Description

[0001]
BACKGROUND OF THE INVENTION
The present invention particularly relates to a heat insulating unit used for heat insulating construction such as a floor, a wall, and a roof in a wooden building, and a heat insulating method using the heat insulating unit.
[0002]
[Prior art]
In recent years, from the viewpoints of improving comfortability and energy saving, there has been an increasing demand for high heat insulation in houses and the like, and plate-like heat insulating materials such as polystyrene foam plates have been installed under the floor as heat insulating materials. Such a plate-shaped heat insulating material is constructed between structural materials such as large draws and joists if it is a floor, for example.
[0003]
As a construction method for improving the efficiency of the construction between the structural members of the plate-shaped heat insulating material and eliminating the gap between the surface plate such as a flooring material and the plate-shaped heat insulating material to improve the heat insulating effect, for example, Patent Document 1 discloses a method in which a unit in which a plurality of plate-like heat insulating materials are connected by a hanging material is fixed to a structural material by a hanging material portion so that the surface plate and the plate-like heat insulating material are brought into close contact with each other with good workability. Yes.

Japanese Patent No. 2693503 gazette
[Problems to be solved by the invention]
In the construction of the plate-shaped heat insulating material between the structural members, for example, when the size between the joists or the large draw is smaller than a prescribed size (particularly, the joist processing), it is necessary to cut the plate-shaped heat insulating material.
[0006]
However, in the heat insulating material unit described in Patent Document 1, the hanging material is attached to the plate-like heat insulating material, and the hanging material is also cut along with the cutting of the plate-like heat insulating material. It was necessary to stop using a fixing bracket or the like prepared separately on the cut surface side. For this reason, for example, as shown in FIG. 7A, the suspension member 72 is partially bonded only to the central portion of the plate-like heat insulating material 71, or the suspension member 72 is attached to the plate-like heat insulating material 71 as shown in FIG. It is possible to cut the end of the plate insulation without cutting the suspension material, but the assembly of the insulation unit is complicated. It becomes.
[0007]
Moreover, in the heat insulating material unit described in Patent Document 1, in order to eliminate the gap between the floor material and the plate-like heat insulating material and improve the heat insulating effect, a material having stretchability is used as the hanging material. Since construction is performed in a stretched state, depending on the material used, the suspension material may grow over time due to creep strain, and the plate-shaped heat insulating material may hang down, resulting in a decrease in heat insulation performance.
[0008]
The present invention has been made in order to solve the above-described problems. An insulating material unit that can be efficiently attached between structural materials by a simple operation and can maintain desired heat insulating performance for a long period of time. An object of the present invention is to provide a heat insulation method using this heat insulating material unit.
[0009]
[Means for Solving the Problems]
The present invention relates to a heat insulating material unit in which a plurality of plate-like heat insulating materials are integrated by a suspension material that is movably passed through a notch formed in the plate-like heat insulating material.
[0010]
According to the heat insulating material unit of the present invention, a plurality of plate-like heat insulating materials can be disposed at a time, and the construction is made efficient. In addition, since the suspension material is not fixed to the plate-like heat insulating material and is movable, the interval between the adjacent plate heat insulating materials can be easily adjusted, and when attaching the plate-like heat insulating material between the structural materials, For example, it is possible to easily cope with structural materials with different widths such as pillars and studs, and even when it is necessary to cut the heat insulating material according to the interval between the structural materials, the suspension material should be cut. The heat insulating material can be cut without any problem, and the cut surface side can also be stopped with the suspension material.
[0011]
In the heat insulating material unit of the present invention, it is preferable that the cut portions are formed along the longitudinal direction from two locations on both side surfaces in the longitudinal direction of the plate-shaped heat insulating material. According to this form, the suspension material can be easily passed through the cut portion, and the two insulation members are connected to both sides in the longitudinal direction of the plate insulation material. Can be connected and supported.
[0012]
Moreover, it is also preferable that the cut | notch part is formed in at least 2 places over the width direction full length of a plate-shaped heat insulating material. According to this form, the suspension member can be moved very easily to adjust the interval between the plate-like heat insulating materials, and the plate-like heat insulating material can be stably supported.
[0013]
Further, the present invention is a heat insulation method using the heat insulating material unit of the present invention, wherein the plate-shaped heat insulating material is disposed between structural materials in a state where the suspension material is tensioned, and then the heat insulating material. The present invention relates to a heat insulating method characterized by constructing a surface plate on the surface side of a unit.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
The heat insulating unit of the present invention is usually a unit in which several to a dozen plate-like heat insulating materials are integrated by a suspension material, and more specifically, a cut formed at a predetermined position of the plate-like heat insulating material. It is integrated by passing the suspension material continuously through the nail. In particular, in the heat insulating material unit of the present invention, the hanging material is not stuck and fixed to the plate-like heat insulating material as in the heat insulating material unit described in Patent Document 1, but simply in the cut portion of the plate-like heat insulating material. It is integrated with the suspension material in a movable state.
