Description

  The present invention relates to a floor tile construction method.

  Conventionally, when installing a floor tile, an adhesive mortar is used to adhere the floor tile to the foundation concrete. Moreover, since the adhesive strength of the floor tile with respect to foundation | substrate concrete can be raised, the case which uses an organic adhesive instead of sticking mortar is increasing.

  On the other hand, when unevenness (unevenness) is generated on the surface of the ground concrete, it is necessary to apply a ground surface adjusting material in advance. In some cases, the floor tiles peeled off due to insufficient adhesion between the mortar and the adhesive mortar and organic adhesive.

  On the other hand, a method has been put to practical use in which irregularities / backs are provided on the adhesive surface of the floor tile, and the floor tile is adhered to the surface of the underlying concrete via affixed mortar. In this construction method, it is not necessary to adjust the unevenness only with the unevenness adjusting material / underground adjustment layer such as organic materials, and the thickness necessary for the unevenness adjustment between the ground concrete and the floor tile is covered by pasting mortar. (For example, refer to Patent Document 2).

  Here, by using the conventional floor tile construction method, it is possible to suitably construct a 900 × 150 mm floor tile, but in this construction method, the filling properties of the floor tile and the pasting mortar are important, When constructing a large floor tile with a short side exceeding 300 mm, as shown in FIG. 2, there is no escape route for the air (gap P) between the floor tile 1 and the base concrete 2, and the mortar is applied. There was a possibility that the filling rate of 3 might fall.

  Further, some floor tiles 1 are slightly warped by firing, and there is a case in which the gap P remains in the vicinity of the center of the floor tile 1. And the space | gap P which remained between the floor tile 1, the ground concrete 2, and the sticking mortar 3 becomes a factor which produces the crack of the floor tile 1 by an impact.

On the other hand, at the time of construction, in general, the floor tile in the middle of application is peeled off or the filling property is checked by hitting sound to check the filling property / remaining gap. However, when the tile size is larger than 0.5 m ² , it is not easy to remove and inspect. In addition, when the affixed mortar is in an uncured state, it is difficult to confirm the filling state of the affixed mortar on the back side of the tile by a hammering inspection or the like.

For this reason, for example, even when constructing a large floor tile with an area exceeding 0.5 m ² and a short side exceeding 300 mm, the back side fillability is accurate without peeling off the floor tile. There has been a strong demand for a technique that can be confirmed well and that allows floor tiles to be constructed more suitably.

  In view of the above circumstances, the present invention provides a method for constructing a floor tile that enables efficient and reliable confirmation of the filling property of the back surface and enables suitable construction even for large floor tiles. For the purpose.

  In order to achieve the above object, the present invention provides the following means.

  The floor tile construction method of the present invention is a method of pasting a floor tile to a surface to be pasted via a pasting material, and damming between the surface to be pasted and an outer peripheral end side of the floor tile. The floor tile is disposed on the surface of the object to be pasted while interposing a part, and a filling space is formed between the surface of the object to be pasted and the back surface of the floor tile by the damming part, and the filling Forming an inlet and a plurality of outlets for communicating the space and the outside, injecting a sticking material into the filling space from the inlet, and completing the injection when the sticking material flows out of the plurality of outlets It is characterized by.

In the floor tile construction method of the present invention, a sticking material such as mortar is post-injected. This method is more time-consuming than the conventional method of retrofitting floor tiles. For example, when applied to the construction of large floor tiles with an area exceeding 0.5 m ² , it is in the out-of-plane direction. Overall, it is possible to achieve more efficient and effective construction than the back-tensioning method, including height adjustment and ensuring and confirming the filling property of the back surface of the floor tile.

  Therefore, according to the floor tile construction method of the present invention, even if it is a large floor tile, it is possible to confirm the filling property of the back surface efficiently and reliably and to perform construction suitably.

It is a figure which shows the construction method of the floor tile which concerns on one Embodiment of this invention. It is a figure which shows the state in which the space | gap remained between the floor tile, foundation concrete, and affixed mortar.

  Hereinafter, with reference to FIG. 1, the construction method of the floor tile which concerns on one Embodiment of this invention is demonstrated.

The present embodiment relates to a method for constructing a floor tile that enables suitable construction of, for example, a rectangular flat floor tile, and particularly, for example, when constructing a large floor tile having an area exceeding 0.5 m ^2. It is related with the construction method of the floor tile which can confirm the filling property of a back surface, without peeling a floor tile.

