All metal leave N place armor joint form with joint fill retention

Abstract

The objective of this invention is to provide ease of application for steel armored joints used in industrial concrete floor construction. It provides one step simple and precise installation. Provides a substrate for joint filler compression. Eliminates the need for wood forms and field welding that produces waste. Elevation adjustment and the ease thereof are achieved by vertical slots cut in the upright. The neoprene bolts are to be tightened when the steel is at the desired elevation. Two part armored joints separate as the concrete contracts during the curing process. Then the joint filler product is applied and retained in a permanent encased condition.

         12 . The All Metal Leave N Place Armor Joint Form with Joint Fill Retention is utilized in the placement of concrete slabs and is a one step, set in place and leave in place armored joint form. The form provides a seating system which thereby captures the joint fill material. The form consists of a sheet metal base with two independent upright pieces attached to the base sheet metal. The uprights and base are attached together to form an inverted “T” Shape. The T Shaped sheet metal is fabricated to house the steel armored joint components. The armor joint steel is attached to the sheet metal form by means of neoprene bolts. The neoprene bolts are designed to compromise during the curing phase of the placement of the concrete slab. The act of compromising of said neoprene bolts allows for the separation of the steel armor joints due to the shrinkage factor of concrete. Once separation of the armor joint occurs, then the joint fill medium can be applied to fill the void created by the separation of the armor joint steel. Furthermore, the form includes a vertical adjustability of the steel armor joint that is independent of the sheet metal base and upright. This provides compensation for elevation inconsistencies in the sub-grade and/or insulated floor materials. 
     
     
         13 . The armored joint form according to  claim 12 , consist of a sheet metal base attached to two sheet metal upright components of which the steel armor joints are attached. The fabricated steel armor joints are fitted with headed studs, to provide for anchoring in the concrete slab. The armor joint components and sheet metal upright will separate during the concrete curing process and therefore expose the metal strip which is attached to one side of the bottom portion of the steel armor joint. This separation will provide the seat (metal strip) to capture and retain the joint fill medium. 
     
     
         14 . According to  claim 12 , the armored joint steel is fitted with threaded nuts and threaded studs (jack bolts) which provides the mechanism enabling the vertical adjustability feature. The jack bolts also provide horizontal stability to the armor joint steel during the placement of the concrete slabs.
