Description

  The present invention relates to an insert, and supports a pipe support for discharging sewage disposed in a building, structure or other object (hereinafter referred to as “building or the like”) provided in the building or the like. The present invention relates to a thing that does not conduct vibration or noise generated from piping to a building or the like.

  In the case of a relatively old building, the sewage discharge pipe is provided along the outer wall surface of the building. In recent buildings and large buildings, the sewage discharge pipe may be disposed using the indoor space or the wall space. In any case, the sewage discharge pipe is installed in the building as follows.

  As illustrated in FIG. 9, the anchor 63 is embedded in the wall body 61 of the building through the wall surface 62 in the height direction with an appropriate gap, and the arm 64 is protruded from the anchor 63. A connecting rod 65 is arranged coaxially with the arm 64, and the opposite ends of both are inserted into the box frame 66 so as not to escape by the heads 67, 68. A cushioning material 69 is interposed between the two. The attachment plate 70 at the end of the connecting rod 65 is sandwiched between a pair of ear pieces 73 of a pipe band 72 provided to the sewage discharge pipe 71. When bolts 74 are inserted into the through holes of both ear pieces 73 and mounting plate 70 and tightened with nuts 75, sewage discharge pipe 71 is separated from wall surface 62 and supported by wall body 61.

In addition, as a device for preventing the vibration of the drain pipe, a work is performed in the drain pipe, and an elastic material is provided between the peripheral surface of the support hole formed in the drain pipe and the floor slab (Japanese Patent Laid-Open No. 2003-56744). No. 1) and an elastic material applied to the inner peripheral surface of a drain pipe support band (Japanese Patent Laid-Open No. 2001-348926) are known.

  In the case of a flush toilet, a large amount of sewage flows at a time. Since the flow is not uniform and the pipe may flow down while repeatedly colliding with the pipe wall, the sewage discharge pipe vibrates, and noise is generated along with the occurrence of the vibration. Since the conventional sewage discharge pipe is rigidly connected to the wall, this vibration is transmitted to the wall through the pipe band, arm and anchor, and further, vibration and noise are transmitted to the room. Such vibrations and noises cause discomfort to residents, not only in hospital wards and residential buildings, but also in office buildings.

Since the thing of Unexamined-Japanese-Patent No. 2003-56744 arranges an elastic material between the surrounding surface of a drain pipe and a support hole, it cannot employ | adopt when piping along the outer surface of a wall surface. Moreover, since the thing of Unexamined-Japanese-Patent No. 2001-348926 has given the elastic material to the pipe band, when using it outdoors, an elastic material shrinks and solidifies with time change under the influence of wind and rain etc. However, rattling occurs on the support surface and noise is generated.
An object of the present invention is to provide an anti-vibration insert that does not transmit the vibration of a sewage discharge pipe to the room over a long period of time, even indoors as well as indoors.

The first insert according to the present invention is provided with an elastic coating that is a molded product separate from the main body on the outer surface of the main body, leaving an opening of the main body, and the molded product is inserted into the cylindrical portion having the opening at one end. A receiving portion of the flange that follows the hole and the insertion hole, and the receiving portion is formed on the opposite side of the insertion hole and follows the receiving port whose inner dimension is smaller than the outer dimension of the flange .

  The second insert according to the present invention surrounds the opening of the main body, fits one end portion of the cylindrical body to the outer peripheral portion of the main body, and leaves the mounting opening of the other end portion of the cylindrical body, the main body and the cylinder It comprises an elastic coating on the outer surface of the body.

  The edge of the receiving port may have a notch in a part thereof.

  The elastic coating may be made of plastic.

  The elastic coating may be made of rubber.

The first insert according to the present invention is provided with an elastic coating, which is a molded product separate from the main body, leaving an opening of the main body, and therefore, there is a place restriction on the integration of the two. not, vibration transmitted from the outside to the body has never transmitted to the wall is absorbed by the elastic coating does not adversely unpleasant vibration and noise in the room of the occupants.
Further, the molded product has a housing portion for the flange that follows the insertion hole of the cylindrical portion having the opening at one end, and the housing portion is on the side opposite to the insertion hole, and the inner dimension is larger than the outer dimension of the flange. Adhering to the elastic coating is good because it follows the small receiving port, and the possibility of peeling off is very low. The cylindrical portion of the main body is inserted into the insertion hole from the receiving port, and the mouth of the receiving port By spreading the flange and storing the flange in the storage portion, the molded product can be easily and closely covered with the main body.

  The second insert according to the present invention surrounds the opening of the main body, fits one end portion of the cylindrical body to the outer peripheral portion of the main body, and leaves the mounting opening of the other end portion of the cylindrical body, the main body and the cylinder Since the outer surface of the body is provided with an elastic coating, inserts are embedded in the wall from the surface, thus preventing corrosion caused by rainwater flowing down the wall surface, and vibration transmitted from the outside to the cylinder and the body. Is not absorbed by the elastic coating and transmitted to the wall body, and does not cause unpleasant vibrations or noises to indoor residents.

  If the edge portion of the receiving port has a notch in a part thereof, the edge portion can be expanded outward at the end of the notch portion, so that the receiving port can be expanded. Storage becomes easy.

