Description

  The present invention relates to an installation structure for a chain rod.

  Conventionally, a leash for flowing rainwater is installed in a building to prevent bending by attaching a weight to the lower end without grounding it and hanging it from the eaves. The rainwater to be spilled from the lower end of the rainwater to the ground (see, for example, Patent Document 1). However, if there is a large amount of rainwater flowing down the chain, the ground near the chain will overflow with the rainwater that has flowed down. The rainwater that flows down along the chain is spilled on a wide area of the ground around the chain, and there is a problem that the rainwater overflows and gets dirty on the wide area around the chain.

  In addition, as a kite for flowing rainwater, a kite in which a straight tubular kite member is fixed to a building wall is also known. Even when rainwater that has flowed down the dredging drips down on the ground, there is a problem that the ground overflows with rainwater that has flowed down. It is a common practice to connect the pipe to a pipe and drain the rainwater that has flowed down to the drainage path without any delay.

  The drainage structure to the drainage pipe in such dredging is effective in solving the problem that the ground overflows with rainwater that has flowed down, and it is conceivable to apply this technology when installing the leash. The current situation is that diversion to chain chains has not been realized due to the following problems.

In other words, unlike the above fence, the chain fence is not fixed to the building wall, and in order to hang it from the eaves so as not to bend, a weight is attached to the lower end so as not to contact the ground. There is a problem that this weight hinders connection to the drain pipe. In addition, a chain rod formed by connecting a plurality of chain piece members has a limit to an arbitrary length according to the construction site, unlike a rod formed of the above-mentioned straight tubular rod member, and fits in a drain pipe. There is also a problem that it is difficult to connect well.

  The present invention has been made in view of the above points, and the object of the present invention is to fit the drainage pipe so that it does not bend and to be connected to the drainage pipe, and to drain the rainwater flowing down along the chainfall It is an object of the present invention to provide an installation structure for a chain rod that can be drained.

In order to solve the above-mentioned problem, in the installation structure of the chain rod, it is the installation structure of the chain rod 1 that drains the rain water flowing down the chain rod 1 to the drain pipe 15 protruding from the ground, and the drain pipe 15 A cylindrical drain pipe cover 13 having a lower portion inserted therein is provided, the chain rod 1 is composed of a plurality of cylindrical chain piece members 5, and is fitted into the lower end portion and the upper end portion of the chain piece member 5. , 8, and the fitting cylinder portions 7, 8 are fitted to connect the chain piece members 5 adjacent to each other in the vertical direction, and a window formed by an opening 6 a on the cylinder side surface 5 a of each chain piece member 5. A portion 6 is provided, and at the position above the window portion 6 inside the chain piece member 5, a throttle portion 9 is provided for collecting and flowing rainwater flowing inside the chain piece member 5 ; The fitting tube portion of the lower end portion of the chain piece member 5 located at the lower end Is used for the connecting portion 1a at the lower end of the chain rod 1, and the connecting portion 1a is fitted to the upper portion of the drain pipe cover 13, and the fitting depth of the drain pipe cover 13 is adjusted by adjusting the fitting depth. The upper part and the connection part 1a are attached.

  According to this, by providing the cylindrical connecting portion 1a at the lower end portion of the chain rod 1, the connecting portion 1a is connected to the upper end of the cylindrical drain tube cover 13 connected to the drain tube 15 with a fitting structure. It is possible to connect the chain rod 1 and the drain pipe 15 and drain the rainwater flowing down through the chain rod 1 to the drain pipe 15 without stagnation. Since the connection with the tube cover 13 by the fitting structure involves attachment by adjusting the fitting depth, the chain rod 1 is pulled downward by the drain tube cover 13 attached to the connecting portion 1a. It can be prevented from bending. In other words, the chain 1 is not bent and fits well in the drain pipe 15 so that the rainwater flowing down to the chain 1 can be drained to the drainage route without delay, so that the ground around the chain 1 flows down. We were able to solve the problem of getting dirty with rainwater.

In addition, the engraved a threaded portion 10, 16 respectively the upper and the said connecting portion 1a of the chain of ornamental cups hanging from a gutter 1 of the drain pipe cover 13, the said drain pipe cover 13 by fastening the threaded portion 10 and 16 to each other chain of ornamental cups hanging from a gutter 1 and the mounting Rukoto preferably detachably a. According to this, it is possible to adjust the fitting depth between the drain pipe cover 13 and the connecting portion 1a of the chain rod 1 by a simple screw fastening structure with the screw portions 10 and 16, and the drain pipe cover 13 and the chain rod. The connecting portion 1a can be detachably attached, and the drain pipe cover 13 and the chain rod 1 can be easily removed at the time of maintenance or the like.

