JP3886990B2 - Electromagnetic shield partition, and panel material and edge member for the partition - Google Patents

Description

  The present invention relates to an electromagnetic shield partition, a panel material for the partition, and an edge member.

  In recent years, problems such as interference from wireless microphones in conference rooms in office buildings, noise contamination due to outdoor electromagnetic noise, malfunctions of electronic devices, information leakage due to radio waves, etc. have occurred, and the frequency of local wireless telephones such as PHS has been effectively used. Therefore, it is desired to divide the campus. In order to deal with these problems, there is a need for a partition with electromagnetic shielding in the building.

  Such an electromagnetic shielding partition is generally subjected to electromagnetic shielding treatment on both the front and back sides of the panel material. Because this type of partition is often required to have multiple functions such as sound insulation and fire resistance in addition to electromagnetic shielding, and in order to realize these other functions, This is because if a sound insulating material or a fireproof material is used for the core material or the like, the electromagnetic shielding performance must be ensured only by the outer surface portion of the panel. However, for example, when a plurality of panel materials are joined together to form an electromagnetic shield partition, there is a gap in a part of the joints due to irregular dimensions of the panel materials and insufficient joining work. The electromagnetic wave cannot be completely blocked. Therefore, various attempts have been proposed mainly to shield the joint portion of the panel.

  In Patent Document 1, a prismatic connecting material is sandwiched between end faces of adjacent electromagnetic shielding panel materials, and electromagnetic shielding extended from the panel material surface in a longitudinal groove provided in the middle of the surface thickness direction of the connecting material. The plate is folded and a conductive tape is stuck between the opposite ends of the extension plate portion.

  The thing of patent document 2 fits the fitting convex part and fitting concave part of the corresponding shape which were provided in the opposing side end surface of the panel material of 2 sheets which sticks a metal plate on the surface of a radio wave absorptive core material. The conductive packing is housed in the recess.

  In Patent Document 3, the left and right side portions of the connecting plate member are fixedly fitted in the longitudinal groove formed in the middle portion in the thickness direction of the opposite end portion of the electromagnetic shielding panel material that contacts the side edge, and the opposite end portion of the opposite end portion is fixed. A conductive elastic member is inserted between the front side portion and the back side portion.

The thing of patent document 4 is an electromagnetic shielding structure of the junction part of a column and two panels, and it folds back so that an electromagnetic shielding board may not contact mutually from the front and back both surfaces of both panel materials, and both The front and back sides of the joint of the panel material are sandwiched between a pair of electrically conductive and wide pair of pillar members, and each half is fastened with a bolt.

  The thing of patent document 1 cannot anticipate the electromagnetic shielding performance over a long period of time, since there exists a possibility that the electroconductive tape adhere | attached on the opposing edge part of an electromagnetic shielding board may peel off.

  In Patent Document 2 and Patent Document 3, a gap that may occur in a part of the joint portion due to dimensional irregularities of the uneven fitting portion of the panel material is closed with a conductive elastic material. If a gap is created between the two panels due to an earthquake or other vibration, leakage of electromagnetic waves cannot be prevented.

  In Patent Document 4, since the joint portions of both panel members are sandwiched between the wide column member halves, the shielding effect is high, but the shield portion formed by both halves protrudes greatly from the panel outline. That is, it is not suitable for a panel joint shield structure other than the column installation location.

  Therefore, in view of the above-mentioned problems of the prior art, the present invention provides an adjacent partition forming main member in order to obtain an electromagnetic shielding effect as well as an excellent appearance and, more preferably, a partition having an excellent sound insulation effect. From the opposing end of the electromagnetic shielding surface portion, the first and second engaging strips having a bowl-shaped cross section are formed.

A pair of front and back electromagnetic shielding plates 6, 6 are attached to the outer surfaces of the sound insulating plates 8, 8, and the outer surfaces of these electromagnetic shielding plates 6 are used as the electromagnetic shielding surfaces 4.

  In the illustrated example, as shown in FIGS. 5 and 1, the upper surface of the upper blocking plate 14 is disposed slightly below the upper end surfaces of the sound insulating plates 8, 8, and the upper end portion inner surfaces of the sound insulating plates 8, 8 are A concave groove 18 for inserting a ceiling side support means (runner), which will be described later, is formed on the upper surface of the closing plate 14. The electromagnetic shielding plates 6 and 6 on both the front and back sides are folded back to the concave grooves 18 and 18 from the upper end surfaces of the sound insulating plates 8 and 8.

