The mat main body 20 is constituted as follows.

The mat main body 20 is injection-molded by synthetic resin, and an upper surface thereof is formed with a coupling groove 21, and a supporting frame 22 is formed on the rim.

The cutting line 24 is formed longitudinally and laterally on the bottom 23 of the coupling groove 21 so that the mat main body 20 can be cut off and separated into four sheets 26 as required, An uneven protrusion 25 is formed on the inner surface.

At this time, the separation plate 26 cut through the cutting line 24 can be divided into four or more sheets as necessary.

The reinforcing protrusions 27 are formed longitudinally and laterally on the bottom surface of the mat main body 20 so as to reinforce the rigidity of the mat main body 20 and improve moldability and to form the binding tube 28 at equal intervals .

The binding tube 28 is formed at each corner of the bottom surface of each of the separating plates 26 constituting the mat main body 20 and at the center of both sides thereof so that even if the separating plate 26 is cut along the cutting line 24, Stable installation is possible.

The cushion pad 30, which is engaged with the coupling groove 21 of the mat main body 20, is constructed as follows.

The buffer pad 30 is injection-molded with a foamed resin having a cushion, and can be separated into four sheets to be joined to the coupling groove 21.

The ridges 35 of the buffer pads 30 constitute the ridges 35. The four buffer pads 30 are assembled into a single piece through the ridges 35. The ridges 35 of the buffer pads 30, The cushioning pad 30 is firmly engaged with the engaging groove 21 of the mat main body 20 by engaging with the concave and convex protrusions 25 formed on the support frame 22 of the mat main body 20.

Even when the buffer pad 30 is engaged with the coupling groove 21 of the mat main body 20, a part of the upper end of the buffer pad 30 protrudes slightly higher than the support frame 22.

At this time, the cushion pad 30 is divided into a plurality of sheets such as the separating plate 26 of the mat main body 20, which is cut and separated through the cutting line 24.

The buffer footrest 40 fitted to the bottom binding tube 28 of the mat main body 20 is made of a synthetic resin excellent in cushioning and buffering effect like urethane resin and has an upper fitting portion 42 formed at the upper end thereof, So as to be stably supported and configured to be easy to absorb impact when the impact is transmitted.

When the fitting portion 42 of the cushioning foot 40 having the above-described structure is coupled to the coupling tube 28, a space 41 is formed between the bottom 43 and the mat body 20 as shown in FIG. So that the impact to be cut on the upper surface of the mat main body 20 is blocked without being directly transmitted to the bottom 43.

According to the present invention constructed as described above, the noise preventing mats 10 are installed on the floor of a place where the noise preventing mats 10 are to be installed.
