Description

Semi-dry floor structure of balcony of apartment house and construction method thereof}

The present invention relates to apartment balconies, and more specifically, to an apartment balcony floor structure that allows easy and simple construction and defect repair of apartment balcony floors, and a semi-dry construction method using the same.

Generally, the construction of a new apartment building involves the construction of a balcony.

Since water is usually used for cleaning balconies, appropriate drainage and waterproofing treatment must be carried out during floor construction.

As shown in Figure 1, the balcony floor construction of a typical apartment complex involves pouring waterproof mortar (20) on the concrete floor concrete layer (10), and then, when curing of the waterproof mortar (20) is completed, lightweight foam concrete (30). After pouring, when the curing of the lightweight foam concrete (30) is completed, cement mortar (40) is poured and then porcelain tiles (50) are attached.

The balcony of a typical apartment building with this structure is widely used because it is the cheapest and has excellent homogeneity with concrete structures by using cement.

However, the balcony of a typical apartment complex as described above not only requires a long construction period due to wet construction, but also has poor workability, such as large equipment having to enter the workplace to pour lightweight foam concrete (30), and construction and labor costs. There are limitations in that the expenditure is large and construction is difficult during the winter.

In addition, in the case of a defect in the balcony of a typical apartment building, it is difficult to find a leaking area, and when repairing, all existing waterproofing mortar (20), lightweight foam concrete (30), cement mortar (40), and tile (50) must be removed before full waterproofing. Because construction must be carried out, a large amount of waste is generated, and environmental problems arise when waste is disposed of.

Domestic Registered Utility Model Publication No. 20-0371845

The present invention was devised to solve the above-mentioned problems, and provides a semi-dry floor structure and construction method for apartment balconies that prevent excessive construction time, costs, and waste generation due to wet construction, and allow easy detection of water leaks when defects occur. The purpose is to provide.

In order to achieve the above object, the semi-dry floor structure of the apartment balcony according to the present invention includes a coating waterproof layer formed on the upper part of the concrete floor concrete layer forming the floor of the apartment balcony, and EPS insulation plates arranged on the upper part of the coating waterproof layer. It includes an insulation layer, urethane foam tightly fitted between the joints of the EPS insulation plates and the wall, a cement mortar layer formed on top of the insulation layer, and a tile layer formed on the cement mortar layer.

In addition, the semi-dry floor construction method of the apartment balcony according to the present invention includes the steps of preparing the surface of the concrete floor concrete layer forming the floor of the balcony of the apartment building, and applying waterproofing paint to the surface of the prepared concrete floor concrete layer to create a waterproof coating layer. forming a heat insulating layer by arranging EPS insulating plates on the surface of the waterproofing layer, tightly packing urethane foam between the arranged EPS insulating plates, and forming a cement mortar layer on the top of the EPS insulating plates. It includes the step of forming a tile layer on top of the cement mortar layer.

In this case, the step of cleaning the surface of the floor concrete layer includes removing dirt, dust, etc. from the surface of the floor concrete layer, and then removing bending, steps, lifts, laitances, weak points, and significant protrusions on the surface of the floor concrete layer. This can be done by flattening it so that it does not exist.

In addition, after the step of tightly fitting the urethane foam between the arranged EPS insulation plates, a further step of forming a wire mesh layer may be performed.

The present invention, constructed as described above, unlike the conventional method using lightweight foam concrete, uses EPS insulation board to construct the floor of the balcony of an apartment complex, so it suffers from poor workability due to the use of lightweight foam concrete, excessive expenditure on construction and labor costs, and winter weather. It has the effect of solving various problems at once, such as limitations in construction.

In addition, the present invention has excellent workability because the EPS insulation board can be easily removed by removing only the cement mortar layer, unlike the conventional method in which waterproof mortar, lightweight foam concrete, and cement mortar must all be removed when a defect occurs after construction. This is significantly reduced, making it environmentally friendly, and it is expected that water leaks can be easily found and repair work can be easily performed.

Figure 2 is a cross-sectional view showing a semi-dry floor structure of an apartment balcony according to an embodiment of the present invention, and Figure 3 is a perspective view of an EPS insulation board constituting the present invention. As shown, a semi-dry floor structure of an apartment balcony according to the present invention is shown. The floor structure includes a waterproofing layer (100), an insulation layer (200), a urethane foam (300), a cement mortar layer (400), and a tile layer (500).

The coating waterproof layer 100 is formed on the upper part of the concrete floor concrete layer (A) that forms the floor of the balcony of an apartment building to maximize the waterproofing effect, and a waterproof paint made of synthetic resin material is applied to the upper part of the concrete floor concrete layer (A). It can be formed by doing so.

The insulation layer 200 is composed of a plurality of EPS insulation plates 210 arranged on the dried waterproof coating layer 100.

In this case, the EPS insulation plate 210 is preferably made of EPS (Expanded Poly Styrol) material, which has excellent insulation, constructability, and sound insulation properties.

The EPS material in this example is a thermoplastic plastic that is light and has no taste or smell, so it is widely used as a case and packaging material for household goods, toys, electrical insulators, and electronic products. It is ultra-light, environmentally friendly, and water-resistant through foaming and molding. , one or two types of bead method insulation plates that maximize compression resistance, independence, and economic efficiency can be applied (according to the insulation material grading of the Ministry of Land, Infrastructure and Transport's "Energy Saving Design Standards for Buildings").

