Description

[Detailed Description of the Invention] The present invention relates to a drainage structure for a rising part of a tower exterior wall or the like on the roof of a building.

In general, this type of drainage structure usually consists of a holder that is attached to the wall of the rising section, a hang cover that is attached to project from the wall of the rising section, and a bracket that attaches the hang cover to the holder in a detachable manner. be. In addition, in this type of drainage structure, it is necessary to prevent the attached hang cover from rattling and rainwater from entering the holder, and furthermore, it is preferable that the hang cover can be attached smoothly.

The present invention was devised in view of these points, and one embodiment of the present invention will be explained below with reference to the drawings.
Reference numeral 1 denotes a holder attached to the wall surface of the rising portion 2. This holder 1 has a U-shaped cross section with an opening on the side, and a hanging piece 4 is provided at the edge of the upper piece 3. 5 is a space surrounded by the upper piece 3, the hanging piece 4, and the back piece 6, and is the upper half of the circumference with a certain point of this space 5 as the center point X, passing through the center point Support pieces 7 and 8 are formed at intervals at the front and rear sides of the vertical line. The support piece 7 has an arc shape along the circumference, is formed to protrude from a position above the lower end edge of the hanging piece 4, and is located at the lower part of the upper half of the circumference,
Further, the support piece 8 is formed to protrude diagonally downward from above the back piece 6 and is located at the upper part of the upper half of the circumference. Reference numeral 9 denotes a protrusion provided on the inner surface of the lower piece 10 of the holder 1, which has an inclination that gradually becomes higher from the edge of the lower piece 10. Reference numeral 11 denotes a hang cover with an inverted L-shaped cross section, in which a horizontal piece 12 is provided obliquely at an angle slightly larger than 90 degrees with respect to the vertical piece 13, and its upper edge is attached to a rising piece 14 at the end thereof. The engaging portion 1 has an arc shape approximately equal to
5 is formed. This engaging portion 15 is slightly larger than a semicircle, and a fixing recess 16 is provided at its lower part. 17 is the vertical piece 1 of the hang cover 11
This is a support recess provided at the lower end of the rear side of No. 3. 18
is a bracket with an F-shaped cross section, and its upper piece 1
9 has an inclination similar to that of the horizontal piece 12 of the hang cover 11, and the end edge is bent 20 upward so as to be fitted into the fixing recess 16. Reference numeral 21 denotes a hook-shaped portion that is engaged with the protrusion 9 of the holder 1, and the lower piece 22
A contact piece 23 is formed on the end edge of the lower piece 10 of the holder 1 at a distance from the hook-shaped portion 21 .

Thus, the holder 1 is attached to the wall surface of the rising portion 2, and the hang cover 11 is provided with a bracket 18 at an appropriate position on the back surface. The bracket 18 has its lower end in the supporting recess 17 and the upper piece 19 in the bent part 2.
0 are fitted into the fixing recesses 16 of the engaging portion 15, respectively. Then, with the hang cover 11 equipped with the bracket 18 at the appropriate place on the back side, insert the engaging part 15 at the upper end into the space 5 of the holder 1, and make the arcuate shape of the engaging part 15 contact the support pieces 7 and 8, and slightly Give a suitable rotation to the hang cover 11 and rotate the bracket 18.
The hang cover 11 is attached by fitting the hook-shaped portion 21 of the holder into the protrusion 9 of the holder 1 using the spring back of the lower piece 22. At this time, the bent portion 20 is pushed up slightly by the spring back of the lower piece 22 and presses the engaging portion 15 against the supporting pieces 7 and 8, thereby preventing the hang cover 11 from shaking in the vertical direction. Furthermore, since the engaging portion 15 is pressed against the support pieces 7 and 8 provided at intervals, rattling in the front-back direction is also prevented.
Overall, movement of the upper part, which is an important part of the attachment of the hang cover 11, is completely prevented, which ensures the secure attachment of the hang cover 11 and prevents the engagement part 15 from moving on the support pieces 7 and 8. Pressure can prevent rainwater or other water from entering through contact. Further, since the support pieces 7 and 8 are provided on the circumference, and the upper edge of the engagement portion 15 of the hang cover 11 is formed in an arc shape, even if the engagement portion 15 is inserted into the space 5, the There is no risk of the parts getting stuck, and even if the hang cover 11 is long, the engaging part 15 contacts the support pieces 7 and 8 and rotates smoothly, making the installation operation of the hang cover 11 easy.

Furthermore, by providing the support piece 7 above the lower end edge of the hanging piece 4, the hang cover 11 comes into contact with the holder 1 in a place where it is not directly exposed to rainwater, thereby preventing direct intrusion of rainwater, etc. It is.

The present invention is constructed as described above, and the hang cover 11 can be installed smoothly without fear of rattling, the installation state is reliable, and the intrusion of rainwater etc. can be prevented. It is extremely useful as a drainage structure for rising parts such as.
