DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for a roof panel joint of a building such as a house.

[0002]

BACKGROUND ART As a roof of a building such as a house, there is a roof composed of a plurality of roof panels arranged in parallel and a roof finishing material. At this time, the roof panel is formed of a base frame made of a combination of steel materials and the like, a base plate attached to the base frame, and a planar member (roofing or the like) attached to the base plate.

[0003] The roof panels are juxtaposed with a gap at a joint between the roof panels and other roof panels in order to absorb errors in erection and construction dimensions. Then, the roof finishing material is fixed on these roof panels arranged side by side to complete the roof.

The joint between the roof panels is provided in Japanese Utility Model Publication No. 6-10024 and Japanese Patent Laid-Open No. 1-29.
As shown in Japanese Patent No. 9948, a waterproof tape is stuck on each roof panel, and a roof finishing material is fixed thereon to perform a waterproof treatment. As this waterproof tape, a modified waterproof bitumen tape having a high waterproof property has been mainly used.

[0005]

However, when the roof finishing material is heated by solar radiation or the like, the temperature under the roof finishing material also becomes high. For this reason, there has been a problem that the waterproof tape attached to the joint of each roof panel is softened by heat and drips from a gap between the roof panels.

When the waterproof tape softens and drips,
The tape may become thin and eventually disappear, resulting in reduced waterproof performance. Further, when the waterproof tape is fixed with a nail or the like, the nailing portion easily expands in the nail hole due to heat, so that the waterproof tape cannot be fixed and may fall from the joint.

[0007] For this reason, there is a problem that the repair work of the waterproof tape, for example, the work of peeling off the roof finishing material and replacing the new waterproof tape, etc., must be performed periodically, and the maintenance is difficult. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a waterproof structure for a roof panel joint which can prevent dripping or dropping of a waterproof tape, prevent a decrease in waterproof performance at a roof panel joint, and can be easily maintained. Is to do.

[0009]

The present invention will be described with reference to the drawings. The present invention relates to a waterproof structure for a joint 10 between two roof panels 1 arranged adjacent to each other. Cover the heat-resistant cover material 5 and
The waterproof member 6 is stuck on the top.

Since the gap between the joints 10 is closed by hanging the cover member 5 over the roof panel 1, even if the temperature under the roof finishing material 15 becomes high due to solar radiation or the like, the waterproof member 6 is softened. In addition, the waterproof member 6 does not drip or drop into the gap between the roof panels 1. If the waterproofing member 6 does not drop, the softened waterproofing member 6 returns to its original state due to a decrease in temperature, so that a reduction in waterproofing performance can be prevented.

This eliminates the need to periodically perform the repair work of the waterproof member 6, for example, the work of peeling off the roof finishing material 15 and replacing the new waterproof member 6, thereby facilitating the maintenance and management of the roof.

The cover member 5 can be made of, for example, a heat-resistant asphalt tape having a high melting temperature, and is particularly formed of a glass fiber reinforced material such as a glass fiber tape which is inexpensive and has good heat resistance. Is preferred.

Further, the cover member 5 is provided on the roof panel 1.
It is preferable that an adhesive is adhered to at least one surface so that it can be fixed securely. Further, an adhesive may be attached to both surfaces of the cover member 5 so that the cover member 5 can also be adhered and fixed to the waterproof member 6.

As the cover member 5, for example, a metal material having heat resistance may be used. However, the cover member 5 is made of the above-described glass so that it can be easily attached to a ridge or a valley of a roof. It is preferable that the flexible member be made of a flexible member that can be easily bent such as a fiber reinforced material.

Further, the cover member 5 is extended to a joint 10 between two other roof panels 1 adjacent to the two roof panels 1 over which the cover member 5 is bridged, and at least the corners are gathered. It may be extended over four roof panels 1 adjacent to each other.

As a result, a portion where the corners of the four roof panels 1 are gathered, that is, a portion where the joining line between the roof panels 1 intersects can be covered with the continuous cover material 5.
The gap at the intersection can be reliably closed.

Further, the roof panel 1 comprises a field board 3 and
The cover member 5 has a planar member 4 such as a roofing that is pasted on the base plate 3 while leaving a predetermined width dimension from an edge of the base plate 3, and the cover member 5 includes the planar member 4 of two adjacent roof panels 1. Is preferably stuck over the end portion not stuck.

As a result, since the cover member 5 is not overlaid on the sheet member 4, the step between the cover member 5 and the sheet member 4 is reduced or eliminated, and the waterproof member 6 is moved from the cover member 5 to the sheet member 4. Up to 4 can be easily pasted.

An adhesive is attached to both sides of each cover member 5 provided at the joints 10A and 10B, and is adhered to the base plate 3, the waterproof tape 6, and the waterproof sheet 7. .

As shown in FIG. 5, in a portion where the joining portions 10A and 10B intersect (a portion where the corners of the four roof panels 1 are gathered), the joining portion 10A in a direction perpendicular to the eave tip edge is formed. The covering member 5 to be closed is extended to a joint 10A between the other two roof panels 1 adjacent to the two roof panels 1 and is laid over the four roof panels 1. The waterproof tape 6 also covers the cover material 5 and the roofing 4,
It overlaps on the waterproof sheet 7 and is similarly affixed.

In this embodiment, the roof 1
3 is formed by the following procedure. First, in a factory, the roof panel 1 is assembled by the base frame 2, the base plate 3 and the roofing 4. Then, the assembled roof panel 1 is transported to the site.

At the site, the transported roof panel 1 is installed on the upper part of the building body 12, and the joint 1 between the roof panels 1 is formed.