This EPS insulation board 210 can be cut as desired with a knife, saw, heat conduction, etc., and is easy to attach and fix with adhesive or nails, so it has excellent constructability and processability. Due to its structural characteristics of being formed of independent closed cells, it can not only allow moisture to pass through, but also has excellent workability and processability. Even if placed in water for a long time, the amount absorbed is extremely small and there is very little risk of deterioration.

The urethane foam 300 is tightly fitted between the joints of the EPS insulation plates 210 and the wall to prevent the flow of the EPS insulation plates 210 and at the same time prevent cement mortar from flowing between the EPS insulation plates 210.

The cement mortar layer 400 is made of cement mortar poured on top of the insulation layer 200.

The tile layer 500 is made of regular floor tiles made of porcelain material and is constructed by attaching them one by one to the top of the cement mortar layer 400 using adhesive mortar or dry-curing adhesive.

Figure 4 is a cross-sectional view showing a semi-dry floor structure of an apartment balcony according to another embodiment of the present invention. As shown, a wire mesh layer 350 may be formed on the top of the EPS insulation plate 210.

In this case, the wire mesh layer is integrated with the cement mortar poured on top of the EPS insulation plate 210 and improves the adhesive strength of the cement mortar.

The semi-dry floor of the apartment balcony of the present invention constructed as described above is constructed in the following manner.

Figure 5 is a flowchart showing a semi-dry floor construction method for an apartment balcony according to the present invention, and Figure 6 is a cross-sectional view sequentially showing the semi-dry floor construction method for an apartment balcony according to the present invention. First, the concrete floor concrete layer Clean up the surface of (A). (S1)

As a process of flattening the surface of the concrete floor concrete layer (A), after removing dirt and dust from the surface of the concrete floor concrete layer (A), bending, steps, lifting, laitance, This can be easily done by flattening the surface so that there are no weak points or significant protrusions.

However, it is advisable to provide a gradient of 0.1% or more toward the sump so as not to interfere with drainage.

When the surface of the concrete floor concrete layer (A) is prepared, a waterproof paint made of epoxy is applied to the surface of the prepared concrete floor concrete layer (A) using a roller or spray to form the waterproof film layer (100). (S2) )

When the waterproof paint is completely dried, EPS insulation plates 210 are arranged on top of the waterproof coating layer (S3).

In order to increase work efficiency, workers transport EPS insulation plates 210 in small quantities and arrange them at regular intervals on the surface of the floor concrete layer (A), and then place the distributedly arranged EPS insulation plates 210 around the perimeter. It is desirable to construct in an expanded arrangement.

The EPS insulation plate 210 is made of EPS material and has excellent insulation properties, so it can prevent condensation on the balcony floor.

When the arrangement of the EPS insulation plates 210 is completed, the urethane foam 300 is tightly sealed between the joints of the arranged EPS insulation plates 210 and the wall to waterproof the EPS insulation plates 210 with the cement mortar to be installed later. Prevent leakage from joints and between walls. (S4)

Meanwhile, when the urethane foam 300 is completed, the wire mesh layer 350 may be formed by laying a previously prepared wire mesh layer 350 on top of the bound EPS insulation board 210.

Then, after forming the wire mesh layer 350, cement mortar is poured on top of the wire mesh layer 350 to form a cement mortar layer 400 with a thickness of about 10 to 15 mm. ( S5)

At this time, the cement mortar is made by mixing cement and sand in a weight ratio of 1:3 and then diluting it with water. It is desirable to use it within 2 hours.

Meanwhile, the wire mesh layer 350 made of cement mortar and dissimilar materials improves the adhesive strength of the cement mortar layer 400.

When curing of the cement mortar is completed, porcelain floor tiles are attached to the top of the cement mortar layer 400 to form the tile layer 500 (S6).

At this time, the thickness of the floor tile is approximately 8mm. After applying adhesive mortar or dry-curing adhesive to the upper part of the cement mortar layer (400), attach the floor tile and use a bar to press the floor tile to ensure verticality and horizontality with precision. It is constructed in a tailored manner.

When using adhesive mortar, the area for one application of floor tiles is preferably 1.2 m2 or less, considering the curing speed and workability of the adhesive mortar, and the attachment time is preferably within 15 minutes after mixing the adhesive mortar.

When using a dry-curing adhesive, limit the area applied once to within 3㎡ and be careful not to exceed the designated use time.

After going through this process, the construction of the balcony floor is completed.

In the present invention, the balcony floor is constructed using EPS insulation board 210 instead of lightweight foam concrete, so there is no need to enter large equipment into the workplace to pour lightweight foam concrete, and the resulting construction and labor costs are not required. Construction can be performed without difficulty even in the winter.

In addition, in case of defects after construction, the EPS insulation board (210) can be easily removed by simply removing the tile layer (500) and cement mortar layer (400), so workability is excellent, and the amount of waste disposal is significantly reduced, making it environmentally friendly and preventing water leaks. can be easily found, allowing repair work to be easily performed.

As such, although the preferred embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above-described embodiments, and modifications may be made by those skilled in the art without departing from the spirit of the present invention. It is possible, and such modifications will fall within the scope of the present invention.
