Description

Method of manufacturing self-adhesive waterproof sheet and constructing self-adhesive waterproof sheet and self-adhesive waterproof sheet {auto cohesion type waterproof sheet production technique and auto cohesion type waterproof sheet and auto cohesion type waterproof sheet construction technique}

The present invention relates to a method for manufacturing a self-adhesive waterproof sheet, a method for constructing a self-adhesive waterproof sheet and a self-adhesive waterproof sheet, and in particular, manufactures a self-adhesive waterproof sheet having a tensile strength reinforced by laminating polyethylene twisted net and chloride sheet in a self-adhesive rubber compound. The present invention relates to a method of constructing a self-adhesive waterproof sheet and a self-adhesive waterproof sheet.

In general, the sheet waterproofing material is classified into asphalt sheet waterproofing material and bentonite sheet waterproofing material.

Asphalt-based sheet waterproofing material of the former has asphalt thickness as the main material, thickness 2.5mm-3.0mm, width 1m, length 10m, and unit weight per roll is 35kg / 10㎡, after arranging the base surface of the object, apply asphalt primer Afterwards, the asphalt-based sheet waterproofing material is melted and bonded with an LPG torch.

Asphalt-based sheet waterproofing material as described above has the following materials and construction problems.

First, the asphalt sheet waterproofing material is not flexible at low temperatures, there is a fear that the waterproof sheet is broken when spreading the roll for construction.

Second, the asphalt sheet waterproofing material is about 40 kg (10 m / pavement) of weight per roll of pavement, there is a problem that wastes a lot of manpower when carrying a relatively small amount.

Third, since the asphalt sheet waterproofing material is melted with an LPG torch and attached to the object, it is difficult to completely integrate with the object in the process of attaching the sheet waterproofing material.

Fourth, when the asphalt sheet waterproofing material is submerged in water for a long time there is a problem that the asphalt particles are diluted by water to cause water pollution.

Fifth, the asphalt sheet waterproof material has good elongation at high physical properties but little elongation at low temperatures, so fracture occurs during expansion and contraction of the structure.

Sixth, concrete is a water-soluble solid, and asphalt-based sheet waterproofing is an oil-based, so when the concrete is repeatedly moist and dry, relaxation occurs.

Seventh, the asphalt sheet waterproofing material has a problem inferior in workability because there is no flexibility at low temperatures in winter.

Eighth, if the asphalt sheet waterproofing material is melted with an LPG torch and heat is applied to the concrete surface during the attachment work, the concrete will collect on the hot side and the condensation will occur as it condenses on the concrete surface, causing condensation. Partial floating occurs.

Ninth, when the asphalt sheet waterproofing material penetrates into the seam of the seam or edge, and the groundwater penetrates into any part, the water vein is formed through the relaxed area of the asphalt sheet waterproofing material, and then the concrete crack, construction joint, and expansion joint And the phenomenon of leakage into the interior through the weak concrete parts such as material separation is repeated.

Tenth, when waterproofing the wall using asphalt sheet waterproofing material, the LPG torch must melt the asphalt sheet waterproofing material and attach it to the wall before the dishware.

On the other hand, the latter bentonite-based sheet waterproofing material is made of HDPE (High Density Polyethylene) film and volcanic dust as main materials, and has a thickness of 4.5 mm, width 1.2 m, and length of 7.5 m, and the unit weight per roll is about 44 kg / 9.0 m 2. After arranging the base surface of the, and then installed by installing a bentonite-based sheet waterproofing material with a concrete nail with a washer, the joint is characterized in that the construction by mechanical bonding using a thermal bonder.

Bentonite-based sheet waterproofing material as described above has the following materials and construction problems.

First, bentonite-based sheet waterproofing does not have any problem in waterproofing the bottom and upper layers, but in the wall waterproofing, when water flows into any one of the bentonite sheet waterproofing, the bentonite particles are swept down into the water and the upper part is not waterproof. Is generated.

Second, the volcanic dust that constitutes bentonite sheet waterproofing material has very weak material properties in seawater.

Third, since the bentonite sheet waterproofing method is attached to the concrete nails during construction, the bentonite sheet waterproofing material is attached while forming a hole in the waterproofing layer.

Fourth, the bentonite sheet waterproof material has a problem that the joint portion of the waterproof layer and the waterproof layer is not perfect.

Fifth, the bentonite sheet waterproof material is inferior in workability in winter construction because it is not flexible at low temperature of the physical properties of the HDPE film.
