Definitions
- the present invention relates to a floor heating radiator and a floor structure capable of heating using the radiator.
- Such a floor heating structure generally includes a base material layer in which a heating pipe through which a heat medium passes is provided on a base material, and a heat transfer layer such as a metal foil is disposed above the base material layer.
- the most basic one is one in which a surface covering material is arranged on the upper surface of the device.
- Various improvements of such a structure are known.
- Japanese Patent Application Laid-Open No. 2002-81662 discloses that a synthetic resin sheet layer is provided on a metal foil of the floor heating radiator. Proposed. With this structure, the floor heating radiator can be prevented from being damaged, and the work of replacing the facing material can be easily performed.
- flooring materials for buildings have also been diversified, and hardwood, stone slabs, thin wooden flooring materials, soundproofing flooring materials for direct assembly, flexible cars, cushion floors, etc.
- a surface covering material is exemplified.
- a floor heating radiator that can sufficiently meet the requirements of strength, elasticity, heat transfer, and the like that can cope with any of these is desired.
- FIG. 1 is a vertical sectional view of an example of a floor heating radiator according to the present invention. Disclosure of the invention
- the present inventors have been studying structural improvement of floor heating for many years, but recently, the above-mentioned composite material of metal and resin, which has been used exclusively as an exterior building material, has been used for floor heating. When applied to the structure, they found that very good results were achieved, and arrived at the present invention.
- the present invention provides a floor heating and heat radiation system, wherein a composite plate in which metal plates are bonded to both surfaces of a resin sheet core material is disposed above a base material layer in which a heating pipe through which a heat medium passes is embedded.
- a composite plate in which metal plates are bonded to both surfaces of a resin sheet core material is disposed above a base material layer in which a heating pipe through which a heat medium passes is embedded.
- Examples of the heat medium to be passed through the heating pipe include hot water, steam, and heated oil, and preferably hot water.
- a flexible tube is usually used for the heating pipe, and examples thereof include a crosslinked polyethylene pipe, a polybutene pipe, and a copper pipe.
- the diameter can be changed depending on the area where the building is built, the location of the building where the floor heating panel is installed, the type of heating medium, the temperature, etc., but the outer diameter is 6 to 10 mm, Inner diameter: ⁇ 6 mm tubing is common.
- a sound insulating material layer such as a nonwoven fabric may be provided below the base material layer.
- a groove for embedding a heating pipe is formed on the surface of the plate-like body constituting the base material layer, and the heating pipe is embedded in this groove.
- the width of the opening of the groove is preferably the same as or slightly larger than the outer diameter of the heating pipe.
- the shape of the groove is such that the cross section cut at a right angle to the extending direction forms a U-shape, it is convenient when the heating pipe is buried.
- the depth of the groove is the same as the outside diameter of the heating pipe.
- the depth of the groove is larger than the outer diameter of the heating pipe, a gap is created above the heating pipe when the heating pipe is buried, and the heat of the heat medium cannot be transferred effectively to the surface material. It is not preferable because the heat transfer efficiency of the floor heating panel decreases.
- the metal plate for example, a sheet made of a metal such as aluminum, stainless steel, iron, copper, titanium, tin, nickel, or various alloys is used, but from the viewpoint of workability, heat transfer, rigidity, etc., an aluminum plate is used. Is preferred.
- the method for producing the composite plate is not particularly limited, but usually, a method of extruding a resin raw material to obtain a core material sheet, and then joining a metal sheet to both surfaces of the core material sheet via an adhesive film is used. Adopted.
- a thermoplastic resin film having affinity for both the core material sheet and the metal sheet is used.
- the thermoplastic resin include ethylene-acrylic acid copolymer, ethylene-vinyl acetate copolymer, ethylene-daricidyl acrylate copolymer, ethylene-maleic anhydride copolymer, and polyethylene. And a maleic anhydride graft copolymer of polyethylene.
- the thickness of the above composite board is usually about 0.5 to 6.0 mm, preferably about 0.7 to 5.0 mm.
- the rigidity can be increased without sacrificing its lightness.
- the resin sheet is too thick, the electrical conductivity as floor heating may be impaired.
- a bending elastic modulus of the composite plate is usually 1000 to 10000 kg / mm 2 , preferably within a range in which a pleasant foot feeling can be expected.
- 3000-8 is 0 0 0 Kg / mm 2.
- the thickness of the resin sheet is 0.5 to 3.0 mm
- the thickness of the metal plate is 0.05 to 1.0 mm.
- the metal plate is usually made of substantially the same material on both sides and has the same thickness. This minimizes the warpage of the composite board during floor heating.
- the composite board and the base layer are usually fixed via an adhesive layer.
- the adhesive strength between the composite plate and the base material layer is usually 6 NZ 2 Omm or more at 60 ° C., preferably 8 NZ 20 mm or more, mainly for preventing peeling of both layers.
- noise may occur when walking on the floor equipped with a floor heating radiator, and from the viewpoint of completely preventing this, the viscosity of the adhesive used for the adhesive layer at 5 ° C must be reduced.
- the thickness of the pressure-sensitive adhesive layer is set to 1200 exp (0.02 x) Pa's or less as x / xm.
- the pressure-sensitive adhesive used as the pressure-sensitive adhesive layer is not particularly limited as long as it satisfies the above conditions. Usually, acrylic-, vinyl-ester-, natural-rubber-, and synthetic-rubber-based pressure-sensitive adhesives are used. Acrylic pressure-sensitive adhesive excellent in heat resistance and heat resistance is preferred.
