Abstract

PURPOSE:To improve waterproof performance by folding back a batten part in its right and left sides forming a hook part forming a winding piece winding around a run part in a lower side of the batten part. CONSTITUTION:A batten part 1 is largely folded back in its right and left sides forming a hook bag shape and a hook part 2 engaged with a runner-shaped engaging tongue piece in the end part of a facing material. The batten part is flexed in its lower side, forming a run part 3 for water to flow down in a facing material surface in a lower step. Next, a winding piece 4, winding around the run part 3 so as to embrace it and allowing rainwater, infiltrating in the batten part 1 and the hook part 2, to promptly flow down, is formed halfway a lower side of the hook part 2. In this way, waterproof performance can be improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a waterproofing method for use in joints when roofs and walls are formed using exterior materials such as horizontal roofing materials or horizontal wall materials. This relates to joint materials.

[Conventional technology l Conventionally, when constructing exterior materials such as horizontal roofing materials and horizontal wall materials, the joint structure was ■Both edges of the exterior material were bent in a seam shape, and jointed with each other. Structure, ■Structure in which the side edges of the exterior material are sandwiched at the top and bottom by the paving board and cover material,■
It had a structure in which exterior materials were simply layered on top of each other.

[Problem to be solved by the invention]

However, in these structures, (1) is inferior in waterproofness, and (2) and (2) have disadvantages in that stacking of exterior materials results in irregular steps, resulting in a deterioration in design. Also, in ■
In particular, when applied to roofing materials, there is a risk that the cover material may slide in the longitudinal direction of the exterior material during a misunderstanding in a snowy region, resulting in the joint portion being exposed to the outside.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention has the left and right sides of the padding portion folded back to form a meeting bag shape, and has an engaging portion that engages with the flap-like engaging tongue at the end of the exterior material. In addition, the lower side of the bedding part is bent, and has a ridge part for letting water flow down to the surface of the lower exterior material, and is wound so as to hold the ridge part in the middle of the lower edge of the hooking part. The present invention proposes a waterproof joint material that is strong and allows rainwater that has entered the paving and hooking parts to quickly flow down.

〔Example〕

Below, the waterproof joint material according to the present invention will be explained in detail. Figure 1 shows typical examples of the above-mentioned waterproof joint materials, which are made by bending and forming metallic materials such as colored steel plates, stainless steel plates, copper plates, aluminum plates, clad steel plates, sandwiched steel plates, and heat-insulating steel plates. It is something. In other words, as shown in FIG. 2, which is an end view of the E line, the waterproof joint material has a cross-sectional shape in which the left and right edges of the padding portion 1 are largely folded back, and the hooking portion 2 meets at the center of the dowel. It is molded. This engaging portion 2 locks the retaining tongue piece 5 of the exterior material A as shown in FIG. In addition to being a part that serves as a backup for the exterior material A at the joints, it also serves as a backup for the exterior material A at the joints. In addition, in FIG. 2, the exterior material A is shown by a dotted line. In addition, since the engaging portion 2 is formed by folding back both side edges of the paving portion 1, it also functions to allow rainwater to flow onto the lower exterior material A without being spread laterally. Further, the lower side of the padding portion l has a ridge portion 3 bent in the opposite direction to the engaging portion 2, for example, into an L-shaped cross section, a U-shaped cross section, or the like. This ridge part 3 is placed on or engaged with the upper connecting part 6 to the lower cladding material, and serves as a guide to guide rainwater flowing down on the sill part 1 to the lower cladding material on the surface. It is something that fulfills a function.

Further, at the lower side of the hooking part 2, a winding piece 4 is formed so as to hold the arm part 3 at a part of the way.

That is, the winding piece 4 is formed in the area excluding the 1+ range from the side edge of the padding part l and the range of 1g from the tip of the hooking part 2, and the distance between the hooking part 2 and the padding part l is This is to keep it constant. Further, since the winding piece 4 is provided midway along the lower side of the engaging part 2, even if rainwater infiltrates up to the side edge of the paving part 1, it can be discharged without accumulating. In addition,
Reference numeral 7 denotes a protruding strip, and if necessary, at least one strip is provided in the paving section l from the upper side to the lower side, which prevents the diffusion of rainwater and also serves as a retaining tongue 5 and a hooking section to the exterior material. The degree of contact with 2 is increased to further strengthen waterproofness. Further, it is preferable that the boundary between the padding portion 1 and the engaging portion 2 be shaped like a pipe as shown in FIG. This is to further promote the flow of rainwater and to further strengthen the backup of the exterior material A. Furthermore, by making the hooking portion 2 also have a mountain-shaped cross section, the waterproof property and the backup function of the exterior material A can be strengthened.

What has been described above is only one embodiment of the waterproof paving material according to the present invention, and it can also be formed as shown in FIGS. 4(a) to 4(d). That is, (a) the waterproof lining material with the rising part 8 formed on the upper side, (b) the waterproof lining material with the rising part 8 formed in a U-shape or a U-shape, (C), (d) ) The figure shows a waterproof paving material in which a rising portion 8 is formed almost in the same way as the upper connection portion to the exterior material. Further, as shown by the dashed line in FIG. 4(a), it is also possible to implant a caulking material or a backing material 9 on the surface of the engaging portion 2 to strengthen the sealing property.

〔Effect of the invention〕

As described above, the waterproof paving material according to the present invention has good workability because it does not require the use of a cover material, and has good waterproofness because the side edges of the exterior material are locked to the waterproof paving material. will improve. In addition, since the waterproof paving material is fixed by the exterior material, there is no leakage of water due to driving of nails, etc., and there is no movement of the waterproof paving material itself. Furthermore, since the exterior material has a joint structure backed up by waterproof paving material, deformation can be prevented. It has the following effects and characteristics.
