A permeable flooring 10 for a roof balcony (hereinafter also referred to as a permeable flooring 10) according to an embodiment of the present invention shown in FIGS. 1 to 4 is a porous ceramic plate 21 (hereinafter simply referred to as a ceramic plate). 21) is attached to a semi-rigid resin base member 30 (hereinafter simply referred to as base member 30). As shown in FIGS.
The required number is laid on the base floor surface 50a (waterproof sheet in this example). In FIG. 1, the same symbols as those in FIG. 9 described in the section of the related art represent the same members.

The ceramic plate 21 is made of a porous ceramic plate having fine communication holes, and has one surface serving as a joint surface 22 with the base material 30. The ceramic plate 21 has water permeability provided by the fine communication holes, and is manufactured by binding ceramic particles.
The surface of No. 1 becomes rough, is hard to slip even when wet with water, and has good walking properties. Further, since the ceramic plate 21 is made of an inorganic material, it does not corrode and has high durability.

The ceramic plate 21 is preferably formed from a crushed ceramic such as a waste tile or a bowl as follows. That is, the particles of the ceramic crushed material and the vitreous particles obtained by pulverizing waste plate glass or bottles are mixed, water glass is added to the mixed particles, and the mixture is kneaded to prepare a molding material having plasticity. Is put into a mold, pressed and formed into a plate, and the plate is fired. In the ceramic plate 21 thus formed, the vitreous material is melted and solidified by the above-mentioned firing, and the ground ceramic particles are combined to form fine communication holes between the particles. In addition, by coloring the molding raw material, the ceramic plate 21 can have a desired color.

The base member 30 constitutes the lower surface of the permeable floor member 10, is made of semi-hard resin, and is formed into a plate of a required size by extrusion or the like. As the semi-rigid resin, a resin having a tensile modulus in the range of 70 to 700 MPa according to ASTM D-883 is used, and a semi-rigid vinyl chloride resin is suitable. The material is not limited to the above, and other synthetic resins and synthetic rubbers may be used as long as they do not damage or deteriorate the waterproof sheet and the base material itself has weather resistance and durability.

The size of the base member 30 is set such that a required number of the ceramic plates 21 can be arranged in consideration of workability. In this example, the thickness is 5 mm and the width is 150 m
On the upper surface of the base material 30 having a length of 600 mm and a length of 600 mm, four ceramic plates 21 of 148 mm in length and 20 mm in thickness are provided.
They are fixed in a line at an interval of mm with an adhesive. The interval between the ceramic plates 21 constitutes the joint 13 of the permeable floor material 10,
It improves drainage.

The bonding between the ceramic plate 21 and the base member 30 is performed by bonding the base member 3 on the joint surface 22 on the back side of the ceramic plate 21.
This is performed on the entire contact surface with zero. Since the entire surface of the abutment surface is adhered in this manner, the ceramic plate 21 and the base material 30 are tightly fixed without any gap. When the surface of the ceramic plate 21 receives an excessive impact, the impact is directly applied to the rear side. And the shock is efficiently absorbed by the base material 30, and the breakage of the ceramic plate 21 can be efficiently prevented. In addition, since the ceramic plate 21 can be prevented from being damaged even if its thickness is reduced, the entire permeable flooring 10 can be reduced in weight, and the construction work can be facilitated and the permeable flooring 10 can be easily cut. Can be reduced, and the material cost of the permeable flooring 10 can be reduced.

Further, the position of the ceramic plate 21 with respect to the base member 30 is set at the opposite small face (16) of the permeable floor member 10.
a, 17a), one side 16a, 16 of (16b, 17b)
In b, the required amount of the ceramic plate 21 protrudes from the corresponding fore-edge surface 31 of the base material 30, and on the opposite sides 17a and 17b, the required amount of the ceramic plate 21 is retracted from the fore-edge surface 31 of the base material 30. It has become something. Reference numeral 18 is a protruding portion, and 19 is a retreat portion.

Further, in the permeable flooring 10 of the present invention, as can be seen from FIG. 5 showing a cross section 5-5 in FIG. 1 and FIG. A notch 35 is provided on the upper side of the fore-edge surface 31 on one side of the base material 30 which is the back side of the portion 18. That is, since the ceramic plate 21 and the base member 30 are bonded to each other with an adhesive therebetween over the entire contact surface, the adhesive may be slightly extruded at the time of pressing. This notch 35
Holds the excess adhesive B1 extruded from between the ceramic plate 21 and the base member 30 on the back side of the ceramic plate 21 at the protruding portion 18 and
1 is to prevent the surplus adhesive B1 from leaking like burrs. The notch 35 of this example has a cross-sectional shape of 2 m.
Although it has a square shape of m squares, the shape is not limited to this, and may have an appropriate shape and dimensions such as a rectangle, a triangle, and an arc. The adhesive B2 extruded on the fore-edge surface of the ceramic plate at the receding portion has the joint as its joint, so that there is no particular problem even if it is left as it is.

