A basic design that can be done quickly and cheaply for public structures in an earthquake-prone country

 

Production of basic materials

 

A square steel plate with a side of 1 to 5 inches and a thickness of 5 mm as an example

determine the standard

Personally, I think 2 inches is a good weight for him.

In the center he drilled a hole for the bolt to go through

 

 

A welder that welds three pieces

 

Use 3 of them and combine them into triangles with the same sides on each side, then weld them together with the triangle side openings, or make triangles with a press, etc. Combine them at 60 degrees, fasten them with bolts and nuts, and create a wall, depending on the location, with plates, etc. Block it up, put soil or cement in between, and make it a wall, etc.

 

The finished product is a honeycomb-like board wall, only the edges are made of boards and steel frames to create straight lines

 

 

Parts can be mass-produced with simple workSince they are simple products, they can be manufactured in any country

If you make it cheaper, I think the standard should be a few inches on one side, but he also specified centimeters.The bolt is from that country

His panel only determined by the general standard of inch bolt core diameter is about 1 cm

 

The screw is a standard nut, and only the thickness of the iron plate and the width of the nut are required.

 

The triangular iron parts are provided by countries other than the victim

bolts and nuts

 

The finished triangle and he sent bolts and nuts to Japan and abroad

 

Steel columns are transported by ship, but the recipient country may not necessarily have machine tools

 

 

 

Anyone can assemble a wall alone.

External reinforcement later with wood or steel frame

The board that sandwiched it and he put cement in the gap to make it a base

 

Parts can be transported even if it's not a big dump truck.

地震の国の　公共構造物　早く　安くできる基本設計

 

基本材料の制作

 

一辺　1から5インチの　正方形　鉄板　厚みは　例として5ミリとする

規格を決める

　個人的には2インチが　いいと思う　重量とか考えで

中心に　ボルトが通る穴を開けておく

 

 

3枚を溶接する溶接機

 

それを　3枚使用して　三角形　各面同じで合わせて　三角横空きでじしんの　溶接する または　プレスなどで三角を作っておく　各６０度　それを組み合わせ　ボルト・ナットで止め　壁を作る　場所により　板などで塞いだり　間に土またはセメントを入れ　壁などとする

 

出来上がりは　想定　蜂の巣のような　板壁　端のみ　板や　鉄骨で　直線を作る

 

 

部品は　簡単作業で大量に作れる　単純製品であるのでどこの国でもできる

作れば安くなる　規格は一緒　1辺　数インチがいいと思うが　　センチも明記　ボルトはその国

の一般規格で決まる　パネルのみインチ　ボルト芯直径は1センチぐらい

 

ネジ　ナットは規格品で　　鉄板の厚みとナットの幅のぶんしかいらない

 

三角の鉄部品は被害以外の国が提供する

ボルト・ナットも

 

できた三角と　ボルト・ナットを　日外国に送る

 

鉄柱鉄骨は　船で運ぶが　相手先　被害の国に工作機械があるとも限らない

 

 

 

壁だけでも　誰でも組み立てられる　下手したらスパナだけでもできる

外部補強は　後で木材でも　鉄骨でも

それを挟んだ　板や　その隙間にセメントを入れて　台とする

 

大きなダンプとかでなくても部品は運べる　Hこうなどと違い　　一つ一つは重くない
