Connecting joint of prefabricated hood pitched roof and prefabricated wall and construction method of connecting joint

Abstract

The invention provides a connecting joint of a prefabricated hood pitched roof and a prefabricated wall. A roof wallboard is a prefabricated wallboard meeting design requirements, reserved bar inserting holes are formed in the connecting position of the roof wallboard and a vertical wall, and wallboard steel bars in the reserved bar inserting holes are normally arranged; at least three lifting rings are arranged on the upper surface of the roof wallboard; and vertical steel bars are arranged at the top of the vertical wall, and the reserved bar inserting holes are filled with grouting materials. A mounting method of the connecting joint of the prefabricated hood pitched roof and the prefabricated wall comprises the steps that when a hood pitched roof wallboard is prefabricated, multiple hole die reserved bar inserting holes are formed; when the wall is prefabricated, vertical inserting bars are embedded at the top of the wall according to the distance of the reserved bar inserting holes; the roof wallboard is lifted, after the mounting inclination degree is adjusted, the roof wallboard falls to the top of the wall, and the inserting bars are exactly inserted into the bar insertingholes; and then an inclined support is fixed, joint grouting of the wall and the roof wallboard is carried out, and after the structure connecting strength meets the code requirements, the inclined support is dismounted. The field construction speed is increased, the roof board and the wall are connected conveniently, and the joint is stable.

Description

technical field [0001] The invention belongs to the construction technology of construction engineering, in particular to a connection node between a prefabricated sloping roof and a prefabricated wall and a construction method. Background technique [0002] At present, prefabricated wall prefabricated buildings are more and more used in modern construction projects due to their fast construction speed and high construction safety. This kind of building method is energy-saving and environmentally friendly, and it is recognized by everyone, and more and more appear in people's lives. Due to the slope of the sloping roof, the sloping roof is generally cast-in-situ structure. If the building shape is a sloping roof, the project with a large roof area during construction will have a greater safety hazard when working on the top. The roof formwork support process is also relatively complicated, and the construction efficiency is low. Contents of the invention [0003] The inv...
