Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plumbing method and a socket and a pipe used in the method, and more particularly to a plumbing method and a pipe method prior to embedding a water distribution pipe in a solid foundation made of reinforced concrete. For sockets and tubes used for

[0002]

2. Description of the Related Art Conventionally, in this type of piping construction, first, an elbow or a horizontal drawing pipe is connected and fixed to a socket in advance, and a tape or the like is attached to an opening to prevent earth and sand from entering.
The work is performed while strongly pressing the socket tip against the surface of the surrounding wooden frame to create a solid foundation.

[0003] This construction is often carried out in parallel with the reinforcing bars, and the pipes are strongly tied to the reinforcing bars with wires or the like, so that the rising pipes are vertical and the socket ends do not separate from the wooden frame surface. It is done as follows.

[0004]

However, according to the conventional construction method, two or more workers are required at first, and since the method relies on a reinforcing bar, the socket ends are hardly bound by a wire or the like, so that the end of the socket is made of wood. If it is separated from the frame surface, and if it is not strongly tied up, the reinforcement will be stepped on during the reinforcement arrangement work, and the fresh concrete will be driven in, the piping will move, and the subsequent internal piping will be extremely difficult. Due to time and material limitations, if the socket end faces become invisible due to the movement of the piping, the concrete must be broken and the socket end must be found, but the socket may be broken during the work.

[0005] Further, since the work is tied to a reinforcing bar, it is difficult to construct a slope for natural flow of water. In some cases, a reinforcing bar cut to an appropriate length is further inserted and fixed, and piping is connected to the reinforcing bar. However, it is almost impossible to obtain a delicate gradient from the approaching pipe due to time constraints.

[0006] Further, by binding with a wire or the like, the rising pipes are inclined to a considerable extent after placing the ready-mixed concrete, and the subsequent work is often troublesome, and the appearance of the client is poor and the technical level is suspected. It can happen. And, in order to make this slanted pipe vertical and horizontal pipe, many joints will be used,
It often causes poor flow after use and clogging of pipes.

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made by focusing on the conventional actual situation and problems, and it has been made possible to solve such problems and make it possible for a single person to execute the method without relying on rebar.
A plumbing method and its construction method that enables the construction to be performed accurately within the limited time and without relying on rebars to accurately take and maintain the arrangement direction in the sense including the gradient of each individual and multiple pipes The purpose is to provide sockets and tubes used in the construction method.

[0008]

In order to achieve this object, the present invention is to fix a socket having a mounting flange at an end thereof to an enclosure wooden frame for forming a solid foundation made of reinforced concrete by the mounting flange. Characterized in that, after that, the piping is bonded to the socket described above,
At one end, a mounting flange which is fixed to the surrounding wooden frame is formed, and the mounting flange has a lower portion having a greater width than an upper portion, and at least one or more protrusions project in a body direction. A swelling portion having a vertically extending through-hole formed at a symmetrical position on the outer surface, the swelling portion having a detachable reinforcing ring member having a cutout portion fitted with the projection portion; A screw mounting hole from the outer surface of the pipe to the through hole is formed, wherein the pipe is connected to the socket, at least one or more bulges are formed on the outer surface thereof, The bulging portion has upper and lower through holes formed therein, and a screw mounting hole extending from the outer surface of the bulging portion to the through hole is formed.

[0009]

With the above construction, the work of the piping can be performed by a single person, and even within a limited time, the positioning and direction of the piping including the gradients of the individual and plural pipes can be accurately performed. Therefore, there is no possibility that earth and sand may flow into the pipe.

Next, preferred embodiments of the present invention will be described with reference to the drawings. 1 is a side view showing a main part of a socket embodying the present invention, FIG. 2 is a front view of the same, FIG. 3 is a front view of a ring member, FIG. 4 is a plan view of the same, and FIG. , FIG. 6 is a perspective view of the tube,
FIG. 7 is a plan view showing an attached state, and FIG. 8 is a perspective view showing a used state.

In these figures, reference numeral 1 denotes a socket body embodying the present invention. The socket body 1 has a cylindrical shape, and has an opening edge at one end, for example, as shown in FIG. 5, for abutting and fixing to a surrounding wooden frame A for forming a solid foundation made of reinforced concrete. The ring flange 2 is formed integrally.

This ring flange 2 has a socket body 1
A plurality (eight in this example) of nail punching holes 3, 3,... Are drilled radially to facilitate positioning and adjustment for mounting of the socket body. A thick portion 4 for increasing the strength is formed at the boundary between the two. Although the thick portion 4 is formed in an annular shape in the present embodiment, it may be formed partially at a predetermined pitch.

