Description

  The present invention relates to a seam structure and a seam construction method for a floor covering material, and more particularly to a seam structure and a seam construction method for a floor covering material that can ensure a sufficient water-stopping property over a long period of time.

  Conventionally, as a method for treating a seam between floor covering materials adhered to floor bases such as common corridors, verandas, and balconies of apartment buildings, a method of injecting a curable sealing material into the seam or resin welding of the seam is available. It is well known.

  A bonding resin layer is formed by applying a liquid resin made of a thermoplastic resin on the lower ground corresponding to the joint line where the edges of the adjacent waterproof sheets are abutted against each other, and the bonding film layer is waterproofed. There has also been proposed a construction method of a waterproof sheet in which the edge portion of the sheet is joined and integrated by thermal fusion, solvent welding, or adhesive bonding (Patent Document 1).

JP 2005-146633 A

  However, in the known seam treatment method, when the seam treatment material such as the seam sealing material or welding resin deteriorates due to sunlight or a temperature change, the water stoppage is lowered and rainwater or the like is removed from the seam of the floor covering material. There was a problem of penetration.

  On the other hand, in the construction method of the waterproof sheet of Patent Document 1, since the bonding film layer is covered with the edge portion of the waterproof sheet, the bonding film layer and the waterproof sheet are not deteriorated early by sunlight. Since it is not easy to heat-weld or solvent-weld or adhesive-bond the edge part of the entire surface in a water-tight manner, it is easy to make a partially-joined part or a water intrusion path, and to the bonding film layer. Since there is a possibility that defects such as pinholes may occur, the waterproofness (waterproofness) is hardly perfect.

  The present invention has been made under the circumstances described above, and the problem to be solved is that even if the seam treatment material that closes the seam of the floor covering material is deteriorated, sufficient waterproofness (waterproofness) is provided over a long period of time. It is to provide a seam structure and a seam construction method for a floor covering material that can be secured.

In order to solve the above problems, a floor covering material joint structure according to claim 1 of the present invention is a floor covering material seam structure bonded to a floor base with a floor adhesive, and the floor covering material seam is The floor surface of the floor under the seam is covered with a plurality of strips of the floor adhesive that are parallel to each other along the seam over the entire length of the seam.

Such curved projections are multiple conditions increments formed floor covering material is bonded, it is characterized in.

In the joint structure of the floor covering material according to claim 1 of the present invention, a part of the ridges of the ridge group of the floor adhesive is located on one side of the seam, and the remaining ridges are on the opposite side of the seam. It is good to set it as the structure which is located in and does not cross | intersect the said protruding item | line with the said joint .
Further, the joint structure of the floor covering material according to claim 3 of the present invention is a joint structure of the floor covering material bonded to the floor base with the floor adhesive, and the joint of the floor covering material is closed with the seam treatment material. The floor base surface below the seam is formed with a group of ridges composed of a plurality of ridges of the floor adhesive that are parallel to each other along the seam over the entire length of the seam. And at least both ends of the ridge group of the floor adhesive are located on both sides of the seam without intersecting the seam, and at least all or one of the remaining portions excluding the ridges on both ends. A strip extending over the entire length of the seam between the seam and the edge of the floor covering material on both sides of the seam and the convex group of the floor adhesive. Are provided, and the surface of the strip and the back surface of the edge of the floor covering are attached with an adhesive, Rear face underfloor surface of serial strip is bonded by convex groups of the floor adhesive, it is characterized in.
And the seam structure of the floor covering material according to claim 4 of the present invention is a floor covering material seam structure bonded to the floor base with a floor adhesive, and the seam of the floor covering material is closed with the seam treatment material. The floor base surface below the seam is formed with a group of ridges composed of a plurality of ridges of the floor adhesive that are parallel to each other along the seam over the entire length of the seam. A strip extending over the entire length of the seam is provided between the seam and the edge of the floor covering material on both sides of the seam and the convex strips of the floor adhesive, and the strip The back surface of the edge of the floor covering material and the back surface of the floor covering material are pasted with a sticking agent, and the back surface and the floor base surface of the belt-like body are bonded with the convex strips of the floor adhesive , The width is 20 to 500 mm, the width of the convex strip group of the floor adhesive is 30 to 600 mm, and the floor adhesive Convex groups are formed in width wider than the width of the strip, it is characterized in.

