Description

  The present invention relates to a saddle piping system.

  Conventionally, it has been common to provide eaves so that rainwater that falls on the roof does not drip from the eaves.

  In order to prevent the rainwater collected by the eaves from splashing around, a eave is connected to the eaves through a funnel and the rainwater is guided to the vicinity of the ground by the eaves.

  By the way, it is known that this eaves bowl expands and contracts in the extending direction when the temperature changes due to solar radiation.

  Therefore, in general, the eaves must have a separate structure for absorbing the expansion and contraction.

  In order to solve this problem, Patent Document 1 discloses an eaves connection member in which an eaves connection portion, a stop, and a drainage connection portion are integrally formed.

  According to the configuration of Patent Document 1, it is possible to provide a gutter piping system in which the gutter connecting member can absorb the expansion and contraction of the eaves gutter.

On the other hand, Patent Document 2 discloses an invention in which the wastewater treatment amount is increased by a siphon drainage system including a bottomed cylindrical body that receives rainwater in order to reduce the tube diameter in consideration of cost and appearance.

  However, in patent document 1, since the thing with little conventional wastewater treatment amount is used as a soot, the diameter may become thick and the external appearance may worsen. Moreover, in patent document 2, since it is the structure connected to the bottom face of an eaves wall, after forming an opening in an eaves wall, it installs dust removal drains, an eaves, etc. There was a problem that it was necessary and time-consuming to install.

  Then, an object of this invention is to provide the dredging piping system which is easy to install and improves the appearance of appearance.

  In order to achieve the above object, the dredging piping system of the present invention includes an eaves eaves attached along the eaves of a building, a eaves for draining rainwater collected by the eaves eaves, and the eaves eaves and the eaves. The eaves pipe connecting system for connecting the eaves eaves, the eaves connection member provided at the end of the eave eaves in the extending direction and connected to the eaves eaves And a stop wall portion that closes the downstream end of the eaves and a eaves connection hole connected to the eaves, and a siphon device is provided under the eaves And

  Further, the siphon device of the dredging includes a main body pipe that guides rainwater to the vicinity of the ground, a drain pipe cover that connects a lower end of the main body pipe and a drain pipe buried in the ground, and the drain pipe A bottomed cylindrical body provided in a cover, having a top opening for receiving rainwater flowing out from a lower end opening of the main body conduit and sealing the lower end opening by the received rainwater, and the main body The lower end of the pipe line is inserted below the upper edge of the bottomed cylindrical body.

  Thus, the eaves piping system of the present invention, eaves eaves connection portion connected to the eaves eaves, a stop wall portion closing the downstream end of the eaves eaves, a eaves connection hole portion connected to the eaves, And a siphon device is provided at the bottom of the heel.

  Therefore, the saddle coupling member has two functions of a stop and a funnel, so that the number of parts is reduced and the connection structure is provided in advance so that the installation becomes easy.

  In addition, the siphon device increases the wastewater treatment capacity of the soot, so that a soot with a small diameter can be used, and the appearance of the soot improves.

  Then, by connecting the kite to the kite coupling member located at the downstream end of the eaves kite, the momentum of the rainwater flowing into the siphon device is increased, and the siphon phenomenon is likely to occur.

  Moreover, since the siphon device can be formed without providing a special structure in the main body conduit by providing the bottomed cylindrical body into which the lower end of the main body conduit is inserted as the siphon device, the appearance is improved. At the same time, it becomes a highly versatile siphon device.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  First, the whole structure of the culvert piping system S is demonstrated using FIG. The eaves piping system S includes an eave eave 2, a eaves 3 that drains rainwater collected by the eave eave 2, and a eaves connection member 4 that connects the eaves eaves 2 and 3.

  The eaves 2 is made of a synthetic resin such as vinyl chloride resin, for example, and includes a bottom plate 23 and side walls 24 and 25 as shown in FIG. 1. As shown in FIG. Is attached to the eaves rod support 49 attached to the eaves tip 13 using screws 491.

