Description

[Detailed Description of the Invention] The present invention relates to a feature material for a threshold or lintel.

Conventionally, thresholds in which a synthetic resin bottom plate is fitted into the sill groove or a U-shaped groove member is fitted into the fitting groove are known, but in those with a bottom plate fitted, the bottom plate is flat, so Lifting tends to occur, and the groove side surfaces of the sill groove lack protection, and in the case of a U-shaped groove member fitted, the gap created between the groove member and the fitting groove due to a slight processing error is easily noticeable, Therefore, it required a lot of effort to manufacture.

Therefore, the present invention has excellent appearance because the gap between the groove member and the fitting groove is not exposed from the outside, is easy to manufacture, is suitable for protecting the upper edge of the fitting groove, and is suitable for protecting the upper edge of the fitting groove. The object of the present invention is to provide a construction material for a lintel that prevents damage to the protective flange.

Next, an illustrated embodiment of the present invention will be described. This example includes a Shiki-Omoi main body 1 and a groove member 2, and the Shiki-Omoi main body 1 includes:
A required number of bends are provided on the back surface of the substrate 4 using a substrate 4 on which a synthetic resin decorative sheet 3 with a heathered pattern is attached and a core material 6 on which particle boards 5 are laminated with an adhesive. The substrate 4 is bent into a rectangular tube shape by closing the groove 7 with an adhesive, and the outside of the core material 6 is covered with the substrate 4 through the adhesive, and the side edge 8 of the substrate 4 is attached to the bottom surface of the core material 6. It is arranged in

Further, flat groove type fitting grooves 9 are arranged in parallel on the left and right sides of the upper surface of the lintel main body 1, and strip grooves 10 for fixing the retaining pieces are recessed in the outer edges of the groove bottoms of these fitting grooves 9, respectively. .

On the other hand, the groove member 2 is composed of a hard synthetic groove member main body 14 in which the upper edges of adjacent groove side pieces 12 and 12 of the left and right U-shaped groove bodies 11, 11 that match the fitting groove 9 are connected by a connecting piece 13. The main groove member 14 is integrally formed of resin, for example, hard vinyl chloride resin.
At the upper edges of the left and right outer pieces 15, outward facing flanges 16 are formed integrally with the groove member main body 14 using a soft vinyl chloride resin which is a soft synthetic resin of the same type as the hard synthetic resin of the groove member main body 14. However, the tip 17 of the flange 16 is tapered and has a slanting shape as shown by the imaginary line 18, so that the U of the groove member is mainly formed.
A synthetic resin decorative sheet 1 with a heathered pattern similar to that of the decorative sheet 3 on the groove bottom surface of the character-shaped groove body 11 and the top surface of the connecting piece 13.
9 are continuously attached, and a retaining piece 21 with sawtooth-shaped return reservoirs 20 protruding from both sides hangs down from the outer edge of the bottom surface of the U-shaped groove body 11, and the retaining piece 21 and the groove member main body 14 are integrated. is formed.

In this example, the retaining piece 21 of the groove member 2 is pushed into the groove 10 of the lintel main body 1, the U-shaped groove body 11 is fitted into the fitting groove 9 via adhesive, and the tip of the flange is fitted. The upper edge 22 of the fitting groove 9 on the groove side is concealed and closed by the flange 16 by bending the portion 17 slightly upwardly and closely contacting the top surface of the main body 1, and the tip of the serrated recess 20 of the retaining piece is straightened. A retaining piece 21 is bitten into the side surface of the groove 10 to prevent it from being pulled out upward.

In this embodiment of the shiki lintel, since the upper edge 22 of the fitting groove on the groove side is hidden and closed by the flange 16, a fitting gap is created between the groove side surface of the fitting groove 9 and the groove member 2. Even if the mating gap is exposed from the outside, the fitting gap is not exposed from the outside and has an excellent appearance, and the decorative sheet 3, which is mainly made of shikikomoi, is prevented from peeling off from the upper edge 22 on the groove side. If something gets caught on something, the tip 17 that gets caught on something will fall on the imaginary line 2 because the flange 16 is made of soft synthetic resin.
As shown at 3, the flange 16 is temporarily bent upward to prevent damage to the flange 16.

Furthermore, in this example, even if the groove member 2 tries to float up, the retaining piece 21 having the return reservoir 20 prevents the upward movement, thereby preventing the above-mentioned floating.
The U-shaped groove body 11 can be easily attached to the bottom, and the flange 1 can be easily attached to the bottom.
6 can be easily brought into close contact with the shikikomoi main body 1 in a bent state as described above, and also, as described above, peeling of the groove side upper edge 22 of the shikikomoi main body decorative sheet 3 is prevented. The main body 1 of the shikimoi is attached to the base plate 4 with the decorative sheet 3 as described above.
It can be manufactured at low cost by using a plate material with a core material 6 such as particle board and the like.

The groove member main body 14 made of hard synthetic resin and the flanged portion 16 made of soft synthetic resin can be easily formed into one piece by extrusion molding, and the groove member main body 14 in the above example is made of plasticizer 10.
A vinyl chloride resin containing ~15% of a plasticizer was used as a raw material, and a vinyl chloride resin containing about 40% of a plasticizer was used for the flange portion 16, respectively.

Also, it goes without saying that if the material for the lintel used in this project is to be used for a lintel, the entire top and bottom should be reversed.

In addition, although the groove member has two U-shaped grooves in the above example, it can also be applied to one or three or more U-shaped grooves.

As mentioned above, the feature material for a lintel of the present invention has a fitting groove on the upper surface of the main part of the lintel, and a U-shaped groove body that matches the fitting groove on the outer side of the synthetic resin groove member. A flange made of a soft synthetic resin similar to the synthetic resin is integrally formed on the upper edge, a U-shaped groove body of the groove member is fitted into the fitting groove of the main body of the shikimooi, and the flange of the groove member is The feature is that the upper edge of the groove side of the mating groove, which is mainly made of shikimooi, is hidden and closed, and the fitting gap between the groove side of the mating groove and the groove member is not exposed from the outside, giving it an excellent appearance and easy production. The upper edge of the fitting groove, which is easily damaged, can be protected by the flange, and the flange itself can be prevented from being damaged due to catching or the like due to the flexibility of the soft synthetic resin.
