Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a wall of a house,
The present invention relates to a heat insulating material inserted under a floor or above a ceiling. More specifically, a plate-shaped heat insulating material made of a closed-cell foam made of a synthetic resin such as an expanded polystyrene molded body has been improved so that it can be applied to an insertion method that has recently become popular. A variable width heat insulating material whose width can be changed in accordance with the interval of the mounting portion, and a width between the variable width heat insulating material and the house aggregate is increased without increasing the heat insulating property. The present invention relates to a variable heat insulating material.

[0002]

2. Description of the Related Art In the past, there have been cases where heat insulating materials have been used inside the walls of houses, under floors or behind ceilings, but recently, awareness of energy saving has increased, and heat insulating materials have been used in most houses and condominiums. And is rapidly spreading.
Various plastic foams, glass wool, rock wool, etc. are used as the heat insulating material.
From the viewpoint of economy and the like, resin foam molded articles composed of closed cell foams of synthetic resin are the most common.

[0003] Glass wool, rock wool, and the like are often used, but since they are inserted and filled in the entire space inside the wall, there is no escape place for moisture condensed inside when used for a long period of time. Accumulation in the gaps between the columns often causes accidents such as the columns being rotten by the action of the water. On the other hand, since the resin foam molded body is made of a closed cell aggregate having almost no air permeability, there is no possibility that the condensed water may accumulate in the capillary tissue, and such an accident does not occur.

For this reason, in recent years, when a heat insulating material is inserted into the inside of a wall, under a floor, behind a ceiling, or the like, a plate-shaped plastic foam molded article is inserted between columns by utilizing its slight elasticity. Attention has been paid to a method of fixing by means of this method, and since this method is excellent in heat insulation, workability and economy, it is rapidly spreading.

However, in general, the gap between the inside of a wall into which a heat insulating material is inserted, the floor or under the ceiling or the space between the joists or the ridges of the ceiling is not always constant and has a considerable variation. The molded body needs to have considerable compressibility. Therefore, there is a disadvantage that it cannot be used unless it is a foamed molded article having high elasticity, such as foamed polyethylene or foamed polypropylene.

On the other hand, from the viewpoint of physical properties as a heat insulating material,
Expanded polystyrene molded articles have been widely used in this field since they have the best heat insulating properties, handleability and economical efficiency. However, it is difficult to apply this method as it is due to lack of compressibility, and various structures such as the use of some highly elastic materials in order to compensate for the lack of elasticity have been proposed, but many problems still remain. is there.

[0007]

The foamed polystyrene molded article is the most excellent heat-insulating material in terms of heat insulation, handleability, economy and the like, but the workability is recently high due to insufficient compressibility. There are many problems when employing the insertion method that is receiving attention. The present invention has been made in view of the above problems, and allows the width of the heat insulating material to be easily changed, and the insertion method can be applied without impairing the advantages such as the heat insulating property and economical efficiency of the expanded polystyrene molded article. It is an object of the invention to develop and provide a variable width heat insulating material.

[0008]

SUMMARY OF THE INVENTION The present invention has studied a method for imparting an applicable elasticity in accordance with the distance between columns or joists when a foamed polystyrene molded article is inserted into a wall or under a floor. . As a result, the foamed polystyrene molded body was divided into a plurality of portions, and the portions were moved in parallel with each other, so that the variable-width-type heat-insulating material was adapted to the interval between the mounting locations.

The joint surfaces of the two divided members are maintained in a state of being in close contact with each other, so that no gap is generated.
In addition, it has been found that a slide structure in which the required thickness of the variable-width insulating material is maintained over the entire surface is most suitable.
Once the variable-width insulating material is once attached, the width-engaging structures formed on the variable-width insulating material are engaged with each other so that the width does not shrink, and there is a gap between the structural materials such as columns. We have also developed a structure that does not cause any problems. As a result, it became a property suitable for the insertion method, and it was found that a high heat insulating effect was obtained.

That is, the variable width heat insulating material of the present invention has a thickness, width and length as appropriate, and a rectangular parallelepiped formed of a closed-cell foam of synthetic resin is formed by an inclined slide surface which is inclined and cut in the width direction. The gist of the invention is that it is divided into a plurality of members, and the abutment position of the inclined slide surface is shifted in the width direction to adjust the width.

