGS. 1 and 2, reference numeral 11 denotes a reinforced concrete spacer. The spacer 11 includes a spacer body 12 and a reinforcing bar holding tool 13 attached to the upper portion of the spacer body 12.

スペーサ本体１２は、コンクリート又はモルタルでブロック状に形成されており、下部には、凸部１４が４脚設けられている。このように凸部１４が設けられることによって、型枠に設置したときに、それぞれの凸部１４の先端部が型枠と点接触するようになっている。   The spacer body 12 is made of concrete or mortar in a block shape, and four protrusions 14 are provided at the lower part. By providing the convex portions 14 in this way, the tip portions of the respective convex portions 14 are in point contact with the mold frame when installed on the mold frame.

また、凸部１４と凸部１４との間には、凹溝１５が形成されている。この凹溝１５は、打設したコンクリートの流れを良好にして、型枠との間にコンクリートの打設ムラが生じないように設けられている。   Further, a concave groove 15 is formed between the convex portion 14 and the convex portion 14. The concave groove 15 is provided so as to improve the flow of the placed concrete so that there is no uneven placement of the concrete between the groove and the mold.

スペーサ本体１２の上部は、略Ｕ字状の鉄筋支持溝１６が設けられており、この鉄筋支持溝１６の両側には、それぞれ肩部１７が設けられている。また、鉄筋支持溝１６の縁部近傍には、図４に示すように、所定深さ及び幅の取付孔１８が形成されており、この取付孔１８には、後述する鉄筋挟持具１３の脚部１９が嵌め込まれている。   A substantially U-shaped reinforcing bar support groove 16 is provided on the upper portion of the spacer body 12, and shoulder portions 17 are provided on both sides of the reinforcing bar support groove 16. Further, as shown in FIG. 4, an attachment hole 18 having a predetermined depth and width is formed in the vicinity of the edge of the reinforcing bar support groove 16, and a leg of a reinforcing bar holding tool 13 to be described later is formed in this attachment hole 18. Part 19 is fitted.

鉄筋挟持具１３は、弾性を有する１枚の金属板を素材にして一体に形成してなり、図３に示すように、脚部１９と、この脚部１９の端部に連設される２本の連結部２０と、この連結部２０の端部に連設される板バネ部２１とを有する。   The reinforcing bar sandwiching tool 13 is integrally formed of a single metal plate having elasticity, and is connected to the leg 19 and the end of the leg 19 as shown in FIG. It has the book connection part 20 and the leaf | plate spring part 21 provided in a row by the edge part of this connection part 20. As shown in FIG.

脚部１９は、前記取付孔１８に嵌り込む所定長さ及び幅に形成されており、その表面には、打ち抜き等の手段によって返し片２２が形成されている。この返し片２２は、抜け止めの役目を果たすこととなり、鉄筋挟持具１３が取付孔１８から抜け落ちない。   The leg portion 19 is formed to have a predetermined length and width to be fitted into the mounting hole 18, and a return piece 22 is formed on the surface thereof by means such as punching. The return piece 22 plays a role of retaining, and the reinforcing bar holding tool 13 does not fall out of the mounting hole 18.

連結部２０は、帯状に形成されると共に、途中に２箇所の湾曲状部２０ａが設けられており、その結果、板バネ部２１が弾性をもって連結されるようになっている。   The connecting portion 20 is formed in a belt shape and is provided with two curved portions 20a in the middle, and as a result, the leaf spring portion 21 is connected with elasticity.

板バネ部２１は、所定の幅及び長さを有しており、その自由端部２１ａは、図４に示すように、スペーサ本体１２の側面１２ａよりも外方向に突出して位置するように形成されている（図４中、寸法Ａ参照）。その結果、後述する鉄筋挿入口２３を鉄筋２４に差し込むときに、自由端部２１ａがガイドの役目を果たすので、鉄筋２４への取り付けが容易になる。   The leaf spring portion 21 has a predetermined width and length, and the free end portion 21a is formed so as to protrude outward from the side surface 12a of the spacer body 12 as shown in FIG.