[0015]
As the plate-like heat insulating material, an ordinary plate-like heat insulating material such as a synthetic resin foam, an insulation board, glass wool or rock wool formed into a plate shape is used. Among these, lightweight and excellent water resistance, heat insulation, and processability are preferable. For example, a synthetic resin foam having closed cells such as a polystyrene resin foam, a polyethylene resin foam, and a polyurethane foam is preferable. In particular, extruded polystyrene (trade name “Styrofoam” manufactured by Dow Chemical Co., Ltd.) is most preferred because of its high heat insulation and low water absorption.
[0016]
As the suspension material, a synthetic resin film or a sheet-like material is used, but the sheet-like material may be paper, nonwoven fabric, knitted fabric, or woven fabric. Although there is no restriction | limiting in particular in the width | variety of this hanging material, The thing of about 50 mm-200 mm is suitable considering intensity | strength and workability.
[0017]
In the present invention, the suspension member is attached in a movable state without being attached to the plate-like heat insulating material, and the interval between the plate-like heat insulating materials can be easily adjusted. Stretchability like a material is not required. For this reason, the problem with the strength with respect to the long-term tensile creep of the suspension material, that is, the problem that the suspension material extends over time and the plate-like insulation material hangs down and the heat insulation performance deteriorates can be solved.
[0018]
Although various forms are possible for the notch part formed in a plate-shaped heat insulating material in this invention, the following two forms are mentioned as the typical example.
(1) The plate-like heat insulating material is formed along the longitudinal direction from two places on both side surfaces in the longitudinal direction.
(2) The plate-like heat insulating material is formed in at least two places over the entire length in the width direction.
[0019]
Hereinafter, specific embodiments of the present invention will be described, but the present invention is not limited to these embodiments.
[0020]
(First embodiment)
An example of the heat insulation unit of the present invention having the form {circle around (1)} is shown in FIG. In FIG. 1, 11 is a plate-shaped heat insulating material, 12 is a notch part, 13 is a suspension material. In addition, although the heat insulation unit A of FIG. 1 has connected the two plate-shaped heat insulating materials 11 with the suspension material 13, normally several to a dozen plate-shaped heat insulating materials are connected similarly.
[0021]
The plate-shaped heat insulating material 11 has a rectangular shape, and cut portions 12 are formed along the longitudinal direction from two locations on both side surfaces in the longitudinal direction. And as shown in FIG. 1, the several board-shaped heat insulating material 11 is connected and integrated in the width direction by letting the suspension material 13 pass continuously through the two notch parts 12 formed in the same side surface. ing.
[0022]
In the heat insulating material unit A of this example, the portion through which the hanging material 13 is passed through the notch 12 is short (equivalent to the thickness of the plate-like heat insulating material 11), and the hanging material 13 is viewed from the side surface in the longitudinal direction of the plate-like heat insulating material 11. It can be easily passed through the notch 12. In addition, since both the longitudinal sides of the plate-like heat insulating material 11 are connected by the two suspension members 13, the plate-like heat insulating material 11 can be stably connected and supported.
[0023]
The length of the cut portion 12 (dimension a in FIG. 1) is not less than the width of the suspension member 13, and preferably not less than twice the width of the suspension member 13. If the length of the cut portion 12 is too short, the suspension member 13 is easily detached from the plate-like heat insulating material 11, and the heat insulating unit is easily disassembled. In addition, if the notch part 12 is lengthened more than necessary, it will cause the crack of the plate-shaped heat insulating material 11.
[0024]
It is preferable to secure a distance from the widthwise end of the plate-like heat insulating material 11 of the cut portion 12 (dimension b in FIG. 1) to be equal to or greater than the thickness of the plate-like heat insulating material 11. If the cut portion 12 is too close to the end portion of the plate-like heat insulating material 11, the plate-like heat insulating material 11 will be chipped. For example, considering the case where it is necessary to adjust the width by cutting the plate-like heat insulating material in the construction of the floor heat insulation, it is preferable to secure a distance of 1 or more times the thickness further inside than the cutting position. Specifically, in consideration of the case where a plate-like heat insulating material having a thickness of 30 mm is applied to the joist portion when the joist interval is narrow, the plate-like heat insulating material is located at a position separated by 100 mm (70 mm + thickness) or more from the end in the width direction. It is preferable to form a notch.
[0025]
Next, the example of the heat insulation construction method using the said heat insulating material unit A for the heat insulation of a floor is demonstrated using FIG.
