Lateral Restraints New Product

Lateral Restraints are manufactured from 304 Austenitic Stainless Steel rods, 8mm in diameter, designed to restrain the whole of the brick outer structure to the floor joists.

Lateral Restraints can be fitted from outside the property with a minimum of disturbance in most cases just a lifting of the floorboards to determine the position of the joists.

The process would normally be done by using angle straps screwed onto the joists. This has several drawbacks:

  • The disturbance caused to the householder is quite considerable.
  • The fixing to the joist is only as long as the shear strength of the screw heads.
  • If fitted furniture or bathroom suites is in situ, these have to be removed which would involve using specialist trades such as joiners and plumbers.

Supplied in 1 metre lengths.

Application
  • Drill a 14mm hole through both brick outer and inner leaf.

  • Push the long restraint into the pilot hole and attach the lateral restraint fixing key.

  • The lateral restraint is slowly wound through the joists leaving the outer end recessed approximately 15mm.

  • The outer end can now be tested for strength of fix (typically 5Kn - 10Kn)

  • The outer end of the lateral restraint is then resin bonded into the brick work and finished off with either mortar or mastic.

The same restraint is used to suit different situations, as shown below.

Timber Joist Repair

Any joist or beam end in direct contact with a wet wall will eventually succumb to fungal attack and decay (rot) thus loosing its strength, it may even break. Should this happen the problem of replacement is expensive and time consuming.

Bower Beams Joist End Repair Plates can be used to effect a quick, cheap and easy but secure and long lasting replacement.

Independent tests have shown that the Bower Beam Joist End Repair Plates are capable of withstanding loads in excess of the design loads of the wooden joists they are supporting which will in turn, be isolated from the source of the dampness and further risk.

All of these joist repair plates can be used as timber splicing plates by fastening an equal number of coach screws either side of the splice.

Bower Beams Joist End Repair Plates are supplied in pairs, available in 4 Sizes:

  • BM6 - (W) 100mm x (L) 600mm (Cut back to 6")

  • BM9 - (W) 100mm x (L) 700mm (Cut back to 9")

  • BM17 - (W) 100mm x (L) 1000mm (Cut back to 17")

  • BM17W - (W) 150mm x (L) 1000mm (Cut back to 17")

Coach Screws supplied with each pair.

Installation

1. Cut away the affected timber up to the required length from the joist end.

2. Offer up the two halves of the Bower Beam to the joist and slide forward into the socket. Secure with nails.

3. Drill the required number of pilot holes for the coach screws (not opposite each other).

4. Tighten down the coach screws. Note: a blocking piece will be necessary on large cut backs to fasten down the floor boards. Joist widths from 2 inches (50mm) up to 6 inches (150mm) can be replaced by this method. Normal treatment to dispel further fungal attack should be carried out.
