  The present invention relates to a jig used when a tile is applied to a building, an outdoor floor surface, a wall surface, a ceiling, or the like, and more particularly, to a jig that can apply the surfaces of adjacent tile bodies in a flush state.

2. Description of the Related Art Conventionally, a panel surface matching jig for correcting a panel surface to a surface-matched state by arranging a plurality of panels side by side on a building frame (building frame) is known (Patent Document 1).
The surface aligning jig includes a base plate portion that extends over adjacent panels, a bolt member that is integrally provided on the base plate portion and penetrates a joint portion between the panels in the thickness direction, and is fitted to the bolt member. A contact plate inserted so as to be sandwiched between the panel wall and the substrate portion, and a nut member screwed to the bolt member are provided.

Japanese Utility Model Publication No. 6-36165

However, the surface aligning jig of Patent Document 1 described above has a handle portion on the substrate portion side, and gripping the handle portion prevents the substrate portion from being rotated as the nut member is twisted. A space for twisting the nut member and a space for gripping the handle portion are required on both the front and back sides of the panel.
This means that a space for twisting or gripping is indispensable between the housing and the panel of the building. In the surface matching jig of Patent Document 1, an adhesive (mortar) is provided between the housing and the panel. Can not meet in a stable state after filling.

In addition, after making the surfaces of adjacent panels flush with each other, it takes time and labor to attach a plurality of panels to the housing, resulting in a reduction in work efficiency.
Furthermore, since the plurality of panels arranged are not supported from when the surface matching jig of Patent Document 1 is removed to when it is attached to the housing of the building, once the panel surface is flush, There is a possibility that deformation such as warping or twisting may occur during the mounting of the.

  Therefore, the present invention enables face-to-face matching in a state in which an adhesive is filled between the frame of a building or outdoor frame, and tiles, and prevents the bottom plate from being rotated by twisting, It is another object of the present invention to suppress excessive twisting in the shaft.

  The tile construction jig 10 according to the present invention is a tile construction jig for flattening the surface of an adjacent tile body T, and the tile body T is supported on a bottom plate 11 that supports the adjacent tile body T from the back surface side. A shaft 12 projecting to the surface side of the shaft 12 is provided, and the adjacent tile body T is brought into contact with the male thread groove portion 13 of the shaft 12 from the surface side by an abutment surface 14 substantially orthogonal to the projecting direction of the shaft 12. The shaft 12 is provided with a pressing member 15, and a flat plate portion 16 formed between the male screw groove portion 13 and the bottom plate 11 is provided on the shaft 12. The flat plate portion 16 is wider than the diameter D of the male screw groove portion 13. And the 1st characteristic is that the separation part 17 which makes the said baseplate 11 and the shaft 12 separable is formed.

  A second feature of the tile construction jig 10 according to the present invention is that, in addition to the first feature, the separating portion 17 has a longitudinal direction along a radial direction L substantially orthogonal to the protruding direction of the shaft 12. It is in that it is a thin part.

  A third feature of the tile construction jig 10 according to the present invention is that, in addition to the first or second feature, a female screw hole 18 that is screwed into the male screw groove 13 of the shaft 12 to the holding member 15. And a tapered surface 19 for guiding the shaft 12 to the female screw hole 18 is formed.

Due to these features, the tile construction jig 10 according to the present invention provides the flat plate portion 16 on the side of the tile body T by providing the flat plate portion 16 on the shaft 12 protruding from the bottom plate 11 that supports the tile body T from the back surface side. Even if the presser member 15 brought into contact with the end surface and screwed into the male thread groove 13 of the shaft 12 is twisted, the bottom plate 11 can be prevented from being rotated.
For this reason, there is no need to provide a detent such as a handle on the bottom plate 11 or a space for grasping the detent, and a state in which an adhesive, cement, mortar, or concrete is filled between the building frame and the tile T. It is also possible to meet with each other.
Furthermore, the holding member 15 is twisted by making the flat plate portion 16 wider than the diameter D of the male screw groove portion 13 (that is, making the plate width W of the flat plate portion 16 larger than the diameter D of the male screw groove portion 13). It is possible to receive the rotational moment generated at the time of dispersion with a flat plate portion 16 wider than the male screw groove portion 13 over a wider range from the rotation center.
At the same time, since the rotation moment can be dispersed, the rotation moment per unit volume becomes smaller. Therefore, the separation portion is provided in the flat plate portion 16 which is wider than the case where the separation portion 17 is provided in the narrow male screw groove portion 13. In the case where 17 is provided, excessive separation due to twisting of the pressing member 15 can be suppressed.

