Description

[Detailed Description of the Invention] The present invention relates to a packing for expansion joints in buildings.

Packing for expansion joints in buildings is attached to a cover plate that covers the gap between opposing building blocks, and makes elastic contact with the surface of the building blocks, maintaining a state of contact even when the building blocks expand or contract, creating a watertight structure. It is something. By the way, conventional packings of this type are simply fitted onto both ends of the cover plate and brought into contact with the surface of the building body, but this is not necessarily sufficient for elastic contact of the packing with the surface of the building body. Therefore, in view of the above circumstances, the present invention was developed to further perfect the elastic contact of the packing to the surface of the building structure.
The packing is formed of a U-shaped mounting base and an arc-shaped sealing piece, the inner wall of the mounting base is made of a hard material, the sealing piece is made of a soft material, and the inner wall of the mounting base near the sealing piece is formed into a tapered surface. The regulating piece of the edge material is received, and the sealing piece is brought into elastic contact with the surface of the frame.

Hereinafter, the present invention will be described in detail based on specific embodiments shown in the accompanying drawings.

FIG. 1 is a cross-sectional view of the expansion joint of the building frame, in which the building blocks 1 and 2 are arranged orthogonally with a gap provided therebetween, and in the figure, the upper side is the outdoor side and the lower side is the indoor side.

A rim material 2, which is a long material made of an approximately flat extruded aluminum member, is screwed onto the surface of the frame 1 using round machine screws 3. An upright piece 9 of an angle member 8 that is perpendicular to a rim member 6 that is an extruded aluminum member having a support groove 5 with a groove shape 4 at the base end and an outward opening at the tip end on the edge of the frame 2. The anchor 7 is screwed with a screw 11 through a clamping plate 10 that is in contact with the outer surface of the groove 4 of the edge material 6.
be fixed by welding. The gasket 12 is fitted into the support groove 5 of the edge material 6, and the cover plate 13, which is a long sheet metal material bent at right angles and set to a size that covers the gap between the frames 1 and 2, is attached at both ends. A packing 15 is inserted into the mounting groove 14 which is bent into a U-shape.
is attached so that it comes into contact with the surfaces of the frame 1 and the frame 2, and is brought into contact with the gasket 12, and a protrusion 16 is provided protrudingly on the inner surface of the edge material 2 near the proximal end to form an engagement groove 17. A protrusion 18 is provided protrudingly on the inner surface of the support groove 5 of the member 6 near the proximal end to form an engagement groove 19, and both ends of the W-shaped spring clip 20 are engaged with the engagement grooves 17 and 19 to tighten the mounting bolt. 21 to cover plate 13
The spring clip 20 is inserted from the outdoor side and fixed by screwing onto a roller nut 22 attached to the center of the spring clip 20. Fitting grooves 23 and 24 are formed on the inner surfaces of the base ends of the edge materials 2 and 6, and the gap between the frames 1 and 2 is made into a gutter-like shape and covered with water stop plates 25 made of vinyl chloride on the outer surfaces of both sides. The protruding engagement protrusion 26 is inserted into the fitting groove 2.
3. Attach by engaging with 24.

As shown in FIG. 2, the packing 15 forms a U-shaped mounting base 27 that is fitted into the mounting grooves 14 at both ends of the cover plate 13, and a clamping piece 288 extends from the upper end of the side wall of the mounting base 27 to the bottom of the groove. , and a semicircular arc-shaped sealing piece 29 is continuously provided from the tip of the clamping piece 28,
A large number of engaging protrusions 30 are provided on the outer wall of the mounting base 27 in a protruding manner. In addition, the inner wall of the mounting base 27 is formed of a hard material such as hard vinyl chloride to receive the regulating piece 31 protruding from the tip of the edge material 2 in parallel with the surface of the body 1.
The others are made of soft material such as soft vinyl chloride. The mounting base 27 of the packing 15 is inserted into the mounting groove 14 of the cover plate 13 from the state shown in FIG. . When the packing 15 is attached to the attachment groove 14 of the cover plate 13, the engagement protrusion 30 made of a soft material is sufficiently pressed between the hard material of the inner wall and the cover plate 13. That is, the engagement protrusion 30 is connected to the end piece 32 of the cover plate 13 and the cover plate 1 facing the end piece 32.
3. Strong impact on both sides of the inner wall. Also, sealing piece 2
9 to the surface of the frame 1 with sufficient elasticity under the guidance of the regulating piece 31 of the green material 2.
The inner wall of No. 7 near the sealing piece 29 is formed into a tapered surface 33 having a groove width on the opening side larger than the groove bottom. When the cover plate 13 is moved upward from the state shown in FIG.
3 is guided and approaches the body 1 side, and the sealing piece 29 comes into elastic contact with the surface of the body 1.

In the packing 15 shown in FIG. 4, the mounting base 27 and the clamping piece 28 excluding the bottom outer wall are made of a hard material, and the other bottom outer wall and the sealing piece 28 are made of a soft material.

As mentioned above, the present invention has a U-shaped mounting groove at the tip of the cover plate that covers the gap between the frames.
In the packing that is fitted into the mounting groove, the mounting portion of the packing is a U-shaped mounting base, and a clamping piece is attached from the upper end of the side wall of the mounting base to clamp the end piece of the cover plate forming the mounting groove. A semi-circular sealing piece is extended from the tip of this clamping piece and comes in contact with the surface of the body, etc., and the inner wall of the mounting base is made of a hard material, and the inner wall of the sealing piece is formed with a groove width on the opening side. This is a packing for expansion joints of buildings, which has a tapered surface larger than the groove bottom and a sealing piece made of soft material.The packing elastically contacts the surface of the building structure, etc., and prevents water from entering the expansion joints of buildings. An airtight structure can be provided. In addition, in the present invention, the inner wall of the mounting base is made of a hard material, and the inner wall with a biased seal is formed into a tapered surface where the groove width on the opening side is larger than the groove bottom.
When the cover plate is moved, the tapered surface is guided by the tip of the regulating piece of the edge material and approaches the body, and the sealing piece comes into elastic contact with the body surface, allowing the packing to fully perform its function and making installation easy. It is. Furthermore, since the inner wall side of the packing of the present invention is made of a hard material, when it is installed in a U-shaped groove, if the outer wall side of the mounting base is made of a soft material, it will strongly impact against the U-shaped groove. .
