Specific details for implementing the invention

[0013] Hereinafter, an inter-floor noise prevention mat for a building according to embodiments of the present invention will be described with reference to the drawings.

[0014] FIG. 1 is a cross-sectional view of a floor noise prevention mat for a building according to one embodiment of the present invention.

[0015] Referring to FIG. 1, the inter-floor noise prevention mat (100) of a building according to the present embodiment is applied to the floor surface of a building and can absorb inter-floor noise of the building, and includes a polyurethane resin layer (110), a fabric layer (140), and a fabric connecting layer (130).

[0016] The above polyurethane resin layer (110) is made of polyurethane and is a layer that absorbs inter-floor noise of the building, and can be formed in the shape of a wide plate with a certain area.

[0017] The fabric layer (140) is interposed between the polyurethane resin layer (110) and the floor surface of the building and is made of fabric, thereby preventing the formation of a mark of the polyurethane on the floor surface of the building as the polyurethane of the polyurethane resin layer (110) reacts with the floor surface of the building.

[0018] The fabric connecting layer (130) connects the polyurethane resin layer (110) and the fabric layer (140).

[0019] The fabric connecting layer (130) is formed in a coated form on the fabric layer (140), so that when the polyurethane resin layer (110) is foamed, the polyurethane resin layer (110) can be foamed on the fabric connecting layer (130) which is connected to the fabric layer (140).

[0020] In this embodiment, the fabric connecting layer (130) is characterized by preventing the polyurethane constituting the polyurethane resin layer (110) from transferring to the fabric layer (140) when the polyurethane resin layer (110) is foamed.

[0021] The fabric connecting layer (130) is composed of at least one of thermoplastic polyurethane (TPU) and the polyurethane, and can be coated on the bottom surface of the polyurethane resin layer (110).

[0022] When foaming the polyurethane resin layer (110), foaming is performed in a high-pressure environment. When only the fabric layer (140) is present, the polyurethane constituting the polyurethane resin layer (110) can pass through the fabric layer (140). In this case, the polyurethane that has passed through the fabric layer (140) can react with the floor surface of the building and leave marks on the floor surface of the building. However, in this embodiment, the polyurethane resin layer (110) is foamed with the fabric connecting layer (130) coated on the fabric layer (140), so that the polyurethane constituting the polyurethane resin layer (110) is blocked by the fabric connecting layer (130), thereby preventing transfer to the fabric layer (140).

[0023] An air circulation groove (115) is formed on the bottom surface of the polyurethane resin layer (110) in a recessed shape so that air circulation is possible between the bottom surface of the polyurethane resin layer (110) and the floor surface of the building.

[0024] The fabric layer (140) and the fabric connecting layer (130) are formed in a recessed shape in the same manner as the bottom surface of the polyurethane resin layer (110) in the air circulation groove (115). To this end, foaming of the polyurethane resin layer (110) is performed so that the fabric layer (140) and the fabric connecting layer (130) have groove shapes corresponding to the air circulation groove (115), thereby allowing the fabric layer (140) and the fabric connecting layer (130) to be connected to the bottom surface of the polyurethane resin layer (110) and the air circulation groove (115) to be formed.

[0025] A surface layer (120) for preventing yellowing, etc., can be coated on the above polyurethane resin layer (110).

[0026] As described above, the inter-floor noise prevention mat (100) of the above building comprises the polyurethane resin layer (110), the fabric layer (140), and the fabric connecting layer (130). Consequently, the fabric connecting layer (130) prevents the polyurethane constituting the polyurethane resin layer (110) from transferring to the fabric layer (140) when the polyurethane resin layer (110) is foamed, thereby preventing the formation of permanent marks caused by the polyurethane constituting the polyurethane resin layer (110) on the floor surface of the above building made of polyvinyl chloride.

[0027] Hereinafter, a floor noise prevention mat for a building according to another embodiment of the present invention will be described with reference to the drawings. In carrying out this description, any descriptions that overlap with those already described in the above-mentioned embodiment of the present invention will be omitted here.

[0028] FIG. 2 is a cross-sectional view of a part of a floor noise prevention mat for a building according to another embodiment of the present invention, and FIG. 3 is a cross-sectional view showing the part shown in FIG. 2 deformed when pressed.

[0029] Referring to FIG. 2 and FIG. 3 together, the inter-floor noise prevention mat of a building according to the present embodiment includes an additional circulation groove (250), a deformation support member (255), and a restoration member (260).

[0030] The additional circulation groove (250) is formed in a shape where the bottom surface of the fabric layer (240) is recessed so that air circulation is possible between the bottom surface of the fabric layer (240) and the floor surface (10) of the building, separately from the air circulation groove (215).

[0031] The above deformation support member (255) protrudes from the bottom surface of the additional circulation groove (250) and touches the bottom surface (10) of the building so that the bottom surface of the fabric layer (240) is positioned so as to be floating at a certain height above the bottom surface (10) of the building.

[0032] The above-mentioned restoration member (260) is inserted into the interior of the fabric layer (240) and provides elasticity so that the deformation support member (255) is restored to its original shape after deformation.

