Description

  The present invention relates to a lining material that covers an indoor floor such as a veranda, a balcony, a flat roof, and a dirt floor, an outdoor floor such as a terrace, a sidewalk such as a park, a road, and a slope.

  For example, in a veranda or a balcony, a large number of lining materials are placed on a ground surface provided with a waterproof layer, and the floor surface for walking is constructed while protecting the waterproof layer with the lining material.

  As shown in the following Patent Document 1, the above lining material is obtained by attaching a flexible sheet to the lower surface of a lining plate partitioned into small blocks by a plurality of crack-inducing joint grooves that intersect the upper and lower sides in the vertical and horizontal directions. A large number of anchors embedded in the lining plate are projected on the upper surface of the sheet, and a large number of support legs are projected on the lower surface of the flexible sheet. It has a structure in which a continuous space is defined between the flexible sheet and the ground surface.

  And, when there is unevenness in the lower ground such as a veranda or balcony, the flexible sheet is bent and supported following the small block where the crack is induced by the crack-inducing joint groove of the lining plate. Since the legs are laid in conformity with the unevenness of the ground surface, the lining material itself is installed in a substantially flat state with respect to the ground surface.

  Further, regarding the molding of the lining material, a lining plate molding die that can be opened on the upper surface is used, the joint groove forming wall is raised inward from the bottom wall of the molding die, and a molding material for the lining plate is formed. The mold is filled into the mold, the anchor is embedded in the lining plate from the open surface of the mold, and the upper surface of the flexible sheet is pressed against the lower surface of the molding material so as to adhere. A lining material having a flexible sheet and a lining plate formed and hardened on the upper surface of the flexible sheet is obtained.

Japanese Patent No. 3746051

  However, in the lining material of Patent Document 1 described above, cracks are induced at the bottom between the small blocks 3a defined by the crack-inducing joint grooves 7 in order to adapt to the unevenness of the lower ground such as a veranda or a balcony. As shown in FIG. 15, the mortar fragments 15 of the molding material remain in the cracked portion and mesh with the cracked portion and the spots, and the jointed small blocks 3a cannot return to the original flat state. As a result, the appearance of building the floor may be harmed.

  In addition, when the upper surface of the flexible sheet is brought into close contact with the lower surface of the molding material of the lining plate, an air pool is formed between the flexible sheet and the lining plate, and a strong bond between the flexible sheet and the lining plate is obtained. There was also a possibility that rainwater or the like would accumulate between the cracked part (bottom part) of the joint groove and the flexible sheet or other than the cracked part of the joint groove, causing frost damage in winter.

  The present invention was developed in order to effectively solve the problems of conventional lining materials having such crack-inducing joint grooves, and is flexibly applied to the lower surface of a lining plate partitioned by crack-inducing joint grooves. A flexible sheet along the bottom of the crack-inducing joint groove of the above-mentioned lining plate, which is a covering material to which a sheet is attached and adapts to the unevenness of the ground surface by a crack induced at the bottom of the crack-inducing joint groove A through hole is formed in a corresponding part of the above, and joint cracks generated by the above-described crack are released from the through hole.

  In addition, moisture accumulated between the cracked bottom portion of the crack-inducing joint groove and the flexible sheet is released from the through hole.

  The flexible sheet includes a plurality of support legs protruding downward, and a continuous gap is defined between the flexible sheet and the base surface via the plurality of support legs. The above joint cracks and moisture are released.

  The flexible sheet includes a large number of anchors protruding upward, the large number of anchors are embedded in the lining plate, and the flexible sheet is attached to the lining plate.

  Therefore, in the present invention, a through hole is formed in the corresponding portion of the flexible sheet along the bottom of the crack-induced joint groove, and the joint cracks generated by the crack in the joint groove are released from the through hole. For example, even if cracks are induced between the small blocks defined by the crack-inducing joint grooves, and joint cracks are generated, the joint cracks are released from the through hole, In addition, the joint cracks do not remain at the bottom of the joint groove, and as a result, the jointed small blocks can return to the original flat state.

  In addition, since water accumulated between the cracked bottom portion of the lining plate cracking joint groove and the flexible sheet can be released from the through hole, there is no fear of frost damage in winter.

The above-mentioned joint cracks and moisture and air are surely released into the gap defined between the flexible sheet and the base surface, and in particular, the joint cracks can be surely dropped downward, so that the crack part of the joint groove Will not remain.

  Since the anchor of the flexible sheet is embedded in the lining plate, the bonding between the lining plate and the flexible sheet becomes strong.

  The present invention provides a lining material that adheres to the unevenness of the ground surface by cracking induced at the bottom of the crack-inducing joint groove, by attaching a flexible sheet to the bottom surface of the lining plate partitioned by crack-inducing joint grooves at the top surface By opening a through hole in the corresponding portion of the flexible sheet along the bottom of the crack-inducing joint groove of the lining plate, and cracking the joint cracks generated by the crack from the through hole, Even when a crack is induced at the bottom of the induced joint groove, the joint cracks do not remain in the joint groove crack part, so that the jointed small blocks can be restored to their original flat state.

