 The present invention relates to a mounting structure for mounting a skylight panel to an opening frame of a skylight that has excellent heat insulation and dew condensation prevention properties and effectively shines sunlight, and more specifically, a skylight panel having large flexibility and high brittleness. The present invention relates to a mounting structure that can be easily mounted to an opening frame while ensuring watertightness and airtightness.

[0002]

[Prior Art]

 The skylight for daylight draws sunlight from the rooftop or roof, so an opening is formed in the rooftop or roof, or on the side wall of the frame, and a transparent frame is fixed through the opening. It has a structure in which a skylight panel is fitted.

The structure for attaching the skylight panel to the opening frame is not only airtight and watertight, but is also a structure that simultaneously satisfies various performances such as heat insulation, fire resistance, and dewproofness. It is required, and it is necessary that the structure be such that both can be attached by a simple operation. On the other hand, in recent daylight skylight devices, the size of the skylight main body has been particularly increased in order to improve the efficiency of daylighting, and a plurality of panels are often connected to one skylight.

FIG. 3 shows an example of a structure for attaching a skylight panel to a conventional general opening frame. In the figure, reference numeral 1 denotes an opening frame body made of an aluminum extruded mold material, which has a large number of bolt insertion holes at its upper open end and is formed with a mounting portion 1a of a skylight panel 2 extending outward at a right angle. The skylight panel 2 is attached to the attachment portion 1a by a bolt 6 and a nut 7 via a ring-shaped rubber packing 3, a band-shaped packing 4 and a washer 5 which are stretched around the opening frame 1 on four sides. ..

According to the illustrated example, a glass support piece for mounting and fixing the netted glass 8 on the inner wall surface of the rising portion of the opening frame 1 via the gasket 9 in order to secure heat insulation and dew resistance. 1b is horizontally extended. The opening frame 1 is fixed to an opening of a roof part (not shown) via an anchor metal piece 10.

The skylight panel 2 is made of a molded product of acrylic resin, polycarbonate resin, or the like, is molded in a dome shape in the illustrated example, and is attached to the opening frame body 1 having a large number of bolt insertion holes at its periphery. Is formed with a flange 2a.

FIG. 4 shows an example of a different attachment structure of a skylight panel to a conventional opening frame. According to this example, the mounting structure of the skylight panel 12 with respect to the opening frame 11 is a combination structure in which a panel mounting frame 13 is newly added to the opening frame 11.

According to the illustrated example, the opening frame body 11 is an example including upper and lower two frame bodies 11a and 11b in which the upper frame body 11a is opened and closed, and the mounting structure of the skylight panel 12 in the upper frame body 11a is as shown in FIG. As shown in FIG. 5, the upper frame 11a has a cross-section of the upper end member which is substantially cross-shaped, and the left and right horizontal pieces 11c and 11d are bent at right angles up and down respectively. The lower frame 11b has the same structure as the conventional one except that a packing material is attached to the upper end surface.

One panel mounting frame 13 is shaped to fit into the upper frame body 11a having a substantially L-shaped cross section composed of a horizontal portion 13a and a rising portion 13b. Then, on the inner wall surface of the rising portion 13b, a lower horizontal piece 13c having a large number of bolt screw holes formed at a predetermined interval and an upper portion of the lower horizontal piece 13c are arranged and have a substantially L-shaped cross section. And an engaging piece 13d extending in the same direction as the projecting extension.

When the skylight panel 2 is attached to the upper frame body 11a, the corrugated glass 7 and the flange 2a of the panel 2 are respectively strip-shaped on the inner end surface of the open end of the upper frame body 11a as shown in FIG. The panel mounting frame 13 is mounted on the open end of the upper frame 11a while being mounted via the packing material. After this fitting is completed, the bolt 14 previously attached to the bolt screw hole is tightened, and the tip of the bolt 14 pushes up the lower surface of the left horizontal piece 11c of the upper frame body 11a. The horizontal portion 13a of the mounting frame 13 is pulled down, and the flange 2a of the skylight panel 2 and the netted glass 7 are stacked on top of each other via the packing material to form the upper frame body 11a and the panel mounting frame 13 respectively. It is pinched by compression.

