Description

  The present invention relates to a floor structure suitable for floors of apartments, houses, offices, stores, etc., especially floors of indoor and outdoor corridors, stairs and balconies of apartments, and floor materials used therefor. A floor structure that does not swell or peel off the flooring material affixed to the flooring, and that can be easily peeled off and replaced by the flooring material when the floor is renewed (renovated), and the floor used for this It relates to materials.

  Conventionally, when flooring is laid on floors such as corridors and balconies inside and outside apartment buildings, one-part curable polyurethane adhesive or one-piece is usually used to ensure the adhesion between the floor base and the flooring. The flooring material is firmly fixed (adhered) to the floor base using a floor adhesive such as a liquid curable modified silicone adhesive.

  Laying the flooring with the floor adhesive as described above improves the adhesion between the flooring and the flooring, and maintains excellent adhesion over a long period of time. While it is possible to eliminate problems such as part of the flooring swelling due to moisture rising from the floor after construction, or the edge of the flooring rising up, it is possible to renew the floor. This is one of the factors that cause the efficiency reduction and the cost increase of the renovation work because the floor material cannot be easily peeled off from the floor base.

  On the other hand, a floor structure in which a long floor sheet and a floor base are bonded, and the relationship between the long floor sheet and the floor base is composed of an adhesive portion (a) and a non-adhesive portion (b), and A floor structure in which the bonding portion (b) communicates is known (Patent Document 1).

  In such a floor structure, moisture or the like rising from the floor base is discharged through the communicating non-adhesive portion (b), so that it is possible to prevent the long floor sheet from swelling. However, since a long floor sheet is laminated and pasted on the floor adhesive applied to the floor base, there is a problem that it is difficult to quickly position the stacked long floor sheet while shifting it. If the sheet is pasted with floor adhesive, the adhesive strength of the adhesive part is high, so it is difficult to peel off the long floor sheet when renewing the floor, and it is long at the boundary between the non-adhesive part and the adhesive part. There was also a problem that the floor sheet was easily torn. Also, when sticking or peeling a floor sheet on a floor such as a balcony or open corridor where an obstacle such as an air conditioner outdoor unit is installed, lift the obstacle temporarily and lift the floor sheet. It is required to quickly position and paste, or peel off, but in the floor structure where the floor adhesive is applied to the floor base and the floor sheet is partially adhered and pasted as described above, There was a problem that the floor sheet could not be quickly positioned and pasted at the obstacle installation location on the floor base and its surroundings, and could not be quickly and neatly removed while the obstacle was lifted.

  FIG. 1 is a partial sectional view showing an embodiment of a floor structure according to the present invention, FIG. 2 is an exploded partial sectional view showing a state before the floor material of the floor structure of the embodiment is applied, and 1 is concrete The floor base made of 2 and the floor material 2 are shown. The floor base 1 is not limited to a concrete base, and may be a metal floor base or a wooden floor base. In addition, the “floor ground” referred to in the present invention includes a floor of a staircase.

  As shown in FIG. 2, the flooring 2 of the present invention used in the floor structure of this embodiment includes a flooring main body 2a, an adhesive layer 2b provided on the lower surface of the flooring main body 2a, and And a net-like body 2c provided to be exposed on the lower surface of the adhesive layer 2b, and may be a long flooring or a tile-like flooring. In the case of a long flooring, a flooring body 2a having a wall thickness of about 1 to 3 mm and a width of about 50 to 200 cm is preferably used. Those having a thickness of about 1 to 5 mm and a side length of about 10 to 50 cm are preferably used (in addition to a rectangular tile shape, a tile-like flooring is not only a rectangular tile shape but also a circular, polygonal, or indefinite shape). Needless to say, it may be.)

