FIG. 4 is an exploded perspective view showing a state in which the top light of FIGS. 1 to 3 is attached.

  1-4, as an example of the outer wall structure, the roof structure 1 has a base plate 3 such as a plywood fixed to the outdoor side of the field edge 2, and is about 1/100 to 2/100 along the X direction. It has a gentle slope. The field edges 2, 2... Are fixed in parallel at a predetermined interval of about 450 mm, and a steel pipe having a rectangular cross section is used. In the toplight T1 that is a daylighting member of the present invention, for example, the base plate 3 between two field edges is cut out to form a base opening 4 and is fixed to the outdoor side of the base opening. The field edges 2 and 2 are connected by horizontal rails 2 a and 2 a so as to surround the base opening 4. A metal plate 5 is laid on the outer surface of the base plate 3 to cover the base material 3. As the metal plate 5, a plate having a stainless steel thickness of about 0.3 to 0.6 mm is used. A plate material such as a vinyl chloride resin-coated steel plate may be used as the metal plate material.

  The top light T1 is used as a light source for the roof structure 1, and includes an opening frame 10 fixed to the roof structure 1, an opening cover 20 fixed to the outdoor side of the opening frame, and a seal on the outdoor side of the opening cover. As a material, a lighting plate material fixed with a gasket 30 in between is provided, and a netted glass plate 35 is preferable as the lighting plate material. The gasket 30 is made of EPDM (ethylene propylene diene rubber) and fixed in a double manner. The gasket 30 may be one in which EPDM is formed in a sponge shape, and is preferably provided with an adhesive on at least one surface. An O-ring or the like may be used as the sealing material.

  The opening frame 10 is formed by joining four outer peripheral frame pieces at right angles to surround the periphery and opening the inside in a rectangular shape. The outer peripheral frame piece of the opening frame is formed by bending a relatively thick stainless steel plate having a thickness of about 0.5 to 1 mm. In this embodiment, the outer peripheral frame piece in the horizontal direction and the outer peripheral frame piece in the vertical direction are cross sections. The shape is different. The cross-sectional shape of the outer peripheral frame piece in the vertical direction is that the bottom surface portion 11, the inner extension portion 12 and the outer extension portion 13 that extend at right angles from both ends of the bottom surface portion, and the bottom surface portion 11 inward from the inner extension portion 12. And a flat portion 14 that extends in parallel with the outer extended portion 13 and a folded-back portion 15 that is bent acutely toward the indoor side from the outer extending portion 13 toward the outer peripheral side.

  The outer peripheral frame piece in the horizontal direction has a shape without the folded portion of the outer peripheral frame piece in the vertical direction, and includes a bottom surface part 11, an inner extension part 12, an outer extension part 13, and a flat part 14. Thus, the two outer peripheral frame pieces facing the opening frame 10 have a shape in which folded portions 15 are formed on the outside. The opening frame 10 has a center bottom surface portion 11 disposed corresponding to the field edge 2 and the horizontal rail 2a of the roof structure 1 and fixed by a tapping screw 16 or the like. Of course, the four outer peripheral frame pieces may have the same cross-sectional shape including the folded portion.

  The opening cover 20 is formed by bending two long sides of a long stainless steel plate to the indoor side, and the outdoor side is a flat surface 21. The opening cover 20 is bent toward the indoor side at two locations on the outer peripheral side of the flat surface 21 in a direction of about 45 degrees to form a falling portion 22, and a lower end portion of the falling portion is formed with an engaging portion 23 protruding inward. The engaging portions are an inner bent portion 23a bent to the inner peripheral side, an outer bent portion 23b bent to the outer peripheral side, and a rounded portion 23c at the lower end. As described above, the engaging portions 23 and 23 are formed to face each other along the long side of the opening cover 20.

