Description

  The present invention relates to a waterproof piping device equipped in a piping facility penetrating a slab of a housing in a building, particularly a building corresponding to a 200-year house vision or the like.

  For example, in order to facilitate drainage in apartment buildings, a drainage stand pipe that penetrates the rooftop is installed and intake air is taken in from the rooftop, but the penetrating part needs waterproofing to penetrate the rooftop slab. Become. As for the construction method of this part, conventionally, a structure in which the housing and the equipment are integrated has been generally taken. On the other hand, the policy of “200-year Housing Vision” has recently been disseminated, in which the structural frame (skeleton) and interior / equipment (infill) have been separated, and the skeleton has durability and earthquake resistance, It is shown as performance to be secured that variability is secured for infill. Under such super long-term housing guidelines, even when equipment (infill) is replaced due to deterioration over time, construction that damages the skeleton that is not scheduled for replacement must be avoided.

  On the other hand, in the conventional construction method, when installing a drainage vertical pipe penetrating the roof slab, as shown in FIG. 6, the ventilation pipe a has a structure fixed integrally with the slab b. The upper end portion of the ventilation pipe a is connected to the base portion of the apparatus main body c installed above, and the vent metal d is attached to the upper end of the apparatus main body c. In this structure, since the inside e of the apparatus main body c is in contact with the ventilation, it is regarded as a part of the ventilation pipe a and renewal work is required. Construction is required in which the slab b is broken using a pulverizer or the like, or the press mortar m or the heat insulating material h covering the waterproof layer f on the roof is peeled off. However, as shown in Japanese Patent Application Laid-Open No. 2006-124981, for example, when this type of roof slab penetration structure is seen, there are almost examples in which it is fixed to the slab of the drainage pipe.

JP 2006-124981 A

  The present invention has been made paying attention to the above points, and the problem is that the structure of the equipment can be eliminated by making the structure (infill) and the equipment (infill) separated from each other without breaking the slab of the equipment. It is to provide a waterproof piping device in a building capable of executing renewal work. Moreover, the other subject of this invention is providing the thing which can perform the renewal construction of an installation with the minimum construction period and construction cost in the waterproof piping apparatus in a building.

  In order to solve the above-mentioned problems, the present invention provides a waterproof piping device equipped in a piping facility that penetrates a slab of a housing in a building, a pipe that does not substantially have a joint structure, and an outer diameter of the pipe. An apparatus main body having an inner diameter formed to be slightly larger than the inner diameter and having the above-mentioned inner diameter through which the pipe is passed is installed to prevent moisture from entering the apparatus main body from the outside of the housing. An outer waterproof means and an inner waterproof means for preventing moisture from entering the inside of the housing from the inside of the apparatus main body, and the pipe and the apparatus main body are coupled at the outer waterproof means and the inner waterproof means. The means of having the configuration as described above is taken.

  In the apparatus of the present invention, for example, as described above, a case where a drainage pipe penetrating the roof slab is installed is taken as one typical example. When considering drainage in each room that constitutes a building, in order for the drainage of that room to flow promptly, whether or not outside air is promptly introduced into the drainage pipe where the drainage of each floor joins during drainage It is necessary to consider that. That is, if the outside air is not introduced promptly, the drainage is not smoothly performed, so it is necessary to ensure proper ventilation, and thus the above-described drainage pipe is necessary.

  In the apparatus of the present invention, the pipe such as the drainage vertical pipe has a pipe that does not substantially have a joint structure and an inner diameter formed slightly larger than the outer diameter of the pipe. An apparatus main body through which the pipe is passed is installed in a tubular portion having the following. For this reason, if piping is arrange | positioned in the tubular part of an apparatus main body, a clearance gap will be produced between piping outer surface and opening inner surface, Therefore It becomes possible to remove piping, without destroying a slab. In the present invention, a pipe having substantially no joint structure means a pipe that is seamlessly connected from indoor to outdoor, but it is necessary that the pipes are not connected to each other. Instead, it is intended to exclude those connected by tubular portions other than piping as shown in the example of FIG. For example, it is possible to construct a pipe portion length of 10 meters using a pipe obtained by adding a 3 meter pipe.

  The device main body through which the pipe passing through the inside and outside of the housing is passed is placed on the outer surface of the slab. The apparatus main body in the present invention is a part through which the above-mentioned pipe is passed, and since the inside of the apparatus main body does not come into contact with ventilation as in the prior art, it is not regarded as a part of the ventilation pipe. That is, the apparatus main body is installed on the slab and functions as a sheath tube (sheath tube or cannula) that protects the pipe extending from the inside. Therefore, the apparatus main body in the present invention is regarded as a part of the casing. , Not subject to renewal.

