Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

1 is a process diagram of a method of constructing an insulating sheet-coating film composite waterproof structure according to an embodiment of the present invention. Referring to FIG. 1, a method of constructing an insulating sheet-coated composite waterproof structure according to an embodiment includes a first step ST1, a second step ST2, and a third step ST3. For convenience, the insulating sheet-coating composite waterproofing structure and its construction method are described together.

In the first step ST1, the base surface 10 is arranged and the primer layer 20 is formed by applying a primer to the base surface 10. For example, the primer is formed of a polyurethane (PU) -based, urethane-based primer, and a synthetic resin primer may also be used.

In the second step ST2, a nonwoven fabric 30 partially including a non-permeable coating layer 31 is applied to the primer layer 20 on one side. That is, the nonwoven fabric 30 has a non-permeable coating layer 31 and a non-coated portion 32 on one surface thereof facing the primer layer 20. In the nonwoven fabric 30, the opaque coating layer 31 and the uncoated portion 32 may be formed in a predetermined pattern.

The opaque coating layer 31 may be formed on one surface of the nonwoven fabric 30 by a printing method. That is, the impermeable coating layer 31 may be formed by printing a trademark mark or an advertisement mark on the nonwoven fabric 30. Therefore, the manufacturing cost of forming the nonwoven fabric 30 and the impermeable coating layer 31 becomes low.

As an example, the nonwoven fabric 30 can be produced by a spun bond method using polypropylene (PP) as a main material. For example, the nonwoven fabric 30 may be formed by a method such as needle punching, meltblown, stitch bond, chemical bonding, thermal bonding, and wet- ≪ / RTI > The nonwoven fabric 30 may also be replaced with a synthetic nonwoven fabric (PET, nylon, viscose rayon), or a glass fiber nonwoven fabric.

The opaque coating layer 31 may be formed using a polyethylene (PE) resin as a main material. The impermeable coating layer 31 may be replaced with an urethane coating agent, an epoxy coating agent, an olefin coating agent, a PVC coating agent, a vinyl acetate resin coating agent, a hotmelt coating agent, a synthetic rubber coating agent, a silicone coating agent, an acrylic coating agent, an asphalt coating agent, .

FIG. 2 is a plan view of a nonwoven fabric used in the method of FIG. 1, and FIG. 3 is a cross-sectional view taken along the line III-III of FIG. 2 and 3, in a third step ST3, a liquid film-type waterproofing material is applied on the nonwoven fabric 30 to form a waterproofing layer 41, and the waterproofing material is impregnated into the nonwoven fabric 30, Film-waterproofing layer 40 is formed by the film-waterproofing layer 41 and the coating-film waterproofing layer 41.

The nonwoven fabric 30 is formed by forming a non-permeable coating layer 31 on the primer layer 20 and forming a non-permeable coating layer 31 on the opposite side of the primer layer 20, And is coated with a coating film waterproofing material. That is, the coating water-repellent layer 41 is not affected by the impermeable coating layer 31 and can be formed to have a uniform thickness on the nonwoven fabric 30. Therefore, deterioration of the durability of the coating film waterproof layer 41 can be prevented.

That is, when the nonwoven fabric 30 and the impermeable coating layer 31 are conventionally applied by perforating the sheet to apply the liquid film-coating waterproofing material, the nonwoven fabric 30 and the impermeable coating layer 31 are formed at the periphery of the perforation and perforation due to the flow- Thickness difference can be eliminated.

FIG. 4 is a cross-sectional view of an insulating sheet-coating film composite waterproof structure shown in an enlarged scale in FIG. 1; FIG. 1 and 4, in a third step ST3, a portion of the coating material waterproofing material impregnated with the nonwoven fabric 30 is blocked in the non-permeable coating layer 31, and the non-coated portion 31, (43) is attached to the primer layer (20) by a coating film waterproofing material filled in the primer layer (32).

When the opaque coating layer 31 and the non-coated portion 32 are formed in a predetermined pattern in the nonwoven fabric 30, the attachment portion 43 of the coating film waterproofing material filled in the non- To the primer layer 20 in the same pattern.

That is, the sheet-coating film waterproof layer 40 formed of the coating film waterproof layer 41 and the nonwoven fabric 30 is attached to the primer layer 20 in correspondence with the noncoated portion 32, Leaving the layer 20 in a floating state.

Further, when the opaque coating layer 31 and the non-coated portion 32 have a predetermined interval pattern, the attachment portions 43 are arranged at uniform intervals on the primer layer 20. Therefore, the phenomenon that the sheet-film waterproof layer 40 swells or floats from the surface 10 can be minimized.

