Description

  The present invention relates to a heat shield and a heat shield provided with a heat shield main body attached to the back surface of the roof base plate and an eaves side heat shield attached to the eaves portion of the roof continuously to the heat shield main body. It relates to a roof structure with materials.

  Conventionally, a heat insulating material such as glass wool is laid on the upper surface of the ceiling board in order to ensure the heat insulating property of the indoor space. In addition, a ventilation space is provided at the joint where the ceiling and the roof intersect for ventilation of the hut space.

  However, if the thickness of the heat insulating material laid on the top surface of the ceiling plate is increased in order to improve the airtightness and heat insulating properties of the house, the portion where the ceiling and the roof intersect with each other is blocked by the heat insulating material. There was a case where a ventilation space for ventilation of the back space could not be secured.

Therefore, a ventilation spacer made of relatively hard paper such as corrugated cardboard or cardboard, or relatively soft plastic board is installed between the adjacent rafters on the back side of the field board to lay it on the top surface of the ceiling board. A technique has been developed that presses down the end of a rare heat insulating material and secures a ventilation space for ventilation in a hut space (for example, see Patent Document 1).

  By the way, in recent years, there is a demand for setting the ceiling height as high as possible in order to obtain a feeling of opening in the indoor space.

  However, in a case where the ceiling plate is simply raised to ensure the ceiling height, a ventilation spacer made of cardboard or the like as in Patent Document 1 is pressed by a heat insulating material laid on the upper surface of the ceiling plate, There was a possibility that the ventilation space would be blocked.

  On the other hand, when the heat insulating material laid on the upper surface of the ceiling plate is made thin so as not to press the ventilation spacer, the heat insulating effect may be reduced.

  In view of the above problems, there has been a demand for the development of a ventilation spacer that prevents the ventilation space from being blocked by the heat insulating material on the top surface of the ceiling plate even if the ceiling height is set as high as possible. .

  The problem of the present invention is that it is possible to secure a ventilation path even when the ceiling height is set high, to ventilate the roof without stagnation, and to efficiently prevent heat from entering the room. It aims at providing the roof structure provided with the heat insulating material and the heat insulating material.

The present invention is a plate-shaped heat shield main body 2 attached to the back side of the roof 10 of the base plate 10a of the roof 10, and the back side of the roof 10 of the base plate 10a of the roof 10 in succession to the heat shield main body 2. In the heat shield material 1 provided with the eaves side heat shield material 3 attached to the eaves side heat shield material 3, the eaves side heat shield material 3 is formed such that its thickness H2 is larger than the thickness H1 of the heat shield material body. By providing a surface layer portion 4 having a height from the back surface of the base plate 10a of the roof 10 higher than the surface of the heat shield main body 2, the surface layer portion 4 has a ridge side from the eave side of the roof. The eaves-side heat shield 3 is positioned above the outer wall panel 11 of the building frame and above the edge of the ceiling heat insulating material 12b adjacent thereto. It is characterized by being installed .

According to the present invention, the eaves-end side heat shield 3 is formed such that its thickness H2 is larger than the thickness H1 of the heat shield main body 2, whereby the surface of the heat shield main body 2 is formed. The roof 10 is provided with a surface layer portion 4 having a high height from the back surface of the base plate 10a of the roof 10, and an air passage 5 penetrating from the eave side to the ridge side of the roof 10 is formed in the surface layer portion 4. Therefore, the ventilation path 5 is not blocked by the heat shield body 2 and, unlike the conventional case, the ceiling height is set high so that the heat insulating material on the upper surface of the ceiling plate is pressed. However, since the air passage 5 can be secured without being blocked, the heat of the roof 10 can be dissipated by allowing the air to pass through the air passage 5 and ventilating without stagnation. Synergistic effect with the heat shield effect of the material body 2 and the eaves side heat shield 3 itself Therefore, it is possible to prevent efficiently heat ingress into the room B1.

  According to the heat shield material of the present invention, the eaves side heat shield material of the heat shield material is formed so that the thickness thereof is larger than the thickness of the heat shield material body of the heat shield material. It has a surface layer part whose height from the back side of the roof base plate is higher than the surface of the heat shield body, and an air passage that penetrates from the eave side of the roof toward the ridge side is formed in this surface layer part. Therefore, the air passage is not blocked by the main body of the heat shield material, and unlike the conventional case, even if the ceiling plate is set to a high ceiling and pressed by the heat insulating material on the top surface of the ceiling plate, Since the air passage can be secured without being blocked, the heat of the roof can be dissipated by allowing air to pass through the air passage and ventilating without any delay, and the heat shield main body and the eaves side shield. The synergistic effect with the thermal insulation effect of the thermal material itself helps to enter the heat into the room. It is possible to prevent well.

  Moreover, according to the roof structure provided with such a heat shielding material, the heat shielding effect of the entire back surface of the field board can be improved, and the heat radiation effect of the entire roof by the eaves side heat shielding material can be improved. In addition, the synergistic effect of the heat shielding effect and the heat dissipation effect can efficiently prevent heat from entering the room in the entire roof.
