FRAME FOR NOISE BARRIER ENABLING TO ADJUST

CONNECTION ANGLE

Technical Field

[1] The present invention relates to a frame for a sound-proof panel, and more particularly to a frame for a sound-proof panel, in which the installation angle can be adjusted depending upon the slope of the road side where the sound-proof panel is installed. Background Art

[2] A sound-proof wall is one of road facilities, which is disposed between a noise source and a noise-absorption point to reflect, diffract and absorb the noise, thereby weakening the intensity of noise. Such sound-proof walls are categorized into a steel sound-proof wall, a concrete sound-proof wall, an acrylic transparent sound-proof wall, a wooden sound-proof wall and the like, depending upon materials forming the sound-proof wall. In recent years, transparent sound-proof walls have become popular along the road for purposes of collecting light to prevent freezing of the road and rapidly melting snow stacked on the road, and secure a wide visibility.

[3] FIG. 6 shows a conventional transparent sound-proof panel.

[4] Referring to FIG. 6, the conventional transparent sound-proof panel includes a transparent plate 400 and a frame surrounding the transparent plate. The frame is composed of a horizontal member and a vertical member. Both lengthwise end portions of the horizontal members 100a and 100b and the vertical members 200a and 200b, which forms the frame, is formed to be inclined at an angle of 45 degrees, and engaged with each other to insert the transparent plate using a separate connection member.

[5] However, since the vertical and horizontal members forming the frame are attached at their corners with each other, the frame tends to be distorted or the corner connection portions tend to become spaced apart, during transportation, installation or use thereof. On the other hand, in the case where a sound-proof panel is installed in a sloped road side, the vertical and horizontal members are required to adjust their connection angle to conform to the slope of the road side. However, the conventional frame is configured such that the lengthwise end portions of the vertical and horizontal members are cut and attached to each other. Thus, the connection angle cannot be easily and correctly adjusted under complicated field situations. Disclosure of Invention Technical Problem [6] The present invention has been made to solve the above problems in the art, and it is an object of the invention to provide a frame for a sound-proof panel, in which vertical and horizontal members forming the frame are firmly assembled to prevent distortion or detachment of the corner connection portion during transportation, installation or use thereof, and the installation angle can be adjusted depending upon the slope of the road side where the sound-proof panel. Technical Solution

[7] According to one aspect of the invention, there is provided a frame for a sound-proof panel, comprising: upper and lower horizontal members; left and right vertical members; four angle-adjusting members connected to lengthwise upper and lower portion of the left and right vertical members in an angle-adjusting manner, both end portions of the upper and lower horizontal members being connected to the angle- adjusting members.

[8] In an embodiment, the vertical member includes an insert groove formed in inner side face thereof over the entire length thereof, the sound-proof plate being inserted into the insert groove, and a connection groove portion is formed in the lengthwise upper and lower portion of the insert groove, a plurality of prominences and depression being formed in the connection groove portion. The angle-adjusting member includes a connection protrusion, the connection protrusion having a face corresponding to the connection groove portion of the vertical member, a prominence and depressing being formed in the connection protrusion.

[9] In an embodiment, the vertical member is configured that a receiving groove is formed at widthwise center of the connection groove portion and an elongated hole is perforated in the receiving groove. The angle-adjusting member is formed with a protrusion at widthwise center of the connection protrusion, the protrusion being inserted into the receiving groove of the vertical member, and a thread hole is formed in the protrusion, a bolt being fastened to the thread hole for connection with the vertical member.

Advantageous Effects

[10] According to the above frame for sound-proof panels, vertical and horizontal members forming the frame are firmly assembled, thereby enabling to prevent distortion or detachment of the corner connection portion during transportation, installation or use thereof. Further, the installation angle can be adjusted, depending upon the slope of the road side where the sound-proof panel is installed. Brief Description of Drawings

Best Mode for Carrying out the Invention

[18] Hereinafter, preferred embodiments of the invention will be explaine.d in detail with reference to the accompanying drawings. In the drawings, like elements are denoted by like reference characters. Details on well-known elements or functions will be omitted.

[19] FIG. 1 is an elevation schematically illustrating a frame for sound-proof panels according to an embodiment of the invention. FIG. 2 is a perspective exploded view showing a major part (portion "A" in FIG. 1) in a frame for sound-proof panels according to an embodiment of the invention. FIG. 3 is a perspective view showing major portions of a vertical member according to an embodiment of the invention. FIG. 4 is a perspective view showing an angle-adjusting member according to an embodiment of the invention.

