Description

Description: TECHNICAL FIELD The present invention relates to a side-roof roof structure using a side-roof roof plate such as a sheet metal sheet material in a building, and more specifically, mainly to a thin slate roof tile. For existing roof structures that have been roofed with single roof tiles such as
The present invention relates to an improvement in a side-roof roof structure that is entirely covered with a side-roof roof plate.

[Prior Art] As a roof structure for a building, a lightweight single-piece roof tile made by using asbestos-based material as a main material and cementing it with cement or the like There is a structure that is soaked up by so-called thin slate roof tiles.

Then, the roof structure with this type of thin slate tile is
Due to the shortage of building materials, they were often constructed using slate tiles that were relatively easy to obtain and were inexpensive, and hence the roof structure of buildings belonging to the old age. However, the deterioration is also serious, and it is necessary to take some measures in order to prevent rain leaks and also in appearance.

On the other hand, asbestos fiber, a so-called asbestos, which is a mineral natural fiber that has been generally used because of its excellent properties in one aspect as a building material, has recently been shown to have weather resistance. Was found to lack
It has been confirmed that the fibrous portion of the outer surface exposed to the atmosphere gradually peels off even in a natural state due to aging and weakening due to aging, etc., and then scatters and floats in the air. When breathing this airborne fiber dust all the time, the risk of causing undesired damage to human health,
That is, for example, it has been pointed out that there is a risk of inducing harmful lung cancer and the like, which has become a serious social pollution problem and is desired to be abolished at an early stage. The slate roof tile made by using asbestos as the main material and solidifying it with mortar cement, etc. was by no means an exception, and it was desirable to replace it early.

Here, in order to renovate the existing roof structure that has been roofed with thin slate tiles in a building by renovating it, first remove all of the slate tiles by removing it, and replace it with It is common to use a new roofing material and re-roof the roof structure. In this case,
In addition to the considerable effort required to remove the existing slate roof tiles,
On the other hand, since it is difficult to re-roof the roof structure using the target building, as another method,
The existing roof structure will be left untouched, and it will be overlaid on this existing roof structure to build another roof structure.

That is, as one of means for newly constructing another roof structure on this existing roof structure, as shown in FIG. 4, for example, a wooden rafter used as a hut (roof) structure of a building.
The base material is (1), and the roof base material (field board) is used on the entire surface (2)
In addition to laying the roof tiles on the roof base material (2), arrange the individual slate roof tiles (3) on the ridge-side end so that the eaves-side ends overlap each other as expected. In the existing roof structure (A) constructed by raising it in series, a metal rafter (4) to be a mounting base is appropriately laid over the upper surface of this existing roof structure (A). A roofing base material (5) is laid, and if necessary, with a heat insulating material etc., a new metal roof plate is placed on top of these.
There is also a structure in which (6) is raised, and as another one, as shown in FIG. 5, the metal rafters (4), roof base materials (5), etc. are provided. Directly on the existing slate roof tiles (3) that have been raised
There is one that is constructed by roofing a new metal roofing plate (6).

[Problems to be Solved by the Invention]

However, in the case of the conventional thatching means shown in FIG. 4 mentioned above, in addition to the existing roof structure, a similar separate roof structure is newly constructed, so that the roof having a completely double structure is used. In addition, the thickness of the building is significantly increased, and the appearance and form of the building is not well-balanced, which makes it unaesthetic. In addition, the construction itself is relatively complicated and troublesome, and it is troublesome. In addition, since the weight of the entire roof structure is increased, there is a possibility that some problems may occur in the strength of the existing pillar members in the building that supports the roof structure.

Similarly, in the conventional reshuffling means shown in FIG. 5 described above, the slate tile itself in the existing roof structure needs to be repaired although the disadvantages in the structure of FIG. 4 are temporarily eliminated. Since it has been deteriorated to the extent that it usually does, the individual slate tiles are not regularly arranged as they were at the beginning of the roofing, and they are exposed to wind, rain, and heat for a long period of time, and As a result of constant micro-vibration, impact, etc., there is often a difference in the manner of thatching, tilting, etc., or the roof tile itself is warped, and it is newly added directly on this. ， It may not be compatible with the roofing metal roofing board and lacks compatibility, and this new roofing metal roofing board may often be released from the slate tile surface, and may serve as a roof. Such as disappearing It has been filed in which produce convenience.

The present invention is intended to improve such conventional problems, and its purpose is to impair the appearance and aspect of the target building, or to increase the weight more than necessary. It can be easily installed without the need for effective adhesion to the existing slate roof tiles of each row,
It is an object of the present invention to provide a lateral thatched roof structure of this kind, which is capable of achieving an appropriate holding property.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a lateral thatched roof structure according to the present invention has an individual roof tile such as a slate tile on a roof base material of a building, and an eaves-side end on a ridge-side end. Have an existing roof structure in which rows are roofed in a row at a predetermined pitch in the direction of the eaves so that they overlap each other with a predetermined overlapping width to form a step end surface. A roofing roof structure is newly constructed by hoisting a new roofing roofing board on top, and the cross-section width corresponds to the pitch pitch in the eaves direction, and the eaves side molding part on one side of the face plate part, the other side. The ridge-side molded part is formed on each of the parts, and the ridge-side molded parts that are adjacent to each other are provided with the side-roofing roof plate that allows the eaves-side molded part to be fitted and engaged. At least the ridge-side molded part of the plate has an outer surface folded back from the face plate part, and this outer surface is the step end. When each of the rows of roofing roofing boards is placed on the roof tiles of each row, the folding outer surface is brought close to the step end surface. In the state in which it is placed, the mounting part is fixed to the roof base and the rafter side through the overlap part and fixed up.

