A kind of industrialization assembling is many, high-rise steel structure eccentrical braces
The present invention relates to a kind of new structure system, particularly a kind of industrialization assembling type steel structure eccentrical braces of building field application.
The construction of common steel work is used welding at the scene in a large number, not only affecting speed of application but also construction quality is also difficult to control, the qualitative problems of construction causing due to Construction of Steel Structure quality occurring recent years is too numerous to enumerate, Site Welding is one of them important factor, Site Welding quality is wayward, and environment is caused to very large pollution.
Traditional reinforced concrete structure needs on-the-spot assembling reinforcement, fluid concrete, needs a large amount of artificial and curing times, and construction costs improves greatly.And when building demolition, cause a large amount of building wastes.
Recent years, domestic scholars only limits to multilayer to the research of assembling type steel structure, and just slightly minimizing of speed of application, does not really realize the Fast Installation of steel work, embodies the advantage of steel work.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect of existing engineering, a kind of structural system of high-rise steel structure rapid construction is provided, this structural system can realization body steel work and the Fast Installation of supporting member, and can resist high-intensity earthquake, ideally embodies the advantage of steel work.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of industrialization assembling is many, high-rise steel structure eccentrical braces, the pillar system, the supporting member 2 that comprise main body grillage 1 and be made up of pillar 8 and post cover plate; Main body grillage comprises: basic grillage and floor 15;
The elementary cell that described main body grillage 1 is made up of A, B, tri-kinds of basic grillages of C forms, the basic grillage that wherein A basis grillage is edge, and the grillage that B, C two foundation slabs are centre position, and B, C basis grillage alternately connects;
In three kinds of basic grillages, be not wide beam 3 with the beam on other adjacent one side of basic grillage; Be narrow beam 4 with the beam on other adjacent one side of basic grillage; The deck-siding of narrow beam is the half of wide beam deck-siding, and the deck-siding of wide beam is less than or equal to the width of column base flange; Wide beam, the structure of narrow beam is identical, is all girder truss; Wherein the top-bottom chord of girder truss, web member are channel-section steel, and web member becomes the angle of 30 degree-60 degree with chord member; The connection channel-section steel 10 that is at least furnished with 3 strap bolt holes between each girder truss top-bottom chord, respectively there is the end-plate of the rectangle in a strap bolt hole at girder truss two ends; Between the top-bottom chord of girder truss, web member, connection channel-section steel, end-plate, be welding;
Orthogonal two beams in A, B, tri-kinds of basic grillages of C, along deck-molding and two stiffeners 12 by being welded to connect; Adjacent beam connects with bolt at the connection channel-section steel of two beam same positions side by side; In basic grillage with column base 7, column base is connected with bolt with adjacent beam;
A basis grillage is basis, the outside grillage of main body grillage 1, the basic grillage of the rectangle forming for wide beam 3 and narrow beam 4, the interposition of A grillage is equipped with two narrow beams 4 that are connected side by side, and two narrow beams will link together in the connection channel-section steel of two beam same positions with bolt; The outer long side of A basis grillage is arranged pillar 8 on one side; Pillar is not arranged on the long limit adjacent with other basic grillages on one side;
B basis grillage, the basic grillage of two kinds of rectangles that C basis grillage is intermediate form; Pillar 8 is not arranged on the narrow beam limit that wherein B basis grillage is adjacent with A basis grillage; Pillar 8 is arranged on the narrow beam limit adjacent with C basis grillage, forms node, and wherein intermediate node is node 6, and the node at two ends is node 5; Node 6 is T shape, because column base flange is wider than or equals the twice of narrow beam deck-siding, so after narrow beam is alignd with the center line of column base flange, just make column base protrude the width of half column base in long limit that is connected to column base both sides, is made up of narrow beam; Node 5 is L shaped, and wherein column base and an orthogonal wide beam, a narrow beam are bolted together, and wide beam aligns with in orthogonal two center lines in column base flange one; Narrow beam aligns with another in two center lines, because the deck-siding of narrow beam is less than or equal to the half of column base flange width, so column base also can protrude the width of half column base in long limit being made up of narrow beam; The column base that is B basis grillage node 5, node 6 places protrudes half column base of narrow beam being connected, and forms a projection;
Pillar is not all arranged on C basis grillage and B basis grillage, the two long limits that A basis grillage is adjacent, the node on the long limit that C basis grillage is adjacent with B basis grillage, and centre position node is node 8, two ends are nodes 7; Node 8 is four narrow beam compositions, wherein two narrow beam conllinear; Other two narrow beams are positioned at grillage centre position, C basis, connection and vertical with the narrow beam of conllinear side by side; The narrow beam of two conllinear respectively with the non-conterminous long limit vertical alignment of narrow beam side by side; Node 7 is an orthogonal narrow beam and a wide beam composition; Long limit, the inner side vertical alignment of narrow beam and wide beam; Be that C basis grillage node 8, node 7 all form groove, make that node 8 grooves and the projection of B basis grillage node 5 match, the projection of node 7 grooves and the basic grillage node 6 of B matches;
The stub of column base 7 for being wrapped up by the column base connector 7-1 in strap bolt hole with column base flange, surrounding up and down; Each parts are by being welded together; Pillar 8 and post cover plate are by being welded together; Post cover plate, column base flange, beam are bolted together;
Floor 15 cast are, on A, B, C basis grillage, to form entirety with basic grillage;
Supporting member 2 its ways of realization are herringbone accentric support or diagonal angle accentric support.
Described steel work main body grillage comprises basic grillage, floor.In factory, described wide beam, narrow beam, floor are made of one, wide beam and narrow beam are in factory and are welded by channel-section steel.Pipeline passes through between the web channel-section steel of wide beam and narrow beam, thereby forms A basis grillage, B basis grillage and C basis grillage.At described foundation slab frame plate and described column base connecting portion, described wide beam and described narrow beam junction are with bolts and part welding only limits in factory.Between described column base and described pillar, adopt bolt to be connected by flange.
Described otic placode is connected with described mainboard by bolt.When horizontal force action is during in structure, the horizontal force component of described lateral resisting steel plate reduces even negative function in the horizontal force of structure, and making the relative storey displacement of structure is smaller value, meets the requirement of specification.
The present invention adopts the construction stage can realize quick assembled type the effective high-rise steel structure system of the horizontal sidesway of opposing.This form of structure not only can effectively realize the industrialization of steel structure member processing and can greatly improve speed of application and significantly reduce steel using amount.
Find by engineering practice and the experiment of 1:10 vibroplatform, described new structure system has improved 500% than ordinary construction system speed of application, and steel using amount reduce by 50%, and realize job site " anhydrous, without fire, dustless ", the potential safety hazard that has reduced site operation, reduces environment pollution.
