Embodiment 1

[0032] Such as Figure 1-8 As shown, it includes a frame composed of frame columns 1 and frame beams 3 and a wall panel structure inside the frame. In this embodiment, the frame is a concrete frame with a span of 5400mm and a floor height of 3000mm. The cross-sectional dimensions of the left and right frame columns are both 500mm×500mm, and the cross-sectional dimensions of the top and bottom beams are both 300mm×500mm. The design strength of the concrete The grade is C30. The reinforcement of beams and columns is determined according to "Code for Design of Concrete Structures" (GB50010-2010) and "Code for Seismic Design of Buildings" (GB50011-2010).

[0033] A damping layer 5 is installed between the wall panel 4 and the frame beam 3; a flexible filler 6 is filled between the wall panel 4 and the frame column 1;

[0034] The flexible filler 6 is a PU foaming agent.

[0035] The connecting structure 7 includes a pre-embedded fixture and a connecting piece; the pre-embedded ...

Embodiment 2

[0068] On the basis of Example 1, in order to further increase the anti-seismic finishing of the wall panels, the following improvements are made: flexible fillers 6 are filled between the wall panels 4 and the frame beams and frame columns.

[0069] Wallboard 4 is a rectangular wallboard, and the rectangular wallboard includes two L-shaped sub-wallboards 41 of the same size and shape; the two L-shaped sub-wallboards 41 are rotationally symmetrically arranged with the geometric center of the rectangular wallboard; The horizontal contact interface of the sub-wall panel 41 is on both sides of the wall panel 4, and the horizontal contact interface is filled with a damping layer 5, and is connected to each other through the in-plane bending deformation energy dissipator 19 of the steel plate; the two L-shaped sub-wall panels 41 The vertical contact interface is in the middle of the wallboard 4, and the impact buffer layer 18 is fixed at the vertical contact interface, and the flexi...

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...
