Description

[Detailed Description of the Invention] The present invention relates to a ceiling circumference device used in a melting chamber or the like.

In the case of a ceiling edging device in a place where condensation water occurs on the ceiling material such as a conventional welding room, as shown in FIG. 1A, a standing piece 5' is erected on the top end of a horizontal piece 4' of a edging 3' extending from the top end of a wall surface 1 toward the bottom surface of the edge of a ceiling material 2, and a soft fin piece 9' is provided at the top end of the standing piece 5'.
In the conventional example shown in Fig. 1a, in a place where condensation water is likely to occur on the ceiling material 2, such as a welding room, the condensation water flows as shown by the solid line in Fig. 1a, and the condensation water accumulates over the entire underside of the skirting 3' due to surface tension, causing water stains to form in this area,
In the conventional example of Fig. 1b, not only does a portion of the condensation water flowing along the underside of the ceiling material 2 flow over the entire underside of the rim 3' as shown by the solid line arrow in Fig. 1b and accumulate there due to surface tension, causing the entire underside of the rim 3' to become dirty with water stains, but another portion of the condensation water flowing along the underside of the ceiling material 2 penetrates into the rim 3' from between the underside of the ceiling material 2 and the upper end of the standing piece 5' as shown by the dashed line arrow in Fig. 1b, causing water to penetrate into the cut end face of the ceiling material 2.

The present invention was devised in view of the above-mentioned problems, and its purpose is to create a ceiling circuit in which the lower surface of the circuit board does not get dirty and the cut end surface of the ceiling material is not damaged by water. There is a rim device to provide.

The ceiling circumference device of the present invention extends the horizontal part 4 of the circumference 3 from the upper end of the wall surface 1 toward the lower surface of the edge of the ceiling material 2, and extends the horizontal part 4 of the circumference 3 from the upper end of the wall surface 1 toward the lower surface of the edge of the ceiling material 2. 5 is erected, and at the same time, an inner vertical piece 6 is erected on the upper surface of the tip of the horizontal piece 4 in parallel with the outer vertical piece 5, and a gutter groove 7 is formed between the external vertical piece 5 and the inner vertical piece 6. A gap 8 is formed between the upper end of the outer upright piece 5 and the lower surface of the ceiling material 2, and a soft fin piece 9 provided at the upper end of the inner upright member 6 is brought into elastic contact with the lower surface of the ceiling material 2 in a watertight manner. By adopting such a configuration, the above-mentioned object of the present invention is achieved. In other words, the condensed water flowing from the ceiling material 2 flows through the gap 8 into the gutter groove 7, which prevents the condensed water from flowing onto the lower surface of the circumference 3 and staining the entire lower surface of the circumference 3 with water scale. Also, even if water tries to flow along the lower surface of the ceiling material 2 from the gutter groove 7 portion to the cut side end surface of the ceiling material 2, the soft fin pieces 9 come into elastic contact with the lower surface of the ceiling material 2, and the water flows into the ceiling material 2. Water is prevented from flowing toward the cut side end surface of the ceiling material 2, and the cut side end surface of the ceiling material 2 is prevented from being soaked with water.

The present invention will be explained in detail below with reference to Examples. Circumcision 3
As shown in FIG. 3, it consists of a circumferential body 10 and a body holding portion 11, and is made of a synthetic resin such as hard polyvinyl chloride into a long length. Circumference body 1
0 is an outer vertical piece 5 along the top surface of the tip of the horizontal piece 4.
is erected, and an outer vertical piece 5 is placed on the upper surface of the tip of the horizontal piece 4.
An inner vertical piece 6 is erected in parallel with the inner vertical piece 6, and a soft fin piece 9 made of soft polyvinyl chloride or the like is integrally molded on the upper end of the inner vertical piece 6.
A gutter groove 7 is formed between the horizontal piece 4, and a connecting piece 12 is erected on the upper surface of the base end of the horizontal piece 4 in parallel with the inner and outer vertical pieces 6, 5, so that both outer surfaces of the connecting piece 12 are connected to each other. This tooth-shaped stepped surface 13 is provided in the cross section. The main body holding part 11 has a groove part 14 hanging down so as to face the connecting piece 12 of the circumferential main body 10, and the inner surface of the groove part 14 has a serrated cross section that can engage with the stepped surface 13 of the connecting piece 12. A stepped surface 15 is provided.

As shown in FIG. 2, nails 17 are driven into the lower surface of the base material 16 arranged around the ceiling to fix the main body holding part 11 at the ceiling position, and after the ceiling material 2 is installed, the main body holding part The circumference main body 10 is placed in the groove portion 14 of 11.
The connecting piece 12 is inserted, and the insertion depth of the connecting piece 12 is adjusted to bring the soft fin piece 9 into elastic contact with the lower surface of the ceiling material 2 in a watertight manner, and the upper end of the outer vertical piece 5 and the ceiling material 2
A gap 8 is formed between the lower surface and the lower surface. Water droplets condensed on the lower surface of the ceiling material 2 flow along the ceiling material 2 and enter the circumference 3 through the gap 8, but are blocked by the soft fin pieces 8 and can no longer penetrate inside. Gutter groove 7
It flows inwards and accumulates. The water accumulated in the gutter groove 7 is drained by, for example, flowing through the gutter groove 7 and dripping downward from the longitudinal end of the circumference 3. In this case, since the end portion of the circumferential rim 3 drips at the corner portion of the chamber such as the solution chamber, it is not noticeable even if this portion becomes slightly soiled.

As described above, the present invention extends the horizontal part of the circumference from the upper end of the wall surface toward the lower surface of the edge of the ceiling material, and the outer vertical part is erected along the upper surface of the tip edge of the horizontal part, and An inner vertical piece is erected on the upper surface of the tip of the piece in parallel with the outer vertical piece, a gutter groove is formed between the outer vertical piece and the inner vertical piece, and a gutter groove is formed between the upper end of the outer vertical piece and the lower surface of the ceiling material. Since a gap is formed in the ceiling material, the condensed water flowing from the ceiling material flows into the gutter groove through the gap.
As a result, condensed water flows onto the lower surface of the circumference, staining the entire lower surface of the circumference with limescale, which is an unheard of situation. Furthermore, since the soft fin piece provided at the upper end of the inner vertical piece is brought into elastic contact with the lower surface of the ceiling material in a watertight manner, water is prevented from flowing along the lower surface of the ceiling material toward the cut end surface of the ceiling material. This prevents the cut side end surface of the ceiling material from getting wet with water.
