Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal joint waterproof structure between upper and lower vertical hollow-extruded cement boards.

[0002]

2. Description of the Related Art A vertical hollow-extruded cement board is sometimes used to form an outer wall of a building. In that case, as a horizontal joint waterproof structure between the upper and lower cement boards, as shown in FIG. The water W that tries to enter the back side of the plates 51 and 52 is received by the draining plate 53 disposed between the upper and lower cement plates 51 and 52, and the water W received by the draining plate 53 of the lower cement plate 52 is received. It is provided so as to be poured into the hollow portion 52a.

In this waterproof structure, since the sealing material 54 is filled from the front side in the lateral joint between the upper and lower cement plates 51, 52, the hanging plate portion 53a of the draining plate 53 is used.
On the front side, a back-up material 55 having water-flowing irregularities 55a on the back side is installed. The unevenness 55a forms a water passage portion 56 penetrating in the up-down direction between the backup material 55 and the draining drooping plate portion 53a.
The water received by the lower cement plate 5 is passed through the water passage portion 56.
The backup material 55 receives the sealing material 54 while pouring it into the second hollow portion 52a.

[0004]

By the way, the above-mentioned backup material 55 can be pre-attached to the front side of the drooping plate portion 53a of the draining plate 53, or the upper and lower cement plates 51 can be attached in advance. , 52 can be erected and then pushed into the interior of the horizontal joint from the front side for post-installation work, but in any case, the backup material 55 is installed in the draining plate 53 so that the backup material 55 is in a stable installation state. It is preferable that the hanging plate portion 53a is attached to the front portion of the hanging plate portion 53a.

However, if the side of the backup material 55 on which the irregularities 55a for water passage are provided is cleanly attached to the front surface of the hanging plate portion 53a of the draining plate 53, the backup material 55 has elasticity. Since it is a non-hard material that is easily deformed, there is a problem that it is quite difficult and time-consuming regardless of whether it is first-attached or later-attached.

In view of the above-mentioned conventional problems, the present invention allows water received by the draining plate to flow into the hollow portion of the lower cement plate, and moreover, backs up the front side of the hanging plate portion of the draining plate. It is an object of the present invention to provide a horizontal joint waterproof structure between vertically-extending vertical hollow-extruded cement boards, which enables proper and easy attachment of materials, as well as easy filling of sealing materials. And

It is designed to flow in, and the front side of the second backup material is filled with a sealing material that closes the space between the upper and lower cement plates. It is solved by the ground waterproof structure.

In this structure, the water received by the draining plate is not formed between the hanging plate portion of the draining plate and the first backup material, but is formed between the first backup material and the second backup material. Through the part, it can flow into the hollow part of the lower cement board.

In addition, since the back side of the first backup material attached to the front side of the drooping plate portion of the draining plate is a laterally continuous surface that does not repeat unevenness in the lateral direction, the drooping plate of the draining plate is The first backup material can be properly and easily attached to the front surface of the section.

In addition, since the second backup material is interposed between the first backup material and the sealing material, even if the sealing material is firmly filled in the horizontal joint, the water passage portion is blocked. The sealing material can be easily filled without causing such a problem.

The second backup material may be attached to the first backup material, or may be abutted without being attached. Since the first backup material is attached to the hanging plate portion of the draining plate, the uneven shape on the front side is stable, and the second backup material is
It can be properly and easily attached to the front side uneven surface of the backup material, or can be properly and easily abutted even when not attached.

Further, the above-mentioned problem is a drainer plate which is provided so as to extend laterally between upper and lower vertically-extending hollow extruded cement plates, wherein the rising plate portion and the rising plate portion along the lower end rear surface of the upper cement plate are provided. A horizontal overhanging plate portion that projects from the lower end along the lower surface of the upper cement plate, and one that includes a hanging plate portion that hangs downward from the tip of the horizontal overhanging plate portion, and a draining plate that is laterally extended. The back part is attached to the front part of the hanging plate part, and this back part consists of a laterally continuous surface part that does not repeat unevenness in the lateral direction,
Further, the front side is provided with a non-rigid backup material provided with water-flowing unevenness forming a water-flowing portion that causes the water received by the draining board to flow into the hollow portion of the lower cement board. The same problem can be solved by a draining material for horizontal joint waterproofing between the upper and lower vertically-extended hollow extrusion molded cement boards, which is characterized in that.

That is, in this draining member, the water received by the draining plate does not fall between the hanging plate portion of the draining plate and the first backup member but through the water flow unevenness on the front side of the first backup member. It can flow into the hollow part of the side cement board. Moreover, since the back side of the first backup material attached to the front side of the drooping plate of the draining plate is a laterally continuous surface that does not repeat unevenness in the lateral direction, the front side of the drooping plate of the draining plate is The first backup material can also be properly and easily attached to the portion.
