The present invention relates to a waterproof sheet, a mechanization apparatus for constructing a waterproofing layer, and a waterproofing method using the same, in which a base is provided, and more specifically, to form a waterproofing layer for waterproofing a base surface of a roof (slab) of a building structure. The present invention relates to a waterproof sheet provided with a base that can more easily discharge moisture from a base surface, a mechanization device for easy waterproof layer construction, and a waterproof method using the waterproof sheet and the mechanical device.

Typically, the base of the inorganic material such as concrete or mortar forming the building structure is leaked and condensation that plays a role of promoting the aging of the building by weakening the durability of the building due to the crack. Therefore, in order to eliminate the cause of such defects, the building structure such as slab (roof), retaining wall, sandwich panel roof of building and slab and retaining wall of civil engineering structures are exposed to moisture. In order to prevent this, it is common to perform waterproofing to form an impervious waterproofing layer on the surface. Various types of construction methods related to the roof waterproofing construction have been proposed and used to meet the waterproofing purpose. As a method of forming a waterproofing layer for waterproofing the exterior of a building, for example, a sheet waterproofing method using a waterproof sheet, a waterproofing coating material The coating film waterproofing method using this, and the composite film waterproofing method using the sheet | seat and the coating film together, etc. are used.

However, recently, among the various waterproof methods described above, the sheet waterproof method, which is a method that can simplify the waterproof construction and greatly shorten the construction period, is mainly used. This method uses the waterproof sheet as the bottom surface of a structure such as a roof of a building. Sheet waterproofing method of attaching to and forming a waterproof layer is widely used. The sheet waterproofing method is to spread the waterproof sheet of a certain standard, such as synthetic rubber or resin sheet or rubberized asphalt sheet having excellent elasticity to the floor surface of the construction structure such as the roof of the building.

However, when the sheet waterproofing or urethane coating waterproofing is applied for the waterproofing of the slab of the new building or the old slab as described above, the waterproofing layer is lifted or cracked due to the moisture of the base surface, thus to prevent such defects. Generally, an air vent is installed to discharge moisture from the base surface. The debase 11 is installed to protrude about 20 to 30 cm into the flat slab surface 100 as shown in FIG. 6. It was common to be. On the other hand, in order to further improve the general de-base, for example, Korean Patent Application No. 2003-0012958, "Moisture by installing a degassing means in the slab including a heat insulation layer, a mortar layer on the top surface of the concrete or mortar treatment A degassing apparatus of a building forcibly discharging moisture formed between layers due to a temperature difference between outside and outside air, the degassing means comprises: a plurality of first exhaust holes drilled in communication with the heat insulating layer from the mortar layer; A lower cover attached to the mortar layer by a sealing material to block water from flowing in, and having a plurality of second exhaust holes formed on a surface thereof, and a moisture discharge means attached to the second exhaust holes of the lower cover to discharge moisture in one direction; An upper cover spaced apart from an upper side of the lower cover and a fixed water penetrating the upper / lower cover and fixed to the bottom surface; The degassing apparatus of a building characterized by being a stage.

Stacked and discharged.

Next, a description will be given of the waterproofing method using the waterproofing sheet and the waterproofing layer construction mechanization device provided in accordance with the present invention.

3 is a schematic plan view schematically showing a process in which the waterproofing layer is constructed according to the present invention, Figure 4 is a cross-sectional side view of a building in which the waterproofing layer is constructed in accordance with the present invention, Figure 5 is a waterproofing layer in accordance with the present invention Side is a section of a broken building.

As shown in Figure 3, according to the construction method of the present invention, the surface of the PVC waterproof sheet 10 provided with a debase on the concrete surface of the rooftop slab bottom surface 100 to be installed is provided with a debase 11 Facing the bottom surface 100, and spread to spread the interval between each waterproof sheet 10 to about 1m, the edge of the waterproof sheet 10 with a concrete nail and sealant on the slab surface is fixed. Thus, the long fiber nonwoven fabric 23 is attached to one surface of the waterproof sheet 10 and the other surface of the waterproof sheet 10 faces the bottom surface 100 of the rooftop slab.

The interval between each sheet to install the PVC waterproof sheet 10 is installed while maintaining the interval so that the bottom surface 100 of the slab is more than 30cm every 2m of the width of the produced waterproof sheet. With this configuration, the long fiber nonwoven fabric 23 impregnated with a waterproofing functional material such as urethane resin can be adhered to the bottom surface 100 of the concrete slab matrix, and additionally, this part is used to maintain the waterproof layer. In the future, the non-woven fabric 23 waterproof layer acts as a partition wall to prevent damage when the water is spread to several places in case of partial damage by external force.

