Description

  The present invention relates to a construction method for laying a large ceramic plate on a floor surface, and particularly relates to a method that makes it difficult to cause a step at a joint portion of the large ceramic plate and allows easy construction.

  For example, conventionally, a mortar is spread on a building floor (a basic surface such as a “floor slab”), and a flat surface is formed, and then a tile is pasted to form a floor surface. When using a large ceramic plate, unless the mortar surface is made more accurate than in the case of mosaic tiles, the height of the end portions is not uniform, and a large step is likely to occur at the joint. The level difference in the joint is a problem from the viewpoint of appearance and safety. Further, if a space is generated between the back surface of the ceramic plate and the mortar surface due to unevenness, the adhesive force is reduced.

In order to finish the floor to a flat surface, a method of obtaining a flat surface using “mortar dumpling” is disclosed. (See Patent Document 1 FIG. 1)
A mortar dumpling 30 is disposed on the surface of the floor slab 10, and before the mortar is cured, a floor base material 40 is installed to form a flat floor base. Then, it is described that the floor finishing material 50 is laid thereon.

  However, according to the method described in Patent Document 1, since the “point” is supported by the mortar dumplings and the mortar dumplings are plastically deformed, particularly when a large ceramic plate is applied, a very high skill is required to obtain the level. is necessary.

  On the other hand, a plurality of guide rails 1 serving as guides for high-precision flat surface finishing of floors are installed on a normal building floor (foundation surface) 4, and fillers 2 and 3 are filled between the guide rails, along the guide rails. It is described that a highly accurate floor surface is obtained by cutting the filler. The rail is installed while being adjusted by the shim 5 or the like so that the upper surface of the guide rail is in contact with the reference plane CC. (See Patent Document 2 and FIG. 2)

  In addition, when repairing the floor surface of a toilet or the like, a recess is formed in the floor surface so that even a non-expert can repair it, and a construction jig having a height adjustment portion and a mortar leveling guide is formed in the recess. It is described that the surface is applied smoothly by installing, pouring mortar and sliding a ruler along a mortar leveling guide. (See Patent Document 3 and FIG. 3)

  The plane formation method using the guide rail described in Patent Documents 2 and 3 is an effective technique for eliminating the unevenness of the building floor. In particular, the method described in Patent Document 3 is said to be able to be repaired even if it does not have skilled skills in a short period of time. However, there is room for further improvement when laying a plurality of large ceramic plates. That is, the large ceramic plate has thickness variations and warpage, and there is a problem that a step is generated in the joint portion when the large ceramic plates are brought into contact with each other. In addition, since the filler such as mortar shrinks as it hardens, there is a slight difference in height between the vicinity of the guide rail and the central portion between the guide rails. This difference is not a problem when constructing mosaic tiles, but when a large ceramic plate is applied, there is a problem that unevenness can occur and cannot be ignored.

  This invention is made | formed based on recognition of this subject, and when using a large ceramic board for floor finishing, it aims at providing the construction method with which the level | step difference of the large ceramic board in a joint part does not arise easily.

  A first invention is a method of forming a floor surface using a large ceramic plate, a step of installing a plurality of guide rails on a building floor surface, a step of filling a filler between the guide rails, and a guide It is a floor surface construction method characterized by having a step of leveling the filling along the level and a step of attaching a large ceramic plate.

  According to this construction method, the occurrence of unevenness can be significantly and easily reduced by leveling using the guide rail. Therefore, a non-contact area with the base | substrate (surface formed with the filler) of a large sized ceramic board can be reduced.

  Moreover, 2nd invention is the construction method which affixes a large-sized ceramic board so that the side and a guide rail may become parallel in 1st invention.

  It is inevitable that undulation will occur along the guide rail. According to this construction method, since the ceramic plate is attached along the base obtained from the filler (any one of mortar, resin mortar, and mortar), the adhesion between the ceramic plate and the base can be enhanced. Furthermore, the work can be divided for each area divided by the guide rail, and it is not necessary to construct the entire floor at once. It is also excellent in that the degree of freedom of work is increased.

  Moreover, 3rd invention is the construction method which arrange | positions a guide rail in the 2nd invention in the center vicinity with respect to the edge | side of a large sized ceramic board.

