As shown in Figures 1 to 3, the present invention provides a clamp 30 to a plurality of struts 10 in a soundproofing facility installed so that noise generated from a road or the like is not transmitted to an adjacent residential facility, such that a collision of a vehicle or the like. In order to prevent the soundproofing from being easily damaged due to the description of the components as described above are as follows.

The guide bar 10 is installed at regular intervals on the road structure 1 installed at the side of the road. The guide bar 10 has a predetermined thickness and length in a vertical direction and is parallel to each other, and the front part 11 and the rear part 12 and the front surface thereof. The connection part 13 is vertically connected to the center of the part 11 and the rear part 12, and coupling parts 15 and 16 are formed at left and right sides of the connection part 13.

The sound insulation panel 20 is installed so that noise generated from a road or the like is not transmitted to an adjacent residential facility, and is coupled to the coupling parts 15 and 16 of the guide bar 10 in a vertical direction.

The clamp 30 is for fixing the post 40, which will be described later, to the guide bar 10 as shown in FIG. And, the insertion portion 32 is inserted into one side of the guide bar and the insertion portion 32 is formed at a right angle and is formed of a protrusion 33 formed with an insertion hole 34 to one side.

The clamp 30 allows the insertion part 32 of the clamp 30 to move the front part 11 or the rear part 12 of the guide bar 10 while the soundproof plate 20 is coupled to the guide bar 10. Receiving and fastening, the insertion hole 34 is formed in the left and right sides (33a, 33b) of the protrusion 33, the support (40) is inserted into the support (40).

In addition, through holes 35 are formed in the right and left sides 33a and 33b of the protrusions 33 of the clamp 30 to be fastened by the fastening means 39.

This is to tighten the clamping force of the clamp 30 with respect to the guide bar 10 by cutting the left and right sides 33a, 33b of the protrusion 33 of the clamp 30.

At this time, the fastening means 39 is preferably made of a bolt (39a), nut (39b), washer (39c).

Next, the strut 40 is a cylindrical shape having a predetermined thickness and is inserted into the insertion hole 34 of the above-described clamp so that the soundproof plate 20 is easily damaged from an external shock such as a vehicle or the clamp 30 to prevent the vehicle from leaving. ) And one or more numbers in the vertical direction of the guide bar 10.
