Abstract

Mullion connection design using a connection clip structurally engaged with a mullion without a hole and a fastener penetrating into the mullion surface for resisting wind load reactions. 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 of 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 can't 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

Holeless curtain wall straight connection system

The invention relates to an external curtain wall connection design, which is applied to a solid material straight or crack straight material condition.

The external curtain wall system consists of three main components, one is the wall panel, which provides weather protection; the other is the straight material, which provides the support of the wall panel; the third is the straight material connection system, which provides The material is connected to the structure of the structural elements of the building. Due to the large gap between the acceptable construction tolerances of the curtain wall and the acceptable construction tolerances of the building structural elements, the straight connection system must be designed to absorb the building tolerances of the building structural elements in three directions (eg on / Lower, inner/outer and left/right). The most difficult to adjust direction is up/down due to the following factors: (a) tolerance due to static load deflection of the joist (eg 12.7 cm or 0.5 inch); (b) due to cement board Tolerance (eg 3.2 cm or 0.125 inch); (c) tolerance due to floor tilt from side to side (eg 0.1 degree); (d) due to floor height tolerance (eg 3.2 cm or 0.125 inch per layer)累积) Cumulative height tolerances; (e) Additional required on-the-job functions, which are deflections between floors (eg 19 cm or 0.75 inches) with solidified cement slabs and/or solidified cylinders (3.2 cm per layer or Long-term constant load creep in 0.125 inches. The straight material connection system basically consists of a connecting piece on each side of the straight material, and the straight material is kneaded with a structural bridge through a straight material pipe connected between the connecting piece and the building structural element. In the prior art, the direct connection system used to adjust the construction tolerances in the up/down direction has the following problems:
(1) For solid vertical straight feed systems, a vertical slot is provided in a straight connector or straight mesh (US 6,591,562 or US 6,598,361). The length of the elongated holes is designed to accommodate the construction tolerances of the structural elements of the building, the effects of live load deflection between floors and long-term constant load creep, and are stated in the job description. Out-of-tolerance conditions often occur at certain locations without the engineer's consent and compromise with the variant. If the conditions beyond the tolerance are still established and leave an undue space causing deflection between floors, the representative conditions are not checked and compromised in the structural integrity of the service conditions. In addition, the wind pressure reaction creates a tolerance condition for the straight material, which creates an overpressure condition in which the straight material is located at the edge of the elongated hole. In an advanced design, the overpressure condition is negligible except that the narrow bores loaded in the straight mesh are transferred to the blocks in the straight tube. In addition, according to the conditions of the contact surface, the straight material is too tight to perform the sliding required for the deflection between the floors, and because of the danger of the nut and the loose nut, the loose material will damage the structure of the connection system. Soundness. Therefore, for this design, when it is difficult to manage execution, the tightening torque will be indicated. In general, in this field, proper installation of narrow holes is impossible to manage and determine.
(2) For a cracked straight material system to be used, the straight material connection with the upper/lower adjustable setting 系 is fastened to the straight material near the end of the straight material. When the unit is adjusted in two horizontal directions, the last up/down adjustment can be performed using the adjustable setting. This connection design is not affected by flexing or solidification between floors. However, the amount of adjustment will affect the length of the joint and can be designed for the maximum construction tolerances in the job description. As discussed in the design of the narrow hole, structural compromise conditions with over-adjustment due to out-of-tolerance conditions are almost negligible in this field.
(3) For example, with a 0.1 degree floor tilt tolerance on a 30.48 meter or 100' width wall, the height tolerance from one side to the other is calculated to be 53.2 cm or 2.094 inches. The existing straight material connection system cannot cause such a large tolerance adjustment without damaging the structural soundness, and the curtain wall support must ignore the slope tolerance of the following slope.
(4) For example, using a 3.2 cm or 0.125 inch floor height tolerance on a 100-floor building, the cumulative height tolerance is 320 cm or 12.5 inches. This system must be designed to absorb this tolerance on each floor.
(5) For example, using a 12.7 cm or 0.5 inch static load deflection, a 3.2 cm or 0.125 inch plate thickness tolerance and a 3.2 cm or 0.125 inch floor height tolerance, the total required for each floor The tolerance is 19 cm or 0.75 inches. Connection systems from curtain wall providers are often designed today with a maximum tolerance of ±19 cm or ±0.75 inches on the market today. In order to design a higher adaptability, it is not necessary to damage the structural integrity or become too expensive. However, with the board contractor, the upper plate thickness tolerance is too tight to be performed, and with the building frame contractor, the upper floor height tolerance is too tight and difficult to perform. Therefore, it is difficult to avoid exceeding the tolerance condition.
Therefore, there is an urgent need for a straight-through connection system that ensures a robust construction of the straight-through connection when a high construction tolerance in the vertical direction is allowed.

In order to achieve the goal of the straight connection design, it can tolerate high construction tolerances in the vertical direction, in accordance with the implementation and description of the present invention, the present invention provides a straight material connection system with vertical tolerances for construction tolerances. Sex, which is independent of other curtain wall functions.
The invention can achieve the following purposes:
1. Provide a straight material connection system that avoids a high construction tolerance without using a narrow hole in the straight material.
2. Provide a straight material connection system that tolerates a high construction tolerance without compromising the structural integrity.
3. A straight feed system is provided that does not use a weir that penetrates the straight tube to allow for the use of a continuous straight tubular space as a contribution to the utility line.

The purpose, technical contents, features and effects achieved by the present invention will be more readily understood by the detailed description of the embodiments and the accompanying drawings.