In addition, when constructing the long fiber nonwoven fabric 23 impregnated with the waterproofing functional material, when the coating film is applied to the nonwoven fabric with a urethane resin or the like by a conventional manual work, the flowable resin flows down, that is, self-leveling (self-leveling). ), The thickness of the waterproof layer is changed between the portion and the flat portion, such as the uneven portion of the floor, there is a disadvantage that the thickness of the waterproof layer is not constant. However, the hopper 22 and the nonwoven fabric 23 which can impregnate the nonwoven fabric 23 with urethane resin, water-soluble asphalt or rubber asphalt using the waterproofing mechanization apparatus 20 for construction according to the present invention can be guided constantly. The long-fiber nonwoven fabric 23 is integrated with the urethane resin while passing through the hopper 22 containing the urethane resin, and the moving part 25 such as a wheeled chassis is used. Covering the non-woven fabric 23 on the pre-installed PVC waterproof sheet while moving (in Figure 3, although the direction in which the PVC waterproof sheet is laid and the non-woven fabric laid in the direction orthogonal to each other to be constructed in the order of ① → ② → ③ Although not limited thereto, the above conventional problems may be solved because both may be constructed in the same direction in the longitudinal direction. That is, when the nonwoven fabric 23 impregnated with resin or the like is spread on the rooftop floor while moving the apparatus 20 by using the mechanized apparatus 20 for constructing the waterproof layer construction of the present invention, the nonwoven fabric 23 waterproof layer is completed, so that Not only can it be prevented from flowing down, but it can also be said to be a sacrificing method that saves construction time and reduces manpower. In addition, when the long-fiber nonwoven fabric 23 is spread on the floor using the waterproofing mechanization apparatus 20 of the present invention, the silica sand 211 is simultaneously 1 m 2 in the silica-containing hopper 21 installed on the upper portion of the apparatus 20. It is leaked so as to install 2 to 3kg per sugar and is coated on the upper surface of the nonwoven fabric. The silica sand layer thus formed has a function of protecting the nonwoven fabric. In addition, after completion of the application of the waterproofing functional material-impregnated nonwoven fabric, a methyl methacrylate resin is further applied thereon to prevent deterioration of waterproofing properties due to volatilization of a urethane resin or the like.

4 and 5, in the waterproofing method according to the present invention, both ends of the waterproof sheet 10 provided with the debase 11 have a predetermined length up to a predetermined height of the sidewall 110 surface installed on the floor railing to be installed. The nonwoven fabric 23, which is constructed to cover and impregnated with a urethane resin, extends from the bottom surface 100 to a predetermined height of the side wall 110 surface at or below the same height as or below the waterproof sheet 10 provided with the base. Apply to length.

Meanwhile, as shown in FIG. 5, the finish line 23a of the waterproof sheet 10 is covered on the finish line 23a of the PVC waterproof sheet 10 provided with the base of the sidewall 110.

Since the molding 30 is formed in this way, the moisture (W) is smoothly discharged in the direction of the arrow through the debase 11 of the PVC waterproof sheet 10 provided with the debase, but the rainwater is discharged to the debase 11. Block incoming

In particular, when the waterproof layer is generally formed by the conventional slab coating film waterproofing method, a situation occurs mainly when the bottom surface of the object to be coated has a waterproof layer that has been old. However, to remove the existing waterproof layer, noise, dust, waste, etc. were generated, resulting in many difficulties in operation. However, the construction method according to the present invention lays the PVC waterproof sheet provided with a degassing pipe to a width of about 1 to 2m as described above, and spaced about 30 cm or more between the sheets, so that only the nonwoven fabric 23 impregnated with resin etc. As the waterproof layer is bonded, it is possible to reduce the amount of work to be done three to four days because it cleans the surface of this part (removal of foreign substances on the floor) without having to clean the entire rooftop. Since the sheet layer completely blocks moisture from the floor, it can be installed directly on the floor even if there is a crack, moisture, or slight irregularities, and thus the floor cleaning cost can be reduced by more than 3000 won per 1㎡. , Even if there are cracks on the bottom surface, the fatigue phenomenon does not occur in the waterproof layer due to the sliding phenomenon in the sheet layer. Jininda.

As described above, the floor of the slab with the waterproof layer constructed in accordance with the present invention is completed by a flat PVC sheet rather than the conventional pipe type degassing pipe for moisture discharge, so there is no protrusion on the floor and the moisture outlet of the degassing pipe is Conventional problems, such as molding to the wall surface causing inconvenience to the operator has been completely solved.

In addition, in the present invention, the construction method is simple because the urethane resin, water-soluble asphalt or rubber asphalt, etc. are impregnated in the nonwoven fabric through a series of mechanization apparatus and at the same time moved through the apparatus configured to install silica sand thereon.
