Description

  The present invention relates to a monitor roof that is attached to the roof portion of various buildings such as factories, gymnasiums, markets, barns, and incinerators, and that exhibits not only the original ventilation function but also the daylighting function, and the reflected light path inside the monitor roof. It relates to a forming method.

  The monitor roof is a small roof (see FIG. 4) having an elongated box shape, for example, set on the top (ridge) of the building roof.

  In this specification, the longitudinal direction of the box shape is referred to as “vertical”, and the direction orthogonal to the longitudinal direction is referred to as “horizontal”. 1 to 3 and FIG. 5 each show a cross-sectional state in the lateral direction. The space between the lower opening and the upper opening of the monitor roof is called “monitor space”.

  The inside of the building communicates with the outside of the building via the monitor roof, and the air inside the building that has risen in temperature is exhausted from the monitor roof to the outside of the building.

  Here, it is desirable not only to ventilate the interior of the building, but also to provide a monitor roof that can actively and efficiently incorporate natural light outside the building into the interior of the building, and formation of a reflected light path there, and the present invention meets such a demand.

For example, the monitor roof
・ Upper opening as an interface with external space ・ Lower opening as an interface with building interior ・ Monitor space demarcating section from the upper opening to the lower opening (outer wall etc.)
-It consists of an inner roof part (with respect to the said lower opening part) etc. which is set above a lower opening part.

Conventionally, as a monitor roof with components to actively take natural light outside the building into the building interior,
(11) Monitor roof provided with daylighting windows on both side walls of the monitor space demarcating section (see Patent Document 1 below)
(12) Monitor roof with inner roof made of transparent reinforced synthetic resin or tempered glass (see Patent Document 2 below)
and so on.

  Both of these ideas are designed to introduce natural light outside the building as direct light into the lower opening of the monitor roof.

JP-A-5-180476 JP 9-303836 A

  The conventional daylighting method in which such a daylighting operation part such as a window or tempered glass is provided on the monitor roof has a problem that the construction cost is high and the construction work is easily complicated. In particular, when these lighting parts are installed on an existing monitor roof later, this problem becomes prominent.

  Furthermore, there is a problem that the daylighting unit made of glass is easily deteriorated due to the influence of the outside air or the heat of the building (factory).

  Therefore, in the present invention, a non-linear space region (a part of the monitor space) extending from the upper opening of the monitor roof to the lower opening through the peripheral portion of the inner roof is used as the lower opening for incident natural light in the upper opening. It is intended to be able to realize natural lighting from the monitor roof to the building with low cost and simple construction.

  That is, for example, a monitor space inner surface provided continuously between the upper opening and the lower opening, and a mirror surface in which a specular reflector, for example, a metal sheet-like specular reflector is attached to the lower surface of the inner roof The purpose is to ensure natural lighting from the monitor roof to the building by providing a reflecting part and introducing the incident natural light from the upper opening to the lower opening by the specular reflection at the specular reflecting part. .

  In addition, the diffused light with the diffuse reflection part on the upper surface of the inner roof part located below the upper opening part (= above the lower opening part), for example, a metal sheet-like diffuse reflecting material, is first incident natural light from the upper opening part. An object of the present invention is to improve the efficiency of introducing natural light from the monitor roof into the building by reflecting the diffusely reflected light from the reflected portion to the mirror space inner surface portion or the lower surface portion of the inner roof portion.

  It is another object of the present invention to provide a light guide unit that allows natural light that has reached the lower opening from the upper opening to enter the building, thereby further improving the efficiency of introducing natural light from the monitor roof to the building.

