Description

DETAILED DESCRIPTION OF THE INVENTION The present invention forms an outer wall by connecting a plurality of rectangular outer wall materials in which a plurality of through holes are bored in the longitudinal direction in a row in the vertical direction with the through holes in the horizontal direction. This invention relates to a jointer that is attached to end joints and/or gap joints of external walls.

Extrusion-molded concrete exterior wall materials are usually provided with a large number of parallel through holes in the longitudinal direction in order to reduce the weight and improve heat insulation properties, and these through holes open at the end faces of the exterior wall materials. When the above-mentioned exterior wall materials are installed horizontally and a plurality of them are installed in a row in the vertical direction with the end surfaces with the through holes facing each other, the gap between the opposing end surfaces or the edge contact of the exterior wall with no opposing material. The area is usually filled with a waterproof paste joint material. However, if only such a joint material is used, a large amount of it is used, and furthermore, when the end of the through hole is sealed, the inside of the through hole becomes pressurized or depressurized as the temperature changes, which causes a load to be applied to the joint material. In the worst case, it may even cause breakage and opening. Therefore, it is necessary to lay a back-up material in advance that is thinner than the thickness of the outer wall and does not come into airtight contact with the end face, but almost covers the opening, and then seals the above-mentioned joint material on top of it. embedding material.

Conventionally, as a backup material in such a case, for example, a metal or plastic backup material 1 having a rectangular or inverted trapezoidal protrusion of a constant width is used, as shown in the perspective view and cross-sectional view in FIGS. 1a and 1b. is used. In addition, 2 in the figure is the outer wall, 3
is a through hole, 4 is a sealing material, and 5 is indicated by a two-dot chain line.
is the horizontal beam, and 6 is the stud.

By the way, the contact surface 7 between the backup material 1 and the inner surface of the outer wall 2 has no sealing effect because it is difficult to form a perfect flat surface on the inner surface of the outer wall. Therefore, if the temperature difference between the inside and outside of the exterior wall material is large, moisture that enters from the inside (stud side) will enter the through hole 3 from the contact surface 7 and condense, and over time some of it will be transferred to the concrete that makes up the exterior wall. Penetrate. In cold regions, there is an inconvenience in that the above-mentioned moisture freezes due to a drop in outside temperature, freezes and thaws the concrete, and damages the outer wall.

Intrusion of water into the through holes often occurs when the backup material is made of metal. For this reason,
It is said that condensation of moisture tends to occur on metal surfaces, and the condensed water enters the joints from the contact surface 7, causing the same phenomenon as described above.

In view of the above circumstances, the present invention provides an easy-to-install joiner that prevents moisture or water from entering the through hole from the inside, prevents damage to the outer wall due to freezing of moisture, and does not seal the through hole. The purpose of this project is to provide an edge connection for an external wall, which is formed by connecting rectangular external wall materials in which a plurality of parallel through holes are bored in the longitudinal direction in the horizontal direction and in the vertical direction. A jointer to be attached to a joint part and/or a gap joint part of an outer wall, a large rectangular rigid plate body that closes the bottom of the joint part and abuts the outer surface of the edge of the outer wall, and the outer wall of the large plate body. a rectangular rigid small plate body that is mounted perpendicularly to the abutment surface side, extending in the longitudinal direction of the large plate body and facing in parallel, and abutting the end face of the outer wall edge; an elastic body having a packing function provided along the edge of at least one of the large plates protruding outwardly of at least one of the small plates, and on the surface to which the small plates are attached. The height of the plate is at a height that does not block the through hole of the outer wall to which it abuts.

The present invention will be explained below with reference to the drawings.

FIGS. 2 and 3 show an embodiment of the joiner according to the present invention, with FIG. 2 being a perspective view and FIG. 3 being a cross-sectional view. The reference numeral 11 in the figure is a large rectangular hard resin plate that closes the gap 13 (bottom of the joint) between the end surfaces 12 and 12 of the outer wall 2 and comes into contact with the inner surface of the edge of the outer wall. On the side surface 11a that abuts the outer wall 2, there is a small rectangular hard resin shape that is perpendicular to the surface 11a, extends in the longitudinal direction of the large plate 11, faces parallel to each other, and abuts the end surfaces 12, 12. Plate bodies 14, 14 are integrally attached at a predetermined interval. The heights of these small plates 14 are such that they do not block the through holes in the outer wall 2. Further, a predetermined width and height is provided along the edge of the large plate that projects outward of at least one of the opposing small plates 14, 14 and on the surface on which the small plate is attached. Sano urethane foam 1
6 is attached with adhesive etc. and joiner A
is configured.

Next, a joint forming method using the joiner configured as above will be explained.

First, as shown in the cross-sectional view in FIG. 4, a block-shaped backup material 17 made of olefin resin foam, whose height is lower than the thickness of the outer wall 2, is pushed between the small plates 14, 14 of the joiner A. A so-called "hat joiner B" is formed by fixing it as it is or by adhesive.

Next, when attaching the outer wall 2 to the horizontal beam 5 etc., one protrusion 11b of the large plate 11 of the above-mentioned hatch joiner B is inserted between the outer wall 2 and the horizontal beam 5, and the outer surface of the small plate 14 is attached. end face 1 of outer wall 2
2 for positioning, and then the same applies to other outer walls 2 that are connected in the lateral direction. next,
A sealing material 4 is inserted into the groove 18 formed by the outer wall end surfaces 12, 12 and the upper surface of the backup material 17.
Fill it.

The above explanation is about the method of attaching the joiner when attaching the outer wall 2 obtained by arranging a large number of exterior wall materials in a row in the vertical direction to the horizontal beam. Of course, it is possible to do this, and the construction method can take various forms.

In this case, the urethane foam 16 of Joyner A
has a packing property and has a repulsive force, and is pressed and deformed by contacting the inner surface 2a of the outer wall 2, so that internal moisture and water will not enter the through hole 3 due to the packing effect. In addition, a part of the opening end of the through hole 3 comes into contact with a small rigid plate 14 made of hard resin or the like, and this contact part is set at a height that does not completely block the through hole, so that it is not placed above it. A gap will not be created and the inside of the through hole 3 will not be pressurized or depressurized.

In addition, Fig. 6 a, b, and c show the Hatsuto Joyner B.
As shown in the plan view, side view, and side view of the portion where the joint joiner B contacts the end of the outer wall, the back-up material 17 of the upper and lower engaging portions 19 in the actual joining of the outer wall materials constituting the outer walls 2, 2 is shown. The notch 20 is provided and its height is lower than other parts,
When the sealing material 4 is filled, its upper surface conforms to the surface shape of the outer wall 2 so that it does not protrude.

Furthermore, FIG. 7 shows another example of the joiner A according to the present invention, which is used for the end contact joint of the outermost edge, and the same parts as in the above case are given the same reference numerals. Therefore, the explanation will be omitted. Further, FIG. 8 shows another embodiment of the backup material 17. This has the effect of widening the upper surface and making it easier to receive the sealant 4.

Note that the Joyner A is made by molding a large plate 11 and a small plate 14 by integral extrusion molding of a hard resin such as polyvinyl chloride resin, and pasting the urethane foam 16 thereon. Although synthetic resin foam is used as the backup material 17, other lightweight block materials such as glass wool moldings can be used as the backup material.

As described above, since the jointer according to the present invention has the above-described configuration, it can seal the space between the inner surface of the outer wall, can be easily attached to the outer wall as explained above, and can prevent moisture and water from inside the room. It does not penetrate into the through holes, preventing damage to the outer wall due to freezing and thawing even in cold regions, and seals the through holes, making it possible to perform construction without damaging the joints.
