Willing fiber cement floor board is mainly used for the duplex structure of upper and lower bilayer in the loft building;The old building plus layer renovate the floor,changing the former monolayer to double layer space; Steel structure floor separation etc
Under normal circumstances,the distribution space of main girder is @2440mm, the section size of the steel beam can be calculated according to the span, the distribution of the secondary girder intersecting the main girder is @610mm,the distribution of the secondary girder paralleling to the main girder is @1220mm
*whenconstruction,size 40*40*3mm steel mesh can be laid under the fiber cement loft board,there must be 30-60mm thick cement mortar on the steel mesh, and then finally the loft board become the best decorative material for the building.
* Willing fiber cement loft board belongs to cement product,the abrasive resistance is not very good,so when finished the installation,the surface always need do other treatment such as sticking ceramic tiles,laying wood floors or carpets,brushing the paint
*If the loft board used for the old building plus layer renovating floor,it should consider the load bearing capacity of the original wall,and the steel plate must use the chemical anchor bolt to fix the main girder
