Abstract

To suppress the generation of a gap between tatami rooms, the gap between tatami rooms may be caused by warping of wood or by shrinkage of the tatami. Here, in order to suppress the generation of gaps due to the shrinkage of the tatami mat, the heat insulating foam that causes the shrinkage of the tatami mat is not used as it is, but it is sewn after cutting to a width of 5 cm and the shrinkage force is transmitted to other components. I tried not to. As a result, the shrinkage of the tatami mat is minimized, and no gaps are generated in the room.

Description

The present invention relates to a tatami core and a tatami mat.

In the conventional technique, the gap generated in the tatami room has been dealt with by repairing it once every several years.

The gap generated in the room of the tatami may be caused by warping of the wood in the room or by shrinkage of the tatami. If the latter is the cause, it can be solved and improved by this device. The shrinkage of the tatami occurs in the ratio of the vertical direction 2: the horizontal direction 1. This is because the polystyrene foam in the components of the tatami mat shrinks when used for many years. In the present invention, the shrinkage property of the polystyrene foam is not transmitted to other components, and finally the shrinkage of the tatami mat itself is prevented.

Means to solve the problem

The present invention cuts polystyrene foam, which is the cause of tatami mat shrinkage, to a width of 5 cm. Then, place them in the same state, sandwich the top and bottom with an insulation board, and sew them at a thread spacing of 6 cm. The cut surface is stabilized when 24 wefts are sewn in the vertical direction at 30 or more locations. In addition, by inserting granular charcoal such as bamboo charcoal or activated carbon into the cut surface, charcoal can be folded without squeaking noise.

Best mode for carrying out the invention

Embodiments of the present invention will be described with reference to the drawings. [FIG. 1] is a cross-sectional view of a tatami mat in which polystyrene foam (2) is sandwiched between insulation boards (1) and sewn with thread (3). [FIG. 2] is a cross section in which [FIG. 1] shrinks after several years. The polystyrene foam in the middle is clearly stepped and shrunk, but this shrinking force is transmitted to the upper and lower insulation boards, and the entire tatami mat is shrunk. [FIG. 5] is a plan view in which 8 tatami mats are laid, and represents a place where a gap is generated. FIG. 3 is a sectional view of a tatami mat according to the present invention, in which a polystyrene foam is cut to a width of 5 cm and sewn to an insulation board with a thread. [FIG. 4] is a cross-sectional view in which the shrinkage occurs in the polystyrene foam after several years in [FIG. 3]. Although the shrinkage causes a gap in the interior, the thread sewing interval is larger, so the insulation It is a diagram showing that the generation of tatami mat shrinkage can be minimized because no contraction force is applied to the board. [FIG. 6] shows a case where bamboo charcoal and activated carbon (5) are further placed between the cut polystyrene foams.

Effect of device

If this invention is used, the gap which arises in a tatami room can be minimized, and the unsanitary environment where dust, dust, etc. can accumulate can be eliminated. Furthermore, a healthy living space can be maintained by the effect of bamboo charcoal and activated carbon.

It is a finished sectional view of a tatami mat sandwiched with polystyrene foam with an insulation board and sewn with thread. It is sectional drawing shrunk when the thing of FIG. 1 passed several years. It is the finishing sectional drawing of the tatami which cut | disconnected the polystyrene foam. It is sectional drawing shrunk when the thing of FIG. 3 passed several years. It is a top view between 8 tatami mats in a general manner. It is sectional drawing of what put bamboo charcoal and activated carbon in the cut surface of a polystyrene foam.

Claims (2)

By cutting the polystyrene foam, which is a heat insulating material and the core material of the tatami mat, into a width of 5 cm, and then remolding it, the tatami mat does not give shrinkage to other components (insulation board, etc.) while taking advantage of the heat insulating properties. Tatami with minimal overall shrinkage The tatami mat according to claim 1, wherein the living environment can be further improved by putting granular charcoal such as bamboo charcoal and activated carbon into the cross section for re-molding the cut polystyrene foam.
