Description

The present invention relates to a structure for suppressing the transmission of heat from a house material heated by the sun to a room directly or through a ceiling material, and is particularly applicable to an existing structure. The present invention relates to an attic insulation structure capable of reducing heat input into a room mainly due to radiant heat transfer.

In recent years, high insulation of houses has become important from the viewpoint of energy saving. The parts to be thermally insulated include a roof, a wall, a floor, and the like. In particular, attic insulation during the daytime in summer is effective for reducing the indoor temperature.

As a conventional heat insulation technology, increasing heat insulation performance by devising heat insulation materials has been actively developed.
As a method that has been used for a long time, a method of laying a heat insulating material made of glass wool or the like on a ceiling plate is often used (prior art 1).

技術 Further, there is a technique for laminating a heat insulating material and a reflecting material on a cement-based plate material to provide a roof material having excellent heat insulating properties for the purpose of attic insulation (see Patent Document 1).

Further, a heat insulating material is attached to the back surface of the wall or the roof panel, and a sheet covering the heat insulating material is provided with a gap on the inner surface to create a space connected in the vertical direction. A technique aiming at cooling by a tunnel effect airflow has been proposed (see Patent Document 2).

In addition, a highly airtight and highly heat-insulated house is proposed, in which a highly airtight aluminum-coated heat insulation board extending from the wall to the roof is provided so as to form a ventilation layer between the outer wall and the roof, and the outer shell of the house has a double wall structure. (See Patent Document 3).

In addition, a technique is known in which a plurality of layers of aluminum foil or aluminum vapor-deposited sheets are stacked, and an air-permeable layer is formed between the sheets with upright pieces to perform heat insulation (see Patent Document 4).

The prior art 1 is simple and easy to use because it is simply placed on the floor above the ceiling. However, since fine fibers are used, there is a risk of flickering and scatter of fibers that pierce the skin. Also, the heat shielding property against radiant heat is not sufficient.
In addition, all of the prior arts described in the above-mentioned patent documents have been devised as materials, but the devising of the installation work is insufficient, which requires time for the construction, and particularly, the retrofitting of the existing house is required. It is difficult to apply as construction.

As explained above, the conventional heat insulation technology is biased toward material and structural innovation, and the improvement of construction technology is neglected, leaving a problem in time and cost, and also difficult to apply flexibly. There were also some problems.

The present invention has been made in view of the above points, and it is an object of the present invention to provide an attic insulation structure which is highly effective, can be easily and inexpensively constructed with simple construction.
In particular, the most effective countermeasure against the rise in room temperature in summer is to control the heat input from the roof, but an inexpensive heat insulation method has not been realized.

The present invention makes it possible to easily perform the laying work and also to easily perform post-construction on an existing house.
Attic insulation work is narrow and has many obstacles, sometimes work at high places, so it is easy to carry out work, it has large dimensional tolerance, it is easy to carry into narrow space and install it in a large area, It is very important that the heat insulation performance does not decrease even if the construction is performed with low dimensional accuracy, and the present invention makes this possible.

A roofing material and / or a purlin so that a flexible heat-insulating piece of long sheet having at least one surface formed on a low emissivity surface is opposed to the roof back surface and / or the ceiling back surface on the inner surface of the roof of the existing house. And / or driving a U-shaped needle or / and a screw or / and a nail into a rafter or / and a purlin or / and a ceiling material // a beam or / and a field edge as a stop member of the heat-insulating piece of cloth long sheet. It was configured to be attached and laid.

In addition, a configuration in which the piece of heat-insulating cloth long sheet is attached and laid by applying a tape as a stopper member and / or applying an adhesive material (claim 2), or being sandwiched by a cord-like body as the stopper member. There is a configuration that is attached and laid (claim 3).

In addition, in the attic insulation structure according to any one of claims 1 to 3, a plurality of cloth long sheets for heat insulation are laid and laid in a superposed state, and the laid portion is laid by attaching the superposed portion with the stopper. There is item 4).

