Abstract

The invention discloses an energy-consumption steel-frame block filled wall, relates to the field of building design and building aseismicity and particularly relates to a collaborative anti-seismic property of the steel frame and the block filled wall. The steel-frame block filled wall comprises an upper steel frame beam, a lower steel frame beam, a left steel frame beam, a right steel frame beam and a block filled wall. The steel-frame block filled wall is characterized in that vertical continuous seams are arranged between steel frame columns and the block filled wall and in the middle of the block filled wall. Slantwise built vertical bricks are arranged between the block filled wall and the upper steel frame beam, and the vertical continuous seams are filled through elastic-plastic materials, and gridding cloth is pasted outside the vertical continuous seams. The steel frame columns and the block filled wall are connected by spot welding of thin rebars and burying the ends into mortar joints of the filled wall. According to the energy-consumption steel-frame block filled wall, during the earthquake, the elastic-plastic materials at the vertical seams are subjected to elastic-plastic deformation, additional damping is provided for consuming partial seismic energy, and the structure partial elastic-plastic interlayer displacement can be prevented, so that the structure has the good deformation capacity and ductility, and elastic-plastic deformation and energy-consumption requirements under the action of earthquake are met.

Description

A kind of power consumption steel frame building block infilled wall
Technical field
The present invention relates to technical field of buildings, relate in particular to the collaborative anti-seismic performance of steel frame and building block infilled wall, specifically a kind of power consumption steel frame building block infilled wall.
Background technology
Current China steel house enclosed structure and party wall body also extensively adopt slag concrete hollow brick, Autoclaved aerated concrete blocks masonry, especially for cold district (north), Autoclaved aerated concrete blocks masonry, because of features such as it have high-strength light, thermal and insulating performance is good, fire resistance is good, cheap, progressively becomes the main selection of northern China steel work filled wall.
" infilled wall is connected with framework, can will adopt disengagement or release methods not according to designing requirement in 6.3.4 bar suggestion in < < Code for design of masonry strucres > > GB50003-2011.The method that has the appropriate to the occasion employing infilled wall of requirements for fortification against earthquake and framework to throw off ".But due to consider reliable between body of wall and framework be connected and construct on facility, between traditional infilled wall and framework, be connected being rigidly connected of nearly all adopting.
The 3rd section of 13.3.2 article regulation of < < seismic design provision in building code > > GB50011-2010 " body of wall should have reliable connection with agent structure, should be able to adapt to the relative storey displacement of agent structure different directions ".But the ductility of infilled wall is in the past all far short of what is expected compared with steel frame, most body of wall squeeze and destroys under geological process.
Infilled wall adopted and rigidly connected with being connected mostly of chassis body in the past, steel frame infilled wall structural system is under level or vertical dynamic action, do the as a whole acting in conjunction that comes, under horizontal earthquake action, body of wall is subject to the constraint of steel frame on the one hand, steel frame is subject to the support of infilled wall on the other hand, and this supporting role of infilled wall increases the early stage rigidity of structure greatly.From total, filled frame has absorbed larger geological process, and the shear strength of infilled wall is lower, therefore the destruction of infilled wall is early also more serious when earthquake.
Summary of the invention
The present invention is directed to the problem of above-mentioned existence, provide a kind of rational in infrastructure, have compared with large elastic-plastic deformation's ability, can earthquake energy, alleviate the power consumption steel frame building block infilled wall that filled wall cracking degree and easy construction cost are reasonably applicable to cold district.
The object of the invention is to solve by the following technical programs:
A kind of power consumption steel frame building block infilled wall, comprise upper steel-frame beam, lower steel-frame beam, left Steel Frame Column and the right Steel Frame Column, the building block infilled wall that form frame type structure, between described upper Steel Frame Column and building block infilled wall He in building block infilled wall, be equipped with vertical straight joint, between described building block and upper steel-frame beam, with vertical brick, tiltedly build, in described perps, fill viscoelastic material, perps band pastes insulation grid cloth outward.
Described building block infilled wall can arrange multiple tracks perps according to the rise-span ratio of body of wall.
Described Steel Frame Column is the fine steel rib section of spot welding with being connected of building block, corresponding with the mortar joint place of building block infilled wall.
Described bar diameter should not surpass 10 millimeters, and embedment length is not less than 50 times of bar diameters,
Described straight joint width is 10 ~ 50 millimeters.
Described building block comprises Autoclaved aerated concrete blocks, concrete hollow block, gypsum block, fly ash building block.
Described elastic-plastic material comprises cranny filler of polyurethane foam, polymer mortar, bouncing putty.
Described grid cloth comprises the alkaline-resisting grid cloth of plain edition and reinforced alkaline-resisting grid cloth.
The present invention has the following advantages compared to existing technology:
The present invention is by establishing perps and fill the deformability that elastic-plastic material improves himself in perps building block infilled wall, can guarantee the rigidity under normal operating condition, reduce structure lateral displacement, and when geological process, perps place elastic-plastic material produces elastic-plastic deformation, provide additional damping to consume part seismic energy, stop the part elastoplasticity relative storey displacement of structure, thereby the larger body of wall of rise-span ratio is separated into the moderate polylith body of wall Stiffness Deterioration of rise-span ratio by perps simultaneously, the consumption of realization to seismic energy, the adverse effect of minimizing to frame construction.The present invention makes structure have good deformability and ductility, meets elastic-plastic deformation and power consumption requirement under geological process.Key technology of the present invention is fairly simple, with low cost, and easy construction can be gathered materials on the spot, and is convenient to cold district and promotes on a large scale, and economic benefit and social benefit are remarkable.
