Description

Technical Field

[0001] The utility model relates to the technical field of keels, in particular to a reinforced curtain wall keel. Background Art

[0002] The keel is an important component of the building system. It is a skeleton used to support and fix decorations, facades, ground or roof structures. The building curtain wall refers to the exterior wall enclosure structure of the building. It does not bear the weight of the main structure of the building, but is hung outside the main structure like a curtain. The design of the curtain wall is to provide good building appearance, thermal insulation, sound insulation, lightning protection, fire protection and other properties. It also has a certain ability to resist wind pressure deformation. When used to support and fix the building curtain wall, it ensures the stability and safety of the curtain wall. The material of the keel is generally steel, aluminum alloy, etc., which usually has high strength and good durability.

[0003] However, curtain wall panels are often large in area and heavy in weight. Ordinary keels may not be sufficient to bear the load of curtain wall panels. At this time, the bearing capacity of the keel needs to be strengthened. Otherwise, it will be difficult to meet the installation requirements of large-area curtain walls, and the compressive resistance is difficult to guarantee, which will pose a huge safety hazard. For this reason, a reinforced curtain wall keel is proposed. Utility Model Content
