Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor insulation method for a building, particularly a wooden building. More specifically, the present invention relates to a floor heat insulation method capable of easily constructing a floor structure having high heat insulation properties.

[0002]

2. Description of the Related Art In recent years, from the viewpoint of improvement of livability and energy saving, the demand for high heat insulation in buildings, especially houses, has been increased, so that fiber insulation and synthetic resin foam insulation have been installed under floors and the like. Became. These insulation materials
Generally, it is installed between floor support members such as large pulls and joists.
At this time, if there is a gap between the floor base material and the heat insulating material, the heat insulating property is reduced due to the inflow of cool air. Therefore, it is important to make the upper surface of the support member and the upper surface of the heat insulating material flush.

[0003] However, although the fiber-based heat insulating material is relatively inexpensive, it is difficult to construct it so as to be in close contact with the floor base material because it is very soft.

On the other hand, a synthetic resin foam heat insulating material is hardly deformed by its own weight, and therefore can be particularly preferably used for heat insulation under the floor. Further, as a method of making the upper surface of the synthetic resin foam heat insulating material flush with the upper surface of the support member, Japanese Utility Model Application Laid-Open No. 59-54645 discloses a method in which the upper surface of the heat insulating material is made flush with the upper surface of the support member by using a receiver attached to a joist. It is disclosed to be one.

Further, in Japanese Patent No. 2693503, 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 closely adhered with good workability. A method is disclosed for causing this to occur.

On the other hand, in recent years, labor saving of wood processing at construction sites by pre-cutting building materials has been the mainstream, and even in floor structures, joists which are difficult to pre-cut have been omitted, and floor base materials have been directly stretched over large pulling. The so-called joist-less construction method is spreading.

However, when heat insulation is performed by the joist-less construction method, the joists cannot support the heat insulating material, and therefore, it is necessary to perform the work directly on the gibiki. It is difficult to construct so as to be in close contact with the flooring material.

When a heat insulating unit conforming to the joist-less construction method is manufactured with the configuration of the above-mentioned Japanese Patent No. 2693503, one of the heat insulating materials suitable for a general span is 900 sheets in width.
Due to the large length of about 1 mm and the length of about 1800 mm, the heat insulating unit to which a plurality of heat insulating materials are connected is rather difficult to handle and the workability is poor.

As described above, in the joist-less construction method, a floor insulation construction method capable of easily constructing a floor structure having high heat insulation properties has not been found yet.

[0010]

SUMMARY OF THE INVENTION An object of the present invention is to provide a floor insulation construction method capable of easily constructing a highly heat-insulating floor structure in which a synthetic resin foam insulation material and a floor base material are in close contact in a joist-less construction method. Is to provide.

Means for Solving the Problems The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and as a result, inserted a synthetic resin foam heat insulating material between the bridges to form a floor base material on the bridge. In the method of stretching, when the thickness of the synthetic resin foam heat insulating material is a and the width dimension is b, for example, when the rectangle formed by the large scale is a rectangle, the parallel sides forming the long sides of the rectangular void are parallel to each other. 2
During the pulling of the book, a stretchable suspending material is stretched preferably in a direction substantially parallel to the short side direction, and the synthetic resin foam heat insulating material is placed on the hanging material. Further, the length c of the part of the hanging material extending from the large pulling end to the other large pulling end is a + b.
When it is set so as to satisfy ≦ c ≦ 2a + b, it has been found that a floor structure having high heat insulation can be easily constructed, and the present invention has been completed.

That is, according to the present invention, in a construction method in which a synthetic resin foam heat insulating material is inserted between the pulleys and the floor base material is stretched on the pulley, a pair of rectangular sides formed by the pulley are formed. A method of spanning a stretchable suspending material between at least two parallel pulleys, arranging a synthetic resin foam insulation material on the suspending material, and then stretching a floor base material on the pulley. So,
Assuming that the thickness of the synthetic resin foam heat insulating material is a and the width is b, the length c of the portion of the hanging material spanned from the large end portion to the adjacent large end portion is as follows. Relational expression of a
+ B ≦ c ≦ 2a + b The present invention relates to a floor heat insulation method characterized by being set so as to satisfy (b).

According to the present invention, in the first aspect of the present invention, the rectangle formed by the pulling is a rectangle, and the suspension having extensibility is provided between the two pulls parallel to each other forming the long side of the rectangle. The present invention relates to a floor heat insulation method characterized in that a material is bridged substantially parallel to the short side direction (claim 3).

Further, the present invention relates to the floor insulation method according to the first to third aspects of the present invention, wherein the hanging members are a plurality of tape-shaped hanging members which are stretched substantially in parallel with each other (claim 4).

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
It shows a construction method until a synthetic resin foam heat insulating material is inserted between the pulleys and the floor base material is stretched over the pulley after the pulling is performed.

In the first step, first, a suspending member for arranging the synthetic resin foam heat insulating material in a rectangular space such as a rectangle of the bridge is stretched over the bridge, and the bridge and the hanging member are fixed.

In this case, the hanging material is hung between two parallel pulleys forming a pair of sides of a rectangular gap formed by pulling, preferably in a direction substantially parallel to the other pair of sides. Passed. A rectangle is often a rectangle, and in this case, it is stretched substantially in parallel with the short side direction between two parallel parallel pulleys forming the long side of the rectangular gap formed by the pullout. Is preferred. If it is stretched between two parallel pulleys constituting the short side, the vicinity of the central portion of the synthetic resin foam heat insulating material may be slightly bent and a gap may be formed between the synthetic resin foam heat insulating material and the floor base material. Not preferred.

