（産業上の利用分野）
本発明はHPC工法における逆梁の施工方法に
係るものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for constructing a reverse beam in the HPC construction method.
（従来の技術）
従来はスラブが梁上端に接続しているため、梁

躯体上面に突出するPC半梁に形成し、同半梁上
部と一体にスラブコンクリートを打設していた。(Conventional technology) Conventionally, the slab was connected to the top of the beam, so a part of the reinforcing reinforcing bars embedded in the concrete frame of the beam were formed into a PC half-beam that protruded from the top of the frame, and were integrated with the top of the half-beam. Slab concrete was being poured.
従つて逆梁の施工に際しては前記PC半梁を使
用することができず、現場打ちコンクリートによ
つて梁部を施工していた。 Therefore, when constructing a reverse beam, it was not possible to use the PC half beam, and the beam was constructed using cast-in-place concrete.

によつて、前記問題点を解決するものである。(Means for Solving the Problems) The present invention relates to a method of constructing a reverse beam proposed to solve the above problems, and includes a construction method for a reverse beam that is provided with a cotter portion on the side surface that engages with slab concrete.
After installing the PC beam in a predetermined position, the slab reinforcement is arranged so that its end fits into the cotter section, and then slab concrete is poured so that a part of it is filled into the cotter section. By doing so, the above problem is solved.

ものである。(Function) In the present invention, a PC beam with a cotter section on the side is manufactured in advance, and after the PC beam is delivered to the site and installed at a predetermined position, the slab reinforcing bars already placed inside the PC member are Then, the ends of the slab reinforcements are fitted into the cotter section, and then slab concrete is cast and a part of it is filled into the cotter section, and the PC beam and the slab are integrated through the cotter section. In this way, the reverse beam can be prefabricated.
（実施例） 以下本発明を図示の実施例について説明する。(Example) The present invention will be described below with reference to the illustrated embodiments.
ＡはPC梁で、鉄骨梁１を製作したのち、内側
面下方にスラブに対するコツター部２を残してコ
ンクリート３を打設して製作される。 A is a PC beam, which is manufactured by manufacturing a steel beam 1 and then pouring concrete 3, leaving a bulge 2 for the slab on the lower inside surface.
この際、前記コツター部２の表面にコンクリー
ト硬化遅延剤を塗布して水洗いし、同コツター部
の表面を粗面に形成する。 At this time, a concrete hardening retarder is applied to the surface of the cotter portion 2 and washed with water to form a rough surface of the cotter portion.
図中４は予めPC梁Ａに植設されたスラブ上筋、
５はPC梁Ａの補強筋である。 4 in the figure is the slab upper reinforcement installed in advance on the PC beam A.
5 is the reinforcing bar of PC beam A.

して逆梁の施工を完了する。 The PC beam A, which has been pre-fabricated in a factory or the like and has a cotter portion 2 on the lower side thereof, is carried to the site and erected at a predetermined position, and then the slab reinforcement 6 is inserted with its end into the cotter portion 2. After arranging reinforcement as shown in FIG.
Non-shrinkage mortar or the like is injected between the PC beam A and the slab concrete 7, and the slab and the PC beam A are integrated to complete the construction of the reverse beam.

After arranging the reinforcement so that it fits into the
Slab concrete is poured so that a part of it fills the concrete part, thereby integrally connecting the lower side of the PC beam and the slab, making it possible to construct a reverse beam using the PC beam. It is.