  An opening 24 having an arbitrary length is formed on the flat surface 21, and a stud bolt 25 protruding outward is fixed around the opening of the flat surface 21 of the opening cover 20 by welding or the like. The stud bolt 25 fixes a netted glass plate 35 as a flat daylighting plate material having translucency, and a cap nut 26 is screwed to the upper end between the netted glass plate 35 and the cap nut 26. Packing 27 is sandwiched. A heat insulating material 28 such as hard urethane foam filling the space between the base material 3 and the back surface side in the long side direction of the opening cover 20 is filled. Instead of the completely flat meshed glass plate 35, a substantially flat plate material such as a gently curved plate material or a plate material formed of a part of a spherical surface having a large curvature radius may be used.

  The opening cover 20 has a central portion in the short side direction as an opening 24, and the end of the flat surface 21 on the opening side is configured to contact the flat portion 14 of the opening frame 10. Then, the engaging portion 23 of the opening cover 20 is brought into elastic contact with the step formed on the indoor side of the folded portion 15 of the opening frame 10, and the flat surface 21 of the opening cover 20 and the flat portion 14 of the opening frame 10 are engaged. However, the opening cover 20 is fixed to the opening frame 10 by being connected by the tapping screws 17. On the inner periphery of the stud bolt 25 on the upper surface of the flat surface 21 of the opening cover 20, the gasket 30 is doubled.

The netted glass plate 35, which is a daylighting plate material, is fixed so as to cover the opening 24 of the opening cover 20, and has a thickness of about 6.8 to 9 mm. This meshed glass plate has a length of one side of about 450 mm and a length of the other side of up to 2700 mm on the basis of 450 mm. Therefore, the top light T1 of the present embodiment can form an opening having a width of about 450 mm and a length of up to about 2700 mm. The meshed glass plate 35 has corner cut portions 36 formed at four corners, and fixing through holes 37 formed along the four sides of the outer periphery.

  The meshed glass plate 35 is fixed to the outdoor side of the opening cover 20 with a cap nut 26 by inserting the stud bolt 25 of the opening cover into the through hole 37. Since the base roof structure 1 has a gentle slope as described above, and the amount of protrusion of the opening frame 10 and the opening cover 20 from the base material 3 is constant, the meshed glass plate 35 also has a gentle slope on the upper surface. Fixed. With such a configuration, outdoor brightness is supplied to the indoor side through the meshed glass plate 35. In addition, it is good also as a corner round part instead of the corner cut part of the glass plate 35 with a net | network.

  When the top light T <b> 1 configured in this way is attached to the roof structure 1, the end of the metal plate 5 is engaged with the folded portion 15 of the opening frame 10. Specifically, as shown in FIG. 2b, the rising edge 5a is formed by bending the edge of the metal plate 5 at right angles to the outdoor side, and the bent portion 5b is bent continuously at an acute angle. And an inclined portion 5c is formed by bending the rising portion 5a at an acute angle. The folding angle of the folded portion 5b is preferably set to be substantially equal to the angle of the folded portion 15 of the opening frame 10, and the inclined portion 5c surrounds the edge of the folded portion 15. With this configuration, the rising portion 5a at the edge of the metal plate 5 is positioned on the acute angle side of the folded portion 15 of the opening frame 10, and the edge of the metal plate wraps around the folded portion 15 so that the space between the two is reliably closed. , Rain water and the like can be prevented from entering.

  The installation work of the top light T1 of this embodiment configured as described above will be described below. When the top light T1 is attached to the roof structure 1, the base plate 3 inside the field edges 2 and 2 is removed to form a rectangular base opening 4. An opening frame 10 is fixed around the base opening 4. First, the bottom surface portion 11 of the opening frame 10 is brought into contact with the surface of the base material 3, and the tapping screw 16 is passed through the bottom surface portion 11 to fix the opening frame 10 to the field edges 2 and 2 and the horizontal rails 2 a and 2 a. Since the opening frame 10 is open on the outdoor side of the bottom surface portion 11, it can be easily fixed to the roof structure 1 with the tapping screw 16.

