Friction energy-dissipating type close rib composite wall board

Abstract

The invention relates to a ribbed composite wallboard used in a ribbed structural system, which comprises a gridding cavity consisting of reinforced concrete beams and columns, wherein more than two precast light blocks are filled in the gridding cavity; the light blocks are regular block bodies made from raw materials including industrial slag, fly ash, cement perlite, quartz sand particles and the like; the size of the light blocks is matched with that of the gridding cavity which is provided with gaps allowing the light blocks to move; the light blocks are arranged in a longitudinal sequence mode, a transverse sequence mode or a longitudinal and transverse sequence mode; and the contact surfaces between the adjacent light blocks can overcome friction to perform relative movement. Through changing the number of the friction surfaces among filling materials in the ribbed composite wallboard, the ribbed composite wallboard achieves the effect of consuming earthquake energy through component changes.

Description

technical field [0001] The invention relates to a composite wallboard, in particular to a friction energy-dissipating dense-ribbed composite wallboard. In particular, this frictional energy dissipation type dense rib composite wall panel is especially suitable for components in an aseismic structure system. Background technique [0002] The acceleration of urbanization has led to population expansion and land reduction, and human survival is facing severe challenges. Buildings, as the necessary means of production and living for human survival, are also facing the challenge of innovation. In order to protect the environment, the use of clay bricks has been gradually banned. For this reason, people have accelerated the pace of research on new materials and new structures, and it has become a common consensus that energy-saving buildings and composite walls are widely used in various buildings. The development trend of building component materials is from heavy materials to ...

Problems solved by technology

[0004] However, the above-mentioned structural system still has the following defects: the densely ribbed composite wallboard only adopts a composite material called "finely ribbed composite wallboard" disclosed by the inventor in the patent application text of China Utility Model Publication No. 97242185.8. Wall panels, test results and practical use show that this kind of densely ribbed composite wall panels has a simple structure, and too little consideration is given to the changes in the structural seismic performance caused by the performance of the wall panels, and the mechanical failure of the wall panels mainly depends on the hysteresis caused by the plastic deformation of the structural materials Dissipate energy and dissipate energy, because hysteretic energy consumption is the damage energy of the structure, and the result will be serious damage to the structure; in the structural energy analysis theory, in addition to hysteretic energy consumption, the energy dissipation of damping energy in the structure The capacity should be exerted, and the damping energy dissipation will not cause structural damage

In addition, the filler in the composite wallboard adopts silicate blocks, because the single filler cannot meet the selection requirements of building materials in different regions
