Backcut changeover cross beam of unitized curtain wall

Abstract

The invention discloses a backcut changeover cross beam of a unitized curtain wall. The backcut changeover cross beam of the unitized curtain wall comprises a cross beam framework. The upper surface of the cross beam framework is a channel steel junction surface; the left side of the cross beam framework is provided with an aluminum plate skeleton connecting part; the lower surface of the cross beam framework is provided with a changeover cross beam hook; the hooking part of the changeover cross beam hook forms an inclination towards the inner side and along the horizontal direction; and the right side of the cross beam framework is provided with a pressing plate assembly slot. According to the backcut changeover cross beam of the unitized curtain wall, the construction flow of a general curtain wall is changed, i.e. a decoration panel of a cornice is firstly installed, and a working face can be totally spread to engineering to realize cross operation; the cross operation is not limited by the construction sequence, and parallel construction can be performed, therefore, the construction progress is greatly increased. An interlayer backcut changeover cross beam of the unitized curtain wall and a cornice aluminum plate skeleton are combined to form an integral seal, therefore, not only can the functional requirement of the cornice aluminum plate skeleton be met but also the functional requirement that the cornice aluminum plate skeleton is combined with the interlayer backcut changeover cross beam of the unitized curtain wall can be met.

Description

technical field [0001] The invention relates to a transfer beam, in particular to a transfer beam on the opening of a unit curtain wall which can optimize the installation process, and belongs to the technical field of super high-rise building construction. Background technique [0002] The best choice for the super high-rise building envelope is the unit curtain wall. Due to the light weight of the unit curtain wall, strong anti-displacement ability, and overall installation, the unit curtain wall must become the only choice for the outer enclosure structure of super high-rise buildings. Due to the requirements of architectural design, the particularity of the cornice design of the floor beams, and the installation of window cleaning equipment, it is necessary to have an independent unit curtain wall system between floors; this means that once the unit curtain wall between floors is completed If the installation is completed, the construction personnel cannot reach the out...

Problems solved by technology

Due to the requirements of architectural design, the particularity of the cornice design of the floor beams, and the installation of window cleaning equipment, it is necessary to have an independent unit curtain wall system between floors; this means that once the unit curtain wall between floors is completed If the installation is completed, the construction personnel cannot reach the outdoor operation, and the cornice decoration must be installed through the auxiliary equipment of the hanging basket. However, due to the particularity of the cornice shape, the working surface and decorative surface of the hanging basket construction cannot be in place at one time, and the unit The external sealing treatment of the curtain wall also limits the progress and efficiency of the project construction

However, if the cornice veneer is installed first, it will bring a lot of inconvenience to the installation of the interstory unit curtain wall, which is specifically reflected in the fact that the system of the curtain unit curtain wall is not matched, and the joints with the cornice veneer are difficult to achieve sealing treatment
