Pre-stressed concrete solid square pile production device

Abstract

The invention discloses an anti-seismic prefabricated concrete solid square pile which comprises main reinforced bars, hoop reinforcements, anchoring bars, pile caps and concrete. A cross section main body of a pile body is square; the main reinforced bars are formed by sequentially permutating and combining prestress main reinforced bars and general main reinforced bars and penetrate through the pile body along the longitudinal direction of the pile body; the hoop reinforcements are arranged on the outer edges of the main reinforced bars and are spirally squared; the pile caps are respectively arranged at two ends of the pile body and consist of end plates and skirt edges; the main reinforced bars and the hoop reinforcements are connected by welding or binding to form a steel reinforcement cage; two ends of the prestress main reinforced bars are fixedly arranged on the end plate by riveting or using a bolt connecting mode; the general main reinforced bars are separated from the end plate and are shorter than the prestress main reinforced bars; and the anchoring bars are respectively arranged at two ends of the pile body. The anti-seismic prefabricated concrete solid square pile with the structure simultaneously has high press bearing capacity, tensile bearing capacity, shear bearing capacity and flexural bearing capacity and is a concrete solid square pile suitable for industrial mechanical production and is used for high seismic fortification intensity.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 12, 2011, an application number of 2011102311054, and a title of "Anti-seismic Precast Concrete Solid Square Pile and Its Production Method". technical field [0002] The invention belongs to the field of building material production. The invention relates to a production equipment of a prefabricated concrete solid square pile, in particular to a production equipment of a prestressed concrete solid square pile. Background technique [0003] Prestressed high-strength concrete pipe piles have developed rapidly in my country since the 1990s. The concrete strength grade is as high as C80. It is formed by centrifugal technology, atmospheric pressure steam curing (constant temperature is usually 80 ℃ ~ 85 ℃) and high pressure steam curing system (constant temperature The temperature is usually around 180°C, 0.95-1.0MPa), from concrete mixing to prestressed high-...

AI Technical Summary

Problems solved by technology

[0012] The secondary purpose of the present invention is: in order to solve the problems of brittle fracture of prestressed high-strength concrete pipe piles and insufficient horizontal bearing capacity of pile foundations, overcome the large amount of steel used in prefabricated solid square piles or cast-in-situ piles, low production efficiency, and insufficient sand and gravel resources. Due to problems such as efficient utilization and difficult quality control, on the basis of the existing reinforcement design and production process of solid square piles, a design with high vertical bearing capacity and at the same time increases the horizontal bearing capacity of the pile foundation to meet the structural seismic design requirements Anti-seismic Precast Concrete Solid Square Pile
