Description

A kind of Aseismic Steel Structures node component
Technical field
The utility model relates to long strands field, particularly relates to a kind of Aseismic Steel Structures node component.
Background technology
In modern building, often steel work can be used.Steel work compared with other is built, in use, design, construction and mixed economy aspect all there is advantage, cost is low, can move at any time.Be in particular in: steel house can better meet the requirement of architectural large bay flexible isolation than traditional architecture, and by the section area that reduces post with use Light trabs, improve area utilization rate, indoor effective usable floor area improves about 6%.Good energy-conserving effect, body of wall adopts the standardized C-type steel of light energy-saving, square steel, sandwiched plate, good heat insulating, and seismic degree is good, and energy-conservation 50%.Steel structure system is used for housing construction can give full play to the ductility of steel work, its plastic deformation ability is strong, there is excellent seismic wind resistance, substantially increase the security reliability of house.Especially, when meeting with earthquake, typhoon disaster, steel work can avoid the collapsing property of building to destroy.Building lower overall weight, system of steel residential structure, from heavy and light, is about the half of concrete structure, can greatly reduce foundation cost.Environment protecting is good, greatly reduces the consumption of sand, stone, ash during steel house construction, and material used is when demolishing buildings, and most of material can be used or degraded again, can not cause rubbish.Meet the requirement of housing industrialization and sustainable development, steel work is suitable for factory mass and produces, and industrialization degree is high, and can by the advanced finished product set such as energy-conservation, waterproof, heat insulation, door and window in one, complete application, will design, Systemizing production and construction in concrete project, improve the level of construction industry.Usually steel concrete can be used in construction; steel work is compared with ordinary reinforced concrete structure; the superiority such as it is homogeneous, high-strength, speed of application is fast, shock resistance is good and the rate of recovery is high; steel will exceed doubly a lot than the intensity of masonry and concrete and modulus of elasticity; therefore, under the condition that load is identical, the quality of steel beam column is light.From destroyed aspect, steel work is having moderate finite deformation omen in advance, belongs to ductile fracture structure, can find danger in advance, thus avoid; The existing advantage of steel work, also has shortcoming.Steel structure material intensity is high, and own wt is light, and compare with timber with concrete, the ratio of its density and yield strength is relatively low, thus under same stress condition, the member section of steel work is little, from heavy and light, is convenient to transport and installs, be suitable for span large, highly high, the structure that carrying is heavy.Steel toughness, plasticity is good, uniform in material, and structural reliability is high, is suitable for withstanding shocks and dynamic loading, has good anti-seismic performance.It is high that manufacture of steel structure installs mechanization degree, and steel structure member is convenient to manufacture in factory, building site is assembled.Millworkization manufacture steel structure member finished product accuracy is high, production efficiency is high, the assembled speed in building site is fast, the duration is short.
Steel work is a kind of structure that industrialization degree is the highest, steel work good seal performance, because welded construction can accomplish to seal completely, can be made tightness, and watertightness is high-pressure bottle all well, large-scale oil sump, pressure pipeline etc.; Steel work is because of its intrinsic advantage, and present factory building also adopts steel work to complete mostly.There will be a large amount of nodes in workshop steel structure, Nodes needs to be connected by node apparatus, and the quality of node apparatus directly can affect the anti-seismic performance of whole mill construction.
Publication number is CN201850654U, publication date is that the Chinese patent literature of on 06 01st, 2011 discloses a kind of steel structure node device, comprise steel column, pricncipal rafter, truss lower chord, channel-section steel, internal partition, head plate, junction plate, vertical stiffeners, high-strength bolt, it is characterized in that: at described steel column and truss connecting place by being welded to connect two sections of channel-section steels, channel-section steel is provided with high-strength bolt hole; All internal partition is welded, at every block internal partition edge welding head plate at the upper chord of truss and lower chord tip inside; At the junction plate that head plate lower weld and channel-section steel match, the reserved high-strength bolt hole identical with channel-section steel on junction plate; Weld the vertical stiffeners matched with channel-section steel with head plate both sides at junction plate; By high-strength bolt, channel-section steel is connected with junction plate.Node apparatus disclosed in this patent document, although by setting up internal partition and vertical stiffeners makes truss cross section local enhancement, but because structure design is unreasonable, whole node apparatus and steel column form one and are rigidly connected, when earthquake intensity is higher, bolt easily fractures, and cause whole node apparatus and steel column to disconnect, safety is poor.