  As shown in FIG. 1, the floor material 2 is placed on the floor base 1 and positioned, and the mesh body 2 c comes into contact with the floor base 1 and the adhesive of the adhesive layer 2 b is the mesh body 2 c. Is attached to the floor substrate 1 through the opening 21c (see FIGS. 2 and 3). That is, the flooring 2 is placed on the floor substrate 1 and positioned, and then pressed from above, so that the net 2c sinks into the adhesive layer 2b as shown in FIG. The pressure-sensitive adhesive 21b extruded from the pressure-sensitive adhesive layer 2b to the floor base 1 side through the opening 21c is attached to the floor base 1 so that it is attached to the floor base 1.

  In this floor structure, as described above, the floor material 2 is partly attached to the floor base 1 by the adhesive agent 21b only in the opening region of the mesh body 2c, so that the area ratio occupied by the opening 21c is different. By variously selecting the mesh 2c and adjusting the sticking area of the flooring 2, the flooring 2 will not be peeled off or rolled up at all times, but the flooring 2 can be easily renewed (pasted). The flooring material 2 is stuck with an appropriate sticking strength (sticking strength) that can be peeled off, and the contact interface between the net 2c that is not stuck and the floor base 1 is moisture rising from the floor base 1, From the adhesive layer 2, a solvent, a reactive gas, and the like are volatilized.

  The floor material body 2a of the floor material 2 is made of a synthetic resin or rubber sheet, and the floor material body 2a made of a single layer sheet is shown in FIGS. 1 and 2, but is limited to a single layer sheet. It is not a thing, but it is a floor material body consisting of a two-layer sheet in which the surface layer and the back layer are laminated, a three-layer sheet in which the surface layer, the intermediate layer and the back layer are laminated, and a laminated sheet in which a reinforcing fiber layer is sandwiched. There may be. In addition, a floor material body in which a large number of small protrusions for preventing slipping are formed on the surface, a floor material body in which a colored pattern or a pattern is formed, and the like are preferably used. As a preferable material resin of the flooring main body 2a, a thermoplastic synthetic resin such as a soft vinyl chloride resin, an olefin resin mainly composed of polypropylene or polyethylene, and the like can be given.

  The adhesive layer 2b of the flooring 2 is a layer formed by applying an adhesive or an adhesive. When these adhesives are pressed at the time of construction, the net 2c needs to sink (the adhesive layer 2b is partially extruded toward the floor substrate 1 through the opening area of the net 2c). Those that are viscoelastic or flowable after application are used. As the former pressure-sensitive adhesive, an acrylic, rubber-based, or silicone-based pressure-sensitive adhesive is used, and an acrylic-based pressure-sensitive adhesive is particularly preferably used. The thickness of the adhesive layer 2b formed with these pressure-sensitive adhesives should be in the range of 0.1 to 3 mm, particularly in the case of the adhesive layer 2b formed with an acrylic pressure-sensitive adhesive, A thickness of about 0.2 mm is optimal. Moreover, as the latter adhesive, urethane, epoxy, modified silicone, vinyl acetate, acrylic and the like are used, and urethane adhesive is particularly preferably used. The thickness of the adhesive layer 2b formed with these adhesives should be in the range of 0.2 to 3 mm, particularly in the case of the adhesive layer 2b formed with a urethane-based adhesive, A thickness of about 2 mm is optimal.

  The net 2c provided to be exposed on the lower surface of the adhesive layer 2b of the flooring 2 serves to adjust the adhesive strength of the flooring 2 and to form a passage for moisture, volatile solvent, reaction gas, and the like. And the role of preventing the adhesive from remaining on the floor base 1 when the flooring 2 is peeled off, and the role of reinforcing the flooring 2 so as not to be broken when the flooring 2 is peeled off, For example, it is made of a synthetic resin mesh sheet (including a mesh film) in which a large number of openings 21c are formed in a fixed arrangement pattern, or a synthetic resin fiber, a fiber such as an organic fiber or an inorganic fiber (mesh yarn). Netted nets are used. As the material resin of the former mesh sheet, ester resins such as vinyl chloride resin, acrylic resin and polyethylene terephthalate, and olefin resins such as polyethylene and polypropylene are suitable, and polypropylene is particularly preferably used.

