Description

  The present invention relates to a flooring adhesive structure and a method for applying a flooring, and more particularly, to a flooring adhesive structure and a method for applying a flooring which are beautiful in edge treatment of the flooring and excellent in water tightness.

  As a construction method for synthetic resin flooring, apply adhesive such as rubber-based solvent-type adhesive to the floor base, stick the flooring on it, and then apply the four edges of the flooring. A method is known in which a watertight structure is formed by sealing with a finishing agent such as a sealing agent (Patent Document 1).

  When applying a flooring material by the above method, usually, when applying the adhesive to the floor base, using a comb iron, the comb of the adhesive in which the ridges and grooves are alternately parallel After a certain open time has passed, the flooring material is stacked and pressure-bonded, and after being properly cured, the edge of the flooring material is sealed with a finishing agent. The sealing of the edge of the flooring is performed when the edge of the flooring is close to the wall surface or the adjacent flooring, and the gap between the edge of the flooring and the wall or the joint between the adjacent flooring. If there is nothing close to the edge of the flooring, apply the finishing agent from the floor base to the edge of the flooring so that the cross-section is a right triangle. Has been done.

  However, when the flooring is stuck as described above, the solvent contained in the sticking agent is volatilized, and this volatilized solvent gas is formed by the concave line of the comb of the sticking agent and the back surface of the flooring. Because it enters into the finishing agent that remains uncured fluidity that seals the four edges of the flooring through the hollow passage as bubbles, and some of the bubbles move to the surface of the finishing agent and burst. After the finish is cured, the surface of the finish becomes uneven due to the bubbles formed inside the finish, and the surface of the finish is opened by some of the ruptured bubbles. In this case, not only is the appearance unsightly, but also water tightness is hindered. In other words, water is formed by bubbles and rupture holes, and even if water enters between the back of the flooring and the floor base or does not enter directly, it can be easily made if the surface of the finish is damaged. Water will permeate into the back side of the flooring, which will adversely affect the floor.

  The above problem is not only in the case of sticking floor materials using a solvent-type adhesive that generates solvent gas, but for example, a moisture-reactive adhesive or a two-component mixed adhesive that generates a reactive gas. This also occurs when a flooring material is stuck using a reactive reactive adhesive. Further, if the floor material to be stuck is long, the concave line of the comb of the sticking agent is lengthened accordingly, and the generation amount of solvent gas and reaction gas increases, so the above problem becomes more remarkable. .

  By the way, the above-mentioned problem takes a long curing time after the flooring is pasted, for example, the curing time is about 3 to 4 times or more than the normal curing time (about 24 hours), and solvent gas or reaction gas is used. It does not occur when the edges of the flooring are sealed with a finishing agent after sufficient release. However, such a long curing time significantly reduces the construction efficiency and cannot be a realistic solution.

  The present invention has been made under the circumstances described above, and the problem to be solved is that the floor material edge sealing treatment with a finish is beautiful, and the floor material sticking structure is excellent in water tightness. And it is in providing the sticking construction method.

  In order to achieve the above object, the flooring sticking structure according to the present invention has a combing line of a sticking agent in which ridges and ridges are alternately arranged in parallel on the surface of the floor base, and the flooring is stuck thereon. A flooring adhesive structure in which the edges of the four circumferences of the flooring material are sealed with a finishing agent, and a hollow path formed by the concave ridges of the adhesive and the back surface of the flooring material The length of the hollow path is 50 mm or less even if the finishing agent that seals the four edges of the flooring is not reached or has been reached.

  In the flooring sticking structure of the present invention, it is more preferable that all the hollow paths have not reached the finishing agent that seals the four edges of the flooring. Moreover, it is preferable to provide a blocking part between the tip of the hollow path reaching the finishing agent or between the tip and a location 50 mm in front. In the present invention, “the hollow path has not reached the finishing agent” means that the end of the hollow path is blocked immediately before the finishing agent and does not reach the finishing agent. It means both when the location near the tip of the airway is blocked at a distance of several millimeters from the finish, and when the finish is not reached with a very short hollow path of about several mm reaching the finish. It is a term to do.

