Embodiment

[0039] In the construction of a 6-story residential building in a pilot project, the cross-sectional size of the prefabricated columns is 600mm×600mm, the cross-sectional size of the prefabricated beams is 400mm×600mm, the concrete layer is made of C30 concrete, and the longitudinal bars and stirrups are all made of HRB400 steel bars , the thickness of the concrete protective layer is 20mm.

[0040] 1. Factory prefabricated part:

[0041] Production of prefabricated columns: 12 vertical bars with a diameter of 25mm are evenly arranged around the column, and in order to install the grouting sleeve, the bottom of the vertical bars is 100mm higher than the bottom of the column, and the top of the vertical bars is also higher than (extruded) the column Top 100mm; Stirrups I with a diameter of 10mm and a spacing of 100mm are evenly arranged along the direction of the vertical bar; four U-shaped steel bars with a diameter of 25mm are arranged on the lower part of the column-beam joi...

Abstract

The invention relates to an edge joint connecting structure and method of a prefabricated integrated type frame column beam, and belongs to the field of prefabricated concrete structure engineering. The edge joint connecting structure of the prefabricated integrated type frame column beam is characterized by further comprising a tensile longitudinal bar, a U-shaped reinforcing steel bar, roughening layers and a concrete connecting layer, the upper connecting steel bar, namely the tensile longitudinal bar and the lower U-shaped steel bar are arranged at the joint portion of a prefabricated column, and right sections of the tensile longitudinal bar and the U-shaped steel bar are both tied with a stirrup I and buried in the prefabricated column. The edge joint connecting method of the prefabricated integrated type frame column beam includes producing the prefabricated column and a prefabricated beam in a factory, respectively arranging the roughening layers, correspondingly binding the tensile longitudinal bar and the U-shaped steel bar on the prefabricated column with a longitudinal bar and a stirrup II on the connecting section of the prefabricated beam corresponding on the construction site, and making the cast-in-place normal concrete connecting layer to realize connection between the column and the beam. Construction is facilitated, the period of construction is shortened, and seismic performance is enhanced.

Description

technical field [0001] The invention belongs to the field of prefabricated and assembled concrete structure engineering, and in particular relates to a node connection structure for assembling an integral frame and a method thereof. Background technique [0002] The construction industry plays a huge role in the national economy. However, there are more and more contradictions in the construction industry: high energy consumption, rising costs, difficulty in guaranteeing construction quality, and dirty and messy construction sites. Low-efficiency and extensive methods It has become unsustainable. In recent years, the industrialization of construction and housing has been vigorously promoted, and efforts have been made to promote the structural upgrading and adjustment of the housing industry. [0003] The so-called housing industrialization is to produce prefabricated concrete components in the factory, and then transport the concrete components to the construction site to...
