subject: How To Extend Scaffold Planks? [print this page] A scaffolding plank for a framework scaffolding or a suspended scaffolding, which has its object to eliminate a clearance in all directions of the scaffolding plank and to detachably mount a stopper at the back of a hook on a lateral member with a one-touch control.
There is comprised of a horizontal plank body 6, a plurality of hooks 9, 10, 11, 12 provided at both front and rear ends of the plank body, a plurality of notches 13, 14a, 14b, 15, 16a, 16b likewise provided at both front and rear ends of the plank body, and a stopper mechanism S provided below each hook to be freely moved in and out, said front hook being provided on the same axis where the rear notch is provided, said rear hook being provided on the same axis where the front notch is provided.
Scaffolding is the one element of any construction project, home or commercial, where builders encounter the greatest risk of injury and/or the greatest potential for safety violations and fines. Trying to resolve how to extend scaffold planks without increasing the risk of an accident or violating the strict codes governing their placement can be an enormous headache unless you know a few basic rules.Have a 'competent person' assess and document the needs of the area for extended scaffolding. A 'competent person' in some states is required to have special licensing, and in others experience with scaffolding set up is enough. What is important is that you keep some form of documentation that the person designated as 'competent' approves each step of the scaffolding assembly.
A scaffolding plank detachably mounted through hooks on a lateral member constituting a framework scaffolding or a suspended scaffolding, comprising a horizontal plank body, a plurality of hooks provided on both front and rear ends of the plank body, a plurality of notches likewise provided on both front and rear ends of the plank body, and a stopper mechanism provided below each hook to be freely moved in and out, the stopper mechanism includes a hollow guide, a stopper slidably inserted into the guide, resilient members interposed between the guide and the stopper to bias the stopper in a hook direction, and a locating member provided at the upper part or side of the guide to hold the stopper at a predetermined position against the resilient members; baseboards erected at both left and right ends of the plank body, said baseboards being detachably held on the plank body through a locking mechanism, the front hook being provided on the same axis where the rear notch is provided, the rear hook being provided on the same axis where the front notch is provided.
Assemble the frame of your scaffolding system. Whether it is mobile or stationary, make sure that the supports for your scaffold boards follow the assembly plans.Lay your first plank across the supports of your platform. Have your competent person check that each plan extends a minimum of 6 inches and a maximum of 12 inches past any support bracket.Extend your scaffolding plank by laying the next plank over it. If the span of your support is 7 feet, your plans must overlap a minimum of 6 inches up to a maximum of 12 inches. If the span of your plank support is 10 feet, the boards must overlap 12 inches.You may provide cleats to additionally connect your extended scaffold planks china again. Ask your competent person to designate that the cleats are provided and used only to prevent the scaffold planks from sliding and not as a means of providing any re-enforcement to the boards at all.
It is therefore a first object of the present invention to provide a scaffolding plank in which when a plurality of scaffolding planks are disposed in a row before and behind, a clearance is not formed between plank bodies adjacent to each other.It is a second object of the present invention to provide a scaffolding plank in which a stopper provided below each hook can be detachably mounted on a lateral member with a one-touch control, and this detachable operation can be done by a single operator.It is a third object of the present invention to provide a scaffolding plank in which a stopper can be locked or unlocked even from top of the scaffolding plank.
For achieving the aforementioned objects, according to the present invention, there is provided a scaffolding plank detachably mounted through hooks on a lateral member constituting a framework scaffolding or a suspended scaffolding, comprising a horizontal plank body, a plurality of hooks provided on both front and rear ends of the plank body, a plurality of notches likewise provided on both front and rear ends of the plank body, and a stopper mechanism provided below each hook so as to be freely moved in and out, the front hook being provided on the same axis where the rear notch is provided, the rear hook being provided on the same axis where the front notch is provided.
According to the above-described configuration, when the stopper is extruded, the lateral member of the framework scaffolding or the suspended scaffolding is held by the hooks and stoppers to prevent the plank body from being floated, and when the stoppers are forcibly moved back, the stoppers release the holding of the lateral member so that the plank body can be raised up.Since the plurality of hooks and notches are provided on both front and rear ends of the plank body, the plank bodies can be disposed in a row before and behind through the hooks and notches.
In this case, since a position for fitting the front hook and a position of the rear notch are coincident with each other on the same line, when the rear scaffolding plank manufacturer is disposed next to the front scaffolding plank, the front hook in the rear scaffolding plank can be moved into the notch in the front scaffolding plank. Therefore, no clearance is present in a joint between two front and rear scaffolding planks.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which preferred embodiments of the invention are illustrated.