On the other hand, in the floor material sticking method according to the present invention, when applying the sticking agent to the floor material sticking planned surface area of the floor base to which the floor material is to be stuck, the ridges and grooves are alternately formed. Forming the parallel adhesive adhesive combs on the entire area where flooring is to be applied, attaching the flooring on it, and then sticking the edges of the four edges of the flooring with a finishing agent This is a method of wearing, and the comb of the adhesive located along the edge of the floor basement planned surface area of the floor base is placed along the edge of the floor base planing surface area of the floor base without a gap. Or formed along the edge with an interval of 50 mm or less from the edge.
In this sticking construction method, the comb of the sticking agent located along the edge of the floor basement planned surface area of the floor base is spaced from the four edges of the floor base sticking surface area of the floor base. It is more preferable to form it along the line.

  The other sticking construction method according to the present invention is such that when the sticking agent is applied to the floor material sticking planned surface area of the floor base to which the floor material is to be stuck, the convex stripes and the concave stripes are alternately parallel. A method for applying floor coverings in which the combs of the adhesive are formed over the entire area where the flooring is to be applied, and the flooring is applied on the surface, and then the edges of the four edges of the flooring are sealed with a finishing agent. The closing portion that closes the concaves of the combs of the adhesive agent reaching the edge of the floor material adhesion planned surface area of the floor base is located along the edge of the floor material adhesion planned surface area without a gap. Or along the edge with an interval of 50 mm or less from the edge, and formed with a sticking agent before flooring sticking.

  And still another sticking construction method concerning the present invention is as follows. When applying the sticking agent to the floor material sticking planned surface area of the floor base to which the flooring is to be stuck, the ridges and the concave stripes alternately. Forming the parallel adhesive adhesive combs on the entire area where flooring is to be applied, attaching the flooring on it, and then sticking the edges of the four edges of the flooring with a finishing agent It is a construction method, and a strip that closes the comb-shaped concaves of the adhesive that reaches the edge of the floor material pasting surface area of the floor base is applied to the edge of the floor material pasting surface area. It is characterized in that it is provided before the flooring is pasted without gaps or along the edge with an interval of 50 mm or less from the edge.

  In the flooring sticking structure according to the present invention, the hollow path formed by the concave grooves of the sticking agent and the back surface of the flooring reaches the finishing agent that seals the four edges of the flooring. Even if not, the length of the hollow path is 50 mm or less. Therefore, when the hollow path does not reach the finish, solvent gas or reaction gas generated from the adhesive passes through the hollow path. On the other hand, when the length of the hollow path reaches the finishing agent and is as short as 50 mm or less, the solvent gas released from the adhesive to the short hollow path does not enter the uncured finish. Since the amount of the reaction gas is small, these gases rarely enter the uncured finish through this short hollow passage, and even if they enter, they will not form bubbles in a very small amount. Therefore, the floor material sticking structure according to the present invention does not form bubbles or rupture holes in the finishing agent that seals the four edges of the floor material. In addition, since water does not enter the back surface of the flooring from the bubble rupture hole, the watertightness is excellent.

  In the flooring adhesive structure of the present invention, all the hollow passages are configured so as not to reach the finishing agent that seals the four edges of the flooring, solvent gas and reaction gas generated from the adhesive Is very preferable since it can be surely prevented from entering the finish through all the hollow channels. Moreover, if a closed part is provided between the tip of the hollow path reaching the finishing agent that seals the edges of the four circumferences of the flooring or between the tip and 50 mm before, the hollow path reaches the finishing agent by the closed part. Even if it is lost or reached, the length of the hollow path is reduced to 50 mm or less, so that the floor material sticking structure of the present invention can be easily implemented.

  Next, the floor material sticking construction method according to the present invention is the edge of the floor material sticking plan area, the comb of the sticking agent located along the edge of the floor sticking plan face area of the floor base If the knots are formed along the edge of the flooring area where the flooring is to be pasted without any gaps, the gap is 50 mm or less from the edge and the edge is formed along the edge. Then, when the floor material is pasted, the hollow path formed by the concave line of the knot and the back surface of the floor material is along the edge of the floor material without any gap, thereby sealing the edge On the other hand, when the comb is formed along the edge with an interval of 50 mm or less from the edge of the area where the floor material is planned to be adhered, Since the length of the concave line of the other comb line in the opposite direction reaching the edge of the intended wearing area is shortened to 50 mm or less, the flooring is stuck and the edge is covered with a finishing agent. When stopped, is less than 50mm length flying in reaching the finish. Therefore, as described above, no bubbles or rupture holes are formed in the finishing agent that seals the edge of the flooring, so the flooring edge sealing process is beautiful and watertight. Can be constructed.

