Description

  The present invention is a waterproof repair method applied to a waterproof structure in which a waterproof sheet is laid with a heat insulating material interposed on the rooftop of a building, etc., when an attempt is made to install a new waterproof sheet as the existing waterproof sheet deteriorates. In detail, it can prevent problems such as a decrease in fixing strength and damage to waterproof sheets and fixing plates due to sag (permanent strain) of the heat insulating material, and can easily repair existing waterproofing layers in a short period of time. The present invention relates to a repair method and a repair structure that can reduce the generation of waste by repair.

As a method of waterproofing concrete foundations, such as on the roof of a building, waterproofing is ensured by attaching the entire surface of a waterproof sheet made of an elastomer material such as rubber, polyurethane, or other resin to the surface of the foundation with an adhesive. There is a close contact method. There is also a heat insulating waterproofing method in which a heat insulating layer made of a foamed sheet or the like is interposed between a base and a waterproof sheet in order to impart not only waterproof performance but also heat insulating properties .

  A waterproof structure in which the entire surface of the waterproof sheet is attached to the base with an adhesive, and the waterproof sheet is made of a material having excellent physical properties such as weather resistance, and the waterproof performance is maintained over a long period of time. However, it is inevitable that the waterproof sheet will deteriorate due to being exposed to wind and rain for many years and being exposed to the ultraviolet rays of the sun, and eventually it will be necessary to repair it. .

  When repairing such a waterproof structure, the existing waterproof sheet attached to the base is not only deteriorated, but also the adhesive strength between the existing waterproof sheet and the base is reduced. Since there is a possibility, peel off the entire surface of the existing waterproof sheet from the base, clean the surface of the base, etc., and then apply an adhesive to the entire surface of the base to apply a new waterproof sheet to the entire surface of the base. The method of re-pasting is common.

  However, when peeling off the existing waterproof sheet over the entire surface in this way, it takes a lot of labor and time to remove the waterproof sheet in a structure where the waterproof area is very large, and the repair work takes several days. It will be over. Thus, if the renovation work takes a long time, there is a possibility that there will be rain during that period, and there is a possibility that rain leakage may occur if the groundwork is not waterproof. The peeled existing waterproof sheet must be disposed of as industrial waste. However, if the existing waterproof sheet is peeled over the entire surface, the amount of disposal increases, resulting in problems from the environmental viewpoint.

The existing tarpaulin is not removed or partially removed, and a new tarpaulin is laid on the existing tarpaulin so that the work of removing the existing tarpaulin can be omitted and the generation of waste can be reduced. it can. For example, Patent Document 1 discloses that an existing waterproof sheet is partially removed and then a new waterproof sheet is laid thereon. The new waterproof sheet is fixed to the base using a new fixing tool.

Further, in Patent Document 2 , as a method of repairing a waterproof structure in which a sheet is closely fixed to an underlayer with an adhesive, the existing waterproof sheet is partially peeled off, and the exposed underlayer and the remaining existing waterproof sheet are adhered using an adhesive. A method of fixing is disclosed.

Japanese Patent Laid-Open No. 10-61207 JP 2002-364125 A

  According to the method of Patent Document 1, the effort to remove the existing waterproof sheet is certainly reduced, the amount of waste can be reduced, and the influence from the existing waterproof sheet can be blocked by the insulating sheet. However, since the existing waterproof sheet is partially removed, it cannot be said that there is no hassle. Moreover, when the existing waterproof sheet is an adhesion method in which the entire surface is attached to the base with an adhesive, it is difficult to remove the existing waterproof sheet.

  Further, the method of Patent Document 2 can be repaired even in the case of a waterproof sheet laid and bonded by a close-contact method, but there is still a problem that the removal work of the existing waterproof sheet is troublesome. However, the strength of the existing waterproof sheet has decreased during long-term use, and even if it is difficult, it is necessary to partially peel off the existing waterproof sheet to secure a portion where the new waterproof sheet is directly bonded to the ground. In order to solve these problems, the new waterproof sheet is fixed to the base by a mechanical fixing method instead of adhesion.

