Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a re-roofed horizontal roof constructed by covering existing thin roof tiles such as slate tiles.

[Conventional technology]

Conventionally, in order to replace a roof that was already covered with thin roof tiles (asbestos-based lightweight tiles), it was done by removing all the roof tiles and replacing the roof, but this was a time-consuming process. Moreover, it is difficult to reroof the building while it is still in use.

Also, leave the existing thin roof tiles as they are.
Metal rafters are passed over these, metal roofing sheets are covered with plywood, etc., and if necessary, insulation material is interposed between the metal rafters and the roofing sheets, but this The overall thickness of the roof, including the thickness of the roof tiles, becomes thicker, and when applied to the first floor roof of a two-story building, rain tends to leak from between it and the second-story building rising from it, and the roof becomes thicker. As the weight increases, there is a risk that problems may arise with the strength of the pillars that support it.

Therefore, as shown in Fig. 1, metal roof plates 2 are placed on the existing thin roof tiles 1, and these are fixed to wooden rafters 4 with nails or wood screws (not shown) that pass through the roof tiles 1. It is known to be thatched.

However, this horizontal roof has the same width in the eave direction.
Since a plurality of roof plates 2 of the same shape are connected to cover the existing roof tiles 1, depending on the size of the roof, the eave tip of the roof plate 2 located closest to the eaves and the roof tile 1 In addition, the position of the roof tile 1 and the roof shingle 2 covering the roof tile 1 is unsightly due to misalignment with the tip of the eaves.
There was a drawback that a large air layer 5 was formed between the two and the rain noise became louder.

In addition to the above, there are other methods, such as cutting out part of the eave tile and eave member during construction to form a flat part covered with plywood, and then sequentially covering the roof with plywood over that flat part. Cut the tip and
Another method is to attach arabesque to the roof and then sequentially lay out the roofing boards from there. However, these conventional methods not only require a lot of time and effort during construction, but also have the problem that after finishing, an unnatural appearance remains between the tip of the eaves of the roof and the roof surface.

[The problem that the idea attempts to solve]

This invention was devised in order to eliminate the various drawbacks of the conventional ones mentioned above, and it does not require removing the existing roof tiles or increasing the thickness or weight of the roof as a whole, and it also reduces the sound of rain. To provide a re-roofed horizontal roof that is easy to work with and has a good appearance without causing any discomfort between the tip of the eaves and the roof surface after re-roofing.

[Means to solve the problem]

In order to achieve this purpose, the reroofed horizontal roof of the present invention is a roof in which the existing thin roof tiles 1 are replaced with metal face plates, and the eave tips of the existing thin roof tiles 1 are elastically An eaves member 8 provided with a groove 8a for clamping and a locking portion 8f that elastically engages with the eaves side engaging portion 16a of the roof board 6.
is engaged with the tip of the eave of the existing thin roof tile 1, and has a width corresponding to the distance w between the steps of the existing thin roof tile 1, and a ridge having almost the same shape as the locking part 8f of the eave edge member 8. Roof plate 6 forming side engaging portion 16b
It is characterized in that the locking portion 8f of the eaves edge member 8 is locked to the eave side engaging portion 16a of the eaves side engaging portion 16a of the eaves side engaging portion 16a.

[Effect]

Various types of eave-edge members 8 with different depths of the grooves 8a and dimensions in the direction of the eaves ridge are prepared in advance, and at the time of construction, the eave-edge members 8 that match the dimensions and thickness of the existing thin roof tiles 1 are selected. , the groove 8 of this eaves member 8
At step a, the eave tips of the existing thin roof tiles 1 are engaged and clamped. Furthermore, a ridge-side engaging part 16b having almost the same shape as the engaging part 8f is formed on the engaging part 8f of the eaves edge member 8, and the distance between the steps of the existing thin roof tile 1 is w.
The eaves side engaging portion 16 of the roof board 6 has a width corresponding to
Engage the parts a and roof the roof in sequence from the eave side to the ridge side. As a result, there is no need to remove the existing thin roof tiles 1.
A roof can be reroofed without significantly increasing the thickness or weight of the roof as a whole.

Moreover, it can be installed without cutting the eave tip of the existing roof tile or adding plywood or arabesque, so it is easy to work with, and there is no appearance of discomfort between the eave tip and the roof surface, making it more aesthetically pleasing. A good roof can be obtained.

Moreover, since the roof plate 6 has a width corresponding to the step distance w of the existing thin roof tile 1, the gap between the existing thin roof tile 1 and the roof plate 6 is reduced, and the sound of rain does not echo.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Figures 2 and 3, 1, 1a to 1d
A normal tiled roof includes existing thin roof tiles such as slate tiles, and 4 is field timber or wooden rafters.

Roof sheets 6 are made of elastic metal plates, and these roof sheets 6 are formed by roll-forming or the like so that the dimensions in the eave ridge direction correspond to the distance w between each step of the roof tiles 1. A plurality of roof plates 6 are horizontally roofed by connecting them in the direction of the eaves so as to correspond to one row of roof tiles 1. A hanging portion 6b is formed at the eave side end of the roof board 6, and a folded portion 6c is formed from the lower end of the hanging portion 6b toward the ridge side.