The surface member of the heat-insulating cloth long sheet may be any material as long as the effect of radiant heat shielding can be expected, and may be a metal-based film such as aluminum or copper, or a painted surface in which these pieces are mixed, Most preferably, the surface has a gloss.
Further, the emissivity is preferably 0.5 or less, and more preferably 0.3 or less, and it is more preferable that the emissivity of the surface of the heat-insulating piece long sheet facing the roof is equal to the heat-insulating piece length. Most preferably, the emissivity is equal to or lower than the back surface of the shaku sheet.

In the attic insulation structure of the present invention, since at least one side is formed of a flexible long piece of heat-insulating piece of heat-insulating cloth, there are many obstacles and the attic is sometimes required to work at heights. The safety and workability of the insulation work is improved, and the work can be performed by folding or wrinkling.Therefore, there is a high degree of freedom in the work, and it can be carried into a narrow space and easily installed in a large area. High attic insulation can be implemented.

In addition, the laying work is simple because the heat-insulating cloth sheet is directly attached to the roof material, the roof frame material, or the ceiling material or the ceiling frame material so as to face the back surface of the roof and / or the back surface of the ceiling. Can be done.
In particular, measures to raise the room temperature in the summer, such as factories, warehouses, and barns where roof materials are exposed indoors, without ceiling panels, can be implemented inexpensively and easily, and post-installation of sheet insulation on existing houses There is also an advantage that it becomes possible.

Therefore, according to the present invention, attic insulation during the daytime in summer, which is very effective in reducing the cooling load, can be achieved simply, safely, and inexpensively, and the thermal working environment of the factory can be improved, It can avoid the hot summer environment in summer, and can greatly contribute to energy saving by high insulation of houses, which is an important theme for protecting the global environment.

Hereinafter, an embodiment will be described with reference to the drawings to facilitate the description.
FIG. 1 is an overall view of an attic insulation structure according to a first embodiment of the present invention applied to a general house.

In this first embodiment, the heat-insulating piece long sheet 1 for heat insulation substantially faces the entire area of the back surface 9 of the roof, and a ridge 91 and a hut beam 92 as a roof frame supporting the roof material 90 and a ridge 93 are formed in a U-shape. By directly hitting with a needle (referred to as a tucker in the market), the heat-insulating cloth long sheet 1 is laid so as to cover the roof back surface 9, and heat input into the room is cut off.

In this case, it is not always necessary to provide a gap between the heat insulating sheet 1 and the back surface of the roofing material 90, and the heat insulating sheet long sheet is used so that the heat insulating sheet 1 contacts the rear surface of the roof frame material 90. 1 may be directly attached to the back surface of the roofing material 90 by driving a U-shaped needle or the like.
When it is necessary to mount the device on hard wood or a knot, it is preferable to use a screw or a nail instead of the U-shaped needle.

In addition, when attaching the heat insulating cloth long sheet 1 to the ridgeboard 91 and the hut beam 92 as the roof frame supporting the roofing material 90 and the roofing frame 90 that supports the roofing material 90, and the ridgewood 93, they are directly adhered with tape or an adhesive material. You may do it.
In addition, it is preferable that the tape or the adhesive be heat-resistant in an attic environment where the temperature is high.

反 The heat-insulated cloth long sheet 1 is a strong sheet woven of synthetic fiber or glass fiber, coated with aluminum paint on both sides, and has a front and back surface with an emissivity of about 0.3. If only one side is coated with aluminum paint, it is important to lower the emissivity of the solar heat input side. The heat-insulated cloth long sheet 1 is laid with the side on which the surface is coated facing the roof surface, that is, the upper surface.

The surface member of the low-emissivity sheet may be any material as long as the effect of radiant heat shielding can be expected, and may be a metal-based film such as aluminum or copper, or a painted surface mixed with these pieces. Most preferably, the surface is raised.
In addition, the emissivity is preferably 0.5 or less, and more preferably 0.3 or less, and it is more preferable that the emissivity of the surface corresponding to the roof of the sheet is equal to or lower than the back surface of the sheet. Most preferably, the emissivity is used.

In order to improve the workability, the heat-insulated piece of cloth long sheet 1 weighs about 10 kg or less and is easy to handle by hand. It is long and roll-shaped considering the construction of the attic. A plurality of such sheets may be connected to each other so that the connection gap between the sheets is reduced as much as possible.
In this case, as is often done with ordinary tent sheets and the like, the ends of the cloth-like sheet are drilled at an appropriate pitch, the holes are reinforced with eyelet ring fittings, and the sheets are passed through a rope through the ring to connect the sheets. The use of a connected sheet makes it easy to construct and a strong sheet.
In addition, as means for connecting the sheets, a tape or a string may be used, and it is preferable to use a heat-resistant adhesive tape as the tape.