  However, in the case of heat insulation waterproofing with a heat insulation layer interposed, when a new waterproof sheet is laid using the existing heat insulation layer as it is, the new waterproof sheet can be directly fixed to the ground by mechanically fixing, If the fixed plate is disposed on the heat insulating layer, the heat insulating layer may be sunk later by walking or the like.

  FIG. 1 is a side view of an essential part where the sheet waterproofing repair method of the present invention is applied. The renovation of waterproof structure in the present invention means that a waterproof sheet made of an elastomer material such as rubber or resin is laid on the foundation of a building such as a building or a parking lot. It is said that laying down and redoing waterproofing work.

Since the existing waterproof sheet 2 is one which is used for many years, with a waterproof sheet itself has deteriorated, the fixing force to the underlying tarpaulin also possible situation not sufficient, a new waterproof sheet 1 thereon Even if laid and fixed, it will peel off together with the existing waterproof sheet 2. Therefore, it is necessary to fix the newly installed waterproof sheet 1 directly to the ground.

In the present invention, the thermal insulation waterproofing is performed by interposing the thermal insulation layer 3 between the base and the existing waterproof sheet 2, and the thermal insulation layer 3 is disposed under the existing waterproof sheet 2. When the fixing plate 4 is arranged from above the heat insulating layer 3 to fix the new waterproof sheet 1 and is fixed by driving with the anchor member 5, the heat insulating layer 3 made of foam or the like gradually hangs (permanent strain). As a result, the thickness is reduced, which causes wobble in the fixing plate 4 that should have been anchored.

Therefore, in the present invention, in the place where the fixing plate 4 for fixing the newly installed waterproof sheet 1 is arranged, the area is about 50 to 500 cm ² and the thickness is 0.5 to ² on the existing heat insulating layer 3 such as a circle or a rectangle. An adjustment plate 6 of about 0.0 mm is installed, a fixing plate 4 is disposed thereon, and the adjustment plate 6 and the fixing plate 4 are driven and fixed to the base S by an anchor member 5. By adopting such a structure, the surface pressure applied to the existing waterproof sheet 2 is dispersed by the area of the adjustment plate 6 by driving the fixing plate 4 with the anchor member 5, and is under the existing waterproof sheet 2. The existing heat insulation layer 3 is compressed and becomes sag (permanent strain), and the fixing force of the fixing plate 4 is loosened, or the head of the anchor member 5 protrudes from the fixing plate 4 and damages the new waterproof sheet 1 It is possible to eliminate problems such as

If the area of the adjusting plate 6 is less than 50 cm ² , the dispersion of the surface pressure is insufficient and the amount of compression of the heat insulating layer 3 increases, and if it exceeds 500 cm ² , the area is too wide and the workability deteriorates. Further, if the thickness is less than 0.5 mm, it is easily deformed due to insufficient rigidity and the effect of dispersing sufficient surface pressure cannot be obtained, and if it exceeds 2.0 mm, the step on the surface of the newly installed waterproof sheet 1 becomes large. It is not preferable in appearance.

FIG. 2 shows another example of the present invention. In the example of FIG. 2, the existing heat insulating layer 3 is partially removed at a place where the fixing plate 4 for fixing the new waterproof sheet 1 is arranged. In the removed recess, an adjustment plate 6 is installed to adjust the height to the same level as that of the heat insulation layer 3. Yes. By adopting such a configuration, in place of the existing heat insulating layer 3 in which the sag (permanent distortion) has occurred, the adjustment plate 6 is placed on the base in the portion compressed by the anchor member via the fixed plate 4. If a material that is difficult to sag is used for the adjustment plate 6, the fixing force by the anchor member is loosened, the fixing plate 4 or the anchor member 5 breaks, the anchor member 5 protrudes on the fixing plate 4, or a newly installed waterproofing Problems that may lead to damage of the sheet 1 can be prevented.

  The adjustment plate 6 used in the example of FIG. 2 is preferably made of a material having excellent durability without sagging even when a certain load is applied. Moreover, it is more preferable if it removes the existing heat insulation layer 3 and installs it instead, and has heat insulation. Therefore, specific materials include polystyrene foam, rigid urethane foam, phenolic foam, calcium silicate board, rock wool insulation board, composite panel, etc. Among them, polystyrene foam and rigid urethane foam having heat insulation properties. Phenol foam is most preferred.

