[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor tile panel suitable for construction of a building slab and the like, a floor body using the same, and a construction method thereof.

[0002]

2. Description of the Related Art In a method of constructing a floor slab of a building with tiles or tile panels, in the former case, tiles are attached one by one to a slab surface by mortar, and in the latter, a plurality of tiles are previously formed into a unit as a unit. The panel attached to the slab is laid on the slab surface.

A tile panel used for such a floor slab has a structure in which a fixed number of tiles are attached to an upper surface of a concrete base formed to a fixed size at a factory manufacturing stage. The base is generally formed to have a uniform thickness so as to have a uniform strength as a whole, and a base having a uniform flat surface is also used.

On the other hand, in place of construction using tile panels,
For example, as described in JP-A-8-82073, receiving girders are connected in a grid pattern to a plurality of supporting legs arranged on a floor slab, and a floor panel is placed on these receiving girders. Those arranged in a row are also used in a wide range of fields.

[0005]

However, since most of the slab surface of a building remains a concrete casting surface, unevenness and waving of the surface are often generated. Therefore, if the tile panel is laid after the mortar is cast, the orientation of the tile panel will also be uneven due to such unevenness of the surface of the slab surface and waving, etc., and if the mortar solidifies as it is Such irregularities remain as a history, and the construction surface of the tile panel is likely to be defective.

[0006] Therefore, conventionally, before laying a tile panel, a mortar in which moisture is reduced with respect to cement is applied to the slab surface, the tile panel is temporarily placed thereon, and the mortar is pressed from above by pressure. The mortar is used to absorb irregularities and undulations on the slab surface. Then, remove the tile panel, pour the cement paste into the laying surface,
The work of arranging the tile panels again is performed.

However, in such a construction procedure,
Tile panels with a concrete base as a base are heavy, making it difficult to handle from factory shipment to on-site construction. The influence of is large.

[0008] As described above, the conventional tile panels are poor in workability due to their large weight, and the labor and complexity of work due to the difficulty in uniformly constructing a large number of tile panels at the same level. large.

The problem to be solved in the present invention is to provide a floor tile panel and a method of constructing a floor tile which can be reduced in weight to improve the workability and obtain a good construction body without unevenness in height and posture between panels. To provide.

[0010]

SUMMARY OF THE INVENTION The present invention relates to a floor tile panel including a panel body fixed to a floor surface using mortar as a bonding agent and a tile disposed on the upper surface thereof, wherein the mortar is provided on the bottom surface of the panel body. The convex portions forming the joint surface with the substrate are arranged in a substantially uniform pattern.
In this case, the panel body is molded from concrete,

In the floor of the present invention, mortar is cast on the floor in a substantially uniform pattern, the panel body is placed on the mortar, and the height of the panel is adjusted by being erected on the floor. The lower surface of the tile panel is received by the support.

Instead of such a floor, a convex portion arranged in a substantially uniform pattern is formed on the bottom surface of the panel body, and mortar is applied to the floor surface in accordance with the arrangement of the convex portion of the panel body. The mortar may be mounted on the mortar, and the lower surface of the tile panel may be received by a height-adjustable supporter standing on the floor.

Further, according to the construction method of the present invention, the support provided with the receiving block which can be raised and lowered from above is arranged at a position along the edge of the panel main body, and the upper end of the receiving block is set so that the panel main body is higher than its finishing level. It is set to be high, and mortar is cast on the floor in accordance with the arrangement of the projections of the panel body, and before the mortar hardens, a joint is provided between adjacent panel bodies to form projections. The height and posture of the panel main body are adjusted by landing on the mortar and placing the lower surface of the panel main body on the receiving block, and operating the receiving block including a part thereof at the joint from above to adjust its level. It is characterized by adjusting.

1 is a plan view of a tile panel according to the present invention, and FIG.
FIG. 1 is a longitudinal sectional view taken along line AA in FIG. 1, and FIG. 3 is a perspective view seen from the bottom surface side. In this embodiment, a case is shown in which the projections are provided substantially uniformly on the bottom surface of the panel body.

In the figure, a tile panel 1 has a square planar shape as a whole and is formed as a laminate of a panel body 2 joined to a laying surface by mortar and a plurality of tiles 3 arranged on the upper surface thereof. It is.

The panel body 2 is made of, for example, PC, GRC, C
This embodiment uses a concrete product such as FRC and has a plate portion 2a having a uniform thickness on its surface and a lattice-like rib 2b as shown in FIG. 3 on the lower surface of the plate portion 2a. Are formed as protrusions. In the illustrated example, the length of one side of the panel body 2 is 600
mm, and the thickness of the plate portion 2a is 15 mm.
The rib 2b is formed in a shape of drawing a square with a side length of 150 mm by the division line at the lower end, and the thickness of the rib 2b is also 15 mm.

