Description

  The present invention relates to a drain drainage groove member and a floor covering structure using the drain drainage groove member, and more particularly, excellent waterproofness over a long period of time by being watertightly bonded to a floor covering material and attached to a floor base. The present invention relates to a drain drainage groove member and a floor covering structure.

  In apartment buildings such as condominiums, a synthetic resin drain drain groove member is attached to the floor of a veranda or common corridor, and drain water discharged from an air conditioner, etc. is drained through the drain drain groove member to the veranda or common corridor. It drains into the ditch. As such a drain drainage groove member, for example, on the surface of a strip-like sticking plate made of a synthetic resin having a thickness almost equal to a floor covering material (floor sheet) stuck on a floor of a veranda or a common corridor. A shallow drainage drainage channel formed over the entire length is known (Patent Document 1).

  The drain drainage groove member is attached to the floor base of the veranda or common corridor next to the floor covering material made of synthetic resin with a floor adhesive, and usually the seam of the drain drainage groove member and the floor covering material, By welding using a thermoplastic resin welding rod, filling with a sealing agent and sealing, or adhering using a solvent, watertight joining is ensured to ensure waterproofness.

Japanese Patent Laid-Open No. 10-46762

However, when joining the drain drainage groove member and the floor covering material joint as described above by means such as resin welding, sealing, solvent adhesion, etc., if the operator's skill level is insufficient or politeness is lacking, There is a possibility that rainwater or the like may permeate into the back side of the floor covering material or the back side of the drain drainage groove member from the joint due to poor bonding and leak.
In addition, since the joined seam is exposed, there is a possibility that the welding resin and the sealant of the seam are deteriorated with time due to sunlight, temperature change, wind and rain, and the waterproofness is lowered to cause water leakage.

  The present invention has been made under the above circumstances, and the problem to be solved is that even unskilled workers can be watertightly bonded to the floor covering material without causing poor bonding, and are exposed to sunlight and wind and rain. An object of the present invention is to provide a drain drainage groove member and a floor covering structure capable of exhibiting excellent waterproofness for a long period of time even when being applied to an outdoor common corridor or a floor floor of a veranda.

  In order to solve the above problems, a drain drainage groove member according to the present invention is provided on the left and right side surfaces or any one side surface of a groove member body provided with a recessed groove portion for draining drain water, and the lower surface is a lower surface and a surface of the groove member body. A thin and continuous tongue edge portion, and the above-mentioned tongue edge portion for joining the edge portion of the floor covering material overlapped on the tongue edge portion outwards over the entire length of the groove member body It is formed.

  In the drain drainage groove member of the present invention, it is preferable to incline the upper surface of the tongue edge portion so that the thickness of the tongue edge portion gradually decreases toward the tip of the tongue edge portion. And it is also preferable to form a raised part in the upper surface or lower surface of a tongue edge part in parallel with the side surface of a groove member main body over the full length of a tongue edge part.

  The floor covering structure according to the present invention is a floor covering structure in which the drain drain groove member according to the present invention and a floor covering material are adjacent to each other and adhered to a floor base, and the tongue edge of the drain drain groove member It is characterized by sticking and joining the edge part of the floor covering material overlaid on the part.

  In the floor covering structure described above, a plurality of the drain drainage groove member and the floor covering material that are parallel to each other along the joint portion on the corresponding surface of the floor base corresponding to the joint portion of the drain covering member and the floor covering material. It is preferable to form a ridge group composed of ridges of the adhesive of the strip, and to stick the joining portion and the portions near both sides thereof to the corresponding surface of the floor base by the ridge group of the adhesive.

  Further, another floor covering structure according to the present invention is provided with a belt-like sheet that is thin and wider than the groove member body on the lower surface of the groove member body provided with a recessed groove portion for draining drain water, It is a floor covering structure in which a drain drainage groove member formed with a thin tongue edge protruding over the entire length of the groove member main body and a floor covering material are adjoined to the floor base, protruding to the left and right sides or either one side. The tongue edge portion of the drain drainage groove member and the end edge portion of the floor covering material stacked thereon are bonded and joined.

