Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a roof structure, and more particularly to a technique for constructing a wide free space below a ridge with a ridge in between while sufficiently supporting the roof load.

[Background Art] Conventionally, in a roof structure, as shown in FIG. 5, a ridge truss 1a is constructed over the entire length of the ridge to support roof loads. For those installed directly below the ridge, there is a problem that the attic space below the ridge is divided by the ridge truss 1a, and it is not possible to obtain a large space that unites the space below the ridge. Ta. However, if the ridge truss 1a is reduced, the roof load cannot be supported sufficiently.

[Object of the invention] The present invention has been made in view of these problems,
The purpose is to provide a roof structure that can sufficiently support the roof load while also forming a wide space below the roof extending on both sides of the lower part of the ridge.

DISCLOSURE OF THE INVENTION 1 The roof structure of the present invention comprises ridge trusses 1, which are arranged substantially parallel to the ridge length direction at a certain small interval from the ridge core on both sides of the ridge core.
1, and a ridge beam 3 is constructed between the tops of the opposing substantially triangular gable panels 2 and 2, which are constructed at the gable end of the gable roof, and a roof panel P is stretched between the ridge beam 3 and the ridge truss 1, and the ridge truss is 1 and a roof panel P is stretched between the supporting members 4 on the eave side, and the ridge truss 1 is configured to support the roof load near the ridge. By doing so, the above objective was achieved. In other words, the ridge trusses 1 and 1 are erected approximately parallel to the ridge length direction with a fixed small interval from the ridge center on both sides of the ridge core, and the ridge truss 3 is erected between the tops of the end panels 2 and 2. , a roof panel P is stretched between the ridge beam 3 and the ridge truss 1, and a roof panel Pa is stretched between the ridge truss 1 and the supporting material 4 on the eave side from this, so that it is installed near the ridge core in the ridge length direction. The pair of ridge trusses 1, 1 can support the roof load near the ridge, and in this way, the pair of ridge trusses 1,
By supporting the roof load with 1, the ridge shirasu that was always used in the past can be omitted, and the ridge core can be removed while the roof load can be sufficiently supported with the ridge 1 and 1. There is no ridge truss below the ridge to divide it, allowing a wide open space to be created below the ridge.

Embodiments of the present invention will be described in detail below based on the drawings.

As shown in FIGS. 1 and 2, the roof of the building 5 extends between the upper ends of the outer wall 6 on the gable side, and is spaced apart from the ridge core at a certain small interval on both sides of the ridge core, approximately in the ridge length direction. The ridge trusses 1 and 1 are constructed in parallel.

This ridge truss 1 is supported by columns 7 of the outer wall 6 and columns 8 inside the building 5. Furthermore, on the gable side, substantially triangular gable panels 2, 2 are supported on the pillars 7 and the outer wall G. A ridge beam 3 is then constructed between the tops of the end panels 2, 2. A plurality of lower chord members 9 are installed between the upper end of the outer wall 6, which is substantially parallel to the ridge length direction, and the lower end of the ridge truss 1. 10 is erected, and diagonal members 11 are installed at the opening from the upper end of the ridge truss 1. A roof panel P long in the ridge length direction is stretched between the ridge beam 3 and the ridge truss 1, and a roof panel P long in the eave direction is stretched between the ridge truss 1 and the outer wall 6 serving as a support material 4 on the eave side. It is stretched.

In this way, the ridge trusses 1, 1 are erected substantially parallel to the ridge length direction with a certain small interval from the ridge core on both sides of the ridge core, and the ridge beam 3 is installed between the tops of the end panels 2, 2. Erection, leader 3
By stretching the roof panel P between the ridge truss 1 and the ridge truss 1, and by stretching the roof panel Pi between the ridge truss 1 and the supporting material 4 on the eave side, a pair of ridges installed near the ridge core in the ridge length direction can be created. The roof load near the ridge is supported by the ridge truss 1, 1, and while the roof load is sufficiently supported by the ridge truss 1, 1, a conventional ridge truss is placed below the ridge core in the vertical direction. This creates a large empty space below the ridge.

By the way, to briefly explain the concept of the structure of the present invention, when the length from the ridge to the outer wall 6 of the conventional building 5 is one span, the conventional left and right building blocks A.

In the present invention, the building block A is constructed by combining B blocks as shown in FIG.
, add another building block C between B and see Figure 3 (
The combination shown in b) resulted in a length of 3 spans in the longitudinal direction of the gable. Furthermore, if the roof is configured as in the present invention,
If one of the pair of ridge trusses 1゜1 is made long, and the roof is constructed around the long ridge truss 1, a small roof 12 will be formed on the gable side end as shown in Figure 4. It is possible to carry out construction such as installing.

In the present invention, a central truss 13 may be installed at the center of the ridge truss 1, 1 in the length direction to increase the strength.

[Effects of the Invention] In summary, the present invention has a structure in which a ridge truss is erected approximately parallel to the ridge length direction at a certain small interval from the ridge core on both sides of the ridge core, and the ridge truss is installed between the tops of the end panels. The roof panel is stretched between the ridge beam and the ridge truss, and the roof panel is stretched between the ridge truss and the supporting material on the eave side. The roof load near the ridge can be supported, and by supporting the roof load with a pair of ridge trusses in this way, the ridge truss, which was always used in the past, can be omitted, and the roof load can be supported by the ridge truss. While providing sufficient support, there is a ridge truss below the ridge core that divides it (therefore, it has the advantage of being able to create a wide open space below the ridge).