In addition, the floor covering material construction method according to claim 5 of the present invention is a seam construction method for a floor covering material that is bonded to a floor base with a floor adhesive, and a floor covering material seam on the floor base is formed. A step of forming a ridge group consisting of ridges of a plurality of floor adhesives juxtaposed along the planned seam over the entire length of the planned seam on the surface of the planned site, and the above The process of superimposing a strip covering the entire length of the planned seam on the ridges of the floor adhesive, and the floor covering material joints are planned by superimposing the edges of both floor coverings on the strip A step of forming the portions of the floor covering material, a step of rolling up the edge portions of both floor covering materials, and applying a sticking agent to the surface of the belt-like body, and the edge portions of both of the raised floor covering materials The part is again overlaid on the strip and pressed from above, and the seams of both floor coverings are closed with the seam treatment material. A step of forming a plurality of free curved ridges of the floor adhesive on the floor base surface other than the floor base surface on which the convex strips of the floor adhesive are formed, and the floor it is characterized in that comprises a step of free curved projections of use adhesive to bond the floor covering to multiple conditions increments formed underfloor surface.

Since the seam structure of the floor covering material of the present invention is a structure that can exhibit a triple waterproof (waterproof) function as described below, rainwater and the like penetrate between the floor covering material and the floor covering material and the floor base. , It can be surely prevented from diffusing.
That is, since the seam of the floor covering material is blocked by the seam treatment material, intrusion of rainwater or the like from the seam is first prevented by the seam treatment material closing the seam.
And even if the seam treatment material deteriorates over time due to direct sunlight or temperature changes, and rainwater enters from the seam of the floor covering material, the seam treatment material will be on the back surface of the edge of the floor covering material on both sides of the seam. The band-like body that is stuck with the sticking agent and covers the entire length of the joint prevents permeation and diffusion of rainwater and the like between the floor covering material on both sides of the joint and the floor base. In particular, this strip is bonded to the floor base with a convex strip group of floor adhesive, and the adhesive is applied in a state where the surface of the strip is strongly pressed against the back surface of the edge of the floor covering material by the convex strip group. Therefore, the surface of the band-like body is formed with a linear sticking area having high sticking strength and adhesion corresponding to the ridge group, and the linear sticking area is used to infiltrate rainwater, etc. Penetration and diffusion to both sides of the seam are reliably prevented. In addition, the strip and the adhesive are covered with the floor covering material and do not receive direct sunlight, and are not directly affected by the cold or warm air, so that they are not easily deteriorated over time, and therefore, the above-mentioned over a long period of time. The waterproofing (water-stopping) effect will last.
In addition, even if the above band-like body deteriorates and cracks, tears, etc. occur and rainwater etc. leaks to the floor underside of the band-like body, the adhesive for floor bonding the band-like body to the floor base Since each ridge of the ridge group of agent acts as a water blocking wall to prevent rainwater etc. from penetrating and diffusing to both sides of the seam, both sides of the joint such as rainwater by this ridge group of floor adhesive Penetration into and diffusion will be prevented. And the waterproofing (water-stopping) effect by the convex stripe group of this floor adhesive is also maintained for a long period of time because the convex stripe group is unlikely to be deteriorated by sunlight or cold / warm air.
Thus, the seam structure of the floor covering material of the present invention includes a seam treatment material that closes the seam, a belt-like body that is stuck to the back surface of the edge of the floor covering material on both sides of the seam, and the belt-like shape. Since it has a structure that can provide triple waterproofing (water-stopping) function by the convex strips of floor adhesive that adheres the body to the floor ground, rainwater between the floor covering material and the floor covering material And the like can be reliably prevented from penetrating and diffusing.

  The joint structure of the floor covering material of the present invention that exhibits the excellent waterproofing effect as described above can be constructed with good workability by the above-described seam construction method of the floor covering material of the present invention. In particular, the seam construction method of the present invention includes a step of overlying the edge portions of both floor covering materials rolled up again on the band-like body and pressing from above, and by this pressing step, The back surface of the strip and the floor base surface are firmly bonded with the convex strips of floor adhesive, and the surface of the strip and the back of the edge of the floor covering are formed with a sticking agent. However, since it can stick firmly and watertightly, the waterproofness of a joint can be improved further.

  Further, in the joint structure of the present invention, some of the ridges of the ridge group of the floor adhesive are located on one side of the seam, and the remaining ridges are located on the opposite side of the seam. In the structure that does not cross the line, the linear paste of the adhesive that sticks the surface of the strip and the back of the edge of the floor covering material corresponding to the convex stripes of the floor adhesive In the landing area, part of the linear part is located on one side of the seam, the remaining linear part is located on the opposite side of the seam, and no linear part intersects the seam. Diffusion of rainwater or the like that has infiltrated onto the belt from the seam due to deterioration of the seam, etc., is ensured by a part of the wire located on one side of the seam and the other wire located on the opposite side Will be blocked. And the diffusion to both sides of rainwater and the like that has entered the lower side of the band due to aging degradation of the band is located on the opposite side of some convex stripes of the floor adhesive located on one side of the seam The remaining ridges will surely prevent them.

