Description

  The present invention relates to a waterproof construction fixture and a waterproof treatment method used for fixing a waterproof member or a waterproof fixing member disposed in a building frame such as a metal plate, lightweight foamed concrete (ALC), or concrete.

  When waterproofing a roof, a veranda, etc., as shown in FIG. 8 (a), the metal plate, lightweight foamed concrete (ALC), concrete, and the like were bent and cut along the shape of the building housing 6. A waterproof member 33 made of a synthetic resin-coated steel plate is laid, and the waterproof member 33 is fixed by fixtures 31 and 41 made of flat screws or round screws as shown in FIGS. 9 (a) and 9 (b).

  In addition, as shown in FIG. 8B, a plurality of waterproof fixing members 34 made of synthetic resin-coated steel sheets processed into a disk shape or an angle shape may be used. 9 and a synthetic resin covered with the waterproof sheet 5 and the waterproof fixing member 34, covering the waterproof sheet 5 from above and fixing with a fixing tool 31 made of a countersunk screw shown in FIG. 9A, for example. The required parts are joined by solvent welding or heat sealing to perform waterproofing.

  Among these, in particular, when the waterproof member 33 is exposed as in FIG. 8A, it will rain if the fixture 31 is only fixed to the waterproof member 33 provided with the fixture hole. In such a case, there is a risk of water leakage, such as rainwater seeping into the fixture hole.

  Therefore, as shown in FIG. 10, after the waterproof member 33 is fixed by the fixing tool 31, in order to prevent rainwater from penetrating into the gap between the seat surface 31 c of the fixing tool 31 and the peripheral edge 33 e of the waterproof member 33. The sealing material 7 made of, for example, a silicone resin is applied from the upper surface so as to straddle the top surface 31d of the fixture 31 and the surface 33c of the waterproof member 33, and waterproof processing is performed.

  Since the sealant 7 used is usually liquid or semi-solid at the time of application and is cured with the passage of time, it is necessary to provide a curing time after the application until it is completely cured and the adhesion is completed. For this reason, if it rains before it hardens, the sealing material 7 is easily washed away, which may cause problems in terms of work efficiency and waterproof performance.

  Therefore, an elastic member made of a sealing material or elastic resin is applied or pasted in advance between the seat surface of the fixture and the upper surface of the waterproof member, and sealed without gaps by the fastening force of the fixture. Improved fixtures have been proposed.

For example, a fixing device (Patent Document 1) in which a sealing material is applied to the screw portion of the fixing device, a fixing device (Patent Document 2) in which a ring-shaped elastic resin body is interposed on the seat surface, and a sealing material is applied to the seat surface. In addition, a fixing device (Patent Document 3) in which a screw portion is coated with a resin is disclosed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view showing a waterproof construction fixture comprising a countersunk screw of the present invention.

  The waterproof construction fixture 1 according to the present invention shown in FIG. 1 has a base made of metal, is composed of a head portion 1a and a screw portion 1b, and a top driver 1d on the top surface 1d at the upper end of the head portion 1a. Is provided with a cross hole 1e. As for the holes that can be engaged here, holes of various shapes such as a minus hole, a square hole, and a star hole that can correspond to each type of driver can be selected.

  A seat surface 1c is formed in a conical shape on the back surface side of the head 1a, and the thermoplastic resin 2 is coated on the seat surface 1c.

  The type of the thermoplastic resin is not particularly limited as long as it is a thermoplastic resin, but is preferably one that can be heat-sealed to the type of synthetic resin on the surface of the waterproof member or the waterproof fixing member. Furthermore, it is preferable that it is resin which can be solvent-welded.

  Examples of the thermoplastic resin include vinyl chloride resins, chlorinated polyethylene resins, chlorinated vinyl chloride resins, olefin resins such as polyethylene and polypropylene, ethylene-propylene elastomers, ethylene-vinyl acetate resin copolymers (EVA). Resin) and other vinyl acetate resins, acrylic resins such as acrylates, polyester-based, acrylic-based, and epoxy-based hot mate-based adhesives.

  2 to 4 show sectional views of the waterproof member 3 or the waterproof construction member 4 fixed by the waterproof construction fixture 1.

  The waterproof member 3 as used herein refers to a waterproof member laid mainly on the outside of a building that is exposed to wind and rain, such as a veranda or a flat roof. On the other hand, the waterproof fixing member 4 is a waterproof sheet on a building frame or the like. It is a member for joining waterproof sheets used in an insulating waterproof construction structure in a so-called sheet waterproof construction in which the required locations are joined.