  As shown in FIG. 1, the end portion 21 of the eaves rod 2 is formed in a shape that fits into the eaves rod connection portion 41 of the rod connection member 4, and the side wall 24 is formed by the pressing piece 461 and the side wall portion 44. Is sandwiched, the bottom plate 23 is sandwiched between the presser piece 462 and the bottom plate portion 48, and the side wall 25 is sandwiched between the presser piece 463 and the side wall portion 45, whereby the eave basket 2 and the eaves connecting member 4 are fixed. .

  Moreover, in the dredge piping system S of this Embodiment, as shown in FIG. 2, the siphon apparatus 31 is provided in the lower part of the dredge 3. As shown in FIG.

  The siphon device 31 is a drain that connects a main body pipe (corresponding to a dredge in this case) 311 that guides rainwater to the vicinity of the ground, and a lower end of the main pipe and a drain pipe 313 embedded in the ground. A tube cover 315, and a bottomed tube provided in the drain tube cover 315, having a top opening for receiving rainwater flowing out from the lower end opening 311a of the main body conduit 311 and sealing the lower end opening 311a by the received rainwater And a body 312.

  The main body pipe line 311 is made of a synthetic resin such as vinyl chloride resin like the eaves rod 2, and the upper end 311 b is connected to the rod connection hole 43 of the rod connection member 4 as shown in FIG. 2. While being connected, the lower end portion is inserted into the bottomed cylindrical body 312.

  And the lower end opening 311a of the main body pipe line 311 is positioned below the upper edge 312a of the bottomed cylindrical body 312 so that the lower end opening 311a is closed in a state where the bottomed cylindrical body 312 is full of water, It is formed so that water is stored inside the main body conduit 311.

  The bottomed cylindrical body 312 is a cylindrical body made of a synthetic resin such as vinyl chloride resin, and four arms 312b,... Extending in the horizontal direction are provided on the upper edge 312a. ,... Are hooked on the cover portion 315 by projecting outward from the inner surface of the annular projection 315a provided on the inner peripheral surface of the drain pipe cover 315.

  A predetermined gap is provided between the inner side surface of the protrusion 315a and the outer peripheral surface of the bottomed cylindrical body 312 so that rainwater overflowing from the upper end of the bottomed cylindrical body 312 passes through the clearance to the lower drainage pipe. 313 is drained.

  Since the inner diameter of the drain pipe 313 is larger than the outer diameter of the bottomed cylindrical body 312, rainwater overflowing from the bottomed cylindrical body 312 can be smoothly drained.

  The drain pipe cover 315 has a cylindrical shape made of synthetic resin, and its upper opening is closed by a disc-shaped lid 314. A circular hole 314a having substantially the same diameter as the outer diameter of the main body pipe line 311 is provided at substantially the center of the lid 314, and the lower part of the main body pipe line 311 is inserted into the hole 314a in a watertight manner. Yes.

  As shown in FIG. 1, the eaves connecting member 4 of the present embodiment is a cylindrical member made of synthetic resin such as vinyl chloride resin, and is provided at an end portion 21 in the extending direction of the eaves eaves 2. The eaves connection part 41 connected to the eaves 2, the stop wall part 42 closing the downstream end of the eaves 2, the eaves connection hole 43 connected to the eaves 3, the side wall 24 of the eaves 2, 25, side wall portions 44 and 45 located on the extension of 25.

  A presser piece (461, 462, 463) having a substantially U-shaped cross-section is integrally provided on the eaves bowl connecting portion 41 so that the end portion 21 of the eaves bowl 2 can be fitted. And the locking piece 471,472 is provided in the upper edge of the side wall parts 44,45.

  Next, the effect | action of the vertical piping system S of this Embodiment is demonstrated.

