Description

TECHNICAL FIELD The present invention relates to a floor covering material that can be easily constructed and can prevent rolling up when subjected to strong wind.

Conventionally, the technology for laying floor materials on verandas, balconies, rooftops, etc. to form decks is to fix a plurality of fixed substrates with locking grooves on joists and cut them according to the dimensions of the balcony. A method has been used in which the protrusion on the back side of the long deck material is press-fitted into the locking groove of the fixed substrate.

For example, as disclosed in Patent Document 1, as a floor decorative material configured to cover a floor surface by laying a floor material on a slab such as concrete, a member formed by molding a rigid synthetic resin material into a rectangular shape Adhering and fixing a frame body in which a plurality of legs are integrally formed to form a drainage space between the back surface side and the slab surface, and a surface material such as synthetic resin or tile on the upper surface of the frame body Alternatively, a unit type floor decorative material having an integrally molded structure has been put into practical use.
However, when such unit-type floor decorative materials are laid outside such as a balcony or a veranda, if the wind blows into the lower surface side (back surface side) of the floor decorative material, the entire floor decorative material laid will swell. There was a case.

In order to eliminate the rolling up of the floor decorative material, for example, in Patent Document 2, when a floor surface is formed by laying a tile unit, a synthetic resin having a water permeable opening at least around the floor surface. A tile unit laying structure is disclosed in which a floor mat is laid to reduce the influence of wind.
However, when a synthetic resin floor mat having such a water-permeable opening is laid, if the laying width is small, the ratio of the wind entering the lower surface of the adjacent floor decorative material is increased, and there is no effect. For this reason, a wide laying width is required, and there are problems that the appearance is poor and that dust and dirt easily enter over time.

In Patent Document 3, a wind inlet is provided at the end of the floor decorative material, and the wind that has flowed from the inlet to the lower side of the panel surface of the floor decorative material is guided to be sent out above the panel surface. A method of installing a wind guide panel having a ventilation path is disclosed.
However, even when such a method is used, the wind resistance is not sufficient, and the floor decorative material sometimes swells when subjected to strong winds.

Also, in small-scale buildings such as houses, it may be possible to lay flooring materials by individuals rather than specialized contractors, so it was necessary to consider workability etc. for flooring materials. .

It is an object of the present invention to provide a floor decorative material that can be easily constructed and can prevent rolling up when subjected to a strong wind.

The present invention is a floor decorative material that is laid on a floor surface and constitutes a floor, and includes a unit floor material and a cover material that covers an end of the unit floor material, and the unit floor material has a large number of openings. It has a hole and can be cut along each opening, and the cover material is a floor decorative material fixed to the unit floor material at an opening at an end of the unit floor material.
The present invention is described in detail below.

The present inventor can relieve the pressure difference between the front and back surfaces of the unit flooring by using the unit flooring provided with a large number of holes, and further, at the end of the unit flooring. It has been found that by fixing a cover material for imparting wind resistance, it is possible to prevent swelling when subjected to strong winds. In addition, the unit flooring can be cut along each opening so that the dimensions can be easily adjusted, and the cover material can be fixed to the opening at the end of the unit flooring. The present inventors have found that construction can be easily performed even when laying work is performed, and the present invention has been completed.

The floor decorative material of the present invention includes a unit floor material and a cover material that covers an end of the unit floor material.
The unit flooring has a large number of holes. The opening of the unit flooring serves to relieve the pressure difference between the front and back surfaces of the unit flooring, to drain rainwater, etc., and to serve as a part for fixing the cover material at the end of the unit flooring Excellent design and walking feeling. Moreover, since the said unit flooring can be cut | disconnected along each opening, the adjustment of a dimension becomes easy according to the magnitude | size of a laying place.

The shape of the opening in the unit flooring is not particularly limited, but it is easy to adjust the dimensions by cutting along each opening, so a rectangular formed from the lattice members on the four sides of the unit flooring The shape is preferred.