In addition, by making the separation portion 17 a thin portion, the separation portion 17 can be provided only by partially changing the plate thickness A of the flat plate portion 16. In addition, since there is no change in the plate width in the thin wall portion (separating portion 17), even if the separating portion 17 is provided, the holding member 15 is dispersed over a wide range from the rotation center without any trouble. It is possible to receive a rotational moment generated when twisting.
At the same time, by forming the thin portion (separating portion 17) long along the radial direction L of the shaft 12, the bottom plate 11 can swing with respect to the shaft 12 along the thin portion. Even if there is a difference in the thicknesses t and t ′ of the adjacent tile bodies T, the bottom plate 11 swings according to the difference and can be supported on the adjacent tile bodies T from the back side.

  Then, by forming the tapered surface 19 that guides the shaft 12 to the female screw hole 18 of the presser member 15, the positions of the female screw hole 18 and the male screw groove 13 are bothered when the presser member 15 is screwed. Since it is not necessary, the surface matching can be simplified and the work efficiency can be improved.

  In the tile construction method according to the present invention, the adjacent tile body T is supported by the bottom plate 11 from the back surface side, and the pressing member 15 is provided in the male screw groove portion 13 of the shaft 12 protruding from the bottom plate 11 to the front surface side of the tile body T. The surface of the adjacent tile body T is flattened by screwing and pressing the adjacent tile body T from the surface side by the contact surface 14 that is substantially orthogonal to the protruding direction of the shaft 12 in the pressing member 15. The separation of the bottom plate 11 and the shaft 12 is performed between the male screw groove 13 and the bottom plate 11 by a separation portion 17 formed in a flat plate portion 16 wider than the diameter D of the male screw groove 13. Features.

  The second feature of the tile construction method according to the present invention is that, in addition to the first feature, the adjacent tile body T is supported by the bottom plate 11 from below, and the shaft 12 is supported from the bottom plate 11 to the tile body T. And the adjacent tile body T is pressed from above by the contact surface 14 of the pressing member 15.

With these features, the tile construction method according to the present invention supports the adjacent tile body T with the bottom plate 11 from the back surface side and presses it with the pressing member 15 from the front surface side, thereby allowing the surface of the adjacent tile body T to be touched. After flattening, the bottom plate 11 and the shaft 12 are separated by the separation portion 17 formed in the flat plate portion 16 having a plate width W larger than the diameter D of the male screw groove portion 13 to twist the holding member 15. Even if the flat plate portion 16 is brought into contact with the side end surface of the tile body T, it is possible to prevent the bottom plate 11 from being rotated, and there is a space for holding the rotation stopper such as a handle or the like. It becomes unnecessary, and it becomes possible to perform surface matching in a state where cement, adhesive, mortar, or concrete is filled between the building frame and the tile body T.
Since this surface-matched state can be dried and attached to the housing, there is no risk of extra warping or twisting, and after drying, the separating portion 17 only needs to separate the shaft 12 from the bottom plate 11. Also, work efficiency can be improved.
In addition to this, by making the flat plate portion 16 wider than the male screw groove portion 13, the rotational moment generated when the holding member 15 is twisted can be distributed and received over a wide range. Even if the separation part 17 is provided, the twisting of the presser member 15 is prevented from being excessively twisted off.

