Description

  The present invention relates to a soundproof panel frame attached to the outer periphery of a soundproof panel body, and a soundproof panel including the soundproof panel frame.

  In order to reduce noise spreading to the surroundings, soundproof panels are used at construction sites. The soundproof panel has a frame attached around a substantially rectangular panel body. Since the soundproof panel is substantially flat even if it includes a frame, it is often stacked and temporarily placed. The frame functions as a function for preventing displacement during stacking and as a handle for carrying.

  Patent Document 1 discloses a frame of a soundproof panel that is not deformed due to stacking and is easy to handle during storage and transportation, and a soundproof panel using the frame. The frame has a surface that overlaps when stacked.

JP 2006-316444 A

  The frame body for a soundproof panel disclosed in Patent Document 1 prevents deformation at the time of stacking by bringing the upper and lower frames into surface contact when stacked. However, it was not always easy to handle and hold the frame.

  The present invention has been created in view of the above problems, and an object thereof is to provide a frame for a soundproof panel that can be easily handled.

  The frame for a soundproof panel according to the present invention has a columnar portion having a rectangular cross section and a sandwich plate that faces the one surface of the columnar portion substantially in parallel and sandwiches the edge of the soundproof panel main body between the one surface. And the connection part which connects a clamping plate and a columnar part in the outer peripheral side of a frame is provided. In this frame, the outer surface of the connecting portion located on the outer periphery of the frame is located on the outer side of the outer surface of the columnar portion and the outer surface of the connecting portion and the outer surface of the columnar portion form a step. It is characterized by that.

  Since a finger can be hooked on the step formed by the outer surface of the connecting portion and the outer surface of the columnar portion, the user can easily pick up the stacked soundproof panels one by one by using this frame. In particular, the provision of the above steps makes it easier to pick up one by one when the sandwiching plates are stacked up.

  The width of the step is preferably larger than the plate thickness of the columnar part. By having a step having a width larger than the plate thickness, the user can easily hook the finger.

The frame of the present invention preferably further has the following technical features.
The outer frame portion having a substantially U-shaped cross section that opens toward the inner side of the frame body is connected to the side opposite to the one surface of the columnar portion. The outer frame portion extends along the columnar portion.
-The end of the U-shape farther from the columnar part is located outside the frame body than the outer surface of the connecting part.
-When the other frame is stacked on the holding plate side of one frame, the outer frame part of one frame and the outer frame part of the other frame come into contact with each other, and the holding plate of one frame A gap is formed between the columnar part of the other frame.

  The outer frame portion having a U-shaped cross section may be directly connected to the side opposite to the one surface of the columnar portion, or orthogonal to the one surface from the side opposite to the one surface of the columnar portion. You may be connected through the flange extended in the direction to do.

  By providing the above technical features, when the frames are stacked, the outer frame portion of the other frame body is positioned outside the columnar portion of the one frame body.

  One end of a bolt that passes through at least one of the columnar portion and the sandwiching plate and fixes the panel body can be positioned in the gap. By forming a gap, when the frames are stacked, one end of the bolt is sandwiched between the clamping plate of one frame and the columnar part of the other frame, resulting in unstable stacking. To prevent.

  The coupling portion between the sandwiching plate and the connecting portion is curved toward the inside of the frame body, and the columnar portion of the outer frame portion of the other frame body stacked in the space formed by the curvature of the one frame body It is preferable that the end portion of the U-shape on the side close to is located without contacting the coupling portion. A gap formed between the coupling portion and the U-shaped end portion functions as a lateral displacement clearance between the frames stacked vertically.

  The present invention can also be embodied in a soundproof panel in which the above-described soundproof panel frame is attached to a substantially rectangular panel body.

  According to the present invention, it is possible to realize a soundproof panel frame that is easy to handle. In particular, when stacking with the sandwiching plate facing up, it is possible to realize a frame that is easy to pick up one by one from the top.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the soundproof panel 10. The soundproof panel 10 includes a substantially rectangular panel body 12 and a frame body 14 (soundproof panel frame body). The frame body 14 surrounds the outer periphery of the panel body 12. The panel main body 12 and the frame body 14 are screwed at two locations on each side. The broken line shown in FIG. The panel body 12 is made of resin. The frame body 14 is formed by extrusion molding of a metal such as aluminum.

  The frame body 14 will be described in detail. FIG. 2 shows a cross-sectional view of the soundproof panel 10 when viewed along line II-II in FIG. FIG. 3 is a perspective view of the frame body 14. In FIG. 3, reference numerals of some parts are omitted. Refer to FIG. 2 for the reference numerals of the respective parts.

  The frame body 14 retains strength by the columnar part 20 having a rectangular cross section. The right side in FIG. 2 is the outer peripheral side of the frame body 14, and the left side is the inner peripheral side. The four outer peripheral surfaces of the columnar portion 20 are referred to as a first surface 20a, a second surface 20b, a third surface 20c, and a fourth surface 20d, respectively. The second surface 20 b is located on the outer peripheral side of the frame body 14. The fourth surface 20 d is located on the inner peripheral side of the frame body 14.