[0026]
As shown in FIG. 2A, the plate-shaped heat insulating material 11 of the heat insulating material unit A is disposed between the joists 22 disposed on the large draw 21. At this time, one end of the suspension member 13 is fixed to the upper surface of the joist 22 ′ with an adhesive or a nail, and then the slack of the suspension member 13 is eliminated, and the suspension member 13 between the plate-like heat insulating materials 11 is removed. The plate-like heat insulating material 11 is sequentially disposed. Thereby, as shown in FIG. 2 (b), the plate-like heat insulating material 11 is disposed substantially flush with the upper surface of the joists 22.
[0027]
Since the suspension member 13 is movable as described above, the suspension member 13 can be moved both in the longitudinal direction and in the width direction. Therefore, since the space | interval of the plate-shaped heat insulating material 11 can be easily adjusted by moving the suspension material 13 to the longitudinal direction, even if the width of the joist 22 is somewhat different, it can respond easily. Moreover, the fixed position of the suspension material 13 on the joist 22 can also be easily adjusted by moving the suspension material 13 in the width direction.
[0028]
Further, since the joist interval of the joist portion is generally narrower than other joist intervals, it is necessary to adjust the width by cutting a plate-like heat insulating material to be applied to this portion. In this case, since the suspension material 13 is not attached to the plate-like heat insulating material 11 and is movable, only the plate-like heat insulation material can be cut without cutting the suspension material 13. Therefore, the suspension material 13 remains on the cut surface side of the plate-like heat insulating material, and the plate-like heat insulation material can be stopped with the suspension material as it is.
[0029]
Finally, as shown in FIG. 2C, the floor material 23, which is a surface plate, is placed on the plate-like heat insulating material 11 and fixed. At this time, since the plate-shaped heat insulating material 11 is disposed in a state substantially flush with the upper surface of the joists 22, the plate-shaped heat insulating material 11 and the floor material 23 are applied in close contact with each other. In addition, since the suspension member 13 is movable, it does not require any particular stretchability in construction, and can effectively prevent the suspension member from extending and the plate-like insulation material from dripping over time. A desired heat insulating performance can be ensured.
[0030]
When the cut portions are formed along the longitudinal direction from each of the two side surfaces in the longitudinal direction of the plate-like heat insulating material as in this embodiment, the thickness is parallel to the plate-like heat insulating material 11 as shown in FIG. In addition to forming the notch portion 12 in, it can also be formed obliquely with respect to the thickness direction of the plate-like heat insulating material as shown in FIGS.
[0031]
In the heat insulation construction of the floor, the lifting force by the suspension member 13 can be increased by performing construction in such a manner that the two cut portions 12 open upward as shown in FIG. On the other hand, as shown in FIG. 4, the fixing force by the suspension member 13 can be increased by performing construction in such a manner that the two cut portions 12 open downward.
[0032]
(Second Embodiment)
Examples of the heat insulating unit of the present invention having the form (2) are shown in FIGS. FIG. 5 is an example in which the cut portion is formed in parallel to the thickness direction of the plate-like heat insulating material, and FIG. 6 is an example in which the cut portion is formed perpendicular to the thickness direction of the plate-like heat insulating material. FIG. 5 is a view as seen from the back side (lower side).
[0033]
In these heat insulating material units B and C, since the forming direction of the cut portion 12 and the movable direction of the hanging material 13 are completely coincident with each other, the movement of the hanging material 13 is extremely easy and the workability is improved. Further, since the number of the cut portions 12 (that is, the number of the suspension members 13) can be designed relatively freely, by increasing these numbers according to the length of the plate-like heat insulating material, long plate-like heat insulation Even materials can be connected and supported stably.
[0034]
Moreover, in these heat insulating material units B and C, since the interval of the plate-shaped heat insulating material 11 can be freely adjusted by moving the suspension material 13 in the longitudinal direction, the width of the joists differ slightly as described above. It is possible to easily cope with structural materials having different widths, such as columns and inter-columns. Moreover, when it is necessary to cut the plate-shaped heat insulating material 11, the hanging material 13 can be partially removed from the cut portion 12, and only the heat insulating material can be cut, and the cut surface side is also stopped with the hanging material as it is. be able to.
[0035]
【The invention's effect】
According to the heat insulating material unit of the present invention, since the suspension material is not fixed to the plate-like heat insulating material and is movable, the interval between adjacent plate heat insulating materials can be easily adjusted, and between the structural materials. When installing plate-like insulation, structural materials with different widths can be easily accommodated, and when it is necessary to cut the insulation according to the interval between the structural materials, the suspension material is cut. The plate-like heat insulating material can be cut without any problem, and the cut surface side of the plate-like heat insulating material can also be stopped as it is without using a fixing bracket or the like. Further, since the stretchability is not required for the suspension material, it is possible to solve the problem that the suspension material extends over time due to creep strain and the plate-like heat insulation material hangs down, resulting in a decrease in heat insulation performance.
[0036]
Therefore, according to the heat insulating method using the heat insulating material unit of the present invention, it is possible to construct a heat insulating structure that can efficiently perform heat insulating work and maintain desired heat insulating performance over a long period of time.
