Description

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

Expansion joint devices for buildings must have a completely watertight structure that covers the gaps no matter how the building frame expands or contracts. Therefore, the present invention was developed with the aim of maintaining a completely watertight structure at all times no matter how the frame expands or contracts.

Hereinafter, the present invention will be described with reference to specific embodiments shown in the accompanying drawings.

On the upper edges of both of the opposing bodies 1, there is a rim material 4 made of a long aluminum alloy extruded shape with an almost angular cross section extending back and forth, consisting of a rising piece 2 and a horizontal piece 3, and a rising piece 2 is placed on the upper edge of the opposing body. Then, arrange them in parallel and screw them onto the frame 1 using round machine screws 5 and nuts 6. A locking piece 7 is provided horizontally outward at the upper end of the rising piece 2, and a support piece 8 longer than the locking piece 7 is provided horizontally outward on the rising piece 2 below the locking piece 7. .

The intermediate material 9 is a long material made of aluminum alloy, which has an upright piece 10 and a diagonal base piece 11 arranged at the base end of the upright piece 10 so that the outer side is gradually downward. An engaging piece 12 that projects horizontally from the outside of the connecting part with the horizontal piece 3 is provided with an engaging piece 13 that hangs downward from the connecting part between the upright piece 10 and the base piece 11 and projects horizontally. Engage horizontal piece 3 of edge material 4
Engagement protrusion 1 horizontally protruding outward from the outer end
4, the intermediate member 9 is fixed by engaging the engaging protrusion 15 horizontally protruding inside the lower end of the base piece 11.
A horizontal locking piece 16 is provided inward at the upper end of the rising piece 10 of the intermediate material 9, and a support groove 17 is formed by the locking piece 7 of the rising piece 2 of the edge material 4 and the support piece 8. A gasket 18 is fitted into the support groove 17.

A flat cover plate 19 made of a long metal plate with a substantially U-shaped cross section and extending back and forth is set to a size that covers the gap between the building blocks 1, is placed on the gasket 18, and is placed on the edge material 4. Both ends of the W-shaped spring clip 22 are engaged with the downward groove 21 in which the protrusion 20 is vertically provided inside the support groove 17, and the hexagonal bolt 23 inserted from the outdoor side to the indoor side of the flat cover plate 19 is inserted into the spring. It is fixed by screwing onto a roller nut 24 attached to the center of the cup 22. In addition, a connecting groove 25 is formed inside the connecting part between the rising piece 2 and the horizontal piece 3 of the edge material 4, and a water stop plate 26 made of vinyl chloride extending from front to back is used to cover the space between the frame members 1 in a gutter-like manner on both sides. Protrusion 27 protruding from the outer surface
is locked in the engagement groove 25.

The edging material 28 is a metal plate that extends from the top of the rising piece 2 of the edging material 4 to the horizontal piece 3 and covers the upper surface of the frame 1 with an intermediate material 9 interposed therebetween. A diagonal piece 30 is arranged at the base end so that the outer side gradually becomes downward, and a hanging piece 31 and a horizontal piece 32 facing inward are sequentially arranged at the outer end of the diagonal piece 30. In the edging material 28, the horizontal piece 32 is engaged with a groove 33 carved below the engagement protrusion 14 on the outer end of the horizontal piece 3 of the edging material 4, and the vertical piece 29 and the diagonal piece 30 are connected to the upright portion of the intermediate material 9. abut against the outer surfaces of the piece 10 and the base piece 11, respectively,
The screw 34 is inserted into the vertical piece 29 from the outside and screwed onto the upright piece 10.

The lower portions of both ends of the flat cover plate 19 are bent outward in a diagonal manner.

Reference numeral 35 is caulking.

As described above, in the present invention, the edging material is arranged so that the rising piece is located at the edge of the upper surface of both opposing body parts, and the upstanding piece of the intermediate material, which is engaged and fixed to the horizontal piece of the edging material, is A gasket is fitted between the rising end of the edge material and the rising end of the intermediate material, and a flat cover plate with a U-shaped cross section is placed on the outside of the frame so as to cover the gap between the frames. A slanted piece is placed and fixed on the gasket, and the lower end of the slanted piece is connected to the edge material of the intermediate material. This is an expansion joint device for a building in which the engagement fixing part for the horizontal piece is covered and locked in the groove at the outer end of the horizontal piece, and the vertical piece is screwed in contact with the outer surface of the upright piece. Even when the frame expands and contracts back and forth, the gap between the frames is covered by the flat cover plate, and the gasket at the upper end of the edge material is in contact with the inner surface of the flat cover plate, resulting in a completely watertight structure. Also,
In the present invention, even if rainwater enters between both ends of the flat cover plate and the rim material, the rim material is formed into a vertical piece and a diagonal piece, so it will not be drained outside and reach the inside. There are none.