  The drain drainage groove member of the present invention is a drainage drainage by a simple operation of applying a sticking agent on the upper surface of the tongue edge portion for joining and overlaying and sticking the edge of the floor covering material thereon. Since the groove member and the floor covering material can be joined, even an unskilled worker can perform watertight joining without causing poor joining, and the floor covering can be applied over a wide range over almost the entire upper surface of the tongue edge. Since the edge part of a material is water-tightly stuck and joined, the outstanding waterproofness can be exhibited. In addition, since the joint interface between the tongue edge of the drain drainage groove member and the edge of the floor covering is covered with the edge of the floor covering and not exposed, the outdoor corridor is exposed to sunlight or wind and rain. Even if it is applied to the floor base of a veranda, the deterioration of the joint interface over time is suppressed, and excellent waterproofness can be maintained over a long period of time.

  By the way, when the thickness of the tongue edge portion of the drain drainage groove member is constant and the upper surface is not inclined, the edge edge portion of the floor covering material is bent stepwise at the tip portion of the tongue edge portion. If the floor covering material is poor in flexibility, the edge of the floor covering material will be lifted from the tongue edge by the elastic restoring force, making it difficult to join the floor covering material. Even after joining, the edge of the floor covering material may be peeled off from the tongue edge. However, in the drain drainage groove member of the present invention, the edge of the floor covering material is stepped so that the thickness of the tongue edge gradually decreases as it approaches the tip of the tongue edge. Therefore, it is easy to perform the joining work and the possibility of peeling is greatly reduced.

  Further, in the drain drainage groove member of the present invention, the ridge portion formed on the upper surface or the lower surface of the tongue edge portion in parallel with the side surface of the groove member body over the entire length of the tongue edge portion is a floor covering superimposed on the tongue edge portion. When the material edge is pressed and bonded from above, the edge of the tongue and the edge of the floor covering material are in close contact with each other at the raised portion, and this pressure contact and the contact portion of the tongue edge Since it is formed over the entire length, water tightness and bonding strength are further improved. Then, when the ridge is formed on the upper surface of the tongue edge portion, for example, when the tongue edge portion and the floor covering material edge portion are attached using a solvent-based adhesive, the ridge portion is used as a weir. Since the adhesive accumulates on the upper surface of the tongue edge, the solvent does not evaporate until the edge of the floor covering material is finished, and the adhesive part extends in the length direction of the tongue edge. Even if there is a general application leakage, the accumulated adhesive spreads in the length direction to cover the application leakage part, so that the reliability of the adhesion is improved and excellent waterproofness can be secured become.

  The floor covering structure of the present invention has the drain drainage groove member of the present invention and the floor covering material adjoining each other and adhered to the floor base, and the tongue covering of the drain drainage groove member and the floor covering overlaid thereon. Since the edge portion of the material is bonded and joined, as described above, even an unskilled worker can stick and join the tongue edge portion and the floor covering material edge portion in a watertight manner. Even if it is constructed on an outdoor corridor or a floor floor of a veranda exposed to wind and rain, deterioration over time of the joint interface is suppressed, and excellent waterproofness can be maintained over a long period of time.

  Then, in the floor covering structure of the present invention, the joint surface of the drain drainage groove member and the floor covering material and the corresponding surface of the floor base corresponding to the vicinity of both sides thereof are arranged in parallel with the mutual spacing along the joint portion. If a plurality of strips of adhesive strips are formed, and the bonding portion and the vicinity of both sides are adhered to the corresponding surface of the floor base by this adhesive strips, Even if rainwater or the like may invade from the joint between the tongue edge and the floor covering material edge, each protruding line of the adhesive protruding line group becomes a weir and the intruded water becomes the floor covering material and the under floor. It is possible to prevent widespread between the ground.

  Further, like another floor covering structure of the present invention, a thin belt sheet is provided on the lower surface of the groove member main body and wider than the groove member main body, and the thin wall protrudes on either the left or right side or one side of the groove member main body. The drain drainage groove member formed with the tongue edge portion extending over the entire length of the groove member body and the floor covering material are adjacent to each other and adhered to the floor base, and the tongue edge portion of the drain drainage groove member is overlaid thereon. In the same manner as the above-described floor covering structure of the present invention, even the unskilled worker sticks the tongue edge and the edge of the floor covering material in a watertight manner. Can be bonded to outdoor corridors and veranda floors exposed to sunlight, wind and rain, and the deterioration of the bonding interface over time is suppressed, and excellent waterproofness is maintained over a long period of time. Can do.

