  Embodiments of the present invention will be described with reference to the drawings.

  The sunshade structure 10 according to the present embodiment forms a roof portion outside the building opening 31, and as shown in FIG. 1, a pillar member 15, an inclined frame member 14, and a horizontal beam member 20.

  As shown in FIGS. 1 and 2, the column member 15 is erected substantially parallel to the wall surface 30 of the building and substantially perpendicular to the ground surface. The column members 15 are provided in a plurality (four in the present embodiment) at a predetermined interval, and a plurality of horizontal beam members 20 are horizontally arranged between the adjacent column members 15 so as to be blindfolded. 13 is formed. In the present embodiment, the horizontal beam member 20 is attached only to the upper part of the column member 15, and the horizontal beam member 20 is not provided in the lower part near the ground surface. This is to reduce the feeling of blockage when the sunshade structure 10 is viewed from the inside by not providing the crosspiece member 20 at the lower part where the blindfold function is not so required.

  The inclined frame member 14 is a columnar member connected to the upper end of the column member 15, and is inclined so as to approach the wall surface 30 of the building as it goes upward. The upper end of the inclined frame member 14 is fixed to the wall surface 30 of the building. A plurality of (four in the present embodiment) the inclined frame members 14 are provided at predetermined intervals in the same manner as the column members 15, and a plurality of horizontal beam members are horizontally disposed between the adjacent inclined frame members 14. The roof portion is formed by arranging 20.

  The crosspiece member 20 is a hollow louver member, and as shown in FIG. 3, a plurality of members having the same cross-sectional shape are fixed to the column member 15 and the inclined frame member 14 with a constant interval. The crosspiece member 20 has a cross-sectional shape formed in a parallelogram. Specifically, in the cross-sectional shape, the first long side surface 21 and the second long side surface 22 that form the longer opposite side, and the cross-sectional shape The first short side surface 23 and the second short side surface 24 that form the shorter opposite side form a parallelogram.

  The horizontal beam member 20 is fixed to the column member 15 and the inclined frame member 14 using a screw hole 25 provided therein, and the screw hole 25 is attached to the column member 15 and the inclined frame member 14 in advance. By being aligned with the drilled screw holes, the mounting positions for the column member 15 and the inclined frame member 14 are determined. The screw hole 25 is formed on the back side of the first long side surface 21 and the second long side surface 22. The first long side surface 21 is provided closer to the second short side surface 24, and the second long side surface 22 is provided closer to the first short side surface 23.

  By the way, as shown in FIGS. 1-3, the above-mentioned roof part is from the said building opening part 31 rather than the 1st roof part 11 arrange | positioned in the position near the building opening part 31, and this 1st roof part 11. As shown in FIG. And a second roof portion 12 disposed at a distant position. When the first roof portion 11 and the second roof portion 12 are compared, the installation pitch of the horizontal beam member 20 is the same, but the installation angle of the horizontal beam member 20 is different. In this way, the amount of solar radiation is adjusted by changing the installation angle of the crosspiece member 20.

  That is, as shown in FIG. 4A, the cross rail member A of the first roof portion 11 is disposed substantially horizontally. Specifically, the first long side surface 21 and the second long side surface 22 are ground. It is fixed to the inclined frame member 14 so as to be horizontal to the surface. For this reason, the horizontal beam member A of the 1st roof part 11 is attached with the angle with a large projection area per one of the horizontal beam member 20 when it projects from right above. Moreover, as shown in FIG. 3 etc., the horizontal beam member A of the 1st roof part 11 is arrange | positioned so that it may overlap when it projects from right above, and a clearance gap does not arise between the adjacent horizontal beam members A. Are arranged as follows. The horizontal beam member A is attached in such a way that the projected area is large and overlapped so that the solar radiation from above can be blocked, and the sun rises as shown in FIG. Sunlight is effectively shielded in the summer, and a large shade can be formed particularly near the building opening 31.

