Description

  INDUSTRIAL APPLICABILITY The present invention relates to a combination of daylighting roofs that can be used in a wide range of applications, such as roofs for residential verandas, carports, bicycle parking lots for apartments, or large facilities such as factories, warehouses, indoor sports facilities, and agricultural houses. Concerning structure.

  In recent years, on the roofs of verandas, carports, bicycle parking lots of apartment buildings, or the roofs of factories and warehouses, lighting power has been reduced by effectively incorporating natural light. Corrugated roofing materials having translucency, which can be reduced, are increasingly used.

  Such a corrugated roof material is obtained by superimposing a plurality of crests and troughs at the end of the roof material on a plurality of crests and troughs of the corrugated roof material adjacent thereto, and bolts and the like from above the overlapped part. Are connected by fixing to the purlin material (for example, Patent Document 1 and Patent Document 2).

Japanese Utility Model Publication No. 06-040153 JP 2006-104764 A

  However, the roof structure in which the roof materials are connected by the above construction method, when dust or the like enters the crests and crests of the overlapped portion, or the crevice between the troughs and the trough portions of the overlapped portion, Dust and the like are accumulated without being swept out, and the roofing material has translucency, so that the dust and the like may become conspicuous and impair the beauty. In addition, since a plurality of peaks and valleys are overlapped and connected, there is a problem that the translucency is lowered over a wide range.

  The present invention has been made in view of the above problems, and the problem to be solved is to suppress a decrease in aesthetics due to dust or the like entering a gap between the overlapping portions in the overlapping portion of the daylighting roof, and An object of the present invention is to provide a connecting structure for daylighting roofs that can suppress the floating of the part.

In order to achieve the above object, a connecting structure of daylighting roofs according to the present invention includes a side end portion of a roofing material having translucency composed of a mountain part and a valley part, and a roof similar to the above adjacent to it. A connection structure of daylighting roofs in which the other end portions of the materials are overlapped and connected, wherein the overlapping portions of the roof materials are covered from above by a cover member, and the translucency of the cover member is the roof rather smaller than translucency of wood, the inclination angle of the inclined surface of the other end side of the mountain portion of the one end of the roofing material, than the inclination angle of the inclined surface of the other end side of the mountain portion of the other end The crest at one end is smaller than the crest at the other end, and the crest at the other end of the roofing material is The crest that is superimposed on the upper side and the slope on the other side end side of the crest located on the upper side is located on the lower side only at the lower end. Contact with the inclined surface of the other end side, between the ridges positioned on the upper side and the peak portion located on the lower side, and is characterized in that the air gap to the extent that capillary action does not occur is formed.

In the connection structure of the lighting roof of this invention, it is preferable that the said cover member does not have translucency. Also, has a shape on SL cover member along said roofing, when covering the roofing material in the cover member, it is more preferable to make substantially no gap between the roof material and the cover member, the It is more preferable that the width of the cover member is wider than the width of the overlapping portion of the roof materials.

Since the connecting structure of the daylighting roofs of the present invention uses a roofing material having translucency, natural light can be taken in effectively, and illumination power and the like can be reduced. Moreover, even if dust or the like enters the gap between the overlapping parts by covering the overlapping part of the roofing material from above with a cover member having a lower light transmission than the roofing material, the light transmission of the cover member Since the property is smaller than that of the roofing material, the dust and the like are not conspicuous, and the deterioration of aesthetics can be suppressed. In addition, the connecting structure of the daylighting roof according to the present invention covers the overlapping portion of the roofing material from above by the cover member, so that the floating of the edge of the roofing material is suppressed and dust or the like hardly enters the gap. At the same time, the strength of the edge of the roofing material is improved. And even if the edge part of the roofing material is somewhat deformed, the shape is corrected by being pressed down by the cover member, so that there is no fear that rainwater blows into the gap between the roofing material and the roofing material due to wind and rain. In addition, the slope angle of the slope on the other side end side in the peak portion on one side end of the roofing material is smaller than the slope angle of the slope on the other side end side in the peak portion on the other side end. Is formed smaller than the peak at the other end, and the peak at the other end of the roofing material is superimposed on the upper side of the peak at the one end of the roofing material adjacent to the peak, and is positioned above the peak. The slope on the other side end of the part touches the slope on the other side end side of the mountain part located on the lower side only at the lower end, and between the mountain part located on the upper side and the mountain part located on the lower side, A gap that does not cause capillary action is formed, preventing rainwater from blowing between the upper and lower peaks, and preventing rainwater from entering between the upper and lower peaks due to capillary action. In addition, since the shape and size of the ridges above the overlapping portion are not different from those of the ridges other than the overlapping portion, the appearance is improved.