The tiles 3 are bonded to the panel body 2 with an adhesive or mortar, and are arranged with joints 3a having a uniform width between the tiles 3 as shown in FIG. .

FIG. 4 is a longitudinal sectional view showing a main part when the tile panel 1 is installed on the floor surface.

The floor 4 is a slab having irregularities and wavings while the concrete is being cast. The floor 4 is used for adjusting the level and posture of all the tile panels 1 with respect to the floor 4 and for supporting the load. The support 5 is previously installed on the floor 4. These supports 5 are arranged, for example, at four corners of the square tile panel 1 shown in FIG. 1 and one support including the tile panel 1 adjacent to the four sides. It is assumed that the tool 5 receives one corner of the four tile panels 1. In addition, a layout may be provided at an intermediate position between each side of the tile panel 1 to support two adjacent tile panels 1.

FIGS. 5A and 5B show details of the support structure of the tile panel 1 by the support tool 5, wherein FIG. 5A is a longitudinal sectional view and FIG. 5B is a plan view of a main part.

The support 5 is a base 5 mounted on the floor 4
a and a receiving block 5c screwed into a sleeve 5b having the female thread. The receiving block 5c is formed in a disk shape and has a tool groove 5c-1 at the center thereof for receiving a driver. With such a support 5, as shown in FIG. 5 (a), a gap substantially equal to the joint 3a of the tile 3 is arranged between the tile panels 1 so that the center of the receiving block 5c is a gap. If it is located in the tool groove 5c-1
Can be hung. Therefore, receiving block 5c
By turning, the height with respect to the base 5a can be changed, and the level of the tile panel 1 with respect to the floor 4 can be adjusted.

FIGS. 6A and 6B show another two examples of the support member 5, and FIGS. 6A and 6B show the support member 5 screwed to a sleeve 5b of a base 5a which is a member common to the previous example. Bolt shaft 5
a square receiving block 5e at the upper end of the bolt shaft 5d
It is mounted so as to be rotatable around and has a slip washer 5f interposed on the lower surface of the receiving block 5e.

Also in this example, a tool groove 5d-1 for tool engagement is provided on the upper end surface of the bolt shaft 5d, and the bolt shaft 5d can be moved up and down by turning it with a screwdriver. The level of 5e can be changed. Since the receiving block 5e can rotate with respect to the bolt shaft 5d, even if the weight of the tile panel 1 is loaded on the upper surface of the receiving block 5e, the bolt shaft 5d rotates independently of this, so that the level can be easily adjusted. Can be.

FIGS. 6C and 6D show a bolt-shaped base 5g screwed with a bolt shaft 5h, and a receiving block 5i is rotatably mounted on the upper end of the bolt shaft 5h. Is provided with a tool groove 5h-1 at the upper end thereof. In this example, the base 5g is not in surface contact, and only the lower end surfaces of the pair of sides are seated on the floor surface 4. Therefore, the influence of irregularities on the surface is reduced, and the base 5g can be easily maintained in a stable posture. .

After the support 5 is set at a predetermined position on the floor 4, a mortar 6 is cast on the floor 4. The mortar 6 is a rib 2 on the back surface of the panel body 2 shown in FIG.
It is to be laid in a grid on the floor 4 in accordance with the position of b, and its thickness is such that it can sink a little when the tile panel 1 is placed and can receive the lower surface of the plate portion 2a by the support 5. And

After the mortar 6 is cast, the tile panel 1 is placed on the mortar 6 whose ribs 2b are laid in a lattice pattern, and the tile panel 1 is placed between the tiles 3 of the adjacent tile panel 1 as shown in FIG. It arranges so that the joint 1a may be formed. As a result, the plate portion 2a of the panel body 2 is
As shown in (1), the corners of the four corners rest on the supports 5, and the tile panel 1 is supported by these supports 5 and the mortar 6. After the mortar 6 is cured, the joints 1a between the tile panels 1 are filled with joint mortar or sealing.

Here, the support tool 5 has two roles of supporting the load of the tile panel 1 until the mortar 6 hardens and adjusting the level of the tile panel 1 when the tile panel 1 is applied to the floor surface 4. do.