  The edge part of the metal plate 5 that covers the surface of the base plate 3 of the roof structure 1 is bent up to the outdoor side to form the rising part 5a, and the folded part 5b and the inclined part 5c are continuously formed. The rising portion 5a is inserted into the stepped portion of the folded portion 15 of the opening frame 10, and the folded portion 15 is connected so as to be surrounded by the folded portion 5b and the inclined portion 5c and fixed to the opening frame 10. A heat insulating material 28 such as hard urethane foam is installed at the end on the short side where the engaging portion 23 of the opening cover 20 of the opening frame 10 is not engaged. In the case of an existing roof structure, the edge portion of the metal plate covering the base material 3 is subjected to the above processing and connected to the opening frame 10.

  Thereafter, the opening cover 20 is fixed to the opening frame 10 fixed to the base material 3 of the roof structure 1. The opening cover 20 is tapped by engaging the engaging portions 23 and 23 on the outer peripheral side with the folded portions 15 and 15 of the opening frame 10 so that the flat portion 14 of the opening frame 10 and the flat surface 21 of the opening cover 20 are in contact with each other. Screw 17 is fixed by screwing. When the tapping screw 17 is screwed in, the folded portions 15, 15 formed by engaging portions 23, 23 formed on both sides along the long side of the opening cover 20 rising on both sides along the long side of the opening frame 10. It can be easily done because it is temporarily fixed by being engaged with.

Since the engaging portion 23 includes the inner bent portion 23a, the outer bent portion 23b, and the rounded portion 23c, the engaging portion 23 can be easily engaged with the opening frame 10. Since the engaging portion 23 of the opening cover 20 covers the connecting portion between the opening frame 10 and the metal plate 5 from the outer periphery, the waterproof property can be further improved, and water leakage can be reliably prevented even when the wind and rain are strong. The opening cover 20 has an engaging portion 2 at a portion where the opening frame 10 is provided.
3 and 23 engage with the folded portions 15 and 15 and the folded portion 5b and the inclined portion 5c of the metal plate material 5, but only engage with the folded portion 5b and the inclined portion 5c of the metal plate material 5 in the portion where the opening frame 10 is not provided. .

  Thereby, the opening frame 10 is fixed to the outdoor side of the roof structure 1, and the opening cover 20 is fixed to the outdoor side in a state of protruding. That is, the opening cover 20 is formed so as to protrude in a hill shape from the metal plate material 5 that is a flat surface of the roof structure 1, and a portion without the opening frame 10 on the back surface side of the opening cover is positioned with the opening cover 20. The space with the base material 3 is filled. After that, the gaskets 30 are double-fixed on the flat surface 21 of the opening cover 20 and fixed. The double gasket 30 is attached to the inner peripheral side of the stud bolt 25.

  The through hole 37 of the meshed glass plate 35 is fitted into the stud bolt 25 of the opening cover 20, and the meshed glass plate 35 is brought into contact with the gasket 30. Then, the packing 27 is fitted to the protruding end of the stud bolt 25, and the cap nut 26 is screwed and fixed. As a result, the central opening 24 of the opening cover 20 is covered with the flat meshed glass plate 35. As a result, the gasket 30 can be seen through from the outdoor side through the meshed glass plate 35, and can be easily visually inspected when the gasket 30 is deteriorated due to aging or the like, or when the waterproof state is lowered. As a result of inspection, if the gasket 30 needs to be replaced, the meshed glass plate 35 can be removed from the opening cover 20 by simply removing the cap nut 26 screwed into the stud bolt 25, and the gasket 30 can be easily removed. Can be exchanged.

  The top light T1 and the mounting structure thereof configured as described above have a flat shape as a whole, and can be easily mounted on a flat roof, particularly a metal roof structure. During the rain, rainwater on the meshed glass plate 35 flows along a water gradient, and rainwater that has entered the gap between the meshed glass plate 35 and the opening cover 20 is prevented from entering the indoor side by the gasket 30. In addition, rainwater on the metal plate 5 flows along a water gradient (X direction), and rainwater close to the opening frame 10 is prevented from entering the interior by the rising portion 5a. Furthermore, since the netted glass plate 35 is used as a lighting plate material, and the opening frame 10 and the metal plate material are formed of a stainless steel plate, a non-flammable top light having high durability and its mounting structure can be obtained. Moreover, it is a flat structure and has a structure excellent in maintenance.