The variable width heat insulating material according to the present invention comprises a sliding groove and a sliding ridge which are slidably fitted in the width direction on the opposing surfaces of the two members abutting through the inclined sliding surface. A dovetail fitting comprising a sliding dovetail structure having a sliding dovetail groove and a sliding dovetail projecting part having a sliding groove structure having a cross-sectionally widened inner part. A combined sliding groove structure can also be used.

In addition, the variable width heat insulating material of the present invention comprises a guide groove having a small width and a guide ridge located at the bottom of the sliding groove structure or the dovetail sliding groove structure and parallel to the groove. The guide groove structure is slidably formed in the groove direction, and the inclined slide surface, the slide groove structure, the dovetailed slide groove structure, or the guide groove structure has a saw tooth facing the width direction between the opposing members. , A hypocycloid gear curve, a sine curve, or the like, an engaging structure may be formed to prevent the width after the plate width is adjusted from being narrowed.

In place of the above-mentioned engagement structure, an adhesive layer is provided on at least one of the opposing surfaces of the two members that abut via the inclined slide surface, for adhering the two members at a position displaced in the width direction. It is also possible to adopt a structure that prevents narrowing of the width after adjustment. In the heat insulating material of the present invention, the closed cell foam of the synthetic resin is preferably a foamed polystyrene molded article.

Here, "the rectangular parallelepiped made of a closed cell foam of synthetic resin is divided into a plurality of members by an inclined slide surface which is inclined and cut in the width direction" means that the members are stepped in the width direction. , Upward, leftward, or rightward and leftward.

The variable width heat insulating material is made of a foamed polystyrene molded article, and is fragile. To prevent damage to a portion having a sharp cross section, the sharp tip is cut off to form an obtuse angle or a right angle. Those having a shape are also included in the present invention.

Hereinafter, the present invention will be described in detail. It is preferable that the material of the heat insulating material of the present invention is made of a foamed polystyrene molded body. The composition of the polystyrene may be ordinary polystyrene, that is, a polymer obtained by polymerizing only a styrene monomer, or a high-impact polystyrene partially mixed with synthetic rubber or rubber latex.

The foam may be produced by a conventional bead foam molding method or an extrusion molding method. However, once it is installed as a heat insulating material having a variable width, no particularly high mechanical properties are required. Foaming degree (usually 10-20
Times) or a high degree of foaming (usually 30 to 50 times, sometimes 10 times)
(0 times) is preferable in terms of heat insulation and economy.

Further, even when the expanded polystyrene is formed into a molded product having an increased degree of expansion, since all the cells contained therein are composed of closed cells, there are no open cells forming a continuous capillary structure. do not do. Therefore, when used as a heat insulating material having a low thermal conductivity and a variable plate width, dew condensation water penetrates and is retained in the foam, and there is no fear that the pillars and the like will rot. These properties are superior to glass wool or rock wool used as other variable width insulation materials for construction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described more specifically with reference to the drawings.

[Embodiment 1] FIGS. 5 to 8 show a first embodiment of a variable width heat insulating material 1 according to the present invention. FIG.
FIG. 6 is an exploded perspective view of one embodiment of the variable width heat insulating material of the present invention, FIGS. 6A and 6B are a plan view and a front view, respectively, and FIG. FIG. 7 is an enlarged sectional view of a section taken along line AA in FIG. 6A in a combined state. FIG. 8 is a front view showing a state where the width of the variable-width-type heat insulating material is expanded by sliding the slide member left and right.

As shown in FIG. 5, each member is a plate-shaped foamed polystyrene molded body, which is composed of a main body 2 and two slide members 3. The side surface of the main body 2 is a trapezoidal plate-shaped molded body, and both trapezoidal slopes. As the inclined slide surfaces 10, the slide member 3 having the inclined slide surface 10 opposed to the inclined slide surface 10 is in close contact with the inclined slide surface 10, and is moved in parallel along the inclined slide surface 10 to increase the overall width. It is a structure that can be done.

A sliding groove 7 is formed on the inclined sliding surface 10 of the main body 2 so that the sliding state is maintained even when the sliding member 10 slides. A moving ridge 9 is formed and fitted so as to be slidable in the groove direction. Further, a recess 6 and a bulge 8 mesh with the edges of the sliding groove 7 and the sliding ridge 9, respectively. A dovetail-shaped fitting consisting of ridges is formed, and the structure is such that the close contact state is always maintained.