The sheet-film waterproof layer 40 is not directly affected by the behavior and cracking of the base 10 and the structure as the base 10 and the primer layer 20 are spaced apart. Also, the sheet-film waterproofing layer 40 can disperse the water vapor pressure of the concrete forming the air pocket.

The liquid type coating film waterproofing material may be formed of a urethane rubber liquid type coating film waterproofing material. Also, the coating material of the coating film may be replaced with a liquid film-type waterproofing material such as rubber asphalt, acrylic rubber, urethane resin, hybrid urethane, unsaturated polyester resin, epoxy resin, urea resin and tar urethane.

Since the liquid-type coating film waterproofing material is coated on the nonwoven fabric 30 in the field, the coating waterproofing layer 41 is formed on the nonwoven fabric 30 while being impregnated into the nonwoven fabric 30. The nonwoven fabric 30 and the film waterproof layer 41 impregnated in the liquid film-type waterproofing material form a sheet-film waterproofing layer 40.

5 is a cross-sectional view of an insulating sheet-coating film composite waterproof structure showing an enlarged end portion where the nonwoven fabric is butted against each other. 5, a method of constructing the sheet-film composite waterproof structure at the end portions 301 and 302 connecting the nonwoven fabric 30 will be described.

In this case, the second step ST2 may further include the step of bonding the end portions 301 and 302 of the neighboring nonwoven fabrics 30 to each other to construct the primer layer 20. The second step ST2 further includes the step of attaching the tape 50 having the perforation holes 51 on the upper surface of the end portions 301 and 302 of the nonwoven fabric 30. The second step ST2 further includes the step of disposing the non-permeable coating layer 31 on the opposite side of the perforation hole 51 in the nonwoven fabric 30.

In the third step ST3, a liquid film-type waterproofing material is applied on the tape 50 in a state in which the tape 50 is attached to the end portions 301 and 302 to further form a film waterproof layer 41 on the tape 50 . At this time, a part of the coating film waterproofing material forming the coating film waterproof layer 41 is impregnated into the nonwoven fabric 30 through the perforation hole 51, and is blocked at the impermeable coating layer 31.

That is, the coating film waterproofing material is impregnated into the nonwoven fabric 30, adhered to the impermeable coating layer 31 provided on the bottom surface, and connected with the coating film waterproofing layer 41 through the perforation hole 51 of the tape 50 (C). The connection C of the coating film waterproofing material is formed in the same structure at the butt end portions 301 and 302 of the nonwoven fabric 30 and connected to each other at the end portions 301 and 302.

Since the coating film waterproofing material is blocked by the impermeable coating layer 31 and does not adhere to the primer layer 20, both ends 301 and 302 of the nonwoven fabric 30 are connected to each other by the tape 50 and the waterproof film layer 41 Therefore, elasticity is secured. Therefore, the stability at the joint portion of the tape 50 is improved. That is, the end portions 301 and 302 connecting the nonwoven fabric 30, can be prevented from being broken.

The water-repellent layer 40 is formed on the surface of the non-woven fabric 30 in such a manner as to connect the end portions 301 and 302 of the nonwoven fabric 30 to the nonwoven fabric 30, 20 in the state shown in Fig. That is, the sheet-coating film waterproofing layer 40 can effectively cope with the cracks and the behavior of the substrate 10 even at the end portions 301 and 302 of the nonwoven fabric 30 to which the sheet is adhered.

For example, the tape 50 may be formed with an adhesive on the synthetic perforated nonwoven fabric, and may be replaced with a synthetic nonwoven fabric. The waterproof layer 41 on the tape 50 is formed integrally with the waterproof layer 41 on the nonwoven fabric 30 because the waterproofing material is impregnated with the tape 50 and the nonwoven fabric 30.

Referring to FIG. 1 again, in the third step ST3, when applying the sheet-coating composite waterproofing structure to the exposed structure, the top coat layer 42 is further formed by applying a top coat coat on the coat coat waterproof layer 41 . In this case, the top coat layer 42 may have an ultraviolet shielding function.

When the upper surface finishing material layer 42 is applied to a pedestrian, the upper surface finishing material layer 42 may be coated with silica sand before curing, so that the upper surface finishing material layer 42 may have a slip prevention function by coming out of the silica sand on the coating waterproofing layer 41. When the sheet-coating composite waterproofing structure is applied to an unexposed structure, the topcoat layer may not be applied.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
