As the second vertical frame 40 and horizontal frame 22, generally, an extruded profile made of an aluminum alloy is cut to an appropriate length and subjected to predetermined processing such as drilling or notching, but aluminum is used. Other metals or synthetic resins may be used instead of the alloy.

Next, the relationship between the first panel 10 and the second panel 20 will be described in detail. As shown in FIG. 4, the second panel 20 is arranged behind the first panel 10.

More specifically, the second vertical frame 40 is an outer peripheral portion on the side opposite to the side on which the panel main body 21 is arranged, and has an engaging projection 43 protruding in a direction opposite to the opening direction of the groove portion 41. The engaging protrusions 43 are continuously formed along the vertical direction, which is the longitudinal direction of the second vertical frame 40. On the other hand, the first vertical frame 30 is an outer peripheral portion on the side opposite to the side on which the panel main body 11 is arranged, is formed on the side opposite to the groove portion 31, and engages with the engaging projection 43. It has a recess 33, and the engaging recess 33 is continuously formed along the vertical direction which is the longitudinal direction of the first vertical frame 30.

It includes a side regulating portion 33b protruding across the direction and a rear regulating portion 33c protruding from the side regulating portion 33b to the rear surface side of the engaging projection 43.

As a result, the movement of the engaging projection 43 in the front-rear direction is restricted by the front regulation unit 33a and the rear regulation unit 33c, and the movement in the protrusion direction is restricted by the side regulation unit 33b. Since the first vertical frame 30 and the second vertical frame 40 are arranged at the left and right ends of the first panel 10 and the second panel 20, respectively, the second panel 20 is attached to the first panel 10. On the other hand, movement in the front-back direction and the left-right direction is restricted. Further, since the engaging protrusion 43 can move in the vertical direction in which the movement is not restricted by the engaging recess 33, the second panel 20 can slide in the vertical direction with respect to the first panel 10. Is made.

FIG. 9 is an enlarged cross-sectional view taken along the line DD of FIG. In FIG. 9, although the second panel 20 does not appear, it is shown by a broken line to explain the positional relationship. In the first vertical frame 30, a connecting member 50 is attached to a side wall portion 31a on the rear side of the groove portion 31. The connecting member 50 includes a fixing portion 51 fixed to the side wall portion 31a, and a retaining portion 52 projecting rearward from the fixing portion 51 and intersecting the second vertical frame 40 in a plan view. When the second panel 20 slides downward with respect to the first panel 10 by the retaining portion 52, the lower limit of the slide is the position where the second vertical frame 40 comes into contact with the retaining portion 52. Therefore, it does not fall out of the first panel 10.

Next, a temporary fixing means for temporarily fixing the second panel 20 at an appropriate position when the second panel 20 is slid in the vertical direction with respect to the first panel 10 will be described. 10A and 10B are enlarged cross-sectional views taken along the line EE of FIG. 3, where FIG. 10A shows a slidable state and FIG. 10B shows a temporarily fixed state. In the first vertical frame 30, a guide portion 34 for temporarily fixing the second vertical frame 40 is provided in a side wall portion 31a on the rear side of the groove portion 31 at a location different from the location where the connecting member 50 is attached. ing. The guide portion 34 is formed in a groove shape that opens toward the rear side along the vertical direction that is the longitudinal direction of the first vertical frame 30, and in this embodiment, it has a bag groove shape and is on the opening side. The width is narrower than the width on the back side. A temporary fixing member 35 that can move in the vertical direction is arranged in the guide portion 34. The width dimension of the temporary fixing member 35 in the left-right direction is slightly narrower than the width dimension on the back side of the guide portion 34, whereby rotation of the temporary fixing member 35 about the front-rear direction, which is the thickness direction, is restricted. Further, it has a screw hole 35a that penetrates in the thickness direction and leads to the opening of the guide portion 34.

The second vertical frame 40 has a through hole (not shown) that penetrates in the front-rear direction and penetrates toward the opening of the guide portion 34 at a position corresponding to the guide portion 34. The mounting bolt 44 is inserted into the screw hole 35a, and the screw portion of the mounting bolt 44 is screwed into the screw hole 35a of the temporary fixing member 35.