The side surfaces of the two slide members 3 are shown in FIG.
As shown in the front view, the trapezoid has a right-angled trapezoidal shape 5 having one oblique side, and two sliding ridges 9 are formed on the inclined sliding surface 10, and the swelling of the sliding ridge 9 at the edge thereof. 8 are configured.

The above-mentioned variable width heat insulating material 1 can be expanded and contracted by sliding in accordance with the width of the mounting place, and the thickness required for maintaining heat insulation is maintained. Even if the width of the variable width heat insulating material 1 is changed, the members are always kept in close contact with each other, and there is no gap between the members. The size of the sliding groove 7 and the sliding ridge 9 is not particularly limited.
The distance between the sliding grooves 7 and the sliding ridges 9 is preferably about 200 mm.

Incidentally, the variable width heat insulating material 1 shown in FIG.
Two sliding grooves 7 and two sliding ridges 9 are formed on both left and right sides. Further, when the sliding groove 7 and the sliding ridge 9 are fitted and the slide member 3 is moved in parallel along the groove direction, it has an effect of preventing deformation due to lateral vibration. Variable width thermal insulation 1
Considering the case of cutting and using an appropriate length in the vertical direction, it is preferable to further configure the fitting structure of the sliding groove 7 and the sliding ridge 9.

The sliding ridge 9 of the slide member 3 is
The slide groove 7 can be inserted along the inclined slide surface 10, and as shown in FIG. 7, the recess 6 of the edge of the slide groove 7 and the bulge 8 of the edge of the slide ridge 9 are formed. Since the parts are fitted and in close contact with each other, even if the slide member 3 is slid, the inclined slide surface 10 of the slide member 3 and the main body 2
Is always kept in close contact. This is effective for enhancing the heat insulating property, and is one of the characteristics of the sliding structure of the variable width heat insulating material of the present invention.

As shown in FIG. 8, the width of the heat insulating material of the present invention can be expanded by sliding the slide member 3 to the left and right. The structure is such that the thickness that can provide the necessary heat insulating effect is maintained within the range. This is one of the most significant features of the present invention.

In order to secure a required constant thickness even when the width of the heat insulating material 1 of variable plate width is expanded, the height of the trapezoid 4 in the front view of the main body 2 is set as shown in FIG. 3 is thicker. For this reason, it is also possible to cut and remove some portions of the upper surface of the trapezoid having a certain thickness or more to save material costs.

In order to facilitate the work of expanding the width of the heat insulating material 1 of variable plate width, a low ridge-shaped edge is formed on the edges of the slide member 3 on the left and right sides in the plan view of FIG. A handle can also be configured.

The column interval, the partition interval between them, and the like are not necessarily constant depending on the construction site. Therefore, it is necessary to adjust the width of the heat insulating material 1 with a certain width at the time of construction. In that case, the width of the variable width insulation material can be easily adjusted within a certain range at the time of construction, so it is significantly better in both heat insulation and workability than the conventional product that had to be cut each time. ing.

[Embodiment 2] FIG. 9 is an exploded perspective view showing another embodiment of the variable width heat insulating material of the present invention. FIGS. 10A and 10B are a plan view and a front view, respectively.

As shown in FIG. 9, the variable width heat insulating material 11 includes a main body 12 and a slide member 13, and both the main body 12 and the slide member 13 are made of a foamed polystyrene molded body having excellent heat insulating properties. The side of the main body 11 is shown in FIG.
As shown in the front view of (b), it is a right-angled trapezoid 14 having one oblique side, and two sliding grooves 17 are formed on the inclined sliding surface 10 on the left side thereof. Is a gouge 16.

As shown in the front view of FIG. 10 (b), the side surface of the slide member 13 is a right-angled triangle 15, and two inclined protrusions 19 are formed on the inclined slide surface 10, and the slide member 19 has a slide. A bulge 18 is formed at the edge of the moving ridge 19. In addition, the variable width heat insulating material 1 shown in FIG. 9 has two sliding grooves 17 and sliding protrusions 19 on the left side.

The slide ridge 19 of the slide member can be inserted along the inclined slide surface 10 of the slide groove 17 of the main body.
6 and the bulge 18 at the edge of the sliding ridge 19 are fitted and brought into close contact, so that even when the sliding member is slid, the inclined sliding surface 10 and the inclined sliding surface 10 of the main body are always in close contact. It is kept in the state. This is effective for improving the heat insulating property, and is one of the features of the variable width heat insulating material of the present invention.