  When the tile body T is constructed on the floor surface by supporting the adjacent tile body T with the bottom plate 11 from below and pressing it with the contact surface 14 of the pressing member 15 from above, the building frame and tile The cement or adhesive filled between the bodies T does not flow, and the tile body T can be attached to the cabinet while maintaining a more even state, improving the finish and speeding up the work. Connected.

  Prevents the bottom plate from being turned around due to torsion of the presser member and excessive twisting, and improves the working efficiency by matching the surface of the building with the adhesive filled between the building frame and the tile body. It is possible to achieve both.

(A) is a perspective view which shows the tile construction jig which concerns on 1st Embodiment of this invention, (b) is a sectional side view which shows the usage condition of a tile construction jig. It is a perspective view which shows the tile construction jig which concerns on 2nd Embodiment of this invention. It is a perspective view which shows the pressing member of the tile construction jig which concerns on 3rd Embodiment of this invention.

In order to achieve the above-described object, a tile construction jig 10 according to the present invention will be described with reference to FIGS.
FIG. 1 shows a tile construction jig 10 according to the first embodiment of the present invention. The tile construction jig 10 includes a substantially disc-shaped bottom plate 11 that supports an adjacent tile body T from the back surface side. And a pressing member 15 for pressing the adjacent tile body T from the surface side.
The tile construction jig 10 is made of polycarbonate (PC), polyamide (PA), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), polypropylene (PP), polyacetal (POM), acrylonitrile. -It is comprised with thermoplastic resins, such as plastics, such as a butadiene styrene (ABS).

The bottom plate 11 includes a shaft 12 protruding upward from the upper surface thereof, a flat plate portion 16 provided on the proximal end side of the shaft 12, and a male screw groove portion 13 provided on the distal end side of the flat plate portion 16. Yes.
The male screw groove portion 13 has a substantially cylindrical shape, and a male screw groove is formed on the peripheral surface thereof.
Further, the flat plate portion 16 is configured to be wider than the diameter D of the male screw groove portion 13, that is, to have a plate width W of the flat plate portion 16 larger than the diameter D of the male screw groove portion 13. A thin portion 17 (separation portion) is formed.

Thus, by providing the separation portion 17 as a thin portion, the separation portion 17 that can separate the bottom plate 11 and the shaft 12 of the thermoplastic resin is provided only by partially changing the plate thickness A of the flat plate portion 16. I can do it. In addition, since there is no change in the plate width in the thin wall portion (separating portion 17), even if the separating portion 17 is provided, the holding member 15 is dispersed over a wide range from the rotation center without any trouble. It becomes possible to receive a rotational moment generated when twisting.
Further, the thin portion 17 has a longitudinal direction along a radial direction L substantially orthogonal to the protruding direction of the shaft 12, and the bottom plate 11 can swing with respect to the shaft 12 along the thin portion 17. It has become.
This is because even if there is a difference in the thicknesses t and t ′ of the adjacent tile bodies T, the bottom plate 11 swings according to the difference, and both of the adjacent tile bodies T can be supported from the back side.

As the separating portion 17, in addition to the thin-walled portion, a notch cut in the radial direction L of the shaft 12, or a line formed along the radial direction L of the shaft 12 and penetrates the flat plate portion 16 in the thickness A direction. A plurality of holes may be used.
In addition, the cross-sectional area (the cross-sectional area along the radial direction L of the shaft 12) in the separation part 17 such as the thin-walled part described above is smaller than the cross-sectional area of the part other than the separation part 17 (non-separation part 20). It is preferable that the length of the separation portion 17 in the radial direction L of the shaft 12 is substantially the same as the plate width W of the flat plate portion 16.
Since the upper end surface 16a of the flat plate portion 16 is substantially at the same height as the lower end of the male screw groove portion 13, when the presser member 15 is screwed to the lower end of the male screw groove portion 13, the presser member 15 It is the contact surface which contacts.

