Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、建物の床を形成する際に用いる床構造材に
関するものである。TECHNICAL FIELD The present invention relates to a floor structure material used when forming a floor of a building.
床構造材に配設されるラチス材は打設するコンクリート
から露出しないようにするため、ラチス材を支持材にて
吊り下げ状にして下面から一定間隔をおいて取付けられ

に示されるように、ラチス材の上弦材を、デッキプレー
トに固定した複数本の山形状支持材の頂部の内側に溶接
にて固着して組立てていた。In order to prevent the lattice material disposed on the floor structure material from being exposed from the concrete to be placed, the lattice material is hung from a support material and is attached at a constant interval from the lower surface. As an example of this, as shown, for example, in Japanese Utility Model Publication No. 61-65111, the upper chord material of the lattice material is fixed by welding to the inside of the tops of the plurality of chevron-shaped support materials fixed to the deck plate and assembled. Was there.

に取付けなければならなかった。このため、つなぎ材と
上弦材とが密着せず、施工後の強度が不安定であった。However, when the lattice material and the support material are assembled, both can move freely without being caught, so that their positioning is difficult and workability is deteriorated. In addition, since the lattice material is simply attached by welding from the inside of the top of the support member as described above, the weight of the lattice material is applied to this welded portion, and there is a problem in strength. Furthermore, at the time of construction, when connecting the lattice members, the ends of the two upper chord members are connected through a tie member, but since the upper chord member is attached to the inside of the top of the support member, Had to be attached to the upper chord through the support. For this reason, the tie material and the upper chord material did not adhere to each other, and the strength after construction was unstable.
したがって、この発明の目的は、ラチス材と支持材の位
置決めが容易で、かつ支持強度の大きい床構造材を提供
することである。Therefore, an object of the present invention is to provide a floor structure material in which the lattice material and the supporting material can be easily positioned and which has a large supporting strength.

ッキプレートに固着したものである。The floor structure material of the present invention comprises a plurality of lattice members formed by connecting an upper chord member and a lower chord member with flexural streaks, and a plurality of supports in which a mountain portion having a flat top portion and a flat skirt portion are alternately formed. Member and a deck plate, the flat top of the support member is positioned and fixed in an orthogonal state at the joining corner of the upper chord member of the lattice member and the bending line, and the skirt portion of the support member is fixed to the deck. It is fixed to the plate.

支持材を介することなく直接取付けることができる。According to the configuration of the present invention, the support member and the lattice member can be easily positioned by bringing the flat top portion of the support member into contact with the joining corner portion of the lattice member. Further, since the upper chord member of the lattice material is mounted on the flat top portion of the support member in a mounted state, it has a large supporting strength and is excellent in stability. Furthermore, by installing the upper chord material of the lattice material so that it is located outside the support material, when attaching the connecting material to the upper chord material,
It can be directly attached without using a support material.

部７をデッキプレート８の凸部に溶接にて固着する。The procedure for assembling the floor structural material according to this embodiment will be described. First, the flat top portion of the support member 5 is positioned in the joining corner portion of the upper chord member 2 of the lattice member 1 and the bending streak 4 in an orthogonal state and fixed by welding. At this time, the upper chord member 2 is supported on the flat top portion of the support member 5 in a mounted state, and the lattice member 1 is drooped. Also,
There are a plurality of lattice members 1 and support members 5, and they are arranged so as to intersect at the joining corners. Next, the skirt portion 7 of the support member 5 is fixed to the convex portion of the deck plate 8 by welding.

ることができるので施工後の強度が安定する。FIG. 3 shows an example of using this floor structure material at a construction site. This floor structure material is installed on both sides of the beam 14. That is, the floor structure material is installed by fixing the end portion of the deck plate 8 to the concrete formwork 15 of the beam 14 in a mounted state. In addition, a connecting material 1 to connect the lattice materials 1 and 1
Six are provided. As shown in FIG. 2, the tie member 16 can be fixed to the upper chord member 2 and the lower chord member 3 in a state of being in close contact with each other, so that the strength after construction is stable.

ることができる。このため、施工後の強度が安定する。According to the present invention, the flat top portion of the supporting member is brought into contact with the joining corner portion of the lattice member to position the both members, so that the work is extremely easy and the productivity is improved. You can Further, at this time, since the upper chord member of the lattice material is supported on the flat top portion of the support material in a mounted state, the weight of the lattice material mainly depends on the support material. For this reason, the lattice material has a large supporting strength and excellent stability as compared with the conventional one that supports the lattice material only by welding.
Further, along with this, since the upper chord member is attached so as to be located outside the chevron portion of the support member, when the connecting member is attached to this upper chord member, the upper chord member can be brought into close contact with the connecting member. Therefore, the strength after construction is stable.