That is, the tile panel 1 is placed on the mortar 6 while the mortar 6 is cast and the mortar 6 does not harden. Therefore, if the mortar 6 is in a soft period, the tile panel 1 gradually sinks by its own weight. Go out. On the other hand, by receiving the tile panel 1 with the support 5, the load of the tile panel 1 can be received by the support 5 during the period until the mortar 6 is completely cured, and the tile panel 1 sinks. There is no construction possible. As described above, since the tile panel 1 is received and supported by the support 5, the load on the mortar 6 can be reduced. Therefore, even if the mortar with reduced moisture is not applied to the entire panel body 1, the ribs can be provided. The mortar 6 can be cast such that only the portion 2b is spotted.

Even after the tile panel 1 is laid,
Joint 1 between tile panels 1 as shown in FIG.
Since a screwdriver can be mounted on the tool groove 5c-1 of the receiving block 5c from a, the height of the tile panel 1 can be adjusted by turning the receiving block 5c. By arranging the supports 5 at least at four corners of one tile panel 1, the posture of the tile panel 1 can be adjusted by adjusting the height of each of the supports 5. Therefore,
The work of adjusting the level of the tile panel 1 and modifying the setting of the posture can be easily performed. Furthermore, at the time of such height adjustment, it is not necessary to cut out the edge of the tile in order to install a screwdriver in the tool groove 5d-1,
Even after the construction, the appearance of the tile panel 1 is not spoiled.

In the construction of such a tile panel 1, the ribs 2b of the panel main body 2 are formed in a grid as shown in FIG. 3 and the mortar 6 is cast on the floor 4 so as to correspond to the grids. The entire thickness does not need to be equivalent to, for example, the rib 2b in the illustrated example, and the entire tile panel 1 is reduced in weight. Therefore, handling from the factory shipment to the site transfer and construction is simplified, and the work load is reduced.

Further, since the tile panel 1 is received by the support member 5 and the amount of settlement on the floor 4 can be regulated, the mortar 6 in the form of paste is directly cast on the floor 4 and then the tile panel 1 is removed. Laying work can be started. For this reason, there is no need to perform any other work such as arranging the tile panels again after absorbing the unevenness and waving of the floor surface by temporarily placing them as in the conventional case, and the workability is significantly improved.

Further, the support 5 only needs to have a function of maintaining the tile panel 1 at an appropriate height and posture during the period until the mortar 6 is hardened. The load is supported by the mortar 6. Therefore, the mortar 6 bears the loaded load after construction, and the support 5 does not need to be designed in consideration of the load applied to the tile panel 2, that is, the load including the loaded load. For this reason, the support member 5 can be configured with simple members as compared with the support legs and the like used in the conventional double floor structure and the like, and the cost can be improved.

Further, since the support member 5 can be arranged to receive the lower surface of the plate portion 2a, the finished surface of the tile panel 1 from the floor surface 4 can be made thinner. That is, since the height of the support 5 is adjusted by moving the receiving block 5c up and down with respect to the tile panel 1, it is necessary to have a structure having a bulk in the vertical direction. Therefore, if the support 5 is brought into contact with the plate 2a at a position recessed above the rib 2b when viewed from the floor surface 4 side, the vertical bulk of the support 5 can be absorbed. Thereby, the height of the finished surface of the tile panel 1 with respect to the floor surface 4 is reduced. For this reason, compared with the conventional double floor structure, it is possible to set the finished floor surface lower than the surface where the slab or the like is cast, and to perform the construction without wasting the space of the building.

Here, in the embodiment, the convex portion is a rib 2b having a lattice shape. However, instead of this, for example, only a portion where the ribs 2b orthogonal to each other intersect is scattered as a convex portion, or a circular portion is formed. May be arranged in a staggered manner.

The panel body 2 has ribs 2b as projections.
In place of the mortar 6, the mortar 6 to be applied to the floor 4 is arranged in a grid pattern similar to the rib 2b shown in FIG. It is also possible to adopt a configuration in which it is arranged to be placed on a. In this case, if the supporting members 5 are arranged as in the above-mentioned example so that the edge of the panel main body 2 is not covered on the grid-like mortar 6, the panel main body 2 after the mortar 6 is constructed. The height adjustment can be performed in the same manner by the temporary placement and the support 5.

[0039]

According to the floor tile panel of the present invention, by reducing the weight of the tile panel, handling from factory shipment to construction on site can be facilitated, and workability can be improved.

Further, in the floor body using the floor tile panel and its construction, the level of the panel body is adjusted by receiving the panel main body with the support tool. If the adjustment work is performed when the floor is landed, the panel body can be laid correctly by hardening the mortar, and it is not necessary to lay the tile panel again after temporarily placing it as in the past, and the workability is dramatically improved improves.