The sliding groove 1 fitted in the same manner as in the first embodiment
7 and the sliding ridge 19 also have the effect of preventing lateral runout when the sliding portion is moved in parallel in the groove direction. Considering the case where the variable width heat insulating material is cut into an appropriate length in the vertical direction and used, this sliding groove 17 is used similarly to the case of the first embodiment.
It is preferable to further form a large number of fitting structures of the sliding protrusions 18 with the sliding protrusions 18.

As in the case of the first embodiment, the variable width heat insulating material 11 of this embodiment has a required heat insulating effect within a certain range even when the width is expanded by sliding the slide member to the left. The structure is such that the thickness that can obtain is maintained. In addition, in order to secure a constant thickness even if the heat insulating material with variable width is expanded, the height of the right-angle trapezoid 14 in the front view of the main body 12 is larger than the thickness of the slide member. For this reason, if necessary, the upper surface of the trapezoid can be cut out at several places with a certain thickness or more to save material, as in the first embodiment.

[Embodiment 3] FIG. 11 is a plan view of another embodiment of the variable width heat insulating material of the present invention, and FIG. 12 shows a portion where the sliding groove 7 and the sliding ridge 9 are fitted in FIG. It is a figure which shows the AA line expanded sectional view. In the present embodiment, a thin guide ridge 21 is formed along a direction in which the sliding member 7 slides substantially in the center of the sliding groove 7 of the main body 2 in the heat insulating material 1 having the same width as that of the first embodiment. A narrow guide groove 23 is formed along the guide ridge 21 along the direction of sliding to the approximate center of the slide ridge 9 to form a guide groove structure.

FIG. 12 is a plan view, and is an enlarged cross-sectional view of the portion where the sliding groove 7 and the sliding ridge 9 are fitted when cut along the line AA in FIG. When slides, the guide protrusion 21 is slidably fitted in the guide groove 22.

Each of the sliding groove 7 and the sliding ridge 9 is further provided with a guide ridge 21 and a guide groove 22 because, when the sliding member 3 is slid in the direction of the groove, the sliding member 3 is deformed by lateral vibration. This is for the purpose of preventing a gap from being formed between the main body 2 and the slide member 3 and reducing the heat insulating effect.

Embodiment 4 FIGS. 13 and 14 show another embodiment of the variable width heat insulating material 1 (11) of the present invention. FIG. 13 (a) is a plan view of the main body 2 and (b). Is a front view, (c)
Is a left side view, and (d) is a sectional view taken along line AA of the plan view (a). FIG. 14A is a plan view of the slide member 3,
(B) is a rear view, (c) is a right side view, and (d) is a cross-sectional view taken along line BB of the plan view (a).

This embodiment is a variable width heat insulating material basically having a structure in which a slide member is attached to only one side, similarly to the second embodiment. Variable width thermal insulation 11
Is a main body 1 constituted by a pair of expanded polystyrene.
2 and a slide member.
As shown in the front view of FIG. 3 (b), the trapezoid is substantially trapezoidal, but has a shape 14 in which the acute angle at the lower left corner has been dropped. The edge of the groove 17 is a gouge 16.

The purpose of cutting off the sharp edge is to prevent damage to the edge caused by the brittle nature of the foamed polystyrene body for heat insulation.

The side surface of the slide member 13 is shown in FIG.
As shown in the front view of FIG. 3, the shape is a shape 15 in which the sharp edge of the upper right corner is dropped, and four sliding protrusions 19 are formed on the inclined slide surface 10 of the inverted trapezoid. A bulge 18 is formed at the edge of the sliding ridge 19.

When the sliding groove 17 and the sliding ridge 19 are fitted together, and the sliding portion 13 is moved in parallel in the groove direction,
It has the effect of preventing deformation due to lateral runout, and
The bulge 18 meshes with the main body 12 and the slide member 13.
Are always kept in close contact with each other to prevent the heat insulation function from being deteriorated.

Further, a guide ridge 21 is formed along the direction in which the slide groove 17 of the main body 12 slides substantially at the center, and along the direction in which the slide ridge 19 slides substantially at the center of the slide member 13. Thus, a guide groove 22 into which the guide ridge 21 is fitted is formed.

