Problems solved by technology

However, the upper slab thickness tolerance is too tight to enforce through the slab contractor, and the upper story height tolerance is too tight to enforce through the building frame contractor
So out of tolerance conditions become unavoidable

Embodiment Construction

[0057] The embodiments of the present invention are described in detail below together with the accompanying drawings. The same reference numerals are used in the drawings and the implementation to represent the same component names.

[0058] In order to better describe the working principle of the present invention, the terms used in the present invention are listed below:

[0059] Mullion: One of several building elements, usually used in a vertical orientation, to structurally support a weather sealing exterior wall panel;

[0060] Straight material connection system: a structural system designed to transfer the reaction forces generated by dead load and wind load on the straight material to a structural support element in the building structure;

[0061] connector clip: a first component of a straight material connection system for transmitting reaction forces on the straight material to a second component of the straight material connection system; and

[0062] Structura...

Abstract

A mullion connection system for resisting wind load reactions using a connection clip structurally engaged with a mullion without a hole or a fastener penetrating into the mullion surface. The connection clip can undergo stress-free vertical sliding relative to the mullion along the entire length of the mullion without impairing the structural connection strength; therefore, the building construction tolerance in the vertical direction is eliminated as a design consideration of the curtain wall system. The design also eliminates the need for pre-fabricating mullion holes for the connection locations. The design does not require the pre-determination of the elevation of the connecting point and thus is most beneficial for a curtain wall renovation project where the available locations in the building structure for structural connection cannot be determined prior to the demolition of the existing wall. The uninterrupted mullion tube cavities can be conveniently utilized for inter-floor distribution of utility lines.

Description

technical field [0001] The invention relates to a connection design of an external curtain wall, which is applied to the condition of solid straight material or cracked straight material. Background technique [0002] The external curtain wall system is composed of three main elements, one is the wall panel, which provides weather protection; the second is the straight material, which provides the support of the wall panel; the third is the direct material connection system, which provides Structural connection of building structural elements. Since there is a large drop between the acceptable construction tolerances of the curtain wall and the acceptable construction tolerances of the building structural elements, the direct material connection system must be designed to absorb the construction tolerances of the building structural elements in three directions (e.g. top / down, inside / outside and left / right). The most difficult direction to adjust is up / down due to: (a) to...
