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. In the case of using a large tile, unless the mortar surface is made more accurate than in the case of a mosaic tile, 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. Furthermore, if space is generated between the tile back surface and the mortar surface due to unevenness, the adhesive strength 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 an ordinary building floor surface (foundation surface) 4, and fillers 2 and 3 are filled between the guide rails, along the guides. It is described that a highly accurate floor surface is obtained by cutting an important object. 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)

JP 2001-323590 A JP 63-47461 A JP2013-155531A

  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 tiles. That is, the large tile has thickness variations and warpage, and there is a problem that when the large ceramic plates are brought into contact with each other, a step is generated in the joint portion. 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. Furthermore, the shim is used to align the upper surface of the guide rail as in the prior art document 2 because the rail is displaced during adjustment, it takes time for leveling, and the guide rail is used when filling with mortar. There are issues such as movement.

  The present invention has been made on the basis of recognition of such problems. When a large ceramic plate is used for floor finishing, an anchor used for forming a base when performing a construction in which a step of the large ceramic plate is unlikely to occur in a joint portion. It aims at providing the construction method which constructs the floor surface of a large-sized ceramic board using the kit by the pin and the guide rail which is fixed to this anchor pin, and can make a foundation | substrate into a plane, and these members.

  A first invention is an anchor pin comprising an anchor portion embedded in a floor surface and a rod-shaped portion extending from the anchor portion in a direction away from the floor surface, wherein the rod-shaped portion can be bent by a ball joint. It is an anchor pin characterized by being connected with a part.

When a hole is made in a building floor (floor slab) and an anchor is inserted and fixed, it is difficult to make a hole vertically with a drill. If the hole is tilted, the leveling may not be performed with high accuracy.
According to this anchor pin, since the rod-shaped part is connected to the anchor part so as to be bent by a ball joint, even if the hole drilled in the building floor (floor slab) is inclined, The part can be bent and corrected perpendicularly to the building floor (floor slab) or the like.

  In a second aspect based on the first aspect, the ball joint includes a ball portion and a housing that covers the ball portion, and the housing has a notch or a hole so that the ball portion is partially exposed. It is characterized by being formed.

  It is preferable to fix the rod-like portion so as not to tilt again after the rod-like portion is made vertical. Since the notch or hole is formed in the housing so that the ball portion is partially exposed, a liquid quick-drying (instant) adhesive can be suspended and fixed in the notch or hole.

  According to a third aspect of the present invention, there is provided the anchor pin according to the first or second aspect, further comprising a fixing means for preventing bending by the ball joint.

  By providing the fixing means for preventing the bending, the rod-shaped portion can be fixed so as not to be inclined again after being made vertical.

  According to a fourth aspect of the present invention, there is provided the anchor pin according to the third aspect, wherein the fixing means is a screw.

  By using the fixing means as a screw, the rod-shaped portion can be fixed so that the rod-shaped portion does not tilt again by screw tightening after the rod-shaped portion is made vertical.

  The fifth invention is characterized in that, in any one of the first to fourth inventions, the center line in the longitudinal direction of the anchor portion and the center line in the longitudinal direction of the rod-like portion are eccentric. It is an anchor pin.

  Since the center line in the longitudinal direction of the anchor portion and the center line in the longitudinal direction of the rod-shaped portion are eccentric, the degree of freedom of the rod-shaped portion can be further increased.

  A sixth invention is an anchor pin according to any one of the first to fifth inventions, wherein the rod-like part is provided with a support part for supporting another member.

  By providing the support portion on the rod-like member, other members can be supported stably.

  According to a seventh aspect of the present invention, there is provided the anchor pin according to the sixth aspect, wherein the height of the support portion can be adjusted.

  If the height of the support portion can be adjusted, it is preferable because the height of a member attached to the support portion can be easily adjusted.

  An eighth invention is an anchor pin according to the seventh invention, wherein the support portion is a nut and is screwed with a rod-like portion.

  Most preferably, the support portion is formed by cutting the rod-like portion and attaching a nut.

  The ninth invention is a kit for forming a base for constructing a flat floor, and is fixed to the anchor pin according to any one of the first to eighth inventions and the rod-like portion of the anchor pin. A kit for forming a base of a flat floor characterized by comprising a guide rail.

  As a result, if a plurality of members of the present invention are installed on the building floor and the guide rails are horizontally mounted between the members, the flooring is fixed to the guide rails, or cement or mortar is filled between the guide rails to increase the height. By leveling, a flat floor can be easily formed. On a flat floor formed of cement or mortar, floor materials such as tiles may be laid by a conventional method, or a film may be formed with a paint or a coating material. By making the member into a kit, the installer can easily obtain the construction material.

  According to a tenth aspect of the invention, in the ninth aspect of the invention, the guide rail is provided with a hole or a groove through which the rod-like portion can be inserted or penetrated. .

