Description

本発明は住宅等小構造物の基礎工事に係るものである。 The present invention relates to foundation work for small structures such as houses.

従来、住宅等小構造物の基礎工事はその手段としてまず床掘り、砕石地業、捨てコンクリート打設、後、型枠組立、配筋（鉄筋組立）、鉄筋スペーサー配置、ベースコンクリート打設となり、その後ベースコンクリートの硬化を待って型枠のばらし、埋め戻しといった方法が一般的に行われている。 Conventionally, the foundation work of small structures such as houses is first digging floors, crushed stone, throwing away concrete, then formwork assembly, reinforcement (rebar assembly), reinforcing bar spacer placement, base concrete placement, After that, after the base concrete is hardened, a method of releasing the formwork and backfilling is generally performed.

基礎工事を従来手順で行う際、特に正確さを要求される捨てコンクリート打設以後の型枠組立、配筋（鉄筋組立）、鉄筋スペーサー配置までの工程の作業手順の改善が強く求められていた。完成後の目視検査も不可能であり、構造物にとって最重要な要素の一つである基礎においては、型枠の組立精度はもちろん、鉄筋の配置も鉄筋スペーサーと共に決められた位置を確実に保持されなければならないのであるが、従来手順では型枠側板や鉄筋及び鉄筋スペーサーを打設された捨てコンクリート上にて設計図通りに組み立てるのは熟練を要する手間と時間のかかるものであった。又、固定されていない鉄筋と鉄筋スペーサーはベースコンクリート打設時にコンクリートの圧力で位置ずれを起こしやすかった。 When carrying out foundation work using conventional procedures, there was a strong demand for improvements in the work procedures of the process from formwork assembly, bar arrangement (reinforcement assembly), and reinforcement spacer arrangement after the placement of discarded concrete, which required accuracy. . Visual inspection after completion is impossible, and on the foundation, which is one of the most important elements for the structure, the assembly accuracy of the formwork as well as the arrangement of the reinforcing bars is securely held in place with the reinforcing bar spacers. However, in the conventional procedure, assembling according to the design drawing on the abandoned concrete on which the formwork side plates, the reinforcing bars and the reinforcing bar spacers are placed is time-consuming and time-consuming. In addition, unfixed reinforcing bars and reinforcing bar spacers were liable to be displaced due to the concrete pressure when placing the base concrete.

本発明は上記従来の課題を解決するためになされたものであり、その一つの目的は、専用の器具の使用により熟練者でなくても正確な型枠の組立や鉄筋及び鉄筋スペーサーの位置決めを短時間に行うことのできる作業手順を提供することである。又、作業性に優れた作業手順により、作業者の熟練の度合に左右されることなく安全性にも優れた基礎工法を提供することである。 The present invention has been made to solve the above-described conventional problems, and one object of the present invention is to accurately assemble a formwork and position a reinforcing bar and a reinforcing bar spacer by using a dedicated instrument, even if it is not an expert. It is to provide a work procedure that can be performed in a short time. Another object of the present invention is to provide a basic construction method that is excellent in safety without depending on the skill level of the worker by the work procedure excellent in workability.

上記課題を解決するために本発明は、鉄筋固定金具１の両端に基礎幅となる垂直面２を設けることにより正確な基礎幅の確保が可能とされ、さらに基礎幅内側及び捨てコンクリート上面の適切な位置に配筋用鉄筋を載置支持するくぼみ３があり、その周囲に鉄筋のロック機構４が構成されている。
In order to solve the above-mentioned problems, the present invention makes it possible to secure an accurate foundation width by providing the vertical surfaces 2 serving as the foundation width at both ends of the reinforcing bar fixing metal 1. There is a recess 3 for placing and supporting the reinforcing bar at a proper position, and a reinforcing bar lock mechanism 4 is formed around the recess 3.

又、鉄筋固定金具１両端垂直面２の外側には型枠側板固定用ガイド５が設けられているが、基礎の設置場所や型枠側板の使用方法次第では片方もしくは両方省略しても良い。 Further, although the formwork side plate fixing guide 5 is provided outside the vertical surfaces 2 at both ends of the rebar fixing metal fitting 1, one or both may be omitted depending on the installation location of the foundation and the method of using the formwork side plate.

本発明の鉄筋固定金具によれば、その鉄筋固定金具両端に設けられた垂直面が基礎幅に形成されており、型枠側板も捨てコンクリート上に配置された鉄筋固定金具の垂直面に押し当てるだけで正確な基礎幅を簡単に実現できる。 According to the reinforcing bar fixing bracket of the present invention, the vertical surfaces provided at both ends of the reinforcing bar fixing bracket are formed in the foundation width, and the formwork side plates are also pressed against the vertical surfaces of the reinforcing bar fixing brackets disposed on the concrete. A simple foundation width can be easily realized.

