Description
本発明の角型螺旋箍成形装置及びその成形方法は、有効的に角型螺旋箍を形成する生産装置に関する。 The square spiral wrinkle forming apparatus and the forming method thereof according to the present invention relate to a production apparatus that effectively forms a square spiral wrinkle.
各種建築物構造に対するに強度の向上要求に伴い、螺旋鉄筋で組成される骨組みにて提供する設計強度は、既に工程業界の機構設計において重視されてある。従って、主鉄筋と組合せて使用される連続螺旋体の彎曲螺旋鉄筋であって、螺旋状筋箍と称される鉄筋箍は、主鉄筋の位置固定と、シャーリングストレングス (せん断耐力) 効力を具える。螺旋鉄筋の断面形状は、設計の必要性に基づいて調整が行なえるも、
通常形状は丸型及び角型であり、梁及び柱の結構体としての箍筋に使用する外、 大型または特殊設計の梁・柱結構体においても、螺旋鉄筋は骨組主体或いは鉄骨とに配合して用いられ、プレキャスト結構体においては、特に螺旋鉄筋を大量に応用してある。
With the demand for improving the strength of various building structures, the design strength provided by the framework composed of spiral reinforcing bars has already been emphasized in the mechanical design of the process industry. Therefore, a continuous spiral bent spiral reinforcing bar used in combination with the main reinforcing bar, which is called a helical reinforcing bar, has a position fixing of the main reinforcing bar and a shearing strength (shear strength) effect. The cross-sectional shape of the spiral rebar can be adjusted based on the design needs.
In general, round and square shapes are used for the reinforcing bar as the structure of the beam and column, and also in large and specially designed beam and column structures, the helical rebar is mixed with the main frame or steel frame. In the precast structure, spiral rebar is applied in large quantities.
典型的な螺旋鉄筋の製造方式は、鉄筋彎曲具を用い、直線状の鉄筋を逐次彎曲して無間隙螺旋輪を形成して当該螺旋輪の首尾を冶具で引き伸ばして間隙を生成する。然し、この生産方式の効率及び間隙制御には改善の余地がある。尚、螺旋鉄筋を用いて骨組み主体とする設計結構体において、人手での束ね、又はスポット・ウェルジングにより螺旋鉄筋側辺に溶接筋を設置した螺旋状の駕篭を形成する方式は、数多な手間と時間を費やす故、螺旋鉄筋需用量が日増しに増加する現状では、経済上の効率向上及び利益の獲得条件を満たすことができない。 A typical method for manufacturing a spiral reinforcing bar uses a reinforcing bar bending tool to form a gap-free spiral ring by successively bending a linear reinforcing bar, and stretching the spiral ring with a jig to generate a gap. However, there is room for improvement in the efficiency and gap control of this production system. There are a number of methods for forming a spiral rod with a welded bar on the side of the spiral reinforcing bar by hand bundling or spot welding in a design structure that uses a helical reinforcing bar as a main frame. Due to the time and effort required, the current situation in which the demand for spiral reinforcing bars increases day by day cannot satisfy the economic efficiency improvement and profit acquisition conditions.
拠って、本発明における主要目的は、有効的に角型螺旋箍を製造するができる角型螺旋箍成形装置を提供することである。 Accordingly, a main object of the present invention is to provide a square spiral wrinkle forming apparatus that can effectively produce a square spiral wrinkle.
尚、本発明の又の目的は、角型螺旋箍成形装置の提供により、従来の直線鉄筋を逐次彎曲して無間隙鉄筋輪を形成した後での鉄筋輪首尾を冶具で引っ張ることによるピッチ生成の作業方式を改善することである。 Another object of the present invention is to provide a square spiral rivet forming device, and to generate a pitch by pulling a rebar ring tail with a jig after bending a conventional straight rebar successively to form a gapless rebar ring. Is to improve the working method.
又、発明に於ける更の目的は、角型螺旋箍成形装置の提供によった時間、手間、原価等の節減リメットによる生産力向上と原価の低減達成である。
（作用）
A further object of the present invention is to improve productivity and reduce costs by providing time-saving, labor, and cost-saving remedies by providing a square spiral wrinkle forming apparatus.

図3a〜3eは、本発明の角型螺旋箍成形装置における中心回転部の局部拡大図と、本発明の角型螺旋箍成形装置200の鉄筋彎曲装置400が、第1の回転部210の軸方向推移に合わせて逐次鉄筋500を各軸方向鉄筋纏部233に係合させて螺旋鉄筋箍100を形成する作動図である。然し、鉄筋彎曲装置400は前記中心回転部230の鉄筋投入側232に設置して位置きめ部411及び鉄筋圧制部420とを含有し、前記鉄筋圧制部420は、鉄筋投入側232の上方において、前記鉄筋投入側232と対向させて設置し、且つ、垂直との定角を挟持しながら角度推移可能に設けて鉄筋500を圧制する。従って、前記中心回転部230が時計の逆回転方向に転動する場合は、前記鉄筋圧制部420を前記鉄筋投入側232下方に対向させて設置し、一定角度に沿って上向きに鉄筋500を圧制することも可である。 FIGS. 3a to 3e are local enlarged views of the central rotating portion in the rectangular spiral wrinkle forming device of the present invention, and the reinforcing bar bending device 400 of the square helical wrinkle forming device 200 of the present invention is the shaft of the first rotating portion 210. FIG. 10 is an operation diagram for forming a spiral reinforcing bar rod 100 by sequentially engaging a reinforcing bar 500 with each axial direction reinforcing bar 233 in accordance with the direction transition. However, the reinforcing bar bending device 400 is installed on the reinforcing bar insertion side 232 of the central rotating part 230 and includes a positioning part 411 and a reinforcing bar suppression part 420, and the reinforcing bar suppression part 420 is located above the reinforcing bar input side 232. The rebar 500 is placed so as to be opposed to the rebar insertion side 232, and is provided so that the angle can be changed while sandwiching a constant angle with the vertical, thereby suppressing the rebar 500. Accordingly, when the central rotating part 230 rolls in the counterclockwise direction of the watch, the reinforcing bar control part 420 is installed facing the lower side of the reinforcing bar insertion side 232, and the reinforcing bar 500 is pressed upward along a certain angle. It is also possible to do.
