Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a roof structural material made of metal plates having functions such as natural ventilation and smoke exhaust.

[Conventional technology]

Conventionally, roof structural materials (roofing materials) for roofing buildings have been made of various materials such as tiles, metal plates, and asbestos plates.

Furthermore, ventilation devices are installed on the roofs of warehouses, factories, gymnasiums, etc. to ventilate indoor spaces, and smoke exhaust devices are provided to exhaust smoke generated in the event of a fire to the outdoors.

[Problem that the invention seeks to solve]

Conventional roof structural materials have a structure that completely seals the roof without any gaps and completely prevents rainwater from entering, and no technology corresponding to the present invention has been provided to date.

In addition, there are two types of ventilation systems mentioned above: natural ventilation and forced ventilation, but both have complex mechanisms to prevent wind and rain from flowing back into the building. Since it is necessary to install multiple ventilation devices, it is necessary to reinforce the roof base structure, which requires a large amount of cost to install ventilation devices.

Furthermore, smoke evacuation devices include those that are formed on a wall like a window, and those that are installed on the roof of a rooftop building. It was impossible to use it during rain or rain, and its range of use was limited.

[Means for solving problems]

The present invention has been developed in view of the above-mentioned conventional hermetic structure using roof tiles and metal roof structures, and also in view of the various problems of roof structures that require the installation of ventilation and smoke evacuation devices. It is an object of the present invention to provide a roof structural material that has the following functions and can prevent wind and rain from entering indoors.

In order to achieve this object, the present invention has vertical plates 4.5 installed above and below an inclined plate 3 formed at the center in the length direction of a strip-shaped metal plate, and a shielding plate 6 is provided inwardly on the upper vertical plate 4. , A plurality of shielding members 2 each having a guide plate 7 connected to the outer side are arranged on the lower vertical plate 5 in a horizontally long manner so that the upper and lower sides of the adjacent shielding members 2 are overlapped with a space in between. Set up i
The screen is characterized by having a screen formed on the screen, and the shielding surfaces are placed symmetrically with a space provided on both sides.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 indicates a roof structural material according to the present invention, which is constructed by combining a plurality of metal shielding members 2.

The shielding member 2 is formed by bending a long strip-shaped metal plate along the crosswise direction.

That is, an inclined plate 3 is formed at the center in the length direction of one strip-shaped metal plate, and vertical plates 4 and 5 are bent and connected to the upper and lower sides of the inclined plate (3). The plate 4 is provided with a shielding plate 6 extending inwardly, and the lower vertical plate 5 is provided with a guide plate 7 extending outwardly in an inclined manner.

This shielding member 2 is installed on both sides and is arranged horizontally by fixing the lower vertical plate 5 to the support column 8 using fasteners (not shown) such as screws and bolts.

Similarly, a plurality of shielding members 2 are arranged and fixed downward along the support 8, but in this case, the positional relationship between the vertically adjacent shielding members 2 is that of the shielding member 2 located above. The lower vertical plate 5 and the upper vertical plate 4 of the shielding member 2 located below overlap with each other with a space between them, and the plurality of shielding members 2 form a shielding surface as if it were one surface.

The shielding members 2 are fixed at the same height on both sides of the support column 8, so that a suitable space is provided and shielding surfaces of the same structure are formed symmetrically.

Note that the number of pillars 8 is not limited to two, and depending on the length of the shielding member 2, it may also be installed in the middle part for reinforcement.

The roof structural material 1 having two shielding surfaces formed by the plurality of shielding members 2 as described above can be manufactured in standard products of various sizes and used by connecting them vertically and horizontally.

In the above explanation, 1. Each shielding member 2 is installed at the same height on both sides of the support column 8, but as described above, the lower vertical plate 5 of the upper shielding member 2 and the lower shielding member 2
If the upper vertical plate 4 is in a stacked state with a space between them, the shielding members 2 on both sides of the support column 3 should be installed at different heights and alternately above and below, as shown in Fig. 4. It's okay.

Next, an example of use of the roof structural material 1 having the above structure will be explained.

FIGS. 5 and 6 show a case where a known roof 91 and ridge structure 10 are constructed.

An opening 11 is formed in the roughly closed roof 9, and a draining plate 12 is installed so as to surround this opening 11.

A pair of roof structural members 1 are installed in an inclined manner from both sides of the opening 110, connect the ff1 parts of both roof structural members 1, and stably fix the lower part to the roof 9 (-2C), making the overall triangular ridge structure 10 It's Toshide.

Both sides of this ridge structure IO are sealed by appropriately structured sealing devices 13.
, and take care of the rain.

Note that 14 in the figure is an exterior wire plate installed at the top of the ridge structure 10.

In the ridge structure 10 having the above configuration, a space is formed between each of the shielding members 2, and a space is also formed between the shielding surfaces of the eight pillars, so that indoor and outdoor air can circulate. Therefore, indoor ventilation occurs naturally, and the smoke generated indoors, which has a lower specific gravity than air, rises and is naturally discharged from the space of the roof structure material 2.

When it rains, as shown by the arrow A in Figure 7, rainwater infiltrates from the space of each shielding member 2 on the outside, but rainwater travels in a step-like manner through the inner surface of each shielding member 2 that constitutes the shielding surface on the indoor side. , rainwater will flow away from the lowermost shielding member 2 onto the roof 9, preventing rainwater from entering or falling indoors.

In addition, as shown by the arrow B in FIG. 5, the wind is guided upward along the outer surface of the shielding member 2 on one side of the ridge structure 0, and a negative pressure phenomenon is generated on the opposite side of the ridge structure 10. of air will be sucked outside, creating a condition of forced ventilation.

The above explanation is for the case where the ridge structure 10 is constructed on a conventionally known roof 9''L, but it goes without saying that the roof structure material of the present invention may be used as a normal roofing.

[Effects of the Invention] As explained above, the roof structure material of the present invention has a single shielding member 2 arranged in a horizontally elongated manner, and a plurality of shielding members 2 are overlapped to form a space, and a plurality of shielding members 2 are installed to form a shielding surface. By forming this shielding surface and installing it symmetrically with space on both sides,
When used as a roof material 2, a circulation space is formed without sealing the roof, so it has indoor ventilation and smoke exhaust functions.

Therefore, by constructing the roof of a factory, warehouse, gymnasium, etc. using the roof structure of the present invention, or by constructing a part of the roof in the form of a rooftop roof, there is no need to install ventilation equipment, smoke exhaust equipment, etc. .

In addition, by installing the shielding surface composed of a plurality of shielding members 2 symmetrically on both sides, even if rainwater infiltrates from the space of the outer (outdoor side) shielding surface, the inner (indoor side) shielding Rainwater flows away along the inner surface of the inner shielding surface, preventing it from penetrating indoors.
