Description

Structure for reducing noise between floors and method of construction of building of flooring system using the same}

The present invention relates to an inter-floor noise prevention structure and a dry heated floor construction method using the same.

Recently, with rapid industrial development and economic growth, demand for buildings has increased, and along with this, land prices have continued to rise. As a result, in the case of office buildings constructed in urban areas with high land prices, there is a trend towards high-rise buildings as a way to use land efficiently. In particular, as population concentration in large cities has intensified in recent years, the type of residential buildings is becoming more concentrated in multi-story apartments such as apartments, villas, and multi-family houses to solve the housing problem in big cities.

However, in the case of these multi-story buildings, the floor of the upper floor and the ceiling of the lower floor are shared between the upper and lower floor households as the same structure called an inter-floor slab, so various noises generated in the upper floor are transmitted to the lower floor through this inter-floor slab, thereby disturbing other people. There is a problem that interferes with your life or work. In addition, recently, disputes and civil complaints due to noise between floors in apartment complexes have been rapidly increasing.

Meanwhile, the underfloor heating system (heating system) of a building is largely divided into wet and dry. The heating system applied to residential buildings such as single-family houses, villas, and apartments is a wet method, in which hot water pipes are buried in the concrete floor and heating fluid is supplied. A structure that supplies heat to the floor has been commonly used.

This wet method is a conventional floor heating method, and has the problem of having a high load, high energy consumption, being affected by the climate, making construction impossible in the winter, and requiring a curing period of more than a week. In particular, in terms of piping management after construction, repair and replacement are not easy, so repairing defects requires considerable cost and time, and there are limitations in applying variable designs. Accordingly, there is a recent trend of replacing it with a dry heating system.

A typical dry heating system consists of a piping panel that installs heat radiation pipes such as hot water pipes and electric heating pipes, and an underfloor heating plate that is prefabricated on the upper surface of this piping panel, and is used to create an ondol using a dry method without using cement mortar. It is constructed after finishing, and has advantages over wet ondol, such as ease of construction, shortened construction time, and ease of repair.

However, in the conventional dry heating system, a shielding layer is formed in contact with the concrete slab layer, so there is a problem in that the shielding performance of shock and noise transmitted from the top is significantly reduced.

Figure 1 is a cross-sectional view of an interfloor noise prevention structure according to an embodiment of the present invention.

As shown in Figure 1, the inter-floor noise prevention structure 1 according to an embodiment of the present invention includes a concrete slab layer 100 and a first fiber board layer formed on the concrete slab layer 100 ( 200), an intermediate layer 300 formed on the first fiber board layer 200, a second fiber board layer 400 formed on the middle layer 300, and a second fiber board layer 400 It includes a fiber panel layer 500 formed on the top of.

Here, the concrete slab layer 100 divides the upper and lower floors of a multi-story building and is formed by laying floor concrete.

Figure 2 is a perspective view of a fiber board layer according to an embodiment of the present invention, in which a first fiber board layer 200 is formed on the top of the concrete slab layer 100.

As an example, the first fiber board layer 200 may be formed by stacking and needle-punching a plurality of sheet-shaped nonwoven webs 210 in multiple layers, as shown in Figure 2. In this case, the first fiber board layer (200) The fiber density is preferably 300 to 500 kg/㎥. If the fiber density of the first fiber board layer 200 is less than 300 kg/㎥, the noise shielding effect cannot be obtained, and if the fiber density exceeds 500 kg/㎥, there is a problem of reduced constructability and economic feasibility due to increased weight.

In addition, it is preferable that the fiber density of the first fiber board layer 200 is lower than that of the fiber panel layer 500, which will be described later, because the higher the fiber density, the better the noise can be transmitted to the lower part. This is to minimize noise transmitted to the lower layer by using the first fiber board layer 200, which has a relatively low fiber density.

Figure 3 is a plan view of the middle layer according to an embodiment of the present invention.

Referring to FIG. 1, an intermediate layer 300 is formed on top of the first fiber board layer 200. As shown in FIG. 3, the intermediate layer 300 includes a plurality of rectangular members 310 arranged side by side at a predetermined interval in the width direction and a plurality of spacers 320 interposed between a pair of adjacent rectangular members 310. It includes, and the plurality of spacers 320 may be arranged to be spaced apart from each other at predetermined intervals along the longitudinal direction of the angle member 310. Accordingly, an air layer 330 is formed between a pair of adjacent angle members 310, and this air layer 330 serves to absorb or block noise.

Here, the spacer 320 does not need to be used, but if the spacer 320 is located between the angle members 310, problems such as the angle member 310 being tilted to one side can be prevented, and over time, the spacer 320 may not be used. It is possible to prevent irregular deformation of the second fiber board layer 400 and the fiber panel layer 500 that may occur. In other words, it is possible to prevent atypical deformation, such as deformation caused by the center of a room mainly used by people sinking down more quickly.

The middle layer 300 serves to reinforce the rigidity of the interlayer noise prevention structure 1 by supporting the second fiber board layer 400, the fiber panel layer 500, and the finishing layer 800, which will be described later. For example, the angle member 310 may be made of a metal material such as stainless steel or aluminum, and may be made of a hollow pipe with a rectangular cross-sectional shape.

Meanwhile, a second fiber board layer 400 is formed on the middle layer 300. The second fiber board layer 400 may be made of the same material as the first fiber board layer 200 described above with reference to FIG. 2, and, like the first fiber board layer 200, is made of a plurality of sheet-shaped nonwoven webs ( The fiber density of the second fiber board layer 400 on which 410) is laminated is preferably 300 to 500 kg/㎥.

At this time, it is preferable that the fiber density of the second fiber board layer 400 is lower than the fiber density of the fiber panel layer 500, which will be described later, because the higher the fiber density, the better the noise can be transmitted to the lower part. This is to minimize noise transmitted to the lower layer by using the second fiber board layer 400, which has a relatively low fiber density.

If the fiber density of the fiber panel layer 500 is less than 800 kg/㎥, the noise absorption or blocking effect is minimal, and if it exceeds 1000 kg/㎥, there is a problem of reduced constructability and economic feasibility due to increased weight.

Hot water piping is installed in a zigzag shape on the floor of each floor of the building. For this purpose, the first hot water piping groove 610 of the lower panel 600 and the second hot water piping groove 710 of the upper panel 700 are also installed in a zigzag shape. is formed
