High capacity vertical member for use with modular scaffolding

a vertical member and modular technology, applied in the direction of scaffold connections, building scaffolds, building aids, etc., can solve the problems of incompatibility of above-described systems, too heavy for workers to carry, and the frame made of 1, inch diameter tubes, etc., to achieve the effect of improving the load carrying capacity of the vertical member

Benefits of technology

"The present invention relates to a modular scaffolding system that includes vertical members with a reduced diameter top section and a securing rosette for load bearing. The top section also has an outer tubular reinforcing sleeve to improve load carrying capacity. The bottom section forms a spigot for connection to another vertical member. The invention also includes a locking collar with locking slots and a receiving slot for inserting a scaffold leg. The technical effects of the invention include improved load carrying capacity, secure connection between vertical members, and flexibility in the insertion of scaffold legs."

Problems solved by technology

Frames are typically not used in this type of modular system in that frames made of 1.90 inch diameter tube and of a typical width of approximately 5 feet, are too heavy to be easily carried by a worker.
Typically, the above-described systems are not inter-compatible.

Embodiment Construction

[0039]As indicated in the background of the invention, scaffolding systems, particularly for industrial applications, require substantial load-carrying capabilities, and as such, support posts are often used where the outer diameter of the support posts is approximately 1.90 inches. These support posts are easily carried by a single worker, and the support posts typically have a number of connection points at pre-determined positions intermediate the length of the support post. These support posts are inter-connected by ledgers such as ledgers 10 and these types of systems also include diagonal brace-type members of the appropriate length. With such a post system, the modular spacing between posts is effectively fixed by the connecting components.

[0040]As shown in FIG. 1, frame systems such as frames 6 can also be connected in a similar manner to the connection between the scaffold posts indicated as 4. If the same connecting components used for the scaffold post system are used in ...

Abstract

A vertical member of a modular scaffolding system includes a securing rosette provided in an upper section having a reduced diameter to provide a pre-determined modular connection. The vertical member includes an elongate intermediate section forming the majority of the vertical member of a first diameter greater than the reduced diameter. The intermediate section at a lower edge includes an integral spigot of the reduced diameter. A reinforcing sleeve is fixedly secured to the upper section above the rosette and forms a spigot receiving socket. The vertical member has higher capacity due to the larger diameter intermediate section while maintaining modularity of the scaffolding system.

Description

RELATED APPLICATIONS[0001]This is a continuation-in-part of pending U.S. application Ser. No. 12 / 230,522 entitled Modular Scaffold System filed Aug. 28, 2008 which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present application related to a high capacity vertical member compatible with modular scaffolding and the high capacity vertical members in combination as part of a modular scaffold system.BACKGROUND OF THE INVENTION[0003]Scaffolding systems can be generally divided into three major types of systems, namely tube and clamp systems, frame and cross-brace systems, and modular systems. The tube and clamp systems are extensively used in the industrial sector and are easily adapted to cope with confined spaces where there are many obstructions such as pipes, stairways, structural steel frameworks, etc. These systems require considerable expertise to erect correctly, and are almost always erected by experienced professional scaffold erectors. With the more rece...
