Description

  The present invention relates to a pipe suspending device for suspending a pipe such as a sewer pipe or a fume pipe buried in the ground at a predetermined position in a groove.

  For example, in the construction of a sewer pipe, which is a type of pipe, a groove is formed by excavating the ground, and a pipe is laid in this groove. To facilitate this, the slope of the sewer pipe must be set precisely. Therefore, conventionally, as proposed in Non-Patent Document 1, a pipe suspension device for facilitating pipe laying work is used between earth retaining panels or sheet piles installed on both sides of the groove. It was.

  As shown in FIG. 8, the pipe suspension device of Non-Patent Document 1 is expressed in such a state that the vertical axis portion is simply welded to the base pipe and the horizontal screw of the horizontal axis portion. In addition, welding or screwing using a large number of members is performed to connect or attach the vertical axis portion to the base pipe and the horizontal screw of the horizontal axis portion. In other words, in the conventional pipe suspension device, the connection or attachment of the vertical axis portion to the base pipe and the horizontal screw of the horizontal axis portion is an operation that requires a great number of parts and labor. .

  Not only that, but the connection or attachment of the vertical axis to the base pipe and the horizontal screw of the horizontal axis uses many metal members, so that the overall weight of the pipe suspension is considerably heavy. In addition, the work itself of placing the pipe suspension device between the earth retaining panel or the sheet pile installed in the groove is a heavy labor. Since the pipe itself to be suspended by the pipe suspension device is heavy, the connection or attachment of the longitudinal axis portion to the base pipe and the horizontal screw must be performed by a rigid metal member. The weight of the entire suspension device is very large.

  In addition, if the vertical axis is connected or attached to the base pipe and the horizontal screw by “welding” many members, if you want to replace only the base pipe or the horizontal screw, Therefore, it is virtually impossible to replace parts in this type of pipe suspension device. This kind of pipe suspending device is used in order to install one pipe horizontally, and moreover, when performing sewerage work using many pipes, Since at least twice the number of pipe suspension devices must be used, and because they are used repeatedly, the fact that the replacement of parts is virtually impossible is also a heavy work with poor workability. In addition, the cost of the pipe suspension device is not only very high, but also inconvenient.

  Therefore, the present inventors do not need to perform connection or attachment of the vertical axis portion to the base pipe and the horizontal screw of the horizontal axis portion by “welding” for this type of pipe suspension device, and it is easy to replace parts. As a result of various studies on how to reduce the weight for improving workability, the present invention has been completed.

  That is, an object of the present invention is to provide a pipe suspending device that can be easily manufactured, parts can be easily replaced, and the weight can be reduced.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.

Characterized pipe suspension device 100 "
It is.

  That is, as shown in FIG. 1, the pipe suspension device 100 is supported by the horizontal shaft portion 10 disposed between the earth retaining panel or the sheet pile installed in the groove, and the horizontal shaft portion 10. A vertical axis part 20 for suspending a pipe to be laid therein and a pipe attachment part 30 provided at the lower end of the vertical axis part 20 are provided.

  The horizontal shaft portion 10 includes at least a base pipe 11 positioned at an upper portion of the pipe suspension device 100 and a horizontal screw 12 supported in parallel to the lower side of the base pipe 11. The vertical axis part 20 is connected to the part 10 by a guide frame 40, and a pipe attachment part 30 for suspending a pipe is provided at the lower end of the vertical axis part 20.

  As shown in FIGS. 1 to 3, the guide frame 40 has a horizontal insertion portion 41 through which the base pipe 11 is inserted, a vertical insertion portion 42 orthogonal to the horizontal insertion portion 41, and a horizontal passage through which the horizontal screw 12 is inserted. The screw insertion part 43, and these horizontal insertion part 41, the vertical insertion part 42, and the connection part 44 which integrates the horizontal screw insertion part 43 are provided, These horizontal insertion part 41, vertical insertion The part 42, the horizontal screw insertion part 43, and the connection part 44 are integrally formed by, for example, aluminum die casting. In other words, the horizontal insertion portion 41 and the horizontal screw insertion portion 43 are connected in parallel to each other by the connection portion 44, and the vertical insertion portion 42 is connected to the horizontal insertion portion 41 and the horizontal screw insertion portion 43 by the connection portion 44. They are connected so as to be in an orthogonal state, and these relations are made unchanged by the connecting portion 44.

