How to install Plastic PVC slab beam formwork ?

Tip 01: Edge distance of nailing/screwing 

To prolong the life-span of product, we suggest to leave at least 3-5cm distance from the edge when nailing/screwing on it. 

Tip 02: Beam distance 

In general, we suggest the same beam distances as the plywood formworks which you are using. But, it differs a bit according to the frame structures and concrete thickness. The stronger structures, the shorter beam distance.

Tip 03: Nailing/screwing distance 

Same as the general requirements for all formwork materials, to ensure the average load-bearing capacity of the entire sheet, in addition to the appropriate props distance, we also recommend maintaining an average spacing of nails/screws, such as 30 cm. Especially the corners should be fixed well with nails/screws. Or you can keep the regular way that applied to your structures. 

Tip 04: Joint treatment

If you want to avoid the concrete sticking into the joint, you can paint the joint. The regular painting is workable enough. Some of our clients use the gel coat.

Tip 05:  Repair the holes of nails or bolts 

For the nails holes: normally such holes don’t leak concrete, so not necessary to fix it. If you have strict requirements, you can use glue or wax to cover them. 

For the bolt holes: plastic plug or adhesive tape. Another solution: normally the bolt holes of one single project have same diameters and locations. So some clients cut formworks sheets into small round pieces with 1mm smaller diameter, and then insert them into the bolt holes.
