Description

  The present invention relates to a wiring and piping penetration structure that allows wiring and piping to penetrate through a concrete wall.

Conventionally, various wiring pipe penetration structures have been devised that allow wiring and piping to penetrate through a concrete wall of an architectural civil structure.
However, any wiring and piping penetration structure is airtight, moisture-proof and waterproof, earthquake-resistant, rigid, explosion-proof, fire-proof, heat-resistant, shielding, electromagnetic shielding, sound-proofing, confidentiality and security, etc. However, it does not satisfy all the performance elements of maintainability and expandability at the same time, but tends to be formed with emphasis on any of these performance elements (see Patent Document 1), and disasters outside the expected range When a factor occurs, there is a possibility that the wiring pipe penetration structure is damaged in some way and the space separation property is impaired.

The space separation defined in the previous section is defined as indicating the degree of physical interference in the space divided by the walls, excluding the wiring pipes that physically interfere with each other. The high performance means that the degree of physical interference in the portion excluding the wiring pipes that physically interfere with each other is small and ideal.

In addition, in any wiring piping penetration structure, if the wiring piping must be replaced due to aging / damage of the wiring piping, or if new wiring piping is added / changed, When a part of the wall body needs to be demolished, there is a tendency that it is not an effective structure for maintainability and expandability.

  The possibilities and trends mentioned above are due to the fact that the existing wiring and piping penetration structure satisfies limited performance factors and was devised in pursuit of functionality / dedicated / economical, etc. specialized for the purpose of use. I think that.

For this reason, in structures such as nuclear shelters that must maintain high spatial separation and ensure disaster prevention protection against destructive elements from the outdoors, they are airtight, moistureproof and waterproof, earthquake resistant, rigid, Explosive, fire-proof, heat-resistant, shielding, electromagnetic shielding, soundproofing, security and confidentiality are simultaneously protected to protect the interior safely, and maintainability required for operation management in a long standby period However, it is desirable to ensure the expandability such as the addition / change of wiring pipes that are newly required as the times change, but none of the conventional wiring pipe penetration structures can satisfy these conditions. In the event of a disaster, there is a high possibility that an adverse effect will be transmitted to the indoor side through the wiring pipe penetrating structure, and it is considered that uneconomical work must be performed during maintenance or expansion.