  Further, in the connecting structure of the daylighting roofs in which the cover member does not have translucency, dust or the like that has entered the overlapping portion of the roofing materials cannot be visually recognized, and the appearance is not deteriorated.

As mentioned above, when roof materials are connected using a cover member that does not have translucency and a cover member that is less translucent than the roof material, the translucency decreases at that portion. can not deny. Therefore , it is desirable to take as many lighting surfaces as possible by connecting the ridges on one side edge of the roofing material and the ridges on the other side edge of the roofing material adjacent to each other. Even so, the connecting structure of the daylighting roof of the present invention improves the connection strength of the end portion of the roof material by using the cover member .

  And, the cover member has a shape along the roof material, and when the roof material is covered with the cover member, the connecting structure of the daylighting roof is such that there is substantially no gap between the roof material and the cover member. Dust and the like are less likely to enter between the member and the roofing material. Further, by making the shape of the cover member along the roof material, the lifting of the end of the roof material is more reliably suppressed, and the connection strength between the roof materials is further improved.

  Furthermore, the connecting structure of the daylighting roof in which the width of the cover member is wider than the width of the overlapping portion of the roofing material covers the entire overlapping portion of the roofing material with the cover member. Dust and the like are less likely to enter. Further, even if dust or the like enters, the dust or the like accumulated near the edge of the overlapping portion can be covered by the cover member, so that the dust or the like is not conspicuous.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  The present invention relates to a connecting structure of daylighting roofs that can be used for a wide range of applications, such as roofs of housing verandas, carports, bicycle parking lots of apartment houses, or roofs of large facilities such as factories and warehouses. As shown in FIG. 1 and FIG. 2, the end portion of one roof material 1 fixed to the purlin material 6 and the end portion of the other roof material 1 adjacent thereto are overlapped and connected.

  As shown in FIG. 4, the roofing material 1 used for the connecting structure of the daylighting roofs is composed of a plurality of mountain parts 1a (four in this embodiment) and a plurality of valleys 1b (three in this embodiment). The constructed folded plate roof has a length substantially equal to the length of the roof in the front-rear direction, and a width substantially equal to a width dimension obtained by dividing the roof width into a plurality of widths. This roofing material 1 uses a folded roof made of synthetic resin having translucency in order to effectively take in natural light, and is formed of synthetic resin such as polycarbonate resin, acrylic resin, polyethylene resin, polypropylene resin and the like. However, in particular, the roofing material 1 made of polycarbonate resin is preferably used because it is excellent in weather resistance and impact strength and has good transparency.

As shown in FIG. 4, both end portions of the roof material 1 are mountain portions 1 a and 1 a, and as shown in FIG. 3, the mountain portion 1 a at one end of the roof material 1 is adjacent to the mountain portion 1 a. the crest 1a of the other side edge of the roofing material 1 are overlapped only one mountain, the superposition portion OL by covering from above by a cover member 2 to be described later, linking the roofing material 1 adjacent thereto and the roofing material 1 It has come to be. This roofing material 1 is different in the ratio of the width of the peak 1a and the valley 1b (the width of the valley 1b is larger than that of the peak 1a. Here, the ratio of the width of the peak 1a and the valley 1b is 1: 6. In such a roofing material 1 in which the ratio of the widths of the peak part 1a and the valley part 1b is different, when the plurality of peak parts 1a, 1a,. Since the area of the part OL increases and the roofing material 1 is required more than necessary, the translucency is also lowered, which is not preferable. Therefore, it is preferable that the mountain parts 1a and the mountain parts 1a are overlapped by only one mountain and the roof materials 1 and 1 are connected to each other. When the end of the material 1 is deformed, there is a risk that rainwater blows between the roofing materials 1 and 1 due to wind and rain and leaks. Therefore, in the connecting structure of the daylighting roof of the present invention, in order to prevent such a problem, the shape is corrected by pressing the connecting portion from above with a cover member 2 having a shape along the roofing material 1 to be described later. Can be prevented.

As shown in FIGS. 3 and 4, the peak portion 1 a at the left end portion (one side end) of the roof material 1 is inside the peak portion 1 a at the right end portion (the other end) of the roof material 1 adjacent thereto. It is formed so as to be lower by the thickness t of the roofing material 1 so as to be accommodated in the housing, and is smaller than the peak portion 1a at the right end portion . And the peak part 1a formed in the left side edge part of the roofing material 1 has the inclination | tilt angle (theta ) 1 of the slope of the right side (other side edge side) of the right side (other side edge side) of the mountain part 1a of a right side edge part. The slope angle θ2 of the slope is smaller than this, and if the slope angles θ1 and θ2 of the slopes of the left and right peaks 1a and 1a are formed to be different, the peaks 1a and 1a are formed as shown in FIG. Are overlapped, a space S is formed between the upper peak 1a and the lower peak 1a.

