Description
Technical field
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.
Background technology
Welding is used in the construction of common steel work at the scene in a large number, not only affect speed of application but also construction quality and also be difficult to control, it is that occur recent years because the qualitative problems of construction that the Construction of Steel Structure quality causes is too numerous to enumerate, Site Welding is one of them important factor, the Site Welding quality is wayward, and environment is caused 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 cause a large amount of building wastes during building demolition.
Recent years, domestic scholars only limits to multilayer to the research of assembling type steel structure, and speed of application just slightly has minimizing, does not really realize the Fast Installation of steel work, embodies the advantage of steel work.
The prestress steel member only is used in the beam string structure at present, does not also use in high-level structure, adopts the prestress steel member as high-rise lateral resisting structure realization not to be arranged also on engineering.
Summary of the invention
The object of the invention is to overcome the defects of existing engineering, a kind of structural system of many, high-rise steel structure rapid construction is provided, this structural system can the realization body steel work and the Fast Installation of prestressed member, and can resist high-intensity earthquake, ideally embody 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 prestressing force eccentrical braces, comprises main body grillage 1 and the pillar system that is comprised of pillar and post cover plate, prestressing force supporting member 2; The main body grillage comprises: basic grillage and floor 15;
Described main body grillage 1 is made of the elementary cell that A, B, three kinds of basic grillages of C form, and wherein A basis grillage is the basic grillage of edge, and B, C two foundation slabs are the grillage in centre position, and B, C basis grillage alternately connects;
In three kinds of basic grillages, the beam with other adjacent one side of basic grillage is not wide beam 3; Be narrow beam 4 with the beam on other adjacent one side of basic grillage; The deck-siding of narrow beam is 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, all is 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; At least be furnished with the connection channel-section steel 10 in 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 the girder truss two ends; Be welding between the top-bottom chord of girder truss, web member, connection channel-section steel, the end-plate;
Orthogonal two beams in A, B, three 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 the 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 that forms for wide beam 3 and narrow beam 4, the interposition of A grillage is equipped with two narrow beams 4 that link to each other side by side, and two narrow beams link together with the connection channel-section steel that bolt will be in two beam same positions; 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, C basis grillage is the basic grillage of two kinds of rectangles of 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 the column base flange is wider than or equals the twice of narrow beam deck-siding, so narrow beam with after the center line of column base flange aligns, with regard to so that the column base protrusion is connected to the column base both sides, the width of half column base in long limit that is comprised of narrow beam; Node 5 is L shaped, and wherein column base and an orthogonal wide beam, a narrow beam link together with bolt, and one in wide beam and the column base flange in orthogonal two center lines is alignd; Narrow beam aligns with in two center lines another, because the deck-siding of narrow beam is less than or equal to column base flange width half, so column base also can protrude the width of half column base in long limit that is comprised of narrow beam; The column base that is B basis grillage node 5, node 6 places protrudes half column base of narrow beam that links to each other, 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 the centre position node is node 8, two ends are nodes 7; Node 8 is that four narrow beams form, wherein two narrow beam conllinear; Other two narrow beams are positioned at grillage centre position, C basis, side by side connection and vertical with the narrow beam of conllinear; The narrow beam of two conllinear respectively with the non-conterminous long limit vertical alignment of narrow beam side by side; Node 7 is that an orthogonal narrow beam and a wide beam form; Long limit, the inboard of narrow beam and wide beam vertical alignment; Be that C basis grillage node 8, node 7 all form groove, so that the projection of node 8 grooves and B basis grillage node 5 matches, the projection of node 7 grooves and the basic grillage node 6 of B matches;
Floor 15 cast are to form integral body with basic grillage on A, B, the C basis grillage;
Prestressing force 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 the factory.Adopt bolt to be connected by flange between described column base and the described pillar.
Described prestressing force supporting member can for prestressed cable or prestressing force steel pole be connected otic placode, described otic placode is connected with described mainboard by high-strength bolt.By prior stretch-draw prestressing force cable wire or prestressing force steel pole, when horizontal force action during in structure, the horizontal force component of described prestressed cable or prestressing force lever reduce in addition negative function in the horizontal force of structure, making the relative storey displacement of structure is smaller value, satisfies the requirement of standard.
