Description

  The present invention relates to a partition frame structure, and more particularly to a partition frame structure that electromagnetically shields a space in a building at low cost.

  In the advanced information era, buildings that include offices (hereinafter simply referred to as buildings) are constructed so as to be compatible with advanced information. For example, in addition to general environmental management and building management functions, information communication facilities such as office automation, data processing, and telecommunication are provided.

  Data transmission / reception between buildings corresponding to advanced informationization is performed by high-speed and large-capacity communication using optical fibers, gigabit or terabit transmission using communication cables, and the like. Inside the building, a plurality of personal computers are connected to each other to send and receive the Internet and e-mail. In addition, various other electronic devices are arranged inside the building corresponding to advanced informationization, and control signals for controlling them are transmitted and received by the arranged communication cables and the like. It is configured.

  Further, for example, offices, conference rooms, laboratories, factories, etc. are provided inside the building. For example, in the laboratory, a large number of electronic devices such as personal computers, printers, scanners, servers, etc. are installed. Are connected to each other by a dedicated cable or the like so as to be controllable.

  Connection of various electronic devices using dedicated cables, etc. is complicated due to an increase in the number of electronic devices to be connected and higher performance of the devices, and problems such as cable miswiring and disconnection occur, and maintenance of various electronic devices is further managed. It's getting harder. Therefore, in recent years, so-called wireless LANs and wireless networks, etc., in which wired cables are abolished and wireless connection is made active.

  When a wireless network is constructed, data can be transmitted / received to / from each electronic device by simply connecting a simple transceiver to each electronic device, and a wired cable or the like is unnecessary, which is useful. For example, in order to connect a plurality of personal computers to each other, a wireless router or the like may be used, and the Internet or electronic mail can be exchanged using this wireless router.

  However, in order to construct a wireless network in one space in a building, it is necessary to appropriately select a radio frequency band to be used. In other words, since radio waves leak from one space in the building, radio waves to be used must be those managed by the Radio Law. If the frequency band is arbitrarily selected and used, for example, a medical device installed in a nearby building may be adversely affected, such as malfunction, operation stop, or burning. Medical device malfunctions affect human life and must be prevented. In addition, various electronic devices may malfunction due to leaked radio waves. Accordingly, the frequency band that can be used is limited and cannot be freely selected.

  Also, depending on the structure of the building, radio waves may leak into the space (room) that is partitioned next to each other. Therefore, even if the radio waves are managed by the Radio Law and the frequency and intensity are predetermined. In some cases, the same frequency band cannot be used in adjacent rooms. Furthermore, since radio waves leak, there is a problem that data, conversations, etc. are wiretapped.

  In addition, a radio network and a radio communication network in one space in the building may be disturbed by radio waves entering from outside the building. If this type of jamming signal enters when data is being sent / received, the data currently being sent / received must be discarded, and if there is a high cost for sending / receiving data, When urgency is being questioned, the suspension of data transmission / reception due to this jamming radio wave becomes a problem.

  Therefore, a space in the building is covered with an electromagnetic shielding material to form a so-called anechoic chamber or electromagnetic shielding space, and a device has been devised so that the used radio waves do not leak and that interference radio waves do not enter from outside. ing.

  The electromagnetic shield / intelligent building disclosed in Patent Document 1 discloses a technology in which a building frame is formed of concrete containing an electromagnetic shielding member, and communication is performed using radio waves between communication devices in the building.

  The concrete with the electromagnetic shielding member is ferrite-containing concrete or mesh-containing concrete. If a building frame is constructed with such concrete, each room separated by the concrete becomes an electromagnetic shielding space or an anechoic chamber, and wireless Communication between electronic devices is possible. Furthermore, it is a configuration that can prevent the intrusion of jamming waves from the outside. In such an electromagnetic shielding space, radio waves to be used do not leak outside the building, so that it is possible to arbitrarily select a frequency band.

  However, using concrete with an electromagnetic shielding member to make the entire building an electromagnetic shielding space is large and costly. However, even a space that does not need to be electromagnetically shielded is electromagnetically shielded, which causes a problem that a mobile phone inside the mobile phone cannot be connected to a mobile phone outside the building or a repeater.

  In the intelligent building of Patent Document 2, the floor structure is doubled and the inside of the underfloor space is covered with an electromagnetic shielding material to form an electromagnetic shielding space, and this underfloor space is connected to a repeater and a terminal connected to a communication line. A technique for installing a transmitter is disclosed. He argues that this method will build an intelligent building that can reduce costs and can be easily handled in terms of reliability through simple construction. According to this disclosed method, since the underfloor space is an electromagnetic shielding space, wireless communication between electronic devices is possible. Furthermore, it is a configuration that can prevent the intrusion of jamming waves from the outside. Therefore, in the electromagnetic shielding space, the radio wave to be used does not leak outside the building, so that the frequency band can be arbitrarily selected. In addition, radio waves in the same frequency band can be used in adjacent rooms, which can be said to be very useful.

  However, it cannot be denied that it is expensive to make the floor structure double and to cover the inside of the underfloor space with an electromagnetic shielding material. However, since repeaters and transmitters (transmitters / receivers) are installed in the underfloor space, it is not easy to connect these repeaters and transmitters to electronic devices outside the shielded space, and maintenance management is troublesome. is there.

  Furthermore, according to the radio wave absorber of Patent Document 3, for example, a light and radio wave shield configured to shield radio waves using a liquid crystal plate that can transmit or block light by electric field control, It is described that it is extremely effective if it is used as a partitioning material or the like in a building or the like that has indoor radio equipment. Certainly, if the space is covered with such an electromagnetic shield, an anechoic chamber is formed.

  However, even if such an electromagnetic shield is extremely effective, covering the entire space to be shielded by the electromagnetic shield is expensive and the work is not easy. Therefore, it is difficult to construct an electromagnetic shielding space easily at low cost.

  Any of the above-described conventional techniques has involved considerable difficulty in constructing the electromagnetic shielding space easily at a low cost.

