日本住友建设会社,研制出一种由建筑物本身吸收地震波、抑制摇动的“制震壁”。经实验取得了充分数据,表明对大地震具有强大抵抗能力。它是由厚为1厘米的钢板三层至五层构成。以三层为例,将一张钢板竖起来,上端固定在梁上,下端夹在固定在混凝土地板上的两张钢板中间。这样可形成:中
Japan’s Sumitomo Construction Co., Ltd. has developed a “shock-making wall” that absorbs seismic waves and shakes itself from the building itself. Full data has been obtained through experiments and shows that it has strong resistance to large earthquakes. It consists of a three- to five-layer steel plate with a thickness of 1 cm. Taking three layers as an example, a steel plate is erected, the upper end is fixed on the beam, and the lower end is sandwiched between two steel plates fixed on the concrete floor. This can be formed:
