Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a single-slope roof for a structure such as a sunroom, which is provided along a pair of walls constituting an exit corner or an entrance corner of a building.

(Prior Art) Conventionally, in the case of a single-slope roof for a sunroom that has roof portions arranged along a pair of walls that intersect with each other, the inclination angle and projecting width of both roofs, that is, the width of each roof portion relative to the corresponding wall, have been determined. The angle of inclination and the horizontal distance between the eaves girders of each roof section and the corresponding walls are set to be equal.

However, if there are restrictions on the installation space of the sunroom, the slope angles and widths of both roofs must be set to be different.

(Purpose of the invention) The purpose of the invention is to create a roof that can be installed so that the roof parts that are placed along a pair of walls constituting an exit corner or an entrance corner of a building have mutually different inclination angles and extension widths. Our goal is to provide the following.

(Structure of the invention) The present invention is a single-sided roof that is supported by a pair of walls constituting an exit corner or an entrance corner of a building and a plurality of supports arranged at intervals from the walls. includes a roof section disposed along each wall, at least one of the roof sections swinging in a ridge support fixed to the wall corresponding to the roof section to enable the angle of inclination of the roof section to be changed. A rafter body comprising a movably supported ridge member and an eave spar member swingably supported by an eave spar receiver supported by the pillar, and in which both roof portions are located on the intersection line of these. and a common rafter comprising a splint frame connected to the rafter body so as to be swingable about its axis and connected to the ridge members and eave beam members of each roof portion.

In this invention, "the inclination angle of the roof part" means:
An angle between a roof portion and a virtual plane perpendicular to the wall surface of the wall corresponding to the roof portion.

(Operations and Effects of the Invention) According to the invention, the inclination angle and projecting width of each roof part are changed by swinging the roof part with respect to the ridge support or the eaves sill support, and the intersection of both roof parts is changed. It is determined by the position of the line, i.e. the position of the common rafter of both roof sections.

For example, when setting a common rafter to be at the same angular position from each wall on a virtual horizontal plane, that is, when the intersection angle between the common rafter and the ridge material or eave girder material of both roof sections is equal, one It is possible to obtain a roof in which the inclination angle and the width dimension of one roof part are the same as those of the other roof part.
In addition, the common rafters are arranged so that the angle formed between the common rafter and the ridge material or eave spar material of one roof section is larger than the angle formed between the common rafter and the ridge material or eave spar material of the other roof section. When setting the position, one roof portion can have a slope angle smaller than that of the other roof portion and a protrusion width dimension larger than that of the other roof portion. The splint, which is swingable with respect to the rafter body of the common rafter, lies in the same plane as the respective roof section in both of the above cases.

(Embodiments) The features of the present invention will become clearer from the following description of the illustrated embodiments.

Referring to FIG. 1, the projecting corner 10a of the building 10

A single-slope roof according to the present invention is shown supported on a plurality of supports 16 spaced from each wall.

The roof shown is a sunroom 1, which is a type of building.
8 and includes a roof section 20 disposed along one wall 12 and a roof section 22 disposed along the other wall 14. This roof is formed so that the inclination angle α and protrusion width l ₁ of one roof portion 20 are the same as the inclination angle β and protrusion width l ₂ of the other roof portion 22 (α=β, l ₁ =l ₂ ). (See Figures 1 and 2).

Each roof part has a ridge material 24 extending along the corresponding wall, and an eave girder material 2 extending parallel to the ridge material at a distance and located at a lower height than the ridge material 24.
6, a plurality of rafters 28 connected to the ridge members 24 and the eaves beam members 26 and spaced apart from each other, and a common rafter 30 for both roof sections. A glass plate 34 is provided in the space surrounded by the ridge material, eave spar material and rafters, the space between the pillars, the pillars, the space 32 connecting the pillars and the space surrounded by the eave spar material 26.
are inserted into each.

The ridge material 24 is between the rafters 28 and between the rafters 28 and 30.
The wall 1 consists of a plurality of cross members extending in a line, fixed to said rafters between them, as shown in FIG.
ridge support 3 fixed to 2 via a plurality of screws 36
8 is swingably supported. The ridge member 24 has a locking portion 24a at its lower end, which has an arc-shaped cross section and can be locked to a locking portion 38a, which will be described later, of the ridge support.
The ridge support 38 has a locking portion 38a at its lower end, which has an arcuate cross section and whose outer surface is slidably in contact with the inner surface of the locking portion 24a. Thereby, the roof portion 20 can be angularly rotated around the locking portion 38a to change its inclination angle. Ridge support 3
8 has at its upper end an eaves portion 38b consisting of a horizontal plate-like portion that covers the upper part of the ridge material 24. A plate-shaped body 40 connected to the rafter 28 is connected to the eave part 38b so as to be angularly rotatable about an axis parallel to the axis of the locking part 38a, thereby connecting the roof part 20 and the ridge support 30. This prevents rainwater from entering the house through the gaps.

In addition, the eave girder material 26 is provided between the rafters 28 and between the rafters 2.
A glass plate support member 4 consisting of a plurality of cross members extending in a line and fixed to the rafters between 8 and 30.
It consists of a cylindrical body attached to the lower surface of 2 with screws. The cylindrical body has a half-moon-shaped cross section and extends parallel to the wall 12, with the arcuate surface of the half-moon directed downward. Posts 16 that support the eave girder material 26

4 and is fixed to the pillar 16 via a screw 46 while maintaining the roof portion 20 at a predetermined inclination angle. A screw 47 is attached to the glass plate support member 42.
A rain gutter 48 is attached via the. however,
The rain gutter, the eaves section 38b, and the plate-shaped body 40 are omitted in FIG.

