Description

  The present invention relates to a startup structure of a flexible pipe used as a water supply / hot water supply pipe or the like in a building.

  Flexible pipes for water supply and hot water supply are generally piped under the floor of a building, and are set up on the floor at positions where water supply and hot water supply facilities such as sinks and washstands are installed. Since the flexible piping itself cannot hold the startup posture, it is necessary to hold the startup posture with some auxiliary member.

  Conventionally, as a means for raising a flexible pipe from the floor to the floor, a structure in which a support is fixed to the foundation concrete of the building and the rise of the flexible pipe is supported by this support is known. (See Patent Document 1).

  Further, a structure in which a support rod is set up on an underfloor slab (concrete concrete) and a rising portion of a flexible pipe is supported on the support rod is also known (see Patent Document 2).

  A drainage pipe is usually set up near the start-up portion of the flexible pipe for water supply and hot water supply. The drainage pipe is thicker and more rigid than the flexible pipe for water supply and hot water supply (usually a PVC pipe is used), so it is possible to hold the startup posture by itself. . When starting up a flexible pipe, it is necessary to keep the positional relationship with the start-up part of the pipe having this rigidity exactly as designed.

  However, the conventional flexible piping startup structure described above is designed to install the flexible piping on the floor because the support and support rod are individually installed without considering the positional relationship with the startup section of the rigid piping. When connecting to the pipe, the proper positional relationship with the rigid pipe cannot be maintained, and pipe connection on the floor may be difficult.

  Also, at the start-up part of the flexible pipe, after stretching the floor, a hole is drilled in the floor and the flexible pipe is led out on the floor, but the hole drilling position is determined by measuring the dimension from the reference position. For this reason, the position of the hole may be shifted from the starting position of the flexible pipe due to a measurement error or the like. In this case, the flexible pipe is forced to bend so as to fit the hole in the floor and the hole is passed through, so that the flexible pipe may be buckled.

  In addition, the start-up structure using the support bar is in a state where the support bar with a sharp tip protrudes from the soil concrete before the floor is stretched. There is a problem.

  In addition, if insulation is attached to the lower surface of the floor, the insulation is missing when holes are drilled in the floor or when piping is moved when piping is connected on the floor. May be reduced.

  In addition, after the flexible piping and rigid piping are led out on the floor, caulking material is filled in the gap around the piping in the floor hole to ensure the airtightness in the room, but work in a narrow space Therefore, there are cases where the caulking material can be sufficiently filled and the airtightness cannot be ensured.

  The first object of the present invention is that the positional relationship with the rigid pipe can be accurately maintained, the drilling position of the floor is not shifted from the starting position of the flexible pipe, and the operator is not injured. The object is to provide a flexible piping startup structure.

  A second object of the present invention is to provide a flexible pipe start-up structure in which the heat insulating property does not deteriorate even if the heat insulating material attached to the lower surface of the floor is lost by drilling or the like.

  A third object of the present invention is to provide a flexible pipe start-up structure that can easily ensure the airtightness above and below the floor where the pipe penetrates the floor.

  The present invention is a structure of a portion where a flexible pipe piped under the floor is raised on the floor, and a first hole through which the rigid pipe is inserted and a second hole through which the flexible pipe is inserted are formed. Using a plate-like holding member, the rigid pipe rising portion is inserted into the first hole of the plate-like holding member, the flexible pipe rising portion is inserted into the second hole, and the plate-like holding member is inserted. Is fixed to the lower surface of the floor.

  The plate-like holding member used in the present invention has an adhesive layer on the upper surface, and it is preferable to fix the plate-like holding member to the lower surface of the floor by bonding.

  Moreover, it is preferable that the plate-shaped holding member used for this invention is a thing in which the one part or all part of the thickness direction is comprised with the heat insulating material.

  The plate-like holding member used in the present invention is provided with a sealing member that seals a gap between the inner peripheral surface of the hole and the outer peripheral surface of the pipe in at least one of the first hole and the second hole. Is preferred

  According to the present invention, since the plate-like holding member in which the first hole for inserting the rigid pipe and the second hole for inserting the flexible pipe are used, the rising portion of the rigid pipe is flexible. In addition to being able to accurately maintain the positional relationship with the start-up portion of the flexible piping, the drilling position of the floor is also clarified, and there is no possibility that the flexible piping will be bent and buckled due to an error in the drilling position of the floor. In addition, since the plate-like holding member is fixed to the lower surface of the floor, there is no possibility of the plate-like holding member slipping or rotating, and the rising portion of the flexible pipe is securely held at an accurate position. be able to. Furthermore, since there is no member protruding from the soil concrete, there is no risk of injury to the operator.

