The above end face 1a of the PC beam 1 is
It is covered with mesh 7 which also serves as a formwork.

In this temporarily held state, concrete is poured for the girder and slab to integrate the girder and the small beam.

である。(Example) Examples of the present invention will be described below with reference to the drawings. A connecting member 2 made of L-shaped steel is provided on the joint end face 1a of the PC beam 1, and this connecting member is fixed to the PC beam by anchor bars 3. The horizontal portion 2a of one piece of the coupling member projects from the end face 1a of the beam and forms the same plane as the upper end of the beam. The horizontal part 2a is the beam steel frame 5 of the girder 4
It can be latched onto the upper flange 5a of the beam, and the end of the small beam can be temporarily secured to the beam steel frame. A bolt hole 2 is provided in the horizontal part 2a to fix it to the flange 5a with a bolt 6.
b is open. Three anchor bars 3 arranged at equal intervals are welded to the vertical part of the other piece of the connecting member 2, and the other ends of the anchor bars are each connected to a PC beam 1.
It is fixed to the lower end reinforcement 7 of. Further, the end face 1a of the PC beam 1 is covered with a mesh 8 except for the part covered with the connecting member 2. This mesh was used as a formwork for the beam end when manufacturing the PC beam 1.
次にPC小梁１の施工法について説明する。 Next, the construction method of the PC beam 1 will be explained.

Align a with the bolt hole provided at a predetermined position on the flange, and fix the position of the PC beam with bolts 6 and nuts 9. After that, reinforcing bars 10 and 11 of the girder
Then, the reinforcing bars 7a of the small beam 1 are arranged, the formwork is constructed, and the concrete of the girder and slab is poured.
