Description
Technical field
The invention belongs to technical field of structural engineering more particularly to a kind of modularization steel frames.
Background technology
Modularization steel-frame structure has the characteristics that high capacity, size selection are flexible, has vast potential for future development.No
It is same as common steel-frame structure, modularization steel frame is usually connected and composed by multiple modular units, and each modular unit is
The box frame being formed by connecting by frame column and Vierendeel girder；In modularization steel frame, multiple modular units in multiple rows of, multiple row,
Multilayer arranges, wherein the opposite sides face of each two adjacent modular units is bonded to each other.After connection, in modularization steel frame
Column position is four frame columns being immediately adjacent to each other of four, the upper layer frame column being immediately adjacent to each other and lower layer, totally eight frame columns；Side
Column position is two frame columns being immediately adjacent to each other of two, the upper layer frame column being immediately adjacent to each other and lower layer, totally four frame columns；Angle
Column position is piece frame column of one, upper layer frame column and lower layer.The central sill position of modularization steel frame is four and is immediately adjacent to each other
Vierendeel girder, side bar position are two Vierendeel girders being immediately adjacent to each other.Thus, form " eight columns, 16 beam " inside modularization steel frame
Connecting node, modularization steel frame side formed " four columns, eight beam " connecting node, formed in modularization steel frame side
The connecting node of " four beam of twin columns ".
How modular unit safely and reliably connected by connector by modularization steel frame, it has also become be badly in need of research
Problem.Currently, the connecting node form between modular unit mainly has corner fittings connecting node, cover plate bolt connecting node, answers in advance
Power connecting node, that beam beam connecting node connects plate node etc. with inner sleeve is several.Wherein, corner fittings connecting node, cover plate bolt connect
It is similar with three kinds of types of attachment of prestressing force connecting node to connect node, when connection, vertically by column open interior installation bolt or adopts
The mode for applying pretightning force with elongated prestressed strand connects, and horizontal direction is connected by connecting plate, but such connection shape
The vertical bonding strength of formula is weaker, causes the anti-side rigidity of modularization steel frame weaker.In beam beam connecting node, the beam of modular unit
It is attached using bolt between beam, and nothing is directly connected between modular unit column and column, connecting node intensity and rigidity are inclined
It is weak.Inner sleeve connects in plate node, is vertically welded to connect the frame column of upper and lower modular unit by inner sleeve, and horizontal direction is logical
It crosses connecting plate to be welded to connect inner sleeve, using being welded to connect the bonding strength and rigidity that ensure that node, but increase existing
The workload of field welding, site welding difficulty of construction are larger, it is difficult to ensure welding quality.In short, using above-mentioned existing node shape
The existing module steel frame of formula connection can envoy's dot due to lacking effective connection between column and column or between Liang Yuliang
There are prodigious gaps between formula center pillar and column or between Liang Yuliang, cannot the column of adjacent modular units and beam effectively be connected shape
At coupled column and combination beam, it is difficult to give full play to the combined effect of modularization steel-frame structure twin columns twin beams, when structure stress, is easy
Because the frame beam column section of node premature failure or individual module unit is surrendered too early, and structure is caused integrally to be destroyed.
Thus, a kind of simple structure and modularization steel frame easy for construction how are provided, to give full play to modularization steel
The twin columns twin beams combined effect of frame structure is a current technical problem for being badly in need of solving.
