[Warehouse industry / Class 1 warehouse] Regarding the strength of the outer wall of the opening

Hello. This is Awata from the Nagoya branch.

One of the facility equipment standards for a Class 1 warehouse is "exterior wall strength."

The strength of the frame, outer wall, or load must meet the standards set by the Minister of Land, Infrastructure, Transport and Tourism.

Excerpt from Article 3-4, Paragraph 2, Item 2 of the Warehousing Business Act Enforcement Regulations

The "standard established by the Minister of Land, Infrastructure, Transport and Tourism" mentioned here is 2,500N/mXNUMX, but how does the Transport Bureau examine facilities and equipment in practice?

This is stated in the ``Warehouse Business Law Enforcement Regulations, etc. Operation Policy''.

According to Operation Policy [4] 2-3(1), if there is a window or other opening in the exterior wall, and the width and height are both 1 m or more in internal dimension, the area where the opening is located is not recognized as an exterior wall with sufficient strength.

Therefore, it is necessary to demonstrate that it has sufficient strength using one of the following methods.

• Reinforce with base plate, square timber, etc.
• protect with iron bars
• Install fittings of JIS standard S-6 grade or higher

Around hereArchitects and designers are often misunderstood.It's a part.

We have received questions like this in the past, but there is a possibility that you will not be able to register your business as a warehouse business.

• Since it's made of reinforced concrete, isn't the exterior wall strength sufficient?
• Is it not possible to obtain permission if the glass part is changed from "tempered glass" to "wired glass"?
• If there is a reinforcing material for the window frame, is there no need to reinforce the window (glass part)?

There are some differences between the Building Standards Act, which is the specialty of first-class architects, and the Warehouse Business Act, which is the standard for registering as a commercial warehouse.

If deficiencies under the Warehousing Industry Act are discovered after design,Extra construction costs and delays in warehousing business registration, so you need to be careful.
