BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing water from leaking out of concrete when an aluminum foam is poured into concrete, To prevent leakage of water in the concrete water.

In general, when a building such as an apartment or a building is to be expanded or contracted, a reinforcing bar for forming a wall and a ceiling slab is placed on a floor slab, an aluminum foam for forming a wall and a ceiling slab is formed, The aluminum foam is disassembled from the wall and ceiling slab, and the disassembled aluminum foam is moved to the upper layer while repeating the process of repeatedly carrying out the multi- To form the building of.

However, not only fine cracks are generated between the bottom slab and the aluminum foam forming the wall slab, but also the water of the concrete flows through the gap, resulting in contamination due to water leakage of the concrete, thereby deteriorating the beauty of the building, After the aggregate is exposed to the outside, the structural stability of the building is deteriorated and the durability and durability of the structure are reduced.

In addition, although the mortar is applied in order to close the gap between the aluminum foams forming the wall slab and the wall, when the aluminum foam is disassembled, the aluminum foam must be removed after the mortar is firstly removed, When the aluminum foam is detached without completely removing the mortar, there is a problem that the life of the aluminum foam is shortened due to the damage of the aluminum foam.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 is an exploded perspective view of the present invention, and Fig. 2 is a sectional view of the present invention.

An apparatus 100 for preventing water leakage of concrete according to the present invention comprises an aluminum foam 110 on which a support foil 111 and a vertical foam 112 are fixed by wedge pins 113 on an upper surface of a floor slab so as to form a wall of a building And the vertical foam 112 is adhered to the inner surface of the foam foam 111 in the longitudinal direction so as to protrude further than the end of the foam foam 110 on the inner surface of the foam foam 111, And a water leakage prevention part 120 for preventing water leakage of concrete by a gap between the floor slab 10 and the supporting foam 111 while being pressed by the load of the floor slab 110. More specifically, Respectively.

The water leakage preventing portion 120 is provided with a pressing member 121 which is pressed by the wedge pin 113 while being closely attached to the inner surface of the receiving foam 111 and is mounted on the bottom surface of the pressing member 121, And a water leakage preventing member 122 for preventing water leakage of the concrete while being in contact with the inner surface of the supporting foam 111 and the upper surface of the bottom slab 10 by the pressure of the pressurized fluid.

And a step 123 formed on an upper surface of the pressing member 121 to engage with the wedge pin 113. [

The waterproofing member 122 is preferably made of a material having elasticity without being damaged or deformed by the toxicity of the cement.

The separation guide 130 may further include a separating guide 130 formed at a lower end of the support 111 to allow the separating guide 200 to press the separating guide 130. The separating guide 130 may be curved desirable.

Hereinafter, the installation process of the present invention will be described.

3 to 4, the support foil 111 is seated on the upper surface of the floor slab 10 to form a wall of the building. The leakage preventing portion 120 is formed on the inner side of the support foil 111, And the water leakage preventing part 120 is seated on the upper surface of the floor slab 10.

When the support foil 111 is seated on the upper surface of the floor slab 10 to receive the leakage preventing part 120, the vertical foam 112 is seated on the support foil 111, Lifting either the vertical foam 112 or the backing foam 111 while the wedge pin 113 is engaged with the through holes 112 'and 111' penetrating through the backing foam 111, The wedge pin 113 is protruded from the through hole 112 'and 111' penetrating through the support foil 111 and the pin member 113 'is inserted into the through hole of the protruded wedge pin 113 (not shown) Lt; / RTI >

At this time, the end of the wedge pin 113 presses the upper surface of the pressing member 121 of the water-leakage preventing portion 120, and lifts the other side of the vertical foam 112 and the supporting foam 111, The wedge pin 113 is engaged with the through hole 112 'and 111' penetrating the foam 112 and the support foil 111 and then the protruded wedge pin 113 is inserted into the through hole (not shown) The wedge pin 113 presses the upper surface of the pressing member 121 and presses the upper surface of the aluminum foam 110 of the vertical foam 112 The leakage preventing member 122 mounted on the bottom surface of the pressing member 121 can be compressed by the load.

In this state, the vertical foam 112 is placed on the foam foam 111 and the wedge pin 113 is coupled to the vertical foam 112 and the through holes 112 'and 111' of the foam foam 111 The wedge pin 113 is fitted to the waterproof portion 120 while seating the aluminum foam 110 on the waterproof portion 120 after the waterproof portion 120 is seated on the upper surface of the floor slab 10 to form a wall of the building, 120 may be pressed against the upper surface of the pressing member 121.

Since the wedge pin 113 is caught by the step 123 formed to protrude or protrude from the upper surface of the pressing member 121 when the upper surface of the pressing member 121 of the leakage preventing portion 120 is pressed, The flow of the prevention part 120 can be prevented.

As shown in FIG. 5, when the aluminum foams 110 forming the walls of the building are formed while another vertical foam (not shown) is seated on the vertical foams 112 and fixed with the wedge pins The lower end portion of the supporting foam 111 is brought into close contact with the upper surface of the bottom slab 10 while the waterproof member 122 of the waterproof portion 120 is pressed by the load of the aluminum foam 110, Can tightly close the gap between the inner side surface of the support foil 111 and the upper surface of the bottom slab 10 to cure the concrete while safely preventing leakage of the moisture of the concrete poured into the aluminum foil 111.

The water leakage of the concrete does not flow down through the gap between the upper surface of the bottom slab 10 and the backing foam 111 by the leakage preventing member 122 and the occurrence of stains on the upper surface of the bottom slab 10 due to leakage of water of concrete So that the work process for removing stains formed on the upper surface of the floor slab 10 is shortened and the economy can be improved by reducing labor costs.

Here, the waterproofing member 122 is formed of a rubber material that is not damaged or deformed by the toxicity of the cement, and can be safely used.

When the concrete poured into the aluminum foam 110 is cured, the pin member 113 'is separated from the through hole (not shown) of the wedge pin 113 and the wedge pin 113 is separated from the vertical foam 112, The inner side of the base foil 111 and the bottom slab 10 are separated from the side walls while being separated from the through holes 111 'and 112' of the foam 111 and the vertical foam 112, Thereby separating the leakage preventing portion 120 which is in close contact with the upper surface.

After inserting the separating guide member 200 of a tool such as a paruru into the separating guide hole 130 at the lower end of the supporting foam 111 separated from the vertical foam 112 and the water leakage preventing part 120, , When the separating guide member 200 is pushed from the top to the bottom, the separating guide member 200 presses the separating guide 130 and the supporting foam 111 is separated from the side wall .

Here, the separating guide 130 may be formed to be inclined, but may be curved so that the separating guide member 200 can be easily pressed without being pushed.

The structure can be formed by repeating the process of moving the separated parts to the upper layer by the above process.
