Description

  The present invention relates to a method for constructing a floor heating apparatus in which, for example, a heat generating sheet member is laid on a floor base surface, and more particularly to a method for constructing a floor heating apparatus in which the heat generating sheet member is attached with a tape.

  Conventionally, when laying a floor heating device, it is necessary to cure for a certain period after applying and applying an adhesive to each member. Therefore, work and placement of objects on the floor cannot be performed during the curing period, resulting in loss of time and money for the contractor and residents.

  Therefore, a construction method using an adhesive double-sided tape instead of an adhesive has been adopted. That is, it is a construction method in which the heat generating sheet member and the surface finish material are attached with an adhesive double-sided tape. This method has the advantages that it does not require curing time, has no odor, and can be placed on the floor and placed immediately after being attached.

  However, when the pitch is adjusted to a general floor finish pitch width, a certain gap is formed between adjacent heat generating sheet members, so that the surface finish material is projected. That is, smooth unevenness is formed on the surface finishing material at the level difference from the floor base surface made of the thickness of the heat generating sheet member. In addition, since the adhesive flowed and buried in the gap between the heat generating sheet members when projected with an adhesive, no projection occurred.

  Then, the idea which eliminates the level | step difference which arises between a heat generating sheet member and a floor base surface with a spacer member is proposed (for example, refer patent document 1). As the spacer member, an adhesive tape such as a gum tape may be used, and the spacer member may be overlapped a plurality of times.

  However, the above-described conventional construction method describes that an adhesive tape is used to temporarily fix the heat generating sheet member to the floor base surface. That is, in this construction method, the heat generating sheet member and the surface finishing material are pasted with an adhesive, and there is no idea of pasting with a pressure-sensitive adhesive tape, and it does not solve the problem related to reduction or shortening of the curing period.

  In housing complexes, demand for introduction of floor heating devices is increasing. For this reason, after the introduction, replacement work occurs at any time according to the life or breakage of the heat generating sheet member. However, since the construction method of the prior art uses an adhesive, it cannot be replaced unless the surface finish or the heat generating sheet member is destroyed. Therefore, the cost of reforming increases.

  Further, in order to keep the indoor temperature constant in winter, the floor heater is often operated at all times. However, if there is a gap between the heat generating sheet members, it is difficult for heat to be transmitted to the surface finishing material, which not only increases the electricity bill in the home, but also causes global warming.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a construction method that shortens the construction time of a floor heating apparatus and does not use unnecessary materials and is low in cost and labor. Another object of the present invention is to improve the efficiency of reforming a floor heating device. Furthermore, another object of the present invention is to improve the electric heating efficiency of the floor heating device.

  In order to solve the above-mentioned problems, the construction method of the floor heating apparatus according to the present invention is characterized in that a floor base surface or a surface finish material and a heat generating sheet member are adhered to each other between adjacent heat generating sheet members with an adhesive double-sided tape. It is to fill a certain gap that can be made and eliminate the step between the floor base surface and the heat generating sheet member.

  That is, the floor heating apparatus construction method according to the present invention is a floor in which a heat generating sheet member is installed on a floor base surface with a certain gap, and a surface finishing material is laid on the heat generating sheet member via an adhesive double-sided tape. In the construction method of the heating apparatus, the adhesive double-sided tape is narrower than the gap, and the adhesive double-sided tape is attached to the floor base surface of the gap, and the adhesive double-sided tape is further applied to the adhesive double-sided tape. It is characterized by that. With this configuration, the adhesive double-sided tape originally prepared for attaching the heat generating sheet member can be diverted, and the adhesive double-sided tape fills the gap between the adjacent heat generating sheet members, so that the step between the floor base surface and the heat generating sheet member can be easily made. Can be resolved.

  Further, if the adhesive double-sided tape is excessively stacked, it may protrude from the upper surface of the heat generating sheet member, which may cause a new step. Therefore, it is desirable that the upper surface of the adhesive double-sided tape that is overlapped and pasted does not exceed the upper surface of the adjacent heat generating sheet member. With this configuration, it is possible to prevent the occurrence of a new step formed by the double-sided adhesive double-sided tape.

