Precast pile with reliable axial-direction stressing performance

Abstract

The invention discloses a precast pile with reliable axial-direction stressing performance. The precast pile comprises main steel bars and a pile body. Special-shaped nuts are arranged at the two endsof the inside of the pile body. Clamping tables are arranged inside the corresponding special-shaped nuts. The special-shaped nuts are connected with the main steel bars through the clamping tables.The outer circles of the special-shaped nuts are increased and are further provided with concave-convex surfaces. The special-shaped nuts are fixedly connected with the corresponding clamping tables.The special-shaped nuts and the main steel bars are welded through the corresponding clamping tables. According to the precast pile with the reliable axial-direction stressing performance, the phenomenon that a nut in a finished product pile cannot bear the tensile force of main steel bars and thus axial movement can be made is avoided, and the problem that the performance of the precast pile bodyis severely changed and thus defective piles are produced can be solved; through research and development improvement of the nut inside the precast pile, the outer circle of the nut can be increased;and moreover, due to arrangement of the concave-convex surface of the nut, stressing of the nut inside the pile can be reinforced, axial movement cannot happen easily, the performance of the precastpile is guaranteed and the defective piles produced accordingly are avoided.

Description

technical field [0001] The invention relates to a prefabricated pile, in particular to a prefabricated pile with reliable axial force performance, and belongs to the technical field of mechanical engineering manufacturing. Background technique [0002] Prefabricated piles are piles of various materials and forms made in factories or construction sites (such as wooden piles, concrete square piles, prestressed concrete pipe piles, steel piles, etc.), and piles are driven into, Press or vibrate into the soil. Prefabricated piles are mainly used in China's construction field, mainly in two categories: concrete prefabricated piles and steel piles. Concrete prefabricated piles can withstand large loads, are strong and durable, and have fast construction speed. They are one of the pile types widely used in China, but their construction has a great impact on the surrounding environment. Commonly used concrete solid square piles and prestressed concrete hollow pipes pile. The stee...
