Abstract

<P>PROBLEM TO BE SOLVED: To provide a joint structure and a joint construction method for a floor covering material securing sufficient water cut-off performance over a long period of time even if a joint of the floor covering material is exposed to sunlight or the like. <P>SOLUTION: The joint structure for the floor covering material 2 stuck to floor backing 1 with an adhesive 3 is structured to form projected strips 3a of the adhesive 3 on both sides of a joint 4 of the floor covering material 2 along the joint 4 over the whole length of the joint 4 and to block the joint 4 with a joint treating material 5. Even if the joint treating material 5 is degraded by the sunlight or the like to allow rainwater to infiltrate from the joint 5, the projected strips 3a of the adhesive formed on both sides along the joint 4 intercept the rainwater to prevent diffusion between the floor covering material 2 and floor backing 1. The projected strips 3a of the adhesive are covered with the floor covering material 2 so as not to be exposed to the sunlight. Consequently, the projected strips 3a of the adhesive are hardly degraded, and sufficient water cut-off performance can be maintained over the long period of time. <P>COPYRIGHT: (C)2010,JPO&INPIT

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

  FIG. 1 is a cross-sectional view showing a joint structure of a floor covering material according to an embodiment of the present invention, and FIG. 2 is a plan view showing a floor foundation on which an adhesive protrusion is formed before the floor covering material is adhered. is there.

  In FIG. 1, reference numeral 1 denotes a concrete floor base such as a veranda or a balcony, and floor covering materials 2 and 2 made of synthetic resin are attached to the surface of the floor base 1 with an adhesive 3. The adhesive 3 is applied to the floor base 1 so that a large number of protrusions 3a and 3b are formed at intervals by a comb iron 11 as shown in FIG.

  The ridges 3a of the adhesive 3 are linear ridges parallel to each other as shown in FIG. 2, and the ridges 3a are formed on both floor covering materials 2 as shown in FIGS. A plurality of strips are formed on both sides of the seam 4 along the seam 4 over the entire length of the seam 4. The other ridges 3b of the adhesive 3 are free-curved ridges as shown in FIG. 2, and the ridges 3b are the floor base except for the region where the above-mentioned ridges 3a are formed. 1 is formed on the surface. Both floor covering materials 2 and 2 are firmly attached to the floor 1 so as not to be peeled off by the protrusions 3a and 3b of these adhesives.

  In this embodiment, as shown in FIG. 2, the ridges 3c in the direction parallel to each edge are provided along the front edge and the rear edge of the floor base 1 (upper edge portion and lower edge portion in FIG. 2). Is formed. Furthermore, although not shown in figure, the protruding item | line 3c is formed in the direction parallel to the edge on the edge opposite to a joint. Although these ridges 3c may be omitted, it is preferable to form these ridges 3c in order to improve the water stoppage of the entire floor covering material 2. In FIG. 2, the ridges 3 a parallel to the seam and the ridges 3 c parallel to the edges are formed separately, but may be formed continuously over the entire edge of the floor covering 2.

  As shown in FIG. 1, notches 2a and 2a are formed by chamfering at the edge of the floor covering materials 2 and 2 on the joint 4 side, and the width of the upper portion of the joint 4 is expanded. The upper part of the joint 4 is closed with the joint treatment material 5.

  When the seam structure of the floor covering material as described above is used, even if the seam treatment material 5 that closes the seam 4 is deteriorated by sunlight or the like and rainwater or the like enters from the seam 4, the adhesive formed on both sides of the seam 4 Since the ridges 3a, 3a of the agent (the ridges on both sides closest to the joint) serve as a water blocking wall that dams rainwater, etc., rainwater, etc., flows between the floor coverings 2, 2 and the floor foundation 1. Diffusion can be prevented. And even if the ridges 3a, 3a on both sides closest to the seam 4 are partially damaged for some reason, rainwater etc. are blocked by the ridges on both sides closest to the second, so surely The water can be stopped. Further, the adhesive ridges 3a serving as the water blocking walls are not covered with the floor covering materials 2 and 2 and are not exposed to sunlight, and are not directly affected by the cold or warm air. It is difficult to maintain a sufficient water-stopping property over a long period of time.

  The floor foundation 1 is not limited to the concrete one described above, and any general floor foundation employed in buildings such as a mortar one can be applied. Moreover, as the floor covering material 2, a floor sheet made of soft vinyl chloride resin or polyolefin resin for exterior use laid on a balcony, veranda, corridor or the like is preferably used, and the floor sheet is in the form of a long sheet. However, it may be tiled.

