Abstract

The present invention discloses an assembly-type cushion mat for preventing interlayer noise, comprising: a body formed in a flat shape; a plurality of coupling grooves formed to be recessed inward at regular intervals on the lower edge of the body; a coupling projection formed to protrude outwardly on the edge surface of the body to correspond to the coupling grooves and fitted into the coupling grooves of another mat placed adjacently; a recess formed to be recessed downward on the upper surface of the coupling projection; and a protruding portion formed to correspond to the recess on the surface facing the upper surface of the coupling projection of another mat placed adjacently among the coupling grooves and fitted into the recess of another mat placed adjacently.

Description

Assembling-Type Cushion Mat for Noise Reduction Between Floors The present invention relates to a prefabricated cushion mat used to protect a person from injury even if they fall on an indoor floor, or to install on the upper surface of a concrete slab forming the floor between floors within a unit of a multi-story building such as an apartment, so as not to transmit noise generated on one floor to another floor through the lower part of the floor structure. More specifically, the invention relates to a prefabricated cushion mat for preventing inter-floor noise that effectively absorbs and mitigates impact applied to the floor even when subjected to repeated loads for a long period of time, thereby improving the performance of damping impact noise between floors, and also maintains a strong bonding force between mats to maximize stability against mechanical deformation. Recently, conflicts and disputes regarding inter-floor noise between neighbors in apartment buildings, caused by children running or adults walking, have resulted in property damage and even led to violent crimes resulting in loss of life, thereby lowering the quality of life for residents of apartment buildings. In general, cushion mats are being installed as part of efforts to reduce inter-floor noise issues among residents in multi-unit housing, create a pleasant living environment, and establish a safe child-rearing environment so that children do not get injured even if they fall. For example, cushion mats are widely used in multi-purpose facilities such as kids cafes, daycare centers, and nursing homes for the purposes of preventing falls, musculoskeletal disorders, and relieving fatigue, as well as to reduce inter-floor noise in various multi-story buildings such as apartment buildings, officetels, dormitories, multi-family houses, and multi-occupancy facilities. As an example of prior art related to this, a ‘floor noise prevention mat’ has been disclosed in Patent Document 1. As illustrated in FIG. 1, it comprises a first cushioning member (11) in the shape of a flat plate, a connecting member (12) that is horizontally connected and detachable from a connecting member provided on another mat that is adjacent and is positioned along the edge of the first cushioning member (11), and a second cushioning member (13) that is positioned on the lower surface of the first cushioning member (11) and forms an air layer between the bottom and the lower surface of the first cushioning member (11). In particular, the connecting member (12) is formed protruding outward from the first cushioning member (11) and includes a connecting member (121) that is detachably connected to a connecting groove provided on another mat that is adjacent and is formed recessed inward from the first cushioning member (11) and is detachably connected to a connecting member provided on another mat that is adjacent. A conventional mat of this type can minimize the area in direct contact with the floor by forming a cushioning cell (131) with a honeycomb structure and an air groove (131A) on the lower surface, and can ensure smooth air circulation and breathability, as well as maximize cushioning and sound absorption, thereby minimizing the transmission of vibration and noise to the lower layer. Additionally, as shown in FIG. 2, the coupling member (121) has a first hook-shaped hook member (121A) formed therein that is hooked and supported by a coupling groove provided in another mat arranged adjacently, and the coupling groove (122) has a second hook-shaped hook member (122A) formed therein that is hooked and supported by a coupling member provided in another mat arranged adjacently. Accordingly, the bonding strength between the mats is high, restricting free flow and preventing easy separation and detachment even when external force is applied. However, such conventional mats are made of polyurethane foam, and due to the characteristic that their properties change over time, when used for a long period, the bonding force between the connecting part with another mat, that is, the connecting member (121) and the connecting groove (122), gradually weakens. Additionally, there is a problem in that they easily lift or separate due to external forces as they repeatedly contract and expand due to seasonal temperature differences. In addition, if left on the floor for a long time, poor air circulation between the mat and the floor causes moisture to accumulate, leading to mold growth and posing a problem that negatively affects hygiene and health.