On the other hand, as in the seam structure according to claim 3 of the present invention, at least both side ends of the projections of the convex groups of the floor adhesive located on opposite sides of the seam without intersecting the seam, convex at least two side The structure in which all or a part of the remaining ridges excluding the ridges intersects the joints corresponds to the ridges of the floor adhesive, and the surface of the strip and the edge of the floor covering material. The linear sticking area of the sticking agent for sticking the back of the edge part is also located on both sides of the seam without at least the linear parts on both side edges intersecting the seam, and at least the linear parts on both side edges are excluded. Since all or some of the remaining linear portions intersect the seam, diffusion of rainwater or the like that has entered the belt from the seam due to deterioration of the seam treatment material or the like on both sides of the seam is caused. Will be reliably prevented by the linear portions at least on both sides of the linear sticking area located on both sides of the And, diffusion of rainwater that has entered the lower side of the band due to aging deterioration of the band and the like is reliably prevented by the convex strips on at least both sides of the floor adhesive located on both sides of the seam. Will be.
Further, as described above, all of the remaining ridges except for the ridges on both side ends of the floor adhesive intersect with the seam. Compared to a configuration that does not intersect the seam, it is not necessary to form the convex strips of the floor adhesive so as to be exactly parallel to the joint, so that the convex strips can be easily formed. it can.

Further, as in the joint structure according to claim 4 of the present invention, the width of the belt-shaped body is 20 to 500 mm, the width of the convex strip group of the floor adhesive is 30 to 600 mm, and the floor adhesive In the case where the ridge group is formed with a width wider than the width of the band-like body, in addition to the above effect, the ridge group and the band-like body are slightly inclined with respect to the seam, or slightly on one side of the seam. Even if it is displaced, the waterproof (water stop) effect can be surely exhibited with a margin.

It is a top view which shows one Embodiment of the joint structure of the floor covering material which concerns on this invention. It is an AA line expanded sectional view of FIG. It is a top view which shows an example of the application | coating form of the floor adhesive in a floor foundation. It is explanatory drawing about the convex stripe group of the adhesive agent for floors. It is an enlarged plan view of the convex stripe group end part of the floor adhesive provided with the blocking part. It is explanatory drawing explaining one Embodiment of the seam construction method of the floor covering material which concerns on this invention in order of a process. It is explanatory drawing of a comb eye.

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

  FIG. 1 is a plan view of a joint structure of a floor covering according to an embodiment of the present invention, FIG. 2 is an enlarged sectional view taken along line AA of FIG. 1 (cross-sectional view of the joint structure), and 1 is common Concrete floors such as corridors, verandas, and balconies are shown. Floor coverings 2 and 2 made of synthetic resin are attached to the floor base 1 with a floor adhesive 3. The seams 4 of the floor covering materials 2 and 2 adjacent to each other are formed in a V-groove shape and are watertightly closed by the seam treatment material 5, and the end surfaces other than the seams of the floor covering material 2 are sealing materials. 6 is hermetically sealed.

  As shown in FIG. 2 and FIG. 3, a plurality of floor adhesive ridges 3 a are arranged on the surface of the floor base 1 below the joint 4 along the joint 4 along the joint 4 over the entire length of the joint 4. Convex ridge group 30a which consists of is formed. Each ridge 3a is ideally straight, but may be slightly meandered. As shown in FIG. 3 and FIG. 4A, this floor adhesive ridge group 30 a is formed in parallel along the seam 4 so that none of the ridges 3 a obliquely intersect the seam 4. Further, a part of the ridges 3a of the ridge group 30a is located on one side of the joint, and the remaining ridges 3a are located on the opposite side of the joint. In the ridge group 30a of this embodiment, the number of the ridges 3a located on the opposite side to the number of the ridges 3a located on one side of the joint 4 is the same, and the joint 4 is on the center line in the width direction of the ridge group 30a. However, the number of the ridges 3a located on both sides of the joint 4 is slightly different so that the joint 4 is slightly displaced to one side of the center line in the width direction of the ridge group 30a. May be.