  Accordingly, the present invention has been made in view of the above-described problems in the prior art, and an object thereof is to provide a partition frame structure capable of constructing a space for electromagnetic shielding easily at low cost.

  The frame structure of the partition of the present invention includes a metal upper runner fixed to the ceiling surface, a metal lower runner fixed to the floor surface, and the upper runner and the lower runner extending vertically. A frame structure of a partition composed of a plurality of metal studs disposed between and a plurality of metal connection plates electrically connected to the studs and disposed in a direction perpendicular to the studs. The upper runner, the lower runner, the stud, and the connection plate are disposed on four surfaces excluding the ceiling surface and the floor surface of the electromagnetic shielding space, and the upper runner and the lower runner are belt-shaped. And a plurality of metal protrusions protruding from the base at intervals in the extending direction of the base, and the stud is the protrusion. Configured to be matable with the previous The upper runners and the lower runners are electrically connected to each other, and the diagonal length of the rectangular region partitioned by the upper runner, the stud, and the connection plate, and the lower runner, the stud, and the connection. The length of the diagonal line of the rectangular area partitioned by the plate and the length of the diagonal line of the rectangular area partitioned by the stud and the connection plate are set to be equal to or less than the wavelength of the radio wave to be shielded, The lower runner is electrically connected to the steel frame inside the building.

  A frame structure composed of the upper runner, the lower runner, the stud, and the connection plate is disposed on four sides except for the ceiling surface and the floor surface of the space to be shielded. Here, it is assumed that the ceiling surface and the floor surface are made of concrete containing an electromagnetic shielding material, for example.

  The upper runner and the lower runner include a base portion and a convex portion. The base portion is made of a metal flat plate, and the thickness and width thereof can be appropriately determined in consideration of the size of the space to be shielded, the material of the base material and wall material used, the weight, and the like. The material of the base can be appropriately selected from iron, copper, aluminum and the like. In view of cost, iron is the most desirable.

  The convex portion is provided at a predetermined interval on the base portion, and the convex portion is made of metal, and a stud described later is fitted into the convex portion to position the stud. is there. The dimensions, material, surface roughness, and the like of this convex portion can be determined as appropriate in relation to the stud and the base portion of the upper and lower runners. For example, the convex portion can be formed in a box shape or a gate shape with a metal plate made of the same material as the base portion, and both ends thereof can be attached to the base portion by bolting, spot welding, riveting, nails or the like. Moreover, although a convex part may be a solid body of metal, a hollow body is desirable in consideration of the weight of the upper and lower runners.

The stud is formed to extend linearly from a metal member, and both ends of the stud are configured to be fitted to the metal protrusion.
The connection plate is a metal flat plate that electrically connects the stud and is disposed in a direction perpendicular to the stud. The material, width, etc. can be determined as appropriate. As will be described later, the connection plate has a rectangular length partitioned by the upper runner, the stud, and the connection plate, and a rectangular region partitioned by the lower runner, the stud, and the connection plate. The diagonal length of the region and the diagonal length of the rectangular region partitioned by the stud and the connection plate are one or more in a direction perpendicular to the stud and plural so that the wavelength is equal to or less than the wavelength of the shielding radio wave. It is arranged along the stud and connected. The electrical connection between the connection plate and the stud can be appropriately selected from methods such as spot welding, bolting, and riveting.

  The outer periphery of the ceiling surface and the floor lower surface is surrounded by an upper runner and a lower runner, respectively. At this time, when the upper runners and the lower runners are connected and arranged, the end portions overlap so that the upper runners and the lower runners are always electrically connected at the connection portion. It is important to do so.

  The diagonal length of the rectangular area partitioned by the upper runner, the stud and the connecting plate, the diagonal length of the rectangular area partitioned by the lower runner, the stud and the connecting plate, and the stud The length of the diagonal line of the rectangular region partitioned by the connection plate is set to be equal to or less than the wavelength of the electromagnetic wave to be shielded. If the frequency band of the electromagnetic wave to be shielded is determined in advance, it is necessary to determine the interval between the convex portions and the interval at which the connection plate is disposed so as to satisfy the above relationship. For example, when shielding the radio wave of 300 Mhz, if the upper runner, the lower runner, the stud, and the connecting plate are arranged so that the rectangular region is a square, the spacing between the convex portions The distance between the connection plates is approximately 0.71 m. This can be determined from the relationship c = f · λ, where λ is the wavelength, f is the frequency, and c is the speed of light.

  The upper runner and / or the lower runner are electrically connected to a steel frame inside the building. The connection location may be any location of the upper runner or the lower runner. Both the upper runner and the lower runner may be connected to a steel frame. A cable, a wire, etc. can be used for the connection with a steel frame. The base of the upper and lower runners may be extended and connected to the steel frame.

  Therefore, according to the partition frame structure of the present invention, the frame structure of the electromagnetic shielding space can be formed easily and at low cost with work efficiency by the upper and lower runners, the studs, and the connection plate.

  The frame structure of the partition of the present invention includes a metal upper runner fixed to the ceiling surface, a metal lower runner fixed to the floor surface, and the upper runner and the lower runner extending vertically. A frame structure of a partition composed of a plurality of metal studs disposed between and a wire mesh that is electrically connected to the plurality of studs and disposed along the studs. The upper runner, the lower runner, the stud, and the wire mesh are disposed on four surfaces excluding the ceiling surface and the floor surface, and the upper runner and the lower runner are strip-like metal that extends linearly. It is composed of a base portion made of a flat plate and a plurality of metal convex portions protruding from the base portion with an interval in the extending direction of the base portion, and the stud is configured to be fitted with the convex portion, The upper runners and front The lower runners are electrically connected to each other, the wire mesh is attached to the four sides, and the length of the diagonal line of one mesh of the wire mesh is set to be equal to or less than the wavelength of the shielding radio wave, And / or the said lower runner is electrically connected with the steel frame inside a building, It is characterized by the above-mentioned.

  A frame structure composed of the upper runner, the lower runner, the stud, and the wire mesh is disposed on four surfaces except for the ceiling surface and the floor surface of the space to be shielded. Here, it is assumed that the ceiling surface and the floor surface are made of concrete containing an electromagnetic shielding material, for example.

