Abstract
The utility model relates to a reinforced type bamboo joint pile. The reinforced type bamboo joint pile mainly comprises a bamboo-joint-shaped concrete hollow pile body and a steel bar cage arranged in the bamboo-joint-shaped concrete hollow pile body. The reinforced type bamboo joint pile is characterized in that the steel bar cage adopts a structure combining prestressed steel bars and non-prestressed steel bars. The non-prestressed steel bars are added on the steel bar cage on the basis of the traditional prestressed steel bars, so that bending resistance and shearing resistance of the bamboo joint pile are improved, and reinforced type bamboo joint pile is suitable for the occasions with higher anti-seismic levels or supporting and enveloping structures is achieved; and meanwhile, since the non-prestressed steel bars do not need to be tensioned, compared with the prestressed bars, the non-prestressed steel bars are low in cost, so that cost for whole engineering is reduced.
Description
Technical field
The utility model relates to a kind of concrete tubular pile, particularly the reinforced ring stake that a kind of bending resistance shear resistance is strong and cost is low.
Background technology
Along with the development of concrete technology, the technology of concrete tubular pile also reaches its maturity, and except being applied to industry, civilian construction, also is widely used in each field such as bridge, harbour, railway or hydraulic engineering.
The bearing capacity of traditional concrete tubular pile only is subjected to the influence of side skin friction and stake end frictional resistance, if will increase bearing capacity, can only realize by increasing caliber or length, has increased construction cost and difficulty accordingly.The concrete tubular pile that had occurred a kind of surface band reinforcing ring afterwards, i.e. ring stake, it is at pile tube body surfaces setting reinforcing ring spaced apart vertically, utilizes the friction of reinforcing ring and soil to increase the bearing capacity of pile tube.Pure prestressed reinforcement basket structure is all adopted in present ring stake, and in the antidetonation grade in higher or the space enclosing structure, when the bending resistance shear resistance was had relatively high expectations, needing increased prestressed reinforcement accordingly, so cost is higher.
Summary of the invention
The technical problems to be solved in the utility model provides the reinforced ring stake that a kind of bending resistance shear resistance is strong and cost is low.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of reinforced ring stake, mainly comprise laemodipodiform concrete hollow pile body and be built in the interior reinforcing cage of concrete hollow pile body, its innovative point is: described reinforcing cage adopts prestressed reinforcement and nonprestressed reinforcement structure combining.
Further, described reinforcing cage by some along the concrete hollow pile axon to the prestressed reinforcement that extends and distribute ringwise, and be welded on the outer spiral stirrup of prestressed reinforcement and constitute; And reinforcing cage also comprises some nonprestressed reinforcements, described nonprestressed reinforcement along the concrete hollow pile axon to extending and being evenly distributed between the prestressed reinforcement that distributes ringwise.
Further, the welding of described nonprestressed reinforcement and spiral stirrup is fixing.
Advantage of the present utility model is: reinforcing cage increases nonprestressed reinforcement on the basis of traditional prestressed reinforcement, increases the bending resistance shear resistance of ring stake, is applicable to the higher or space enclosing structure occasion of antidetonation grade; Simultaneously, low than the prestressed reinforcement cost because nonprestressed reinforcement need not stretch-draw, therefore reduced the integrated engineering cost.
Description of drawings
Fig. 1 is reinforced ring stake outline drawing in the utility model.
Fig. 2 is along A-A line sectional drawing among Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the ring stake mainly comprises laemodipodiform concrete hollow pile body 1 and is built in reinforcing cage in the concrete hollow pile body, and concrete hollow pile body 1 is intervally distributed with some concrete reinforcing rings vertically by the surface of tubulose pile body main body and constitutes laemodipodiform.
In the reinforced ring stake, reinforcing cage adopts prestressed reinforcement 2 and nonprestressed reinforcement 4 structure combining in the utility model.
Concrete: reinforcing cage is by some prestressed reinforcements 2 that extend axially and distribute ringwise along concrete hollow pile body 1, and the spiral stirrups 3 that are welded on outside the prestressed reinforcement 2 constitute; And reinforcing cage also comprises some nonprestressed reinforcements 4, and nonprestressed reinforcement 4 extends axially and is evenly distributed between the prestressed reinforcement 2 that distributes ringwise along concrete hollow pile body 1.Nonprestressed reinforcement 4 is fixing with spiral stirrup 3 welding.Here the quantity of nonprestressed reinforcement 4 and diameter can be identical or different with prestressed reinforcement 2.
Those skilled in the art are to be understood that: above-mentioned reinforcing cage structure only is exemplary, not circumscribed, as long as adopt prestressed reinforcement 2 and nonprestressed reinforcement 4 structure combining, for example to prestressed reinforcement 2 and nonprestressed reinforcement 4 fixedly the time, can adopt spiral stirrup 3, also can adopt some flange that prestressed reinforcement 2 and nonprestressed reinforcement 4 are fixed.
Claims (3)
1. reinforced ring stake mainly comprises laemodipodiform concrete hollow pile body and is built in the interior reinforcing cage of concrete hollow pile body that it is characterized in that: described reinforcing cage adopts prestressed reinforcement and nonprestressed reinforcement structure combining.