  In addition, the connection part of the opening frame 10 and the metal plate material 5 and the engaging part of the opening frame 10 and the opening cover 20 are not limited to the shapes as described above, but as shown in FIG. 15 may be inserted only by the rising portion 5a at the edge of the metal plate 5, and although not shown, the engaging portion may be configured such that a bent portion bent at a right angle is engaged with the folded portion of the opening frame. . Further, the sectional shape of the opening frame is such that the outer peripheral frame side outer extending portion 13A of the opening frame 10 on the side where the engaging portion 23 of the opening cover 20 is not engaged has no folded portion as shown in FIG. The shape which contacts 20 may be sufficient.

  Another embodiment of the present invention will be described in detail with reference to FIGS. FIG. 7 is a cross-sectional view of a main part of another embodiment of the daylighting member according to the present invention, and FIG. 8 is a perspective view in which a part of the main part is broken. In addition, this embodiment is characterized in that the top light T2 further includes a translucent heat insulating material 40 in a state parallel to the meshed glass 35 plate located on the outdoor side as compared with the above-described embodiment. Other substantially equivalent configurations are denoted by the same reference numerals, and detailed description thereof is omitted.

  7 and 8, the top light T2 further includes a translucent heat insulating material 40 in parallel with the netted glass plate 35, which is a daylighting plate material, with a space on the indoor side. The translucent heat insulating material 40 is formed by laminating a plurality of plastic corrugated cardboards 42 with support frames 41 located on four sides. The translucent heat insulating material of the present embodiment is formed by laminating a plurality of plastic corrugated cardboards at a predetermined interval, surrounding the outer periphery with a frame, and having a rectangular shape in plan view. The translucent heat insulating material 40 has a shape that fits into the base opening 4.

  A plurality of ribs 41a are formed on the inner periphery of the support frame 41, and a plastic corrugated cardboard 42 is inserted between these ribs to maintain a separated state. Further, a fixing rib 41b is formed to extend on the outer peripheral side of the support frame 41, and the translucent heat insulating material 40 is fixed by sandwiching the rib between the base material 3 and the opening frame 10. An extruded material such as aluminum or plastic is used as the support frame 41, a plurality of ribs 41a are formed at a predetermined interval integrally with the flat portion, and a fixing rib 41b is formed. It is preferable to drop it into the step 4a.

  Thus, the translucent heat insulating material 40 is formed with a space 43a between the meshed glass plate 35 and the plastic corrugated cardboard 42 as the first heat insulating material located on the outdoor side, and a plurality of plastic corrugated cardboards 42. , 42 are formed with spaces 43b, 43b, respectively, and by making all the gaps of the plurality of layers of spaces 43a, 43b 20 mm or less, fluid such as air inside can be convected. This prevents the heat insulation performance. In addition, the said gap | interval is the distance space | interval of the perpendicular direction of each board | plate material.

  When each plastic corrugated cardboard 42 is inserted between the ribs of the support frame 41, the spaces 43b and 43b can be sealed in an airtight state by inserting packing or injecting a caulking agent. When the plurality of spaces 43b and 43b are sealed, it is preferable to fill the inside with dry air, and nitrogen gas or the like may be enclosed instead of the dry air. Further, a small hole for ventilation (not shown) may be formed in the support frame 41 without sealing each space so that the air inside flows. The plastic corrugated boards 42, 42... That form a plurality of heat-insulating layers are soft and easy to bend. If they are bent, the gap between the spaces will be different and may be 20 mm or more. Therefore, it is possible to adopt a configuration in which the dimensions of the space are difficult to change.

