Novel prefabricated assembly type shear wall horizontal joint structure and construction method

Abstract

The invention discloses a novel prefabricated assembly type shear wall horizontal joint structure and a construction method, and relates to the technical field of building structure engineering. The four high-strength ribbed longitudinal bars are evenly arranged on the two sides of the prefabricated shear wall, the five hoop-shaped high-strength ribbed steel bars evenly and horizontally surround the four high-strength ribbed longitudinal bars and are perpendicularly distributed in the prefabricated shear wall, and the hoop-shaped high-strength ribbed steel bars and the high-strength ribbed longitudinal bars are connected in a binding mode through binding wires. Inner cavities in the two sides of the prefabricated shear wall are fixedly connected with the square steel tube bundles, H-shaped steel connecting pieces are installed between the upper ends and the lower ends of every two adjacent square steel tube bundles, and the H-shaped steel connecting pieces and the square steel tube bundles are fixed through high-strength bolts. And meanwhile, the safety of the structure can be guaranteed, the building period is shortened, and the connecting mode has great social benefits and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of building structure engineering, and in particular relates to a structure and a construction method of a novel prefabricated assembled shear wall horizontal node. Background technique [0002] The traditional model of cast-in-place concrete structures has obvious defects, and can no longer meet the requirements of the construction industry in the new era for green buildings and efficient construction, while prefabricated buildings are becoming a new type of residential structure system due to their high efficiency and environmental protection characteristics. Including precast concrete residential prefabricated buildings and steel structure residential prefabricated building systems. [0003] However, with the continuous development of prefabricated buildings, the problems caused by imperfect prefabricated building technology have gradually emerged.

Problems solved by technology

[0002] The traditional model of cast-in-place concrete structure has obvious defects, and can no longer meet the requirements of the construction industry in the new era for green buildings and efficient construction. The prefabricated building is becoming a new type of residential structure system because of its high efficiency and environmental protection. Including prefabricated concrete residential assembly building and steel structure residential assembly building system

[0003] However, with the continuous development of prefabricated buildings, problems caused by imperfect prefabricated building technologies have gradually emerged. The assembly site construction of prefabricated concrete prefabricated residential building systems is more difficult, the installation and positioning of prefabricated walls is difficult, and a large number of connections are required. The support is assisted and has great hidden dangers, while the steel structure residential prefabricated building system has problems such as poor fire resistance and acid resistance
