As a result, a smooth floor face with a specified inclination is formed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for constructing a self-leveling material, and in particular,
The present invention relates to a method for applying a self-leveling material that allows a floor surface having a predetermined water gradient to be easily constructed by simply flowing the self-leveling material when forming a floor surface using the self-leveling material.

[Prior Art] Due to the design of the floors of balconies, bathrooms, parking lots, rooftops, etc. of buildings, it is necessary to provide a water gradient for drainage. Conventionally, in order to form a floor surface with a water slope, it is necessary to trowel the surface to be poured at the time of pouring the base concrete to form a floor surface with a predetermined water slope. The method used is to apply a rough finish and then use finishing mortar to form a floor surface with a predetermined water slope.

On the other hand, in recent years, self-leveling materials have been developed that can form a smooth surface by natural flow simply by pouring a highly fluid kneaded material onto a concrete pouring surface, and are being widely used. Self-leveling materials are very advantageous because they do not require complicated trowel finishing or skilled plasterers, and can form a smooth floor surface simply by pouring the self-leveling material and leveling it with a dragonfly.

[The invention attempts to solve i! ! l! i] The conventional method of troweling concrete at the time of pouring or using cement mortar after hardening requires a skilled plasterer to carry out the troweling, and also requires a level accuracy of the finished floor surface. The problem is that it is bad.

On the other hand, self-leveling materials are intended to form a smooth floor surface just by pouring them.
Although this is an effective method for forming a horizontal floor surface, it cannot be applied when forming a floor surface that requires a water gradient.

The present invention aims to solve the above-mentioned conventional problems and provide a self-leveling material construction method that can easily and efficiently construct a floor surface with a water gradient using the self-leveling material. .

[Means for solving CIUA] The self-leveling material construction method of the present invention is a method of forming a floor surface with a water slope using the self-leveling material, in which a smooth plate is sloped along the underlying concrete surface. A self-leveling material is poured between the base concrete and the chain plate to form a floor surface with a predetermined water gradient.

[Operation] According to the self-leveling material construction method of the present invention, a smooth board (hereinafter sometimes referred to as "upper formwork") is placed on the base concrete along the water gradient required for the floor finish surface. A self-leveling material is poured between the base concrete and the upper formwork. As a result, the self-leveling material flows and hardens following the smooth plate surface of the upper formwork placed on the base concrete, so that the floor surface with a water slope installed with the upper formwork can be easily cleaned. Formed efficiently and accurately.

In addition, in the present invention, it is desirable that the upper formwork used not only have a smooth surface but also be made of a material with good mold releasability so that it can be easily removed after the self-leveling material is applied. . Specifically, plywood or synthetic resin molds coated with a synthetic resin such as styrene resin or epoxy resin are suitable for producing a beautiful finished surface because the surface is smooth and peelable.

Furthermore, as the self-leveling material used in the present invention, all commercially available self-leveling materials such as gypsum-based and cement-based materials can be used. Since water flows through the floor surface, it is preferable to use a cement-based self-leveling material with good water resistance. In particular, it is advantageous to use a cement-based material with a flow value of 210 mm or more and high fluidity because it takes less time to fill the gap between the base concrete and the upper formwork and allows a smooth surface to be easily formed. be.

[Examples] Examples of the present invention will be described in more detail below with reference to the drawings.

FIG. 1 is a plan view showing one embodiment of the self-leveling material application method of the present invention. Figure J2 is II-II in Figure 1.
It is a sectional view along a line.

The method of this embodiment is a method of forming a floor surface with a water slope on a base concrete 2 in contact with a wall 1 using a self-leveling material. The base concrete 2 has a slight slope, and the surface is not smooth but uneven. That is, in the method of the present invention, since a smooth floor surface having a desired water gradient can be formed using the self-leveling material, the base concrete 2 does not necessarily have to have a gradient equivalent to the desired water gradient. Moreover, the surface does not need to be a smooth surface, and may be an uneven surface.

In this embodiment, first, the upper formwork 3 is installed on the base concrete 2 at a portion where the intended floor surface is to be formed, at a distance from the base concrete 2.

In this case, the height adjustment of the upper formwork 3 is performed using the base concrete 2.
This is done by using a plurality of hits (four in the figure) or spacers 4 provided at appropriate locations on the top. In normal cases, the distance between the upper formwork 3 and the base concrete 2 (d in Figure 2) is 5.
~50 mm, especially about 10 to 20 mm.

In addition, a weir 5 is provided at the edge of the upper formwork 3 other than the contact side with the wall 1.
A, 5B, 5C are installed, base concrete 2 and upper formwork 3
Prevent self-leveling material from flowing out between the These weirs 5A, 5B, and 5C are fixed to the upper formwork 3 with screws 6.

In this embodiment, the upper formwork 3 has an inlet 3A for self-leveling material. This input port 3A is located at a location on the upstream side of the water gradient when the upper formwork 3 is placed in the construction area.
It is formed to protrude from the plate surface 3B of the upper form body.

After arranging the upper formwork 3 in this manner, the self-leveling material is charged and filled from the input port 3A.

By adding the self-leveling material, the gap between the upper formwork 3 and the base concrete 2! When 7 is sufficiently filled with the self-leveling material, the surface of the self-leveling material in the input port 3A will no longer settle. Therefore, the self-leveling material is applied until the surface of the self-leveling material within this inlet 3A no longer settles.

After the self-leveling material is charged and filled, it is allowed to harden as it is, and after hardening, the upper formwork 3 and weirs 5A to 5C are removed. As a result, a floor surface with a smooth surface that follows the smooth surface of the upper formwork 3 is formed with a water gradient that follows the slope of the upper formwork 3.

Specific examples will be described below.

Example 1 A parking lot with a width of 3 m and a length of 6 m with a slope of 20 was constructed using the method shown in FIGS. 1 and 2. First, base concrete 2 with the same slope is poured in advance, and base concrete 2 is poured.
After curing, as shown in FIG. 341 and FIG. 2, the upper formwork 3 was installed, and the self-leveling material was poured from the input port 3A of the upper formwork 3. As the self-leveling material, a material having a water/material ratio of 26% and a flow value of 210 mm was used. The self-leveling material was heated and cured until the surface height of the self-leveling material in the input port 3A did not decrease, and after curing, the upper formwork 3 and weirs 5A to 5C were removed. As a result, it was confirmed that a floor surface with a smooth surface and a desired water gradient was formed.

[Effects of the Invention] As detailed above, according to the method of the present invention, a self-leveling material can be used to easily and efficiently perform high-quality plastering without requiring complicated trowel finishing or skilled plasterers. A smooth floor surface with a water gradient can be formed with precision.