  As the adhesive 3, curable adhesives such as urethane, epoxy, acrylic, and modified silicone are used. In particular, urethane and epoxy that have excellent water resistance (two-component mixed type or moisture curable type) Are preferably used. A rubber-based adhesive or the like is also used.

  As described above, the adhesive ridges 3a, 3b, and 3c are formed by scratching the adhesive reservoir with the comb iron 11 having a comb-shaped tip, and the floor covering material 2 is adhered thereto. The height of the front ridges 3a, 3b, 3c is 0.5 to 5 mm (about 2 mm in the present embodiment), the width is 0.5 to 5 mm (about 2 mm in the present embodiment), and the interval between the ridges is 0 It is desirable to form so that it may become 5-6 mm (about 3 mm in this embodiment). Since such ridges 3a, 3b, 3c adhere the floor covering material 2 in an uncured or semi-cured state, the floor covering material 2 is pressed and the height is 0.1 to 0.1. 3 mm (about 0.5 mm in the present embodiment), a width of 0.5 to 5 mm (about 3 mm in the present embodiment), and an interval between protrusions of 0.5 to 6 mm (about 3 mm in the present embodiment). As shown in FIG. 6, the comb iron 11 used in the present embodiment is formed by forming inverted V-shaped combs 11 a in a horizontal line at intervals, and the inverted V-shaped comb 11 a has a height a of 2 mm and a width. Since c is set to 2 mm and the mutual space b between the combs is set to 3 mm, the protrusions having a height of 2 mm, a width of 2 mm, and a mutual interval of 3 mm are formed as described above.

  The adhesive ridges 3a, 3b, and 3c may be formed by discharging the adhesive from an adhesive tube having a plurality of discharge holes at the tip or from the discharge port of the cartridge.

  Further, as the seam treatment material 5, an epoxy-based, urethane-based, silicone-based or modified silicone-based sealing material, a thermoplastic resin welding rod having a good fusion property with the floor covering material 2, or the like is preferably used. . When the seam 4 is closed with such a seam treatment material 5, the finish of the seam 4 becomes beautiful and the floor covering materials 2 and 2 from the seam 4 can be prevented from rolling up. In addition, since the double waterproof structure is formed by the joint treatment material 5 and the concave grooves 3a and 3a of the adhesive on both sides of the joint 4, the waterproofness (waterproofness) is further improved. In addition, the edge of the floor covering material 2 other than the joint may be water-tightly joined to the edge of the floor covering material 2 and the floor base 1 or the wall surface (not shown) with an end treatment agent (not shown). desirable.

  The seam structure of the floor covering material described above is constructed in the following manner according to the seam construction method of the present invention. First, the adhesive 3 is applied to the place where the joint 4 of the floor coverings 2 and 2 is to be formed on the floor base 1 with a constant width (comb iron width) 11 over the entire length of the planned joint. It is applied to form the above-mentioned linear adhesive ridges 3a on both sides of the planned seam along the planned seam. And the adhesive agent 3 is apply | coated to the surface of the floor foundation | substrate 1 except the formation area | region of this protrusion 3a with the comb iron 11, and the protrusion 3b of the free-curve-shaped adhesive agent mentioned above or the linear protrusion 3c is formed (it goes without saying that the adhesive ridge 3a may be formed after the adhesive ridge 3b or the linear ridge 3c is formed). Thereafter, the floor coverings 2 and 2 are stuck to the floor base 1 with the protruding strips 3a, 3b, and 3c of these adhesives interposed therebetween, and a joint 4 is formed at a predetermined location. When closed with the material 5, the above-mentioned floor covering material joint structure can be constructed with good workability.

  In this case, as described above, the adhesive ribs may be formed by discharging the adhesive from the discharge port of the adhesive tube or cartridge instead of the comb iron 11.

  FIG. 3 is a cross-sectional view showing a joint structure of a floor covering material according to another embodiment of the present invention.

  The seam structure of this floor covering material is the above-described figure except that the synthetic resin layer 6 is formed between the ridges located immediately below the joint 4 among the ridges 3a of the adhesive. It is comprised similarly to the 1 seam structure.

  The synthetic resin layer 6 is formed by injecting a seam solution (also called dope cement) in which a thermoplastic synthetic resin such as polyvinyl chloride is dissolved in a volatile solvent between the ridges 3a, or volatilizing the solvent. A layer formed by injecting and curing a liquid curable resin of a thermosetting type, a two-component curable type, or a moisture curable type. As the curable resin, urethane, epoxy, silicone, and modified silicone resins are preferably used. This synthetic resin layer 6 may be formed between all of the ridges 3a (when forming between all of the ridges 3a, before attaching the floor covering material 2 to the base 1, In addition, a seam solution or a curable resin is injected), or the space between the protrusions 3 a may be filled with the synthetic resin layer 6.

