Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a heat insulating and sound insulating member provided under each floor or in a wall of a building.

(Prior art) In order to insulate and retain heat in buildings, it has been common practice to install heat insulating mats under the floors or inside walls. and those shown in Japanese Utility Model Application Publication No. 1805/1983.

Japanese Utility Model Publication No. 57-44009 discloses that a cover having a bag-shaped portion is formed by pasting together sheets with different width dimensions, and a pillar member is inserted with a pine-shaped heat insulating material inserted into the bag-shaped portion. The installation is shown by inserting a pine-like heat insulating material between them.

According to such a structure, the cover has a degree of freedom of deformation corresponding to the extension of the folding folds, so even if the inner gap between the column members is narrower than the standard dimension,
By compressing the heat insulating material in the width direction in accordance with the deformation of the cover, the heat insulating material is installed between the column members in a completely fitted state.

However, this insulation material is only held by a cover formed by a sheet, and the installation condition is unstable. Especially when the distance between the column members is larger than the width dimension of the insulation material, Both ends of the insulation material do not come into contact with the pillar members, and the insulation material is suspended in the air and supported by the thin sheet, resulting in the inconvenience that it cannot be stably fixed between the pillar members.

On the other hand, what is shown in Utility Model Application Publication No. 60-1805 is to install a heat insulating material receiver between the beams of a building.
The insulation receiver is adapted to hold the insulation. According to such a structure, the insulation material can be fixed in a stable state, but since the insulation material receptor shown here is almost impossible to deform, there is a large variation in the dimensions between the crosspieces. In some cases, the dimensions of the receiver and the dimensions of the crosspieces do not match, making installation difficult.

On the other hand, it has been desired to provide a sound insulation structure that has the function of blocking noise from outside the building or from adjacent rooms in addition to the above-mentioned heat insulation.

(Purpose of the invention) In view of the above circumstances, the present invention has excellent heat insulation effect, sound absorption/insulation effect, and can be easily and stably installed even when the dimensions of building aggregates vary. The purpose is to provide thermal and sound insulation materials for buildings.

(Structure of the invention) The invention consists of a flexible material with deformable and restoring properties, and consists of a pair of ears that are each fixed to the surface of the building aggregate, and a pair of ears that protrude from both ears and are placed between the aggregates. The cover is integrally molded so as to maintain its shape without being subjected to external force, and the distance between the ear parts changes as a result of the deformation. A heat-insulating sound-absorbing material and a sound-insulating sheet are arranged in layers inside the protrusion.

According to this configuration, the sound-absorbing and heat-insulating material performs heat insulation and heat retention, and the noise from outside the building or from an adjacent room is absorbed by the sound-absorbing and heat-insulating material and is blocked by the sound-insulating sheet. Furthermore, the cover that holds the sound absorbing and heat insulating material and the sound insulating sheet is already integrally molded in a shape having both ear parts and a protruding part in a state before installation, that is, in a state where it is not subjected to external force, and is made of aggregate. It is formed so that the distance between both ears fixed to the surface of the aggregate changes, and even if the distance between the aggregates varies, it deforms according to the distance, so it can be easily and stably maintained. Can be installed.

(Example) Embodiments of the present invention will be described based on the drawings.

In FIG. 1, reference numeral 1 denotes joists (aggregate) placed under the second floor of a building, and between each joist 1, a heat insulating and sound insulating member 2 of the present invention is provided.

The heat insulation and sound insulation member 2 includes a thin plate-like cover 3 made of a flexible material such as synthetic resin. This cover 3 is made of a flexible material so that it can be bent by applying force from the left and right, up and down directions, and its length can be changed according to the distance between the joists. It is more preferable to use a sheet-like material made of a material having restorability, such as polyvinyl chloride, polyethylene, polypropylene, or various other synthetic resins.
This sheet-like body made of synthetic resin itself is
Although it does not have vibration-proofing or sound-proofing properties, it has excellent water resistance and durability, so it is advantageous in terms of handling.Furthermore, it is a flexible material with resilience, so it can be used between the joists. It is ideal as a cover for heat insulation and sound insulation parts.

This cover 3 consists of ears (fixed parts) 31 at both ends that are fixed to the upper surface of the joists 1, and protruding parts 32 that protrude from these ears 31 into between the joists 1, as shown in FIG. It is free in the direction perpendicular to the page. Therefore, this cover 3 can be slightly deformed when both ear parts 31 receive a tensile force or compressive force in the left-right direction in the figure, and the distance between both ear parts 31 changes due to this deformation. It's getting old. For example, in FIG. 1, the side wall 3 of the protrusion 32
2a is slightly inclined, and the cover 3 is fixed with a gap a formed between the joist 1 and the bottom of the protrusion 32. However, if the spacing between the joists 1 is narrower than in the figure, the above The cover 3 is fixed with almost no gap, that is, with the side wall 32a of the protrusion 32 being substantially vertical and in contact with the side surface of the joist 1. Note that the means for fixing the both ears 31 may be any commonly used means, such as fixing them to the upper surface of the joist 1 with double-sided tape or adhesive.