  Then, in the above-mentioned sticking construction method, the combs of the sticking agent located along the edge of the floor material sticking planned surface area of the floor base are arranged without gaps on the four edges of the floor sticking planned face area. If this is done, this comb-shaped recess will form a closed loop, and then there will be no hollow part reaching the finish when the flooring is stuck and the edges of the four circumferences are sealed with the finish. Thus, it is possible to reliably prevent the entrance of solvent gas and reaction gas into the finishing agent, and to reliably and easily construct a flooring sticking structure with a beautiful edge sealing process and excellent water tightness.

  In addition, as in the other application method of the present invention, the floor material is scheduled to be adhered to the blocking portion that closes the comb-shaped recesses of the adhesive agent reaching the edge of the floor material adhesion planned surface area of the floor foundation. If it is made to fit along the edge of the surface area without gaps, or along the edge with an interval of 50 mm or less from the edge, and formed with a sticking agent before sticking the flooring, then the flooring is pasted. And when the edge is sealed with a finishing agent, the hollow path formed does not reach the finishing agent due to the blocking part of the adhesive, or even if it reaches, the length of the hollow path is 50 mm. Since it will be shortened to the following, as above, bubbles and rupture holes are not formed in the finishing agent that seals the edge of the flooring, and the edge sealing process of the flooring is beautiful and watertight It is possible to construct a flooring sticking structure that is superior to the above.

  And, as in still another method of applying the present invention, the band material that closes the comb-shaped recesses of the adhesive reaching the edge of the floor material application planned surface area of the floor base, If it is placed along the edge of the planned surface area without gaps, or is provided along the edge with an interval of 50 mm or less from the edge before the floor material is pasted, then the floor material is pasted and the When the edge is sealed with a finishing agent, the formed hollow path is blocked with the band material and does not reach the finishing agent, or the length of the hollow path is 50 mm or less with the band material even if it is reached. As described above, bubbles and rupture holes are not formed in the finishing agent that seals the edge of the flooring, and the floor edge sealing process is beautiful and watertight. It is possible to construct a sticking structure for floor materials.

It is explanatory drawing of the comb iron used for the sticking construction method.

  1 to 4, the floor material 1 has a comb 2 formed on the surface of the floor base 1, and a floor material 3 is adhered thereon. The edges of the four circumferences are sealed with a finishing agent 4. As will be described later, when the adhesive comb is applied to the floor material sticking planned surface of the floor base 1, the adhesive comb 2 is scratched with a comb iron 5 as illustrated in FIG. This is a striped uneven pattern in which a plurality of ridges 2a and a plurality of ridges 2b of the adhesive are alternately parallel.

  As shown in FIG. 2, the sealing of the edge of the flooring 3 is performed when the edge of the flooring 3 is close to the wall surface 6 or the adjacent flooring 3. In the case where there is nothing close to the edge of the flooring 3 as shown in FIG. To the end face of the flooring 3 by applying the finishing agent 4 so that the cross section becomes a right triangle. Although not shown, in order to improve water tightness, a waterproof film such as polyurethane having a width of about 10 to 15 cm is previously provided on the surface of the floor base 1 along the edge of the flooring 3, or under the floor. A waterproof film such as polyurethane may be provided over the entire surface of the ground 1.

  In the sticking structure of this embodiment, as shown in FIGS. 1 and 4, the comb 2 of the sticking agent is formed in a square ring shape with no gap along the four edges of the flooring 3. The combs of the adhesive are also randomly formed on the inner side of the combs 2 of the adhesive formed in the above. For this reason, the hollow path 7 formed by the concave line 2b of the comb 2 formed in a square ring shape and the back surface of the flooring 3 constitutes a closed loop, and the finishing agent 4 that seals the four edges of the flooring 3 is sealed. And the hollow path formed by the random comb recesses inside the square annular comb 2 and the back surface of the flooring 3 is also blocked by the projections 2a of the square annular comb 2, It does not reach the finishing agent 4 on the four circumferences of the flooring 3.