Further, it is preferable to fix the said drainage pipe 15 and the water discharge pipe cover 13. According to this, the lower end of the chain 1 attached to the drain pipe cover 13 fixed to the drain pipe 15 is in a fixed state, and the effect of preventing the shake of the chain 1 that is beaten by wind can be improved.

  The present invention has the advantage that the rainwater flowing down along the chain can be drained to the drainage route without stagnation by being connected to the drain pipe well so as not to bend the chain.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The chain fence 1 of this example constitutes a part of the fence 3 installed along the building wall 2 as shown in FIG. In other words, the cage 3 is composed of a straight tubular collar 4 whose upper region is fixed to the building wall 2 via the cage support 14, and whose lower region is a chain suspended from the straight tubular collar 4. It consists of 樋 1. The lower end of the chain rod 1 is connected to a drain pipe 15 projecting from the ground directly below the chain rod 1, and rainwater flowing down the chain rod 1 can be drained to the drainage path through the drain pipe 15. . Specifically, a cylindrical drain pipe cover 13 having a lower portion inserted into the drain pipe 15 is provided, and a cylindrical connecting portion 1a provided at the lower end of the chain rod 1 is fitted to the upper part of the drain pipe cover 13, At this time, the fitting depth is adjusted to attach the upper portion of the drain pipe cover 13 and the connecting portion 1a of the chain rod 1 so that the chain rod 1 is not bent and is connected to the drain pipe 15 and connected well. Has been made possible.

  Here, the chain rod 1 of this example is suspended and supported by vertically connecting a plurality of chain piece members 5 as shown in FIG. As shown in FIG. 2, the chain piece member 5 is formed in a cylindrical shape that can be opened up and down. The upper end portion of the cylindrical chain piece member 5 constitutes an upper fitting cylinder portion 7. Further, a lower fitting cylinder portion 8 is provided at the lower end of the chain piece member 5 so as to be fitted into the upper fitting cylinder portion 7 of the lower chain piece member 5 to connect the upper and lower chain piece members 5 in a straight tube shape. It has been. The lower fitting cylinder portion 8 has an outer diameter of the upper fitting cylinder portion 7 in order to fit into the upper fitting cylinder portion 7 in order to prevent leakage of rainwater flowing down inside the chain piece member 5. The small diameter portion is made smaller in diameter so as to be substantially the same as the inner diameter. That is, the chain rod 1 of this example is formed by connecting the chain piece members 5 so that they hardly move by the fitting structure of the upper fitting cylinder portion 7 and the lower fitting cylinder portion 8. The effect of suppressing wobbling of the beaten chains 1 is improved.

  Specifically, since the lower chain piece member 5 is suspended and supported by the upper chain piece member 5, a drop-off preventing structure is provided between the upper fitting cylinder portion 7 and the lower fitting cylinder portion 8. In this example, a screw fastening structure is employed as a drop-off prevention structure. That is, the screw part 10 is carved in the upper fitting cylinder part 7 and the lower fitting cylinder part 8, and the upper and lower chain piece members 5 are detachably connected by fastening the screw parts 10 together. Specifically, the screw portion 10 of the upper fitting tube portion 7 is a female screw portion 10a engraved on the inner surface, and the screw portion 10 of the lower fitting tube portion 8 is a male screw portion 10b engraved on the outer surface. Thus, when the lower fitting cylinder portion 8 is inserted into the upper fitting cylinder portion 7, the chain piece member 5 is rotated around the axis, so that the upper fitting is performed as shown in FIG. The male threaded portion 10b of the lower fitting tube portion 8 is screwed into the female threaded portion 10a of the tubular portion 7, and the lower chain piece member 5 is detachably supported so as not to fall out of the upper chain piece member 5. ing. When the chain piece member 5 is detachably connected, the chain piece member 5 can be removed during maintenance of the chain rod 1 or the like, which is convenient.

  In addition, the cylindrical chain piece member 5 has rainwater flowing down through the inside thereof, but a window portion 6 for enjoying the rainwater flowing down like a general chain rod 1 from the outside. Is provided. This window portion 6 is provided at an upper position adjacent to the lower fitting tube portion 8 of the chain piece member 5 and has an opening 6a opened on the side surface of the tube leaving four standing rib portions 11 at equal intervals in the circumferential direction. It is constituted by. Here, at the upper position adjacent to the window portion 6 inside the chain piece member 5, a throttle portion 9 is provided inside the chain piece member 5 for collecting and flowing rainwater flowing inside. The throttle portion 9 is constituted by a throttle cylinder portion that is formed inwardly so as to reduce the inner diameter from the cylindrical side surface of the chain piece member 5, and the throttle cylinder portion is a cylindrical side surface of the cylindrical chain piece member 5. The outer side is covered with 5a so that it does not appear on the outer appearance of the chain 1. In addition, the standing rib part 11 is hung down from the cylinder side surface 5a of the cylindrical chain piece member 5 which is the site | part which covers the outer side of the said aperture | striction cylinder part. According to this, rainwater that can be seen from the window portion 6 flows down the central portion of the cylindrical chain piece member 5 by the throttle portion 9, and this rainwater passes through the window portion 6 from the inside of the chain piece member 5. It avoids the fear of splashing outward.