  In addition, the crosspiece member A of the 1st roof part 11 inclines to the outdoor side as the 1st short side surface 23 and the 2nd short side surface 24 go down, in other words, the 1st short side The surface 23 is inclined in a direction to receive solar radiation. This is because the sunlight is inserted slightly obliquely even in the summer when the sun rises, so that this oblique sunlight is received by the first short side surface 23. In this way, by receiving the oblique solar radiation at the first short side surface 23, the sunlight can be shielded more effectively.

  Moreover, as shown in FIG.4 (b), the crosspiece member B of the 2nd roof part 12 is an inclination frame so that the 1st long side surface 21 and the 2nd long side surface 22 may incline with respect to the ground surface. It is fixed to the member 14. At this time, the horizontal beam member B is inclined so that the outdoor side is higher than the building opening 31 side. Specifically, the first long side surface 21 and the second long side surface 22 are lowered as they go downward. Inclined inward. Thus, compared with the horizontal beam member A of the 1st roof part 11, the horizontal beam member B of the 2nd roof part 12 has the 1st long side surface 21 and the 2nd long side surface 22 with respect to a solar radiation direction. It is arranged so as to be as parallel as possible. In this embodiment, the inclination angle at this time is 25.35 ° with reference to the incident angle of solar radiation at the time of winter solstice in Tokyo. By providing the horizontal beam member 20 in an inclined manner in this way, the projected area per one of the horizontal beam member 20 when projected from directly above is reduced and the solar radiation is not blocked. For this reason, sunlight can be taken in from between the crosspiece members 20, and as shown in FIG. 6, the sunlight can be taken in effectively in winter when the sun gets low, and the sunlight can be taken into the building. Is formed.

  In addition, as shown in FIG.4 (c), the 1st long side surface 21 and the 2nd long side surface 22 are also the horizontal beam member C of the blindfold part 13 similarly to the horizontal beam member B of the 2nd roof part 12. As shown in FIG. It is being fixed to the inclination frame member 14 so that it may incline with respect to the ground surface. In the present embodiment, the inclination angle is substantially the same as the horizontal beam member B of the second roof portion 12 (specifically, the inclination angle is smaller than the horizontal beam member B of the second roof portion 12) in order to maintain a sense of design uniformity. Specifically, it is set to 19.65 °. By providing the horizontal beam member 20 in an inclined manner, it is possible to block the line of sight from the outside of the sunshade structure 10 and relieve the feeling of occlusion when viewed from the inside. In addition, as shown in FIG. 6, sunlight can be taken in also from between the crosspiece member C of this blindfold part 13. As shown in FIG.

  By the way, the horizontal beam member C of the blindfolded portion 13 is fixed to the column member 15 so that the front and back are opposite to the roof portion. In other words, the first long side surface 21 is fixed so as to be on the upper surface in the roof portion, but the second long side surface 22 is fixed so as to be on the upper surface in the blindfold portion 13. By attaching the front and back sides in this way, as shown in FIG. 3, the horizontal beam member 20 having the same shape can be used regardless of the difference in the extending direction between the column member 15 and the horizontal beam member 20. . That is, in this embodiment, since the column member 15 and the horizontal beam member 20 are continuously formed with substantially the same width, when the horizontal beam member 20 is attached to the blindfold 13 on the same front and back as the roof portion, Unless the beam member 20 is extremely inclined, the corners of the horizontal beam member 20 protrude forward and backward of the column member 15. In this regard, according to the present embodiment, the horizontal beam inclined at substantially the same inclination angle as the inclination angle of the second roof part 12 by attaching the horizontal beam member 20 to the blindfold 13 with the roof part and the front and back reversed. The member 20 can be accommodated in the width of the column member 15. Therefore, since it is not necessary to prepare separately the horizontal beam member 20 from which width differs, manufacturing cost can be suppressed.

  In this embodiment, the height of the 1st roof part 11, the 2nd roof part 12, and the blindfold part 13 is provided in the appropriate height according to each function.

  For example, the lower end of the lowermost cross beam member A among the horizontal beam members A constituting the first roof portion 11 is provided at substantially the same height as the upper end of the building opening 31, in other words, the first roof portion. 11 and the second roof portion 12 are provided at substantially the same height as the upper end of the building opening 31. For this reason, the 2nd roof part 12 is arrange | positioned ahead of the building opening part 31, and it forms so that the sunlight which passed the 2nd roof part 12 can be taken in from the building opening part 31 indoors effectively.