In addition, the purpose of the present invention and the use environment of the heat-insulating cloth sheet 1 are mainly radiation shielding at a wavelength in the far-infrared region of 150 degrees or less in the attic, and reflection in the visible light region of sunlight. Since there is almost no color effect as described above, it is almost meaningless to make the sheet white to reduce the emissivity.

In the first embodiment, the hanging metal fittings 50 are attached to the hut beam 92 and the purlin 93 as the roof frame, and the long metal sheet 5 for heat insulation is also hung on the hanging metal fittings 50 to form a two-layer heat insulating sheet. It is formed in the attic insulation structure of 1,5.
In this way, by providing a plurality of layers of heat-insulating cloth long sheets 1 and 5, the effect of suppressing solar heat input can be improved.

Next, FIG. 2 is an overall view of an attic insulation structure according to a second embodiment of the present invention applied to a general house.

In this case, it is not always necessary to provide a gap between the heat insulating cloth long sheet 2 and the back surface of the ceiling material 81, and the heat insulation cloth long sheet 2 contacts the rear surface of the ceiling material 81 so as to be in contact with the heat insulating cloth long sheet 2. The cloth material long sheet 2 may be directly attached to the back surface of the ceiling material 81 by driving a U-shaped needle or the like.

In the second embodiment, a structure in which the underside of the roof 9 shown in the first embodiment is covered with the attic heat-insulating structure that covers the long backing sheet 1 for heat insulation can be used.

Next, FIG. 3 is a partial perspective view of the attic insulation structure according to a third embodiment of the present invention applied to a general house, as viewed from below.
In this case, the string-like body 6 is stretched under tension along the hut beam 92 serving as a roof frame material under the heat-insulating sheet 3 facing the entire area of the roof back surface 9. 6, the heat-insulating cloth long sheet 3 is sandwiched between the corners of the hut beam 92, so that the heat-insulating cloth long sheet 3 is laid so as to cover the roof back surface 9, and the heat input to the room is blocked. I have.

In addition, the attachment by the string-shaped body 6 can be applied to the case where the heat-insulating cloth sheet is attached to the back of the ceiling. In this case, the heat-insulating cloth sheet is attached to the ceiling plate by the string-like body. And between the ceiling beam and field edge.

紐 Note that the string-shaped body includes a wire, a string, and the like, but may be any as long as it can support a heat-insulating piece of cloth long sheet.

In the third embodiment, the roof attic insulation structure for covering the roof back surface 9 shown in the first embodiment with the thermal insulation long sheet 1 or the ceiling back surface 8 shown in the second embodiment is used for the thermal insulation fabric. The structure can be combined with the attic insulation structure covered with the long sheet 1.

Although the embodiment of the present invention has been described above, the present invention can be applied not only to the attic insulation of ordinary houses, but also to the attic insulation of buildings with exposed roofs such as factories, warehouses, and barns. It is also applicable to attic insulation in concrete structures.

母 Also, the base material of the heat insulating cloth long sheet is not particularly limited, but the temperature rises to nearly 100 degrees depending on the conditions. In this case, it is necessary to select a material in consideration of heat resistance. The easiest way to lower the emissivity of the sheet is to apply aluminum paint, but for the purpose of lowering the emissivity, aluminum foil may be attached to the surface layer, or various metals such as zinc, copper, titanium, etc. It is also possible to reduce the emissivity according to the application.

Further, in the embodiment, the heat insulating cloth long sheet is laid so as to substantially face the entire area of the roof back surface or the entire area of the ceiling back surface, but a part of the roof back surface, for example, a ceiling portion of a living room or a bedroom. The present invention also includes a device that is partially laid so as to face each other.

In addition, regarding the laying direction of the heat insulating cloth long sheet, for example, the longitudinal direction of the heat insulating cloth long sheet is set to the longitudinal direction of the rafter or the beam, or the direction perpendicular to the longitudinal direction of the rafter or the beam.
