Description

[Detailed explanation of the idea] The present invention relates to the structure of attaching the backing.

This type of backing belongs to the type of backing for preventing fluid leakage, but is called an airtight backing or a watertight backing depending on whether it is used for air or water.

In addition, there are two types of use: cases in which a backing attached to a panel is brought into direct contact with a panel or other member, and cases in which the above-mentioned backing is brought into contact with another backing attached to a panel or other member. includes both.

Hereinafter, a prior example of a backing mounting structure will be explained with reference to the drawings. In the prior example shown in FIG. 1, a groove 2 is formed by extrusion molding or the like in the part of the panel 1 where the backing is to be attached, and the groove 2 is elastically fitted into the groove 2. A backing 3 made of a shaped elastic material, for example soft rubber or synthetic wood, is fitted.

In another prior example shown in FIG.
The flat attachment part 6 is extended along the panel 7 to which the backing is to be attached, and the attachment part 6 is fixed to the panel 7 with screws using a flat holding plate 8.

This type of structure has a simple structure for the backing body, but in the former case, it is necessary to form a groove in the panel in advance, and if the backing is to be installed at the end or corner of the panel, the groove It was difficult to mold.

In addition, in the latter case, it is difficult to position the presser plate on the backing, so when installing the backing and the presser plate, the backing and the presser plate must be positioned and then fixed with screws, which requires a lot of effort.

In addition, since the holding plate is a thin flat plate, each installation creates gaps between the screws, and when the panel with the backing attached is attached to a building, etc., the tight part collides with other parts and rolls up as shown by the broken line. there were.

The purpose of this invention is to eliminate the above-mentioned drawbacks.The backing is made up of two tight parts, and push plates shaped to fit the recesses are fitted into the four upward channel-shaped places between the two tight parts. Furthermore, the push plate is screwed to the panel so that the backing can be closely fixed on the panel by using the flat surface of the bottom of the backing.

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

FIG. 3 shows the cross-sectional shapes of the elongated backing 11 and push plate 12 made of an elastic material such as soft synthetic rubber or synthetic resin.

The backing 11 includes a substrate 13 with a straight lower edge, and tight parts 15 and 16 formed in the shape of glasses on the substrate via a channel part 14.

The key portion 17 at the right end of the board is an auxiliary portion that is engaged with the edge portion of the panel 21 and used for positioning the backing 11.

Furthermore, the tongue-shaped part 18 at the left end of the board is an auxiliary tight part extending diagonally downward to the left from the vicinity of the connection part between the tight part 15 and the board 13, and makes airtightness and watertightness more complete at the left end between the panel 21 and the board 13. It was established to do so.

In this embodiment, the push plate 12 is made of a rigid material and has a downward channel cross-sectional shape, with outer surfaces 12 a of both side walls,
The distance B between 121 is sized to fit within the inner width A of the channel portion 14 of the backing.

When attaching the backing to the panel, the key part 17 is engaged with the edge of the panel to position the backing with respect to the panel (Fig. 4), and the push plate 12 is inserted into the recess of the channel part 14.
and connect it to the panel 21 by passing the screws 22 through holes (not shown) provided in the push plate.

Since both outer surfaces 12a, 12a of the push plate 12 are inscribed in the recesses of the channel portion, the tight portion does not curl up during installation as in the prior example shown in FIG.

Further, since the push plate has a downward channel shape, the backing and the panel have good adhesion in the longitudinal direction, and no gap is created between them.

Furthermore, compared to the previous example, there are two tight parts 15 and 16, so when used for watertight purposes, for example, even if rainwater or the like tries to enter the interior by passing through one tight part by capillary action, the channel part Since the space in the 14 recesses has expanded, capillary action is cut off at this location and no further intrusion into the interior occurs.

It goes without saying that the two tight parts are more effective for airtightness.

In this embodiment, a downward channel shape is used, but in order to simplify the structure, a square cross-sectional shape can also be used.

FIGS. 5 and 6 show examples in which the mounting structure of the present invention is used for a curtain wall.

In this embodiment, the mounting structure of the present invention is applied for airtightness, and the upper and lower panels 31°3 forming a curtain wall
2 or the left and right panels 33, 34, respectively, are fixed with pairs of backings 11 at opposing joints located on the indoor side.

Spaces Vl and V2 are formed between the upper and lower panels and between the left and right panels, respectively, so that the pressure is equal to the outside air, so rainwater is trapped in the space ■1. (2) There is little intrusion into the backing 2, and furthermore, the pair of backings 11 abut each other to achieve a complete airtight seal.

In addition, 35 in Fig. 6 is a caulking 3 that connects the left and right panels 33 and 34 through blocks 36 and 36 that are fixed to them.
The number 7 is wood.

Since the present invention is constructed as described above, there is no need to form a groove in advance in the mounting portion of the backing, and the backing can be mounted at any desired location.

Further, the tight portion is prevented from turning up by the holding plate, and the backing maintains a predetermined shape.

Furthermore, since there are two tight parts, it not only ensures airtightness and watertightness, but also has many advantages such as easy installation because the holding plate only needs to be placed in the channel-shaped recess between the two tight parts. vinegar.
