Abstract
The invention discloses a reinforcing structure of a rigid crossbeam of a steel column base bottom plate which includes a steel column (1), a side stiffening rib plate (2), a middle stiffening rib plate (3), a column base bottom plate (4) and a column base bolt (7). A rigid crossbeam (6) is welded with a column base flange slab; anchor reinforcing steel bars (8) are welded at the bottom part of the rigid crossbeam (6); concrete (5) is cast in the intercolumnar range; the concrete (5) is 100mm higher than the top part of the rigid crossbeam (6); the space between the anchor reinforcing steel bars (8) is 150mm; the diameters of the anchor reinforcing steel bars (8) are 16mm to 20mm. The grade of the concrete (5) is not lower than C20. The invention aims at the defects that the traditional reinforcing measure has construction difficulties, long welding lines and is easy to generate a larger welding deformation when solving the insufficient thickness of the column base bottom plate, realizes the reinforcement for the column base bottom plate, is simple and easy to be implemented and has strong operability.
Description
Technical field
The present invention relates to a kind of bottom plate of steel column foot ruggedized construction, can realize the reinforcing of coupled columns sole.
Background technology
Steel building is because its quick construction, build is light and handy, be applied in the building structure in recent years increasingly extensively, particularly be applied in the factory building structure more, and as the member of the final power transmission of steel structure system, the safety of steel column foot just more seems particularly important, sometimes because design, artificial deviation appears in the construction, or the construction finish after building increased extra load again, and when finding these problems, steel column foot has often been constructed and has been finished, this moment is because suspension column base plate thickness deficiency, its insufficient rigidity is with the bending moment of opposing on the base plate, the base plate distortion that just can be distorted this moment, even destroy, threaten the safety of total, at this moment just must carry out consolidation process suspension column.For the not enough reinforcement measure of suspension column base plate thickness, usually all be on original base plate, to set up the suspension column floor of putting more energy into, reduce the span of base plate with this, thereby reduce the suffered bending moment of base plate, but this method is often because the size of suspension column own is less, or the existing floor of putting more energy into is very close and cause in the construction welding very difficult, brings great difficulty for the construction reinforcement, is not easy to implement.
Fig. 1, Figure 2 shows that the suspension column full-page proof of traditional steel work, steel column 1 is made up of two i shaped steels, and side put more energy into floor 2 and intermediate stiffener plate 3 are arranged on suspension column base plate 4, and suspension column base plate 4 and the side floor 2 of putting more energy into also is connected by suspension column bolt 7.When running into the base plate thickness deficiency and need reinforcement,, promptly increase the base plate number of ribs of putting more energy into if adopt traditional reinforcement means.As can be seen from the figure, because floor is overstocked, during construction, the floor that welds these increases can be very difficult, and in addition owing to the length that increases weld seam is very long, also easy the generation than big welding stress causes bottom deformation.
Summary of the invention
The technical problem to be solved in the present invention is: have constructional difficulties and the long weak point of welding deformation greatly that easily produces of weld seam at traditional reinforcement measure when solution suspension column base plate thickness is not enough, propose a kind of new rigid beam reinforced structure for bottom plate of steel column foot, can more simply and effectively be reinforced bottom plate of steel column foot.
The present invention constitutes like this: it comprises steel column, side put more energy into floor, intermediate stiffener plate, suspension column base plate, suspension column bolt, rigid beam and suspension column frange plate are for being welded to connect, weld anchor draws reinforcing bar, concreting in the intercolumniation scope in the rigid beam bottom.
Concrete height should exceed rigid beam top 100mm.
It is 150mm that anchor draws bar space, and diameter is 16mm～20mm, and should adopt the II grade reinforcing steel that has decorative pattern.
Concrete grade is higher than C20.
By above structure, anchor draws reinforcing bar to stretch into the interior adhesion stress with increase and concrete and suspension column of concrete, thereby increase base plate rigidity, make concrete and suspension column base plate form one, common opposing suspension column bending moment, thereby can play good consolidation effect, the difficulty that has been occurred in the construction when having avoided adopting traditional reinforcing mode has also reduced the bottom deformation that welding stress that traditional reinforcing mode causes to base plate causes; And structure of the present invention is more simple and easy to do, and operability is very strong.

Fig. 3 is structural representation of the present invention, vertical view;
Fig. 4 is the sectional view of Fig. 3 along its B-B line.
The specific embodiment
Embodiments of the invention: as shown in Figure 3, Figure 4, can carry out as follows when adopting reinforced column sole of the present invention:
The first, the paint and the iron rust of steel surface in the suspension column scope are thoroughly removed totally, can add the adhesion stress of reinforced concrete and suspension column like this;
Second, between two i shaped steels of steel column 1, set up rigid beam 6, for guaranteeing that this crossbeam has enough rigidity, unlikelyly under load action, deform, its cross section should be enough big, general crossbeam height is taken as 0.4L, L is the spacing of steel column two i shaped steels, and this rigid beam and suspension column frange plate adopt three weld all arounds, and the length of rigid beam is L-20mm, leave certain slit like this between crossbeam and the post, be convenient to insert and construct.The bottom of above-mentioned rigid beam should weld anchor in advance and draw reinforcing bar 8, the spacing of dowel is 150mm, diameter is between 16～20mm, for increasing adhesion stress, dowel should adopt figuratum II grade reinforcing steel, and the length of dowel is 20d, d is the dowel diameter, when if this length fails to lay down greater than the suspension column width, can be bent growing part, make the dowel that an end has crotch;
The 3rd, build pea gravel concreten 5 in the suspension column spatial dimension, concrete grade should be higher than C20, and the height of young concrete should exceed rigid beam top 100mm, the concrete of this 100mm both can be used as the protective layer thickness of crossbeam, can further strengthen the adhesion stress with post again;
The 4th, increase the compactness of young concrete by vibrating repeatedly, bond closely to guarantee rigid beam and dowel that the bottom is with thereof and concrete, with the base plate co-operation.
