Description

  The present invention relates to a structure for preventing uneven settlement of piping that is communicated from the inside of a house and is buried in the outer periphery of the house.

  Conventionally, foundations such as pile foundations, cloth foundations, and solid foundations are provided in order to prevent settlement of houses when constructing houses. In particular, when the residential land is soft ground or constructed ground, steel pipe piles and columnar improvements are applied to support the load of the house with a solid support layer in the ground. By doing in this way, it can prevent that a house sinks into the ground.

  By the way, in the above-mentioned houses, the house itself hardly sinks, but the ground around the house may sink because it is not firmly supported. Therefore, uneven settlement occurs between the house and the surrounding ground due to the difference in the amount of settlement, and there is a risk that the pipes embedded in the outer periphery of the house are loaded and the pipes and joints are damaged and water leaks.

  In view of this, for example, a pipe damage prevention structure is known in which a pipe extending from a house to a drain is provided with a flexible joint that allows vertical displacement. Such a breakage prevention structure absorbs the settlement difference between the pipe embedded in the house part and the pipe embedded in the outdoor part by the flexible joint.

Further, for example, as shown in FIG. 19, a support pipe 101 that is driven into a strong support layer 100 in the ground and a pipe 102 that is attached to the upper end of the support pipe 101 and is embedded in the outer periphery of the house are received. A piping support 104 composed of a saddle 103 has been proposed (for example, Patent Document 1). By supporting the pipe 102 with such a pipe support 104, both the house and the pipe 102 are supported by the strong support layer 100, so that uneven settlement occurs between the house and the pipe 102. Without any problem, the pipe 102 and the joint can be prevented from being damaged and leaking water.

  However, the method of interposing a flexible joint between the pipe coming out of the house and the external pipe surely absorbs the difference in settlement between the house and the outdoor pipe, but the pipe slope is uneven due to uneven settlement between the drains. It may change or cause damage to the drainage pipe connecting the drainage basins.

  Further, when the pipe support 104 as described above is used, it is necessary to penetrate the support pipe 101 up to the strong support layer 100. If the work takes time and the support layer 100 is considerably deep, Depending on the depth, a long support pipe 101 is prepared, and the installation cost tends to be high.

  Accordingly, an object of the present invention is to provide an unequal subsidence prevention structure for an outdoor pipe that can very easily suppress the occurrence of unequal subsidence between a house and an outdoor pipe and between outdoor pipes. And

  In order to achieve the above object, the unequal settlement prevention structure for outdoor piping according to claim 1 supports a base plate placed on a supporting ground and a bottom reinforcing bar extending upward from the base plate.

In this case, as shown in FIG. 11, the pipe 7 can be fixed by disposing the pipe 7 below the extending member 14 and fitting the U-shaped holding member 15 from the lower side thereof. This is suitable when the pipe 7 is arranged at a horizontal level slightly lower than the horizontal level of the base plate 51.

  Further, the shape of the extending member 14 is not limited to the above plate shape, and the extending member 14 having a different shape can be used according to the gradient of the pipe to be supported. For example, the above-described plate-like extending member 14 extends to a horizontal level substantially equal to the base plate 51 of the reinforcing bar base 5, but further downstream, the pipe is positioned at a position considerably lower than the base plate 51 due to the gradient of the pipe 7. 7 is buried. In such a case, as shown in FIG. 12, the extending member 14 is bent substantially perpendicularly downward from one end side connected and fixed to the support stay 6 to extend to a predetermined depth in a substantially vertical direction. Then, a crank-like extending member 14 that is bent again in the horizontal direction and in which the support portion 16 is formed in the horizontal portion can be used. And also when this crank-shaped extension member 14 is used, similarly to the case where the plate-like extension member 14 is used, the pipe 7 is placed on the upper side of the support portion 16, and an inverted U-shape is formed from above. The pipe 7 is fixed by fitting the holding member 15 of the mold. In such a crank-like extending member 14, reinforcing ribs 18 are formed at the bent portions in order to maintain the strength.

That is, the pipe 7 may be fixed by disposing the pipe 7 on the lower side of the extending member 14 and fitting the U-shaped holding member 15 from the lower side thereof.

  Thus, by using several types of extending members 14 having different shapes, and selecting whether the piping 7 and the holding member 15 are installed on the upper side or the lower side of the extending member, the piping 7 The horizontal level of the pipe 7 can be adjusted, and the pipe 7 can be fixed with an appropriate slope. However, when the slope of the pipe 7 is further adjusted, as shown in FIG. A support plate 17 is provided at an intermediate position between the two legs 151 of the holding member 15, and the pipe 7 is supported such that the pipe 7 is sandwiched between the curved portion 152 of the holding member 15 and the upper surface of the support plate 17. Can be fixed. The leg portion 151 of the holding member 15 is provided so as to penetrate the support portion 16, and the length of the leg portion 151 can be adjusted by adjusting the position of the nut. The horizontal level of the buried pipe can be finely adjusted by adjusting.

  For example, by loosening a nut that connects and fixes the support portion 16 and the leg portion 151 of the holding member 15 in the support portion 16 of the extending member 14 and pressing it downward, the nut is tightened and fixed again at a desired position. The horizontal level of the pipe 7 can be lowered. For example, a screw groove is preferably formed on the entire outer peripheral surface of the leg portion 151 of the holding member 15. With this configuration, the position where the pipe 7 is supported and fixed can be adjusted steplessly. Even when the horizontal level of the pipe 7 to be embedded is adjusted by adjusting the length of the leg 151 of the holding member 15 as described above, as shown in FIG. The pipe 7 and the holding member 15 may be installed on the lower side. In this way, piping can be installed at a deeper position. Although the crank-shaped extending member 14 is used in FIG. 15, the extending member 14 may be a plate-like member extending in the horizontal direction in this case as well.

  Further, the number of the pipes 7 supported by the pipe support member 8 is not limited to one and may be a plurality. For example, as shown in FIG. 16, one pipe 7 is supported and fixed by the support plate 17 and the curved part 152 of the holding member 15 above the support part 16 of the extending member 14, and another pipe 7 is supported by the support part. It may be supported and fixed so as to be sandwiched between 16 and the support plate 17. In this case, the plurality of pipes 7 can be installed in parallel in the height direction by adjusting the length of the leg 151 of the holding member 15 and using the plurality of support plates 17. In addition, as shown in FIG. 17, the support portion 16 of the extending member 14 is formed to be slightly long, a plurality of pipes 7 are arranged in the horizontal direction, and the holding member 15 is fixed from above each pipe 7 to be fixed. It may be.