Further, as shown in FIG. 4 (b), the convex line group 30 a of the floor adhesive is located on both sides of the seam 4 so that at least the convex lines 3 a on both side ends do not obliquely intersect the seam 4. It may be formed in a slightly oblique direction along the joint 4 so that all or a part of the remaining protrusions 3a excluding the end protrusion 3a obliquely intersects the joint 4.
However, as shown in FIG. 4C, the ridge group 30 a should not be formed obliquely with respect to the joint 4 so that all the ridges 3 a of the ridge group 30 a obliquely intersect the joint 4. If formed obliquely in this way, as will be described later, it is impossible to prevent the rainwater or the like that has entered from the vicinity of both ends of the seam 4 from penetrating and diffusing to both sides of the seam 4 by the ridges 3a at the both ends. This is because the objective cannot be achieved sufficiently.

The above-mentioned floor adhesive ridge group 30 a is applied to the surface of the floor base 1 below the joint 4 using the comb iron 10 as shown in FIG. 7 along the joint 4. However, it may be formed, for example, by discharging the adhesive for floors from the discharge tube of the adhesive tube having a plurality of discharge holes at the tip or the cartridge.
The floor adhesive 3 applied to the surface of the floor base 1 other than the floor base surface below the joint 4 is also applied with the same combing iron 10 and the floor adhesive 3 has a free curve. A plurality of convex ridges are formed.

  As shown in FIGS. 1 and 2, the joint 4 and the edge portions 2a and 2a of the floor coverings 2 and 2 on both sides of the joint 4 and the convex strip group 30a of the floor adhesive are connected to the joint 4. A strip 7 made of synthetic resin is provided over the entire length, and the front surface of the strip 7 and the back surfaces of the edge portions 2a and 2a of the floor coverings 2 and 2 are adhered with an adhesive 8. And the back surface of this strip | belt-shaped body 7 and the floor foundation | substrate 1 surface are adhere | attached by the convex strip group 30a of the adhesive agent for floors. When the back surface of the belt-like body 7 is bonded to the floor base 1 in a state where the back surface of the belt-like body 7 is supported by the respective convex stripes 3a of the floor adhesive group 30a, Since the surface is stuck in a state of being pressed against the back surfaces of the edge portions 2a and 2a of the floor coverings 2 and 2 through the sticking agent 8, the surface of the strip 7 has a protruding line. Corresponding to each ridge 3a of the group 30a, a linear sticking region of the sticking agent 8 having high sticking strength and adhesiveness is formed. In FIG. 2, the part applicable to the linear sticking area | region of this sticking agent 8 is painted black, and is shown typically.

  The width of the belt-like body 7 and the width of the ridge group 30a of the floor adhesive are not particularly limited, but rainwater or the like that has entered from the joint 4 penetrates and diffuses between the floor coverings 2 and 2 on both sides of the joint and the floor base 1. In order to prevent this from occurring with margin, the width of the belt-like body 7 is set to 20 to 500 mm, the width of the convex strip group 30a of the floor adhesive is set to 30 to 600 mm, and the convex strip group 30a of the floor adhesive is striped. It is desirable to form with a width wider than the width of the body 7.

In the case of the seam structure of the floor covering material as described above, since the seam 4 of the floor covering materials 2 and 2 is closed by the seam treatment material 5, the infiltration of rainwater or the like from the seam 4 is first performed by This is prevented by the seam treatment material 5 that is blocked.
And even if the seam treatment material 5 deteriorates with time due to direct sunlight or temperature change, and rainwater or the like enters the seam 4 of the floor coverings 2 and 2, the floor covering material on both sides of the seam 4 is used. The band 7 adhered to the back surfaces of the edge portions 2a, 2a with the adhesive 8 prevents permeation and diffusion of rainwater or the like between the floor coverings 2, 2 and the floor base 1 on both sides of the joint 4. Will be. In that case, the surface of the belt-like body 7 is firmly adhered to the back surface of the floor covering material edge portions 2a and 2a on both sides of the joint 4 by the linear adhesion region of the adhesive 8 described above. Therefore, the penetration and diffusion of rainwater and the like to both sides of the joint 4 are surely prevented.
Further, even when the strip 7 is deteriorated to cause cracks and the like, and rainwater or the like leaks to the floor base 1 below the strip 7, the strip 7 is bonded to the floor base 1. Each of the ridges 3a of the adhesive ridge group 30a serves as a water blocking wall for blocking rainwater or the like from penetrating and diffusing rainwater or the like on both sides of the joint 4. Infiltration and diffusion of rainwater and the like to both sides of the joint 4 are prevented.
The seam structure of this floor covering material is a belt-like material adhered to the back surface of the seam treatment material 5 for closing the seam 4 and the floor covering material edge portions 2a, 2a on both sides of the seam 4 as described above. Since the body 7 and the convex strips 30a of the floor adhesive that bonds the strip 7 to the floor 1 have a triple waterproof (waterproof) function, the floor coverings 2, 2 Thus, it is possible to reliably prevent rainwater and the like from penetrating and diffusing between the floor coverings 2 and 2 and the floor base 1 from the joint 4. Moreover, the strips 7, the adhesive 8, and the convex strips 30 a of the floor adhesive are covered with the floor coverings 2, 2, etc., and may receive direct sunlight or be directly affected by the warm and warm air. Therefore, the above-mentioned waterproofing (water-stopping) action can be continuously exhibited over a long period of time.

