Problems solved by technology

Light-weight panels have been developed following the requirements of the national construction industrialization, but there are still two problems: (1) the use of pure concrete wall panels contributes too much to the lateral stiffness of the structure, and there is no pre-preparation around the wall panels. Leaving seams makes the wall panels prone to damage during earthquakes; (2) The seismic performance of domestic partition wall panels is still unclear, and the research on its response in earthquakes is not very sufficient. Scholars at home and abroad have conducted a large number of wall panels. However, the research is mainly from the perspective of "hard resistance" to improve the seismic performance of wall panels, and there are few studies on the use of energy dissipation and shock absorption technology to improve the seismic performance of wall panels
[0006] 1. Only rely on the viscoelastic layer set between two adjacent masonry units and between the masonry unit on the uppermost layer and the upper frame beam, and between the masonry unit on the lowermost layer and the lower frame beam to provide damping, so Very limited ability to absorb and dissipate seismic energy;
[0007] 2. The masonry is composed of several masonry units vertically, so it is not convenient to install doors or windows on the infill wall. Once the installed door or window spans more than two masonry units, its damping and anti-seismic properties will disappear;
[0008] 3. One end of the masonry unit and the frame column are fixed and connected together with steel bars, so it is not convenient for on-site assembly and construction

Embodiment 1

[0049] This embodiment provides an assembled energy-dissipating and shock-absorbing filling wall panel structure, such as figure 1 -9, wherein the wall panel structure is located inside the frame surrounded by the upper frame beam 1, the lower frame beam 2, and the frame column 3, which includes the first vertical plate 4, the second vertical plate 5, and the first guide groove 6. Second guide groove 7, energy-dissipating anchor 8, waterproof insulation layer 9, structural joint 10, upper sliding joint 11, lower sliding joint 12, fixing piece 13, L-shaped angle steel 14, L-shaped guide plate 15.

[0050] Among them, the span of the frame is 4200mm, the floor height is 3300mm, the section size of the frame column is 500mm×500mm, the section size of the frame beam is 300mm×500mm; the concrete strength grade is C30; -2010) and "Code for Seismic Design of Buildings" (GB50011-2010).

[0051] Such as figure 1 -3, the fixed end of the first vertical plate 4 is fixedly connected to ...

Embodiment 2

[0058] The difference between this embodiment and embodiment 1 is that, as Figure 10 As shown in -12, the energy-dissipating anchors 21 in this embodiment are three rows of steel rods vertically passing through the waterproof and thermal insulation layer. The number of steel rods in each row is 7, which are evenly arranged, and there is a ring in the middle of the steel rods groove, and the groove bottom of the groove is arc-shaped.

Abstract

The invention provides an assembly energy dissipation and vibration reduction filling wall board structure. The wall board structure is located in a space defined by an upper frame beam, a lower framebeam and frame columns, and comprises a concrete board and a plurality of energy dissipation anchoring parts. The concrete board comprises a first vertical board body and a second vertical board body, the fixed end of the first vertical board is fixedly connected with the lower frame beam, and the free end of the first vertical board body is slidably connected with the upper frame beam. The fixedend of the second vertical board body is fixedly connected with the upper frame beam, and the free end of the second vertical board body is slidably connected with the lower frame beam. A waterproofheat preservation layer is arranged between the first vertical plate body and the second vertical plate body. The multiple energy dissipation anchoring parts penetrate through the waterproof heat preservation layer, and the two ends of each energy dissipation anchoring part are connected with the first vertical board body and the second vertical board body correspondingly. The assembly energy dissipation and vibration reduction filling wall board structure is simple in structure, convenient to assemble, and improves the construction efficiency. When the upper frame beam and the lower frame beam generate relative displacement, the energy dissipation anchoring parts which are fixedly connected with the first vertical board body and the second vertical board body can generate plastic deformation, then the earthquake energy is absorbed and dissipated, and accordingly the energy dissipation and vibration reduction effects are good.

Description

technical field [0001] The invention relates to an assembled energy-dissipating and shock-absorbing filling wallboard structure. Background technique [0002] In the existing prefabricated concrete structures, masonry infill walls and lightweight wall panels are the most widely used enclosure components, but in previous earthquakes, masonry infill walls were severely damaged, so that the International Society for Earthquake Engineering and Earthquake Engineering The research center regards the concrete structure of the masonry infill wall as a "high-earthquake high-risk structural system", and calls on the engineering circles of all countries to increase their awareness and attention to the seismic weaknesses of this structural system. During the earthquake, a large number of masonry infill walls were severely damaged, and the damage of structural components and even structural collapse caused by masonry infill walls was particularly prominent, which fully exposed the disadv...