  If such a guide frame 40 is formed, the base pipe 11 of the horizontal shaft portion 10 is inserted into the horizontal insertion portion 41, the horizontal screw 12 is inserted into the horizontal screw insertion portion 43, and the vertical axis is inserted into the vertical insertion portion 42. If the part 20 is attached, the pipe suspension device 100 can be easily manufactured or assembled. Both ends of the horizontal screw 12 are supported by brackets 50 to be described later, and each bracket 50 is attached to both ends of the horizontal insertion portion 41 by insertion portions 51 located at the upper ends thereof.

  Now, as shown in FIG. 1, when the pipe suspension device 100 as described above is arranged between the earth retaining panels or sheet piles installed in the groove and is in a fixed state, the guide frame 40 is moved to the horizontal shaft portion 10. The base pipe 11 and the horizontal screw 12 constituting the above can be slid in the horizontal direction at the horizontal insertion portion 41 and the horizontal screw insertion portion 43. For example, fixed handles 60 are attached to the horizontal screws 12 located on both sides of the horizontal screw insertion portion 43, respectively.

  Here, when it is desired to adjust the position of the guide frame 40 in the left-right direction in FIG. 1, before the pipe is attached to the pipe attachment portion 30, the fixing handle 60 on the side to be moved is loosened to the side. After securing the allowable moving part of the screw insertion portion 43, the fixed handle 60 on the opposite side is tightened, whereby the fixed handle 60 is screwed on the horizontal screw 12 in the direction to be moved. At this time, since the horizontal insertion portion 41 of the guide frame 40 is merely inserted through the base pipe 11 on the horizontal shaft portion 10 side, the movement of the guide frame 40 is performed between the base pipe 11 and the horizontal screw 12. This is done while maintaining the parallel state. The same applies to the movement of the guide frame 40 in the opposite direction to that described above.

  When the guide frame 40 moves in the desired direction in this way, the vertical insertion portion 42 formed integrally with the guide frame 40 also moves the same amount in the left-right direction. And since a pipe is attached to the lower end of this vertical insertion part 42 by the pipe attachment part 30, the position adjustment of this pipe in the left-right direction shown in FIG. 1 is made. The vertical position adjustment of the pipe can be performed by rotating the fixed handle 60 provided on the vertical axis portion 20.

  As described above, the pipe suspension device 100 including the guide frame 40 is assembled with the base pipe 11 and the horizontal screw 12 and the vertical axis portion 20 constituting the horizontal axis portion 10 by the guide frame 40. The attachment can be performed very easily, and at least the parts of the horizontal axis portion 10 and the vertical axis portion 20 can be easily replaced.

The pipe suspension device 100 according to this embodiment is the invention according to each claim. Therefore, the following description will focus on the pipe suspending device 100 according to this embodiment.

  FIG. 1 shows a pipe suspending device 100 according to the present invention in a front view in a state where it is installed between a retaining panel or a sheet pile. This pipe suspending device 100 suspends a horizontal shaft 10 disposed between a retaining panel or a sheet pile installed in a groove, and a pipe to be laid in the groove supported by the horizontal shaft 10. The vertical axis part 20 to be lowered, the pipe mounting part 30 provided at the lower end of the vertical axis part 20, the guide frame 40 for connecting the horizontal axis part 10 and the vertical axis part 20, the base pipe 11 and the horizontal screw 12 And a pair of left and right brackets 50 that perform connection with each other.

  The horizontal shaft portion 10 of the pipe suspension device 100 includes a base pipe 11 positioned at an upper portion and a horizontal screw 12 disposed in parallel to the base pipe 11 and positioned below the base pipe 11. It is a member. The base pipe 11 can accommodate therein the position adjusting screw 13 shown in FIG. 6 and the position adjusting pipe 14 shown in FIG. 7, and the position adjusting screw 13 and the position adjusting pipe 14 are pulled out.

The part 42, the horizontal screw insertion part 43, and the connection part 44 are integrally formed by, for example, aluminum die casting. In other words, the horizontal insertion portion 41 and the horizontal screw insertion portion 43 are connected in parallel to each other by the connecting portion 44 of the guide frame 40, and the vertical insertion portion 42 is connected to the horizontal insertion portion 41 and the horizontal screw insertion portion 43. They are connected so as to be in an orthogonal state, and these relationships are not changed by the connecting portion 44. If the base pipe 11 of the horizontal shaft portion 10 is inserted into the horizontal insertion portion 41 of the guide frame 40, the horizontal screw 12 is inserted into the horizontal screw insertion portion 43, and the vertical portion 20 is attached to the vertical insertion portion 42, The pipe suspending device 100 can be easily manufactured or assembled.