  As shown in FIG. 4 (a), the convex strip group 30a of the floor adhesive in the floor covering material joint structure has a portion of the convex strips 3a located on one side of the joint 4, and the remaining convex strips 3a Since it is located on the opposite side of the joint 4 and formed so that none of the ridges 3a intersect the joint 4, the surface of the strip 7 and the floor corresponding to the ridge group 30a of the floor adhesive As for the said linear sticking area | region of the sticking agent 8 which sticks the back surface of the edge parts 2a and 2a of the coating | covering materials 2 and 2, a part of linear part is located in the one side of the joint 4, and the remaining linear form The part is located on the opposite side of the seam 4, and none of the linear parts intersects the seam 4, and the remaining part located on the opposite side of some of the linear parts located on one side of the seam 4 By the linear portion, it is possible to reliably prevent diffusion of rainwater or the like entering the band 7 from the joint 4 to both sides of the band 7. And the diffusion to the both sides of the rainwater etc. which permeates the lower side of the belt-like body 7 due to the aging deterioration of the belt-like body 7 is opposite to some convex strips 3a of the floor adhesive located on one side of the joint 4 The remaining ridges 3a located on the side can be reliably blocked.

  On the other hand, as shown in FIG. 4 (b), at least the side ridges 3a of the floor adhesive ridge group 3a are positioned on both sides of the seam 4 without intersecting the seam 4, and at least both side ends. When the ridge group 30a is formed so that all or a part of the remaining ridges 3a excluding the ridges 3a intersect the seam 4, this corresponds to the ridge group 30a of the floor adhesive. In addition, the linear part of the adhesive 8 for adhering the surface of the belt-like body 7 and the back surfaces of the edge portions 2a, 2a of the floor coverings 2, 2 also has a seam 4 at least at the linear parts at both ends. Both sides of the seam 4 are located on both sides of the seam 4 without crossing the line, and at least all of the remaining linear parts except for the linear parts on both ends intersect the seam 4. Both sides of the strip 7 such as rain water that infiltrates from the joint 4 onto the strip 7 by the linear portions located at both ends on both sides It can be a diffusion reliably prevented. And the diffusion to the both sides of the rainwater etc. which permeates the lower side of the belt-like body 7 with the aging deterioration of the belt-like body 7 is located on both sides of the joint 4. Can be surely prevented.

  The floor foundation 1 in the joint structure of the floor covering material described above is not limited to the concrete floor foundation described above, and any general floor foundation employed in a building such as a mortar floor foundation may be used. Applicable. Moreover, as the floor covering material 2, 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.

  Curing type floor adhesives such as urethane, epoxy, acrylic, and modified silicone are used as the floor adhesive 3 for adhering the floor covering 2 and the strip 7 to the floor base 1, 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. In addition, a rubber-based floor adhesive or the like is also used.

  The convex strip group 30a of the floor adhesive formed on the surface of the floor base 1 below the joint 4 has a height of the convex strip 3a of 0.5 to 5 mm before the strips 7 are laminated and bonded (this embodiment). In this embodiment, the width of the ridges 3a is 0.5 to 5 mm (in this embodiment, about 2 mm), and the interval between the ridges 3a is 0.5 to 6 mm (in this embodiment, about 3 mm). Desirably, when it is formed with such dimensions, it is pressed when the strip 7 is bonded, and finally the height of the protrusion 3a is 0.1 to 3 mm (in this embodiment, about 0.5 mm). ), The width of the ridges 3a is 0.5 to 5 mm (about 3 mm in the present embodiment), and the interval between the ridges is 0.5 to 6 mm (about 3 mm in the present embodiment). It will be able to fulfill the role of a water blocking wall that blocks the penetration and diffusion of both sides of the seam.