  The above-mentioned seam liquid or liquid curable resin for forming the synthetic resin layer 6 needs to enter the narrow gap between the ridges 3a and 3a and spread uniformly, so that the viscosity is 500 Pa · s or less. It is desirable. Injection of seam liquid or liquid curable resin can be easily performed using an injection tool having an injection nozzle at the tip, but if the viscosity of the seam liquid or liquid curable resin is too low, floor covering material Since it drops on the surface of 2 and soils the floor covering material 2, it is desirable to adjust the viscosity so that it does not easily sag.

  In the case of a seam solution in which a thermoplastic synthetic resin is dissolved in a solvent, the solvent can swell or dissolve the resin of the floor covering material 2 or the resin of the adhesive 3 as the solvent (for example, the floor covering material 2 is made of a vinyl chloride resin. If possible, use a solvent such as tetrahydrofuran, or a seam solution in which the same type of resin as the floor covering 2 or adhesive 3 is dissolved (for example, if the floor covering 2 is made of vinyl chloride resin, use vinyl chloride resin. When dissolved, the both sides of the joint 4 of the floor coverings 2 and 2, the back of the end of the floor coverings 2 and 2, and the surface of the adhesive protrusion 3 a are integrated with the synthetic resin layer 6. It is preferable because the water-stopping property is improved. Moreover, when using together the strip | belt-shaped waterproof sheet mentioned later, since a strip | belt-shaped waterproof sheet can also be integrated by using the solvent which can swell or melt | dissolve the resin of a strip-shaped waterproof sheet, it is still more preferable. In addition, when using a strip | belt-shaped waterproof sheet together, you may make it inject | pour only the solvent which swells or melt | dissolves the resin of a strip | belt-shaped waterproof sheet.

  When the synthetic resin layer 6 is formed between the ridges located immediately below the joint 4 among the ridges 3a of the adhesive, as in the joint structure shown in FIG. Even if a crack 1a occurs in the floor base 1 of the floor, the synthetic resin layer 6 can prevent rainwater or the like entering from the joint 4 from penetrating into the crack 1a or joint portion of the floor base 1, etc. There is an advantage that the waterstop is further improved. 3 shows a crack in a direction parallel to the seam. However, when a crack occurs in a direction crossing the seam, the ridge 3a and the ridge 3b communicate with each other through the crack. When rainwater or the like enters, rainwater diffuses between the floor covering material 2 and the base 1. Therefore, the formation of the synthetic resin layer 6 is particularly effective for cracks in the direction across such a joint.

  Since the other structure of this joint structure is the same as that of the joint structure of FIG. 1 mentioned above, the same code | symbol is attached | subjected to the same member in FIG. 3, and the overlapping description is abbreviate | omitted.

  The seam structure shown in FIG. 3 is an adhesive located immediately below the seam 4 by injecting seam liquid or the like from the seam 4 before the seam 4 is closed with the seam treatment material 5 in the seam construction method of the present invention described above. By forming the synthetic resin layer 6 between the ridges 3a, 3a, it is possible to construct with good workability. In addition, what is necessary is just to inject | pour a seam liquid before sticking the floor covering materials 2 and 2 when forming the synthetic resin layer 6 in all between the protrusions 3a.

  This belt-like waterproof sheet 7 is a belt-like sheet made of a synthetic resin such as a soft vinyl chloride resin, and has a width of 10 to 500 mm (100 mm in this embodiment) and a thickness of 0.1 to 3 mm (0.2 mm in this embodiment). In particular, those having a fiber reinforced layer (polyester resin, nylon resin, woven or nonwoven fabric of organic or inorganic fibers such as glass) as an intermediate layer (for example, tarpaulin tape) are used for strength and handling. From this point, it is preferably used. The belt-like waterproof sheet 7 may be fixed to the floor base 1 with an adhesive or adhered with an adhesive, or may not be fixed.

  As shown in the joint structure shown in FIG. 4, a belt-like waterproof sheet 7 is attached to the floor base 1 along the joint 4 of the floor coverings 2, 2, and an adhesive is formed on the belt-like waterproof sheet 7. 3 ridges 3a are formed, this water-resistant waterproof sheet 7 can prevent rainwater or the like entering from the joint 4 from penetrating into cracks or joints of the floor substrate 1, thereby further improving the water-stopping property. There are advantages to doing.

  Since the other structure of this joint structure is the same as that of the joint structure of FIG. 1 mentioned above, the same code | symbol is attached | subjected to the same member in FIG. 4, and the overlapping description is abbreviate | omitted.
