Pile body corner protection sleeve and prefabricated building structure

Abstract

The invention provides a pile body corner protection sleeve and a prefabricated building structure. The prefabricated building structure comprises the pile body corner protection sleeves and prefabricated piles. Each pile body corner protection sleeve comprises a pile sleeve used for being arranged on the peripheral wall of each prefabricated pile in a sleeving mode, a notch is formed in the end of the pile sleeve, and the ends of the pile sleeve are bent in the axis direction of the pile sleeve to form inflection edges. According to the pile body corner protection sleeve provided by the invention, the rigidity is improved, when external force acts on the pile body corner protection sleeve, the pile sleeve sinks towards the axis direction of the pile body corner protection sleeve or the distortion degree is reduced, the pile body corner protection sleeve can tightly wrap the ends of the prefabricated pile and sleeve the peripheral wall of the prefabricated pile, concrete at the ends ofthe prefabricated pile is better pressed, the concrete is prevented from being broken and falling off, and the reliability and durability of the prefabricated building structure are improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a pile corner protector and a prefabricated building structure. Background technique [0002] Prefabricated building structures refer to all kinds of piles that are prefabricated and transported to the construction site, including prefabricated piles formed by pouring and hardening concrete, and pile corner protectors that are set at the ends of prefabricated piles. The existing pile body corner protector is made by bending and rolling a lightweight thin plate made of metal material to form a cylindrical structure. The pile body corner protector has low rigidity and poor deformation resistance, especially in the process of transporting the pile body corner protector, the force acting on its side will cause the side wall to sag, twist and other undesirable deformations, resulting in The pile body corner protector cannot be tightly wrapped on the end of the prefabricated pile...

AI Technical Summary

Problems solved by technology

The pile body corner protector has low rigidity and poor deformation resistance, especially in the process of transporting the pile body corner protector, the force acting on its side will cause the side wall to sag, twist and other undesirable deformations, resulting in The pile body corner protector cannot be tightly wrapped around the end of the prefabricated pile

When the prefabricated building structure is pressed into the soil layer by the pile driver, the deformed pile body corner protector cannot be tightly sleeved on the surrounding wall of the prefabricated pile, and the concrete at the end of the prefabricated pile is broken and fallen off, which reduces the reliability and durability of the prefabricated building structure sex
