Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to horizontal roofing sheets made of metal steel sheets, and more specifically, anti-corrosion baking is performed on long metal steel sheets of a predetermined width that are coated with paint or the like. It is a horizontal roof board in which engagement parts on both sides of the eaves are formed in advance in a predetermined cross-sectional shape for mutual engagement, and in particular, each engagement between the nine eave sides This relates to the improved structure of the section.

[Prior Art] ゛Many types and configurations of horizontal roof panels using long metal steel plates have been proposed in the past. There is active research and development aimed at improving the engagement and connection at the eaves and the rain closure, that is, improving the connection effect at the molded parts between the eaves and one building side, and preventing the infiltration of rainwater.

This is the eave side of this type of horizontal roof shingle.

Regarding the molded part on the ridge side, the shape of the connection between the remolded parts,
The focus of research and development is on improving the structure, and in normal cases, both ends of a long metal steel plate are bent into various shapes to form an engagement that can be engaged with each other. A locking shape, a fitting shape, a fitting shape, or a combination thereof is configured to achieve the desired effective and proper connection and connection and good rain protection. It is.

[Problem that the invention seeks to solve]

However, in the case of conventional horizontal roof plates made of long metal steel sheets, and even horizontal roof structures constructed in this way, a connection shape is used in which a bend is formed on both molded parts of one eave side and one ridge side. As a result, the structure itself inevitably becomes extremely complex, which not only makes molding difficult, but also reduces molding accuracy and does not always work as expected. .

There is a regret that the effect cannot be obtained, and on the other hand, the width dimension occupancy rate for forming the forming part increases relatively to the long metal steel sheet material that has a predetermined standard width. , the ratio of the width dimension part that is originally used for forming the roof surface is reduced, and as a result, there is a tendency to waste material when cutting out the planks.
Moreover, the structure of the molded part has also become larger, and the step between the front side and the rear side has become relatively thick, increasing the resistance to wind and rain blowing up along the roof surface. There are disadvantages such as increased risk of flooding and loss of flatness of the roof surface.

Furthermore, in this type of long roof sheet, as is well known, the intervention of so-called sacrificial sheet members at the joints between adjacent longitudinal ends, and also at the molding parts on the front and rear sides. This is for attaching and fixing the engagement connections to the rafter side at predetermined intervals.

The intervention of so-called hanger members is an essential requirement in each case, but in the conventional case described above, the long metal steel plate material is
Relatively thick. Therefore, materials with high rigidity and, in turn, materials with low flexibility and elasticity are used to maintain the mutual connection form of the molded parts, which does not fit well with each of the intervening members, making it difficult for the intervention to occur. This has resulted in problems such as the risk of creating an undesirable gap in the engagement connection portion.

Therefore, it is an object of the present invention to have a shape and structure that is as simple and compact as possible and that is easy to mold, and that eliminates waste in cutting the material. In addition, it is an object of the present invention to provide this type of horizontal roofing board that is compatible with the intervention of sacrificial board members and hanger members.

[Means for solving problems]

In order to achieve the above object, the horizontal roof board according to the present invention has a face plate part formed in the longitudinal center of a long metal steel plate, and molded parts on each of the eave side and nine ridge sides formed on both sides of this face plate part. In a horizontal roof board that forms a horizontal roof by connecting the eave side molding part on the previous stage to the ridge side molding part on the next stage side,
A relatively thin long thin metal plate with high flexibility and elasticity is used as the material, and the eave side molded part has a front end edge part formed by bending one side part of the face plate part downward, and a front end part. A contact pressure piece portion in which the lower edge of the edge is bent inward and rearward, a rising portion in which the rear end of the contact pressure piece is raised up, a holding portion in which the rising portion is bent and extended inward and rearward, and a holding portion. A folded part is formed by folding back the extended end of the part, and the other side part of the face plate part is raised up on the ridge side molded part, and a stepped part opposite to the raised part is formed. Fold the upper edge of the section outward and fold it back upwards inward.

an engaging holding portion capable of engaging and holding the folded portion including the end portion of the holding portion; and the face plate portion protruding diagonally forward and upward from the engaging holding portion and supported under free elasticity.

Alternatively, a resilient support portion that contacts the sacrificial plate member and the hanger member from below is formed, respectively.