  Specifically, in the floor tile construction method of the present embodiment, first, a predetermined organic adhesive is applied to the adhesive surface / back surface of the floor tile. This step can be omitted.

  Further, as shown in FIG. 1 (a), an organic adhesive 5 is applied in a frame shape along the outer peripheral end portions on the four outer peripheral end portions of the back surface 1a of the floor tile 1, and a damming portion 6 is formed. Form. At this time, the organic adhesive 5 is applied in a discontinuous manner, and the damming portion 6 is formed so that the gaps H are formed at the corners of the four corners of the floor tile 1.

  Next, as shown in FIG.1 (b), the organic type adhesive agent 5 is apply | coated to the predetermined position of the surface of the foundation concrete (application object) 2. As shown in FIG.

  And as shown in FIG.1 (c), the floor tile 1 is mounted in the predetermined position of the surface of the foundation concrete 2 so that the organic adhesive 5 apply | coated to the surface of this foundation concrete 2 may be interposed in between. . Further, the floor tile 1 is placed on the surface of the ground concrete 2 and the height in the out-of-plane direction is adjusted. At this time, in this embodiment, the frame-shaped damming portion 6 provided on the back surface 1a of the floor tile 1 serves as a frame, and the height can be easily adjusted.

  Here, for example, the damming portion 6 may be formed using affixed mortar 3 or a resin material (high foaming sponge, low foaming backer, rubber material, etc.), and in particular, the material forming the damming portion 6. There is no need to limit. Alternatively, the damming portion 6 may not be provided integrally with the back surface 1a of the floor tile 1 in advance, but the damming portion 6 may be installed on the surface of the foundation concrete 2 and the floor tile 1 may be placed thereon.

  Next, as shown in FIGS. 1 (d) and 1 (e), one gap H formed at the four corners of the floor tile 1 is used as an injection port H1, and an injection plug 7 is installed in the injection port H1. . The area around the injection plug 7 is closed with an organic adhesive so that a gap is not formed.

  Next, the sticking mortar (sticking material) 3 that is softly kneaded to the level of self-leveling is poured into the filling space between the ground concrete 2 and the floor tile 1 formed by the damming portion 6 from the inlet H1. In the case of the large floor tile 1, a sufficient injection pressure is applied to the end of the floor tile 1 by increasing the injection height or the like.

  Next, when the pasted mortar 3 overflows from the outlets H2, H3, H4 in the gaps H at the remaining four corners of the floor tile 1, the outlets H2, H3, H4 are sequentially closed with an organic adhesive or the like. . In addition, as long as the inlet H1 and the outlets H2, H3, and H4 can be closed, the material for closing may not be specifically limited. For example, when the pasting mortar 3 and the organic adhesive are mixed and it is difficult to perform the construction, a cured product (such as modified silicone) of the same material as the organic adhesive may be sandwiched.

  And as shown in FIG.1 (f), when three injection holes H2, H3, and H4 are obstruct | occluded sequentially and injection | pouring of the sticking mortar 3 stops, the sticking mortar between the floor tile 1 and the ground concrete 2 is stopped. 3 is completely filled.

Therefore, in the floor tile construction method of this embodiment, the pasting mortar 3 is post-injected as described above. This method is more time-consuming than the conventional method of retrofitting the floor tile 1, but for example, when applied to the construction of a large floor tile 1 having an area exceeding 0.5 m ² , Overall, it is possible to realize construction that is more efficient and effective than the back tension method, including adjusting the height in the outward direction and ensuring and confirming the filling property of the back surface 1a of the floor tile 1.

  Therefore, according to the floor tile construction method of the present embodiment, even the large floor tile 1 can confirm the filling property of the back surface 1a efficiently and reliably and can be suitably constructed. .

  Moreover, if the floor tile construction method of this embodiment is applied to a construction method that uses an organic adhesive having an easy-to-handle viscosity (high viscosity, high thixotropy) as in Patent Document 2, the damming portion 6 is shaped like a frame. It is possible to easily perform troublesome work such as forming or pushing in a little to reduce the height. Furthermore, since the height adjustment work can be completed prior to the pasting mortar construction, the accuracy in the out-of-plane direction can be remarkably improved. Furthermore, for example, if the sticking mortar 3 having a low viscosity is used, it is possible to improve the workability / workability as compared with the post-stretching method.

  As mentioned above, although one Embodiment of the construction method of the floor tile which concerns on this invention was described, this invention is not limited to said embodiment, In the range which does not deviate from the meaning, it can change suitably.
