Description

  The present invention relates to a soundproof panel and a fence, and more particularly, to noise generated during construction, repair, and demolition work of a building at a construction site, falling of construction members to the outside, or scattering of demolition material. The present invention relates to a soundproof panel used as a temporary enclosure for preventing various influences and damage to surroundings, and a fence using the same.

  Generally, at a construction site and a demolition site, the surroundings of the building are covered with soundproof panels to suppress external effects such as noise caused by the work and scattering of the demolition items. In addition, there is also an effect that the work performed in the building, for example, the spark of the welding work is shielded from the outside. Such soundproofing panels are used for temporary fences surrounding construction sites, and are usually used over and over again.They are used during installation, dismantling, and transportation. Deformation, warping, twisting, breakage, and the like, or deformation and breakage of the panel frame material often occur. When the damage or the like occurs, the panel is used by replacing it with a new panel. Therefore, the soundproof panel in various states is used in a mixed state.

  For this reason, the soundproof panel closes the gap at the side end of the panel so that even if the panels are arranged side by side in the vertical and horizontal directions, the gap between the panels is minimized. Is installed.

  For example, Patent Literature 1 discloses a soundproof panel in which frame members are provided at upper and lower sides and left and right edges of a rectangular panel main body, and packing is fitted into a packing fitting portion that opens outward in the frame member. Have been. Thereby, it is possible to prevent a gap from being formed between the soundproof panels adjacent vertically and horizontally.

JP 09-195518 A

  By the way, in the soundproof panel of Patent Literature 1, the frame member is often provided so as to abut near a corner of the panel body, and the packing is also fitted along the abutted packing fitting portion. The corners are easy to come into contact with the soundproof panel during transportation or construction, and the packing is easily released. In addition, if the packing is merely fitted into the packing fitting portion, if a part of the packing is partially removed, it may be propagated to an adjacent part and the whole packing may be easily removed. For this reason, there has been a demand for a packing that does not easily come off.

  The present invention provides a soundproof panel having a structure in which a packing for closing a gap is difficult to come off.

In order to achieve the above object, the present invention has the following configuration.
That is, a soundproof panel according to the present invention includes a soundproof panel including a rectangular panel body, a frame member attached to an outer peripheral portion of the panel body, and an elastic member attached along a longitudinal direction of the outer peripheral portion of the frame member. A panel, wherein the elastic member includes a flat base, and a protruding portion that protrudes outward from the base, and the frame member includes a storage unit that stores a base of the elastic member. A guide member that is opened outward from the storage portion and has an opening through which the protruding portion can pass is attached, and the elastic member is provided at both ends in a longitudinal direction of the base portion stored in the storage portion. The portion is disposed so as to protrude from both ends in the longitudinal direction of the storage portion, and both ends in the longitudinal direction of the storage portion are crushed to provide a crushed portion.

  In the present invention, the elastic member is arranged so that both ends in the longitudinal direction of the base protrude from both ends in the longitudinal direction of the storage portion, and a protruding portion is formed, and the protruding portion is formed of a frame material. It may be configured not to exceed the longitudinal end.

  According to the present invention, both ends in the longitudinal direction of the elastic member stored in the storage portion are arranged so as to protrude from both ends in the longitudinal direction of the storage portion, and both ends in the longitudinal direction of the storage portion are Since the crushed portion is provided with the crushed portion, even when the crushed portion comes into contact with the vicinity of the crushed portion, a problem that the crushed portion is raised and the elastic member is detached from the storage portion is less likely to occur.

  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 sectional view taken along the line AA in FIG. As shown in FIG. 1, a soundproof panel P according to the present invention includes a rectangular panel body 1, a frame member 2 attached to an outer peripheral portion of the panel body 1, and an elastic member attached to an outer peripheral portion of the frame member 2. 3 is provided.

  The panel main body 1 is formed in a rectangular shape as shown in FIG. In the present embodiment, a metal plate is attached to the upper and lower surfaces of a sheet-shaped core material made of a synthetic resin, and the metal plate, the core material, and the metal plate are laminated in this order and bonded via an adhesive layer, It is preferable because it is lightweight and has excellent sound insulation performance. The thickness of the core material is preferably from 1 to 10 mm, more preferably from 1 to 5 mm, in consideration of moldability, strength, handleability, and the like. The thickness of the metal plate is preferably 0.05 to 1 mm in consideration of weight, workability, handling, and the like.

  The frame member 2 is attached to an outer peripheral portion of the panel main body 1. As shown in FIG. 1, the frame member 2 is continuously attached over the outer peripheral portion of the panel main body 1. As shown in FIG. The frame member 2 is attached to the panel main body 1 by inserting the outer peripheral portion of the panel main body 1 into the groove 21. And it is attached to the whole outer peripheral part of the panel main body 1, and forms a frame.

  In the present embodiment, the frame member 2 is attached along each side of the panel main body 1. At a corner of the panel main body 1, the frame member 2 is partially cut out inside the frame member 2, and It can be folded along. The frame member 2 is not limited to the present embodiment, and is not shown. For example, the frame member 2 is attached to each side of the outer peripheral portion of the panel main body 1, and at the corner of the panel main body 1, A configuration in which the ends in the longitudinal direction are butted together may be used.

