However, this conventional technology had the problem that it was not an eco-friendly material because it used waste rubber.

In addition, the conventional technology uses waste rubber with an irregular shape, so when mixed with concrete, the waste rubber is not evenly and evenly distributed within the concrete, but is positioned biased to one side, significantly reducing the effectiveness of inter-floor noise blocking and insulation. There was a problem with this.

FIG. 1 shows a photograph of fragments of waste rubber used in conventional technology and a portion of lightweight concrete using the same.

As shown in Figure 1, the shape of the waste rubber itself is not constant, and when looking at lightweight foam concrete containing the waste rubber, the waste rubber is not evenly distributed in the concrete, but there are places where a lot of the waste rubber is located. There were some places where there were too few of them, so there was a problem that the effectiveness of noise blocking and insulation between floors was low.

The present invention was proposed to solve the problems described above, and when manufacturing mixed foam concrete containing expandable polystyrene granules (EPS), the expandable polystyrene granules can be evenly distributed within the mixed foam concrete, and can be used for pouring and pouring.

The photos showing each are shown.

As shown in the drawing, the EPS granule mixed foam concrete manufacturing apparatus 100, which includes expandable polystyrene granules and is excellent for reducing interfloor noise according to an embodiment of the present invention, includes a cement transfer pipe 10 and an EPS transfer pipe. It includes a pipe 20, a mixing tank 30, a water transfer pipe 50, a stirrer 60, a discharge pipe 70, and a foaming agent injection port 70.

The cement transfer pipe 10 has a cement transfer screw 12 inside, through which cement is transferred.

The EPS transfer pipe 20 has a grain transfer screw 22 inside, and expandable polystyrene (EPS) particles are transferred thereto.

The mixing tank 30 is a container that accommodates cement and expandable polystyrene granules transferred from the cement transfer pipe 10 and the EPS transfer pipe 20.

The admixture transfer pipe 40 communicates with the mixing tank 30 and transports the cement admixture to the mixing tank.

The water transfer pipe 50 communicates with the mixing tank 30 and transports water to the mixing tank 30.

The stirrer 60 is located inside the mixing tank 30 and evenly mixes the contents contained within the mixing tank 30.

The discharge pipe 70 communicates with the mixing tank 30 and transports the mixture mixed in the mixing tank 30.

The foaming agent injection port 70 is located between the mixing tank 30 and the discharge pipe 70, communicates with the discharge pipe 70, and is used to spray the foaming agent to form bubbles inside the concrete.

Meanwhile, it is preferable to spray 0.4 to 0.8 liters of the foaming agent per 1 m3 of the mixture volume mixed in the mixing tank 30 to form bubbles in the mixed concrete.

In this embodiment, the foaming agent is a vegetable foaming agent, which is purchased commercially, so a detailed description is omitted.

Meanwhile, in this embodiment, the admixture is characterized by containing 30 to 40% of acryl copolymer, 10 to 20% of inorganic compound, and 30 to 40% of water per weight.

If these ingredients are present, cement and the EPS granules can be mixed well.

In addition, in the cement transfer step and the pole transfer step, the transfer speed of cement and pole is 2 minutes 20 seconds to 3 minutes per 1 ㎥ volume of the mixing tank, and the diameter of the cement transfer pipe for transporting cement and the grains for transporting EPS grains are It is desirable to have different diameters of the pipes.

In this way, by varying the diameter of the cement transfer pipe and the diameter of the EPS granule transfer pipe, it is possible to control the amount of materials with different specific gravity injected into the mixing tank so that the EPS particles can be evenly distributed throughout the concrete.

More preferably, the diameter of the cement transfer pipe is 5 inches, and the diameter of the granule transfer pipe is 7 inches.

This is because the best results can be obtained with this diameter.

A detailed description will be given of the method of manufacturing EPS granule-mixed foam concrete using the EPS granule-mixed foamed concrete manufacturing device, which includes expandable polystyrene granules according to the present embodiment having the above-described configuration and is excellent for reducing inter-floor noise.

First, as shown in FIG. 2, 6 to 12 bags per cubic meter of the mixing tank are transferred to the mixing tank 30 where the stirrer 60 is located through the cement transfer pipe 10. I order it.

More preferably, 8 to 10 bags of cement are transferred.

If the amount of cement is too large, the viscosity of the EPS granule mixed foam concrete is high, making transportation difficult, and if the amount of cement is too small, the viscosity of the EPS granule mixed foam concrete is low, making it too diluted and unsuitable.

Therefore, cement has an appropriate viscosity when 6 to 12 bags are used, and 8 to 10 bags of cement are appropriate to produce better quality EPS granule mixed foam concrete.

This is a figure calculated through countless trials and errors.

At the same time, 600 to 1000 liters of the EPS grains are transferred to the mixing tank 30 where the stirrer 60 is located through the EPS grain transfer pipe 20.

More preferably, 800 to 850 liters of the EPS granules are transported.

This is because if the amount of the EPS grains is too small, the amount of cement becomes too much, and if the amount of the grains is too large, the amount of cement becomes too small and is not suitable.

The appropriate amount of EPS granules is also a figure calculated through much trial and error.

The cement and EPS grains are evenly mixed by the stirrer 60 included in the mixing tank 30.

In this example, the diameter of the cement transfer pipe was 5 inches, and the diameter of the granule transfer pipe was 7 inches.

In addition, the transfer speed of the grains in the cement and EP was set at 2 minutes 20 seconds to 3 minutes per 1 ㎥ volume of the mixing tank.

In this way, by varying the diameter of the cement transfer pipe (10) for transferring cement and the diameter of the EPS granule transfer pipe (20) for transferring EPS grains, the amount of materials with different specific gravity input into the mixing tank is adjusted to control the amount of material in the concrete. It is possible to ensure that the EPS particles are evenly distributed throughout.

Subsequently, 1.2 liters to 2.0 liters of the admixture per 1 cubic meter of the mixing tank is transferred through the admixture transfer pipe 40.

It is well known that the admixture serves to ensure that cement and EPS grains are well mixed with each other, and that it can play various other roles.

At the same time, 250 to 350 liters of water per 1 ㎥ volume of the mixing tank is transferred to the mixing tank (30) through the water transfer pipe (50).

In this way, the cement, EPS grains, admixture, and water transferred to the mixing tank are stirred and mixed well.

Next, the contents contained in the mixing tank 30 are transferred toward the discharge port through the discharge pipe 70. At this time, various configurations that can generate pressure can be used.

In addition, 0.4 to 0.8 liters of foaming agent is sprayed through the foaming agent spray pipe 80 branched between the mixing tank 30 and the discharge pipe 70 to form bubbles in the EPS granular mixed foam concrete.

The bubbles have a very small diameter compared to the EPS particles, and play a significant role in reducing interfloor noise.

Since the foaming agent is common, detailed description will be omitted.

The EPS granule mixed foam concrete prepared in this way is shown in Figure 5.

As shown in FIG. 4, the EPS grains are evenly mixed with cement to obtain EPS grain mixed foam concrete in which the EPS grains are evenly distributed throughout.

If the EPS granule mixed foam concrete obtained in this way is poured and cured on the upper part of the lower slab as shown in Figure 5, it can demonstrate an excellent effect on inter-floor noise.
