发明名称 Construction form plug for nail
摘要 A low cost, durable, easily reuseable construction form plug (10) is provided to secure a nailed board (42) to the top of a construction form (38). The form plug (10) preferably includes a body (12) presenting a plug end (16), a flange (18) and a bore (30). The plug end (16) is inserted into a hole (35) within the construction form (38), a nail (40) is then driven through the bore (30) so as to engage the board (42) so that the board (42) is securely fixed to the form (38) thereby raising the effective height of the form (38) for purposes of pouring concrete (46) and the like. The plug end (16) includes a circumferential rib (20) which extends radially slightly beyond the radial periphery of the plug end (16) proper. In particularly preferred forms, the form plug (10) is composed substantially of 20% high density and 80% low density polyethylene.
