Description

[Detailed Description of the Invention] The present invention relates to an expansion joint device for the outer wall or floor of a building.

Conventionally, as shown in FIG. 1, an expansion joint device for a building fixes edging materials 2 to the mutually opposing edges of a building frame 1 at a joint portion of a building.
A cover plate 3 that covers the gap between the two is supported by the edge material 2 so that a gasket 4 provided at the side end of the cover plate 3 comes into contact with the surface of the frame 1. By the way, when the surface of the frame 1 is uneven as shown in FIG. 2, a gap is created between the surface of the frame 1 and the edge of the cover plate 3, causing water intrusion. Therefore, in view of the above-mentioned circumstances, the present invention has been developed by actively positioning the cover plate that covers between the building blocks with its side edges on the edge material whose plane is completely smooth so as not to be affected by the flatness of the building body surface at all. Its biggest feature is that it has been designed to

Hereinafter, the present invention will be explained in detail based on a specific embodiment shown in FIGS. 3 and 4.

A reinforcing bar 6 is inserted vertically (perpendicular to the page) into the center of the opposite side surface 5a of the frame 5, and the corners on both sides are omitted (not shown in the drawing). In the figure, the upper side is the outside of the building and the lower side is the indoor side.

The U-shaped anchor 7 is made of sheet metal, and is bent in the same direction on both sides of the base piece 7a so that it is fitted externally to the opposite side surface 5a of the frame 5, as shown in FIG.
form b. A receiving piece 8 is formed by cutting and raising the base piece 7a outward approximately in the center to support one end of the edge material, which will be described later, and its tip is further bent outward to facilitate insertion of one end of the edge material. . The central part of the side piece 7b bulges outward, and a female screw 9 for screwing a border material or a cover plate is carved into the bulged part, and the tip of the side piece 7b is externally fitted into the opposite side surface 5a of the frame 5. bend outward to facilitate

A plurality of these U-shaped anchors 7 are externally fitted at appropriate intervals to the opposite side surface 5a of the frame 5 so as to cover the side surfaces, and the center inner surface of the base piece 5a is fixed to the reinforcing bar 6 by welding, or It is fixed by screwing from above the side piece 7b at a position away from the side surface 5a.

A vertical piece 10a of a rim member 10 made of an extruded aluminum alloy member running along the edge of the frame 5 with a generally right-angled cross-section is inserted into the receiving piece 8 of the U-shaped anchor 7, and the other horizontal piece 10b is placed on the side. Screw into the female screw 9 of the piece 7b with the mounting screw 11. The horizontal piece 10b is supported by the bulging part and the bent part at the tip of the U-shaped anchor 7, and is spaced apart from the frame by a size that allows watertight work such as caulking to be performed. Since this edge material 10 is an extruded aluminum alloy member, its surface is completely smooth.

The cover plate 12 that covers between the edge materials 10 at the edges of the frame 5 is a generally flat extruded aluminum alloy member, and its both ends are set to be located on the horizontal pieces 10b of the edge materials 10, and the inner surfaces of both ends A watertight gasket 13 is held in the groove, and the gasket 13 is brought into contact with the surface of the horizontal piece 13b to cover between the edge materials 10.

Both ends of the W-shaped spring clip 15 are engaged with the engaging pieces 14 protruding from the base end of the vertical piece 10a of the edge material 10, and the center part of the spring clip 15 is attached to the cover plate 12 with the mounting bolt 16. The cover plate 12 is screwed in and pulled toward the edge material 10 and fixed.

A gasket 16 is fitted into the groove on the proximal end side of the horizontal piece 10b of the edge member 10, and is brought into contact with the inner surface of the cover plate 12 to form a watertight structure. In addition, each edge of a water stop plate 18 made of vinyl chloride is engaged with an engagement groove running over the entire length of the vertical piece 10a of the edge member 10, thereby preventing rainwater from entering from the joint portion.

On the other hand, the joint part on the indoor side has a cover plate 19 made of sheet metal that covers the frame 5 and has a generally flat cross section.
A mounting screw 20 is screwed into the female thread 9 of the side piece 7b of the U-shaped anchor 7 on only one side. In addition, code 2
1 indicates the caulking part.

Even if the distance between the two frames is changed within the allowable range, the joint part of the building is covered with a cover plate in a watertight manner. As mentioned above, in the present invention, the cover plate that covers between the building blocks is attached to the edge material so that its side edges are positively positioned on the edge material. In contrast, the surface of the edge material is completely smoother than the surface of the frame, and there is no gap between the side edge of the cover plate and the edge material, and no rainwater or the like can enter. Extend one horizontal end of the edge material far enough into the gap from the side piece of the U-shaped anchor, and place it away from the body of the U-shaped anchor.
Since the side pieces of the character-shaped anchor are covered, sufficient caulking can be applied between one horizontal end of the edge material and the structure having an uneven surface, and the expansion joint device becomes a watertight structure.

In addition, due to the distance between the uneven surface of the frame and the horizontal section 1
0b, the horizontal piece 10b is kept smooth, and the gaskets 13 at the side ends of the cover plate are in close contact with the surface.
