2. Description of the Related Art Conventionally, in a general wooden house or an apartment house, pipes are sometimes provided under clean water and under a floor plate at a place where water is used, such as a washing machine, a washroom, and a kitchen. A hole was formed, a conduit was passed through the hole, and a gap between the hole on the floor plate and the conduit was closed with a rubber packing or caulking material. According to this conventional method, there is a drawback that when a load is applied to the vicinity of the hole through which the conduit passes, the floor plate surface is curved, and in some cases, the conduit is damaged or the conduit is displaced from the fixed position.

In order to eliminate the above-mentioned drawbacks, a through hole is previously formed in the floor plate surface, an elbow type joint is fixed in the through hole, and a metal conduit is provided on the floor plate surface, and a metal conduit is provided below the floor plate surface. A method of connecting flexible resin pipes has been proposed and adopted, but the work of aligning and fixing the elbow joint at a position to fix the joint requires complicated and high skill. Further, the drawback that the floor plate surface is curved when a load is applied to the vicinity of the conduit has not been solved yet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.
In the present invention, the elbow type joint is generally an elbow having a 90-degree bend, but is not limited to this type. The material of the elbow joint is generally a metal. At one end of the elbow type joint, it is necessary that a female screw is formed on the inner peripheral surface and a male screw is formed on the outer peripheral surface. A male screw of a water faucet is screwed into the female screw on the inner peripheral surface at one end, and a flange is screwed on the male screw on the outer peripheral surface.
The flange is secured to a metal frame at one end of the elbow joint. A fixing ring is further screwed to one end of the elbow type joint via a packing, a washer or the like.
When installing on the floor surface, remove the packing, washer, fixing ring, etc. from one end, insert it into the through hole previously drilled on the floor plate surface, and screw the packing, washer, fixing ring, etc. again .

The other end of the elbow-type joint is formed with an inner core portion having an uneven portion engraved on the outer peripheral surface. A flexible resin tube is fitted on the inner core portion, and the inner core portion has a flexible resin tube. The connection is fixed by pressing the inner core portion from the outside of the resin tube with a pressing ring or the like. Examples of the flexible resin include crosslinked polyethylene and polybutene.

The above-mentioned elbow joint is fixed by inserting one end into a through hole provided in a predetermined position in a metal frame having a wide U-shaped cross section cut in parallel to the length direction. The metal frame has an elbow-type joint fixed to it and serves as a member for attaching a water pipe in a dwelling unit.Since the metal frame reinforces the floor panel surface under the load of the water pipe, the floor panel surface must be separated There is no need to reinforce with a reinforcing member. The metal frame has a U-shaped cross section cut in parallel to the length direction, and may be formed of a single component. The cross section cut in parallel to the length direction has an L shape. A combination of at least two frames is preferred. An ordinary bolt hole is drilled in one of the legs (long pieces) of the two L-shaped frames, and a slide hole is drilled in the other long piece, so that the base surface (for example, slab surface, etc.) and the floor plate surface It is more preferable that the length of the foot of the L-shaped frame can be adjusted according to the size of the interval.

[0010] A through hole is previously provided at an appropriate position of the metal frame. Here, the appropriate position means one end of a U-shape. When two L-shaped frames are combined,
It refers to the head (short piece) of one L-shaped frame. A through-hole is provided in this appropriate place, and the above-mentioned one end of the elbow-type joint is inserted into this hole, and is fixed to a metal frame in a state of being protruded to constitute a member for attaching a water supply pipe in a dwelling unit.

In order to fix the elbow-type joint to the metal frame, one end of the elbow-type joint is inserted into a through hole provided in advance in the metal frame, and is fixed to the metal frame in a state where it protrudes. By moving the position of the elbow type joint on the male screw on the flange, the length of the protruding portion to be protruded can be adjusted. By adjusting the length of the protruding portion, it is possible to easily cope with a change in the thickness of the floor plate surface at the time of construction. In order to fix the flange at an appropriate position on a male screw carved on the outside of one end of the elbow joint, a method is preferable in which a screw is abutted against a male screw to stop the screw, but it can also be fixed by welding.

The following procedure is used to attach the water pipe installation member in the dwelling unit to the floor plate surface. First, a flexible resin pipe is externally fitted to the outer peripheral surface of the inner core portion of the elbow-type joint constituting the member for attaching a water supply pipe in a dwelling unit, and is fixed with a holding ring or the like. Next, the protruding portion projecting from the through hole of the metal frame is inserted into a through hole previously drilled at a position where the water pipe in the dwelling unit is to be mounted on the floor plate surface from the lower surface of the floor plate surface, and the protrusion protruding from the floor plate surface. A packing and / or a washer is interposed in the portion, and a fixing ring is screwed in from the surface side of the floor plate surface and tightened. Since the fixing ring sandwiches the floor plate surface from the front surface side of the floor plate surface and the metal frame of the water pipe installation member in the dwelling unit from the back surface side of the floor plate surface, it can be firmly and reliably fixed. When a packing and / or a washer is interposed in the protruding portion, even if water is applied to the attachment portion of the water supply pipe in the dwelling unit, it can be prevented from leaking to the lower surface side of the floor plate surface, which is preferable.

Next, the male screw of the water supply pipe in the dwelling unit is screwed into the female screw carved on the inner peripheral surface of the projecting portion of the elbow type joint projecting from the surface of the floor plate. Thereby, the water supply pipe in the dwelling unit can be attached to a predetermined position on the floor plate surface, and the construction is completed. When the fixing ring is covered with a cover from the front side of the floorboard surface, the appearance can be improved.

The flexible resin tube to be connected and fixed to the inner core portion of the elbow joint is inserted in advance into the sheath tube in order to prevent the surface from being scratched or accidentally nailed. Is preferred. The sheath tube preferably has a bellows tube structure made of resin. Further, a foamed resin sheet may be interposed in the flexible resin tube for the purpose of silencing the water hammer sound.