  As described above, the adhesive structure of this embodiment is such that the hollow path 7 formed by the concave groove 2b of the adhesive comb and the back surface of the flooring 3 all seals the edges of the four circumferences of the flooring 3. Since it has not reached the finishing agent 4 to be stopped, solvent gas and reaction gas generated from the adhesive agent before the adhesive agent is completely cured passes through the hollow passage 7 and is not yet cured immediately after sealing. It does not enter the finished finish 4 and form bubbles or rupture holes. Therefore, in the sticking structure of this embodiment, the edge sealing process of the flooring 3 by the finish 4 is beautiful, and water does not enter the back surface of the flooring 3 from the bubble rupture hole. Excellent water tightness.

  As described above, such a function effect is achieved when a waterproof film such as polyurethane is provided on the surface of the floor base 1 to improve the watertightness and airtightness of the floor base 1 or when the floor base 1 is airtight. This is particularly noticeable when it is made of a material having high properties. That is, when the surface of the floor base 1 is inferior in airtightness, even if the hollow passage 7 reaches the finishing agent 4 around the four sides of the flooring 3, a part of the solvent gas and reaction gas generated from the adhesive is below the floor. Although the number of bubbles and rupture holes formed in the finishing agent 4 by diffusing from the ground 1 are not so many, if the surface of the floor base 1 is highly airtight, the solvent gas and reaction gas generated from the adhesive Almost all enter the finishing agent 4 through the hollow passage 7 and many bubbles and rupture holes are formed in the finishing agent 4. Therefore, the effect of preventing the suppression of bubbles and rupture holes when the above-mentioned sticking structure is adopted is extremely remarkable. Become.

  As the flooring 3, a long floor sheet or a tile floor sheet made of soft vinyl chloride resin or polyolefin resin and having a thickness of about 1 to 5 mm is suitable, such as a balcony of an apartment house or an open corridor. -It is preferably used when sticking to places exposed to semi-outdoor rainwater or cleaning water. Moreover, it is good to apply also to the flooring material constructed | assembled in the water circumference | surroundings and other places, such as an indoor toilet and a cooking chamber.

  The floor base 1 may be made of any material, but the floor base has a low air permeability, for example, a floor base formed with a waterproof coating such as polyurethane as described above, or a waterproof sheet such as a soft vinyl chloride resin. As described above, it is preferable to use a floor base coated with a metal base or a floor base formed of a non-breathable steel plate or the like because the effects of the adhesive structure of the present invention are remarkably exhibited. However, it goes without saying that it may be a porous base such as concrete or mortar and has a certain air permeability.

  As the sticking agent, urethane-based, epoxy-based, acrylic-based, modified silicone-based, rubber-based adhesives and pressure-sensitive adhesives that are diluted with a solvent in consideration of workability are used. A two-component mixed type or moisture-curing type adhesive or pressure-sensitive adhesive such as urethane type, modified silicone type, and epoxy type having excellent water resistance is preferably used. In addition, an adhesive called a solventless type diluted with a solvent having a high boiling point in consideration of improvement of the construction environment and volatilization of VOC is also used. Many of these adhesives generate a reactive gas, but if used in the adhesive structure of the present invention, no bubbles or rupture holes are formed in the finishing agent 4.

  As described above, the comb 2 of the adhesive is formed by scratching the adhesive with the comb iron 5 when applying the adhesive to the floor material planned surface of the floor base 1. Therefore, the width of the ridge 2a, the width of the ridge 2b, the height of the ridge 2a (depth of the ridge 2b), and the like are determined by the comb shape of the comb iron 5. A general comb iron 5 has a notch portion depth a of about 0.5 to 5 mm and a notch portion spacing b of about 0.5 to 6 mm. Since the width c of the open end of the part is about 0.5 to 5 mm, the comb 2 of the adhesive formed using this general comb iron is the ridge before the floor material 3 is adhered. The height of 2a (depth of the groove 2b) is about 0.5 to 5 mm, the width of the protrusion 2a is about 0.5 to 5 mm, the width of the groove 2b is about 0.5 to 6 mm, and flooring After sticking 3, the height of the ridge 2a (depth of the ridge 2b) decreases to about 0.1 to 3 mm. Of course, the comb 2 may be formed by discharging the adhesive from a tube or cartridge having a discharge hole at the tip.

