Description

The present invention relates to a tight frame for a fitted folded plate roof.

BACKGROUND ART Conventionally, a folded plate structure roof called a fitting type has been implemented.

To briefly explain this mating type folded plate structure roof, it consists of a tight frame with a mating head on the top, a mountain part supported on the top surface of this mating head, and both left and right ends of the mating head. This method uses a fitting-type folded plate roofing material that has an engaging recess that allows the locking part of the frame to be locked. Simply fit the folded plate roofing material from above the tight frame and apply a downward load. Then, the engaging recesses of the folded roofing material are caught and locked by the locking parts provided on both the left and right ends of the fitting head, and the lower surface of the peak is supported by the upper surface of the fitting head, and the fitting head is closed. By overlapping and tightening the edge portions of the ends of adjacent folded plate roofing materials, the adjacent folded plate roofing materials are joined together, and the locking portions are prevented from engaging and disengaging from the engagement recesses. (For example, see the reference diagram showing the usage state and the reference enlarged sectional view showing the usage state of Patent Document 1.)

This kind of interlocking type folded plate structure roof is not only easy to construct, but also has folded plates directly attached to at least two places on the left and right sides of the fitting head of the tight frame, instead of being fixed at one place like the hanger fixed type. Because it has a structure in which the roofing material is locked and fixed, the roof has high fixation strength and exhibits excellent durability against upwelling forces caused by strong winds. This interlocking folded plate structure roof is attracting increasing attention.

In addition, to further explain the tight frame used for this interlocking type folded plate structure roof, a band-shaped metal plate is bent into a shape with continuous peaks and valleys (wave shape) to form the frame base. , a fitting head that can support the lower surface of the peak of the folded plate roofing material on the upper surface and has locking parts on both left and right ends that can be locked in the engagement recess of the folded plate roofing material, is connected to the peak of the frame base body. It is attached to the top of the holder by means of fastening means such as caulking.
