Inwards-concave metal plate unit based on plane curtain wall external hanging

Abstract

The invention discloses an inwards-concave metal plate unit based on plane curtain wall external hanging. According to the inward-concave metal plate unit based on the plane curtain wall external hanging, when a plane component type curtain wall is installed, the metal plate unit penetrates through an interlayer panel directly from a main body structure, and a switching system which is high in outward-hanging bearing capacity and capable of being adjusted in a three-dimensional mode is provided; the inwards-concave type perforated metal plate unit is formed by machining, assembling and forming all aluminum profile components, modeling metal plates and fasteners in a factory, the inwards-concave type perforated metal plate unit is integrally hung on the outwards-protruding switching system on site through a hanging system, and an anti-seismic, anti-disengaging and anti-sideslip device is further arranged. The inward-concave metal plate unit based on the plane curtain wall external hanging has the advantages of being complete and attractive in effect, reasonable in structural stress, safe, reliable, excellent in waterproof performance, simple and convenient to machine and install, simple and feasible in quality precision control, high in adjustability, good in replaceability, high in applicability, good in economical efficiency and the like, and has good popularization and application prospects in the field of building curtain walls.

Description

technical field [0001] The invention relates to a concave metal plate unit based on the external hanging of a plane curtain wall, which is applied to the design and construction of the external decorative strip or frame of the curtain wall in the field of building curtain walls. Background technique [0002] At present, there are more and more personalized requirements for building facades, architectural design requirements for the form and function of facades are becoming more and more diverse, and the external decorative shapes of building curtain walls are different in shape and size requirements are getting larger and larger. The requirements for the adaptability of curtain wall decoration design and installation, connection reliability and replaceability and maintainability are also getting higher and higher. [0003] The traditional external decorative strips or frames of the curtain wall are usually connected on the curtain wall keel by connectors, and the aluminum pr...

Problems solved by technology

[0003] The traditional external decorative strips or frames of the curtain wall are usually connected on the curtain wall keel by connectors, and the connected aluminum profile decorative strips or large-size composite aluminum profile decorative frames, or the decorative frame formed by all metal plates, these methods need to be on the curtain wall keel To bear the load of the plane curtain wall, but also to bear the load of the cantilevered large-size decorative strip or decorative frame, often resulting in insufficient force on the keel; the joints are often small in size due to the size limit of the curtain wall joints, and the decorative frame is under the action of a large wind load Large in-plane deflection will occur with the connectors, and the sealant between the decorative frame and the plane curtain wall panel will be pulled apart, resulting in rainwater leakage; in addition, the traditional decorative frame adopts the method of component curtain wall. The horizontal and vertical components are installed on site sequentially, and its quality and accuracy are difficult to guarantee

The traditional method of hanging large decorative strips or decorative frames on the outside of the curtain wall cannot meet the requirements of large size, changeable shape, safe and reliable connection, beautiful appearance, and excellent quality at the same time, and has poor adaptability, which is not conducive to replacement and maintenance. Construction and maintenance bring a lot of troubles, which cannot meet the needs of the growing technology of the building curtain wall industry
