Description

  The present invention relates to a soundproof panel, and more particularly to a soundproof panel fixed by an edge material and a corner piece.

  Scaffolding will be installed on the outer periphery of the building for workers to work and secure passages when constructing, repairing, or building exterior walls. Well done. This soundproof panel plays a role of preventing noise around the site, preventing workers and building materials from falling, and improving the appearance of the construction site.

  In transporting and storing such a soundproof panel, usually, a plurality of soundproof panels are stacked horizontally. However, if the soundproof panels are stacked horizontally, the height at the time of loading becomes high and unstable, and there is a possibility that the cargo collapses and an accident occurs during transportation of a truck or a forklift. Then, the curing net which improves the collapse of the load at the time of loading is proposed (for example, refer to patent documents 1).

  A curing net 70 having a conventional structure, which is a technique similar to that of a soundproof panel, includes a front surface 71 on which a net 75 can be stretched and a side wall 73 provided via a step-shaped refracting portion 72 having a crank-like cross section. Have. When the plurality of curing nets 70 are stacked horizontally as shown in FIG. 5, the surface side of the upper front portion 71 comes into contact with the rear side of the lower refracting portion 72. Therefore, the height when the curing nets 70 are stacked is reduced by the distance from the rear end portion of the side wall portion of the curing net 70 to the rear portion of the refracting portion. Furthermore, there is an advantage that the lateral displacement of the curing net 70 is restricted by the lower side wall portion 73 coming into contact with the upper refracting portion 72.

  However, according to the above means, the area where the upper and lower curing nets come into contact with each other at the time of loading is small, so when the number of the curing nets to be stacked is increased, In addition, the load of all the curing nets is applied intensively, and there is a risk that the frame part may be deformed or damaged. Furthermore, for convenience of transportation and handling, when the frame body frame portion is formed of a light metal material such as aluminum, there is a higher risk of deformation or breakage of the frame portion. Also, depending on how the panel material is attached to the frame part, the frame part is subjected to a torsional load due to its own weight. Therefore, if the cross-sectional structure is like the above-mentioned curing net, the strength of the frame part is low and easily There is a possibility of deformation.

  By the way, at the time of assembling the soundproof panel, in order to fix the panel material and the frame portion, for example, attachment is performed from the rear surface side of the panel material using an attachment tool such as a tapping screw. For this reason, the tip of the attached tapping screw is exposed from the front part of the soundproof panel, and there is a risk that the field worker or the like may be injured.

In addition, since it is necessary to fit the panel material into the frame portion and fix it using a fixture and to fix the corner portion by welding or the like, the soundproof panel assembling work is extremely complicated.

As shown in FIG. 3, the outer frame portion 56 is formed, and a bent portion 57 is formed on the inner peripheral side at the rear end portion of the outer frame portion 56 as defined in the invention of claim 3. Even when some severe impact is applied when the soundproof panels 10 are stacked, lateral movement is restricted by the outer frame portion 56 or the bent portion 57, and load collapse can be prevented. Further, the bent portion 57 may be provided so as to come into contact with the upper protruding portion 55 when the soundproof panels 10 are stacked. In this case, the load from the upper portion is applied to the bent portion 57 and the above-described mounting portion. Since it can disperse | distribute to the groove part 46 and a load is not applied locally, the sound-insulation panel 10 becomes difficult to deform | transform. In addition, since the overhang portion 55 and the bent portion 57 are more likely to be loaded than other portions, if the wall thickness is increased, the soundproof panel 10 becomes more difficult to deform and the durability is improved. .

  Next, a method for enforcing the soundproof panel 10 as described above on a scaffold or the like will be described. First, as described above, the four edges Pe of the panel material P are fitted into the edge material 20, respectively, and fixed by the corner piece 50 at the corner portion C of the edge material, and as shown in FIG. The A support bolt B provided on a scaffolding column or the like is inserted into a through hole 58 formed in the outer frame portion 56 of the corner piece 50. The support bolt B is inserted into the through hole 58 of another soundproof panel 10 in the upper part of the soundproof panel 10 through which the bolt B is inserted. Since the outer frame portion 56 of the lower soundproof panel 10 and the outer frame portion 56 of the upper soundproof panel 10 are in pressure contact with each other due to their own weight, noise on the construction site is blocked. Similarly, as shown in FIG. 4, the soundproof panel 10 is attached to the outer periphery of the scaffold in the vertical and horizontal directions.

  Further, if the outer peripheral plate portion 44 of the edge member 20 is provided with, for example, elastic stacking such as rubber, the outer frame portion 56 is in pressure contact with the soundproof panel frame body when it is applied to the scaffold, and stacking is also performed. Since it is pressed and pressed, it is expected that the noise blocking effect can be further enhanced. Moreover, the noise at the time of a frame body contacting can also be reduced at the time of the installation construction to the scaffold of the sound-insulation panel 10, or the conveyance in a loading state.
