Abstract

The invention discloses an energy dissipating and damping type multi-ribbed composite wallboard and a manufacturing method thereof, and relates to an energy-consumption wallboard which is applied to seismic fortification areas or building structures with higher requirement on seismic fortification. The composite wallboard comprises infilled bricks, reinforced concrete ribbed beams and reinforced concrete ribbed columns, wherein the reinforced concrete ribbed beams and the reinforced concrete ribbed columns form a reinforced concrete grid; the top surfaces and bottom surfaces of the infilled bricks are connected with the reinforced concrete ribbed beams in the reinforced concrete grid through concave-convex grooves and tongues, and a layer of colloidal graphite is formed therebetween; and viscous-elastic materials are arranged between the two side faces of the infilled bricks and the reinforced concrete ribbed columns. The manufacturing method comprises the following steps of: binding steel bars of the reinforced concrete grid, manufacturing templates according to groove forms, and pouring concrete for curing; respectively arranging a graphite lubricating layer and a viscous-elastic material cushion on the inner surface of the grid; and pouring the infilled bricks and curing. The invention solves the problem that the infilled bricks are cracked under small seism, so that the seismic resistance of the multi-ribbed wall is enhanced.

Description

technical field [0001] The invention is applicable to the dense rib structure system, and is a new type of energy-dissipating wall. It is suitable for seismic fortification areas or building structures with high requirements for earthquake fortification. Background technique [0002] In recent years, earthquakes have occurred frequently all over the world, which has brought huge disasters to human production and life. Seriously restricted the progress of human civilization. In particular, China is a country with a high incidence of earthquakes, coupled with its large population, densely populated houses, and low levels of earthquake resistance of houses, resulting in huge casualties and economic losses every time an earthquake strikes. In addition, with the development of new rural construction, an economical, earthquake-resistant, and fast-construction structural system is required to be suitable for the current large-scale urban and rural construction. [0003] Therefor...