  A drain drainage groove member 10 shown in FIGS. 1 to 3 is formed by integrally forming tongue edge portions 1a and 1a for bonding on both left and right side surfaces of a groove member main body 1, and the groove member main body 1 has a strip shape. By forming the side bank portions 1c and 1c along the left and right sides of the bottom plate portion 1b, the groove 1d that drains drain water in the space surrounded by the bottom plate portion 1b and the left and right side bank portions 1c and 1c. It is what. A chamfered portion 1i is formed at an angle between the upper surface and the outer surface of the side ridge portions 1c, 1c so that a pedestrian can hardly go over and a wheel such as a carriage can easily get over. And the recessed part 1e, 1e is formed in the lower part of the inner surface of the side bank part 1c, 1c over the whole length of the side bank part, and these convex parts 2a, 2a of the lid member 2 are formed in these recessed parts 1e, 1e. By fitting the projections 2a, 2a projecting outward from the lower portions of the left and right side plates of the lid member 2, the lid member 2 covering the concave groove portion 1d is attached. Although not shown, a plurality of narrow and shallow small grooves are formed over the entire length of the bottom plate portion on the bottom surface of the concave groove portion 1d, that is, the top surface of the bottom plate portion 1b. It is designed to flow smoothly and drain.

  On the left and right side surfaces 1f and 1f of the groove member main body 1, that is, on the outer side surfaces 1f and 1f of the left and right side ridge portions 1c and 1c, the thin tongues whose lower surfaces are flush with the lower surface of the groove member main body 1 The portions 1a and 1a are formed outwardly over the entire length of the groove member main body 1. As shown in FIG. 7, the tongue edge portions 1 a and 1 a are bonded to each other by bonding the edge portion 3 a of the floor covering material 3 on the upper surface, and being bonded with the adhesive 4. As shown in FIGS. 3 and 7, the upper surface of the tongue edge portion 1a is an inclined surface that is inclined so that the thickness of the tongue edge portion 1a gradually decreases toward the tip of the tongue edge portion 1a. .

  Like the drain drainage groove member 12 shown in FIG. 5, the thickness of the tongue edge portion 1 a may be made constant without inclining the upper surface of the tongue edge portion 1 a, but in that case, the edge edge portion 3 a of the floor covering material 3 is used. Is overlapped on the upper surface of the tongue edge portion 1a in a state of being bent stepwise at the tip portion of the tongue edge portion 1a, so that the floor covering material 3 is inferior in flexibility. The edge 3a of the floor covering 3 is lifted from the tongue edge 1a by the elastic restoring force as shown in the figure, so that the joining work is difficult. Even after the joining, the edge 3a of the floor covering 3 is the tongue edge. There is a risk of peeling from 1a. However, if the floor covering 3 is rich in flexibility, such a fear hardly occurs.

  On the other hand, like the drain drainage groove member 10 shown in FIGS. 3 and 7, the upper surface of the tongue edge portion 1a is inclined and the thickness of the tongue edge portion 1a becomes thinner as it approaches the tip of the tongue edge portion 1a. As shown in FIG. 7, the edge 3a of the floor covering 3 is inclined without being bent in a stepped manner and is attached to the upper surface of the tongue edge 1a, so that the floor covering 3 is inferior in flexibility. Even if it is a thing, joining work becomes easy and there exists an advantage that the possibility of peeling will be reduced significantly.

  On the upper surface of the tongue edge portion 1a of the drain drainage groove member 10, as shown in FIGS. 1 to 3, a small raised portion 1g extends over the entire length of the tongue edge portion 1a to the side surface 1f (side bank) of the groove member main body 1. It is formed in parallel with the outer surface 1f) of the part 1c. When such a raised portion 1g is formed, when the end edge portion 3a of the floor covering material 3 superimposed on the tongue edge portion 1a is pressed and bonded and joined from above, the tongue edge portion 1a and the floor covering are joined. The material edge portion 3a is strongly pressed and adhered at the raised portion 1g, and this pressure-welded and closely-contacted portion is formed over the entire length of the tongue edge portion 1a, so that there is an advantage that water tightness and bonding strength are further improved. . Moreover, when sticking the tongue edge part 1a and the floor covering material edge part 3a using a solvent-type sticking agent, the protruding part 1g becomes a dam and a solvent-type sticking agent is the upper surface of the tongue edge part 1a. Therefore, there is no worry that the solvent will be volatilized before the floor covering material edge 3a is pasted, and there is a partial application leakage of the solvent-based adhesive in the length direction of the tongue edge 1a. Even in such a case, since the accumulated solvent-based adhesive spreads in the length direction and can fill the application leakage portion, the reliability of the adhesion is improved and excellent waterproofness can be secured. In addition, when a solvent-based adhesive that dissolves or swells 1 g of the raised portion is used, the raised portion 1 g that is semi-dissolved or swelled by the adhesive becomes substantially flat due to the pressure contact at the time of application. The raised portion 1g is reflected on the surface of the edge portion 3a, so that the bulge hardly occurs.

