Description

Description: <Industrial application> The present invention relates to a roof reed changing method for a building in which an existing roof surface is replaced with a new roof plate.

<Prior Art> Conventionally, in order to replace the existing roof surface with a new roof plate, the existing roof surface is peeled off and repaired, and then a base material is laid and a new roof plate is roofed.

However, the above-mentioned conventional method for changing the roof takes a great deal of time and labor, is expensive, and has a problem in that it cannot be used in a building at the time of work in view of the fall of dust and the danger, and the like. It was a perfect score.

Therefore, in order to solve that point, a means for fixing a new roof plate to the existing roof surface without peeling or repairing the existing roof surface is disclosed in, for example, Japanese Patent Publication No. 60-13097. It is disclosed.

<Problems to be Solved by the Invention> The above-described invention fixes the support material configured in a hat shape on the existing roof surface, and by roofing the roof plate in an orthogonal shape on the upper surface of the support material, very easily, Moreover, the roof can be changed without peeling off the existing roof surface, and it has a certain effect.

However, since the hat-shaped support material has to be fixed to the existing roof surface, the material cost, labor, and the dissatisfaction remain. Also, if the roof plate is formed of a thin metal plate, since it has no strength, the roof plate may be crushed by the load acting on the upper surface when a worker walks on the roof or when it is snowing. is there. Therefore, there is a demand for a method for changing the roof surface of an existing roof so that the roof changing work and the structure are extremely simple and the strength is high.

<Means for Solving the Problems> The present invention has been proposed in order to solve the above-mentioned conventional problems and to cope with the demands from the related art. On the existing roof surface provided on the above, the hard base member is disposed on the lower surface of the metal plate, and the downward locking portion is formed at the front end and the upward engaging portion is formed at the rear end by bending, respectively. Of the roof plate located on the lower side of the slope is fixed to the protruding part of the existing roof surface, and the roof plate located on the upper side of the slope is locked. Part is locked to the engaging portion of the roof plate located on the lower side of the slope fixed to the protruding strip, and the front lower surface of the hard base member of the roof plate on the upper side of the slope is engaged with the roof plate on the lower side of the slope. Related to a method for changing roofing of a building characterized by being directly supported on the upper surface of the part Is.

<Operation> Since the present invention has the above-described configuration, a plurality of new roof plates are provided from the eaves of the existing roof surface toward the ridge by using the plurality of parallel protruding strips that are usually provided on the existing roof surface. It can be fixed sequentially, and in particular, because a hard base member is placed on the lower surface of the roof plate, it is possible to secure sufficient pressure resistance against mechanical strength and the load acting on the upper surface. The lower surface of the front end of the member is directly supported by the upper surface of the engaging portion of the roof plate located on the lower side of the slope, so that not only is it stable, but the vertically adjacent roof plates are firmly engaged with each other and rainwater is blown in. It does not seep into the attic due to the dull-capillary phenomenon, and at the time of construction, the hard base member can be secured simply by engaging the engaging part of the lower roof plate so as to cover the engaging part of the upper roof plate. Because it is supported, the hard base material is Even if it is separated or integral with the root plate, it is possible to work extremely easily and surely.

<Examples> The present invention will be described below with reference to the drawings of the examples.

As the existing roof 1 that can be used for the thatch changing method of the present invention,
A plurality of protruding ridges 2 are provided in parallel along the inclination direction of the roof surface.

As such an existing roof 1, for example, if the roof bar is a roof tile roof as shown in FIG. 4, the protruding strip 2 is a roof bar, and if it is a corrugated sheet or a folded roof as shown in FIG. Article 2 is Yamabe.

Therefore, in the existing roof 1, a plurality of protruding strips 2 along the inclination direction are formed in parallel by the wave peaks of the roof tile bar.

Next, the roof plate 3 used in the present invention is formed by bending the locking portion 4 downward at the front end along the length direction and bending the engaging portion 7 upward at the rear end. .

The roof plate 3 in the embodiment shown in the drawings is made of copper, aluminum,
On the lower surface of the metal plate 14 formed of stainless steel or the like, a hard foundation member 15 made of wood wool cement plate, a plate material made of plywood, etc. is arranged, and the hard foundation member 15 not only provides heat insulation and a sound deadening effect. By superimposing on the metal plate 14, the metal plate 14 is reinforced and the construction is easy.
In this case, the metal plate 14 and the hard base member 15 may be integrated in advance with an adhesive or the like, or may be polymerized at a construction site.

Then, the engaging portion 4 and the engaging portion 7 are provided on the front end and the rear end of the metal plate 14, respectively.
And are preformed by bending along the length direction.

The locking portion 4 of the roof plate 3 shown in the embodiment of FIG.
Has a U-shaped cross section in which a front end of the front end of the front end piece 5 extends downward at a right angle and a lower surface piece 6 is further bent rearward. In addition, the engaging portion 7 has an upper end of a rising piece 8 that stands upright at the rear end of the metal plate 14 as an engaging piece 9 that is bent forward in a superposed manner, and the tip of the engaging piece 9 is bent upward. To form the contact piece 10, and further, the end of the contact piece 10 is inverted to form a fastening piece 11 extending rearward.

