Description

[0001] The present invention relates to a waterproof protective sheet having a waterproof function and a construction method using the waterproof layer,

The present invention relates to a waterproof layer protective sheet, and more particularly, it relates to a waterproof layer protective sheet, which prevents waterproof layer from being damaged by providing a waterproof layer on a waterproof layer without damaging or damaging the waterproof layer before the protective concrete A waterproof protective sheet having a waterproof function and a construction method using the waterproof protective sheet.

In general, waterproofing is applied to concrete structures such as the floor of a building, an underground outer wall, an underground parking lot upper slab, and a building roof, in order to prevent water from leaking into the interior. Here, the roof waterproofing on the roof or the upper part of the slab can be classified into a close adhesion method in which a waterproof sheet is adhered to the entire surface of the waterproof sheet and an insulation method in which a waterproof sheet is fixed to only a part of the base, The non-visible waterproofing method is a method of pouring protective concrete (free-flowing concrete) on the upper part of the waterproof layer. It forms a thermal insulation layer on the waterproof layer before installing the protective concrete. You may.

 However, waterproofing is carried out after the waterproofing process, when insulation construction and protection concrete pouring work are done on the waterproof sheet, it is waterproofed due to transportation and loading of various materials, movement of working tools and equipment, throwing of various tools and auxiliary materials, A local force and pressure are applied to the sheet, and the waterproof sheet is damaged or torn by the wire mesh, the metal fixing fixture, or the crush stone, and the waterproof layer is damaged and leakage occurs. Therefore, even if the waterproofing work is done perfectly, it is connected to a fatal leak by the above-mentioned cause.

Therefore, in order to prevent damage to such a waterproof layer in non-exposed waterproofing, protective mortar, PE foam protection material, PVC sheet, PE film and the like are installed between the waterproof sheet and the protective concrete layer as a waterproof layer protection material. Patent No. 624354 " "And Utility Model Registration No. 444931" Waterproofing Layer Protection Material ".

The protective mortar is a cement mortar that is finished by putting it on the top of the waterproof layer and finished with a trowel and machine finishing. It has excellent durability because of its good compression and impact strength. However, It is necessary to prepare the work for a long time. Since it is used by mixing with cement, sufficient curing is required after the protective mortar is applied, so there is a problem that it can not proceed to the concrete casting process.

PE foam protective material is a sheet-like product formed by foaming polyethylene resin and foamed. It absorbs shocks well because of its excellent buffering ability, but it must be adhered by front adhesive method, so when there is moisture and moisture on the upper part of waterproof layer, (Cushion), it causes cracks in the non-porous concrete layer. If the long-term internal load is applied, cracks are generated in the non-porous concrete layer.

The PVC sheet is basically flexible at room temperature but has a property of solidifying at low temperature, so that it is sensitive to temperature. In particular, recycled PVC is not uniform in quality because the raw materials are not mixed homogeneously. Therefore, the PVC sheet is severely bent according to the temperature or wrinkles occur when the sheet is spread. In a low temperature environment, the sheet is hardened and the wrinkles and bending phenomenon are further increased, There is a problem that it is difficult to ensure the uniformity of the surface.

On the other hand, since the PE film is soft, it has weak tensile and tear strength and is not effective for buffering action. Therefore, it is weak against external impact. When the film is stretched when the film is applied, the material stiffness is weak so that wrinkles and folding occur. There is a problem that it is necessary.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a waterproofing material, which is installed on an upper part of a waterproofing layer before a protective concrete A waterproof protective sheet having a waterproof function and a waterproof function as well as a good workability and a method of construction using the waterproof protective sheet.

In order to solve the above-mentioned problems, the waterproof layer protective sheet having a waterproof function according to the present invention comprises: a resin layer exposed on the top; A synthetic fiber aggregate sheet positioned at the bottom of the resin layer and made of any one of polyester, polypropylene, and nylon and having a weight per unit area of 50 to 300 g / m 2; And an adhesive layer formed by laminating the resin layer and the synthetic fiber aggregate sheet by applying a liquid polyethylene (PE) in a thickness of 0.025 to 0.05 mm and laminating the resin layer with a heat press roller, wherein the resin layer comprises a polypropylene , A polyethylene (PE) resin, and an ethylene-vinyl acetate (EVA) resin, or a PET film.