  Moreover, since the adhesive double-sided tape in which the gap between the heat generating sheet members is filled does not have a heat generating function, it is difficult for heat to be transmitted to the surface finishing material located on the upper side of the adhesive double-sided tape. Therefore, it is desirable to cover the upper surface of the double-sided adhesive double-sided tape and the top surface of the heat generating sheet member adjacent to the double-sided adhesive tape with metal foil. With this configuration, the heat of the heat generating sheet member is transmitted to the metal foil, and the heat generating sheet member located above the adhesive double-sided tape is also easily warmed.

  According to the present invention, the use of the adhesive double-sided tape eliminates the curing period and shortens the construction time of the floor heating device, and uses the floor base surface and the heat generating sheet member without using unnecessary materials and at low cost. It is possible to provide a construction method that eliminates the level difference and prevents the projection of the surface finish. In addition, since the adhesive double-sided tape is easy to apply and remove, it is possible to improve the efficiency of reforming the floor heating device. Furthermore, the use of a metal foil covering the adhesive double-sided tape with the gap filled in is to improve the electric heating efficiency of the floor heating device.

  As shown in FIG.1 and FIG.2, the floor heating apparatus 1 installs the heat generating sheet members 12 and 12 on the floor base surface 11 with a certain gap K, and has an adhesive double-sided tape 13b on the heat generating sheet member. The surface finishing material 14 is laid. The width of the adhesive double-sided tape 13b is narrower than the gap K, and the same adhesive double-sided tape 13a as the adhesive double-sided tape 13b is attached to the floor base surface of this gap, and the adhesive double-sided tape 13a is further laminated on the adhesive double-sided tape. In addition, the upper surface of the upper adhesive double-sided adhesive tape 13a that is overlapped is prevented from exceeding the upper surfaces of the adjacent left and right heat generating sheet members 12 and 12. Furthermore, at least the edge part of the upper surface of the upper adhesive double-sided tape 13a and the heat generating sheet members 12 and 12 adjacent to the adhesive double-sided adhesive tape is covered with a metal foil 15.

  For example, a base material such as slab, plywood, “Zetron” (registered trademark) manufactured by Sekisui Chemical Co., Ltd. may be provided on the floor base surface 11 and there is no particular limitation as long as it is a general structure as an apartment house.

  The heat generating sheet member 12 is composed of a base material made of, for example, a polyester film, a planar heat generating element composed of a metal foil, and an electrode, and has a predetermined thickness and area, and has a general structure and dimensions. If there is no particular limitation. The planar heating element is, for example, a nichrome wire flattened or a patterned metal plate that generates heat, and it uses PCT characteristics that make it difficult for electricity to flow when the temperature rises and easily flows when the temperature drops. May be.

  The adhesive double-sided tapes 13a and 13b are the same. The base material of the adhesive double-sided tapes 13a and 13b is preferably, for example, a polyolefin film, a cellophane film, an acrylic film, a polyvinyl chloride film, a polyester film, a cloth, a non-woven fabric, paper, or a polyolefin foam that does not easily deteriorate over time. The pressure-sensitive adhesive for the pressure-sensitive adhesive double-sided tapes 13a and 13b is preferably, for example, a rubber-based, acrylic-based, or synthetic-resin-based one that has an adhesive force and is easily separated when removed. The widths of the adhesive double-sided tapes 13a and 13b are preferably narrower than the gap between adjacent heat generating sheet members.

  The surface finish 14 is made of, for example, plywood, particle board, wood material such as high density fiber (HDF) or medium density fiber (MDF), thermoplastic resin such as polyethylene or polypropylene, and thermosetting resin such as polyester or epoxy resin. The material is not particularly limited as long as the material does not cause breakage or damage to a general load. The surface finish may be provided with, for example, a decorative synthetic resin sheet, a veneer, decorative paper, or a surface decorative material.

  The metal foil 15 is, for example, an aluminum foil or an aluminum tape coated with an adhesive on the back surface, and preferably has a thickness that does not cause projection (unevenness) when the surface finish is laid from above. The width of the metal foil 15 is preferably wider than the gap width between adjacent heat generating sheet members.