  A plurality of the raised portions 1g may be formed in parallel with each other on the upper surface of the tongue edge portion 1a, or may be formed on the lower surface of the tongue edge portion 1a. In the case where a plurality of raised portions 1g are formed, the number of places where the tongue edge portion 1a and the floor covering material edge portion 3a are strongly pressed and brought into close contact with each other increases, so that there is an advantage that water tightness and bonding strength are further improved. Further, when the raised portion 1g is formed on the lower surface of the tongue edge portion 1a, it is impossible to improve the adhesion reliability by accumulating a solvent-based adhesive or compensating for an application leakage portion. This is effective because the tongue edge portion 1a and the floor covering material edge portion 3a can be strongly pressed and brought into close contact with each other at the formed position to enhance water tightness and bonding strength. In the case where the raised portion 1g is formed on either the upper or lower surface of the tongue edge portion 1a, the position of the raised portion 1f may be set to the approximate center of the protruding direction (width direction) of the tongue edge portion 1a or a position slightly closer to the tip. preferable.

  In addition, in order to positively accumulate the solvent-based adhesive or to compensate for the application leakage portion, like the drain drainage groove member 11 shown in FIG. 4, on the upper surface on the proximal end side from the raised portion 1 g of the tongue edge portion 1 a, Even if the recess 1h serving as the adhesive agent reservoir is formed over the entire length of the insulating portion 1a, or a similar recess (not shown) is formed on the top surface of the tongue edge portion 1a from the raised portion 1g. Good.

  4 and 5, the drain drainage groove members 11 and 12 are different from that of the drain drainage groove member 10 only in the configuration of the tongue edge portion 1a as described above, and the configuration of the groove member main body 1 is the same. is there. Accordingly, in FIGS. 4 and 5, reference numerals corresponding to corresponding portions of the groove member main body 1 are given, and description of the groove member main body 1 is omitted.

  The material of the drain drain groove members 10, 11, 12 and the lid member 2 is not particularly limited as long as it is a thermoplastic resin. Among them, a soft vinyl chloride resin or the like is preferably used.

  Moreover, although the dimension of each part of said drain drainage groove member 10,11,12 or the cover member 2 is not specifically limited, If a suitable dimension is illustrated, the width | variety of the groove member main body 1 will be about 60-80 mm, and the bottom plate part 1b The thickness is about 1 to 3 mm, the height of the side bank portion 1c (depth of the recessed groove portion 1d) is about 2 to 5 mm, the interval between the side bank portions 1c (width of the recessed groove portion 1d) is about 40 to 50 mm, the lid The width of the member 2 (the width of the top plate portion) is about 40 to 50 mm, the height of the lid member 2 is about 2 to 5 mm, and the thickness of the lid member 2 is about 1 to 3 mm.

  The width W of the tongue edge portion 1a of the drain drainage groove member 10 is about 5 to 30 mm (in the embodiment, 10 mm), and the thickness T of the base end portion of the tongue edge portion 1a is about 0.5 to 3 mm (in the embodiment, 1 mm). ), The thickness t of the tip of the tongue edge 1a is about 0.1 to 2 mm (0.5 mm in the embodiment), the width w of the raised portion 1g is about 0.1 to 1 mm (0.3 mm in the embodiment), The height of the raised portion 1g is about 0.1 to 1 mm (in the embodiment, 0.3 mm). Further, the dimensions of the respective portions of the drain drainage groove member 11 excluding the recess 1h of the tongue edge 1a are the same as the dimensions of the tongue edge 1a of the drain drainage groove member 11, and the width of the recess 1h is 0. About 5 to 3 mm (1 mm in the embodiment), and the depth is about 0.2 to 1 mm (0.5 mm in the embodiment). Moreover, the thickness of the tongue edge part 1a of the drain drain groove member 12 is about 0.5-3 mm, and a width | variety is about 5-30 mm. Since the above-described raised portion 1g and concave 1h are small in size, it seems that the above-mentioned retention effect of the adhesive cannot be expected, but the surface tension of the adhesive effectively A puddle is formed, volatilization is prevented, and an application leakage portion can be compensated. Such an effect becomes more effective by using a dope cement (described later) having relatively low fluidity and high surface tension due to dissolving the resin as an adhesive.

