Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an electromagnetic shielding structure for the entire building.
Regarding intelligent buildings suitable for adopting information network systems using radio waves,
In particular, the present invention relates to a method for grounding a sash frame in an intelligent building where a window frame is grounded.

[Conventional technology]

Generally, in intelligent buildings, information communication equipment such as complex electronic exchanges and computers are shared to communicate information within the building and with the outside world. , Providing faster and more accurate information has become a major issue in large-scale buildings. Optical fiber is a solution to these challenges in intelligent buildings.
Information networks based on data highway methods using cables and coaxial cables have been studied and proposed.

[Problem that the invention seeks to solve]

However, with the data highway method that uses fiber optic cables and coaxial cables, the fiber optic cables and coaxial cables must be stretched to every corner of the intelligent building, and the cost and time required for laying the cables is high. It will cost extra.

Furthermore, if radio waves are used for information communication within a building, there is no need to lay cables, but in this case, on the other hand, frequencies up to 50 GHz are subject to regulations under the Radio Law, as they emit noise radio waves to the outside. On the other hand, external radio waves and internal TV intermediate frequencies,
A problem arises in that the system malfunctions due to radio waves from the wireless microphone.

Therefore, the applicant constructs the frame and openings such as windows and doorways using electromagnetic shielding members,
We have separately proposed an intelligent building that enables communication within the building using radio waves by making the entire building an electromagnetic shield structure. In this case, the entire building is electromagnetically shielded by using mesh-filled glass or glass covered with conductive film for the windows and entrances that open into the building.

By the way, when ensuring the electromagnetic shielding performance of a window using glass with a mesh or glass with a conductive film attached, it is necessary to ensure that the mesh of the window glass, the conductive film, and the window frame are grounded. . However, since ensuring electromagnetic shielding performance in conventional glass windows has not been particularly studied, even if an electromagnetic shielding layer is provided on the window glass using mesh or conductive film,
At present, the technology for specifically grounding windows using such glass has not yet been established.

The present invention is based on the above invention, and includes:
The object of the present invention is to provide a method for grounding a sash frame in an intelligent building by which the window frame can be easily grounded at low cost.

[Means for solving problems]

To this end, the method for grounding a sash frame in an intelligent building according to the present invention is characterized by establishing an earth bond between the concrete reinforcing reinforcing bars of the building frame and the sash frame.

[Effect]

In the method of grounding a sash frame in an intelligent building according to the present invention, an earth bond is established between the concrete reinforcement reinforcing bars of the building frame and the sash frame. The sash frame can be easily grounded without being exposed to the air, ensuring electromagnetic shielding performance.

〔Example〕

Examples will be described below with reference to the drawings.

Fig. 1 is a diagram for explaining one embodiment of the method for grounding a satsume frame in an intelligent building according to the present invention, and Fig. 2 is a diagram for explaining another embodiment of the method for grounding a satsume frame in an intelligent building according to the present invention. This is a diagram for In the figure, 1 and 7 are the sash frames, 2 is the sash anchor, the steps are embedded anchors, 4 and 8 are reinforcing bars, 5 is mortar, and 6 and 9 are the building blocks.

The example shown in FIG. 1 shows how to prepare an earth bond when concrete for a frame 6 is poured, a sash frame 1 is fitted, and the concrete is filled with mortar 5. First, a reinforcing bar 4 for concrete reinforcement and an earth bond are attached to the embedded anchor 3, and then the embedded anchor 3 is embedded in the concrete of the frame 6 by integral casting. Then, the sash frame 1 to the embedded anchor 3 are welded and joined at a plurality of locations via the sash anchor 2, and then filled with mortar 5. By doing so, the sash frame 1, the sash anchor 2, the embedded anchor 3, and the reinforcing bar 4 are completely electrically connected, and sufficient conductivity can be obtained.

Further, the example shown in FIG. 2 is an example in which the sash frame 7 is held by integrally driving the concrete of the frame 9. In this case, an earth bond is made by welding from the main body of the sash frame 7 to the reinforcing bars 8 for reinforcing the concrete of the frame 9. Therefore, in this case,
This eliminates the need for embedded anchors 3 as in the example shown in FIG.

Fig. 3 is a diagram showing an example of grounding a window glass through a sash; 11 is a window glass;
2 is an electromagnetic shielding layer, 13 is a conductive paint, 14 is a conductive rubber, and 15 is a sash.

In FIG. 3, a window glass 11 has an electromagnetic shielding layer 12 made of a conductive blind material such as mesh or film therein, and a conductive paint 13 is applied to the ends thereof. Conductive rubber 14
The window glass 11 is compressed and fixed to the sash 15, and this conductive paint 13, conductive rubber 1
4 electrically connects the electromagnetic shielding layer 12 of the window glass 11 to the sash 15. Therefore, the first embodiment described above as an embodiment of the present invention
As shown in the figure and Figure 2, connect the sash frame to the reinforcing bars for concrete reinforcement of the frame by attaching an earth bond, electrically connect the window glass to the sash and the sash frame, and from the sash frame to the reinforcing bars to ground the reinforcing bars. By doing so, the electromagnetic shielding performance of the window can be improved.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, since the window frame sash is electrically connected to the concrete reinforcing steel of the frame by welding and earth bonding, it has good conductivity and can improve electromagnetic shielding performance. can. In addition, since the reinforcing bars for concrete reinforcement of the building frame are used, and there is no need to lay a separate ground wire, processing can be done easily, and furthermore, the ground wire does not make it difficult to see. You can keep the appearance clean.
