Description
Technical field
The present invention relates to long strands field, more particularly to a kind of steel structure node component.
Background technology
Steel house can better meet the requirement of architectural large bay flexible isolation than traditional architecture, and can be by subtracting
Lack the area of section of post and use Light trabses, improve area utilization rate.And good energy-conserving effect, wall use light energy-saving mark
The C-type steel of standardization, square steel, battenboard, good heat insulating, seismic degree are good.Steel structure system can fully be sent out for residential housing
It is strong to wave ductility, its plastic deformation ability of steel construction, there is excellent seismic wind resistance, the safety for substantially increasing house can
By property.Especially in the case where meeting with earthquake, typhoon disaster, steel construction can avoid the collapsing property of building from destroying.Building is total
Heavy and light, system of steel residential structure can greatly reduce foundation cost from the half of heavy and light, about concrete structure.Environment protecting
Good, steel house greatly reduces the dosage of sand, stone, ash when constructing, material used is in demolishing buildings, most of material
Material can be used or degraded again, will not cause rubbish.
The suitable factory mass production of steel construction, industrialization degree is high, and can be by energy-conservation, waterproof, heat-insulated, door and window etc. first
Enter finished product collection together in one, complete application, by design, Systemizing production and construction in concrete project, the level of raising construction industry.Lead in construction
Armored concrete can be often used, steel construction is compared with ordinary reinforced concrete structure, and its is homogeneous, high-strength, speed of application is fast, antidetonation
Property the superiority such as good and rate of recovery height, steel than the intensity and modulus of elasticity of masonry and concrete to be higher by it is many again, therefore in load phase
With under conditions of, the light weight of steel member.From the aspect of destroyed, steel construction is that have moderate finite deformation omen in advance, belongs to and prolongs
Property destroy structure, danger can be found in advance, so as to avoid；The existing advantage of steel construction, also there is shortcoming.Steel structure material intensity
Height, own wt is light, and compared with concrete and timber, the ratio of its density and yield strength is relatively low, thus equally by
The member section of steel construction is small under the conditions of power, from heavy and light, is readily transported and installs, big suitable for span, and height is high, carries the knot of weight
Structure.Steel toughness, plasticity is good, uniform in material, and structural reliability is high, suitable for withstanding shocks and dynamic load, has good anti-
Shock stability.Manufacture of steel structure installation mechanization degree is high, and steel structure member is easy to assembled in factory's manufacture, building site.Millwork
Change manufacture steel structure member finished product accuracy height, production efficiency is high, building site assembled speed is fast, short time limit.
Steel construction is a kind of structure of industrialization degree highest, steel construction good seal performance, because welding structure can be done
To being fully sealed, air-tightness, the good high-pressure bottle of watertightness, large-scale oil sump, pressure pipeline etc. can be made；Steel construction because
The advantages of its is intrinsic, present factory building are also completed using steel construction mostly.Substantial amounts of node, node occur in workshop steel structure
Place needs to be attached by node apparatus, and the quality of node apparatus can directly influence the anti-seismic performance of whole mill construction.
Publication No. CN 201850654U, publication date are that the Chinese patent literature of on 06 01st, 2011 discloses one kind