- Such an adhesive may be applied and adhered to at least one of the base material layer and the composite board, but since it requires time and labor for construction, a sheet of paper or resin having a thickness of usually 5 to 250 xm is required. It is preferable to form a pressure-sensitive adhesive layer by sandwiching a layer of a pressure-sensitive adhesive, which is usually applied in equal amounts on both sides, between the composite plate and the base material layer and bonding them.
- the thickness of the adhesive layer is ideally preferably thinner, usually 300 zm or less, preferably 200 m or less. If the thickness is further increased, the adhesiveness is improved and the problem of sound noise tends to be reduced, but it is not rational due to the necessity of an excessive adhesive material.
- the lower limit of the thickness is not particularly limited.
- the thickness of the pressure-sensitive adhesive layer in the case where the pressure-sensitive adhesive is applied to both sides of the sheet means the thickness excluding the thickness of the sheet.
- the adhesive used for the adhesive layer must have a viscosity within the above range. According to the study results of the present inventors, it is considered that the sound generated by the floor heating radiator having the layer configuration as in the present invention is caused by peeling at the interface between the base material layer and the adhesive material layer. After peeling, the adhesive layer will be peeled off at the interface. It is presumed that the sticking occurs again when the load is released, and when the load is released, it peels off at the interface and makes a sound. And, as the adhesive material has a higher adhesive strength and a lower viscosity, it is possible to prevent noise even if the adhesive layer is made thinner. In general, the higher the viscosity of the adhesive, the higher the adhesiveness can be expected. However, the adhesive layer is too hard, so that sound is more likely to be generated. On the other hand, if the viscosity of the adhesive is too low, it is not preferable because the adhesive strength becomes insufficient.
- the viscosity of the adhesive at 5 ° C and the thickness of the adhesive layer are x_im. And 1 2 0 0 exp (0. 0 2 X) P a 's or less.
- the relational expression here shows a boundary line derived from a large number of experimental measurement values.
- the adhesive strength between the composite board and the adhesive layer is usually smaller than the adhesive strength between the substrate and the adhesive layer, and the problem of peeling and noise can be determined to occur mainly between the substrate and the adhesive layer. .
- a sheet having a thickness of 0.1 to 2 mm is symmetrically joined to both sides of the plywood, and a surface covering material of 1 to 6 mm thickness is preferred. Suitable. Although this range of thickness is thinner than that of the conventional surface finishing layer, the structure, in which thin sheets of approximately the same quality and thickness are joined symmetrically on both sides of the plywood, has been considered as a problem in the past. Warpage of the finish is avoided. That is, by using the same material for the upper surface and the lower surface of the core material, the difference in expansion and contraction generated between the upper surface and the lower surface of the core material is reduced, and it is possible to effectively prevent warpage.
- the composite plate may be too strong to be damaged due to its strength as a surface material and may be insufficient.
- the surface covering material may be easily warped.
- the standard of the allowable warpage of the surface material having the thickness in the above range is usually 0.4 mm or less per 100 mm in the longitudinal direction, and 1.0 mm or less per 100 mm in the width direction. Is 2 mm or less per 100 mm in the longitudinal direction and 0.5 mm or less per 100 mm in the width direction.
- Such surface covering materials can be widely used regardless of the structure and type of the floor heating radiator in which they are installed.
- the plywood used for the facing material constituting the above-mentioned facing material may be selected from those having a desired thickness from those used for building materials.
- a sheet made of a film or paper having a thickness of usually 100 to 200 m is used, and the sheet is brought into close contact with the plywood via an ordinary adhesive. Further, the surface of such a sheet may be provided with a pattern such as wood grain from the viewpoint of design.
- the floor slab where the floor heating radiator is to be installed is on the slab floor for concrete buildings, on the base plywood laid on the slab floor, etc. It is. It can also be installed on an existing floor with flooring.
- the floor insulation panel That is, a panel laid on the floor between the peripheral portion of the floor heating mat laid on the floor of the room and the inner wall surface of the room and / or the portion where the floor heating mat is not laid. Further, the floor heat insulating panel is characterized in that the panel is made of a resin foam, and has a large number of shallow groove pitches substantially evenly on the back surface of the panel and deep groove pitches at regular intervals.
- This floor insulation panel is made of a resin foam, and is characterized by having a large number of shallow groove pitches substantially uniformly on the back surface of the panel and a deep groove pitch at regular intervals.
- the shallow groove pitch is usually a groove shape having a depth of l to 4 mm and an opening width of 1 to 5 mm, and is almost uniformly provided at intervals of 1 to 30 mm. Further, the outer periphery of the opening may have a slightly convex shape. If the groove depth exceeds 4 mm, the amount of adhesive applied tends to increase, which is not preferable.
- the groove-shaped concave portion may be cut at a right angle to a direction in which the groove extends, and the cut surface may be semicircular, U-shaped, V-shaped, U-shaped, or the like. It is not done.
- the panel is laid on the floor by applying an adhesive to the back surface having a pitch.
- the height of the floor insulation panel may be generally adjusted to the height of the base panel of the floor heating mat.
- a heat transfer layer provided on the base layer of the floor heating mat and the same layer as the surface finishing material may be provided on the panel.