The present invention solves the above problems as follows.
(1) In a monitor roof (for example, a monitor roof 5 to be described later) attached to a roof portion of the building (for example, a roof body 1 described later) and exhibiting a ventilation action in the interior of the building,
An upper opening (for example, an upper opening 3 described later) acting as a light receiving port and an upper ventilation port;
A lower opening (for example, a lower opening 1b described later) that is formed in the roof portion of the building and acts as a light emission port and a lower ventilation port;
A monitor space inner surface (for example, an inner surface and a bottom surface 1a of an outer wall 2 described later) extending from the upper opening to the lower opening;
An inner roof portion (for example, an inner roof portion 4 described later) set in a state of being separated from the inner surface portion above the lower opening,
Each of the lower surface part of the inner roof part and the monitor space inner surface part,
A specular reflection part (for example, a specular reflection sheet material 11 described later) is provided.
(2) In (1) above,
A metal sheet-like specular reflector is used as the specular reflector.
(3) In (1) above,
On the upper surface of the inner roof part,
A diffuse reflection portion (for example, a diffuse reflection sheet material 12 described later) is provided.
(4) In (3) above,
A metal sheet-like diffuse reflector is used as the diffuse reflector.
(5) In the above (1) to (4),
A light guide unit (for example, a first-open louver unit 15 described later) is provided for allowing natural light reaching the lower opening from the upper opening to enter the building.
(6) It is attached to the roof of the building and exhibits the ventilation of the interior of the building,
An upper opening that functions as a light receiving port and an upper ventilation port, a lower opening that is formed in the roof portion and functions as a light emission port and a lower ventilation port, and an inner surface of the monitor space extending from the lower opening to the upper opening And an inner roof portion set in a state of being separated from the inner surface portion above the lower opening portion,
In the method of forming the reflected light path inside the monitor roof,
A specular reflection part is set to each of the lower surface part and the inner surface part of the inner roof part.

  The present invention is directed to a monitor roof having the above-described configuration and a method for forming an optical path of the monitor roof.

  As described above, according to the present invention, a non-linear space area (a part of the monitor space) extending from the upper opening of the monitor roof to the lower opening through the periphery of the inner roof is reduced with respect to the incident natural light of the upper opening. Since it is actively used as a regular reflection light path to the lower opening, natural lighting from the monitor roof to the building can be realized at low cost and with simple construction.

  In addition, the diffused light with the diffuse reflection part on the upper surface of the inner roof part located below the upper opening part (= above the lower opening part), for example, a metal sheet-like diffuse reflecting material, is first incident natural light from the upper opening part. Since the diffusely reflected light from the reflection part is specularly reflected from the inner part of the monitor space and the lower part of the inner roof part, the efficiency of natural light introduction from the monitor roof to the building can be improved.

Thus, by first diffusely reflecting the incident light to the upper opening 3,
(21) Parallel incident light is reflected and condensed on the concave surface, preventing accidents such as heat generation and ignition,
(22) Large fluctuations in lighting conditions due to seasons and time zones can be mitigated.

  Moreover, since the light guide part for entering the natural light which reached | attained the lower opening part from the upper opening part into a building is provided, the diffusion range of the light radiated | emitted to a building can be expanded.

2 and 3,
In the natural light entering the upper opening 3 of the monitor roof 5, A does not hit the diffuse reflection sheet material 12 of the inner roof part 4, but the lower opening portion by specular reflection by the specular reflection sheet material 11 exclusively. Incident light introduced into the building from 1b,
B is first diffusely reflected in the diffuse reflection sheet material 12 of the inner roof portion 4 in the natural light entering the upper opening 3 of the monitor roof 5, and then this irregular reflection light is positively reflected by the specular reflection sheet material 11. Incident light introduced into the building from the lower opening 1b by reflection,
Respectively.

Reference numeral 18 denotes a louver provided in the upper opening around the inner roof portion 4 to prevent rainwater from entering the lower opening 1b of the roof body 1.

  FIG. 5 shows that the present invention can be applied to a monitor roof provided with the outer wall portions 16 and 17 in which the specular reflection sheet material 11 and the diffuse reflection sheet material 12 are omitted. Yes. In the case of the monitor roof of FIG. 5, the bottom surface portion 1a (of the roof main body 1) which is a component of the monitor roof 5 of FIGS.

  Here, a mirror surface specification aluminum sheet “MIRO2” (“MIRO” is a registered trademark) manufactured by Alanod (Germany) is used for the specular reflection sheet material 11. Instead of the specular aluminum sheet, a specular stainless steel sheet or a resin sheet subjected to a vacuum metal deposition film treatment of silver or aluminum may be used.

The diffuse reflection sheet material 12 includes:
・ Satin-finished aluminum sheet “MIRO8” manufactured by Alanod, Germany (“MIRO” is a registered trademark)
・ Rough surface specification aluminum sheet "MIRO9"("MIRO" is a registered trademark) manufactured by Alanod, Germany
・ Furukawa Sky Co., Ltd. diffuse reflection aluminum sheet "Fuscoat Crystal (registered trademark)"
・ Other materials such as white (white, ivory, cream, yellow, etc.) with a highly reflective diffusion surface are used.

  The first feature of the illustrated monitor roof is that the lower opening 1b is opened from the upper opening 3 by specular reflection by the specular reflection sheet material 11, that is, without requiring irregular reflection by the diffuse reflection sheet material 12. That is, a regular reflection optical path of incident light A introduced into the building is formed.

