Application technique

For four-sided column casings Promatect 250 soldiers are wedged between the flanges

at the top and bottom of the column.

The soldiers are 120mm wide x casing thickness. The boards are fixed to the soldiers

and to each other using steel staples, 50mm long x 12.5mm wide x 1.6mm thick, at

150mm centres.

The end staples are located nominally 40mm from the corner of the board. Soldiers maybe fitted behind board joints as an option. Cover strips are not required over joints in the

boards covering the flanges. Board to board joints on adjacent sides are staggered by at

least 530mm.

For single layer boards 12 or 15mm thick the length of the staples may be reduced to

35mm.

For three-sided beam casings the fixing method is the same except that the soldiers arerequired to be fitted at the ends of the beam and at maximum 1250mm centres and the

soffit board is fitted between the side boards. Soldiers must coincide with board joints.

For double-layer casings, the first layer is the thicker of the two layers and is fixed as a

single layer casing. The outer layer is then secured through the first layer into the

soldiers and to each other using staples, 50mm long, at 150mm centres. Board joints are

staggered between layers by at least 530mm.

On steel sections up to 400mm deep, the soldiers may be cut in half, with the cut

sloping by 5mm from side to side, and the two parts tapped together to wedge the

soldier in position. For steel sections deeper than 400mm and up to 686mm deep, each

soldier is strengthened using a Promatect 250 stiffener to form a T-shaped soldier. Thestiffener is the same thickness as the standard soldier and is wedged between the

flanges. The standard soldier is stapled to the outer edge of the stiffener to form the T-

shaped soldier.

For steel sections deeper than 686mm and up to 1.0m deep, each soldier is strengthened

using a Promatect 250 stiffener to form a T-shaped soldier. The stiffener is glued and

stapled to the soldier using Vicubond adhesive. The stiffener is the same thickness asthe standard soldier.

Promatect 250

ACC/PJ1-FM D08

The T-shaped soldiers are glued in position in the steel section using Vicubond adhesive

and the Promatect 250 facing boards stapled to the T-shaped soldiers, as per the

standard fixing recommendations.

Alternatively, for steel sections up to 1.2m deep, the framed casing arrangement may be

used, as detailed below.

The application technique for four-sided beam casings is the same as for three-sided

beam casings with the addition of the board protection on top of the beam, fitted

between the side boards.

Promatect 250 board

As an alternative to using Promatect 250 soldiers, for steel sections up to 686mm deep,

the side boards may be secured using continuous galvanised steel angles, 32mm x

18mm x 0.8mm thick, or equivalent. The angles are fastened to the steel beam or

column with minimum M4 steel screws at 500mm maximum centres. The boards are

fastened to the angles with steel drywall screws at 200mm nominal centres.

Board to board side panel joints are backed with Promatect 250 cover strips, 120mm

wide x 15mm thick, fastened with staples.

3 and 4-sided framed casing to deep web beams greater than 686mm deep

The construction of the framed casings for deep web beams greater than 686mm deep is

shown in Figure 1.

Framing:

32mm x 52mm x 32mm x 0.5mm steel channel fixed to the underside of the top flanges

and the upper side of the bottom flanges of the steel beam. Vertical steel channels,

32mm x 52mm x 32mm x 0.5mm, are fitted into the horizontal channels at 1250mmcentres.

Fixings:

Channel to flange: shot fired 3.7mm x 16mm steel nails (Hilti ENK 16 S12 or

equivalent) or selftapping 9.5mm x No.8 panhead screws at 500mm maximum centres.

Board to channels: No. 8 countersunk self-tapping hardened steel or dry wall screws atnominal

200mm centres. Screw length should allow minimum of 10mm penetration through the

channel.

Board to channels: No. 8 countersunk self-tapping hardened steel or dry wall screws at

nominal 200mm centres. Screw length should allow minimum of 10mm penetration

through the channel.

Board to board: steel staples, 50mm long x 12.5mm wide x 1.6mm thick, at 150mm

centres.

The end staples are located nominally 40mm from the corner of the board. Board to

board joints on adjacent sides are staggered by at least 530mm. For single layer boards

12 or 15mm thick the length of the staples may be reduced to 35mm.

Cover strips:

Promatect 250 internal cover strips, 100mm wide x minimum thickness of the side

panels, at the position of vertical board joints in the Promatect 250 side panels. The side

panels are fastened to the cover strips, on both sides of the joint, with steel staples,

50mm long x 12.5mm wide x 1.6mm thick, at 150mm centres. The soffit panels are

fitted between the side panels and fastened with steel staples, 50mm long x 12.5mm

wide x 1.6mm thick, at 150mm centres. For single layer boards 12 or 15mm thick thelength of the staples may be reduced to 35mm.

Through Penetrations:

All through penetration gaps shall be treated as per the approved independent

firestopping designs