  Further, also on the end surface of the adjacent panel member 2A facing the wall surface of the room, the side outer surface of the end member 12 is positioned closer to the inner side of the panel member 2A than the side end surfaces of the sound insulating plates 8 and 8, as shown in FIG. Thus, a concave groove 18 is formed by the inner surfaces of the sound insulating plate side end portions and the end member 12 side end surface.

  The joint shield structure between the panel materials and the shield structure at the connection portion between the panel material and the floor side, the ceiling side, and the wall side will be described later.

The folded plate portion 6a is provided so as to be electrically connected to the tip portion 6b. The ceiling side support member 70 is filled with a sound absorbing material 38 such as glass wool.

  The wall-side support member 76 is a channel-shaped conductive member that opens to the indoor side as shown in FIG. 6, and has a groove bottom plate portion 72 attached to the wall surface by a fixture 66, and the side plate portion 74 outer surface And the folded-back plate portion 6a of the electromagnetic shielding plate 6 described above are freely inserted into the groove 18 on the side end surface of the panel material 2A through a conductive gasket 36. Other configurations are the same as those of the ceiling side auxiliary portion 70.

  The joint between the adjacent panel members 2A and 2A is shielded against electromagnetic waves by first and second engaging strips 20 and 30 having a bowl-shaped cross section as shown in FIG. These two engagement strips are obtained by extending the electromagnetic shielding plates 6 on both sides of the panel material outwardly in the left-right direction, and forming the extension plate portions in a cross-sectional shape, and the first engagement strips. The plate 20 refracts the distal end portion 22 outward in the thickness direction of the panel material, and the second engagement band plate 30 refracts the distal end portion 32 inward in the thickness direction of the panel material. The inner surface portions of both end portions of the second engagement band plates 20 and 30 are formed so as to be elastically press-contactable via a gasket 36 formed of a conductive elastic material, and each panel is connected via the gasket. The electromagnetic shielding surface portions on the front side or the back side of the material 2A are in electrical contact over the entire length of the seam. This gasket is preferably installed in contact with the front end of each band plate so as to prevent the generation of noise from the front end portions 32, 22 of the respective engagement band plates 20, 30. The gasket 22 may be omitted and the tip portions 22 and 32 may be in direct contact with each other. For example, as shown in FIG. 1, the gasket 36 may be attached in advance to the middle surface portion of the tip of either the first or second engagement band plate 20, 30. Further, the fitting groove 28 for insertion of the outer folding end portion 22 of the first engagement band plate 20 is formed between the end member 12 of each panel member 2A and the inner folding tip portion 32 of the second engagement band plate 30. Is forming. Furthermore, a space surrounded by the first and second engagement strips 20 and 30 and the end member facing end surfaces of both panel members 2A and 2A may be filled with a sound absorbing material 38 such as glass wool. In addition, it is desirable that the front side engagement band plates 20 and 30 and the back side engagement band plates 20 and 30 should not be in electrical contact with each other. Use as material.

  At the joint portion of the illustrated panel members 2A and 2A, the first engagement band plate 20 protrudes from the front electromagnetic shielding surface portion of one member, and the second engagement band plate 30 protrudes from the back electromagnetic shielding surface thereof. The second engagement band plate 30 protrudes from the front electromagnetic shielding surface portion of the other member and the first engagement band plate 20 protrudes from the back electromagnetic shielding surface portion of the other member. Is easy to remove. On the other hand, as shown in FIG. 8 as a modified example, a pair of first engagement band plates 20 and 20 are respectively provided from both electromagnetic shielding plates of one panel material, and a pair of second engagement band plates are provided from both electromagnetic shielding plates of the other panel material. 30 and 30 may be extended. Further, the first engagement band plate 20 is depressed from the base half portion 20a of the front half portion 20b with the outer folding front end portion 22 inwardly in the panel material thickness direction through a step portion 24 projecting inwardly. By doing so, a concave groove 26 that is long in the seam direction at the outer opening is formed between the stepped portion 24 and the outer folding front end portion 22. In order to press-contact the tip ends of the first and second engagement strips 20 and 30, an elastic joint material 40 formed of rubber or the like is fitted into the concave groove 26, and the joint material and the outer folding member are folded. What is necessary is just to press-fit the inner folding front-end | tip part 32 of the said 2nd engagement strip 30 between the inner side surface parts of a front-end | tip part. At this time, the outer surfaces of the base half portions 20a of the first and second engagement band plates 20 and 30 may be formed so as to be substantially flush with each other. For this purpose, as shown in FIG. The length obtained by subtracting the width d of the overlapping portion of the two end portions from the sum of the outward projecting width b and the inward projecting width c of the inner folding tip portion 32 also matches the step a of the step portion 24. It is good to provide.