  The mesh body 2c used for the flooring 2 of the present embodiment is a polypropylene mesh sheet formed by arranging square openings 21c vertically and horizontally as shown in FIG. 3, and is a length of one side of the opening 21c. Is about 2 to 50 mm (preferably about 5 to 10 mm), and the distance between the openings (ie, the width of the mesh line corresponding to the non-opening region) is about 1 to 50 mm (preferably about 2 to 10 mm). Has a thickness of about 0.3 to 3 mm (preferably about 0.5 to 1 mm). Depending on the length of one side of the opening 21c and the mutual distance between the openings, the mesh sheet 2c has various area ratios (opening ratios) of the openings 21c in the mesh sheet 2c. However, in the flooring 2 of the present embodiment, The area of the opening 21c is such that a 90 ° peel test is performed based on JIS A 5536, and the adhesive strength (peel strength) of the flooring 2 is within the range of 10 to 70 N / 25 mm, preferably 20 to 40 N / 25 mm. Select the type of adhesive for the mesh sheet 2c having the ratio (opening ratio) and the adhesive layer 2b, so that the flooring 2 will not be peeled off or rolled up at all times (during use). The flooring 2 can be easily peeled off (at the time of replacement).

  The shape of the opening 21c of the reticulated body 2c is not limited to a square, but includes various shapes such as regular polygons such as regular triangles, regular hexagons, regular octagons, isosceles right triangles, rectangles, rhombuses, circles, and ellipses. It can be a shape. Further, the arrangement pattern of the openings 21c is not limited to the vertical and horizontal arrangement patterns, and various arrangement patterns such as a diagonal arrangement and a staggered arrangement pattern can be used.

  On the other hand, when the net-like body 2c is a net made of synthetic resin fiber or the like, the net of the fibers (intersection of the net yarn) is knotted by knotting the net by knotting or joining the fibers, as well as the knot of the fibers. A net that is not used may be used, the length of one side of the opening 21c is about 2 to 50 mm (preferably about 5 to 10 mm), and the fiber thickness is about 0.2 to 2 mm (preferably 0.3 to 1 mm). )And it is sufficient. The shape of the opening (mesh) of the net can also be a desired shape such as a square, a rectangle, a regular triangle, a diamond, or a regular hexagon.

  Even when any of the nets 2c is used, the adhesive strength (peel strength) of the flooring material 2 is 10 to 70 N / 25 mm, preferably 20 to 40 N / 25 mm in the 90 ° peel test based on JIS A 5536 as described above. It is important to select the aperture ratio of the reticulate body 2c and the type of the adhesive agent for the adhesive agent layer 2b so as to fall within the range.

  In the floor structure as described above, the adhesion strength of the flooring material 2 to the floor base 1 is appropriately adjusted by the mesh 2c, so that the flooring material 2 is prevented from peeling off and the edge of the flooring material 2 is prevented from rolling up. The floor material 2 can be easily peeled off when the floor is renewed. Moreover, when the net 2c is provided on the lower surface of the pressure-sensitive adhesive layer 2b of the flooring 2, the flooring 2 can be peeled cleanly so that no sticking agent remains on the floor base 1 side by the net 2c. In addition, since the flooring 2 itself is reinforced by the mesh 2c, the flooring 2 can be easily peeled off without breaking the flooring 2 with a peeling force. And since the water | moisture content which rises from the floor base 1, the solvent volatilized from the adhesive layer 2b, a reactive gas, etc. are discharged | emitted outside through the contact interface of the mesh body 2c and the floor base 1, the flooring 2 There is no longer any partial blistering.

