Description

  The present invention relates to a soundproof panel and a fence, and more specifically, noise generated during construction, repair, and demolition of a building at a construction site, dropping of a construction member to the outside, or scattering of a demolition The present invention relates to a soundproof panel used for temporary enclosure to prevent various influences and damages on the surroundings, and a bag using the soundproof panel.

  In general, at the construction work site and the demolition work site, the surroundings of the building are covered with a soundproof panel to suppress external influences such as noise accompanying the work and scattering of the demolished material. In addition, there is an effect of blocking work performed in the building, for example, sparks of welding work from being seen from the outside. Such soundproof panels are used for temporary fences surrounding the construction civil engineering site and are usually used over and over again, and the entire panel is being used, installed and dismantled, and transported. In many cases, deformation, warping, twisting, or breakage of the panel frame material or deformation or breakage of the panel frame material occurs. When a damage or the like occurs, a new panel is used for replacement. Therefore, the soundproof panel in various states is used in a mixed state.

  For these reasons, the soundproofing panel closes the gaps at the side edges of the panels so that gaps do not occur as much as possible even when the panels are installed side by side in the vertical and horizontal directions. For this purpose, a member such as a so-called packing is attached.

  For example, the cited document 1 discloses a soundproof panel in which frame members are provided on the upper and lower and left and right edges of a rectangular panel body, and packing is fitted in a packing fitting portion that opens outward in the frame member. Has been. Thereby, it can prevent that a clearance gap produces between the soundproof panels adjacent on the upper and lower sides and right and left.

JP 09-195518 A

  By the way, in the soundproof panel of Patent Document 1, the frame member is often abutted and provided near the corner of the panel body, and the packing is also fitted along the abutting portion of the packing. The corners are easy to come in contact with when transporting or constructing the soundproof panel, and the packing is easy to come off. Further, if a part that is partially detached is generated only by inserting the packing into the packing insertion part, it may be propagated to the next side and the whole packing may be easily detached. In the field, since the soundproof panels in various states are mixed, there is a need for a packing that is easy to install and difficult to come off.

  The present invention provides a soundproof panel having a structure in which an elastic member such as packing for closing a gap is easily attached and is not easily detached.

In order to achieve the above object, the present invention is configured as follows.
That is, the soundproof panel according to the present invention includes a rectangular panel main body, a frame member attached to the outer peripheral portion of the panel main body, and an elastic member attached along the longitudinal direction of the outer peripheral portion of the frame member. The elastic member has a base portion having a facing surface facing the outer peripheral portion of the frame member, and two projecting portions provided at intervals in the width direction along the longitudinal direction from the base portion. The frame member includes a storage groove portion in which the projecting portion is stored and arranged in parallel along the longitudinal direction of the frame member, and the opposing surface of the base portion is upward from both ends in the width direction toward the center portion. And a gap is formed between a top portion where the inclined surfaces meet each other and an outer peripheral surface of the frame member.

  Moreover, the scissors according to the present invention are scissors formed using the soundproof panel, and the elastic member of the soundproof panel is formed from the base toward the outside of the soundproof panel and has a hollow inside. The soundproof panels are arranged side by side, and in the adjacent soundproof panels, the hollow portions of the respective elastic members are pressed against each other.

  Further, in the soundproof panel according to the present invention, the protrusions have flanges protruding in a direction approaching each other, and the storage groove engages with the flange and moves the protrusion toward the opening side. You may make it have the receiving part which blocks | prevents.

  Furthermore, in the soundproof panel according to the present invention, the elastic member may be attached to two sides constituting the corner portion of the frame member.

  According to the soundproof panel according to the present invention, the frame member includes a storage groove in which the protruding portion of the elastic member is stored and arranged in parallel along the longitudinal direction of the frame member, and the opposing surface of the base portion of the elastic member is Since there is an inclined surface that inclines upward from both ends in the width direction toward the center portion, and a gap is formed between the top portion where the inclined surfaces meet each other and the outer peripheral surface of the frame member, the elastic member is framed When attaching to the material, if the operator presses the top of the opposing surface of the base toward the outer peripheral surface of the frame material, the protrusions are pushed apart in a direction away from each other, so that the protrusions can be easily inserted into the storage grooves. After the insertion, if the operator removes his hand from the elastic member, the top part will move away from the outer peripheral surface and the projecting parts will move closer to each other. If so, the elastic member can be reliably attached to the frame member. Furthermore, if the elastic member is damaged during installation, the elastic member can be easily removed by pressing the top of the opposing surface of the base against the frame material side, so that the replacement work can be performed smoothly.

