Concrete forming panel having built-in retaining structure for storing loose coupling parts

Abstract

A concrete forming panel has built-in retaining structure for holding loose coupling parts in a safe, secure position when the parts are stored during times of nonuse of the panel. Members on the backside of the face plate of the panel, including but not necessarily limited to bracing or stiffening members of the frame, are provided with webs or wall portions having a series of clearance openings therein. Brush rings are positioned immediately adjacent each opening and have radially inwardly directed resilient bristles that terminate in innermost ends defining a hole aligned with the adjacent opening. Consequently, when a oversized coupling part relative to the brush hole is inserted into such hole, it flexes the bristles and passes through the hole and the adjacent opening in the supporting member to be retained in place in a yieldable, releasable manner by the flexed bristles. In a preferred embodiment, the brush rings are retained in place frictionally on each member by a wedging action between the brush rings and a receiving track on the side of the wall of the member.

1 . A concrete forming panel comprising: 
 a face sheet having a perimeter, a front side for receiving concrete there against, and a back side; and    loose parts retaining structure on said back side at a location spaced inwardly from said perimeter of the face sheet,    said retaining structure including an annular brush ring having resilient bristles that project generally inwardly toward one another and terminate in free ends that cooperate to define a loose parts receiving and gripping hole.    
     
     
         2 . A concrete forming panel as set forth in  claim 1 , 
 said retaining structure further including a wall supporting said brush ring and having a clearance opening aligned with said hole for avoiding interference with a loose part received and gripped within the hole.    
     
     
         3 . A concrete forming panel as set forth in  claim 2 , 
 said brush ring being mounted beside said opening.    
     
     
         4 . A concrete forming panel as set forth in  claim 3 , 
 said wall having a marginal portion circumscribing said opening,    said brush ring including an annular base supporting said bristles,    said base of the brush ring abutting said marginal portion of the wall.    
     
     
         5 . A concrete forming panel as set forth in  claim 4 , 
 said wall having a retaining track for said brush ring,    said brush ring being retained on said wall by being wedged within said track.    
     
     
         6 . A concrete forming panel as set forth in  claim 5 , 
 said wall and said track comprising parts of an extruded member.    
     
     
         7 . A concrete forming panel as set forth in  claim 1 , 
 further comprising a frame including at least one stiffening member on said back side of the face sheet to rigidify the face sheet,    said brush ring being mounted on said stiffening member.    
     
     
         8 . A concrete forming panel as set forth in  claim 7 , 
 said frame including a pair of opposite side rails at the perimeter of the face sheet,    said stiffening member extending horizontally between and interconnecting said side rails.    
     
     
         9 . A concrete forming panel as set forth in  claim 8 , 
 further comprising a second horizontal stiffening member spaced vertically from the first-mentioned horizontal stiffening member and extending between and interconnecting said side rails,    further comprising a vertical stiffening member extending between and interconnecting said first-mentioned horizontal stiffening member and said second horizontal stiffening member.    
     
     
         10 . A concrete forming panel as set forth in  claim 7 , 
 said stiffening member extending vertically on said back side of the face sheet.    
     
     
         11 . A concrete forming panel as set forth in  claim 1 , 
 said retaining structure including a member that is generally T-shaped in cross-section, presenting a wall and a cross-head that intersects said wall at right angles thereto along one extremity thereof and projects in opposite directions therefrom,    said brush ring being mounted on said wall.    
     
     
         12 . A concrete forming panel as set forth in  claim 11 , 
 said wall being affixed along an opposite extremity thereof to said back side of the face sheet and extending generally edgewise outwardly therefrom.    
     
     
         13 . A concrete forming panel as set forth in  claim 11 , 
 said cross-head being affixed to said back side of the face sheet,    said wall projecting outwardly from the cross-head.    
     
     
         14 . A concrete forming panel as set forth in  claim 2 , 
 said wall having a pair of opposite sides,    further comprising a pair of axially aligned brush rings supported on opposite sides of said wall.    
     
     
         15 . A concrete forming panel as set forth in  claim 14 , 
 said wall having a pair of retaining tracks, one on each side of the wall,    each of said retaining tracks retaining a brush ring beside the opening.