  The joint portion between the lower end portion of the panel member 2A and the upper end portion of the edge member 2B is shielded by the first and second engaging strip plates 20 and 30 having a vertical cross-sectional shape as shown in FIG. ing.

  On the lower end portion side of the panel material 2A, the electromagnetic shielding plates 6 adhered to both the front and back surfaces of the sound insulating plate 8 are folded back from the lower end surfaces of the respective sound insulating plates 8 to the inner lower end portion of the sound insulating plate, and the folded plate portions. The first engagement strips 20 having the distal end portion 22 bent outwardly from the first projection band plate 20 are respectively projected. In addition, a hook-shaped fixing plate material 42 is attached between the folded plate portions, and a pressing rod 46 is provided through the bottom wall 44 of the fixing plate material, and a hole edge of the through hole and the pressing rod 46 are provided. The pressing bar 46 is formed so as to be able to advance and retract in the vertical direction by engraving screws for adjusting the panel material height on the outer surface. An elastic slider 48 is attached to the tip of the pressing rod 46, and the elastic slider is inserted into a runner 62 having a concave cross section. In order to prevent the generation of noise from the tip portion 6b of the electromagnetic shielding plate folded plate portion 6a, the fixed plate material 42, the pressing rod 46, and the elastic slider 48 are electrically conductive, and noise current is generated by the folded plate portion. It is desirable to make it flow from the front end portion 6b of 6a to the floor side via the fixed plate material 42 and the pressing rod 46. In this case, the front and back electromagnetic shielding plates 6 are in electrical contact with each other on the lower end side of the partition panel, but compared to the contact between the electromagnetic shielding plates at the joint portion between the panel materials, The impact is small. A sound absorbing material 38 is provided between the lower surface of the bottom wall 44 of the fixed plate member 42 and the upper surface of the elastic slider 48. A finishing baseboard 50 is suspended from the outer edge of the lower surface of the electromagnetic shielding plate.

  Further, on the upper end portion side of the edge member 2B, a second engagement band plate 30 having a tip portion bent inward from the front and back side plate portions 68, 68 of the runner 62 protrudes upward. The front end portion of the engagement band plate is elastically pressed to the front end portion 22 of the first engagement band plate 20 via the gasket 36.

  The first and second engagement band plates 20 and 30 between the lower end portion of the panel material 2A and the upper end portion of the edge member 2B are slid in the joint direction in order to facilitate the sliding of the panel member 2A with respect to the runner 62. It is desirable to provide movability. In a preferred illustrated example, the tip end portions 22 and 32 of the first and second engagement band plates 20 and 30 are provided so as to be gently curved so that the gasket 36 is wound around. Since the engagement strips are almost point-contacted, as shown in FIG. 2, the engagement strips 20 and 30 can be slid with less frictional resistance than the structure in which both engagement strips 20 and 30 are in surface contact. . However, as described later, a shield structure using a joint material may be used for the edge member 2B. Further, when the panel material 2A is pulled up from the state shown in FIG. 4, the first and second engagement band plates 20 and 30 are elastically deformed outward and the engagement is released. In addition, when the panel material 2A is lowered from the pulled-up state, the engagement band plate is deformed again to the outer side so that the front ends of both band plates are engaged. In addition, contrary to the illustrated example, the second engagement band plate 30 may be suspended from the panel material 2A side, and the first engagement band plate 20 may be erected from the runner 62 side.

