Transition beam for lower opening of unit curtain wall

Abstract

The invention discloses a transferring cross beam of lower openings of unitized curtain walls. The transferring cross beam comprises a lower transferring cross beam frame. The lower surface of the lower transferring cross beam frame is a grounding U-steel joint face; an aluminium plate framework connecting part is arranged at the left side of the lower transferring cross beam frame; a guide positioning boss is arranged at the upper surface of the lower transferring cross beam frame; the connecting part of the guide positioning boss and the upper surface of the lower transferring cross beam frame is a left hollow stand bar and a right hollow stand bar; and an outer layer drainage channel and an inner layer drainage channel are arranged inside respectively. According to the transferring cross beam of lower openings of the unitized curtain walls, the common construction process of the curtain walls is changed, and the decorative face plate with the cornice is installed firstly. Working plane can be developed entirely to realize cross working and parallel construction can be carried out without the limitation of construction sequence, thus the construction progress is greatly accelerated. The transferring cross beam is combined with the cornice aluminium plate framework by virtue of the lower transferring cross beam frame to form a complete closed opening, so that the function requirement of the cornice aluminium plate framework is satisfied and the function of combination with lower cross beams of interlayered unitized curtain walls is satisfied.

Description

technical field [0001] The invention relates to a transfer beam, in particular to a transfer beam at the lower 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 t...

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
