Abstract

A cantilevered apparatus for positioning anchor bolts (or reinforcing steel) in formwork comprises a main body having a longitudinal slot for receiving slidable bolt holders, with the main body being longitudinally slidable relative to, but vertically, horizontally, and rotationally constrained by, a single mounting bracket rigidly mountable to the formwork, such that the portion of the main body carrying bolt holders can cantilever from the mounting bracket to extend over the formwork. After the mounting bracket has been positioned on and fastened to the formwork, the bolt holders may be laterally positioned relative to the formwork, and the bolt holders may be fastened to the main body, thus holding the bolts (or reinforcing steel) in position relative to the formwork. In variant embodiments, the mounting bracket may be configured to enable angular adjustment and/or height adjustment of the main body and/or relative to the formwork.

Dependent claims

An apparatus for positioning anchor bolts, steel reinforcing bars, or other elongate articles in formwork defining a cavity for receiving fluid concrete for a concrete structure, said apparatus comprising:

(a) an elongate main body having a first end and a second end, and comprising two side members defining a longitudinal slot for receiving one or more bolt holders longitudinally movable therewithin;
and
(b) a single mounting bracket comprising:
(b.1) a lower section rigidly mountable to the formwork;
and
(b.2) an upper section connected to the lower section and configured for engagement with the main body such that the main body will be longitudinally movable relative to the single mounting bracket, while also being constrained by the upper section against longitudinal or lateral rotation and vertical movement relative to the upper section;
wherein:
(c) when the lower section of the mounting bracket is mounted to the formwork, with the main body longitudinally movably engaging the upper section of the mounting bracket:
(c.1) the longitudinal position of the main body relative to the mounting bracket and the formwork will be adjustable to cantilever a selected portion of the length of the main body from the mounting bracket, to extend over the formwork cavity;
and
(c.2) the longitudinal position, relative to the main body, of any movable bolt holder disposed in the longitudinal slot of the main body will be adjustable by longitudinally moving said bolt holder longitudinally relative to the main body;
and
(d) the connection between the upper and lower sections of the mounting bracket is designed to transfer, from the upper section to the lower section, reaction forces and bending moments induced in the upper section by the weight of the cantilevering main body and any bolt holders, bolts, steel reinforcing bars, or other elongate articles carried thereby.

and
(b) a single mounting bracket comprising:
(b.1) a lower section rigidly mountable to the formwork;
and
(b.2) an upper section connected to the lower section;
wherein:
(c) the first end of the main body is fixed to or integral with the mounting bracket;
(d) when the lower section of the mounting bracket is mounted to the formwork:
(d.1) the main body will be cantilevered from the mounting bracket to extend over the formwork cavity;
and
(d.2) the longitudinal position, relative to the main body, of any movable bolt holder disposed in the longitudinal slot of the main body will be adjustable by longitudinally moving said bolt holder longitudinally relative to the main body;
and
(e) the connection between the upper and lower sections of the mounting bracket is designed to transfer, from the upper section to the lower section, reaction forces and bending moments induced in the upper section by the weight of the cantilevering main body and any bolt holders, bolts, steel reinforcing bars, or other elongate articles carried thereby.
