Embodiment Construction

[0040] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0041] Figure 1 to Figure 3 It is a detailed drawing of each component that forms the invention.

[0042] Such as figure 1 As shown, it is a prefabricated assembled column, and a piece of steel bar is reserved at the end of the prefabricated column (the length of the steel bar should not be less than 40 times the diameter of the steel bar or the length of the longitudinal bar is not less than 500mm), and the reserved steel bar is the longitudinal bar of the column. The end of the prefabricated column is made into a stepped shape. The prefabricated column is poured with ordinary Portland concrete and cured for more than 28 days under standard curing conditions. The end face of the column has a certain roughness.

[0043] Such as figure 2 As shown, in order to support the L-shaped st...

Abstract

The invention discloses a quick concrete assembly type joint and a method for constructing the same. The quick concrete assembly type joint comprises a first prefabricated column and a second prefabricated column. The ends of the first prefabricated column and the second prefabricated column are integrally connected with each other, a connection zone is arranged between the ends of the first prefabricated column and the second prefabricated column, two longitudinal bars which are positioned in the connection zone are reserved at the ends of the first prefabricated column and the second prefabricated column, and the reserved longitudinal bar positioned on the first prefabricated column and the reserved longitudinal bar positioned on the second prefabricated column are staggered from each other and are overlapped on each other in the connection zone; stirrups are arranged on the reserved longitudinal bars, form frames are arranged on the outer side of the connection zone, and grouting openings and exhaust openings are formed in the form frames; concrete connection sections which are integrated with formworks are poured in the form frames. The quick concrete assembly type joint and the method have the advantages of short forming time, high strength, good toughness, zero maintenance and simple and convenient construction processes. Besides, the quick concrete assembly type joint ismainly applied to connecting prefabricated assembly type concrete columns.

Description

technical field [0001] The invention relates to the field of civil construction engineering, in particular to a novel fast concrete assembly type node. Background technique [0002] Prefabricated concrete structures have significant advantages such as saving materials, reducing energy consumption, being conducive to environmental protection, improving building quality, shortening construction period, improving labor productivity and comprehensive economic benefits, and promoting construction industrialization. At present, in developed countries in Europe and the United States, prefabricated concrete structures have become the main form of new buildings. Prefabricated concrete structures can be divided into two types: assembled integral type (post-cast integral type) and fully assembled type. In general, the assembled monolithic precast concrete structure is prone to damage at the joints, and the damage is likely to appear at the joints first, so the reliability of the assem...
