PASCHAL-WERK G Maier, a leading European formwork specialist, has made the forming and dismantling of formwork for lift shafts easy with the recent introduction of the dismantling inside corner post for its Logo.3 formwork system.

A practical addition to the Logo.3 system, the movable dismantling inside corner post greatly reduces the time required to form and dismantle the inner formwork when constructing lift shafts, stairway cores and structures with tight spaces, says Amir Delghandi, director general of Bahrain-based Paschal Concrete Forms, the regional office of the German formwork manufacturer.

This addition received an “enthusiastic” response at the bauma construction equipment exhibition in Germany, where it was unveiled last year, he says. Now, almost all trade partners have integrated the Logo.3 dismantling inside corner post in their range and many customers have purchased it to expand their formwork materials, as the dismantling inside corner post is also compatible with the Logo alu formwork system, he points out.

Elaborating on the latest addition to the Logo.3 system, Delghandi says: “Each dismantling inside corner post has a hexagon nut on the top of the inside corner post in order to open or close the side parts – using either an SW36 spanner or a DW15 tie rod which fits in the drill hole of the hexagon nut.

“The lengths of the dismantling inside corner posts are adapted to the height of the Logo.3 formwork system elements from 75 cm to 340 cm. If larger formwork heights are required, the dismantling inside corner posts can also be connected together at their joints. A bolt is inserted into the hexagon screw head of the lower dismantling inside corner post. This allows the whole corner to be opened or closed from the top element.

“Particular attention was given to ensuring that the dismantling inside corner posts can be easily pushed together or can be put in position without the inner formwork having to be disassembled.

“The individual dismantling inside corner post elements are joined together with the wedge clamp or multi-clamp at the joints, exactly like the formwork elements.”

According to Delghandi, the benefits of Paschal’s dismantling inside corner post can particularly be seen when dismantling the formwork. They can be adjusted by approximately 50 mm on each side. When retracting the corner posts, the entire inner formwork frame can be loosened and moved at a stroke, thus eliminating the need to disassemble the inner formwork. After retracting the corner posts, the complete inner formwork can be lifted out with a crane and reused.

Modular range

Meanwhile, Paschal has expanded its universal Modular formwork system even further with the addition of its variable “Modular column formwork”, thus boosting its unbeatable cost-benefit ratio.

The move comes in response to the demands of various export countries where reinforced concrete frame construction is dominant.

“This system expansion allows you to form square as well as rectangular reinforced concrete columns with external dimensions ranging from 20 to 50 cm in increments of 5 cm,” says Delghandi.

The system is designed to build column forms in varying lengths, widths and heights in a short time using a small number of light panels.

“If special requirements are additionally placed on the column edges, chamfer angles or sealing strips can be inserted in the corners of the formwork and fixed there,” he says.

The panels come in heights of 100 cm, 125 cm and 150 cm and have a fixed width of 60 cm. The modular column panel, measuring 60 by 150 cm, has a dead weight of less than 40 kg, so it can be easily handled by two people.

The height of the Modular column panels can be extended by fastening them one below the other using the keybolts. Connection holes have already been made in the frame profiles and plywood to provide a force-fit corner connection with locking screws.

The 15-mm-thick phenolic resin-coated plywood comes with holes which are sealed at the factory with PVC (polyvinyl chloride) plugs, which simply have to be popped out on the construction site. The locking screw fits through the two parallel opposing holes so that it can be hammered in from the outside as usual, says Delghandi.

The Modular column formwork system is configured for a maximum fresh concrete pressure of 60 kN per sq m in accordance with Din 18218.

Paschal offers supports and adjustable props with suitable connecting and fastening accessories for aligning the formwork units.

Headquartered in Germany, with customers in more than 40 countries and 50 years of experience, Paschal entered the Middle East market in the early 1970s. Due to the rise in demand for formwork in the region, it set up its regional office Paschal Concrete Forms in 1997. To enhance its service to clients even further, Paschal built its own 3,200-sq-m covered facility in Salman Industrial City (BIIP) at Hidd in Bahrain in 2010.
