Concrete armored joint form that provides one step installation and thermal transfer prevention as well as seating for joint filler

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 installation. Eliminates thermal transfer in low temperature environment to a higher temperature environment through the concrete slab. Provides simple elevation adjustment. 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 plastic 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.

1 - 9 . (canceled) 
     
     
         10 . The concrete armored joint form is comprised of a one step, set in place and leave in place concrete armored joint form that provides thermal transfer prevention along with a seating system which thereby captures the joint fill material. Furthermore, the concrete form is comprised of an adjustability of the steel armor joint to compensate for undulations in the grade or the insulated floor materials. 
     
     
         11 . The concrete armored joint form according to  claim 10 , is comprised of two pieces, including a plastic composite base attached to a plastic upright form and steel armor joint components fitted with headed studs, to provide for anchoring in the concrete slab. The armor joint steel is attached to the plastic upright form which allows for a one step setting and a leave in place installation. 
     
     
         12 . According to  claim 11 , the plastic upright component of the concrete armored joint form provides for a thermal break property, thereby eliminating any thermal transfer between concrete floor slabs. 
     
     
         13 . The plastic upright component according to  claim 12  of the concrete armored joint form is grooved on the top horizontal surface to provide a seating base for the joint fill material. 
     
     
         14 . The concrete armored joint plastic upright component according to  claim 13 , is fitted with armored joint steel and is attached to the plastic upright component by means of comprisable neoprene bolts and nuts. 
     
     
         15 . According to  claim 10 , the armored joint steel is fitted with attached jack bolts which therefore enables a vertical adjustability feature.
