[0012] 2) Energy absorption unit and wood structure are fixed through the occlusion of body block, avoid the traditional reinforcement method such as nailing, gluing, punching, guarantee the integrity of wood structure;

[0013] 3) Through the occlusion of energy absorption unit and wood structure body block, the stability of wall is ensured, when the building whole meets the relatively serious earthquake action, can make wood structure and wall separate, avoid the secondary injury caused by wood structure destroying wall and leading to wall collapse;

[0014] 4) The self-tapping screw is fixed at each overlap of light steel framework, forms multiple stress concentration points, makes the stress distribution of structure system more dispersed, better absorbs internal force in system, and resolves the action force of earthquake;

[0015] 5) The light steel structure with better material performance is used to replace the traditional masonry structure, so that the wall has higher anti-seismic upper limit in the earthquake, and the main material in the wall is light steel, thermal insulation filling material, board and other light materials, and different from the characteristics of masonry block falling when collapsing, the light steel wall and board will be damaged in bending, deformation and other states, so the secondary damage is smaller under the action of earthquake.
