Description

  The present invention mainly relates to a floor covering material for covering a floor surface of a balcony or an outdoor shared corridor of an apartment house, and a floor structure using the same.

  In recent years, balconies and outdoor shared corridors in apartment buildings have been covered with floor sheets for the purpose of improving aesthetics, preventing leakage of concrete frames, reducing walking noise, and mitigating impact during falls. It is coming.

  In order to improve tear resistance and dimensional stability, a floor sheet covering such a floor surface is a two-layer waterproof sheet composed of an upper layer portion of a hard vinyl chloride sheet and a lower layer portion of a soft vinyl chloride sheet. In many cases (Patent Document 1).

  However, the waterproof sheet of the two-layer structure as described above is excellent in tear resistance and dimensional stability, but has low flexibility, so when trying to cover the floor surface of an outdoor shared corridor of a balcony or an apartment house, in particular, There was a problem that the processing of the sheet edge was difficult and the workability was not good.

  In other words, simply attaching a waterproof sheet to the floor surface of a balcony or an outdoor shared corridor of an apartment house may cause water to enter from the edge of the sheet and wet the concrete frame. If the concrete frame gets wet with water, the mortar is neutralized or a rust of the steel frame is induced. Therefore, as shown in FIG. The sealing process is applied.

  The floor surface F of the outdoor shared corridor of the balcony or the apartment house is provided with a water gradient of about 1/200 to 3/100 so that the water on the floor surface F is guided to the drainage groove 6 as described above. When the edge of the waterproof sheet 100 is sealed with the sealing agent 5, the sealing agent 5 acts like a weir, and the water flowing along the water gradient is blocked and accumulated. The surface F is not very dry, which is not preferable in terms of aesthetics, and a pedestrian may slip and fall.

  In addition, as with the floor surface F of the outdoor shared corridor of the balcony or the apartment house, it has become common to waterproof the drainage groove 6 as well, but the waterproof sheet 100 having the two-layer structure is described above. As shown in FIG. 8, the coating film is applied from the end of the floor surface F on the drainage groove 6 side to the inner surface of the drainage groove 6. This was achieved by forming the waterproof layer 101.

  However, the waterproof coating layer 101 needs to be formed in layers (usually about three layers) in order to improve durability, and it takes time to cure and dry for each layer, so it takes time to construct. There was a problem. Further, most of the companies that form the waterproof coating layer 101 and the companies that lay the waterproof sheet 100 are different companies, which is not preferable from the viewpoint of workability and cost.

  On the other hand, when processing the sheet edge on the wall side (living room side) opposite to the drainage ditch, the waterproof sheet 100 having the two-layer structure as described above is not flexible, and in particular, the processing of the entrance / exit corner of the balcony is not possible. Because it is difficult, use a waterproofing steel plate formed so as to follow the shape of the entrance / exit corner, a soft resin waterproof sheet covering the waterproofing steel plate, and a soft resin entrance / exit corner cover fixed to the entrance / exit corner Are often applied (Patent Document 2).

  If the entrance / exit corner of the balcony is treated in this way, members such as a water resistant steel plate, a soft resin tarpaulin, and a soft resin entrance / exit cover are required, which is not only troublesome to construct but also costly. There was a problem of becoming bulky.

  The present invention has been made in view of the above problems, and the problem to be solved is a floor that can cover not only the floor surface but also the drainage groove, and has a very good appearance, waterproofness, and workability. It is to provide a covering material and a floor structure using the same.

  In order to achieve the above object, a floor covering material according to the present invention is a long floor covering material, and has a region A formed of a soft or semi-rigid thermoplastic resin and is more flexible than the region A. It consists of a high region B, and the region B is integrally provided in a strip shape on the edge of the region A.

  In the floor covering material of the present invention, in the above floor covering material, the region A is a region covering the floor surface, and the region B is part or all of the drain groove inner surface from the end of the floor surface on the drain groove side. It is preferable that it is the area | region which covers. Moreover, it is preferable that a fiber layer is laminated in the middle or the back surface of the region A, and it is more preferable that the thickness of the region B is the same as or thinner than the thickness of the region A.

