Description

【考案の詳細な説明】この考案は、鉄筋コンクリートによるはり、柱
などの構築に際し、アバラ筋、帯筋と主筋とを固
定するための器具に関するものである。[Detailed description of the invention] This invention relates to a device for fixing pulley bars, tie bars, and main bars when constructing beams, columns, etc. using reinforced concrete.

従来、はりの構築に於ては、型枠を組んだの
ち、型枠内で主筋とアバラ筋とを針金で緊縛して
いた。この作業は、型枠内で行われるため、作業
がしにくく、極めて非能率であつた。 Conventionally, in the construction of beams, after a formwork was assembled, the main reinforcement and pulley reinforcements were tied together with wire within the formwork. Since this work was carried out within a formwork, it was difficult and extremely inefficient.

とくに、はりが深く、床から下主筋までの作業
員の手が届かない場合には、一度組立てた型枠の
一部をはずして緊縛作業を行つたのち、再び型枠
を組みなおしたり、予め、主筋とアバラ筋とを固
定しておいて、型枠内に入れるなどしていた。前
者は型枠の取りはずし、再組立てに時間がかか
り、又、後者は組立てた鉄筋が重いので、型枠内
に入れるのに時間がかかるうえ、危険であつた。 In particular, if the beam is deep and workers cannot reach from the floor to the lower main reinforcement, it is necessary to remove part of the assembled formwork and perform binding work, then reassemble the formwork, or The main reinforcement and pulley reinforcement were fixed and placed inside the formwork. In the former case, it took time to remove and reassemble the formwork, and in the latter case, the assembled reinforcing bars were heavy, so it took time to put them into the formwork, and it was dangerous.

そこでこの考案は、ターンバツクルの両ねじ棒
外端部に、先端部に主筋へ係止可能な凹部を有し

付けることを特徴とし、４この係止片を、アバラ
筋を取付けた主筋へ係止して、ターンバツクルを
回転することによつて、主筋とアバラ筋（又は帯
金）とを固定し、主筋とアバラ筋などの組立て作
業を能率的に行うことを目的とする。 Therefore, this invention is characterized in that the outer ends of both threaded rods of the turnbuckle have concave portions at their tips that can be locked to the main reinforcing bars, and two locking pieces that can be opened and closed with each other are attached respectively, and four locking pieces are attached to the outer ends of both threaded rods of the turnbuckle. By locking the retaining piece to the main reinforcement with the stirrup reinforcement attached and rotating the turnbuckle, the main reinforcement and the stirrup reinforcement (or strap) are fixed, making the assembly work of the main reinforcement and stirrup reinforcement more efficient. The purpose is to

以下、図示実施例に基づいて、この考案を詳説
する。 This invention will be explained in detail below based on illustrated embodiments.

１はターンバツクルで、２は本体、３，３はね
じ棒である。両ねじ棒３，３の外端部３′，３′は
偏平に形成される。 1 is a turnbuckle, 2 is a main body, and 3 is a threaded rod. The outer ends 3', 3' of both threaded rods 3, 3 are formed flat.

４，４は一対の板状の係止片で、各々先端部に
は、山がた状の凹部５，５がそれぞれ設けられて
いる。この係止片４，４は、基部を、それぞれ、
両ねじ棒の外端部３′，３′へ、ボルトナツトなど
の締結具６，６によつて、開閉可能に取付けられ
る。 Reference numerals 4 and 4 denote a pair of plate-shaped locking pieces, each of which has a ridge-shaped recess 5, 5 at its tip. These locking pieces 4, 4 each have a base portion
It is attached to the outer ends 3', 3' of both threaded rods by fasteners 6, 6, such as bolts and nuts, so as to be openable and closable.

なお、両ねじ棒の外端部３′，３′に支持片を固
着し、この支持片にそれぞれ係止片を、開閉可能
に取付けてもよい。 Note that support pieces may be fixed to the outer ends 3', 3' of both threaded rods, and locking pieces may be attached to these support pieces so as to be openable and closable.

上述の構成から、第３図に示すように、はりの
型枠７内の４本の主筋８にアバラ筋９を仮に取付
けたのち、ねじ棒外端部３′，３′に取付けた、そ
れぞれ一対の係止片４，４を外開きにして、、各
凹部５を主筋８にそれぞれ係止する。ついで、タ

３を伸長すれば、係止片４は、それぞれ主筋８を
アバラ筋９に押付けて両者を固定するので、その
ままコンクリートを打込めばよい。 From the above structure, as shown in FIG. The pair of locking pieces 4, 4 are opened outward to lock each recess 5 to the main reinforcement 8, respectively. Next, rotate the turnbuckle main body 2 to tighten the double threaded rods 3,
3, the locking pieces 4 press the main reinforcing bars 8 against the pulley bars 9 and fix them both, so concrete can be poured as is.

柱の鉄筋組みの場合には、帯筋を仮に取付けた
主筋に、係止片を係止して固定したのち、型枠を
組み、そのままコンクリートを打込む。 In the case of reinforcing columns, the tie bars are fixed to the main reinforcing bars to which the tie bars have been temporarily attached, and then the formwork is assembled and concrete is poured.

以上述べたように、この考案は、主筋とアバラ
筋（又は帯筋）との固定を、極めて容易に行うこ
とができる。したがつて、従来のように、針金を
用いて、主筋とアバラ筋などとを緊縛する手数が
省けるので、能率的である。しかも、安価に提供
できるため、実用上の効果が大である。 As described above, with this invention, it is possible to extremely easily fix the main reinforcement and the pulley reinforcement (or tie reinforcement). Therefore, it is more efficient because it eliminates the need to bind the main reinforcement and the ribs using wires as in the conventional method. Moreover, since it can be provided at low cost, it has great practical effects.