  The upper runner, the lower runner, and the stud are as described above. If the wire mesh is conductive, the thickness of the wire constituting the wire mesh, the mesh pattern, the shape of the mesh, the welding method of the portion where the wire and the wire intersect when forming the mesh, etc. Absent. Therefore, a fence net, a wire mesh, a bar mesh, or a punching metal may be used. Here, the surface of the wire mesh may be painted or the like, but it is necessary to remove the coating of the portion that makes electrical connection between the upper and lower runners and the stud. In addition, when adding a short wire mesh, it is necessary to be careful not to create a gap at the connecting portion. Connection of wire meshes at the connecting portion can be appropriately performed using an auxiliary jig or the like.

  However, as the size of the mesh, the longest length of straight lines connecting the corners is equal to the wavelength of the electromagnetic wave to be shielded. That is, if the mesh is square, the diagonal line is equal, if the mesh is rectangular, the longer diagonal line, if the mesh is circular, the diameter is equal, and if the mesh is elliptical, the major axis diameter is equal to the wavelength of the electromagnetic wave to be shielded. In the case of a triangle, the length of each side or the height of each side can be defined as three bases, but the highest of these heights is made equal to the wavelength of the electromagnetic wave to be electromagnetically shielded. . If punched metal is used, similarly, if the hole shape to be punched is rectangular, the length of the diagonal line is rounded. Equal to the wavelength.

  Therefore, according to the partition frame structure of the present invention, the frame structure of the electromagnetic shielding space can be formed easily and at low cost with work efficiency using the upper and lower runners, the studs, and the wire mesh.

  The frame structure of the partition of the present invention includes a metal upper runner fixed to the ceiling surface, a metal lower runner fixed to the floor surface, and the upper runner and the lower runner extending vertically. A partition frame structure comprising a plurality of metal studs disposed between and a metal stay electrically connected to the plurality of studs and disposed along the studs, wherein the space is electromagnetically shielded. The upper runner, the lower runner, the stud, and the metal stay are disposed on four surfaces except the ceiling surface and the floor surface of the upper runner, and the upper runner and the lower runner extend in a straight line in a strip shape. And a plurality of metal convex portions protruding from the base portion at intervals in the extending direction of the base portion, and the stud is configured to be fitted with the convex portion. And the above runners The lower runners are electrically connected to each other, the metal stays are attached to the four sides, and the upper runner and / or the lower runner are electrically connected to a steel frame inside the building. It is characterized by.

  A frame structure composed of the upper runner, the lower runner, the stud, and the metal foil is disposed on four sides except for the ceiling surface and the floor surface of the space to be shielded. Here, it is assumed that the ceiling surface and the floor surface are made of concrete containing an electromagnetic shielding material, for example.

  The upper runner, the lower runner, and the stud are as described above. As long as the metal foil has electrical conductivity, its thickness and material are not limited. Accordingly, aluminum foil, stainless steel foil, or the like can be used as appropriate. Here, the metal foil is affixed to another support, and the support may be installed between the studs. In this case, however, the metal foil, the upper and lower runners, and the stud are reliable. Make sure that the electrical connection is made. When adding a short metal foil, care must be taken not to create a gap at the joint. Moreover, although the process of coating etc. may be given to the surface of metal foil, the said metal foil needs to be electrically connected with the said up-and-down runner and the said stud also in this case.

  Therefore, according to the partition frame structure of the present invention, the frame structure of the space to be electromagnetically shielded can be easily and inexpensively formed by the upper and lower runners, the studs and the metal foil with high work efficiency.

  In the frame structure of the partition of the present application, the stud is formed by extending a straight line with a hollow metal member, and both ends of the stud can be fitted to the metal projections, It is positioned on the surface orthogonal to the direction in which the stud extends by being fitted to the convex part, and the convex part of the lower runner and the lower end of the stud are held in the fitted state when they are fitted. The upper runner convex portion and the stud upper end are formed to be slidable in the direction in which the convex portion is fitted.

  Accordingly, the stud is positioned on a surface orthogonal to the direction in which the stud extends, and the convex portion of the upper runner and the upper end of the stud are formed to be slidable in the direction in which the convex portion is fitted. Therefore, the distance between the upper end of the stud and the base of the upper runner can be adjusted.

  The frame structure of the partition of the present application includes the upper runner and the lower runner in the state in which the convex portions of the upper runner and the lower runner are fitted until their base portions are in contact with both ends of the stud. The distance between the lower surface of the lower runner is shorter than the distance between the ceiling surface and the floor surface, and the lower surface of the lower runner is placed on the floor surface from the state where the lower runner is tilted on the floor surface. In a state where the upper runner is pulled out while maintaining the fitting state with the stud, the upper runner is formed with dimensions that can stand up so as to be positioned on the side, and between the upper surface of the upper runner and the lower surface of the lower runner. The distance is formed with a dimension equal to the distance between the ceiling surface and the floor surface.

  Accordingly, it is possible to efficiently form the partition frame structure of the space to be electromagnetically shielded in a short time.

  The partition frame structure of the present application is characterized in that the convex portion is configured such that a metal flat plate is bent in a gate shape and both ends of the flat plate are joined to the base portion. The connection between both ends and the base can be attached by bolting, spot welding, riveting, nails or the like as described above. In this way, it is possible to easily form the convex portion at the base of the upper and lower runners at a low cost.

  The partition frame structure of the present application is characterized in that the stud is a square metal hollow pipe. Since it is a square hollow pipe, it can be easily fitted with the convex portion, and the connection plate can be easily arranged. Furthermore, it becomes easy to attach a base material or a wall material to the stud.

  The frame structure of the partition of the present application has a rectangular window penetratingly formed at a plurality of positions spaced in the extending direction of the base, and one set of corners of the two opposing corners of the window In addition, a center line extending in the extending direction of the base portion through the center in the width direction of the base portion is located.

