Abstract
The invention discloses a reinforcing structure of a column base bolt of a steel column which includes a holding down bolt (1), original column base reinforcing steel bars (5) and a column base foundation (8); newly added column base vertical reinforcing steel bars (6) at the most external side and the original column base reinforcing steel bars (5) in the four corners of the column base foundation are connected by adopting a welding mode; the other newly added column base vertical reinforcing steel bars are anchored in the column base foundation (8) by drilling and using epoxy resin mortars; the column base foundation (8) and the original column base reinforcing steel bars (5), the newly added column base vertical reinforcing steel bars (6) at the most external side, newly added column base reinforcing steel bars (9) at the top side and newly added transverse column base reinforcing steel bars (10) are coated by concreting (7). The concreting (7) is 100mm higher than the newly added column base reinforcing steel bars (9) at the top side. The diameters of the newly added reinforcing steel bars are 16 to 20mm and the space between the newly added reinforcing steel bars is 150mm. The grade of the concreting (7) is higher than C20. The reinforcing structure is suitable for carrying out reinforcement when the intensity of the holding down bolt of the steel column is not enough.
Description
Technical field
The present invention relates to a kind of bolt reinforced structure for steel column foot of steel building, use this structure can realize the reinforcement of coupled columns foot bolt simply and effectively.
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 the suspension column bolt strength is not enough, its strength deficiency is with the opposing pressure that post was transmitted, might occur the suspension column bolt in the use and be broken the situation that destruction is taken place, and then threaten the safety of total, at this moment just must give the reinforcement processing by the coupled columns foot bolt.For the not enough reinforcement measure of suspension column bolt strength, usually all be on the reinforced concrete foundation under the suspension column, to hole, bury additionally foot bolt underground with epoxy resin mortar, need set up the rigidity outrigger in addition, could will increase bolt tension force like this newly and pass to the original boots beam of suspension column, thereby play the effect of reinforcement by this rigidity outrigger.Adopt this method to waste time and energy, newly-increased reinforcement bolt and rigidity outrigger need special toward contact, also seem very uneconomical when bringing difficulty to reinforcement work.
Figure 1 shows that traditional reinforced structure schematic diagram, promptly increase the steel work suspension column full-page proof behind the stone bolt.Wherein, (1) is original stone bolt, (2) stone bolt for increasing, and (3) are the boots beam on original suspension column, and (8) are heel foundation, and (4) rigidity outrigger for increasing, this outrigger are to be convenient to the pulling force on the newly-increased bolt is passed to original boots beam.As can be seen from the figure, the stone bolt of increase and rigidity outrigger need special, are unfavorable for gathering materials on the spot the whole reinforcement process not only complexity but also economic inadequately that seems.
Summary of the invention
The technical problem to be solved in the present invention is: at traditional reinforced structure not only complexity but also sub-economic weak point when solution suspension column bolt strength is not enough, propose a kind of new steel column foot reinforced structure, the reinforcement during with realization coupled columns foot bolt strength deficiency.
The present invention constitutes like this: it comprises stone bolt (1), original suspension column reinforcing bar (5), heel foundation (8), newly-increased outermost suspension column vertical reinforcement (6) is connected with original suspension column reinforcing bar (5) employing welding manner in four angles of heel foundation, all the other newly-increased suspension column vertical reinforcements adopt boring and are anchored in the heel foundation (8) with epoxy resin mortar, and concreting (7) is with heel foundation (8) and original suspension column reinforcing bar (5), newly-increased outermost suspension column vertical reinforcement (6), newly-increased top side suspension column reinforcing bar (9), newly-increased horizontal suspension column reinforcing bar (10) parcel.
Concreting (7) is higher than newly-increased top side suspension column reinforcing bar (9) 100mm.
The diameter of described newly-increased reinforcing bar is 16～20mm, and spacing is 150mm.
The grade of concreting (7) is higher than C20.
In above structure, newly-increased reinforcing bar, newly placed concrete form one with suspension column, make anchor into the basis interior newly add reinforcing bar and original stone bolt co-operation, thereby remedied the problem of original stone bolt insufficient strength, easy and finished reinforcement work effectively.
The present invention reinforces when being applicable to steel column stone bolt insufficient strength, some members need special drawback when having avoided adopting traditional reinforcing mode, the reinforcement work that only need use in the engineering reinforcing bar commonly used and concrete just can finish stone bolt, simple, economical, be convenient to operation.
Description of drawings
Fig. 1 is traditional steel column foot reinforced structure schematic diagram;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Embodiments of the invention: as shown in Figure 2, can carry out as follows when adopting coupled columns foot bolt reinforcement of the present invention:
The first, the concrete at four angles of heel foundation 8 is destroyed, expose original suspension column reinforcing bar 5, exposed length should guarantee the weld length requirement, promptly the length of welded lap is 100mm, and with the concrete hacking of basic side;
Second, set up the suspension column reinforcing bar, reinforcing bar adopts the double-layer double-direction configuration, and bar space is 150mm, and diameter d is 16～20mm, for increasing adhesion stress, reinforcing bar should adopt figuratum II grade reinforcing steel, and newly-increased outermost suspension column vertical reinforcement 6 is connected with original suspension column reinforcing bar 5 employing welding manners in four angles of patten, and the length of welded lap is 100mm, the suspension column vertical reinforcement that all the other newly add should adopt boring and be anchored in the original base with epoxy resin mortar, and the degree of depth in hole is 20d;
The 3rd, concreting 7, concrete grade should not be lower than C20, and the height of young concrete is that suspension column stiffener height and position of living in increases 100mm.As can be seen, concreting 7 is wrapped to form one with heel foundation 8 and original suspension column reinforcing bar 5, newly-increased outermost suspension column vertical reinforcement 6, newly-increased top side suspension column reinforcing bar 9, newly-increased horizontal suspension column reinforcing bar 10, make to anchor into and newly add reinforcing bar and original stone bolt co-operation in the basis, thereby remedied the problem of original stone bolt insufficient strength, easy and finished reinforcement work effectively.
