Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a rim material for an expansion joint device for a building.

``Prior art'' A rim material is provided along the edges of both opposing frameworks, a cover plate is supported on both edging materials to cover the gap between the frameworks, and the side part of the cover plate and the end of the rim material are A common edge member for an expansion joint device for a building with an expansion gasket interposed therebetween is shown in FIG.

That is, the reference numeral 101 is the edge material, and 102
is an expandable gasket, and 103 is a floor. An engagement protrusion 1 is provided in the horizontal direction at the end of the expandable gasket 102.
04, and the corresponding end of the edge material 101 has a horizontal engagement groove 105 for receiving it.
is provided, and an engaging protrusion 104 is fitted therein.

"Problems to be Solved by the Invention" If the expandable gasket 102 and the edge material 101 are connected as shown in FIG. 4, the expandable gasket 102 will not be able to follow the deformation and expansion and contraction caused by earthquakes and will come off. In this case, the floor 103 is finished so that it cannot be inserted from the end in order to fit the engagement protrusion 104 of the expandable gasket 102 into the engagement groove 105 of the edge material 101. It has to be inserted from the beginning, but it is very difficult to insert.

``Means for solving problems'' Therefore, this invention is designed to solve problems regardless of the finish of the floor.
In order to easily insert the telescopic gasket into the edge material, it has a structure that allows it to be inserted from the top and does not easily come off.An engagement groove is provided at the end that opens upward to receive the downward protrusion of the telescopic gasket. The inner side wall of the groove is formed into an engaging protrusion that engages with the receiving groove of the expandable gasket, and a parting member is attached to the end side of the edge member.

"Example" In the extensible part of the building, the frames 1 and 1 face each other, and there is a gap 2. Anchor hardware 4 is fixed by welding to anchor bolts 3 protruding from the upper surface of the frame 1 near the gap 2 at appropriate intervals. The upper end of the anchor hardware 4 is formed parallel to the upper surface of the frame to form a support piece 5.
A bent piece 6 is provided on the inner end side to form a holding groove 7 for the edge material described below. The edge material 8 is a long extruded aluminum material with a roughly square frame-like cross section, and the square frame has a horizontal upper horizontal piece 9, a lower horizontal piece 10, and a vertical inner vertical piece 11 and an outer vertical piece. 12, and the horizontal base piece 13 is formed by extending the upper horizontal piece 9 horizontally. A horizontal piece 15 is made to protrude inward from the lower surface of the end 14 of the horizontal base piece 13 and fitted into the holding groove 7, and a horizontal piece 16 that is made to protrude outward from the lower part of the outer vertical piece 12 is inserted into the cut edge of the anchor hardware 4. The edge material 8 is attached by fitting it into the clamping groove 18 formed by the strip 17.

An expandable gasket 19 is placed on the outer side of the upper horizontal piece 9 of the edge material 8 and on the horizontal base piece 13.

Next, an interior plate 22 made of short aluminum and having a flanges 21 with a slightly narrower width and bent downward at both ends is placed on the inner side of the cover plate 20 made of flat and long stainless steel. The flange 21 is fitted into the support groove 23 at the inner end of the gasket 19, and the cover plate 20 is used to secure the frame 1.
Cover the gap between 1. Upper horizontal piece 9 of the edge material 8
The engagement groove 2 formed by the downward protrusion 24 on the inner end of the
5, engage the end of the spring clip 26, which is a short W-shaped material, and insert the mounting screw 27, which is inserted from the outside to the inside of the cover plate 20, into the spring clip 2.
6. Fix to the roller nut 28 attached to the center.

A water stop plate 30 made of a long vinyl chloride material is fitted into the supporting groove 29 formed below the vertical member 11 of the edge material 8 with the protrusion 31 at the back end thereof to cover the gap between the frames 1 and 1. .

By the way, the end portion 14 of the edge member 8 is provided with an engagement groove 33 that is open at the top and receives the downward protrusion 32 of the expandable gasket 19.
is formed on an engaging protrusion 36 that engages with the receiving groove 35 adjacent to the downward protrusion 32 of the expandable gasket 19. Therefore, the outer end of the expandable gasket 19 is connected by fitting the downward protrusion 32 into the engagement groove 33 from above to below, and at the same time fitting the engagement protrusion 36 into the receiving groove 35.

Further, a stainless steel parting member 37 having a predetermined thickness and made of the same material as the cover plate 20 is screwed onto the side surface of the end portion 14 of the edge member 8 using machine screws 38 .

The parting member 37 is made of the same material as the cover plate 20 to improve the appearance. Further, the presence of the parting material 37 facilitates floor finishing, and furthermore, when the expandable gasket 19 is compressed by the cover plate 20, it is supported so that it does not rise toward the floor.

Reference numeral 39 indicates that the floor finishing material 40 is mortar.

"Effect of the invention" As described above, the present invention provides edge materials along the edges of both opposing building blocks, supports the cover plate on both edge materials to cover the gap between the building blocks, and the cover plate A edging material for an expansion joint device for a building in which an expansion gasket is interposed between a side portion and an end portion of the edging material,
An engagement groove opened upward to receive the downward protrusion of the telescopic gasket is provided at the end, the inner side wall of the engagement groove is formed into an engagement protrusion that engages with the receiving groove of the telescopic gasket, and an engagement groove is provided on the end side of the edge material. This is the edge material of an expansion joint device for a building with a parting material installed, and the connection between the edge material and the expansion gasket is through the fitting of both the downward protrusion and the engagement groove, and the receiving groove and the engagement protrusion. Even if the building expands, contracts, or deforms, it will not come off, and even if it does come off, the connection is easy because all you have to do is insert the downward protrusion of the expandable gasket from above and fit the engaging protrusion into the receiving groove. In addition, since it is possible to attach a parting material to the side of the edge of the edge material, it is possible to use parting materials made of various materials or change the thickness of the parting material, making it compatible with various floor finishes and fittings. can.
Furthermore, the expandable gasket and the floor finishing material can be separated by interposing a parting material.
The parting material can be made of the same material as the cover plate to improve the appearance. Furthermore, the presence of the parting material makes it easy to finish the floor, and furthermore, when the expandable gasket is compressed by the cover plate, it is supported so that it does not bulge toward the floor.