  Further, in this floor structure, in the initial stage of positioning the flooring 2 on the floor base 1, the net-like body 2c provided exposed on the lower surface of the adhesive layer 2b of the flooring 2 is the adhesive layer. Since the adhesive layer 2b is in a substantially non-contact state with the floor base 1 by being interposed between the floor base 2 and the floor base 1, the positioning work and the spreading work of the floor material 2 can be easily performed. . Then, simply pressing the flooring 2 from above and sticking the adhesive 21b extruded from the adhesive layer 2b through the opening 21c of the mesh body 2c to the floor base 1 side to the floor base 1 makes it easy. Since the flooring 2 can be affixed, the workability is very good.

  FIG. 4 is a partial sectional view showing another embodiment of the floor structure according to the present invention, FIG. 5 is an exploded partial sectional view showing a state before the floor material of the floor structure of the embodiment is pasted, and FIG. 6 is stuck. It is a decomposition | disassembly fragmentary sectional view of the floor structure of the embodiment which shows the state which left the property improvement sheet | seat on the floor base | substrate and peeled off the flooring material.

  In the floor structure of the embodiment shown in FIG. 4, the adhesive property improving sheet 1a is bonded and fixed to the surface of the floor base 1 with the floor adhesive 1b, and the net 2c of the flooring 20 is in contact with the adhesive property improving sheet 1a. In addition, the adhesive agent 21b of the adhesive agent layer 2b of the flooring 20 is attached to the adhesive property improving sheet 1a through the opening of the mesh 2c.

  As shown in FIG. 5, the flooring 20 used in this floor structure includes a flooring main body 2a, an adhesive layer 2b provided on the lower surface of the flooring main body 2a, and an adhesive layer 2b. A reticulate body 2c provided exposed on the lower surface, and an adhesive property improving sheet 1a provided on the lower surface of the reticulated material 2c, the adhesive property improving sheet 1a being an adhesive agent through the opening of the reticulated material 2c. It is stuck with the sticking agent 21b extruded from the layer 2b.

  The sticking property improving sheet 1a is applied to the floor base 1 when the surface state of the floor base 1 is poor and inferior in sticking property, or when the floor base 1 is inferior in sticking property due to the material. Synthetic resin or rubber sheet (including film), metal thin plate, etc., which plays a role of improving adherence and has good adherence with the adhesive of the adhesive layer 2b of the flooring 20 Is used. As the synthetic resin sheet, a urethane or vinyl chloride sheet, an FRP sheet, or the like is used, and a urethane sheet is particularly preferably used. The thickness of the sticking property improving sheet 1a is not particularly limited, but is preferably in the range of 0.5 to 3 mm. In the case of a urethane-based sheet, the thickness is optimally about 2 mm.

  The floor material body 2a, the adhesive layer 2b, and the mesh body 2c of the floor material 20 are the same as the floor material body 2a, the adhesive layer 2b, and the mesh body 2c of the floor material 2 described above. Is omitted.

  As the adhesive 1b for floors for adhering and fixing the adhesion improving sheet 1a to the floor base 1, a one-component reactive urethane adhesive, a one-component reactive modified silicone adhesive, a two-component reactive urethane adhesive, A two-component reaction type epoxy adhesive is preferably used, and a one-component reaction type urethane adhesive is preferably used in terms of workability and water resistance. These floor adhesives 1b have a bonding strength (peeling strength) of 20 to 100 N / 25 mm, preferably 20 to 70 N / 25 mm, when a 90 ° peel test is performed on the flooring based on JIS A 5536. It is important to select something that fits inside.

  The floor adhesive 1b is preferably applied to the floor base 1 using a comb iron so that the convex lines of the floor adhesive 1b are formed in a comb shape. It is preferable to apply so that the height of the ridges 1b (height after construction) is 0.2 to 3 mm, the width of the ridges is 1 to 3 mm, and the interval between the ridges is 1 to 5 mm. In the present embodiment, the floor adhesive 1b is applied such that the height of the ridges is 2 mm, the width of the ridges is 2 mm, and the interval between the ridges is 3 mm.

