Green fabricated concrete prefabricated component and preparation method thereof

Abstract

The green assembly type concrete prefabricated part comprises a lower side edge beam, a balcony plate and an upper side edge beam, the balcony plate and the lower side edge beam are integrally poured to form a bottom module, the surface of the balcony plate is flush with the surface of the lower side edge beam, and joint bar holes and lock holes are formed in the surface of the lower side edge beam. An internal thread sleeve is pre-embedded in the lock hole, a connecting through hole is formed in the upper side edge beam corresponding to the internal thread sleeve, and a connecting steel bar is arranged at the bottom of the upper side edge beam corresponding to the joint bar hole; the lower side edge beam and the upper side edge beam are locked and fixed through connecting bolts penetrating through the connecting through holes and the inner threaded sleeves and are bonded and fixed through connecting steel bars stretching into the joint bar holes. The invention further discloses a preparation method, the formwork is built on the formwork platform to prepare the bottom module and the upper side edge beam, the bottom module and the upper side edge beam are both prepared in an inverted mode, and the bottom module and the upper side edge beam are conveyed to a construction site to be assembled and used. The mold is easy to store and prepare, low in cost and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a green prefabricated concrete component and a preparation method. Background technique [0002] Prefabricated buildings are a means of producing "parts" such as beams, wall panels, laminated floors, stairs, balconies, etc. in the factory, and then transporting them to the construction site, and then assembling them to form a building. Through factory prefabrication, it can reduce the Dust and noise in the on-site environment is a necessary way for green development and has been vigorously promoted. [0003] In existing residential buildings, the design floor height of the residence is generally between 2.8-3.0m. At present, cantilevered balconies are mostly used. Due to the high cross-section height of the beams at the bottom of the balconies, the lighting of the balconies is blocked, which greatly affects the building's ability to adopt, and does not conform to...

AI Technical Summary

Problems solved by technology

[0004] However, because the balcony slab is designed in the middle of the cantilever beam, the irregularity of the prefabricated balcony structure is directly aggravated, and the vertical section is T-shaped, so it cannot be formed on the mold table, and a steel mold with a special-shaped structure needs to be customized first. , and then prepare the prefabricated balcony, the mold cost will be greatly increased

At the same time, due to irregular components and the inability to effectively use the formwork, the quality of prefabricated balconies is generally poor and cannot meet the requirements of inspection and acceptance

In addition, prefabricated balconies with special-shaped structures are difficult to stack and easy to cause concrete cracks and damage during the process of stacking and transporting them to the project site. If they are placed individually, they will occupy a large area of ​​the site and greatly increase the transportation cost
