DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit type floor covering material to be laid on a balcony, veranda or roof of a house, or on a floor surface such as a tennis court, a poolside, and a changing room.

[0002]

2. Description of the Related Art Conventionally, as a structure for laying floor materials (deck materials) on balconies or verandas of houses, for example, as shown in Japanese Utility Model Publication No. 56-51563, a fixed substrate having a locking groove is conventionally used. A plurality of screws are fixed on the joists, and the ridges on the back side of the long deck material cut to fit the dimensions of the balcony etc. are press-fitted into the locking grooves of each fixed substrate. I was

[0003] Recently, a method of laying a rectangular unit-type floor decorative material on the floor of a balcony or veranda and interconnecting adjacent floor decorative materials has also been adopted. I have. As one of such unit-type floor decorative materials, a plurality of floor-forming materials for forming a drainage space between a floor material main body (made of hard rigid resin) and a surface to be laid are provided on a back surface side having a large number of openings. There is known a floor decoration material of a shiko-type which is integrally formed with legs (for example, Japanese Unexamined Patent Publication No.
7-140402).

[0004]

By the way, floor cosmetics laid on a veranda, a balcony, or the like include a human walking load such as light walking when walking quietly, walking when running around, and a table / chair. Since various loads, such as a load placed on a leg, a support block of a clothes drying die, or an outdoor unit of an air conditioner, are applied, a structure capable of withstanding such loads is required.

[0005] However, the above-mentioned floor-dressing material of the pen type has a large number of openings, and the opening ratio per unit is 30 to 40%. For this reason, when various loads such as the above-mentioned walking load and placing load are applied to the upper surface of the floor decorative material, the load acting portion may be deformed or broken. For example, as shown in FIG. 12, when a load is applied between the legs 102 of the floor decorative material by the legs P of the pipe chair, the member (grid member) 112 of the floor material main body and the reinforcing rib 105 provided thereunder are depressed and deformed. May break or break. The degree of such deformation and breakage of the floor decorative material is particularly high at high temperatures in summer.

[0006] As a countermeasure, it is conceivable to increase the number of legs provided on the back side of the floor material main body. However, most of such floor decorative materials have a product height of 20 mm or less.
If the number of legs increases, water tends to accumulate around the legs due to surface tension after rainfall or watering, and moreover dust tends to accumulate along with the water, which impairs drainage of the ground floor surface A new problem arises.

On the other hand, in consideration of drainage, the height of the product is set at 20.
mm or more, this time the strength of the leg itself becomes a problem,
As a countermeasure, in the current technology, increase the diameter of the legs,
Or there is only a way to increase the number of legs,
Therefore, increasing the product height increases the product weight,
Also, the overall impression (design) of the floor decorative material becomes heavy.

As another countermeasure, a method of increasing the height of the entire reinforcing rib provided on the back side of the flooring body to increase the cross-sectional area of the rib can be considered. Drainage space is narrowed by reinforcing ribs,
The same drainage problem as above occurs, and the rib weight (product weight) also increases.

[0009] The present invention has been made in view of such circumstances, without impairing the drainage on the back side of the flooring body.
It is an object of the present invention to provide a Uonoko-type floor decorative material capable of withstanding various loads such as a walking load and a placing load.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a flooring body having a large number of openings, which is a member which is laid on a floor surface such as a veranda, balcony, rooftop or the like to form a floor. In the decorative flooring material provided with a plurality of legs on the back surface side, reinforcing ribs are provided between two adjacent legs, and the reinforcing ribs extend from the side surface of each leg toward the center between the legs. The rib portion is characterized by being formed into a continuous shape with a fillet portion having a smaller rib height and a chevron portion having a rib height increasing from the fillet portion toward the center between the legs.

[0011] According to the floor decorative material of the present invention, the height of the rib (rib cross-sectional area) at the portion where a large load is applied to walking or a placed object, that is, at the center between the legs and at the base of the leg is increased. Because it is designed to withstand the load applied to each part, even if various loads such as walking load and placing load are applied to the floor decorative material, the load acting part will be depressed and deformed or broken Disappears. In addition, since the rib height is reduced at the portion where the load is not excessively applied, the drainage of the back surface side of the floor material main body is not impaired, and the increase in the rib weight can be reduced.

[0012]

The floor material main body 1 is a molded article of a hard synthetic resin, and has a square outer frame 11 (30 cm square), grid members 12 formed on the outer frame 11 at the same vertical and horizontal pitch, and a square outer frame 11. A member extending in a direction parallel to a diagonal line of the frame 11 and composed of diagonal members 13... 13 passing through the intersection of the lattice member 12, and a plurality of legs 2. These legs 2 are provided below the intersection of the grid members 12, respectively.

