Description

  The present invention relates to a method and member for repairing a drain trap installed in a bathroom or the like in an apartment house such as a condominium, an office building, or a general residential house.

  Conventionally, a plurality of techniques (inventions) are known as a method of repairing or refurbishing this type of drainage and lap. As a first known example, after removing and removing the rust of the defective portion such as rusting, fouling defect, fusing, etc. inside the main body of drainage and wrap, an underwater curable adhesive or adhesive putty etc. is applied to the defective portion This is a drainage trap sealing part restoration method in which the adhesive wall is coated and buried to refill the recesses such as rusting and melting on the inner wall, and to restore the trap top to the initial height (Patent Document) 1).

  According to this restoration method, the restoration work for the floor drain trap with the waterproof layer does not damage the floor waterproof layer, and the initial performance and function related to the sealing and sealing of the drain trap body are completely restored. Can do. There is no destruction work such as cutting the trap body, and there are few materials and tools used for the trap repair method, so it does not occupy space for construction, and it does not become a large-scale construction, and it is inexpensive as a whole. It can be repaired.

  A second known example is a drainage trap repairing member having a cylindrical rising portion protruding inside the trap body, and the repairing member is made of a soft synthetic resin that covers the inner peripheral surface of the trap body. The formed cover main body and the rising cover portion formed of a hard synthetic resin that covers the inner peripheral surface and the outer peripheral surface protruding into the trap main body of the rising portion are integrally formed, and caulking agent is used to the drain trap. It is a repair member constituted so that it may adhere (refer to patent documents 2).

  And a drainage trap can be easily repaired only by adhere | attaching the repair member which integrally provided the cover main body and the rising cover part to the drainage trap via a caulking agent. In addition, since the drainage member is bonded to the drainage trap by the caulking agent, even if the drainage trap is larger than the repair member and a gap is generated, the gap can be easily created by adjusting the coating amount of the caulking agent. be able to. Furthermore, since the rising cover portion is formed of a hard synthetic resin, there is no risk of buckling or deformation even when the rising portion of the drain trap is shorter than the rising cover portion of the repair member.

  Furthermore, the third known example is a drain trap repairing method, in which the drain trap eye plate and slag are removed, the drain trap is cleaned and cleaned, and then the middle cylinder is removed. A synthetic resin cover formed by coating the inside of the drain trap including paint with a size and shape suitable for being attached to the outside or the inside of the middle cylinder based on the mold of the middle cylinder manufactured in advance. This is a repair method in which the cover is attached to the inner cylinder (see Patent Document 3).

According to this repair method, not only is the defective part reinforced with putty or a synthetic resin partial repair agent, but the entire inner cylinder is covered with a cover that is closely adhered to the inner cylinder, and the entire shape is almost the original shape. Therefore, the function of the drain trap can be restored.
In particular, even when the upper part of the middle cylinder is greatly damaged and a predetermined height is lost, it can be dealt with, so that it can be widely applied in repair work of drain traps that are difficult to replace. That's it.

  By the way, in this type of drainage trap, the sealing part is composed of a rising cylinder connected to the drainage pipe and a cap-like member that covers the upper part with a predetermined interval. It is the rising cylinder that is most damaged by use. For this reason, in the conventional repair or repair work, there has been a proposal that mainly repairs the entire sealed portion or the rising cylinder.

  However, in the first known example, an adhesive such as an underwater curable adhesive or an adhesive putty is applied and embedded in the defect portion to refill the defect concave portion, and at the same time, the trap upright is set at the initial height. In the embodiment, specifically, the adhesive is formed with fingers or by manual work such as “spa”, but as an actual problem, there is a certain amount of adhesive for bonding to metal. Fluidity is necessary, and even if it is overcoated and thickened to form, it takes some time, and even when using an adhesive putty, it retains its shape but has low adhesion to metal. However, there is a problem that it takes time to solidify and lacks feasibility.