  The floor structure of the present invention is a floor structure using the floor covering material having the above-described configuration, and covers the floor surface in the area A of the floor covering material, and drains the floor surface in the area B of the floor covering material. A part or all of the inner surface of the drainage groove is covered from the end on the side.

  In the floor covering material of the present invention, a region B having a higher flexibility than the region A formed of a soft or semi-rigid thermoplastic resin is integrally provided in a band shape on the end side of the region A. Even such complicated terrain can be covered by the region B having high flexibility. Therefore, unlike the conventional case, it is not necessary to seal the edge of the covering material on the drainage groove side of the floor surface with a sealant, and in addition, there is no need to form a waterproof coating layer, so water is stagnated. As a result, the aesthetics are improved and the construction time and labor can be greatly reduced. In this way, complex terrain such as drainage trenches is covered by region B, while floors of balconies and outdoor shared corridors of apartment buildings that require tear resistance and dimensional stability are covered by region A. And sufficient durability can be secured. Thus, since the floor covering material of the present invention can integrally cover the drainage groove and the floor surface with a single covering material, the conventional problems can be solved all at once.

  In particular, in the floor covering material having the above-described configuration, the area A is an area that covers the floor surface, and the area B is an area that covers a part or all of the inner surface of the drainage groove from the end of the drainage groove side of the floor surface. Is the most suitable covering material for covering floors and drainage grooves of outdoor shared corridors in balconies and apartment buildings.

  In addition, the floor covering material in which the fiber layer is laminated on the middle or back surface of the region A improves the tear resistance, dimensional stability, and durability of the region A by laminating the fiber layer on the middle or back surface of the region A. In addition, the aesthetics of the floor will be improved.

Furthermore, the floor covering material in which the thickness of the region B is the same as or thinner than the thickness of the region A makes the thickness of the region B the same as or thinner than the thickness of the region A, thereby making the region B more flexible. The workability is further improved and the workability is extremely good, and the flow of water guided along the water gradient is not hindered.
In addition, the thickness here means, for example, even when a protrusion for improving the slip resistance is formed in the region A, the height of the protrusion is not included, and the covering material excluding the protrusion The thickness of a single unit.

  And the floor structure of the present invention uses the floor covering material having the above-mentioned excellent effects, and covers not only the floor surface but also the drainage groove with a single covering material, so that the aesthetics and waterproofness are excellent. It is extremely high and is particularly suitable for the floors of balconies and outdoor shared corridors in apartment buildings.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  The floor covering material 1 of the present invention shown in FIGS. 1 and 2 is a long covering material that can simultaneously cover the drainage groove 6 together with the floor surface F, such as an outdoor shared corridor of a balcony or an apartment house. Or it consists of the area | region A formed with the semi-rigid thermoplastic resin, and the area | region B which was provided in the end side of this area | region A integrally in the shape of a belt | band | zone, and has higher flexibility than the area | region A.

As shown in FIG. 2, the area A of the floor covering 1 is an area for covering the floor surface F such as a balcony or an outdoor shared corridor of an apartment house, and a pedestrian walks on it. Tearability, dimensional stability, and durability are required. Therefore, a region where the intensity of the correspondingly obtained, specifically, it is preferable that the 10% modulus is in the range of 1~5N / mm ^2, in the present embodiment, the 10% modulus is 2N / mm ² It is about.

On the other hand, the area B of the floor covering material 1 is an area for covering the inner surface of the drainage groove 6 from the end of the floor surface F on the drainage groove 6 side, as shown in FIG. Flexibility is required to follow a concave shape without gaps. Specifically, it is preferable that the 10% modulus is in the range of 0.3~1.0N / mm ^2, in the present embodiment, the 10% modulus is in the 0.5 N / mm ² approximately.

  The above measurement was performed under the conditions of a temperature of 20 ° C., a tensile speed of 20 mm / min, a side of a test piece of 10 mm, a thickness of 1.5 mm, a dumbbell No. 1, and a distance between chucks of 70 mm.

