Soundproof layer.

[0003]

The above-mentioned floor panel has an effect in that the walking sound is reduced or silenced. However, the portion other than the upper surface of the steel sheet has a low rust prevention effect because the surface of the steel sheet is exposed, and deterioration due to rust occurs. Furthermore, in this floor body, a floor is formed by laying a large number of floor bodies, but since the side surfaces of the steel plates of the floor body come into contact with each other, the contact portions between the floor bodies and the floor body are fixed. At the contact portion with the floor frame or the like, rattling and creaking tend to occur. The rattle and squeak generate a squeak sound when walking.

Further, a large number of floor panels are laid to form a floor surface. When the upper surface of the floor panel is used as the surface finish as it is, it is necessary to prevent gaps in the seam of the floor panel from the appearance, and from a functional viewpoint, take measures to prevent rainwater from penetrating to the lower surface and dripping from this seam. is there. Unless such measures are taken, for example, when the floorboard is used in an outer corridor on the second floor where a person walks down, rainwater drops on the person. Further, in the floor panel, a notch and a projection for engagement are formed at an edge of a rubber-like tile provided on the upper surface of the floor, and the notch and the projection are overlapped at the time of laying. Attempts are made to prevent rainwater from seeping through the seams of the floorboard. However, the overlapped portion of the floorboard body may not adhere due to molding errors, mounting errors of the floorboard body to the floor frame, etc., so that rainwater permeates from the seam of the floorboard and drops downward. Become.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a high rust-preventing effect, and to prevent rattling and squeaking in the contact portion between the floor members and the contact portion with the floor frame to which the floor member is fixed. Even if there is rattling or creaking, it is possible to prevent the generation of sound when walking due to them,
An object of the present invention is to provide a floor panel that does not allow rainwater that has permeated between floor panels to drop downward when a large number of floor panels are laid.

The bent portion improves the bending rigidity of the substrate.
As shown in the figure, the short side is also bent inward, and the bent portions 2d,
2e may be provided. It is desirable that the lengths of the bent portions 2b to 2e are the same. In addition, if the thickness of the metal plate 2 is sufficient, the bent portions 2b to 2e need not be formed.

A mounting nut 6 for mounting to a floor frame, which will be described later, is welded to an inner surface of the metal plate 2 surrounded by a bent portion on one surface. The number of the mounting nuts 6 is such that the mounting bolts 16 are screwed together when the mounting nuts are mounted on the floor frame, and also functions as a support portion of the floor panel body 1. The distance is appropriately set in consideration of the deflection against a load or the like depending on the rigidity or the like.

The elastic material coating layer 3 is formed on the entire surface of the substrate 4, and the metal plate 2 is not substantially exposed. That is, the surface of the flat portion 2a of the metal plate 2 and the bent portions 2b to 2e
The back surface of the flat portion 2 a of the metal plate 2 is covered with the covering layer 3. For this reason, the floor panel 1 has a high rust prevention effect.

Further, as shown in FIG. 4, the mounting nut 6 is covered over the tip of the nut, so that the buffering effect with the floor frame is increased and the soundproofing function can be made more complete.

Since the coating layer 3 is formed of an elastic material, the surface of the floor panel 1 is provided with cushioning properties. In particular, the coating layer 3a on the front surface side to be a walking surface
Desirably has a certain thickness. As a result, a comfortable walking feeling can be obtained, and the effect of preventing generation of sounds such as walking sounds can be enhanced. The thickness varies depending on the physical properties of the elastic material used for the coating layer 3,
About 15 mm is preferable. The coating layer 3b on the inner surface side of the metal plate 2 is for preventing the inner surface of the metal plate 2 from being exposed, and may be a thin coating as long as it covers the inner surface of the metal plate 2.