As a result, as shown in (a), when the mounting bolt 44 is simply screwed into the temporary fixing member 35, the temporary fixing member 35 can slide in the guide portion 34 in the vertical direction. The second panel 20 can be slid up and down with respect to the first panel 10. Then, after adjusting the vertical position of the second panel 20 to an appropriate position, as shown in (b), when the mounting bolt 44 is retightened with respect to the temporary fixing member 35, the temporary fixing member 35 becomes a guide portion. It will be in a fixed state within 34. As a result, the second panel 20 can be temporarily fixed to the first panel 10 at that position.

Next, a fixing structure for fixing the soundproof panel 100 to the fixing means 60 will be described. 11 is an enlarged sectional view taken along line FF of FIG. 1, and FIG. 12 is an enlarged sectional view taken along line GG of FIG. In FIG. 12, the second panel 20 does not appear, but the second panel 20 and the members related thereto are shown by broken lines in order to explain the positional relationship. As shown in FIGS. 2 and 11, the fixing means 60 includes a plurality of vertical columns 61 erected at appropriate intervals in the left-right direction with respect to the installation surface, and horizontal columns 62 attached between the vertical columns 61. , A fixing member 63 for fixing the first panel 10 and the second panel 20 is provided. In this embodiment, the fixing member 63 is fixed to the horizontal support 62.

Further, as shown in FIG. 12, the first panel 10 and the second panel 20 are provided with a first connecting portion 53 and a second connecting portion 45 for connecting to the fixing member 63, respectively. The first connecting portion 53 is formed toward the rear from the connecting member 50 attached to the first vertical frame 30. The second connecting portion 45 is formed so as to project rearward from the second vertical frame 40. Since the fixing member 63 can be connected to both the first connecting portion 53 and the second connecting portion 45, if one type of fixing member 63 is prepared, the first connecting portion 53 can be connected via the fixing member 63. By connecting the second connecting portion 45 and the second connecting portion 45, the first panel 10 and the second panel 20 can be fixed to the fixing means 60.

Further, since the soundproof panel 100 is installed so as to surround the construction site, it is continuously arranged in the left-right direction. Therefore, when the soundproof panel 100 is fixed, the position is within the width of the soundproof panel 100 in the left-right direction. Need to be fixed with. In addition, it is necessary to secure a space behind the first panel 10 so that the second panel 20 can slide in the vertical direction to avoid interference with the fixing member 63. Therefore, the connecting member 50 is attached to the lower end of the first vertical frame 30, and the connecting member 50 is provided with the first connecting portion 53, after each of the first connecting portion 53 and the second connecting portion 45. At the ends, they are aligned in the front-back direction. As a result, the soundproof panel 100 can sufficiently secure the adjustment range of the height position of the second panel 20 with respect to the first panel 10, and the front and rear positions of the fixing member 63 are also aligned. , Even if there is no special adjustment, it will be arranged along the vertical direction, and it will be less likely to tilt to the front side or the rear side. In this embodiment, the rear ends of the first connecting portion 53 and the second connecting portion 45 are arranged in contact with the horizontal support 62, and the horizontal support 62 is aligned with the vertical support 61. Since they are attached, the rear ends of the first connecting portion 53 and the second connecting portion 45 having different height positions can be easily aligned in the front-rear direction.

Further, the second connecting portion 45 is continuously formed along the vertical direction which is the longitudinal direction of the second vertical frame 40. Here, the second panel 20 is not a fixed position because the height position is determined according to a required height such as the ceiling height at the installation location, but the height position of the horizontal column 62 of the fixing means 60 is If it is within the range of the second connecting portion 45 formed in the vertical direction, it can be fixed at that position.

13 is a cross-sectional view taken along the line HH of FIG. 9, and FIG. 14 is a rear view of FIG. 13. In each case, (a) is a case where the second panel 20 is in an intermediate position in the vertical movable range. b) shows the case where the second panel 20 slides downward and is in the lower limit position. In (a), when the second panel 20 is further moved downward in the Y direction, the operator is near the lower end of the groove 41 of the second vertical frame 40, or near the horizontal frame 22 located near the groove 41. If you have, your hand or finger may be caught between the connecting member 50 and the retaining portion 52.

Here, FIG. 9 shows the relationship between the first vertical frame 30 and the second vertical frame 40, that is, the second vertical frame 40 does not fall out downward due to the retaining portion 52 on the side of the first vertical frame 30. However, in the present embodiment, as shown in FIGS. 13 and 14, the horizontal frame 22 attached to the lower end of the second vertical frame 40 comes into contact with the retaining portion 52. It may prevent the second vertical frame 40 from falling out downward. That is, the second panel 20 does not have to fall out of the first panel 10.

