Ceiling Fixings
SOIL VENT PIPE ETC
The
Ceiling
clip
is
specifically designed to be
fixed after beam & block
flooring systems have been
laid. The Clip is economical
and its knock in design
gives fix after flexibility. It
allows adjustment for batten
size and position and avoids
dust, noise and cost of
drilling.

8. Protection
The beam and block floors as laid can, with due care,
safely cater for normal foot traffic. The MC shall provide
protection under barrow runs and at work positions for
following trades.
2. Design
The floor beams are designed to comply with B.S.8110:
Part 1. Refer to data sheet PT
9. Working at Heights
When working at heights (i.e. upper floors and/or floors
over basements), fall protection must be provided during
the installation of Beam & Block floors.
3. Infill Blocks
The density of the infill blocks used should not exceed the
value shown on the Milbank drawings. Infill blocks must
be capable of supporting a line load of 3.5kN on a span of
420mm. Standard block dimensions 440mm x 215mm x
100mm. Special format blocks/infill may be used in
accordance
with
the
block
manufacturers
recommendations.
4. Camber
All beams are prestressed and have an upward camber.
The degree of the camber is dependent on the span;
levelling screeds may be required prior to laying floating
finished.
5. Loading
The loadings for which the floors are designed are shown
on the Milbank drawings. The Main Contractor (MC) shall
ensure that these design loads are not exceeded during
construction.
6. Dimensions
The beams are manufactured in 50mm increments to the
lengths shown on the drawings. The MC shall check and
approve all the setting out dimensions shown on the
drawings and return a copy of the drawing signed as
approved, before manufacture can commence.
7. Installation
Access and hard standing shall be provided by the MC for
a mobile crane and transport as stated in the Milbank
quotation. The MC shall re-route and/or remove and
reinstate any overhead obstructions that may hinder the
installation of the flooring units. All bearing surfaces must
be constructed to the correct levels, be true and mature at
the time of installing the floor units.
10. Ground floors
The builder shall supply and bed all D.P.Cs under the floor
bearings, before the flooring units are fixed. The under
floor voids should be ventilated to comply with the building
regulations and the N.H.B.C. requirements.
All vegetable soil must be removed from under the floor
and the top surface of the oversite treated with weed killer.
11. Garage floors
Garage floors are designed for an imposed load of
2.5kN/m2 or a point load of 9.0kN. A minimum finish of
50mm thick screed 1:4 cement sharp sand, reinforced with
A98 fabric, is required.
12. Stacking
The slabs must be stacked the right way up, with timber
bearers, (provided by the client) placed just in from the
ends, vertically above one another. Similar length units
should be stacked together.