According to the mounting structure of the skylight panel 2 with respect to the opening frame bodies 1 and 11 described above, both of them satisfy the above-mentioned requirements regarding performance, and at the same time, mounting work can be performed by tightening bolts 6 and 14. Ensures workability. In the example shown in FIG. 4, not only the bolt 14 is not exposed to the outside and the appearance is excellent, but the skylight panel 2 is not directly attached to the opening frame body 11 by a bolt, so that a local force is applied to the skylight panel 2. The bolt tightening force does not act, and the right horizontal piece 11d of the upper frame 11a and the lower horizontal piece 13c of the panel mounting frame 13 act equally to prevent the skylight panel 2 from being damaged or deformed.

[0012]

[Problems to be solved by the device]

 However, the conventional panel mounting structure for the daylighting skylight still has the following common problems. That is, the first point is that the bolting work must be performed in the narrow space portion formed in the rising portions of the opening frame members 1 and 11.

The second is particularly important, but as described above, in the recent daylighting skylight device, the skylight main body is enlarged, and a plurality of panels are often connected to one skylight and used. The connecting part is generally a structure in which the ends of the panels are overlapped and connected via an adhesive sealant, and the connecting part extends to the flange part of the skylight panel 2. Therefore, even in the panel mounting portion to the opening frame bodies 1 and 11, there is a portion where the two flanges of the panel 2 locally overlap.

By the way, in the case of the above-mentioned conventional example shown in FIG. 3, the panel 2 which is easily deformed by the bolts and nuts is fixed to the opening frame bodies 1 and 11 which are rigid bodies at a plurality of positions by interposing a plurality of packings. It will be. At this time, since it is difficult to fix all the fixed parts with equal force, the amount of deformation of the packing and the panel in each fixed part is different, and they are misaligned and the bolt insertion holes of each fixed part are aligned. Disappear. In particular, in the above-mentioned two-ply overlapping part, a large deviation occurs compared to other fixed parts, making it difficult to insert the bolts. Even if the bolts can be inserted, a large tightening is required during the fixing operation compared to other fixed parts. It is necessary to tighten the bolts with an applied force to greatly deform them, and the panel 2 is easily damaged.

On the other hand, in the conventional example shown in FIG. 4, since the horizontal portion 13 a of the panel mounting frame 13 uniformly presses and fixes the open end of the opening frame 11 over the entire circumference of the panel 2, a single panel 2 is used. In this case, although the above-mentioned function is fully exerted, when a plurality of panels 2 are connected and used, the pressing force is different between the two-ply overlapping part and the one-ply part, and in terms of airtightness and watertightness. Inconvenience is likely to occur and it is necessary to take separate measures for that.

The present invention has been made in order to solve the problems of the prior art, and provides flexibility to the fixed portion of the panel to ensure workability and to sufficiently perform the above-mentioned various functions. The purpose is to develop a skylight panel mounting structure that can be demonstrated.

[0017]

[Means for Solving the Problems]

 As a means for achieving this object, the present invention provides a mounting structure for mounting a dome-shaped skylight panel to a skylight opening frame through a mounting bracket, which has a mounting flange at a peripheral mounting portion. The panel mounting portion of the opening frame has a mounting mounting surface for the mounting flange, and the outer peripheral surface of the panel mounting portion is provided with multiple positioning grooves extending parallel to the mounting mounting surface. A plurality of screw screw holes are formed at predetermined intervals in the forming portion of the positioning groove, and the fitting is made of a first metal piece having at least a predetermined length. The metal piece is an opening frame fixing portion having a large number of fitting projections fitted in the positioning grooves formed on the outer peripheral surface of the panel mounting portion and a screw insertion long hole extending in a direction orthogonal to the fitting projections. Press the flange of the above skylight panel to press the flange. When the second metal piece is used in addition to the first metal piece, the bent metal piece has an L-shaped cross section and has the same length as the first metal piece. And a plate member having cover engaging pieces on both side edges in the longitudinal direction and having long screw insertion slots formed in the longitudinal direction at positions corresponding to the screw insertion slots of the first metal piece. Use as a piece.