  At least the surface of the waterproof member and the waterproof fixing member needs to be made of a synthetic resin. As shown in FIGS. 2 to 4, these waterproof members or waterproof fixing members are waterproof members 3 or waterproof fixings made of resin-coated steel plates having steel plates 3b and 4b as base materials and covered with synthetic resins 3a and 4a on their surfaces. The member 4 can be cited as a representative one, but is not limited to this. The front and back of the punching plate provided with a number of holes made of metal, or one of which is coated with a synthetic resin, or a resin made of polyester, etc. A synthetic resin material having a net made in the middle or a synthetic resin single material not including a base material may be employed.

  Further, the shape is selected from a flat plate shape, a shape processed according to the shape of the base, a disk shape, a band shape, an angled shape subjected to bending processing, and the like, and there is no limit to the range. For example, a waterproof fixing member made only of an olefin resin obtained by injection molding a polypropylene resin into a disk shape, or a waterproof member processed into an angle shape obtained by bending a hard vinyl chloride resin plate It is done. Moreover, about the surface which a synthetic resin coat | covers, what was made | formed not only on one side but on both surfaces may be sufficient.

  As the synthetic resin 3a, 4a forming the surface of the waterproof member 3 or the waterproof fixing member 4, the above-described thermoplastic resins such as vinyl chloride resin and olefin resin are used, natural rubber, styrene rubber, butylene rubber, butadiene rubber. , Rubber compositions such as isobrene rubber, acrylic rubber and nitrile rubber, asphalt compositions, and curable resin compositions such as silicone and epoxy compounds.

  These synthetic resins 3a and 4a are joined to the thermoplastic resin 2 in the fixture 1 by solvent welding or thermal fusion. As the thermoplastic resin 2, when the synthetic resins 3a and 4a are vinyl chloride resins, Vinyl chloride resin, EVA resin, and acrylic resin are preferably selected. When the synthetic resins 3a and 4a are olefin resins such as polyethylene and polypropylene, olefin resins such as polyethylene and polypropylene, ethylene -It is preferable to select a hot mate adhesive such as a propylene elastomer, polyester, acrylic or epoxy. In addition, it is more preferable that the seating surface 1c of the waterproof construction fixture 1 is previously subjected to a primer treatment or the like for increasing the adhesiveness before the thermoplastic resin 2 is coated.

  The coating thickness of the thermoplastic resin 2 is preferably 0.1 mm to 2.0 mm. If the thickness is less than 0.1 mm, the waterproof member or waterproof fixing member to be joined may not be sufficiently joined. If the thickness exceeds 2.0 mm, the waterproof construction fixture 1 is sufficiently tightened. This is because it may cause problems in workability such as being unable to do so.

  The method for coating the seating surface 1c of the waterproof construction fixture 1 with the thermoplastic resin 2 is to apply the thermoplastic resin 2 as a solution with a sol, emulsion, or solvent, or as a molten state by heating to the seating surface 1c. Heating to a temperature that is equal to or higher than the melting point of the thermoplastic resin 2 that covers the head 1a of the waterproof construction fixture 1, and flows to the seat surface 1c of the head 1a of the waterproof construction fixture For example, there is a method that is performed by a fluidized dipping method in which the powdered thermoplastic resin 2 is adhered by an air current and melted and coated.

  In the present invention, the thermoplastic resin 2 needs to be coated so as to include at least the seating surface 1c, but may be coated over the entire surface of the waterproof construction fixture 1, or other than the screw portion 1b. The thermoplastic resin 2 may be coated on all surfaces. Especially, as shown in FIG. 5, it is preferable that the thermoplastic resin 12 is coated in a cap shape on at least the surface including the seat surface 11c and the top surface 11d of the waterproof construction fixture 11. This is because the head 11a is directed downward and the head 11a is immersed in a solution such as a sol of the thermoplastic resin 12 with the screw 11b in the waterproof construction fixture 11 being gripped. This is because the fixture 11 can be manufactured. Moreover, it may become difficult to exfoliate resin by covering with a cap shape. The thermoplastic resin 12 used at this time is preferably a vinyl chloride resin because it is easy to mold with a sol.

  Next, the waterproofing method according to the present invention will be described.