A required number of the permeable floor members 10 are laid on the base floor 50a of the balcony 50,
That is, the semi-rigid resin base material 30 is attached and fixed to the base floor surface 50a by the double-sided adhesive tape T attached to the back surface. It is preferable that the double-sided adhesive tape T be partially adhered to the back surface of the water-permeable floor material 10 so that the water-permeable floor material 10 can be easily replaced with the base floor surface 50a. In this example, a total of six double-sided pressure-sensitive adhesive tapes 2 each having a size of 2 cm × 3 cm were provided at both ends in the longitudinal direction of the back surface of the water-permeable floor material 10 and at intermediate positions thereof. By using the double-sided adhesive tape, if the water-permeable floor material is loose due to unevenness of the base floor surface 50a, it can be easily corrected by overlapping the double-sided adhesive tape. The thickness of the double-sided adhesive tape is preferably about 1 mm.

When the permeable floor material 10 is laid, as shown in FIGS. 5 and 6, between the adjacent permeable floor materials 10A and 10B, the protruding portion 18 of one permeable floor material 10A is connected to the other permeable floor material. It is made to overlap with the retreat part 19 of 10B. As a result, the adjacent permeable floor members become successively heavy, so that the permeable floor members can be reliably fixed. Further, the plurality of permeable floor materials 10 laid on the base floor surface 50a have unity, so that not only the walkability is improved, but also the permeable floor material 10 is lifted and lifted by the negative pressure of the floor surface in a strong wind. Also, warpage due to long-term use can be prevented.

In particular, as described above, the excess adhesive B1 is accommodated in the notch 35 formed on the upper side of the fore-edge surface 31 of the semi-rigid tree base material 30 on the back side of the protruding portion 18 of the ceramic plate 21 and the fore-edge is provided. Since the surplus adhesive B1 does not protrude from the surface 31 in a burr-like manner, the surplus adhesive B1 does not cause a variation in joint width between the water-permeable floor materials 10A and 10B, and does not cause a step or a gap. Face can be obtained. Further, when the permeable floor material 10 is constructed, the edge 31 of the resin base material 30 on the back side of the protruding portion 18 is set so as to contact the edge 31 of the resin base material of the receding portion 19, so that the adjacent permeable floor is formed. The spacing of the joints 13 between the ceramic plates 21 between the materials 10 can be always constant, and combined with the notch effect, it can be laid easily and accurately at a predetermined position, thereby improving the workability and the appearance. In this example, the projecting dimension is 4 mm, the receding dimension is 2 mm, and the difference of 2 mm is the joint 1
It has three widths. These dimensions may be appropriately determined in consideration of designability, material strength, and the like. In addition, it is conceivable to wipe off the excess adhesive B1 without providing the notch 35, but the wiping operation is complicated, and it is very difficult to wipe off the highly adhesive adhesive. However, there remains a problem that the surface of the permeable flooring 10 is easily stained.

In the laying structure, it is preferable that the side of the retreating portion 19 of the ceramic plate 21 is on the side of the drain groove 52 due to the water gradient of the base floor 50a of the roof balcony 50. In this way, as shown in FIG. 7, the edge of the semi-rigid resin base material 30 abuts on the drain groove side wall surface 52a in the water permeable floor material 110 covering the upper surface of the drain groove 52 which is the end of the roof balcony 50. Therefore, the gap between the drain groove side wall surface 52a and the permeable floor material 10 can be more reliably prevented. Moreover,
The abutting portion of the drain groove side wall surface 52a and the edge of the semi-rigid resin base material 30 is provided with a drainer 56 as a cover body at the upper portion of the side wall surface in order to improve the appearance. The material 10 can be prevented from being lifted or lifted. Symbol 5 in the figure
Reference numeral 7 denotes a frame for the permeable floor material 110 laid on the drain groove 52. Although the projecting portion 18 and the retreating portion 19 in this embodiment are formed on two sets of opposed forefaces of the permeable flooring 10, they may be formed on one set of opposed forefaces.

Further, as shown in FIG. 8, a cut-out portion 240 is formed on at least one side of the ceramic plate 210 for the permeable floor member 110 laid on the drain groove 52, and the semi-hard resin base member is formed. The cutout portion 24 is provided at 300.
It is preferable that a notch 330 corresponding to the notch 240 is formed in a portion where 0 is arranged. By doing so, the water that has fallen on the permeable flooring 10 due to rainwater or water sprinkling can be transferred from the permeable flooring 10 to the roof balcony 5 by the water gradient set on the roof balcony 50.
0, and the cutouts 240 and 33 of the permeable floor material 110 disposed above the drainage groove 52.
0 to the drain 52 effectively.
