[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a seal suitable for preventing water from stopping at joints of a hollow cement molding plate used for an outer wall of a building.
It relates to a backup material that significantly enhances the utility of the material.

[0002]

2. Description of the Related Art In recent years, a hollow cement molding plate 6 (Asrock Mace) as shown in FIG. 8 is often used for an outer wall of a building. The hollow cement molding plate 6 is usually made of a flat block material made of a ceramic material, and has, for example, a plurality of rectangular hollow holes 9 as shown in the figure. This hollow hole 9 opens to the cut section 10 side. The hollow cement molding plate 6 is formed by arranging the cut portions 10, 10 of a pair of adjacent hollow cement molding plates 6, 6 so as to face each other to form an outer wall. It is formed. Since the hollow cement molding plate 6 itself does not take any measures against water stoppage, a backup material 1a must be inserted into the joint and sealed as shown in FIG. 9 to prevent water stoppage at the joint.

[0003]

As shown in FIGS. 9 to 11, a string-shaped backup material 1a inserted into a joint is provided.
Indicates that a portion of the backup material 1a enters the hollow hole 9 in a portion having the hollow hole 9 and a portion without the hollow hole 9
The sealing member 12 is pushed into the gap between the first and second pins 10 and 10 to reduce the thickness. For this reason, there is a problem in that even when the seal between the hollow holes 9 is sufficient, the seal is insufficient at the portion without the hollow holes 9. That is, it is difficult to seal joints uniformly. In particular, the hollow cement molding plate 6 has a hollow hole 9
There is a problem that the sealing rate is insufficient due to a large percentage of tightening, and the prevention of water stoppage at the joint is incomplete. In addition, conventional
What is called a backup material is often rubber-based and soft
Easy to deform. Therefore, from the part that easily deforms
The drawback that rainwater often leaks in
There is.

[0004] The present invention solves the above-mentioned problems. In addition, the joint can be uniformly sealed, and the joint itself has a sealing property , prevents deformation of the seal portion, and prevents water from stopping at the joint. It is an object of the present invention to provide a backup material that can significantly improve the utility of a sealing material for a hollow molded plate that can reliably perform the above.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an adjoining cut section of a hollow molded plate which is formed on a cut section side and has a plurality of hollow holes arranged at appropriate intervals. Sealing backup material interposed between joints, which is hard enough to have some flexibility and is not easily deformed
Is composed of quality, made from those integrally formed a convex portion having a contour that fits in the thickness direction to protrude the hollow hole of the base portion and the base portion of a thickness commensurate with the joint, the protruding portion, It constitutes a back-up material for sealing a hollow molded plate disposed at the same interval as the hollow holes. The seal backup material is provided with a male locking tool at one end and a female locking tool at the other end. The length of the seal backup material. Still further, the backup material for sealing is most preferably made of a string-shaped and / or rod-shaped elongated flexible material.

[0006]

The sealing back-up material is interposed at the joint on the cut side of the adjacent hollow molded plate. The convex portion of the sealing backup material fits into the hollow hole, and the base portion contacts the cut portion. That is, the joints between the hollow molding plates are sealed by the base in a state where the hollow holes are closed. In this state, when the sealing material is inserted into the joint gap, the sealing material seals the joint while covering the base portion. That is, the joint is completely sealed by the sealing back-up material and the sealing material, thereby preventing water from stopping. Further, by connecting the male locking member and the female locking member of the pair of sealing backup materials, a sealing backup material having an arbitrary length can be formed. That is, a seal backup material can be formed corresponding to the length of the hollow molded plate used for the outer wall. Therefore, conventional backup materials such as rubber
Soft and easy to deform and leak water
In contrast, the backup material of the present invention
When it is mated, it is slightly deformed.
Because it is restored to the shape of and is harder than the conventional one,
For the part where the backup material and seal material are integrated,
It is said that it is hard to deform as a whole, so the waterproof effect is significantly improved
It has the function of

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the present embodiment, a case where a hollow cement molded plate is used as the hollow molded plate will be described. FIG. 1 is a perspective view showing a schematic structure of a hollow cement molding plate and a sealing backup material, FIGS. 2 and 3 are front and side views of the sealing backup material of the present embodiment, and FIG. 5 and 6 are cross-sectional views of FIG. 4, and FIG. 7 is a perspective view showing a connection structure between the seal backup material and the hollow cement molding plate.

[0008] As shown in FIG.
Is formed of a block-shaped member having a plurality of hollow holes 9, a projection 7 is formed on the upper side, and a recess 8 into which the projection 7 is fitted is formed on the lower side. The hollow holes 9 are square holes in this embodiment, and are arranged at equal intervals in the longitudinal direction. The hollow cement molding plate 6 is formed from a ceramic material. A seal backup material 1 as shown in FIG. 1 is interposed between the cut portions 10, 10 of the adjacent hollow cement molding plates 6, 6.

As shown in FIGS. 2 and 3, the seal backup material 1 has a skewered dango-like front view in FIG. That is, the base portion 2 has a thickness substantially equal to the thickness of the joint between the hollow cement molding plates 6, 6, and the convex portions 3 protruding from both sides of the base portion 2 along the thickness direction of the base portion 2. The convex portion 3 has a contour shape fitting into the hollow hole 9 of the hollow cement molding plate 6, and as shown in FIG. 3, the present embodiment has a square shape. In addition, the convex portion 3
Is not particularly limited. The base portion 2 and the convex portion 3 have the same width in the side shape as shown in FIG. A portion corresponding to the uppermost base portion 2 is formed as a male locking device 4, and a portion corresponding to the lowermost base portion 2 is formed as a female locking device 5.
As shown in the figure, the contour shape of the male locking tool 4 is formed to fit into the female locking tool 5 exactly. Further, the material of the backup material for sealing is formed of, for example, foamed polyethylene, but is not particularly limited as long as it has a suitable strength and is waterproof.

On the other hand, the connection of the seal backup materials 1 and 1 is performed by fitting the female locking tool 5 into the male locking tool 4 as shown in the figure. That is, the fitting portion between the raised portion 7 and the recessed portion 8 and the connecting portion between the male locking device 4 and the female locking device 5 correspond to each other, so that the sealing backup material 1 is interposed and the hollow portion is formed. The above-mentioned sealing state can be maintained regardless of the length of the cement molding plate 6.

In the above embodiment, the shape of the hollow cement molding plate 6 and the shape of the hollow hole 9 are shown in the drawings, but are not limited to these. Further, the shape and dimensions of the sealing backup material 1 are appropriately set according to the shape of the hollow cement molding plate 6. Of course, the shapes of the male and female locking members 4 and 5 of the seal backup material 1 are not limited to those shown in the drawings. Further, as described above, the seal backup material 1 is not limited to foamed polyethylene, but may be any material having appropriate strength and waterproofness, and being elongated. In other words, it has waterproofness and moderate strength