  When forming the frame structure of the shielding space, the ink marking line is attached by marking the area where the frame structure is formed in advance. The size of the window can be arbitrarily determined as long as the marking line can be seen. However, if the window is formed larger, the strength of the base portion of the upper and lower runners is lowered. The upper and lower runners can be efficiently arranged at regular positions by aligning the inking line with one set of corners of the two opposing corners of the window. In this way, it is possible to install the upper and lower runners at a predetermined position with high accuracy.

  In the frame structure of the partition of the present invention, the ceiling surface of the electromagnetic shielding space is configured by connecting the connection plate vertically and horizontally to the upper runner surrounding the outer periphery of the ceiling surface, and is a rectangular shape partitioned by the connection plate. The length of the diagonal line of the region is equal to or less than the wavelength of the electromagnetic wave to be shielded, or the wire mesh is arranged on the upper runner surrounding the outer periphery of the ceiling surface, and the length of the diagonal line of one mesh of the wire mesh Is not more than the wavelength of the electromagnetic wave to be shielded, or is configured by arranging the metal stay on the upper runner surrounding the outer periphery of the ceiling surface.

  The connection plate and the wire mesh may be directly attached to the ceiling surface, and the metal foil may be directly attached to the ceiling surface. However, the connection plate, the wire mesh, and the metal foil are configured to be electrically connected to the upper and lower runners. By arranging a connection plate, a wire mesh, or a metal foil on the ceiling surface, it is possible to prevent electromagnetic waves from entering and leaking from the ceiling surface. In this way, a more complete shielding space can be formed.

  In the frame structure of the partition of the present invention, the floor surface of the electromagnetic shielding space is configured by connecting the connection plate vertically and horizontally to the lower runner surrounding the outer periphery of the floor surface, and is a rectangular shape partitioned by the connection plate. The diagonal length of the region is equal to or less than the wavelength of the electromagnetic wave to be shielded, or the wire mesh is arranged on the lower runner surrounding the outer periphery of the floor surface, and the diagonal length of one mesh of the wire mesh Is less than the wavelength of the electromagnetic wave to be shielded, or the metal stay is arranged on the lower runner surrounding the outer periphery of the floor surface.

  The connection plate and the wire mesh may be directly attached to the floor surface, or the metal foil may be directly attached to the floor surface. However, the connection plate, the wire mesh, and the metal foil are configured to be electrically connected to the upper and lower runners. By arranging a connection plate, a metal mesh, or a metal foil on the floor surface, it is possible to prevent electromagnetic waves from entering and leaking from the floor surface. In this way, a more complete shielding space can be formed.

  The frame structure of the partition of the present invention is characterized in that a repeater for a mobile phone is arranged in an electromagnetic shielding space, and that the mobile phone can talk between the inside and the outside of the electromagnetic shielding space. And

  The repeater includes a transmitter and a receiver, receives radio waves from outside the shielded space, transmits the received radio waves to the mobile phone inside the shielded space, and carries the mobile phone inside the shielded space. It has a function of receiving radio waves from a telephone and transmitting radio waves outside the shielded space. The configuration is not particularly limited as long as this function can be realized. Therefore, even if a mobile phone is brought into the shielding space, the mobile phone can be used without any problem.

  The wire mesh may be replaced by punching metal as described above.In that case, when the hole shape of the punching metal is rectangular, the length of the diagonal line is less than or equal to the wavelength of the electromagnetic wave to be shielded, or If the hole shape of the punching metal is circular, the diameter must be less than or equal to the wavelength of the electromagnetic wave to be shielded, or if the hole shape of the punching metal is elliptical, the major axis diameter must be less than or equal to the wavelength of the electromagnetic wave to be shielded. There is. Further, a fence net may be used. In that case, the length of the diagonal line of the rhombus mesh shape of the fence net is set to be equal to or less than the wavelength of the electromagnetic wave to be shielded.

  Moreover, you may use what was comprised by apply | coating a conductive paint instead of the said metal stay. For example, a conductive paint is applied to one side of a thin resin plate, and a resin plate coated with the conductive paint is placed between the studs. In this case, the conductive paint is configured to be electrically connected to the stud and the upper and lower runners.

The frame structure of the electromagnetic shielding space is formed by the following procedure.
1. Ink out the space that is electromagnetically shielded. Perform on both floor and ceiling. Inking is performed, and the place where the upper and lower runners are installed is marked with an inking line.

2. An upper runner, a lower runner, studs, and the like whose convex portions are attached at predetermined intervals in advance at the factory are carried near the inking line and temporarily arranged there.

3. On the floor, insert studs into the convex parts of the upper and lower runners. The stud is fitted to the convex portions of the upper runner and the lower runner until the end of the stud comes into contact with the base. The number of studs to be fitted is about several. A frame made up of the upper runner, the lower runner, and a plurality of studs thus completed is referred to as a partial frame. This partial frame is large enough to be carried by hand. Note that a partial frame may be manufactured in advance at the factory, and the partial frame may be carried to the site. In addition, if the connection plate is attached to the stud of the partial frame as necessary, the work efficiency at the site is further improved.

4). Stand the partial frame and fix the lower runner's lower surface correctly on the ink marking line on the floor, and the upper runner pull out the convex part from the end of the stud and place it correctly on the ink marking line on the ceiling. To do. The upper runner can be fixed to the ceiling, and the lower runner can be fixed to the floor using stoppers, nails or the like.

5. The above four operations are performed along the four sides of the space except the ceiling and floor. At this time, at the portion where the upper runner and the lower runner are joined, the respective end portions are overlapped and fixed with a stopper, a nail or the like so as not to cause an electrical connection failure. Or you may joint by the nail | claw and hole which were formed in the edge part of an up-and-down runner.

6). The partial frames are sequentially attached as described above, and the upper and lower runners and studs are formed on the four surfaces except the ceiling surface and floor surface of the space to be shielded. Thereafter, the connection plate is attached. The connection plate has a diagonal length of a rectangular region partitioned by the upper runner, the stud, and the connection plate, and a diagonal length of a rectangular region partitioned by the lower runner, the stud, and the connection plate. In addition, a plurality of pieces are attached so that the diagonal length of the rectangular region partitioned by the stud and the connecting plate is equal to or less than the wavelength of the radio wave to be shielded. The joining of the stud and the connection plate can be appropriately adopted from methods such as spot welding, bolting, and riveting.

