Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a displacement absorbing waterproofing mechanism for piping that penetrates walls, floors, etc. When constructing a new wall, floor, etc. through which electric wire cables, water pipes, gas pipes, etc. will pass through, and passing the various piping described above, first install sleeve pipes in the holes through which the various piping described above will penetrate, and then insert sleeve pipes into the walls and floors. After constructing the sleeve pipe, a F9 length pipe is passed through the sleeve pipe, but when penetrating the sleeve pipe, due to the nature of the pipe, airtightness and waterproofness are taken into consideration, and the pipe may be damaged due to various vibrations caused by earthquakes or the like. In order to prevent damage to the pipes, walls, floors, etc. due to contact with the pipes, consideration should be given to vibration isolation properties, and a series of treatments that can also cope with the displacement of the pipes is required.

Conventionally, there are various methods for this type of treatment, such as the waterproof mortar method, yarn + lead caulking method, elastic sealing method, and link sealing method, but these have various drawbacks and are not completely desirable. It is.

For example, the waterproof mortar method and elastic sealing method are not completely waterproof, the link seal method is expensive and inferior in terms of displacement absorption, and the yarn + lead caulking method requires a large amount of work space, tools, and skilled technology. There was a drawback.

This invention eliminates all the drawbacks of the conventional construction methods mentioned above, and has excellent vibration isolation and displacement absorbing properties as well as waterproofness and airtightness, and can be assembled using the dry method. Therefore, it is an object of the present invention to provide a displacement absorbing and waterproofing mechanism for through-piping that does not take much time, can be assembled extremely easily and quickly with a small number of members, and is inexpensive and requires no skill.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is a longitudinal end view without showing the construction process of this invention;
1 is a concrete frame that constitutes walls, floors, etc., and 2 is a tubular cast sleeve pipe, which has a brim-shaped concrete adhesion member 3 at the center of the outer periphery in order to round out the adhesion and waterproofness. There is. Furthermore, this driving sleeve pipe 2 has a temporary frame mounting piece 4 having a nail driving hole 5 joined in advance to one end of the Olu which is the inner side, that is, the indoor side. A mounting piece 7 having a nut hole 6 for mounting rings is preliminarily joined to the other end of 2, and nails are attached to the mounting piece 7 so that it can be mounted regardless of the order in which the temporary frame materials are erected. A driving hole 8 is bored. When facing the concrete frame 1, the driving sleeve pipe 2 is supported by a temporary frame (not shown) by the nail driving hole 1 or 8, and is positioned at a fixed location 19r of the concrete frame 1. .

On the outer surface of the mounting piece of the driving sleeve pipe 2 from which the temporary frame has been removed, an annular packing is used on the side closer to the concrete frame 1, an L-shaped receiving ring 11 with an L-shaped cross section, and a cylindrical heat-shrinkable resin part 12. One end 13a1 of resin bellows ■3 integrated with
4 in sequence, and the ends of an appropriate number of tightening bolts 15 at regular intervals along the circumference of this retaining ring I4 are passed through the holes of each part described in 2 above, and then inserted into the nut holes 6 of the mounting piece 7. Screw it into place and secure each of the above members. Then, insert piping 9 into the center hole of each of these parts and into the driving sleeve pipe 2)
lzu. Note that this piping 9 is supported by another object (not shown).

Next, the position where the heat-shrinkable resin part 12 is to be shrunk is determined, and as shown in FIG. Periphery and density;
t-'tU.

As described above, the waterproofing mechanism according to the present invention uses a small number of members, does not use special tool sounds, and does not require any special techniques, so anyone can easily carry out the processing work.

Also, it doesn't take up much space and can be used to store structures? ]1. It is possible to work in narrow spaces.

In addition, the member that is joined to the heat-shrinkable resin part 12 for waterproof contact is the resin bellows 13, so it is flexible.
It can be set arbitrarily within the allowable expansion range of , therefore, it can follow even a large misalignment of the piping 9, and has excellent displacement flexibility. Moreover, this resin bellows 13 has excellent vibration isolation, and can protect the pipes 9 and the concrete frame 1 from being affected by walls or floors, even during earthquakes and uneven settlements.

Furthermore, unlike the conventional waterproof mortar method, water is not required, and the treatment can be carried out using a so-called dry method, so it is also applicable to walls and floors made of materials that dislike moisture.

Moreover, regarding the important waterproofing and airtightness, the adhesion on the piping 9 side is strong due to the contraction of the heat-shrinkable resin part I2, and the structure 1 side is also tightened through the packing material 10.
It is fixed at 15, so it is almost perfect.

In addition, considering the retention of the resin material after the heat shrinkage is completed, heat shrink film 24F+! is used as shown in Figure 3. If the fat part 12 is folded back toward the inside of the driving slag tube 2, that is, towards the indoor direction, and brought into close contact, the appearance will be clearer, and it can be protected by a sealing plate, which will be described later, and the effect will be the same.

Furthermore, as shown in FIG. 1, it goes without saying that an appropriately shaped elastic body 16 having so-called "play" may be used behind the bellows 13 made of resin.

By the way, all walls, floors, etc. are covered with concrete framework 1 (in some cases, mortar 19 or various paints are applied to the surface).This invention also applies to such mortar finishing etc. It is something that can be dealt with.

That is, before the pipe 9 is inserted, as shown in Fig. S, a curing sleeve 18 having a spring J7 at an appropriate position on the inner circumference is supported at the end of the driving sleeve pipe 2, and the outer surface of the mounting piece 7 is temporarily closed. Mortaring operations can be easily carried out while securing the interrogation area D for each abductee.

Even if the above-mentioned curing sleeve J8 is not used, as shown in FIG.
is the outer peripheral edge side of the channel groove receiving ring side.

A is used to make the mortar finish easier.

In addition, the above-mentioned 7-ring plate (61) and a retention cover for protecting fats can be supported on the body surface by springs or the like, or on the piping body, as required, in accordance with the curing sleeve 18.

Further, in the above embodiments, the frame was made of concrete, but the present invention can be implemented even if the frame is made of iron plates or other materials, and the same function can of course be achieved. In the above embodiment, the heat-shrinkable resin part 12 and the bellows l:3 made of handle fat are made by joining the side materials together, but the invention is not limited to this. good.

In addition, the bellows 13 or the elastic body 16 made of resin in the above embodiments may be made of a material or shaped body that can be expanded or contracted, and the cylindrical body herein refers to a cylinder, a square tube, a cone, a pyramid, a bellows shape, etc. It suffices if it has a shape that covers it.

Furthermore, connect the periphery of one end of this elastic body! The member that is brought into close contact with the J-1 body side is not limited to the members of the above embodiments, but may be made of any suitable member.