  Further, by providing an adhesive layer on the upper surface of the plate-like holding member, the plate-like holding member can be easily fixed to the floor lower surface.

  In addition, if part or all of the thickness direction of the plate-like holding member is made of a heat insulating material, the heat insulating material of the plate-like holding member covers the missing portion even if a part of the heat insulating material on the lower surface of the floor is missing. Therefore, heat insulation can be secured.

  Furthermore, by providing a sealing member that seals the gap between the inner peripheral surface of the hole and the outer peripheral surface of the pipe in at least one of the first hole and the second hole of the plate-like holding member, the pipe can Without filling the caulking material in the portion penetrating the floor, airtightness at the top and bottom of the floor can be ensured and workability is improved.

Embodiment 1 FIGS. 1 and 2 show an embodiment of the present invention. In the figure, 10 is a floor of a building, 12 is foundation concrete, 14 is soil concrete, 16 is a rigid pipe for drainage made of PVC pipe, 18 is a flexible pipe for water and hot water supply, and 20 is a flexible pipe. This is a plate-like holding member that holds 18 rising portions 18a. The rigid pipe 16 is supported by the support fitting 22 and piped on the soil concrete 14 and rises vertically at a predetermined position. Since the rigid pipe 16 has rigidity, it can hold the startup posture by itself.

  As shown in FIG. 2, the plate-like holding member 20 has a predetermined positional relationship between a first hole 24 through which the rigid pipe 16 is inserted and a second hole 26 through which the flexible pipe 18 is inserted. It is formed as follows. An adhesive layer 28 is provided on the upper surface of the plate-like holding member 22.

  The first hole 24 of the plate-like holding member 20 is formed to have a size that fits with the rigid pipe 16. When the rising portion 16 a of the rigid pipe 16 is inserted into the first hole 24, the plate-like holding member 20 is It is designed to be kept almost horizontal. In order to keep the plate-like holding member 20 horizontal, it is preferable that the cylindrical portion 30 having the same inner peripheral surface as the first hole 24 is protruded from the lower surface of the plate-like holding member 20. However, if the plate thickness of the plate-like holding member 20 is increased, the cylindrical portion 30 is unnecessary. The plate-like holding member 20 is attached to the rising portion 16a of the rigid pipe 16 before the floor 10 is stretched.

  The flexible pipe 18 is piped on the soil concrete 14 and is started up near the start-up portion 16a of the rigid pipe. The rising portion 18 a of the flexible pipe 18 is led out to the floor through the second hole 26 of the plate-like holding member 20. A hole is formed in the floor 10 in accordance with the second hole 26 of the plate-like holding member 20. The plate-like holding member 20 is fixed to the lower surface of the floor 10 by the adhesive layer 28 so as not to slide down. The rising portion 18 a of the flexible pipe 18 is raised substantially vertically by being inserted into the second hole 26 of the plate-like holding member 20. The positional relationship between the rising portion 16a of the rigid pipe and the rising portion 18a of the flexible pipe can be held as designed by the plate-like holding member 20.

  Although only one flexible pipe 18 is shown in FIG. 1, normally, a flexible pipe for water supply and a flexible pipe for hot water supply stand up near the start-up portion 16a of the rigid pipe. For this reason, the plate-like holding member 20 is formed with two second holes 26 through which the flexible piping is passed.

Embodiment 2 FIGS. 3 and 4 show another embodiment of the present invention. This embodiment is applied when the heat insulating material 32 is stuck on the lower surface of the floor 10. When the heat insulating material 32 is stuck on the lower surface of the floor 10, when a hole is made in the floor 10, the heat insulating material may be lost around the hole and the heat insulating property may be deteriorated. Therefore, in this embodiment, the plate-like holding member 20 formed by laminating and integrating the heat insulating material 36 on the rigid plate material 34 is used. If such a plate-like holding member 20 is adhered and fixed to the lower surface of the heat insulating material 32 on the floor 10 side by the adhesive layer 28, even if the heat insulating material 32 on the floor 10 side is somewhat missing, the heat insulation on the plate-like holding member 20 side is obtained. The material 32 can ensure heat insulation.

  In addition, although it is preferable to use foamed polyethylene etc. as the heat insulating material 36 of the plate-shaped holding member 20, if the heat insulating material with rigidity is used, the plate-shaped holding member 20 whole can also be comprised with a heat insulating material.