The holding member 15 closes the upper opening of the circular cylindrical body 31 with a circular upper plate 32, and an upper column body 33 erected from the center of the upper plate 32 on the upper surface of the upper plate 32, It has a pair of grip plates 34a and 34b which are erected from the diameter passing through the center of the plate 32 with the upper column body 33 interposed therebetween.
The upper opening of the cylindrical body 31 may be closed by the upper plate 32 as described above, but a part of the upper opening may be closed.
Further, the diameters of the cylindrical body 31 and the upper plate 32 (that is, the diameter 15D of the pressing member 15) are formed larger than the diameter 11D of the disk-shaped bottom plate 11, and the surface side (upward) with respect to the tile body T. The range that can be pressed from the back side may be wider than the range that is supported from the back side (downward). Conversely, the range that can be pressed from the front side may be narrower or substantially equal to the range that is supported from the back side.

The lower end edge surface of the cylindrical body 31 forms a contact surface 14 that is substantially orthogonal to the protruding direction of the shaft 12 and presses the adjacent tile body T from above. By pressing from above, the surfaces of adjacent tile bodies T are flattened (in a flush state).
Further, in this way, the contact surface 14 is not the entire lower surface of the presser member 15 but an annular lower end edge surface, so that the presser member 15 is twisted and finally the tile body T is tightened. The contact portion with the surface of the body T is reduced, the frictional force excessive for twisting the pressing member 15 is reduced, and the range that can be pressed by the pressing member 15 is expanded as much as possible.
In addition, the tile body T in the present invention may have any surface such as hard, semi-hard, and soft.

A female screw hole 18 that is screwed into the male screw groove 13 of the shaft 12 is formed along the axial direction of the upper column 33 from the center of the lower surface of the upper plate 32.
Further, the female screw hole portion 18 penetrates to the upper surface of the upper column 33, and even if the axial length 13J of the male screw groove portion 13 is longer than the axial length 18J of the female screw hole portion 18, a flat plate Screwing is possible until the upper end surface 16a of the portion 16 contacts the lower surface of the upper plate 32.
Accordingly, if the axial length 13J of the male thread groove 13 is set to be long, it can be constructed even when the thick tile body T is mated, and the male tile groove T can be constructed even when the thin tile body T is constructed. Since the surplus portion of the screw groove portion 13 comes out from above the female screw hole portion 18, the pressing member 15 can be twisted to perform surface matching, and the tile construction jig 10 of the present invention has a tile body T having various thicknesses. It becomes possible to cope with.
Such surface alignment is performed by gripping and twisting the pair of gripping plates 34a and 34b in the pressing member 15.

Next, a usage mode of the tile construction jig 10 according to the first embodiment of the present invention, that is, a tile construction method, first, a case where a tile body T is constructed on a floor of a building will be described (see FIG. 1B). .
First, cement S (adhesive) or the like is applied onto the floor frame K of the building, and the bottom plate 11 of the tile construction jig 10 of the present invention is placed on the coated cement S or the like so that the shaft 12 protrudes upward. Place.
Two tile bodies T are placed on the bottom plate 11 and the cement S in a state where the space between the shafts 12 protruding upward is narrowed.
The female screw hole portion 18 of the pressing member 15 is screwed into the male screw groove portion 13 of the shaft 12 protruding from between the adjacent tile bodies T placed thereon, and the holding plates 34a and 34b are held and twisted.
As described above, even if the holding member 15 is twisted, the flat plate portion 16 is brought into contact with the side end surface of the tile body T, so that the bottom plate 11 can be prevented from being rotated and the handle or the like can be rotated. Stops and a space for holding the detents are not required, and surface matching can be performed in a state where cement S or the like is filled between the building frame K and the tile body T.
At this time, the adjacent tile bodies T are preferably arranged so that the gap (distance) between them is substantially the same as the diameter D of the male screw groove 13.

