[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is mainly provided on a building construction site on the outer surface of a temporary structure such as a steel pipe scaffold to prevent the transmission of construction noise to the outside and to prevent building materials such as bolts from falling to the outside. The present invention relates to a soundproof panel used for performing soundproofing.
[0002]
[Prior art]
As a soundproofing panel used to surround the surroundings of construction sites where buildings are constructed or dismantled, a panel made of a sound-absorbing material, a sound-absorbing plate, a sound-insulating plate, etc. Those whose front and back are covered with aluminum plate or steel plate are widely used. However, soundproofing panels using the above panel materials and the like are inexpensive and durable, but uniform, unsuitable for the surrounding environment, and dark in the construction site because they do not pass light, There was a problem of giving a closed impression.
[0003]
The applicant of the present application has previously proposed a temporary panel using a synthetic resin flat plate having a light-transmitting property such as a polycarbonate resin (see Japanese Patent Application No. 8-326012).
[0004]
[Problems to be solved by the invention]
However, the temporary panel using this translucent synthetic resin plate should be installed at a height of about 2 to 3 m above the ground, and light should be taken into the interior of the construction site, etc., partitioned by the temporary panel to make it brighter. Although it has the advantage of being able to wipe out the closed impression of construction sites, etc., the rigidity of the synthetic resin plate itself is low and it is easily deformed by wind pressure etc., so it should be used as a panel used at high places Could not. Also, depending on the application, a frame member separate from the synthetic resin plate can be provided around the synthetic resin plate to reinforce it, but in this case, the weight of the temporary panel increases and the manufacturing cost increases. Had the problem of rising. In particular, when a metal member such as aluminum is used for the frame member, the thermal expansion coefficient of the synthetic resin flat plate is different from that of the frame member. There was a problem that it was distorted or damaged. Further, since the temporary panel has low sound insulation performance, it cannot be used in a construction site or the like where a loud noise is generated.

The effect is eliminated, and the panel body is distorted due to the difference between expansion and contraction due to temperature change, thereby eliminating the possibility of deformation.
A metal frame member separate from the panel body is disposed at both end edges forming a right angle to the projection so as to cover the edge, and the upper and lower ends of the frame member are fixed to the frame of the panel body. The soundproof panel is fixed to the temporary structure or a through hole for connecting the soundproof panels is formed in the same position in the frame and frame member of the panel body. By doing so , the load on the soundproof panel can be supported by the frame member, the rigidity of the soundproof panel can be further improved, and the soundproof panel can be easily fixed to the frame of the panel body, and the soundproof panel can be easily suspended. it can.
Further, by disposing the frame member, the cut end surface of the panel main body is not exposed, there is no risk of injuring a person, and the work can be performed safely during transportation and construction.
Further , even if a metal member such as aluminum having a different coefficient of thermal expansion from that of the panel body made of a synthetic resin plate is used for the frame member, the difference in expansion and contraction of the soundproof panel due to a temperature change at the band-shaped protrusion is reduced. It can be absorbed and can prevent the soundproof panel from being deformed, distorted, or damaged.

The synthetic resin plate has a light-transmitting property, and a transparent one or a translucent one such as a matt can be used. Accordingly, light can be taken into the interior of the construction site or the like partitioned by the soundproof panel P to make it brighter, and a closed impression of the construction site or the like can be wiped out. In particular, a transparent synthetic resin plate is used. When used, safety is improved because the field of view is widened.
[0011]
In this case, the plate thickness t of the panel main body 1 is preferably formed to be 3.5 to 6.0 mm, more preferably 3.7 to 5.0 mm.
If the thickness t of the panel body 1 is smaller than 3.5 mm, it becomes difficult to obtain the required rigidity and sound insulation performance, whereas if it is larger than 6.0 mm, the weight increases and the manufacturing cost increases.
[0012]
In addition, the angle θ between the flat portion 11a and the slope portion 11b of the protrusion 11 is preferably formed to be 100 to 130 °.
If the angle θ between the flat portion 11a and the inclined portion 11b of the protrusion 11 is smaller than 100 °, it is difficult to form the protrusion 11, and if it is larger than 130 °, it is difficult to obtain required rigidity.
[0013]
The height H of the projection 11 is preferably set to 35 to 60 mm.
If the height H of the protrusion 11 is smaller than 35 mm, it becomes difficult to obtain the required rigidity, and if it is larger than 60 mm, the weight increases and the manufacturing cost increases.
[0014]
The width W of the flat portion 11a of the projection 11 is preferably 50 to 120 mm, more preferably 90 to 110 mm.
If the width W of the flat portion 11a of the protrusion 11 is smaller than 50 mm, it is difficult to form the protrusion 11, and if it is larger than 120 mm, it is difficult to obtain required rigidity.
[0015]
The interval D between the adjacent protrusions 11 is preferably set to 50 to 120 mm, more preferably 90 to 110 mm.
If the distance D between the adjacent protrusions 11 is smaller than 50 mm, it is difficult to form the protrusions 11. If the distance D is larger than 120 mm, it becomes difficult to obtain the required rigidity.
[0016]
The frame member 2 is desirably configured to have a strength capable of supporting the weight of the soundproof panel P. In this embodiment, the frame member 2 is formed in a U-shaped cross section, and the frame portions 12 and The upper and lower ends of the soundproof panel P are bent inward so that the soundproof panel P can be easily fixed to the panel 12 and suspended.

Further , even when a metal member such as aluminum having a different coefficient of thermal expansion from the panel body 1 made of a synthetic resin plate such as a polycarbonate resin is used for the frame member 2, as shown in FIG. When the angle θ between the flat portion 11a of the protrusion 11 and the slope 11b changes from θ0 to θ1 or θ0 to θ2, or vice versa, the flat portion 11a of the protrusion 11 By adding the portion 11b to the width, W0 to W1 or W0 to W2 or vice versa, the difference in expansion and contraction of the soundproof panel P due to a temperature change can be absorbed, and the soundproof panel P deforms, Distortion or damage can be prevented.
[0017]
Moreover, since the frame parts 12 and 12 formed by bending the edges parallel to the projections 11 of the panel main body 1 are made of the same material as the panel main body 1, the weight of the soundproof panel P can be reduced. In addition, the influence of expansion and contraction of the soundproof panel P due to a temperature change can be eliminated, the durability can be improved, and the rigidity can be improved and the bending can be eliminated. Incidentally, from the viewpoint of rigidity only, a metal member may be used.However, a difference in expansion and contraction due to a temperature change may cause distortion and deformation of the panel body. The frame formed at the edge in the side (lateral) direction is made of the same material as the panel body 1.
Further, the cut end surface of the panel main body 1 is not exposed by the frame portion 12 and there is no risk of injuring a person, so that the work can be safely performed during transportation and construction.
Furthermore, since the frame portion 12 can be formed by simply bending the panel main body 1 and there is no need to use other members, the production cost of the soundproof panel P can be reduced and the rigidity of the panel main body 1 can be reduced. As a result, even if a polycarbonate resin plate having a small thickness is used, no problem is caused, and as a result, material costs can be reduced.
[0018]
Such a panel body 1 can be manufactured by bending a synthetic resin plate such as a polycarbonate resin, but can also be manufactured by extrusion molding.
[0019]
In the frame portions 12, 12 and the frame member 2 of the panel body 1, through holes 13 for fixing the soundproof panel P to a temporary structure such as a frame or a support or connecting the soundproof panels P to each other at an arbitrary position. , 21 are drilled at the same position.