又、鉄筋500が前記鉄筋投入側232から前記中心回転部230へ送入され、鉄筋500を前記位置きめ部410に挟持させ、鉄筋圧制部420が前記位置きめ部410に対向して移動すれば、鉄筋500に彎曲部510を形成する。従って、鉄筋500が前記鉄筋圧制部420の圧制によって、彎曲を生成すれば、前記第1推進部810ペース部に連結されたリフトアップが同調作動により、下側に推移して鉄筋500の彎曲度過大が避けられる。又、前記位置きめ部410に伸縮上部411及びベース412を有して鉄筋500を挟持する。尚、前記鉄筋圧制部420において鉄筋500を圧制して彎曲部510を形成すれば、伸縮上部411が上方に収縮するとともに、前記ベース412が内向きに摺動して、前記彎曲部510を釈放する。この時点では中心回転部230が未転動であり、上方に纏わって設置された前記軸方向鉄筋纏部233も、元来位置の第1、2、3、4号を維持する。尚且つ、前記ベース412の内向き摺動と共に、前記彎曲部510が釈放される故、彎曲部510は前記中心回転部230の回転作動によって前記軸方向鉄筋纏部233と係合する。この場合、前記中心回転部230に纏って設置された前記軸方向鉄筋纏部233が第4、1、2、3号の位置迄に回転される。 Further, if the reinforcing bar 500 is fed from the reinforcing bar insertion side 232 to the central rotating part 230, the reinforcing bar 500 is clamped by the positioning part 410, and the reinforcing bar control part 420 moves to face the positioning part 410. The bent portion 510 is formed in the reinforcing bar 500. Accordingly, if the reinforcing bar 500 generates a curve by the repression of the reinforcing bar control part 420, the lift-up connected to the first propulsion part 810 pace part shifts downward due to the synchronous operation, and the bending degree of the reinforcing bar 500 Oversize can be avoided. In addition, the reinforcing portion 500 is sandwiched between the positioning portion 410 having a telescopic upper portion 411 and a base 412. If the rebar 500 is pressed to form the bent portion 510 in the rebar control portion 420, the telescopic upper portion 411 contracts upward and the base 412 slides inward to release the bent portion 510. To do. At this time, the central rotating portion 230 has not yet been rolled, and the axial rebar summary portion 233 that is installed in an upward direction also maintains the original positions Nos. 1, 2, 3, and 4. Further, since the bent portion 510 is released along with the inward sliding of the base 412, the bent portion 510 is engaged with the axial rebar bundle portion 233 by the rotation operation of the central rotating portion 230. In this case, the axial rebar bundle portion 233 installed together with the central rotation portion 230 is rotated to the positions of Nos. 4, 1, 2, and 3.
図4a〜4dにおいて、角型螺旋箍成形装置に生成された角型螺旋箍の取外し状態を示す。角型螺旋箍100成形後、前記中心回転部230の十字型溝部231に挟持された軸方向鉄筋纏部233は、軸方向に沿って移動して、前記第1の回転部210の十字型溝部211と、第２の回転部220の十字型溝部221とに挟持された軸方向鉄筋纏部233が徑方向に沿って同調推移することにより、角型螺旋箍100が弛められ、前記軸方向鉄筋纏部233の徑方向に沿った同調推移によって弛められた前記角型螺旋箍100は、前記第1の回転部210が前記中心回転部230からの遠離により、前記軸方向鉄筋纏部233と分離すると共に、第2の回転部220が前記軸方向鉄筋纏部233を挟持して前記中心回転部230から離れた角型螺旋箍100を取外す。又、角型螺旋箍成形装置200には、リフトアップ240を具えて前記角型螺旋箍100の搭載に供され、前記角型螺旋箍100は、前記軸方向鉄筋纏部233から脱離して取外され、上昇したリフトアップ240に角型螺旋箍100を乗せる。 4a to 4d show a removed state of the square spiral rod generated in the square spiral rod forming apparatus. After forming the square spiral rod 100, the axial rebar bundle portion 233 sandwiched by the cross-shaped groove portion 231 of the central rotating portion 230 moves along the axial direction, and the cross-shaped groove portion of the first rotating portion 210 is moved. 211 and the axial rebar gathering portion 233 sandwiched between the cross-shaped groove portion 221 of the second rotating portion 220 tuned along the heel direction, so that the square spiral ridge 100 is loosened, and the axial direction The rectangular spiral rod 100 loosened by the synchronous transition along the heel direction of the reinforcing bar 233 has the axial rebar lining portion 233 when the first rotating part 210 is separated from the central rotating part 230. And the second rotating part 220 detaches the square spiral rod 100 away from the central rotating part 230 with the axial reinforcing bar 233 sandwiched therebetween. Further, the square spiral rod forming apparatus 200 is provided with a lift-up 240 for mounting the square spiral rod 100, and the square spiral rod 100 is detached from the axial rebar bundle portion 233. Remove and place the square spiral rod 100 on the lifted up 240.

The plurality of axial rebar bundle portions are collectively installed around the central rotating portion. It should be noted that bending the reinforcing bar with the reinforcing bar bending device at a specific position of the step 920 to form the bent portion is to separate the axial rebar wrapping portion from the central rotating portion by using the propulsion device, and to sequentially perform the bending device.
