Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor structure material used in forming the floor of a building.

[Conventional technology]

In order to prevent the lattice material installed in the floor structure material from being exposed from the concrete being poured, the lattice material was suspended from supporting materials and installed at a certain distance from the bottom surface. As an example of this, for example,
As shown in Publication No. 1, the upper chord of lattice material was assembled by welding to the inside of the tops of a plurality of mountain-shaped supports fixed to a deck plate.

[Problem to be solved by the invention]

However, when assembling the lattice material and the supporting material, there is a problem in that the positioning of the lattice material and the supporting material is difficult because there is no place for them to get caught and they can move freely, resulting in a decrease in work efficiency. Further, as described above, the lattice material is simply attached in a hanging state by welding from the inside of the top of the support material, so the weight of the lattice material is applied to this welded part, which poses a problem in terms of strength. Furthermore, during construction,
When connecting these lattice materials, the ends of the two top chord materials are connected via a connecting material, but since the top chord material is attached inside the top of the supporting material, the connecting material is attached to the upper chord through the supporting material. It had to be attached to the material. For this reason, the connecting material and the upper chord material did not come into close contact with each other, and the strength after construction was unstable. Furthermore, since there was nothing to temporarily place the binding material during the installation of the binding material, the installation work was difficult.

Therefore, an object of the present invention is to provide a floor structure material in which the positioning of the lattice material and the supporting material is easy, the supporting strength is high, and the attachment of the connecting material is easy.

[Means to solve the problem]

The floor structure material of the present invention includes a plurality of lattice members constructed by connecting an upper chord member and a lower chord member with bending bars, and a plurality of support members each having a chevron portion having a flat top portion and a flat base portion alternately formed. comprising a material, a deck plate, and a plurality of L-shaped support plates,
Position and fix the flat top of the support material perpendicularly to the joint corner of the upper chord member and the bending bar of the lattice material, fix the hem of the support material to the deck plate, and fix the bottom surface of the horizontal piece of the L-shaped support plate. The vertical piece of the L-shaped support plate is attached to the end of the lower chord member, with the ends of the horizontal pieces facing outward and the ends of the horizontal pieces facing outward.

[Effect]

According to the configuration of the present invention, the support material and the lattice material can be easily positioned by bringing the flat top portion of the support material into contact with the joining corner of the lattice material. Further, since the upper chord member made of lattice material is attached while being placed on the flat top of the support member, the supporting strength is high and the stability is excellent. moreover,
By installing the upper chord material of the lattice material so as to be located outside the supporting material, even when attaching the connecting material to the upper chord material, it can be directly attached without using the supporting material.

Further, the connecting material to be attached to the upper chord member can be temporarily placed on the flat top of the support member, and the connecting member to be attached to the lower chord member can be temporarily placed and attached to the L-shaped support plate.

Additionally, by providing an L-shaped support plate, it can be stably installed on concrete formwork or steel beams.

〔Example〕

An embodiment of the invention is shown in FIGS. 1 and 2.

This floor structure material is formed from a lattice material 1, a support material 5, a deck plate 8, and an L-shaped support plate 17.

The lattice material 1 is composed of an upper chord member 2, a lower chord member 3, and a bending reinforcement 4 made of reinforcing bars, and the bending reinforcement 4 is fixed by welding between the upper and lower chord members 2.3. Further, reinforcing members 18 are welded to both ends to connect the upper and lower chord members 2 and 3. In this case, the flexural reinforcement 4 may also be welded to the reinforcing material 18.

The support member 5 has a plurality of chevron portions 6 having a flat top portion 25.
and a flat base portion 7 that connects the chevron portion 6.
It consists of

The deck plate 8 is formed by pressing a steel plate to have concave portions and convex portions arranged in parallel so as to correspond to the chevron portions 6 and the skirt portions 7 of the support member 5.

The length of the deck plate 8 in the direction of the uneven portion is the length of the lattice material 1
Form it slightly shorter than the length of.

The L-shaped support plate 17 consists of a horizontal piece 19 and a vertical piece 20. The horizontal piece 19 is provided with a long hole 2I into which a nail can be inserted, and the upper end of the vertical piece 20 is formed with a semicircular receiver part 22 into which the end of the lower chord member 3 is fitted.

The procedure for assembling the floor structure material according to this example will be explained. First, the flat top portion 25 of the support member 5 is positioned perpendicularly to the joining corner of the upper chord member 2 and the bending reinforcement 4 of the lattice member 1, and is fixed by welding. At this time, the upper chord member 2 is supported while being placed on the flat top portion 25 of the support member 5, and the lattice member 1 is in a hanging state. Further, there are a plurality of lattice members 1 and supporting members 5, and they are arranged so as to intersect at the joining corner of the upper chord member 2 and the bending muscle 4. Next, the base portion 7 of the support member 5 is fixed to the convex portion of the deck plate 8 by welding. In addition, the L-shaped support plate 17
is attached to the lattice material 1. That is, with the tip of the horizontal piece 19 facing outward, the receiver formed on the vertical piece 20 is connected to the portion 22.
is attached to the end of the lower chord member 3 from below by welding. At this time, the lower surface of the horizontal piece 19 is set to be approximately at the same level as the lower surface of the deck plate 8.

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. In other words, in the concrete formwork 15 of the beam 14, L
With the horizontal pieces 19 of the shaped support plate 17 placed thereon, nails are driven into the long holes 21 to secure them, and this floor structure material is installed. Additionally, connecting materials 16a and 16b are provided to connect the lattice materials 1 and 1. These connecting materials 16a and 16b are
As shown by imaginary lines in the figure, the upper chord member 2 and the lower chord member 3 can be fixed in close contact with each other, so that the strength after construction is stabilized. Further, the upper connecting material 16a can be temporarily placed on the flat top part 25 of the support material 5, and the lower connecting material 16b can be temporarily placed on the L-shaped support plate 17, making the installation work easier. .

In this embodiment, by providing the long holes 21 in the L-shaped support plate 17, dimensional errors in the lattice material 1 can be absorbed. In addition, when the beam 14 is a steel frame, the L-shaped support plate 17 may be fixed by welding.

〔Effect of the invention〕

According to this invention, the flat top of the support material comes into contact with the joining corner of the upper chord member of the lattice material and the bending muscle, and the positioning of both is performed, so the work is extremely easy. Production efficiency can be improved. Further, at this time, since the upper chord of the lattice material is supported while being placed on the flat top of the support material, the weight of the lattice material is mainly applied to the support material. For this reason, the support strength of the lattice material is higher and the stability is superior compared to the conventional structure in which the lattice material is supported only by welding. Additionally, since the upper chord member is attached to be located outside the chevron-shaped portion of the support member, when attaching the tie member to the upper chord member, the upper chord member can be brought into close contact with the tie member. For this reason,
The strength after construction is stable. Further, the connecting material to be attached to the upper chord member can be temporarily placed on the flat top of the support member, and the connecting member to be attached to the lower chord member can be temporarily placed on the L-shaped support plate, making the attachment work easier. Additionally, by providing an L-shaped support plate, it can be stably installed on concrete formwork or steel beams.