  The floor covering material 1 of the present invention in which the flexibility is different between the region A and the region B is formed using a synthetic resin such as a soft vinyl chloride resin or an olefin resin, or rubber. At this time, various methods are conceivable to make the regions A and B different in flexibility. That is, as one of the methods, there is a method in which the regions A and B are formed using resins having different flexibility (the resin in the region B is softer). When different resins are used in the region A and the region B in this way, it is necessary to pay attention to the fact that they are formed of resins having high heat-fusibility with each other.

  Moreover, even if the region A and the region B are formed of a resin having the same composition, the hard and soft performance can be imparted. That is, by adding more plasticizer to the region B than to the region A, the flexibility of the region B can be increased more than that of the region A.

  Further, after forming the region A and the region B with a resin having the same composition, a layer of the same kind or different kind of synthetic resin or the like, having relatively low flexibility and excellent strength, is laminated on the middle or back surface of the region A May be. Furthermore, when forming with the resin of the same composition, the tear resistance, dimensional stability, and durability of the region A are improved by laminating the fiber layer 2 such as a woven fabric or a non-woven fabric in the middle of the region A. The flexibility of the region B can be made higher than the region A.

That is, the fiber layer 2 for improving tear resistance and dimensional stability is laminated in the middle of the region A of the floor covering material 1 of the present embodiment. As the fiber layer 2, glass fiber, synthetic resin fibers such as polyester and olefin, and natural fibers such as hemp are preferably used. By thus laminating the fiber layer 2 in the middle of the region A, tear resistance is increased. Further, the dimensional stability is further improved, and the durability of the floor covering material 1 is also improved. Of course, the region A and the region B are formed of resins having different flexibility, or a lot of plasticizers are added to the region B, and further, the fiber layer 2 is laminated in the middle of the region A to reduce the difference in flexibility. It may be given.
In addition, you may form the backer layer which consists of the same kind or different kind | species synthetic resin etc. on the back surface of the area | region A for various purposes, such as improving the adhesiveness with the floor surface F. FIG. Further, the fiber layer 2 may be laminated not on the back of the region A but on the back surface thereof.

As described above, the floor covering material 1 according to the present invention is formed so as to have different flexibility in the region A and the region B. In order to provide flexibility that can be followed without any problem, the thickness H2 of the region B is made thinner than the thickness H1 of the region A as shown in FIG. If the thickness H1 of the region A is less than 1 mm, the tear resistance and dimensional stability required as a covering material to be coated on the floor surface F cannot be ensured. On the contrary, if the thickness H1 of the region A is thicker than 5 mm, the floor covering material 1 becomes heavier and the workability deteriorates and the cost increases, so the thickness H1 of the region A is about 1 to 5 mm. It is preferable to set. Therefore, in consideration of the above, the thickness H2 of the region B is set to about 0.5 to 3 mm, which is thinner than the thickness H1 of the region A.
The area B of the floor covering material 1 is an area where flexibility is required so that it can be covered along the shape of the drainage groove 6, and therefore it is not preferable to laminate the fiber layer 2 in the area B. If it is in a range that does not hinder the temperature, the expansion and contraction due to the temperature change is relaxed to ensure the dimensional stability of the region B, or the cold or the like is applied to the middle or the back surface of the region B for the purpose of ensuring the adhesion to the floor surface F, You may laminate. Further, on the back surface of the region B, a backer layer made of the same kind or different kind of synthetic resin or the like may be formed for various purposes such as improving adhesion to the floor surface F.

  As shown in FIGS. 1 and 3, the surface of the area A of the floor covering material 1 is provided with a large number of protrusions 3 having a height H3 of about 0.1 to 5 mm in order to improve slip resistance. ing. When providing this protrusion 3, it is necessary to consider the flow toward the bottom of the water so as not to hinder the flow of water guided to the drainage groove 6 along the water gradient. Specifically, as shown in FIGS. 6A and 6B, the shape may be a cylindrical protrusion 3a or a quadrangular prism-shaped protrusion 3b (polygonal casting may be used). In addition, various shapes such as a conical shape, a quadrangular pyramid shape (a polygonal pyramid shape is also possible), a truncated cone shape, and a truncated quadrangular pyramid shape (a truncated polygonal pyramid shape is also possible) are conceivable. Further, the arrangement is not particularly limited, and may be a regular arrangement as shown in FIGS. 6A and 6B, or a random arrangement as long as the flow of water is not hindered. In these (a) and (b), since the flowing water passage 4 reaching the drainage groove 6 is formed by sewing between the protrusions 3a and 3b, the floor covering material can be smoothly formed without hindering the flow of water. 1 can flow down on the surface of the region A and drain into the drain groove 6. However, at this time, if a concave portion is formed on the surface of the floor covering material 1, water stays in the concave portion, so that the formation of the concave portion should be eliminated as much as possible.

