초록 ▼

A panel unit used as part of a form for a concrete wall has a pair panels, held in spaced apart relation by a spacer. A spacer has rods with angled rod portions at the end which co-operate with other rod members to form retention cells which can receive reinforcement bar members. Another spacer is pre-fabricated in a generally planar grid with reinforcement members secured thereto. Connectors are used to connect the spacers to the panels. One type of connector is formed in two parts, with one part being removable, to permit removal of the panel, the other part having an anchoring mechanism. Another connector has a blade element enabling the connector flange to be recessed in the outer surface of the panel. A corner panel unit is also provided, as is a panel unit adapted for forming a wall with a ledge. In other panel units, form liners are provided which can permit a textured or contoured finished wall surface to be produced.

I claim: 1. A panel unit for use as part of a concrete form, said panel unit comprising:(i) first and second spaced apart longitudinally oriented foam plastic panel members defining a form space there between;(ii) a spacer comprising at least one transverse tie rod member secured to and extending between said first and second panels, said transverse tie rod member having a first end adapted to be secured to a first connector for connecting said transverse tie rod member to said first panel member;wherein said first connector comprises a connector assembly for use in securing said first panel member to a transverse tie member, said connector assembly comprising:(a) a cap member having a flange cap portion and a shaft portion, said shaft portion with an end having an opening adapted to be interconnected to an end portion of a tie member; and(b) a bushing member having a flange portion and an axially aligned shaft portion with an end opposite to said flange portion, said bushing member having a continuous cavity formed in and passing through said flange portion and said shaft portion;said shaft portion of said cap member being receivable axially into said continuous cavity of said bushing member through said flange portion toward said end of said shaft portion for releasable engagement with said end of said tie member extending through said end of said bushing member into said continuous cavity; andsaid flange portion of said bushing having at least one aperture passing there through, said aperture and having an opening for permitting the fluid communication of flowable concrete into said aperture, said aperture being configured such that when concrete flows into and hardens in said aperture, said hardened concrete in said aperture of said bushing member which is integrally connected to hardened concrete outside of said aperture of said bushing member provides an anchoring device to hold said bushing member in said hardened concrete.