7). After forming the frame structure of the space to be electromagnetically shielded, one of the upper runner and the lower runner is electrically connected to the internal steel frame constituting the building.

  In addition, although the above demonstrated the procedure in the case of constructing shielding space using a connection board, when using a metal mesh or metal foil without using a connection board, the above-mentioned 6. It is almost the same until. Thereafter, a wire mesh or a metal foil is disposed along the stud. And any part of the said upper runner and the said lower runner is electrically connected with the internal steel frame which comprises a building.

With the above configuration, the following effects can be expected.
Each part (upper and lower runners, studs, connecting plates, wire mesh, metal foil, etc.) constituting the frame structure of the partition is formed with high accuracy in the factory beforehand, and these are carried to the site, and the partial frame is installed on the site. By assembling and sequentially connecting the assembled partial frames, the frame structure of the partition for electromagnetic shielding can be easily realized at low cost.

  In this electromagnetic shielding space, the diagonal length of the rectangular area partitioned by the upper runner, the stud and the connection plate and the diagonal line of the rectangular area partitioned by the lower runner, the stud and the connection plate Electromagnetic waves having the wavelength of the length of the diagonal line of the rectangular region partitioned by the stud and the connection plate cannot enter the shielded space. Longer-wavelength radio waves cannot penetrate as well.

  When a wire mesh is used instead of the connection plate, the same effect as described above can be expected when the length of the diagonal line of one mesh of the wire mesh is made equal to or less than the wavelength of the radio wave to be shielded. Moreover, when comprised with metal foil, substantially all electromagnetic waves can be shielded.

  Therefore, when a wireless LAN or the like is constructed using the wavelength in the shielded space, the radio wave does not leak outside from the shielded space, and there is no fear of leakage of trade secrets. There is no risk of interference or interference even if the same radio waves are used in adjacent spaces.

  According to the partition frame structure of the present invention, the frame structure of the electromagnetic shielding space can be formed easily and at low cost with work efficiency by the upper and lower runners, the studs, the connection plate, the wire mesh, or the metal foil. Become. That is, an electromagnetic shielding space can be realized at an arbitrary location inside the building with high accuracy and at low cost.

  Hereinafter, embodiments of the partition frame structure of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a schematic perspective view of a frame structure constituting an electromagnetic shielding space according to the partition frame structure of the first embodiment of the present invention. Frame structures are arranged on four surfaces except the ceiling surface and floor surface of the space to be electromagnetically shielded, and the ceiling surface and floor surface are made of concrete including an electromagnetic shielding material. Therefore, there is no need to consider leakage or intrusion of radio waves from the ceiling surface and the floor surface.

  The frame structure constituting the electromagnetic shielding space is formed by the upper runner 1, the lower runner 2, the stud 3, and the connection plate 4. In the following description, for example, when described as the base portions 1a and 2a, it means that the base portion of the upper runner 1 is 1a and the base portion of the lower runner 2 is 2a. Similarly, in the case of the convex portions 1b and 2b, 1b means the convex portion of the upper runner 1, and 2b means the convex portion of the lower runner 2.

  The upper and lower runners 1 and 2 have substantially the same structure, and as shown in FIGS. 2A to 2C, a plurality of base portions 1a and 2a extending linearly and a plurality of base portions 1a and 2a protruding from the base portions 1a and 2a. Convex portions 1b and 2b are provided. The bases 1a and 2a are formed of a strip-shaped flat steel plate having a thickness of about 1 mm and a uniform width.

  In order to connect the upper runners 1 or the lower runners 2, although not shown, joint holes and claws are formed at the ends of the upper and lower runners 1 and 2. In other words, when connecting the runners, connect the joint claw provided at the other end upright by inserting the joint claw provided at the other end and then bending the joint claw. Is done.

  The convex portions 1b and 2b are formed in a gate shape using flat steel made of the same material as the upper and lower runners, and both end portions 1e and 2e are bent inward and fixed by spot welding 1d and 2d. The magnitude | size of the convex parts 1b and 2b is a magnitude | size which the stud 3 can just fit.

  The intervals between the protrusions 1b and 2b on the bases 1a and 2a are the length of the diagonal line of the rectangular region partitioned by the upper runner 1, the stud 3, and the connection plate 4, and the lower runner 2, the stud 3, and the connection plate 4. The length of the diagonal line of the rectangular area partitioned by and the length of the diagonal line of the rectangular area partitioned by the stud 3 and the connecting plate 4 was set to approximately 0.71 m. However, the rectangular area to be partitioned was a square. As a result, a shielded space can be configured for 300 Mhz radio waves.

  As shown in FIG. 2 (d), the windows 1c and 2c are formed in a rectangular shape so as to penetrate the bases 1a and 2a, and are appropriately disposed at a plurality of positions at intervals of the bases 1a and 2a. Is provided. By adjusting the positions of the upper and lower runners 1 and 2 such that the ink marking line 10 is positioned exactly at one of the two corners 1f and 2f of the two opposing corners of the windows 1c and 2c. The upper and lower runners 1 and 2 are arranged at regular positions. The windows 1c and 2c are formed with high accuracy by laser processing.

  As the stud 3, a square hollow metal pipe was used as shown in FIG. The lateral width 3a of the stud 3 and the widths of the upper and lower runners 1 and 2 are substantially the same. The thickness of the stud 3 was appropriately determined in consideration of the base material and wall material attached to the stud 3. The relationship between the cross-sectional dimension of the stud 3 and the protrusions 1b and 2b is as follows. The lower end of the stud 3 and the convex portion 2b of the lower runner 2 are formed so as to keep the state once fitted, and the upper end of the stud 3 and the convex portion 1b of the upper runner 1 can slide after being fitted once. It is formed as follows. That is, after the upper and lower runners 1 and 2 and the stud 3 are fitted, the distance between the upper surface of the upper runner 1 and the lower surface of the lower runner 2 can be adjusted.

