Abstract
The utility model relates to a steel pipe concrete prestressing force single pile basis, including steel pipe and steel reinforcement cage subassembly, do spiredly for one section of the stake, the other end is equipped with the pile cover, the steel reinforcement cage subassembly includes the steel reinforcement cage, and prestressing steel and stirrup, steel reinforcement cage are circular combination formula overall structure, and prestressing steel vertically runs through in the pile body to it is fixed through stirrup and steel reinforcement cage, the prestressing steel both ends are fixed with the pile cover at the bottom of the awl at steel pipe both ends respectively. The utility model discloses a steel pipe and prestressing steel to pour the C40 concrete and form steel pipe concrete prestressing force single pile in the steel pipe, strengthened the intensity of stake and the bearing capacity of pile body, improved the cracking resistance of pile body.
Description
Technical field
The utility model relates to building field, is specifically related to a kind of concrete filled steel tube prestressing force single-pile foundation.
Background technology
Common steel concrete prestressed pile tensile capacity and pile concrete cracking resistance not ideal enough, in special area, as seismic fortification intensity requires higher area, cannot extensive use.And concrete filled steel tube prestressing force single-pile foundation just meets these deficiencies, propose the utility model in this case.
Summary of the invention
The problem that the utility model solves is to provide a kind of concrete filled steel tube prestressing force single-pile foundation, solves the problem of concrete pile tensile capacity and pile body cracking resistance deficiency.
The utility model relates to a kind of concrete filled steel tube prestressing force single-pile foundation, comprises steel pipe and reinforcing cage assembly; One section of stake is done tapered, and the other end is provided with pile cover; Reinforcing cage assembly comprises reinforcing cage, prestressed reinforcement and stirrup, and reinforcing cage is the box-like overall structure of circular group, and prestressed reinforcement longitudinally through pile body, and is fixed by stirrup and reinforcing cage; Prestressed reinforcement two ends respectively at the bottom of the cone at steel pipe two ends and pile cover fix; And in steel pipe, build C40 concrete formation concrete filled steel tube prestressing force single pile.
The utility model simple structure, easy to operate, effectively raise tensile capacity and the cracking resistance of stake.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional drawing of the present utility model;
Reference numeral: 1. steel pipe, 2. tapered steel pipe end, 3. prestressed reinforcement, 4. stirrup, 5. concrete, 6. pile cover.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 1 is structural representation of the present utility model.The utility model relates to a kind of concrete filled steel tube prestressing force single-pile foundation, comprises steel pipe 1 and reinforcing cage assembly; One section of stake is done tapered 2, and the other end is provided with pile cover 6; Reinforcing cage assembly comprises reinforcing cage, prestressed reinforcement 3 and stirrup 4, and reinforcing cage is the box-like overall structure of circular group, and prestressed reinforcement 3 longitudinally through pile body, and is fixed by stirrup 4 and reinforcing cage; Prestressed reinforcement 3 two ends respectively at the bottom of the cone at steel pipe 1 two ends 2 and pile cover 6 fix, and in steel pipe, build C40 concrete 5 form concrete filled steel tube prestressing force single-pile foundation.
Fig. 2 is sectional drawing of the present utility model.The utility model relates to a kind of concrete filled steel tube prestressing force single-pile foundation, and steel pipe 1 adopts diameter to be 0.6m, and wall thickness is the round steel pipe of 6mm; Presstressed reinforcing steel adopts the diameter of HRB400 to be that reinforcing bar strangled by the band of 20mm, adopts pre-tensioning system Shi Hanzhang, and is evenly arranged along steel pipe; Stirrup adopts the diameter of HPB300 to be the plain bar of 8mm, is centered around the distribution of prestressed reinforcement external spiral; Steel pipe inner concrete adopts strength grade to be C40, and one-time-concreting is shaping.