  In the above configuration, when one panel member 2A is moved from the state of FIG. 1 to the other panel member 2A along the runner 62 of the edge member 2B as shown by the arrow, the first engagement band of each member is obtained. Since the snapping sensation is generated by forcibly getting over the leading end portion 22 of the second engagement band plate 30 of the other member on the leading end portion 22 of the plate 20, the engagement band plates are not locked to each other. There is no misunderstanding that it is locked. From this state, the elastic joint material 40 is fitted into the groove 26 described above, and the shield operation of the joint portion of the electromagnetic shield partition is completed. At this time, for example, when an external force is applied in a direction to bring the panel members 2A closer due to vibration such as earthquake motion, the external force is opposed to the external force by the elastic force of the joint material 40, and when an external force is applied in a direction to separate each member 2A, Since the distal end portions 22 and 32 of both the engagement band plates 20 and 30 are excessively pressed, there is no gap between the distal end portions.

  Next, FIG. 9 is a modified example of the configuration of the joint portion between the panel members 2A, and projecting portions 52, 52 project alternately from the half portions of the side end surfaces 12a, 12a of the end members 12, 12 of each panel member. By doing so, the space between the both end members is reduced, and the amount of the sound absorbing material 38 filled in the space is reduced, thereby facilitating the joining operation of the seam.

  FIG. 10 shows a modified example of the configuration of the joint portion between the panel member 2A and the edge member 2B. The first engagement band plate 20 with the concave groove 26 similar to FIG. 2 and the second engagement band The front and back surfaces of the joint portion are shielded with the plate 30. In the illustrated example, a first engagement band plate 20 that refracts the front end portion 22 outward and a second engagement that refracts the front end portion 32 inward from the lower end surfaces of the folded-back plate portions 6a of the electromagnetic shielding plates 6 on both sides. The band plate 30 is suspended, and the second and first engagement band plates 30 and 20 are erected from the front and back side plates 68 and 68 of the runner 62, respectively. An elastic joint material 40 is sandwiched in the groove 26, and a gasket 36 is sandwiched between the end portions 22 and 32 of the respective engagement strips. Further, the lower end surface of the core member 10 is closed by a hook-shaped fixing plate member 42, omitting the lower closing plate 16 shown in FIG. 4, and the fixing plate member is the lower surface of the sound insulating plate 8 of the panel material 2A. The lower half protrudes downward. The base end portions of the first and second engaging plate portions 20 and 30 hanging from the folded plate portion 6a side of the first electromagnetic shielding plate 6 are bent plate portions 82 folded inwardly. The front end portion (lower end portion) 52a and the front end portion 6b of the folded plate portion 6a of the electromagnetic shielding plate are in contact with the side plate portion of the fixed plate member 42.

  FIG. 11 shows an example in which a floor-side support member 78 that does not have a hook-shaped engagement band plate is provided in place of the edge member of FIG. The same components as those in FIG. 10 are denoted by the same reference numerals and description thereof is omitted. In the present embodiment, a conductive base board 50 is suspended from the folded back plate portion 6a of the electromagnetic shielding plate 6, and the lower end of the base board and an L-shaped leaf spring 56 projecting from the inner surface side of the base board are provided. The side plate portion 68 of the conductive runner 62 having a concave cross section is slidably held between the front end portion of the folded plate portion 6a and noise current flows to the floor side through the baseboard 50 and the runner 62. It is provided to flow. The base end side of the baseboard 50 is a bent plate portion folded back inward, and the distal end portion 52a of the bent plate portion is brought into contact with the side plate portion of the fixed plate member, and the bent plate portion and the fixed plate material 42 The baseboard 50 is fixed to the panel member 2A side by engaging a clip 54 projecting inwardly from the upper part of the baseboard 50 in an engaging hole 58 penetrating the side plate portion.

  FIG. 12 shows a modification of the ceiling side support member 70 shown in FIG. 5, from the upper surface of the upper blocking plate 14 to the upper inner surface portion of the sound insulating plate 8 from the upper end portion of the conductive plate 58 to the lower inner side. The leaf spring 56 protrudes at an acute angle, is folded back from the upper end side of the electromagnetic shielding plate 6 to the inside of the leaf spring 56, and the conductive ceiling having an inverted concave cross section fixed to the ceiling inside the folded plate portion 6a. A side support member 70 is fitted, and a noise current is allowed to flow from the front end portion of the folded plate portion 6a to the ceiling side via the ceiling side support member 70. Note that a space between the conductive plate 60 and the ceiling side support member 70 may be filled with a shield filler 80 such as metal cilia.
