Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a face plate joint attachment device for metal roofs, and more specifically, for horizontal roofs using metal thin steel sheets, particularly for metal roofs with a descending roof structure. This relates to a device for attaching the face plate joint of the ridge.

[Conventional technology]

The roof of a building that has a descending ridge applied to a part of the roof structure, such as a so-called hipped structure, is
As shown in Fig. 3, descending ridges C are derived from both ends of ridge B on roof A, convex toward each eave at a predetermined angle θ selected from time to time. When applying a horizontal roofing structure using a horizontal roof made of metal thin steel plates to such a descending roof A, in contrast to a general gable roof,
Unlike when applying a horizontal roofing structure using horizontal roofing sheets of the same type, in addition to making the longitudinal engagement portions of horizontal roofing sheets parallel to each other on the ridge B side,
It is also necessary to intersect the ends of the same horizontal roof board at the angle θ with respect to the descending ridge portion C side.

FIGS. 4 to 8 show different conventional examples in which a horizontal roofing structure using horizontal roofing plates made of metal thin steel plates is applied to the descending ridge roof.

FIGS. 4, 5, 6, and 7 schematically show the general structure of the first and second conventional structures.
A cross-sectional view along the line, and FIG. 8 is a perspective view showing a part of the external appearance of the third conventional structure.

In each of these figures, numerals 1 and 2 are the roof surfaces of one side and the other side that are adjacent to each other with the ridge in between, and 1a and 2a are the roof surfaces of these roof surfaces that constitute the roof structure in the direction of the ridge. A plurality of purlin materials arranged at predetermined intervals parallel to each other or their arrangement lines, 1b and 2b are a plurality of vertical roofs hung vertically from the ridge side to the eave side at predetermined intervals on each of these purlin materials. This is the wood or its placement line, and 3-3 is the placement line of the descending ridge.

In addition, 4 and 5 are each of the rafters 1
b, 2b, is horizontally roofed from the ridge side to the eaves side in parallel to the ridge B, and is a horizontally roofed roof board made of metal thin steel sheets that constitutes each roof surface 1, 2. As is well known, the horizontal roof panels 4 and 5 on each roof surface 1 and 2 are formed by molded portions 4a and 5 formed on the respective longitudinal side surfaces.
a are engaged and connected to each other, and both extreme ends 4b and 5b are cut to correspond to the angle θ.

However, in the case of the first conventional structure shown in FIGS. 4 and 5, the eaves are placed on the rafters 1b and 2b whose ends are butted against each other along the down ridge arrangement line 3. A sacrificial board 6 for installation is fixed sequentially from the side, and both extreme ends 4b, 5b of each horizontal roofing board 4, 5 are individually fixed to this sacrificial board 6 for each horizontal roofing row. At the same time, both extreme ends 4
Similarly, on the sacrificial board 6 into which the ridges b and 5b are fitted, the lower ridge covers 7 are fitted and engaged individually for each row of horizontal roofing, and the roof is gradually raised toward the ridge side. .

In addition, in the case of the second conventional structure shown in FIGS. 6 and 7, waste boards 6 are sequentially interposed as necessary, and both ends of each horizontal roof board 4, 5 are The end portions 4b and 5b are individually rolled and engaged with each other for each horizontal roofing row, and the down ridge cover 7 is similarly individually attached for each horizontal roofing row on these mutually engaged portions. The covering is fixed and the roof is gradually raised.

Furthermore, as in the third conventional structure shown in FIG. On the other hand, both extreme ends 4b and 5b of each horizontal roofing board 4 and 5 are brought into contact with each other in a downwardly bent state, and each of these butt parts is sealed with a sealing material as appropriate. Depending on the situation, the roof may be gradually raised.

[Problem that the invention seeks to solve]

However, in the case of each of the conventional structures constructed as described above, the roofing work must be carried out on a roof frame with poor scaffolding.
Not only are they extremely difficult to work with, but they also have structural defects that make it extremely difficult to completely shut off the rain, and they tend to leak easily.In addition, the exterior design of the entire descending ridge section is also poor. , and also the first
In the case of the conventional structure, even if it is possible to raise the roof from the eave side to the ridge side, conversely, the intervening waste boards get in the way of raising the roof from the ridge side to the eave side. Furthermore, in the case of the structure of the third embodiment, since the descending ridge covers are simply arranged sequentially on the arrangement line of the descending ridges, the connecting parts between the descending ridge covers, and This method has various undesirable problems, such as the fact that the two ends of each horizontal roof plate are not completely connected to each other.

Therefore, the object of the present invention is to provide a metal roof of a descending structure using metal thin steel plates,
To provide a face plate joint attachment device for metal roofs of this type, which can achieve good roofing workability and reliable rain protection without being restricted by the roofing direction, and has an excellent external design. .