The space S is formed so that rainwater does not enter due to capillary action. That is, when the overlapped side edge portions of the roofing 1,1 does not cause the above capillarity problem if complete contact, usually adjacent to the one side edge of the roofing material Yamabe When the ridges at the other end of the roofing material are overlapped, as shown in FIG. 5, due to the dimensional accuracy of the product, etc., between the ridge 100a located on the upper side and the ridge 100a located on the lower side. In addition, a slight gap is generated. As described above, when a halfway gap is generated between the upper peak portion 100a and the lower peak portion 100a, rain rises along the gap between the peak portion 100a and the peak portion 100a due to the capillary phenomenon, and the roofing material. There is a possibility of water leaking around the lower surface of the water. Therefore, according to the present invention, a space S that does not cause capillary action is formed between the peak portion 1 a located on the upper side of the roof material 1 , 1 and the peak portion 1 a located on the lower side. the inclination angle θ1 of the inclined surface of (one side end) the formed right ridges 1a (the other end side), the right (the other end side of the crest 1a formed at the right end (the other end) ) Is intentionally secured by making it smaller than the inclination angle θ2 of the slope . As a result , the capillary phenomenon is prevented from occurring in the overlapping portion between the side edges of the roofing materials 1, 1, and there is no fear of water leaking around the lower surface of the roofing material 1.

Moreover, when this roofing material 1 overlaps the side edge parts of the roofing materials 1 and 1, as shown in FIG. 3, the right side edge part (other side edge) of one roofing material 1 located on the upper side is shown. The slope on the right side (other side end side) of the mountain portion 1a is the right side (other side end side ) of the mountain portion 1a of the left side end portion (one side end) of the other roofing material 1 located below only at the lower end. ) To come into contact with the slope. As described above, in the connecting structure of the daylighting roofs of the present invention, the space S is formed in the overlapping portion OL so that the capillary phenomenon does not occur when the side ends of the roofing materials 1 and 1 are overlapped. The However, even when forming the space S, without the lower end of the right slope of the upper roof member 1 mountain portion 1a abut against the right side of the slope of the lower roof member 1 crests 1a, FIG. 6 as shown in, when the upper ridges 101a gap which is open between the right slope of the lower end and the lower roof member of the right slope of the mountain portion 101a of the roofing material will be formed, the water leakage due to capillary action Even if it can be prevented, rainwater is blown between the mountain portions 101a and 101a due to wind and rain, which may cause problems such as water leakage. To prevent such a problem, in the present invention, the lower end of the slope of the upper roof member 1 crests 1a right (the other end side), the lower the roofing material 1 crests 1a right (other It is formed so as to be in contact with the slope on the side end side .

  The roof material 1 having the above-mentioned configuration is not particularly limited because various sizes are used depending on the size of the roof at the construction site, but the width is 500 to 1000 mm, the length is 250 to 3000 mm, and the mountain portion. A roofing material 1 in which the distance between the top of 1a and the top of the mountain 1a is 200 to 350 mm, the thickness t is 1.5 to 5 mm, the height of the mountain 1a is 10 to 30 mm, and the width of the mountain 1a is about 10 to 60 mm. Are preferably used. And such roofing materials 1 and 1 are connected by the cover member 2 demonstrated below.

  As shown in FIG. 1, the cover member 2 is a long member formed to have a length substantially the same as the length of the roof material 1, and has a shape of a mountain portion 1 a at the right end portion of the roof material 1. It is formed in a mountain shape along. Therefore, when the roof material 1 is covered with the cover member 2, as shown in FIG. 3, the gap between the roof material 1 and the cover member 2 is substantially eliminated. As a result, dust or the like is less likely to enter between the cover member 2 and the ridge 1a at the end of the roofing material 1 is reliably prevented from rising, and the connection strength between the roofing materials 1 and 1 is improved. Further, the width W2 of the cover member 2 is wider than the width W1 of the overlapping portion OL of the roof materials 1 and 1, and thus the width W2 of the cover member 2 is set to the roof materials 1 and 1 each other. By making it wider than the width W1 of the overlapping portion OL, it becomes possible to cover the entire overlapping portion OL of the roof materials 1 and 1 with the cover member 2, and between the roof materials 1 and 1 or It becomes difficult for dust or the like to enter between the roof material 1 and the cover member 2.

