Description
Technical field
The utility model relates to building field, particularly the pre-buried a kind of pre-buried structure of stiffness structure reinforcing bar.
Background technology
Along with the fast development of society modernization, emerge in large numbers like the mushrooms after rain the life periphery people take large-scale shopping plaza, museum etc. as superelevation, the ultra-large type building structure of representative.Meanwhile, stiffness structure possesses steel work and concrete structure advantage simultaneously, compared with steel work, and can saving steel, increase the rigidity of member, building, compared with concrete structure, can reduce cross section and weight, increase the ductility of member, there is higher intensity, improved the shock resistance of building, be widely used in already in engineering entity, for building superelevation, super across and the realization of complex model established architecture basics.
Strengthening concrete combining structure is widely used in all kinds of building structure, substantially adopts outer-enwraped type suspension column and two kinds of modes of flush type suspension column for stiffened steel structure suspension column.The utility model technology is mainly puted forth effort the stiffness structure steel column pin construction method that Research foundation raft plate is taken root.
As shown in Figure 1, the former outer-enwraped type suspension column that is designed to of this project, pre-embedded bolt when construction of bottom plates, bolt needs temporary fixed and accurately locates, and allowable variation is 2mm, after underplate concrete has been built, more than suspension column is installed on to crab-bolt, suspension column absolute altitude regulates by post lower nut, allowable variation ± 2mm, the high reserved 50mm of suspension column base plate and structure base slab top mark.Re-use C60 microdilatancy pea gravel concreten space is tamped, finally complete steel column pin and install.
There is defect in construction in this way: 1, need to accurately locate pre-embedded bolt, and reinforce firm, in order to avoid cause bolt off normal while building underplate concrete; 2, treat that underplate concrete intensity meets designing requirement, can carry out suspension column installation, operation latent period is longer; 3, need coupled columns sole back-grouting, narrow space, difficult quality guarantee; 4, grouting meets after designing requirement with concrete strength, can carry out saving under rigid steel pile the lifting work of steel column, waits for longer cycle for the second time.
Summary of the invention
For addressing the above problem, the utility model provides a kind of outer-enwraped type suspension column, pre-embedded bolt accurate positioning, and underplate concrete meets designing requirement, and quality can be guaranteed, and whole work progress waits for that the concrete formation time is short.
For achieving the above object, the utility model provides a kind of outer-enwraped type suspension column, its steel structure column sole is fixedly connected with bolt, steel structure column sole both sides installed height mark adjusting nut and hold-down nut respectively on bolt, it is characterized in that: bolt is fixedly connected with bracing frame, bracing frame is fixed on base plate hypodermis reinforcing bar.
Described steel structure column sole upper surface and floor slab structure absolute altitude are in same level.
Between described base plate hypodermis reinforcing bar and base plate, be fixedly installed concrete pad, between support frame as described above and base plate, be fixedly installed concrete pad.
Between described base plate hypodermis reinforcing bar and bracing frame, be fixedly connected with reinforcing rib.
Described reinforcing rib and base plate hypodermis reinforcing bar single-sided welding 10d, reinforcing rib and bracing frame single-sided welding 10d.
Described reinforcing rib bending angle is 30 °-60 °.
Use the utility model effect remarkable: bracing frame is provided with the through hole that is fixedly connected with bolt, it is more accurate to locate, pre-embedded bolt and the installation of steel work suspension column are carried out simultaneously, reduce the difficulty of construction of secondary lifting suspension column, avoid back-grouting to cause the hidden danger of quality of pre-embedded bolt off normal, the utility model adopts one piece grouting to replace base plate grouting and steel work suspension column grouting back-grouting, reduces difficulty of construction simultaneously, shorten the technology intermission stand-by period of solidifying simultaneously, accelerate the duration.

The specific embodiment
As shown in Figure 2, the utility model provides a kind of outer-enwraped type suspension column, its steel work suspension column 1 base plate is fixedly connected with bolt 2, steel work suspension column 1 base plate both sides installed height mark adjusting nut 7 and hold-down nut 8 respectively on bolt 2, bolt 2 is fixedly connected with bracing frame 3, and bracing frame 3 is fixed on base plate hypodermis reinforcing bar 6.
First make bracing frame 3, bracing frame 3 technical data design height and non-deformability as required, on bracing frame 3, with bolt 2 weld bolt connecting hole positions, junction, the bracing frame 3 completing is welded and fixed and is connected with base plate hypodermis reinforcing bar 6, completes bracing frame 3 is installed.Then welded and installed bolt 2, according to design height installed height mark adjusting nut 7, then lifts steel work suspension column 1 after completing, and steel work suspension column 1 is fixing by clamp nut 8.Can make steel work suspension column 1 plate upper surface and floor slab structure absolute altitude in same level according to designing requirement.Build underplate concrete, while building, built by steel work suspension column 1 one side direction opposite sides, strengthen vibrating, guarantee that steel column foot bottom concrete is closely knit, guarantee the loading characteristic of hinged joint in structural calculation model simultaneously, form packet mode suspension column embedded structure.
Guaranteeing in structure stress situation, we improve former design outer-enwraped type stiffness structure steel column pin form of construction work, more than maintenance suspension column position is positioned at concrete floor, adopt the advantage of a construction molding of flush type suspension column, by steel column foot bottom shrouding Transducers Embedded in Concrete base plate, guarantee tight between suspension column bottom shrouding and concrete, complete a concreting moulding, avoid numerous and diverse operation of back-grouting, also avoid locating the problems such as inaccurate and back-grouting leakiness because cast-in fixing bolt 9 deviations cause steel work suspension column 1 simultaneously, reach the requirement of outer-enwraped type suspension column hinged joint.
The utility model basic structure and preparation method are identical with embodiment 1.
