Framing system of studs and rails connected together by adapter members

Abstract

A framing system (1) comprises track frame elements (3) and stud frame elements (4) which are interconnected at joints (2). The framing system comprises connection means for interconnecting the frame elements (3, 4) on assembly. The connection means comprises an adaptor (10) for a frame element and fixing means for fixing the adaptor to the frame elements. The adaptor conforms to at least part of the profile of at least one of the frame elements. In one case the adaptor (10) is of generally channel profile comprising a web (11) and side flanges (12). The side flanges of the adaptor (10) are engagable in the end of the stud frame element (4) such that the flanges (12) of the adaptor engage with the flanges (8) of the stud frame element (4). Rivets (30) are used to fix the stud frame element (4) to the adaptor (10). Track fixing means comprising a fixing bolt (25) extending to engage with a receiver (26) which is captive in the web (11) of the adaptor (10). The cross section of the stud frame element (4) has full bearing with the track frame element (3) for efficient load transfer.

Description

INTRODUCTION[0001]The invention relates to a structural framing system comprising a number of roll formed metal elements jointed together. Such a framing system may be used to provide a wall such as a partition wall of a building such as a modular building.[0002]Many framing systems of this type are known. Stud and track systems for structural applications must enable load transfer from the top track to the stud and from the stud to the bottom track. This must be achieved without short term settlement or long term creep.[0003]In one current arrangement the stud is located in the track and then fastened in place through the flanges. This provides a simple, site fixable method of construction. However, in use the stud usually sits on the internal radii of the track. Consequently, the connection relies on the restricted shear strength of the fastener. Tolerances are limited by site workmanship and varying settlement can present problems.

AI Technical Summary

Benefits of technology

[0003]In one current arrangement the stud is located in the track and then fastened in place through the flanges. This provides a simple, site fixable method of construction. However, in use the stud usually sits on the internal radii of the track. Consequently, the connection relies on the restricted shear strength of the fastener. Tolerances are limited by site workmanship and varying settlement can present problems. As the frames are not assembled in a controlled environment, the positions of each fastener may not be exactly in line. Consequently, creep may occur locally in some studs when a load is applied to the frame.

[0005]The most structurally efficient of these systems facilitates end bearing of the stud into the web of the track. The use of external clamping mechanisms or specialist equipment however leads to high cost and complexity.

Problems solved by technology

Consequently, the connection relies on the restricted shear strength of the fastener.

Tolerances are limited by site workmanship and varying settlement can present problems.

Consequently, creep may occur locally in some studs when a load is applied to the frame.

This system is impractical because it is slow and difficult to operate and is inflexible.

The use of external clamping mechanisms or specialist equipment however leads to high cost and complexity.
