Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor heating structure and a construction method thereof, and more particularly to a floor heating structure and a construction method thereof that can simplify a construction process.
[0002]
[Prior art]
There is known a floor heating structure in which a linear heating element such as a hot water pipe or an electric heater is disposed on a floor substrate to warm the entire floor surface. Construction methods are as follows: (1) A method of arranging a large number of heating floors with heating elements integrated in advance on the back side of a surface material such as a wood floor material on the floor substrate, (2) Thermal insulation A method of arranging a floor surface material on a floor substrate having a structure in which a heating element is accommodated in a groove formed on the material using a small joist, etc. (3) A method in which a floor surface material in which a through hole for inserting a heating element is formed on the back surface is first disposed on a floor substrate, and then a heating element is disposed through the through hole (for example, JP-A-9-105532, JP-A-10-253085, etc.) are known.
[0003]
In the method (1), it is necessary to connect heating elements (for example, hot water pipes) to each other by using a joint or the like for each adjacent heating floor material, and a long time is required for connection work. Method (2) is the work of placing the floor substrate on the floor substrate, placing the heating element in the groove formed in the placed floor substrate, and placing the floor surface material thereon. , And requires a lot of work, and construction takes time. Moreover, the operation | work which adjusts foundation | substrate height between the surrounding parts which do not construct floor heating is also needed. Method (3) is a relatively labor-saving method for floor heating construction, but it is a careful work to insert a heating element through the through hole in the floor surface material placed on the floor substrate. Is required.
[0004]
As another construction method, as shown in FIG. 4, a base sheet 3 is laid on the entire surface of the floor substrate 1 on which the discarded plywood 2 is pasted, and a heating element accommodating duct 4 is fixed thereon at a predetermined interval. The floor surface material 20 formed with a housing recess 21 that opens downward on the lower surface corresponding to the position of the heating element housing duct 4 is attached thereto. There has been proposed a structure in which the heating element accommodating duct 4 is accommodated in the accommodating recess 21 and is fixed on the base sheet 3 (see Japanese Patent Application Laid-Open No. 7-167448).
[0005]
[Problems to be solved by the invention]
The construction method shown in FIG. 4 is an aspect in which the back surface of the floor surface material 20 is fixed in direct contact with the upper surface of the base sheet 3, and the height of the ground is set between the part where the floor heating is not performed. Adjustment work is unnecessary, and a certain amount of labor can be saved. However, an operation of laying the base sheet 3 on the entire surface of the floor substrate 1, an operation of fixing the heating element accommodating duct 4 (and the heating element 2) with a fixing tool 7 at a predetermined interval, and further, The floor surface material 3 is fixed and the work basically requires three operations. Further, in order to lay the base sheet 3 on the entire surface of the floor substrate 1, an adhesive is applied to the surface of the floor substrate 1. The operation | work which apply | coats and the operation | work which has arrange | positioned the base material sheet 3 from the top are required. And all of these are operations performed at the construction site, and require a long on-site construction time.
[0006]
The present invention has been made in view of the above circumstances, and the various functions performed by the floor heating structure after construction are the same as the conventional ones, but the work process at the construction site is reduced and the floor is constructed in a short time. An object of the present invention is to provide an improved floor heating structure capable of finishing the heating construction and a construction method thereof.
[0007]
[Means for Solving the Problems]
In the floor heating structure according to the present invention for solving the above-described problem, a sheet with a heating element in which a heating element is previously fixed on a base sheet is laid on the upper surface of a floor substrate, and the heat generation is performed on the back surface thereof. The floor surface material with a storage part that forms a storage part of the body is a floor heating structure in which the heating element is stored in the storage part, wherein the base sheet transmits or penetrates the adhesive The base sheet and the floor surface material are capable of being integrally bonded and fixed together with the floor substrate by an adhesive disposed in a portion other than the storage portion on the back surface of the floor surface material. To do.
[0008]
The base sheet is formed of a material that allows the adhesive to permeate from the front surface to the back surface, such as a non-woven fabric, or is adhesive-impermeable such as kraft paper, resin-impregnated paper, and polyolefin-based sheets. It may be made of a material, and a hole is formed there, and the adhesive can reach the back surface from the front surface through the hole. You may make it form a hole further with respect to the material which an adhesive agent can permeate | transmit. In the case where a heat-insulating sheet such as a nonwoven fabric is used as the base sheet, the heat-insulating property of the floor heating structure can be improved at the same time.