  As the finishing agent 4 for sealing the edge of the flooring 3, a curing type such as epoxy, urethane, silicone, and modified silicone having a relatively high viscosity is used. Sealing the edges of the four circumferences of the flooring 3 as described above with these finishing agents 4 ensures water tightness and prevents the flooring 3 from rolling up, and further, bubbles and rupture holes are not generated. Since it is not formed, the finish of the edge sealing process of the flooring 3 becomes beautiful.

  The flooring sticking structure is easily constructed by the sticking construction method described below.

  First, as shown in FIG. 10 (a), when applying a sticking agent to the flooring sticking planned surface area 1a of the floor base 1 to which the flooring is to be stuck, a comb-like piece as shown in FIG. By scraping the sticking agent at 5, along the four edges of the floor material sticking scheduled surface area 1 a, the combs 2 in which the plurality of protruding strips 2 a and the plurality of concave strips 2 b of the sticking agent are alternately parallel are formed. In addition to forming a square ring without a gap, a random adhesive comb 2 is also formed on the inside. In that case, after forming the random comb 2 of the sticking agent over the entire flooring pasted area 1a, a square annular comb along the four edges of the flooring pasted area 1a. 2 may be formed, or conversely, after forming the square annular comb 2, the random comb 2 may be formed inside thereof. When the adhesive comb 2 is formed in this way, the concave 2b of the square annular comb 2 forms a closed loop, and the inner random comb 2 concave is blocked by the convex 2a of the square annular comb 2. Therefore, there are no comb-shaped ridges reaching the edges of the four circumferences of the floor material sticking scheduled surface area 1a. Since the comb 2 is formed manually using the comb iron 5, the convexity closest to the edge formed in parallel with the edge is caused by construction errors such as hand shaking during the work. The strip 2a may be formed about several mm away from the finish. This is because a random comb 2 of the adhesive agent is formed over the entire floor material pasting surface area 1a, and then a rectangular ring is formed along the four edges of the floor material pasting surface area 1a. This is likely to occur when the comb 2 is formed. However, the formation of the recent ridges 2a at a distance of several millimeters in this way is an error in construction, and there is no substantial difference from the fact that the ridges of the comb 2 do not reach the edge. It is desirable to suppress the construction error as much as possible so that there are no comb-shaped grooves reaching the edge.

  When the application of the adhesive and the formation of the combs in the floor material pasting planned surface area 1a are completed and a predetermined open time elapses, as shown in FIG. 10 (b), the floor material pasting planned surface area 1a. The flooring 3 is stacked and pressed on the surface, and is cured as it is. The curing time is not particularly limited, but is suitably about one day (24 hours). When cured in this way, the solvent-type sticking agent proceeds with curing while generating a solvent gas, and the reaction-type sticking agent that generates a reactive gas proceeds with curing while giving out the reaction gas. The flooring 3 is stuck so as not to peel off.

  When the floor material 3 is attached, the edges of the four circumferences of the floor material 3 are sealed with a finishing agent 4 as shown in FIG. The sealing of the edge of the flooring material is a finishing agent in the gap between the wall surface 6 and the edge or the joint between the adjacent flooring 3 and the edge adjacent to the wall surface 6 or the adjacent flooring 3. As shown in FIG. 3, as shown in FIG. 3, the finishing agent 4 is applied so that the cross-section becomes a right triangle from the floor base 1 to the end face of the flooring 3. Is done by doing. Thus, even if the edges of the four circumferences of the flooring 3 are sealed with the finishing agent 4, all the hollow paths 7 formed by the concave strips 2 b of the comb 2 of the adhesive and the back surface of the flooring 3 are all the finishing agent. 4, the solvent gas and reaction gas generated from the sticking agent do not enter the uncured finishing agent 4 through the hollow passage 7, and therefore no bubbles or rupture holes are formed in the finishing agent 4. Therefore, it is possible to construct a flooring sticking structure in which the edge sealing process of the flooring 3 by the finishing agent 4 is beautiful and watertight.