[Action]

That is, according to the present invention, the face plate portion of the eave-side roofing roofing plate is placed on the surface of the eave-side unit roof tile in the existing roof structure, and the folded outer surface is the eave-side unit roof tile. Only by bringing it close to the step end face of the building, without taking the trouble of arranging the position of the single roof tile at a predetermined position on the overlapping part where the individual roof tiles on the eaves side and the ridge side are overlapped, It is possible to position the attachment part of the side thatched roof panel.

In addition, by fixing and fixing this mounting portion to the existing roof base material, and eventually to the lumber through the overlapping portion with the fastener, the eaves side and the ridge side having these double weights It is possible to regulate the movement and peeling of single roof tiles. Moreover, even if there is a gap between the outer surface folded back from the face plate portion of the roof plate and the step end surface of the slate tile, this gap has an effect of absorbing the positional deviation of the slate tile.

Further, in this state, the eaves side moldings of the horizontal roofing board are fitted and engaged with the ridge-side moldings of the horizontal roofing roofing board, and by repeating this operation in sequence, It is possible to directly raise the corresponding thatched roofing boards for each step on the surface of the single roof tile.

The eaves side molding part (13) on one side and the ridge side molding part on the other side.
(14) is formed by being continuously formed.

Then, in the eaves side molding portion (13) of the lateral roofing roof plate (11), one side portion of the face plate portion (12) is bent downward by a predetermined length to form a front edge portion (21). Along with hanging down, the lower end edge (22) is bent and extended inward to form a pressure contact insertion piece (23), and a downward edge bend (24) is formed at the end.

Further, in the ridge-side molding portion (14), the other side portion of the face plate portion (12) is provided with a pressure contact insertion piece portion (2) including at least the edge bending portion (24).
It is folded back inwardly shorter than 3) to form an insert engagement portion (31) for inserting and engaging the press-contact insertion piece portion (23) including the edge bending portion (24), and again this is formed. ， Folding outward and rising up to stand up support part (32)
And the lower part of the rising support part (32) is left between the extension of the face plate part (12) and the space (t) corresponding to the thickness of the slate roof tile (3). Then, the attachment portion (33) is formed by being folded back and extended to the outside, and the upward edge bending portion (34) is formed at the end portion thereof.

Also here, these eaves side molding part (13) and ridge side molding part (14)
As will be described later, the gap dimension between the pressure contact insertion piece portion (23) and the insertion engagement portion (23) at both adjacent eaves (13) and (14), as will be described later. In the state where they are engaged with each other, the space dimension between the folded outer surfaces (31a) of the insertion engaging portions (31) on the eaves side and the ridge side is the slate roof tile (3). Dimension (P) of the eaves ridge direction minus the overlap width (l)
-l), and in this engaged state,
When the folded outer surface (31a) of the insertion engagement part (31) is brought close to the step end surface (3a) of the overlapping part (b) of the slate roof tile (3), the attachment part ( At least a part of (33) should be matched so as to correspond to the mutual overlap (b) in each slate roof tile (3), and at this time, the ridge-side forming part (14) of the roof board should rise. The support part (32) allows the part of the face plate part (12) close to the eaves side molding part (13) to be supported from the back side, so that the load applied from the outside to this face plate part (12). It is preferable to reduce the load.

And, using the horizontal roofing board (11) by the above structure, to the roof of the existing roof structure (A), to roof the new roof structure (B), as described above, each individual slate tile
Regarding the existing roof structure (A) in which (3) was raised so that its ends overlap each other, first, a horizontal thatched roof plate (11) was placed on the slate tile (3) on the ridge side. Face plate part of the ridge side
(12) is placed directly, and the folded outer surface (31a) of the insertion engagement part (31) in the ridge-side molding part (14) is overlapped with the eave-side slate roof tile (3). Position it close to the front end face (3a) which is a step.

As a result of the positioning arrangement of the roofing roof panel (11) on the ridge side, the attachment part (33) on the ridge side molding part (14) in contact with the upper surface of the slate tile (3) on the eaves side has these The slate roof tiles (3) on the eaves side and the ridge side are automatically positioned on the mutual overlapping part (3b), and in this state, the mounting part (3
By pressing 3) downwards comparatively strongly,
By using a fastener (C) such as a tapping screw, the roofing board (11) on this eave side is used as a roof base material (2), and by extension, wooden rafters.
Since it can be fixed and fixed to (1) very easily, the fixing operation of the mounting portion (33), and by extension, the face plate (1
With the installation and fixing of the thatched roof panel (11) including 2), even if these slate roof tiles on the eaves side and the ridge side have overlapping portions,
Even if (3) is misaligned or warped, it can be pressed from above and held in that position. More movement than the roof tile (3) itself, or
The peeling action can be effectively regulated.

