Abstract

PURPOSE:To enhance the waterproofness by forming a waterproof joint from two members as a laying batten and a fit body, detaining the fit body with a detent provided in the center of the laying batten, and thereby accomplishing consolidation. CONSTITUTION:A laying batten B is constituted from a detent 4 for fitting of a fit body C, a runner part 2 formed by beding the lower edge of the laying joint part to the rear side, and a rain return part 3 formed by bending to the front side. The left and right side edges of this fit body C are folded back to accomplish the form of an encounter sack followed by fitting on a detent tung 8 installed at the two side edges of a decoration surface 7 of an exterior member D. The fit bodt C is detained with the detent 4 to achieve consolidation, and a waterproof joint A is formed. This enhances the waterproofness to a great extent.

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]

Conventionally, the joint structures when constructing exterior materials such as horizontal roofing materials and horizontal wall materials are: ■ A structure in which both edges of the exterior material are bent in a seam shape and joined to each other; A structure in which the side edges of the exterior material are sandwiched at the top and bottom by the board and the cover material, ■
It was 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 ■,
Particularly when applied to roofing materials, there is a risk that the cover material may be accidentally slid in the longitudinal direction of the exterior material in snowy regions, resulting in the joint portion being exposed to the outside.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention consists of a waterproof joint material consisting of two members, a sill plate and a fitting body, and the fitting body is a locking member having a pot-shaped cross section formed in the center of the sill plate. By being fixed to and integrated with the waterproof joint material, it is possible to prevent cuts, etc. from being made in the waterproof joint material, and also to bend the lower side of the seam part to allow water to flow down to the surface of the lower exterior material. The purpose of the present invention is to propose a waterproof joint material that has a ridge part, allows rainwater to quickly flow down, and is strong.

〔Example〕

Below, the waterproof joint material according to the present invention will be explained in detail. Figure 1 shows a typical example of the above-mentioned waterproof joint material A. For example, when constructing an exterior material as shown in Figure 4, it is located at the bottom of the vertical joint of the exterior material and has waterproof properties. At the same time, it connects the side edges of the exterior material. To explain further, waterproof joint material A is made up of siding board B and fitted body C.
As shown in FIG. 2(a), it is in contact with the back surface of the decorative surface 7 of the exterior material, and has a padding section 1 on which the fitting body C is attached, and a lower side of the padding section l. It is formed from a ridge part 2 bent to the back side, and a rain return part 3 formed by bending the upper side of the lining part 1 to the front side as necessary, and is an end view of the roller wire. (b) As shown in the figure, in the width direction, both side edges are folded back to the surface side, and the tip is folded back again to form a pot-like locking part 4, and an extension part 5 that extends both side edges of the locking part 4. and a tongue piece 6 formed by folding back the tip of the extension part 5 toward the surface side.

Note that this end face shape can be made substantially the same not only at the paving section 1 but also from the ridge section 2 to the rain return section 3. That is, the paving board B can be continuously formed by roll forming or the like.

As shown in Fig. 3, the fitting body C has a cross-sectional shape in which the left and right sides are folded back to form a meeting bag shape, and the engaging tongue pieces 8 provided on both side edges of the decorative surface 7 of the exterior material are fitted. , to be locked. To explain further, the fitted body C is integrally formed in the paving portion 1 of the paving board B by being locked at both ends by the locking portions 4, as shown in FIG. It is something that becomes.

Here, the dimensional relationship will be briefly explained. Now, as shown in FIGS. 2(a) and 2(b), in the padding board B, the length of the padding portion 1 is 42+, the opening width of the locking portion 4 is W+, and the locking portion 4 is
The width of the body is Wg, and the length of the fitted body C is j as shown in Figure 3.
If the ugs width is W3, lI≧12, W+ <Ws≦W
This is the relationship between 2.

Next, a construction example will be briefly explained. A waterproof joint material A as shown in FIG. 1, an exterior material D as shown in FIG. 4,
That is, it is assumed that an exterior material having engaging tongues 8 formed on both side edges of the decorative surface 7 by folding back toward the back side is used.

Therefore, one of the engaging tongues 8 of the exterior material is locked to the fitting body C of the waterproof joint material A so as to form a flap, and is disposed on the base. Next, the engaging tongue piece 8 of the adjacent exterior material is fitted and locked into the fitting body C of the waterproof joint material A. By doing this, the vertical joints will be connected as shown in FIG. In addition, in FIG. 5, the exterior material is shown by a dotted line.

In such vertical joints, rainwater that attempts to enter the interior is subjected to primary waterproofing by the fitting body C, secondary waterproofing by the locking parts 4,
It has a triple waterproof structure with tertiary waterproofing by the extension part 5 and the tongue piece 6, and the waterproofness is greatly improved. In addition, waterproof joint material A
Since it is fixed by the exterior material, the workability is good and there is no movement of the waterproof joint material A itself.

What has been described above is only one embodiment of the waterproof joint material A according to the present invention, and it may also be formed as shown in FIGS. 6(a) to (i) and FIGS. 7(a) to (b). can. That is, FIG. 6(a) shows a waterproof joint material A in which at least one protrusion 5a is provided on the extension part 5, and FIGS. Figures A and (d) show the mating body C at the lining part 1.
Waterproof joint material A made smaller. Figures (e) to (b) show waterproof joint material A obtained by modifying fitting body C. Figure (i) shows extension part 5.
This is a waterproof joint material A in which at least one strip of caulking material and backing material 9 is disposed on the bottom. Moreover, FIGS. 7(a) to 7(b) are end views shown in accordance with FIG. 5.

Of course, it is also possible to create waterproof joint material A that is a combination of these materials.

[Effects of the Invention] As described above, the waterproof joint material according to the present invention has good workability because there is no need to use a cover material, and the side edges of the exterior material can be fitted and locked to the waterproof joint material. Therefore, waterproofness is improved. Furthermore, since the waterproof joint 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 joint material itself. Furthermore, since the exterior material has a joint structure backed up by the waterproof joint material, deformation can be prevented. Furthermore, both the padding board and the fitting body can be roll-formed, resulting in good productivity. It has the following effects and characteristics.