  The panel body 1 may be made of an inorganic material such as metal, synthetic resin, wood, paper, cement, or a composite material thereof, and may be provided with a sound absorbing material such as glass wool or rock wool as necessary. It may be something. The frame member 2 may be made of a metal such as an aluminum alloy, a synthetic resin, or a composite material thereof.

  An elastic member 3 is attached to the outer peripheral portion of the frame member 2 along the longitudinal direction. In this embodiment, one of the frame members 2 located on the short side of the panel body 1 is attached along the short side. The elastic member 3 includes a flat base 31 and a protrusion 32 projecting outward from the base 31, and the base 31 is continuously attached along the longitudinal direction of the frame member 2. Accordingly, the protruding portion 32 is provided outside the frame member 2 so as to protrude outside on the opposite side of the panel body 1. The projection 32 may be at least one with respect to the base 31. For example, a plurality of projections 32 may be arranged in the base 31 so as to be separated from each other in the width direction of the base 31. May be provided.

  The elastic member 3 may be made of, 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 in combination. It may be something. Further, as other materials, synthetic rubber or natural rubber may be used alone or in combination. In short, it is preferable to use a material that is easily deformed when stress is applied from the outside such as compression during use, and is easily returned to the original state when the stress is removed.

  FIG. 3 is an enlarged view near the elastic member of FIG. The elastic member 3 is attached to the frame member 2 via a guide member 4 attached to the frame member 2. The guide member 4 includes a storage portion 41 in which the base 31 of the elastic member 3 is stored, and an opening 42 through which the protrusion 32 can pass outward from the base 31 stored in the storage portion 41. , Formed in a long shape.

  The guide member 4 includes a flat bottom 43 fixed to the outer peripheral portion of the frame member 2, a pair of side walls 44, 44 standing up on the same surface of the bottom 43 with a space therebetween, and tips of both side walls 44, 44. And lid portions 45, 45 formed from the portion toward the other end. The storage section 41 is formed by a space surrounded by the bottom section 43, the side wall section 44, and the lid section 45, and a gap provided between the lid sections 45, 45 forms an opening section 42.

  Thereby, when the base 31 of the elastic member 3 is inserted into the storage portion 41 from one end in the longitudinal direction of the guide member 4, the protrusion 32 closes the opening 42 in a state where the base 31 is disposed in the storage portion 41. The elastic member 3 can be attached over the longitudinal direction of the guide member 4 because the elastic member 3 can be projected outward. In this embodiment, the hardness of the base 31 is higher, and the hardness of the protrusion 32 is lower. Accordingly, by increasing the hardness of the base 31, when the base 31 is inserted into the base 31, the base 31 can be easily slid along the longitudinal direction of the storage section 41 without being caught halfway.

  Further, since the hardness of the protruding portion 32 is low, when the gap between the adjacent soundproof panels P is closed, the protrusion 32 is easily deformed so as to close the gap. As described above, by changing the hardness of the base 31 and the protrusion 32, the elastic member 3 can be easily attached, and the workability when the soundproof panel P is arranged can be improved. Further, by applying a lubricant to the surface of the protruding portion 32, when closing the gap, the slidability with the frame material 2 or the like that comes into contact is improved, and the gap can be more easily closed.

  In the present embodiment, the guide member 4 is made of a stainless steel plate by pressing, but may be made of another metal such as an aluminum alloy, a synthetic resin, or a composite material thereof.

  4 is an enlarged plan view of the vicinity of the corner of the soundproof panel of FIG. 1, FIG. 5 is an enlarged side view of the vicinity of the corner of the soundproof panel of FIG. 1, and FIG. 6 is an enlarged sectional view taken along the line BB of FIG. . At the end of the guide member 4 in the longitudinal direction, the crushing portion 46 is crushed so that the distance between the bottom portion 43 and the lid portion 45 is reduced, that is, the crushing portion 46 in which the elastic member 3 is sandwiched between the bottom portion 43 and the lid portion 45. Is provided. Crush portions 46 are provided at both ends in the longitudinal direction of the guide member 4, so that the elastic member 3 can be fixed so as not to come off from the guide member 4.

  Further, the elastic member 3 is provided so as to protrude from an end in the longitudinal direction of the storage portion 41, and a protruding portion 33 is provided. The protruding portions 33 are provided at both ends in the longitudinal direction of the elastic member 3, whereby the crushing portion 46 is located at the end 46 b of the guide member 4 with respect to the longitudinal direction, and Since the whole is not exposed, even when a person or an object comes into contact with the vicinity of the crushed portion 46, deformation such that the space between the bottom 43 and the lid 45 is widened hardly occurs, and the crushed portion 46 is held, The state where the elastic member 3 is hard to be detached from the guide member 4 can be maintained.

