Description

[Detailed Description of the Invention] The present invention has a simple configuration, can be easily and quickly installed at the eaves of a curved roof on site, and can firmly support the eaves. This invention relates to a base frame for the eaves of a curved roof whose general part (middle part) can be adapted to any type of roof with 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 connection will be troublesome and the construction cost will be relatively high. This is intended to improve the drawback that rainwater easily enters from there, causing a leakage phenomenon.

However, there is no supporting material that can relatively firmly support the eaves of a 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 body made of metal plate, which is approximately fan-shaped when viewed from the side. A curved roof part that can sufficiently withstand the roof load is formed by press working, or in the above structure, a separate piece of roof roof is fixed so as to be continuous with the upper part of the curved roof part. As a result, the structure is simple, and it can be installed easily and quickly on the eaves of a curved roof at the site, and the eaves can be strongly supported, which solves the above problems and achieves the purpose. To provide a roof which can be adapted to any roof with a general part having an appropriate slope.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Δ is a base frame for the eaves, and the base frame main body 1 made of a metal plate is approximately fan-shaped when viewed from the side, and the substantially arc-shaped oblique side thereof is bent to an appropriate width so as to be able to sufficiently withstand the roof load. 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-mentioned structure, a separate metal tarpaulin piece 3 that is continuous with the upper part of the curved tarpaulin portion 2 is fixed to one side of the base frame body 1 (see Fig. 3).
(See Figures 7 and 9). The metal cover piece 3 is formed to have an appropriate slope depending on the slope of the roof.

A part or the whole of the curved tally part 2 in the longitudinal direction is bent as a curved part 2A. That is, in the case of a curved tally part 2 in which a part of the longitudinal force direction is curved to an appropriate curvature (see FIGS. 7, 13, 14, etc.),

This curved tarp portion 2 is not limited to the cross-sectional shape shown in the drawings as long as it has sufficient strength and can be placed. Furthermore, although the cross section of the cover piece 3 has a U-shaped cross section, it is not limited to this as long as it can be made to extend continuously to the curved cover part 2. 1a is a mounting piece provided integrally or separately around the base frame main body 1, 1b is a reinforcing rib, and 1c is a hole.

The eaves base frame A is attached to existing pillars 4, rims 5, rafters 6, etc. near the eaves of a structure (such as a house) at the site. In the embodiment, the mounting piece 1a of the base frame A for the eaves is attached to the pillar 4, the rim 5, etc. with a nail. It is fixed with screws, etc., and the above water side end of the taruki piece 3 is nailed to the existing rafter 6, etc., as necessary.

Intermediate arcuate bulges 7f, 7f are formed in the respective portions. Further, when viewed from the side, a part or the whole of the longitudinal direction is curved to an appropriate curvature to form the curved building board 7. That is, in the case of a curved building board 7 in which a part of the longitudinal direction is curved to an appropriate curvature, it is formed of a bent part and a straight part like the curved tally part 2. There is. In addition, in the case of a curved construction board 7 whose entire length in the longitudinal direction is curved to an appropriate curvature, although not shown,

Of course, the invention is not limited to the embodiment shown in the drawings as long as the part or the whole is curved to an appropriate curvature. In the figure, 12 is a beam material, 13 is a main house, 14 is an eaves edge material, 15 is an eave top board, 16 is an eave roof cut material, and 17 is a wall material.

Next, the effects will be explained.

First, in the invention as claimed in claim 1, the substantially arcuate extended oblique side of the base frame main body 1 made of metal plate, which is substantially fan-shaped when viewed from the side, is appropriately bent so as to be able 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 easily and quickly installed at the eaves of the curved roof B on site. The eaves of the curved roof B can be supported relatively firmly, and thirdly, it can be adapted to any general part of the roof with an appropriate slope.

To explain these points in detail, conventionally there were wooden rafters 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. However, even on one site (roof), there are many rafters, and it takes a lot of skill to make them have a certain curvature, which is extremely inefficient. Although it had drawbacks such as weakening in strength due to stress concentration,
In the present invention, by forming the curved Kuruki part 2 on the lower mountain frame main body l, which serves as the reinforcing part, by press working,
The curved curvature can be made to a constant curvature with high precision without having to be made each time according to the site, and the curvature can be easily processed, so that the base frame main body 1 and the curved curved part 2 are -
Because it is a solid body, the section modulus can also be made large and strong. Furthermore, the eave part of the roof has a wind force coefficient several times higher than that of the general part of the roof in terms of architectural engineering.In particular, in the present invention, the lower pond frame main body 1 is physically formed on the curved tarp part 2. As a result, the base frame main body 1 becomes a force aggregate, and the wind force coefficient of the former tip increases significantly by L, 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, which is extremely efficient, and the construction time can be shortened, making the construction troublesome. Curved roof B
This has the advantage of reducing overall costs. Furthermore, since the base frame A for the eaves is mass-produced in a factory, it can be made at low cost.

Furthermore, even if the roof slope of the general part of the curved roof B is appropriately configured to be different as shown by the dotted lines in FIGS. 13 and 14, in the present invention, the curved roof part 2 does not reach this general part. Can adapt to all roof slopes. This has great advantages in terms of inventory management, ease of construction, and ease of handling.

Next, in the invention of claim 2, in contrast to the structure of the first aspect of the invention, a separate member piece 3 is fixed so as to be continuous with the upper part of the curved curving part 2. Firstly, the eaves of the curved roof Y3 can be more strongly supported, and secondly, by fixing the metal kuruki pieces 3 to the general part of the roof at an appropriate slope at the factory, the overall structure can be improved. It has the advantage of being adaptable to all types of 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. The range of applications can be expanded by fixing the tarp pieces 3 at the factory in accordance with the roof slope of the site. In addition, by making the taruki piece 3, which has a small number of parts, as a separate material, it is possible to improve the efficiency of use of parts, with less metal plate material than the base frame 8 for eaves, in which even the taruki piece 3 is integrated. Can be manufactured. The other configurations are the same as those of the first aspect of the invention, and the same effects can be achieved.

In addition, the one shown in FIG. 18 is also a curved roof B @flip, in which the bending point at the upper part of the roof is formed in a curved shape with a relatively large radius of curvature. The part is simply steeply sloped, and this includes the 19th
An eaves base frame A is used in which a linear tally part I8 as shown in the figure is integrally formed with the base frame main body 1. Even in this case, the I1 river effect is almost the same as in the above invention. Furthermore, although the base frame A for the old end of the present invention is made of a metal plate, it is of course possible to use a synthetic resin as long as it has sufficient strength.
