Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof portion of a building in which a plurality of roof panels are combined to form a roof portion, each roof panel is prepared in advance in a factory, and the plurality of roof panels are mutually assembled on-site. The present invention relates to a seal structure in a ridge connecting portion of the roof panel in a step of forming a roof portion by combining them.

[0002]

2. Description of the Related Art Conventionally, in a building having a panel structure, roof panels such as a roof panel structure are combined and joined to form a roof portion of the building, and the roof portion made of the roof panel has an appropriate shape, The roof and the ridge were formed by raising a roofing material of an appropriate material and applying a wrapping and the like in the ridge.

In such a conventional construction method, the roofing material is raised at the construction site, and further, in order to carry out the work such as sealing and connecting at the site by using the building wrapping and its fixing tool.
It required a long construction time and had many drawbacks such as the problem of working conditions such as weather and the problem of working efficiency.

Therefore, it is considered that a plurality of roof panels constituting the roof portion are unitized in advance in a factory to shorten the construction period at the construction site and to simplify the work. In this case, each roof panel has a waterproof sheet attached to the surface of the roof panel structure, and various roofing materials are sequentially raised from the lower end of the roof panel structure, and the ridge-side end of the roofing material is attached to the roofing material. It is considered that the roof panel is configured with the ridge packing fixture attached to the.

[0005] Then, a joint portion where the plurality of roof panels are abutted against each other, a joint portion between the building cover fixtures at the joint portion between the building cover fixtures and the building cover of the roof panel, and a joint purlin Since it is necessary to seal the ridges that are butt-joined to each other via the roof, a special seal structure suitable for construction of roof panels has been desired.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to effectively and easily seal a joint portion in a ridge portion of each roof panel when the roof portion is constructed by joining the plurality of roof panels. To provide a seal structure for achieving the above, the seal structure targeted by the present invention is naturally applied to a corner ridge in the case of a dormitory roof, for example.

[0007]

According to the present invention, a combined purlin provided at the upper end of each roof panel structure of roof panels adjacent to each other in a ridge, and a roof panel previously assembled on the roof panel structure. A waterproof adhesive tape is attached to the entire joint portion of the ridge so that it simultaneously covers the upper surface of the seal portion of the ridge packing fixture that covers the ridge-side end of the roofing material.

[0008]

EXAMPLE FIG. 1A shows the roof panel 01 of the present invention.
1 shows an outline of a building 10 in which the building 10 is used, and the building 10 has a roof portion 11 formed by joining roof panels having several shapes. Further, as shown in FIG. 2B, among the roof panels 01 constituting the roof portion 11, rectangular roof panels located on both sides of the central portion are joined above the roof portion 11 to form the ridge 13, the roof corner portion. In the same manner, each of the triangular roof panels constitutes the corner ridge 13.

FIG. 2 shows a basic structure of a roof panel 01 arranged in the central portion of the roof, which is an example of the present invention. Each roof panel 01 essentially has a roof panel structure 12, a roofing material 15 which covers the upper surface of the roof panel structure, and a water repellent portion between an edge of the roofing material ridge side and an upper surface of the roof panel structure. It is composed of a ridge packing fixture 17 in which A is interposed and fixed.

At the joint portion of the roof panel 01 in the ridge portion, a joint purlin 14 is fixed to the ridge-side end portion of the roof panel structure 12. In this case, the combined purlin 14 also has the same length as the width of the roof panel structure 12 and is integrated in advance at the factory to form a part of the roof panel 01.

As is apparent from FIG. 2, a waterproof sheet 16 is usually applied to the upper surface of the roof panel structure 12 before the roofing material is raised. As a result, most of the invading rainwater flows down on the upper surface of the waterproof sheet 16 and reaches the lower end of the roof, so that rainwater is unlikely to penetrate into the roof panel structure 12.

In this way, the roof panel 01 preassembled in the factory has the roof panel structure 12, the joint purlin 14, the roofing member 15, and the waterproof sheet 16 shown in FIG.
And it is made to have a ridge-pack fixing tool 17, and by constructing this at the construction site, for example, in the state of FIG. 1,
It significantly simplifies the roof construction process.

FIG. 3 shows the details of the ridge portion 20 which is formed by uniting the unitized roof panel 01 as shown in FIG. Ridge 2
The structure of both roof panels 01 in No. 0 is clear also in FIG. 2, but the surface of the roof panel structure 12 of the roof panel 01 which has been unitized in the factory in advance is already covered with the waterproof sheet 16. Since the ridge-side end of the roofing material 15 is covered by the water return portion A of the ridge packing fixture 17, most of rainwater blown up from between the ridge packing 22 and the surface of the roofing material 15 is ridged. Water repelling part A of the packet fixing device 17
Is guided along the surface of the waterproof sheet 16 and flows down to the lower end of the roof.

On the other hand, the space between the building cover fixtures 17 on the left and right roof panels 01 in the drawing is sealed by the waterproof adhesive tape 21 which is a characteristic feature of the present invention. FIG. 4 shows a process of applying the waterproof adhesive tape 21 which is the seal member of the present invention.

In the ridge portion of the roof panel 01 joined from the left and right of the ridge portion 20 via the joint ridge 14, the ridge-pack fixing tool provided at the ridge-side end of the roofing material 15 of the left and right roof panels 01. A waterproof adhesive tape 21 is adhered between 17 and 17.
In this case, the width of the waterproof adhesive tape 21 sufficiently covers the upper surface of the water return portion A of the ridge packing fixture 17, the adhesive surface of which is the left and right water return portions A, the ends of the sheet 16 on the roof panel structure 12, and It is attached so as to cover the entire combined purlin 14.
As an example, a waterproof adhesive tape 21 having a width of 180 m / m is used.

After that, as shown in FIG. 3, the ridge packing 22 is coupled and fixed by the ridge packing fixing portions of the ridge packing fixtures 17 provided in advance on the left and right roof panels 01. Therefore, although the ridge 20 is almost completely waterproofed by the ridge, even if rainwater is blown from the gap between the upper surface of the roofing material 15 and the end of the ridge 22 beyond the ridge-fixing part. Since the joint portion of the roof panel 01 is completely sealed by the waterproof adhesive tape 21, rainwater does not penetrate into the structure of the roof panel. Although omitted in the above description, it is needless to say that the same seal structure as described above is also applied to the corner ridge portion of the dormitory type roof.

[0017]

[Effect] According to the invention of the present application, in a state where the roof panel including the roofing material, the waterproof sheet, the ridge packing fixture, the joint ridge, etc., which has been assembled in advance on the roof panel structure in the factory, is assembled at the construction site. , It is possible to extremely easily perform a sealing work only by sticking a ready-made waterproof adhesive tape to the ridge of the roof panel, and at the same time, a wing envelope is provided on the upper part of the seal structure.
By attaching it to the ridge packing fixture, which is also attached to the roof panel, the two work together, and the sealing work in all the ridges of the panel structure building can be performed extremely simply and reliably.
