合致させて配設したことに存するものである。In conventional beam rebar assembly work, when fixing the main bars with a hoop, if the main bars cannot be lined up on the top and bottom sides of the hoop, the main bars are placed inside the hoop in multiple stages such as two or three stages. Hang the hoop from the top of the hoop using a binding iron wire so that it can be placed horizontally.
You can maintain the spacing between each main reinforcement by lowering it, or
The main reinforcing bars are bound and held on the left and right sides of the hoop using binding wires.As a result, positioning and fixing the main reinforcing bars is time-consuming.
There are disadvantages such as increased assembly man-hours, and the strength of the beam decreases because the main reinforcement falls off from its designated position due to the pushing with wood chips or stirring, which is done to improve the circulation of concrete during concrete pouring. Therefore, this idea solves the above-mentioned difficulties, improves the strength and toughness of the beam, and creates a spiral tie bar for beams that makes on-site assembly extremely easy, quick and accurate. It was devised for the purpose of providing a continuous spiral band reinforcing bar with a plurality of approximately rectangular hoops of the same outer diameter, and the hoops of the spiral band reinforcing bar are This consists in that main reinforcement mounting rods that project horizontally toward the inside of the opposing vertical members are arranged at every appropriate number of hoop stages and with the attachment positions of the hoops matching each other.
以下、この考案の実施例を図面に基づいて説明する。Hereinafter, embodiments of this invention will be described based on the drawings.
鉄線で連続した複数の同一外径寸法づ路長方形状のフー
プ1になるように螺旋状帯鉄筋2を形成する。A spiral band reinforcing bar 2 is formed so as to form a plurality of continuous rectangular hoops 1 having the same outer diameter using iron wire.
そして、このフープ1の垂直部材1Aの内側夫々に、適
当長の複数本の主筋載置杆3の一端をフープ1相互間で

る。Then, one end of a plurality of main reinforcement mounting rods 3 of an appropriate length is fixed to each of the inner sides of the vertical member 1A of the hoop 1 via fixing parts 1 such as welding, with the mounting positions between the hoops 1 being fixed.
主筋載置杆3は相対峙する一対の垂直部材1A夫々に対
称位置で且つ垂直部材IAに対し直交して水平に、夫々
の対向端面5間に少くとも主筋8の直径より幅広な間隔
6を有するよう取付けられる。The main reinforcement mounting rod 3 is placed at a symmetrical position with respect to each of the pair of vertical members 1A facing each other, and horizontally orthogonally to the vertical member IA, with an interval 6 at least wider than the diameter of the main reinforcement 8 between the opposing end surfaces 5. Installed to have.
尚、主筋載置杆3は杆体をコ字形に折曲してその背部4
を鉄筋2に溶接等で固定し、両脚をフープ1の内方へ突
出させるようにしても良い。In addition, the main reinforcement mounting rod 3 is made by bending the rod body into a U-shape and attaching the back 4
may be fixed to the reinforcing bars 2 by welding or the like, and both legs may protrude inward of the hoop 1.
また、主筋載置杆3の長さは対向するもの同志で異って
いても良く、或いは対向させずに段違いに設けることも
できる。Further, the lengths of the main reinforcing rods 3 may be different between the opposing ones, or they may be provided at different levels without facing each other.
この考案は如上のように構成し、螺旋状帯鉄筋2のフー
プ1の相対峙する垂直部材1A夫々に内側方向に向けて
水平に突出する主筋載置杆3をフープ1適数段毎でかつ
フープ1相互間での取付位置を合致させて配設したから
、フープ1内に主筋8を二段、三段等の複数段で水平に
配設することができるものであり、特に保形性に優れて
いるため、コンクリートを拘束し易く臥梁の強度とじん
性を高めるのに極めて大きな効果がある。This invention is constructed as described above, and main bar mounting rods 3 projecting horizontally inward from each of the facing vertical members 1A of the hoop 1 of the spiral band reinforcing bar 2 are installed at every appropriate number of stages of the hoop 1. Since the hoops 1 are arranged so that their attachment positions match each other, the main reinforcements 8 can be horizontally arranged in multiple stages, such as two or three stages, within the hoop 1, and are particularly effective in shape retention. Because of its excellent properties, it easily binds concrete and is extremely effective in increasing the strength and toughness of girders.
しかも、主筋載置杆3に主筋8を配設し、鉄線や溶接等
で固定するだけであるから、従来のような鉄線等によっ
て主筋8を吊り下げる煩られしい作業がなくなり、フー
プ1内への主筋8の配置が容易で迅速にしかも正確に行
えるものであり、鉄筋組立工事の省力化に著しく役立つ
ものである。Moreover, since the main reinforcement 8 is simply placed on the main reinforcement mounting rod 3 and fixed with iron wire, welding, etc., the troublesome work of suspending the main reinforcement 8 with iron wire, etc., as in the past, is eliminated, and the main reinforcement 8 can be placed inside the hoop 1. The arrangement of the main reinforcing bars 8 can be done easily, quickly and accurately, and is extremely useful for labor saving in reinforcing bar assembly work.

よれば、主筋8はフープ1の垂直部材1Aに水平に固着
された主筋載置杆3に載置されるものであるから、従来
存した主筋の脱落等がなく梁の強度低下を来たすことが
ない。In addition, when suspending 8 main bars using conventional iron wires, etc.,
The main reinforcing bars fixed to the vertical members of the stirrup may fall off due to vibrations during form work or concrete pouring, or vibrations caused by thrusting or stirring with pieces of wood to improve the circulation of the concrete during this pouring. However, according to this invention, the main reinforcement 8 is placed on the main reinforcement mounting rod 3 horizontally fixed to the vertical member 1A of the hoop 1. Therefore, the conventional main reinforcement does not fall off, and the strength of the beam does not deteriorate.
そして、主筋載置杆3の固定部Tをフープ1の外側へ突
出させずに形成したから、コンクリートの覆い厚さを均
一に確保し強度を安定させることができる。Since the fixing part T of the main reinforcement mounting rod 3 is formed without protruding to the outside of the hoop 1, it is possible to ensure a uniform covering thickness of concrete and stabilize the strength.
尚、対向する主筋載置杆3の両端面5の間に少くとも主

しく役立つようになる。In addition, reinforcing bars can be assembled by providing an interval 6 wider than the diameter of the main reinforcement 8 between the opposite end surfaces 5 of the main reinforcement mounting rods 3, or by providing the main reinforcement mounting rods 3 at different levels without facing each other. During construction, it becomes easy to move and adjust the arrangement of the main reinforcing bars 8 within the hoop 1, and it also becomes extremely useful in reducing assembly man-hours.
略矩形状で同一外形のフープ1が複数個連続された螺旋

束具9によって結束し、施工現場への運搬、ストック等
を容易なものとできる。Since the spiral reinforcing steel bar 2 is made up of a plurality of continuous hoops 1 having substantially rectangular shapes and the same external shape, before use it is compressed and tied with suitable binding tools 9, and transported to the construction site, stocked, etc. It can be done easily.
しかも、標準化が可能であるから工場で量産することが
容易であり、廉価な製品を提供できる。Furthermore, since standardization is possible, it is easy to mass-produce at a factory, and inexpensive products can be provided.
加えて、使用の際は結束具9を外して主筋8に挿通して
