Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal roofing material which is laid on the underside of a roof or a metal exterior plate material which is laid on a wall surface of a building.

[0002]

2. Description of the Related Art A horizontal roofing metal roofing material provided with an adhesive material on the back surface is already known. As shown in FIG. 16, this type of metal roofing material has a goby portion on the upper and lower ends of a metal thin steel plate such as a tin, tinplate, and thin steel plate (the upper side may be referred to as above the water, and the lower side may be referred to as below the water). a and b are formed to be bent, and the adhesive material e is wound up to the back surface and the surface of one or both end portions. When constructing such a metal roofing material, as shown in FIG. 17, a primer is applied on the foundation of the roof to increase the adhesiveness, and a waterproof sheet provided with an adhesive layer such as non-sulfided butyl rubber on the back surface is used. A base f of the roof is formed by coating or the like, and the first metal roofing material P1 from the lowermost end of the base f thus formed is adhered by the adhesive e on the back surface. Then, the back surface of the left end portion of the other metal roofing material P2 is superimposed on the surface of the adhesive material e at the right end portion of the metal roofing material P1, and adhered via the adhesive material e provided on the P1. At this time, in the manner shown in FIG. 18, the upper and lower goby portions a and b on the other metal roofing material P2 overlap with the upper and lower goby portions a and b on the first metal roofing material P1. Then, in the same manner, the back surface of the left end portion of the next metal roofing material P3 is superimposed on the surface of the adhesive material e at the right end portion of the metal roofing material P2 already adhered to the base f of the roof. While the metal roofing materials P1, P2,... Are sequentially adhered to the base f by the adhesive material e provided on the back surface thereof,
Connect in the horizontal direction.

On the other hand, as shown in FIG. 17, the vertical connection of the metal roofing material is performed so as to straddle the upper end goose portions a, a of the metal roofing materials P1, P2 already connected in the horizontal direction. Then, after approximately the center of the lower end gob portion b of another metal roofing material P10 is located, the lower end gore portion b is connected to the metal roofing material P
1. Locking from above P2, another metal roofing material P
Adhesive material e on the back surface of No. 10 is adhered to base f.

A series of operations are repeated in the same procedure as described above, and the upper and lower metal roofing materials P1, P2 and P1
The metal roofing material is sequentially connected to the surface of the base f of the roof in a zigzag manner by hitting and caulking the upper and lower ends gob portions a and b with a gavel or the like. Here, the term “caulking” may be referred to as “goby tightening” or “inclination”, but is used in the present specification as synonymous with these. Since the adhesive material e of the metal roofing material is coated with release paper in advance, the adhesive material e is peeled off at the time of construction and used. In the above description, the example of the right roofing construction is shown. However, in the left roofing construction, the right end of another metal roofing material is superimposed on the left end of the metal roofing material, and sequentially joined and connected. Furthermore, there is also a construction method in which the base f of the roof is formed without covering the waterproof sheet provided with the adhesive layer. In such a construction method, the metal roofing material is directly attached to the primer surface.

[0005]

