Abstract

PURPOSE:To beautify the joint sections for lateral roofing roof members and lateral boarding wall members, and enhance waterproof performance and productivity as well. CONSTITUTION:A splicing member is made up of a bed panel strip B at the center section of which a pot shaped locking section if formed, and of a guide section member C including a guide piece, and the guide section member C is so constituted that the guide piece is fitted in the right and left sections in such a way as to be tilted to the bottom surface of the locking section. When an exterior finish member is applied in such a way that an engaging slice is engaged with the guide piece, waterproof can be obtained because water rain is forced to flow down to the locking section. And this thereby allows the guide section member C to be fitted to the locking section with ease, and also allows productivity to be enhanced.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof joint material used for joints when roofs and walls are formed using exterior materials such as horizontal roofing materials or horizontal wall materials.

0002

[Prior Art] Conventionally, the joint structure when constructing exterior materials such as horizontal roofing materials and horizontal wall materials was: ■Both edges of the exterior material were bent in a seam shape and joined together. The structure was as follows: (1) a structure in which the side edges of the exterior material were sandwiched between upper and lower sides of the siding board and cover material, and (2) a structure in which the exterior materials were simply stacked on top of each other.

0003

[Problems 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. In addition, in case (2), especially when applied to roofing materials, there was a risk that the cover material would slide in the longitudinal direction of the exterior material when removing snow in snowy regions, and the joint portion would be exposed to the outside.

0004

[Means for Solving the Problems] In order to eliminate such drawbacks, the present invention consists of a waterproof joint material consisting of a sill board and a guide member, and a urn-shaped cross section provided approximately in the center of the sill board. By fitting and integrating the guide members into the locking part one on each side so as to be inclined with respect to the bottom of the locking part, cuts etc. are prevented from being made in the waterproof joint material. This project proposes a waterproof joint material that has the lower side of the eye part bent and has a ridge to allow water to flow down to the surface of the lower exterior material, which allows rainwater to flow down quickly, and which is also strong. be.

[0005]

[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 the exterior material D shown in Figure 4 is constructed, it is located at the lower part of the vertical joint of the exterior material D and provides waterproofness. , which connects the side edges of the exterior material D.

[0006] To explain further, the waterproof joint material A is made by integrating a slat plate B as shown in FIG. 2(a) and a guide member C as shown in FIG. 3. In other words, paving board B
As shown in FIG. 5, there is a padding section 1 that comes into contact with the back surface of the decorative surface 9 of the exterior material D and to which the guide member C is attached, and a fringed section 2 in which the lower side of the padding section 1 is bent toward the back side; It is formed from a rain return part 3 formed by bending the upper side of the paving part 1 toward the surface side as necessary, and is an end view of the roller line (
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 the tip of the extension part 5 back toward the surface side. Note that this end face shape is
In addition, it is possible to make the length from the ridge part 2 to the rain return part 3 substantially the same. That is, the paving board B can be continuously formed by roll forming or the like.

As shown in FIG. 3, the guide member C consists of at least a guide piece 7, and if necessary, one end of the guide piece 7 is bent to have an auxiliary fitting piece 8. As shown in FIG. 5, which is an end view taken along line A--A in FIG. It is integrated so as to be inclined with respect to the portion 4a, and engages and locks the engaging tongues 10 provided on both side edges of the decorative surface 9 of the exterior material D during construction. Note that the guide member C is integrally fitted to the left and right sides of the pot-shaped locking portion 4, respectively, and therefore manufacturing is facilitated.

[0008] Here, the dimensional relationship will be briefly explained. Now, as shown in FIGS. 2(a) and 2(b), in the padding plate B, the length of the padding portion 1 is l1, and the opening width of the locking portion 4 is W1.
, the width of the locking part 4 is W2, the length of the guide member C is l2 as shown in FIG. 3, the width of the auxiliary fitting piece 8 is W3, and the width of the guide piece 7 is W4, then l1 ≧l2, W1
>W3, 1/2W2 >W3, W4 ≦1/2W2
There is a relationship between

Next, a construction example will be briefly explained. Now, a waterproof joint material A as shown in FIG. 1 and an exterior material D as shown in FIG. Assume that it is used. Therefore, one of the engaging tongues 10 of the exterior material D is locked to the guide member C of the waterproof joint material A so as to form a flap, and is disposed on the base. Next, the engaging tongue piece 10 of the adjacent exterior material D is fitted and locked into the guide member C of the waterproof joint material A. By doing this, the vertical joints will be connected as shown in FIG. 5. In addition, in FIG. 5, the exterior material D is shown by a dotted line. In such a vertical joint part, rainwater that is about to enter the inside is returned to the locking part 4 by the guide member C, flows down, and is discharged to the lower stage. Also,
Since the waterproof joint material A is fixed by the exterior material D, workability is good and the waterproof joint material A itself does not move.

What has been described above is only one embodiment of the waterproof joint material A according to the present invention, and FIGS.
) to (c), Fig. 8(a) to (c), Fig. 9(a) to (e)
It can also be formed as shown in FIG. In other words, (
a) is a waterproof joint material A in which the extension part 5 is provided with at least one protrusion 5a; (b) and (c) are waterproof joint material A in which the rain return part 3 and the ridge part 2 are deformed; a) is a waterproof joint material A in which the guide member C is smaller than the lining part 1, FIGS. 7(b) and (c)
, FIGS. 8(a) and 8(b) show waterproof joint material A obtained by modifying guide member C, respectively, and FIG. 8(c) shows waterproof joint material A in which at least one strip of caulking material and packing material 11 is disposed on extension portion 5.
It is. Moreover, FIGS. 9(a) to 9(e) are end views shown according to FIG. 5. In particular, FIG. 9(a) shows a waterproof joint material A in which the guide member C is only the guide piece 7.

[0011]

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. In addition, since the waterproof joint material is fixed by the exterior material, there is no water leakage due to nailing, etc.
Moreover, 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. Moreover, each of the padding board and the guide member can be roll-formed, resulting in good productivity. Further, since the structure is such that the guide members are fitted to the left and right sides of the locking portion, it is easy to attach the guide members to the paving board, and productivity is improved. It has the following effects and characteristics.
