Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a horizontal roof plate using thin metal steel sheet material etc. for constructing a horizontal roof structure in a building. This relates to the improvement of horizontal and grooved roof shingles, which makes it possible to replace and install a new horizontal roof structure by covering the entire surface of an existing roof structure that is covered with single roof tiles such as thin slate tiles. It is.

[Conventional technology]

Conventionally, roofs of buildings have structures using asbestos-based lightweight roof tiles, that is, so-called thin slate tiles.

However, this type of roof structure using thin slate tiles,
In general, due to the lack of building materials in the era, they were often constructed using slate tiles, which were relatively easy to construct and inexpensive, and therefore, roof structures of buildings belonging to the old era were often constructed using slate tiles. Due to the fact that the building is in such a state of deterioration, it is necessary to take some measures to prevent rain leaks and improve its appearance.

On the other hand, asbestos fiber, a mineral-based natural fiber that has been commonly used as a building material due to its excellent properties, has recently been recognized as having good weather resistance. It was found that the fibers on the external surface exposed to the atmosphere deteriorated and became brittle due to aging, and even in their natural state they gradually peeled off and fell off, scattering into the air. It has been confirmed that airborne fiber dust exists, and when you breathe this airborne fiber dust constantly,
It has been pointed out that there is a risk of causing undesirable damage to human health, such as the risk of inducing harmful lung cancer, and this is becoming a serious social pollution problem, and it is important to dispose of it as soon as possible. desired, and
In this regard, asbestos was used as the main material, which was hardened with mortar cement and molded. The thin pear slate tiles used in S were no exception, and it was desirable to replace them as soon as possible.

Also, in order to reroof and renovate an existing roof structure covered with thin slate tiles in a building, it is necessary to tear out and remove all of the thin slate tiles, and to replace them with The common method is to re-roof the roof structure using new roofing materials, but in this case.

Not only does it take a considerable amount of time to tear out the existing tiles, but on the other hand,
Since it is difficult to replace the roof structure with S while the target building is still in use, another method is to leave the existing roof structure untouched and replace it with S. Measures are taken to install a new roof structure on top.

In other words, one way to install a new roof structure on top of the existing roof structure is to install wooden rafters (for example, wooden rafters that will form the roof of a building), as shown in Figure 4.
1) is used as a base, and the entire surface is covered with roof base material (field board) (
2), and on this roof base material (2), individual slate tiles (3) are laid in a series in a desired arrangement so that their ends overlap each other. In the existing roof structure (A), the roof base material (5) is reinstalled by passing the metal rafters (4), which will serve as the base, over the top surface of the existing roof structure (^). This is a structure in which a new metal roof board (6) is installed on top of the roof, with insulation materials installed as necessary, and another one is:
As shown in Figure 5, the metal rafters (4) described above
, a new metal roof board (6) is directly roofed on top of the existing slate tiles (3) without providing a roof base material (5) or the like.

[Problem to be solved by the invention]

However, in the case of the conventional re-roofing method shown in Fig. 4 described above, a similar separate roof structure is installed in addition to the existing roof structure, so the roof is completely double-layered. As a result, the thickness of the structure becomes significantly thicker, making it unsightly due to the lack of balance in the appearance and form of the building, and the construction itself is relatively complex, troublesome, and time-consuming. Moreover, the weight of the entire roof structure will increase, which may cause problems with the strength of the existing pillar members of the building that supports it.

Similarly, with the conventional reroofing method shown in FIG. 5 described above, even if the disadvantages of the configuration in FIG. Because the tiles have deteriorated to such an extent that the individual slate tiles are not normally lined up as neatly as they were when the roof was first installed, they have been exposed to wind, rain, cold and heat for a long period of time. As a result of constant exposure to slight vibrations and shocks, the roofing pattern may be misaligned or tilted, or the tiles themselves may be warped, and new roofing may be installed directly on top of them. It does not blend well with the metal roofing sheets being raised, and lacks compatibility, and the newly installed metal roofing sheets often come loose from the slate curved surface, making it unable to fulfill its role as a roof. This caused many inconveniences.