  As shown in FIG. 4, the connecting plate 4 is made of the same flat steel as the flat steel forming the bases 1 a and 2 a of the upper and lower runners 1 and 2. The width 4a of the connecting plate is substantially the same as the width of the upper and lower runners 1 and 2. However, the widths 4a are not necessarily the same, and the width 4a can be arbitrarily determined as long as electrical conduction is ensured.

Next, the assembly procedure of the frame structure that forms the electromagnetic shielding space will be described.
First, the upper and lower runners 1 and 2, the stud 3 and the connection plate 4 are carried into the site. The ink is drawn out in the space where electromagnetic shielding is applied to the ceiling surface and the floor surface, and the ink drawing line 10 is attached. This inking line 10 is an important line for determining the position of the frame structure.

  Next, in the field, the lower end of the stud 3 and the convex part 2b of the lower runner 2 are fitted, and the upper end of the stud 3 and the convex part 1b of the upper runner 1 are fitted. Several studs 3 are fitted to each of the upper and lower runners 1 and 2. As a result, the lower end of the stud 3 and the convex portion 2b of the lower runner 2 are kept in a fitted state, and the upper end of the stud 3 and the convex portion 1b of the upper runner 1 are slidably fitted. A frame 8 is formed.

  FIG. 5 shows the partial frame 8 and is a plan view (a), a front view (b), and a side view (c). 5A to 5C, the convex portions 1 and 2b are indicated by solid lines in order to display their positions. If this partial frame 8 is assembled at a factory and then brought into the field, work efficiency is good. In some cases, it may be possible to attach the connection plate 4 to the stud 3. FIG. 5 (d) shows a state of fitting between the lower end of the stud 3 and the convex portion 2 b of the lower runner 2. The stud 3 is fitted until it contacts the base 2a of the lower runner 2. Thus, the stud 3 is positioned by fitting the stud 3 to the convex portion 2 b of the lower runner 2.

  As will be described later, the overall size of the partial frame 8 is such that the partial frame 8 is erected and the upper and lower runners 1 and 2 are fixed to the ceiling surface and the floor surface, respectively. The size is portable. If the size is too large, the weight increases, which is dangerous. If the size is too small, the work efficiency is deteriorated. Therefore, the size in which about four studs 3 are fitted to the upper and lower runners 1 and 2 is just right.

  Next, the partial frame 8 is erected so that the lower runner 2 is positioned on the floor surface and the upper runner 1 is positioned on the ceiling surface at the location where the partial frame 8 is marked. In this case, the convex portion 1b of the upper runner 1 is pushed into the upper end of the stud 3 so that the partial frame 8 rises smoothly, and the base 1a of the upper runner 1 is applied to the upper end of the stud 3, The height of the frame 8 is kept low. Next, the partial frame 8 is erected, and the lower runner 2 is positioned so that a set of corners 2f of the plurality of windows 2c of the lower runner 2 is positioned exactly on the ink line 10 attached to the floor surface. Then, the convex portion 1b of the upper runner 1 is pulled out from the stud 3 and applied to the ceiling surface, and a set of corner portions 1f of the plurality of windows 1c of the upper runner 1 is located just at the ink line 10 attached to the ceiling surface. The upper runner 1 is positioned so as to In the state where the upper runner 1 and the lower runner 2 are positioned as described above, the lower runner 2 and the upper runner 1 are fixed to the floor surface and the ceiling surface by the concrete nails, respectively.

  FIG. 6 is a schematic cross-sectional view showing a state in which the upper runner 1 and the lower runner 2 are fixed to the ceiling surface 6 and the floor surface 7 respectively as described above, and the upper runner 1 and the lower runner 2 are respectively It is fixed by a concrete nail 5. The convex portion 1 b of the upper runner 1 is slightly away from the stud 3 so that the distance between the upper surface of the upper runner 1 and the lower surface of the lower runner 2 is exactly equal to the distance between the ceiling surface 6 and the floor surface 7. It has come out.

  FIG. 7 is a plan view showing a state when three partial frames 8 are arranged side by side so as to be positioned on the same straight line when viewed in plan. In FIG. 7, a connection portion between the partial frame 8 and the partial frame 8 is indicated by a one-dot chain line. The connection between the upper runners 1 and the connection between the lower runners 2 are overlapped with each other using joint holes and claws (not shown) provided at the ends of the upper and lower runners 1 and 2. To ensure a secure electrical connection.

  Thereafter, the connection plate 4 is connected to the stud 3. A plurality of connection plates 4 are arranged between the ceiling surface 6 and the floor surface 7 as necessary. That is, the diagonal length of the rectangular region partitioned by the upper runner 1, the stud 3 and the connecting plate 4, the diagonal length of the rectangular region partitioned by the lower runner 2, the stud 3 and the connecting plate 4, and In order to make the length of the diagonal line of the rectangular region partitioned by the stud 3 and the connection plate 4 equal to or less than the wavelength of the radio wave to be shielded, a plurality of pieces are connected as necessary. The stud 3 and the connection plate 4 were connected by spot welding.

  As described above, the frame structure of the space for electromagnetic shielding is completed. Thereafter, the end of the lower runner 2 corresponding to one set of corners of the two opposite corners of the floor surface 7 of the shielded space is connected to the steel frame inside the building by a wire. The steel frame inside the building shall be grounded and grounded. Then, the base material and wall material are attached to the stud 3 on both sides of the frame structure, thereby completing the partition.

  According to the first embodiment of the present invention, since the upper and lower runners, studs, and connecting plates constituting the frame structure can be manufactured with high accuracy in the factory in advance, the upper and lower runners and studs are assembled at the site. Make a frame, or attach a connecting plate if necessary, make it at the factory, stand up this partial frame at the site and install the upper and lower runners in line with the ink line, so that it is in the correct position A frame structure that realizes an electromagnetic shielding space with high accuracy and low cost is formed.

