Description

[Detailed Description of the Invention] 4 (Field of Industrial Application) The present invention provides a drainage device with a positioning fixture, which is a combination of a drainage device such as a drain trap, a drain fitting, a roof drain, or a line opening fitting, and a positioning fixture thereof. In detail, when constructing the floor, veranda, flat roof, or wall of a building, the drainage equipment is fixed on a temporary frame in advance, concrete is poured, and this is directly buried in the concrete. This invention relates to a drainage device with a positioning fixture that is effective when used in construction methods.

(Prior Art) Conventionally, the following are typical methods for positioning and fixing drainage equipment used in such construction methods.

First, as shown in Fig. 8, a nail d is driven into the temporary frame C through a nail hole provided in a predetermined part of the fixture a, a drainage device e is placed over the top of the fixture a, and the bolt f and Something that is fixed via a presser plate q.

Second, as shown in FIG.
Fix it on the temporary frame j by driving a nail k into the temporary frame j through the nail hole i penetrated in the frame j, and connect the drain pipe of the drain device 1 to the male screw threaded on the outer circumferential surface of the fixture. A device that fixes this by screwing together a female screw.

Thirdly, as shown in Fig. 10, by driving a nail q into the temporary frame p through a nail hole O penetrated through the lower flange of the drain device n, the drain device n can be attached via a fixing device or the like. It is fixed directly onto the temporary frame p.

(Problems to be Solved by the Invention) However, the first and second methods described above are only intended for positioning and fixing drainage equipment;
Therefore, the mount a or the fixture itself does not allow drainage to flow through it!
It has neither a tubular structure to obtain nor a structure for connecting a drain pipe at the bottom. Therefore, in the case of using the fixture a or the fixing tool, there is a disadvantage in that the complicated work of removing it from the drainage equipment is required during piping work after the concrete m is placed, and the work efficiency is reduced.

In addition, although the third method described above does not have such a drawback, at the stage when the drain device n is temporarily fixed on the temporary frame p, a request arises to replace the drain device n with another drain device. In this case, in order to meet such a request, it is necessary to remove the drainage fixture n by placing the nail q above the temporary frame ρ, and then position the other drainage fixture against the temporary frame p and nail it in place. However, there was a drawback that the above requirements could not be met quickly.

SUMMARY OF THE INVENTION Therefore, the present invention provides a drainage device with a positioning fixture, which is a combination of a drainage device and its positioning fixture, wherein the positioning fixture itself has a structure that allows drainage to flow, and is directly connected to a drain pipe. It is an object of the present invention to provide a drainage fixture with a positioning fixture, which allows the drainage fixture to be fixed temporarily on a temporary frame, and allows the drainage fixture combined with this to be quickly replaced with another drainage fixture while the positioning fixture is temporarily fixed on a temporary frame. .

(Means for Solving the Problems) In order to solve the above problems, a drainage device with a positioning fixture according to the present invention is fixed to the drainage device and a temporary frame for concrete pouring by a nailing method. A drainage device with a positioning fixture connected to a positioning fixture via a removable connecting part, the positioning fixture having a tubular shape and having an opening at one end with the connecting part,
The narrow end opening is also provided with a pipe connection part for connecting a drain pipe, and the positioning fixture is further provided with an appropriate number of needle holes.

(Function) When the positioning fixture of the drainage fixture with positioning fixture according to the present invention is fixed onto a temporary frame for concrete pouring by nailing it through the nail hole, the drainage fixture is also positioned and fixed. Ru.

In response to a request to replace the drainage fixture with another one, the positioning fixture remains fixed, the drain fixture connected to it is removed, and the other υ1 water fixture is connected (J
good.

After that, concrete is placed on the temporary frame, and after assimilation, the temporary frame is removed, and a drain pipe is connected to the pipe connection part of the positioning fixture. A flow path is formed from the drainage device to the drain pipe via the fixture.

(Example) Next, an example of the present invention will be described based on FIGS. 1 to 7. A drainage fixture with a positioning fixture according to the present example 1
The positioning fixture 2 is formed into a tubular shape with a communication path 3 in the center, and a drainage fixture 5 is provided on the outer peripheral surface of a cylindrical connecting part 4 that projects upward from the upper part of the positioning fixture 2. A male thread 7 corresponding to the female thread 6 is formed on the inner periphery of the lower part, and by screwing this male thread 7 into the female thread 6, the positioning fixture 2 and the drainage device 5 are connected. ing.

Further, an inner circumferential portion of the lower part of the positioning fixture 2 is provided with an inner insertion portion 9 having an inner diameter into which the drain pipe 8 on the F flow side can be inserted, as shown in FIGS. A screw hole 12 is formed in the peripheral edge of the portion 9 to be screwed into a bolt 11 for tightening a presser flange 10 for fixing the drain pipe 8 to the inner insertion portion 9.

