Abstract

PURPOSE:To obtain a hip roof with high load resistance by placing a field panel constituted of a proper combination of a triangle field panel and trapezoid field panel on inclined beams mounted from the ends of a ridge-beam and forming a flat side inclination section and a gable side inclination section. CONSTITUTION:A flat side inclination section 7 and a gable side inclination section 8 making their heights of the ends of a ridge-beam 3 are formed of a field panel 9 supported by inclined beams 4 and 5 mounted from the ends of the ridge-beam 3. The field panel 9 is constituted of a proper combination of a triangle field panel 10 equal to the flat side inclination section 7 in terms of dimension and shape and a trapezoid field panel 11 provided with an oblique side of the same angle of inclination as that of the triangle field panel 10. The field panel 9 adjacent to the flat inclination section 7 and the gable side inclination section 8 in the lateral direction is provided and fixed chevronwise. Accordingly, a hit roof 1 with high load resistance can be formed without using any bearing member, so that the lower space of the hip roof 1 can be effectively used.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hip roof device using field panels for buildings such as houses.

(Background technology) A hipped roof with sloped gable sides is used for roofs due to drainage of rainwater and good design. (basically the same), install two truss ridgepoles and ceiling joists reinforced in an M-shape, etc., and from this truss, install corner tall wood in each hipped corner (in each case, Two rafters were installed in the roof, a large number of supporting rafters were installed vertically at predetermined intervals on these corner timbers, and the roof was constructed by interposing fall prevention devices between these supporting rafters.

However, in this case, the reinforcing truss is essential because it supports the main load of the corner talus, and therefore, in a hipped roof, the attic must be partitioned off by the reinforcing truss.

Therefore, for example, when a living or storage space is installed in the attic with a roof slope of 45° to 60°, the roof must generally be of a gable type because the reinforcing truss separates the space. However, it is impossible or extremely difficult to convert this into a hipped roof.

In view of this point, the inventors of the present invention filed a patent application No. 62-2469 to develop a roof structure with a hipped roof that eliminates the partition by such trusses.
It has already been proposed in issue No. 45.

However, in this case, it is more suitable to construct the roof by field work, and while various parts of the building are being made into panels, efforts are still needed to make them into panels.

(Object of the Invention) An object of the present invention is to provide a hipped roof device that does not have any partitions in the attic.

(Structure of the Invention) In accordance with the object described in item 1, the present invention uses a predetermined outdoor field panel, and the support and fixation of the field panel is performed by three-way inclined beams, thereby eliminating the structure that serves as a partition. However, this field panel is further equipped with a triangular field panel and a plurality of trapezoidal field panels, and by selectively using these, the gable side slope can be arbitrarily set between the vertical gable panel. In other words, the present invention comprises a flat side inclined part partitioned into a right triangle and a gable side sloped part of an isosceles triangle, with the apex at the end position of the purlin, and these flat side inclined parts and the gable side sloped part. The sloping part is a triangular field panel or a trapezoidal field = 3-ground panel fixedly supported by a three-way inclined beam installed from the end of the ridgepole to form a T-shape on both flat sides and the center of the gable side. Therefore, the triangular field panel is configured in a right triangular shape so as to have the same size or similar shape as the flat sloped part,
The trapezoidal field panels each have a hypotenuse with the same angle of inclination as the triangular field panel, and are configured in a plurality of trapezoid shapes whose widths are gradually expanded in stages, and a triangular field panel of the same size is installed at each flat side slope. However, a triangular field panel and one or more trapezoidal field panels of similar shapes are mounted and fixed on one end on the slope beams on both the flat sides, and the gable side slope section has the same dimensions as the flat side slope section. A triangular field panel or a trapezoidal field panel is installed symmetrically with one end placed and fixed on the gable side central slope beam, and the horizontally adjacent field panels on the flat side slope and the gable side slope are The gist of this invention is a hipped roof device using field panels that are fixed in a sloping mountain shape.

The present invention will be described below with reference to drawings showing embodiments. The drawings show a building with an existing frame structure when its roof is removed and a roof with a living space is installed thereon. A case where the present invention is applied to a ridge portion is shown.

1 is a hipped roof, and this hipped roof 1 has a roof part 2 on the + side.
and a gable-side inclined portion 8 having an isosceles triangle shape with its apex at the end position of the ridgepole 3. The roof part 2 on the + side has a vertical dimension that matches the gable side slope part 8 set in stages at its end, and also has a flat side slope part of a right triangle whose apex is the end position of the ridgepole 3. 7
is set so as to be separated from other parts of the roof section 2.

At the end position of the ridgepole 3, the hipped roof 1 has inclined beams 4 and 5 facing in three directions installed between the ridgepole 3 and the ceiling joists 6 or between the gable panels 13 erected thereon. There is. That is, the inclined beams 4 and 5 are appropriately selected from 2 x 2 inches to 2 x 8 inches in consideration of the roof load, and two of each are used. On the sides, they are arranged in the direction of extension and inclination of the purlin 3, that is, in the center, so that they form a T-shape in plan.

This T-shaped three-way inclined beam 4°5 has
The field panel 9 supports the plane slope part 7 and the gable side slope part 8 to form a field.

The field panel 9 is composed of a triangular field panel 10 and a trapezoidal field panel 1 to be used for this, with the article side sloped part 7 as a reference.
1... and so on. At this time, the triangular field panel 10 is formed into a right-angled triangle having the same dimensions as the side inclined portion 7 or a right-angled triangle having a shape similar thereto, while the trapezoidal field panel 1
1... has a hypotenuse with the same inclination angle as the triangular field panel 10, forms a trapezoid with the other end vertical, and has a plurality of trapezoids whose widths are expanded in stages.