Each of the sliding groove 17 and the sliding ridge 19 is further provided with a guide ridge 21 and a guide groove 22 because, when the sliding member 13 is slid in the direction of the groove, the sliding member 13 is deformed by lateral vibration. Body 12 and slide member 13
This is to prevent a gap from being formed between them and prevent the heat insulating effect from being reduced. The recess 16 of the sliding groove 17 meshes with the bulge 18 of the sliding ridge 19, and the guide ridge 21 and the guide groove 2
The meshing of No. 2 is the same as the structure shown in FIG.

A small bulge 24 is formed at the end of the sliding ridge 19 and a small gouge 25 is formed at the end of the sliding groove 17 for fixing the variable width heat insulating material. The variable heat insulating material is held at a fixed width. However, when it is necessary to increase the width, the bulge 24 is folded at the notch 23, and when the portion of the bulge 24 is removed, the engagement 24 and 25 come off. The slide member slides along the groove 17 so that the width can be enlarged and adjusted.

Further, on the contact surface of the guide ridge 21 and the guide groove 22, a serrated notch 26, 27 is provided on the guide ridge 21 side, and a convex portion having a shape engaged with the serrated notch 26, 27 is provided on the guide groove 22 side. 28 are formed to constitute a plate width engagement structure. When the slide member is moved in parallel along the groove in order to increase the width of the plate-width-variable heat-insulating material, the protrusion 28 slides on the serrated notch 26 and then engages with the next serrated notch 27, The variable width heat insulating material is fixed in a state where the width is widened. In other words, the variable-width insulating material of the present embodiment can be used in two types of widths: an initial wide state and a narrow state after being slid. Generally, the variable width heat insulating material can be installed in almost these two types of width.

FIG. 15 shows a state of engagement when the projection 28 of the slide member slides the serrated notch 26 of the main body. (A) shows the state of meshing when the variable width heat insulating material is narrow, and (b) shows the case where the variable width heat insulating material is widened by sliding the sliding member of the variable width heat insulating material. (C) shows the meshing state when the variable width heat insulating material becomes wide.

As shown in FIG. 15B, at the intermediate stage of the slide, the space between the main body 12 and the slide member 13 is slightly opened. The sliding groove 17 and the sliding ridge 19 are in a state where the respective gouges 16 and the bulges 18 are in close contact with each other, so that the sliding grooves 17 and the sliding ridges 19 are pushed open against this. In (c), the convex portion 28 meshes with the serrated notch 27, and the main body 12 and the slide member 13 are again brought into close contact with each other.

At the intermediate stage of the slide, stress due to elastic deformation is generated. However, when the convex portion 28 is engaged with the saw-like notch 27 again and the heat insulating material having a variable plate width is set to be wide, the stress due to elastic deformation is generated. Disappears. Therefore, once it is set to a wide width, it is necessary to apply a considerable external force to change the width again. There is no fear that it will decrease.

Since the material of the expanded polystyrene molded article is fragile, the edge portion is particularly easily damaged. Therefore, the protruding portion 28 or the tip of the saw-tooth-shaped notch 27 may be caulked or the saw-tooth-like notch 27 may be formed. Alternatively, it is easy to make a transition to the next step, and it is also possible to adopt another shape that is hard to shift once the transition is made, for example, a hypocycloid gear curve or a sine curve.

Further, the variable width heat insulating material of this embodiment has a groove 29 in the length direction. This is because the heat insulating material having a variable width is generally made of a polystyrene molded body having a high foaming degree, so that it is fragile, has low compressibility, and is easily damaged. Therefore, it is configured for the purpose of compensating for this, and is effective for preventing the occurrence of a gap between the variable-width-type heat insulating material and a column or the like, improving the adhesion and improving the heat insulating performance.

[0064]

The variable width heat insulating material of the present invention comprises a combination of a main body and a slide member. By sliding the slide member, the width of the variable width heat insulating material can be easily changed within a predetermined range. Has the ability to do. The variable-width insulating material is mainly used by inserting it into the wall of a house, etc., but the width of the variable-width insulating material is adjusted according to irregular intervals of columns or members inside the wall into which the variable-width insulating material is inserted. It is possible to attach and install the variable heat insulating material without cutting the width. Further, after the installation work, there is no gap around, so that the insulation effect can be maintained for a long period of time, and the effect after the present invention is extremely large.