[For production]

That is, in this invention, the front ridge side molded part covers the next eave side molded part, and the end of the holding part of the ridge side molded part is inserted into the engaging and holding part of this eave side molded part. The included folded portion is inserted along the introduction surface of the resilient support portion extending diagonally forward and upward, and is abutted/engaged and held, thereby forming a connection and coupling structure. Irrespective of the intervention of the suspender member, it is possible to maintain a good and strong seal by bringing the retaining parts into strong elastic contact with each other.

The eave side molded part (3) of the next horizontally ruled roof board (1) on the ridge side is engaged and connected to the molded part (0), and this engagement and connection is repeated sequentially from the eave side to the ridge side. In this way, the desired horizontal roof structure is obtained.

Now, to describe the aspect of the engagement and connection in more detail, the front ridge side molded part (4) is made to cover the next eave side molded part (3), and this eave side molded part ( In the engaging holding part (11) at 3), the holding part (8) at the ridge side molded part (4)
The folded portion (9) including the end portion of the elastic support portion (9) is inserted along the introduction surface of the elastic support portion (12) extending diagonally forward and upward, and is engaged and held by the abutment. In other words, the operation for engaging and connecting is simply to cover the molded part on the front ridge side (4) with the molded part on the next eave side (3) and engage the hooks. By connecting and fitting, the following actions and effects can be obtained.

That is, in this engaged and connected state, the sacrificial plate member (21)

Even if water floods into the first decompression space (25), there is a stepped section (lO) upright from the face plate section (2), so the first Coupled with the existence of the decompression space part (27) in No. 2, the same level is
Furthermore, with this configuration, there is no risk of flooding beyond this point.

The height of the front end edge (5) and, by extension, the height of the entire connection structure can be set low.9 For example, with sufficient margin, it is possible to set the protrusion height above the face plate to about 10II+1. As a result, the overall appearance can be summarized into an extremely clean shape.

〔Effect of the invention〕

As described in detail above, according to the present invention, a face plate part is formed in the longitudinal center of a long metal steel plate, and molded parts on each of the nine eave sides are formed on both sides of this face plate part, and on the front eave side. In a horizontal roofing plate in which a molded part is engaged with a molded part on the side ridge side of the next stage to form a horizontal roof, a relatively thin long metal sheet with high flexibility and elasticity is used as the material, On the side of the eave side molding part, one side of the face plate part is bent downward to form a front edge, the lower edge thereof is bent inward and rearward to form a contact pressure piece, and the rear end is raised to form a rising part. Furthermore, the holding portion is bent and extended toward the inner rear, and a folded portion is formed at the extended end of the holding portion, and
Raise the other side of the face plate on the side of the molded part on the ridge side to create a stepped section.
An engaging and holding part whose upper end edge is bent outward and rearward and folded back inward and upward to engage and hold the folded part including the end of the holding part.

An elastic support part that protrudes diagonally forward and upward and also serves as an introduction surface, and a support receptacle is formed at each end of the support receptacle, and in particular, the support receptacle is supported under the free elasticity that is open, and the front ridge side molding Since the rear eave side molded part can be engaged and connected to the front ridge side molded part, the first step is to cover the rear eave side molded part to the front ridge side molded part, that is, to connect the end of the holding part. Insertion and connection of the folded portions including the folded portions can be performed extremely easily and reliably with a single movement by the introduction surface of the elastic support portion, and furthermore, length dimensional errors of each portion in the engagement direction can be fully absorbed.
In addition, together with the good flexibility and elasticity of the materials,
Each engaging part has good mutual familiarity and can form a high-strength connection joint, and after joining, each part can maintain strong elastic contact regardless of the intervention of the sacrificial plate member or the hanger member. This maintains a good and strong sealing state and prevents rainwater, atom dust, etc. from entering from the outside in the first pressurized part, and rainwater etc. that enters due to capillary phenomenon etc. Directly from the face plate within the space.

Depending on the raised step, the presence of a second depressurized space can be added to prevent further water intrusion, and furthermore, the protruding height of the entire structure can be kept relatively low. Since it is configurable, resistance to wind and rain pressure is reduced and its effects are eliminated as much as possible.

Or it can be lowered as well as the appearance of the whole structure,
The protruding height of Aisho only creates a step line between the characters,
It has excellent features such as being able to be assembled into an extremely clean shape, and having an extremely simple and compact structure, easy molding, and no waste in cutting out material.
