Background technology
In the high-rise steel structure building construction process, what the connectivity problem of steel column and reinforcing bar was more and more outstanding shows in face of design and the unit in charge of construction.How effectively, be connected easily steel member and reinforcing bar be the key point that realizes steel work and steel and concrete structure combination.At present, insert in the work progress of base plate at steel column, the base plate reinforcing bar is reserved the way of posthole and welded reinforcement junction plate with generally taking conventional base plate being connected of steel work, is subjected to the influence of on-the-spot member installation accuracy and material difference, and there are the following problems:
A, field Welding reinforcing bar and steel member, weldquality are difficult for guaranteeing that the welding position is difficult to realize;
B, field Welding engineering quantity are big, are unfavorable for construction speed;
C, reservation posthole need second pouring;
D, transverse horizontal reinforcing bar and vertical reinforcement are collided, and can't avoid;
E, can't realize in the posthole scope between two sleeves to twisting, and this section reinforcing bar in the posthole scope is difficult for the straight line butt joint.
Summary of the invention
The present invention is intended to solve existing base plate reinforcing bar and is connected the problems referred to above that exist with steel column, and provides a kind of base plate that strengthens to be connected with steel column, simplifies the high-rise steel structure steel column foot of construction technology and the method for attachment of base plate reinforcing bar.
The technical scheme that the present invention solves described problem employing is: the method for attachment of a kind of high-rise steel structure steel column foot and base plate reinforcing bar, the steps include: that A. finishes the ring flat-plate of putting more energy into that following steps: a. arranges in steel column foot periphery weld horizontal in factory, according to steel column type shape, the described ring flat-plate of putting more energy into is integral with the upper ring plate Combination Welding by four or four, outer rim is rectangular, and the plate face is provided with wears the muscle hole; B. at the ring flat-plate four limit ora terminalis welded reinforcement connectors of putting more energy into, described reinforcing bar connector is the sleeve with internal thread, the one group of corresponding sides of putting more energy in ring flat-plate four limits are wherein slotted respectively, by inserting reinforcing bar welded reinforcement connector in the groove, other one group of corresponding sides are respectively by the welding riser vertical with the ring flat-plate of putting more energy into welded reinforcement connector again, and the reinforcing bar connector on two groups of corresponding sides is upper and lower staggered; B. the steel column that has welded put more energy into ring flat-plate and reinforcing bar connector in the factory is transported to the job site, finish the installation of steel column after, base plate top layer steel bar end processed behind the external screw thread to screw with reinforcing bar connector be connected, promptly finish being connected of steel column foot and base plate reinforcing bar.
The present invention compares with conventional method, and concrete advantage is as follows:
1. solved the problem that on-the-spot reinforcing bar and steel column can't be connected in design and process segment;
2. field Welding reinforcing bar difficulty is big, and quality can't guarantee, is optimized to factory's welding, saves time, material, manpower;
3. avoided the reservation posthole, need not secondary pouring, once-cast is finished, and effect improves, and the holistic resistant behavior of base plate and steel column improves;
4. ring flat-plate plays the resistance to plucking effect, and what the post vertical reinforcement passed ring flat-plate wears the muscle hole, plays the effect of stirrup, has strengthened the globality of external wrapping concrete and steel column.
Description of drawings
Put more energy into for the H steel column the adds structural representation of ring flat-plate and reinforcing bar connector of Fig. 1.
Put more energy into for the fish bone well steel column the adds structural representation of ring flat-plate and reinforcing bar connector of Fig. 2.
Among the figure: H steel column 1, ring flat-plate 2, riser 3, reinforcing bar connector 4 is strengthened gusset 5, wears muscle hole 6, reinforcing bar and reinforcing bar connector 7, fish bone well steel column 8.
The specific embodiment
Below in conjunction with drawings and Examples in detail the present invention is described in detail.
Referring to Fig. 1, steel column is a H steel column 1 among the figure, by the method for put more energy in the suspension column increase of this H steel column 1 ring flat-plate and welded reinforcement connector, makes that reinforcement foundation is effective with steel column foot, easy, rational to be connected, and concrete steps are as follows:
1. in factory, do qualification of welding procedure: according to the material of ring flat-plate 2 and reinforcing bar connector 4, carry out corresponding qualification of welding procedure, to guarantee that ring flat-plate 2 is connected with the reliable of H steel column 1 with reinforcing bar connector 4.
2. in factory, weld put more energy into ring flat-plate and reinforcing bar connector 4, and carry out the protection of reinforcing bar connector 4 inner thread heads: the ring flat-plate of arranging in H steel column 1 suspension column periphery weld horizontal of putting more energy at first, this ring flat-plate of putting more energy into is integral by four ring flat-plate 2 Combination Welding, outer rim is rectangular, and the plate face is provided with wears muscle hole 6; Then at the ring flat-plate four limit ora terminalis welded reinforcement connectors 4 of putting more energy into, this reinforcing bar connector 4 is for having the sleeve of internal thread, the one group of corresponding sides (upper and lower limit among Fig. 1) of putting more energy in ring flat-plate four limits are wherein slotted respectively, connect reinforcing bar and reinforcing bar connector 7 by the mode of inserting the reinforcing bar weldering in the groove, the reinforcing bar connector 4 on 4, two groups of corresponding sides of welded reinforcement connector is upper and lower staggered again by the welding riser 3 vertical with ring flat-plate 2 respectively for other one group of corresponding sides (left and right limit among Fig. 1).For improving the bonding strength between riser 3 and the ring flat-plate 2, between also is welded with the reinforcement gusset 5 of triangular structure.
3. the steel column that has welded put more energy into ring flat-plate and reinforcing bar connector in the factory is transported to the job site, base plate top layer reinforcing bar has been laid at the scene, Steel Structure Installation personnel need pierce the installation of carrying out steel column in the base plate reinforcing bar, after finishing the installation of steel column, base plate top layer steel bar end processed behind the external screw thread to screw with reinforcing bar connector 4 be connected, promptly finish being connected of steel column foot and base plate reinforcing bar.
