Embodiment Construction

[0022] Such as figure 1 As shown, a ferrule locating tool, generally designated 10 , includes a base 12 and a locating element 14 . The tool 10 of this embodiment includes a magnetic element 16 disposed within the lower surface of the base body 12 and a pair of other magnetic elements 18A and 18B disposed within the upper surface of the base body 12 .

[0023] In this embodiment, the base body 12 is disc-shaped with a tapered peripheral wall 20 . The positioning elements 14 are in the form of pins or dowels which are threaded coaxially with the disc-shaped base 12 via fasteners (not shown). The diameter of the dowel 14 is such that it slidably receives an iron ferrule (not shown). It should be understood, however, that the dowel 14 may be replaced depending on the particular ferrule with which it is to be engaged. The dowel 14 may include a ring or circular magnet (not shown) in the vicinity of its threaded connection to the base 12 . This helps to magnetically secure the ...

Abstract

The invention relates to an iron hoop positioning tool (10), which comprises a base body (12) and a positioning element (14). The tool (10) includes a magnetic element (16) disposed within the lower surface of the base (12) and a pair of other magnetic elements (18A and 18B) disposed within the upper surface of the base (12). The positioning element (14) is in the form of a pin or dowel, which is threaded coaxially with the disc-shaped base (12) via fasteners. The iron hoop positioning tool (10) is designed to slide on the dowel (14) of the tool (10) as the iron hoop of the inclined plate. The lower magnet (16) of the tool (10) acts to temporarily fix the tool (10) to the formwork while the inclined slab is being poured into concrete.

Description

technical field [0001] The present invention generally relates to a hoop positioning tool such as for positioning hoops in precast concrete slabs or tilt panels. Background technique [0002] Sloping slabs are generally prefabricated into reinforced concrete using steel formwork. Inclined slabs consist of hoop gratings cast within the slab to provide anchor points at which to lift, support or secure the slab. Traditionally, iron hoops are individually bolted to the formwork at their predetermined locations. The slabs are cast in the formwork structure together with hoops and reinforcing bars, while bolts hold the hoops in place. When the concrete has set and the slab is free from the formwork, the bolts are removed. This technique for locating hoops suffers from at least the following disadvantages: [0003] (i) For each hoop, the steel formwork needs to be drilled, which is time consuming and labor intensive; [0004] (ii) Each panel has its ow...