  As described above, the convex group 30a of the floor adhesive of the present embodiment is obtained by applying the floor adhesive 3 to the surface of the floor base 1 below the joint 4 using the comb iron 10 shown in FIG. The comb iron 10 is formed by forming inverted V-shaped combs 10a in a horizontal line at intervals as shown in the figure, and the height V of the inverted V-shaped comb 10a is 2 mm and the width c. Is set to 2 mm, and the inter-interval b of the comb is set to 3 mm. Thus, the protrusions 3a of the formed protrusion group 30a have a height of 2 mm, a width of 2 mm, and a mutual interval of 3 mm.

  In addition, the floor adhesive 3 applied to the surface of the floor base 1 other than the floor base surface below the joint 4 is also applied with a comb iron 10 to form a plurality of free curved ridges as described above. The height, width, mutual interval, etc. of each ridge are the same as those of the ridge 3a of the ridge group 30a.

  In the joint structure of the present embodiment, the length of the convex strip group 30a of the floor adhesive and the length of the joint 4 are the same, but the length of the convex strip group 30a and the length of the joint 4 need to be the same. Is not necessarily. For example, in order to improve the waterproofness (waterproofness) of the front edge and the rear edge of the floor covering material 2, a plurality of ridges of the floor adhesive 3 are formed along the front edge and the rear edge of the floor base 1. When the floor adhesive 3 is applied with a comb iron 10 so as to be formed, the length of the convex strip group 30a of the floor adhesive is along the front edge and the rear edge of the floor foundation 1. The length of the seam 4 is shorter than the length of the joint 4 by the amount of the protrusions of the floor adhesive 3 formed, but that may be sufficient.

  Moreover, as shown in FIG. 5, the strip-shaped water stop member 9 is provided in the direction crossing the ridge group 30a at the end of the ridge group 30a of the floor adhesive, and the ridges 3a of the ridge group 30a are mutually connected. It is desirable to close the end portions of the respective groove portions 3b, or to fill and close the end portions of the respective groove portions 3b of the ridge group 30a with an adhesive or a sticking agent instead of the water-stopping member 9. When the end portions of the groove portions 3b of the ridge group 30a are closed in this way, even if the sealing material 6 that seals the end surfaces of the front and rear edges of the floor covering material 2 is deteriorated and damaged, the groove portions of the ridge group 30a. There is an advantage that rain water and the like can be prevented from entering 3b.

  As the band-like body 7 stacked on the convex strip group 30a of the floor adhesive, the belt-like body 7 is made of a synthetic resin that is the same as or compatible with the floor covering 2, or is welded to the floor covering 2 with a solvent or an adhesive. What is made of synthetic resin that can be bonded or is used, for example, when the floor covering material 2 is a floor covering material made of a soft vinyl chloride resin, a belt-like body mainly composed of vinyl chloride resin is suitable, In particular, a belt-like body made of a soft vinyl chloride resin is preferably used because of handling.

  Such a strip 7 may be a single layer or a laminate, for example, a layer in which a reinforcing fiber layer made of resin fibers or glass fibers is laminated as an intermediate layer or the lowermost layer for reinforcement, or a metal thin plate as an intermediate layer or the lowermost layer. A laminate of these is also preferably used. In particular, the belt-like body 7 in which the latter thin metal plates are laminated has an improved strength, and the belt-like body 7 is accidentally cut when the joint 4 of the floor coverings 2 and 2 is cut into a V-groove shape. There is an advantage that can be prevented by a metal thin plate. Further, a belt-like body 7 made of a laminate in which the uppermost layer and the lower layer thereof are colored in different colors is also preferably used. In such a belt-like body 7, the joint 4 of the floor covering materials 2 and 2 is formed into a V-groove shape. If the surface of the band-like body 7 is cut off by mistake when cutting, the different colors of the lower layer are visually recognized, and it is immediately known that the band-like body 7 has been damaged, so that the band-like body 7 can be repaired or replaced with a new one. There is an advantage that measures can be taken.

  As described above, the width of the band-like body 7 is preferably about 20 to 500 mm so that the waterproof effect can be exerted with a sufficient margin, and the thickness is preferably about 0.1 to 3 mm. The belt-like body 7 thinner than 0.1 mm may be perforated with hot air when the seam 4 is welded with hot air using a seam treatment material 5 such as a resin welding rod, for example, while being thicker than 3 mm. In addition to the high cost and poor handleability, the belt-like body 7 is unsatisfactory in appearance because the swells of the edge portions 2a and 2a of the floor coverings 2 and 2 on both sides of the joint 4 are conspicuous. A more preferable thickness of the strip 7 is about 0.3 to 1 mm.

