Abstract

The utility model relates to a steel reinforcement cage, and in particular relates to a tubular pile steel reinforcement cage mixed with a non-prestressed reinforcing steel bar. The tubular pile steel reinforcement cage structurally comprises prestressed reinforcing steel bars surrounded by a hooping; the both ends of the reinforcing steel bar are embedded in end head board iron sheets in a clamping manner; and the non-prestressed reinforcing steel bar is welded at one head of the end head board iron sheets at the both ends of the prestressed reinforcing steel bars. Compared with the prior art, the tubular pile steel reinforcement cage has the characteristics of reasonable design, simple structure, low manufacturing cost, strong anti-tension stress, optimal ductility and the like.

Description

A kind of pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement
Technical field
The utility model relates to a kind of reinforcing cage, and a kind of pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement specifically is provided.
Background technology
In the prestressed high strength concrete pile tube under the prior art, its reinforcing cage adopts prestressed reinforcement more, prestressed reinforcement in the pile tube tensile stress that reaches capacity, because the elongation at break of prestressed reinforcement is less, brittle fracture can occur in pile tube, topples similarly in the event with No. 7 building integral body in scape garden, lotus flower riverside, Shanghai in 2009, and presstressed reinforcing steel is broken, the tension stress of this class pile tube is little, can not satisfy instructions for use.
Summary of the invention
The utility model is for above problem, and a kind of pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement is provided, and it can improve tensile stress and the rate that stretches of the reinforcing cage of existing prestressed high strength concrete pile tube.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement comprises the prestressed reinforcement that surrounds by stirrup, and described presstressed reinforcing steel two ends inlay card is provided with nonprestressed reinforcement between the end plate iron plate at prestressed reinforcement two ends in the end plate iron plate.
Be provided with prestressed reinforcement entrance hole and prestressed reinforcement fixing hole on the end plate iron plate, the end gland of described prestressed reinforcement is fixed in the described prestressed reinforcement fixing hole.
Be to be furnished with nonprestressed reinforcement on the reinforcing cage body between the end plate iron plate at prestressed reinforcement two ends, or nonprestressed reinforcement be welded on the end plate iron plate of a side.
Be provided with prestressed reinforcement entrance hole and prestressed reinforcement fixing hole on the end plate iron plate, the end gland of described prestressed reinforcement is fixed in the described prestressed reinforcement fixing hole.
A kind of pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement of the present utility model, configuration nonprestressed reinforcement (plain bars) afterwards, and is simultaneously stressed with prestressed reinforcement, when bearing seismic loading, because the good plasticity of plain bars is so that the energy dissipation capacity of pile tube improves.
A kind of pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement of the present utility model, the stirrup side pricks or is welded on the prestressed reinforcement, diameter in the scope of the diameter of non-prestressing tendon stirrup from 8mm to 28mm is selected, described prestressed reinforcement two ends are provided with the presstressed reinforcing steel gland, described presstressed reinforcing steel gland is fixed on the presstressed reinforcing steel fixing hole by the presstressed reinforcing steel entrance hole on the end plate iron plate that (the presstressed reinforcing steel gland is by presstressed reinforcing steel fixing hole chucking end plate iron plate, the end can or directly be welded tight by the fixing chucking of nut), nonprestressed reinforcement directly is welded on the end plate iron plate, or forms a circle with the parallel and former body reinforcing cage of reinforcing cage master muscle (vertical muscle).Help to prick or the nonprestressed reinforcement length of welding from 1 meter to not waiting with pile tube is long, and the length of the non-prestressing tendon of other end is unrestricted, adopts a form that is welded on the end plate.
A kind of pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement of the present utility model has strengthened ductility and the shearing resistance of pile tube, and general pile tube is used is that the high-strength steel bar of fragility runs into earthquake meeting meeting and easily cuts off.
Compared with prior art, a kind of pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement of the present utility model, its radical of joining non-prestressing tendon is selected from 3 to 28 number of ranges, the pile tube model from Scope in the reinforcing cage of the non-prestressing tendon of joining.It has characteristics reasonable in design, simple in structure, that cost of manufacture is low, tension stress is strong.
Description of drawings
Fig. 1 is a kind of structural representation that is mixed with the pipe pile reinforcing bar cage of nonprestressed reinforcement;
Fig. 2 is a kind of structural representation of end plate iron plate of the pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement.
The specific embodiment
Below in conjunction with the drawings and specific embodiments a kind of pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement of the present utility model is further described.
As shown in Figure 1, a kind of pipe pile reinforcing bar cage that is mixed with nonprestressed reinforcement, comprise the prestressed reinforcement 2 that surrounds by stirrup 1, described prestressed reinforcement 2 two ends inlay cards are welded with nonprestressed reinforcement 4 between the end plate iron plate 3 at prestressed reinforcement 2 two ends in end plate iron plate 3.
As shown in Figure 2, be provided with prestressed reinforcement entrance hole 5 and prestressed reinforcement fixing hole 6 on the end plate iron plate 3, the end gland of described prestressed reinforcement 2 is fixed in the described prestressed reinforcement fixing hole 6.
Be provided with nonprestressed reinforcement 4 on the end plate iron plate 3, with the same circumference of former reinforcing cage, be evenly distributed on the weld 7 on the end plate iron plate, described nonprestressed reinforcement weld 7 is used for interspersed nonprestressed reinforcement 4 and welding, and the length of other end non-prestressing tendon is not limit, and should not be welded on the end plate of other end.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
