Problems solved by technology

However, there are still some problems and limitations in this connection method, and the node design has also become an important factor restricting the development level of my country's prefabricated structures.
[0004] At present, the connection method of beams and columns of prefabricated frame structures in my country mainly adopts integral cast-in-place. This method has low construction efficiency, difficulty in installing and replacing components, insufficient deformation capacity of nodes, low durability, difficulty in guaranteeing the quality of cast-in-place nodes, and post-maintenance. Difficult, not conducive to energy saving and environmental protection and other shortcomings

Embodiment 1

[0035] Such as Figure 1-4 As shown, this embodiment provides a beam-column connection node of an assembled frame structure, including a prefabricated corbel column 1, a prefabricated beam 2, a high-strength bolt 3, a pressure-bearing steel plate 4 and a nut 5; the prefabricated beam 2 includes a main body and a connecting part , the connection part is located at the end of the main body, integrally formed with the main body, and the cross-sectional area of ​​the connection part is larger than the main body, thereby forming a force application surface opposite to the end surface of the prefabricated beam 2 on the connection part; the pressure bearing steel plate 4 is arranged on the force application surface, The connection part is supported by the corbels on both sides of the corbel column, and the connection part and the corbel column are connected by high-strength bolts 3 , and the ends of high-strength bolts 3 pass through the pressure-bearing steel plate 4 and are tightene...

Embodiment 2

[0037] Such as Figure 1-4 As shown, this embodiment is an embodiment improved on the basis of Embodiment 1, which includes all the content of Embodiment 1, that is, the beam-column connection node of the fabricated frame structure in this embodiment includes all the structures of Embodiment 1 Features, the specific improvements are as follows:

[0038] The prefabricated beam 2 is a T-shaped variable-section beam, that is, the main body of the prefabricated beam 2 and the connection part of the prefabricated beam 2 form a T-shaped integral prefabricated beam 2. The surface dimensions correspond to each other, and the width of the connecting portion corresponds to the width of the prefabricated corbel column 1 .

[0039] Further, there are eight high-strength bolts 3, four of which are distributed on the force-applying surfaces on both sides of the main body, and the high-strength bolts 3 are arranged in rows at equal intervals in the vertical direction.

[0040] Further, a s...

Abstract

The invention discloses a fabricated frame structure beam-column connection node and a construction method and relates to the structural engineering field. The beam-column connection node includes a prefabricated cow-leg pillar, a prefabricated beam, a high-strength bolt, a pressure bearing steel plate and a nut, wherein the prefabricated beam includes a main body and a connecting portion, the connecting portion is located at an end portion of the main body and is integrally formed with the main body, the cross-sectional area of the connecting portion is larger than the main body, a force applying surface opposite to an end surface of the prefabricated beam is formed on the connecting portion, the pressure bearing steel plate is disposed on the force applying surface, the connecting portion is supported by cow legs on both sides of the cow-leg pillar, the connecting portion and the cow-leg pillar are connected through the high strength bolt, and an end portion of the high-strength boltpenetrates through the pressure bearing steel plate and is tightened by the nut. The beam-column connection node is advantaged in that through the prefabricated cow-leg pillar and the prefabricated beam, in a direct field splicing mode, construction of the beam-column connection node is completed, construction efficiency is effectively improved, energy saving and environmental protection are achieved, later maintenance difficulty is low, deformation capacity of the node is further greatly improved, and anti-vibration energy consumption capacity of the node is enhanced.

Description

technical field [0001] The invention relates to the field of structural engineering, in particular to an assembled frame structure beam-column connection node. Background technique [0002] As the country puts forward the development goal of construction industrialization in the 13th Five-Year Plan, prefabricated assembly technology, which is the core of construction industrialization, has developed rapidly in recent years. Compared with the cast-in-place concrete structure, the prefabricated concrete frame structure has the advantages of high efficiency, environmental protection, energy saving, less wet work on site, and easy management. [0003] In the prefabricated concrete frame structure, the beam-column joint connects the beam-column into a whole, plays the role of load transfer and seismic energy dissipation, and is the key of the prefabricated concrete frame structure. At present, the connection method of beams and columns of prefabricated frame structures in my cou...