[20] As illustrated in FIG. 1, a frame for sound-proof panels according to an embodiment of the invention includes upper and lower horizontal members 10a and 10b, right and left vertical members 20a and 20b, and four angle-adjusting members 30a, 30b, 30c and 30d connected to the upper and lower portions of the right and left vertical members 20a and 20b. Both end portions of the upper and lower horizontal members 10a and 10b are inserted into the angle-adjusting members.

[21] Referring to FIG. 2, the angle-adjusting member 30a is illustrated, which is connected in an angle-adjusting fashion to the upper horizontal member 10a and the left vertical member 20a.

[22] As shown in FIG. 1, the upper horizontal member 10a (the same as the lower horizontal member) is formed of a hollow tube member. Formed over the entire length of the upper horizontal member 10a is an insert groove 11, to which a sound-proof plate 40 is inserted. The reason why the upper and lower horizontal members 10a and 10b is formed of a hollow tube member is to reduce its weight. The overall shape of the horizontal members is not limited to one illustrated in the figure, but can be constructed in various other shapes. Inner side of the insert groove 11 is formed with an inclined face 12 at both sides of the insert groove 11 so that rain water or snow can easily flow down. The opposite inner side face thereof is formed with a receiving groove 14, to which a sound-proof packing is inserted to prevent noise from reaching the noise absorption point through between the sound-proof panels.

[23] Referring to FIGS. 1 and 2, the left vertical member 20a (the same as the right vertical member) includes an insert groove 11 formed at its inner side face over the entire length thereof. The sound-proof plate 40 is inserted into the insert groove 11. Formed in the lengthwise upper and lower portions respectively is a connection groove portion 21 where a plurality of prominences and depressions 211 is formed. A receiving groove 22 is formed at the widthwise center of the connection groove portion 21. An elongate hole 221 is perforated in the receiving groove 22. The prominences and depression 211 are formed perpendicular to the direction in which the insert groove 11 is formed. The connection groove portion 21 is formed in a concave and arch shape.

[24] As illustrated in FIGS. 1 and 3, the angle-adjusting member 30a (the same as in the other angle-adjusting member placed in the connection portion between the horizontal and vertical members) is assembled to the upper and lower portions respectively of the vertical members 20a and 20b so as to enable angular adjustment. The angle-adjusting member 30a includes a connection protrusion 31, which has a protruding face corresponding to the face of the connection groove portion 21 of the vertical members 20a and 20b. The connection protrusion 31 is formed with a prominence and depression 311. A protrusion 32 is formed in the widthwise center of the connection protrusion 31, which is inserted into the receiving groove 22 of the vertical members 20a and 20b. Formed in the protrusion 32 is a thread hole 321, to which a bolt is fastened to connect the vertical member. On the other hand, since the horizontal member is inserted into the angle-adjusting member, the outer configuration thereof corresponds to the sectional configuration of the horizontal member.

[25] FIG. 5 is a sectional view illustrating angle-adjustment using a frame for sound-proof panel according to an embodiment of the invention.

[26] First, in order to combine the angle-adjusting member with the vertical member, the protrusion 32 of the angle-adjusting member is inserted into the receiving groove 22 of the vertical member. The bolt is fastened to the thread hole 321 via the elongated hole 221, thereby temporarily fixing the angle-adjusting member and the vertical member to each other. At this state, the angle-adjusting member is rotated to a desired angle and then the bolt is fastened to combine the angle-adjusting member to the vertical member. Here, since a prominence and depression is formed in the contacting face between the vertical member and the angle-adjusting member respectively, the two combined members remain at the adjusted angle without slipping by external forces. In this way, the assembling of the angle-adjusting member and the vertical member is finished at the four corners, and thereafter, the upper and lower horizontal members are inserted into and fastened to the angle-adjusting member, thereby completing assembling of the frame for sound-proof panels.

[27] As illustrated in FIG. 5 (a), (b) and (c), in any case where the corner of a sound-proof plate forms a right angle, an obtuse angle or an acute angle, separate horizontal and vertical members forming the frame need not to be prepared or processed, but only the sound-proof plate to be inserted inside the frame is required to be processed accordingly. In the present invention, the materials for the sound-proof plate are not particularly limited, but all kinds of well-known sound-proof plates can be employed.

[28] While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention. Industrial Applicability