  In the floor structure of the embodiment shown in FIGS. 4 and 5, the floor adhesive 1 b is applied to the floor base 1 so that comb-like ridges are formed, and then the floor material 20 is stacked on the floor adhesive 1 from above. It is constructed by pressing and adhering and fixing the sticking property improving sheet 1a of the flooring material 20 to the floor base 1, and the sticking property of the floor base 1 can be improved by the sticking property improving sheet 1a. This is a useful floor structure when the surface state of 1 is inferior and inferior in adherence, or when the floor substrate 1 is inferior in adherence due to the material. Furthermore, since the flooring main body 2a and the sticking property improving sheet 1a are used in combination, a double waterproof structure is formed, so that an extremely effective structure can be achieved from the viewpoint of waterproofness on an outdoor floor where rain falls. It can be said.

  Of course, this floor structure may be constructed by applying the floor adhesive 1 to the floor base 1 and adhering and fixing the adhesive property improving sheet 1a, and then affixing the floor material 2 described above.

Has the advantage of greatly improving. Further, when renewing the floor, the adhesive strength of the adhesive property improving sheet 1a by the floor adhesive 1b is larger than the adhesive strength by the adhesive agent 21c through the opening 21c of the net 2c. As shown in FIG. 6, the flooring 20 is easily and cleanly peeled off at the interface between the mesh 2 c and the adhesion improving sheet 1 a, and the adhesion improving sheet 1 a remains on the surface of the floor substrate 1. . Therefore, the floor material can be efficiently replaced simply by overlaying the above-described floor material 2 on the adhesive property improving sheet 1a and pressing from above.

  FIG. 7 is a partial cross-sectional view showing still another embodiment of the floor structure according to the present invention. This floor structure is a balcony in which an air conditioner outdoor unit 3 serving as an obstacle to affixing flooring is installed so that it can be lifted. A floor material 2 and another floor material 22 are pasted on a floor base 1 such as a corridor.

  That is, at the obstacle installation location (the air conditioner outdoor unit installation location) of the floor base 1 and the surrounding location (around the obstacle installation location, generally in the range of several centimeters to several tens of centimeters), the floor described above is used. A flooring 2 comprising a material body 2a, an adhesive layer 2b provided on the lower surface thereof, and a net 2c exposed on the lower surface thereof is used, and the net 2c contacts the floor base 1 At the same time, the adhesive of the adhesive layer 2b is attached to the floor base 1 through the opening of the mesh 2c, and the floor material 2 is attached. And in the other location of the floor foundation 1, the other floor material 22 made of the conventional synthetic resin is stuck with the floor adhesive 1b, and the joint portion between the floor material 2 and the other floor materials 22, 22 is formed. It is sealed with a sealing material 4 such as a synthetic resin welding rod or sealing material.

  In such a floor structure, the flooring 2 itself is easily positioned, pasted, and peeled off as described above, so the air conditioner outdoor unit 3 that is an obstacle is temporarily lifted (lifted). The floor material 2 can be quickly positioned and pasted at the obstacle installation location of the floor base 1 and its surrounding locations, and can be quickly and neatly peeled off, thereby meeting conventional demands. And this floor structure has the workability as a whole as compared with the case where other floor materials 22 made of synthetic resin are bonded to the entire floor base 1 on which obstacles are installed as in the prior art. There is an advantage to improve, and since the joint portion between the flooring 2 and the other flooring 22 is sealed with the sealing member 4, there is no fear that rainwater or the like penetrates into the floor base 1 from the joint portion. .

  In the floor structure of the above embodiment, the edge of the floor material is not processed, but if necessary, the edge of the floor material is sealed with a synthetic resin welding rod or sealing material. Needless to say, it is possible to prevent drowning and intrusion of rainwater or the like on the back side of the flooring.
