Description

Technical Field

[0001] The utility model relates to the technical field of connection between curtain walls and steel structures in building construction, in particular to a connection structure between a frame-type curtain wall and an arc-shaped steel structure. Background Art

[0002] In recent years, with the continuous development of the construction industry, some buildings whose main functions are commercial streets, museums or exhibition halls have relatively high requirements for their external shapes. In order to pursue beauty and artistry, an arc-shaped top structure is usually set. In this structure, the connection between the curtain wall and the arc-shaped steel structure is a more difficult problem in the industry. At present, two methods are usually used: conventional welding fixation and welding fixation through adapters. The conventional welding mode is to use channel steel and main pipe for direct welding. This method has the problem of too small welding contact surface and difficult to fix firmly, which ultimately affects the overall verticality and flatness of the curtain wall. However, due to the relatively conventional approach, it can meet the requirements of verticality and flatness under the operation of some experienced welding workers, which makes the operation efficiency low and requires a large number of senior welders to operate, increasing the construction cost. Another approach is to make the top buried plate into an arc and weld it directly to the steel structure. This method will cause the overall heat deformation of the steel structure and affect the bearing capacity of the steel structure. At the same time, the welding deformation has a certain impact on the verticality and flatness of the curtain wall structure, and the actual measured qualified rate cannot be guaranteed.

The embedded plate 1 is a steel plate, and a connecting hole 5 is provided on the embedded plate 1. The connecting member 2 is a U-shaped bolt, which is sleeved on the arc-shaped steel beam 4. Both ends of the U-shaped bolt pass through the connecting hole 5 and are fixedly connected by nuts, thereby realizing a quick connection between the embedded plate 1 and the arc-shaped steel beam 4. The connecting hole 5 is specifically a waist-shaped hole.

[0018] A plurality of reinforcing rib plates 7 are provided between the buried plate 1 and the arc-shaped steel beam 4. The shape of the reinforcing rib plates 7 matches the curvature of the arc-shaped steel beam 4. In this embodiment, the reinforcing rib plates 7 are arc-shaped steel plates, and two reinforcing rib plates 7 are provided. One end of the reinforcing rib plate 7 is fixedly mounted on the top surface of the buried plate 1 by welding, and the other end of the reinforcing rib plate 7 is fixedly mounted on the arc-shaped steel beam 4 by welding.

The embedded plate 1 can also be fixed and welded on site to ensure the verticality of the channel steel installation, and further ensure the verticality of the vertical curtain wall keel 6 installation. In another embodiment, the transfer fixture 3 includes a fixing seat 30 fixedly installed on the bottom of the embedded plate 1 by welding, a transfer rod 31 hingedly installed on the fixing seat 30, and a fastening bolt 32 for fixing the transfer rod 31 and the fixing seat 30, and the vertical curtain wall keel 6 is fixedly connected to the transfer rod 31.
