Description

[Detailed description of the invention] (Technical field) The present invention relates to a roofing structure using, for example, long roofing materials. The above relates to a roofing structure to which the tip of the roofing material located at the upper level is attached.

(Prior art) As shown in the partially omitted side view of FIG. 3, a roofing structure using long roofing materials is constructed by stretching a necessary roofing material 20 on a roof structure material 10, and On the material 20, crosspieces 21, 21, . . . are laid out in a state perpendicular to the roof inclination direction. Then, the rear part 31b of the roofing material 31 located at the lower level is covered and nailed onto the crosspiece 21. Next, the tip portion 32a of the roof material 32 located at the upper level is placed over and hung. In the same manner, roofing materials 33, 34... (none of which are shown) are sequentially covered from the eaves toward the ridge.

(Problems with the conventional technology) In such a roofing structure, the crosspieces 21, 21, etc. are arranged on the roofing material 20 in advance, so there may be cases where the plane of the roof structural material 10 lacks precision, or the crosspieces 21, 21... If an error in the allocation of 21 occurs, the error must be adjusted at the tip and rear hooking parts of each roofing material. For this reason, even if the tip and rear parts of the roofing material are formed in advance in a factory, etc., the construction becomes complicated, as it is necessary to modify the tip and rear parts again on site, and furthermore, it is necessary to perform rain protection treatment at the hanging parts. This is causing problems such as complexity.

(Means for solving the problem) In order to solve the above problem, the present invention nails a crosspiece to the rear of the roofing material located at the lower level, and attaches the tip of the roofing material located at the upper level to the crosspiece. It is attached in a covered state.

(Operation) In other words, the position of the roofing material located at the lower level is determined in advance, the position of that position and the position of the roofing material located at the upper level are temporarily determined, and the overlapping length of the attached part is adjusted to create the roof located at the lower level. Nail the crosspiece from above the rear of the timber. The tip of the upper roofing material is then nailed onto this crosspiece so as to cover it. Therefore, the crosspieces are not allocated on the roofing material in advance, but are nailed down one after another according to the roofing material, so it becomes possible to easily adjust allocation errors, etc. on site.

(Example) Hereinafter, the roofing structure of the present invention will be explained in detail based on the drawings.

FIGS. 1 and 2 are partially omitted cross-sectional views illustrating the construction procedure.

The roof structural material 1 consists of rafters 11 and sheathing boards 12 stretched over their upper surfaces, and roofing materials 13 of a required thickness are laid on the sheathing boards 12 as required. Roofing material is then covered on this roofing material 13 from the tip of the eaves (not shown) to the roof ridge (not shown). Usually, as the roofing materials 2, 4, and 6, galvanized long iron plates, colored long iron plates, or corrugated iron plates are used. These roofing materials 2, 4, and 6 have a required body length, tip portions 2a, 4a, and 6a with the lower portion of the body length bent downward, and the tip portion 2.
Rear part 2 raised at approximately the same height as a, 4a, and 6a
b, 4b, and 6b, respectively.

Although not shown because it is similar to conventional roofing construction, first, the tip of the roofing material 2 is aligned with the arabesque at the tip of the eaves. Then, the rear part 2b is attached to the roofing material 13.
Place it on top. Place the crosspiece 3 on this rear part 2b,
After adjusting the positional relationship between the roofing materials 2 and 4 by placing the tip 4a of the upper roofing material 4 over the crosspiece 3, attach the crosspiece 3 from above the roofing material 2 onto the roof board 12 with nails _N1 . It sticks. Next, the upper roofing material 4 is finally positioned, and its tip 4a is hooked to the crosspiece 3 and nailed with nails _N2 .

That is, since the rear part 2b of the roofing material 2 and the tip end 4a of the upper roofing material 4 are approximately the same height, the crosspiece 3 having approximately the same height can be reliably held. Furthermore, it is possible to adjust the overlapping length L to a required amount in advance before nailing the crosspieces 3.

Similarly, the crosspiece 5 is arranged on the rear part 4b of the roofing material 4, and the tip part 6a of the roofing material 6 located in the upper row is placed on the crosspiece 5 to adjust the position of both roofing materials, that is, the required overlap length L With this secured, the crosspieces 5 are nailed to the roof board 12 with nails _N3 . Then, the tip 6a of the roofing material 6 is placed over the crosspiece 5 and nailed to the crosspiece 5 with nails _N4 .

The above construction will be carried out one after another until the roofing material is laid down to the ridge. As in the past, in the ridge section, although not shown, wrap plates made of the same material as the roofing material are provided on the fan plate and the ridge plate to completely keep out the rain.

(Effects) The roofing structure described above has the following remarkable effects.

During construction, the overlapping length of the roofing materials can be adjusted appropriately, so there is no need to adjust the roofing materials on site, and roofing construction with extremely high construction efficiency can be provided.

Since the overlapping length of the roofing materials can be appropriately secured in consideration of the roof slope, etc., on-site rain protection construction is extremely reliable.

In particular, when corrugated iron plates are used as roofing materials, gaps are formed between the corrugated iron plates and the roofing material, extending all the way to the eaves. It flows down inside and is discharged.