  In this frame structure, that is, in the shielded space, the length defined above (the length of the diagonal line of the rectangular area divided by the upper runner, stud and connecting plate and the lower runner, stud and connecting plate) It is possible to freely use radio waves whose wavelength is the length of the diagonal line of the rectangular area to be partitioned and the length of the diagonal line of the rectangular area divided by the stud and the connecting plate. The radio waves never leak. Also, radio waves of that wavelength do not enter from the shielding space. Note that a radio wave having a higher frequency than a radio wave having a wavelength defined by the above-described interval has a shorter wavelength than the interval defined by the above-described radio frequency, and thus the shielding effect is small.

  Therefore, a wireless network is constructed using radio waves having the intervals defined above as wavelengths, and the frequency of the mobile phone used inside the shielded space is set to be higher than radio waves having the intervals defined above as wavelengths. If a high frequency is set, the mobile phone can be used in this shielded space without any trouble. In other words, even inside the shielded space, it is possible to talk with a mobile phone outside the shielded space.

  In addition, if a shielded space is formed in each adjacent space in a building, even if the same radio wave is used, it does not leak into the adjacent space, so that a wireless network or the like can be formed efficiently. Furthermore, since radio waves do not leak, problems such as conversational wiretapping do not occur.

(Second embodiment)
FIG. 8 is a schematic perspective view illustrating a second embodiment of the partition frame structure of the present invention. The difference from the first embodiment is that a connection plate is connected vertically and horizontally to the ceiling surface and the floor surface of the space to be shielded to shield radio waves entering from the ceiling surface and the floor surface. That is, in the first embodiment, since the ceiling surface and the floor surface are made of concrete containing an electromagnetic shielding material, it is not necessary to provide a frame structure on the ceiling surface and the floor surface. In the second embodiment, assuming that the ceiling surface and the floor surface are made of ordinary concrete and are not shielded against electromagnetic waves, a frame structure for electromagnetic shielding is arranged on the ceiling surface and the floor surface. It is set.

  The form before connecting a connection board to a ceiling surface and a floor surface is the same as the above-mentioned 1st embodiment. That is, after the frame structure shown in the first embodiment was formed, the connection plate 4 was connected to the ceiling surface and the floor surface vertically and horizontally. The connection of the connection plate 4 with the upper and lower runners 1 and 2 and the connection of the connection plates 4 were performed by spot welding. The connection plate 4 was fixed to the ceiling surface and the floor surface with concrete nails.

  The length of the diagonal line of the rectangular area partitioned by the connection plate 4 and the connection plate 4 is set to be the wavelength of the electromagnetic wave to be shielded. Similarly, the length of the diagonal line of the rectangular region partitioned by the upper runner 1 and the connection plate 4 and the length of the diagonal line of the rectangular region partitioned by the lower runner 2 and the connection plate 4 are the electromagnetic waves to be shielded. It is set to be the wavelength of.

  According to the second embodiment of the present invention, since the upper and lower runners, studs, and connecting plates constituting the frame structure can be manufactured with high accuracy in the factory in advance, the upper and lower runners and studs are assembled at the site. Make a frame, or attach a connecting plate if necessary, make it at the factory, erect this partial frame on the site and install the upper and lower runners according to the ink line, By installing the connection plate, a frame structure that realizes an electromagnetic shielding space at a regular position with high accuracy and low cost is formed.

  The effect obtained in the second embodiment of the present invention is the same as the effect obtained in the first embodiment of the present invention.

(Third embodiment)
FIG. 9 is a schematic perspective view for explaining a third embodiment of the partition frame structure of the present invention. In the first embodiment and the second embodiment, if the radio wave to be electromagnetically shielded is the same as the radio wave used in the mobile phone, the mobile phone cannot be used in this shielded space. Therefore, a state in which a mobile phone repeater is installed in the shielded space so that the mobile phone can be used in the shielded space is shown.

  The internal configuration of the repeater 9 is not particularly limited as long as it can receive radio waves from a mobile phone and transmit the received radio waves. The repeater 9 has an external antenna 9a and an internal antenna 9b for receiving and transmitting radio waves, and the antennas 9a and 9b are installed inside and outside the shielding space. Radio waves from the outside of the shielded space are received by the external antenna 9a installed outside the shielded space, and transmitted to the inside of the shielded space via the repeater 9 by the internal antenna 9b installed inside the shielded space. Received by a mobile phone. Similarly, a radio wave transmitted from a mobile phone inside the shielded space is received by the internal antenna 9b installed inside the shielded space and shielded by the external antenna 9a installed outside the shielded space via the repeater 9. Radio waves are transmitted outside the space. In this way, other mobile phones or repeaters outside the shielded space can communicate with the mobile phone inside the shielded space.

(Fourth embodiment)
FIG. 10 is a schematic perspective view for explaining a fourth embodiment of the partition frame structure of the present invention. In the first embodiment, the second embodiment, and the third embodiment, the upper and lower runners 1, 2, the stud 3, and the connection plate 4 are used for electromagnetic shielding. In this embodiment, instead of the connection plate 4, a wire mesh 4a is used. If the wire mesh 4a has conductivity, the thickness of the wire constituting the wire mesh, the mesh pattern, the shape of the mesh, the welding method of the portion where the wire and the wire intersect when forming the mesh, etc. It doesn't matter. Therefore, a fence net, a wire mesh, a bar mesh, or a punching metal may be used. It should be noted that the surface of the metal mesh may be painted or the like, but it is necessary to peel off the coating of the portion that electrically connects the upper and lower runners 1 and 2 and the stud 3.

  However, as the size of the mesh, the longest length of straight lines connecting the corners is equal to the wavelength of the electromagnetic wave to be shielded. If the mesh is circular, its diameter is used, and if it is elliptical, its major axis diameter is equal to the wavelength of the electromagnetic wave to be shielded. For example, by setting the length of the diagonal line of the mesh (the longest if long and short) to 12.5 cm, radio waves with a frequency of 2.4 Ghz can be shielded.