  Since the dredging system S of the present invention is configured as shown in FIGS. 1 and 2, when it rains, it first receives rainwater from the roof 12, and this rainwater flows down to the vicinity of the eaves 13 by the gradient of the roof 12. Then, the rainwater that has flowed down flows into the eaves 2 from the tip of the roof 12 near the eaves 13, and the rainwater that has flowed down flows to the eaves connecting member 4 according to the gradient in the extending direction of the eaves 2.

  The rainwater that has flowed down to the hook connection member 4 is blocked by the stop wall portion 42 of the hook connection member 4 and stays there and flows into the hook connection hole 43 and directly flows into the hook connection hole 43. Then, it will be drained from the eaves 2.

  Next, rainwater drained from the eaves 2 through the eaves connection hole 43 to the eaves 3 flows down the main body conduit 311 of the eaves 3 and flows into the bottomed cylindrical body 312 from the lower end opening 311a. .

  Furthermore, since the rainwater that has flowed into the bottomed cylindrical body 312 is stored in the bottomed cylindrical body 312, the water level of the bottomed cylindrical body 312 rises.

  Then, the rainwater that has overflowed to the upper edge 312 a of the bottomed cylindrical body 312 is drained to the drain pipe 313 through a gap between the inner surface of the protrusion 315 a and the outer peripheral surface of the bottomed cylindrical body 312.

  Here, when the flow rate flowing into the bottomed cylindrical body 312 is larger than the flow rate overflowing from the gap between the arms 312 b,... And the projection 315 a, the rainwater is stored in the main body conduit 311.

  And when the water level in the main body pipe line 311 rises and reaches a predetermined water level in the main body pipe line 311, a siphon phenomenon occurs due to the eaves bowl 2, the eaves connection hole 43 and the eaves 3. The drainage pipe 313 is drained vigorously.

  As described above, since the hook connecting member 4 has two functions of a stop function and a funnel function, the number of parts is reduced and installation is facilitated.

  That is, since the scissor connecting member 4 of the present embodiment has two functions of a stop member and a funnel member that have been provided separately from each other in the past, it is also considered that the number of supporting tools for mounting is reduced. The number of parts can be greatly reduced.

  And since the number of parts is greatly reduced, the part mounting work is also greatly reduced.

  In addition, by providing the siphon device 31, the drainage treatment capacity of the dredge 3 is improved, so that a predetermined amount of drainage can be secured even if a small diameter is used as the dredge 3, and the appearance of the appearance is improved. To do.

  Then, the hook 3 is connected to the hook connecting member 4 located at the downstream end of the eaves hook 2, so that the momentum of rainwater flowing into the siphon device 31 is increased, and the siphon phenomenon is likely to occur.

  That is, in the conventional funnel, the eaves cage 2 is connected to both sides, so that the flow of rainwater cancels each other and drains into the cage 3 in a depressurized state. In this embodiment, Since the eaves wall 2 is only connected to one side, the rainwater flow is not canceled and the water can be drained to the wall 3 vigorously.

  Then, the velocity head due to the flow is added, and the upstream head becomes larger, so that the siphon phenomenon is likely to occur.

  Moreover, the siphon device 31 can be formed without providing any special structure in the main body pipe line 311 by providing the bottomed cylindrical body 312 into which the lower end portion of the main body pipe line 311 is inserted as the siphon apparatus 31. Therefore, the appearance of the appearance is improved and the siphon device 31 having high versatility is obtained.

  Further, by using a bottomed cylindrical body 312 having a somewhat large inner diameter, the siphon device 31 is formed using the common bottomed cylindrical body 312 even for the main body pipe line 311 having various outer diameters. Therefore, the structure is highly versatile.

  The preferred embodiments and examples of the present invention have been described in detail with reference to the drawings, but the specific configuration is not limited to the embodiments or examples, and does not depart from the gist of the present invention. A degree of design change is included in the present invention.

  For example, a dust removal drain may be provided above the heel connection hole 43.
