Description

  The present invention relates to a temporary toilet pipe joint capable of connecting a standing pipe embedded in the ground and a temporary toilet.

  2. Description of the Related Art Conventionally, a temporary toilet that is connectable to a vertical pipe (for example, an outdoor manhole or an upright vertical pipe) embedded in the ground in advance is known. By installing a temporary toilet above the standing pipe buried in the ground and connecting the temporary toilet to the standing pipe, the existing standing pipe can be used as a sewage pipe for the temporary toilet. Thereby, in the event of a disaster, a temporary toilet can be installed by diverting existing standing pipes.

  For example, Patent Document 1 discloses a temporary toilet that is used by being connected to an outdoor manhole when a toilet cannot be used due to a disaster such as an earthquake. The temporary toilet disclosed in Patent Document 1 has an advantage that the configuration is simple, the size is small, and the weight is light. However, the temporary toilet disclosed in Patent Document 1 does not incorporate a deodorizing valve. Therefore, there is a problem that odor leaks to the outside.

  Patent Document 2 discloses a temporary toilet with a built-in deodorant valve. In a temporary toilet with a built-in deodorizing valve, odor can be prevented from leaking. However, since the deodorizing valve is built in, the configuration becomes complicated. In addition, it tends to increase in size and weight.

  As described above, a temporary toilet without a deodorizing valve and a temporary toilet with a deodorizing valve have advantages and disadvantages, and both temporary toilets are in demand. Which temporary toilet will be installed at the time of a disaster is case by case. Therefore, it is not possible to specify in advance which temporary toilet will be used in the future when burying the pipe in the ground. Therefore, it is desirable to prepare both temporary toilets so that they can be used during the construction of the standpipe.

  The present invention has been made in view of such a point, and the purpose thereof is to use a standing pipe buried in the ground as a sewage pipe of either a temporary toilet with a built-in deodorizing valve or a temporary toilet without a built-in deodorizing valve. It is to provide a temporary toilet pipe joint that can be used.

  A pipe joint for a temporary toilet according to the present invention connects a pipe provided with a standing pipe embedded in the ground and a lid frame fitted to the standing pipe, and a temporary toilet installed above the pipe A temporary toilet pipe joint that includes a closing plate portion that is detachably supported by the lid frame, a cylindrical portion that penetrates the closing plate portion, and a deodorizing valve that is provided in the cylindrical portion. A connection port to which the temporary toilet can be connected is formed in the upper part of the cylindrical portion. The temporary toilet pipe joint is configured to be disposed below the lid when the lid is fitted into the lid frame.

  In the pipe joint for temporary toilets, a standing pipe is constructed, and after the lid frame is fitted to the standing pipe, the closing plate portion is supported by the lid frame. Then, the lid is fitted into the lid frame. Thereby, the pipe joint for temporary toilets is accommodated in the standing pipe. When installing a temporary toilet, such as during a disaster, remove the lid from the lid frame. When installing a temporary toilet that does not contain a deodorizing valve, connect the temporary toilet to the connection port of the tube. Thereby, it can prevent that an odor leaks, using the temporary toilet which does not incorporate a deodorizing valve. Here, “connecting a temporary toilet” includes both a case where the temporary toilet is directly connected and a case where the temporary toilet is connected indirectly using another member such as a pipe or a pipe joint. On the other hand, when installing a temporary toilet with a built-in deodorant valve, the temporary toilet pipe joint is removed from the lid frame. Then, a temporary toilet is installed above the lid frame and the standpipe. Since this temporary toilet has a built-in deodorizing valve, it is possible to prevent the odor from leaking in this case as well. Therefore, by using the temporary toilet pipe joint, the existing standing pipe buried in the ground can be used as a sewage pipe for either a temporary toilet incorporating a deodorizing valve or a temporary toilet not incorporating a deodorizing valve. be able to.

  According to a preferred aspect of the present invention, the lid frame includes a cylindrical portion, a lid fitting portion into which the lid is detachably fitted, and a radial direction from the cylindrical portion below the lid fitting portion. And an annular portion protruding inward. The closing plate portion is configured to be placed on the annular portion without being fixed to the lid frame when the lid is fitted into the lid frame.