[0009]
In the floor heating structure according to the present invention, a sheet with a heating element in which a heating element is fixed on a base sheet in advance is made at a place other than a construction site, for example, a factory, and is carried into a floor heating construction site. At the construction site, simply laying the sheet with the heating element on the floor board surface, both the laying of the base sheet and the arrangement of the heating element can be completed at the same time, saving labor in the field construction. It is done.
[0010]
Furthermore, the sheet with the heating element and the floor surface material are structures that are integrally bonded and fixed together with the floor substrate by an adhesive disposed on the back surface of the floor surface material other than the storage portion, as in the past. In addition, the operation of applying the adhesive to the floor substrate can be omitted. Thereby, labor saving of field work is also achieved here. In addition, fixing a heat generating body to a base material sheet in a factory or the like can be easily performed using, for example, a hot melt adhesive or by heat fusion.
[0011]
In a preferred embodiment, the protective cover is attached to the base sheet with a hot melt adhesive or the like so as to cover the heating element. In this aspect, due to the presence of the protective cover, the adhesive to be used can be prevented from inadvertently adhering to the heating element, and when an adhesive that damages the heating element in relation to the material is used. Even if there is, it is possible to quickly perform on-site construction such as adhesive application without worrying about the occurrence of such damage. Although there is no restriction | limiting in particular in the raw material of the said protective cover, The embossed article by a kraft paper, the extrusion molded article of ABS resin, etc. are suitable for reasons of easiness of a process and required heat resistance.
[0012]
The floor surface material can be appropriately used what has been used in conventional floor heating, and there is no particular limitation, but aluminum foil as a soaking material was kneaded between the upper layer decorative plywood and the lower layer plywood. Such a wood floor material is preferred. A material that is actually machined around is particularly preferable from the viewpoint of quickness and certainty of construction.
[0013]
The present invention further provides, as a method for constructing the above-mentioned floor heating structure, the above-described sheet with a heating element is disposed on a floor substrate, and the floor surface material having the above-described configuration is arranged on the back surface of the floor surface material. Either press-contact from above the base sheet in a state where the adhesive is applied to a portion other than the storage section, or apply the adhesive to the region between the heating element and the heating element in the disposed base sheet, From above, the floor surface material having the above-described configuration is pressed into the housing portion so that the heating element is housed, and thereby the adhesive is cured in a state where it penetrates or penetrates the base material sheet. The construction method of the floor heating structure characterized by integrally bonding and fixing a material sheet, a floor surface material, and a floor substrate is also disclosed. According to this construction method, the various functions performed by the floor heating structure after construction are the same as the conventional one, but the floor heating construction can be completed in a short time with fewer work processes at the floor heating construction site. It becomes possible.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, some preferred embodiments of a floor heating structure and its construction method according to the present invention will be described with reference to the drawings. In the sheet shown in FIG. 1, the heating element-attached sheet 35 uses a heat-insulating sheet such as a non-woven fabric as the base material sheet 30, and generates heat on a non-woven fabric having a required area, preferably having a rough basis weight. The body 10 (for example, a hot water pipe which is a crosslinked polyethylene pipe) is fixed in parallel with a hot melt adhesive at a predetermined interval. The heating element-equipped sheet 35 is manufactured at a place other than the floor heating construction site, such as a factory, and is carried into the construction site.
[0015]
At the construction site, the sheet 35 with the heating element carried in is applied as it is, that is, on the floor substrate 1 similar to the conventional example, for example, on the floor substrate 1 to which the discarded plywood 2 is adhered. Laying without. If necessary, it may be laid after partial application. After that, the floor surface material 20 is placed together with the adhesive 40 on the sheet 35 with the heating element. As the floor surface material 20, one that has been used in conventional floor heating can be used as appropriate, but in this example, as a soaking material between the upper plywood 25 and the lower plywood 26. A wooden floor material in which aluminum foil 27 is kneaded is used. On the back surface of the floor surface material 20, a storage portion 21 that can store the heating element 10 fixed on the heating element-equipped sheet 35 is formed.