  In addition, it is preferable that the height of the side surface 1f of the groove member main body 1 (the outer surface 1f of the side bank portion 1c) is approximately 1 to 5 mm (2 mm in the embodiment) which is substantially the same as the thickness of the floor covering material 3. When the height of the side surface 1f is the same as the thickness of the floor covering material 3, as will be described later, the gap between the side surface 1f and the end surface of the floor covering material edge portion 3a is filled with a sealing agent 6 or a molten resin to be waterproof. At the same time, the upper surface of the edge portion 3a of the floor covering material and the oblique chamfered portion 1i of the side ridge portion 1c can be continuously finished without a step so that the joined portion can be finished finely.

  The drain drainage groove members 10, 11, 12 are formed with tongue edges 1 a, 1 a for bonding on the left and right side surfaces 1 f, 1 f of the groove member body 1 so that the floor covering materials 3, 3 can be bonded to both sides. However, if it is only necessary to join the floor covering material 3 to one side, the tongue edge portion 1a may be formed on either the left or right side of the groove member main body 1.

  When the tongue edge portion 1a for bonding is formed on the side surface 1f of the groove member body 1 as in the drain drain groove members 10, 11, and 12 described above, the adhesive is applied to the upper surface of the tongue edge portion 1a for bonding. Since the drain drainage groove members 10, 11, 12 and the floor covering material 3 can be joined by a simple operation of simply applying and coating the edge 3a of the floor covering material 3 on top of it and comparing them. Even an unskilled worker can perform water-tight joining without causing poor bonding, and the edge 3a of the floor covering 3 is water-tight over a wide range over almost the entire upper surface of the tongue edge 1a. Therefore, excellent waterproofness can be exhibited. Further, since the joint interface between the tongue edge portion 1 a of the drain drainage groove members 10, 11, and 12 and the edge portion 3 a of the floor covering material 3 is covered with the edge portion 3 a of the floor covering material 3 and is not exposed, Even when applied to outdoor corridors or veranda floors exposed to light or wind and rain, deterioration of the bonding interface over time can be suppressed, and excellent waterproofness can be maintained over a long period of time.

  FIG. 6 is a plan view showing an embodiment of the floor covering structure of the present invention, and FIG. 7 is a partially enlarged sectional view taken along the line AA of FIG. In the floor covering structure shown in FIGS. 6 and 7, the drain drain groove member 10 and the floor covering material 3 are adjacent to both sides of the drain drain groove member 10 and adhered to a concrete floor base 5 in a common corridor with a floor adhesive. The edge 3a of the floor covering material 3 is superimposed on the upper surface of the tongue edge 1a to which the adhesive 4 has been applied, and is adhered and joined in a watertight manner, which is excellent as described above. Waterproofness is given. The gap between the side surface 1f of the groove member main body 1 of the drain drainage groove member 10 and the end surface of the floor covering material edge 3a is filled with a sealing agent 6 to further improve the waterproof property and clean the joint portion. It has been finished. In addition, a lid member 2 is attached to the concave groove portion 1d of the drain drainage groove member 10, and a drain hose connector 20 is attached to the drain hose connector 20, and a drain of the air conditioner is connected to the connection port 20a of the drain hose connector 20. When a hose (not shown) is inserted and connected, drain water discharged from the air conditioner flows through the concave groove portion 1d of the drain drain groove member 10 and is drained to the side groove 5a in the common hallway.

  As shown in FIG. 7, the joint portion (the tongue edge portion 1 a to which the floor covering material edge 3 a is joined) between the drain drainage groove member 10 and the floor covering material 3 and the floor base 5 corresponding to the both side vicinity portions thereof. On the corresponding surface, a ridge group consisting of ridges 7 of a plurality of linear adhesives for floors parallel to each other along the joint portion (tongue edge 1a) is formed, The joint portion and the portions in the vicinity of both sides are adhered to the corresponding surface of the floor foundation 5 by the convex strips of the adhesive. The ridge group consisting of the ridges 7 of the plurality of floor adhesives uses the comb irons 8 as shown in FIG. It is formed by applying straight along the tongue edge 1a.

