Multilayer fabricated concrete wallboard structure system

Abstract

The invention provides a multilayer fabricated concrete wallboard structure system. The multilayer fabricated concrete wallboard structure system comprises a foundation, prefabricated wallboards and post-tensioned unbonded prestressed bars. The prefabricated wallboards are arranged on the foundation, at least two prefabricated wallboards are vertically spliced, and the prefabricated wallboards and the foundation are connected into a whole through the unbonded prestressed bars. One end of each unbonded prestressed bar is anchored in the foundation, and after being connected with the prefabricated wallboards in series, the unbonded prestressed bars are anchored to the ends of the prefabricated wallboards. Horizontal seam connecting pieces are arranged at the corners of the prefabricated wallboards, and the vertically-spliced prefabricated wallboards are connected and positioned through the horizontal seam connecting pieces. According to the multilayer fabricated concrete wallboard structure system, dry construction is adopted, fabrication accuracy and fabrication speed are high, and the requirement for building industrialization development is met. Because the multilayer fabricated concrete wallboard structure system has high capacity for dissipating earthquake energy, when an earthquake hazard happens, the requirement that the multilayer fabricated concrete wallboard structure system is not damaged in a small earthquake, can be recovered in a medium earthquake and does not collapse in a strong earthquake can be met, and the safety level of a multilayer fabricated building can be substantially improved.

Description

technical field [0001] The invention relates to the field of anti-seismic and shock-absorbing technology of structural engineering, in particular to a multi-layer assembled concrete wall panel structure system. Background technique [0002] The seismic performance of the prefabricated concrete structure in the prior art is achieved through the "wet connection" of the nodes to achieve the equivalent of cast-in-place. On the one hand, this will weaken the advantage of the fast construction speed of the prefabricated concrete structure system. On the other hand, it requires connection The strength and stiffness of joints or joints are large enough to prevent the failure of plastic hinges at joints. [0003] The most notable feature of the post-tensioned unbonded prestressed prestressed prefabricated concrete wall panel structure system under the action of earthquakes is that a large nonlinear displacement occurs with little or no damage, insufficient energy dissipation capacity...
