That is, when pouring the lightweight foam concrete (140), moisture can be prevented from penetrating into the interlayer member (110) through the waterproof vinyl sheet (130).

In addition, the sound absorption effect can be increased by dispersing and canceling out noise transmitted to the concrete slab (10) and wall surface (20) through the lightweight foam concrete (140), interlayer member (110), and side member (30).

In addition, an air layer (121) can be formed between the supporting members (120) by the waterproof vinyl sheet (130) fixed to the supporting member (120), and the sound absorption effect can be further enhanced by the air layer (121).

Here, considering the load of the lightweight foam concrete (140), the waterproof vinyl sheet (130) is spread over the upper portion of the support member (120) and sags between the support members (120) to form a hemispherical shape, but can be spaced apart from the upper surface of the interlayer member (110) by a certain distance.

That is, the air layer (121) can be formed between the hemispherical waterproof vinyl sheet (130), the support member (120), and the interlayer member (110).

The above inter-floor noise reduction structure (100, 100') may have a groove (122) formed on the side of the support member (120) along the longitudinal direction of the support member (120), and air may remain inside the groove (122) to implement an air pocket effect, thereby further enhancing the sound absorption effect.

Here, the groove (122) may be formed on both sides of the support member (120) as shown in FIG. 2, or may be additionally formed on the lower surface of the support member (120) as shown in FIG. 4.

The above waterproof vinyl sheet (130) may be formed of a known synthetic resin material such as polyester, but is not limited thereto and any waterproof material may be used.

FIG. 5 is a schematic cross-sectional view of an interlayer noise reduction structure according to a third embodiment of the present invention, FIGS. 6 and 7 are perspective views and plan views, respectively, of a support member and a support frame illustrated in FIG. 5, and FIGS. 8 and 9 are perspective views and plan views, respectively, showing a state in which a sound-absorbing plate is mounted on the support frame illustrated in FIG. 6.

Hereinafter, a detailed description of the configuration overlapping with the first and second embodiments of the present invention described above will be omitted.

Referring to FIGS. 5 to 9, a third embodiment of an inter-floor noise reduction structure (100'') may further include a plurality of support members (200) that are spaced apart from each other and interposed in a grid shape between the concrete slab (10) and the inter-floor member (110) in addition to the configuration of the first and second embodiments described above.

In addition, the inter-floor noise reduction structure (100'') may further include a support frame (160) installed between the adjacent support members (200), and a sound-absorbing plate (170) placed between the adjacent support members (200) and mounted on the support frame (160).

The plurality of buffer plates described later in the above-mentioned support member (200) can be manufactured using a known synthetic resin material having a certain elasticity, such as rubber.

In addition, the configuration of the supporting member (200) and the support frame (160) other than the buffer plate are manufactured using a known material having a certain rigidity, such as iron or alloy steel, and the sound-absorbing plate (170) can be manufactured using the same material as the sound-absorbing material.

That is, the concrete slab (10) and the interlayer member (110) can be stably maintained spaced apart from each other through the support member (200).

In addition, an air layer (180) is formed between the sound-absorbing plate (170) and the concrete slab (10) and between the sound-absorbing plate (170) and the interlayer member (110) through the sound-absorbing plate (170) mounted on the support frame (160), thereby further enhancing the sound-absorbing effect.

As shown in Fig. 10, the above inter-floor noise reduction structure (100'') may have a groove (171) formed at the corner of the sound-absorbing plate (170) corresponding to the outer surface of the connecting member (230) described later.

That is, by inserting the connecting member (230) into the judgment groove (171), the sound-absorbing plate (170) can be placed on the support frame (160).

Alternatively, although not shown in the drawing, a hole corresponding to the diameter of the connecting member (230) may be formed in the sound-absorbing plate (170), and the connecting member (230) may pass through the hole so that the sound-absorbing plate (170) may be mounted on the support frame (160).

Fig. 11 is an exploded perspective view of the support member and support frame illustrated in Fig. 6, and Fig. 12 is an 'A-A' section view illustrated in Fig. 8.

Referring to FIGS. 11 and 12, the support member (200) may include a lower support member (210) placed on the upper portion of the concrete slab (10), an upper support member (220) placed on the lower portion of the interlayer member (110), and a connecting member (230) installed between the upper support member (220) and the lower support member (210).

The above support member (200) can be connected to the upper support member (220) and the lower support member (210) in a vertically symmetrical manner with respect to the above connection member (230).

More specifically, the lower support member (210) may include a slab buffer plate (211) whose lower surface is in contact with the upper surface of the concrete slab (10), and a lower support block (212) whose upper surface of the slab buffer plate (211) is in contact with and fixed to the lower surface.

In addition, the lower support member (210) may include a lower pillar (213) formed vertically on the upper surface of the lower support block (212) along the height direction of the connecting member (230) and having an upper end joined to the lower end of the connecting member (230).

The upper support member (220) may include an interlayer member buffer plate (221) whose upper surface is in contact with the lower surface of the interlayer member (110), and an upper support block (222) whose lower surface of the interlayer member buffer plate (221) is in contact with and fixed to the upper surface.

In addition, the upper support member (220) may include an upper pillar (223) formed vertically on the lower surface of the upper support block (222) along the height direction of the connecting member (230) and coupled to the upper end of the connecting member (230).