  According to the bag according to the present invention, since the elastic member of the soundproof panel has a hollow portion formed from the base portion toward the outside of the soundproof panel and having a hollow inside, the soundproof panel is arranged in parallel. In this case, the gap between the soundproof panels is closed by arranging the hollow parts so as to be pressed against each other, and the top part of the base part is not directly contacted by the hollow, so that the elastic member is prevented from being easily detached. be able to.

  In the soundproof panel according to the present invention, the protrusions may have protrusions protruding in a direction approaching each other, and the storage groove may have a receiving part that prevents the protrusion from moving toward the opening side. If the elastic member is attached to the frame material, if the top of the base is pressed against the frame material, the protrusions of the protrusions move away from each other and hardly interfere with the receiving part. Thereafter, the protrusion can be reliably engaged with the receiving portion.

  Further, in the soundproof panel according to the present invention, when the elastic member is attached to each of two sides constituting the corner portion of the frame member, when the soundproof panel is arranged in the vertical direction and the horizontal direction, the adjacent soundproof panel Since an elastic member will be arrange | positioned between these, the clearance gap between soundproof panels can be made hard to produce.

Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.
FIG. 1 is a schematic perspective view showing an embodiment of a soundproof panel according to the present invention, and FIG. 2 is an enlarged cross-sectional view taken along line AA in FIG. As shown in FIG. 1, the soundproof panel P according to the present invention includes a rectangular panel main body 10, a frame member 20 attached to the outer peripheral portion of the panel main body 10, and the longitudinal direction of the outer peripheral portion of the frame member 20. And an attached elastic member 30.

  In this embodiment, the panel main body 10 is formed by attaching metal plates on the upper and lower surfaces of a synthetic resin sheet-like core material, and laminating the metal plate, the core material, and the metal plate in this order and bonding them through an adhesive layer. It is a laminate and is preferable because it is lightweight and has excellent sound insulation performance. The thickness of the core material is preferably 1 to 10 mm, more preferably 1 to 5 mm in consideration of moldability, strength, handleability, and the like. In addition, the thickness of the metal plate is preferably 0.05 to 1 mm in consideration of weight, workability, handling, and the like.

  The panel body 10 may be made of an inorganic material such as metal, synthetic resin, wood, paper, cement, or a composite material thereof, and is provided with a sound absorbing material such as glass wool or rock wool as necessary. It may be a thing.

  The frame member 20 is continuously attached over the outer periphery of the panel body 10. As shown in FIG. 2, the frame member 20 is provided with a groove portion 21 that opens to the inside. By inserting the outer peripheral portion of the panel body 10 into the groove portion 21, the frame member 20 is attached to the panel body 10. It is done. And the frame material 20 is attached to the whole outer peripheral part of the panel main body 10, and forms the rectangular frame. The frame member 20 may be made of a metal such as an aluminum alloy, a synthetic resin, or a composite material thereof.

  In this embodiment, the frame member 20 is attached along each side of the panel main body 10, and at the corners of the panel main body 10, the inside of the frame member 20 is partially cut out along the corners. Can be bent. The frame member 20 is not limited to the present embodiment and is not shown. For example, the frame member 20 is attached to each side of the outer peripheral portion of the panel body 10, and the corner member of the panel body 10 A configuration in which end portions in the longitudinal direction are abutted with each other may be used.

  As shown in FIG. 1, the elastic member 30 is attached along the longitudinal direction of the frame member 20 located on the short side of the panel body 10 in this embodiment. The elastic member 30 may be prepared from, for example, a thermoplastic elastomer. Specifically, a styrene-based elastomer, an olefin-based elastomer, a vinyl chloride-based elastomer, or the like may be used alone, or these may be used in combination. It may be what was. Furthermore, synthetic rubber or natural rubber may be used alone or in combination as other materials. In short, it is preferable to use a material that is easily deformed when stress is applied from the outside, such as compression, and can easily return to the original state when the stress is removed.