  Between the pipe and the apparatus main body, an outer waterproof means for preventing moisture from entering the inside of the apparatus main body from the outside of the casing, and preventing moisture from entering the inside of the casing from the inside of the apparatus main body. Inner waterproofing means. The outer waterproof means is means for waterproofing the outside mainly in the apparatus of the present invention and the inside of the apparatus main body, and rainwater is a main waterproof object. On the other hand, the inner waterproofing means is a countermeasure against leakage into the room because there is a possibility that condensed water may be generated inside the apparatus main body.

  In view of the importance of the above outer waterproofing means in particular, in order to manage the tightening force in the axial direction by the stroke, a gauge for proper management of the tightening force can be used. The gauge comprises, for example, a pair of large and small diameter rings that can be fitted together, and the pair of rings are fitted with a difference in diameter that causes resistance when fitted, and the lengths in the fitting direction are substantially equal, And the color of the outer surface of one ring and the other ring is different, and when a pair of rings are fitted with a predetermined stroke, one ring is hidden by the other ring, and only the color of the other ring becomes, tightening to the appropriate torque What has the structure of making it possible to confirm that it is visually confirmed can be used.

  Both the outer waterproof means and the inner waterproof means are provided between the pipe and the apparatus main body, and thus serve as means for connecting the pipe and the apparatus main body. In addition, although it has already been described that a gap is generated between the outer surface of the pipe and the inner surface of the opening, the gap may be left as it is, or a material such as a heat insulating sheet may be disposed. As a result, the generation of condensed water can be suppressed or reduced.

  It is considered that the present invention is often applied in connection with new construction because of the nature of a waterproof device installed in piping equipment that penetrates a slab of a housing in a building. However, with regard to piping equipment having a configuration in which a gap is formed between the outer surface of the pipe and the inner surface of the opening portion through which the pipe is formed or the gap can be formed, the existing equipment is attached later. It is also possible. In any case, since the present invention does not have a joint structure as in the conventional apparatus, 100% of the effective sectional area of the pipe can be ensured.

  Since the present invention is configured and operates as described above, the structure of the skeleton and the equipment (infill) are separated from each other, so that the construction of the equipment can be renewed without having to break the slab of the skeleton. There is an effect that it is possible to provide a waterproof piping device in a building that can be executed. Further, according to the present invention, in the waterproof device for piping attachment in a building, the facility renewal work can be performed with the minimum necessary work period and work cost.

  Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments. FIG. 1 shows an example 1 of a waterproof piping device in a building according to the present invention. Reference numeral 10 denotes a pipe, 11 denotes a roof slab of an apartment house which is a building, and 12 denotes a device main body. The apparatus main body 12 shown in the figure has a collar portion 13 fixed to the lower surface of the slab 11 on the roof portion of the building at the lower end and an anchor portion 14 disposed inside the slab. The upper end of the slab has a height that reaches a position sufficiently away from the upper surface of the slab, and is a typical example having a slab-driving type pipe 10.

  The apparatus main body 12 is a cylindrical structure having an inner diameter formed slightly larger than the outer diameter of the pipe described later, and a gap g is formed between the outer surface of the pipe and the inner surface of the opening. Moreover, the apparatus main body 12 is casted using ductile cast iron as a material, and has structural portions constituting outer waterproof means and inner waterproof means, which will be described later. That is, on the inner side of the upper end of the apparatus main body 12, a slope 12a that forms an opening that opens upward is provided for the apparatus that constitutes the outer waterproof means 15 described with reference to FIG. On the inner side of the lower part of the apparatus main body 12, a groove portion 12b for arranging a seal ring as the inner waterproofing means 16 is provided. The seal ring as the waterproof means 16 has a support function for holding the pipe 10 together with a function of stopping dew condensation water. For these functions, a slip aid such as soapy water is provided between the pipe outer surface. It is desirable to insert using.

  As shown in FIG. 4, the outer waterproof means 15 includes a ring-shaped flange 17 disposed at an upper portion facing the flange 12 c at the upper end of the apparatus main body 12, and an opening opened downward from the flange 17. A ring-shaped packing 18 disposed between the slope 17a to be formed and the slope 12a opened upward of the apparatus main body 12, and a bolt 19a and a nut 19b for tightening the flange 17 and the flange 12c of the apparatus main body 12 are provided. The packing 18 includes a plurality of rigid spheres 18a disposed between the pipe outer surface and the inclined surfaces 12a and 17a. Therefore, in the configuration of the outer waterproof means 15 of Example 1 described above, the packing 18 is pressed with a strong force as the bolts and nuts are tightened, and the pipe 10 and the apparatus main body 12 are connected by the rigid sphere 18a on the inclined surface 12a. It is possible to firmly bond, preventing moisture from entering the inside of the apparatus main body 20 from the outside of the housing, and exhibiting a support function for holding the pipe 10.