  In the present embodiment, the ceiling surface and the floor surface are made of concrete including an electromagnetic shielding material. Therefore, it is not necessary to consider leakage or intrusion of radio waves from the ceiling surface and the floor surface. The wire mesh 4a can be attached along the stud 3 after the upper and lower runners 1 and 2 are attached to the ceiling surface and the floor surface, respectively. When the conductive wire mesh 4a is attached to the stud 3 and the upper and lower runners 1 and 2, the upper and lower runners 1 and 2, the stud 3, and the wire mesh 4a are electrically connected. For securing the wire mesh 4a and the stud 3, and securing the wire mesh 4a and the upper and lower runners 1 and 2, an appropriate method such as bolting or welding using an auxiliary jig (not shown) can be used. The connection between the upper runner 1 or the lower runner 2 and the steel frame inside the building may be before or after the wire mesh 4a is attached.

  According to the fourth embodiment of the present invention, since the upper and lower runners, studs, and wire mesh that constitute the frame structure can be manufactured with high precision in the factory in advance, the upper and lower runners and studs are assembled on site to assemble the partial frame. By installing the upper and lower runners in line with the inking line, and then attaching the wire mesh, the electromagnetic shielding space can be realized at the correct position with high accuracy and low cost. A frame structure is formed.

  The effect obtained in the fourth embodiment of the present invention is the same as the effect obtained in the first embodiment of the present invention.

(Fifth embodiment)
FIG. 11 is a schematic perspective view for explaining a fifth embodiment of the partition frame structure of the present invention. In the fourth embodiment, after the four surfaces except the ceiling surface and the floor surface are electromagnetically shielded, wire meshes are also arranged on the ceiling surface and the floor surface. Attachment of the wire mesh to the ceiling surface and the floor surface may be performed using an auxiliary jig or the like as necessary. However, the wire mesh installed on the ceiling surface and the floor surface is electrically connected to the upper and lower runners. When the shielded space is constructed in this way, electromagnetic waves do not enter from the six sides of the shielded space and do not leak from this shielded space. The wavelength of the electromagnetic wave that does not penetrate or leak is not less than the length of the diagonal line of one mesh of the wire mesh (the longer one if longer or shorter). If the electromagnetic shielding radio wave and the radio wave used in the mobile phone are the same, the mobile phone cannot be used in this shielded space. Therefore, a state in which a mobile phone repeater is installed in the shielded space so that the mobile phone can be used in the shielded space is shown.

  The internal configuration of the repeater 9 is not particularly limited as long as it can receive radio waves from a mobile phone and transmit the received radio waves. The repeater 9 has an external antenna 9a and an internal antenna 9b for receiving and transmitting radio waves, and the antennas 9a and 9b are installed inside and outside the shielding space. Radio waves from the outside of the shielded space are received by the external antenna 9a installed outside the shielded space, and transmitted to the inside of the shielded space via the repeater 9 by the internal antenna 9b installed inside the shielded space. Received by a mobile phone. Similarly, a radio wave transmitted from a mobile phone inside the shielded space is received by the internal antenna 9b installed inside the shielded space and shielded by the external antenna 9a installed outside the shielded space via the repeater 9. Radio waves are transmitted outside the space. In this way, other mobile phones or repeaters outside the shielded space can communicate with the mobile phone inside the shielded space.

(Sixth embodiment)

In the first embodiment, the second embodiment, and the third embodiment, the upper and lower runners 1 and 2, the stud 3, and the connection plate 4 are used for electromagnetic shielding, and the fourth embodiment. In the fifth embodiment, the wire net 4a is used in place of the connection plate 4. In the sixth embodiment, a metal foil 4b is used instead of the connection plate or the wire mesh. If this metal foil 4b has electroconductivity, the thickness and material will not ask | require. Accordingly, aluminum foil, stainless steel foil, or the like can be used.

  The metal foil 4b can be attached along the stud 3 after attaching the upper runner 1 and the lower runner 2 to the ceiling surface and the floor surface, respectively. For attaching the metal foil 4b to the stud 3, a normal adhesive or the like can be used as appropriate. In this case, almost all electromagnetic waves are shielded by the metal foil 4b. Therefore, the space | interval of the stud 3 may be arbitrary and when the space | interval between the stud 3 and the stud 3 is too wide, a metal plate etc. may be installed suitably and it may affix with the metal foil 4b along it.

  According to the sixth embodiment of the present invention, since the upper and lower runners, studs, and wire mesh that constitute the frame structure can be manufactured with high precision in the factory in advance, the upper and lower runners and studs are assembled on site to assemble the partial frame. By standing up this partial frame on the site, installing the upper and lower runners in line with the ink lines, and then pasting metal foil, the electromagnetic shielding space can be created at a regular position with high accuracy and low cost. The frame structure to be realized is formed.

  The effect obtained in the sixth embodiment of the present invention is the same as the effect obtained in the first embodiment of the present invention. In the sixth embodiment, if the electromagnetic wave to be electromagnetically shielded is the same as the radio wave used in the mobile phone, the mobile phone cannot be used in this shielded space. Therefore, in order to make it possible to use a mobile phone in the shielded space, a repeater 9 may be installed in the shielded space, as in the third and fifth embodiments (see FIG. Not shown).

  In this case, the internal configuration of the repeater 9 is not particularly limited as long as it can receive the radio wave of the mobile phone and transmit the received radio wave. The repeater 9 has an external antenna 9a and an internal antenna 9b for receiving and transmitting radio waves, and the antennas 9a and 9b are installed inside and outside the shielding space. Radio waves from the outside of the shielded space are received by the external antenna 9a installed outside the shielded space, and transmitted to the inside of the shielded space via the repeater 9 by the internal antenna 9b installed inside the shielded space. Received by a mobile phone. Similarly, a radio wave transmitted from a mobile phone inside the shielded space is received by the internal antenna 9b installed inside the shielded space and shielded by the external antenna 9a installed outside the shielded space via the repeater 9. Radio waves are transmitted outside the space. In this way, other mobile phones or repeaters outside the shielded space can communicate with the mobile phone inside the shielded space.