Preferably, a polypropylene (PP) or polyethylene (PE) saddle is further inserted between the resin layer and the synthetic fiber aggregate sheet.

A method of applying a waterproof layer protective sheet according to the present invention comprises the steps of: constructing a waterproof layer on an upper surface of a concrete base; Providing a waterproof layer protective sheet on the waterproof layer; And a protective concrete (non-woven concrete) is placed on the top of the waterproof layer-protecting sheet.

Preferably, at the time of installing the waterproof layer protective sheet, the adjacent waterproof layer protective sheet is abutted and then taping treatment or waterproof layer protective material is placed on the abutted portion so as to overlap with each other by 20 to 50 mm, Or a waterproof layer protective sheet is attached and then a layer of a film or adhesive is applied to a portion to be overlapped and then a waterproof layer protective sheet is stacked and attached.

Preferably, when the waterproof layer-protecting sheet is provided, the waterproof layer-protecting sheet is partially fixed after partially applying an adhesive or a coating agent to the surface of the waterproof layer.

Preferably, the waterproof layer is formed by waterproofing the coating film, and the waterproof layer is provided by integrating the waterproof layer and the waterproof layer protective sheet by providing a waterproof layer protective sheet before the waterproof layer is cured.

When pouring protective concrete (unfaced concrete) on the top of the waterproof layer from the non-exposed waterproof, it is necessary to locally apply force and pressure to the waterproof sheet by impact due to transportation, loading and throwing of various materials or auxiliary materials, And the waterproof sheet is broken or torn due to wire mesh, metal fastening steel or crush stone, etc., and the waterproof layer is already applied and damaged to damage the waterproof layer, resulting in water leakage. Since the protective sheet is installed on the top of the waterproof layer before the protective concrete is laid, it prevents the waterproof layer from being damaged or damaged due to the above-mentioned cause, thereby safely protecting the waterproof layer. The waterproof layer protective sheet itself has a waterproof function Not only that, but also the workability is very good.

1 is a view showing a first embodiment of a waterproof layer-protecting sheet according to the present invention.
2 is a view showing a second embodiment of the waterproof layer-protecting sheet according to the present invention.
3 is a view showing a state in which the waterproof layer protective sheet according to the present invention is installed.
Fig. 4 is a flowchart for constructing a waterproof layer protective sheet.

The most significant technical feature of the waterproof layer-protecting sheet according to the present invention is that it provides a waterproof layer-protecting sheet which protects the waterproof layer without damaging or damaging it when the protective concrete (impervious concrete) is laid in the non-exposed waterproofing, .

The waterproofing layer protective sheet 10 or 10 'according to the present invention is installed on the waterproofing layer 30 formed on the base surface 20 of the concrete structure and is positioned between the waterproofing layer 30 and the nonmagnetic concrete 40, The adhesive layer 12 and the synthetic fiber aggregate sheet 13 are stacked in this order from the top.

The resin layer 11 has a smooth surface and is exposed on the upper surface. The resin layer 11 may be made of polypropylene (PP) resin, low-density polyethylene (LDPE), or linear low-density polyethylene (LLDPE) Polyethylene (PE) resin such as high-density polyethylene (HDPE) or ethylene vinyl acetate (EVA) resin, or PET (polyethylene terephthalate) 10), and it is preferable to use HDPE for strengthening impact resistance.

The synthetic fiber aggregate sheet 13 is located at the lower portion of the resin layer 11 and is made of any one of polyester, polypropylene and nylon and has properties such as thermal insulation, impact resistance, weather resistance, dimensional stability, . Further, when the synthetic fiber aggregate sheet is adhered to the high-density polyethylene film, the tensile strength and the tearing strength are improved, thereby improving the physical properties of the waterproof layer as a protective sheet.

The synthetic fiber aggregate sheet (13) can be used without limitation in both short fibers and long fibers, and the weight per unit area is preferably 50 to 300 g / m 2. If the weight is less than 50g / ㎡, it may lose the effect of buffering effect due to insufficient heat insulation and compressibility, and the overall weight may be low, which may cause wind to be blown upon installation on the base surface. If the weight is 300 g / m < 2 > or more, the function and workability can be improved, but the price is inferior.

