Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention provides an insulating roof that allows ventilation by arranging hollow panels.

(Prior technology) Hollow members are placed on roof members to allow ventilation inside, and hot air that accumulates on the roof surface on days with intense sunlight such as midsummer is removed to the outside of the roof member by the action of the upward flow of warm air. Techniques for improving the heat insulation effect of roof surfaces are known.

However, since this technology aims to create an upward flow of hot air retained on the roof surface, upward flow is not induced until a certain temperature difference occurs, and although it is effective to some extent, its efficiency is There were limitations in terms of

(Problems to be Solved by the Invention) Therefore, the present invention improves the heat dissipation effect due to the above-mentioned upward airflow, and further utilizes the suction effect of the wind blown against the M root soil surface, and is effective against wind in any direction. It has been devised so that it can be demonstrated effectively.

[Structure of the Invention] (Examples) Hereinafter, the present invention will be described in detail based on the drawings of the examples.
In Fig. 1, 2 is the upper surface member of the roof panel l made of wood wool board, wood chip board, Cerakola board, glass pode, etc., for example, 25 mm thick, 4550 x 1820 mm in length and width.
The surface of wooden wool is compressed with cement glue.

Further, 3 is a similar panel material, but its width is formed to be slightly longer than that of the upper surface member 2 in order to support a connecting member to be described later.

Then, a certain gap (10 mm to 40 m) should be maintained between both panel materials.
m), fix the oblock 4 with a core formed in the shape of a right triangle at the four corners and several places on the left and right sides of the panel material, and make it hollow and open in the vertical and horizontal directions of the panel material to allow ventilation. The structure should be possible.

A reinforcing part 6a having a substantially square cross section and arranged back-to-back with the core block 4 on the side surface in the longitudinal direction is provided on the joining surface of the upper surface member 2 and the lower surface member 3 in the left-right direction, and an opening 6b between ea. A presser metal fitting 6 having a hole therein is arranged. This presser metal fitting 6 is also a necessary member for tightening the roof surface material to the steel structure with bolts or the like.

Further, the exhaust section 7 refers to a ridge having a frontage section, which is usually called a door ridge or a box ridge.

Note that it is desirable to adhere foaming polyethylene film 2a to the outer surface of the upper surface member 2 to prevent condensation due to temperature differences.

(Function) When the roof of the present invention is installed on buildings such as houses and factories, the first
As shown in the figure, since it is hollow, direct sunlight hits the roof surface and causes the temperature to rise, and the hot air creates an upward current, which is discharged from the upper exhaust section 7, exerting a cooling effect. that time,
Since each end of the hollow panel 1 has an opening, ventilation is extremely good.

Next, a weak or strong wind is usually blowing above the roof, and when this wind passes near the exhaust device, it sucks the air in the frontage of the exhaust device, producing an ejecting effect. In this case, the roof of the present invention is a combination of a hollow panel 1 that allows ventilation in the vertical and horizontal directions, and a grate 6 in which a frontage part 6b is bored between the reinforcing parts 6a and 6a. Since ventilation is possible from both the left and right sides, as shown in Figure 3, no matter which direction the wind blows from, convection will occur from all directions within the panel and warm air can be collected, which is then discharged.
It can exhibit a cooling effect that is not found in the above effects and double the same effect.

In terms of construction, it is only necessary to join both panels and the holding metal fittings 6 and fix them to the pillars on the roof surface, and the construction can be carried out with simple work.

[Effects of the Invention] As described above, the present invention doubles the roof surface cooling by utilizing the upper airflow to induce an eject effect, which previously relied only on the rising airflow of warm air and had an unsatisfactory cooling effect. For example, when a cooler is used in a factory or the like during the summer, it can be made effective instead of the one that conventionally had little cooling effect due to direct heat.

In addition, the construction can be carried out by simply tightening the hollow panel l and the presser fitting 6 with bolts or the like, and the construction work can be carried out efficiently.