The above-mentioned ring flange 2 is provided with a wooden frame A.
The thickness of the lower part is made larger than that of the upper part so that the gradient can be obtained automatically and stably so that the water will flow naturally later when it is fixed by abutment. And, in order to prevent the vertical error from occurring, the socket main body 1 may be provided with a display indicating the upper and lower sides. In the drawings, reference numerals 5 and 5 denote projections formed in parallel with the end of the ring flange 2 in the direction of the cylinder, and serve to position a ring member to be described later.

On the other hand, reference numeral 6 in the drawing denotes a protection cap made of polypropylene, which is fitted to the end of the socket body 1 provided with the ring flange 2 to prevent intrusion of earth and sand. The protective cap 6 has a drop lid shape with a flange 6a formed on the outer edge, and is received by an annular concave portion 2a formed on the inner diameter edge of the ring flange 2. The reason why the protective cap 6 is formed of polypropylene is that even if an adhesive substance such as cement adheres, its adhesive integrity is small.

In FIG. 1, reference numeral 7 denotes a ring member for reinforcement.
An insertion hole 8 having a diameter that matches the outer diameter of the cylindrical portion is formed, and the entire diameter matches the ring flange 2.

The ring member 7 is provided with notches 9 and 9 formed in a dovetail shape at positions opposed to each other at a pitch of 180 degrees.
With the cutouts 9 and 9 positioned vertically, the ring flange 2 is fitted and fixed to the projections 5 and 5. A recess 10 is formed along the insertion hole 8 to allow the thick portion 4 to escape during the fitting.

Further, the ring member 7 is provided with cylindrical projections 11, 11,... At positions corresponding to the nail holes 3, 3,.
Are formed to penetrate through the holes 1, 11, and communicate with the nail holes 3.
2, 12,... Are used to prevent the nail from coming off.
are slightly thinner, and the columnar projections 11, 11 ... also have a buffering function when nailing and fixing.

Instruction lines 13, 13 for facilitating centering and mounting operations are provided on the outer surface of the ring member 7 in horizontal and vertical directions.

The socket body 1 is fixed to the wooden frame A with nails as shown in FIG. 5, and the pipe B is bonded and joined. At this time, the lower part of the ring flange 2 is thickened. It is possible to automatically obtain the gradient as shown.

Next, in the figure, reference numeral 14 denotes a pipe which can also be used as the socket body 1. The pipe 14 has bulging portions 15 and 15 integrally formed on the outer surface thereof so as to face each other. Upper and lower through holes 16 having a direction intersecting at right angles to the axial direction of the pipe 14 are formed in the bulging portion 15, and the upper and lower through holes 16 have a reinforcing bar having an appropriate length separately from reinforcing bars. C is to be inserted. In addition, it is assumed that a thread may be formed on the reinforcing bar C as necessary, and positioning may be performed by the nut 17. The thickness of the bulging portion 15 allows the rotation of the nut 17, and furthermore, the strength and the vertical In order to maintain the directionality, it is desirable that the height of the bulging portion 15 be as large as possible.

Further, a screw hole 18 communicating from the outer surface to the above-mentioned upper and lower through-holes 16 is formed in the above-mentioned bulging portion 15, and a screw 19 having a sharp tip is screwed into the screw hole 18 so that the screw hole 18 is screwed. The reinforcing bar C can be fixed at the tip of the screw 19 while adjusting the height.

Further, when applied to the elbow pipe 20, the bulging portions 15a, 15a,... Are provided at three places on the peripheral wall of the rising portion 20a, so that further stability can be obtained.

With this configuration, the pipe 14 and the elbow pipe 20 can be positioned not only by pressing against the wooden frame A with the support force of the reinforcing bar C but also at a position distant from the wooden frame A. In particular, screws 19 are used. Then, in addition to height adjustment,
The effect of preventing lifting is also obtained. In particular, in the middle part of the pipe, the reinforcing bar C also acts as a spacer to the ground surface in addition to positioning, and the reinforcing bar C inserted into the upper and lower through holes 16 is driven into the ground. It can be fixed at an arbitrary place, and the upper and lower through holes 16 have a slight margin to be fixed with the screw 19 between the upper and lower through-holes C, so that a delicate gradient can be taken.

Further, the pipe 14 and the elbow pipe 20 provided with the bulging portions 15 and 15a can be used also for a ceiling suspension pipe, and can be operated with a crown rod, so that it is very efficient. If the nut is clamped from below and above to the crown rod passed through the upper and lower through holes 16, a firm fixation can be obtained, and if it is fixed at the joint portion, the weight of the suspension pipe can be greatly increased.

[0025]

The piping method according to the present invention and the socket and pipe used in the method are constructed as described above. Therefore, the construction can be done by a single person, and within a limited time, positioning including the gradient, directionality can be taken accurately, the appearance becomes good, and the internal piping afterwards Very easy to do. Further, this work does not require any special skill, and the efficiency of the work can be improved and the work can be made very easy.
