Problems solved by technology

However, square piles and pipe piles also have shortcomings. The disadvantages of square piles are: because the cross-sectional area is not too large, the area around the pile is relatively small, and the frictional resistance of the pile side is also relatively small, so the number of piles per unit project is relatively large; The disadvantages are: the section rigidity is small, the pile body may crack and break during the pile pressing process, and the pile side friction resistance is relatively small

Embodiment Construction

[0015] As shown in Figure 1, the main bars 2 are arranged in a single row, and the main bars 2 and the stirrups 3 are bound by iron wires (not shown in the figure) to form a reinforcement cage. The main bars 2 and the stirrups 3 can be ordinary steel bars or prestressed steel bars . After the concrete 1 is poured, a prefabricated reinforced concrete special-shaped section pile is formed. Concrete 1 can be ordinary concrete or high-strength concrete. Concrete 1 can also add various additives, such as reinforcing agent, early strength agent, water reducer, and anti-crack fiber products, fly ash instead of part of cement. Section 4 is "ten" shape.

[0016] As shown in Fig. 3, the section 4 is in the shape of "I", the main reinforcement 2 and the stirrup 3 are bound by iron wires (not shown in the figure), and the concrete 1 is poured.

[0017] As shown in FIG. 4 , the section 4 is gear-shaped, the main reinforcement 2 and the stirrup 3 are bound by iron wires (not shown in the...

Abstract

The invention discloses a preformed steel bar concrete special-section post, belonging to construction technique, comprising concrete, main bar and hoop reinforcement, while its section is in cross shape, I-shape, or gear shape. Compared with square post and tube post in same section, the special-section post changes the geometry physical character of section, improve section rigidity, increase the side area of post circumference, and improve the friction resistance and horizontal bearing force of post.

Description

technical field [0001] The invention relates to a prefabricated reinforced concrete pile with a special-shaped section, which belongs to the field of construction. Background technique [0002] The prefabricated reinforced concrete static pressure piles currently used in the construction field have square sections (square piles) and circular hollow sections (pipe piles) according to the cross-sectional shape, which are also currently used more. However, square piles and pipe piles also have shortcomings. The disadvantages of square piles are: because the cross-sectional area is not too large, the area around the pile is relatively small, and the frictional resistance of the pile side is also relatively small, so the number of piles per unit project is relatively large; The disadvantages are: the section stiffness is small, the pile body may crack and the pile will be broken during the pile pressing process, and the pile side friction resistance is relatively small.