Next, for the ridge-side forming part (14) of the lateral thatched roof panel (11) fixed and attached in this state, the lateral thatched roof panel (11)
The eaves side molding part (13) is fitted from above, and the former press-fitting insertion piece part (23) is inserted into and engaged with the former insertion engagement part (31), so that the insertion is also possible. Outer surface at engaging part (31)
(31a) is positioned close to the step end face (3a) of the next eaves-side slate roof tile (3), and then, similarly to the above, the mutual overlapping portion (3b) of each slate roof tile (3). ) It is only necessary to attach and fix the attachment part (33) to the roof base material (2) and the wood rafters (1) using the fasteners (C) above, and by repeating the above operation, the existing roof structure ( On the surface of each individual slate roof tile (3) that constitutes the roof surface in (A), a row of roofing roof boards (11) corresponding to each row is adhered to each, and these are attached to the existing roof base material (2). ), And by that, it can be pushed up while being pressed and held by the wooden rafters (1), which makes it possible to easily construct the newly constructed roof structure (B) in a side-roofing manner as expected.

Therefore, in the state that the new roof structure (B) is raised on the existing roof structure (A) as described above, all the single slate roof tiles (3) in the existing roof structure (A) are By the lateral thatched roof boards (11) engaged adjacently corresponding to the individual rows, the existing roof base material (2) and by extension, the wooden rafters (1) are tightly pressed and held, and each row is As a result, the new roof structure (B) firmly integrated with the existing roof structure (A) can be raised with good workability and extremely easily.

In addition, in the above-mentioned embodiment configuration, the present invention has been described with respect to a case where a roofing structure is newly constructed and replaced by a roofing roof plate on an existing roof structure using slate tiles. It is needless to say that the present invention can be applied not only to the structure but also to an existing roof structure such as a cement roof tile, and the same action and effect as the above can be obtained.

〔The invention's effect〕

As described above in detail, according to the present invention, individual roof tiles such as slate tiles are provided on the roof base material of the building, and the eaves-side end portion has a predetermined overlapping width on the ridge-side end portion. Has an existing roof structure that is made up of a series of rows with a predetermined pitch pitch in the eaves ridge direction so that they overlap to form stepped end faces.A new roof structure is added to this existing roof structure. In a new thatched roof structure that is constructed by hoisting a horizontal thatched roof board, the cross section width corresponds to the pitch interval in the eaves side direction, with the eaves side molding part on one side of the face plate part and the ridge side molding part on the other side. And a side-roof roof plate that allows the eaves-side moldings to be fitted and engaged with the ridge-side moldings that are adjacent to each other,
At least the ridge-side forming part of this roofing roof plate is formed with an outer surface folded back from the face plate part and a mounting part which is located on the overlap part when the outer surface is brought close to the step end surface. Therefore, on the surface of the single roof tile on the ridge side of the existing roof structure, place the face plate part of the roofing roofing board on the ridge side, and turn its outer surface to the step end surface of the single roof tile on the eaves side. Just by bringing them close to each other, the roof board mounting part can be placed on the overlapping part of the roof tiles on the eaves side and the ridge side without any trouble such as restricting the position of the roof tiles to a predetermined position. Can be easily located.

Furthermore, by fixing and fixing this attachment part to the existing roof base material, and eventually to the lumber through the overlapping part with the fastener, the movement and separation of the individual roof tiles on the eaves side and the ridge side can be achieved. Can be reliably regulated. In addition, even if there is a small gap between the outer surface folded back from the face plate portion of the roof plate and the step end face of the slate tile, this gap can absorb the positional deviation of the slate tile.

Further, in this state, the eaves side molding part of the roof board is fitted and engaged with the ridge side molding part of the roof board, and by repeating this operation in sequence, the unit roof tile of each step is It is possible to directly raise the corresponding thatched roof shingles on the surface as expected.

In addition, since the new roof structure that is roofed on the existing roof structure in this way is a structure that only substantially covers the surface portion of the existing single roof tile with the thatched roof plate,
The overall thickness of the obtained roof structure is sufficiently thin as compared with the conventional double structure, and there is no fear of impairing the external appearance or giving an extra weight load.

In addition, each roof tile of each row is made to correspond to each roof tile of each row, and the fasteners at the mounting portion are provided through the overlapping portion of each roof tile on the eaves side and the ridge side. Since it is mounted and fixed, it is possible to integrate the existing and new roof structures extremely strongly without the need for intervening metal rafters, etc., and also to reduce the weight sufficiently. In addition, it has an excellent feature that it can be easily lifted up and the workability can be remarkably improved, and that the overall structure is simple, easy and inexpensive to carry out.