  According to the above aspect, the temporary toilet pipe joint can be supported by the lid frame simply by placing the closing plate portion on the annular portion of the lid frame. The temporary toilet pipe joint can be easily attached to and detached from the lid frame. Therefore, the temporary toilet pipe joint can be easily installed at the time of construction of the standing pipe as compared with the case where the temporary toilet pipe joint is detachably fixed to the lid frame with a bolt or the like. Moreover, when installing the temporary toilet which incorporates a deodorizing valve, the pipe joint for temporary toilets can be easily removed from a cover frame, and a temporary toilet can be installed easily.

  According to a preferred aspect of the present invention, at least the closing plate portion and the cylindrical portion are made of synthetic resin. The temporary toilet pipe joint includes a weight.

  According to the above aspect, the weight between the closing plate portion and the annular portion of the lid frame is enhanced by the weight. Therefore, it can prevent more reliably that an odor leaks from the clearance gap between a closing board part and the cyclic | annular part of a lid frame.

  According to a preferred aspect of the present invention, the temporary toilet pipe joint includes a seal member provided at a peripheral edge portion of the lower surface of the closing plate portion.

  According to the said aspect, the adhesiveness between the closing board part and the cyclic | annular part of a cover frame increases with the said sealing member. Therefore, it can prevent more reliably that an odor leaks from the clearance gap between a closing board part and the cyclic | annular part of a lid frame.

  According to a preferred aspect of the present invention, the temporary toilet pipe joint includes a string-like member attachment portion to which a string-like member connected to the lid is attached.

  According to the said aspect, a lid | cover and the pipe joint for temporary toilets can be connected with a string-like member. During the period of use of the temporary toilet, the lid remains removed from the lid frame. However, since the lid is connected to the temporary toilet pipe joint by the string-like member, it is possible to prevent the lid from being lost.

  According to the present invention, there is provided a pipe joint for a temporary toilet in which a standing pipe embedded in the ground can be used as either a sewage pipe of a temporary toilet with a built-in deodorizing valve or a temporary toilet without a built-in deodorizing valve. be able to.

It is a side view of the pipe joint for temporary toilets concerning one embodiment of the present invention. It is a top view of the pipe joint for temporary toilets. It is a bottom view of the said temporary toilet pipe joint. It is a longitudinal cross-sectional view when the said pipe joint for temporary toilets is accommodated in the inside of a standing pipe. It is a longitudinal cross-sectional view when the said pipe joint for temporary toilets is connected to the temporary toilet. It is a figure which shows the state which installed the temporary toilet which does not incorporate a deodorizing valve. It is a figure which shows the state which installed the temporary toilet which incorporates a deodorizing valve.

  Hereinafter, an embodiment of a temporary toilet pipe joint (hereinafter referred to as a pipe joint) according to the present invention will be described with reference to the drawings. FIG. 1 is a side view of the pipe joint 1. FIG. 2 is a plan view of the pipe joint 1. FIG. 3 is a bottom view of the pipe joint 1. FIG. 4 is a longitudinal cross-sectional view when the pipe joint 1 is accommodated in the standing pipe 7 embedded in the ground.

  As shown in FIGS. 1 to 3, the pipe joint 1 includes a closing plate portion 2, a cylindrical portion 3 penetrating the closing plate portion 2, and a deodorizing valve 4 provided in the cylindrical portion 3.

  The shape of the closing plate portion 2 is not particularly limited, but is formed in a disc shape in the present embodiment. An annular seal member 5 is attached to the peripheral edge of the lower surface of the closing plate portion 2 (see FIG. 3). Although the material of the sealing member 5 is not specifically limited, For example, it is rubber. As the seal member 5, for example, a rubber seal ring can be used.

  Although the shape of the cylinder part 3 is not specifically limited, In this embodiment, it is formed in the cylindrical shape. A connection port 3 a made up of a receiving port is formed in the upper part of the cylindrical portion 3. However, the connection port 3a is not limited to the receiving port, and may be a connecting port. The shape of the cylindrical portion 3 is not limited to a cylindrical shape.