  At that time, in order to manage the tightening force by the bolts and nuts arranged at a plurality of locations in the circumferential direction of the flange by the stroke, a gauge 20 for proper management of the tightening force is incorporated. The gauge 20 includes a pair of small-diameter and large-diameter fitting rings 21 and 22 that can be fitted to each other. The gauges 20 are fitted with a difference in diameter that causes resistance when fitted, and the length in the fitting direction is almost equal. The outer surfaces of the one ring and the other ring 22 are different from each other, and when the pair of rings 21 and 22 are fitted to each other by a predetermined stroke, the one ring 21 is hidden by the other ring 22 and the other ring 22 By using only the color of the ring 22, it is possible to visually confirm that it is tightened to an appropriate torque.

  In Example 1 of the waterproof piping device in a building according to the present invention, the cover 23 covers the outside of the outer waterproof unit 15 in order to protect the outer waterproof unit 15 provided with the gauge 20 for proper management of tightening force. . The cover 23 has a cylindrical structure which is closed at the upper end and opened at the lower end, and is formed with a central through hole 23a through which the pipe is passed so as to cover the pipe 10 from the upper end. It has a slightly open outline. By forming the cover 23 using a transparent resin material or the like, the state of the proper management gauge 20 for tightening force can be visually confirmed. For fixing the cover 23, an external nut 19c that is screwed into the outer end of the bolt nut is used, and an external packing 24 is interposed between the outer waterproof means 15 and the rain water enters. I'm trying to prevent it.

  In the figure, reference numeral 25 denotes a vent metal fitting, which is installed at the upper end of the pipe 10. Reference numeral 26 denotes a waterproof layer laid on the upper surface of the slab. The end of the illustrated waterproof layer 26 covers the base of the pipe 10 rising from the upper surface of the slab 11 and reaches the vicinity of the upper end. The terminal processing 26a is performed by any known method such as binding. Reference numeral 27 denotes a heat insulating material layer, and 28 denotes a presser mortar layer, which has a configuration in which a cushioning material 29 is interposed between the waterproof layer 26 covering the outer surface of the pipe.

  FIG. 2 shows Example 2 of a waterproof piping device in a building according to the present invention, which differs from Example 1 above in terms of the outer waterproofing means 30, and has a slab driving type piping 10 and the like. In other respects, the configuration is common. Therefore, the outer waterproofing means 30 will be described for Example 2, and reference numerals will be used for the other configurations, and detailed description will not be repeated, but it can be said that the present invention is the simplest embodiment.

  In Example 2, the shape and structure of the apparatus main body 12 are the same as those in Example 1, but a single packing 31 is arranged on the slope 12a that forms an opening that opens upward at the upper end thereof. The outer waterproof means 30 is configured. That is, the packing 31 is tightened at the upper end portion 23b of the cover 23 using the tightening force of the nut 19c, thereby preventing rain from entering into the apparatus main body 20 from the outside of the housing. The support function for holding the pipe 10 is achieved (see FIG. 5).

  FIG. 3 shows a third example of the waterproof piping device in a building according to the present invention. Unlike the first and second examples, the outer surface of the pipe and the inner surface of the opening portion 11a of the slab 11 through the pipe 10 are shown. It is configured as an example of attaching to an existing facility that has a gap g therebetween. The apparatus main body 32 in Example 3 is installed by driving the anchor bolt constituting the anchor portion 34 into the slab upper surface while having a flange portion 33 fixed to the upper surface of the slab 11 on the roof top portion of the building. Has been.

  On the inner side of the base portion of the apparatus main body 32, a groove portion 32b for arranging a seal ring as the inner waterproofing means 36 is provided. The seal ring as the inner waterproofing means 36 in Example 3 also has a support function for holding the pipe 10 as well as a function for stopping the dew condensation water. Inserted with aids. The outer waterproofing means in Example 3 is the same as that in Example 2. Therefore, a single packing 31 is arranged on the upper surface of the apparatus body with respect to the slope 12a, and the tightening force of the nut 19c is used at the upper end 23b of the cover 23. Tightened and fixed. Since it is the same as that of Example 1 about another structure, a code | symbol is used and detailed description is not repeated.

  The waterproof piping device in the building of the present invention is configured as described above. In the piping facility that penetrates the slab 11 of the housing, the piping 10 as the interior / facility (infill) and the structural housing (skeleton) are used. Since the slab 11 is separated from the slab 11 (skeleton) that is constructed under the ultra long-term housing guidelines and has durability and earthquake resistance, the piping 10 (infill) that should ensure variability Even if it is necessary to renew, it is possible to complete the necessary work only by replacing the pipe 10 without damaging the slab 11 (skeleton) or the like. Accordingly, the construction period and construction cost can be minimized, and the structure of the housing does not change before and after the construction, and the asset value of the house is increased.