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

  As shown in FIG. 1, a lining material 1 according to the present embodiment is formed of a synthetic resin flexible sheet 2 having a square shape, and is molded and cured on the upper surface of the flexible sheet 2 and layered on the upper surface. It consists of a lining board 3, and a large number of sheets are laid on the lower ground (floor ground surface) such as a veranda or a balcony to construct a walking floor having a predetermined area.

  The former flexible sheet 2 is integrally formed by injection molding or vacuum molding with a thermoplastic resin such as polypropylene, and is embedded in the lining plate 3 on the upper surface thereof as shown in FIGS. A large number of anchors 4 are projected, and a large number of support legs 5 for supporting the covering material 1 itself are projected on the lower surface, and the anchors 4 are embedded in the uncovered lining plate 3. In this way, the lining plate 3 and the flexible sheet 2 can be firmly bonded to each other, and a large number of the lining materials 1 can be placed and laid through the support legs 5. A continuous drainage gap 14 is defined between the lower grounds 13 (see FIG. 9).

  As shown in FIG. 4A, the anchor 4 projecting upward opens the upper end pushed into the lining plate 3 and the lower end rising integrally from the flexible sheet 2, and the upper end opening 4a and the lower end opening 4b. The annular flange part 4c which exhibits the anchor effect on the inner peripheral surface of the upper end opening 4a is formed.

  Further, as shown in FIG. 4B, the supporting leg 5 protruding downward has an opening 5a only at the upper end portion integrally connected to the flexible sheet 2, and the lower end portion in contact with the base surface 13 as a horizontal bottom wall. It is formed into a hollow structure completely closed by 5b, and its upper end opening 5a is sealed with the above-described lining plate 3, thereby defining an air reservoir 6 inside. It has the structure arranged on the lower surface of the flexible sheet 2 corresponding to the partition inner area of the block 3a.

  In addition to this, the flexible sheet 2 is formed on a blank surface excluding the anchor 4 and the support leg 5, and correctly on corresponding portions in the vertical and horizontal directions along the bottom of the crack-inducing joint groove 7 of the lining plate 3 described later. While opening the 1st through-hole 10 which exhibits a big rectangular shape at intervals, while opening the 2nd through-hole 11 which exhibits circular shape in the cross | intersection part of this vertical and horizontal 1st through-hole 10, A third through hole 12 having a circular shape is formed so as to surround the periphery. When comparing the second through hole 11 and the third through hole 12, the second through hole 11 is slightly larger in size, but numerically, the third through hole 12 is more numerous.

  The latter lining board 3 is formed by using a cement kneaded material in which cement and various aggregates are kneaded, and as shown in FIG. A joint groove 7 is formed, a plurality of small blocks 3 a having a square shape are defined by the respective crack-inducing joint grooves 7, and the flexible sheet 2 is attached to substantially the entire lower surface of the lining plate 3.

  Next, the molding method of the lining material 1 according to the present embodiment will be described. As shown in FIG. 6, the lining plate 3 before curing (cement kneaded material before curing) is placed in the lining material molding die 8. The anchor 4 of the flexible sheet 2 is pushed into the uncovered cover plate 3 on the open surface of the mold 8 for forming the covering material (open surface corresponding to the lower surface of the cover plate 3). On the other hand, the upper surface of the flexible sheet 2 is firmly attached to the lower surface of the pre-curing lining plate 3, and consists of the flexible sheet 2 and the lining plate 3 which is molded, cured and layered on the upper surface of the flexible sheet 2. A lining material 1 is obtained. The lining material 1 is naturally dried or hot air dried before or after demolding to promote the above curing.

  As the lining material molding die 8, a concave mold (open mold) rubber mold or a synthetic resin film mold is used, and a joint groove molding wall 9 that rises inward from the bottom wall 8 a intersects vertically and horizontally. A plurality of small blocks 3 a are defined on the upper surface side of the lining plate 3 by joint groove forming walls 9 that continuously intersect in the vertical and horizontal directions.

  For each small block 3a of the lining plate 3, the support leg 5 of the flexible sheet 2 is arranged corresponding to the inner area of the section, but the upper surface of the flexible sheet 2 is not cured. In the process of closely contacting the lower surface of the lining plate 3, as shown in FIG. 7, a part 3 ′ of the uncovered lining plate 3 is placed in the upper end opening 5 a of the support leg 5 opened on the flexible sheet 2 side. Although slightly, it flows in and hardens to define an air reservoir 6 that is completely sealed inside the support leg 5.

  Further, in the process in which the anchor 4 is pushed into the uncovered lining plate 3, as shown in FIG. 8, the uncovered lining plate 3 flows from the upper end opening 4a of the anchor 4 toward the lower end opening 4b. Then, the lining plate 3 and the flexible sheet 2 are firmly bonded.

