Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof surface joining structure and joining method, and in particular, it can be used for a roof of a prefabricated building in which a plurality of factory-prepared roof surfaces are connected in an inclined direction.

[0002]

2. Description of the Related Art Conventionally, various prefabricated construction methods have been adopted in building construction such as houses in order to simplify on-site work. For example, the prefabricated building 60 shown in FIG. 6 adopts a unit-type prefabricated construction method in which a plurality of building units such as a roof unit 61 and a living room unit 62 produced in advance in a factory are arranged and stacked at a construction site to construct a building. Has been done.

In this prefabricated building 60, each roof unit
The roof surface 63 attached to the 61 is formed in a gabled roof shape by arranging a plurality of roof surfaces 63 in the inclined direction or the orthogonal direction to the inclined direction. These roof surfaces 63 are roof panels that are formed by preliminarily attaching a roofing to the entire front surface of the base plate and laying a predetermined roofing material on the roofing.

In such a prefabricated building 60, rainwater and the like flow down from the ridge-side roof surface 63A toward the girder-side roof surface 63B in an inclined direction, so that at the construction site, the ridge-side roof surface 63A and the girder side. There is a demand for reliable waterproofing between the joint edges of the roof surface 63B.

[0005] Specifically, a waterproof sheet is laid so as to straddle the ends of the roof side 63A and the girder side roof surface 63B facing each other, and then the ridge side roof surface 63A and the girder side roof. It is general that the roof member for joining is erected and fixed across the surface 63B (that is, so as to cover the waterproof sheet).

By the way, there is a roof surface used in the prefabricated construction method in which a large number of roof materials are laid in a substantially straw-like shape in the direction of inclination. When such roof surfaces are continuously provided in the inclined direction, not only waterproof treatment is performed between the joint edge portions of the ridge-side roof surface 63A and the girder-side roof surface 63B, but also the joint portions are not conspicuous. Something like that is needed.

Therefore, the applicant of the present application inserts one end of the joining roof material into the back side of the girder side roofing material of the ridge side roof surface, and inserts this joining roofing material from the front side of the girder side roofing material toward the ridge side roof. We proposed a waterproofing method for roof panel joints that are nailed and fixed to the ground plate of the surface (Japanese Patent Application No. 4-37994). The joining roof material in this method is driven into a location where a waterproof member such as butyl rubber is interposed between the front side of the ridge side end of the joining roof material and the back side of the girder side roof material of the ridge side roof surface. It is fixed to the ground plate with a nail.

[0008]

By the way, in this method, it is necessary to nail the work for fixing the roof member for joining to the place where the waterproof member is arranged. Since these are performed after the roof surfaces are connected to each other, that is, on-site work, there is a problem that the work on the construction site becomes complicated.

In particular, since the waterproof member is arranged on the back side of the girder side roof material on the roof side of the ridge, it is difficult to confirm the location where it is hidden by the roof material. Further, the joining roof material and the girder side roof material are likely to be damaged by cracking due to the impact of nailing by a hammer or the like. In such a case, repair work or replacement work of the damaged joining roof material or girder side roof material is required. For these reasons, there is a problem that the site work becomes more complicated.

[0010] Further, since the roofing of each roof surface 63 is connected through a waterproof sheet extending over the respective end portions, rainwater and the like that have flooded the roof material back side of the ridge-side roof material 63A There is a risk that water will flow down on the roofing in an inclined direction, and water will infiltrate the back side of the waterproof sheet. Therefore, there is a risk that rainwater or the like may enter the inside of the roof unit 61, and there is also a problem that reliable waterproofness cannot be obtained.

[0011] These problems are caused by the panel type prefabricated structure in which a roof portion is formed by attaching a substantially flat roof panel, which is a roof surface produced in advance in a factory or the like, to a frame such as a steel frame at a construction site. The construction method has also occurred, and a solution has been desired.

An object of the present invention is to provide a joining structure for a roof surface and a joining method that can simplify field work and obtain reliable waterproofness.

[0013]

Further, the locking member is preferably made of a weather-resistant material which can be easily bent by a worker at a construction site and can be maintained in a bent state and which does not cause rust or the like due to aging. Stainless steel plates can be used.

Further, in the roof surface joint structure of the present invention, the roof surface on the ridge side and the roof surface on the girder side are provided with roofing on the entire front surface of the base plate, and the roofing on the roof surface on the ridge side is a girder side end. It is preferable that the portion extends toward the girder-side roof surface and is laminated and connected on the ridge-side end portion of the roofing of the girder-side roof surface.

Here, the roofing on the roof side of the ridge may be laminated and connected to the roofing on the roof side of the girder by an appropriate means such as adhesion or welding, and a waterproof sheet may be further laminated on the connecting portion. Then, the extended portion of the roofing on the girder side roof surface may be pushed into the back side of the girder side roofing material together with a holding member such as urethane, etc. until use.

In the method for joining roof surfaces of the present invention, a large number of roof materials are laid on a base plate in a substantially straw-like shape, and end edges of a ridge-side roof surface and a girder-side roof surface, which are continuously arranged in an inclined direction, are joined to each other. In addition, it is a method for joining roof surfaces in which a joining roof material is erected and fixed between the respective joining edge portions, and an insertion gap is formed in advance on the roof material back side of the girder side end portion of the ridge side roof surface. In addition, a locking member capable of bending and locking the girder side end of the joining roof material is provided on the front side of the girder side roof surface on the ridge side end side, and the ridge side roof at the construction site. After the surface and the girder side roof surface are continuously provided in the inclined direction, the ridge side end of the joining roof material is inserted into the insertion gap, and the locking member is bent to form the girder side of the joining roof material. It is characterized by locking the ends.

Further, in the roof surface joining method of the present invention, the roof surface of the ridge side and the roof surface of the girder side are preliminarily pasted with roofing on the entire front surface of the base plate, and the roofing surface of the ridge side is roofed. The girder-side end portion of the girder-side roof surface is extended toward the girder-side roof surface, and the girder-side end portion of the roof side of the ridge-side roof surface is roofed before the joint roofing material is erected and fixed. It is preferable to stack and connect the ends on the ridge side.

[0020]

According to the present invention as described above, the roof member for joining is installed and fixed by inserting the ridge side end into the insertion gap and then bending and locking the girder side end by the locking member. To do. Therefore, since the nailing work is not necessary when the roof material for joining is erected and fixed, it is not necessary to search for a nailing location as in the prior art, and the risk of damaging the roof material is eliminated and the on-site work can be simplified. become.

[0021] Then, in each roof surface, if the girder side end of the roof side roof surface is laminated and connected on the roof side end of the roof side roof surface of the girder side roof surface, the roof surface of the roof side of the roof side is connected. It is possible to improve waterproofness because there is no risk of rainwater or the like flowing down from the connecting portion, and these can achieve the above-mentioned object.