  1 to 4, the adhesive structure of the floor material is formed by forming the comb 2 of the adhesive into a square ring shape along the four edges of the floor material 3 without gaps, and the concave line of the comb 2. All of the hollow passages 7 formed by 2b and the back surface of the flooring 3 do not reach the finishing agent 4 that seals the edges of the four circumferences of the flooring 3 (does not communicate). Like the sticking structure of embodiment shown in 5, you may comprise so that the hollow path 7a whose length which reaches the finishing agent 4 is 50 mm or less may be formed.

  That is, the floor material sticking structure shown in FIG. 5 is such that random combs 2 are formed on the entire flooring sticking area, and the vertical combs along the left and right edges of the flooring 3 are left without any gaps. 2 and a horizontal comb line 2 is formed along the upper and lower edges with an interval of 50 mm or less from the upper and lower edges of the flooring 3, and the flooring 3 is adhered thereon, The edges of the four circumferences are sealed with the finishing agent 4. In this sticking structure, a hollow path formed by the random combs 2 and the concaves of the longitudinal combs 2 and the back surface of the flooring 3 serves as a finishing agent 4 that seals the upper and lower edges of the flooring 3. However, since the hollow path is interrupted in the middle by the protrusions 2a of the lateral comb lines 2 formed at an interval of 50 mm or less from the upper and lower edges of the flooring 3, the finishing agent 4 is reached. The length of the hollow path 7a is 50 mm or less.

As described above, even if the hollow path 7a reaches the finishing agent 4, if the length is as short as 50 mm or less, the amount of solvent gas or reaction gas released from the adhesive to the short hollow path 7a is small. For this reason, these gases hardly enter the uncured finishing agent 4 through the short hollow passage 7a, and even if they enter, the amount of gas does not become a very small amount. Accordingly, the floor material sticking structure of the embodiment shown in FIG. 5 also does not form bubbles or rupture holes in the finishing agent 4 that seals the four edges of the floor material 3, so that the floor material edge sealing is performed. The treatment is beautiful, and water does not enter the back surface of the flooring material from the bubble rupture hole, so that the watertightness is excellent.
In addition, both ends of the hollow path 7 formed by the concave strips 2b of the lateral comb 2 formed at intervals of 50 mm or less along the upper and lower edges of the flooring 3 and the back surface of the flooring 3, Since the floor material 3 is blocked by the protrusions 2 a at the side ends of the vertical comb 2 formed along the left and right edges of the floor material 3 without gaps, the solvent gas and the reaction gas pass through the hollow path 7 to the finishing agent 4. Never get in.

  The above-mentioned flooring adhesive structure is applied to the upper and lower edges of the flooring material planned area when applying the adhesive to the flooring material planned surface area of the floor base in the above-described pasting method. Construction can be easily performed by forming a horizontal comb line with a gap of 50 mm or less along and forming a vertical comb line along the left and right edges without a gap.

  The flooring sticking structure shown in FIG. 6 is obtained by providing a blocking part 8 with a sticking agent at the tip of the hollow part 7 reaching the finishing agent 4 that seals the edge of the flooring 3. The flooring sticking structure shown in FIG. 1 is provided with a closing part 8 with a sticking agent between the tip of the hollow part 7 reaching the finishing agent 4 that seals the edge of the flooring 3 and a location 50 mm in front. Is. A plurality of the blocking portions 8 may be provided.

  When the end of the hollow path 7 reaching the finishing agent 4 is closed with the closing portion 8 as in the sticking structure of FIG. 6, the hollow path 7 does not reach the finishing agent 4 as a matter of course, and the sticking of FIG. As in the structure, when the blocking portion 8 is provided between the tip of the hollow path 7 and a position 50 mm in front, the length of the hollow path 7a leading to the finishing agent 4 is reduced to 50 mm or less. As for the structure, bubbles and rupture holes thereof are not formed in the finishing agent 4 and the aesthetics and water tightness are remarkably improved.

