The utility model content

For the problems referred to above, main purpose of the present utility model is to provide a kind of change of foundation pile cage of reinforcement form, mainly is the arrangement of reinforcement mobile type hollow square pile of various cross-sectional areas master muscle combination configuration in the cage of reinforcement.

The utility model solves above-mentioned technical problem by following technical proposals: a kind of arrangement of reinforcement mobile type hollow square pile, described square pile comprises reinforcing cage, concrete, end plate, described reinforcing cage comprises the first main muscle, the second main muscle and stirrup, the square continuous welding that the stirrup of reinforcing cage is square or has the first rounding or the second rounding is on the described first main muscle and the second main muscle, wherein the cross section of the second main muscle is less than the cross section of the first main muscle, the hollow square pile pile body is square, square four jiaos the first rounding and the second rounding arranged respectively.

In specific embodiment of the utility model, the scope of described the first rounding is 0-35mm, and the scope of the second rounding is 20-35mm, and the first rounding and the second rounding are diagonal and distribute.

In specific embodiment of the utility model, the first main muscle that comprises in the described reinforcing cage and total radical of the second main muscle are 8-32, and the first main muscle and the second main muscle are symmetrical.

Positive progressive effect of the present utility model is: the arrangement of reinforcement mobile type hollow square pile that the utility model provides has the following advantages: the utility model proposes a kind of flexible arrangement of reinforcement type hollow square pile, namely need satisfy the requirement of reinforcement ratio in the hollow square pile adjusts the setting of main muscle, adopt large small bore master muscle combination arrangement of reinforcement, guaranteed main muscle total cross-sectional area, meet the reinforcement ratio requirement, adopt this kind form of reinforcement, except satisfying the reinforcement ratio requirement, realize improving to a certain extent the ductility of hollow square pile outside the flexible arrangement of reinforcement.

The specific embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

Fig. 1 is structural representation of the present utility model; Fig. 2 is the top view of the utility model Fig. 1; Fig. 3 is the schematic cross-section of the hollow square pile of foundation of a specific embodiment of the utility model.As shown in the figure: the utility model proposes a kind of flexible arrangement of reinforcement type hollow square pile, namely need satisfy the requirement of reinforcement ratio in the hollow square pile adjusts the setting of main muscle, adopt large small bore master muscle combination arrangement of reinforcement, guaranteed main muscle total cross-sectional area, meet the reinforcement ratio requirement, adopt this kind form of reinforcement, except satisfying the reinforcement ratio requirement, to a certain degree improve on class the ductility of hollow square pile.

This hollow square pile comprises reinforcing cage 1, concrete 2, end plate 3.Described reinforcing cage 1 comprises the first main muscle 11, the second main muscle 13 and stirrup 12, the square continuous welding that the stirrup 12 of reinforcing cage 1 is square or has the first rounding R1 or the second a rounding R2 is on the described first main muscle 11 and the second main muscle 13, the hollow square pile pile body is square, four jiaos chamfering is respectively the first rounding R1 and the second rounding R2, the scope of the first rounding R1 is (0-35) mm, the scope of the second rounding R2 is (20-35) mm, the first rounding R1 and the second rounding R2 are diagonal and distribute, this stress is eliminated circular arc, so that piling reduces hammering stress in building construction process; The pile body endoporus is circular, and this circular hole forms owing to the centrifuging process moulding.