Further, a rotational moment is generated by twisting the presser member 15, and this rotational moment can be distributed and received over a wide range by the flat plate portion 16 wider than the male screw groove portion 13. Even if the separation part 17 is provided, the twisting of the presser member 15 is prevented from being excessively twisted off.
As described above, as the presser member 15 is twisted while suppressing twisting, the adjacent tile bodies T can swing from the back surface side so that the front surface side is flush with the contact surface 14. Supported by the bottom plate 11, each moves up and down according to the thicknesses t and t ′ of the tile bodies T.
Due to this vertical movement, the tile bodies T can be aligned with each other, and the cement S or the like is present between the tile bodies T and the housing K. Therefore, the cement S also moves until drying according to the movement of each tile body T. Fill.

Moreover, it can be dried and attached to the housing K in the state where the surfaces are aligned, and the shaft 12 can be separated from the bottom plate 11 by the separating portion 17 while the bottom plate 11 and the tile body T are stable.
The shaft 12 (and the presser member 15) is separated from the bottom plate 11 in the same manner as when the presser member 15 is twisted by holding the grip plates 34a and 34b and holding the press plate in the plate width W direction of the flat plate portion 16. This can be done by tilting the member 15 or twisting it.
On the other hand, the separated bottom plate 11 remains under the tile body T, but the joint between the tile bodies T may be filled.
In addition, after surface-matching, the shaft 12 may be first separated from the bottom plate 11 by the separation unit 17, and the cement S or the like may be dried in a state where the joints between the tile bodies T are filled.

FIG. 2 shows a tile construction jig 10 according to the second embodiment of the present invention. As the second embodiment, the most different from the first embodiment is the cylindrical body 31 and the upper portion of the holding member 15. Instead of the plate 32, a conical cylindrical body 35 is provided, and a tapered surface 19 that guides the shaft 12 to the female screw hole 18 is formed on the inner surface of the conical cylindrical body 35.
Thus, by forming the tapered surface 19 that guides the shaft 12 to the female screw hole 18 of the presser member 15, the positions of the female screw hole 18 and the male screw groove 13 are both checked when the presser member 15 is screwed. Therefore, it is possible to simplify the surface matching and improve the working efficiency.
Further, as shown in FIG. 2, in the second embodiment, a tapered portion 12a may be provided further on the distal end side of the male screw groove portion 13 in the shaft 12, and the female screw hole portion 18 is formed by the tapered portion 12a. And the alignment of the male screw groove 13 is further facilitated.

As described above, the tile body T according to the present invention may have any surface such as hard, semi-rigid, and soft. However, if the surface is soft, the tile construction jig 10 includes the bottom plate 11 and In addition to the presser member 15, a washer member 41 that is sandwiched between the adjacent tile body T and the presser member 15 and is fitted to the shaft 12 may be provided (see FIG. 2).
Thereby, it is possible to prevent wrinkles and dents on the surface of the soft tile body T, and even when the surface of the tile body T is soft and the friction coefficient is large (that is, the contact surface 14 of the pressing member 15 is difficult to slip), There is no problem in twisting and tightening of the presser member 15.
Further, in the washer member 41, the inner diameter of the inner hole 41 a fitted into the shaft 12 is slightly larger than the plate width W of the flat plate portion 16, and the contact surface 14 becomes the washer member when the presser member 15 is twisted. It is difficult to deviate from 41.
Other configurations, operational effects, and usage modes of the tile construction jig 10 are the same as those in the first embodiment.

FIG. 3 shows a pressing member 15 of a tile construction jig 10 according to the third embodiment of the present invention. In this third embodiment, the most different point from the first and second embodiments is that of the pressing member 15. The nut member 42 is formed on the upper surface.
An engaging torque wrench or an electric screwdriver may be used for the nut member 42, and the lever principle can be used for tightening (twisting) the presser member 15, thereby reducing the tightening load.
Further, even when a plurality of tile construction jigs 10 are used, the tightening of each construction jig 10 to the tile body T can be adjusted with a torque wrench, or the tiles between the construction jigs 10 can be adjusted with an electric driver capable of torque adjustment. By adjusting the tightening torque of the body T to a predetermined value, the degree of tightening of the tile body T by the plurality of tile construction jigs 10 can be stabilized.