  In addition, the surface of the floor base 5 other than the corresponding surface is formed with a plurality of strips of adhesive strips by the comb irons 8, and the floor covering 3 is formed by the convex strips. 5, but this ridge group is composed of curved ridges whose directions are free, and is joined like the ridge group formed on the corresponding surface of the floor foundation 5. It does not comprise a plurality of linear strips of convex adhesive strips 7 that are parallel to each other along the portion (tongue edge 1a).

  As described above, straight lines parallel to each other along the joint portion on the corresponding surface of the floor base 5 corresponding to the joint portion between the drain drainage groove member 10 and the floor covering material 3 and the portions near both sides thereof. A plurality of ridges 7 made of a plurality of adhesive adhesive ridges are formed, and the joints and portions near both sides thereof are adhered to the corresponding surface of the floor base 5 by the adhesive ridges. In the unlikely event that rainwater or the like may invade from the joint between the tongue edge 1a and the floor covering material edge 3a, each protrusion 7 of the adhesive protrusions enters the weir. There is an advantage that water can be prevented from spreading widely between the floor covering material 3 and the floor base 5. In that case, if a strip-shaped waterproof sheet is laid in advance on the corresponding surface of the floor base 5 and the convex strips of the adhesive are formed on the surface of the strip-shaped waterproof sheet, it is double waterproofed. It is possible to completely prevent intrusion.

  The convex strips of the floor adhesive have a height of 0.5 to 5 mm (the height of the convex strips 7 before the overlapping portions of the drain drain groove member 10 and the floor covering material 3 and the portions near both sides thereof are attached. In this embodiment, the width of the ridges 7 is 0.5 to 5 mm (in this embodiment, about 2 mm), and the interval between the ridges 7 is 0.5 to 6 mm (in this embodiment, about 3 mm). If it is formed in such a dimension, it is pressed at the time of sticking, and finally the height of the ridges 7 is 0.1 to 3 mm (in this embodiment, about 0.5 mm). The width of the ridges 7 is 0.5 to 5 mm (about 3 mm in this embodiment), and the interval between the ridges 7 is 0.5 to 6 mm (about 3 mm in this embodiment), so that each ridge 7 penetrates rainwater or the like. It will be able to fulfill the role of a water barrier to block diffusion. Accordingly, the comb irons 8 forming the ridge group of the present embodiment are formed by forming inverted V-shaped combs 8a in a horizontal line at intervals as shown in FIG. 10, and the height of the inverted V-shaped combs 8a. What set a to 2 mm, width c to 2 mm, and the mutual space | interval b of the comb is 3 mm is used.

  Note that the above-described comb iron is also used when a floor adhesive is applied to a surface other than the corresponding surface of the floor base 5 to form a free curved ridge group.

  The floor base 5 on which the floor covering structure of the present invention is constructed is not limited to the concrete floor base 5 described above, and a general floor base employed in a building such as a mortar floor base is used. Either is applicable. Further, as the floor covering material 3, an exterior soft vinyl chloride resin or olefin resin floor sheet laid on a balcony, veranda, corridor or the like is preferably used, and the floor sheet has a long sheet shape. However, it may be tiled.

  As floor adhesives (floor adhesives applied with a comb iron so as to form a group of ridges) for adhering the floor covering material 3 and the drain drainage groove member 10 to the floor base 5, urethane-based, epoxy Type, acrylic, modified silicone type curable floor adhesives are used, especially urethane type and epoxy type with excellent water resistance (two-component mixed type or one-component type such as moisture curable type) Are preferably used. In addition, a rubber-based floor adhesive or the like is also used.

  On the other hand, as the adhesive 4 for attaching the tongue edge portion 1a of the drain drainage groove member 10 and the edge portion of the floor covering material 3, any one of tetrahydrofuran (THF), methyl ethyl ketone (MEK), cyclohexane or the like alone or these A so-called “seam solution” comprising a mixture of the above (including a solvent alone or a mixture obtained by adding a soluble resin such as a vinyl chloride resin in a proportion of 10% by mass or less), or a vinyl chloride to the solvent alone or a mixture A so-called “dope cement” in which a soluble resin such as a resin is dissolved in an amount of about 10 (not including 10) to 50 mass%, or a known modified silicone-based or urethane-based adhesive is used. Such a sticking agent 4 may be applied by brushing on the upper surface of the tongue edge portion 1a when the viscosity is low, or may be applied by pouring out from a washing bottle, and when the viscosity is high, it may be spread with a trowel or the like. .