What is shown is that the triangular field panel 10 has a base of 910 meters and a height of 1198 m in the V shown in Fig. 3 (a), and the trapezoidal field panel 11... has its upper side aligned with the base of the triangular field panel 10, and its base is The height is 1198 layers based on the one that is twice the length of the 910 layer, and the height is 9 layers without changing.
A total of three types of products with 10 layers each will be used, with the lower side extended laterally to increase the width, and as shown in Figure 3 (
In b), the triangular field panel 10 has a base of 1,365 m and a height of 1,930 m, and the trapezoidal field panel 11- is 455 w for each trapezoidal field panel 11F shown in Fig. 3(a).
1 is added, and these are used as one set to constitute the flat side inclined part 7 and the gable side inclined part 8.

These field panels 9 are constructed by forming each frame 14 as shown in FIG. 2 with 2 x 4 inch structural members 15.
A 12-thick structural plywood 19 is stretched over this, and at this time, in the triangular field panel 10, the structural plywood 19 extends up to the lower intermediate material 18 position of the trapezoidal field panel 11.
..., the upper and lower intermediate members 17 and 18 are stretched, and the frame 14 of each field panel 9 is
In this case, the oblique side structural member 16 is installed so as to be inclined toward the back side of the structural plywood 19.

In addition, what is illustrated in FIG. 2(f) is a trapezoidal field panel 1.
This is a rectangular field panel 12 that is interposed between 1 and 11 and has a width of 910 mm and a height that matches the trapezoidal field panels 11 to adjust the width of the gable side slope.

These field panels 9 are appropriately selected and used depending on the installation state of the gable side slope section 8. That is, the gable side slope part 8 is installed by installing the triangular field panels 10 correspondingly, and the remainder is the vertical gable panel 13, and then each trapezoidal field panel 11 is sequentially extended, wife panel 1
3, the size of the flat side inclined part 7 is determined according to this, and the size of the flat side inclined part 7 is determined as necessary. Field panel 9... has been selected. Therefore, when the gable side slope part 8 is set only with the triangular field panel 10, the flat side slope part 7 only needs to use one triangular field panel 10 of the same size as the flat side slope part 7, and the gable side slope part 8 is If a trapezoidal field panel 11 is added to this, the trapezoidal field panel 1
1 is used in the flat side inclined portion 7.

The field panels 9 constituting the flat-side inclined portion 7 are arranged from above into a triangular field panel 10, a trapezoidal field panel 11, and so on, which are arranged vertically in a continuous manner.

On the other hand, the field panels 9 of the gable side slope part 8+1 and the flat side slope part 7 are arranged symmetrically, and their width is 2" If necessary, it is possible to use the expanded version of 455 shown in Fig. 3(b), but it is better to adjust this by interposing the square field panel 12 described above in order to improve the load-bearing property. convenient.

In the flat side slope part 7, each field panel 9 has slope beams 4,
The vertical side of the frame 14 is sequentially placed on the frame 4 and fixed thereto with nails or the like. At this time,
Since each field panel 9 does not have structural plywood 19 on one or both of the upper and lower intermediate members 17 and 18, the frame 1
4 are directly installed in a stacked manner above and below, and then a separate long structural plywood 20 is stretched and fixed between these frames 14, 14. Note that, of course, when the gable side panel 13 is used, a separate rectangular panel 22 is used below the flat side inclined part 7, and the child side roof part 7 in the vertical direction is constituted as a whole. .

On the other hand, in the W-side inclined section 8, a starter 21 with a triangular cross section is installed on the gable panel 13 (or on the ceiling joist 6 when the entire gable-side inclined section is made), and the surface of the gable-side inclined beam 5 is installed. A field panel 9 is installed as a reference in the same way as the flat side slope part 7.

Since the frame 14 of each field panel 9 has the oblique side structural material 16 installed at an angle, the field panel 9 along the flat side sloped part 7 and the field panel 9 along the gable side sloped part 8 have the sloped side structural material 16 installed on the frame 14 of each field panel 9. The comrades will come into contact with each other in a sloping mountain shape at their intersecting positions, and by fixing these parts with nails or the like, they can be made into a hipped roof with a continuous and integral surface.

By the way, in the present invention, if twice the apex angle of the flat side sloping part is set as the angle of the apex angle of the gable side slanting part, the reference angle can be determined as appropriate.

In addition, it is possible to not only fix the sloped mountain shape in the flat side slope part and the gable side slope part, but also to do it indirectly by interposing a member with a triangular cross section between them. This can also be done after being fixed in advance.

Furthermore, the dimensions etc. of each field panel are not limited to these, but can be determined by considering the load capacity etc. as appropriate. It is also possible to use additional panels.

Although the present invention has been constructed as described above, it is natural that the specific configurations may be changed in carrying out the invention as long as the gist of the invention is not violated.

(Effects of the Invention) Since the present invention is constructed according to the gist of the invention, the average slope and the gable side slope constitute a continuous and integrated surface by the triangular field panel and the trapezoidal field panel, and these are arranged in three directions. Since it is supported by an inclined beam, sufficient load bearing capacity can be ensured as a whole.

For this reason, when creating a hipped roof, there is no need to install corner timbers for load support or reinforcing trusses to support the corner timbers, and therefore there is no need for a structure on the back side of the hipped roof to partition it. This allows the space to be secured effectively.

In addition, the field panels were triangular field panels and trapezoidal field panels whose widths were expanded in stages, so by using the necessary ones from these, the sloped part of the gable side of the hipped roof was It is possible to select and install the entire roof as appropriate, and to change the shape of the roof.
