Brick and stone construction

Bricks are unit materials that can only be compressed. The traditional masonry methods for brick and stone structures include brick arches and overlapping. The brick arch structure emerged during the Northern Wei Dynasty, where brick was used to form an arched wall structure. When the arch is subjected to pressure, the force is dispersed and transmitted to the downward or outward part. Therefore, as long as the texture of the arched structure is uniform, the force it disperses and transmits will also be very uniform, making the center of gravity more stable. Stacking: refers to the arch formed by stacking layers of bricks, stones, wood, etc. inward and finally closing at the center line; If it is stacked layer by layer and protruding outward, it must bear the weight of the upper layer.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
