Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating floor structure installed in a building such as a house or office.

[0002]

2. Description of the Related Art Conventionally, for example, a combination of a floor material for floor heating of a building such as a house or office and a heat generating member (electric heating material, hot water pipe, etc.) is roughly divided into a heat generating member separation type and a heat generating member. There is an integrated type.

The heat-generating member-separated type is a heat-generating panel having a heat-generating member incorporated therein which is laid on the floor base material or between joists and is a separate body from the heat-generating panel laid on the heat-generating panel. It is composed of floor materials. In this heat generating member separation type, since the heat generating panel and the floor material are separate bodies as described above,
The higher the degree of freedom in selection of each type and size, and the larger the area of the heat generating panel, the greater the ratio of heat generating parts to the total area, and the less the connecting parts of heat generating members, the easier the construction. And, it has the advantage that there are few failures.

However, this heat generating member separation type is
It has the following drawbacks. (A) Damage to the heat-generating member due to nailing If the position and direction of nailing are incorrect, the heat-generating member, temperature control device, connector, etc. will be damaged, causing electric leakage, water leakage, and other troubles. (B) It is difficult to replace only the floor material, and it is possible to replace only the non-reusable floor material. However, since it is fixed with nails and adhesive at the time of installation, it takes a lot of labor and time to remove it. Moreover, complete removal is difficult. At that time, the floor material and the heat generating panel are damaged by the nails (bars) and scraper blades, so reuse and reuse are not possible.
Also, the waste material is dangerous because the nails are exposed. (C) It is necessary to replace the floor material only when the heating panel fails. When repairing the failed heating panel, it is necessary to remove the floor material. Therefore, there is a problem shown in (a). (D) Difficult to change the heating area after installation It is impossible to change the heating area after installation because of the reason (b) above. Therefore, if it is expected that the heating area will be partially changed by changing the floor plan such as moving furniture, it is desirable to install heat-generating panels up to the part where heating is not required for the time being. (E) Generation of squealing noise (squeaking noise) When the heat generating panel / floor material expands / contracts / curves and changes in the gap, squeaking noise (squeaking noise) may occur. If a squealing noise is generated,
There is a problem of (a). (F) Noise during construction When fixed to joists, there are many nailing points with a hammer and nailing machine, and there is a possibility that noise may occur due to nailing in an apartment house or a quiet residential area. (G) Health and fire hazards When the adhesive is used for fixing, it contains toluene and other organic solvents that are harmful to health and highly flammable. May volatilize, impairing the health of workers and causing a fire.

On the other hand, the heat-generating member-integrated type is one in which a heat-generating member is embedded in the floor material, and is usually fixed on the joists in sequence with nails or adhesives, and the heat-generating members between the floor materials are joined together. Are configured to be connected via a connector.
This heat-generating member integrated type has the convenience that construction can be performed only by laying a floor material and connecting the heat-generating members to each other.

However, this heat generating member integrated type is
It has the following drawbacks. That is, (a) Since it is necessary to connect the heat-generating members to each other through the connectors for each floor material that has a large number of connection points between the heat-generating members, the connection requires a great deal of labor and time and is based on a large number of connectors. Frequent problems such as poor contact. (B) Exchange of floor material is difficult or impossible It is expensive because the floor material and the heat generating member are integrated, and it is impossible to exchange only the floor material. Furthermore, since the floor material is fixed with nails or adhesives, it takes a lot of labor and time to remove it. Moreover, complete removal is difficult. At that time, the floor material and heat generating panel are damaged by the nails (bars) and scraper blades, and reuse and reuse are impossible. Also, the waste material is dangerous because the nails are exposed. In addition, some of the floor materials have a decorative material portion fixed by screws and can be detached, but are more expensive, and the dowels for closing the screws are exposed, so that the appearance is not good. (C) Difficult to partially change the heating area after installation Due to the reason (b) above, it is extremely difficult to partially change the heating area after installation. Therefore, when it is expected that the heating area will be partially changed by changing the floor plan such as movement of furniture, it is desirable to lay a floor material in which a heating member is buried up to a portion where heating is not required for the time being.

In addition, there are the same problems as (d) to (h) of the heat generating member separation type.

[0008]

Therefore, an object of the present invention is to solve the problems of the conventional combination of the floor material for floor heating and the heat generating member, and to prevent the heat generating member from being damaged during construction. , It is easy to replace / reuse any floor material and heat generating member, and it is easy to change the heating area after installation.

