When constructing underground beams with a length of more than m, there were various problems such as the need for a large amount of temporary materials to construct the reinforcing bars on-site, and the assembling of the reinforcing bars requiring a lot of time and effort. Therefore, there is a construction method that uses prefabricated mesh reinforcing bars and uses the rigidity of the free standing mesh reinforcing bars to hold each reinforcing bar, for example, in Japanese Patent Publication No. 61-14294,
This method is disclosed in Japanese Patent No. 1-14295 and the like.

経済的でもある。By the way, underground beams with a large beam size are connected to the reinforced concrete slab at their upper and lower ends, and it is difficult to manage the construction process by pouring concrete on underground beams with a large beam size all at once. It is often desirable to separate the pouring of concrete. Therefore, by assembling the beam reinforcing bars in accordance with the pouring of concrete and gradually hardening the concrete during construction, less temporary materials are needed, construction efficiency is high, and it is also economical.

筋コンクリート地中梁およびスラブの施工法である。This invention involves arranging mesh reinforcing bars with a U-shaped cross section on a foundation, arranging lower main reinforcing bars inside the mesh reinforcing bars, and then placing lower slab concrete to bury the lower part of the mesh reinforcing bars and the lower main reinforcing bars. Next, install the reinforcing bars on the lower slab concrete, arrange the upper main reinforcing bars on the arm rods at the top of the columns, assemble the scrap bars, abdominal bars, and stop bars, install the side formwork, and then install the upper slab concrete. This method of constructing reinforced concrete underground beams and slabs involves pouring concrete beams to the bottom, then installing slab formwork, arranging slab reinforcing bars, and pouring the upper slab concrete.

Established on concrete and connected to mesh reinforcement 1,
Furthermore, the abdominal reinforcement 6 and the stop reinforcement 7 are assembled on the scrap reinforcements 5a and 5b, the side formwork 8 is installed on their sides, and the connecting fittings are assembled, and then the beam concrete 9 is extended to the bottom of the upper slab.
Then, a slab formwork 10 made of a thin concrete plate or the like is installed, slab reinforcing bars 11 are arranged, and an upper slab concrete 3b is placed. In addition, the upper and lower main reinforcing bars 2a,
2b may be arranged in two or more stages.
