Abstract
A control joint for forming and controlling concrete structures such as floors and tilt-up walls. The joint has a base and an upstanding web and is preferably extruded from plastic having a honeycomb cell structure. The honeycomb structure may include a metal reinforcing section extending within the structure along the length of the joint. The joint may be utilized to form various concrete structures such as sidewalks, pads and tilt-up walls.

A control joint for use in casting concrete sections on a supporting base, said control joint comprising:
- (a) a base;
- and
- (b) a web having opposite sides, said web tapering upwardly from said base to a top and integrally formed therewith, said base and web being formed as an integral extruded member defining a honeycomb structure with a single web associated with the base, the base extending oppositely from said web.
A control joint for use in casting concrete sections on a supporting base, said control joint comprising:
- (a) a base;
- (b) a web having opposite sides, said web extending upwardly from said base to a top and integrally formed therewith, said base and web being formed as an integral extruded member defining a honeycomb structure with a single web associated with the base;
- and
- (c) locking tabs oppositely extending from the sides of said web intermediate said base and top.
A control joint for use in casting concrete sections on a supporting base, said control joint comprising:
- (a) a base;
- (b) a web having opposite sides, said web extending upwardly from said base to a top and integrally formed therewith, said base and web being formed as an integral extruded member defining a honeycomb structure with a single web associated with the base;
- and
- (c) a projection depending downwardly from the base generally aligned with the web, said leveling projection being engageable in a concrete pad.
A control joint for use in casting concrete sections on a supporting base, said control joint comprising:
- (a) a base;
- (b) a web having opposite sides, said web extending upwardly from said base to a top and integrally formed therewith, said base and web being formed as an integral extruded member defining a honeycomb structure;
- and
- (c) said web defining a plurality of spaced-apart slots extending from said top spaced and sized to receive and support wire mesh reinforcing.
A control joint for use in casting concrete sections on a supporting base, said control joint comprising:
- (a) a base;
- (b) a web having opposite sides, said web extending upwardly from said base to a top and integrally formed therewith, said base and web being formed as an integral extruded member defining a honeycomb structure;
- and
- (c) reinforcing members located within said honeycomb structure.
A control joint for use in casting concrete sections on a supporting base, said control joint comprising:
- (a) a plurality of control joint sections each having:
- i. a base;
- ii. a web having opposite sides, said web extending upwardly from said base to a top and integrally formed therewith, said base and web being formed as an integral extruded member defining a honeycomb structure;
- and
- (b) clip means defining openings to receive the base and web of adjacent sections to secure them together.