  The regular reflection optical path is formed on the inner surface of the monitor space (= the inner surface of the outer wall 2 + the bottom surface 1a) extending from the upper opening 3 to the lower opening 1b and the upper surface of the inner roof 4. This is a specular reflection sheet material 11.

  That is, the monitor space from the upper opening 3 to the lower opening 1b is focused on the spatial arrangement relationship between the inner surface of the monitor space and the upper opening 3, the inner roof 4 and the lower opening 1b. In FIG. 5, the incident light to the upper opening is positively reflected and led to the lower opening.

  In particular, in the case of a monitor roof in which the upper opening 3 extends to the outside of the inner roof portion 4 as shown in FIG. 5 (b), the natural reflection into the building by only the specular reflection of the specular reflection sheet 11 is performed. Daylighting is effective.

  The second feature is that the diffuse reflection sheet material 12 is attached to the upper surface side of the inner roof portion 4. Here, the natural light incident on the upper opening 3 is diffusely reflected by the diffuse reflection sheet material 12 like the incident light B first. Subsequently, the diffusely reflected light enters the building from the lower opening 1b by regular reflection at the specular reflection sheet material 11 similar to the incident light A.

  The third feature is that the first opening louver unit 15 is attached to the lower opening 1b to widen the diffusion range of light emitted from the lower opening 1b into the building.

  The structure of the monitor roof body in a state where the specular reflection sheet material 11, the diffuse reflection sheet material 12, and the front opening louver unit 15 are discarded from the illustrated monitor roof 5 is well known.

  The outer wall portion 2 is attached to the C-type channel 8 (and the column member 7b), and the inner roof portion 4 is attached to the C-type channel 10 (and the beam member 9a).

  The C-shaped channels 8 and 10 are supported by the H-shaped steel 6 through many column members 7 and beam members 9.

  When attaching the specular reflection sheet material 11 and the diffuse reflection sheet material 12, various fixing means such as riveting, screw fixing, and adhesion are used. Further, when attaching the specular reflection sheet material 11 or the diffuse reflection sheet material 12, the sheet material is cut according to the space of the installation target portion.

For example, in a typical rolling mill building with a width of 20 to 40m, a height of 10 to 20m, and a length of 10m or more, mercury lamps or metal halide lamps are installed as lighting lights at intervals of about 10m in 2 to 3 rows. Since mercury lamps are approximately 60,000 lumens / lamp and metal halide lamps are 100,000 lumens / lamp, the amount of radiation is 1020,000 to 1020,000 meters per building length, mercury lamps are 120,000-180,000 lumens, and metal halide lamps are 200,000-300,000 lumens.
On the other hand, the case where a specular reflector and a diffuse reflector as shown in Fig. 1 and Fig. 2 are installed inside the monitor roof (width 8m, height 4m) installed in the rolling mill building is studied and calculated. As a result, it was found that an annual radiation amount of 220,000 lumens can be expected on an average of 8 to 16 o'clock in fine weather per 10 m of the monitor roof. Therefore, a sufficient energy saving effect can be obtained if the radiation amount is used as a light source that changes to a daytime illumination lamp or in combination with an illumination lamp that can be automatically dimmed according to ambient brightness. That is, when the present invention is applied to a building having a width of 20 to 40 m, a height of 10 to 20 m, and a length of 10 m or more, a remarkable effect can be obtained.

It goes without saying that the present invention is not limited to the above embodiment, and may be as follows, for example.
(31) Instead of using the diffuse reflection sheet material 12, the upper surface of the inner roof portion 4 is painted white.
(32) A first aperture louver is used instead of the first opening louver unit 15.
(33) Use both the front louver and the front louver.
(34) The outer wall 2 is provided with a daylighting window, a half mirror, and the like so that incident light from the window is reflected by the specular reflection sheet material 11 and the diffuse reflection sheet material 12.
(35) The specular reflection sheet material 11 is attached to the inner surface of the outer wall portion 2, the lower surface of the inner roof portion 4, the beam 9a, and the like.
(36) The specular reflection sheet material 11 and the diffuse reflection sheet material 12 are attached only to the northern part of the monitor space. For example, when the upper direction of FIG. 1 itself is “north”, the specular reflection sheet is provided only on the substantially upper half of each of the bottom surface portion 1a, the outer wall portion 2, and the inner roof portion 4 (substantially right half when the drawing is viewed horizontally). The material 11 and the diffuse reflection sheet material 12 are attached. Thereby, cost reduction can be achieved.