The frame 11 of the flooring main body 1 is provided with a plurality of female connecting portions 3 having connecting holes 31 at two sides adjacent to each other at a constant pitch. On each of the opposite sides, a male connecting portion 4... 4 fitted into the connecting hole 31 is provided.
A plurality of units (floor decorative materials) can be connected to each other by using the male / female connecting portions by using the male / female connecting portions.

As shown in FIG. 6, surface ribs 14 parallel to the grid members 12 are provided between the intersections of the diagonal members 13 and the grid members 12, respectively. Openings 10 for drainage are formed between the surface ribs 14, the lattice member 12, and the diagonal member 13.

The surface rib 14 is provided at a position one step lower than the surface of the floor material main body 1. Further, anti-slip projections 15 are provided at positions on the surface of the floor material main body 1 where the grid members 12 intersect.

Next, the features of the present embodiment will be described below.
This will be described with reference to FIGS. FIG. 7 is a partially enlarged rear view of the present embodiment, and FIGS.
It is C sectional drawing and DD sectional drawing.

First, in the present embodiment, the reinforcing ribs 5,... 5, 6, 6.・ 6 are provided.

As shown in FIGS. 8 and 9, each of the reinforcing ribs 5, 6 has a fillet portion 51, whose rib height decreases from the side surface of each leg 2, 2 toward the center between the two legs. 61
And the chevron portions 52, 62 whose rib heights increase from the fillet portions 51, 61 toward the center between the legs are formed in a continuous shape.

Of these reinforcing ribs 5, 6, the reinforcing rib 5 parallel to the outer frame 11 is joined to the lower part of the lattice member 12, and the reinforcing rib 6 along the diagonal direction is joined to the lower part of the diagonal member 13. I have. As shown in FIG. 7, two reinforcing ribs 5 (diagonal reinforcing ribs) provided between four legs 2 adjacent to each other cross each other at a center position between the legs. are doing.

According to the present embodiment having the above structure, as shown in FIG. 10A, the lattice member 12 and the diagonal member 13 between the two legs 2 and 2 of the floor decorative material include: Even when a load is applied by the legs P of the pipe chair, the joints (root portions of the legs 2) between the lattice members 12 and the diagonal members 13 and the legs 2 are reinforced by the fillet portions 51 and 61 of the reinforcing ribs 5 and 6. Therefore, there is no occurrence of depression deformation or breakage including the reinforcing ribs as shown in FIG.

As shown in FIG. 10 (b), even if a load by the leg P of the pipe chair acts on the position above the leg 2 of the floor decorative material, the strength of the leg 2 itself of the floor decorative material is reduced. Since the reinforcing ribs 5 and 6 are reinforced by the fillet portions 51 and 61 (four places), there is no possibility of buckling of the leg 2 of the floor decorative material.

Further, as shown in FIG. 10 (c), a load due to the thin leg P1 is applied to a central position between the two legs 2, 2 of the floor decorative material, and the lattice member 12 and the diagonal member 13 Even if a bending moment acts on the center, the reinforcing ribs 5, 6
The central portion of each of the ribs has a chevron shape and the rib height (rib cross-sectional area) is large.
No depression deformation or breakage including the reinforcing rib of No. 3 occurs.

In the present embodiment, the reinforcing ribs 5 and 6 provided between the legs 2 have a cross-sectional shape, as shown in FIG. The shape may be such that it is reduced (trapezoid), or it may be a rectangular cross section with a constant thickness.

Here, in the present embodiment, as shown in FIG. 6, the surface ribs 14 are provided with the grid members 12 and the diagonal members 13.
Since it is molded at a position one step lower than the upper surface of the, the design is improved as compared with the conventional product.

That is, most of the conventional floor decorative materials having a large number of apertures have almost all of the members on the front side arranged flush with each other. When the floor is constructed by laying on the floor, the entire floor becomes a monotonous design. However, when the floor decorative material of the present embodiment is laid, the light is reduced due to the steps between the lattice members 12 and the diagonal members 13 and the surface ribs 14. When the floor is hit, a shadow appears on the surface of the floor decorative material, and the shadow changes depending on the direction in which the light hits, so that it is possible to construct a floor surface with rich design.

[0028]

As described above, according to the floor decorative material of the present invention, reinforcing ribs are provided between the legs on the back surface side of the floor material main body.
The reinforcing ribs are shaped so that the center position between the legs where a large load is applied and the rib height (rib cross-sectional area) at the base of the leg is large, so it can be used for various loads such as walking load and placing load. It is possible to realize a structure capable of sufficiently withstanding without increasing the number of legs. Moreover, since there is no need to increase the number of legs, the product weight does not need to be heavy, and the amount of resin required for one unit does not need to be large. Flooring materials with good drainage can be provided at low cost.
