Description

[Detailed explanation of the invention] (a) Technical field of the invention This invention relates to flat roofing materials used as roof exterior materials for buildings, and more specifically, aims to stabilize the connection structure of the roofing materials. Regarding ivy roofing materials.

(b) Background of the invention Conventionally, in the joint structure of this type of roofing material,
By overlapping and engaging the ends of mutually adjacent face plates vertically and horizontally, these face plates are connected in a continuous plane in the plane direction (for example, Japanese Utility Model Application No. 57-15838).

However, in general, with such an engagement means that only pulls in the plane direction, the strength of the entire connected face plate is weak and insufficient, so some kind of reinforcing member such as a detachment prevention piece is attached to the engagement part etc. As a result, the number of component parts has increased, and the sealing performance of the engaging portion has been insufficient.

(c) Purpose of the invention Therefore, the purpose of this invention is to provide a roofing material that can stably connect mutual face plates without requiring reinforcing members.

(d) Summary of the invention This invention provides stable support that provides uniform and stable support over the entire face plates to be connected by providing a biasing protrusion that utilizes the elastic force of the face plate at the engaging portion of the face plate. It is characterized by being a roofing material that retains its structure.

(e) Effects of the invention According to this invention, after the face plates are connected, the lower biasing protrusions formed on the lower edge engaging parts of the face plates can hold the mutual face plate engaging parts connected in the vertical direction in a predetermined position. Since the support force is applied to the support biasing pressure of Since it is provided with a protruding structure, its biasing support force is transmitted to the entire long face plate, resulting in a stable connection. Moreover, due to the biasing action of the biasing protrusions, a tight seal is always obtained between the face plates, and the infiltration of rain and the like is reliably prevented.

In addition, the upper biasing protrusion formed on the connecting member reliably biases and supports the portions that should support both side edge engaging portions of the left and right face plates, so that the mutual face plates that are connected laterally are engaged. to stably bias and support the parts.

In this way, the biasing protrusion provides sufficient bonding strength to the face plate, eliminating the need for additional reinforcing members such as detachment prevention pieces, as is currently the case, and making it possible to reliably reduce the number of component parts. Work effort can be reduced and costs can be reduced.

Furthermore, since the connection has a biasing support structure, it also has excellent vibration resistance against external vibrations and the like.

(f) Embodiment of the invention An embodiment of the invention will be described below in detail based on the drawings.

The drawing shows a roofing material used for the outer surface of a building's roof, etc. As shown in FIG. It is arranged and connected on a plane, and is composed of a face plate 2, a fixture 3, a connecting member 4, and a waste plate 5.

The above-mentioned face plate 2 is formed into a rectangular plate shape by, for example, a thin steel plate, and has a rising portion bent inwardly at a right angle on its upper edge, and the bent edge is further bent downward. The lower edge is provided with a notch 7 in the center, and the bent edge thereof is bent downward and inward for upper edge engagement, It has a lower edge engaging portion 9 provided with a lower biasing protrusion 8 formed by bending the inwardly bent edge further downward at an angle,
The left and right side edge pieces have side edge engaging portions 10, 10 with rising portions facing each other and bent inward.

In addition, at the upper edges of the side edge engaging parts 10, 10, between this upper surface and the upper edge engaging part 6 facing above,
That is, a slight gap is formed between the overlapping surfaces at the corners, and an upper biasing protrusion of a connecting member, which will be described later, is engaged with this gap 11 to maintain bias.
12 is a screw corresponding to the connecting member, and 13 is a screw hole.

FIG. 3 shows the vertical connection between these face plates 2, 2, and the upper edge engaging part 6 of the lower face plate 2 is connected to the lower edge engaging part 9 of the upper face plate from the outside in a U-shape. They are connected in the vertical direction by engaging each other as if covering each other.

As shown in FIG. 4, the aforementioned fixture 3 fixes the face plate 2 on the elongated face plate fixing member 14 disposed vertically on the lower surface of the face plate 2 via the fixture 3. The screws 15 are attached to the lower side on the face plate fixing member 14 while the upper side of the two step-shaped upper and lower steps is engaged with the upper edge engaging portion 6 of the face plate 2.
Stop and fix.

As shown in FIG. 5, the above-mentioned connecting member 4 is
The face plate 2 has a length equivalent to the vertical direction of the face plate 2...
While the side edge engaging portions 10 of ... are abutted left and right and the side edge engaging portions 10, 10 are externally engaged in the vertical direction, the above-mentioned face plate 2 is It has a U-shaped cross section that is partially inserted into the notch 7, and an upper biasing protrusion 16 for biasing support is provided on the upper edge of the U-shaped open surface facing downward to project upwardly. The lower edge is provided with a locking piece 17 for engagement with the lower edge, which is formed by further bending the downward bent edge inward.

The above-mentioned upper biasing protrusion 16 is inserted into the gap 11 of the above-mentioned face plate 2 when connecting the face plates in the lateral direction, and is fixed with screws 12 in the inserted state.
18 is the screw hole.

Further, the locking piece 17 covers and holds both lower edge engaging portions 9, 9 which are in mutual contact with each other when the left and right face plates 2, 2 are connected, so as to wrap them in a U-shape from the outside.

The above-mentioned waste plate 5 has a flat plate shape with a length equivalent to that of the face plate 2 in the vertical direction, and an inner part is provided on the upper edge of the flat plate to stably hold the entire upper edge of the above-mentioned connecting member 4. A U-shaped fitting part 19 bent in the direction protrudes from the upper surface, and several protruding grooves 20 for guiding rainwater vertically are protruded in parallel from the upper surface in the vertical direction.
This increases the connection strength between the lateral face plate connections and also improves the sealing performance. In the figure, 21 is a sealing material.

The roofing material constructed in this way is first
Attach the face plate 2 onto the face plate fixing member 14 through the screws 15.
In addition to fastening, the vertical connection is performed by providing the upper edge engaging portions 6 and 9 of the face plates 2 and 2 to engage with each other and pull them together in the vertical direction. .

In addition, for lateral connection, the side edge engaging portions 10, 10 of the left and right face plates 2, 2 are integrally fitted and supported on the left and right by the connecting member 4, and the waste plate 5 and the sealing material 21 are attached. The lateral connection is made by fixing with screws 12.
