Abstract

PURPOSE:To prevent the penetration of heat from a roof of a precision shop or the like in particular by allowing air to flow spontaneously or forcibly in a box-shaped thick board having a penetration hole. CONSTITUTION:A board material 1 having a square-shaped or other-shaped penetration hole whose one side is possibly at least 2cm, is mounted to a roof. When the board is mounted, an exposed penetration hole 11, which is larger than 10cm, is installed to the lower part of a ridge board 8. When the surface layer of the board is heated with solar energy, natural energy forces the air to flow upward from the lower end by way of the penetration hole 2. This air is further discharged outside from the exposed penetration hole 11 and an exhaust clearance 9. When the air is not exhausted to a satisfactory extent due to a small roof slope, a forcible exhaust fan is used. A projected frame or the like is installed to the end of the board material 1 so as to prevent the penetration of rainy water from the clearance of the board 1. When the weather is cold, the penetration hole 2 is shut down, thereby preventing the in-flow of cooled open air.

2. Description of the Related Art Conventionally, it has not been used as a roof for controlling the temperature of a room, and a heat insulating material is attached under the roof material, or a ceiling is provided under the roof, and air between them is forcibly discharged. Method was taken.

[0003]

Recently, factories have come to adjust temperature even in ordinary factories. In addition, since many factories such as a carrier are installed in the ceiling of the factory, it is often impossible to construct the ceiling. Also, even if a ceiling can be made in a semiconductor or other precision industry factory, the heat entering the room through the roof is enormous. Especially in the tropics, the problem was how to prevent heat from entering from the roof.

SUMMARY OF THE INVENTION In the present invention, air is circulated in the roof body in order to complete the circulation of the air in the roof body and help maintain the room temperature at a desired temperature at all times. To do.

In order to achieve the above object, a hollow plate body (FIGS. 1 and 2) is made as a roof member by extrusion molding of cement, metal or the like, or by another method. As shown in FIG. 1, this has an elongated box shape and a large number of through holes (2), and the wall thickness is as thin as possible. On the other side, there is also a cross rail that constitutes the skeleton of the roof, commonly known as a purlin (3) for hanging on the purlin (3) for hooking on the purlin (10). Also, the number of ridges in the main store is not always 1.
There is no need for a body structure, it may be retrofitted, a material different from that of the roof member may be used, and the shape may be an angle.

In the process of manufacturing this roof, first, the tip of the exposed portion of the A member (FIG. 1) with the exposed through hole (11) facing upward is brought into close contact with the purlin (13) at the top, and the purlin (10). Mount in a horizontal row on top. Next, the A member and its through hole are accurately connected so that the B member is attached to the roof portion up to the eaves.

As an example of the mounting method, the purlin hanging ridges (3) of (Claim 3) of the present invention are used to securely fix the purlin to the purlin by a method such as nailing, brazing or welding. Alternatively, the side surface of the member may be machined in the conventional construction method, such as tempering and the actual fruit, and the side surface of the member may be used for mounting on the purlin. If the joint portion with the adjacent plate is made of (claims 4 and 5), the effect will be greater, but in any case, a waterproofing agent is used to prevent water leakage.

The ridge plate (8) is an elongated thin plate made of metal, plastic or the like. Both sides are under the exposed part, a few c
It has a width that covers up to m and can be vertically moved to be attached to a purlin. This is moved up and down to open and close the exposed portion to optimally control the air flow in the through hole. In the severe cold of winter,
It is possible to seal the through hole to block the flow of air and fill the through hole with air heated by solar heat. Also, in hot areas, use the one with the ridge board fixed open. Alternatively, the ridge board may not be used.

[0009]

[Operation and effect] Although the roof currently used blocks sunlight, it cannot prevent the heat and raises the indoor temperature. In some cases, heat insulating material is attached to the back side,
It only slows down the penetration of heat. Since the heat insulating roof of the present invention is stretched by the method as described above, air flows in from the lower end side of the roof and the eaves, and even when the surface layer is warmed by solar heat, the warmed air flows upward, It is discharged from the exposed through hole (11) near the purlin through the exhaust gap (9) under the purlin, and cold air constantly fills the through hole to keep the lower surface of the main roof at a low temperature. Moreover, the air is discharged naturally and does not require any artificial energy. In order to prevent the indoor temperature from dropping due to the influence of the roof during cold weather, it is possible to pull down the ridge board to seal the through hole, stop the air flow in the through hole, and shut off the cold temperature of the outside air.

(Claims 4 and 5) are intended to prevent rainwater from leaking when it is stretched, and cover the gap with the adjacent roofing material with a protruding brim, or use a metal fitting to prevent the inflow of rainwater. It has a great effect to prevent it.

Further, (Claim 6) has a structure provided with the forced exhaust device of (Claim 6) in the case where the slope of the roof is small and exhaust is not performed sufficiently. In this structure, a cavity (17) through which air flows horizontally near the top of the roof is composed of a roof plate, a member, and a thin plate below the member and in close contact with the member, and a through hole is opened in this cavity. Forced exhaust fans are provided at both ends of the cavity and at appropriate positions to exhaust electricity or wind.

In order to apply the structure of the heat insulating roof to the structure of the outer wall, the member of the present invention is used to expose the through holes at the upper end and the lower end, and the air flowing in from the lower end exposing port is exposed at the upper end exposing port. To spill from. The through hole may not be exposed at the upper end, and a cap tree may be attached (to prevent rainwater from entering) at a distance from the upper end of the plate body so that the air may flow out from the upper end of the plate body to serve as an air outlet.
