Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to horizontal roofing sheets made of metal steel sheets, and more particularly, to long metal steel sheets of a predetermined width that are coated with baking paint for rust prevention. This invention relates to an improvement of a horizontal roof board in which eave-side and ridge-side engagement portions having predetermined cross-sectional shapes for mutual engagement are formed in advance at both end portions of the roof sheet.

[Conventional technology]

BACKGROUND ART Conventionally, many types and aspects of horizontal roofing using long metal steel plates have been proposed and put into practice. Among them,
There is a lot of research and development going on to improve the rain protection at the ridge-side and eave-side engaging parts.

In particular, regarding the eave side and ridge side engaging parts of this type of horizontal roofing board, by bending and forming both ends of the long metal steel plate material into various shapes,
A mutually lockable engagement or locking shape, or a fitting or insertion shape, or a combination structure thereof is constructed, thereby obtaining effective and proper connection and connection and good rain closure. That's what I do.

[Problem to be solved by the invention]

However, in the case of conventional horizontal roof plates and horizontal roof structures made of long metal steel plates constructed in this way, a connection shape in which each engagement part on the eave side and ridge side is bent is adopted. As a result, the structure itself inevitably became more complex. As a result, on the one hand, there was a problem that the molding accuracy was lowered due to the difficulty of molding, and the desired functions and effects could not be obtained.

On the other hand, regarding the long metal steel sheet material that has a predetermined standard width, in order to form each engagement part on the eave side and ridge side, the proportion of the width dimension will increase relatively. The ratio of the face plate portion used for the original roof surface structure was reduced, resulting in an increase in material costs and an uneconomical problem.

Moreover, as the structure of each engaging part on the eave side and ridge side becomes larger and the difference in level at the engaging part becomes larger, the resistance to wind and rain blown up along the roof surface increases, resulting in the engaging connection part becoming larger. Problems have also arisen, such as an increase in rainwater infiltration, and a loss of flatness of the roof surface.

Furthermore, with this type of long metal roof plate, the intervention of the sacrificial plate member at the connection part of the roof face plate, and the engagement connection at the engagement part of the previous and next stages are attached to the rafter side at predetermined intervals. It is an essential requirement to intervene with a suspender member to allow the wearer to hang, but in the case of the conventional structure, the material of this waste plate member and suspender member is a relatively thick and highly rigid material. is used, its flexibility and elasticity are low, and therefore it does not fit well with the roof plate, and due to the intervention of waste board members and hanger members, unfavorable gaps may occur at the engagement connection part of the roof plate. There was a problem in that there was a risk of this occurring.

An object of the present invention is to solve the above-mentioned problems, and to provide a shape and structure in which the engaging parts on the eave side and the ridge side can be easily and compactly formed, and there is no waste in cutting out the material. Furthermore, it is an object of the present invention to provide a horizontal roofing board which can be adapted well to the intervention of sacrificial board members and hanger members.

[Means to solve the problem]

In order to achieve the above object, the horizontal roof board according to the present invention has a face plate part 2 in the longitudinal center of the metal steel plate, and an eave side engaging part 3 and a ridge side engaging part on both sides of the face plate part 2. The roof plate 1 has a horizontal part 4, and the eave side engaging part 3 of the ridge side roof plate 1 is engaged with the ridge side engaging part 4 of the eave side roof plate 1 to form a horizontal roof. In the roof board, a relatively thin long thin metal plate with high flexibility and elasticity is used as the material, and the eave side engaging part 3 has one side of the face plate part 2 bent downward. The hanging part 5, the contact pressure piece part 6 with the lower edge of the hanging part 5 bent toward the ridge side, the rising part 7 with the rear end of the contact pressure piece part 6 raised up, and the rising part 7 bent toward the ridge side. A holding part 8 is formed by bending the holding part 8, and a folded part 9 is formed by folding back the extended end of the holding part 8. a stepped portion 10 facing the rising portion 7;
, an engaging holding part 11 capable of engaging and holding the folded part 9 including the end part of the holding part 8, and an engaging holding part 11.
a support portion 12 extending diagonally inward and forward upward from the support portion 12;
Support receiving portions 13 at the ends which are supported by the supporting portions 12 in a flexible manner are formed respectively.

[Effect]

Therefore, in the horizontal roof board according to the present invention, the ridge side engaging part 4 of the eave side roof board 1 is made to cover the eave side engaging part 3 of the ridge side roof board 1 from above. , while pressing the support part 12 with the face plate part 2 of the ridge side roof board 1, insert the end of the holding part 8 of the eave side engaging part 3 into the engaging holding part 11 of the ridge side engaging part 4. By inserting the folded part 9 including the folded part 9 along the introduction surface of the support part 12 and abutting and engagingly holding the folded part 9, the contact pressure piece part 6 is attached to the face plate part 2 of the roof board 1 on the eave side. Can be placed under pressure on top. Therefore, irrespective of the presence of the suspender member 22 or the like, the contact pressure piece 6 is brought into precise surface contact with the face plate 2, so that the ridge-side engaging portion 4 and the eave-side engaging portion 3, a strong and stable engagement structure can be obtained.

〔Example〕

Hereinafter, one embodiment of the horizontal roofing board according to the present invention will be described in detail with reference to FIGS. 1 and 2.

FIG. 1 is a partially cutaway perspective view showing the general structure of a horizontal roof board according to this embodiment, and FIG. 2 is an enlarged sectional view of an engaging portion of the same roof board.

