A floor slab for a general floor in a multi-story building that has highly rigid columns and large beams, and the small beams are composite small beams made of precast small beam materials and cast-in-place concrete,
In particular, the present invention relates to a method of constructing a floor slab made of cast-in-place concrete or a composite floor slab made of cast-in-place concrete and precast members.

Conventionally, in multi-story buildings where the beams are composite beams made of precast beams and cast-in-place concrete, slabs are placed on top of the formwork with plywood formwork supported from below by a number of posts. A floor slab construction method in which reinforcement is placed, concrete is placed, and after the concrete has cured, the posts are removed and the lifting load is diverted to the concrete floor above, and the slab is constructed sequentially from the bottom to the top. had been adopted.

However, in the above conventional method, a large number of posts remain on the lower floor of the concrete floor slab until the curing period of the concrete floor slab ends, so these posts are used for the subsequent process of equipment construction and the delivery of finishing materials. This was an impediment to the progress of the work, making it difficult to shorten the construction period by conducting equipment piping work and finishing work in advance.
また、ポストは、圧縮材として使用される必要
上、かなりの重量物となつており、コンクリート

ものであつた。 In addition, since the posts are used as compressed materials, they are quite heavy, and require a great deal of effort to lift and repurpose them to the floor where concrete is to be poured.
これらの従来欠点の解消策としては、合成小梁

行う方法が先ず考えられる。 As a solution to these conventional shortcomings, precast small beams for making composite small beams are installed between the girders for multiple floors, and the small beams on the lower floor are connected to the small beams on the upper floor via hanging rods. The method is to suspend the slab, erect temporary support beams between the small beams on the lower floor in this state, lay the formwork for the slab on top of the temporary support beams, and perform slab reinforcement and concrete pouring. I can think of it first.

クリートとの打ち継ぎ面となつている。 However, all of the conventionally known precast beam materials for making synthetic beams are formed in such a shape that the upper end of the stirrup protrudes from the upper surface of the precast concrete portion, and the entire upper surface of the precast concrete portion is It serves as a joint surface with cast-in-place concrete.
従つて、上階の小梁材に下階の小梁材を吊り棒
を介して吊り下げる場合、次の問題が派生するこ
とになる。 Therefore, when suspending a small beam on the lower floor from a small beam on the upper floor via a hanging rod, the following problem arises.

り、施工性が悪くなる。 For example, female-threaded metal inserts are buried near the top and bottom of the small beam, and the upper end of the hanging rod is screwed into the metal insert on the bottom of the small beam on the upper floor. When screwing into the insert metal fittings on the top surface of the small beams on the lower floor and suspending the small beams on the lower floor from the small beams on the upper floor, insert the cast-in-place concrete into the hanging rod part that corresponds to the thickness of the cast-in-place concrete. Some kind of edge cutting work is required, such as wrapping a material around the material to prevent it from adhering to the surface of the material, which impairs workability.

トコンクリート部分が欠損する虞れがある。 In addition, as mentioned above, when insert hardware is buried, the effective cross-sectional area of the precast concrete part is small, and there is a risk that the precast concrete part around the insert hardware may be damaged due to the pull-out force acting on the insert hardware. There is.