On the other hand, the roof section 22, like the roof section 20, has ridge supports (not shown) and struts fixed to the wall 14 so that the roof section can change its angle of inclination with respect to the corresponding wall 14. It is swingably supported with respect to an eave spar support (not shown) attached to the eaves sill 16. Instead of making the inclination angle variable, the roof portion 22 may be installed so as to incline only at a preset inclination angle. Conversely, the slope of the roof portion 22 may be variable and the slope of the roof portion 20 may be constant.

As shown in FIG. 4, the common rafter 30 is connected to a rafter body 50 located on the intersection line of both roof portions 20 and 22, and is rotatably connected to the rafter body about its axis, and A pair of extending splints 5
It consists of 2,54.

The rafter body 50 has a pair of arcuate surfaces 5 when viewed in cross section.
It consists of a substantially cylindrical member having 0a and 50b.
The arc lengths of the upper and lower arc surfaces 50a and 50b are set to be longer or shorter than the illustrated arc length, as necessary.

The splint frames 52, 54 each include two members 56,
58. One member 56 of each splint frame has a water stop portion 56a that is slidably in contact with the upper arcuate surface 50a of the rafter main body via the sealing material 60 when viewed in cross section, and has approximately the same curvature as the lower arcuate surface 50b. It also has a concave surface portion 56b that is slidably in contact with the arcuate surface. The other member 58 has a recessed groove 58a which forms part of the roof portion and is capable of receiving the edge of the glass plate 34 adjacent to the protruding corner 10a, as is clear from FIG.
The upper and lower side portions of the member 58 are connected to the ridge material 24 and the eave beam material 26 that support the glass plate.

One member 56 in each splint and the rafter body 50 are connected by screws 62, and both members 56, 5
8 and the rafter body 50 are respectively connected by screws 64, and each splint frame is maintained at a predetermined rotation angle with respect to the rafter body 50. Prior to this connection and setting of the rotation angle, each splint frame is attached to the rafter body 50 so that each roof portion 20, 22 having a preset inclination angle and each splint frame 52, 54 are on the same plane. 52 and 54 are maintained at a predetermined rotation angle. In this example, since the inclination angles α and β of both roof portions 20 and 22 are set to be equal, the splint frames 52 and 54 are maintained at the same rotation angle.

A roof having roof portions with mutually different inclination angles and projecting widths can be formed as follows.

For example, as shown in FIG.
The lengths of the ridge members and eave beam members of one roof portion 20 are set to approximately the same dimensions as in the previous example, and the intersection angle θ ₁ formed by the ridge material and eave beam material of one roof portion 20 and the common rafter 30 is When setting the arrangement position of the rafters 30, that is, the position of the intersection line of both roof parts 20 and 22, so that the angle θ ₂ formed by the girder material and the common rafter 30 is larger, the inclination angle α of one roof part 20 is The roof can be made such that the inclination angle β of the other roof portion 22 is smaller (α<β) and the projecting width l ₁ of the roof portion 20 is larger than the projecting width l ₂ of the roof portion 22 (l ₁ >l ₂ ). In this case, the angle formed by the common rafter 30 with the virtual horizontal plane is the same as in the previous example. The common rafter 30 is positioned such that the imaginary elevation containing its axis lies between the imaginary extension elevations of each wall 12,14.

This roof is assembled on both roof parts 2 at the construction site.
Walls 12, 14 and pillars 16 corresponding to 0, 22
This can be done by attaching a common rafter 30 to each roof section. that time,
Since each roof portion is swingable with respect to the eave support 38, it can be installed so as to have a preset inclination angle. In addition, the rafters 30 common to each roof portion 20, 22 are connected to each splint 5.
2 and 54 are swung around the axis of the rafter main body 50, the member 58 can be butted against and connected to the end face of the ridge member 24, the side edge of the glass plate 34, and the end face of the eave girder member 26.

In addition, instead of the above-mentioned assembly method, a part of each roof part obtained by dividing each roof part and a common rafter 30
are assembled in advance as a unit in a factory, and at the construction site, the unit and the other divided parts of each roof section connected to the unit are attached to the walls 12, 14 and the support column 16, and the unit and the divided parts are mutually attached. can be connected to. When the unit is attached to walls 12, 14 and posts 16, the portion of each roof section 20, 22 is angularly rotated via each splint 52, 54 with respect to the axis of rafter body 50 and each ridge member 24. This allows the unit to be attached to each roof section 5.
2, 54 can be installed so that the part has a predetermined inclination angle.

In the example described above, the roof is arranged along both walls 12, 14 that are perpendicular to each other, but as shown in FIG.
8 and 68, 70.

The roof in this example extends continuously along walls 66, 68, 70, with roof portion 72 corresponding to wall 66.
, a roof portion 74 corresponding to the wall 68 , and a roof portion 76 corresponding to the wall 70 .

In this example, the inclination angle of the roof portion 72 is the largest, and the inclination angle of the roof portion 74 is set larger than the inclination angle of the roof portion 76. Further, the projecting width of the roof portion 72 is the smallest and the roof portion 76 is
The width of the roof portion 74 is set to be the largest, and the width of the roof portion 74 gradually increases from the side of the roof portion 72 toward the side of the roof portion 76.

Although not shown, the present invention can be applied to a pair of walls that intersect with each other at an acute angle and form a protruding corner.

Furthermore, the single-slope roof according to the present invention can be arranged along a pair of walls forming an internal corner (not shown) instead of an external corner as shown in the figure, and furthermore, the external corner and the internal corner can be arranged alternately. It can also be applied when it appears. The intersection angle of the walls may be a right angle, an obtuse angle, or an acute angle.
