Problems solved by technology

If the traditional fixed connection method is adopted, such as figure 2 As shown, the floor is forced to follow the deformation of the self-resetting wall under the earthquake action, and a reaction force constraining the relative deformation will be generated at the connection node. Once the material limit is exceeded, a large number of cracks or even damage will be caused at the connection of the floor, affecting the floor. The horizontal seismic force is transmitted to the self-resetting wall, and the restraint at the joints will also prevent the wall from swaying, thus affecting the seismic performance of the overall structure

Embodiment 1

[0044] In this embodiment, the horizontal component is the floor 2. When the self-resetting shear wall adopts an embedded arrangement, the self-resetting shear wall is adjacent to the floor, and there is deformation inconsistency between them.

[0045] Such as Figure 1-5 Shown: a connection node between a low-damage self-resetting shear wall and a horizontal member, which includes a self-resetting shear wall 1, a floor 2, and a steel connector 3;

[0046] The floor 2 is rectangular, and a groove 2-1 is vertically provided on the outside of one of the long sides;

[0047] Such as Figure 3-2 As shown: the steel connector 3 includes an upper angle steel 3-1, a lower angle steel 3-2 and a connecting rod 3-3 connected between the fold lines of the upper and lower angle steels, and the two ends of the connecting rod 3-3 are respectively Shrink inward to form an arc;

[0048] First, fix the floor 2 and the steel connector 3; place the floor 2 horizontally between the plates of t...

Embodiment 2

[0066] Such as Image 6 As shown: in this embodiment, the horizontal member is a frame beam 9, and frame columns 8 are arranged on both sides of the frame beam 9; when the self-resetting shear wall 1 adopts an external hanging arrangement or is used to The shear wall is adjacent to the frame beam 9 at the corresponding floor position, and there is deformation inconsistency between them.

[0067] The middle part of the steel connector 3 is engaged with the frame beam 9 with a reserved groove, the distance between the upper and lower angle steels is slightly larger than the height of the frame beam 9, and the vertical and rotational degrees of freedom are loosened by corresponding radian design. Its mechanism of action and construction and installation method of present embodiment and embodiment 1 are all the same.

Abstract

The invention relates to a connection node between a low-damage self-resetting shear wall and a horizontal member. The horizontal member is rectangular and has a groove on the outside; the steel connecting piece includes an upper angle steel, a lower angle steel and a connecting rod; first, the horizontal member and the steel Connectors; secondly, fix steel connectors and self-resetting shear walls; finally, fill; to prevent relative deformation due to friction at the end, in order to adapt to vertical deformation and facilitate construction and installation, plastic foam and other flexible materials are provided in the gap. filling; the present invention relaxes the rotation constraint and vertical deformation between the self-resetting shear wall and the horizontal member through a reasonable isolation design, but it has sufficient rigidity and limited degree of relaxation, so it has strong integrity and low Damage characteristics.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a connection node between a low-damage self-resetting shear wall and a horizontal member. Background technique [0002] In recent years, recoverable functional structures have become a research hotspot in the fields of structural engineering and earthquake engineering. Compared with traditional structures, recoverable functional structures have the characteristics of less damage to the main structure after earthquakes, less residual displacement, and replaceable damaged parts. The self-resetting shear wall structure is a kind of recoverable functional structure. A large number of experiments and theoretical studies have been carried out at home and abroad, and a relatively mature structural system has been formed, and relevant practical engineering applications have been abroad. [0003] The self-resetting shear wall structure is usually composed of a self-resetting wall that bea...