  Although the closing plate part 2 and the cylinder part 3 may be separate bodies, they may be integrally formed. In this embodiment, the closing plate part 2 and the cylinder part 3 are integrally formed. Although the material of the closing plate part 2 and the cylinder part 3 is not specifically limited, In this embodiment, it is a product made from a synthetic resin.

  The deodorizing valve 4 includes an arm 4a extending downward from the closing plate portion 2, a valve body 4b, a support shaft 4c that supports the valve body 4b to be swingable on the arm 4a, and a weight 4d. The arm 4 a is formed in an L shape and is fixed to the closing plate portion 2 with a bolt 15. However, the fixing method of the arm 4a with respect to the closing plate part 2 is not limited at all. As shown in FIG. 3, the weight 4d is connected to the valve body 4b. The weight 4d may be a separate body from the valve body 4b, or may be integrally formed with the valve body 4b. In this embodiment, the weight 4d is integrally formed with the valve body 4b. As shown in FIG. 3, the weight 4d is disposed on the opposite side of the valve body 4b with respect to the axis 4f of the support shaft 4c. In FIG. 3, the valve body 4b is disposed on the right side of the axis 4f, and the weight 4d is disposed on the left side of the axis 4f. Since the weight of the weight 4d is larger than the weight of the valve body 4b, an upward force is applied to the valve body 4b around the axis 4f when no sewage is collected on the valve body 4b. Therefore, as shown in FIGS. 1 and 4, the valve body 4b is in a closed state. On the other hand, when sewage accumulates on the valve body 4b and the weight of the sewage and the valve body 4b becomes larger than the weight of the weight 4d, the valve body 4b rotates downward around the axis 4f. As a result, the valve body 4b is opened as shown in FIG.

  The valve body 4b is configured to open and close the lower opening of the cylindrical portion 3. A rubber ring 6 is attached to the lower end surface of the cylindrical portion 3 (see FIG. 5). When the valve body 4b is closed, the rubber ring 6 is interposed between the valve body 4b and the lower end surface of the cylindrical portion 3 (see FIG. 4). The rubber ring 6 improves the sealing performance when the valve body 4b is closed. However, the rubber ring 6 is not necessarily required and can be omitted. The rubber ring 6 may be attached to the valve body 4b. It is also possible to use a seal member other than the rubber ring 6.

  The above is the configuration of the pipe joint 1. The pipe joint 1 is a member that connects a pipe 10 including a standing pipe 7 buried in the ground and a lid frame 8 fitted to the standing pipe 7 and a temporary toilet installed above the pipe 10. However, as shown in FIG. 4, before the temporary toilet is installed, it is housed inside the standpipe 7.

  The vertical pipe 7 is a pipe extending in the vertical direction and buried in the ground. The vertical pipe 7 is, for example, a manhole, a vertical pipe, or the like. Although illustration is omitted, the lower end portion of the vertical pipe 7 is connected to a manhole, a sewage pipe, or a sewage pipe connected to the sewage main pipe. The material of the vertical pipe 7 is not limited at all, and is concrete, synthetic resin, or the like, for example.

  As shown in FIG. 4, the lid frame 8 includes a cylindrical portion 8a, a lid fitting portion 8b into which the lid 11 is detachably fitted, and a radially inner side from the cylindrical portion 8a below the lid fitting portion 8b. And an annular portion 8c protruding from the bottom.

  The pipe joint 1 and the lid 11 are connected by a chain 12. Here, an attachment portion 9 protruding upward is formed on the closing plate portion 2 of the pipe joint 1. A hole 9a is formed in the attachment portion 9, and one end portion of the chain 12 is engaged with the hole 9a. The lid 11 is formed with a mounting portion 11a protruding downward. The other end of the chain 12 is locked in the hole 11b of the attachment portion 11a. The chain 12 is an example of a string member. The string-like member is a long member that can be easily deformed. However, the string-like member is not limited to the chain 12 but may be a belt, a string, a wire, or the like. In the drawings other than FIG. 4, illustration of the attachment portion 9 and the chain 12 is omitted.