The roof plate 3 having such a configuration is arranged so as to be orthogonal to the projecting ridges 2 of the existing roof 1, and the rear end engaging portion 7 of the roof plate 3 is provided on the projecting ridges 2 via the fastener 13 such as a nail. And the engaging portion 7 is engaged with the engaging portion 4 at the front end of the roof plate 3 located on the upper side of the slope, and the lower surface of the front end of the hard base member 15 of the roof plate 3 on the upper side of the slope is inclined. The lower roof plate 3 is directly supported by the upper surface of the engaging portion 7, and the plurality of roof plates 3 are sequentially fixed from the eaves of the existing roof 1 toward the ridge.

That is, with respect to the lower roof plate 3 on the eaves side fixed via the fastener 13, the front end of the upper roof plate 3 on the ridge side is locked to the rear end of the lower roof plate 3. Will be done.

To fix the engaging portion 7 at the rear end of the roof plate 3 to the protruding strip 2,
For example, the fastening piece 11 of the engaging portion 7 extending rearward is brought into contact with the upper surface of the protruding strip 2 of the existing roof 1, and the fastening tool 13 is attached to the fastening piece.
It suffices that it penetrates 11 and is driven into the protruding strip 2, but the hanger may be fixed without using a fastener such as a nail.

For the lower roof plate 3 with the engaging portion 7 fixed to the protruding strip 2,
The engagement state between the engagement portion 7 and the engagement portion 4 when fixing the upper roof plate 3 is clear from the drawings. That is, below the engaging piece 9 in the engaging portion 7 of the lower roof plate 3, the lower surface piece 6 in the engaging portion 4 of the upper roof plate 3 is engaged from the front, and the tip is raised. The lifting piece 8 is fitted and engaged until it abuts.

At this time, the upper end of the contact piece 10 has a hard base member 15 of the roof plate 3.
It directly abuts the bottom surface of the roof from below to support the roof plate 3, thereby reinforcing the engaging portion between the engaging portion and the engaging portion, stabilizing the hard base member, and, for example, strong wind. Sometimes rainwater does not seep out into the attic even if it blows in from the locking part.

In the embodiment shown in FIG. 1, the front end piece 5 of the upper roof plate 3 is in direct contact with the upper surface of the rear end portion of the lower roof plate 3. With this configuration, although the structure is simple, there is a risk that rainwater may enter the upper roof plate 3 due to the capillary phenomenon.

Therefore, in the embodiment of FIG. 2, the rear end engaging portion 7 of the roof plate 3 is
A step-shaped step piece 12 is provided at the start-up piece 8 in the above, and the front end piece 5 of the upper roof plate 3 is brought into contact with the upper surface of the step piece 12 to prevent rainwater from entering.

Further, the front end of the lowermost roof plate 3 is fixed to the eaves. As a means for this in FIG. 3, the locking portion 4 of the roof plate 3 is a part of the locking metal fitting 17 fixed to the eaves. I am trying to fix it.

As a result of the front end of the upper roof plate 3 being locked to the rear end of the lower roof plate 3, there is a space 16 between the roof plate 3 and the existing roof 1.
Is formed, which has the effect of heat insulation and noise reduction. Even with this structure, since the roof plate 3 has the double structure of the metal plate 14 and the hard base member 15, sufficient strength can be secured.

Although the present invention has been described with reference to the embodiments of the drawings, the present invention is not limited to the above-described embodiments and can be carried out in any manner as long as the configuration described in the claims is not changed. Is.

<Effects of the Invention> In short, according to the present invention, the hard base member is arranged on the lower surface of the metal plate on the existing roof surface provided with a plurality of protruding ridges in parallel along the inclination direction, and the front end faces downward. The locking parts are arranged so that the roof plates, each of which has an upward engaging part bent at the rear end, are formed so as to be orthogonal to the projecting ridges of the existing roof surface, and the locking parts of the roof plate located on the upper side of the slope. Is locked to the engaging portion of the roof plate located on the lower side of the slope, and the front end lower surface of the hard base member of the roof plate on the upper side of the slope is directly supported by the upper surface of the engaging portion of the roof plate on the lower side of the slope. It is characterized by having done.

Therefore, there is no need to remove the existing roof surface for repairing or laying a new base material, etc., and just hit the fasteners on the existing protruding strips, which saves a lot of trouble and requires re-roofing. The required work period can be significantly shortened. Further, in particular, the hard base member of the present invention is thinner than the base material of the conventional example, so the front end lower surface of the hard base member of the upper inclined roof plate is directly supported by the upper surface of the engaging portion of the lower inclined roof plate. By doing so, the hard base member will be stable, it will not rock or shift due to natural conditions such as rainstorms, and the locking part between the locking part and the locking part will be significantly reinforced Even if a person walks, it does not collapse. Furthermore, the roof plates that are vertically adjacent to each other are firmly engaged with each other so that rainwater does not blow into the roof and does not seep into the attic due to the capillary phenomenon. Since the hard base member is supported only by locking so as to cover the locking portion of the upper roof plate, it is extremely easy to separate the hard base member from the roof plate or to form an integral structure. , Can work reliably. Moreover, at the time of construction, the lower surface of the hard base member of the roof plate located on the upper side of the slope can be replaced by the locking part of the roof plate located on the upper side of the slope by simply locking the engaging parts and the engaging parts of the roof plates adjacent to each other. Since it can be directly supported on the upper surface of the engaging portion, there is no need to interpose other members, etc., and a roof that can be used effectively for a long period of time is robust and stable and does not require labor. It has many excellent practical effects such as easy construction.
