It is done in the order of installation.

At this time, the thermal insulation work for placing lightweight foam concrete, the heating work for piping hot water pipes for heating, and the plastering work for plastering the floor are all performed in a wet process. Moisture also occurs during concrete hardening.

Such moisture causes odors and molds to corrode various decorative materials of the building, and causes cracking and peeling of slab concrete, resulting in deterioration of stability of the structure.

Therefore, in recent years, there is a trend to construct a lot of ventilation panels that can effectively remove moisture, such as to quickly evaporate and drain the moisture concentrated in the upper surface of the slab and the moisture generated during the slab concrete curing process to the outside.

For example, Korean Patent Publication No. 10-0945266 discloses a ventilation panel for drying a slab.

The slab drying ventilation panel is a combination of a vertical panel and a horizontal panel. The slab drying ventilation panel is configured to rapidly evaporate and discharge moisture accumulated in the center of the slab to contribute to the reduction of air and the durability of the structure. .

Referring to FIGS. 2 to 6, in step S10, a pair of vertical panels 12a and 12b abut on the first bent portion 18 and are stacked in two layers, and a plurality of cups protruding inward of each layer. The air passage 10 in the vertical direction is formed by the one-to-one contact with each other in a one-to-one relationship, and the second bent portion 23 formed at one end of the pair of vertical panels 12a and 12b is formed. The horizontal panel is bent in a “c” shape to prevent the open ends of the vertical panels 12a and 12b from facing each other, and the horizontal panel extends toward the bottom of any one of the vertical panels 12a and 12b. A plurality of cups 11b protruding toward the bottom in contact with the bottom by bending 15 at right angles are formed so as to maintain a gap between them.

Ventilation panel according to the present invention as described above is made of a combination form of the wall panel 16 and the floor panel 17, each panel is spaced close to the wall side and the floor while being a space for air passage It is to be formed, it is installed in a structure that can quickly remove the moisture on the top of the slab through the space is so formed.

The wall panel 16 is installed along a portion where the wall and the floor are in contact with each other, that is, the edge portion where the wall and the floor are connected, and the two overlapping vertical panels 12 and 12b and the horizontal panel 15 bent toward the floor. ) Is made in one piece.

The vertical panels 12a and 12b are folded in a horizontal direction by using the first bent portion 18 at one side end and then overlapped in two layers through the second bent portion 23 formed at the other side end. Enclose it in the shape of this letter.

The horizontal panel 15 is formed to be integrally extended from the lower end of one vertical panel 12a among two vertical panels 12a and 12b.

The wall panel 16 is arranged in close contact with the wall side through two layers of vertical panels 12a and 12b, and is arranged in close contact with the floor side through the horizontal panel 15 which is bent 90 ° from the vertical panels 12a and 12b. It is installed at the corner where the wall and the floor are in contact.

In particular, the wall panel 16 is provided with an air passage 10 for the flow of air can effectively remove the moisture on the upper slab.

In this case, the vertical panels 12a and 12b are manufactured in the form of a square panel in which a plurality of cups 11a protruding inward are formed, and are formed in a symmetrical structure that is in contact with each other based on the first bent portion 13. .

In this case, the first bent portion 13 means that the cut out in advance so that it can be easily folded. When the vertical panels 12a and 12b are folded based on the first bent portion 13, the first bent portion 13 is doubled. At this time, the plurality of cups (11a) formed on each fold is in contact with each other to form an air passage (10) which communicates in the vertical direction inside the vertical panels (12a, 12b) by spaced apart from each other.

At this time, by minimizing the separation distance between the two vertical panels (12a, 12b) on the basis of the first bent portion 13, it is possible to reduce the material.

Preferably, the first bent portion 18 and the second bent portion 23 may be formed to be able to be bent a pair of parallel lines, the interval of the parallel lines may be formed 1 to 1.5 times the height of the protrusion of the cup (11a). .

The cup 11a plays a role of forming air passages 10 for water discharge and ventilation while acting as a resistance to side pressure due to the pouring of lightweight foam concrete or plastered concrete.

As a result, the two pairs of vertical panels 12a and 12b can effectively maintain the side-by-side separation state by the firm brace between the cups 11a which are in contact with each other. It can be done effectively.

Here, the cups 11a and the cups 11b and 11c to be described later may be formed in a tapered cup shape in which the diameter of the cup 11a and 11c gradually decreases toward the inside thereof.

However, the cup may be formed in the form of a polygon such as a triangle, a square, etc. in addition to the circular shape.

In addition, the cup 11a formed on the vertical panels 12a and 12b of the wall panel 16 and the cup 11b formed on the horizontal panel 15 and the floor panel 17 to be described later are formed. The cup 11c may be arranged in various forms such as a regular arrangement or an irregular arrangement over the entire panel area.

In addition, a second bent portion 23 for fastening between the panels may be provided at one end of the vertical panels 12a and 12b that maintain the nested state while forming the air passage 10 therein.

At this time, when the second bent portion 23 is bent to complete a shape, the shape of the letter “c” is formed, and the end portion of the vertical panel opposite to the “c” groove is accommodated to prevent the gap.

Accordingly, when the vertical panels 12a and 12b are folded to each other and then wrapped with the second bent portion 23, the folded state of the vertical panels 12a and 12b may be maintained, and the cup 11a may be inside. By contacting each other is able to form the air passage (10).

