法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of constructing a reinforced concrete beam using precast beam formwork in reinforced concrete construction.
〔従来の技術］
従来の鉄筋コンクリート粱の構築方法は、まず構築する
梁の形状に合わせてせき板を組み立てる。[Conventional technology] In the conventional method of constructing reinforced concrete beams, first, weir boards are assembled in accordance with the shape of the beam to be constructed.

Furthermore, we installed separators to ensure the spacing between the weir plates.
The beam formwork is constructed by securing it with support such as metal fittings.

As described in Japanese Patent No. 5450, a precast formwork in which a beam formwork and a stirrup are integrated may be used. In this case, the beam form is provided with a bent U-shaped stirrup at the leading end of the image passing through the thick inside of the beam form along the inner surface of the beam form; The bent end portion protrudes from the upper end of the beam formwork, and after the beam formwork is installed in a predetermined position and the beam main reinforcement and the tip of the stirrup are tied together, the concrete is Build the beam by pouring.

使用した構築方法では、現場において、梁主筋にスター
ラップを結束したり、鉄筋とせき板の間にスペーサーを
取り付ける等、上記説明したような作業が必要であるた
め、型枠工事が煩雑になるという問題があった。However, in the conventional construction method using beam formwork that is separate from the stirramp, the above-mentioned work such as tying the stirrup to the main beam reinforcement or installing spacers between the reinforcing bars and the sheathing board is required on site. There was a problem in that the formwork work was complicated because of the need for
また、型枠の中にスターラップが納まらなかったり、型
枠工事中に、鉄筋とせき板の間に設置したスペーサーが
外れて、かぶりが適切でなくなったりすることがあると
いう問題もあった。There were also problems in that the stirrups did not fit into the formwork, and during the formwork construction, spacers installed between the reinforcing bars and the weir boards sometimes came off, resulting in improper covering.
さらに、梁型枠とスターランプが一体になっているプレ

。このため、梁型枠の肉厚が相当厚くなり型枠自体が重
くなるために型枠の取り付は時に大型の揚重機が必要と
なり、街中の小規模建築工事には適用できないという問
題があった。Furthermore, in the case of a construction method that uses precast beam formwork in which the beam formwork and star lamp are integrated, cover can be ensured, but the inner thickness of the beam formwork is only thick enough to ensure cover. In addition, the thickness to hold the stirrup is also required. For this reason, the wall thickness of the beam formwork becomes considerably thicker and the formwork itself becomes heavier, which sometimes requires a large lifting machine to install the formwork, which poses the problem that it cannot be applied to small-scale construction work in urban areas. Ta.

部が梁型枠の上端部より突出しているために、運搬時等
に取扱いが面倒であるという問題もあり、さらに、突出
したスターラップの先端と梁主筋との結束作業を行う必
要があるという問題もあった。In addition, with conventional precast formwork, both ends of the stirrup protrude from the upper end of the beam formwork, making it difficult to handle during transportation. There was also the problem that it was necessary to perform binding work between the beam bars and the beam main reinforcements.
この発明は、梁主筋とスターランプの結束を不要にし、
かつ確実に被りを確保して、軽量の梁型枠を提供するこ
とを目的にしている。This invention eliminates the need to tie beam main reinforcements and star lamps,
The purpose is to provide a lightweight beam formwork with reliable coverage.

内へコンクリートを打設することを特徴としている。In order to solve the above object, the method for constructing a reinforced concrete beam of the present invention includes providing ribs protruding from the inner surface of the beam formwork having a U-shaped cross section, integrally with the beam formwork, and An insertion hole for the end of the cap tie is provided at a position near the upper edge on both sides in the width direction of the formwork, and the U part of the star lamp is disposed along the inner surface of the beam formwork and supported within the rib. Construct a precast beam form, span the camping tie in the width direction of the beam form, insert both ends of the cap ties into the insertion holes, and then pour concrete into the beam form. It is characterized by

る。In the method for constructing a reinforced concrete beam of the present invention, a precast beam form is placed at a predetermined position on site, and the main beam reinforcement is housed below the internal open space of the beam form. In order to ensure the pitch between the upper and lower beam main reinforcements, the beams positioned above are placed in a state in which as many kanzai reinforcements as necessary to support the upper beam main reinforcements are spanned in the width direction of the beam formwork. I can forgive the main plot.

