Research and improvement, successively propose diagonal strip model, pull rod-equivalent gusset model, multi-angle pull rod model, correct brace mould
Type, orthotropic Slab, mixing member system model, unification etc. are for model etc..But its basic principle is to assume in the design
Steel plate shear force wall is solely subjected to lateral load, is simplified to cross-brace construction, and determine according to the equivalent principle of lateral rigidity
Supporting section size.Equal stiffness before flexing occurs with steel plate shear force wall for the rigidity of cross-brace construction, is checked by software
The structural internal force.
It is thin that currently used steel plate shear force wall is generally divided into non-ribbed stiffener steel plate wall, stiffening rib steel plate wall, non-ribbed stiffener
Board wall, both sides crack steel plate wall, pressure-type steel plate wall etc., but existing pure steel plate shear force wall still suffers from some problems in the application, such as
Steel plate steel using amount is big；Sheet metal easily there is out-of-plane deformation and weld there are residual stress and defect, ribbed stiffener easily generation office
The technical barriers such as correlation computations formula comparison is complicated in portion's flexing, specification, steel plate wall transport and in-site installation are more difficult.In addition,
Spatial mesh structure is widely used in various middle long-span space knots because of its component and node easy to batch production manufacture, assembling installation
In structure, and there is preferable stress performance.
The content of the invention
The present invention provides a kind of grid type steel plate shear force wall for technical problem present in solution known technology and its should
The shear wall system of shear wall system, the shear wall and its application, which can be realized, to be saved material, avoids out-of-plane deformation, reduces
Residual stress, simplified model analysis, raising industrialized level, quickening speed of application, development assembling type steel structure are built outside face
Purpose.
The present invention is for a technical solution being taken of technical problem present in solution known technology：A kind of grid type

Leverage simplified mathematical model basic principle is mixed to set.
The rod piece of the spatial mesh structure is using made of steel pipe.
The steel pipe is round steel pipe or square steel tube.
The node of the spatial mesh structure is welded spherical node or bolted spherical node or tubular joint.
The rod piece diagonal cross of the spatial mesh structure is set.
Horizontally disposed another part of a rod piece part of the spatial mesh structure is vertically arranged.
The present invention is for another technical solution for being taken of technical problem present in solution known technology：One kind uses
The grid type steel plate shear force wall system of above-mentioned grid type steel plate shear force wall, the grid type steel plate shear force wall are adopted with girder steel and steel column
It is affixed with connecting node.
The girder steel and the steel column use H profile steel component, are formulated with pairs in the web both sides of the H profile steel component
Floor.
The present invention has the advantages and positive effects of：
1) grid type steel plate shear wall structure theoretical based on steel plate shear force wall mixing leverage simplified mathematical model and proposition,
On the premise of Accuracy and high efficiency is ensured, process of calculation analysis has obtained very big simplification, its difficulty in computation and it is time-consuming all
A degree of reduction is obtained；2) existing steel plate shear force wall welding deformation is big, and residual stress is big, site operation welding job
Amount is big, and site operation is difficult to install, and the present invention solves these and ask to a certain extent by using spatial mesh structure
Topic；3) existing steel plate shear wall steel using amount is big, and the present invention can reduce steel using amount by using spatial mesh structure.
4) the features such as spatial mesh structure industrialization processing, assembling installation can be made full use of, accelerate in-site installation speed, save and throw
Money；5) rod piece of grid type steel plate shear force wall and node can be prefabricated in the factory in advance, meet national development assembled architecture
Main trend.
In conclusion the present invention can solve, steel plate shear force wall steel using amount is big, out-of-plane deformation, residual stress, site operation
The problems such as difficult, and the advantages such as spatial mesh structure batch production manufacture processing, in-site installation, assembling degree height are made full use of,
Achieve the purpose that to save material, simplified model analysis, improve industrialized level, development assembling type steel structure.
