PURPOSE:To enhance execution efficiency by forming beam sides of precast plates, arranging longitudinal stirrups projected to up and down of the precast plates to up and down slab positions, arranging up and down beams, main reinforcing bars and horizontal stirrups, and placing concrete between the precast plates and concrete of the up and down slabs. CONSTITUTION:Sand 1 and levelling concrete 2 are placed on the ground A of an excavated bottom, and an up and down reinforcing bar 4 as a main reinforcing bar of a mat slab 3 is arranged. After that, level adjusting cradles 5 are provided on the levelling concrete 2, and reinforced concrete precast plates B forming the beam sides are provided on them. Then, a separator 6 is provided between the precast plates B. Haunch sections 7 are projected to both up and down ends of the precast plates B, and longtidudinal stirrups 8 are projected up and down. In addition, the ends of the projected stirrups 8 are bent in a state to arrange them to the slab positions, and bar arrangement 13 of half PC plates 11 and an upper slab 12 is made on the upper haunch section 7 arranging up and down beam main reinforcing bars 9 and horizontal stirrups 10.

リート構造のプレハブ化は多種多様でありプレキャスト
コンクリートの永久型枠を使用することが多いが基礎梁
については鉄筋のプレハブ化が多く提案されている。2. Description of the Related Art There are various types of prefabricated reinforced concrete structures, and a permanent formwork of precast concrete is often used, but many prefabricated reinforcing bars have been proposed for foundation beams.

め仮設用の足場が必要となる。By the way, the construction of the foundation beam requires a considerable amount of work. One of the reasons is that the member cross section is larger than that of the structural member on the ground. Another reason is that the foundation beams are usually located between the double slabs of the mat slab and the upper slab.When removing the beam formwork, a temporary opening for removal is provided in the upper slab and the beam formation is large. A temporary scaffold is required.

【０００４】この発明は前記事情に鑑み、脱型不要な永
久型枠を応用した基礎梁の構築法を開発したものであ
る。In view of the above circumstances, the present invention has developed a method for constructing a foundation beam to which a permanent mold that does not require demolding is applied.

および上下スラブのコンクリートを打設する。When constructing a reinforced concrete foundation beam according to the present invention, the side surfaces of the beam are made of precast plates, and the vertical ribs projecting up and down of the precast plate are arranged at the upper and lower slab positions. And, the upper and lower beam main bars and transverse ribs are arranged, and the concrete between the precast plates and the concrete of the upper and lower slabs are placed.

る。A haunch portion 7 is projectingly provided on the upper and lower ends of the precast plate B, and vertical ribs 8 project vertically. The projecting ribs 8 are bent at the slab position. The half PC board 11 and the reinforcing bar 13 of the upper slab 12 are arranged on the upper haunch part 7 for reinforcing the upper and lower beam main bars 9 and the transverse ribs 10. When pouring concrete, the concrete is poured between the mat slab 3, the precast plate B and the upper slab 12 in this order.

る。As shown in FIG. 2, as a method of further increasing the integration of the post-cast concrete between the pre-cast plates, the inside of the pre-cast plate (post-cast concrete side) can be used.
It is possible to mainly measure shear transmission and integration by making the surface uneven, by projecting the reinforcing bar, or by embedding a part of the reinforcing bar truss in the precast plate.

In addition, the ribs project from the upper and lower ends of the precast plate to ensure the connection between the upper and lower slabs, and the arrangement of the upper and lower slabs is easy. Furthermore, temporary materials such as scaffolds are not required, and construction efficiency is improved.