  Further, as the sealant 6 that fills the gap between the side surface 1f of the groove member main body 1 of the drain drainage groove member 10 and the end surface 3a of the floor covering material 3, epoxy-based, urethane-based, silicone-based, modified silicone A sealant such as a system is used. This gap may be welded with a resin welding rod. In this case, a thermoplastic resin welding rod having good fusion properties with the drain drain groove member 10 and the floor covering material 3 is used. Further, the above-mentioned dope cement or seam liquid may be filled. When the seam liquid is used, it is desirable that the gap between the side surface 1f and the end surface 3a of the floor covering material 3 is 0.5 mm or less. .

  The floor covering structure as described above has excellent water tightness at the joint between the drain drainage groove member 10 and the floor covering material 3, and is applied to an outdoor corridor or a floor floor of a veranda exposed to sunlight or wind and rain. However, deterioration over time of the bonding interface is suppressed, and excellent waterproofness can be maintained over a long period of time.

  FIG. 8 is a partially enlarged sectional view showing another embodiment of the floor covering structure of the present invention, and FIG. 9 is a sectional view of a drain drainage groove member 13 used in the floor covering structure. The drain drainage groove member 13 used in this floor covering structure is provided with a thin belt-like sheet 1j that is thinner and wider than the groove member main body 1 on the lower surface of the groove member main body 1, and has a thin tongue that protrudes on both the left and right sides of the groove member main body 1. The edge portions 1a and 1a are formed over the entire length of the groove member main body 1, and the groove member main body 1 is the same as the groove member main body 1 described above.

  The belt-like sheet 1j is a sheet made of a thermoplastic resin that is the same type or compatible with the groove member main body 1, and preferably has a thickness of about 0.2 to 2 mm (in the embodiment, 0.5 mm). The width of the belt-like sheet 1j is not particularly limited, but when it is provided on the lower surface of the groove member main body 1, the tongue edge portion 1a of about 5 to 30 mm is formed on the left and right sides or either one side of the groove member main body 1. A belt-like sheet 1j having a sheet width is preferable. Further, it is preferable to incline the upper surface of the side edge portion so that the side edge portion that becomes the tongue edge portion 1a of the belt-like sheet 1j gradually decreases as the thickness approaches the side end (tip). It is also preferable to form the above-described raised portion 1g on the upper surface or the lower surface of the side edge portion serving as the edge portion 1a in parallel with the side surface of the groove member body 1 over the entire length. And depending on the case, it is also preferable to form the groove | channel 1h which stores the solvent-type adhesive agent mentioned above in the upper surface of the side edge part used as this tongue edge part 1a.

  The floor covering structure shown in FIG. 8 has the drain drain groove formed by applying the adhesive 4 and adhering the drain drain groove member 13 and the floor covering material 3 to the floor base 5 with the floor adhesive. The edge portion 3a of the floor covering material 3 is overlapped on the tongue edge portion 1a of the member 13 and is watertightly bonded and joined, and the floor base 5 corresponding to the joint portion and the portions near both sides thereof is joined. On the corresponding surface, a ridge group consisting of the above-mentioned plurality of floor adhesive ridges 7 arranged in parallel with each other along the joint portion is formed. The joint portion and the portions near both sides thereof are attached to the corresponding surface of the floor base 5. Therefore, the floor covering structure shown in FIG. 8 is also excellent in the water tightness of the joint portion between the drain drainage groove member 13 and the floor covering material 3 in the same manner as the floor covering structure shown in FIGS. Even when it is applied to an outdoor corridor or floor floor such as a veranda exposed to light or wind and rain, deterioration of the joint interface over time can be suppressed, and excellent waterproofness can be maintained over a long period of time.

  In addition, although the strip | belt-shaped sheet | seat 1j of the drain drainage groove member 13 may stick together with the adhesive agent etc. to the lower surface of the groove member main body 1 previously, it applies an adhesive agent etc. in the middle of constructing a floor covering structure. The groove body 1 may be stacked on the belt-like sheet 1j so as to be integrated.