  As the adhesive 8 for adhering the surface of the band 7 and the back surfaces of the edge portions 2a, 2a of the floor coverings 2, 2 on both sides of the joint 4, any of tetrahydrofuran (THF), methyl ethyl ketone (MEK), cyclohexane, etc. A so-called “seam solution” (single or a mixture thereof, including a solvent or a mixture of a soluble resin such as a vinyl chloride resin added to 10% by mass or less), or a solvent or a mixture of these solvents. A so-called “dope cement” in which a soluble resin such as a vinyl resin is dissolved in an amount of 10 (not including 10) to 50% by mass, or a known modified silicon-based or urethane-based adhesive is used. Such a sticking agent 8 may be applied to the surface of the belt-like body 7 with a brush when it has a low viscosity, or may be applied by pouring out from a washing bottle, and may be spread with a trowel or the like when the viscosity is high.

  The seam 4 of this embodiment is formed by cutting the end surfaces of the floor covering materials 2 and 2 on both sides into a V-groove shape, and filling the V-groove seam 4 with the seam treatment material 5 and closing it. Alternatively, the end surfaces of the floor covering materials 2 and 2 may be abutted without being cut to form the seam 4, and the seam 4 may be welded and closed using a solvent as a seam treatment material.

As the seam treatment material 5 filled in the seam 4, sealing materials such as epoxy-based, urethane-based, silicone-based, and modified silicone-based materials, and thermoplastic resin welding rods that have good fusibility with the floor covering material 2 are preferable. used. Further, as the seam treatment material for welding the seam 4, the above-mentioned seam solution, dope cement or the like is preferably used.
When the seam 4 is closed with these seam treatment materials 5, the finish of the seam 4 becomes beautiful and prevents rainwater from entering the seam 4 and the floor coverings 2 and 2 from the seam 4 from being rolled up. can do.

  Next, with reference to FIG. 6, an embodiment of the floor covering material joint method according to the present invention will be described in the order of steps.

As shown in FIG. 6 (a), in the first floor adhesive application step, on the surface of the place where the seam of the floor covering material in the floor base 1 is to be formed, the planned seam over the entire length of the planned seam. A plurality of strips 30a are formed of a plurality of strips of floor adhesive that are arranged in parallel with each other at intervals. As described above, the floor adhesive group 30a of the floor adhesive can be easily formed by using the comb iron 10 shown in FIG. 7 and applying the floor adhesive straight along the planned seam. be able to.
When forming the ridge group 30a of the floor adhesive, as shown in FIG. 4A, a part of the ridges 3a of the ridge group 30a is located on one side of the planned joint 4, and the remaining ridges are formed. 3a may be located on the opposite side of the planned seam 4, and the convex line group 30a may be formed to coincide with the direction of the seam 4 so that none of the convex lines 3a obliquely intersect the planned seam 4. As shown in FIG. 4 (b), at least the protruding strips 3a on both side ends are located on both sides of the planned joint 4 without obliquely intersecting the planned joint 4, and at least the protruding strips 3a on both side ends are removed. The ridge group 30a may be formed in a slightly oblique direction along the planned seam 4 so that all or a part of the remaining ridges 3a obliquely intersect the planned seam 4.

  Although not shown in FIG. 6, the floor adhesive 3 is applied to the floor base 1 other than the ridge group 30a. The step of applying the floor adhesive 3 to the floor base 1 may be performed in any step. For example, when the floor adhesive 3 is applied at the time of forming the ridge group 30a, the application work can be performed at a time, so that the work efficiency is high. Moreover, since it will not disturb | disturb during the other operation | work, if the strip | belt-shaped body 7 mentioned later is performed after the process of superimposing on the protruding strip group 30a, the protruding strip 3a of the formed protruding strip group 30a is not disturbed, this is also preferable. Furthermore, before forming the ridge group 30a, it may be applied to the floor base 1 leaving the edge portions 2a and 2a, and the floor coverings 2 and 2 may be bonded to the floor base 1. In this case, the edge portions 2a, 2a of the floor covering material that is not bonded may be rolled up, and the convex strip group 30a of the floor adhesive may be formed at the joint formation scheduled portion of the floor base 1. This is also preferable because the operator can work on the floor covering materials 2 and 2 that have been bonded. In addition, after the seam 4 is closed with the seam treatment material 5, the floor covering materials 2 and 2 other than the edge portions 2a and 2a can be rolled up.