  In the second known example, the cover body formed of a soft synthetic resin that covers the inner peripheral surface of the trap body, and the hard synthetic resin that covers the inner peripheral surface and the outer peripheral surface of the rising portion of the cylindrical body are formed. The repair member, which is integrally formed with the rising cover part, is bonded to the drain trap with a caulking agent. Even though the workability is good, the drain trap to be repaired has a depth of the trap body. Not only the diameter and height of the rising part of the cylinder, but also various sizes, the repair member must be prepared for each size, and it is integrated with soft and hard synthetic resin. Since it is formed, once it is manufactured as a repair member, it cannot be used unless there is a drain trap repair request that matches it. In short, a variety of repair members are prepared and stored with knowledge of waste. There is a problem that must be managed.

  Further, in the third known example, a size and shape of a wooden mold that is the same as the middle cylinder of the drain trap to be repaired in advance and is attached to the outside or the inside of the middle cylinder based on the wooden mold. This is a repair method in which a cover made of synthetic resin is molded and this cover is attached to the inner cylinder of the drain trap and bonded, but it is a very difficult task to make a wooden mold in advance. In addition, in the description of the embodiment, “the 50A drainage vinyl chloride tube 40 is heated to the wooden mold, and as shown in FIG. 4, this is pushed into the wooden mold 20 and its outer peripheral surface is a tapered tree. The cover 30 is manufactured by forming it into a cylindrical tube that matches the mold 20, ”and it is difficult to understand the intention of forming the outer peripheral surface of the vinyl chloride tube in a tapered shape by taking extra effort. Put the missing part of the inner cylinder into putty or synthetic resin It is required to be reinforced with a partial repair agent and to be covered with a cover that is tightly bonded to the inner cylinder. doing.

  Therefore, in any of the above-mentioned known technologies, the uncertain and troublesome work of forming or repairing the corroded rising portion or middle cylinder, which is a cause of the loss of the function of the drain trap, to the original state using the mold at the repair site. There is a problem to be solved in solving the problem and in solving the poor workability due to the long work time.

The present invention provides, as specific means for solving the above-mentioned problem, the first invention is that at least a rising part rising from the center bottom part of the main body part, a sealing cap positioned above the rising part, and a lower part of the rising part A drainage trap repairing method comprising a drainage pipe connected to a drainage pipe, wherein the rising portion is cut off, a polishing / polishing step for removing dirt adhering to the inside of the drainage trap, and the inside of the drainage trap. A cleaning / drying process for cleaning and drying, a rust-proofing process for rust-proofing the inside of the drain trap, and a repairing member formed of a plastic cylinder after the rust-proofing process are attached to form a recycled rising part And a process for repairing the drainage trap.
Further, as a second aspect of the invention, at least a plastic cylindrical body is formed to have a length that forms an insertion portion and a regeneration rising portion reaching into the drainage pipe , and a boundary position between the insertion portion and the reproduction rising portion. Further, the present invention provides a drainage trap repairing member characterized by integrally forming a secondary body part having a shape along the inside of the stopper member or the body part of the drainage trap.

In the first invention according to the present invention, the attachment of the repair section, it is inserted to a position reaching into the drain pipe; and the rust-proofing step is carried out by coating with a coating or putty resin paint Is included as an additional requirement.

According to the first aspect of the present invention, by removing the corroded rising portion, which is the cause of the loss of the function of the drain trap, by attaching a repair member having a regenerative rising portion formed of a plastic cylinder, It is possible to easily regenerate the drainage trap function, and it is possible to easily perform the construction for the regeneration and to use it for a long time after the regeneration.
In addition, the repair member according to the second invention can be easily formed with a plastic cylinder, and it is inexpensive and can be inserted until the insertion portion reaches the drainage pipe. There is an excellent effect of being able to.

