Energy dissipation and shock absorption assembly type infilled wallboard structure

Abstract

The invention discloses an energy dissipation and shock absorption assembly type infilled wallboard structure. The energy dissipation and shock absorption assembly type infilled wallboard structure comprises a wallboard, the wallboard is a rectangular wallboard, the wallboard comprises two L-shaped sub-wallboards with the same size and shape; the horizontal contact interfaces of the two L-shaped sub-wallboards are filled with damping layers and are connected with each other through a bending deformation energy dissipation device in the plane of a steel plate; and the vertical contact interfaces of the two L-shaped sub-wallboards are located in the middle of the wallboard, impact buffer layers are fixedly arranged on the vertical contact interfaces correspondingly, and the space between theimpact buffer layers is filled with flexible filler. The energy dissipation and shock absorption assembly type infilled wallboard structure is provided with different levels of energy dissipation structures, the wallboard structure has the shock absorption and energy dissipation effects under the action of small earthquakes, medium earthquakes and large earthquakes; the wallboard structure has good deformation ability, the wallboard can be effectively prevented from being damaged under the conditions of small earthquakes and medium earthquakes; and the wallboard structure can play a supporting role under the condition of large earthquakes to prevent a wall body from collapsing.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to an energy-dissipating and shock-absorbing assembled filling wall panel structure. Background technique [0002] Masonry infill walls are widely used maintenance components in frame structures, but ordinary infill walls have high rigidity, poor deformation capacity, energy dissipation capacity and integrity, and the walls are prone to cracking, even damage, and collapse under earthquake action. In addition, the infill wall will impose greater constraints on the frame structure, which will increase the rigidity of the structure and withstand greater earthquake action. In the 2008 Wenchuan earthquake, a large number of masonry infill walls were severely damaged, causing damage to the frame beam-column members connected to them, and even causing the structure to collapse, fully exposing the inadequacy of masonry infill walls in terms of earthquake resistance. These problems put fo...

[0003] The invention patent application with the publication number CN 102268900A discloses "a damping and anti-seismic filling wall panel for frame structure". The lateral stiffness of the filling wall panel is reduced compared with the traditional filling wall, and the adjacent two masonry There are viscoelastic layers between the units, between the masonry units on the uppermost floor and the upper frame beams, and between the masonry units on the lowermost floor and the lower frame beams, which can be used to dissipate the energy input by the earthquake and reduce the seismic response of the structure. But still there are following deficiencies: 1, only rely on the viscoelastic layer to provide damping, the seismic energy of dissipation is limited

2. Since one end of the masonry unit needs to be integrated with the frame column by steel bars, it is not convenient for on-site construction

3. After the masonry unit is damaged by the earthquake, it is not easy to repair quickly