15 and 16 are explanatory views showing another embodiment of the soundproof panel 100 according to the present invention, in which FIG. 15 corresponds to FIG. 13 and FIG. 16 corresponds to FIG. (A) shows the case where the second panel 20 is in the intermediate position in the movable range in the vertical direction, and (b) shows the case where the second panel 20 is in the position where the second panel 20 is slid downward.

In the first panel 10, a spacer 36 is arranged inside the guide portion 34 of the first vertical frame 30 along the longitudinal direction, and the upper end portion 36a of the spacer 36 is from the upper end portion of the connecting member 50. Is also located above. A stopper 46 is attached to the lower end of the second panel 20. In this embodiment, a part of the lower end portion 46a of the stopper 46 can move in the guide portion 34. Therefore, when the second panel 20 moves downward, the lower end portion 46a of the stopper 46 comes into contact with the upper end portion 36a of the spacer 36. As a result, the stopper 46 is locked to the spacer 36, so that the second panel 20 does not move further downward.

As a result, a gap S is created between the stopper 46 and the retaining portion 52 of the connecting member 50. As a result, even if the operator has the horizontal frame 22 located near the groove 41 of the second vertical frame 40 or near the groove 41, the hand or finger can be caught between the stopper 46 and the retaining portion 52. Things are less likely to happen. That is, when the second panel 20 is held as described above, the operator is on the rear side of the soundproof panel 100, so that the first panel 10 is arranged on the front side of the soundproof panel 100. The spacer 36 is also arranged in front of the connecting member 50. Therefore, when the operator holds the second panel 20, he / she holds a different part from the stopper 46, or when he / she holds the vicinity of the stopper 46, he / she holds the rear side, thereby holding a hand between the stopper 46 and the spacer 36. And fingers are less likely to get caught.

The stopper 46 may include a lower plate portion 46b including a lower end portion 46a, and a part of the stopper 46 may be arranged in the guide portion 34 and can come into contact with the upper end portion 36a of the spacer 36. Like the form, it may have a front plate portion 46c arranged in the guide portion 34. As a result, the front plate portion 46c can be formed into a form (not shown) that also serves as the temporary fixing member 35. Further, as in this embodiment, it may have a rear plate portion 46d located behind the groove portion 41 of the second vertical frame 40.

The temporary fixing member 35 and the stopper 46 may be separate bodies or may be integrally formed although not shown. That is, if it is set as a separate body, the temporary fixing position of the temporary fixing member 35 can be arbitrarily set. On the other hand, since the temporary fixing member 35 and the front plate portion 46c of the stopper 46 are both arranged in the guide portion 34, the front plate portion 46c is temporarily fixed by providing the screw holes 35a in the front plate portion 46c. It can be used as a member 35.

The soundproof panel 100 according to the present invention is a soundproof panel 100 fixed to the fixing means 60, and is located on the rear side of the first panel 10 and the first panel 10 in the thickness direction of the first panel 10. It is provided with a second panel 20 that is overlapped and slidably connected in the vertical direction, and a temporary fixing means for temporarily fixing the second panel 20 at a predetermined height position with respect to the first panel 10. The first panel 10 regulates the downward slide of the second panel 20 and includes a connecting member 50 connected to the fixing means 60. In the second panel 20, a second connecting portion 45 that projects rearward and is connected to the fixing means 60 is formed along the vertical direction.

As a result, the second panel 20 can be temporarily fixed at a predetermined position with respect to the first panel 10, so that the height of the soundproof panel 100 can be easily adjusted, and after the temporary fixing work, any arbitrary one can be used. Since the second panel 20 can be fixed to the fixing means 60 such as a support column at the height position, the workability is excellent.

Further, in the soundproof panel 100 according to the present invention, in the first panel 10, the second panel 20 is above the height position where the second panel 20 is restricted from sliding downward by the temporary fixing member 35. The spacer 36 to be locked may be provided.

As a result, when the second panel 20 slides downward, the operator's hand may be caught between the connecting member 50 and the retaining portion 52, but the spacer 36 suppresses such a problem. Can be done. Further, if the spacer 36 is arranged in front of the connecting member 50, a problem is less likely to occur so that the operator's hand is pinched between the second panel 20 and the spacer 36.

Although the soundproof panel of the present invention has been described above based on the embodiments, the present invention is not limited to these embodiments.
