Abstract
The invention relates to a high-strength pre-stressed steel concrete composite pile, comprising a pile body and two ends plates arranged at both ends of the pile body. The innovation point is that the pile body comprises a concrete hollow pile body, a thin-wall steel pipe and a reinforcement cage, wherein the thin-wall steel pipe is coated at the external part or in whole length of the concrete hollow pile body, and the reinforcement cage is arranged in whole length of the concrete hollow pile body. The pile provided by the invention has the following advantages: because the thin-wall steel pipe is coated at an external part or in whole length of the concrete hollow pile body, and the reinforcement cage is arranged in whole length of the concrete hollow pile body, the advantages of above two materials are brought into full play; the thin-wall steel pipe bears bending moment, thus the pile has the characteristics of bending resistance and excellent anti-shearing property; and the concrete hollow device with the pre-stressed reinforcement cage bears pressure. The thin-wall steel pipe can be allocated in whole-length or partial mode according to anti-horizontal-force demand of actual building, so that the pile is used flexibly. As a reinforcement product of thin-wall steel-pipe centrifugal concrete (TSC) pipe pile, the pile provides more model selection freedom to design and is mainly used for buildings resisting higher anti-horizontal-force property.
Description
Technical field
The present invention relates to a kind of pile tube, particularly a kind of high-strength prestressed steel concrete composite pile.
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.Pile tube comprises prestressed concrete pipe pile (PC pile tube), thin tubular piles produced by prestressed concrete (PTC pile tube), prestressed high-strength concrete pile (PHC pile tube), centrifugal tubular pile with concrete of thin-wall steel pipe (TSC pile tube).
The TSC stake, its profile is similar to PHC stake commonly used, but inherent structure is different.The shell of TSC stake is the thin-wall steel tube of several millimeters thick, built-in reinforcing cage, and dowel is welded on the end plate.(this Novel tubular pile of Z@-e^R has the characteristics such as bending resistance is effective, pile quality is excellent, the cost of material is low, and it is imperative therefore to research and develop a kind of compound concrete pile tube.
Summary of the invention
The technical problem to be solved in the present invention provides the high-strength prestressed steel concrete composite pile that a kind of horizontal force resistant is good, bearing capacity of single pile is high.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of high-strength prestressed steel concrete composite pile, the end plate that comprises pile body and pile body two ends, its innovative point is: described pile body comprises concrete hollow pile body, thin-wall steel tube and reinforcing cage, the external coating thin-wall steel tube of concrete hollow pile; Configuration prestressed reinforcement cage in the concrete hollow pile body, prestressed reinforcement cage two ends and end plate are connected and fixed.
Further, at the external elongated configuration thin-wall steel tube of described concrete hollow pile.
Further, at the external local configuration thin-wall steel tube of described concrete hollow pile.
Further, described reinforcing cage, and is welded on the outer spiral stirrup of prestressed reinforcement and consists of along the concrete hollow pile axon to the prestressed reinforcement that extends and distribute ringwise by some, and prestressed reinforcement two ends and the end plate of reinforcing cage are connected and fixed.
The invention has the advantages that: part or elongated configuration thin-wall steel tube outside the high strength concrete hollow pile body, the elongated preparation reinforcing cage of configuration in the pile body, give full play to the advantage of this bi-material; thin-wall steel tube bears moment of flexure; have bending resistance, the excellent characteristics of shear behavior, bear pressure with the concrete hollow device of prestressed reinforcement cage.Thin-wall steel tube adopts elongated or local configuration can require to determine according to the Practical Project horizontal force resistant, uses flexibly.It for design provides more type selecting space, is mainly used in the larger building of horizontal force resistant as a kind of enhancement mode product of TSC pile tube.

The specific embodiment
As shown in Figure 1, 2, comprise concrete hollow pile body 1, thin-wall steel tube 2, end plate 3, prestressed reinforcement 4, spiral stirrup 5.
The end plate 3 that above-mentioned high-strength prestressed steel concrete composite pile comprises pile body and is arranged on the pile body two ends, pile body comprises concrete hollow pile body 1, thin-wall steel tube 2 and reinforcing cage, concrete hollow pile body 1 outer elongated coating thin-wall steel tube 2, namely thin-wall steel tube 2 is isometric with concrete hollow pile body 1.
Concrete hollow pile body 1 interior elongated configuration reinforcement cage, reinforcing cage generally by some along the concrete hollow pile axon to the prestressed reinforcement 4 that extends and distribute ringwise, and the spiral stirrups 5 that are welded on outside the prestressed reinforcement 4 consist of, prestressed reinforcement 4 two ends of reinforcing cage are connected with end plate 3, and end plate 3 is welded and fixed with thin-wall steel tube 2.
Fig. 3,4,5 shows the high-strength prestressed steel concrete composite pile of another kind of structure, and its structure and said structure are basic identical, the end plate 3 that includes pile body and be arranged on the pile body two ends, and pile body comprises concrete hollow pile body 1, thin-wall steel tube 2 and reinforcing cage.Difference is: thin-wall steel tube 2 adopts local the coating, and thin-wall steel tube 2 coats and embeds in the concrete hollow pile body 1, guarantees that the external surface of thin-wall steel tube 2 flushes with concrete hollow pile body 1.When thin-wall steel tube 2 adopts local the covering, generally be positioned at the end of concrete hollow pile body 1, an end and end plate 3 are welded and fixed.Quantity also can be two sections or several sections.
