Dead load & live load for PU Panels

[tjk2007]

Dear all,

could anybody help me regarding this?

I have to submit the following details to my consultant regarding construction of cold rooms with PU panels:


Dead Load
Live load
shear stress
deflection due to bending.
The cold room is constructed with the following details:


Internal Dimensions: 4.89x1.49x2.45 m (LxwxHt)
Wall & Roof Panels :100 mm thk PU panels with 0.7 mm PVC plastisol cladding
Floor Panel :62 mm PU floor insulation including 50 mm thk PU panel ,12mm thk WBP plywood & 2mm thk SS chequerd plate.
Room temperature : 4 deg C
Foam density : 40 kg/m3
I have to prove to the consultant that the permissible load for the floor panel is 4000N/rubber wheel at a surface of >4 cm2

Kindly support me to prove.

Advice me with your valuable statements & some useful links also.

Thanks & Regards

Only the manufacturer of the panels can give you those via tests they've done unless it's a concrete floor.

i wouldnt be using wood especially that thickness for a floor

[Peter_1]

All the upper layer of the panels we use for floors is made of wood (panels with phenol glassfiber layer)
How otherwise you could spread the load to the PU when entering with a reachtruck.
Pointload of those we use (Isocab , Thyssen Krupp or Isobar) is 200kg/wheel (pointload) or 800 kg on 4 rubber wheels for a reinforced floor (= 15 mm wood)

concrete type 15 mm sheeting has balls compared to wood that can break down with contnual exposure to moisture and can be covered in tin etc if job permits for ease of cleaning etc

With such a small cold room, I wonder how the MHE can go in with 4 wheels. We use 125mm Thk floor panels with 12mm Ply wood & Chq Steel ( ss 304) for hand pallet truck movement & have seen no problems whatsoever even at -40 deg C
