Description

  The present invention relates to a heat-insulating roof structure in which a cooling effect and a heating effect are enhanced using a heat reflecting sheet.

  As an example of a conventional roof structure that enhances the cooling effect and the heating effect, a structure in which a heat insulating material is placed on the roof material and the heat insulating material is fixed to the roof material with bolts and nuts is known.

  In the case of a factory, since the roofing material is supported without pillars in a large area, the strength of the beam supporting the roofing material is small, and this structure cannot place a thick insulation, so it is sufficient The heat insulation effect cannot be obtained.

  In addition, this structure has a problem in that since the rain and wind directly hits the heat insulating material, the heat insulating material is deteriorated by the rain and wind, the heat insulating performance is lowered with the passage of time, and the desired heat insulating effect cannot be obtained. .

  In this case, it is conceivable to cover the heat insulating material with another roofing material, but if it is covered with another roofing material, the load applied to the beam will become too heavy and the beam will not be able to withstand, so the heat insulating material must be lightened. In such a case, a sufficient heat insulating effect cannot be obtained.

  Moreover, what formed the roof with the roof material which stuck the heat | fever reflection sheet as another example of the conventional heat insulation roof structure is known.

  With this structure, rain and wind directly hit the heat reflecting sheet. Therefore, the heat reflecting sheet is damaged by rain and wind, and a desired heat shielding effect cannot be obtained in a short time.

Further, in this structure, since the heat reflecting sheet is in direct contact with the roof material, there is heat conduction between the heat reflecting sheet and the roof material, and the heat shielding (heat insulating) effect is small.

  The problem to be solved is that in the case of a building that supports the roof with a small number of pillars, such as a factory, if the roof is covered with a thick insulating material with high thermal insulation effect, the roof becomes too heavy to support the roof. Since it disappears, it is difficult to newly form a heat insulating structure having a high heat insulating effect on the roof.

  In the present invention, in the case of a building that supports the roof with a small number of pillars, such as a factory, a heat reflecting sheet is provided between the existing roof and the new roof in order to enhance the heat insulation (heat shielding) performance of the roof of the building. Is the most important feature.

  More specifically, the present invention relates to a first roof, a plurality of beam-like members provided substantially in parallel on the first roof, and a second roof attached on the beam-like member. And a heat reflecting sheet provided between the first roof and the second roof, the heat reflecting sheet being integrated with the porous resin sheet and the front and back surfaces of the porous resin sheet A space for holding still air is formed on at least one of the front and back surfaces of the heat reflecting sheet.

  Here, the first roof may be an existing roof, and the second roof may be a new roof. In addition, the first roof is a folded plate roof, the beam-shaped metal fitting is connected to a peak portion of the first roof via a connection metal fitting, and the heat reflecting sheet is formed from the second roof and the beam-like shape. It may be held between metal fittings. The first roof is a wave slate roof, the beam-shaped metal fitting is connected to a hook bolt of the first roof via a connection metal fitting, and the heat reflecting sheet is supported on the upper surface of the beam-shaped metal fitting. It may be. The first roof is a tiled-roofed roof, the beam-shaped metal fitting is connected to a rib portion of the first roof via a connection metal fitting, and the heat reflecting sheet is formed between the second roof and the beam. It may be held between the metal fittings.

  Since the roof structure of the present invention includes the heat reflecting sheet on the inner side of the second roof, even when the outdoors is hot, the external heat that has entered the indoor side through the second roof is heat. It is reflected to the outdoor side by the reflection sheet. Therefore, there is an advantage that the indoor is not easily heated by the outdoor heat, and the cooling cost can be reduced when the indoor is cooled.

  Moreover, since the roof structure of the present invention includes the heat reflecting sheet on the inner side of the second roof, even when the outdoors are cold, the cold is reflected toward the outdoors by the heat reflecting sheets, or from the indoor Heat that escapes to the outside is reflected indoors by the heat reflecting sheet, preventing indoor heat from escaping to the outdoor side, making it difficult for the indoors to get cold. There is an advantage that less.

  Further, since the roof structure of the present invention has a space for holding still air on at least one of the front and back surfaces of the heat reflecting sheet, even if there is a temperature difference between indoor and outdoor, The advantage is that heat transfer by convection is low, heat transfer between indoor and outdoor is suppressed, the indoor is not too hot or too cold, and the cooling and heating efficiency is good when cooling and heating There is. .

  In the roof structure of the present invention, since the second roof is provided above the heat reflecting sheet, the heat reflecting sheet is protected from wind and rain, is prevented from being damaged, and the heat reflecting ability of the surface is maintained. Has the advantage of enduring the use of

  Moreover, since the roof structure of this invention has a 1st roof under the heat | fever reflection sheet, a heat | fever reflection sheet | seat is protected from the dirt substance contained in the air of indoor side, and the heat | fever reflective capability of a surface over a long term. There is an advantage that the heat shielding (insulating) effect is maintained over a long period of time.

  Moreover, since the heat | fever reflection sheet is supported by the beam-shaped metal fitting, the roof structure of this invention has the advantage that a heat | fever reflection sheet is hold | maintained without drooping.

  The purpose of enhancing the heat insulation effect of the existing roof was realized without impairing the durability of the heat insulation (heat insulation) structure over a long period of time by using a lightweight material called a heat reflecting sheet.
