Description

A kind of steel structure node member
Technical field
The utility model relates to steel work technical field, relates in particular to a kind of steel structure node member.
Background technology
Steel work is compared with other construction, and in use, design, construction and mixed economy aspect all have 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 can, by reducing the section area of post and using Light trabs, improve area utilization rate, indoor effective usable floor area improves approximately 6%.Good energy-conserving effect, body of wall adopts the standardized C shaped steel of light energy-saving, square steel, sandwiched plate, good heat insulating, seismic degree is good, and energy-conservation 50%.Ductility, its plastic deformation ability that steel structure system can be given full play to steel work for housing construction are strong, have good seismic wind resistance, have greatly improved the security reliability of house.Especially in the situation that 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.Speed of application is fast, and the duration at least shortens 1/3rd, 1000 square meter than traditional dwelling house system only needs 20 days, five workmans to complete.Environment protecting is good, and steel house when construction has greatly reduced the consumption of sand, stone, ash, material used in the time of demolishing buildings, most of material can be again with or degraded, can not cause rubbish.Meet the requirement of housing industrialization and sustainable development, the suitable factory mass of steel work is produced, and industrialization degree is high, and can be by advanced finished product set such as energy-conservation, waterproof, heat insulation, door and windows in one, complete application, will design, Systemizing production and construction in concrete project, improve the level of construction industry.In construction, conventionally can use steel concrete; 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 identical condition of load, the quality of steel member is light.From destroyed aspect, steel work is to have moderate finite deformation omen in advance, belongs to ductile fracture structure, can find in advance danger, thereby avoid; Therefore, present factory building adopts steel work to complete mostly.
In workshop steel structure, there will be a large amount of nodes, Nodes need to connect by node apparatus, and the quality of node apparatus directly can affect the anti-seismic performance of whole mill construction.
Publication number is CN 201850654U, the Chinese patent literature that open day is 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: by being welded to connect two sections of channel-section steels, on channel-section steel, be provided with high-strength bolt hole at described steel column and truss connecting place; Internal partition is all welded in upper chord and inner side, lower chord end at truss, at every internal partition edge welding head plate; The junction plate matching at the welding of head plate bottom and channel-section steel, the reserved high-strength bolt hole identical with channel-section steel on junction plate; Weld at junction plate and head plate both sides the vertical stiffeners matching with channel-section steel; By high-strength bolt, channel-section steel is connected with junction plate.