  The plastic corrugated cardboard 42 used as a heat insulating plate material having a plurality of translucency has a total thickness of about 3 to 5 mm, two plastic thin plate materials (0.1 to 0.3 mm thickness), and these The intermediate girder is formed of a thin plastic material having a similar thickness and is continuously joined at intervals of about 3 to 5 mm. For this reason, it has the structure where the air layer for heat insulation is formed in the middle of two sheets of plastic sheet material. The plastic thin plate is formed from a resin such as polypropylene or polycarbonate, and a polycarbonate resin is preferable in consideration of weather resistance. The plastic corrugated cardboard 42 is transparent or milky white, and the light transmittance is appropriately set.

  It is preferable that the number of plastic corrugated cardboards constituting the translucent heat insulating material 40 is selected depending on an area where a house or the like that employs the panel is built. For example, since the difference between the outdoor temperature and the indoor temperature is large in a cold region, the heat insulation performance can be improved by increasing the number of plastic corrugated cardboards 42 and forming the space 43 with a multi-layer structure. Further, since the light transmittance is relatively lowered when the number of heat insulating plate members is increased, it is preferable to set the number based on desired heat insulating performance and transmittance.

  The toplight T2 of this embodiment has the same effect as that of the above-described embodiment, and further includes a translucent heat insulating material 40 on the indoor side in parallel with the meshed glass plate 35. In summer, heat from sunlight during the day can be prevented from entering the indoor side, and in winter, heat from the heating can be prevented from escaping to the outside through the top light T2. Furthermore, it is possible to prevent dew condensation due to a temperature difference between indoor and outdoor, and to secure a comfortable living space. Although the translucent heat insulating material 40 is fixed between the base plate 3 and the opening frame 10, it may be fixed directly to the opening frame or may be fixed to the field edge. Good.

That is, in the translucent heat insulating material 40, a plurality of spaces 43 are formed by a plurality of plastic corrugated cardboards 42, and the gaps between these spaces are set so that the internal fluid does not convect. Convection is a phenomenon in which heat and materials are transported by macroscopic movement (flow) of a fluid such as gas or liquid. If a temperature difference occurs in the fluid, a density difference due to thermal expansion will occur, and buoyancy will occur in parts with low density In response to this, a circulating flow is generated in which a portion having a high density descends instead of being transferred, and heat is transmitted, but the translucent heat insulating material 40 of the present embodiment sets the gap of the space 43 to 20 mm or less. Therefore, since the convection as described above is prevented, the heat insulation performance is excellent.

  Although one embodiment of the present invention has been described in detail above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention described in the claims. Design changes can be made. For example, the roof structure has been shown as an example composed of a metal field edge and a plywood base plate. However, a roof structure including a wooden base material such as a rafter or a structure using an ALC plate and a waterproof sheet can be used. Good. Moreover, as a heat insulating material installed on the back surface side of the opening cover, a heat insulating material such as glass wool or rock wool may be used.

  Although an example of a meshed glass plate is shown as a flat daylighting plate material having translucency, a translucent plastic plate such as an acrylic plate or a polycarbonate plate may be used. Further, the plastic plate may be a smoked low transmittance type or a colored plate, a type having a UV cut effect, or a type subjected to various surface treatments. Furthermore, a tempered glass with a plastic sheet sandwiched between them, or a glass plate material reinforced with glass fiber or the like may be used. The daylighting member is not limited to a rectangular shape in plan view, but may be an appropriate shape such as a circle.

  When a substantially flat plate that is gently curved is used as the lighting plate material, it is preferable to gently curve the upper surface of the opening cover in accordance with the lighting plate material, but a sealing material having a large shrinkage rate such as a foaming sealing material is used. It may be used and sealed.

  As an application example of the present invention, the daylighting member can be attached to an outer wall structure having a vertical outer wall material such as a wall panel, and can also be applied to a lighting application such as a wall surface. It can also be applied to a steep roof structure such as a tiled roof structure.
