Traditionally, the method of raining off the two-story part of a general house largely depends on the discretion of the workers at the site. Patent Documents 1 to 3 standardize the rain-sealing structure so that rain-sealing can be performed without depending on the experience of the worker. However, even if the external structure is constructed on the roof, the construction location, constituent members, size, etc. of the two-story part of the house, the lighting window, the roof hatch, etc. are different. For example, a two-story part of a house has through pillars, studs, pipe pillars, etc., and is an external structure of a size that humans can live in. It is a small external structure and does not require a beam. Further, the roof hatch is an external structure that allows humans to pass through and does not have through columns, studs, pipe columns, etc., but is generally arranged by being locked to a receiving beam or a purlin. Therefore, assuming an earthquake, for example, in the two-story part of a general house, it is assumed that the first floor part and the second floor part vibrate in series via through pillars, etc., while the light-collecting window is a partial structure of the roof. It is supposed to vibrate integrally with the roof. On the other hand, a roof hatch without through columns may propagate vibrations separately to the roof and the roof hatch. Therefore, there is a need for a rain-fed structure suitable for external structures that do not have through columns.

Further, if the rain closing structure can be standardized, the rain closing can be performed without depending on the proficiency level of the worker. Further, if a part of the pre-standardized rain closing structure is fixed to the roof hatch, the rain closing work can be performed more easily. Therefore, it is desired to develop a roof hatch suitable for rain-sealing and a roof hatch kit including a rain-sealing structure.

As the fixing member (30), each of the above parts may be used as an individual component, or at least two or more of each part may be integrally formed. Further, as for the fixing member (30), the gap portion (31), the waterproof case holding portion (33), the waterproof case cover mounting portion (35), and the waterproof case cover portion (37) are provided for each of the outer peripheral plates (5). ) May be used to fix the strip-shaped portion (21) of the waterproof case (20). An example of a member in which a gap portion (31), a waterproof case holding portion (33), and a waterproof case cover mounting portion (35) are integrally formed with one outer peripheral plate (5) as a unit is fixed to FIG. 3 (B). It is shown as a member A (30A). When the waterproof case cover portion (37) is fixed to the fixing member A (30A), it can be used as the fixing member (30). In FIG. 3A, on the outside of any one of the outer peripheral plates (5), a gap portion (31), a waterproof case holding portion (33), a waterproof case cover mounting portion (35), and a waterproof case cover portion are shown. The partial perspective view explaining the mounting order in the case of fixing (37) is shown. Further, FIG. 3B shows an embodiment in which the fixing member A (30A) is fixed to the outer peripheral plate (5) and the waterproof case cover portion (37) is fixed to the fixing member A (30A). Note that FIG. 3C is an exploded vertical sectional view of FIG. 3B. A nut (5a) is fixed in advance to the inner wall side of the outer peripheral plate (5) of the roof hatch A (10A). Further, a bolt hole (39') is formed in advance in the fixing member A (30A). Therefore, the fixing member A (30A) can be fixed to the outer peripheral plate (5) by inserting the bolt (39). Next, the waterproof case cover portion (37) is fixed to the waterproof case cover mounting portion (35) of the fixing member A (30A) with a bolt (39) or the like.

As shown in FIG. 3A, the gap portion (31) constituting the fixing member (30) has a total length that goes around the outer peripheral plate (5) of the roof hatch A (10A), and the outer peripheral plate (5). It is arranged between the waterproof case holding portion (33) and the waterproof case holding portion (33). As will be described later, after the waterproof case (20) is attached to the outer periphery of the roof hatch A (10A) fixed to the roof surface, the waterproof case (20) is loosely fitted by the fixing member (30). In the present invention, since the gap portion (31) is fixed to the upper part of the strip-shaped portion (21) of the waterproof case (20), the gap portion (31) to be used has a predetermined thickness that allows the waterproof case (20) to be loosely fitted. Has (t1). The thickness (t1) takes into consideration the thickness of the strip-shaped portion (21), the thickness of the waterproof paper (53) that can be arbitrarily arranged between the outer peripheral plate (5) and the strip-shaped portion (21), the number of stacked sheets, and the like. Can be decided. The shape of the gap portion (31) is preferably a long plate-like object in order to uniformly secure a predetermined thickness (t1), but is not limited to this. Further, FIG. 3D shows an example in which the corner portions of the outer peripheral plate (5) are connected by two gap portions (31) along the outer peripheral plate (5). As shown in the figure, if the length of one side of the gap portion (31) is made longer by the thickness of the gap portion (31), the corner portions can be brought into close contact with each other without a gap. A waterproof material (40) such as a waterproof tape may be attached to the corner portion in the same manner as the connecting portion (22) of the strip-shaped portion (21) shown in FIG. 2 (B). The same applies to the waterproof case holding portion (33) and the waterproof case cover portion (37), which will be described later. The gap portion (31) may be prepared by forming one plate material into corner portions corresponding to the four corner portions of the outer peripheral plate (5).

It is possible to prevent the strip-shaped portion (21) from deteriorating by fitting and blocking external wind and rain. For this purpose, the shape of the waterproof case retainer (33) is a long plate-like object having a length substantially equal to that of the gap (31), but wider than the gap (31), that is, the upper end. When aligned with the upper end of the gap portion (31), it is preferable that the lower end is wider so that the lower end can be closer to the vicinity of the roof surface than the gap portion (31). The degree can be appropriately calculated from the height from the roof surface to the upper end of the gap (31). As a result, it is possible to prevent rainwater from rebounding from the lower end of the waterproof case holding portion (33) and efficiently prevent deterioration of the waterproof case (20). Further, similarly to the gap member (31), it may be composed of a plurality of waterproof case holding portions (33) along each outer peripheral plate (5), and corresponds to four corner portions of the outer peripheral plate (5). It may be a single waterproof case holding portion (33) having a corner portion formed therein. In the case of a plurality of sheets, if the length of one side of the waterproof case holding portion (33) is made longer by the thickness of the waterproof case holding portion (33) as in the gap portion (31), there will be no gaps. The parts can be brought into close contact with each other. A waterproof material (40) such as a waterproof tape may be attached to the connected corners. In the present invention, it is preferable to attach a cap (33a) capable of forming a convex portion protruding toward the gap portion (31) to the lower end portion of the waterproof case holding portion (33). The cap (33a) can more effectively prevent rainwater from entering the band-shaped portion (21) side from the lower end of the waterproof case holding portion (33).

The waterproof case cover mounting portion (35) is a member for fixing the waterproof case cover portion (37). The waterproof case cover portion (37) is a member that covers at least the upper portion of the flange (23) constituting the waterproof case (20) and the end portion of the roofing material.
