发明名称 Adjustable scaffold and walkboard ladder holder
摘要 An adjustable universal scaffold bracket and walkboard ladder holder that absolutely prevents scaffold collapse or disattachment from a building and absolutely prevents a ladder placed against a walkboard from slipping sideways. A safety scaffold and bracket is provided with a safety walkboard with rails that also contains a positive means of preventing ladder slip. Vertical supports can attach top and bottom to the building or work under construction. Hold brackets that can be raised or lowered slide up and down the vertical supports. A walkway sits on the hold brackets and is positively held in place by pins. The hold brackets can be equipped with vertical arms in the front so that posts can be place on them to form a place to put a guard rail. In addition a ladder can be optionally leaned against the walkway and secured by additional stay bolts into the walkway to prevent horizontal slipping.