  FIG. 3 is an enlarged cross-sectional view of the elastic member shown in FIG. The elastic member 30 includes a base portion 32 having a facing surface 31 that faces the frame member 20, and two projecting portions 33 that are spaced from the base portion 32 in the width direction along the longitudinal direction. Furthermore, the elastic member 30 has a hollow portion 34 formed in a direction away from the frame member 20 and having a hollow inside. That is, the elastic member 30 has a protruding portion 33 that protrudes toward the center portion side of the panel body 10 with the base portion 32 interposed therebetween, and a hollow portion 34 formed on the opposite side.

  The facing surface 31 of the base portion 32 has inclined surfaces 31a and 31b that are inclined upward from both ends in the width direction toward the central portion, and a top portion 35 where the inclined surfaces 31a and 31b meet each other. Thereby, when the elastic member 30 is attached to the frame member 20, a gap S1 is formed between the facing surface 31 and the frame member 20 as shown in FIG.

  In this embodiment, the inclined surfaces 31a and 31b are formed in a circular arc shape that protrudes in a direction away from the frame member 20 from one width direction end portion of the opposing surface 31 to the other width direction end portion. The vicinity of the arcuate apex is the apex 35. For example, the inclined surfaces 31a and 31b may be formed on a flat surface to have a vertical cross-sectional shape, and the corner may be the apex.

  In this embodiment, the protruding portion 33 includes a flange portion 36 that protrudes toward the opposing surfaces. More specifically, the flange portion 36 has a tapered shape and has a slope 37 formed from the tip portion to the upper end portion. It is recessed from the upper end of the inclined surface 37 toward the protruding portion 33, and has a recessed portion 38 between the opposing surface 31.

  The hollow portion 34 has a covering portion 34a that covers the hollow above the base portion 32, and in this embodiment, the hollow portion 34 is formed in a longitudinal arc shape. Then, both end portions of the covering portion 34a are connected to the upper surface side of the base portion 32 to form a connecting portion 34b.

  FIG. 4 is a partially enlarged cross-sectional view of the frame member, showing a place where the elastic member is attached. The frame member 20 includes two storage groove portions 22 in which the two protrusions 33 of the elastic member 30 are respectively stored. The storage groove portion 22 has a receiving portion 23 that protrudes from the side wall portion on the side close to each other toward the opposite side wall portion. The receiving part 23 is formed in the upper part of the side wall part, and the upper part side of the protrusion tip is provided with a guide part 24 having an inclined surface that inclines so that the groove width of the storage groove part 22 widens upward. As a result, the opening width of the storage groove portion 22 is narrowed downward from the opening, and in the lower side of the lower end of the receiving portion 23, the storage groove portion 22 has a vertical dovetail shape in which the groove width increases toward the side wall portion on the receiving portion 23 side. Is formed. In this embodiment, the upper end of the storage groove portion 22 where the guide portion 24 is formed has a guide portion 24 and the lower portion of the storage groove portion 22 has the same groove width. In addition, since the inclined surface of the guide part 24 should just be formed so that the protrusion part 33 of the elastic member 30 may be easily inserted in the back of the storage groove part 22, even if it makes the protrusion front end side of the receiving part 23 into an inclined surface over the whole region Good.

  Next, a procedure for attaching the elastic member 30 to the frame member 20 will be described in detail with reference to FIGS. FIG. 5 shows a state in which the elastic member is brought into contact with the frame member, FIG. 6 shows a state in which the protruding portion of the elastic member is being pushed into the storage groove portion of the frame member, and FIG. FIG. 7B shows a state in which the flange portion of the protruding portion and the receiving portion of the storage groove portion are engaged.

  First, as shown in FIG. 5, the two protruding portions 33 of the elastic member 30 are brought close to the storage groove portion 22. At this time, the inclined surface 37 of the protruding portion 33 and the guide portion 24 of the receiving portion 23 of the storage groove portion 22 come into contact with each other. It is to be noted that the distance S2 of the narrowest portion between the flange portions 36, 36 of the projecting portions 33, 33 is the distance S2 between the upper ends of the inclined surfaces 37 in this embodiment, and the distance S3 of the widest portion between the guide portions 24. Since it is narrower, the protrusion 33 does not advance to the back of the storage groove 22 simply by placing the elastic member 30 on the frame member 20.