  Large ceramic plates have minute convex warpage. On the other hand, the filling is recessed at the center between the rails due to cure shrinkage. Therefore, if the positional relationship between the guide rail and the large ceramic plate is as described above, the floating of the large ceramic plate can be minimized, so that cracking and peeling after construction can be prevented and the level difference in the joints can be reduced. Can do.

  Moreover, 4th invention is the construction method in which the space | interval of a some guide rail is equivalent to the length of the one side (preferably short side) of a large sized ceramic board in any one invention of 1st to 3rd invention. .

  According to this construction method, since the large ceramic plate always covers one guide rail, the floor can be flattened with high accuracy and the work efficiency can be increased by reducing the number of rails. Further, since the floating of the large ceramic plate can be minimized, it is possible to prevent cracking and peeling off after construction, and to further enhance the effect of reducing the level difference at the joint.

  In addition, in the fifth invention, in any one of the first to fourth inventions, the step of installing the guide rail includes setting up an anchor pin on the building floor and attaching the guide rail to the anchor pin. This is a featured construction method.

  According to this construction method, the leveling can be easily performed in spite of the simple structure of the members.

  The sixth invention is a floor obtained by the construction method described in the first to fifth inventions.

  The floor obtained by this construction method becomes a floor surface having a good construction surface in which the level difference at the joint is suppressed to a minimum and a gap on the back surface of the ceramic plate is hardly generated.

  According to the aspect of the present invention, when a large ceramic plate is used, there is provided a construction method in which a large step is unlikely to occur at the joint and the gap on the back surface of the ceramic plate can be reduced.

  In the present invention, the “large ceramic plate” has a thickness of 1 mm or more and 10 mm or less, preferably 1 mm or more and 6 mm or less, a length of one side of 400 mm or more and 3000 mm or less, and preferably a short side of 450 mm or more and 1000 mm or less. It is a ceramic plate of 450 mm or more and 2000 mm or less. The large ceramic plate includes a single ceramic plate, a composite plate including a stone material, a stone plate, an inorganic plate such as a metal plate or gypsum, a glass fiber cloth or a plywood plate, and the like.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a diagram in which a large ceramic plate is attached to a floor according to an embodiment of the present invention. Moreover, FIGS. 2-6 is a schematic diagram showing the construction method of the floor surface concerning this embodiment.
1 to 6 are schematic perspective views of the floor construction as viewed obliquely from above. FIG. 7 corresponds to a schematic cross-sectional view of FIG. 1 viewed from the front.

  The floor obtained by the floor construction method according to the present embodiment will be described with reference to FIG. A large ceramic plate 1 is attached to the building floor F via a guide rail 14 and a mortar 20. The large ceramic plate 1 has a thickness of 6 mm, a short side of 900 mm, and a depth (long side) of 1800 mm. The construction was carried out so that the height of the upper surface (finished surface) of the large ceramic plate 1 was about 60 mm from the building floor surface F (foundation surface).

The construction method which is this embodiment is demonstrated using FIGS. 2-5.
As shown in FIG. 2, in order to arrange the guide rails, the ruled lines 10 are marked on the building floor F (foundation surface) at a pitch of 900 mm according to the length of the short side of the large ceramic plate 1. At this time, the ruled line 10 is preferably marked in the long side direction near the center of the short side of the large ceramic plate. Here, “near the center” is a range of about 1/3 of the center when the short side of the ceramic plate to be laid is divided into 1/3, and even a slight deviation from the center line is allowed. The

  In accordance with the ruled line 10 of the building floor F (foundation surface), a hole 11 for driving an anchor is drilled. The hole 11 was a hole having a diameter of 18 mm and a depth of 30 mm, for example. As the position of the hole, when the length of the guide rail is set to 1800 mm in accordance with the length of the long side of the ceramic plate, the first hole 11 is opened at a position of 400 mm along the ruled line from the wall surface in the depth direction. The second hole 11 is opened at a position separated by 1000 mm. Similarly, holes 11 are made in other ruled lines. Next, a rod pile as an anchor is driven into these holes 11 with a hammer or the like. As the anchor, a rod pile having a size of 15 mm and a length of 120 mm was used. The reason for punching holes at such positions is to fix the guide rail to the building floor at a plurality of locations. In this example, a mode in which two anchors are fixed in the vicinity of both ends of the guide rail is shown. However, the present invention is not limited to this, and a hole is provided so that the vicinity of both ends of the guide rail and the vicinity of the center can be fixed with three or more anchors. It may be provided. For example, when the guide rail to be installed is 1800 mm, it is preferable to make a hole so that the guide rail can be fixed at three points: a position 50 mm from the end of the guide rail, a position 900 m, and a position 1750 mm.