[0033] The additional circulation groove (250) is formed in a tapered shape that sinks inward toward the interior of the fabric layer (240) as it moves toward the center, and the deformation support member (255) protrudes downward from the bottom portion of the additional circulation groove (250) (the portion that sinks the most from the bottom surface of the fabric layer (240), and the bottom of the deformation support member (255) protrudes a certain length longer than the bottom surface of the fabric layer (240), so that when the bottom surface of the deformation support member (255) touches the floor surface (10) of the building, the bottom surface of the fabric layer (240) is lifted a certain height above the floor surface (10) of the building.

[0034] A pair of stoppers (256, 257) are formed on each of the two walls of the additional circulation groove (250) formed in a tapered shape, protruding toward the deformation support member (255).

[0035] The above restoration member (260) includes a restoration main body (261), a restoration one-sided extension (262), a restoration other-sided extension (263), and an extension support (264).

[0036] The above restoration body (261) is V-shaped and is inserted into the interior of the deformation support member (255) for a certain length along the longitudinal direction of the deformation support member (255).

[0037] The above restoration one-sided extension (262) is extended from one end of the restoration body (261) in a curved shape with a certain curvature and is inserted in a shape that spans the interior of the deformation support member (255), the fabric layer (240), and the interior of one of the stoppers (256, 257) (256).

[0038] The above restoration other side extension (263) is extended from the other side end of the restoration body (261) in a curved shape with a certain curvature and is inserted in a shape that spans the interior of the deformation support member (255), the fabric layer (240), and the interior of the other one (257) of the stoppers (256, 257).

[0039] The above extension support (264) connects the vertices of the restoration one-sided extension (262) and the restoration other-sided extension (263) and is inserted into the interior of the fabric layer (240) in a curved shape with a certain curvature.

[0040] The above restoration main body (261), the above restoration one-sided extension (262), the above restoration other-sided extension (263), and the above extension support (264) are integrally formed from an elastic material such as rubber, so that when the deformation support member (255) is elastically deformed, they are elastically deformed together and provide elastic force so that the deformation support member (255) is restored to its original shape.

[0041] In particular, the restoration body (261) is formed in a V-shape, the restoration one-sided extension (262) and the restoration other-sided extension (263) are each formed in a curved surface shape, and the extension support (264) is formed in a curved surface shape connecting the vertices of the restoration one-sided extension (262) and the restoration other-sided extension (263), so that the restoration member (260) is flexibly deformed together with the deformation support member (255) and then restored to a circular shape with a stronger elastic force, thereby achieving the restoration of the deformation support member (255) to a circular shape.

[0042] Normally, when not stepped on by a user, the deformation support member (255) maintains an upright form as shown in FIG. 2, so that the bottom surface of the fabric layer (240) is lifted at a certain height from the floor surface (10) of the building, and air can be circulated through the air circulation groove (215), the additional circulation groove (250), as well as through the gap between the bottom surface of the fabric layer (240) and the floor surface (10) of the building.

[0043] Then, when pressure is applied to the upper part of the inter-floor noise prevention mat of the building, such as when a user steps on it, as shown in FIG. 3, the deformation support member (255) is pressed by the pressure applied to the upper part of the inter-floor noise prevention mat of the building and is elastically deformed while tilting toward either one of the stoppers (256, 257) (256) or the other of the stoppers (256, 257) (257), and the elastic deformation of the deformation support member (255) continues until it comes into contact with either one of the stoppers (256, 257) (256) or the other of the stoppers (256, 257) (257). At this time, the bottom surface of the fabric layer (240) comes into contact with the floor surface (10) of the building, and the restoration member (260) is also elastically deformed together with the deformation support member (255).

[0044] Then, when the pressure applied to the upper part of the inter-floor noise prevention mat of the above building is removed, the deformation support member (255) is restored to its original shape by the self-elasticity of the deformation support member (255) and the elasticity of the restoration member (260), and again, as shown in FIG. 2, the deformation support member (255) maintains an upright shape so that the bottom surface of the fabric layer (240) is restored to a shape that is floating a certain height above the floor surface (10) of the above building.

[0045] When configured as described above, normally, when not stepped on by a user, the bottom surface of the fabric layer (240) is lifted at a certain height above the floor surface (10) of the building by the deformation support member (255), allowing air to circulate through the air circulation groove (215), the additional circulation groove (250), as well as through the gap between the bottom surface of the fabric layer (240) and the floor surface (10) of the building, thereby enabling smoother air circulation between the bottom surface of the fabric layer (240) and the floor surface (10) of the building. However, when pressure is applied from the upper part of the inter-floor noise prevention mat of the building, such as when a user steps on it, the deformation support member (255) elastically deforms, causing the bottom surface of the fabric layer (240) to come into full contact with the floor surface (10) of the building, thereby enabling stable walking for the user.

[0046] Although the present invention has been illustrated and described above with respect to specific embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as set forth in the following claims. However, it should be clearly stated that all such modifications and variations are included within the scope of the present invention. Industrial applicability

[0047] According to one aspect of the present invention, the inter-floor noise prevention mat for a building can prevent the formation of permanent marks caused by the polyurethane forming the polyurethane resin layer on the floor surface of a building made of polyvinyl chloride, so its industrial applicability is high.
