A construction method of an exposed steel column base comprises the following steps: s1: reserving a cup opening at the installation position of the section steel column, and S2: embedding foundation bolts, S3: carrying out layered pouring maintenance on the concrete of the foundation slab, and S4: hoisting the section steel column and adjusting the verticality and elevation, S5: and pouring concrete at the cup mouth. According to the construction method, the cup mouth is formed in the bottom space of the steel column foot, the reserved space is large, the elevation and verticality adjustment of the section steel column is convenient to operate, and the construction efficiency is high; concrete can be directly poured, pressure equipment is not needed, and the construction cost is low; in addition, common concrete pouring can be adopted to replace pressure grouting, high-grade concrete can be poured into the cup mouth according to construction requirements, construction operation is easier to control, and quality is easy to guarantee; because the annular steel plate and the foundation bolt are welded and fixed during construction, and the annular steel plate is laid on the reinforcing steel bar net of the bottom plate, the elevation control is facilitated, the local compressive strength is enhanced, and the column base pressure is uniformly dispersed.
Description
Technical field
The present invention relates to a kind of construction techniques, a kind of exposed steel kind design construction method.
Background technology
In construction steel structure, the effect of steel kind design is that the axle power of steel column bottom, shearing, moment of flexure are passed to basis, makes
Superstructure is effectively connected together with basis；Steel kind design is generally divided into exposed steel kind design, insert-type steel by structural form
Suspension column and outer-enwraped type steel kind design, exposed steel kind design refer to base plate at the bottom of post or boots beam be fixed on by crab-bolt on the basis of suspension column
Form, the most conventional exposed steel kind design construction method is to use foundation bolt construction, owing to the i.e. steel column of reinforced concrete column is installed
Need to carry out reinforced concrete column absolute altitude after in place and perpendicularity adjusts, so one can be reserved bottom reinforced concrete column and between sole plate
The small space of about 5cm, reinforced concrete column absolute altitude and perpendicularity take measure that secondary pressure is in the milk, more i.e. with thin after having adjusted
Stone concrete pressure grouting, grouting quality reaches the closely knit entirety that can form uniform stressed.
This construction method is disadvantageous in that:
1. reinforced concrete column perpendicularity adjustment enforcement space is less, inconvenient operation；
2. two construction qualities are difficult to ensure that, easily form hollowing, and steel kind design power transmission is uneven；
3. need to use press device and team's group of pressure grouting, cause cost to increase.
Summary of the invention
The back-grouting difficult quality that the purpose of the present invention generally exists in constructing for exposed steel kind design controls, reinforcing bar
Post perpendicularity adjusts the problem of difficulty, improves existing construction technology, thus reaches steel column and be connected more with sole plate
Reliably, perpendicularity adjusts the easiest purpose, improves construction quality.
The present invention adopts the technical scheme that: a kind of exposed steel kind design construction method, comprises the steps:
S1: stay in steel column installation position and set rim of a cup
Lay sole plate reinforcing bar, and press periphery, the steel column position inserting column joint bar of drawing setting, at sole plate reinforcing bar and
After post joint bar has been constructed, within one week, carry out blocking along post joint bar with steel wire or fast-easy closing-up net and set formation rim of a cup, the degree of depth of blocking
The i.e. rim of a cup degree of depth adapts with the lift height of sole plate concreting, for 50-100cm；The shape of rim of a cup and steel column
Unanimously, or it is square column, or is cylinder；
S2: pre-embedded anchoring bolts
S21: the doughnut-shaped steel plate corresponding with steel column sole is set, foundation bolt is weldingly fixed on doughnut-shaped steel plate；
S22: doughnut-shaped steel plate is erected on the reinforced mesh of sole plate, and use spot welding to fix in surrounding, it is positioned at annular steel
The foundation bolt of plate bottom puts in sole plate；
S23: be positioned at the foundation bolt upper ends adjusting nut on doughnut-shaped steel plate top；
S3: sole plate concrete is carried out placement layer by layer, maintenance
S31: placement layer by layer sole plate, first pours rim of a cup underlying layers, pours rim of a cup before rim of a cup underlying layers concrete initial set
Concrete outside block, rim of a cup molding；
S32: timely cover film carries out concrete curing after concreting completes；
S4: lifting steel column also adjusts perpendicularity and absolute altitude
Make its sole be inserted in foundation bolt steel column lifting, nut is installed and fixes temporarily, and draw in surrounding and set guy
It is fixing that rope carries out auxiliary to steel column, then utilizes adjusting nut to carry out the adjustment of perpendicularity and absolute altitude；
S5: pour rim of a cup concrete
Pouring rim of a cup with the pea gravel concreten of a high label, steel kind design has been constructed.
Its further technical scheme is: before carrying out step S5, first that the garbage-cleaning in rim of a cup is clean, as arranged
Use steel wire to block during rim of a cup to set, then need concrete interface is carried out dabbing process, then brush one plain concrete viscous to strengthen
Knot power.
Owing to taking above technical scheme, a kind of exposed steel kind design construction method of the present invention has following useful effect
Really:
1. steel kind design bottom space is carried out " amplification " by block device and is reduced to below sole plate by this construction method, shape
Becoming a rim of a cup, cup mouth size is bigger than conventional headspace, and steel column absolute altitude and perpendicularity adjust easy to operate, efficiency of construction
High；
2. more much bigger than conventional headspace due to steel column bottom space (rim of a cup) size, it is possible to directly to pour coagulation
Soil, material requested equipment is simple, it is not necessary to use press device, it is not necessary to using team's group of pressure grouting, construction cost is low；
The most in addition common concreting can be used to replace pressure grouting, and constructing operation is easier to control, and quality is easily guaranteed that；
4. using doughnut-shaped steel plate to be welded and fixed with foundation bolt time due to construction, doughnut-shaped steel plate can be laid on the bar-mat reinforcement of base plate
On, not only contribute to the fixing of foundation bolt, and beneficially elevation control, the beneficially comprcssive strength of reinforcement local are the most all
Even dispersion column foot press power；
5. can need in rim of a cup, irrigate high-grade concrete according to construction, be more beneficial for suspension column stress.
Below, in conjunction with accompanying drawing, the technical characteristic of a kind of exposed steel kind design construction method of present invention invention is made further
Explanation.
