Description

[Detailed Description of the Invention] The present invention relates to a face plate that is a constituent unit of a surface structure such as a roof or a wall.

This type of face plate generally has an inwardly bent locking edge 20 at the front end of a plate 10 and an outwardly bent locking edge 30 at its rear end, as shown in FIG. The retaining edge 20 has a downward vertical portion 21 and a folded portion 22.
The outwardly bent locking edge 30 has a diagonally upwardly folded portion 31 and a hanging portion 32 formed by bending the tip of the folded portion 31 downward.

In the surface structure, while fixing the face plate having the above structure with the claws or hangers of the support member, the outward bent locking edge 30 of the lower face plate is fixed to the inward bent locking edge 20 of the upper face plate.
It is formed continuously by meshing with each other. However, this conventional surface structure using a face plate does not have sufficient strength for practical use against simple lateral tension or vertical tension applied to the meshing portion between the inwardly bent locking edge 20 and the outwardly bent locking edge 30. However, if the lower surface of the folded part 22 of the inwardly bent locking edge 20 is blown up by a rainstorm or the like, and strong wind blows into the gap between the folded part 22 and the face plate below it, unexpected effects may occur. It has been found that the inwardly bent locking edge 20 is brittle and may curl up and become disengaged from the outwardly bent locking edge 30.

The present invention was made with the aim of preventing this curling-up phenomenon of the inwardly bent locking edge. A bent locking edge is provided, and an outwardly bent locking edge having a diagonally upward folded portion and a hanging portion from the folded portion is provided at the rear end, and the inner bent locking edge of the vertically adjacent plate material In the face plate that engages and connects with the outwardly bent locking edge, the folded portion of the inwardly bent locking edge is a low, upwardly extending portion provided halfway in the width direction of the folded portion over the entire length of the plate material. It has a rising part and an inclined part facing rearward from the upper end of the rising part, and when the inward bending locking edge and the outward bending locking edge are engaged, the inward bending locking part is attached to the rising part. The hanging part of the outwardly bent locking edge that engages with the edge faces, and a space is formed on the back side of the rising part surrounded by the back surface of the rising part, the lower surface of the inclined part, and the rear upper surface of the plate material. It is characterized by

The invention will now be described with reference to illustrated embodiments.
The face plate according to the present invention has a plate material 10 as shown in FIG.
This embodiment is characterized by an inwardly bent locking edge 20 at the front end, and an outwardly bent locking edge 30 in this embodiment has almost the same structure as that of the conventional product shown in FIG. That is, the inwardly bent locking edge 20 has a downward vertical portion 21 and a folded portion 22.
This folded part 22 has a low rising part 23 that extends upward and is provided halfway in the width direction of the folded part 22 over the entire length of the plate material 10, and a low rising part 23 that extends upward from the upper end of the rising part 23. Inclined portion 22' toward
It has The rising portion 23 is located at a position where the hanging portion 32 of the outwardly bent locking edge 30 that engages with the inwardly bent locking edge 20 faces.
The inwardly bent locking edge 20 is formed over the entire length thereof at a position where it abuts and engages with the locking edge 20. and slope part 2
2' is slightly inclined downwardly from the upper end of the rising part 23 and extends rearward, so that the lower end of the inclined part 22' can come into contact with the rear upper surface of the plate member 10 adjacent to the lower side.
In the illustrated embodiment, at the lower end of the inclined portion 22',
A folded end portion 24 is formed by folding the lower end of the inclined portion 22' upward.

The face plate configured as described above can form a face structure by engaging the outward bent locking edge 30 of the lower face plate with the inward bent locking edge 20 of the upper face plate, as in the conventional case. can. When the inwardly bent locking edge 20 lifts due to strong wind or other external force,
As mentioned above, the rising portion 23 provided on the folded portion 22
Since the entire length of the inwardly bent locking edge 20 abuts and engages with the hanging portion 32 of the outwardly bent locking edge 30 meshing with the inwardly bent locking edge 20, lifting of the inwardly bent locking edge 20 is reliably prevented. Therefore, it is possible to avoid a situation where the inwardly bent locking edge 20 and the outwardly bent locking edge 30 become disengaged.

Further, on the back side of the rising portion 23, the rising portion 2
3, the lower surface of the inclined part 22', and the rear upper surface of the plate material 10 adjacent to the lower side form a space 25. Rainwater that tries to infiltrate through the gaps due to capillary action enters this space 2.
5 and cannot penetrate further. Since this space 25 also serves to prevent pressure from increasing on the lower surface of the folded portion 22 due to strong winds, it has the effect of preventing the phenomenon of the inwardly bent locking edge 20 rising itself. Note that the folded end portion treatment 2 of the folded portion 22
4 is effective in eliminating the risk of damaging the surface treatment of the base end portion of the folded portion 31 of the outwardly bent locking edge 30 and preventing electrolytic corrosion from occurring.

Note that the obliquely upwardly folded portion 31 of the outwardly bent locking edge 30 may have any shape as long as it has a hanging portion 32 connected to its upper end. For example, as shown in FIG. 3, one or more chevron portions 33 may be provided to increase the elasticity of the folded portion 31 itself.

In summary, the face plate according to the present invention has a low upwardly rising part provided on the entire length of the folded part of the inwardly bent locking edge, and a hanging part of the outwardly bent locking edge that engages with the inwardly bent locking edge, which extends over the entire length. By the abutting engagement between the two, it is possible to prevent the inwardly bent locking edge from lifting up or curling up. In addition, even if the inwardly bent locking edge lifts up slightly during strong winds, in this invention, the rising part and the hanging part abut and engage with the hanging part over the entire length of the plate, so The lifting force of the inwardly bent locking edge can be distributed in the longitudinal direction of the inwardly bent locking edge. It will not float any further, and the board will not roll up due to disengagement of both locking edges. Furthermore, in this invention, since a space is formed on the back side of the rising part, the intrusion of rainwater due to capillary phenomenon that occurs when the plates are in close contact with each other is blocked by the space, and rainwater does not flow beyond the space. No infiltration. Therefore, rainwater will not seep into the attic.