又、鉄筋固定金具にはその基礎寸法に見合う位置に鉄筋受のくぼみがロック機構と共に形成されたことにより、ベースコンクリートの注入圧力にも位置ずれの発生がない配筋を行うことができる。 In addition, the reinforcing bar fitting is formed with a lock mechanism at a position corresponding to the basic dimensions of the reinforcing bar, so that the bar can be arranged without causing any positional shift even in the injection pressure of the base concrete.

又、鉄筋固定金具両端垂直面外側に設けられた型枠側板固定ガイドにより、従来工法による時間と手間のかかる盛土等による型枠側板の固定と比べて、より正確に早くしかも簡単に実現できる。 Further, the mold side plate fixing guides provided on the outer side of the vertical surfaces of both ends of the reinforcing bar fixing metal can be realized more accurately and quickly than the fixing of the side plate of the mold side by banking or the like which requires time and labor.

以下、添付図面を参照しつつ本発明の鉄筋固定金具について説明する。本発明の鉄筋固定金具は、住宅等小構造物の基礎工事におけるベースコンクリート打設のための型枠及び配筋の組立を行う際に好適な鉄筋固定金具である。図１は本発明の鉄筋固定金具の正面図、図２は平面図である。 Hereinafter, the reinforcing bar fixing bracket of the present invention will be described with reference to the accompanying drawings. The rebar fixing metal fitting of the present invention is a rebar fixing metal fitting suitable for assembling a formwork and bar arrangement for base concrete placement in foundation work for small structures such as houses. FIG. 1 is a front view of a rebar fixing metal fitting according to the present invention, and FIG. 2 is a plan view.

本実施形態では鉄筋固定金具１は図１、図２に示すように両端に基礎幅となる垂直面２を有し、その両端より内側には基礎幅に見合った位置に鉄筋１１を支持するくぼみ３が設けられ、その周囲には鉄筋１１を確実にロックするための突起４が形成されている。 In this embodiment, as shown in FIGS. 1 and 2, the rebar fixing bracket 1 has a vertical surface 2 serving as a base width at both ends, and a recess for supporting the rebar 11 at a position corresponding to the base width inside the both ends. 3, and a protrusion 4 is formed around the reinforcing bar 11 for securely locking the reinforcing bar 11.

又、本実施形態では鉄筋固定金具１の両端垂直面２の外側には型枠側板９の厚みに合わせて側板固定用ガイド５が形成されている。そして捨てコンクリート８との接地面にはアンカーボルト孔６が設けられ、配筋の位置を決め作業を確実に行うことができる。 In the present embodiment, side plate fixing guides 5 are formed on the outer sides of the both end vertical surfaces 2 of the reinforcing bar fixing metal 1 in accordance with the thickness of the formwork side plate 9. An anchor bolt hole 6 is provided on the ground contact surface with the discarded concrete 8, so that the position of the bar arrangement can be determined and the work can be performed reliably.

次に図３から図５を参照しつつ、本発明の鉄筋固定金具１の型枠及び配筋組立における実施形態に係る作用について説明する。図３に示すように、従来の基礎工事の工法ではそれぞれがばらばらの型枠側板９や鉄筋１１、鉄筋スペーサー１０等を床掘りされた狭いスペースでの型枠・配筋の組立作業は熟練を必要とし、時間と手間のかかる作業であった。
Next, with reference to FIG. 3 to FIG. 5, the operation according to the embodiment of the rebar fixing bracket 1 according to the present invention in the formwork and bar arrangement will be described. As shown in FIG. 3, in the conventional foundation construction method, assembling work of formwork and bar arrangement in a narrow space in which the formwork side plate 9, the reinforcing bar 11, the reinforcing bar spacer 10, etc., which are separated from each other, are skillful. It was necessary and time consuming.

そして本実施形態では図４に示すようにアンカー孔を有し基礎幅を設定された鉄筋固定金具１の使用により、型枠側板９と鉄筋１１の位置をベースコンクリートの注入圧力にも耐えて保持することができ、型枠・配筋の組立作業を容易に短時間に行うことができる。図５はその基礎の平面説明図である。 In the present embodiment, as shown in FIG. 4, the position of the formwork side plate 9 and the reinforcing bar 11 is maintained withstand the pouring pressure of the base concrete by using the reinforcing bar fixing metal 1 having an anchor hole and a base width set. Therefore, the assembly work of the formwork and bar arrangement can be easily performed in a short time. FIG. 5 is an explanatory plan view of the foundation.

さらに本実施形態ではベースコンクリート打設、硬化後の型枠側板９の解体作業においても型枠側板９の固定方法が、本発明の鉄筋固定金具１の両端垂直面２の外側に設けられた型枠側板ガイド５への挿入固定のため簡単に解体作業を行うことができる。 Furthermore, in the present embodiment, the mold side plate 9 is fixed on the outside of the both ends vertical surface 2 of the reinforcing bar fixing metal 1 of the present invention in the base concrete placing and disassembling work of the mold side plate 9 after hardening. Since the frame side plate guide 5 is inserted and fixed, the disassembly work can be easily performed.
