Description

  The present invention relates to a drain pipe mounting structure for mounting a drain pipe protruding from a wall surface of a building to a water collecting basin.

Conventionally, drainage pipes for draining rainwater from balconies, flat roofs, etc. are installed through the wall of the building, and this drainage pipe is attached to the water collecting and draining structure, and various structures are known. The technique described in Document 1 can be cited. In Patent Document 1 below, as shown in FIGS. 1 and 2, the mounting cylinder 3 is fitted on the outside of the drain pipe 2, and the mounting cylinder 3 is fixed to the wall surface 1. In the drainage drainage mounting device in which the drainage drainage main body 4 is protruded laterally from the drainage drainage main body 4 and connected to the drainage drainage mounting apparatus, the gap between the mounting cylinder 3 and the drainage pipe 2 is set. Further, a drainage drainage attachment device is disclosed in which packing materials 6 and 7 for sealing the gap are interposed, and an inner ridge protrusion 8 is provided on the inner peripheral edge on the wall surface 1 side of the mounting cylinder 3 so as to protrude over the entire circumference. Has been.

  However, in the structure described in Patent Document 1, it is difficult to construct according to the thickness of a drain pipe having a different outer diameter depending on the construction site, and a mounting structure or the like suitable for drain pipes having other diameters is prepared each time. There is a need to. The present invention solves such a problem, and can be attached corresponding to the thickness of the drain pipe that varies depending on the construction site, and from the gap between the drain pipe and the drain pipe insertion hole provided in the water collecting basin. It is an object of the present invention to provide a drain pipe attachment structure capable of preventing jumping of water such as rebounding and scattering of drainage.

  In order to solve the above problems, the present invention takes the following technical means. That is, according to the present invention, a drain pipe projecting from the wall surface of a building is attached to a water collecting basin, and the mounting structure is provided on the wall fixing portion fixed to the wall surface and the water collecting basin. A drainage pipe mounting structure in which the drainage pipe is inserted through the cylindrical body part and a rubber gasket for preventing splashing is provided at the end of the cylindrical body part. Is provided.

  The water splash preventing rubber packing is a continuous body of triangular packing formed by cutting radially from the substantially central portion of the rubber packing, and the substantially central portion is a free hole through which the drain pipe is inserted. The The rubber packing is not particularly limited, but a synthetic rubber packing having excellent water resistance and flexibility is preferably used. In addition, the wall surface fixing portion, the cylindrical body portion, and the water splash preventing rubber packing may be equally divided into left and right, and each divided body may be swingable around a fulcrum provided at the upper portion of the wall surface fixing portion. .

  The drain pipe mounting structure according to the first aspect of the present invention is as described above, and includes a cylindrical body portion and a wall surface fixing portion that are attached to a drain pipe insertion hole provided in a water collecting basin. Since the drain pipe is inserted through the inside of the part and a rubber gasket for preventing jumping is provided at the end of the part, even if the diameter of the drain pipe differs depending on the construction site, as long as the inside of the cylindrical part is inserted, there are various It can correspond to the drain pipe of the thickness. In addition, by fixing the wall surface fixing portion to the wall surface, the drainage pipe mounting structure itself can be firmly fixed to the wall surface without using a bayonet fitting or the like.

  The rubber gasket for preventing water splash is a continuous body of triangular packing formed by cutting radially from the substantially central portion of the rubber packing, and the substantially central portion is a free hole through which the drain pipe is inserted. Therefore, even if the diameter of the drainage pipe is different, the triangular packing continuum will follow correspondingly, preventing the jumping of water such as splashing and scattering of drainage from the water collecting around the drainage pipe, Prevents walls from getting dirty.

  Since the wall surface fixing portion, the cylindrical body portion, and the water splash preventing rubber packing are equally divided into left and right, and each divided body is swingable around a fulcrum provided at the upper portion of the wall surface fixing portion. When it is difficult to insert the inside of the cylindrical body portion as in the case of an L-shaped drain pipe with an elbow, etc., the left and right divided bodies are swung open to sandwich the L-shaped drain pipe. It becomes possible to attach it.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a configuration of a first embodiment of a drain pipe mounting structure according to the present invention. As can be seen from FIG. 1, the drain pipe mounting structure 1 comprises a wall surface fixing portion 11 and a cylindrical body portion 12 fixed to the outer wall surface of the figure, and the cylindrical body portion 12 is provided in the water collecting tank 2. A rubber packing 13 for preventing jumping water is provided at the end of the drainage pipe insertion hole 21. Further, a screw hole 111 is formed in the wall surface fixing portion 11, and the drainage pipe mounting structure 1 is firmly fixed to a wall surface outside the figure by a screw inserted through the screw hole 111.

  As shown in FIG. 1, the water splash preventing rubber packing 13 is composed of a continuous body of triangular packing 131 formed by cutting radially from the substantially central portion of the rubber packing toward the circumferential direction. A substantially central portion is a free hole 14 through which the drain pipe 3 is inserted.

  FIG. 2 is a partial cross-sectional side view showing a state in which the drain pipe mounting structure 1 is fixed to the wall surface W with fixing screws B. FIG. The drainage pipe 3 protruding from the wall surface W passes through the inside of the cylindrical body part 12 and penetrates through the free hole 14, and the tip part thereof enters a drainage pipe insertion hole 21 provided in the water collecting trough 2 shown in FIG. Inserted. At this time, even if the thickness of the drainage pipe 3 varies depending on the construction conditions, the triangular packing 131 freely follows and covers the drainage pipe 3, and the rebounding of drainage from the gap between the drainage pipe 3 and the drainage pipe insertion hole 21 Prevents splashing water, etc., from splashing around and contaminating the wall W or the like.

  Fig.3 (a) is a front view which shows 2nd Embodiment of the attachment structure of the drain pipe concerning this invention. As shown in FIG. 3 (a), the drain pipe mounting structure 4 according to the second embodiment has the wall surface fixing portion 11, the cylindrical body portion 12, and the water splash preventing rubber packing 13 shown in FIG. The left divided body 41 and the right divided body 42 are made swingable around a fulcrum 43 provided at the upper part of the wall surface fixing portion. FIG. 3B is a front view showing a state in which the left divided body 41 and the right divided body 42 are swung open. By doing in this way, when it is difficult to attach using the drainage pipe attachment structure 1 of the first embodiment, as in the case of an L-shaped drainage pipe or the like with an elbow connected to the drainage pipe 3, As shown in FIG. 3B, the left and right divided bodies 41 and 42 can be opened and attached with good workability so as to sandwich the L-shaped drain pipe.

It is a perspective view which shows the structure of the attachment structure of the drain pipe concerning 1st Embodiment of this invention. It is a fragmentary sectional side view which shows the state which screw-fixed the attachment structure of the drain pipe concerning the said 1st Embodiment to the wall surface. (A) It is a front view which shows the attachment structure of the drain pipe concerning 2nd Embodiment of this invention. (B) It is a front view which shows the state which opened the attachment structure of the drain pipe concerning the said 2nd Embodiment to right and left.
