Description

[Detailed explanation of the invention] This invention relates to a layered roofing tool, and its purpose is to make it possible to easily and firmly layer roofing over an old roof without removing the existing roof. Furthermore, the present invention provides a layered roofing structure that can sufficiently withstand strong winds by increasing the degree of adhesion between the old roof and the new roof, and has an extremely good appearance without worrying about leakage from the surface work.

Next, the structure and operation of this invention will be explained with reference to the drawings.

As shown in the perspective view of FIG. 1 and the cross-sectional view of FIG. It has a lower wall 3a narrower than the width, and left and right side walls 3b are bent and formed on both sides of the lower wall 3a, and a through hanger 3 is provided by bending and forming a collar part 3c on the outer upper end of the left and right side walls 3b, The lower wall 3a of this hanger 3
is fixed to the center of the upper wall 2a of the hanger support material 2 by welding or fastening, etc., to form a roofing tool main body a having steps 4 at right angles to both ends of the upper wall of the hanger support material 2, and a threaded hanger is formed. A cap 5 having the same shape and size as 3 and having a restraining wall 5b suspended from the end of the flange 5a is provided, and the cap 5 is fitted onto the upper part of the roofing tool body a. .

Then, as shown in the construction state in FIG. 3, the hanger supports 2 of the roofing tool body a are externally fitted onto the tile rods 6a of the old roof 6, and the left and right flanges 1 of the hanger support members 2 are attached to the nails 7. It is fixed to the rafter 8 with a fastening member such as.

1. In advance, both sleeves of the new roof shingle 9 are bent upward at an obtuse angle to the horizontal bottom wall to form a side wall portion 9a, and the upper end of this side wall portion 9a is passed through the step portion 4 and the hanger 3. It is formed into a U-shape 9b that fits into the side wall 3b and the flange 3c.

Next, a new roof board 9 is overlaid on the top surface of the old roof 6, and the upper end U-shaped part 9b of both ends 9a of the roof board 9 is fitted into the step part 4, side wall 3b, and flange part 3c of the roofing tool body a. Then, the cap 5 is passed through and fitted onto the receiving material 3.

By fitting the cap 5, the restraining wall 5b of the cap 5 restrains the U-shaped portion 9b.

In addition, in order to fit the U-shaped part 9b of the new roof sheet 9, it may be fitted from the side or from above, but if it is fitted from above, the new roof sheet 9 should be overlapped. The flange portion 3c may be formed in a bent manner.

Since this device is constructed as described above, the hanger support material 2 of the roofing tool body a is externally fitted and fixed onto the tile rods 6a of the old roof 6, and both ends of the new roof board 9 overlapped. A new roofing can be constructed by a simple operation of fitting the U-shaped part 9b into the stepped part 4 and fitting the cap 5 thereon, thereby significantly improving work efficiency.

Also, as shown in the enlarged view of FIG. 3, the U-shaped part 9b of the new roof board 9 is securely fitted and restrained by the step part 4, side wall 3b, flange part 3C, and restraining wall 5b, and is in a hugging state, so it is not exposed to strong winds. It is capable of withstanding external forces such as

Furthermore, during the construction work, the nail 7 only needs to be fastened once, and this fastened part is immediately covered with the new roof sheet 9 and further covered with the cap 5, so there is no need to worry about rain leaks. It turns out.

Furthermore, the appearance is good because only the new roof plate 9 and cap 5 that are connected are clearly visible.

However, with this design, the bolt heads do not protrude outward like in conventional layered roofing, so the design is highly effective and the risk of rain leaks is completely eliminated.

In addition, the conventional layered roofing was extremely vulnerable to strong winds and was extremely dangerous, but with this new roof board 9, the U-shaped part 9b, t < step part 4 and the restraining wall 5b fit into each other to completely prevent extraction. This makes the layered roof extremely strong against strong winds.

Furthermore, it has great practical effects, such as being able to overlap the conventional tile rods 6a with almost no change in their appearance.

Japanese Utility Model Application Publication No. 53-99820 has been proposed as this type of device, but since this does not have a hanger support material, the through hanger must be fixed with nails together with the tile rod. Even if it is fixed to a corroded tile rod, the connecting force is small, and it cannot withstand long-term use because it only touches the hanger through the brim at the end of the side wall of the new roof board.

In addition, simply abutting the collar as shown in the example above causes dimensional errors, making standardization difficult.

However, in the present invention, a hanger support material with a gate-shaped cross section is fixed to a through-hanger, and by fitting this hanger support material onto a tile rod, the hanger support material becomes like a new tile rod. The strength is increased, and there is no need to attach the hanger to the tile rod with nails.

In addition, a part with a stepped part is formed between the hanger support material and the hanging hanger, and the part of the new roof sheet is fitted into this part, and the cap is fitted and fixed, so it is strong. It is tightly bound, can withstand long-term use, and can be standardized.

In addition, the gap between both roof panels can eliminate the inconvenience caused by the difference in expansion between the two roof panels.