Moreover, it is preferable to use the thing of 10-60 N / cm < ² > as the bending strength of the adjustment board 6 including the example of FIG. 1 and the example of FIG. If the bending strength is less than 10 N / cm ^2, it is not preferable because a sag occurs when a large load is applied. Conversely, if the bending strength exceeds 60 N / cm ² , a sag occurs. However, it is not preferable because the density increases and the heat insulation performance is inferior. The bending strength here is measured by JIS K 7221 “Bending test method for rigid foam plastic”.

The repair method of the present invention will be described step by step. First, in the case of the example shown in FIG. 1, the adjustment plate 6 is installed at a predetermined position on the existing waterproof sheet 2 and the heat insulating layer 3 therebelow, and the fixing plate 4 is further arranged from above. The fixed plate 4 is fixed to the base S by driving in.

Next, in the existing waterproof sheet 2 to be repaired and the heat insulating layer 3 therebelow, the place where the fixing plate 4 for fixing the new waterproof sheet 1 is arranged is removed. As the removing method, the existing waterproof sheet 2 and the heat insulating layer 3 may be removed separately, or both may be cut at once and removed at the same time. The adjustment plate 6 is placed in the recess thus formed so as to match the height of the existing heat insulating layer 3. Next, the fixing plate 4 is disposed on the adjustment plate 6 and driven and fixed to the ground by the anchor member 5.

Then, in either embodiment of Figures 1 and 2, the surface of the fixed plate 4 is coated with a bonding layer, superposed new waterproof sheet 1 thereon, established as shown in FIG. 3 By heating the fixed plate 4 from above the waterproof sheet 1 with the electromagnetic induction heater D, the fusion layer on the surface is melted and thermally bonded to the newly installed waterproof sheet 1. Laying the new laying fixed tarpaulin predetermined number as well in the entire region of the fixing plate 4 was placed new waterproof sheet 1 1 and new tarpaulin 1 by fusing is completed.

The existing waterproof sheet 2 and the newly installed waterproof sheet 1 that can be used in the present invention may be any waterproof sheet that is usually used for waterproofing sheets, and the material is not particularly limited, but ethylene propylene diene monomer (EPDM) , Rubbers such as butyl rubber, isoprene / isobutylene copolymer (IIR) and blends thereof, sheets made of synthetic resins such as polyurethane, polyethylene and polyvinyl chloride, and olefinic thermoplastic elastomers. Then, EPDM having excellent weather resistance and good rubber elasticity is preferable. The thickness is preferably in the range of 0.8 to 2.5 mm. Moreover, the width | variety of about 1-2 m is normally used. If the thickness is less than 0.8 mm, the waterproof sheet may be easily broken due to insufficient strength, and if it exceeds 2.5 mm, the step becomes large at the joint and the appearance may be deteriorated. Absent. In addition, it is also possible to use a material in which a reinforcing cloth made of glass fiber or polyester fiber is embedded in these rubbers to improve mechanical strength and dimensional stability.

  Examples of the existing heat insulating layer 3 include materials such as polystyrene foam, polyurethane foam, and polyethylene foam. Usually, a heat insulating material having a thickness of about 10 to 50 mm can be used.

In the present invention, the new waterproof sheet 1 is laid from the existing waterproof sheet 2 without removing the existing waterproof sheet 2. When the new waterproof sheet 1 is laid from the existing waterproof sheet 2 without removing the existing waterproof sheet 2, the existing waterproof sheet 1 is installed. There is a problem that chemical components from the sheet 2, for example, tar components in the asphalt sheet and plasticizer components in the vinyl chloride sheet migrate to the newly installed waterproof sheet 1 and deteriorate.

  Therefore, as shown in FIG. 4, an insulating sheet 7 made of a thermoplastic resin film or the like can be integrated on the lower surface of the newly installed waterproof sheet 1 (the side in contact with the existing waterproof sheet). By doing so, the chemical component from the existing waterproof sheet 2 can be blocked from moving to the new waterproof sheet 1 side, and the new waterproof sheet 1 can be protected.