  If the elastic coating is made of plastic, it is hardly corroded, so that its effectiveness is not deteriorated even if it is buried in the wall for a long time.

  If the elastic coating is made of rubber, it will be well adapted to the wall and absorb vibration very effectively.

Throughout the drawings, the same reference numerals indicate the same or corresponding parts.
FIG. 1 shows a specific example of a first insert according to the present invention. Reference numeral 1 denotes a main body, 11 an opening thereof, and 2 an elastic coating. The elastic coating 2 covers the outer surface of the main body 1 without leaving the opening 11 of the main body 1, that is, without closing the opening 11.
The insert is attached to the mold 41 as follows, for example. The screw rod 44 of the bolt 43 is inserted into the mounting hole 42 formed in the mold frame 41, and the nut 35 is screwed onto the screw rod 44 on the opposite side of the mold frame 41 and tightened to attach the bolt 43 to the mold frame 41. The opening 11 of the main body 1 is screwed to the bolt 43 and tightened.
When the installation of the insert is completed, the concrete 46 is poured into the mold 41, and after the solidification is completed, a product in which the insert is embedded is obtained.
FIG. 8 shows the product used as the wall 47. This insert is used to support the sewage discharge pipe 48 disposed along the wall body 47.
This insert is embedded in the wall body 47 at an appropriate interval on the wall surface 49. From each of these inserts, an arm 51 having a plate-like attachment piece 5 at the tip is protruded. A pipe band 52 is wound around the sewage discharge pipe 48 so as to face each arm 51, and the plate-shaped attachment piece 5 of the arm is sandwiched between a pair of ear pieces 53, 53 of each pipe band. Since the mounting piece 5 and the both ear pieces 53, 53 are provided with bolt insertion holes, if these bolt insertion holes are matched and tightened with the bolts and nuts 54, the sewage discharge pipe 48 is separated from the wall surface 49 by the wall. Supported by the body 47.
When a large amount of sewage flows into the sewage discharge pipe 48 at a time, the sewage discharge pipe 48 vibrates and generates noise. This vibration is transmitted to the main body 1 through the pipe band 52 and the arm 51. Since the periphery of the main body 1 is covered with the elastic coating 2, this vibration is absorbed by the elastic coating 2 and is not transmitted to the wall body 47. Therefore, no vibration is transmitted to the room, no noise is generated, and no uncomfortable feeling is given to the resident.

FIG. 2 shows a specific example of the second insert according to the present invention. Reference numeral 1 denotes a main body, 3 denotes a cylindrical body that surrounds the opening 11 of the main body 1 and is fitted to the outer peripheral portion of the main body 1. The outer surface is provided with an elastic coating 2.
The difference from the first insert is that the cylindrical body 3 is present, and that the opening 11 can be positioned at a location recessed from the wall surface 49 of the wall body 47. Since the opening 11 is not exposed to the rainwater flowing down along the wall surface 49, the corrosion resistance is improved. As for the other effects, the description of the first insert is applicable to the case of the second insert, and the description thereof will be omitted.

  The main body 1 includes a cylindrical portion 12 having an opening 11 at one end and a flange 13 at the other end. In this case, the adhesiveness with the elastic coating 2 is good and the possibility of peeling off is very small.

  The elastic coating 2 is a molded product 21 separate from the main body 1. In this case, there is no place restriction on the integration work of the elastic coating 2 and the main body 1.

  The elastic coating 2 is an attached product 22 integrated with the main body 1. In this case, by making the elastic coating 2 into a liquid material, a coated product can be easily manufactured simply by immersing the main body 1 in the liquid material.

  The molded product 21 has an insertion hole 23 of the cylindrical portion 12 and a storage portion 24 of the flange 13 following the insertion hole 23, and the storage portion 24 is on the side opposite to the insertion hole 23 and has an inner dimension d outside the flange 13. It continues to the receiving port 25 which is smaller than the dimension D. In this case, the cylindrical part 12 of the main body 1 is inserted into the insertion hole 23 from the receiving port 25, the lip of the receiving port 25 is widened, and the flange 13 is stored in the storage unit 24. And can be covered closely.

  The edge portion 26 of the receiving port 25 has a cutout portion 27 at a part thereof. In this case, since the edge portion 26 is expanded outward at the end of the notch portion 27 and the receiving port 25 is expanded, the flange 13 can be easily stored in the storage portion 24.

  The elastic coating 2 is an attached product 32 integrated with the main body 1 and the cylindrical body 3. In this case, it is easy to apply the elastic coating 2 to the main body 1 and the cylindrical body 3, the integration is performed reliably, and there is no possibility of detachment.

  The elastic coating 2 is made of plastic. In this case, since it is hardly corroded, even if it is buried in the wall body 47 for a long time, there is no fear of deterioration of the effect.

  The elastic coating 2 is made of rubber. In this case, the wall body 47 is well adapted and vibration absorption is extremely effective.

  The rubber has a hardness of 60 degrees. In this case, the sewage discharge pipe 48 is sufficiently supported and the vibration absorbing effect is also good.