  In addition, the boundary between the second roof portion 12 and the blindfold portion 13 is a position higher than the intermediate position in the height direction of the building opening 31, in other words, the height of the lower end of the second roof portion 12 is The position is higher than the intermediate position in the height direction of the building opening 31. For this reason, when the blindfold 13 is provided so as to be continuous with the lower end of the second roof portion 12, the height of the line of sight when a person sits in the building and the height of the line of sight when a person stands in the building are increased. The blindfold portion 13 can be provided at a height that covers the gap (a height that does not allow eyes to be met by an external person when inside the building), and the blindfold effect can be effectively exhibited. Further, if the blindfold 13 is not provided, there is no shielding object that blocks the line of sight, so that a structure that does not give a feeling of pressure can be obtained.

  In the present embodiment, as shown in FIG. 2 and the like, the horizontal beam member 20 is not opened to the bottom of the blindfold 13 and the lower portion is opened, but this is not limiting, and the lowermost portion of the blindfold 13 is not limited thereto. You may make it attach the crosspiece member 20 to.

  As described above, according to the present embodiment, the first roof portion 11 disposed at a position close to the building opening 31, and at a position farther from the building opening 31 than the first roof portion 11. And the horizontal beam member A constituting the first roof part 11 is arranged in a substantially horizontal direction and the horizontal beam member constituting the second roof part 12. B is inclined and arranged such that the outdoor side is higher than the building opening 31 side. That is, the solar radiation from directly above is largely blocked at a position close to the building opening 31, and the solar radiation is likely to enter at a position away from the building opening 31. For this reason, the shade is formed near the building opening 31 by the first roof portion 11 during the daytime in summer when the sun rises, while the second roof portion 12 can be daylighted in the winter when the sunlight is low. Is formed. For this reason, it is possible to achieve both solar radiation blocking and daylighting without requiring adjustment operations and installation / storage, and appropriate solar radiation control according to the season and time zone can be performed.

  In addition, since such a structure is realized simply by changing the angle of the plurality of cross beam members 20 having the same cross-sectional shape, a complicated mechanism is not required and the number of types of parts can be reduced. Can be suppressed.

  Moreover, since the said cross beam member A which comprises the said 1st roof part 11 is arrange | positioned so that it may overlap when it projects from right above, it is near the building opening part 31 in the summer when the sunlight pours from right above. A large shade can be formed at the position.

  Further, since the plurality of column members 15 connected to the roof portion and provided substantially vertically are provided, and the crosspiece member 20 is disposed between the plurality of column members 15 to form the blindfold portion 13, Therefore, the blindfold function of the building opening 31 can be provided. And since the blindfold part 13 is formed using the same cross beam member 20 as a roof part, it can give a sense of unity also in design, and can also make manufacturing cost cheap.

  Moreover, since the said crosspiece member 20 is formed in the parallelogram in cross-sectional shape, it can perform moderate solar radiation control according to a season and a time zone. For example, by aligning the opposite sides of the parallelogram with the solar radiation angle in winter, it is possible to capture the maximum amount of solar radiation in winter and to block the sun when the sun rises in summer. be able to.

  Moreover, since the said horizontal beam member 20 is attached so that the front and back may be reversed by the said roof parts 11 and 12 and the said blindfolded part 13, making use of the shape of a parallelogram, the roof parts 11 and 12 are blindfolded. The solar radiation can be captured at substantially the same angle as the part 13.

  In the above-described embodiment, the cross-sectional shape of the horizontal beam member 20 is a parallelogram, but the present invention is not limited to this, and a horizontal beam member 20 of another shape may be used.

  Moreover, the attachment angle of the crosspiece member 20 in the above-described embodiment is merely an example, and the angle may be changed without departing from the gist of the present invention.

  Moreover, although the roof part was made into the structure of 2 steps | paragraphs of the 1st roof part 11 and the 2nd roof part 12, it is not restricted to this, For example, a roof part is divided | segmented into 3 steps or more, and the attachment angle of the crosspiece member 20 is set. It may be changed.
