Abstract
The utility model discloses a shaped steel - concrete makes up stress tube stake in advance, including inner wall, outer wall, reinforced concrete structure, bellows with be used for the steel strand wires of stretch -draw, still including burying the shaped steel in reinforced concrete underground, shaped steel around reinforced concrete structure's axis evenly lay and its extending direction parallel with reinforced concrete structure's axis, shaped steel is laid to concrete structure part by the prestressed concrete pipe pile present, and concrete pipe pile's tensile strength is improved to profiled steel structure's purpose, but also does not change present prestressed concrete pipe pile's performance, effectively combines the high tensile strength of shaped steel and the compressive property of concrete, improves concrete pipe pile's tensile strength, rigidity and the dough stability, but also can effectively avoid appearing concrete structure 1's phenomenon at dark concrete structure 0 in -process, guarantees the normal clear of constructing.
Description
Technical field
The utility model relates to pile for prestressed pipe technical field, particularly relates to a kind of shaped steel-Combined concrete pile for prestressed pipe.
Background technology
Prestressed concrete pipe pile introduces domestic one quick foundation reinforcing structure the end of the sixties in last century, it is fast that it has speed of application, can drive piles continuously and the advantage such as applied widely, prestressed concrete pipe pile can be divided into post-tensioned prestressing stake and pretensioned-prestressed tube pile according to manufacture method.Pretensioned-prestressed tube pile is a kind of hollow cylinder elongate concrete prefabricated units adopting pretensioned prestressing technique and centrifugal casting to make, primarily of compositions such as cylindrical shape pile body, end plate and steel hoops.
But find in Specific construction, traditional prestressed concrete pipe pile tensile strength is low cannot ensure its intensity, rigidity and stability under geological process.And easily there is pile breaking phenomenon in deep foundation pit support field, affect construction speed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of shaped steel-Combined concrete pile for prestressed pipe, fully the tensile strength of shaped steel and concrete compressive strength are combined, improve its intensity, rigidity and stability under geological process, avoid occurring broken pile in deep foundation pit support process
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of shaped steel-Combined concrete pile for prestressed pipe, comprise inwall, outer wall, reinforced concrete structure, bellows and the steel strand for stretch-draw, also comprise the shaped steel be embedded in steel concrete, described shaped steel is evenly laid and the axis being parallel of its bearing of trend and reinforced concrete structure around the axis of reinforced concrete structure.
Described reinforced concrete structure comprises reinforcing cage and perfusion concrete between the inner walls and the outer, and described shaped steel is positioned at inside reinforcing cage.
Described shaped steel is i iron, and the web of described i iron is radially arranged relative to the axis of concrete structure.
Described concrete structure two ends fixedly mount end plate and steel hoop respectively.
The beneficial effect adopting technique scheme to produce is: lay shaped steel by the concrete structure part at existing prestressed concrete pipe pile, the object of formed steel construction improves the tensile strength of concrete tubular pile, and do not change the performance of existing prestressed concrete pipe pile, the high tensile performance of shaped steel and concrete compressive property are effectively combined, improve the tensile strength of concrete tubular pile, rigidity and stability, and effectively can avoid the phenomenon occurring broken pile in deep foundation pit support process, guarantee that construction is normally carried out, for existing simple prestressed concrete pipe pile, when realizing identical object, shaped steel of the present utility model-Combined concrete pile for prestressed pipe is adopted to add large pile spacing, shorten stake long, engineering cost about 5% can be reduced.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In the accompanying drawings: 1, outer wall; 2, reinforced concrete structure; 3, bellows; 4, shaped steel; 5, inwall.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
In order to solve the problem of existing pile for prestressed pipe tensile strength difference and poor stability, the utility model provides a kind of shaped steel-Combined concrete pile for prestressed pipe as shown in Figure 1, comprise inwall 5, outer wall 1, reinforced concrete structure 2, bellows 3 and the steel strand for stretch-draw, also comprise the shaped steel 4 be embedded in steel concrete, described shaped steel 4 is evenly laid and the axis being parallel of its bearing of trend and reinforced concrete structure 2 around the axis of reinforced concrete structure 2; Described reinforced concrete structure 2 comprises reinforcing cage and is poured in the concrete between inwall 5 and outer wall 1, and described shaped steel 4 is positioned at inside reinforcing cage; Described shaped steel 4 is i iron, and the web of described i iron is radially arranged relative to the axis of concrete structure; Described concrete structure two ends fixedly mount end plate and steel hoop respectively.
In embody rule process, reinforced concrete structure in the utility model and inner and outer wall are that integral type pours into a mould structure, inner and outer wall is in fact reinforcement cover, just steel welding is connected on inside reinforcing cage in reinforcing cage manufacture process, shaped steel distance inwall is avoided too closely to affect inwall shaping, shaped steel-Combined concrete the pile for prestressed pipe of casting complete adopts the maintenance process identical with existing pile for prestressed pipe, can use after shaping, using method is identical with existing pile tube, but, the utility model lays shaped steel by the concrete structure part at existing prestressed concrete pipe pile, the object of formed steel construction improves the tensile strength of concrete tubular pile, and do not change the performance of existing prestressed concrete pipe pile, the high tensile performance of shaped steel and concrete compressive property are effectively combined, improve the tensile strength of concrete tubular pile, rigidity and stability, and effectively can avoid the phenomenon occurring broken pile in deep foundation pit support process, guarantee that construction is normally carried out, for existing simple prestressed concrete pipe pile, when realizing identical object, shaped steel of the present utility model-Combined concrete pile for prestressed pipe is adopted to add large pile spacing, shorten stake long, engineering cost about 5% can be reduced.