  As described above, the chain rod 1 of the present example is connected to the drain pipe 15 by connecting the lower end portion thereof to the drain pipe cover 13 provided on the drain pipe 15. The drain pipe cover 13 is connected to the drain pipe 15 as shown in FIG. In this way, the tube material is formed in a circular tube shape that opens up and down. Specifically, the drain pipe cover 13 has a cylindrical main cylinder portion 17 having a threaded portion 16 (female screw portion) engraved on the inner surface, and the lower diameter of the main cylinder portion 17 is slightly reduced to a small diameter. When the inner cylinder part 18 is formed, an outer cylinder part 19 that protrudes outward from the upper end of the inner cylinder part 18 and goes around the inner cylinder part 18 with a gap is formed. The drain pipe cover 13 is inserted into the gap between the inner cylinder part 18 and the outer cylinder part 19 by inserting the upper part of the circular drain pipe 15 into the drain pipe 15, so that the drain pipe 15 is inserted into the drain pipe 15. It is installed.

  To connect the lower end portion of the chain rod 1 to the upper portion of the cylindrical drain pipe cover 13, it is possible to provide the cylindrical connection portion 1 a at the lower end portion of the chain rod 1. That is, even if the chain rod 1 has an arbitrary shape, the connection portion 1a is connected to the upper portion of the cylindrical drain pipe cover 13 with a fitting structure by providing the cylindrical connection portion 1a at the lower end portion of the chain rod 1. It can be done. In addition, in the chain rod 1 of this example configured by the circular chain piece member 5, the cylindrical connecting portion 1a is configured by the lower fitting tube portion 8 of the chain piece member 5 at the lowest position of the chain rod 1. The chain rod 1 is connected to the drain pipe cover 13 by a fitting structure in which the lower fitting cylinder part 8 is fitted into the main cylinder part 17 of the drain pipe cover 13.

  Normally, a weight is hung from the lower end of the chain 1 that is not fixed to the building wall 2 so as not to bend. However, if the connecting portion 1a is provided at the lower end as described above, the weight is provided. Therefore, there is a risk that the chain 1 will bend. However, in this example, this fear is eliminated by attaching the chain rod 1 to the drain pipe cover 13 which is relatively large and heavy. In addition, when attaching the chain rod 1 to the drain pipe cover 13, it is necessary to adjust the attachment position to the drain pipe cover 13 to the lower end position of the chain rod 1 which is different for each installation site. Between the drain pipe cover 13 of the example and the chain rod 1, an attaching means for adjusting the fitting depth and attaching the both is provided.

  As the attachment means for adjusting the fitting depth, a screw fastening structure is employed in this example. That is, the attachment means of this example includes a screw portion 16 (female screw portion) engraved on the inner surface of the main cylinder portion 17 of the drain pipe cover 13 and a screw portion 10 (engraved on the outer surface of the lower fitting cylinder portion 8). Male screw portion 10b). These threaded portions 10 and 16 can be screwed freely, and the fitting depth can be adjusted to attach the chain rod 1 and the drain pipe cover 13. As a result, the drainage pipe cover 13 attached to the connecting portion 1a through the attachment means can pull the chain rod 1 downward so as not to bend, that is, drain the drainage without bending the chain rod 1. The rainwater flowing down to the chain 1 can be drained into the drainage path of the drainage pipe 15 without being delayed, and the ground around the chain 1 is contaminated with the rainwater flowing down. Was able to solve the problem.

  Here, the screw fastening structure employed in the attachment means of the present example makes the drain pipe cover 13 and the chain rod 1 detachable. Therefore, there is an advantage that the drain pipe cover 13 and the chain rod 1 can be easily removed at the time of maintenance or the like, which is convenient. Further, this attachment means is a screw fastening structure that uses a structure for preventing the drop-off between the chain piece members 5 and has the advantage that the structure can be simplified and the structure can be simplified. Yes. Thus, in this example, since the lower end of the chain rod 1 supported by suspension is connected to the drain pipe 15, the lower end of the chain rod 1 is regulated by the drain pipe 15 and the drain pipe cover 13 even if not fixed. Improvement of the suppression effect of the shake of the heel 1 is achieved. Of course, the drain pipe cover 13 may be fixed to the drain pipe 15 with an adhesive or the like, and according to this, it is possible to further improve the effect of suppressing the fluctuation of the chain rod 1.