  However, as shown in FIG. 6 (c), providing protrusions 3c such as ridges provided in parallel to the drainage grooves 6 that block the water guided to the drainage grooves 6 along the water gradient, That is, it is impossible to adopt a mode in which the flowing water passage 4 reaching the drainage groove 6 is not formed. Moreover, even if the flowing water passage 4 is formed, a shape (for example, relative to the wall side W as shown in FIG. 6 (d)) that stagnates the water flowing along the water gradient. A concave protrusion 3d or the like in which a concave portion is formed is also unacceptable because it causes water to flow down.

  And as shown in FIG. 1, the floor covering material 1 of this invention is a flowing water path | route by providing the location which does not have the said protrusion 3 on the surface of the area | region A at regular intervals (vertical and horizontal direction). 4 is formed. By forming the flowing water passage 4, the water on the floor surface F is guided to the drainage groove 6 and is not easily accumulated on the surface of the floor covering material 1, and the appearance is accentuated, so that the design is improved.

Moreover, you may provide the water conveyance assistance groove | channel 7 as shown in FIG. 7 in the area | region B of the floor covering material 1 of this invention. (A) of FIG. 7 is a perspective view of the floor covering material 1 provided with the water guide auxiliary grooves 7 in the region B, and (b) of FIG. 7 is a construction sectional view thereof. In this way, by forming the water guide auxiliary groove 7 with a certain length from the region A side edge of the region B, the region B is covered from the drain groove 6 side edge of the floor surface F into the drain groove 6. Then, it functions as a water conduit when rainwater or the like flows down from the region A, and rainwater or the like can be led into the drain groove 6 quickly and effectively, which is very preferable.
In addition, it is more effective to provide the water guiding auxiliary groove 7 on the extension of the flowing water passage 4 in the region A. Moreover, it is preferable to provide the water guide auxiliary groove 7 so as to be formed partway along the inner wall of the drainage groove 6. This is because if the water guide auxiliary groove 7 reaches the bottom surface of the drainage groove 6 or near the bottom surface, dirt or dust accumulates and the drainage flowing down the drainage groove 6 is adversely affected.

The floor covering material 1 having the above configuration is formed by the following manufacturing method.
That is, a soft vinyl chloride resin or olefin resin sheet for the backer layer is placed on the support belt. Since the floor covering material 1 of the present invention laminates the fiber layer 2 in the middle of the region A, first, a sheet that is half the thickness H1 of the region A is placed, the fiber layer 2 is laminated thereon, and A pellet is spread on the fiber layer 2. At this time, in the case where a difference in flexibility between the region A and the region B is given using a resin having different flexibility, a highly flexible resin pellet is provided on the region B side of the boundary line between the region A and the region B. Scatter. In addition, when a resin having the same composition is used to give a difference in flexibility between the region A and the region B depending on the amount of plasticizer to be added, a large amount of plasticizer is added to the pellet on the region B side of the boundary line. do it. Further, in order to form the regions A and B so that the thicknesses H1 and H2 are different (thickness H2 is thinner than the thickness H1), the scraped portions of pellets having different heights (the region B than the region A) Can be accommodated by installing a lower). In this way, the pellets are passed through the heating furnace while being placed on the support belt, and the respective pellets in the region A and the pellets in the region B and the pellets at the boundary between the region A and the region B are thermally fused. And seat. Since it is necessary to provide the protrusion 3 on the surface of the floor covering material 1 of the present invention, the floor covering material 1 coming out of the heating furnace is embossed with an embossing roll to complete.
The floor covering material 1 of the present invention can be easily formed by the above-described manufacturing method, but it goes without saying that it may be formed by conventional extrusion molding or the like.