It is explanatory drawing which shows the repair method of the waste_water | drain trap which concerns on preferable embodiment of this invention in order of the process of (A)-(D). It is the perspective view which showed the (A) 1st repair member and (B) 2nd repair member which are used for the repair method which concerns on the embodiment. It is explanatory drawing which showed schematically the situation (A) (B) repaired using the 2nd repair member which concerns on the embodiment. It is sectional drawing which each showed schematically the drain trap after repairing with (A) 1st repair member and (B) 2nd repair member by embodiment of this invention.

The present invention will be described based on the illustrated embodiment. 1-4, the preferable method of repairing the drain trap will be described.
For example, a drain trap 1 installed in a bathroom or the like in a house is generally composed of a main body portion 2, a rising portion 3 rising from the center bottom, a drain pipe 4 connected to a drain pipe, and a sealing cap 5. For the sealing cap 5, those conventionally used can be used as they are.

  The repair of this type of drain trap 1 is to prevent the rising portion 3 from corroding and losing the sealing function in relation to the sealing cap and leaking unpleasant odor from the drain pipe. This is mainly to repair the corroded portion of the rising portion 3 as it was.

  Therefore, as shown in FIG. 1 (A), the present invention is retreated by the occurrence of the corroded portion 3a from the original height position indicated by the imaginary line at the rising portion 3, and the sealing function is lost. In repairing the drain trap 1 in which dirt 8 such as rust and scale adheres to the inside of the main body 2 and the drain pipe 4, first, the electric cutter 11 equipped with the diamond blade 10 is attached to the rising portion 3. The rising part cutting process which cuts and removes from a root side using is performed. In this case, the base side of the rising portion 3 is left as a remaining portion 3b and is cut off (about 5 ± 2 mm). Diamond blades are diamond powders electrodeposited with aluminum on the peripheral edge of a disk-shaped metal plate, and are the same type of cutter used when cutting asphalt or cement for road works. is there.

  After the rising portion cutting step, as shown in FIG. 1 (B), for example, using a mechanical polishing machine, an electric wire brush 12 or the like, adhere to the inside of the main body portion 2 or the inside of the drain pipe 4. A so-called scouring / polishing process for removing the dirt 8 is performed. Note that the rising portion cutting step and the polishing / polishing step may be performed in reverse.

  After the rising portion cutting step and the scouring / polishing step, as shown in FIG. 1 (C), the inside of the drain trap 1, that is, the inside of the main body portion 2 and the drain pipe 4 is washed with water, and chips and foreign matters are removed. After performing a cleaning and drying process of cleanly cleaning and drying so as not to occur, a resin coating 13 is applied to the entire surface of the main body 2 and the drain pipe 4 to perform a rust prevention process. The resin coating 13 used in this case is a two-component resin with a relatively short pot life. In addition, when the operation | work which apply | coats the resin coating 13 inside the drain pipe 4 is difficult, application | coating may be abbreviate | omitted.

  After the rust prevention treatment step, as shown in FIG. 1 (D), the first repair member 14 shown in FIG. 2 (A) and the second repair member 14 shown in FIG. On the other hand, for example, the first repair member 14 is disposed and attached integrally. In attaching the first repair member 14, the same kind of resin paint as described above is applied to the lower end portion of the repair member 14 and then attached to the drainage pipe 4 for the purpose of rust prevention treatment. After the resin paint 13 is applied, the repair member 14 is attached while the softness (crosslinking reactivity) still remains in the paint, thereby thinly applying the resin paint 13 and the repair member 14 previously applied. The paint and the paint are cross-linked to bond together and can be attached stably. Further, when the resin paint is not applied to the drain pipe 4, the resin paint is applied thickly on the lower end side of the repair member 14 and is inserted into the drain pipe 4 to fill the gap with the drain pipe 4. Can be integrated and rust-proof.