However, the above-mentioned conventional roofing metal roofing material has the following problems. 1) Since the pressure-sensitive adhesive material used when polymerizing and connecting metal roofing materials has a strong adhesive force, once bonded, the position cannot be adjusted. In addition, when metal roofing materials are overlapped and connected, the upper and lower ends of the metal roofing material will be in the way, so the next metal roofing material must be properly aligned and fitted from the side of the metal roofing material already attached. Therefore, it is difficult to perform the construction without skilled workers. 2) Further, if the metal roofing materials are stuck in a state where they are misaligned in the lateral direction, even a slight misalignment causes the misalignment to become an overlapping error and meander. When the displacement occurs, the displacement is corrected by hitting it with a gavel or the like.
As shown in (1), a curved distortion may occur at the joint end of the metal roofing material P. If a gap d is generated at that time, rainwater or the like flows in from the gap d and causes a rain leak. Rainwater also weakens the adhesion between the two. 3) Further, as shown in the longitudinal end view of FIG. 20, the metal roofing materials P are connected to each other by overlapping their joints, so that a step g is generated at the joints and the metal roofing materials P are connected to each other. The surface cannot be flush. For this reason, the appearance and appearance of the finished product were deteriorated. 4) Further, even if the metal roofing materials P can be connected to each other accurately, as shown in the plan view of FIG. The deviation eventually resulted in an error at both ends of the roof.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a roofing metal roofing material according to the present invention; [First Embodiment] FIG. 1 is a perspective view showing an embodiment of a horizontal roofing metal roofing material according to the present invention, and FIG. 2 is a partially enlarged longitudinal sectional view thereof. The feature of this embodiment lies in that the joint portion is formed integrally with the metal roofing material main body. Hereinafter, in these figures, reference numeral 1 indicates a metal roofing material main body formed in a rectangular shape in a plan view using a base material such as a galvanized iron, a tin plate, and a painted thin steel plate. The metal roofing material main body 1 is formed with an upper goby portion 2 having an upper end bent at an acute angle toward the surface and a lower goby portion 3 having a lower end bent at an acute angle toward the back surface. The upper and lower goby portions 2 and 3 constitute a connecting portion when connecting the metal roofing material main body 1 in a staggered manner, and function as drainers at the end faces. The joint portion 4 has a structure in which an extension piece 5 extending from the right end of the metal roofing material main body 1 is double-folded downward to have a step, that is, a step-down structure. The connecting goby piece 6 erected at a sufficiently large angle is bent at the upper end thereof.
Adhesive materials 81 and 82 made of the same adhesive rubber as the back surface of the metal roofing material main body 1 are provided on the front surface 41 of the joint portion 4 and both end edges of the connecting goby piece 6. 8
The two surfaces are covered with release paper (not shown) that is peeled off during use. In addition, the water cutting piece 42 bent in the same direction as the lower goby part is also formed at the lower end of the joint part 4, and when the metal roofing material main bodies 1 are joined together, a gap is generated in the joint part. Although it is possible to prevent infiltration of rainwater, the structure of the joint part 4 of the present invention is not always necessary. FIG. 3 is a perspective view showing another embodiment of the horizontal roofing metal roofing material according to the present invention, and FIG. 4 is a partially enlarged longitudinal sectional view thereof. This embodiment also has the same feature that the joint is formed integrally with the metal roofing material main body, but is characterized by the connecting goby piece 6 provided at the upper end of the joint. That is, similarly to the above-described embodiment, the joint portion 4 has a structure in which the extension piece 5 extending from the right end of the metal roofing material main body 1 is double-folded downward to have a step, that is, a step-down formation. A common feature is that the connecting goby piece 6 erected at an angle sufficiently larger than the upper gob portion 2 is bent at the upper end thereof. However, the connecting goby piece 6 of this embodiment is characterized in that it is formed so as to be continuous with the upper goby portion 2.

In order to form the connecting goby piece 6 as in this embodiment, for example, after forming the extending piece 5,
And the connecting goby piece 6 is also bent together with the bending process, and thereafter, only the portion corresponding to the connecting goby piece 6 is made to stand up more than the upper goby portion 2. Since the connecting goby piece 6 is formed so as to be continuous with the upper goby portion 2, no gap is formed between the connecting goby piece 6 and the upper goby portion 2. Therefore, in the above-described embodiment, two adhesives 82 are provided at both end portions of the connecting goby piece 6, but in the connecting goby piece 6 of the present embodiment, only the edge is provided as shown in the drawing. If the adhesive 82 is provided, infiltration of rainwater can be prevented. Further, in the case of the connecting goby piece 6 as in the present embodiment, it is possible to easily form a horizontal roofing metal roofing material using a single rectangular metal plate without prior processing. In addition, almost all of the back surface of the metal roofing material body 1 is formed with an adhesive material 9 to which an adhesive rubber having a waterproof property or a waterproof property is adhered. A release paper (not shown) to be peeled off is covered.