  6 and 7, the floor material sticking structure is applied to the entire floor material sticking area when applying the sticking agent to the floor sticking face area of the floor base. After the floor material is formed and pasted on the floor material, the edges of the four floors of the floor material are sealed with a finishing agent. Place the closing part that closes the groove of the floor without any gap along the edge of the flooring area where the flooring is to be applied, or along the edge with an interval of 50 mm or less from the edge, It can be easily constructed by forming it with an adhesive before.

  The closed portion 8 is formed so as to close the concave groove of the comb reaching the edge without gaps along the edge of the floor material sticking planned surface area or at an interval of 50 mm or less from the edge. The adhesive may be formed by linearly extruding from a tube or a cartridge, or may be formed by extruding each concave line in a dot shape. The blocking part 8 of the adhesive formed by extrusion in a linear shape may be one or plural, and the blocking part formed by extruding in a dotted manner for each recess may be one point or multiple points. Good.

  When the blocking part 8 is formed with a sticking agent before sticking the flooring material as in the above-mentioned sticking construction method, it is formed when the flooring material is stuck and then the edge is sealed with a finishing agent. Since the hollow path to be formed does not reach the finishing agent by the blocking portion 8 of the adhesive or the length of the hollow path is shortened to 50 mm or less even if the hollow path is reached, the edge sealing of the flooring is performed. It is possible to construct a flooring sticking structure that has a beautiful stopping treatment and excellent water tightness.

  The floor material sticking structure shown in FIG. 8 has a strip 9 along the edge of the floor material 3 at the front end of the hollow portion 7 reaching the finishing agent 4 that seals the edge of the floor material 3. The floor material sticking structure shown in FIG. 9 is blocked between the tip of the hollow portion 7 reaching the finishing agent 4 that seals the edge of the floor material 3 and a location 50 mm in front. A strip 9 is provided along the edge of the flooring 3. It is preferable to use the strip 9 having a height equivalent to the height of the ridges of the combs after the floor material 3 is adhered, so that the surface of the floor material 3 is not uneven. I can finish it neatly.

  If the tip of the hollow path 7 reaching the finishing agent 4 is closed with the band material 9 as in the sticking structure of FIG. 8, the hollow path 7 does not reach the finishing agent 4 as a matter of course, and the sticking of FIG. As in the structure, when the space between the tip of the hollow path 7 and the point 50 mm in front is blocked with the strip 9, the length of the hollow path 7a leading to the finishing agent 4 is shortened to 50 mm or less. As for the structure, bubbles and rupture holes thereof are not formed in the finishing agent 4 and the aesthetics and water tightness are remarkably improved.

  The floor material sticking structure shown in FIG. 8 and FIG. 9 is applied to the entire floor material sticking plan area when applying the sticking agent to the floor sticking plan surface area of the floor base. After the floor material is formed and pasted on the floor material, the edges of the four floors of the floor material are sealed with a finishing agent. Adhering the strip material that closes the concave stripes to the edge of the floor material attachment planned surface area without gaps, or along the edge with an interval of 50 mm or less from the edge, By providing it in front, it can be easily constructed.

  When the band material 9 that becomes the blocking portion is provided before the floor material is adhered as in the above-described adhesion method, it is formed when the floor material is adhered and its edge is sealed with a finishing agent. Since the hollow path is blocked by the band material 9 and does not reach the finishing agent, or even if it reaches, the length of the hollow path is reduced to 50 mm or less. It is possible to construct a flooring sticking structure that has a beautiful treatment and excellent water tightness.

  Next, more specific examples and comparative examples of the present invention will be described.

[Examples 1-7]
Apply the adhesive to the surface of the base material using the following base material, flooring material, adhesive, finish and the comb iron shown in FIG. 11 (a: 2 mm, b: 3 mm, c: 2 mm). In addition, by scratching the sticking agent with a comb-like iron, convex stripes (width 2 mm, height 2 mm, height 0.5 mm after pasting flooring) and concave stripes (width 3 mm, depth 2 mm, but The combs are alternately formed on the surface of the base material, and the floor material is pasted after the open time shown in Table 1 below, and the environment at 20 ° C. By curing for the curing time shown in Table 1 below, by applying the finishing agent to the edges of the four rounds of the flooring so that the cross section becomes a right triangle and sealing the edges of the four rounds of the flooring, 7 types of floor material pasting structures in which the lengths of the hollow passages reaching the finishing agent for sealing one end edge of the floor material are the lengths shown in Table 1 below. The samples were prepared. However, in Table 1 below, a sample in which the length of the hollow path reaching the finishing agent is indicated as 0 mm means that there is no hollow path reaching the finishing agent.
For each of the prepared samples, when 24 hours passed, the following evaluation methods were used to evaluate the presence or absence of swelling of the flooring material, the presence or absence of bubbles in the finishing agent, and the presence or absence of bubble rupture holes in the finishing agent. It showed in Table 1.