  First, the waterproofing method performed with respect to a waterproof member is demonstrated with reference to FIG.

  FIG. 2 shows a state in which the waterproof member 3 is arranged at a required location of a building housing 6 such as concrete. The place where the waterproofing member 3 is disposed includes a place where an external floor such as a veranda or a flat roof where wind and rain blow in is mainly formed.

  This waterproof member 3 has a steel plate 3b as a base material, the surface thereof is covered with a synthetic resin 3a, and a fixing hole for allowing the threaded portion 1b of the waterproof construction fixing tool 1 to be inserted is provided at a predetermined portion thereof. . A peripheral edge 3e that protrudes downward is formed around the fixture hole, and an accommodating portion 3f that is large enough to accommodate the head 1a of the waterproof construction fixture 1 is provided.

  Therefore, first, the waterproof construction fixture 1 according to the present invention is inserted into the fixture hole of the waterproof material 3 through the threaded portion 1b, and the thermoplastic coated on the seating surface 1c of the waterproof construction fixture 1. Screwing is performed until the resin 2 and the synthetic resin 3a coated on the peripheral edge 3e of the waterproof member 3 are in contact with each other. At this time, the head 1a of the waterproof construction fixture 1 is housed in the housing portion 3f of the waterproof member 3, and the top surface 1d of the waterproof construction fixture 1 and the surface 3c of the waterproof member 3 are substantially horizontal.

  And the required part of the synthetic resin 3a coat | covered with this waterproof member 3 and the thermoplastic resin 2 coat | covered with the fixing tool 1 for waterproof construction is joined by solvent welding or heat sealing | fusion. By carrying out like this, while waterproofing with respect to a fixture hole can be performed, the required part of the synthetic resin 3a and the thermoplastic resin 2 will be in the state latched, and the screw | thread loosening of the fixture 1 for waterproof construction can be prevented.

  Here, in the case of bonding by solvent welding, a solvent that can melt the thermoplastic resin 2 and the synthetic resin 3a with each other is used as the solvent. For example, tetrahydrofuran (THF), ethyl acetate, cyclohexane, methyl ethyl ketone, methyl alcohol, ethyl alcohol, isopropyl alcohol and the like are preferably used. In particular, when the thermoplastic resin 2 and the synthetic resin 3a are polyvinyl chloride resins, tetrahydrofuran (THF) is particularly preferable from the viewpoint of adhesiveness.

  As an example of the waterproof treatment method by solvent welding, an appropriate amount of solvent is applied to the boundary portion between the synthetic resin 3a coated on the waterproof member 3 and the thermoplastic resin 2 coated on the waterproof construction fixture 1 by a syringe or a brush. The method of dripping is mention | raise | lifted. In this case, the waterproof construction fixture 1 suitable for solvent welding preferably has a conical surface 1c. This is because when the solvent is dropped or applied, the solvent enters the gap in the fixture hole along the peripheral edge 3e of the waterproof member 3 from above, thereby increasing the joining workability.

  As another waterproof treatment method by solvent welding as described above, a screw for the waterproof construction fixture 1 is loosened in advance, and a gap is provided between the peripheral edge 3e of the waterproof member 3 and the thermoplastic resin 2, and the gap There is a method in which a solvent is dropped or a brush dipped in a solvent is inserted and applied, and then a loosened screw is tightened again. This method has an advantage that the entire surface of the seat can be joined.

  Next, the case of waterproofing by heat fusion will be described. As for waterproofing treatment by heat fusion, there are a method using a hot air gun and a method using an induction heater.

  The method using the hot air gun is performed by heating the thermoplastic resin 2 to a melting temperature or higher by heating means such as a hot air gun at a required portion of the thermoplastic resin 2 and the synthetic resin 3a. In this method, since the hot air gun is portable, work efficiency is good.

  As for the method using the induction heater, at least one of the head 1a in the waterproof construction fixture 1 and the steel plate 3b coated with the waterproof member 3 is one of the induction heater and at least thermoplastic due to the eddy current. The heating is performed so that the resin 2 reaches the melting temperature or higher. This method is preferable in that the temperature of the seating surface can be made more uniform, and the bonding strength between the thermoplastic resin 2 and the synthetic resin 3a can be obtained stably. In addition, the method using heat fusion including the method using the hot air gun and the method using the induction heater is preferable in terms of securing a working environment because no solvent is used.

