Description

[Detailed Description of the Invention] The present invention relates to a roof panel constructed by bending metal plates.

Conventional roof panels include those shown in FIGS. 1 and 2.

This roof plate is constructed by bending a rectangular metal plate 1, and includes a protrusion 3 formed by bending one edge of a vertically connecting side edge 2 upward and outward, and the other edge of the vertically connecting side edge 2. A locking portion 4 is formed by bending the protruding portion 3 downward and inward.
The vertical connection is performed by alternately joining the locking portions 4 and 4.

Similarly, the lateral connecting portion 5 is formed by folding one edge upward and the other edge downward to form a folded edge, and the upper and lower folded edges of the left and right sides are joined to form a lateral connection. The roof is constructed by connecting vertically and horizontally, but roofs with this configuration require the use of hangers to secure the roofing material, which is troublesome and has the disadvantage that the fixation is not perfect. have.

Further, as shown in FIG. 3, a locking protrusion 3 with which a locking portion 4 of a predetermined length can be engaged with one side edge of the vertical connection side edge 2 is provided.
and a mounting part 6 extending from the locking protrusion 3, and when roofing, nails are driven into the mounting part 6 to fix it on the roof base plate, and the mutual connection is made using the lower roof board. The protruding part is engaged with the locking part of the upper roof board to perform a vertical connection.
In addition, Tsutsumi has proposed a method of joining the roof panels in the lateral direction by sequentially overlapping the upwardly bent portion of the side of each roof plate and the downwardly folded edge, and has already applied for a utility model registration. When overlapping and joining in the horizontal direction, the attachment parts of the left and right roofing materials overlap, increasing the wall thickness and making the folded joints poor in adhesion.The present invention further eliminates these drawbacks.
It is an object of the present invention to provide a roof board in which the operation of fixing the roofing material is extremely easy, the fixation is complete, and therefore the adhesion of the joints is extremely good.

The gist is that the front edge of the rectangular metal plate on the longitudinal connection side is bent downward to form a locking part, and the rear edge is bent upward in an S-shape to form the locking part. A locking protrusion that can be engaged with a locking protrusion, and a mounting part that extends rearward from the protrusion, and rectangular cut-out parts are provided at the left and right ends of the mounting part to extend toward the front edge. When the exposed folded portion is formed and one of the side edges of the lateral connecting side is bent upward to form the upper outer connecting portion, the other side edge is folded downward to form the lower inner connecting portion. be.

The present invention will be described in detail below with reference to the drawings.

FIG. 4 is a perspective view showing an embodiment of the present invention, and the same reference numerals in the figure indicate the same parts as in FIGS. 1, 2, and 3.

Its structure differs from conventional ones in the way the metal plates are bent and in the way cutouts are provided at the joints when connecting horizontally to prevent the joints from overlapping and increasing the wall thickness. .

That is, one is to improve the vertical connecting side edge 2, and the locking protrusion 3 and the locking part 4 that can hold the locking part 4 of a predetermined length on one side edge of the vertical connecting side edge 2 are improved. A mounting part 6 is formed extending from the locking protrusion 3, and when roofing, this mounting part 6 is fixed on the roof base board by driving nails, and the mutual connection is made using the protrusion of the lower roof board. The latching parts of the upper roof shingles are engaged with the upper roof shingles to form a vertical joint, and the side parts of each roof shingle are folded upward and downward, and the folded edges are overlapped in order to form a horizontal joint. By performing the joining and by providing cutout portions 9 at the left and right ends of the attachment portions of the vertical connection side edges, when the horizontal connection portions 5 are stacked one on top of the other in order, the attachment portions 6 overlap and the thickness of the portions increases. The binding is not sufficient and the operation is difficult.

This process is to prevent this.

Reference numeral 10 denotes a wood grain pattern formed protruding from the surface side of the metal plate 1, which is a three-dimensional pattern in the shape of wood grain.
A color different from the base color of 1, or a color similar to the base color but with a different tone is coated.

As mentioned above, this wood grain pattern may be formed by protrusions protruding from the surface of the metal plate 1, but conversely, it may also be formed by protrusions or grooves protruding from the back surface. It may be a print.

The case of covering a roof with the roof sheets constructed as described above will be further explained in detail with reference to FIGS. 5 to 7.

To connect roof panels 1 horizontally, connect the fixed roof panels 1
The upper outer connecting portion 5 is engaged with the lower inner connecting portion 5' of the roof panel 1 to be connected, and the roof panel 1 to be connected is moved in the direction of the arrow in FIG. 7 using a hammer or the like.

Then, the cut end surfaces 9a of the cut parts 9, 9 of the roof panels 1, 1
, 9a are brought into contact with each other.

At this time, the folded portion 3' extending toward the front edge of the fixed roof sheet 1 is located below the locking protrusion 3 of the roof sheet 1 to be connected, and the folded portion 3' of the roof sheet 1 to be connected is They are press-fitted below the locking protrusions 3 of the fixed roof panel 1, and water is completely prevented from entering from there.

Further, the side ends of the locking portions 4 of the fixed roof sheets 1 are surrounded by the side ends of the locking portions 4 of the roof sheets 1 to be connected.

In addition, when connecting vertically, when moving the roof panels 1 to be connected in the direction of the arrow as described above, the locking portion 4 is engaged with the locking protrusion 3 of the lower roof sheet 1, A nail 7 is driven into the attachment part 6 to fix it to the roof base plate 8.

In this case, the inclination angle and length of the protrusions of the locking portion 4 and the locking protrusion 3 need to be appropriate.

That is, by making the angle and length appropriate, at least one of both parts 3 and 4 is elastically deformed and engaged in the front and back directions of the roof board.

In this case, since the cutout portion 9 is provided, there is no overlapping of connections in the longitudinal and lateral directions, and it is possible to prevent the wall thickness from increasing.

Moreover, the cutout part 9 is a folded part 3' extending toward the front edge.
Since it is located one step higher than the locking part 4, even if rainwater blows in between the locking part 4 and the folded part 3' that engages inside, the intrusion will be prevented entirely by the bottom surface of the folded part 3'. It is blocked and flows down towards the leading edge.

Therefore, water does not intrude into the back side of the metal plate 1 from the cutout 9 located at a higher position, and there are various effects such as ensuring sufficient watertightness.