  Subsequently, when the elastic member 30 is pressed toward the frame member 20, as shown in FIG. 6, the flange portion 36 of the protruding portion 33 moves downward along the guide portion 24. The protruding portion 33 moves toward the inner side of the storage groove portion 22 while being urged toward the receiving portion 23 side. At this time, since the elastic member 30 including the base portion 32 is elastically deformable, the base portion 32 is subjected to a stress that is spread laterally and a force that the top portion 35 of the opposing surface 31 protrudes relatively downward. work.

  That is, the elastic member 30 can be moved to the frame member 20 side until the vicinity of the top portion 35 abuts on the frame member 20, but the vicinity of the top portion 35 is in addition to the downward movement of the elastic member 30, as described above. Due to the downward projecting force, the movable distance of the top 35 becomes relatively short. On the other hand, since the opposing surface 31 protrudes in a direction away from the frame member 20, the distance that can be moved from the vicinity of the top 35 to the frame member 20 side is longer than when the opposing surface 31 is planar. The projecting portion 33 can be pushed further into the storage groove portion 22. In addition, if the stress by which the base portion 32 is pulled in the lateral direction becomes too large, the distal end side of the protruding portion 33 becomes difficult to expand further, but the facing surface 31 of the base portion 32 is deformed so as to approach a straight line from an arc shape. Thus, since the dimension of the base 32 on the side of the facing surface 31 can be extended in the lateral direction, the protrusion 33 can be easily moved toward the back of the storage groove 22.

  Further, when the elastic member 30 is pressed toward the frame member 20 and the upper end portion of the inclined surface 37 of the projecting portion 33 reaches the back side from the lower end portion of the receiving portion 23 of the storage groove portion 22, FIG. As shown, the urging of the projecting portion 33 toward the receiving portion 23 side is released, and the flange portion 36 moves in the Q direction below the receiving portion 23. At the same time, at least a part of the receiving portion 23 is R It moves into the recess 38 which is the direction. Then, as shown in FIG. 7B, the stress such as the tension acting on the base portion 32 is also released, and the vicinity of the top portion 35 of the facing surface 31 moves to the direction away from the frame member 20.

  Thereby, the elastic member 30 is attached to the frame member 20. The protrusion 33 is prevented from moving to the opening side of the storage groove 22 by engaging the flange portion 36 and the receiving portion 23, and can firmly fix the elastic member 30 to the frame member 20.

  Further, although the opposing surface 31 of the base portion 32 of the elastic member 30 is separated from the frame material 20 in the vicinity of the top portion 35, the vicinity of both end portions does not move in the direction away from the frame material 20 as much as the top portion 35. 20 is relatively close. That is, since the elastic member 30 protrudes in a circular arc shape with the opposing surface 31 having the apex of the vicinity of the apex 35, when attaching to the frame member 20, the protrusion 33 is moved deeper than the storage groove 22. After the attachment to the frame member 20, the vicinity of both end portions of the opposing surface 31 is close to the frame member 20, and coupled with the engagement between the flange portion 36 and the receiving portion 23, After the engagement, the movement of the opposing surface 31 of the elastic member 30 moving away from or approaching the frame member 20 can be suppressed.

  Next, the installation method of the bag F using the soundproof panel P will be described in detail. FIG. 8 and FIG. 9 are explanatory views showing a method for installing a bag using a soundproof panel. First, a method for arranging the soundproof panels P1 and P2 in the vertical direction will be described. As shown in FIG. 8, the fixture 41 for attaching the soundproof panel P1 is being fixed to the support | pillar 40 standingly arranged by the predetermined space | interval. The fixture 41 has a protruding portion 42 provided in a direction intersecting with the support column 40, and a rising portion 43 that rises from the protruding portion 42. The rising portion 43 is passed through the mounting hole 25 provided in the upper portion of the frame member 20 of the soundproof panel P1, and the frame member 20 is hooked on the rising portion 43 to attach the soundproof panel P1 to the fixture 41. Next, another soundproof panel P2 is moved in the X direction and installed above the soundproof panel P1 attached. Subsequently, the rising portion 43 that moves in the Y direction and hooks the frame member 20 of the soundproof panel P1 that has already been attached is passed through the mounting hole 26 provided in the lower portion of the frame member 20 of the soundproof panel P2, and the frame The soundproof panel P2 is installed on the soundproof panel P1 through the rising portion 43 of the upper fixture 41 through the mounting hole 25 of the upper frame material 20 of the material 20. By repeating this work, the soundproof panels P are arranged side by side in the vertical direction. In this embodiment, since the sound insulation panels P are simply stacked and no gaps are formed between the frame members 20 of the sound insulation panels P, the elastic members 30 are not attached to the upper and lower surfaces of the frame members 20. The member 30 may be attached.

