US 2007/0163395 A1 · MULTIPURPOSE CONCRETE TOOL

Abstract

A multipurpose concrete form tool (10) is provided which is designed to facilitate assembly and disassembly of concrete forms made up of side-by-side form panels (40). The tool (10) includes a primary handle (12), an upper hammer head (14) having a striking section (22) and a rearward claw section (24), and a lower, transversely oriented auxiliary handle (16). The striking section (22) presents a substantially flat striking surface (28) as well as rearwardly extending, top and lateral surfaces (30, 32, 34), which are also substantially flat and perpendicular to the surface (28). The claw section (24) is preferably of unitary, imperforate construction, presenting a rearmost solid claw surface (36). The tool (10) facilitates attachment and detachment of form panel-connecting wedge pins (50, 52), manipulation of individual form sections (40), and removal of residual concrete (54).

Dependent claims

A multipurpose concrete tool comprising:

an elongated primary handle presenting a longitudinal axis;
a hammer head adjacent one end of said primary handle and including a forward striking section and a rearward claw section,
said forward striking section presenting a substantially flat striking surface, a top surface, and a pair of lateral surfaces extending rearwardly from said striking surface,
said top surface and at least one of said lateral surfaces being substantially flat and transverse relative to said striking surface,
said claw section presenting a rearmost, unitary and imperforate claw surface;
and
an elongated auxiliary handle secured to said primary handle in spaced relationship to said hammer head and transversely oriented relative to the longitudinal axis of said primary handle.

A method of detaching concrete form panels from a completed concrete body, wherein the form panels have slotted connection flanges with tapered form wedge pins extending through adjacent flange slots to interconnect adjacent form panels, said concrete form detachment method comprising the steps of:

(a) providing a tool having a primary handle and a head at one end of the primary handle that presents a forward striking section and a rearward claw section;
(b) detaching the wedge pins by striking the tapered ends of the wedge pins with the striking section of the tool;
(c) using the tool to remove the concrete forms from the completed concrete body, step (c) including the steps of inserting the claw section of the tool into one of the flange slots of one of the form panels, and pulling the form panel away from the completed concrete body;
and
(d) removing residual concrete from the form panel with the claw section.
