Problems solved by technology

This method is suitable for medium and high-rise shear wall structures. In large-scale frame structures, the prefabricated exterior walls need to be connected with structural beams and columns after the construction of the main frame. The connection node environment is more complicated and the construction is more difficult. The integrally assembled exterior wall The connection technology cannot fully meet the node connection requirements

Embodiment 1

[0030] see figure 1 , this embodiment discloses a prefabricated building concrete beam-column steel composite connection node structure, which is used to install a prefabricated component 1 on a building structure 2. The structure 2 is temporarily connected through a composite steel connection node, and the prefabricated component 1 and the structure 2 are connected through a concrete permanent connection node 3 . In the present invention, the prefabricated component 1 is installed on the structure 2 by combining the combined section steel connection node, that is, the temporary node and the permanent node. On the premise that the overall structure 2 composed of the prefabricated component 1 and the structure 2 is safe and stable, it realizes convenience, Efficient construction greatly improves the assembly speed of prefabricated components 1, shortens construction time, and saves a lot of manpower and material resources.

[0031] In this embodiment, the prefabricated compone...

Embodiment 2

[0044] see figure 2 , in this embodiment, the composite section steel connection node between the lower end of the prefabricated component 1 and the structure 2 is similar to the composite section steel connection node between the upper end of the prefabricated component 1 and the structure 2 in the structure 2, using metal connectors 4c and the first and second metal embedded parts 5c and 6c, because the metal connector 4c has excellent mechanical properties and cross-sections of different shapes, it has a high tolerance for positional deviation between the prefabricated component 1 and the structure 2, It has strong universality and can realize the safe, convenient and efficient connection between the prefabricated component 1 and the structure 2. The difference between this embodiment and the first embodiment lies in that the positions of the first and second embedded metal parts 5c and 6c are different, and there is no horizontal connecting portion at the lower end of the...

Embodiment 3

[0050] see image 3 , this embodiment is applicable to the connection node between the prefabricated component 1 and the roof layer of the structure 2 . The difference between this embodiment and embodiment one is as follows:

[0051] The upper end of the prefabricated component 1 has a horizontal connection portion 1a, which rests on the cantilever beam 2a at the top of the structure 2, and the horizontal connection portion 1a extends horizontally to the inside of the structure 2 for a certain distance The first embedded metal part 5d is pre-embedded on the lower surface of the extension section of the horizontal connection part 1a into the structure 2, and the second embedded metal part 6d is pre-embedded on the vertical inner surface of the structure 2, so The metal connector 4d is selected from connecting angle steel, and the metal connector 4d is respectively connected with the first and second metal embedded parts 5d and 6d.

[0052] When the metal connector 4d is conn...

Abstract

The invention relates to the technical field of building construction, and provides a prefabricated building concrete beam column profile steel connection node structure and a method. The technical problems that an existing prefabricated outer wall needs to be connected with a structural beam column after construction of a main framework is completed, a connection node is complex, and construction difficulty is high are solved. The connection node structure is used for installing a prefabricated member onto a building structure. At least two positions of the prefabricated member in the vertical direction are temporarily connected with the building structure through combined profile steel connection nodes, and the prefabricated member and the building structure are connected through concrete permanent connection nodes. The prefabricated building concrete beam column profile steel connection node structure can adapt to various structures through the combined profile steel connection nodes, high tolerance to position deviation between the prefabricated member and the building structure is achieved, and the prefabricated member and the building structure are connected safely, conveniently and efficiently in combination with the concrete permanent connection nodes.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a structure and method for a prefabricated building concrete beam-column steel composite connection node. Background technique [0002] At present, there is no mature connection technology and relevant construction experience between prefabricated components and structural beams and columns in China, and the technology of integrally assembled exterior walls can be used for reference. [0003] In the construction of integrally assembled external walls, usually, angle steel, bolts and diagonal braces are used for temporary fixation first, and then the integral internal formwork is cast-in-place concrete to form an integral connection. This method is suitable for medium and high-rise shear wall structures. In large-scale frame structures, the prefabricated exterior walls need to be connected with structural beams and columns after the construction of the main frame. The conne...