The preferable lower limit of the hole area ratio of the unit flooring is 25%, and the preferable upper limit is 90%. If the hole area ratio is less than 25%, the effect of alleviating the pressure difference between the front and back surfaces of the unit flooring due to the holes may not be sufficiently exerted, or the drainage function may be reduced due to clogging. Then there is. When the opening ratio exceeds 90%, the load resistance is lowered, and it becomes easy to break, the design property is lowered, or the walking feeling is lowered. In addition, it becomes difficult to manufacture the unit flooring. A more preferable lower limit of the above-mentioned hole area ratio is 30%, and a more preferable upper limit is 70%.
In the present specification, the above “opening ratio” means the ratio of the total opening area in plan view to the outer frame area of the unit flooring.

The shape and size of one opening of the unit floor material is not particularly limited. For example, when the cover material is fixed to the unit floor material by a nail provided on the cover material described later, at least the opening in which the nail is fixed It is preferable that the shape of this is a rectangular shape, and the width of the opening of the portion where the claw is fixed in the opening is 3 to 30 mm. If the width of the opening is less than 3 mm, not only will it be difficult to fix the cover material to the opening, but also the drainage will be worse, clogging with dust will be difficult, and manufacturing will be difficult. There are things to do. When the width of the opening is larger than 30 mm, it is difficult to adjust to the target dimension when cutting along each opening to adjust the dimensions, or foreign matters such as dust are likely to fall into the opening. Or the feeling of walking over the opening may be reduced.

The unit flooring may have a groove that can be easily cut without using a cutting tool when cutting along each opening.

The unit floor is provided with a leg on the back side of at least one opening, and the leg has at least a part of a peripheral member forming the opening of the unit floor extending on the back of the unit floor. It is preferable that a leg side surface portion is formed, and an end portion of the leg is formed with a landing portion for landing on the floor surface.
By having a leg on the back side of at least one opening of the unit flooring, a drainage space is provided between the unit flooring and the floor surface. Since the opening and the leg form a drainage channel, drainage is improved, and a clean environment in which bad odor due to clogging of dirt and corrosion of stagnant water is unlikely to occur can be provided.

The leg side surfaces of the legs of the unit flooring are opposed to each other in consideration of load resistance, drainage, air permeability, etc. when the opening is a rectangular shape formed from the lattice members on the four sides of the unit flooring. It is preferable that the leg side surface portion of the leg is formed to extend from the lattice member of the two sides to the back side of the unit floor material, but the unit floor material is formed from the lattice member of one side or two adjacent sides or three sides. A leg side surface portion of the leg may be formed extending to the back surface side.

In the unit flooring, at least another part of the peripheral member that forms the same opening is appropriately selected to form the leg side surface portion of the leg provided on the back surface of the unit flooring, and as a result, the same unit flooring A plurality of legs may be formed so as not to overlap the back side of the opening.

The height of the landing part of each leg of the unit floor material is not particularly limited as long as the leg is not broken with respect to the load applied to the floor decorative material, but the amount of material used and the product weight are reduced. It is preferable to design the space as small as possible in consideration of drainage and air permeability of the space formed between the back surface side of the flooring and the floor surface.
The height of each leg of the landing portion may be changed for each leg in accordance with the shape of the floor surface on which the floor decorative material of the present invention is laid.

The shape of the landing surface of the flooring portion is preferably configured to correspond to the shape of the floor surface on which the floor decorative material of the present invention is laid, and may be a flat shape, but a convex shape, a concave shape Further, it may be a wavefront shape or an inclined surface shape, and is preferably formed in a continuous convex curved surface shape. Forming the above-mentioned continuous convex curved shape prevents extreme loads from being applied to the periphery of the landing surface of the legs, and prevents the floor from being damaged by the load received from the legs of the floor decorative material. can do.
In addition, although the said continuous convex curved surface shape is not specifically limited, For example, the vertical cross section of a landing part has a circular arc shape, an elliptical arc shape, etc., for example.

