1, slab bottom reinforcement is a kind of reinforcement in buildings, which is mainly used to strengthen the bearing capacity of concrete slab bottom. Full-pressure and half-pressure are two different treatment methods for steel bars at the bottom of slab in construction.
2. Full reinforcement: It means that all the steel bars are compacted in the mid-span position of the steel bars at the bottom of the slab, so that they are closely attached to the bottom of the concrete slab and reach the maximum bearing capacity. The advantage of full reinforcement is strong bearing capacity, which can improve the strength and stability of concrete slab bottom.
3. Half-pressed reinforcement: it means that only half of the reinforcement is pressed at the mid-span position of the reinforcement at the bottom of the slab to make it fit the bottom of the concrete slab. The advantage of pressing half-bars is good elasticity, which can alleviate the influence of the stress at the bottom of the plate to a certain extent, save the amount of steel bars and reduce the cost.
4. The difference between full-pressure steel bars and half-pressure steel bars is that the density of steel bars is different. Full-pressure rebar compacts all rebar to make it closely fit with the bottom of concrete slab, while half-pressure rebar compacts only part of rebar, and the other part leaves a gap with the bottom of concrete slab. This treatment can alleviate the influence of the stress at the bottom of the slab to a certain extent, save the amount of steel bars and reduce the cost.