Roughly, as shown in FIGS. 2 and 3, a ring-shaped flange 15 is integrally formed on the outer periphery of the upper end of the positioning fixture 2 via a rib 14, and the outer periphery of the flange 15 is An inclined surface part 16 is provided around the periphery of the inclined surface part 16 which is inclined at a predetermined angle with respect to the horizontal plane, and an appropriate number of nail holes 17 are provided from this inclined surface part 16 toward the lower surface of the flange at an arbitrary angle with respect to the axial direction of the tubular part of the positioning fixture 2. It is installed through.

The present embodiment is constructed as described above, and as shown in FIG. It is fixed on the temporary frame 20 and concrete 21 is poured. or,
As shown in FIG. 4, a waterproof member 23 is laid across the upper surface of the concrete 21, cinder concrete and poured mortar 24 are cast thereon, and a floor finishing material 25 is laid.

On the other hand, after removing the temporary frame 20 from the concrete 21, cutting and removing the tip of the nail 19 protruding from the positioning fixture 2, and inserting the drain pipe 8 into the inner insertion part 9 of the positioning fixture 2, A backing 13 is interposed between the inner circumferential surface of the inner circumferential surface of the inner circumferential portion 9 and the outer circumferential surface of the drain pipe 8, and the bolt 11 for tightening the presser flange 10 attached to the drain pipe 8 is positioned on the inner circumferential surface of the inner circumferential portion 9 of the fixture 2. The drain pipe 8 is fixed by screwing it into the screw hole 12 at the periphery of the bottom end opening.

Although the wall thickness of drain pipes varies considerably depending on the type of pipe, in this case, if the so-called nominal dimensions of the drain pipe are the same, the outer diameter is approximately the same in most cases.
Different types of drain pipes 8 can be connected to the inner insertion part 9.

In addition, when connecting downstream piping to drainage equipment that is generally buried in the floor concrete slab of a reinforced concrete 1/1 building, the work is done on the ceiling of the floor below the floor concrete slab, and if the work is done upside down, the posture will be affected. This method requires the use of relatively large tools such as a pipe wrench, which requires a large amount of work, and requires considerable labor. However, the drainage fixture 1 with positioning fixture according to this embodiment
When connecting the drain pipe 8 to the drain pipe 8, there is no need to handle a large tool in a supine position, making the work easier and improving work efficiency.

However, in the first, second, and third conventional methods, nails d and q are installed vertically through the nails d and q for fixing the mount a, fixture, and drainage device n to the temporary frames C1j and p, respectively. As the nail holes, i, and o are guided and driven into the temporary frames c, j, and p almost perpendicularly, the drainage fixtures e, N, and n may be subjected to eccentric loads due to workers stepping on them, etc. In this case, the opposite part of the part that received the eccentric load will tighten the nails d and k due to the action of the lever.
.

There were cases where it was lifted with q becoming loose or missing. When concrete m is placed in this state, concrete m is poured into the void formed in the lifted part.
may flow in and solidify, and as a result, drainage equipment e,,Q'
, n is fixed at an angle with respect to the horizontal plane,
There was a drawback that caused significant harm to later piping work.

However, in this embodiment, when the drainage device connected to the positioning fixture is subjected to an eccentric load, even if a moment in the lifting direction due to a lever action is applied to the part opposite to the part that received the eccentric load, the temporary frame will not be able to move. On the other hand, since the direction in which the nail fixing the positioning fixture is pulled out is different from the direction of the moment, the nail is less likely to loosen or fall out, thus preventing the positioning fixture and the drainage device from being lifted.

In this embodiment, a drain trap is shown as the drain device 5, but other examples include the roof drain shown in FIGS. 5 and 6, the floor cleaning opening fitting shown in FIG. 7, and in special cases. Although not shown, it may be a so-called horizontal roof drain buried in the horizontal direction, and the type of drainage equipment is not limited in any way.

In addition, as for the configuration of the connecting part between the positioning fixture 2 and the drainage fixture 5, in addition to the case where the male thread 7 and the female thread 6 are threaded, an insertion part is provided in the lower inner circumference of the drainage fixture to form the positioning fixture. A method in which the upper connecting pipe part of the drainage device is inserted into the inner part.The connection is removable, such as one in which the lower part of the drainage device and the upper part of the positioning fixture are connected by flanges provided respectively. .

(Effects) The drainage fixture with a positioning fixture according to the present invention can improve work efficiency by eliminating the need to remove the positioning fixture from the drainage fixture during piping work after concrete pouring work, and can improve work efficiency after temporary fixing. This has the effect of improving responsiveness to replacing drainage equipment.
