Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a summer/winter slope switching type overhang roof that allows solar radiation conditions to be optimally controlled according to seasonal changes.

In conventional buildings, solar radiation is controlled by selecting the shape and orientation of the building, selecting the color and material of the roof and walls, installing eaves, eaves, sunscreens, etc., and selecting the shape, location, and orientation of openings such as windows. This has been achieved through methods and forms such as using the environment around the building, such as trees, but if it is attempted to obtain solar radiation conditions suitable for both summer and winter in the same building, installation costs, installation location, etc. This resulted in a two-point investment, which was extremely uneconomical.

Also, summer and winter use must be set so that they perform contradictory functions regarding solar radiation conditions.
It is difficult to make settings that satisfy both conditions at the same time, which ultimately leads to a decrease in the overall efficiency of sight use, and it is not possible to control the use of natural conditions to the fullest in both summer and winter.

In view of these drawbacks, the present invention consists of the roof of the main body of the building as a mountain-shaped roof structure that slopes in a mountain-like direction in the north-south direction, and an opening is formed at the top of the mountain-shaped structure that extends in both directions of inclination. A flat roof plate is supported on the upper part of the small mountain roof so that it can swing freely around a rotating shaft arranged in the direction of the top ridgeline of the mountain roof structure. An embodiment of the present invention will be described below based on the drawings, in an attempt to solve the above-mentioned drawbacks by providing a summer/winter slope switching type overhang roof in which the opening surface can be selectively opened and closed.1 is the main body of the building, the roof part 2 of which is composed of a mountain-shaped roof structure 3 that slopes in the shape of a mountain in the north-south direction, and the central part of the top of the mountain-shaped structure 3 has an opening that extends across both the north and south slope directions. Openings formed in the north and south directions by cutting out the portion 4 constitute a south opening surface 5 and a north opening surface 6.

Reference numeral 7 denotes a roof plate, which is made of a flat plate having a sufficient area to cover the opening 4 and whose surface is made of a material such as stainless steel that has a high reflectance of sunlight. A rotary shaft 8 disposed in the direction of the top ridgeline of the roof frame 3 is swingably supported via a bearing 9, and the swinging of the roof plate 7 opens the south opening surface 5 and the north opening surface 6 of the opening 4. It is configured to open and close selectively.

Reference numeral 10 designates a small overhang roof for fixing the roof shingle 7 in either swinging state, and is made of a wedge-shaped frame interposed between the lower surface of the roof shingle 7 and the upper surface of the chevron roof structure 3. , the over-roof roof assembly 10 is tightened by a tightening member 11 against a bracket 12 attached to the rotating shaft 8, so that the roof plate 7 can be tightened.
A roof plate 7 is fixed by intervening between the roof roof assembly 3 and the roof assembly 3, and a skylight 13 is attached to the front of the roof assembly 10 so as to be openable and closable.

Reference numeral 14 denotes a heat insulating panel 14 made of a plate-like member having heat insulating properties, and is configured to be slidably attached to the south opening surface 5 from the south lower surface of the mountain hut assembly 3 to open and close the south opening surface 5. ing.

The north wall 15 of the building body 1 is made of a material with a large heat capacity, such as a thick concrete wall without openings, while the south wall 16 has side windows 17 that can be opened and closed.
is installed.

18 is a solar heat collector installed on the upper part of the roof part 2, and the solar heat collector 18 is connected to the upper end of a support 19 whose lower end is rotatably supported on the north end of the building body 1. The north end of the solar heat collector 18 is rotatably pivoted, and the south end of the solar heat collector 18 is rotatably pivoted to the north end of the roof plate 7. When the roof plate 7 is in a state where the north opening surface 6 is opened, the solar heat collector 18 is connected to the roof plate 7.
The length and mounting position of the pillars 19 are determined so that the pillars 19 are placed on an extension line of the inclination angle of It is set.

Next, to explain the operation of the summer/winter slope switching type overhang roof according to the present invention, in the summer season, the roof plate 7 is tilted so that the north opening surface 6 is open, as shown in FIG. A small roof 10 is interposed on the 6 side to fix the roof board 7.

In such a state, in the summer, the solar radiation angle is high, so the surface of the roof board 7 reflects the sunlight, blocking direct sunlight from entering the room, and daylighting into the room is through the skylight 13 attached to the small roof 10. This results in a uniform illuminance distribution.

Regarding ventilation in the room, by opening both the skylight 13 and the side window 17 attached to the south wall 16 as shown in Figure 5, natural ventilation in the room is promoted by ventilation from the south, which is common in summer. be done.

Next, in the middle period from summer to winter, the small roof 10 is removed, the roof board 7 is swung and reversed to the opposite slope, and the roof board assembly 10 is intervened on the south opening surface 5 side. As shown in Figure 6, in the winter, the angle of sunlight is low, so light enters the room through the skylight 13 and from the north wall 15 at the back of the north side.
Direct sunlight enters from the side window 17 of the south wall 16, providing uniform illuminance and heating the room.Furthermore, the north wall 15, which has a large heat capacity, absorbs direct sunlight during the day. is efficiently stored.

Also, at night, the heating effect is maintained by the radiant heat from the north wall 15 that has been stored during the day, and as shown in FIG. By sliding it toward the surface 5 side, the south opening surface 5 is closed and heat radiation from the skylight 13 is prevented.

In addition, when the solar heat collector 18 is used together, in the summer season, as shown in FIG. In the winter, as shown in FIG. 9, the solar heat collector 18 is moved in a direction approximately perpendicular to the low-angle solar radiation direction in conjunction with the adjustment of the roof plate 7. They are arranged so as to face each other, and are set so that the amount of solar radiation received is large, and the light reflected from the surface of the roof board 7 is also adjusted to be able to be used effectively.

In short, in the present invention, the roof 2 of the building body 1 is composed of a mountain-shaped roof assembly 3 that slopes in the north-south direction, and an opening 4 is formed at the top of the mountain-shaped roof assembly 3 extending in both directions of inclination. Formation, Yamagata Koyagumi 3
A flat roof plate 7 is swingably supported on the upper part of the roof frame 7 with a rotating shaft 8 disposed in the direction of the top ridgeline of the mountain shed 3 as a fulcrum. , the north opening surface 9 can be selectively opened and closed, and the solar irradiation conditions can be adjusted simply by adjusting the swing of the roof plate 7 and changing the inclination angle of the roof plate 7 in summer and winter. The roof shingles 7
The operation of switching the inclination angle of the roof plate 7
This can be easily done by adjusting the weight of the water supply to the solar heat collector 18 that is installed separately on the roof plate 7 by balancing it on the left and right sides. Since light can be let in from the roof part 2 through 6, it is possible to maintain a uniform illuminance distribution throughout the room, and in the summer, the room can be effectively ventilated by using the north opening surface 6 as a ventilation hole. The practical effects of this, such as being able to maximize the use and control of natural conditions in both summer and winter, are enormous.