  Further, the position Y1 of the end in the longitudinal direction of the guide member 4 is located on the center side from the position Y2 of the end in the longitudinal direction of the frame member 2, and the protruding portion 33 is located between the position Y1 and the position Y2. positioned. This makes it difficult for the soundproof panel P to come into contact with the protruding portion 33 of the guide member 4 when transporting or constructing the soundproof panel P. In particular, in the protruding portion, contact such that the base 31 moves away from the frame member 2 is hard to occur. Therefore, even if they are in contact with each other, the movement of the base 31 is suppressed by the protruding portion 32, so that a stress that causes the crushed portion 46 to spread is less likely to be generated, and the elastic member 3 is less likely to be easily detached from the guide member 4. .

  When the elastic member 3 is broken or deteriorated, the elastic member 3 can be moved in the longitudinal direction of the guide member 4 by opening the crushed portion 46 so as to widen the gap between the bottom 43 and the lid 45. Therefore, the elastic member 3 may be removed from the guide member 4, a new elastic member 3 may be attached to the guide member 4, and the crushing portion 46 may be provided again, so that maintenance is easy.

  In the present embodiment, the end 46 b of the crushed portion 46 is formed to include both ends in the longitudinal direction of the guide member 4, but the end 46 b of the crushed portion 46 is located at an end with respect to the longitudinal direction of the guide member 4. It may be located more centrally.

  FIG. 7 is an enlarged sectional view taken along the line CC of FIG. At both ends of the guide member 4, through holes (not shown) are provided in the bottom portion 43, and are fixed to the frame member 2 via the fasteners 5. In this embodiment, the fasteners 5 are rivets, but bolts and nuts may be used. The head 51 of the rivet as the fastener 5 is arranged on the bottom 43. Thus, the elastic member 3 disposed in the storage section 41 is pressed upward by the head 51. Therefore, in combination with the crushing portion 46, the elastic member 3 is hardly moved in the longitudinal direction of the guide member 4, so that the elastic member 3 can be maintained in a state in which the elastic member 3 is hardly detached from the guide member 4.

  If the positional relationship between the crushed portion 46 and the head 51 is too far, the synergistic effect of the two may be reduced in that the elastic member 3 is hard to come off. Therefore, as shown in FIG. 6, in the crushed portion 46, the head 51 is moved within a distance K between one end 46 a and 46 b in the longitudinal direction of the guide member 4 and the end 46 a and 46 b of the crushed portion 46. Is preferably located at least in part.

  Next, a method for installing the soundproof panel P will be described in detail. 8 and 9 are explanatory diagrams showing a method of installing the soundproof panel. First, a method of arranging the soundproof panels in a vertical direction will be described. As shown in FIG. 8, a mounting member 71 for mounting the soundproof panel P <b> 1 is fixed to the columns 7 erected at predetermined intervals. The attachment 71 has a projecting portion 72 provided in a direction intersecting with the column 7, and a rising portion 73 rising from the projecting portion 72. The rising portion 73 is passed through the mounting hole 22 provided above the frame material 2 of the soundproof panel P1, the frame material 2 is hooked on the rising portion 73, and the soundproof panel P1 is mounted on the mounting fixture 71. Next, another soundproofing panel P2 is moved in the X1 direction and installed above the attached soundproofing panel P1. Subsequently, the rising portion 73 which is moved in the Y3 direction and hooks the frame member 2 of the soundproof panel P1 already attached is passed through the mounting hole 23 provided at the lower portion of the frame member 2 of the soundproof panel P2, The soundproof panel P2 is set on the soundproof panel P1 through the rising portion 73 of the upper mounting tool 71 through the mounting hole 22 of the frame material 2 above the material 2. This operation is repeated, and the soundproof panels P are arranged side by side in the vertical direction. In the present embodiment, since the soundproof panels P are merely stacked and a gap is hardly generated between the frame members 2 of each soundproof panel P, the elastic members 3 are not attached to the upper and lower surfaces of the frame members 2.

  Next, a method of arranging the soundproof panels in a horizontal direction will be described. The elastic member 3 is attached to one of the left and right side surfaces of the frame member 2 of the soundproof panel P. The gap between the soundproof panels P arranged in the left-right direction may be an interval at which the protrusion 32 of the elastic member 3 abuts on the frame 2 of the adjacent soundproof panel P when viewed from the front.

  Since the mounting holes 22 of the frame member 2 are vertically penetrated at both ends of the upper and lower surfaces of the frame member 2 and are formed as long horizontally long holes, it is easy to adjust the gap in the left and right direction between the soundproof panels P. In addition, a gap between the frame members 2 of the adjacent soundproof panels P can be eliminated by the elastic members 3. That is, it is not necessary to attach the elastic member 3 over the entire circumference of the frame member 2, and it is sufficient to attach the elastic member 3 to at least a place where a gap may be generated when the frame member 2 is arranged and installed. In addition, at a place where a gap is generated, as in the present embodiment, a form in which the elastic member 3 is attached to only one of the soundproof panels P may be used. May be.

  As described above, the soundproof panel of the present invention has been described based on the embodiments. However, the present invention is not limited to these embodiments. Various modifications conceived by those skilled in the art without departing from the gist of the present invention are also included in the scope of the present invention.

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