  Next, the floor structure of the present invention using the floor covering material 1 having the above-described configuration is a balcony or outdoor shared corridor provided with a water gradient of 1/200 to 3/100 (in this embodiment, 1/150). As shown in FIG. 2, the floor surface F is covered with the area A of the floor covering material 1, and the area B is provided on the outdoor side of the balcony or the outdoor shared corridor from the end of the floor surface F on the drainage groove 6 side. The entire inner surface of the drainage groove 6 is covered. The floor surface F covered with the floor covering material 1 is not limited to a concrete floor foundation, and any general floor foundation employed in buildings such as a mortar floor foundation can be applied. It is.

  Adhesives (not shown) for adhering the floor covering 1 to the floor surface F and the drainage grooves 6 are urethane type, epoxy type, acrylic type, modified silicone type curable floor adhesives, and rubber type floors. An adhesive is used. In particular, a urethane type or an epoxy type (which may be a two-component mixed type or a one-component type such as a moisture curing type) excellent in water resistance is preferably used.

The wall side W (room side) edge of the area A of the floor covering material 1 adhered to the floor surface F with the adhesive as described above is subjected to a sealing treatment with a sealant 5 as shown in FIG. ing. In addition, the edge of the region B of the floor covering material 1 that covers the inner surface of the drainage groove 6 is also sealed with the sealant 5 at the upper end on the outdoor side of the drainage groove 6. As the sealing agent 5 for sealing the edge of the floor covering material 1, an epoxy-based, urethane-based, silicone-based, modified silicone-based material or a material having good adhesiveness with the floor covering material 1 is preferably used. By sealing the edge of the floor covering material 1 in this way, the finish becomes beautiful, and it is possible to prevent the intrusion of rainwater and the floor covering material 1 from rising.
The drain groove 6 covered by the region B of the floor covering material 1 does not necessarily need to cover the entire inner surface, and may cover only a part of the inner surface as shown in FIG. At this time, it should be noted that the end portion is sealed with the sealant 5. In this case, the above-described waterproof coating layer 101 may be formed on the inner surface of the drainage groove 6 that is not covered with the floor covering material 1.

  The construction method of the floor structure shown in FIG. 2 is not particularly limited. However, when construction is performed in the following process, the boundary between the area A and the area B of the floor covering material 1 is not shifted and high accuracy is achieved. And can be easily coated.

  First, the boundary between the region A and the region B and the edge of the floor surface F on the drainage groove 6 side are aligned and assigned. Next, an adhesive is applied to the floor F corresponding to approximately half of the drainage groove 6 side of the region A, and the region A on the drainage groove 6 side is adhered and fixed, and then the remaining half of the region A (the wall side) An adhesive is applied to the floor surface F corresponding to W), and the floor covering material 1 in the region A is adhered. And after apply | coating an adhesive agent to the inner surface of the drainage groove 6, and sticking the area | region B of the floor covering material 1 along the shape of the drainage groove 6, the edge of the floor covering material 1 is finally used as the sealing agent 5 The construction is completed by carrying out the sealing process.

  The floor structure of the present invention as described above uses the floor covering material 1 composed of the regions A and B having different flexibility, so that the floor surface F and the drainage groove 6 are integrally formed with one floor covering material 1. Since it can be covered, the aesthetics, waterproofness, and workability are extremely good, and it is particularly suitable as a floor structure for outdoor shared corridors in balconies and apartment buildings.

  The floor structure is constructed using the floor covering material 1 described above, but the floor structure shown in FIG. 5 is constructed using a floor covering material 10 described below.

  In the floor covering material 1 described above, the highly flexible region B is provided only at one end side in the length direction of the region A, whereas the floor covering material 10 includes the highly flexible region B. , Provided at both ends in the length direction of the region A. In this way, the floor covering material 10 in which the regions B having high flexibility are provided at both ends of the region A has high flexibility in the region B. Therefore, not only the inner surface of the drainage groove 6 but also the wall W includes the floor covering material 10. The region B can be covered (folded up).

  The floor structure using the floor covering material 10 in which the region B having such high flexibility is provided at both ends of the region A has no dimensional versatility (width direction), but the wall side W is waterproof. Further improvement.
