Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof repair structure in which a new roof is raised on an existing roof that has been raised using a corrugated roof plate such as a small wave slate.

[0002]

2. Description of the Related Art As a conventional roof repair structure, as shown in FIG. 3, for example, a corrugated roof board b such as a small wave slate is laid on a purlin a made of a C-shaped steel as a supporting member and raised. New corrugated roof boards c, c are laid on the existing roof, and both end rising portions d, d of these new corrugated roof boards c, c.
The first and second overlapping surface portions e and f extending outwardly from the upper and lower surfaces are overlapped with each other, and the outer edge portions of the overlapping surface portions e and f of the new corrugated roof plate c are bent downward. The first and second hanging pieces g and h are formed, and the overlapping surface portions e and f of the existing corrugated roof board b and the new corrugated roof boards c and c are formed.
There is a construction in which a tight frame i is interposed between the above and the tight frame i, and the tight frame i is fixed on the purlin a through the existing corrugated roof board b by a fixing tool such as a screw j.

[0003]

However, in such a conventional roof refurbishment structure, the new corrugated roof plates c, c are used.
The overlapping parts e and f of the two, the second hanging piece h of the new corrugated roof plate c on the lower side, and the head of the tight frame i are fixed to each other by fasteners such as screws k and l. Therefore, the positioning of the new corrugated roof plates c, c can be performed only by the width of the head portion of the tight frame i.

In addition, since the legs of the tight frame i supported on the valleys of the existing corrugated roof board b also serve as the fixing parts, the rain-proofing function of the existing roof can be improved in case of accidental infiltration of water. I can't accept it.

Further, when the fixing portion which is the leg portion of the tight frame i is fixed on the purlin a with a fixing tool such as a screw j,
The tight frame i is not arranged because the new corrugated roof plate c is provided so as not to contact the existing corrugated roof plate b in order to avoid the protrusion by the head of the screw j. At the site, the displacement of the newly installed corrugated roof c changes drastically due to the load condition acting on the new roof, and when a large load is applied, it is deformed by the protrusions and the like.

In addition, in a roof structure having a corrugated roof board b having a small wave shape such as a small wave slate, the pitch of the peaks and valleys of the corrugated roof board b is generally uneven. In addition, since a large number of corrugated roof boards b are often stacked at the time of transportation, the pitch of the crests and troughs of the corrugated roof boards b tends to widen and there is variation. During the repair work on the existing roof, the overlapping surface portions e and f of the new corrugated roof plates c and c adjacent to each other due to the positioning of the tight frame g are not properly assembled, which causes deterioration of aesthetics and rain. There was a problem that the performance was poor.

[0007]

An object of the present invention is to properly assemble a new corrugated roof board on an existing corrugated roof by a tight frame,
It is intended to provide a roof refurbishment structure capable of improving aesthetics and rain finish.

[0008]