The shape of the landing surface of the landing portion is preferably maximized by adding the cross-sectional shape of the leg side surface portion to the cross-sectional shape of the opening.
If the shape of the landing surface of the above-mentioned landing part becomes larger than the shape of the cross-sectional shape of the opening plus the cross-sectional shape of the leg side surface part, it becomes difficult to form the unit floor material and the leg integrally, and productivity It is disadvantageous from the viewpoints of handling, transportation, construction, cost and environment.

The area of the landing surface of the landing portion is preferably substantially equal to the cross-sectional area of the opening. Specifically, the area of the landing surface of the landing portion is 70% or more of the cross-sectional area of the opening. It is preferable to set it as the magnitude | size. If the area of the landing surface of the landing portion is less than 70% of the cross-sectional area of the opening, it is possible to reduce the load locally applied to the floor surface by the leg portion receiving the load. Disappear.

In addition, by making the size of the landing surface of the landing portion of the leg substantially equal to the cross-sectional shape including the opening of the unit flooring and the lattice member around the opening forming the opening, The legs can be integrally injection-molded, and a secondary process such as bonding the unit flooring and the legs or bonding a cushioning material to the legs becomes unnecessary. Therefore, there is no inclination, deformation, vibration or the like of the floor decorative material when a load such as walking of a person is applied, so that discomfort during walking or the like is eliminated, and a sense of stability and a sense of security can be given.

The unit flooring is preferably made of a resin material that can be injection-molded from the viewpoints of productivity, handleability, transportability, workability, cost, environment, and the like.
The resin material is not particularly limited, and examples thereof include thermoplastic resins such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyvinyl chloride, and acrylonitrile-butadiene-styrene copolymer.
If necessary, a heat stabilizer, a stabilizing aid, a lubricant, a processing aid, an antioxidant, a light stabilizer, a pigment, a filler and the like may be added to the resin material.

In the floor decorative material of the present invention, the cover material is fixed to the unit floor material at the opening at the end of the unit floor material. The floor decorative material of the present invention is easy to construct because the cover material is fixed in the opening of the unit floor material.

As a method of fixing the cover material at the opening of the end portion of the unit floor material, since the construction is easy, the cover material is provided with a claw that can be inserted into the opening of the end portion of the unit floor material. It is preferable to insert and fix to the opening at the end of the unit flooring. Therefore, it is preferable that the cover material has a claw for being inserted into and fixed to the opening at the end of the unit floor material.
When fixing a cover material to a unit flooring with the said nail | claw, it is preferable that a nail | claw has a return | turnback so that it may not come off easily from the opening of a unit flooring.

In addition, if the width of the nail is made smaller than the width of the opening of the portion to which the nail is fixed, the floor surface on which the dimensional error and thermal expansion / contraction of the unit flooring are absorbed or the floor decorative material of the present invention is laid The cover material can be securely fixed to the unit flooring material by absorbing the unevenness. Specifically, the width of the nail is preferably 0.5 to 2 mm smaller than that of the nail. If the difference between the width of the fixed opening and the width of the claw is smaller than 0.5 mm, thermal expansion and contraction may not be sufficiently absorbed. If the difference between the width of the hole to be fixed and the width of the nail is larger than 2 mm, the fixation may be incomplete when subjected to strong winds, which may reduce the feeling of walking or the design. is there.

Examples of the material of the cover material include a resin material and a metal material. Especially, it is preferable to be comprised with the resin material similar to what was illustrated with the said unit flooring. By using the resin material, it becomes easy to cut the cover material, so that the construction at the corners and the corners becomes easy.
In addition, when the cover material is fixed to the unit floor material by the claw, the claw is made of a resin material, so that the claw is easily elastically deformed when inserted into the opening of the end portion of the unit floor material. Therefore, construction becomes easy.