As the elastic material for forming the coating layer 3, various rubber materials and synthetic resin elastomers can be used. For example, synthetic rubber such as urethane rubber, isoprene rubber, butadiene rubber, styrene-butadiene rubber, butyl rubber, and thermoplastic elastomer, or synthetic resin elastomer, and natural rubber such as latex rubber can be suitably used. In particular, moldability, mechanical strength, wear resistance, heat resistance,
Urethane rubber is preferred in terms of weather resistance and the like. Urethane rubber is a rubber-like elastic material obtained by reacting a polyester or polyether polyol with an isocyanate compound. Urethane rubber is divided into polyether urethane rubber and polyester urethane rubber, and used as a coating layer of the floor panel of the present invention, cold resistance, heat resistance,
From the viewpoint of rubber elasticity, polyether urethane rubber is particularly preferred.

The covering layer 3 has two elastic projecting pieces 7, 8 as shown in FIGS. Specifically, the covering layer 3 is provided on almost the entire side surface of one side of the floor panel 1.
The surface-side protruding piece 8 is formed so as to be continuous with the outer surface (the surface of the surface-side coating layer 3a) and to be thinner than the height of the floor panel 1. The entire surface-side protruding piece 8 protrudes outside the floor panel 1 by the same width. Further, the coating layer 3 is provided on substantially the entire side surface of the other side of the floor panel body 1 opposite to the one side, with the upper surface substantially at the same position as the extension of the lower surface of the front-side protruding piece 8 or below. And a rear-side protruding piece 7 formed so as to be formed. It is desirable that the lower surface of the back side protruding piece 7 is continuous with the bottom surface of the coating layer 3 that covers the substrate 4, but may be above the bottom surface of the coating layer. The rear-surface-side protruding pieces 7 protrude outside the floor panel body 1 by the same width as a whole.

As shown in FIG. 8, the front side projecting piece 8
It is formed flush with the surface-side coating layer 3a so that the surface becomes flush when the two floor panels are combined. Also,
A gap is formed between the front projecting piece 8 and the rear projecting piece 7 when both projecting pieces overlap. That is, as shown in the drawing, the front-side projecting piece 8 and the rear-side projecting piece 7 of the floor panel 1 are provided.
Is formed to be thinner than the thickness of the floor panel 1. Also, the front-side projecting piece 8 and the rear-side projecting piece 7
The protrusion widths of the two pieces may not be the same, but it is desirable that both are substantially the same or that the front side protruding piece 8 is longer than the back side protruding piece 7 so that no gap is formed at the seam of the floor panel.

In the floor panel 1, a ridge 5 is formed on the upper surface of the rear-side projecting piece 7 over the entire length. Specifically, a protruding ridge 5 protruding upward is provided at a position slightly inside the end on the upper surface of the back side protruding piece 7, and extends to the entire protruding piece 7. The ridge 5 is formed integrally with the coating layer 3 and has the elasticity of the coating layer 3. As shown in FIG. 8, in the floor panel 1, when the floor panel 1 is superimposed, the position of the contact portion between the ridge 5 and the protruding piece 8 becomes the lower surface of the front-side protruding piece 8, and The position is raised, so that leakage of rainwater from the contact portion can be more reliably prevented. As for the shape of the ridge 5, as shown in FIG. By adopting such a shape, the tip of the ridge 5 can be easily deformed.
The distal end portion is pressed between the two to follow the shape of the contact surface, and prevents a step from being formed between the floor panels. Note that the ridge 5 may be formed not by integral with the coating layer 3 but by fixing a member formed by a separate member on the surface of the projecting piece 7. In this case, a material having higher elasticity than the elastic material forming the coating layer 3 may be used as the high elastic ridge.

It should be noted that the floor panel 1 has a rib-like portion 9 at the lower periphery when viewed from the whole.
Form a mounting portion 9 on the floor frame. It is desirable that the lower surface of the mounting nut 6 is set to be substantially the same without protruding below the lower surface of the mounting portion 9 of the floor panel 1.