[Comparative Examples 1 to 10]
10 types of comparative flooring adhesive structures by changing the sample preparation conditions slightly and changing the length of the hollow path reaching the finishing agent that seals one edge of the flooring to 60 mm and 100 mm As in Example 1, the presence or absence of swelling of the flooring, the presence or absence of bubbles in the finishing agent, and the presence or absence of occurrence of bubble rupture holes in the finishing agent were evaluated. The results are shown in Table 1 below. It was written together.

  From Table 1, the samples of Examples 1, 5, and 7 in which there is no hollow path reaching the finishing agent, and Examples 2 and 3 in which the length is 50 mm or less even if the hollow path reaching the finishing agent is formed. , 4 and 6 samples do not swell, and no foam bubbles or rupture holes are generated in the finishing agent, or only a small amount is generated. It has excellent water tightness, and the workability is good within 25 hours. The overall judgment is preferably acceptable or acceptable.

  On the other hand, in the samples of Comparative Examples 1, 2, 4, 9, and 10 having a hollow path length of 100 mm reaching the finishing agent, the flooring material does not swell, but the finishing agent bubbles and rupture holes are small or large. Therefore, although the appearance of the edge sealing treatment of the flooring by the finishing agent is poor, the water tightness is inferior, and the workability is good, the comprehensive judgment is rejected or rejected at all. Further, in the sample of Comparative Example 8, although the length of the hollow path reaching the finishing agent is relatively short as 60 mm, a large amount of bubbles of the finishing agent are generated and a small amount of rupture holes are generated. In order to obtain a beautiful and highly water-tight adhesive structure of the edge sealing treatment of the present invention by preventing the generation of bubbles and rupture holes in the finish from the comparison between this and Example 4 It can be seen that the length of the hollow path reaching the finishing agent needs to be 50 mm or less.

  In addition, the sample of Comparative Example 7 that does not take the open time is finished with the solvent gas and the like passing through the hollow path because the convex line of the comb of the adhesive agent is crushed when the flooring is pasted and the hollow path is not formed. Although it does not enter the agent and bubbles or rupture holes are generated, there is no escape space for solvent gas, etc., and solvent gas accumulates on the back side of the flooring, causing the flooring to swell. Pass.

  In addition, the samples of Comparative Examples 5 and 6 in which the curing time is longer than 4 times the normal curing time (24 hours), almost all of the solvent gas and the like before the edge of the flooring is sealed with a finishing agent. Is released and diffused, but there is no swelling of the flooring, no bubbles or rupture holes in the finish, but the construction time is extremely long, so the workability is extremely poor, and the comprehensive judgment is completely rejected.

  Furthermore, the sample of Comparative Example 3 in which the standing time after mixing the two liquids of Finishing Agent A was preliminarily reacted and the sample of Comparative Example 4 in which the finishing agent was thickened were the bubble rupture holes of the finishing agent. The formation of bubbles can be suppressed somewhat, but the generation of bubbles cannot be suppressed, and the overall judgment is still unacceptable. Therefore, pre-reacting and thickening the finishing agent is an effective means. I understand that there is no.

  As can be understood from the above description, whether the hollow path formed by the concave grooves of the sticking agent and the back surface of the flooring material has not reached the finishing agent that seals the four edges of the flooring material, Even if it has reached, the floor material sticking structure of the present invention having the length of the hollow path of 50 mm or less suppresses the formation of bubbles and rupture holes in the finishing agent, and seals the edges of the flooring material with the finishing agent. Since the aesthetics and water tightness of the treatment can be remarkably improved, it is extremely useful.