In addition, the nut member 42 can be integrally formed by a mold together with the presser member 15 so that the manufacturing efficiency can be improved and the cost can be reduced. Further, a separate nut member 42 may be attached to the presser member 15.
The hole formed in the nut member 42 may be a wrench hole 43 into which a hexagon wrench can be inserted, or the female screw hole 18 in the presser member 15 may be extended. Further, a slot for a minus driver or a plus driver may be formed on the upper surface of the nut member 42.
Furthermore, a user can attach a wrench that engages with the nut member 42, a hexagon wrench that can be fitted into the wrench hole 43, or the like to one end of a long rod-shaped member, or the hexagon wrench itself can be formed into a long shape. The surface of the adjacent tile body can be flattened without bending.
Other configurations, operational effects, and usage modes of the tile construction jig 10 are the same as those in the first and second embodiments.

In addition, this invention is not limited to embodiment mentioned above. Each configuration of the tile construction jig 10 or the overall structure, shape, dimensions, and the like can be appropriately changed in accordance with the spirit of the present invention.
The tile construction jig 10 was used when constructing the tile body T on the floor surface. Naturally, the tile construction jig 10 is not limited to the floor surface, and an adhesive is applied to the casing on the wall surface or the ceiling. After placing the bottom plate 11 and the tile body T in this order, the tile body T may be aligned by tightening with the pressing member 15.

In addition, the tile construction jig 10 may be used not only for matching two adjacent tile bodies T but also at a place where the four tile bodies T meet.
At this time, as described above, if the separation portion 17 can prevent excessive twisting off of the shaft 12 due to twisting of the holding member 15, the separation portion 17 has a narrow neck shape (for example, a shaft). The bottom plate 11 may be swingable with respect to the shaft 12 as a notch having a length in the radial direction L of 12 and a length in the radial direction L longer than the diameter D of the male screw groove 13. .
At this time, the flat plate portion 16 comes into contact with the two tile bodies T whose side end faces are directly opposed to each other among the four tile bodies T to be brought together, thereby preventing the bottom plate 11 from being rotated.

Furthermore, if the tile construction jig 10 can prevent the shaft 12 from being twisted off and the bottom plate 11 from being twisted by twisting of the holding member 15, the tile construction jig 10 is made of a material other than the above-described thermoplastic resin such as plastic. For example, the entire pressing member 15 may be made of metal, or may be configured by insert molding in which a metal nut is incorporated only into the female screw hole portion 18 of the pressing member 15.
Thus, by using a metal for the pressing member 15, the strength is improved and it is easy to use a plurality of times.
Further, the shaft 12 of the bottom plate 11 may be configured by insert molding using the male screw groove portion 13 as a metal bolt, and the strength is increased by using the metal partially or entirely, and the torsion and tightening are strengthened. Yes.

Although the bottom plate 11 has a disc shape, the shape is not particularly limited as long as the adjacent tile body T can be supported from the back surface side. For example, the bottom plate 11 has a triangular shape, a rectangular shape, or a polygonal shape of a pentagon or more. Also good.
This also applies to the planar shape of the pressing member 15. The planar shapes of the cylindrical body 31, the upper plate 32, and the upper pillar body 33 in the pressing member 15 may be circular as described above, but the adjacent tile bodies T Can be pressed from the surface side, for example, a triangular shape, a rectangular shape, or a polygonal shape such as a pentagon or more may be used.

Further, the bottom plate 11 is not provided with a hole or the like penetrating the bottom plate 11 in the thickness direction, but such a through hole may be formed.
If the flat plate portion 16 is provided on the shaft 12 between the male screw groove portion 13 and the bottom plate 11 (that is, the connecting portion between the lower end of the male screw groove portion 13 and the upper surface of the bottom plate 11), the entire connecting portion is flat ( It may not be the flat plate portion 16), and a part of the connecting portion may be the flat plate portion 16.

  The present invention is not limited to floors, walls, and ceilings in buildings, but is used as a jig to bring the surfaces of adjacent tile bodies into a flush state when tiles are applied to outdoor fences, exteriors of installed objects, etc. It can be used.