れぞれ挿入穴に挿入しグラウト接着する。Next, instead of binding the upper beam main reinforcement and star lamp, cap ties are strung from above the beam main reinforcement in the width direction of the beam formwork, and both ends of the cap ties are inserted into the respective insertion holes. Insert the grout into the grout.
その後、梁型枠内にコンクリートを打設して、打設コン
クリートとプレキャスト梁型枠が一体になって鉄筋コン
クリート梁を構築する。前記梁型枠の外面は構築した梁
の表面を形成する。After that, concrete is poured into the beam formwork, and the poured concrete and precast beam formwork are integrated to construct a reinforced concrete beam. The outer surface of the beam form forms the surface of the constructed beam.

る必要もない。Here, star lamps are arranged in advance on the inner surface of the beam formwork, and the upper beam main reinforcements are secured with cap ties, so there is no need to tie stirrups to the beam main reinforcements. Also, since the stirrup is supported by ribs that protrude from the inner surface of the beam formwork at an overlapping distance from the outer surface of the beam formwork, a spacer is provided! There is no need to ensure cover.

いためシこ、梁型枠の運搬や設置作業を楽に行える。Furthermore, since the beam formwork becomes part of the constructed beam,
Removing the formwork will only involve dismantling the scaffolding and supports. Furthermore, the beam formwork is lightweight because the wall thickness is thinner than the cover thickness, and the tip of the stirrup does not protrude from the upper end of the beam formwork. Easily transport and install beam formwork.

各部を他の数値とすることができることは勿論である。Here, the beam formwork 1 and the ribs 2 are made of inorganic material. The wall thickness of the beam formwork 1 is approximately 20 mm, and the protruding height of the ribs 2 is 30 mm.
The supporting position of the stirrup 3 is set at a distance of 40 mR from the outer surface of the beam form 1 to ensure an overlap of 40 m. Please note that these numbers are just examples.
Of course, each part can have other numerical values.

に当接させて設置される。For formwork work using a precast beam formwork in which the beam formwork 1 and stirrup 3 are integrated as described above, as shown in Fig. 3, first, scaffolding and supports (not shown) are erected. The beam formwork 1 is fixed between columns (not shown). At this time, the beam formwork 1 is installed with a part of its upper end in contact with the lower part of the floor formwork 6.

As many kanzai reinforcements 9 as are necessary to support the main reinforcements 8 are installed, and the beam main reinforcements 8 are placed on the kanzai reinforcements 9. Both ends of the kanzaisu reinforcement 9 are placed on the beam formwork 1. In this state, the cap tie 4 is attached so as to cover the beam main reinforcement 8 located above, and both ends of the cap tie 4 are
Insert into the insertion holes 2c provided at both ends of the beam formwork 1 in the width direction.
そして、その穴２Ｃにクラウド材を充填して、前記キャ
ップタイ４を梁型枠ｌの上部に固定する。Then, the hole 2C is filled with cloud material and the cap tie 4 is fixed to the upper part of the beam form l.

At this time, the beam formwork 1 is integrated with the poured concrete to form a beam, and the beam formwork 1
The outer surface of forms the surface of the beam.

is arranged, and since the upper beam reinforcement 8 is positioned by the cap tie 4 and the Kanzashi reinforcement 9, the beam main reinforcement 5
, 8, tie the stirrups 3 to the upper and lower beam main reinforcements 5.
There is no need to install a separator to ensure a pitch of 8. Further, the stirrup 3 is provided with ribs 2 which are protruded from the inner surface of the beam formwork 1 at a distance that covers the outer surface of the beam formwork 1.
Since it is supported by