  In the pipe suspending device 100 of this embodiment, the above-described guide frame 40 is formed of a metal or metal alloy having a specific gravity of 1.7 to 4.0. For example, “steel” that generally forms this kind of pipe suspension device 100 is lightened in a state in which a sufficient rigidity is ensured.

  The guide frame 40 is slidable in the lateral direction with respect to the base pipe 11 and the horizontal screw 12 constituting the horizontal shaft portion 10 at the horizontal insertion portion 41 and the horizontal screw insertion portion 43. For example, as described above, the fixed handles 60 are attached to the horizontal screws 12 positioned on both sides of the horizontal screw insertion portion 43.

  Here, when it is desired to adjust the position of the guide frame 40 in the left-right direction in FIG. 1, before the pipe is attached to the pipe attachment portion 30, the fixing handle 60 on the side to be moved is loosened to the side. After securing the allowable moving part of the screw insertion portion 43, the fixed handle 60 on the opposite side is tightened, whereby the fixed handle 60 is screwed on the horizontal screw 12 in the direction to be moved. At this time, since the horizontal insertion portion 41 of the guide frame 40 is merely inserted through the base pipe 11 on the horizontal shaft portion 10 side, the movement of the guide frame 40 is performed between the base pipe 11 and the horizontal screw 12. This is done while maintaining the parallel state. The same applies to the movement of the guide frame 40 in the opposite direction to that described above.

  When the guide frame 40 moves in the desired direction in this way, the vertical insertion portion 42 formed integrally with the guide frame 40 also moves the same amount in the left-right direction. And if a pipe is attached to the lower end of this vertical insertion part 42 by the pipe attachment part 30, the position adjustment of this pipe in the left-right direction shown in FIG. 1 will be made. As described above, the vertical position adjustment of the pipe can be performed by rotating the fixed handle 60 provided on the vertical axis portion 20.

  As shown in FIGS. 4 and 5, the bracket 50 includes an insertion portion 51 through which the base pipe 11 constituting the horizontal shaft portion 10 is inserted, and a horizontal screw 12 arranged in parallel with the base pipe 11. These are integrated with a screw fixing portion 52 for fixing both ends of the base pipe 11 and connects the base pipe 11 and the horizontal screw 12 together.

  That is, in the pipe suspension device 100 of this embodiment, the base pipe 11 and the horizontal screw 12 are connected using a pair of left and right brackets 50 as shown in FIGS. . First, the bracket 50 is attached to and fixed to the base pipe 11 of the horizontal shaft portion 10 by inserting the insertion portions 51, which are the upper end portions thereof, into both end portions of the base pipe 11, as shown in FIGS. This is done by screwing the fixing screw 53 a to the fixing portion 53.

  When these brackets 50 are attached to both ends of the base pipe 11, both ends of the horizontal screw 12 on the side of the horizontal shaft portion 10 are inserted or fixed in the screw fixing portions 52 formed at the bottom of each bracket 50. When the fixing of each bracket 50 to the base pipe 11 is completed, the parallel mounting of the horizontal screw 12 to the base pipe 11 is automatically completed.

  If the above operations are performed in reverse, not only the bracket 50 but also the base pipe 11 and the horizontal screw 12 can be easily replaced. Further, these brackets 50 are integrally formed by, for example, aluminum die casting, and are symmetric when viewed at the center of the screw fixing portion 52, and the left and right brackets 50 can be manufactured with one mold. As a result, the production of the pipe suspension device 100 is facilitated.

  In the pipe suspension device 100 of this embodiment, the bracket 50 described above is formed of a metal or metal alloy having a specific gravity of 1.7 to 4.0, and as a result, the pipe suspension device 100 is necessary and sufficient. In a state in which a sufficient rigidity is ensured, for example, “iron” that generally forms this kind of pipe suspension device 100 is reduced in weight.

  In addition, when integrally forming the bracket 50 by aluminum die casting, as shown in FIGS. 4 and 5, it is preferable to have the space portion 54, rather than forming a so-called “solid”. The weight of the bracket 50 itself can be reduced, and as a result, the overall weight of the pipe suspension device 100 can be reduced.
