Problems solved by technology

[0004] 1) The rotation and deformation of the wall panels are limited, and the wall panels are easily damaged when the deformation of the main frame is large;
[0005] 2) The structure is relatively complex, requiring a variety of special components, the structure is complex, and there are many parts;
[0006] 3) Auxiliary installation tools need to be processed;
[0007] 4) The on-site welding workload is heavy, the degree of engineering assembly is low, and the construction efficiency is low
[0008] 5) The installation is complicated, the construction operation is cumbersome, and the installation accuracy is high;
[0009] 6) The mechanical performance of the joints is poor, and the contribution of the external wall panels to the overall stiffness of the structure is unknown, which affects the calculation of the seismic action of the structure

Embodiment 1

[0048] A steel frame connection node with ALC external wall panels, that is, in the steel frame connection node with ALC vertical external wall panels:

[0049] An ALC external wall panel I1 is equipped with several connecting pieces 2 .

[0050] An ALC external wall panel I1 is connected with the upper and lower I-beams in the building frame. Wherein, the upper one is marked as the upper I-shaped steel beam 3, and the lower one is marked as the lower I-shaped steel beam 5, and the two are parallel to each other.

[0051] The connector 2 includes a vertical plate 201 and a bottom plate. The two sides of the bottom plate are respectively an upper plate surface and a lower plate surface, and the lower plate surface is marked as an E surface 223 . The vertical plate 201 is vertically fixed on the upper surface of the bottom plate. The vertical plate 201 divides the upper surface of the bottom plate into two parts, one side of the vertical plate 201 is the C surface 2021 , and ...

Embodiment 2

[0057] In the connection node of the steel frame with ALC horizontal external wall panels, the same connection piece as that in Embodiment 1 is used.

[0058] One ALC external wall panel II7 is equipped with several connecting pieces 2 .

[0059] An ALC external wall panel II7 is connected with two left and right rectangular steel columns 6 in the building frame.

[0060] The side of the rectangular steel column 6 facing the ALC external wallboard II7 is designated as the F side 603 . The facing faces of the two rectangular steel columns 6 are marked as G faces 604 .

[0061] Several screw rods III601 are welded on the G surface 604 . The number of the screw rods III601 is the same as the number of the connectors 2 .

[0062] During assembly, a rectangular steel column 6 is equipped with at least two connecting pieces 2 . The C surfaces 2021 of these connectors 2 are in contact with the F surfaces 603 of the rectangular steel columns 6 . The A surface 2011 of these connec...

Abstract

The invention discloses a connection joint of a steel frame with an ALC external wall panel based on an existing external wall panel and steel structure connection device and a construction technologythereof and a comprehensive analysis on the advantages and problems of traditional connecting parts. The novel connection device very high in assembly degree, good in mechanical property and rapid and convenient in operation is provided for vertical and horizontal external wall panels.

Description

technical field [0001] The invention relates to the field of prefabricated buildings. Background technique [0002] ALC sheet (Autoclaved Lightweight Aerated Concrete, ALC) has good properties such as light weight, environmental protection, heat preservation, heat insulation and easy assembly. However, due to the complex connection technology between wall panels and structural components, cumbersome construction operations, poor mechanical performance of joints, low degree of assembly, and easy leakage between wall panels, ALC exterior wall panels are particularly important in projects. However, the utilization rate in high-rise building structures is extremely low, which limits the popularization and application of ALC wall panels to a certain extent. [0003] At present, the problems existing in the connection nodes between wall panels and steel structures are: [0004] 1) The rotation and deformation of the wall panels are limited, and the wall panels are easily damaged...
