 According to the present invention, when the PE sheet is fused to a sheet for attaching a plurality of sheets attached to a wall of a water tank made of a concrete structure to form a waterproof layer of the water tank, the PE sheet is detached from the wall due to a decrease in adhesion force of the sheet for attaching to the wall. It relates to a waterproof method and structure of the water tank using a PE sheet that can be prevented.

 In general, the water tank installed in the basement or roof of the building is usually made of a concrete structure, the waterproofing of the inner surface is essentially required due to the nature of the water contained.

Conventionally, the heat-treatment method was mainly applied to the inner surface of a water tank made of a concrete structure by using a thermosetting resin mainly composed of epoxy resin or glass fiber as a reinforcing material, but this was not only permanent but time-consuming, and wasted. There was a problem causing inconvenience.

Accordingly, in recent years, a waterproof structure using a polyethylene sheet (PE sheet) has been proposed as shown in FIGS. 1A and 1B. In general, the reservoir 110 is made of a concrete structure as described above, and has a substantially rectangular shape. Each wall surface 111 and the bottom surface 112 and the ceiling surface 113 formed in the lateral direction formed by the enclosure is formed, the one side wall 111 through the sleeve 114 penetrates the inner and outer In addition, both the wall 114, the bottom 112, and the ceiling surface 113 including the sleeve 114 are attached to the PE sheet 130 to be waterproof.

In addition, the reservoir 110 may have a wall protrusion pillar 116 formed on the wall surface 111 due to the structural limitation of the building, and the square pillar 117 may be formed at the center or the outer portion thereof. Protrusion pillar 116 and the square pillar 117 is also waterproof by the PE sheet 130, and as shown in Figure 1a is a variety of installations, for example, ladder 115 is installed inside the reservoir 110, The ladder 115 has a structure in which height can be adjusted up and down in general, and the upper and lower end sides are fixed to the ceiling surface 113 and the bottom surface 112 of the water tank 110 so as to be fixed.

7 is a cross-sectional view showing a waterproof structure by a conventional PE sheet, as shown in the PE sheet 130 is supplied along the inner surface of the reservoir 110, the base surface treatment, washer 140a overlapping each other ) Is inserted into the tableting nail 140 inserted into the PE sheet 130 and fixed to the PE sheet 130. In order to prevent corrosion of the tableting nail 140 according to water contact, the outside of the fixing part is added to the sheet 150. It was fused and concealed.

In addition, as another example, as shown in Figure 8, the bonding sheet 160 having a predetermined area on the inner surface of the base surface treated reservoir 110 is combined with the tableting nail 140 with the washer 140a is inserted into the reservoir After hitting and fixing to be arranged at a predetermined interval on the inner surface of 110, the method for heat-bonding the PE sheet 130 to the sheeting sheet 160 so that the sheeting sheet 160 is located approximately at the center portion. It has been proposed.

However, the conventional waterproofing method of the reservoir using the PE sheet is not only to cause damage to the concrete wall by the momentary impact, but also to use the gun gun when the tableting nail is nailed to the concrete wall of the reservoir. Various complex factors, such as explosive force, small holes in the disassembly of firearms, and the strength of concrete, have made it difficult to secure solid support and uniform adhesion.

Therefore, the PE sheet has a problem in that the PE sheet adheres to the wall and the sustainability and stability of PE sheet adhere to the wall by repeatedly contracting and expanding according to the temperature difference of the water or when the pressure is changed due to the change of the storage capacity.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, its purpose is to fuse the PE sheet to the sheet for attaching a large number along the wall surface of the reservoir made of a concrete structure to form a waterproof layer of the reservoir At this time, the PE sheet is to be prevented from being separated from the wall due to the deterioration of the adhesion of the sheet for attachment to the wall.

In addition, an object of the present invention is to ensure a stable fusion of the PE sheet to the sheet for attaching the sheet for gluing, even without a highly skilled technique.

2 is an exploded perspective view showing the configuration of the apparatus of the present invention.

As shown therein, the present invention is provided with a fixed anchor (1) that is inserted and fixed by hitting the sheet attachment hole (117b) formed on the inner surface of the reservoir by a drill drilling operation, the fixed anchor (1) is made of plastic Consists of a blow anchor.

More specifically, the fixed anchor 1 is a plastic anchor member 10 that is substantially inserted into and fixed to the inner surface of the water tank made of a concrete structure, that is, the seat attachment hole 117b formed on the wall surface 117a. And a bolt 20 inserted into the anchor member 10 to expand an end side of the anchor member 10 by hitting and fixing the anchor member 10 to the inside of the seat attaching hole 117b. It consists of.

To this end, the anchor member 10 having a tubular shape having an opening 11 at one side includes a slit 13 at the other side of the opening 11, and has a wall surface at an outer surface on which the slit 13 is formed. In order to increase the frictional force with the inner surface of the sheet attachment hole 117b of the 117a, the uneven portion 12 is formed along the circumference.

In addition, the anchor member 10 is connected to the end of the bolt insertion hole 14, the inner side as shown in Figure 3 so that the end side can be expanded around the slit 13 at all times when the bolt 20 is hit. A taper 15 is formed, and the opening 11 is configured such that the anchor washer 2 and the attaching sheet 3 fitted to the outside with a slightly larger diameter are not caught and detached from the sheet. It is natural to form an anchor through hole 3a through which the anchor member 10 can pass.

Then, the bolt 20 is formed of a metal material as usual, and inserted into the anchor member 10 by a blow from a predetermined position of the middle portion to the end portion, and then separated from the anchor member 10 again. The spiral part 22 is formed so that it may be easily performed, and it isolate | separates by rotating by inserting a screwdriver into the groove formed in the bolt head 21, and rotating.

The fusion of the PE sheet 130 to the gluing sheet 3 fixed to the wall surface 117a of the water tank by the fixing anchor 1 is performed by high frequency induction heating, and for this purpose, a high frequency fusion machine (not shown). Is used).

In general, when a permanent magnet is inserted and removed from the center of a coil-shaped conductor, the magnetic field changes and a current flows in the conductor. This is called an electromagnetic induction action, and high frequency induction heating uses this electromagnetic induction action to apply an alternating current to the coil instead of the permanent magnet. By causing alternating flux to flow, an induced current, i.e., an eddy current, flows to the heated object.

The induced current generates Joule heat by the eddy current loss, and heating with this generated heat is called induction heating. In this case, the characteristic of the eddy current is concentrated in the adjacent part of the object and the induced current flows strongly around the surface of the object. It is characterized by a weak flow inside the object.

This principle allows efficient rapid heating by concentrating energy on the required part of the object to be heated.