  If the hole or groove is provided in the guide rail so that the rod-like portion can be inserted or penetrated, the guide rail is reliably supported, so that the positional deviation hardly occurs at the time of construction, and the construction becomes easy.

  The eleventh 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, and a step of filling a filler between the guide rails. A step of leveling the filling along the guide and leveling and a step of attaching a large ceramic plate, and a step of installing the guide rail on the building floor, wherein the guide rail is the building floor The anchor pin is fixed to an anchor pin standing on the surface, and the anchor pin has an anchor portion and a rod-like portion, and the rod-like portion is connected to the anchor portion so as to be bent by a ball joint. This is a method for constructing a floor surface of a large ceramic plate.

  By installing multiple guide rails on the building floor and horizontally installing guide rails between members, the floor material can be fixed to the guide rails, or cement or mortar can be filled between the guide rails to level the height. A flat floor can be easily formed, and a floor surface of a large ceramic plate that is unlikely to cause a step can be obtained.

FIG. 10 is a schematic diagram showing an example of fixing the anchor pin and the guide rail.

  An anchor pin 100 according to the present embodiment will be described with reference to FIG. The anchor pin 100 includes an anchor portion 110 that is driven into a hole formed in the building floor F and a rod-shaped portion 120 having a predetermined length, and the anchor portion 110 and the rod-shaped portion 120 are connected by a ball joint 130. FIG. 1A shows the anchor pin 100 in a straight state, and FIG. 1B shows a view in which the rod-shaped portion 120 is bent and inclined with respect to the anchor portion 110. FIG.1 (c) is a figure which shows the cross section of Fig.1 (a). As shown in FIG. 1B, the rod-shaped portion 120 can be inclined with respect to the anchor portion 110 by, for example, a maximum angle K of 15 °. By doing so, the rod-shaped portion can be kept perpendicular to the building floor surface F even if the holes formed in the building floor surface F are formed obliquely.

  Each part will be described in more detail. As shown in FIG. 1 (c), the anchor part 110 includes an anchor inner 111 and an anchor holder 112. The anchor holder 112 is inserted into a hole formed in the building floor F, and a slit 112a is formed at the tip, which has elasticity. The anchor inner 111 is driven into the anchor holder and spreads the anchor holder 112, and the outer periphery of the anchor holder 112 presses the inner peripheral surface of the hole of the building floor surface F so that it does not come out. The anchor inner 111 may be formed with a screw on the outer periphery.

  The ball joint 130 includes a ball stud 131 and a housing 132 (ball receiving portion). In the present invention, the ball stud 131 is integrated with the anchor portion 110 and the housing 132 is integrated with the rod-shaped portion 120. However, the ball stud is integrated with the rod-shaped portion 120 and the housing is It may be connected integrally with the anchor part 110. In the latter case, when the rod-shaped portion is fixed by adjusting the angle of the rod-shaped portion, an adhesive can be poured into the sliding portion of the housing 132 with the ball stud 131.

  The housing 132 is formed with a hole 133 or a notch (not shown). After the anchor portion 110 is driven and the rod-shaped portion 120 is made vertical, an adhesive can be poured into the hole 133 or notch so that the rod-shaped portion 120 does not move. By doing so, as will be described later, when the guide rail is attached and mortar is filled, the guide rail does not move. As a fixing means, in addition to the above-mentioned adhesive, a screw (not shown) can be screwed into the hole 133 and fixed by pressing pressure.

  In the present invention, the rod-shaped portion has a predetermined length. After fixing multiple anchor pins on the building floor (floor slab) at predetermined intervals, level out and mark the horizontal plane height or cut the rod-shaped part to align the height, to the predetermined height A horizontal plane can be formed by filling mortar or the like. As a preferred embodiment of the present invention, a male screw 121 is formed on the outer periphery of the rod-shaped portion 120. A nut 122 is screwed onto the male screw 121, and the nut 122 is moved up and down so that the height can be adjusted. By doing so, the heights can be more easily aligned. Furthermore, according to this aspect, the guide rail can be supported by the nut. By aligning the height of the nut from the building floor F, the height of the upper surface of the guide rail can be maintained with high accuracy.

  FIG. 8 shows a modification of the anchor pin of the present invention. In this embodiment, an example in which the center line in the longitudinal direction of the anchor portion 110 of the anchor pin 100 and the center line in the longitudinal direction of the rod-shaped portion 120 are eccentric is shown. In this embodiment, the eccentricity is 2.5 mm in the radial direction. It can cope with a deviation of 5 mm in diameter. As a result, even if the hole drilled in the building floor F is opened obliquely and the position is shifted, the anchor portion 110 is driven into the hole and fixed, and then the rod-shaped portion 120 is bent and rotated within the range of eccentricity. It can be accurately positioned with respect to the horizontal position of the

  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 short side of the large ceramic plate 1 is a tile having, for example, 900 mm and a depth of 1800 mm. The guide rail 14 is located in the longitudinal direction of the large tile 1 near the center of the short side of the large ceramic plate 1.