  As shown in FIG. 4, when the lid 11 is fitted into the lid frame 8, the pipe joint 1 is disposed below the lid 11. The pipe joint 1 is disposed at a position lower than the ground surface GL. The pipe joint 1 is accommodated inside the vertical pipe 7. The pipe joint 1 is detachably supported by the lid frame 8. Although the pipe joint 1 may be fixed to the lid frame 8 with screws or the like, in this embodiment, the pipe joint 1 is not fixed to the lid frame 8 and the closing plate portion 2 is an annular shape of the lid frame 8. It is supported by the lid frame 8 by being placed on the portion 8c. The pipe joint 1 can be easily attached to the lid frame 8 simply by placing the closing plate portion 2 on the annular portion 8 c of the lid frame 8. Conversely, the pipe joint 1 can be easily detached from the lid frame 8 simply by lifting the pipe joint 1.

  When the closing plate portion 2 is placed on the annular portion 8c, the seal member 5 is interposed between the closing plate portion 2 and the annular portion 8c. The seal member 5 closes the gap between the closing plate portion 2 and the annular portion 8c. The gap between the pipe joint 1 and the lid frame 8 is closed, and the sealing performance is kept good.

  As shown in FIG. 4, the closing plate portion 2 may be provided with a protrusion 2 a having an outer peripheral surface that contacts the inner peripheral surface of the annular portion 8 c of the lid frame 8. The closing plate portion 2 is in contact with the lower surface portion that contacts the upper surface of the annular portion 8c via the seal member 5 and the inner peripheral surface of the annular portion 8c (may be in direct contact, or contact via the seal member). A step portion having an outer peripheral surface may be provided.

  Since the pipe joint 1 can be accommodated in the vertical pipe 7, it can be installed together when the vertical pipe 7 is constructed. For example, after constructing the standpipe 7, the lid frame 8 is fitted into the upper end portion of the standpipe 7. Then, the pipe joint 1 is attached to the lid frame 8, and the lid 11 is fitted into the lid frame 8. Thereby, the pipe joint 1 can be accommodated in the inside of the standing pipe 7 in advance. By storing the pipe joint 1 in the vertical pipe 7 in advance, it is not necessary to bring the pipe joint 1 to the installation site when installing a temporary toilet in the event of a disaster.

  Next, an example of a method for installing a temporary toilet will be described. In the present embodiment, the pipe 10 can be connected to either a temporary toilet without a deodorizing valve or a temporary toilet with a deodorizing valve. In addition, the structure of a temporary toilet is not specifically limited.

  First, a method for connecting a temporary toilet without a deodorant valve will be described. When installing the temporary toilet, first, the lid 11 is removed from the lid frame 8. Next, as shown in FIG. 6, the temporary toilet 20 is installed above the lid frame 8 and the vertical pipe 7, and the temporary toilet 20 is connected to the connection port 3a of the pipe joint 1 (see FIG. 5). "Connecting the temporary toilet 20" includes both a case where the discharge portion of the temporary toilet 20 is directly connected and a case where it is indirectly connected via a pipe or a pipe joint.

  Although not shown in FIG. 6, the lid 11 is connected to the pipe joint 1 by a chain 12 (see FIG. 4). The lid 11 remains in the vicinity of the temporary toilet 20 while being connected to the chain 12. Therefore, it is possible to prevent the lid 11 from being lost after the temporary toilet 20 is installed. However, if the lid 11 is in the way, the chain 12 can be removed and the lid 11 can be moved to another location.

  Although the specific configuration of the temporary toilet 20 is not limited at all, the temporary toilet 20 according to the present embodiment includes a bowl 21 that constitutes a toilet, a water supply tank 22 that stores water, and a frame that supports the bowl 21 and the water supply tank 22. 23.

  The temporary toilet 20 that does not include a deodorizing valve has a simple configuration because it does not include the deodorizing valve. Moreover, there exists an advantage that size reduction and weight reduction are possible. However, the temporary toilet 20 itself cannot prevent the odor from leaking outside. However, according to this embodiment, since the pipe joint 1 including the deodorizing valve 4 is interposed between the temporary toilet 20 and the vertical pipe 7, it is possible to prevent odor from leaking to the outside.

