It is fixed to the column 1. On the other hand, the vertical frame 31 of the frame 3 is provided with a projecting piece 34 that extends in the vertical direction and protrudes to the side, the projecting piece 34 is disposed on the front side of the front plate 41, and a cover material on the front side thereof. 5 are arranged, and these are connected to each other by a fixing bolt B2 inserted in the front-rear direction. Thereby, the vertical frame 31 is attached to the support column 1 with almost no gap with respect to the support column 1. Note that the structure for fixing the vertical frame 31 to the support column 1 is not limited to this embodiment, and although not shown, for example, without using the support member 4, the vertical frame 31 or the protruding piece 34 of the vertical frame 31 is connected to the support column 4. 1 may be fixed.

  The upper horizontal frame 32 and the lower horizontal frame 33 are generally obtained by cutting a long shape material formed by extrusion molding of an aluminum alloy into an appropriate length, and the frame body 3 as with the louver material 2. Between the vertical frames 31. As for the upper horizontal frame 32 and the lower horizontal frame 33, the upper horizontal frame 32 and / or the lower horizontal frame 33 may not be used, and the louver material 2 may be used instead.

  Next, the connection structure between the louver member 2 and the frame 3 will be described in detail with reference to FIGS. In this embodiment, the left and right vertical frames 31 of the frame body 3 are formed in an L shape in which a fixed surface portion 35 is formed opposite to a side end portion of the louver material 2, and provided on the fixed surface portion 35. The louver material 2 is fixed between the vertical frames 31 by fixing screws B3 screwed into the longitudinally extending screw holes 21 provided on the inner wall surface near the top of the louver material 2 through the through holes 36. doing.

  In this embodiment, vertical ribs 37 extending in the vertical direction at the front and rear ends of the fixed surface portion 35 of the vertical frame 31 protrude in the direction of the louver material 2. Since the dimension between the front and rear vertical ribs 37 is slightly wider than the front and rear width of the louver material 2, the side end portion of the louver material 2 is inserted between the vertical ribs 37 when fixing with the fixing screw B 3. If this is done, the alignment operation between the through hole 36 of the fixed surface portion 35 and the screw hole 21 of the louver material 2 becomes easy, and after the fixing operation, there is one screw hole 21 provided in the louver material 2. In addition, it is possible to suppress unnecessary positional deviation such as rotation of the louver material 2 around the fixing screw B3. Furthermore, since the side edge part of the louver material 2 is hidden by the vertical ribs 37 in a front view, the design can be improved without exposing the side edge part.

  As in this embodiment, one screw hole 21 may be provided, but a plurality of screw holes are provided and a plurality of fixed screws are used to connect the fixed surface portion 35 of the vertical frame 31 and the louver material 2. It is good also as a form to do.

  Next, the louver material 2 will be described in more detail. The louver member 2 has a hollow body whose upper part is formed in a mountain shape by two slope parts 22 and two side parts 23 are formed opposite to each other below the slope part 22 and opened downward. Formed from. Such a louver material 2 is generally used by cutting an elongated material obtained by extrusion molding of an aluminum alloy into an appropriate length. In this embodiment, the screw hole 21 for attaching the louver material 2 to the vertical frame 31 is provided on the inner wall surface near the top in the mountain-shaped upper portion of the louver material 2, but its position is particularly limited. It is not a thing.

  A sound absorbing material 6 is provided between the upper portions of the side surface portions 23. The sound-absorbing material 6 is generally a sound-absorbing material such as a glass wool mat, a rock wool mat, a mat made of synthetic resin fibers, or the like, and these are covered with a fluorine resin or the like. It is formed in a substantially rectangular shape and has a horizontal plate shape in which the sound absorbing material 6 is internally provided along the longitudinal direction of the louver material 2. As the sound absorbing material 6, a material created to have a length corresponding to the length of the louver material 2 may be used, or a plurality of the sound absorbing materials 6 arranged in the longitudinal direction of the louver material 2 may be used. In the case of the latter, you may arrange | position with a clearance gap between the sound-absorbing materials 6, and may arrange | position without a clearance gap.

  The sound absorbing material 6 is housed between the upper portions of the side surface portions 23 of the louver material 2, and in this embodiment, the mountain-shaped upper portion of the louver material 2 is not opened, so that depending on the influence from the upper portion, the sound absorbing material 6 Since the surface of the material 6 is hardly scratched and is not directly hit by rainwater or the like, the performance of the sound absorbing material 6 is hardly deteriorated, and the sound absorbing property can be maintained for a long time.

Thereby, the ventilation property can be ensured through the gap before and after the bag P. In addition, noise generated by the passage of an automobile from the front side of the kite P enters the sound absorbing material 6 through the gap and can be absorbed by the sound absorbing material 6. Noise transmission can be suppressed. Further, since the upper portion of the louver material 2 is mountain-shaped as described above, noise that has entered from the gap between the louver materials 2 propagates along the slope portion 22 and easily enters the lower surface of the sound absorbing material 6. preferable.

  Furthermore, in this embodiment, since the space portion 26 is formed by the upper surface of the sound absorbing material 6 and the inner surfaces of the two slope portions 22, even if noise passes through the sound absorbing material 6, The noise can be effectively reduced by being reflected on the peripheral surface and reabsorbed by the sound-absorbing material 6, noise being attenuated by the reflection, or noise being canceled by the reflection. .

  Further, the upper portion of the slope portion 22 of the lower louver material 2 is inserted between the lower portions of the side surface portions 23 of the upper louver material 2, which is seen from the front-rear direction, and the slope portion 22 of the lower louver material 2. Since the upper portion of the upper portion and the lower portion of the side surface portion 23 of the upper louver material 2 overlap, the line of sight in the front-rear direction is blocked and a blindfold function is also provided.

  6-7 is the elements on larger scale of the louver material 2 vicinity in other embodiment of the ridge P which concerns on this invention. In this embodiment, compared with the ridge P shown in FIGS. 1 to 5, the upper protrusions 24 provided between the upper portions of the side surface portions 23 of the louver material 2 are connected to each other to form a bottom surface portion 27. The point is mainly different. Thereby, regardless of the presence or absence of the sound absorbing material 6, a space portion 26 as a closed space is formed on the upper portion of the louver material 2 by the two slope portions 22 and the bottom surface portion 27. Furthermore, two screw holes 21 provided in the upper part of the louver material 2 are provided in the front and rear, and can be more firmly fixed to the vertical frame 31. Therefore, although the vertical rib 37 provided in the vertical frame 31 shown by FIGS. 1-5 is not provided in this form, it is good also as a form provided with the vertical rib 37. FIG.
