ADVANTAGES OF EARLY STRIKING

The Technique of Early Striking
Early striking is a technique whereby the formwork is removed three to four days after pouring a slab, but the supporting structure of scaffolding or props remains undisturbed until the concrete is strong enough to support its own weight over its full span. Concrete generally takes 28 days to attain its full constructional design strength. Most engineers will only permit the complete support to be removed after about 10 to 14 days, depending on the ambient temperature and cube strength tests.With today’s high costs of formwork it is important to use it as frequently as possible. Traditional formwork locked in situation for 10 to 14 days with a pouring cycle in excess of this is outmoded by the F-Lock early striking system and its facility to speed the cycle of operations. This practice has been widely accepted especially as the rising costs of materials and labour have proved that the early striking is safe efficient and cost-effective.How it is set
A complete set of F-Lock Decking and support is used for the first floor slab. After three to four days of pouring the concrete, the infills and decking beams may be struck for re-use on the second floor slab while support remains in place during the rest of the curing period. In practice, it is found that support around columns. close to walls and beams can be removed. About 1/3 of these are free for re-use. Additionally, about 2/3 of support will be required for the second floor. After pouring the second floor, the formwork may be removed after three to four days.

 DECKING BEAMS

DECKING BEAMS

The light weight steel fabrication includes a 100mm wide top flange which eliminates the necessity for a plywood infill, so cutting down maintenance costs. Heavy duty pressings are fitted to the beam ends ensuring adequate protection against site abuse. These incorporate a tongue location for the drophead.

 INFILL BEAMS

INFILL BEAMS

The infill beams have been designed to be used with the Decking Beams to provide a support for plywood decking.
The infill beams come in 5 lengths to allow for flexibility of grid sizes to suit all types of slabs .

 ADJUSTABLE BASEJACK

ADJUSTABLE BASEJACK

The adjustable Base Jack is used at the bottom of the Standard to provide an additional maximum adjustment of 400 mm.

 UNIVERSAL JACK

UNIVERSAL JACK

The 57KN capacity galvanized Universal Screw Jack has an adjustment range of over 400 mm. It is manufactured from 38 mm outside diameter steel tube with a rolled square thread for fast trouble free operation. The Jack can be used either at the top or the bottom of the vertical standard. In each case the unthreaded portion is inserted into the Vertical so that the correct amount of the Jack always remains inside the Vertical for safety.

 DROPHEAD

DROPHEAD

Falcon’s quick action dropheads, supplied with nuts and bolts, are designed to fit standard props or adaptors for F-lock scaffolding. They allow panels and beams to be struck and reused after only three or four days, leaving the support in position for the remainder of the curing period of the concrete slab. The primary head remains in contact with the concrete, while the secondary head and its supporting wedge are released by a single hammer blow. The height of the drophead is 214mm. The striking distance allows the beams and panels to drop only 115mm for their safe removal, a marked improvement in terms of speed and safety when compared with other systems. The dropheads have a load carrying capacity of 40KN.