This invention is an attempt to improve these conventional problems, and its purpose is to prevent damage to the appearance and form of the target building, or to unnecessarily increase the weight of the target building. The present invention is designed to be easy to construct without any problems, and to achieve effective adhesion to single roof tiles such as existing slate tiles and appropriate holding properties. It is an object of the present invention to provide a horizontal roof board for replacing an existing roof structure of this type and installing a new one.

(Means for Solving the Problem:!J) In order to achieve the above-mentioned object, the horizontal roofing board according to the present invention includes individual roof tiles, such as slate tiles, on the roof base material of a building. At least the ends are overlapped with each other by a predetermined overlap width to form a stepped end surface.
It has a roof structure that is raised in a series at a predetermined pitch in the direction of the eave ridge, and is used to install a new horizontal roof structure on the existing roof structure. With a cross-sectional width corresponding to the pitch interval, an eave-side molded part and a ridge-side molded part are formed on one side of the face plate and the ridge-side molded part on the other side. The side molding part is made to be able to be fitted and engaged, and at least the eaves side molding part has an abutment outer surface that abuts against the step end surface of the single roof tile on the rear side, and a contact outer surface of the abutment outer surface. A step interval corresponding to the thickness of the single roof tile is installed in between.
The roof tiles are arranged on the overlapping portions of the single roof tiles at each of the front and rear tiers, and are fixed to the roof base material through the overlap portions by fasteners. It is said that

In addition, in the horizontally ruled roof board, the eave side molding part includes a face edge part that is made by bending one side of the face plate part downward and hanging down, and a lower edge of this front edge part that is folded inward. The other side of the face plate part is folded upwardly and inwardly, and the outside of the bent part is abutted to make the outer surface, and the rear side is formed inside the molded part on the ridge side. An insertion engagement part into which the pressure welding insertion piece part can be inserted and engaged, and this insertion engagement part is again folded upward and outward to stand up, and if necessary, one side part of the face plate part on the rear stage side There is a step interval corresponding to the thickness of the single roof tile between the rising support part that supports the roof from the inside and the face plate part, and the lower end of this rising support part is bent and extended outward. It is formed by forming.

[For production]

That is, in this invention, the face plate portion of the horizontal roof plate on the front side is placed on the surface of the single roof tile on the front side in the existing roof structure, and the abutting outer surface is placed on the surface of the single roof tile on the rear side. By abutting against the step end surface, the movement of the rear single roof tile in the direction of the eaves can be restricted, and at the same time,
Along with this operation, the installation of the front side horizontal roof shingles is located at the overlap part -F where the individual roof tiles on the rear side and the 1n side are overlapped, so the same overlap is required. This installation is done by fixing the parts to the existing roof base material with native tools, and
It is possible to control the peeling effect of each single roof tile on the front side, and in this state, the ridge side molded part of the front side horizontal roof plate is exposed to the peeling effect of the rear side horizontal roof plate corresponding to the rear side single roof tile. By fitting and engaging the eaves side moldings and repeating this operation sequentially, the corresponding horizontal roofing plates for each level can be directly roofed as desired on the surface of the single roof tile for each level. It can be raised.

In addition, the engagement of the eave side molding part of the rear horizontally ruled roof board with the ridge side molding part of the front horizontally ruled roof board is on the surface of the single roof tile on the front stage, and the front side tank fI Place the face plate part of the roof tile, and with its abutted outer surface abutting against the step end face of the rear single roof tile, cover the former ridge side molded part from above, and place the latter eave side molded part. By simply inserting and engaging the pressure welding insertion piece into the insertion engagement part, each level of horizontal roofing sheets can be installed, and any misalignment of the individual roof tiles of each corresponding level can be completely corrected. This allows the roof to be built in one piece with good adhesion.

