Description
Technical field
The present invention relates to steel performance, especially a kind of Z-shaped steel reinforced concrete special-shaped columns of supporting role's steel frame.
Background technology
Modern civilization has expedited the emergence of the transformation of people to things aesthetic standards, and as vertical supporting member---the post in frame construction, its traditional form is square-section, and the stupefied outstanding metope of post have impact on the performance of building function and the discomfort of visual perception.Special-shaped column structure has the feature with infilled wall uniform thickness, therefore avoids the stupefied outstanding metope of post, increases the actual usable floor area in room, improves " percentage of usable dwelling area ", the dark favor being subject to owner and user.Along with the commercial building such as house, office is constantly towards high-rise and high-rise future development, the width of special-shaped column structure post limb certainly will will strengthen, and creates and builds the contradiction between using function therefrom, limit promoting the use of of special-shaped column structure.China is vast in territory, is mostly in earthquake zone, and the invasion and attack of violent earthquake very likely occur.Compared with traditional steel concrete (RC) rectangular column, the shock resistance of shaped rc columns is weakened because of cross section special-shaped, and the anti-seismic performance therefore how improving special-shaped column structure is also a great problem.
In order to meet the demand of structural-load-carrying capacity and anti-seismic performance, the attention that steel performance is more and more subject in industry because it takes into account above-mentioned two kinds of factors.Steel reinforced concrete (SRC) combining structure is as a class form of steel performance, and not only have the Common advantages of combining structure, namely supporting capacity is high, anti-seismic performance good; And compare steel work, encased structures, the concrete of outsourcing makes the endurance quality of inner steel and fire resistance all be improved.Research shows: steel reinforced concrete special-shaped columns, because being configured with more steel in its cross section, makes steel ratio greatly increase, thus is all strengthened than RC hetermorphiscal column in weight capacity and antidetonation index.
In Practical Project, there is the skew (such as balcony corner) of part frame structural grid axis, cause column section form to change, the form greatly mainly with Z-section exists.Due to the particularity of its position, the possibility that this kind of Z-shaped hetermorphiscal column is subject to moment of torsion is very big, and therefore its stressed post than being positioned at all the other positions of frame construction is more complicated.For Z-shaped steel reinforced concrete special-shaped columns, steel is joined mainly with form configurations such as steel flanged beam steel, T steel, channel-section steels in its cross section, and after the concrete cover of removing shaped steel, along on limb cross direction, they exist with the form of real abdomen at each post outlimb.But, consider that the factor such as steel rate, infilled wall thickness is joined in cross section, the shaped steel protective layer thickness of steel reinforced concrete special-shaped columns has certain limit, what have even can only meet minimal protective cover thickness, so causes the space between the outward flange of post to shaped steel external surface relatively narrow and small, when carrying out construction casting, very easily produce coarse aggregate in concrete to be difficult to decline because aggregate size is slightly large, to vibrate difficulty, produce cover concrete thus and build leakiness, affect the endurance quality of structural column itself; And be positioned at the staggered position of beam column node area, in beam, Reinforcement is because of the stop of abdomen form steel real in post, and be difficult to penetrate joint cores, this very likely causes the power transmission of node to be lost efficacy because of beam anchorage improper measures, and consequence is very serious.
Wear the inconvenience on steel (muscle) based on the difficulty of existing shaped-steel layout in construction and beam column node area, active demand one both can meet joins the requirement of steel rate, is conducive to again constructing and the shaped-steel layout of joint anchorage applies in Z-shaped steel reinforced concrete special-shaped columns.

Z-shaped concrete profiled pile is Framed Structure with Special-Shaped Columns center pillar net is not collinear structural column.。
Shaped steel sews by steel the Z-shaped lattice dimensional angle iron framework that part is interconnected to form four sides hollow out by vertical angle steel, and vertical angle steel is separately positioned on Steel Space skeleton (Z-shaped concrete profiled column section) each corner.
In the Z-shaped steel reinforced concrete special-shaped columns of above-mentioned supporting role's steel frame, angle steel is sewed part by steel and to be interconnected according to a determining deviation (be called and sew distance) and to form, generally connected by the mode of welding, angle steel is realized by two kinds of modes and being interconnected between part sewed by steel in practical structures, horizontal cross can be adopted to connect, horizontal cross also can be taked to hold concurrently intersect oblique form to connect.Specific as follows:
Steel is sewed part and is all welded on angle steel with the form of horizontal cross, and vertically each steel is sewed between part and arranged a determining deviation, and this kind of connected mode construction is simple and clear.
Steel sew part with horizontal cross hold concurrently intersect oblique form be welded on angle steel, vertically each steel is sewed between part and is arranged a determining deviation, in spacing (sewing distance), part sewed by oblique welding one steel, and up and down oblique steel is sewed part and is joined end to end, left and right oblique steel sews part head head or tail tail is connected, and this kind of connected mode is beneficial to the raising of Z-shaped hetermorphiscal column shear-carrying capacity.
For the deficiency that existing Z-shaped concrete profiled pile exists, inventor has devised the Z-shaped steel reinforced concrete special-shaped columns of supporting role's steel frame of the present invention, it is by being configured in Z-section concrete profiled pile by the dimensional angle iron framework of four sides lattice, enhance the mutual bonding between Steel concrete, achieve both real combinations; Keep rational steel to sew part spacing, when overcoming concreting, aggregate is difficult to fill up the problem in narrow and small shaped steel topping region, facilitates construction progress; Z-shaped dimensional angle iron framework formula cover cage can retrain the lateral deformation of its inner concrete, improves the bearing capacity of post itself, also helps reinforcing bar or shaped steel in frame joint district beam and penetrates hetermorphiscal column post limb inside, strengthen the anchoring effect of node.
