I have three houses, the length is 7 meters, the width is 4 meters, I would like to use a 4 meter trough board to do the support, and then put concrete slabs on the channel, the two floor of the roof also do so, can I do that? If it is possible to use a large trough plate, a thick concrete slab, and a thick steel bar for concrete slabs Thank you
Channel steel, of course, when the beam, the best 3600*3600mm, plate thickness of 100mm, reinforced two-way double 8@200, grade three steel
Channel steel can be used as columns, but also a combination of channel steel and concrete as a pillar, the thickness of the board is best to take 120mm, double steel two-way 8@200, three steel enough
The concrete of channel steel is made of concrete and steel bar. This kind of floor has the advantages of firmness, durability, rigidity, high strength and good fire resistance, and is widely used at present. According to the construction method, it can be divided into two major categories: cast-in-place reinforced concrete floor and prefabricated reinforced concrete floor.
Channel steel plus concrete slabs can be used as floor slabs.
