【発明の詳細な説明】 〔産業上の利用分野〕 本発明は建築部材間の接合部の防水法に関する技術で
あり、特に建築物の外壁を成形版により構成する場合の
パネル接合目地部の防水に適するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a technique for waterproofing joints between building members, and particularly waterproofing panel joint joints when an outer wall of a building is formed by a molding plate. It is suitable for.

ケット）による目地防水が行われている。For joint waterproofing of, for example, ALC panels, sidings, concrete precast panels, etc. as a molding plate constituting an outer wall, an irregular-shaped sealing material for construction is generally used. On the other hand, in recent years, buildings in urban areas have narrow gaps between adjacent buildings and passages, making it impossible to provide an external scaffolding, and making it impossible to perform filling work and spatula work from the outer surface of the outer wall of the irregular sealing material. The joints are waterproofed by fixed sealing (gasket).

た外部足場が必須であり使用範囲が限られていた。As shown in FIGS. 7 and 8, the gasket method includes a method in which a gasket 3 is attached to the molding plate 1 in advance and the gasket is positioned in a gap 1d between the molding plates 1.
As shown in FIG. 9, there is a method of inserting the gasket 3 from the outer surface of the outer wall after the mold 1 is erected. In the former method, the gasket 3 attached to the forming plate 1 is easily damaged during the transfer of the panel and during the building, and is pressed against the adjacent forming plate 1 during the building, and the gasket 3 is positioned at a predetermined position in a predetermined shape. The work to make it difficult was not enough waterproofing. In the latter method, there was no room for workers in narrow spaces where the adjacent building gap was narrow, and construction was not possible. In addition, an external scaffold was required, and the range of use was limited.

とを特徴とする。The waterproof property of the joint of the building members according to the present invention is as follows. The gasket made of a polymer elastic material having a flat shape is formed by evacuating the air in the hollow part to reduce the air pressure and contract the air into the joint between the building members. Then, in a joint joint waterproofing method for building member joints in which the hollow portion of the gasket communicates with the outside air to restore the cross-sectional shape of the gasket, the cross-sectional shape of the polymer material elastic body at right angles to the material axis direction is approximately M-shaped and W-shaped are joined up and down, and they are continuous with the left and right surfaces of the gasket of the elastic polymer material in the direction of the material axis of the gasket, and come into contact with the building member from the tip. A gasket provided with an elastic portion having two or more projections is used, and the gasket is inserted into a cavity formed by a groove between building members.

性の信頼性の高い工事ができる。Since the gasket flattened by shrinkage before insertion according to the embodiment of the present invention has a cross-sectional shape in which an M-shape and a W-shape are joined up and down, before and after flattening, the gasket has There is almost no change in the length in the direction, it is easy to insert from the upper part of the cavity formed by the grooves provided between the members into the center of the cavity, and the cavity can be filled with the gasket sufficiently densely. First, the left and right surfaces of the gasket are provided with two or more elastic projections that are continuous in the material axis direction of the gasket and come into contact with the building member from the front end portion. Can be elastically contacted with each other, and waterproofing of joints between members can be performed from the top after setting the members, and highly reliable work of waterproofing can be performed.

スケット中空部分2aに折り畳まれる状態となる。On the other hand, as shown in FIG. 1, the gasket 2 has a cross-sectional shape in which an M-shape and a W-shape are joined up and down, that is, a cross-section symmetrical with respect to the XX axis and the Y-Y axis passing through the center. The outer surfaces of both sides of the gasket are covered with a foam 2f, and two or six projections are provided in this portion in the direction of the material axis of the gasket. A groove 2b is formed at a point where the inner wall of the hollow portion intersects the XX axis. When the end of the gasket 2 in the longitudinal direction is sealed and the hollow portion is evacuated, as shown in FIG. The gasket 2 does not spread in the up-down direction, and the upper and lower portions are folded into the gasket hollow portion 2a.

防止し目地部の防水を行う。Inserting the contracted and flattened gasket along the groove by evacuating the hollow part 2a of the gasket 2 from the upper part of the cavity part 1c formed when several panels are set at a predetermined position with the small edge 1a abutted from the upper part, The vacuum on the top of the gasket is then released (e.g., cut or cut with a cutter, or the end is bent to remove the clipped one). In order to return the gasket to the shape of the free state shown in FIG. 1 by communicating the hollow portion 2a with the outside air, as shown in FIG. The tip end of the protruding portion of the foam 2f elastically contacts, forming a line sealing, preventing infiltration of the joint material back side 1d and waterproofing the joint portion.

(B) shows another example. FIG. 6 shows an example of a longitudinal section.
本発明は、以上説明したように構成されているため、
以下の効果を奏する。Since the present invention is configured as described above,
The following effects are obtained.
部分相互の小口に設けられた溝より構成された空洞部
に、その上部から中空部を真空引きしたガスケットを挿
入することにより、ガスケットは溝に沿って所定位置に
必要長さまで、容易に挿入することができる。By inserting a gasket in which the hollow portion is evacuated from the upper part into a hollow portion formed by a groove provided in the small opening of the partial portion, the gasket can be easily inserted into a predetermined position along the groove to a required length. be able to.
ガスケットの断面形状がＭ字とＷ字を上下に接合した

び寸法を最少限にする設計が可能となり、ガスケットの
復元力を有効に防水性向上に寄与させることができる。Since the cross-sectional shape of the gasket is formed by joining the M and W characters up and down, there is almost no change in the vertical dimension of the cross section of the gasket before and after evacuation of the hollow portion, It is sufficient that the size of the groove of the panel is slightly larger than the size of the gasket in a state where the gasket is evacuated, and it is possible to design to minimize the play size, and it is possible to effectively contribute to the improvement of the gasket's resilience to waterproofness. .

露出しない為、ガスケットの耐久性の心配がない。Further, the position of the gasket in the panel thickness direction can be provided at a predetermined position guided by the groove of the panel, and high waterproofness can be secured. Also, since the gasket is not exposed on the outer surface of the panel, there is no need to worry about the durability of the gasket.

る。Since two or more elastic projections are provided on the surface of the gasket in contact with the panel, double line sealing can be performed between the gasket and the panel, and high waterproofness can be secured. As described above, when a gasket having a special structure is used as in the present invention, a gap between the gasket and the panel is eliminated, high waterproofness is secured, and a seal is secured by the presence of two or more elastic projections. In the case of a seal using only an adhesive, such as an ALC panel, high waterproofness can be ensured even for a member having an improper seal.

After breaking the vacuum of the gasket, waterproofing of the panels between each other in a narrow space, which was previously impossible (because it is difficult to build a scaffold outside the room) And highly reliable waterproofing is possible.