  After bonding by the waterproof member 3 by the above-described solvent welding or heat sealing, the top surface 1d of the waterproof construction fixture 1 is waterproofed as shown in FIG. 3 in order to perform a more reliable waterproofing process. A sealing material 7 made of, for example, a silicone resin is preferably applied so as to cover the upper surface of the member 3 with the surface 3c. In this way, a more reliable waterproofing process is possible.

  Next, a waterproofing method according to the present invention applied to the waterproof fixing member will be described with reference to FIG.

In this waterproof fixing member 4, a peripheral edge 4 e protruding downward is formed around the fixture hole, and an accommodating portion 4 f large enough to accommodate the head 1 a of the waterproof construction fixture 1 is provided. It is a thing.

  First, the waterproof fixing member 4 is a thermoplastic resin coated on the seating surface 1c of the fixing tool 1 by the screw part 1b of the waterproofing fixing tool 1 being screwed into the fixing tool hole by the fixing tool 1 for waterproofing. 2 is fixed in a manner in contact with the synthetic resin 4 a covered with the waterproof fixing member 4. At this time, the head 1a of the waterproof construction fixture 1 is housed in the housing portion 4f of the waterproof construction member 4, and the top surface 1d of the waterproof construction fixture 1 and the surface 4c of the waterproof construction member 4 are substantially horizontal. It is in the state.

  The required portions of the synthetic resin 4a covered by the waterproof fixing member 4 and the thermoplastic resin 2 covered by the waterproof construction fixture 1 are joined by the above-described joining method by solvent welding or thermal fusion. Waterproofing is done.

  Next, from above, a waterproof sheet 5 made of a synthetic resin is laid, and the waterproof sheet 5 and the synthetic resin 4a covered with the waterproof fixing member 4 are formed by solvent welding or heat fusion according to a conventional method. The waterproof sheet 5 is fixed by being joined at a required portion.

  According to the heat insulating waterproof structure made in this way, for example, the heat insulating material 8 causes material deterioration over a long period of time, and the waterproof fixing member 4 disposed thereon receives the weight of the waterproof sheet 5 and the like, and the heat insulating material 8, the thermoplastic resin 2 in the waterproof construction fixture 1 and the synthetic resin 4 a in the waterproof fixing member 4 are joined, so that the sinking is prevented, and therefore the waterproof fixing member 4. There is an effect of preventing an accident that leads to water leakage, such as rainwater entering the gap without causing a gap between the waterproof construction fixture 1 and the waterproof construction fixture 1.

And the thermoplastic resin 12 which consists of a vinyl chloride resin is coat | covered with the cap shape over the seat surface 11c and the top surface 11d. The coating of the thermoplastic resin 12 is formed by dipping the head 11a of the waterproof construction fixture 11 downward in a vinyl chloride resin-based sol and then cooling.

  As shown in FIG. 6, the waterproof construction fixture 11 has a threaded portion 11b inserted into a flat fixture hole provided in a required portion of a waterproof member 13 made of a hard vinyl chloride plate, and is inserted into a seat surface 11c. The waterproof member 13 is fixed in such a manner that a required portion of the surface 13c is brought into contact with the coated thermoplastic resin 12. And the required part of the thermoplastic resin 12 in the seating surface 11c to contact | abut and the waterproof member 13 in the surface 13c is joined by solvent welding, and the waterproof process is made | formed.

  In the joining by the solvent welding, the thermoplastic resin 12 coated on the seating surface 11c of the waterproof construction fixture 11 is set in a state where the screws are loosened in advance before the waterproof construction fixture 11 is secured by tightening the screws. This is done by inserting a brush dipped in tetrahydrofuran (THF) into the gap formed between the surface 13c of the waterproof material 13 and tightening the loosened screw immediately after applying a proper amount.

  Next, an example of a method using induction heating in the waterproofing method using heat fusion according to the present invention will be described with reference to FIG.

  The waterproof fixing member 14 shown in FIG. 7 has a disk shape with an outer diameter of about φ60 mm, and is obtained by injection molding a polypropylene resin. A fixture hole is provided in the central portion, and a peripheral edge 14e around the fixture hole and an outermost edge are formed in a hook shape projecting obliquely downward. Since the edge 14e around the fixture hole protrudes obliquely downward, the head portion 21a of the waterproof construction fixture 21 is accommodated, and the head portion 21a does not protrude upward when fixed.