The adhesive material 81 provided on the surface 41 of the joint portion 4 has a sufficient adhesive strength with the adhesive material 9 provided on the back surface of another metal roofing material body to be superposed and connected to the surface 41. Although not necessarily required in this case, the provision of the adhesive 81 not only enhances the initial adhesive strength to facilitate the construction, but also more effectively prevents rainwater intrusion from the connecting portion connected by polymerization. FIGS. 5A and 5B show various modifications of the joint portion 4. FIG. 5A shows the joint portion 4 formed integrally with the metal roofing material main body 1.
(B) and (c) show that the joint part 4 is constituted by a plate member 7 formed separately from the metal roofing material main body 1. In these drawings, the adhesive 81 provided on the front surface 41 of the joint portion 4 corresponds to the adhesive 9 formed on the back surface of the metal roofing material main body 1.
Is continuous from the back surface of the joint portion 4 to the right edge of the front surface 41. In such a case, since the right edge of the metal roofing material main body 1 is coated with the adhesive rubber, the metal roofing material main body 1 can be protected without performing the edge processing. In the horizontal roofing metal roofing material of the present invention, the joint 4
It is desirable that the connecting goby piece 6 be erected at an angle such that it does not hinder the insertion of the side end of another metal roofing material. Therefore, the left end of the other metal roofing material can be easily polymerized, and if the connecting goby piece 6 is caulked after the polymerization connection, it can be easily and accurately connected without causing a positional shift. In the illustrated example, the adhesive 82 provided on the connecting goby piece 6 has one or two layers formed on both side edges of the inner surface, but may be provided on the entire inner surface of the connecting goby piece 6. Good.

The adhesive material 81 is formed by polymerizing the other side end of another metal roofing material on the joint portion 4 of the metal roofing material main body 1 formed with a step, and then caulking the connecting goby piece 6. After fixation, there is a particularly beneficial effect for eliminating rainwater intrusion from the gap and ensuring a waterproof effect. Also, as shown in FIG. 6 in addition to the examples of FIGS. 1 and 3, the joint portion 4 formed on the metal roofing material main body 1 is formed such that the right end of the metal roofing material main body 1 is formed downward at right angles in an L-shape. It may be bent to form a step, and in any case, the surface 41 has a structure having a step m with respect to the metal roofing material main body 1. In the state where the other side end of the other metal roofing material is overlapped and joined, it is possible to form the step m in such a size that both sides are flush with each other. Particularly desirable in terms of improving.

FIGS. 7 and 8 show various embodiments of the connecting goby piece 6. FIG. FIG. 7 shows a configuration in which the connecting goby piece 6 is formed so as to protrude further outward than the upper goby portion 2 of the metal roofing material main body 1, and the connecting goby piece 6 is fixed by caulking from the outside of the upper goby portion 2. It is structured to be. FIG.
The connection gob piece 6 is formed by cutting out a part of the right side of the upper gob portion 2 and projecting further outward from the upper edge of the metal roofing material main body 1. Any of the embodiments can be adopted for the metal roofing material of the present invention. [Second Embodiment] FIG. 9 is a perspective view showing another embodiment of a horizontal roofing metal roofing material according to the present invention, and FIG. 10 is an enlarged vertical sectional view of a main part thereof. This embodiment is characterized in that a stepped portion is formed by joining a separately formed plate material 7 to the back surface of the metal roofing material main body 1 as the joint portion 4 having the connecting goby piece 6 formed thereon. The plate member 7 formed as the joint portion 4 is obtained by, for example, cutting a single thin metal steel strip having the upper side bent and formed of the same material as the metal roof body 1 at appropriate intervals, as shown in FIG. Can be formed as shown in FIG. Note that the water piece 42 may be formed by appropriately bending the lower end to the back side.

In order to form the joint portion 4, the plate member 7 formed as described above is attached to at least one side end of the metal roofing material main body 1, in the illustrated example, an adhesive or the like on the back surface of the right end. The joining may be performed by welding or other methods. In this case, the joining may be performed by positioning the connecting goby piece 9 so as to protrude further outside the upper goby portion 2 of the metal roofing material main body 1. By joining the plate material 7 from the back surface in this manner,
A step m is formed between the surface of the metal roofing material main body 1 and the surface of the plate material 7, and a step is formed.

As described above, if the plate 7 as the joint portion 4 is formed separately from the roof plate body 1, the plate 7 having the connection goby pieces 9 formed thereon is simply joined to the conventional horizontal roofing metal roof. Thus, the roofing metal roofing material according to the present invention can be easily manufactured. Therefore, such separately formed plate material 7
