る。When constructing an underground girder with a beam length of 2 m or more, the main rebar,
Assembling the stirrup on-site requires a lot of temporary material and complicated labor. Therefore, a construction method using mesh rebar (Japanese Patent Publication No. 61-14294 construction method) was also developed, but since the beam formation is high, it is better to successively construct pressure-resistant slabs and beams and concrete instead of placing concrete at once. It may be easy and it may be desirable to assemble the rebar following concrete pouring.

Place the reinforcement and the horizontal reinforcement on the concrete, and then place the concrete under the beam upper main reinforcement, place the beam upper main reinforcement on the concrete, and arrange the upper part of the stirrup reinforcement and apply the concrete. This is the construction method for the underground beam to be installed. The details will be described below with reference to the illustrated embodiment.

る。The reinforcing bar cage 1 in which the lower part of the stirrup bar is connected by the horizontal bar and is knitted in a cross-section is disposed on the base 2 made of concrete such as discarded, and the beam lower main reinforcing bar 3a is arranged in the reinforcing bar cage 1 and then the reinforcing bar cage 1 Placing concrete 4a of a slab to be a pressure plate so as to bury lower and lower beam main reinforcing bars 3a,
Next, the side reinforcing bar cage 6 in which the stirrup muscles 6a are connected by the small diameter temporary fixing transverse muscles 5a and the side reinforcing bar cage 7 in which the abdominal muscles 6b are connected by the small diameter temporary fixing longitudinal muscles 5b are overlapped, and are connected by the purse reinforcement muscle 8. Then, the beams are installed in parallel on the concrete 4a, the beam form 9 is installed on the side thereof, and the concrete 4b is placed up to the position of the beam upper main reinforcing bar 3b, and the beam upper main reinforcing bar 3b is placed on the concrete 4b. Are laid out, and the upper slab concrete 4c is placed so that the upper stirrup bars 10 are overlapped and embedded.

経済的な施工を可能とすることができる。The present invention has the above-described configuration, and even if it is an underground girder with a large beam formation, a side reinforcing bar in which the side reinforcing bars are connected to the stirrup reinforcing bars by the temporary transverse reinforcing bars and a side reinforcing bar in which the abdominal muscles are connected to the longitudinal longitudinal reinforcing bars. Since the baskets are piled up and installed, the total weight can be divided and workability is good. In addition, the beam concrete placement is divided into three stages. In the second stage, concrete is placed up to the lower end position of the beam upper main reinforcement, and the beam upper main reinforcement is laid on the concrete. It is possible to simplify the construction without requiring a temporary knitting bar or a T-shaped supporting work to be supported, and to enable economical construction.