The above inter-floor noise reduction structure (100'') has a lower column joining groove (231) formed on the lower surface of the connecting member (230) along the height direction of the connecting member (230), into which the upper end of the lower column (213) can be inserted.

And, an upper pillar joining groove (232) is formed on the upper surface of the connecting member (230) along the height direction of the connecting member (230), so that the upper end of the upper pillar (223) can be inserted.

That is, through the connection structure between the upper support member (220), the lower support member (210), and the connecting member (230), the support member (200) can more stably support the load transmitted along the stacking direction of the interlayer noise reduction structure (100'').

In addition, the inter-floor noise reduction structure (100'') has a lower protrusion (233) formed on the upper surface of the lower column coupling groove (231) along the height direction of the connecting member (230), and a lower protrusion coupling groove (214) formed on the upper surface of the lower column (213) along the height direction of the connecting member (230) so that the lower protrusion (233) can be inserted.

And, an upper protrusion (234) is formed on the lower surface of the upper pillar coupling groove (232) along the height direction of the connecting member (230), and an upper protrusion coupling groove (224) is formed on the lower surface of the upper pillar (223) along the height direction of the connecting member (230), so that the upper protrusion (234) can be inserted.

That is, since the connection structure between the upper support member (220), the lower support member (210), and the connecting member (230) is formed in a double manner, the upper support member (220) and the lower support member (210) can be more firmly connected to the connecting member (230), so that the support member (200) can support the load more stably.

The lower support member (210) may further include a connecting member lower buffer plate (215) that is fixed to the lower column (213) by having its lower surface in contact with the upper surface of the lower column (213) and that penetrates the lower protrusion (233) and has its upper surface in contact with the upper surface of the lower column connecting groove (231).

The upper support member (220) may further include a connecting member upper buffer plate (225) whose upper surface is fixed to the upper column (223) by contacting the lower surface of the upper column (223) and whose lower surface penetrates the upper protrusion (234) and contacts the lower surface of the upper column connecting groove (232).

The above connecting member (230) may further include a lower protrusion buffer plate (235) whose upper surface is in contact with the lower surface of the lower protrusion (233) and is fixed to the lower protrusion (233), and whose lower surface is in contact with the lower surface of the lower protrusion coupling groove (214).

In addition, the connecting member (230) may further include an upper projection buffer plate (236) whose lower surface is in contact with the upper surface of the upper projection (234) and is fixed to the upper projection (234), and whose upper surface is in contact with the upper surface of the upper projection coupling groove (224).

That is, by offsetting the vibration transmitted to the support member (200) along the stacking direction of the interlayer noise reduction structure (100'') through the plurality of buffer plates, interlayer noise can be reduced, and fatigue of the support member (200) can be reduced.

The above plurality of buffer plates can be fixed to the upper support member (220), the lower support member (210), and the connecting member (230) by means of the fixing member or a known adhesive member such as an adhesive, adhesive spray, or bond.

The above inter-floor noise reduction structure (100'') has a frame joining groove (237) formed on the outer surface of the connecting member (230) into which the end of the support frame (160) can be inserted.

Figures 13 and 14 are perspective views and exploded perspective views sequentially showing other examples of the connecting member and support frame illustrated in Figure 11, and Figures 15a and 15b are plan views sequentially showing the supporting frame and connecting member illustrated in Figure 14.

Referring to FIGS. 13 to 15b, the frame joining groove (237) may be formed on the outer surface of the connecting member (230') by extending a certain length from the upper surface of the connecting member (230') along the height direction of the connecting member (230').

In addition, a catch (161) is formed at the end of the support frame (160), and a catch-joining groove (238) is formed on the side of the frame joining groove (237) so that the catch (161) can be inserted.

Here, the above-mentioned hook-joining groove (238) may be formed on the side of the frame-joining groove (237) by extending a certain length from the upper surface of the above-mentioned connecting member (230') along the height direction of the above-mentioned connecting member (230).

That is, the support frame (160) can be inserted into the frame joining groove (237) and lowered along the frame joining groove (237) to be placed on the connecting member (230).

In addition, the state in which the above-mentioned hook (161) is caught in the above-mentioned hook engaging groove (238) is maintained, thereby preventing the above-mentioned support frame (160) from being unintentionally separated from the above-mentioned connecting member (230).

As described above, the inter-floor noise reduction structure according to one embodiment of the present invention can prevent moisture from penetrating into the inter-floor member when pouring lightweight foam concrete through a waterproof vinyl sheet.

Additionally, the sound absorption effect can be enhanced by dispersing and canceling out noise transmitted to the concrete slab and wall surface through lightweight foam concrete, interlayer members, and side members.

In addition, an air layer can be formed between the supporting members by a waterproof vinyl sheet fixed to the supporting members, and the sound absorption effect can be further enhanced by the air layer.

Additionally, a groove can be formed in the support member to further enhance the sound absorption effect.

As described above, the best embodiments have been disclosed in the drawings and specifications. While specific terminology has been used herein, it is solely for the purpose of describing the present invention and is not intended to limit the meaning or scope of the invention as defined in the claims. Therefore, those skilled in the art will understand that various modifications and equivalent embodiments are possible.
