Abstract

PURPOSE:To build a garret having a wide space in a state that no strut is located below the garret by a method wherein triangular roof support trusses are disposed in a position where a garret below a ridge is used as a room, and the two ends of the truss are supported by the struts. CONSTITUTION:A stay 52 is erected and protruded in a position on a horizontal material 51, and the upper end of the stay 52 are coupled to the end parts of the horizontal material 51 by means of oblique materials 53 and 54 to form a roof support truss 5. The end parts of the horizontal material 51 of the truss 5 are supported by struts 3. A principle rafter 4 is arranged in a state to be connected to the oblique material 54 at the same inclination angle of the oblique material 54, and is supported by the struts 3.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention uses the attic as a living room. It is installed between a roof frame structure and can be used as a storage room.

[Conventional technology]

In order to make effective use of narrow sites, houses have been put into practical use in which the attic is used as a storage room or a room such as a living room.

Conventionally, when using the attic, the method shown in Fig. 2 has generally been adopted. This is done by arranging bundles T at predetermined intervals on the roof beam H (lattice beam) of the second floor on the top of the through column P, and establishing the bundle T. A gassho O is placed between the T's, and a support stick S is placed in the adjacent east room as necessary, and a place with sufficient height to use the attic as a living room, for example, a 3. It is used as a living room or a storage room on the first floor.

[Problem to be solved by the invention]

Since the gassho O near the ridge is supported by a long bundle TI along with the ridge M, if this part is used as a living room, the bundle will be exposed inside the living room. This does not pose much of a problem when used as a storage room, but when used as a living room, the pillars protrude from the center of the room, making it difficult to create a large space and creating a sloping ceiling.

The object of the present invention is to provide a roof frame that eliminates the bundles in this part when the attic is used as a room.

[Means to solve the problem]

The present invention has been made to achieve the above-mentioned object. A triangular roof support truss is arranged in the attic below the ridge where it is used as a room, and both ends of the truss are supported by bundles.
The gist is to construct a large space attic with no bundles below the attic ridge.

[For production]

By omitting the bundles in the ridge of the attic and installing roof support members in the shape of a chevron-shaped triangle, both ends of which are supported by the bundles, a large space without bundles is secured in the attic. Yes, use this as a room. Since there are no bundles (pillars) inside the room, it can be used as a general room.

〔Example〕

The present invention will be explained below based on the illustrated embodiments.

Figure 1 is an explanatory diagram showing the roof frame of the present invention, where l is the through-pillar 2.
A lattice beam (or roof beam) supported on the lattice beam 1, and a bundle 3 for supporting the gassho 4 according to the roof slope on the lattice beam 1.
are arranged and established at predetermined intervals.

The part where the attic is used as a living room, a storage room, etc. For example, the bundle and ridge at the bottom of the ridge where the attic is the highest are omitted, and this ridge part is shaped into a chevron-shaped triangle as shown in Figure 2 (A). The roof support truss 5 is used. This roof support truss 5 is shown in FIG. 2(A). As shown in (B), a horizontal member 51 having a length arranged on the opposing bundles 3 and 3 of the ridge portion, a shed bundle 52 that is protruded at a predetermined position of this horizontal member 5l, and this shed. Two diagonal members 53, 5 are arranged so as to connect the upper end of the bundle 52 and the horizontal member end bolts.
4, and the ridge 6 is supported by the shed bundle 52, which is configured in a chevron-shaped triangular shape (truss shape). In this case, as shown in FIG. 2(A), one diagonal member 54 is arranged so as to have the same inclination angle as the gassho 4 supported by the bundle 3, so that the diagonal material 54 and the gassho 4 are It is arranged so that consecutive pitches are placed at the same inclination angle. Note that the other diagonal members 53 may have the same slope and length as shown in Figure (A), but they can also have different lengths and slope angles as shown in Figure CB>. It is determined appropriately according to the shape of the roof of the building.

Further, in the above embodiment, the four members were assembled into a frame shape to form a triangular mountain-shaped roof support truss, but it is also possible to form a panel by pasting a panel on one or both sides of the roof support truss.

〔Effect of the invention〕

In the shed silk structure of the present invention, a triangular roof support truss is arranged at the position where the attic below the ridge is used as a room, and both ends of this truss are supported by bundles, so that there is a large space without bundles under the attic ridge. Since the attic is constructed of a roof, the attic can be effectively used as a living room without pillars, and the ceiling can be made horizontal.
