本発明は、通気用テープ及びその施工法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation tape and a method for applying the same.

とするものである。Therefore, the present invention provides a ventilation tape between the waterproof coating layer and the base slab to ventilate air, water vapor, etc. that accumulates between the waterproof layer and the base slab to the outside air. This is related to tape, and for the purpose of adhering and fixing the ventilation tape base material l to the base slab surface, an adhesive layer is provided in advance in a grid pattern on the tape surface, and the adhesive layer is applied to the area of the tape base material. The area occupied by the adhesive layer is 3 times to 3 times.
Ventilation gap 3 in the range of 0 ratio, residual glue j to 70 ratio
When the waterproof layer is formed by covering the tape with a waterproof coating layer, the upper surface of the tape is brought into close contact with the waterproof coating layer.

しば発生する。Conventionally, concrete base slabs have been found to contain excess moisture other than the water required for cement crystallization, and moisture has been added to the concrete base slabs due to rain, snow, dew, etc. before the waterproof coating is applied. It is inevitable that such a layer exists, and if a waterproof coating is applied to such a concrete base slab using the normal method, the temperature will rise due to radiant heat from the sun after the waterproofing layer is installed. At this time, water present in the concrete base slab becomes water vapor and evaporates and expands between the concrete base slab and the waterproof coating, often causing a significant blistering phenomenon in the waterproof layer.

は必ず防水層にふくれ現象が発生する事は事実である。Various construction methods have been tried and implemented to prevent the blistering phenomenon of the waterproof coating layer at this size. However, there is no decisive factor in preventing blistering, and there is no choice but to use insulation methods, etc.
Partial floating construction methods, etc. have been used in the past, but when waterproofing coatings are applied to rain, snow, wire diameter, or when the waterproofing coating layer is installed when the concrete base slab is insufficiently dry, waterproofing is always required. It is a fact that a blistering phenomenon occurs in the layer.

止している。The present invention aims to provide a luminous ventilation tape that solves the drawback of the blistering phenomenon that could not be prevented in the past. Because the ventilation tape is interposed between the layers, when the remaining water vaporizes, the water vapor passes between the ventilation tape and the base slab surface and releases the outside air before the waterproof coating layer swells. The purpose of the present invention is to provide a ventilation tape and a method for constructing the ventilation tape for keeping the swelling pressure of water vaporized at the same pressure as the outside air pressure. A feature of the present invention is that the ventilation tape and the waterproof coating layer are brought into close contact with each other, and a gap of 5 to 70% is provided between the ventilation tape and the concrete base slab, allowing gas to pass through. Since the ventilation tape and the waterproof coating layer are in close contact with each other, it is possible to prevent water vapor from stagnating between the waterproof coating layer and the ventilation tape and causing a blistering phenomenon.

施工作業に手間が掛る欠点がある。It is preferable that the ratio of the area occupied by the tacky adhesive layer in contact with one side of the tape base material 1 in a lattice pattern is in the range of j to 30%. This is because when creating a ventilation gap,
If the adhesive strength of the adhesive fixed to the waterproofing base is weak, there is a drawback that the waterproofing coating construction work is time-consuming.