  The repair member 14 shown in FIG. 2 (A) is a first repair member, which basically forms a new rising portion in place of the cut rising portion 3. A commercially available plastic pipe (cylinder) is used by cutting it to a required length, and the outer diameter of the cylinder is selected to be slightly smaller than the inner diameter of the drainage pipe 4, so that the drainage pipe 4 is stable. It has a length (insertion portion) 16 that can be inserted in a state and a length 17 (reproduction rising portion) that protrudes into the main body 2, and is positioned at a position that protrudes as the reproduction rising portion 17. This ring-shaped stopper member 15 has a simple structure integrally formed. Moreover, what was shown to FIG. 2 (B) is a 2nd repair member, and the secondary main-body part made from resin of the shape which follows the inner side shape of the main-body part 2 of a drain trap at the position of a stopper member, or respond | corresponds substantially. The secondary main body portion 18 is formed to have a diameter slightly smaller than the inner dimension of the main body portion 2, and the other constituent portions, that is, the insertion portion 16 and the like. In the point which has the structure with the reproduction | regeneration rising part 17, it is the same as a 1st repair member.

  As shown in FIG. 1D, in the first repair member, the stopper member 15 comes into contact with the remaining portion 3b by inserting and attaching the lower end portion of the repair member 14 to the drain pipe 4. The gap between the two is completely filled with the resin coating applied in advance, and since the seat is positioned and stable, the planned length projects into the main body 2, and the regeneration rising portion 17 as the drain trap 1 is formed. The resin coating 13 and the repair member 14 that are integrally formed and are applied to the lower end portion of the drainage pipe 4 are integrally coupled, and there is no fear of water leakage.

  Further, the second repair member is used when it is recognized that not only the rising portion 3 of the drain trap 1 but also the main body portion 2 is considerably painful, as shown in FIGS. 3 (A) and 3 (B). As described above, after the rust prevention treatment step, the putty 7 is applied to the inner upper portion of the main body 2 in a ring shape having a considerable thickness, and the insertion portion 16 on the lower end side of the repair member 14 is inserted into the drainage pipe 4. By aligning and forcibly pushing the secondary main body 18 into the main body 2, the putty 7 is sequentially extended to fill the gap between the secondary main body 18 and the main body 2 and to be in a stable state. Can be attached. Further, when the second repair member 14 is used, for example, the putty 7 is applied to the entire inner surface of the main body 2 with a required thickness without performing the rust prevention treatment, and the secondary main body 18 is forcibly applied. By pushing into the gap, the gap between the main body 2 and the secondary main body 18 is completely filled with the putty 7 and the air layer disappears, so that a rust prevention effect occurs. Hit.

  After the repair member 14 is attached in this manner, as shown in FIGS. 4A and 4B, the sealing cap 5 is dropped from the opening side of the main body 2 so as to be placed above the regeneration rising portion 17. After covering, the function as the drain trap 1 is restored by disposing the eye plate 6 in the opening of the main body 2. In addition, the code | symbol 19 in the figure is a floor surface used as a bathroom washroom.

  In preparing the repair member 14, for example, in the case of apartment houses such as condominiums, the design book created at the time of application for construction permission is kept at the management company of the building. The blueprints show the drain traps and pipes used for the building, so you can see the status of the drain traps you are going to repair in advance, and the actual names installed at the site, such as manufacturer name, product number, size, etc. The size of the secondary main body 18, the selection and cutting length of the plastic pipe (cylinder), and the mounting position of the secondary main body 18 and the stopper member 15 are also accurately set in advance in the planned position. It can be installed and prepared. Moreover, about the individual house, the drainage trap to be repaired can be confirmed in advance, the size can be measured, and the repair member 14 can be created in advance.

  The drain trap repairing method according to the present invention uses a repair member formed of a plastic cylinder in particular, so that the state of the main body and the rising portion in the drain trap to be repaired in advance, that is, the position and size. Therefore, it is possible to prepare in advance according to that, and it is possible to easily repair by bringing in a repair member that has been created in advance without any extra creation work at the construction site. Even if the shape of the sheath is different, it can be easily created according to it and can be widely applied to the repair of drain traps.
