Description

The present invention relates to a roof apparatus having a function of circulating outside air to the back side of a roof plate material according to a change in outside air temperature to ventilate.

Conventionally, roofing of ordinary houses has been done using tiles or slate boards, and large roofs such as factories and gymnasiums using slate tiles and tin boards, but nowadays they are made of lightweight and durable metal. Roofing is performed using a roof plate made of a galvanized plate or a colored iron plate.

A roof gutter lays a ground plate on a rafter attached to a beam that is a roof structure material, and a thermal insulation sheet or a prevention sheet is stretched on the field plate, and a plurality of roof plate materials are attached to the upper surface of the sheet. It is connected while being fixed in order from the eave side to the ridge direction.

The roofing board made of metal plate material is thin, so when roofing is performed, it is easy for the roofing board to be deformed due to its weight when the operator gets on the roof for roofing work or inspection. Is directly fixed to the base plate. Therefore, it was not possible to perform roofing by providing an air layer between the roof board and the field board. Therefore, the heated high-temperature air accumulated on the back side of the roofing board in the high temperature period such as summer is transmitted to the indoor side, so that an air conditioner is inevitably necessary in the room.

In addition, there is a roof device that circulates outside air by providing a gap between the field board and the roof board, but its structure forms a double field board and a gap between the lower field board and the upper field board. It is known that a heat sink is provided and air is circulated to prevent heat from being accumulated on the back side of the roof (for example, see Patent Document 1).

When the ridge side of the roof plate 2a is lowered in the direction of the base plate T after being locked inside the lock receiving portion 39, the horizontal portion 7a is joined and locked to the upper surface of the eaves tip receiving portion 40.

The ridge-side connecting portion 10a of the roof plate 2a is hooked between the insertion portion 14a provided on the ridge side and the ridge receiving portion 30 of the footrest hanging piece 25 and inside the upright portion 29 of the footrest hanging piece 25. Then, the base 28 is fixed to the base plate T after matching the outside of the vertical portion 15a of the ridge-side connecting portion 10a. The roof plate 2a is fixed to the base plate T with a leg height hanging piece 25 having legs 27, so that the lower side of the roof side of the roof plate 2 does not directly contact the base plate and the roof plate 2 and the base plate T. A space X can be provided between the base plate T and fixed.

After fixing the ridge side connecting portion 10a of the roof material 2a as described above, the insertion portion 8b of the eaves side engaging portion 5b of the next roof plate 2b is connected to the roof material 2a on the ridge side. The roof plate 2b is inserted in the engagement recess 13a provided in the ridge side connecting portion 10a and the roof plate 2b is lowered in the direction of the base plate T, and the lower surface of the horizontal portion 7b and the upper surface of the horizontal portion 12a of the ridge side connecting portion 10a of the roof plate 2a. It is mounted on and locked.

Furthermore, the foot height hanger piece 25 is connected to the ridge side connecting portion 10b of the roof plate 2b as described above, and is fixedly connected to the field board T. By repeating this operation, the roof material 2 is connected in order in the direction of the ventilation building 16 to perform roofing. As shown in FIG. 10, the ridge portion locks the ridge-side connecting portion 10 e of the roof plate 2 e to the ridge stopper piece L, and this ridge stopper piece L is placed inside the ridge stopper portion 23 of the ridge fixing piece 21.

Since it is removed from the air vent 38 and closed, it has a heat insulating effect that prevents the entry of outside air and can accumulate warm air in the space X between the roof plate 2 and the base plate T.

The second eaves edge plate frame 61 is slidably attached to the lower surface of the outside air intake portion 65, and the ventilation device 80 is attached to one end of the outside air intake portion 65 to connect the movable shaft and the second slide plate 70. It can be attached by a simple operation of simply connecting the pieces 73, and the number of parts is small, so that the cost is low and economical. In addition, when the attic becomes hot during summer or the like, when the displacement spring 85 attached to the ventilator 80 reaches a predetermined outside air temperature (17 degrees Celsius or higher), the elastic force of the displacement spring 85 causes the elastic spring 86 to move. elongation against the spring force, the movable shaft 82 and the second sliding plate 70 made to match the sliding is allowed vents 71 and vent 66a opens.

When the outside air temperature reaches a predetermined temperature (7 degrees Celsius or less), the displacement spring 85 of the ventilation device 80 contracts, and the elastic force of the elastic spring 86 causes the movable shaft 82 and the second slide plate 70 to move through the partition plate 83. The vent 66a is closed by sliding in the direction of the displacement spring 85.

In the roof apparatus in which the third ventilator 103 is attached to the second eaves edge plate frame 61, when the opening / closing plate 104 formed of the shape memory alloy material senses a predetermined temperature, it deforms in an upward direction and thereby vents 66b. , And the outside air enters the attic side and circulates, so that the temperature on the back side of the roofing board can be lowered by 10 degrees or more as compared with the case where it is formed of a normal roofing board material.

Therefore, it is very economical because the set temperature of the air conditioner installed in the room can be lowered and the power consumption can be suppressed because the usage time is short. If the outside temperature such as in winter drops below 7 degrees, the roof to prevent outside air ingress by opening and closing plate 104 mounted on the third ventilator 10 3 is closed the vent back to the original shape In the space part X of the board 2 and the field board T, it has the heat insulation effect which can accumulate warm air.

The third ventilator 103 attached to the second eaves edge plate frame 61 can be attached to the vent 66b of the outside air intake portion 65 by a simple operation of fixing the open / close plate 104 with the fixture 105, respectively. Since the number is small, the cost is low and economical.