  Next, a method for connecting a temporary toilet incorporating a deodorizing valve will be described. Also in this case, the lid 11 is first removed from the lid frame 8. Next, the pipe joint 1 is removed from the lid frame 8. As described above, in the present embodiment, the pipe joint 1 is merely placed on the annular portion 8 c of the lid frame 8, and therefore can be easily detached from the lid frame 8 simply by lifting the pipe joint 1. Next, as shown in FIG. 7, the temporary toilet 30 is installed above the lid frame 8 and the standpipe 7, and the temporary toilet 30 is connected to the lid frame 8 or the standpipe 7. Although the connection method of the temporary toilet 30 is not limited at all, in this embodiment, the connection member 40 in which the through hole 41 is formed is used. First, the connecting member 40 is fitted into the lid frame 8, and the discharge portion of the temporary toilet 30 is fitted into the through hole 41 of the connecting member 40. And the clearance gap between the discharge part and the through-hole 41 is filled up with a bonding agent. Thereby, the temporary toilet 30 and the standpipe 7 can be connected. The connecting member 40 may be a separate member from the lid 11, but the lid 11 may be used as the connecting member 40 by forming a through hole 41 in the lid 11.

  The specific configuration of the temporary toilet 30 is not limited in any way, but here the temporary toilet 30 includes a bowl 31 constituting a toilet bowl, a deodorizing valve 34 provided at a lower portion of the bowl 31, a water supply tank 32 for storing water, A frame 31 that supports the bowl 31 and the water supply tank 32 is provided.

  As described above, according to the present embodiment, an existing standing pipe buried in the ground is installed regardless of whether the temporary toilet 20 without a deodorizing valve or the temporary toilet 30 with a deodorizing valve is installed. 7 can be used as a sewage pipe for a temporary toilet. Therefore, in the construction stage of the standpipe 7, the standpipe 7 can be prepared so that it can be used for both temporary toilets 20 and 30.

  When installing the temporary toilet 20 which does not incorporate a deodorizing valve, it is possible to prepare a deodorizing valve separately from the temporary toilet 20, and attach a deodorizing valve by retrofit simultaneously with installation of the temporary toilet 20. However, according to this embodiment, since the pipe joint 1 is accommodated in the vertical pipe 7, when installing the temporary toilet 20 which does not incorporate a deodorizing valve at the time of a disaster etc., it is necessary to carry a deodorizing valve to the installation site. There is no. Therefore, the temporary toilet 20 which does not incorporate a deodorizing valve can be installed more easily. Further, the internal space of the vertical pipe 7 can be effectively used as a storage space for the pipe joint 1.

  The standpipe 7 is used as a sewage pipe for a temporary toilet when the temporary toilets 20 and 30 are installed, but is normally connected to the sewage main pipe (that is, before the temporary toilets 20 and 30 are installed). Used as a pipe for inspecting a manhole, masu or sewage pipe (not shown) from the ground. Since the pipe joint 1 according to this embodiment is detachable from the lid frame 8, it can be easily detached from the lid frame 8 at the time of inspection. Therefore, normal inspection is easy.

  According to the present embodiment, the pipe joint 1 is supported by the lid frame 8 by placing the closing plate portion 2 without being fixed to the annular portion 8 c of the lid frame 8. Therefore, the pipe joint 1 can be easily attached to the lid frame 8 simply by placing the closing plate portion 2 on the annular portion 8 c of the lid frame 8. According to the present embodiment, the pipe joint 1 can be easily attached to and detached from the lid frame 8. Therefore, the pipe joint 1 can be easily installed when the standing pipe 7 is constructed, and the pipe joint 1 can be easily detached from the lid frame 8 when installing the temporary toilet 30 incorporating the deodorizing valve. The temporary toilet 30 can be easily installed. Also, normal inspection is easy.

