How about the fire performance of reinforced concrete floor slabs

The fire performance is relatively good, and the reinforced concrete floor slab will not burn, but if other items in the room are burned, the high temperature of the flame will burn the concrete, and then the steel bars inside will be melted, causing the collapse of the entire floor slab.

Cast-in-place monolithic beam slab, thickness of protective layer.

1cm, plate thickness 10cm, fire resistance limit 2 hours, non-combustible body.

Cast-in-place integral beam plate, the thickness of the protective layer is 1cm, the thickness of the plate is 10cm, the fire resistance limit is 2 hours, and the body is not combustible.

Cast-in-place integral beam plate, the thickness of the protective layer is 1cm, the thickness of the plate is 12cm, the fire resistance limit is small, and the body is not combustible.

Simply supported reinforced concrete floor slab, protective layer thickness 1cm, fire resistance limit 1 hour, non-combustible body.

Four-sided simply supported reinforced concrete floor slab, the thickness of the protective layer is 1cm, the thickness of the plate is 7cm, the fire resistance limit is small, and the body is not combustible.

Overall not very good.

Summary. Dear, you can find out that the reinforced concrete floor slab is not allowed to burn fire.

Dear, do not burn directly on the concrete floor, the concrete floor will become brittle when exposed to high temperature for a long time, which will seriously affect the durability of concrete, and the damage to nuclear hail concrete is also great. If it must be burned, it is recommended to build a simple stove or stove on the concrete floor, and the distance between the open flame and the ground should be 20 to 30 cm less than the state mold.

Pro, the spring slip search steel bar jujube wax cement buildings are generally made of reinforced concrete, which is not easy to burn, but because of the accumulation of a large number of items inside, including flammable and explosive materials, this leads to the fact that although there is only a little spark, it can make the whole building burn. Reinforced concrete (English: reinforced concrete or ferroconcrete) is often referred to as reinforced concrete (tong) in engineering.

It refers to a composite material composed of steel reinforcement, steel plate or fiber in concrete to improve the mechanical properties of concrete. It is one of the most common forms of stiffened concrete.

Summary. Hello dear, the advantages of cast-in-place reinforced concrete floor slabs: the overall performance and stiffness of the structure are good, suitable for seismic fortification and buildings with high integrity requirements, rooms with pipes passing through the floor slabs (such as kitchens, bathrooms, etc.), rooms with irregular shapes or room scales that do not meet the requirements of modulus.

Cast-in-place reinforced concrete floor slab refers to the floor slab made by formwork, binding steel bars, pouring concrete, curing and dismantling formwork according to the design position on site. The floor slab is strong, durable, fire-resistant, and cost-effective.

The cast-in-place reinforced concrete floor slab is a floor slab structure formed by formwork, binding steel bars, and pouring concrete at the construction site according to the design position. Reinforced concrete structures refer to structures made of concrete reinforced with steel bars. The main load-bearing elements are built with reinforced concrete.

It includes thin shell structures, cast-in-situ structures of large formwork, and reinforced concrete structures constructed using sliding formwork, rising plates, etc.

The role of fireproof steel bars of the floor bearing plate can form a fire-resistant thermal insulation protective layer to improve the fire resistance limit of the steel structure, which is divided into thick, thin, ultra-thin and so on. The thick coating is granular, the thickness of the coating is usually more than 8 mm, the construction method is spraying, and the thickness of the coating itself and the low thermal conductivity are relied on at high temperature to insulate the steel components for socks. Thin and ultra-thin coating is thinner, has a certain decorative effect, the construction method can be sprayed or brushed, and the coating expands and thickens to protect steel components at high temperatures.

It has light weight and simple construction, and is suitable for concealed structures and steel beams, diagonal braces and other steel components.

Cast-in-place floor slabs do not have to be made of seismic reinforcement.

Because of the steel bar, the fire resistance is generally not good.

The fire performance of reinforced concrete floor slabs is level 1, what do you want to ask!
