Description
Technical field:
The utility model relates to the pre-buried structure of a kind of contrary working method engineering rigid steel pile segmentation, specifically in being connected of reverse construction middle and lower part concrete stiffness post and steel superstructure, switching node structure.
Background technology:
At present at home in the soft foundation construction work reverse construction, the permanent structure load-bearing pillar adopts pre-buried steel lattice column or steel pipe in reinforced concrete bored pile substantially, steel lattice column or steel pipe directly anchored in the concrete structure of top after substructure was finished, solve the structure vertical applied force by steel lattice column or steel pipe, finish the conversion of bottom concrete stiffness post and top concrete structure.Therefore just solved switch technology in the reverse construction to bottom concrete stiffness post, top concrete structure in the past.And to the conversion of bottom concrete stiffness post and steel superstructure beyond example still.
Summary of the invention:
The pre-buried structure of rigid steel pile segmentation that technical problem to be solved in the utility model is to provide a kind of easy construction, saves cost, to finish the conversion of bottom concrete stiffness structural column and steel superstructure:
The technical scheme of the utility model technical solution problem is as follows:
The pre-buried structure of a kind of contrary working method engineering rigid steel pile segmentation is characterized in that, comprises rigid steel pile, pre-embedded steel slab, embedded steel tube and crab-bolt;
Described rigid steel pile lower end is provided with the stiffness column base plate, and base plate is provided with anchor hole and grout hole;
Pre-embedded steel slab is embedded in the structural concrete layer, and the upper surface of steel plate exposes outside the structural concrete layer, and steel plate is provided with through hole;
Embedded steel tube is embedded in the structural concrete layer, and the steel pipe mouth aligns with through hole on the pre-buried base plate;
Fixedly connected by nut with the stiffness column base plate in described crab-bolt upper end, the through hole that the crab-bolt lower end is passed on the pre-buried base plate extend in the embedded steel tube; The aperture of through hole is greater than the diameter of crab-bolt on pipe diameter and the pre-buried base plate.
During use respectively the periphery setting at stiffness column base plate and pre-buried base plate block the grouting template all around, the gap grouting of grout hole by the stiffness column base plate between gap, embedded steel tube and crab-bolt between stiffness column base plate and the pre-buried base plate, thus make pre-buried structure of the utility model rigid steel pile segmentation and the substructure layer of concrete structure that reliably is connected in one.
By above disclosed technical scheme as can be known, the beneficial effects of the utility model are as follows:
1, can make permanent Construction of Steel Structure, connection, installation in the building structure be adapted to " method of a post ", the common practice of " many methods of a post " that present contrary sequence method adopts; Satisfy construction basement ± 0.00 plate earlier simultaneously, make ± 0.00 plate can allow to continue to dig the operating mode that dark contrary sequence method is generally followed downwards after forming the first road planar support effect of foundation ditch again.
2, the segmental installation of steel column, contrary connect the effect of forming a connecting link with playing, can in certain allowed band, adjust the structural orientation size flexibly.Be corrected in the construction deviation that the column pile sinking stage produces.Avoided the irreversible error of a pile sinking generation.Make it in correction, to reach the high accuracy standard of steel superstructure professional construction.Adopt node processing to solve concrete structure column and steel structure column off normal problem, saved the expense that needs piling because of interim column off normal.
3, do not need steel lattice column or whole of steel pipe are inserted in the bored pile, saved most permanent steel lattice column or steel pipe, structure node gentlier can be selected less lifting appliance for use in addition, reduces expense for using mechanical equipment greatly and uses.
4, the two ends straight screw sleeve was connected and fixed about structure reinforcing bars adopted embedding inlay technique around the rigid steel pile.Solved from two possibilities that direction is fixedly connected the inconvenience of having avoided the electric welding operation to bring simultaneously again.
5, steel column footing steel plate is connected with the structural concrete member to adopt and presets stone bolt earlier, and the method for the high-strength structure grouting of after-pouring material makes it reliably to link the formation fixed end with concrete structure.
