Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a work to create a curved roof that is lightweight and has high structural strength by simple technical means in order to expand the internal space of the attic of a steeply pitched roof and utilize that space as a living space. This relates to construction methods.

Various methods of constructing curved roofs have been developed in order to increase the internal space of the attic. Many have been used to make roof frames by bending and processing, but these have the disadvantage of being heavy and requiring special techniques.

The present invention relates to a wooden roof assembly that is lightweight and can be easily constructed by unskilled workers.

To explain the present invention with reference to drawings, FIG. 1 shows a plurality of curved plates 3 with spacing members 4 fixed between an upper vertical member 2 located at the top T of the roof frame and a lower horizontal member 1 located near the eaves N. is curved into a bow and bulges outward, and fixed by nailing with spacing members 4 and splints 5 to form a curved composite beam K in the shape of a climbing beam having the required beam cross section. are attached to form a roof frame, the upper part of the curved composite beams is passed over, and on top of that, flexible sheathing boards 13 are placed in the direction of the slope of the roof.
An arbitrary roofing 14 is constructed by fixing the roof with nails.

The left and right sides of the curved composite beam are assembled separately and connected at the top of the roof in a clasped shape, creating an ``A'' shape on the left and right sides.

The curved composite beam K will be explained with reference to FIGS. 2 and 3. The curved board 3, which is the main member for forming the curved surface, is a flexible, hard-elastic band-like board made of wood that can be driven with nails, and is made of plywood with a thickness of about 9 mm or board material with a thickness of about 12 mm. To form and assemble a curved composite beam, first draw an actual size drawing of the curved plate 3 on the floor of the workshop with the position and dimensions of the lower horizontal member 1, 1, vertical member 2, spacing member 4, and splinter 5 horizontally. Write from e, place each member at the position t, and assemble. As shown in Fig. 3, on the original size drawing, the temporary ruler 25 is temporarily fixed, the lower horizontal member and the upper vertical member are fitted and fixed in that position, and the lower curved plate 3 with the spacer fixed is placed between them. The intermediate curved plate 3 is formed into a predetermined curved surface by adding the hypothetical standard 25F,
Next, the required number of seven curved plates 3 are arranged in order with the upper curved plate 3 and maintained at a predetermined interval S. Next, as shown in Fig. 2, place the lower horizontal member (3) (3) and the spacing material 4.1, the vertical member 2 and the spacing material 4, and the lower spacing material 4 at the intermediate position with the splint plate 5, respectively. It is fixed by nailing to form a curved composite beam K in the shape of a climbing beam. The cross-sectional views of each part of the curved composite beam are as shown in Figures 4 to 7. The beam configuration can be freely set (this can be set, and the number of curved plates (30) can be increased or decreased depending on the required strength, so each part can be You can adjust the strength of the parts.

To install the curved composite beam, as shown in Fig. 8, insert the groove 17 of the lower horizontal member into the rectangular member 18 installed two FIs above the second floor.
The second floor beam is connected and fixed to the curved composite beam using a ball (19), which is fitted with reinforcing plates 23 from both sides to prevent the eaves from moving from side to side. As shown in Figure 9, the upper part of the curved composite beam is bolted or nailed together with other upper vertical members symmetrically with splints 5, and the shed bundle 8 and shed beam 7 are attached to form a shed assembly. After passing the taruki 12 over the curved composite beam and nailing the flexible sheathing board 3 in the direction of the roof slope, a relatively light metal plate (such as a known metal plate) was attached to the sheathing board. 4) The roof is made of durable material.

The upper and lower ends of the curved plate 3 are a lower horizontal member 1 and an upper vertical member 2.
The curved board 3 is fixed by nailing to the spacer 4 that was installed.
If the inner angle where the end of the lower horizontal member 1 and the upper vertical member 2 meet is an extremely acute angle, as shown in FIG.
If fixed, the curved plate 3 and the curved plate side surface of the adjustment member 220 will be
The edges are at right angles, making it easier to attach the spacer 4 at the end of the curved plate and to nail the curved plate 3.

As shown in Fig. 11, a shed bundle 8 is attached to the upper part of the curved composite beam.
The end of the second-story beam 11 is attached to the lower part of the shed beam 7 in advance at the factory, and the roof beam is connected to the opposing shed bundle 8 and second-story beam 11 with a bold bolt to form the shed frame. It can also be formed. Although we have assumed that the roof frame is installed on the second floor, it can be installed anywhere on the first or third floor, or on a beam.

The joining and fixing of the present invention is mainly done by nailing, but if an adhesive is also used on the joining surfaces, the joining strength can be further increased.

As described above, the present invention does not require any special technology, and moreover, the curved composite beam K bulged in an arc shape is connected to II via the taruki 12.
Since the flexible sheath board 14 is fixed to one piece, the sheath board 14 also becomes a structural member of the roof, and it exhibits high strength against external forces such as snow loads and wind pressure that are applied to the roof, and the roof as a whole is lightweight. Because of this, it is possible to reduce the cross section of structural members such as foundations and columns, so it has many advantages, such as being able to provide buildings with living space in the attic at low cost.