The shape of the hanging material used in the present invention is as follows.
A sheet or tape is preferable because it does not cause unevenness of the floor even if it is sandwiched between the puller and the floor base material and can firmly hold the synthetic resin foam heat insulating material. The upper limit of the thickness of the hanging material is preferably 1 mm or less, and more preferably 0.5 mm or less so as to prevent the floor from becoming uneven. The lower limit of the thickness of the hanging material may be any strength as long as the synthetic resin foam heat insulating material can be held for a long time, and it depends on the material of the hanging material, but is preferably 0.01 mm or more.

The suspending material used in the present invention may be a single film having a width approximately equal to the longitudinal dimension of the synthetic resin foam heat insulating material, but from the viewpoint of economy and workability.
It is preferable that the tape-shaped suspending material is a plurality of tape-like hanging members that are wound substantially parallel to each other. There is no particular limitation on the width of the tape-shaped hanging member, but from the viewpoint of strength and workability, the width is 30 mm or more and 500 mm or more.
mm or less is preferable.

The position where the hanging material used in the present invention is laid is not particularly limited. However, in order to prevent a gap from being formed between the synthetic resin foam heat insulating material and the floor base material due to the deflection, at least the synthetic material is used. It is preferred that the resin foam heat insulating material be stretched over both ends in the longitudinal direction and near the center.

The suspending material used in the present invention has stretchability, and is preferably made of synthetic resin or rubber. As the material, for example, polyethylene resin, polypropylene resin, polyvinyl chloride resin,
Examples include polyurethane, natural rubber, synthetic rubber, and thermoplastic elastomer. Even if the material itself has poor stretchability, it can be suitably used as long as it exhibits stretchability as a woven or nonwoven fabric.

Next, the suspension material is roughly fixed, and then a synthetic resin foam heat insulating material is placed on the suspension material, and the floor base material is stretched.

The synthetic resin foam heat insulating material used in the present invention includes polystyrene resin foam, polypropylene resin foam, polyethylene resin foam, polyurethane foam, and phenol resin foam. Among these, a polystyrene resin foam and a polypropylene resin foam are preferred. The thermal conductivity of the synthetic resin foam heat insulating material is not particularly limited, but a lower thermal conductivity is preferable because the thickness can be reduced, the weight is reduced, and handling becomes easier.

Since the synthetic resin foam heat insulating material used in the present invention is inserted into a rectangular space such as a rectangle formed in a large scale, the shape is slightly smaller than the rectangular space. If it is too small, the gap between the synthetic resin foam heat insulating material and the pulley becomes large, resulting in poor heat insulation. Specifically, each piece of synthetic resin foam insulation,
It is preferable that 90% to 99% of each of the rectangular pieces formed by the above-mentioned general rule.

If the thickness of the synthetic resin foam heat insulating material is a and the width is b, the length of the suspension member between the two large pulls from the large pull end to the other large pull end is determined. The length c of the part bridged between them satisfies the relational expression of a + b ≦ c ≦ 2a + b. In the case of c = a + b, the synthetic resin foam heat insulating material is disposed so as to protrude from the upper surface of the bulk by almost half the thickness, and in the case of c = 2a + b, the upper surface of the synthetic resin foam heat insulator is rough. It is almost flush with the upper surface of.

In a state where the synthetic resin foam heat insulating material protrudes from the upper surface of the large resin, the floor material is put on the synthetic resin foam heat insulator and the floor material is pushed in until it comes into contact with the large material. After being stretched, the synthetic resin foam heat insulating material is held in a state where there is no gap with the floor base material. Naturally, even when the upper surface of the synthetic resin foam heat insulating material is substantially flush with the upper surface of the large structure, the floor base material is stretched without gaps with the synthetic resin foam heat insulating material.

As described above, according to the construction method of the present invention, in the so-called joist-less construction method in which the floor base material is directly stretched on the pulling bar, the synthetic resin foaming is performed without forming a gap between the floor base material and the floor base material. It becomes possible to insert and arrange the body heat insulating material in the guide.

In the construction method of the present invention, since the hanging material is stretched and fixed, and the synthetic resin foam heat insulating material is simply inserted between the pulling frames, at least until the floor material is stretched. Completely one-person work is possible, and the workability is excellent.

Further, if three or more wires are stretched and stretched using a long suspending material to form two or more places where the synthetic resin foam heat insulating material is disposed, the workability is further improved. At this time, it is preferable to fix all portions where the pulling and the hanging material overlap.

Further, if a hanging material which is marked in advance is used so that a portion overlapping with the pulling and a portion bridging between the pulling can be recognized, the pulling is measured while measuring the length of the lifting material at the construction site. It is possible to save time and effort for fixing the work piece, and to further improve workability.

Although the present invention is used in the so-called joist-less construction method, it can be similarly applied to a construction method using a joist. In this case, the hanging material is hung over the joist, not oversized. However, when the method is applied to a method using a joist, the number of synthetic resin foam heat insulating materials increases, and workability deteriorates.

In the present invention, as in Japanese Patent No. 2693503, a unit in which a plurality of plate-like heat insulating materials are connected by a suspending member may be formed in advance, and the unit may be fixed to the structural member by the suspending portion. However, as described above, generally, one heat insulating material that fits the main room is as large as about 900 mm in width and about 1800 mm in length. Therefore, the heat insulating unit to which a plurality of heat insulating materials are connected is Rather, it is difficult to handle and the workability is poor.