  By the way, in this embodiment, at least the closing plate part 2 and the cylinder part 3 of the pipe joint 1 are made of synthetic resin. Compared to the case where the closing plate portion 2 and the cylindrical portion 3 are made of metal, the pipe joint 1 is lighter. When the weight of the pipe joint 1 is small, the pressure between the closing plate portion 2 and the annular portion 8c of the lid frame 8 is relatively small, so that the sealing performance between the pipe joint 1 and the lid frame 8 is reduced. Odor may leak out. However, the pipe joint 1 according to the present embodiment includes the weight 4d. Therefore, the weight of the pipe joint 1 can be increased, and the adhesion between the closing plate portion 2 and the annular portion 8c of the lid frame 8 can be enhanced. Therefore, the sealing performance between the pipe joint 1 and the lid frame 8 can be enhanced, and odor can be more reliably prevented from leaking to the outside.

  Note that the weight 4d according to the present embodiment is originally a weight that applies a closing force to the valve body 4b of the deodorizing valve 4. The weight 4d opens the valve body 4b of the deodorizing valve 4 and discharges the sewage accumulated on the valve body 4b, and then the valve body 4b is automatically closed. According to this embodiment, the weight 4d for closing the valve body 4b can be used as a weight for improving the sealing performance.

  Moreover, in this embodiment, the sealing member 5 is provided in the peripheral part of the lower surface of the closing plate part 2 of the pipe joint 1. By this sealing member 5, the adhesiveness between the closing plate part 2 and the annular part 8c of the lid frame 8 can be enhanced, and the sealing performance can be improved. Therefore, it can prevent more reliably that an odor leaks outside. The seal member 5 is preferably made of an elastic material. If the seal member 5 is crushed by the weight of the pipe joint 1 other than the seal member 5 and is brought into close contact with the closing plate portion 2 and the annular portion 8c of the lid frame 8, deodorization can be more reliably achieved.

  In the present embodiment, the pipe joint 1 includes an attachment portion 9 to which the chain 12 is attached. The pipe joint 1 and the lid 11 are connected by a chain 12. Therefore, the lid 11 is removed from the lid frame 8 when the temporary toilet 20 is installed, but the lid 11 can be prevented from being lost during the use period of the temporary toilet 20. However, the chain 12 and the attachment portion 9 are not necessarily required. The pipe joint 1 and the lid 11 may not be connected.

  Although one embodiment of the present invention has been described above, it is needless to say that the embodiment of the present invention is not limited to the above embodiment.

  In the said embodiment, although the valve body 4b of the deodorizing valve 4 is supported by the support shaft 4c so that rocking | fluctuation is possible, the opening / closing structure of the valve body 4b is not specifically limited. The structure of the deodorizing valve 4 is not limited at all. Various known deodorizing valves can be used as the deodorizing valve provided in the pipe joint.

  In the said embodiment, the number of the valve bodies 4b is one. However, the number of valve bodies 4b is not particularly limited. Moreover, in the said embodiment, although the number of deodorizing valves with which a pipe joint is provided is one, two or more may be sufficient. However, if the number of valve bodies and the number of deodorizing valves are large, maintenance such as cleaning and inspection tends to be troublesome.

  The inner peripheral surface of the connection port 3a may be a smooth surface or may have a spiral groove. That is, the connection port 3a may be configured so that the pipe member can slide, or may be configured to be screwed. The connection port 3a may be a so-called adhesion port or a rubber ring port, may be various types of ports, and may have a screwed structure (cap nut or the like).

  In the above embodiment, the temporary toilets 20 and 30 are installed directly above the pipeline 10, but the installation positions of the temporary toilets 20 and 30 are not limited. The temporary toilets 20 and 30 are installed above the pipeline 10. The term “installed above the pipeline 10” as used herein means that the temporary toilets 20 and 30 are installed at a higher position than the pipeline 10. Means.

  The seal member 5 improves the sealing performance between the pipe joint 1 and the lid frame 8 in order to prevent odor from leaking to the outside, but the arrangement thereof is not particularly limited. In the embodiment, the seal member 5 is provided on the peripheral edge of the lower surface of the closing plate portion 2 and is disposed between the lower surface of the closing plate portion 2 and the upper surface of the annular portion 8 c of the lid frame 8. However, it is not particularly limited, and other arrangements are possible. For example, the sealing member 5 may be provided on the periphery of the closing plate portion 2, and the sealing member 5 may be interposed between the periphery of the closing plate portion 2 and the inner wall of the tube portion 8 a of the lid frame 8.