  As shown in FIG. 3, a reference line 13 is drawn on a bar pile 12 of the anchor that has been driven by a laser marking device or the like. The reference line 13 (the height of the upper surface of the guide rail) drawn on the bar pile 12 is set to a height that is about 15 mm lower than the finishing height in consideration of the thickness of the large ceramic plate. Note that the height of the reference line varies depending on the thickness of the ceramic plate and the height of the finished surface. In this embodiment, the reference line 13 is drawn at a position of 45 mm in height on the bar pile 12 with a laser marking device.

  Next, as shown in FIG. 4, the guide rail 14 is fixed to the bar pile 12 using a nail or the like in accordance with the reference line 13. By doing in this way, it can prevent that the guide rail 14 moves, when mortar etc. are poured.

  In addition, after fixing the guide rail 14 to the bar pile 12, when the bar pile 12 protrudes from the upper surface of a guide rail, the part of the bar pile 12 which has come out is cut so that it may become lower than the upper surface of the guide rail 14. . In this embodiment, since the height of the bar pile 12 protruding from the building floor F (foundation surface) is 90 mm and the reference line is 45 mm, the protruding 45 mm portion is lower than the upper surface of the guide rail 14. Cut diagonally. Moreover, you may prepare the bar pile with a low height beforehand.

  Here, the guide rail 14 may be made of wood or the like, but is preferably made of resin or metal having lower water absorption. Fixing the guide rail 14 to the bar pile 12 is not limited to driving with nails but may be fixing with screws.

  After the guide rail 14 is fixed, the filler is filled. As the filler, mortar, resin mortar, bedding mortar, and cement can be used alone or in combination. An example in which resin mortar and bedding mortar are used for the filling is shown below. As shown in FIG. 5, the resin mortar 21 is applied to the building floor F (foundation surface). The thickness of the resin mortar 21 was about 5 mm on average after the construction. After application of the resin mortar 21, the mortar 22 is filled between the guide rails 14. Thereafter, the spread mortar 22 is pressed and hardened.

  Thereafter, as shown in FIG. 6, a ruler 30 is bridged to the upper end of the guide rail 14, and the ruler 30 is slid along the guide rail 14, so that the excess mortar 22 is scraped off and the surface of the laid mortar is removed. Level. After scraping off the extra mortar 22 with the ruler 30, the surface of the mortar 22 is trimmed with a wooden trowel, and the upper surface of the mortar 22 becomes a highly accurate plane. Thereafter, the mortar 22 is appropriately dried, and a base 22a to which the large ceramic plate 1 is attached is completed. In this example, the spread mortar is used, but a filler having high fluidity may be used instead of the spread mortar.

  After the mortar 22 is dried, the height of the base 22a is approximately 45 mm. The adhesive 23 is applied to the upper surface of the base 22a with a 10 mm × 10 mm comb so as to have a thickness of about 8 mm to 10 mm. Thereafter, the large ceramic plate 1 is placed on the base a. In the joint portion where the large ceramic plate 1 is attached, the height is adjusted so that no step is generated at the end of the large ceramic plate 1.

  Here, as shown in FIG. 7, when the mortar 22 is dried, the mortar between the guide rail 14 and the guide rail 14 contracts and becomes slightly concave, but the height of the guide rail 14 does not change. The height near the center of is small but small. Further, the large ceramic plate 1 coated with glaze is often slightly warped in a convex shape, and the guide rail 14 is positioned near the center of the short side of the large ceramic plate 1 so that the mortar 22 (base 22a) of the spread mortar 22 is placed. The gap between the upper surface and the back surface of the large ceramic plate 1 is reduced, and the step in the joint portion can be reduced by adjusting the pushing into the resin mortar 23.

  As mentioned above, according to this embodiment, when using a large-sized ceramic board for floor finishing, the construction method which cannot produce a big level | step difference at a joint part can be provided.
