The present invention relates to a structure of a frame used as a window frame of a panel in a transparent soundproof plate, which is one of the panel members of a soundproof wall installed on a roadside and a railroad side to block and reduce noise.

 In general, the dominant load applied to the sound insulation board is the horizontal wind load, and in the transparent sound insulation board, the horizontal wind load is supported by the cross-sectional stiffness of the frame and transferred to the sound wall wall support. Therefore, the structure of the frame that plays such a structural role should have an efficient cross-sectional configuration according to the direction of the horizontal wind load, and in this way, there is no breakage due to the wind load, and at the same time, there is little deflection in the wind load direction. There should be no departure.

The conventional transparent sound insulation board has a structure in which the upper and lower frames and two side frames are combined in a set of window frames as shown in FIG. 7. The upper and lower frames are in contact with the upper and lower frames of another set of window frames stacked corresponding to the upper and lower parts, and the two side frames are fixed to respective struts installed along the extension of the soundproof wall. In addition, the cross section of the frame constituting the window frame has a generally rectangular pipe shape that forms one or two spaces therein, as shown in FIG. 8, and a groove into which the transparent panel is inserted in the direction of binding the transparent panel. Is provided and the corresponding surface is a structure including a coupling protrusion or coupling groove for coupling with another frame member of the set. Therefore, the conventional frame cross section is not the cross section which concentrates the cross section rigidity with respect to the direction to which a wind load is applied, although the function as a window frame which binds a transparent panel is efficient. Therefore, in the conventional frame structure, in order to secure the resistance performance of the frame against horizontal wind load, the outside size of the frame must be larger than necessary, resulting in economical loss and deterioration of aesthetic performance due to the shape of the enlarged frame. There is.

Accordingly, the present invention improves the cross-sectional shape of the conventional transparent soundproof panel frame to improve the cross-sectional shape and coupling structure to selectively excellent cross-sectional rigidity with respect to the direction in which the horizontal wind load is applied to secure the resistance to horizontal wind load even with a small frame And it minimizes the deflection in the direction of load and provides the technology to improve the structural efficiency, economic efficiency and aesthetics of the transparent sound insulation board by allowing the user to selectively adjust the rigidity of the frame.

The present invention for the above-mentioned 'frame structure of the transparent soundproof plate excellent in the cross-sectional rigidity in the selective direction' effectively improves the flat cross-sectional shape of the frame side portion most susceptible to bending deformation caused by wind load in the conventional transparent soundproof plate frame structure It provides a function to intensively improve the resistance performance against the direction of the wind load. In addition, by dividing the conventional one-piece frame structure into two separate members so that the connection method between the individual members is a structurally very efficient way to provide a method that the user can selectively adjust the rigidity of the frame.

In the cross section of the frame, the direction in which the transparent panels 4 are coupled is set upward, and the opposite direction corresponding thereto is set downward, and the direction perpendicular to the up and down directions is passed through the first lateral direction and the second lateral direction. When the configuration of the present invention is described with reference to the drawings, the outer side (1-1) having a plurality of curved surfaces of the continuous 'l' shape in the up-down direction to the outer side in the first lateral direction is mutually symmetrical Corresponding to the upper and lower ends of the outer portion (1-1) and the upper cover (1-6) and the lower cover (1-7) respectively connected to form a closed cross-section, the central portion of the upper cover '∪' shape A transparent panel inserting portion (1-5) of which is symmetrically corresponding to the bottom surface together with the bottom surface of the transparent panel inserting portion (1-5) and at the top of the central portion of the reinforcing member when the internal reinforcing member (2 or 3) is inserted; Flange release of '∩' shape to support lower surface to prevent buckling Stand (1-4) is provided, the inner side facing the outer side (1-1) of the corresponding 'up and down' in order to fix and support both ends of the reinforcement when the inner reinforcement (2 or 3) is inserted -A 'web-shaped web breaker 1-2 and a' T'-shaped web axial support are provided to provide the body frame 1 in which the same cross-sectional shape in the second lateral direction as a whole extends by a predetermined length.

In addition, a flange (2-) having a web (2-2) inserted into the main body frame (1) and responsible for the axial resistance to wind load, and responsible for the distribution of bending energy at both ends of the web (2-2). 1) to provide the type I reinforcement (2) having the 'I' shape to increase the overall cross-sectional secondary moment.

In addition, it is possible to provide another form of reinforcement that can be inserted into the body frame (1), specifically divided by a plurality of partitions (3-1) therein and the outer housing portion (3- It provides a hollow grid reinforcement (3) having a plurality of voids (3-1) surrounded by 3).

In addition, the curved surface of another shape besides the curved surface of the letter 'r' which is a structurally efficient shape can effectively resist the shape of the outer frame 1-1 of the main body frame 1 against the direction in which the horizontal wind load is applied. In detail, the outer side 1-1 having a plurality of '-' protrusions provided at predetermined intervals in the up-down direction may be provided on the first lateral facing inner side of the main body frame 1. In addition, the outer side 1-1 having a plurality of semi-circular protrusions with a predetermined interval in the up-down direction may be provided on the outer side of the first lateral direction.

The present invention provides a function of intensively improving the resistance to wind load by providing a cross-sectional structure of the frame to form various types of projections or bends with respect to the direction in which the horizontal wind load is applied.

The present invention also provides a user-friendly method of designing a unitary frame structure, which is divided into a main body frame and a reinforcement member inserted into the main body frame, and a connection method between the individual members to be a structurally efficient method. It provides a way to selectively adjust the stiffness.

Therefore, the present invention can centrally and selectively improve the cross-sectional stiffness of the frame with respect to the direction in which the wind load is applied to the transparent soundproof plate, so that the outer size of the frame does not need to be larger than necessary, and economical benefits can be realized thereby. In addition, it is possible to prevent the deterioration of the aesthetic performance of the transparent sound insulation board due to the shape of the existing enlarged frame through the present invention.
