Description

[Detailed description of the invention] The present invention relates to an improvement of a round butt end wrap that is attached to the end of a rafter, etc. More specifically, the present invention relates to an improvement of a round end wrap that is attached to the end of a rafter, etc. A large number of strips 2 are bent inwardly at right angles to the outer frame 1, and the tips of the strips 2 are folded back to form folded pieces 3.
This pertains to a round-shaped kiguchi winding in which the folded pieces 3 of 2 are fitted into the folded pieces 3 of adjacent strips 2, and the adjacent strips 2 are overlapped.

In the conventional round butt end winding, in order to have a structure that can be adjusted according to the diameter of the end, a number of strips 2' are extended from the front part of the outer frame 1' as shown in Fig. 1. It was bent inward at right angles so that adjacent strips 2' were overlapped.

However, such a conventional round end wrapper has the problem that the strips 2' tend to turn over as shown in FIG. 2, allowing rainwater to penetrate into the end of the wrapper and spoiling the appearance.

The present invention has been made in view of the above points, and its purpose is to provide a round-shaped wood-cut winding in which the strips for adjusting the diameter of the wood-cut are not turned over. .

Hereinafter, the present invention will be explained in detail based on examples.

A large number of strips 2 are formed on one side of the strip plate B by a plurality of notches 7 through a rear folded piece 6, and a front folded piece 12 is provided on the other side of the strip plate B. .

This band-shaped plate B is wound into a cylindrical shape to form an outer frame,
A connecting portion 8 provided at one end of the outer frame 1 and a connected portion 9 provided at the other end are slidably overlapped, and the rear folding piece 6 on the front end side of the band plate B is folded back to project forward. A flange 10 is formed, and each strip 2 is bent inwardly at a right angle to the outer frame 1, and adjacent strips 2 are overlapped with each other.

The tip of the strip 2 is folded back to form a U-shaped folded piece 3, and the folded piece 3 of the strip 2 is fitted into the folded piece 3 of the adjacent strip 2. In this state, two adjacent strips are overlapped.

Reference numeral 4 denotes a disc-shaped head plate disposed within the outer frame 1, and a locking piece 5 extends forward from the outer peripheral edge of the head plate 4, and this locking piece 5 is attached to the folded piece 3. It is locked.

The round wood wrapper A, which can be shaped in this way, can be made of copper plate, steel plate, resin-coated metal plate made by coating a thin metal plate with synthetic resin, metal plate with an uneven pattern, etc.

Therefore, during construction, the overlapping margin between the connecting part 8 and the connected part 9 of the outer frame 1 of the round end winding A is changed in accordance with the end 13 of the rafter, etc., and the amount of overlap between the adjacent strips 2 is adjusted. change the
The outer frame 1 of the round butt end winding A is fitted onto the end 13 and fixed by driving nails 11 from the outer periphery.

14 is a folding line.

As described above, the present invention involves folding the tip of a strip backwards to form a folded piece, and then fitting the folded piece of the strip into the folded piece of the adjacent strip to overlap the adjacent strips. Therefore, adjacent strips are connected by folded pieces, and even if a strip tries to turn over, it is restricted by the adjacent strip, preventing rainwater from penetrating into the wood end due to the strip turning over. This has the effect of maintaining the aesthetic appearance.

[Brief explanation of drawings]

Figures 1a and b are a sectional view and an enlarged partial front view of the conventional example, Figure 2 is a diagram showing the state in which the above strip is turned over, Figure 3 is a perspective view of the embodiment of the present invention, and Figure 4. is a cross-sectional view of the same as above, FIG. 5 is an enlarged partial front view of the same strip of strip before forming a folded piece, FIG.
The figure is a cross-sectional view of the round wood end wrapper attached to the wood end, where 1 is an outer frame, 2 is a strip, and 3 is a folded piece.

Claims (1)

[Scope of utility model registration request] A number of strips extending from the front of a cylindrical outer frame with both ends overlapped and connected to each other are bent inward at right angles to the outer frame, and the tips of the strips are folded backwards. A round-shaped Kiguchimaki made by folding back the strips to create a shape, and then inserting the folded strips of one strip into the folded strips of the adjacent strip, overlapping the adjacent strips.