FIG. 5 shows a floor panel 1 of another embodiment. The difference between the floor panel 1 of this embodiment and the aforementioned 1 is
The ridge 11 is formed so as to protrude downward at a position slightly inside the end on the lower surface of the front-side protruding piece 8 instead of the rear-side protruding piece 7.

FIG. 6 shows a floor panel 1 of still another embodiment. The floor panel 1 of this embodiment has the same basic configuration as the two floor panels described above. Then, as shown in the figure, the floor panel 1 has a ridge 5 projecting upward at a position slightly inside the end on the upper surface of the back side projecting piece 7, and a front side projecting piece 8
Ridge 11 projecting downward at a position slightly inside the end on the lower surface of the ridge. It is desirable that the two ridges 5 and 11 be provided so that when the protruding piece 7 and the protruding piece 8 are overlapped, they are located in parallel with each other. The ridge 11 can be set inside the ridge 5, or vice versa.

Also, as shown in FIG.
May be provided with an extended portion 2f which is continuous with the bent portion 2b of the metal plate 2 and bent at a predetermined angle. The extension 2f is desirably provided on the entire bent portion 2b, but may be partially provided. Providing the extension 2f improves the stability of mounting on the floor frame.

Next, a method of attaching the floor panel 1 will be described with reference to FIGS. First, a steel material 13 having a U-shaped cross section is bridged at an appropriate interval between a support for forming a balcony, an outer corridor, and the like and a wall side of the building, and attached by welding or bolts. Next, the horizontal members 12a to 12d are fixed between the steel members 13 by welding or bolts, and the floor frame 10 is manufactured. And the horizontal member 1
In 2a to 12d, bolt holes 15 formed in advance or formed after assembling the floor frame are provided so as to correspond to the mounting nuts 6 of the floor panel 1. Then, as shown in FIG.
Is mounted, and the floor panel 1 is fastened to the floor frame 10 using the mounting bolts 16. Note that the mounting nut and the horizontal
A buffer sheet material (for example, a washer made of a soft synthetic resin) is interposed as needed between a and d.

Then, as shown in FIG. 8, the next protruding piece 8 of the next adjacent floor panel is positioned on the back side protruding piece 7 of the floor panel 1 previously fixed. The floor body 1 is placed on a floor frame, and the floor body 1 is tightened by bolts 16. The floor structure is formed by repeatedly performing this work on the number of laid floor boards. The binding between the floor frame and the floor body may be performed each time each floor body is laid,
At the end of the laying, they may be tied together in a lump. By such a construction, the flow path 30 is formed at the connection portion of the floor body 1 on the side of the ridge 5, so that the rainwater that has permeated from the seam 31 of the floor body 1 flows into the flow path 30. The water flows into the flow channel 30 toward the rain gutter 17 by a water gradient.

In the above description, the embodiment in which the mounting nut 6 is fixed to one surface of the metal plate 2 has been described. However, a bracket such as an angle material can be used instead of the nut 6. . In the case of this bracket, the entire board including the bracket may be covered with the elastic material coating layer 3 and fastened to the floor frame 10 with appropriate bolts and nuts.

[0028]

According to the floor panel of the present invention, the substrate is not substantially exposed, and furthermore, it can be mounted on the floor frame from the lower side without penetrating the floor panel, so that high rust prevention can be achieved. Has an effect.

The cushioning effect of the covering layer on the surface side of the floor panel provides a comfortable walking feeling and prevents the generation of sound during walking and transportation of objects and the like. In addition, since the entire surface of the floorboard is covered with the elastic material, rattling and squeaking in the contact portion with the adjacent floorboard and the floor frame are less likely to occur, and even if there is some rattling or squeaking, It is possible to prevent the generation of sounds during walking caused by them.

Further, when a floor is formed by laying a plurality of floor bodies, in the floor body of the present invention, rainwater permeated between the floor bodies is formed by the ridges between the front projecting piece and the rear projecting piece. Prevents dripping downward.
