[Conventional technology]

Conventionally, as a skylight device in the roof structure of this kind of building, various structures have been proposed, and most of them have a roof structure structure that constitutes a skeleton part of the roof structure. A roof window device of an open / close type or a dead-end type assembled into a unit in advance is attached to a mounting space portion selectively cut off in a part of the roof portion.

6 (a) and 6 (b) schematically show an installation state of the skylight device in this type of thatched roof structure according to a conventional example. FIG. 1A is a vertical cross-sectional explanatory view of the conventional example structure, and FIG. 1B is a plan explanatory view thereof.

In the configuration of each of these conventional examples, reference numeral (A) indicates a roof construction structure in a building, and reference numeral (B) indicates a lateral thatched roof structure that is raised on the roof construction structure (A). Further, reference numeral (C) is the side-roof structure (B).
2 shows a mounting space portion formed by selectively omitting a part of the above, and reference numeral (D) is a skylight device assembled in advance into a unit to be mounted in this mounting space portion (C).

In the case of this conventional example structure, the roof construction structure (A) has a plurality of main building materials (11) made of lightweight steel such as C-section steel arranged in parallel with the roof ridge direction or the eaves direction on the roof roof construction. Further, they are arranged and fixed at predetermined intervals in the vertical direction along the roof slope.

Further, on each of these purlins (11), a plurality of flanged channel steels, that is, a plurality of lumber (1
2) is erected and fixed perpendicularly to each main building material (11) at predetermined left and right intervals.

In addition, the horizontal roof structure (B) that is raised on the roof structure (A) is a long horizontal thatched roof plate (13) such as a galvanized steel plate formed into a desired transverse sectional shape. ) Is used to engage and connect a plurality of the thatched roof boards (13) between vertically adjacent ones on the above-mentioned each lumber (12), and by a hanging member (not shown) or the like,
It is properly held and set aside.

In the above case, each lumber (12) is placed on each main building material (11).
Also, each thatched roof plate (13) on each hanging wood (12),
Although they are each directly fixed, they may not be directly fixed together, but may be fixed indirectly through a base material such as a wooden wool board,
Here, for the sake of explanation, it is shown that they are directly fixed.

In this manner, the thatched roof structure (B) is raised on the roof construction structure (A), or before the respective thatched roof boards (13) are raised on the above-mentioned rafters (12), Mounting space (C) between each hanging lumber (12) on each purlin (11)
Is set. Then, the roofing of each side thatched roof plate (13) is excluded only for this installation space (C), and the side thatched roof plate (1) is set in this installation space (C).
Along with the roofing of 3), the skylight device (D) assembled into a unit beforehand is installed. In this way, the desired skylight structure with a thatched roof is obtained.

Many of them are of a structural type in which a glass plate is held in the window frame.

In addition, Japanese Utility Model Publication No. 63-152823 or Japanese Utility Model Publication No. 61-13
Background structures such as skylights disclosed in Japanese Patent No. 3626 are also known.

[Problems to be Solved by the Invention]

However, in the case of the conventional skylight structure with a thatched roof shown in FIGS. 6 (a) and 6 (b), there are the following problems.

That is, the first problem is that the arrangement pitch Ap (the center-to-center reference dimension is 750 mm between the centers) of the respective roofing materials (11) in the roof structure (A) provided in parallel with the ridge direction or the eaves direction.
And the roofing pitch Bp (standard working width of 240m) of each thatched roof plate (13) in the thatched roof structure (B)
m is about), and do not necessarily correspond to each other, and in many cases are not related to each other.

Moreover, depending on the form of the roof, horizontal roofing boards (13) with different working widths are adopted, and the length Dl of the roofing direction corresponding to each pitch of the skylight device (D) assembled as a unit. However, usually, the number of the thatched roof boards (13) used at that time is doubled. In other words, it is intended that the horizontal roofing board (13) fits snugly within a predetermined number of sheets, and for this reason, FIG. 6 (a),
As shown in (b), there is a possibility that the purlin material (11) may be present immediately below the installation position of the skylight device (D), and the edging of the skylight device (D) from the inside is expected. It was something I could not leave.

The second problem is that the construction work has been divided into specialized fields, and at present, the roof structure using steel (A).
Is contracted to a steel frame contractor, a horizontal roof structure (B) using a steel plate thatched roof plate is contracted to the roofer, and a skylight device (D) using a sash member is contracted to the sash contractor. There is little flexibility between. For this reason, the skylight device (D) corresponding to the thatched roof structure (B), which is generally premised on the site, cannot be quickly and relatively mounted accurately, and the inconvenience described above is not improved. There was a problem.

In Japanese Utility Model Laid-Open No. 63-152823, the upper and lower purlins are connected by a pair of receiving beams facing each other, and a skylight base is provided in a rectangular space formed between the upper and lower purlins and the receiving beams. Although a skylight foundation structure is disclosed in which a frame is provided and the end of the middle purlin between the upper and lower purlins is joined to the receiving beam, the vertical and horizontal dimensions of the skylight foundation frame are adjusted according to the dimensions of the skylight itself. Therefore, it was necessary to attach accessories such as a drainage plate when installing the skylight in the gap between the roof and the skylight to perform rain proofing.

Further, Japanese Utility Model Laid-Open No. 61-133626 discloses the construction of a cross frame in a daylight roof. In this structure, the frame that serves as a base material for raising the transparent roof tile material is a combination of two crossbars and five horizontal crosspieces, as shown in FIG.
This is a structure in which this is fixed from the side of the pier by a pier receiving material, and a transparent roof tile material is screwed to this horizontal pier. Therefore, in the frame that is composed of the piers, etc., which correspond to the horizontal and vertical bars,
The technical idea of adjusting the mounting position and the size according to the size of the transparent roof tile is not disclosed at all.

The present invention is intended to solve the above-mentioned conventional problems, and an object thereof is to set a mounting space portion corresponding to a size of a skylight device when the skylight device is mounted on a horizontal thatched roof. Accurate and easy
