Description

  The present invention relates to a construction method and a structure thereof, in which a floor tile obtained by molding and baking a flat stone or clay in a flat shape on a floor of a building is attached to a frame floor.

  Conventionally, floor tiles are constructed by a wet method in which a ground layer of a ground mortar is formed on a concrete frame and is pasted with a mortar. In some cases, the base mortar may be directly pasted on the concrete frame without forming the base layer.

  In recent years, a dry construction method in which a resin adhesive is used instead of the adhesive mortar has been adopted.

The floor tile construction method in which a wet method is applied to a concrete frame or base mortar has the following drawbacks.
I. Cracks in floor tiles due to shrinkage cracks and structural cracks in reinforced concrete that occur in the case of the wet method where tiles are pasted with mortar.
B. Cracks in floor tiles due to dry shrinkage cracks in affixed mortar.
C. The construction speed is slowed by the time required to prepare, knead, and apply the adhesive mortar.
D. The time required for complete curing of the mortar is as long as about 4 weeks, and the overall construction period of the building is also extended.
E. The floor tiles must be jointed on site one by one, which takes time.
F. The weight of the mortar to which the floor tile is attached is added to the weight of the entire floor, resulting in an increase in the weight of the floor and, consequently, the earthquake resistance of the building.
G. The floor and the building are soiled by the soiling of the building due to the mortar applied by the wet method and the soiling of the floor due to the overhanging mortar.
H. In both the wet method and the dry method, floor tiles must be jointed on the spot one by one, and it is difficult to keep the joint spacing constant, and the joints cannot be kept in order.
Li. As for the flatness of the floor, it is necessary to match the thickness of each floor tile in the field, and the flatness of the floor surface is lowered.
Nu. It is difficult to replace floor tiles, and it is impossible to replace dirty floor tiles with new floor tiles without damaging them. Therefore, old floor tiles cannot be recycled by washing and resources cannot be used effectively.
The present invention has been invented to solve these drawbacks.

As a result of intensive studies in view of the above situation, the present inventor has made the invention as described below.
The floor construction material 1 is laid on the floor surface before the floor tiles 5 made of flat stones and clay are molded and fired on the floor of the building. The floor construction material 1 has a thickness of 1 mm to 40 mm, and the planar shape of the floor construction material 1 is the same as the planar shape of the floor tile 5 to be attached. Concavities and convexities are formed in the four corners or sides of the floor construction material 1 so as to join the floor construction materials 1 to each other in a planar shape, and a plurality of floor construction materials 1 are fitted and joined to each other. . Position fixing projections 2 smaller than the thickness of the floor tile 5 for fixing the position of the floor tile 5 are provided on at least two sides of the surface of the floor construction material 1. By inserting and fixing the floor tiles 5 into the recesses formed by the position fixing protrusions 2 on the surface of the plurality of floor construction materials 1 that are fitted and joined in a flat shape at four corners or four sides of the floor construction material 1. A floor tile surface is constructed.
After the floor tiles 5 are laid, the joints of the floor tiles 5 are also formed by inserting and fitting rod-shaped joint materials into the protrusions for fixing the position of the floor tiles 5. The joint rod 6 is provided with a joint rod 6 fitting projection linearly downward. The position fixing projection 2 of the floor construction material 1 is formed with a projection concave portion on the upper side, and is fitted to the joint rod 6 fitting projection to fix the joint rod 6.
A plurality of floor construction materials 1 may be formed into a sheet shape so that a plurality of floor tiles 5 are integrally joined and a plurality of floor tiles 5 are inserted and fixed.
Before the floor tile 5 is inserted and fixed to the floor construction material 1, an adhesive is applied to the floor tile 5 or the surface of the floor construction material 1, and the floor tile 5 and the floor construction material 1 are bonded and fixed. The fixing of the tile 5 can be strengthened.
After laying one or more floor construction materials on the floor surface, in order to fix the floor construction material 1 to the ground floor concrete surface, a plurality of fixing screws are driven in from above the flat part, or bonded with an adhesive. It fixes to the ground concrete surface by fixing.

By using the present invention. Prevention of cracking of floor tile 5 due to shrinkage cracking of structural concrete, structural cracks, and drying shrinkage cracking of pasted mortar, which occurs in the case of the wet method where conventional floor tiles 5 were pasted with pasting mortar Is done.
In addition, the construction speed is increased by eliminating the trouble of preparing, kneading, and painting the pasting mortar. Furthermore, the time for curing the mortar is eliminated, and the entire construction period of the building is shortened. By laying the floor tile 5 on the floor construction material 1, the jointing process of the floor tile 5 is omitted, so that the construction is further simplified and the construction period is shortened.
On the other hand, the weight of the entire floor is reduced by eliminating the mortar attached to the floor tile 5, the weight of the floor is reduced, and the seismic performance of the building is improved.
In addition, the building is prevented from being soiled by the mortar applied by the wet method, and the mortar does not protrude and the floor and the building are not soiled. By fitting the floor tiles 5 to the floor construction material 1, the joint spacing can be kept constant, and the joint streets are kept orderly and a floor is provided. As for the flatness of the floor, by placing it on the floor construction material 1 produced in the factory, there is no matching of the thickness of each floor tile 5 in the field, and the floor surface becomes less uneven. Improves flatness. Further, according to the present construction method and structure, it is easy to replace the floor tile 5, and the dirty floor tile 5 can be easily replaced with a new floor tile 5. On the other hand, the old floor tile 5 can be recycled by washing, so that resources can be saved. Effective utilization is promoted.
