Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for attaching a decorative cover to an eave ceiling through which a drainage pipe such as a vertical gutter penetrates.

[0002]

[Prior art]

 The verandas of houses need a structure to drain rainwater. FIG. 4 (a) shows a conventional example, in which a through hole 17 is formed by opening vertically in the vicinity of an end of a veranda 10 projecting from a wall surface 21 of a house, and the drain 11 is mounted on the upper surface thereof. There is a mark. An eave ceiling 2 protruding from the wall surface 21 is formed below the veranda 10, and a pipe hole 5 is formed in the eave ceiling 2 near the end on the wall surface 21 side so as to open vertically. Elbows 13 and 14 are connected upside down at both ends of a call pipe 12 formed substantially horizontally, and one end of one elbow 13 is connected to a drain 11 provided in a through hole 17 of a veranda 10, The end portion of the other elbow 14 is connected to the drainage pipe 3 passing through the pipe hole 5. Further, a tubular makeup cover 1 is attached to the lower side of the pipe hole 5, and the gap between the pipe hole 5 and the drainage pipe 3 is hidden by the makeup cover 1. As shown in FIG. 4 (b), the decorative cover 1 is formed of a tubular portion 1a and a flange 1b, and the flange 1b is provided so as to vertically project around the upper side of the tubular portion 1a. The decorative cover 1 is attached by adhering or screwing the flange 1b of the decorative cover 1 and the eave ceiling 2 or by adhering or fitting the drainage pipe 3 passing through the pipe hole 5 and the inner wall of the tubular portion 1a. is there.

[0003]

[Problems to be solved by the device]

 However, when the decorative cover 1 is attached to the outer periphery of the drainage pipe 3 which passes through the pipe hole 5 as described above, when the eave ceiling 2 is formed by ceramic sanding or the like, the flange 1b is formed because the surface is uneven. It is not possible to attach the decorative cover 1 by bonding it to the ceiling 2, and since it is not possible to hit with a screw, it cannot be attached with a screw. When the inner wall of the tubular portion 1a of the decorative cover 1 is adhered and fixed to the outer periphery of the drainage pipe 3 passing through the pipe hole 5, when the drainage pipe 3 passing through the pipe hole 5 is lowered after the drainage pipe 3 is attached, the decorative cover There will be a gap between 1 and the eaves ceiling 2.

The present invention has been made in view of the above points, and an object thereof is to provide a structure for attaching a decorative cover to an eaves ceiling that can eliminate a gap that appears between the decorative cover and the eaves ceiling. To do.

[0005]

[Means for Solving the Problems]

 The decorative cover mounting structure according to the present invention is such that a notch portion 9 is provided on an upper portion of a screw cylinder 4 having a male screw 6 formed therein so that an upper portion of the screw cylinder 4 is elastically contracted and a screw cylinder is formed. A pair of support pieces 8 are projectingly provided on the upper part of the outer surface of 4, and the screw cylinder 4 is inserted into the drainage pipe 3 and is inserted into the pipe hole 5 formed in the eaves ceiling 2 from below so that the upper edge of the pipe hole 5 is inserted. The support piece 8 is locked, the flange 1b is provided on the outer periphery of the upper end of the tubular portion 1a provided with the female screw 7, and the decorative cover 1 is formed. It is characterized in that the female screw 7 is screwed into the male screw 6 of 4 and is attached to the lower side of the pipe hole 5.

[0006]

[Action]

 A notch 9 is provided in the upper part of the screw cylinder 4 formed with the male screw 6 to elastically reduce the diameter of the upper part of the screw cylinder 4 and a pair of support pieces 8 are provided on the upper outer surface of the screw cylinder 4. Projectingly, this screw cylinder 4 is inserted into the drainage pipe 3 and is inserted into the pipe hole 5 formed in the eaves ceiling 2 from below, and the support piece 8 is locked to the upper edge of the pipe hole 5, and the female screw 7 is attached. A flange 1b is provided on the outer periphery of the upper end of the provided tubular portion 1a to form a decorative cover 1, the decorative cover 1 is inserted into a drain pipe 3, and a male screw 6 of a screw barrel 4 is screwed with a female screw 7. Since it has been inserted, the decorative cover 1 can be easily attached to the lower side of the pipe hole 5 of the eaves ceiling 2 by screwing the screw cylinder 4 and the decorative cover 1 together.

[0007]

Embodiments The present invention will be described in detail below with reference to embodiments. The screw cylinder 4 is shown in FIG. A male screw 6 is formed on the side surface of the screw cylinder 4 from approximately the center to the lower end. A pair of opposed notches 9 are formed in the upper portion of the screw cylinder 4, and a pair of support pieces 8 are provided so as to project outward at the upper part of the outer surface of the screw cylinder 4 between the notches 9. The support piece 8 has a rounded inclined surface 8a so that the support piece 8 can be easily inserted into the pipe hole 5 from below, and the notch 9 elastically reduces the diameter.

As shown in FIG. 2B, the decorative cover 1 is composed of a tubular portion 1a and a flange 1b, and the flange 1b is provided so as to vertically project around the upper end of the tubular portion 1a. A female screw 7 is formed on the inner wall of the tubular portion 1a. To attach the decorative cover 1 thus formed, first, the screw cylinder 4 is inserted into the drainage pipe 3 that passes through the pipe hole 5 of the eaves ceiling 2 and inserted into the pipe hole 5 from below. The support piece 8 of the tube 4 is pushed inward, and the threaded tube 4 elastically contracts in diameter. Then, the inward compression of the support piece 8 passing through the pipe hole 5 is released, and the support piece 8 is elastically displaced outwardly and locked to the upper edge of the pipe hole 5 so that the screw cylinder 4 is locked in the pipe hole 5. Attach to. Next, as shown in FIG. 3, the decorative cover 1 is inserted into the drainage pipe 3, and the female screw 7 is screwed into the male screw 6 of the screw cylinder 4 attached to the pipe hole 5, so that the screw cylinder 4 and the screw cylinder 4 are connected as shown in FIG. The decorative cover 1 is screwed. As a result, the eaves ceiling 2 can be sandwiched between the support piece 8 and the flange 1b to fix the screw cylinder 4 and the decorative cover 1. In this way, the decorative cover 1 can be easily attached to the lower side of the pipe hole 5 of the eaves ceiling 2.

[0009]

[Effect of device]

 A notch is provided in the upper part of the male screw threaded cylinder to elastically reduce the diameter of the upper part of the screw cylinder, and a pair of support pieces are projectingly provided on the upper outer surface of the screw cylinder. Insert the drainage pipe into the drainage pipe and insert it from below into the pipe hole formed in the eaves ceiling to lock the support piece on the upper edge of the pipe hole, and then attach a flange to the outer periphery of the upper end of the tubular part with the female screw. A decorative cover is provided to form the decorative cover, and the decorative cover is inserted into the drainage pipe, and the female screw is screwed into the male screw of the screw cylinder. It can be installed under the pipe hole on the ceiling, eliminating the gap between the decorative cover and the eaves ceiling.