  Next, the construction method of the floor heating apparatus having such a configuration will be described with reference to FIG.

  First, at a predetermined position on the floor base surface 1 (FIG. 3 (a)), the heat generating sheet members 12 are arranged in a plurality of rows with a certain gap K (FIG. 3 (b)). Therefore, a step is generated between the floor base surface 1 and the heat generating sheet member 12. Although the floor base surface 11 and the heat generating sheet member 12 may be attached with an adhesive double-sided tape, they are not shown.

  Next, the adhesive double-sided tape 13a is affixed to the floor base surface 1 of the gap K (FIG. 3C), and the adhesive double-sided tape 13a is further affixed thereon (FIG. 3D). At this time, it is preferable that the double-sided adhesive tapes 13a and 13a are applied to the floor base surface 1 of the gap K so as to overlap each other at a position where they do not contact the heat generating sheet member. Accordingly, the adhesive double-sided tape 13b originally prepared for attaching the heat generating sheet member 12 can be diverted, and the pressure-sensitive adhesive double-sided tape fills the gap between the adjacent heat generating sheet members. Can be eliminated. The number of double-sided adhesive double-sided tapes to be overlaid may be affixed and overlaid depending on the thickness of the double-sided adhesive tape.

  At this time, the upper surface of the uppermost adhesive double-sided tape 13a is laminated and pasted up to a height that does not exceed the upper surfaces of the adjacent heat generating sheet members 12,12. Thereby, generation | occurrence | production of the new level | step difference which can be performed with the adhesive double-sided tape which has pasted too much can be prevented.

  Further, at least the end portion adjacent to the adhesive double-sided tape 13a is covered with the metal foil 15 among the upper surfaces of the upper adhesive double-sided tape 13a and the heat generating sheet members 12 and 12 adjacent to the adhesive double-sided tape (FIG. 3E). ). As a result, the heat of the heat generating sheet members 12, 12 is transmitted to the metal foil 15, and the surface finish 14 located on the adhesive double-sided tape 13a is also easily warmed.

  Finally, an adhesive double-sided tape 13b is pasted so as to cross the plurality of heat generating sheet members 12 and the metal foil 15 (FIG. 3 (f)). A surface finish 14 is laid from above (FIG. 3 (g)).

  According to the construction method of such a floor heating device, the use of the adhesive double-sided tapes 13a and 13b reduces the construction time of the floor heating device by eliminating the curing period, and at the low cost without using wasteful materials. It is possible to eliminate the level difference between the floor base surface 1 and the heat generating sheet member 12 without applying, and to prevent the surface finishing material 14 from being projected. Moreover, since the adhesive double-sided tapes 13a and 13b can be easily attached and removed, it is possible to improve the efficiency of reforming the floor heating device 1. Further, the use of the metal foil 15 covering the adhesive double-sided tape 13a, 13a with the gap filled in is to improve the electric heating efficiency of the floor heating device 1.

Next, examples of the present invention will be described. The dimensions and construction methods of each member are as follows.
Heat generation sheet member: 270 mm wide, 0.6 mm thick, arbitrary length Adhesive double-sided tape: 30 mm wide, 0.3 mm thick, arbitrary length Aluminum tape: 100 mm wide, arbitrary length

  Heat generating sheet members are installed at a pitch of 303 mm with respect to the floor base surface. Therefore, a gap of 33 mm is formed between the adjacent heat generating sheet members, and a step of 0.6 mm corresponding to the thickness of the heat generating sheet member is generated. Here, two double-sided adhesive tapes are stuck in a 33 mm gap so as not to contact the adjacent heat generating sheet member. Furthermore, an aluminum tape is stuck so that the adhesive double-sided tape and the edge part of the adjacent heat-generating sheet member may be covered. A surface finishing material is laid from above using an adhesive double-sided tape.

  The construction method of the floor heating apparatus according to the present invention can be widely used not only in apartment houses but also in industries related to individual houses, corporate buildings, medical facilities, nursing care facilities, and the like.