In addition, the vertical regions 12a and 12b of the wall panel 16 may be provided with a cutting region 20 in which the cup 11a is not formed at an intermediate position of the panel.

In this case, a plurality of cutting reference protrusions 21 may be formed on the vertical panel of the cutting region 20, that is, the vertical panel 12b attached to the wall, to protrude inwardly with the air passage 10 formed therein.

Accordingly, after the cement mortar such as the sound insulating material and the foamed concrete is constructed, the cutting criteria for cutting the vertical panels 12a and 12b can be set, and the cutting operation can be made easier.

For example, when the vertical panel is cut after completion of the construction, if cement mortar is filled in the cup as in the past, the cutting is interrupted, so cutting the upper part after applying the cement mortar to the area without the cup, It can be easily performed.

In particular, the wall panel 16 is characterized in that the horizontal panel 15 is formed integrally formed to extend to the bottom of the portion where the wall and the floor.

The horizontal panel 15 is formed to extend integrally so as to be bent from a lower end of any one vertical panel, that is, the vertical panel 12a disposed forward and out of the two vertical panels 12a and 12b disposed forward and backward. .

That is, the horizontal panel 15 can be freely bent with respect to the vertical panel 12a, and when installed, the horizontal panel 15 can form an angle of 90 ° with the vertical panel 12a.

Accordingly, since the horizontal panel 15 and the vertical panels 12a and 12b of the wall panel 16 are closely arranged at the same time as the wall and the bottom contacted with each other, the operation of attaching them separately as in the past can be omitted. It is possible to secure the excellent construction properties and construction quality for the connection part.

Like the vertical walls 12a and 12b, a plurality of cups 11b are formed in the horizontal panel 15. At this time, the cups 11b protrude toward the bottom contacting the floor to maintain a gap between the floors. Accordingly, a passage through which air can flow between the panel and the floor can be secured, and the passage thus secured is in communication with the air passage 10 formed inside the vertical walls 12a and 12b, Moisture on the bottom side of the slab can be easily discharged to the outside through the air passage (10).

Referring to FIG. 4, there is shown a wall panel 16 that is formed of a single piece of two vertically spread panels 12a, 12b and one horizontal panel 15. The folding process of the wall panel 16 as described above is as follows.

First, the vertical panels 12a and 12b extending to both sides are placed upright to form 90 ° with respect to the horizontal panel 15, and then one vertical panel 12b is horizontally centered on the first bent portion 18. Fold in the direction, that is, turn to the side, close to the back of the other vertical panel (12a) is folded.

Subsequently, the second bent portion 23 of the vertical panels 12a and 12b overlapped with each other is bent to form an “c” shaped end portion so that the two layers of vertical panels 12a and 12b are fixed.

At this time, the air passage 10 is formed between the two-ply vertical panels 12a and 12b.

The floor panel 17 is connected to the horizontal panel 15.

5 is a perspective view showing a floor panel of the moisture removing ventilation panel according to an embodiment of the present invention.

Referring to FIG. 5, the floor panel 17 is a panel installed on the slab bottom, and is installed in a structure connected to the horizontal panel 15 of the wall panel 16.

The floor panel 17 is installed at a predetermined distance from the floor by using the cup 11c in contact with the floor, thereby allowing the moisture and moisture of the slab floor to be discharged to the outside through the space with the floor side.

To this end, the floor panel 17 is provided with a plurality of cups 11c protruding toward the bottom contacting the floor and being placed on the floor to maintain a gap between the floor and the plurality of cups 11c formed at both ends of the panel. ) And the cups 11b formed at the ends of the horizontal panel 15 may overlap each other so as to overlap each other.

Accordingly, a plurality of floor panels 17 may be extended and used depending on the installation location. For example, as shown in FIG. 6, the floor panels 17 and the wall panels 16 are lined up. By arranging them side by side, the mutual ends can be connected by fitting the cups 11b and 11c.

In addition, the cup (11c) in the floor panel 17 serves to block the impact sound in addition to the space composition, for example, since the noise generated from the top inside the cup is extinguished by rotation, light impact sound and heavy impact sound It can effectively block.

At this time, the present invention can be constructed by wrapping the wall panel 16 and the floor panel 17 with a nonwoven fabric 13 as shown in FIG.

FIG. 7 is a perspective view illustrating an example in which a nonwoven fabric is wrapped around a wall panel and a floor panel in a moisture removing ventilation panel according to an embodiment of the present invention, and the wall panel 16 and the floor as shown in FIG. 7. When the construction of the panel 17 is wrapped around the nonwoven fabric 13, during construction of the reinforced concrete structure, due to the wet process that proceeds from the upper surface of the slab, moisture that accumulates in the center of the slab and moisture generated in the slab concrete curing process It can be absorbed by nonwoven fabric and spread evenly throughout the base panel to be quickly evaporated and discharged to the outside, thereby reducing the drying time compared to the natural drying method, and it is economical by shortening the construction period. It prevents odors and molds by preventing corrosion, and prevents cracking and peeling of slab concrete. It has the effect of increasing the water stability.

In addition, the present invention is to cover the outer surface of the wall panel and the floor panel with a non-woven fabric, thereby preventing moisture, concrete and mortar flow into the cup to block the air passage, thereby improving the drying efficiency. .