〔Effect of the invention〕

As detailed above, according to the present invention, individual single roof tiles such as slate tiles are overlapped with each other by a predetermined overlap width at least at their ends to form a stepped end surface on a roof base material of a building. It has a roof structure that is raised in a series at a predetermined pitch interval in the eave ridge direction, and in the horizontal roof plate used to install a new horizontal roof structure on the existing roof structure, the eave ridge With a cross-sectional width corresponding to the directional pitch interval, an eave-side molded part and a ridge-side molded part are formed on one side of the face plate and the ridge-side molded part on the other side, and for the ridge-side molded parts that are adjacent to each other, The eave-side molded part is capable of being fitted and engaged, and at least the eave-side molded part has an abutment outer surface that abuts against the step end surface of the single roof tile on the rear side;
A step interval corresponding to the thickness of the single roof tile is placed between this abutting outer surface and the R state side. & The overlapping part of the single roof tile of each tier on the danshu side is arranged at the overlap part-H, and through this overlap part, the mounting part is fixed to the roof base material by the fastening tool. By placing the face plate part of the horizontal roof plate on the front side on the surface of the single roof tile on the front side in the roof structure, and by abutting its abutting outer surface against the stepped end surface of the single roof tile on the rear side, This controls the movement of the rear single roof tile in the direction of the eaves, that is, the effects such as displacement, and at the same time, this operation also prevents the rear and front single roof tiles from overlapping each other. Since the parts for installing the front horizontal crease roof panels are located on the overlapping part, the parts can be attached to the existing roof base material through the overlap part using fasteners. It is possible to control the peeling action of the individual roof tiles on the rear side and the front side, and furthermore, in this state, the ridge molding part of the horizontally ruled roof board on the face side is applied to the single roof tile on the rear side. By fitting and engaging the eave side molding of the horizontal roofing board on the later stage and repeating this operation in sequence, the horizontal roofing of each corresponding stage can be directly applied to the surface of the single roof tile of each stage. The roof sheets can be firmly and integrally connected and roofed as desired.

In a new roof structure that is built on top of an existing roof structure, the surface of the existing single roof tile is essentially covered by the horizontal roofing sheets, so it is advantageous. Not only is the thickness of the entire roof structure sufficiently thinner than that of a conventional double structure, but also each horizontal roof plate in an individual row corresponds to each single roof tile in an individual row. By using this horizontal roofing board, especially in the area where individual roof tiles overlap on the front and rear sides,
It is possible to control the abutment by the outer surface of the abutment and fix the attachment with the fastening tool at the mounting part, which can be used in conjunction with the step interval, so there is no risk of damaging the external appearance, and there is no need to worry about damaging the appearance of the metal. With a simple structure, existing and new roof structures can be extremely strongly integrated without the need for rafters or the like, and the weight can also be significantly reduced.

In addition, in this horizontal roof board, there is a front edge part in the eave side molding part where one side of the face plate part is bent downward and hangs down, and the lower edge of this front edge part is folded inward. At the ridge side molding part, the other side of the face plate part is folded upwardly and inwardly, and the outside of the bent part is abutted to make the outer surface, and the rear part is formed inside. The insertion engaging part that can be inserted and engaged with the pressure welding insertion piece part on the side, and this insertion engaging part are again folded upward and outward to stand up, and if necessary, the face plate part on the rear side is inserted. A step interval S corresponding to the roughness of the single roof tile is provided between the standing L rising support part that supports the side part from the inside and the face plate part, and the lower end of this rising support part is bent and extended to the outside. The installation is done by forming a part on the surface of the single roof tile on the navigation stage side, and placing the face plate part of the horizontally ruled roof plate on the front stage, and also attaching the outer surface of the abutted part to the surface of the single roof tile on the rear stage side. In a state where the former ridge side molded part is covered from above while it is in contact with the step end surface, the latter eave side molded part is inserted and inserted, and the pressure welding insertion piece part is inserted and engaged with the insertion engagement part. With one simple and easy operation, the eave side molding part of the rear horizontally ruled roof board can be fitted and engaged with the ridge side molding part of the first stage horizontally ruled roof board with good workability.
In this way, by using the horizontal roofing boards of each tier, it is possible to completely control the displacement of the single roof tiles of each corresponding tier, and to make it possible to roof the roof tiles integrally with good adhesion on the surface of the single roof tiles. Furthermore, this horizontal roofing board itself has excellent features such as being extremely simple in construction, easily molded by roll forming, etc., and can be provided at low cost.