In the protruding part 32 of this cover 3, the protruding part 32
A sound insulating sheet 4 having approximately the same area as the sound insulating sheet 4 is laid down, and a pine-shaped sound absorbing heat insulating material 5 is placed on top of the sound insulating sheet 4, so that the two are superimposed in a layered manner. The sound insulation sheet 4 is made by kneading metal powder such as lead into a relatively inexpensive soft synthetic resin sheet (for example,
45063), and the sound absorbing and insulating material 5 is
Ideal heat insulation and sound absorption effects can be obtained by using a synthetic resin foam board such as urethane or a mat made of glass wool, but other well-known materials may be used.

In addition, when placing the heat insulation and sound insulation material of the present invention between the joists 1, as shown in FIG.
A vibration isolating member 33 can also be interposed between the floor joist 1 and the top surface of the joist 1. In this case, there is an advantage that light vibrations of the subfloor board 6, etc., as shown in FIG. be. As the vibration isolating member 33, a fiberboard made of high-density pine-like glass fiber or mineral fiber, a rubber plate, a foam plate, felt, or other various materials having vibration-proofing properties are used. It is possible. Such a vibration isolator may be placed between the ear portion 31 of the cover 3 and the joist 1 when installing the heat insulation and sound insulation member 2, or may be placed between the ear portion 31 of the cover 3 and the joist 1. It may be attached in advance using adhesive, adhesive tape, or other appropriate means.

A subfloor board 6 as shown in FIG. 3 is laid on top of the heat insulation and sound insulation member 2 placed between each joist 1 in this way, and a floor finishing material (not shown) is laid on top of it. I'll do what I do.

According to the above structure, the sound-absorbing heat-insulating material 5 insulates and heats the room, and noise from the second floor of the building is absorbed by the sound-absorbing heat-insulating material 5 and blocked by the sound-insulating sheet 4. Therefore, almost no sound propagates to the first floor, resulting in an extremely excellent sound insulation effect. Moreover, the cover 3 that holds the sound insulating sheet 4 and the sound absorbing heat insulating material 5 can be slightly deformed, and the distance between the ear parts 31 can be adjusted within a predetermined range, so even if the distance between the joists 1 varies The heat insulating and sound insulating member 2 can be attached easily and in a stable manner.

In addition, the vibration isolating member 3 as shown in FIG.
3, it is possible to make it difficult for light vibrations of the floor base plate 6, etc., which occur during walking, to propagate, and thereby it is possible to obtain a noise reduction effect during walking.

Although the heat insulation and sound insulation effects can be obtained even if the sound insulation sheet 4 and the sound absorption heat insulation material 5 are arranged upside down, the sound insulation sheet 4 is generally heavier than the sound absorption heat insulation material 5, and the sound absorption heat insulation material 5 is easily deformed. Because the structure
It is more preferable to lay the sound-absorbing and heat-insulating material 5 on the sound-insulating sheet 4 as described above.

It goes without saying that the application of the heat insulation and sound insulation member 2 of the present invention is not limited to the area under the second floor floor, but, for example, if it is placed under the first floor floor, the heat insulation and sound insulation effect of the basement can be obtained. Furthermore, as shown in FIG. 4, heat and sound insulation members 2 are arranged between the studs (aggregate) 7 of the building in the same manner as above, and outer wall materials 8 are arranged on the outside and inner wall base plates 9 are arranged on the inside. If you do this,
It can also be applied inside the wall, making it possible to block out noise from outside the building or from adjacent rooms. In addition, two or more covers 3 having the above-mentioned shape are formed continuously and integrally to form a structure in which a plurality of protrusions 32 are arranged at predetermined intervals, and such a single cover can be used to connect three or more bones. Even if it is fixed across the material, the same effect as above can be obtained.

(Effects of the invention) As described above, the present invention has excellent heat insulation and sound insulation effects because the heat insulation and sound absorbing material and sound insulation sheet are arranged in layers within the protrusion of the cover that is fixed to the surface of the aggregate. can get. Moreover, the cover is made of a flexible material with resilience and is already integrally molded into a shape having both ear parts and a protruding part before being subjected to external force before being installed. The distance between the ears can be adjusted within a predetermined range, so even if the distance between the aggregates varies,
This has the effect of allowing easy and stable installation.