In Fig. 1, 1 is a roof plate, and the material of this roof plate 1 is a long metal steel plate of a predetermined width and a predetermined unit length, which is coated with baking paint for rust prevention, and has flexibility and A relatively thin material with high elasticity is used. Specifically, a long thin metal plate with a thickness of about 0.6 mm is used. Using a roll forming machine or the like, this long thin metal plate is continuously formed into an eave side engaging part 3 on one side and a ridge side engaging part 4 on the other side, leaving the face plate part 2 in the center along the longitudinal direction. let

The eaves side engaging part 3 has one side of the face plate part 2 bent downward by a predetermined length to form a hanging part 5 on the front part, and the lower edge thereof is bent inside and rearward. The contact pressure piece part 6 is formed by bending it. Furthermore, the rear end of this contact pressure piece 6 is 3/5 of the height of the hanging part 5.
It is raised up to a certain height to form a rising part 7, and further bent inward and rearward to extend the holding part 8, and a downward folded part 9 is provided at the extended end.

In the ridge-side engaging portion 4, the other side of the face plate portion 2 is raised lower than the rising portion 7 to form a stepped portion 10, and the upper end edge of the stepped portion 10 is raised outwardly and rearward. By folding it upward and inward, the folded part 9 including the end of the holding part 8 is formed.
An engaging and holding portion 11 is formed that can engage and hold. Furthermore, a support part 1 is provided with a support part 12 that also serves as an introduction surface extended and protruded from this engagement holding part 11 diagonally forward and upward inwardly, and a downward folded part 14 is provided at the end.
form 3. Therefore, the support receiving part 13 is supported by the support part 12 in a flexible manner.

Below, horizontal roofing board 1 configured as above
We will explain how to raise a roof using this method.

Rafters (not shown) are arranged on the main roof material along the roof slope, and the eave-side engaging portion 3 of the eave-side roof board 1 is appropriately fixed onto the rafters as shown in Fig. 2. The ridge-side engaging portion 4 of the roof shingle 1 is engaged and connected to the eave-side engaging portion 3 of the ridge-side roof shingle 1 so as to cover it from above, and this engaging connection is made sequentially from the eave side to the ridge side. By repeating this process, the desired roof structure can be obtained.

That is, the face plate part 2 covers the ridge-side engaging part 4 of the eave-side roof board 1 from above, and the eave-side engaging part 3 of the ridge-side roof board 1 is covered from above. While pressing the support portion 12 extending upward, the eaves side engaging portion 3 is inserted into the engaging holding portion 11 of the ridge side engaging portion 4.
The folded part 9 including the end of the holding part 8 is attached to the supporting part 1
It is inserted along the introduction surface of 2, and is engaged and held so that they butt against each other. Therefore, the contact pressure piece portion 6 is attached to the face plate portion 2 of the eave side roof panel 1.
This results in surface contact with the surface of a predetermined width, resulting in a strong and stable engagement structure.

Then, a sealed first depressurized space 25 is formed inside the structure via the first pressure contact portion 24 between the face plate portion 2 of the eave side roof plate 1 and the contact pressure piece portion 6, and at the same time A second depressurized space 27 is formed through a second pressure contact portion 26 between the face plate portion 2 of the ridge roof plate 1 and the support receiving portion 13.

Therefore, the intrusion of rainwater from the outside during windy weather or the intrusion of fine dust etc. is prevented by the first contact pressure part 24 which is in surface contact. but,
Even if it enters the first depressurized space 25 through this first pressure contact part 24, there will be a step raised from the face plate 2 of the eave side roof board 1 inside the first depressurized space 25. Since the stepped portion 10 is formed, the step is blocked by the stepped portion 10.

Furthermore, in this configuration, the height of the hanging portion 5 can be set relatively low, so that the overall appearance on the roof surface can be made extremely sleek.

〔Effect of the invention〕

Since the present invention has the above configuration, it has the following excellent effects.

First, while covering the eave side engaging part 3 of the ridge side roof board from above with the ridge side engaging part 4 of the eave side roof board 1, simply insert the end of the holding part 8 into the engagement holding part 11. A horizontal roof board can be constructed by simply hooking and fitting the folded folded parts 9, and engaging and holding them, resulting in excellent workability.

Further, as the support receiving part 13 formed at the end of the support part 12 is bent by the face plate part 2 of the ridge side roof board 1, the contact pressure piece part 6 is applied to the face plate part 2 of the eave side roof board 1.
The folded portion 9 including the end portion of the holding portion 8 is firmly engaged and held within the engaging holding portion 11 so that a strong and stable engaging connection structure can be constructed.

In addition, since a relatively thin elongated thin metal plate with high flexibility and elasticity is used as the raw material for the roof board, it is easy to fit in with the sacrificial board member and the hanger member.

Furthermore, after the connection and coupling, the first contact pressure part 24 prevents rainwater and dust from entering from the outside, and prevents rainwater entering due to capillary action etc. to the first contact pressure part 24.
Intrusion is prevented by the stepped portion 10 raised from the face plate portion 2 into the depressurized space portion 25 .

Furthermore, since the protrusion height of the entire structure can be set relatively low, the resistance effect against wind and rain pressure is reduced and its influence can be effectively eliminated. Furthermore, in terms of appearance, it is possible to create an extremely clean form by simply creating a horizontal step line corresponding to the protrusion height. In addition, the structure itself is simple and easy to process, and there is no waste in cutting out the material.
