Device energy-wasting type multi-ribbed composite wallboard

Abstract

A multi-ribbed composite wall for a multi-ribbed structure system comprises a frame formed by profile steels, profile steel concrete, reinforced concrete beams and posts, wherein the frame is divided into a plurality of grids by cross sections and dividing strips of the profile steels with less bearing capacity, the profile steel concrete and reinforced concrete so as to form grid cavities; damping devices are relatively filled into the grid cavities according to the bearing capacity of the profile steels, the profile steel concrete, the reinforced concrete beams and the posts; and each damping device comprises a plurality of miniaturized dampers, and the like. The invention increases the earthquake energy consumed by components by additionally installing the small-sized damping devices.

Description

technical field [0001] The invention relates to a composite wall structure, in particular to a device energy-consuming composite wall. In particular, this composite wall structure is especially suitable for load-bearing wall elements in earthquake-resistant structural systems. 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. 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 light materials, from block materials to plate materials, and from single materials to composite materials. With the ...

[0007] However, the densely ribbed composite wallboard only adopts a kind of composite wallboard called "finely ribbed composite wallboard" disclosed by the inventor in the patent application text of China Utility Model Publication No. 97242185.8. The test results and practical use It shows that the structure of this kind of densely ribbed composite wallboard is simple, and there is too little consideration for the change of the structural seismic performance caused by the performance of the wallboard. The return energy 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 the hysteretic energy dissipation, the energy dissipation capacity of the damping energy in the structure should be brought into play, and the damping energy Can not cause structural damage, the energy dissipation performance of composite wall panels has not yet been developed, and the understanding of the structure is still relatively lacking, which limits the use of composite wall panels as energy-dissipating components

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

Furthermore, the ribbed composite wallboard has a single function, and needs to be improved in terms of sound insulation, heat insulation, fire prevention, and waterproof performance.