  Further, if air is trapped between the lower surface of the cover sheet 3 and the upper surface of the flexible sheet 2 in the process of closely contacting the upper surface of the flexible sheet 2 to the lower surface of the cover sheet 3 before curing, However, in this case, air is allowed to escape to the side of the gap 14 (external) described later due to the presence of each of the through holes 10, 11, and 12 provided in the flexible sheet 2. Therefore, there is no concern that the connection between the lining plate 3 and the flexible sheet 2 is deteriorated due to the generation of air pockets.

  Accordingly, as shown in FIG. 9, if a large number of the above-mentioned rectangular covering material 1 is continuously spread vertically and horizontally on a lower ground 13 such as a veranda or a balcony via a large number of support legs 5, the ground surface 13. At the same time, a walking floor having a predetermined area is constructed, and a continuous drainage gap 14 is defined between the lower surface of the flexible sheet 2 of the entire lining material 1 and the base surface 13.

  Further, when the mortar fragments 15 are generated by the crack induced at the bottom of the crack-induced joint groove 7 in order to adapt to the unevenness occurring on the ground surface 13, in the past, as shown in FIG. In addition, it is difficult for the mortar fragments 15 to mesh with the cracks and return the small blocks 3a of the lining plate 3 to a flat state. However, under the flexible sheet 2, as shown in FIG. Since the mortar fragments 15 are dropped from the first through-hole 10 having the rectangular shape toward the external space 14, the meshing between the mortar fragments 15 and the cracked portion (bottom portion) of the joint groove 7 is effectively eliminated. Thus, the small blocks 3a that have been cracked are not locked, and the small blocks 3a can be returned to their original flat state. Thereby, the lining material 1 as a whole is also in a flat state and does not impair the appearance.

  Furthermore, even if rainwater or washing water accumulates between the cracked bottom of the joint groove 7 and the flexible sheet 2, these rainwater and washing water are released from the large first through hole 10 to the outside. In addition to being able to prevent effectively, when the upper surface of the flexible sheet 2 is pressed against the lower surface of the uncovered covering plate 3 on the open surface of the covering material forming die 8 during molding, air between the two is removed. Otherwise, there is a possibility that air can be trapped between the flexible sheet 2 and the lining plate 3, but for this, in addition to the first through hole 10, the second through hole 11 and the third through hole are used. Since air does not escape from the hole 12 to the gap 14 side and an air pocket is not formed, the flexible sheet 2 can be adhered and adhered to the lower surface of the lining plate 3. In particular, since the second through-hole 11 is opened at the intersection of the first through-hole 10 along the crack-inducing joint groove 7, it can contribute to the fall of the mortar piece 15 in addition to drainage / exhaust.

  In the above embodiment, the lining plate 3 and the flexible sheet 2 are integrally molded using the lining material molding die 8, but the present invention is not limited to this. It is also possible to form the lining plate 3 and the flexible sheet 2 separately and attach the upper surface of the flexible sheet 2 to the lower surface of the lining plate 3 with an adhesive or the like.

  In the above embodiment, the support leg 5 of the flexible sheet 2 has a hollow structure in which only the upper end portion is opened 5a and the lower end portion contacting the base surface 13 is completely closed by the bottom wall 5b. As shown in FIG. 11, the support leg 5 can be a solid cylindrical shape. However, if the support leg 5 has a hollow structure as in the present embodiment, an air reservoir 6 can be defined inside the support leg 5, so that the lining board can be used when walking on the lining board 3. The walking load such as the weight of the 3 itself and the treading pressure can be efficiently dispersed by the absorption action of the air reservoir 6 to provide a sufficient buffering effect and to ensure the necessary strength of the lining material 1 itself.

  Furthermore, for example, as shown in FIG. 12, even if the flexible sheet 2 having no support leg 5 is just pasted on the lower surface of the lining plate 3, it can be placed on the base surface 13 even if it is laid. It becomes possible to release the mortar fragments 15, moisture and air into the through holes 10, 11 and 12. In this case, it is preferable that the thickness of the flexible sheet 2 is increased to increase the height of each through hole 10, 11, 12.

  Further, as shown in FIG. 13, if the bottom side of the crack-inducing joint groove 7 is formed separately in advance, in other words, the bottom side between the small blocks 3a is separated without the crack-inducing joint groove 7 interposed therebetween. If this is done, the generation of mortar fragments 15 due to cracks at the bottom is eliminated, and water and air can be drained and exhausted from these separated locations.

  In addition, said Example is the relationship which formed the crack induction joint groove | channel 7 which cross | intersects vertically and horizontally on the upper surface of the lining board 3, and the 1st through-hole 10 was also opened by making it cross | intersect according to this. However, when the crack-inducing joint grooves 7 are formed without intersecting, the first through holes 10 are opened in parallel at intervals as shown in FIG.

  The lining material according to the present invention can efficiently release moisture and air accumulated between the flexible sheet and the lining plate in addition to the joint cracks generated by the crack induced at the bottom of the crack-induced joint groove. Therefore, if this is used on the veranda or balcony of the building, it will be convenient.