  The cover member 2 is more transparent than the roof material 1 so that even if dust or the like enters between the roof materials 1 and 1 or between the roof material 1 and the cover member 2, they do not stand out. The nature is getting smaller. In the present embodiment, the cover member 2 having a light transmittance of 0%, that is, having no translucency is used. In general, if dust or the like enters between the roofing materials 1 and 1 or between the roofing material 1 and the cover member 2, it can be visually recognized as darkened dirt, which may impair the beauty. In order to make it inconspicuous, the lightness L * of the cover member 2 is preferably 60 or less (lightness L * means the lightness L * in the L * a * b * color system defined in JIS Z 8729). When the overlapping portion OL of the roof materials 1 and 1 is covered with such a cover member 2, even if dust or the like enters between the roof materials 1 and 1 or between the roof material 1 and the cover member 2, The cover member 2 is hidden by the cover member, and the cover member 2 is covered with dark stains and becomes inconspicuous. In addition, as described above, the width W2 of the cover member 2 is the overlapping portion OL between the roof members 1 and 1. Since it is wider than the width W1 and covers even dust accumulated near the edge of the overlapping portion OL, the dust does not stand out and the aesthetic appearance is not impaired.

  The cover member 2 is made of a metal such as aluminum or SUS, or a synthetic resin such as polycarbonate or vinyl chloride resin. Among them, the cover member 2 made of aluminum and having a thickness of about 2 mm is used. It is particularly preferably used because of its good workability and light weight.

  On the other hand, if only dust or the like is to be blinded, a member (for example, a flat plate) instead of the cover member 2 as described above may be interposed in the gap between the peak portion 1a and the peak portion 1a of the roof material 1,1. However, even if a member in place of the cover member 2 is interposed in the gap between the roof materials 1 and 1 as described above, when the roof materials 1 and 1 are overlapped with each other, The peak portion 1a cannot be suppressed, and dimensional accuracy is required more than that of the cover member 2. If the dimensions are out of order, it will cause lifting, which is not preferable. In addition, by inserting a member in place of the cover member 2 below the peak portion 1a located on the lower side, dust and the like can be blindfolded, but the peak portions 1a, 1a of the roofing materials 1, 1 cannot be suppressed at all, Since the overlapping portion OL cannot be covered over the entire width, dust or the like is not blinded, which is not preferable. For the above reasons, it is most suitable that the overlapping portion OL between the roofing materials 1 and 1 is covered with the cover member 2 from above as in the present invention.

  Using the cover member 2 having the above configuration, the roof materials 1 and 1 are connected to each other. That is, as shown in FIGS. 2 and 3, one roof material 1 (right side) is placed on the main building material 6 and attached to the main building material 6 with a fixture (not shown). The ridge 1a at the right end of 1 (left side) is overlapped with the ridge 1a at the left end of the roofing material 1 located on the right side. And, by overlapping one peak portion 1a and the other peak portion 1a in this way, covering the overlapping portion OL with the cover member 2 from above, and fixing to the purlin member 6 with the bolt 3, Roof materials 1 and 1 are connected to each other. The bolt 3 has a through hole 10 a, 10 a, 2 a in the roof material 1, 1 and the cover member 2, and the cylindrical body 4 is disposed in the through hole 10 a, 10 a, 2 a, and then the cylindrical body through the washer 5. 4 and is fixed to the purlin 6 by tightening the bolt 3 from above, so that the roof materials 1 and 1 and the cover member 2 are firmly connected. The cylindrical body 4 used at this time has a flange portion 4a formed at the upper end, and serves to hold the cover member 2 from above and support the head of the bolt 3 by the flange portion 4a. The cylinder 4 also serves as a spacer that prevents deformation of the cover member 2 and the roofing materials 1 and 1 due to overtightening of the bolt 3.

  Since the connecting structure of the daylighting roof of the present invention as described above uses the roofing materials 1 and 1 having translucency, it is possible to effectively take in natural light and reduce illumination power and the like. Further, the overlapping portion OL is covered from above by the cover member 2 having a light transmittance of 0%, so that dust or the like enters between the gap between the peak portion 1a and the peak portion 1a or between the roof material 1 and the cover member 2. Even so, since the cover member 2 is not translucent at all, dust or the like is not conspicuous and there is no fear of impairing the beauty. Moreover, the present invention connects the roofing material 1 and the roofing material 1 only by overlapping the mountain portions 1a and 1a of the roofing materials 1 and 1 to each other. it can. In addition, since the cover member 2 suppresses the floating of the end portion of the roof material 1, dust and the like are less likely to enter, and the strength of the end portion of the roof material 1 is improved. Furthermore, even if the end of the roofing material 1 is somewhat deformed, the shape is corrected by being pressed down by the cover member 2, so there is a concern that rainwater will blow into the gap between the roofing material 1 and the roofing material 1 due to wind and rain. There is a remarkable effect of disappearing.

In the present embodiment, in order to minimize the degradation of the light-transmitting, but are linked by superposing crests 1a and mountain portion 1a of the both side ends only one mountain, the mountain portion 1a and the ridges When connecting folded plate roofs with a short interval 1a, one or more mountains may be overlapped and connected.