[0016]
The adhesive 40 may be applied in a line shape or a dot shape to a portion other than the storage portion 21 on the back surface of the floor surface material 20, and the heating element 10 and the heating element 10 in the base sheet 30 arranged. Similarly, it may be applied in the form of a line or a dot in the area between. You may make it apply | coat to both (FIG. 1 a). Thereafter, while the adhesive 40 is uncured, the required number of floor surface materials 20 are pressed from above so that the heating element 10 is stored in the storage portion 21. Thereby, the adhesive agent 40 permeate | transmits the base material sheet | seat 30 with a coarse mesh, and reaches | attains the surface of the floor substrate 1 (FIG. 1b).
[0017]
It waits for the adhesive 40 to harden in that state. At that time, if necessary, an appropriate load is placed on the floor surface material. By curing the adhesive, the base sheet 30, the floor surface material 20, and the floor substrate 1 are integrally bonded and fixed, and the same conventional floor heating structure is completed.
[0018]
The embodiment shown in FIG. 2 is different from that shown in FIG. 1 in the configuration of the base sheet 30 constituting the sheet 35 with the heating element. Here, the base material sheet 30 is made of a material that does not transmit an adhesive such as kraft paper. And in the area | region between the heat generating body 10 and the heat generating body 10 in the base material sheet 30, many holes 31 are formed along the longitudinal direction of the heat generating body 10. FIG. The other structure is the same as that of FIG. 1, and the application mode of the adhesive is also the same. Also in this form, the adhesive 40 can reach the surface of the floor substrate 1 through the hole 31, and as a result, the base material sheet can be cured by curing the adhesive, similar to that shown in FIG. 1. 30, the floor surface material 20, and the floor substrate 1 are integrally bonded and fixed. Although not shown, the holes 31 may be formed in the same manner on a base material sheet having adhesive permeability such as a nonwoven fabric.
[0019]
FIG. 3 shows still another embodiment. Here, the protective cover 32 is further attached to the base material sheet 30 so as to cover the heating element 10 fixed on the base material sheet 30. The protective cover 32 is preferably made of a material that has the required heat resistance, is impermeable to the adhesive 40 used during construction, and does not cause a chemical change. Such materials are used. The cross-sectional shape may be any shape that can cover the heating element 10 from the outside. For example, the cross-sectional shape is made by embossing kraft paper so as to form the illustrated rectangular cross-section or semicircular shape. It may be an extruded product of a resin material such as ABS resin. The attachment of the protective cover 32 to the base material sheet 30 may be performed at the same time when the heating element 10 is fixed to the base material sheet 30 in a factory, or may be performed at a construction site as necessary. The attachment can be performed using a hot melt adhesive or the like.
[0020]
By using such a protective cover 32, it is possible to easily avoid the adhesive 40 used from adhering to the heating element 10. Therefore, even when an adhesive that damages the heating element 10 in relation to the material is used, there is an advantage that it is possible to perform on-site construction quickly. In FIG. 3, the protective cover 32 is attached to the base sheet 30 having the holes 31, but the heating element-attached sheet using the base sheet 30 made of a non-woven fabric without holes as shown in FIG. 1. Similarly, the protective cover 32 is used for 35.

【The invention's effect】
As described above, in the floor heating structure and its construction method according to the present invention, a sheet with a heating element in which a heating element is fixed in advance on a base sheet is made at a place other than the construction site, for example, a factory, At the construction site, both the laying of the base sheet and the arrangement of the heating elements can be completed at the same time by simply spreading the sheet with the heating elements on the floor substrate surface. As a result, work on site construction is greatly labor-saving.
[0022]
Furthermore, since the sheet with the heating element and the floor surface material are integrally bonded and fixed to the floor substrate at the same time by an adhesive partially applied to the base sheet or the floor surface material, The work of applying the adhesive to the entire surface of the floor substrate can be omitted, and the labor saving of the field work is also achieved here. From these things, while the various functions which the floor heating structure after construction plays are the same as the conventional one, the time required for floor heating construction is greatly shortened, and the construction cost is greatly reduced.