  Next, a method for installing soundproof panels side by side in the left-right direction will be described. As shown in FIG. 9, the soundproof panel P has elastic members 30 attached to the left and right side surfaces of the frame member 20. The gap between the soundproof panels P arranged in the left-right direction may be an interval at which the hollow portions 34 of the elastic member 30 are in contact with each other in a front view, preferably an interval at which the hollow portions 34 are pressed against each other. When the hollow portions 34 are pressed against each other, if the degree of pressing is large, the top portion 35 of the facing surface 31 of the base portion 32 moves to the frame member 20 side and deforms in a direction in which the interval between the protruding portions 33 increases. The elastic member 30 may be easily detached from the frame material 20. Therefore, the degree of pressing is preferably such that a hollow remains between the covering portion 34a and the base portion 32 of the contacting hollow portion 34.

  Since the mounting holes 25 of the frame member 20 are vertically penetrated at both end portions of the upper and lower surfaces of the frame member 20 and are formed as horizontally elongated holes in the left-right direction, it is easy to adjust the left-right gap between the soundproof panels P. The gap between the frame members 20 of the adjacent soundproof panels P can be eliminated by the elastic member 30. In other words, the elastic member 30 does not have to be attached over the entire circumference of the frame member 20, and may be attached at least at a place where a gap may be generated when the frame member 20 is installed side by side. Moreover, in the location where a clearance gap arises, the form which attached the elastic member 30 to the both sides of the short side of the soundproof panel P may be sufficient like this form.

  Moreover, as shown in FIG. 10, the form which attached the elastic member 30 only to one side of the short side of the soundproof panel P may be sufficient. In addition, the state installed side by side in the left-right direction using the soundproof panel P shown in FIG. 10 is shown in FIG. Thus, the elastic member 30 is attached to only one side of the adjacent short sides of the soundproof panels P adjacent to the left and right, and the elastic member 30 is disposed on the short side of the soundproof panel P to which the elastic member 30 is not attached. By abutting or pressing, the soundproof panels P can be installed without gaps.

  FIG. 12 is a schematic perspective view showing still another embodiment of the soundproof panel according to the present invention, and FIG. 13 is an enlarged cross-sectional view of a main part near the through hole of the elastic member. In this embodiment, the elastic member 30 is attached to one short side and one long side of the soundproof panel P. That is, if the frame member 20 of the soundproof panel P has the storage groove 22 to which the elastic member 30 is attached over the entire circumference, the elastic member 30 is provided on both the long side and the short side of the soundproof panel P. Can be installed.

  When the elastic member 30 is attached to the long side of the soundproof panel P, the upright portion 43 of the fixture 41 is allowed to pass in the vertical direction so as not to block the attachment hole 25 of the frame member 20 to which the elastic member 30 is attached. It is preferable to provide a through hole 39 that permits and communicates with the mounting hole 25. Further, the size of the through hole 39 is preferably about the same as or larger than that of the mounting hole 25. In addition, when attaching the elastic member 30 to the frame member 20 side provided with the attachment hole 26, the through-hole 39 may be provided in the elastic member 30 in accordance with the position and size of the attachment hole 26.

  As a result, when the soundproof panels are arranged in the vertical direction and the left-right direction to form the collar, the elastic member is disposed between the adjacent soundproof panels, so that it is difficult to generate a gap between the soundproof panels. it can. Therefore, the noise generated by the work is less likely to leak to the outside from the bag made using the soundproof panel.

  As mentioned above, although the soundproof panel of this invention was demonstrated based on embodiment, this invention is not limited to these embodiment. The present invention includes various modifications made by those skilled in the art without departing from the scope of the present invention.

  INDUSTRIAL APPLICABILITY The present invention can be widely used as a soundproof panel that covers the surroundings of construction and civil engineering sites such as a construction site and a demolition site, and can be disassembled and used at another site after the work is completed.