  The sandwiching plate 22 faces the first surface 20a substantially in parallel. The columnar portion 20 and the sandwiching plate 22 are connected by a connecting portion 24 outside the frame body 14. The panel body 12 is sandwiched between the first surface 20 a of the columnar part 20 and the sandwiching plate 22. A raised portion 22 e is formed on the first surface 22 a, and the raised portion 22 e presses the panel body 12 toward the sandwiching plate 22.

  A connecting portion 26 between the connecting portion 24 and the sandwiching plate 22 is curved toward the inside of the frame body 14.

  In the connection part 24, the surface located in the outer periphery of the frame 14 is called the outer surface 24a. The outer side surface 24a is located outside the frame body 14 from the second surface 20b of the columnar portion 20 (the surface outside the frame body of the columnar portion 20), and the outer surface 24a and the second surface 20b form a step 25. is doing. The size of the step 25 is larger than the plate thickness d of the columnar portion 20.

  A flange 28 is extended from the vicinity of the coupling portion between the second surface 20b and the third surface 20c of the columnar portion 20 in a direction orthogonal to the first surface 20a. An outer frame portion 30 having a substantially U-shaped cross section is connected to the tip of the flange 28. Of the two U-shaped end portions of the outer frame portion 30, the end portion connected to the flange 28 (the end portion closer to the columnar portion 20) is referred to as a proximal end 30 e. The far end is referred to as the distal end 30d. The distal end 30 d is located on the outer side of the frame body 14 with respect to the outer side surface 24 a of the connecting portion 24. As will be described later, when the frame bodies 14 are stacked, the outer frame first surface 30a of one frame body 14 and the outer frame third surface 30c of the other frame body 14 come into contact with each other.

  FIG. 4 shows a cross-sectional view when two soundproof panels 10a and 10b are stacked. The cross-sectional view of FIG. 4 is a cross-sectional view when viewed along line IV-IV of FIG. That is, FIG. 4 shows screws 16 that connect the panel body 12 and the frame body 14. In FIG. 4, reference numerals of some parts are omitted. Refer to FIG. 2 for the reference numerals of the respective parts.

  FIG. 4 shows a state in which the upper soundproof panel 10a is stacked on the holding plate 22 side of the lower soundproof panel 10b. When two soundproof panels are stacked, the outer frame first surface 30a of the lower soundproof panel 10b and the outer frame third surface 30c of the upper soundproof panel 10a are in surface contact. At this time, the sandwiching plate 22 of the lower soundproof panel 10 b and the columnar portion 20 of the upper soundproof panel 10 a face each other with a gap 50 therebetween. A bolt head of the bolt 16 that passes through the columnar portion 20 and fixes the panel main body 12 is located in the gap 50. The gap 50 prevents the bolt 16 of the upper soundproof panel 10a from contacting the lower soundproof panel 10b. As a result, the soundproof panels 10a and 10b do not rattle when stacked. The outer frame first surface 30a is wider than the outer frame third surface 30c.

  A gap 52 is also formed between the coupling portion 26 of the lower soundproof panel 10b and the proximal end 30e of the upper soundproof panel 10a. The gap 52 functions as a horizontal clearance between the upper and lower soundproof panels. That is, the gap 52 prevents the upper and lower soundproof panels from being greatly displaced in the horizontal direction. When the upper and lower soundproof panels are stacked without lateral displacement, the coupling portion 26 of the lower soundproof panel 10b does not contact the proximal end 30e of the upper soundproof panel 10a.

  As shown in FIG. 4, when the soundproof panels 10 are stacked with the sandwiching plate 22 facing upward, the step 25 of the uppermost soundproof panel is exposed. By hooking a finger on the step 25, the uppermost soundproof panel can be easily taken up.

  The columnar portion 20 has a width in the direction parallel to the panel body 12 (width of the first surface 20a and the third surface 20c) perpendicular to the panel body 12 (width of the second surface 20b and the fourth surface 20d). Bigger than. With such a shape, the height of the frame body 14 (the width of the entire frame body 14 in the direction orthogonal to the panel body 12) can be suppressed while maintaining the strength of the frame body 14.

  Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.

  For example, in the soundproof panel of the embodiment, the screw 16 penetrates the columnar portion 20 and fixes the panel body 12. Instead of this, the screw 16 may penetrate the clamping plate 22 and fix the panel body 12. Even in such a case, when the soundproof panels are stacked, one end of the screw 16 is located in the gap 50 between the sandwiching plate 22 and the columnar part 20, so that the same effect as the soundproof panel of the embodiment is achieved.

  The technical elements described in this specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.

The top view of a soundproof panel is shown. Sectional drawing of a frame when it sees along the II-II line | wire of FIG. 1 is shown. It is a perspective view of a frame. Sectional drawing when soundproof panels are stacked is shown.
