Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dwelling unit water pipe attaching member and a method for installing the same. More specifically, the present invention relates to a dwelling unit water pipe attaching member that can easily attach a dwelling unit water supply pipe to a floor surface, and a mounting method of the dwelling unit water supply pipe attaching member.
[0002]
[Prior art]
Conventionally, in general wooden houses and apartment houses, pipes are provided under the floor and floor water in places where water is used, such as washing machines, washrooms, and kitchens. A conduit was passed through this hole, and the space between the hole on the floor board surface and the conduit was sealed with rubber packing or caulking material. According to this conventional method, when a load is applied in the vicinity of the hole through the conduit, the floor board surface is curved, and in some cases, the conduit is damaged, or the conduit is broken from the fixed position.
[0003]
For the purpose of eliminating the above disadvantages, a through hole is previously drilled in the floor plate surface, an elbow joint is fixed to the through hole, a metal conduit is provided on the floor plate surface, and a flexible resin is provided below the floor plate surface. A method of connecting pipes has been proposed and adopted, but the work of aligning and fixing the elbow joint to the position where it is fixed requires complicated and highly skilled skills. Moreover, the fault that the floor board surface curves when the load is applied in the vicinity of the conduit has not been solved.
[0004]

[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
In the present invention, the elbow-type joint is generally a 90-degree bend elbow, but is not limited to this type. The material of the elbow joint is generally metal. One end of the elbow joint needs to have an internal thread engraved on the inner peripheral surface and an external thread engraved on the outer peripheral surface. The male screw of the faucet is screwed into the female screw on the inner peripheral surface of the one end, and the flange is screwed into the male screw on the outer peripheral surface. The flange is fixed to the metal frame at an appropriate position on one end of the elbow joint. A fixing ring is further screwed into one end of the elbow joint through a packing, a washer and 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 in the floor plate surface, and screw the packing, washer, fixing ring, etc. again. .
[0008]
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, and a flexible resin tube is fitted on the inner core portion, and the flexible resin tube It is configured to be pressed and connected to the inner core portion by a pressing ring or the like from the outside. Examples of the flexible resin include cross-linked polyethylene and polybutene.
[0009]
The elbow joint is fixed by inserting one end into a through-hole provided in advance in a metal frame having a wide cross section cut in parallel to the length direction and having a U-shape. The metal frame is used to fix the elbow joint to the housing water pipe attachment member, and the metal frame reinforces the floor board surface under the load of the water pipe. 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 composed of a single component, but the cross section cut in parallel to the length direction has an L shape. A combination of at least two frames is preferred. A normal bolt hole is drilled in one of the leg portions (long pieces) of the two L-shaped frames, and a slide hole is drilled in the other long piece, respectively, and a base surface (for example, a slab surface) and a floor board surface, It is more preferable to adjust the length of the leg of the L-shaped frame according to the size of the interval.
[0010]
A through-hole is provided in advance in a proper position of the metal frame. Here, the proper position refers to one end of the U-shape. When it is a combination of two L-shaped frames, it means the head (short piece) of one L-shaped frame. A through hole is provided at an appropriate place, and the above-mentioned one end of the elbow joint is inserted into and protruded from the hole, and is fixed to the metal frame to constitute a dwelling unit water pipe attaching member.
[0011]
In order to fix the elbow joint to the metal frame, one end of the elbow joint is inserted into a through hole provided in the metal frame in advance and fixed to the metal frame. By moving the position of the elbow joint on the male screw, the flange can adjust the length of the protruding portion to be protruded. By adjusting the length of the protruding portion, it is possible to easily cope with changes in the thickness of the floor board surface during construction. In order to fix the flange at an appropriate position on the male screw engraved on the outer side of one end of the elbow joint, a method of stopping the screw by abutting on the male screw side is preferable, but it can also be fixed by welding.
[0012]
The following procedure is used to install and install the water pipe mounting member in the dwelling unit on the floor board surface. First, a flexible resin pipe is fitted on the outer peripheral surface of the inner core portion of the elbow joint constituting the dwelling unit water supply pipe mounting member, and fixed with a pressing ring or the like. Next, the protruding part protruding from the through hole of the metal frame is inserted from the lower surface of the floor board surface into the through hole previously drilled at the position where the water pipe in the dwelling unit on the floor board surface is installed, and the protruding part protruding from the floor board surface is inserted. A packing and / or a washer is interposed in the part, and a fixing ring is screwed 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 dwelling unit water pipe attaching member 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, it is possible to prevent leakage to the lower surface side of the floor plate surface even if water is attached to the mounting portion of the dwelling unit water supply pipe.
[0013]
Next, the male screw of the water pipe in the dwelling unit is screwed into the female screw carved on the inner peripheral surface of the protruding portion of the protruding elbow joint on the surface side of the floor plate surface. Thereby, the dwelling unit water supply pipe can be attached to the predetermined position of the floor board surface, and construction is completed. When the fixing ring is covered with a cover from the surface side of the floor plate surface, the aesthetic appearance can be improved.
[0014]
The flexible resin tube connected and fixed to the inner core portion of the elbow joint is preferably inserted in advance into the sheath tube for the purpose of preventing the surface from being scratched or accidentally nailing. The sheath tube is preferably a resin bellows tube structure. Furthermore, a foamed resin sheet can be interposed in the sheath of the flexible resin tube in order to mute the water hammer sound.
[0015]
