Description

Description: TECHNICAL FIELD The present invention relates to a door truss constructed on one side of a substantially central portion of a left and right span at a gable side end of a gable roof, and more specifically, a door panel. The present invention relates to a technique for making it possible to withstand the load of the small roof projected to the gable part and to facilitate the construction of the exposed part other than the small roof.

[Prior Art] Conventionally, as shown in FIG. 8, a small roof 8 is overhanged at the end on the gable side of the gable roof at a position that is one step lower than the large roof 6 at one side of the center of the left and right span. In order to form the gable subspace 7 with the small roof 8, the small roof 8 is assembled into a roof, and the exterior plate 5 is stretched on the gable side wall portion adjacent to the small roof 8.

[Problems to be Solved by the Invention] However, since the construction of the roof and the exterior plate 5 are separately performed in this manner, the number of construction steps is increased, and the roof panel of the small roof 6 is also supported at the end portion on the gable side. Was required separately, and there was a problem that the configuration became complicated.

The present invention has been made in view of such problems,
It is an object of the present invention to provide a door truss for the gable side end portion of a gable roof, which simplifies the structure of the gable side end portion and improves workability.

[Means for Solving the Problem] The door truss at the gable side end portion of the gable roof of the present invention is arranged at one end of the gable side end portion of the gable roof at a substantially central portion of the gable roof and the left and right spans. With the roof panel support point P at the approximately central portion as the apex, the slope door truss A is configured in a truss structure with the diagonal member 1, the longitudinal member 2 and the lower chord member 3, and the diagonal member 1 of the facing door truss A and A connecting metal fitting 10 is attached at an intersection with the vertical member 2, and an inclined plate-like receiving metal fitting 12 is attached to the diagonal member 1 on the opposite side of the connecting metal fitting 10. The roof panel 6a of the large roof 6 on the side is mounted and the roof panel 8a of the small roof 8 is mounted and supported on the connection fitting 10, and the bottom part b of the door truss A is used as a base. An exterior plate 5 is stretched over the exposed portion 4 excluding the equilateral triangle d portion. Is.

[Operation] As described above, the roof panel support point P, which is arranged at one end of the gable roof at the end of the gable roof substantially in the center of the left and right spans and has the roof panel support point P at the center of the left and right spans as the apex, By making the surface door truss A into a truss structure with the vertical member 2 and the lower chord member 3, the surface door truss A at the end of the gable side has a truss structure, and the surface door truss A is projected to the gable portion. The structure does not require a structural material for supporting the load of the small roof other than the face door truss A, and the structure is simplified, and the bottom portion b of the face door truss A is the bottom side. By installing the exterior plate 5 on the exposed portion 4 excluding the substantially isosceles triangle d portion, the exterior door 5 of the exposed portion 4 can be constructed by constructing the surface door truss A, and the workability is improved. Then
Further, the finish is improved without the positional deviation of the exterior plate 5.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

A pair of right-angled triangular trusses 9, 9 are arranged back to back at the gable side end of the gable roof, and the pair of trusses 9 serve as the door truss A of the present invention. On the side door truss A side, a small roof 8 is formed at a position lower than the large roof 6 and a gable subspace 7 is formed on the gable side.

The door truss A is arranged on one side of the substantially central portion of the left and right spans as described above. The roof panel support point P at the approximate center of the left and right spans is used as the apex, and the diagonal member 1, the vertical member 2 and the lower chord member 3 form a truss structure. Since the door-door truss A has a truss structure as described above, the door-door truss A withstands the load of the small roof 8 projecting on the gable portion of the door-door truss A and supports the load of the small roof other than the door-door truss A. It does not require a structural material for the purpose. Specifically, as shown in FIG. 6, a mountain-shaped connecting fitting 10 is attached to the intersection of the diagonal member 1 and the longitudinal member 2 of the door truss A with bolts 11, and the connecting fitting 10 of the diagonal member 1 is An inclined plate-shaped receiving fitting 12 is attached to the opposite side. However, the roof panel 6a of the large roof 6 on the main body B side is mounted on and supported by the lever 12 and bears the load, and the roof panel 8a of the small roof 8 is mounted and supported on the connecting bracket 10. It bears the load and supports the roof load. As described above, the roof door truss A supports the roof load, and a separate supporting structure member is omitted, and the structure is simplified.

Further, the exterior plate 5 is stretched on the exposed portion 4 excluding the substantially isosceles triangle d portion having the base portion b of the face door truss A as the base, and by applying the face door truss A, the exterior of the exposed portion 4 is covered. The plate 5 can also be constructed, the construction property is improved, the outer plate 5 is not displaced, and the finishability is also improved.

As shown in FIGS. 4 and 5, at the end portion of the door truss A, a connecting fitting 13 is interposed between the wall panels 14 to connect the wall panel 14 and the door truss A together with the wall panel. 1
It is also used to connect the four braces and to connect the braces 15.

[Effects of the Invention] In summary, the present invention is arranged on one side of the central portion of the left and right spans at the gable side end portion of the gable roof and has a roof panel support point at the approximate center portion of the left and right spans as the apex. Since the door door truss is made into a truss structure with wood, vertical material and lower chord material,
The door-door truss at the end of the gable side has a truss structure, and a connecting metal fitting is attached to the intersection of the diagonal member and the vertical member of the door-door truss, and is attached to the diagonal member on the opposite side of the connecting metal Since the roof panel of the large roof on the main house side is mounted on the inclined plate-like receiving metal fittings, it bears the load, and further, the roof panel of the small roof is mounted and supported on the connecting metal fittings. Therefore, by supporting the roof load, it is possible to bear the load of the small roof projecting on the gable part by the door truss, and to support the load of the small roof other than the door truss. There is an advantage that the structure can be simplified without requiring a structural material. And since the exterior plate is stretched on the exposed part except the approximately isosceles triangle part having the bottom part of the face door truss as the base, by installing the face door truss, the exterior plate of the exposed part can also be constructed, There is an advantage that the workability can be improved, the positional deviation of the exterior plate can be eliminated, and the finishability can be improved.