The adhesive layer 12 is formed by laminating the adhesive layer 12 with a heat press roller while applying a liquid polyethylene (PE) serving as an adhesive in a thickness of 0.025 to 0.05 mm in the production apparatus to adhere the resin layer 11 and the synthetic fiber aggregate sheet 13, . A polypropylene (PP) or polyethylene (PE) saddle 14 is further inserted between the resin layer 11 and the synthetic fiber aggregate sheet 13 while the resin layer 11 and the synthetic fiber aggregate sheet 13 are adhered to each other The tensile strength and the tear strength of the protective sheet are significantly reinforced and are not torn.

The waterproof layer protective sheet 10 and 10 'manufactured as described above are excellent in tensile strength, tear strength, punch resistance, impact resistance, and the like, and therefore, when installing the indifferent concrete 40, , The damage of the waterproof layer 30 due to crushing and the like can be minimized. Further, since the liquid polyethylene is coated and integrated with a thickness of 0.025 to 0.05 mm in the course of integrating the high density polyethylene film and the synthetic fiber aggregate sheet, The cracks are not transmitted to the waterproof layer 30 even if cracks occur in the concrete layer 40 due to external force or impact after concrete curing.

When liquid polyethylene is sprayed onto the lower portion of the synthetic fiber aggregate sheet 13 adhered to the lower portion of the waterproofing layer protective sheet 10 or 10 ', moisture can be prevented from being absorbed or penetrated into the protective sheet , It will be able to more effectively function as a protective sheet with waterproof function and watertight protection function.

In addition, even if an impact is applied from the upper part after the application, the lower synthetic fiber aggregate sheet 13 will buffer the shock, minimizing the damage to the waterproof layer 30 and spreading the waterproof layer 10, 10 ' It is excellent in workability because it acts as a pull to prevent wrinkles from being knocked down on the upper part of waterproof layer due to dimensional stability and constant weight securing at installation.

A method of constructing a waterproofing layer protection material according to the present invention comprises the steps of: (S1) installing a waterproof layer on a concrete base surface; (S2) installing a waterproofing layer protective sheet on an upper part of the waterproofing layer; (S4) of pouring concrete (non-woven concrete). In the case of waterproofing with external heat insulation, the step S3 may be performed before the protective concrete (non-woven concrete) is laid. The waterproof layer 30 may be waterproofed by any method such as sheet waterproofing, film waterproofing or composite waterproofing.

The method of treating the connection portion of the waterproofing layer protective sheet 10, 10 'may be as follows. First, the adjacent waterproofing layer protective sheet may be abutted and then taped to the abutting portion. Second, the waterproofing layer protective sheet may be laminated by 20 to 50 mm And then taping the end portion exposed to the outside after the installation. Alternatively, the protective sheet may be provided by applying a coating agent or an adhesive to the portion to be overlapped after the one side waterproofing layer protective sheet is provided, It can also be installed.

The method of providing the waterproofing layer protective sheet 10 or 10 'on the waterproofing layer 30 may be performed by partially applying an adhesive or a coating agent to an unspecified place on the surface of the waterproofing layer 30 and partially fixing the waterproofing layer protective sheet Second, a coating agent or an adhesive may be applied on the surface of the waterproof layer 30 with a roller spaced apart by a predetermined interval, and then the coating agent or adhesive may be placed at the bottom center of the waterproof layer 10, 10 '. In this case, the adhesion of the waterproofing layer protective sheet 10, 10 'and the waterproof layer 30 to the surface of the synthetic fiber aggregate sheet can be easily secured due to adhesiveness and the fiber strands of the synthetic fiber aggregate sheet.

On the other hand, in the case where the waterproof layer 30 is formed by waterproofing the coating film, since the synthetic fiber aggregate sheet 13 is located on the lower surface of the protective sheet when the waterproof layer 10, 10 'is provided before the waterproof layer is cured, The waterproof layer protective sheet 10, 10 'is adhered to the waterproof layer 30 while the fibrous assembly sheet and the coating material are easily integrated. Such a construction method can be very useful when it is applied to a wall formed in a vertical direction, and a method of applying a waterproofing layer protection material immediately before curing after applying a coating waterproofing material to a floor or a wall in a field requiring quick construction in the field condition is used .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention. Various modifications and variations will be possible without departing from the spirit of the invention. Therefore, the scope of the present invention should be construed as being covered by the scope of the appended claims, and technical scope within the scope of equivalents thereof should be construed as being included in the scope of the present invention.
