Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, a new type of precast concrete component lifting point embedded parts system, the system includes embedded parts (1), anti-split steel bars (2), pull-out steel bars (3), horizontal U-shaped steel bars (4) , distributed steel bars (5), and end plates (6). This system can be used in prefabricated concrete components of prefabricated structures, and can be poured and formed together with prefabricated concrete components. It can be used alone or together as a group of lifting points.

[0030] Such as figure 2 As shown, the embedded part (1) is made of high-strength steel, grooves are set on the upper and lower sides of the embedded part, and the end plate (6) is welded to the end of the embedded part to increase the adhesion between the embedded part (1) and the concrete. knot performance.

[0031] Such as image 3 As shown, the anti...

Abstract

The invention discloses a novel prefabricated concrete member hoisting point embedded part system, and relates to the technical field of assembly type structures. The system comprises an embedded part, anti-pulling steel bars, anti-splitting steel bars, horizontal U-shaped steel bars, distribution steel bars and the like. The embedded part is made of high-strength steel, grooves are formed in theedge of the embedded part, end plates are arranged at the tail of the embedded part, and the bonding performance between the embedded part and a prefabricated member is improved. The anti-pulling steel bars penetrate through holes in the embedded part and are arranged in the longitudinal direction of the embedded part, and the anti-pulling bearing capacity of the embedded part is improved. The anti-splitting steel bars penetrate through the holes in the embedded part and are perpendicular to the embedded part, and the shear capacity of the embedded part is improved. The horizontal U-shaped steel bars are arranged around the embedded part and perpendicular to the embedded part, and the performance of the embedded part under the oblique tension is improved. The distribution steel bars are arranged around the anti-splitting steel bars and perpendicular to the anti-splitting steel bars, and the integrity between the system and the prefabricated member is improved. The embedded part systemis excellent in stress performance, suitable for various hoisting modes of large prefabricated concrete members and good in engineering application prospect.

Description

technical field [0001] The invention relates to the technical field of prefabricated structures, in particular to the technical field of hoisting prefabricated concrete components. Background technique [0002] Prefabricated buildings refer to buildings assembled from prefabricated parts and components on site, which have many advantages such as saving resources, reducing labor force, environmental protection, improving production efficiency, shortening construction period, standardized production, and improving the comprehensive economic benefits of buildings. In recent years, with the strong support of governments at all levels, prefabricated buildings have developed rapidly. [0003] The parts and components of the prefabricated structure are prefabricated in the factory and transported to the construction site for hoisting by lifting equipment. Therefore, the embedded parts of the lifting points installed on the prefabricated parts are particularly important for the hois...