  By the way, the leash 1 having the above structure may be suspended from the eaves like the general leash 1 and disposed in the building. In this example, the leash 1 is provided along the building wall 2 as shown in FIG. Part of the kite 3 is made up. Since the chain rod 1 is not fixed to the building wall 2 through the rod support 14 like the ordinary rod 3 (the rod 3 composed of the straight tubular rod portion 4 extending vertically), the chain rod The heel 1 cannot be climbed to reach the heel support 14 with a hand or foot like the ordinary heel 3, and has an advantage in crime prevention compared to the general heel 3. . In other words, the bag 3 (FIG. 1 (a)) of the present example in which the lower region is composed of the chain rod 1 can effectively exhibit the security advantage of the chain rod 1. Here, since the chain 1 is not fixed to the building wall 2 as described above, it easily swings when it is blown by the wind, and when it is installed along the building wall 2, it may collide with the building wall 2. However, the chain rod 1 of the present example is such that the chain piece members 5 are connected with each other in a fitting structure as described above, or the lower end is attached to the drain pipe cover 13 provided on the drain pipe 15. The device for preventing the swinging has been devised to reduce the possibility of hitting the building wall 2 when it is blown by the wind, so that the chain 1 can be installed along the building wall 2 without any trouble. Further, in the cage 3 of the present example, the upper region is constituted by the straight tubular collar portion 4 fixed to the building wall 2, and the lower region is constituted by the chain rod 1 suspended from the straight tubular collar portion 4. It is configured. The chain rod 1 constituting the lower region of the rod 3 has a sufficiently short length compared to the chain rod 1 suspended from the eaves, and its runout width even when blown by the wind In this respect as well, the effect of suppressing the vibration of the chain 1 blown by the wind is improved, and the risk of the chain 1 hitting the building wall 2 is reduced.

  Moreover, the chain rod 1 of this example which constitutes a part of the rod 3 so as to be suspended from the straight tubular rod portion 4 is formed by connecting the cylindrical chain piece members 5 as described above. The appearance of the bowl 3 appears as if the circular tube is continuous. Here, the outer diameter dimension of the cylindrical chain piece member 5 of the present example is formed substantially the same as the outer diameter dimension of the cylindrical straight tubular collar portion 4 that supports the chain collar 1 in a suspended manner. The upper part is composed of the straight tubular collar part 4 and the lower part is composed of the chain collar 1 and the collar 3 of this example has a sense of unity such that the circular pipes are continuous as shown in FIG. A good appearance is to appear.

  Here, the chain rod 1 is attached to the straight tubular collar portion 4 via a cylindrical coupling joint 12. The cylindrical coupling joint 12 is provided with an upper fitting cylinder (not shown) at the upper end thereof, and the upper fitting cylinder 4 is fitted to the lower end of the straight tubular collar 4 so that the straight tubular collar 4 is fitted. It is attached to the underside. In this example, in order to reveal the continuity of the appearance by the straight tubular collar 4 and the chain collar 1 having substantially the same diameter, the upper fitting cylindrical portion of the coupling joint 12 is fitted into the lower end of the straight tubular collar 4, A waterproofing treatment such as packing is applied and bonded with an adhesive. Note that the height position of the lower end of the straight tubular collar 4 from the ground differs depending on the configuration length of the chain collar 1, and this is dealt with by cutting the straight tubular collar 4 at an arbitrary length position. However, since the cut surface of the straight tubular collar 4 is circular and constant regardless of the arbitrary length position, the upper fitting cylinder part is also formed at the lower end of the straight tubular collar 4 having an arbitrary length. It is possible to make it fit securely.

  Further, a lower end portion of the cylindrical coupling joint 12 is provided with a leash attaching portion (not shown) for attaching the upper end of the leash 1. The chain hook attaching portion of this example is formed in a cylindrical shape, and is fitted into the upper fitting cylinder portion 7 of the uppermost chain piece member 5 of the chain rod 1 so as to be connectable. A chain rod 1 is attached to the lower side of 12. In addition, since the leash 1 is suspended and supported by the connecting joint 12, a drop-off preventing means is provided between the leash attaching portion of the connecting joint 12 and the upper end portion of the leash 1. In this example, this drop-off prevention means employs a structure that uses the above-described drop-off prevention structure between the chain piece members 5, that is, a screw fastening structure. That is, in this example, the upper fitting cylinder portion 7 of the chain piece member 5 constituting the upper end portion of the chain rod 1 is provided with a female thread portion 10a, and the chain thread mounting portion of the coupling joint 12 is connected to the female thread portion 10a. A male screw portion (not shown) to be screwed is provided. In this way, the connection structure (drop-off prevention structure) between the chain piece members 5 constituting the chain rod 1 is used for the connection structure (fall-off prevention means) of the chain rod 1 and the connection joint 12, so that the member can also be used. Thus, the configuration is simplified.
