First, a method of constructing a crack-proof waterproof flooring structure on a concrete base material including cracks or cracks expected is described below with reference to FIGS. 2 to 10. FIG. 2 is a flowchart illustrating a method of constructing a crack-proof waterproof flooring structure on a concrete base material including a crack or a part to be cracked according to the first embodiment of the present invention. 3 to 10 are views showing each step according to the construction method of FIG.

First, as shown in Figure 3, in step S81 to remove the foreign matter present on the concrete base material 10. For example, an air gun or a vacuum cleaner is used to remove foreign substances present on the concrete base material 10. In particular, the foreign matter present in the portion 12 is expected to crack or crack on the concrete base material 10.

Next, as shown in Figure 4, in step S83 by applying a primer on the concrete base material 10 to form a primer layer (20). In this case, a transparent coating material for urethane undercoat may be used. For example, “Super Deck 100”, “Super Deck 101”, “Super Deck 110” or a corresponding paint of Samhwa Paint Industry Co., Ltd. may be used.

Next, as shown in FIG. 5, in step S85, a crack or crack of the concrete base material 10 is expected to be filled with a polymer resin for reinforcement to form a reinforcement part 30. The reinforcement part 30 is formed of a polymer resin for reinforcement so that the upper surface is substantially the same as the upper surface of the primer layer 20 on which the reinforcement part 30 is not formed. Fill in part 12. In this case, fast curing polyurea may be used as the polymer resin for reinforcement. For example, “Super Deck UR-290” of Samwha Paint Industry Co., Ltd. or a corresponding paint may be used.

Next, as shown in FIG. 6, the first adhesive tape 40 is attached to cover the reinforcement part 30 in step S91. Here, the first adhesive tape 40 blocks direct contact between the portion 12 of the concrete base material 10 that is expected to be cracked or cracked, and the elastic intermediate layer to be formed on the primer layer 20. In addition, the first adhesive tape 40 is generated in the concrete base material 10 as an elastic intermediate material layer to be formed on the primer layer 20 by inducing and dispersing stress generated by cracks generated in the concrete base material 10 in the horizontal direction. It is possible to suppress the transfer of stress due to cracks. In this case, as the first adhesive tape 40, an adhesive tape having colored flexibility may be used. For example, paper, cloth, plastic film, or the like may be used as the material of the first adhesive tape 40. Cellophane, PVC, vinyl, acrylic, polyimide, polypropylene, polyethylene and the like may be used as the material of the plastic film. The first adhesive tape 40 may be one surface or double-sided adhesive tape, of course, the adhesive layer is formed on the surface facing the concrete base material 10 side.

In the process of attaching the second adhesive tape 60, the elastic intermediate material layer 50 provides visibility to the first adhesive tape 40, so that the operator may perform elastic elasticity of the region to which the first adhesive tape 40 is attached. The second adhesive tape 60 can be easily attached onto the backing layer 50. At this time, the second adhesive tape 60 is elastically by inducing and dispersing the stress transmitted from the elastic adhesive material layer 50 under the second adhesive tape 60 in the same direction as the first adhesive tape 40. The finishing material to be formed on the middle material layer 50 serves to block the transfer of stress due to the crack generated in the concrete base material 10 once again. In this case, the second adhesive tape 60 may use a material used as the first adhesive tape 40 as it is, and it is preferable to use an adhesive tape having a different color so as to be distinguished from the first adhesive tape 40.

At this time, the second adhesive tape 60 is attached on the elastic intermediate material layer 50 to which the first adhesive tape 40 is attached, and is attached to a position corresponding to the position where the first adhesive tape 40 is attached. The second adhesive tape 60 may be attached on the elastic intermediate material layer 50 to cover substantially the same area as the first adhesive tape 40, or may be attached to cover an area where the first adhesive tape 40 is formed. .

Then, as shown in Figure 9, in step S97 by applying a finish on the elastic intermediate material layer 50 to form a finish layer 70. In this case, polyurea may be used as the finishing material, for example, "Super Deck U-285", "Super Deck H-275", "Super Deck H-290", "Super Deck US-290", "Samhwa Paint Industry Co., Ltd." Superdeck US-291 ”,“ Superdeck UB-255D ”,“ Superdeck U-240D ”or equivalent paint may be used.

As shown in Figure 10, by forming a non-slip layer 80 on the finish layer 70 in step S99, to complete the construction of the crack-proof waterproof flooring structure 100 according to the present invention. That is, the anti-slip layer 80 may be formed by dust spraying the spherical silica sand and the polyurea on the finish layer 70. As spherical siliceous sand, an average particle size of 20 to 60 mesh, a morse hardness of 5 or more, and a silicon sand processed into a spherical shape without an angle may be used.

At this time, when constructing the crack-proof waterproof flooring structure 100, the anti-slip layer 80 may be selectively formed, for example, when used as a warning line or a car parking lot flooring.

And, as shown in Figure 10, when the construction of the crack-proof waterproof flooring structure 100, in the case where the construction site is exposed to direct sunlight to the external exposure site to give a long-term weather resistance, finish finish in step S101 Layer 90 may be formed. The finish top coat layer 90 may be formed to cover the finish layer 70 and the anti-slip layer 80. The finishing material may be a weather resistant elastic polyurethane top coat or a fast curing polyurea top coat, for example, "Super Deck 300", "Super Deck 301" of Samwha Paint Industry Co., Ltd. or a corresponding paint may be used.

Referring to FIGS. 11 and 12, a process of generating a crack 14 in the concrete base material 10 on which the crack-proof waterproof flooring structure 100 is constructed according to the first embodiment is as follows.

11 and 12, even if the crack-proof waterproof flooring structure 100 according to the first embodiment is constructed on the concrete base material 10, the crack 14 is cracked again at the portion 12 where cracking or cracking is expected. ) May be generated.