The insulating sheet 7 to be laminated and integrated includes polyethylene, polypropylene, ethylene vinyl acetate, ethylene methyl acrylate, ethylene methyl acrylate, etc., olefin resins, modified olefins such as chlorinated polyethylene, chlorinated polypropylene, maleated ethylene vinyl acetate, etc. Resins, olefinic thermoplastic elastomers, and the like can be used, and sheets of 50 to 500 μm thickness, more preferably 150 to 250 μm are laminated. If the thickness is less than 50 μm, the strength due to heat fusion decreases due to the insulating sheet 7 not being aligned with the pattern on the surface of the sheet, and if it exceeds 500 μm, the newly formed waterproof sheet is caused by the difference in thermal shrinkage with the existing waterproof sheet 2. 1 is not preferable because a large warp is generated in 1 and the pliability of the newly-installed waterproof sheet 1 is lost and it becomes difficult to follow the base or workability is deteriorated.

  As a method of laminating and integrating the new waterproof sheet 1 and the insulating sheet 7, a method using heat fusion or an adhesive may be considered. However, by heat fusion, it can be firmly laminated and integrated. . Specifically, the new waterproof sheet 1 and the insulating sheet 7 can be laminated and integrated by heat fusion by heating and pressurizing with a heat roll or the like. Further, in the heated state shortly after vulcanizing the new waterproof sheet 1, the insulating sheet 7 is laminated and fused using the heat generated when the new waterproof sheet 1 is vulcanized.

  Specifically, using an apparatus as shown in FIG. 5, an unvulcanized rubber sheet extruded from an extruder (not shown) is placed on the endless belt 21 and a predetermined temperature (150 to 200 ° C.) from the introduction roll 22. Insulating sheet 7 is laminated and integrated with pressure contact roll 26 via a plurality of guide rolls sent out from vulcanization can 23 through derivation roll 24 and vulcanized. Then, it is wound around the winding roll 29 via the tension roll 28.

  At this time, the new vulcanized rubber waterproof sheet 1 just sent out from the vulcanizing can 23 has a surface of 130 to 150 ° C., and the thermoplastic sheet can be easily fused.

In order to ensure the fixing of the newly installed waterproof sheet 1 to the base, the fixing plate 4 is arranged at a predetermined interval. The number of the fixing plates 4 to be arranged is not particularly determined depending on the state of the ground S, but it is necessary to be sufficiently fixed to the ground S so as not to be lifted by the influence of wind or the like. Usually evenly arranged with 1-4 / m ² range of about.

  The fixing plate 4 of the present invention is made of a metal such as stainless steel, galvanized steel plate, galvanium steel plate, hot dip aluminum plated steel plate, cold rolled stainless steel plate, aluminum plate, aluminum alloy plate, fiber reinforced resin, or the like. It has a shape such as a circle, a square, or a rectangle with a diameter of about φ60 to 100 mm.

  The thickness of the fixing plate 4 varies depending on the type of metal used, but a thickness of about 0.4 to 2.0 mm is usually used. If the thickness is less than 0.4 mm, the rigidity is low, and if it exceeds 2.0 mm, the workability becomes poor and the weight increases. In particular, when stainless steel is used, a thickness of 0.5 to 1.0 mm is most preferable. If it is stainless steel, sufficient rigidity can be obtained in this range, and it can be easily cut with a metal cutting scissor, and the processing at the time of construction is also easy.

Moreover, as an adhesive used for bonding the existing waterproof sheet 2 and the new waterproof sheet 1 and the base S or bonding the existing waterproof sheet 2 and the new waterproof sheet 1, chloroprene rubber, butyl rubber or other additives may be used in a solvent or water. A melted adhesive can be used.

  The present invention is a method for renovating insulation waterproofing that can be laid from the top without removing the existing waterproofing layer and heat insulation layer when renovation work is performed in accordance with the deterioration of the waterproof layer applied to the rooftop in a building or the like. Or it can be used as a structure.
