Description

Detailed Description of the Invention 【Technical field】

The present invention relates to the structure of an M-shaped roof of a steel frame prefabricated house.

[Background technology]

In the conventional M-type roof, that is, the snow-free construction method, since members such as beamers, sheaves, and purlins were assembled one by one at a high place on the site, it took time and labor for construction, There has been a problem that the risk of work accidents increases as the time spent on site work increases.

[Object of the Invention]

The present invention has been made in view of the technical background as described above, and its object is to simplify the construction by using a prefabricated assembly member (gradient member) for the bed beam, the bundle, and the purlin. In addition, the purpose is to shorten the construction time, reduce the work at height, improve the safety, and increase the support strength by this member.

DISCLOSURE OF THE INVENTION

In the structure of the roof according to the present invention, a plurality of bundles 3 are vertically erected between the bed girder 1 which is horizontally arranged and the purlin 2 which is arranged above the bed girder 1 and is inclined. The reinforcing face material 4 is stretched over the opening a at the end where the height of the bundle 3 is high among the openings a surrounded by the bed beam 1, the purlin 2 and the pair of bundles 3 and the height of the bundle is increased. It is characterized in that the reinforcing surface material 4 is opened without being stretched in the opening a at the end on the lower side, and the roof material 9 is laid on the purlin 2 of the gradient material 5 via the rafters 8 The bed girder 1, the bundle 3 and the purlin 2 are integrally formed into a collective member and further reinforced by the reinforcing surface member 4 in the vertical direction, the horizontal direction and the diagonal direction. Support strength can be obtained. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The gradient member 5 is shown in FIG. 1, and a purlin 2 is arranged so as to incline above the floor girder 1 which is horizontally arranged. A plurality of slants are provided between the floor girder 1 and the purlin 2. A stack 3 of is upright. Therefore, the gradient member 5 has a trapezoidal shape having an inclination in the purlin 2. Further, the opening a surrounded by the pair of bundles 3, the bed girder 1 and the purlin 2 is closed by the trapezoidal plate-shaped reinforcing surface member 4,
The periphery of the reinforcing face material 4 is fixed to the bed girder 1, the bundle 3 and the purlin 2. As shown in FIG. 1, the reinforcing surface member 4 is a bundle 3 of the openings a.
Although it is attached to the opening a at the end on the higher side, the reinforcing surface material 4 may be attached to more openings a. However, as shown in FIG. 1, the reinforcing surface member 4 is not attached to the opening a at the end of the opening a on the side where the height of the bundle 3 is low so as not to be blocked. It should be noted that the purlin 2, the bundle 3, the bed girder 1 and the reinforcing surface member 4
Is made of wood, and the gradient material 5 is manufactured in a factory. In this way, the constructed gradient member 5 is fixed on the beam 7 or the column so as to abut on the lower side with the gutters 6 as shown in FIG. The rafters 8 are laid over the main building 2 of the sloped material 5, and the roof boards 8 and the folded plate roofing material 9 are laid on the rafters 8 to form an M-shaped roof.

【The invention's effect】

Since the present invention is configured as described above, the assembled gradient member can be easily installed by simply hoisting it on a high point of a house frame with a crane or the like and fixing it on a beam or a pillar. This has the advantage that the construction time can be shortened and the safety of work in high places is increased. Moreover, since the bed beam, the bundle, and the purlin are reinforced by the reinforcing surface material,
There is an advantage that the load bearing strength of the gradient material in the horizontal direction, the vertical direction and the diagonal direction can be increased. Further, of the openings surrounded by the bed beam, the purlin, and the pair of bundles, a reinforcing face material is stretched over the opening at the end of the higher bundle height and the opening at the end of the lower bundle height is reinforced. Since the face material is opened without being stretched, it can be efficiently reinforced by reinforcing the bundle with high height and the need for reinforcement with the reinforcement face material, and the height of the bundle is low. The openings that do not require much reinforcement can be used as openings for passing wiring and piping without being blocked, and the wiring and piping in the attic can be easily designed.

[Brief description of drawings]

FIG. 1 is a front view showing a gradient member according to an embodiment of the present invention, and FIG.
The figure is an explanatory view of the construction state of the same as above, and FIG. 3 is a partially cutaway perspective view of a house having an M-shaped roof as above. Material, 5 is gradient material, 8
Is a rafter, 9 is a roofing material, and a is an opening.

Claims (1)

[Claims] 1. A slope member is formed by vertically arranging a plurality of bundles between a horizontally arranged bed girder and a purlin that is tilted above the bed girder to form a slope member. Among the openings surrounded by the pair of bundles, the reinforcing surface material is stretched over the opening on the side where the height of the bundle is high, and the reinforcing surface material is stretched over the opening on the side where the height of the bundle is low. The roof structure is characterized in that it is made open and the roofing material is laid on the main roof of the gradient material via the rafters.