The construction procedure according to this embodiment will be described with reference to FIGS.
As shown in FIG. 3, 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 in accordance with the length of the short side of the large ceramic plate 1. At this time, the ruled line 10 is preferably located 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 the guide rail is slightly shifted from the center line. Is also acceptable.

  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 1800 mm according to 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 1000 mm away from the center. Similarly, holes 11 are made in other ruled lines. 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.

  FIG. 4 shows an example in which the anchor pin 100 is driven into the hole 11 of the building floor F (foundation surface). The hole 11 in the building floor surface F (foundation surface) may be inclined, and in this case, the rod-shaped portion 120 is made vertical. After the rod-shaped portion 120 is made vertical, an adhesive is poured into the hole 133 of the housing 132 and fixed so that the ball joint does not move. Next, the nut 122 of the rod-shaped portion 120 of the anchor pin is rotated by a laser marking device or the like and moved vertically to match the height of the reference line. Here, when the height of the nut 122 is determined, it is preferable to pour an adhesive so that the nut 122 does not move. The height of the reference line (the height of the lower surface of the guide rail or the height of the upper surface of the nut 122) is set in consideration of the thickness of the large tile, the thickness of the guide rail, and the like. For example, when the thickness of the tile is 6 mm and the thickness of the guide rail is 30 mm, when the finished surface of the tile is 60 mm from the building floor F (foundation surface), the height of the reference line may be 15 mm.

As shown in FIG. 5, the guide rail 14 is placed on the upper surface of the nut 122. The guide rail 14 is preferably fixed to the rod-shaped portion 120. In the aspect shown in FIG. 5, since the rod-shaped part 120 is inserted into the insertion hole provided in the guide rail 14, the guide rail 14 is fixed to the anchor pin. Since the anchor pin 100 is fixed to the building floor and the guide rail is fixed to the anchor pin, the guide rail 14 can be prevented from moving when mortar or the like is poured. When the guide rail 14 is placed on the nut 122, if the tip of the rod-shaped portion 120 protrudes from the upper surface of the guide rail 14, the protruding portion is cut so as to be lower than the upper surface of the guide rail 14. . As long as it comes out from the guide rail according to the height of the finished surface, it may be cut in advance, or the length of the rod-shaped part 120 may be prepared.

The material of the guide rail 14 may be wood or the like, but is preferably made of resin or metal having lower water absorption.

As shown in FIG. 10, the guide rail 14 is fixed to the rod-shaped portion 120 by providing a hole 14a in the guide rail, passing the hole 14a through the rod-shaped portion 120, and then a groove 14b provided on the upper surface of the guide rail hole 14a. Alternatively, the nut is fixed to the counterbore with another nut 123. It is not limited to a nut and may be fixed with an adhesive.

  Here, when laying a plurality of large ceramic plates with short sides of 900 mm and long sides of 1800 mm, if a plurality of construction kits including a set of 1800 mm long guide rails and two anchor pins are prepared, the base is formed. In this case, the upper surface of the base can be easily made horizontal. The length of the guide rail and the number of anchor pins are not limited to this. For example, three or four anchor pins may be used for a 1800 mm guide rail.

  As shown in FIG. 6, the filler is filled after the guide rail 14 is fixed. 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. In this example, the resin mortar 21 is applied to the building floor surface 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. 7, 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 on which the large tile 1 is pasted is completed. In this example, the spread mortar is used, but a filling material having high fluidity may be used instead of the spread mortar.

  FIG. 9 is a schematic cross-sectional view in the longitudinal direction of an example in which a plurality of tiles are constructed on the floor surface. 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 22a. 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, when the mortar 22 is dried, the space between the guide rail 14 and the guide rail 14 contracts and becomes slightly concave. However, since the height of the guide rail 14 does not change, the height near the center of the mortar is not very small. Yes, but low. Further, the large tile 1 coated with the 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 tile 1 so that the upper surface of the mortar 22 (underlay 22a) The gap between the back surfaces of the large tiles 1 can be reduced, and the step in the joint portion can be reduced by adjusting the pushing into the resin mortar.

  As described above, according to the present embodiment, when a large ceramic plate is used for floor finishing, when performing a construction in which a step of the large ceramic plate in the joint portion is unlikely to occur, the anchor pin used for forming the base and the anchor pin are fixed to the anchor pin. It is possible to provide a kit using a guide rail that can be constructed on a flat surface and a construction method for constructing a floor surface of a large ceramic plate using these members.