  When the formation of the convex group 30a of the floor adhesive is finished, as shown in FIG. 6 (b), the strip covering the entire length of the planned seam is formed on the convex group 30a of the floor adhesive in the next step. Stack 7 along the planned seam. At this time, it is desirable that the strips 7 are overlapped so as not to protrude from both sides of the ridge group 30a.

  Then, in the next step, as shown in FIG. 6 (c), the edge portions 2 a and 2 a of both floor covering materials 2 and 2 are overlapped on the strip 7, The seam 4 is formed at a predetermined location (Note that the seam 4 is formed in the seam 4 if the ends of the edge portions 2a and 2a of both floor coverings 2 and 2 are previously overlapped and cut with a cutter. It can be easily adjusted neatly without creating a large gap). In this embodiment, the V-grooving operation is performed by further cutting the abutting end surfaces of both floor covering materials 2 and 2 obliquely to form the V-groove joint 4, but this V-grooving operation is omitted. May be. When this V grooving operation is performed, it is confirmed whether or not the band 7 is accidentally damaged. If it is found that the band 7 is damaged, the damaged portion is repaired or a new one is repaired. Replace with a strip.

  When the formation of the seam 4 is finished, in the next step, as shown in FIG. 6 (d), the edge portions 2a and 2a of both floor covering materials 2 and 2 are rolled up and adhered to the surface of the belt-like body 7. Agent 8 is applied. Application of the sticking material 8 may be performed by a known means depending on the properties of the sticking agent 8, such as solid coating with a brush as described above. In addition, application | coating of the adhesive 8 to the surface of the strip | belt-shaped body 7 can also be performed just before forming the joint 4 by overlapping the edge parts 2a and 2a on the strip | belt-shaped body 7. FIG. In this case, it is not necessary to roll up the edge portions 2a and 2a and apply the adhesive 8 and man-hours can be saved.

  When the application of the adhesive 8 is finished, in the next step, as shown in FIG. 6 (e), the edge portions 2a and 2a of both the floor coverings 2 and 2 that have been rolled up are again formed on the belt-like body 7. The upper surface of the belt 7 is pressed with a rolling roller 11 and the like, and the surface of the strip 7 and the back surfaces of the edge portions 2a and 2a of the floor covering material are pasted with the adhesive 8 and the strip 7 The back surface and the surface of the floor base 1 are bonded with a convex strip group 30a of a floor adhesive. As described above, when the contact is made while pressing with the rolling roller 11 or the like as described above, the surface of the support portion of the strip 7 supported by each protrusion 3a of the protrusion group 30a is the adhesive. 8 is attached to the back surface of the edge portions 2a and 2a of the floor coverings 2 and 2 through 8, and therefore, on the surface of the strip 7, each ridge of the ridge group 30 a is provided. Corresponding to 3a, a linear sticking area of the sticking agent 8 having high sticking strength and adhesion is formed, and excellent water resistance (water stoppage) is provided by each linear part of the linear sticking area. Sex comes to be demonstrated.

  When pressed by the rolling roller 11 or the like as described above, wrinkles are generated at the edge 7a of the belt 7 or the floor covering material, and the rainwater permeation path is formed between the belt 7 and the edge 2a, 2a of the floor covering. Or the belt-like body 7 may be partially damaged. Also, between the belt-like body 7 and the edge portions 2a and 2a of the floor covering material due to uneven application of the adhesive 8 or the like. There may be rainwater infiltration paths. Therefore, after being pressed by the rolling roller 11 or the like, the seam liquid or dope cement used as the adhesive 8 is injected from the joint 4 between the strip 7 and the edge portions 2a and 2a of the floor covering material, It is desirable to block infiltration paths such as rainwater.

  In addition, you may make it perform the V-grooving operation | work of the said joint 4 after said contact | attachment (sticking) attachment process is complete | finished.

  Then, in the last step, as shown in FIG. 6 (f), the joint 4 of both floor covering materials 2 and 2 is closed with the seam treatment material 5 to complete the seam construction of the floor covering material. As described above, the sealing treatment of the seam 4 with the seam treatment material 5 uses a sealing material, a welding resin rod or a seam liquid as the seam treatment material 5, and fills the seam 4 with a sealing material or welds the seam 4. What is necessary is just to carry out resin welding with a resin rod, or to weld the joint 4 with a seam solution or dope cement.