FIG. 1 is a cross-sectional view showing an embodiment of the present invention, FIG. 2 is an exploded cross-sectional view of FIG. 1, and FIG. 3 is a perspective view showing a state before a heating member is held by a latch.

As shown in FIGS. 1 to 3, the floor heating floor structure according to the embodiment of the present invention is added to a structure constructed by combining a floor material 10 and a heat generating member 20. It is configured that the heating member 20 is easily retained by the lower surface of the flooring material 10 while being easily retained by the retaining member 30. A concave portion 12 is formed on the lower surface of the floor material 10 so that a heat generating material holding portion 33 described later can be stored therein. As a result, the combined thickness of the floor material 10 and the latch 30 becomes substantially equal to the thickness of the floor material,
The degree of freedom of installation is increased and the installation becomes easier. The heat generating member 20 is not particularly limited as long as it has a similar heat generating function such as an electric heating material and a hot water pipe and is long in one direction.

The latch 30 will be described in detail. The latch 30 is made of metal, plastic, or the like, and is formed at the center of the upper surface of the horizontal substrate 31 with a pair of elastic projections 32 that can be opened and closed elastically left and right integrally with the horizontal substrate 31. 32 is provided so as to project, thereby forming a heat generating material holding portion 33 in which the heat generating member 20 can be easily fitted in and removed from the space surrounded by the pair of convex strips 32, 32 and the horizontal substrate 31. It As the heat generating material holding portion 33, one that can hold two heat generating members 20 for reciprocating, and one that can hold one heat generating member 20 with only one way as shown in FIGS. 4 to 6. However, the number that can be held is not particularly limited.

Further, on the upper surface of the horizontal base plate 31, hooking portions 35, 35 each having an enlarged head at the tip end are projected, and are formed on the lower surfaces of the two adjacent floor boards 10, 10. Further, it is configured to be hooked on at least a pair of concave receiving members 11, 11 having a C-shaped cross section that can be opened and closed elastically to the left and right. The hooking portions 35, 35 are the ridges 32, 32.
It is formed in a straight line parallel to, and makes it easy to hook the concave receivers 11, 11 to the hook portions 35, 35. As the hooking portions 35, 35, at least one pair of concave receivers formed on the lower surface of one floor material may be hooked (not shown).

In the construction, first, the respective hooks 30 are installed in parallel on the upper surface of a base material such as plywood or concrete at appropriate intervals. Next, the heat generating member 20 is fitted into the heat generating material holding portion 33 of each of the hooks 30. Further, the corresponding recessed receiving members 11, 11 of the flooring 10 are fitted to the hooking portions 35, 35 of the respective hooking members 30 and hooked. The construction is complete. As mentioned above, basically, nails and adhesives are not used for fixing.

In addition, a cushioning material 40 (including a sound insulating material) such as urethane foam or felt is integrally bonded to the lower surface of the floor material 10 and the lower surface of the latch 30 to reduce floor impact sound or sound insulation. What has been done may be used. Further, an aluminum sheet for heat diffusion, a buffer plate, a sound insulating plate, etc. may be inserted between the floor material 10 and the hook 30 (not shown).

To explain the operation, since nails are not used in fixing the flooring 10, the position of nailing
The heat generation member 20 is not damaged due to an erroneous direction, and therefore, electric leakage, water leakage, and other troubles do not occur.

Also, there is no noise caused by nailing during construction,
It does not disturb others. Moreover, since no adhesive is used, both the floor material 10 and the heat generating member 20 can be easily attached and detached, and can be stored and reused without being damaged by removal and replacement. Therefore, it is easy to change the heating area (removal, position change, expansion, etc.) accompanying the change of furniture after installation, etc., and no extra work such as installing the heat generating member 20 in an unnecessary area in advance is required. Is. In addition, even if the heating area is partially changed, the floor material 10 does not change at all, the appearance does not change before and after the change, and the floor material 10 is indistinguishable.

Further, since the adhesive is not used, there is no danger to the health and fire of the worker due to volatilization of the solvent. Floor material 1 because it is not fixed by nails or adhesive
Since 0 easily follows expansion and contraction due to changes in temperature and moisture, the gap hardly changes and squeaking is rare. In addition, even if there is a possibility of stomping,
It can be easily modified. The heat generating member 20 need only be fitted in advance to the heat generating material holding portion 33, and the number of man-hours for connecting a connector or the like is small, so that troubles such as contact failure due to it are small.
