Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a simple structure, can be easily and quickly installed at the eaves of a curved roof on site, can firmly support the eaves, and can be installed on the general part of the roof. This invention relates to a base frame for the eaves of a curved roof that can be adapted to any type of roof whose (middle part) has an appropriate slope.

Recently, in general houses, factories, gymnasiums, etc., there has been active research and development on roofs in which even the eaves of the roof are formed into a curved shape and are formed integrally with the general part of the roof. This is mainly due to the fact that if only the eaves end is connected using a separate member, the construction of this joint will be troublesome and the construction cost will be relatively high. This is to improve the problem that rainwater easily enters through the pipes, causing leakage.

However, there is no supporting material that can relatively firmly support the eaves of the curved roof, has a particularly simple structure, and can be easily and quickly installed at the eaves. The purpose is to

Therefore, as a result of extensive research in order to eliminate the above-mentioned drawbacks, the applicant has developed the present invention by suitably bending the generally arc-shaped inclined sides of the base frame main body made of metal plate, which is approximately fan-shaped when viewed from the side. A curved tarpaulin part is made to be able to sufficiently withstand the roof load, and the whole is formed by press working, or in the above structure, a piece of tarpaulin of another member is fixed so as to be continuous with the upper part of the curved tarpaulin part. This makes configuration easy and
It can be easily and quickly installed on the eaves of a curved roof at the site, and can firmly support the eaves, solving the problems mentioned above and achieving the purpose. To provide a general part that can be adapted to any suitable slope.

It is formed as a curved tally part 2, and the whole is previously formed by press working in a factory (see FIGS. 1, 5, 11, etc.). Alternatively, in the above structure, a separate metal tarp piece 3 that is continuous with the upper part of the curved tarp portion 2 is fixed to one side of the base frame main body 1 (Figs. 3 and 7).

There are multiple embodiments of this curved roof B, and the curved roof B of the first embodiment is shown in FIG.
As shown in FIG.

The hanger 9 is placed on a base material 8 such as a curved roofing board or a heat insulation board at appropriate intervals, and a hanger 9 is locked to the lower part 7c of the curved building board 7. The bottom part of 9 is fixed to the base material 8 etc., and then the upper part 7b of the adjacent curved building board 7 is fitted onto the lower part 7c of the front curved building board 7 and the hanger 9. , the upper part 7b is bent and tightened, and the cross section has an inverted L shape (see Fig. 2 and Fig. 15), and the cross section is omitted.

is wall material.

Next, the effects will be explained.

First, in the invention as claimed in claim 1, the substantially arc-shaped inclined sides of the base material frame main body 1 made of a metal plate, which is substantially fan-shaped when viewed from the side, are appropriately bent so as to sufficiently withstand the roof load. By forming the entire curved roof part 2 by press working, firstly, the structure is simple, and it can be installed easily and quickly at the eaves of the curved roof B on site.
Secondly, the eaves of the curved roof B can be supported relatively firmly, and thirdly, it can be adapted to any slope of the general part of the roof.

To explain these points in detail, in the past there were wooden rafters that were made on-site by making cuts with a saw etc. and making multiple cuts at appropriate intervals to form a curve to the desired curvature. There are many rafters on a single site (roof), and it not only takes skill to make them have a certain curvature, but it is also extremely inefficient. However, in the present invention, by forming the curved tally part 2 by press working on the base frame main body 1, which serves as a reinforcing part, the curvature of the curved part is reduced. It is possible to achieve a constant curvature with high precision without having to make it each time according to the site, and the curvature can be easily processed. The coefficient can also be made larger and stronger. Furthermore, the wind force coefficient of the eave part of the roof is several times higher than that of the general part of the roof in terms of architectural engineering. As a result, the base frame main body 1 becomes a force aggregate, and the wind force coefficient at the eaves increases significantly, making it possible to sufficiently withstand this strength. In addition, the eaves base frame A can be brought to the site and attached to the eaves without requiring any skills, making the construction extremely efficient, and in turn reducing the number of construction days. This has the advantage of reducing the construction cost of the entire shaped roof B. Furthermore, since the base frame A for the eaves is mass-produced in a factory, it can be made at low cost.

Also, the roof slope of the general part of the curved roof B is
Even if the structure is suitably different as shown by the dotted lines in the figures and FIG. 14, in the present invention, the curved tally part 2 does not reach this general part, so it can be adapted to all roof slopes. This is important from the perspective of inventory management, ease of construction,
This is an extremely advantageous advantage in terms of ease of handling.

Next, in the invention according to claim 2, in contrast to the structure of the invention according to claim 1, a separate member 3 is fixed so as to be continuous with the upper part of the curved diaphragm part 2. Firstly, the eaves of the curved roof B can be more strongly supported, and secondly, by fixing the metal talcum pieces 3 in accordance with the appropriate slope of the general part of the roof at the factory, all It has the advantage of being compatible with roofs.

This allows almost the entire lower surface of the eaves of the roof to be supported, increasing the strength of the eaves where the wind force coefficient is several times greater. By fixing the piece 3, the range of applications can be expanded. or,
By using a separate material for the tarp piece 3, which has a small amount of parts, we have created an eave base frame A that integrates the tarp piece 3 as well.
Since fewer metal plates are required, the efficiency of member utilization can be increased, and the product can be manufactured at a lower cost. The other configurations are the same as those in the first aspect of the invention, and the same effects can be achieved.

The roof shown in Fig. 18 is also in the category of curved roof B, as the bent portion at the top of the roof is formed into a curved shape with a relatively large radius of curvature, but in this case, the eaves end is curved. It simply has a steep slope, which includes a straight talc section 1 as shown in Figure 19.
An eave base base frame A in which 8 is integrally formed with the base frame body 1 is used. Even in this case, the effect is almost the same as that of the above invention. Moreover, the foundation frame A for the eaves of the present invention
Although it is made of a metal plate, it is of course possible to use a synthetic resin as long as it has sufficient strength.
