Steel frame showing the 8in diameter holes in the universal beams and the temporary wire bracing ropes
without expensive welded infilling
of castellation being necessary.
Sufficient brickwork panels
were included in the design to
ensure lateral stability for each
building. The concrete floors
serving as horizontal diaphragms
to bring wind forces to the stiff
panels.
In the erection stage of the
steel frame, temporary restraint
was provided in the form of ½in
diameter steel ropes connected
with bulldog clips to steel yokes
clamped to the beam or column
members. These remained in
position whilst floor units were
erected and were finally removed
as the wall panels were built.
The steel framed sports block,
with the gymnasia at first floor
level and with the changing
accommodation under, has the
100ft × 60ft sports hall spanned
by portal frames at 20ft centres.
Latticed roof trusses to the
swimming pool and gymnasia are
in RHS and CHS members shop
welded complete.
The present development,
with allowance for foundation
abnormals, has been carried out
within the current Department
of Education and Science cost
limits. This client has benefited
from building areas greater than
the minimum laid down and from
the special provisions within the
sports block. This may be due in
no small measure to the economic
and efficient contribution of the
steel-concrete design.
The first school was occupied
22 months after commencement,
the second school 24 months,
with overall completion, other than
planting and playing fields in 27
months.
