Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel which is joined to each other to form a roof of a building, and more particularly to a roof panel with a roofing which is pre-installed at a factory or the like for waterproofing the roof top surface. Regarding the construction method of the roof used.

[0002]

2. Description of the Related Art In recent years, the construction of houses has been industrialized. For example, the components such as walls, floors, and roofs have been made into panels at the factory in advance, and these panels have been assembled at the construction site to build houses. Part of the panel construction method is to use. As a panel used in such a panel construction method, for example, as a roof panel,
The vertical core member and the horizontal core member are assembled into a rectangular shape, and the reinforcing core member is vertically and horizontally assembled inside the rectangular frame to form a frame body, and a face material such as plywood is attached to one surface of the frame body. The one worn is generally.

In order to construct a roof using the above roof panel, a plurality of roof panels are sequentially laid on a frame, the roof panels are joined together to form a roof surface, and then the roofing is performed on the roof surface. I am trying to apply. When roofing is applied to the roof surface, it is traditionally done by horizontal attachment. That is, as shown in FIG.
The roofing piece 30 in the form of a strip is laid along the roof ridge direction, and the lower edge of the roofing piece 30 on the upper side in the inclination direction of the roof is superposed on the upper edge of the roofing piece on the lower side in the inclination direction from above. I am trying.

[0004]

However, in the method of constructing a roof as described above, the installation of the effervescent drainer is done on-site, which is one of the factors impairing industrialization. Therefore, it is possible to preliminarily lay roofing on each roof panel in a factory etc. In this case, if roofing is laid horizontally on each roof panel as in the conventional case, the roofing piece itself will be smaller than in the past. In addition, the number of roofing pieces is increased, which not only requires labor for laying the roofing pieces, but also increases the number of joints between the roofing pieces, which is not preferable for waterproofing.

The present invention has been made in view of the above circumstances. Even when the roofing (piece) is laid on the roof panel in advance, the roofing (piece) itself can be made relatively large and the number of the roofing (piece) can be reduced, and the roofing (piece) can be reduced. (1) An object of the present invention is to provide a roof panel with a roofing having relatively few joints between them and a roof construction method using the roof panel.

[0006]

In order to achieve the above object, the roof panel with roofing according to claim 1 of the present invention comprises a roofing which is laid in advance on the upper surface of the roof panel.
It is formed in the shape of a strip extending in the direction of inclination of the roof.

A roof panel with a roofing structure according to a second aspect of the present invention is the roof panel with a roofing structure according to the first aspect, wherein among the roof panels joined in the inclination direction of the roof, the roofing laid on the roof panel located on the upper side in the inclination direction has a lower roof direction. The side end projects from the end of the roof panel.

A roof panel with roofing according to claim 3 is the roof panel according to claim 1 or 2, wherein:
It is composed of a plurality of strip-shaped roofing pieces extending in the direction of inclination of the roof, and a waterproof tape is attached to the joint between these roofing pieces.

According to a fourth aspect of the present invention, in the method of constructing a roof, when the roof panel with roofing according to any one of the first to third aspects is laid on the upper part of the frame, the joints between the roof panels adjacent to each other in the inclination direction of the roof are joined. In the above, the lower end of the roofing of the roof panel located on the upper side in the inclination direction is overlapped with the upper end of the roofing of the roof panel located on the lower side in the inclination direction from above.

According to a fifth aspect of the present invention, in the roof construction method according to the fourth aspect, at the joints of the roof panels adjacent to each other in the ridge direction of the roof, the roofing roofing edges of the roof panels are abutted to each other, and the abutted portions are joined together. The feature is that a waterproof tape is attached to.

[0011]

In the roof panel with roofing according to the first aspect, since the roofing which is laid in advance on the upper surface of the roof panel is formed in the shape of a strip extending in the direction of inclination of the roof, the roofing itself is different from the case where the roofing is pasted horizontally. Can be increased to reduce the number of
The number of seams is also reduced.

In the roof panel with roofing according to a second aspect of the present invention, among roof panels joined in the inclination direction of the roof, the lower end portion of the roofing which is laid on the roof panel located on the upper side in the inclination direction is inclined. By superimposing the roof panel on the lower side of the roof in the upper end of the roofing from above, the raining of the joint between the roofing and the roofing adjacent to each other in the inclination direction of the roof becomes good.

According to another aspect of the roof panel with roofing of the present invention, a waterproof tape is attached to a joint between a plurality of strip-shaped roofing pieces extending in the direction of inclination of the roof so that the roofing pieces are adjacent to each other in the roof ridge direction. The rain finish of the seams between them is improved.

In the roof construction method according to the fourth aspect of the present invention, at the joint between the roof panels adjacent to each other in the inclination direction of the roof, the lower end of the roofing roof panel located on the upper side in the inclination direction is set to the lower side in the inclination direction. By superimposing the roof panel on the upper part of the roofing from above, the roof will have a good rain finish at the joint between the roofing and the roofing.

In the roof construction method of claim 5, at the joints between the roof panels adjacent to each other in the ridge direction of the roof, the roofing roofing edges of the roof panels are butted against each other, and the waterproof tape is provided at the butted portions. By attaching the sticker, the rain finish of the joint between the roofing adjacent to the roof ridge direction will be improved.