Eave side engaging portion 16 of roof board 6 located on the eave tip side
a extends over the roof tiles 1c, 1d at the tips of the eaves, and a groove 8 of the eave edge member 8 is formed at the tips of the roof tiles 1c, 1d.
a is fitted.

As shown in FIGS. 2 to 4, the eaves member 8 has a long upper side 8b and a short upwardly sloping lower side 8c connected at an end side 8d, and these form a groove 8a, in which a roof tile is attached. The tips of the eaves 1c and 1d are elastically engaged and held. Furthermore, the eaves member 8
A hanging piece 8e with a folded part 8g is formed hanging from the short lower side 8c, and this hanging piece 8e hangs down so as to cover the tip of the eave.

8f is a locking portion provided at the upper end of the upper side 8b of the eaves edge member 8, and the shape of the locking portion 8f is designed to be approximately the same as the shape of the ridge side engaging portion 16b of the roof board 6. At the same time, it is fixed to field materials or rafters 4 via hangers 15 with fixing devices 7 such as nails or wood screws. And this locking part 8f
The eave-side engaging portion 16a of the roof board 6 is engaged with the eave-side engaging portion 16a, and the roof is successively raised from the eave side to the ridge side.

What is shown in FIG. 5 and FIG. 6 is another embodiment of the roof board 6 and the eave edge member 8 of the present invention. The shape of the side engaging portion 16b and the shape of the locking portion 8f of the eaves edge member 8, which is formed to have substantially the same shape, are different from the previous embodiment. That is, the roof board 6
A bent part 6d is formed at the end of the folded part 6c, and the ridge side engaging part 16b has a restraining protrusion 6h and an upward protruding part 6i formed above a groove 6g opening toward the eaves, and a fixing part 6h. 6j, a curved portion 6k is formed at the end of the fixed portion 6j. Then, the fixing part 6j is fixed to the rafter 4 with a fixing device 7 that penetrates the roof tile 1, and the folded part 6c of the roof board 6 located on the ridge side is inserted into the groove 6g and engaged elastically, and the restraining protrusion is inserted into the groove 6g. It is connected to the roof board 6 on the ridge side by being elastically supported by the portion 6h.

In each of the above embodiments, the longitudinally adjacent roof panels 6 and eaves edges 8 are connected to each other at their end portions via joints (not shown), as in the construction of conventional horizontal roofs. In addition, the eave edge member 8 can be formed as a bent product on-site by roll forming or the like according to the width or step size of the roof tile 1 in the same way as the roof board 6, or can be formed in advance by various groove depths or on an existing thin roof. The tiles are shaped in various ways according to the width of the tiles, and the edges 8d are positioned closer to the ridge than the center of the rain gutter so that rainwater can flow into the gutter accurately. Furthermore, the roof shingles 6 and the eaves member 8 are formed in a slightly curved shape so that the central part in the width direction thereof becomes convex toward the roof tile 1, thereby preventing mutual connection due to the springback effect. This is even more desirable since it becomes stronger and the degree of adhesion to the roof tile 1 also increases.

The horizontal roof of this embodiment configured as described above can be covered with roof plates 6 without peeling off the existing thin roof tiles 1 and without using new metal rafters, so that It requires less time and effort compared to other methods, and is extremely easy to work with.

In particular, by adjusting the depth of fit between the groove 8a of the eave edge member 8 and the roof tile 1, or by using a different dimension of the eave edge member 8 in the direction of the eave ridge, the eave edge member 8 can be made to fit perfectly with the existing thin roof tile 1. The distance between the steps of the existing roof tiles 1 can be adjusted based on this eaves member 8.
Since the roof panels 6 with widths corresponding to the width of the roof tiles 6 are sequentially laid down, the desired aesthetic appearance of the entire roof is not impaired, and furthermore, the roof panels 6 that match the steps of the roof tiles 1 are fixed. The strength as a horizontal roof is also perfect, and the air layer 1 generated between the existing roof tiles 1, the roof shingles 6, and the eaves member 8 is also improved.
You can reduce the rain noise by setting 3 to the minimum.

Moreover, this also eliminates the need to provide metal rafters on the existing roof tiles 1, which makes it possible to prevent an increase in the thickness of the roof and also to reduce the weight.

〔effect〕

The present invention has the above-mentioned configuration, and has grooves 8a that elastically sandwich the eave tips of the existing thin roof tiles 1.
Then, the eave edge member 8 provided with the locking part 8f that elastically engages with the eave side engaging part 16a of the roof plate 6 is engaged with the eave tip part of the existing thin roof tile 1, A roof plate 6 having a width corresponding to the distance w between steps of the roof tile 1 and forming a ridge-side engaging portion 16b having approximately the same shape as the locking portion 8f of the eaves edge member 8.
By locking the locking part 8f of the eaves edge member 8 to the eave side engaging part 16a of the roof, the thickness and weight of the roof as a whole can be increased without removing the existing thin roof tile 1. You can replace the roof without having to do so.

Moreover, it can be installed without cutting the eave tip of the existing roof tile or adding plywood or arabesque, so it is easy to work with, and there is no appearance discomfort between the eave tip and the roof surface, making it more aesthetically pleasing. You can get a good roof.

Furthermore, since the roof plate 6 has a width corresponding to the distance w between the steps of the existing thin roof tile 1, the gap between the existing thin roof tile 1 and the roof plate 6 is reduced, and the sound of rain does not echo. have an effect.
