What are the main structures of the floor layer?

The floor layer is generally composed of several basic layers such as the surface layer and the roof of the structural layer.

1. The surface layer mainly plays a role in ensuring the use of the room and protecting the structural layer, and also plays an important decorative role in the indoor environment.

2. The structural layer is the horizontal load-bearing component of the building, mainly including plates, beams, etc., and the structural layer bears all the loads of the entire floor layer, and plays the role of dividing the internal space of the building and fire prevention and sound insulation. The floor slab should have sufficient strength, stiffness, and fire resistance.

3. The main function of the ceiling is to meet the needs of interior decoration, improving the proportion of space, installing lamps and lanterns, and arranging pipelines.

4. The additional layer is usually arranged between the surface layer and the structural layer, mainly including sound insulation board, waterproof layer, thermal insulation or heat insulation layer, etc.

The floor layer is mainly composed of a surface layer, a structural layer, an additional layer, and a roof.

1) Surface layer. The surface layer is the contact surface where people, furniture, machines, etc. stand or are placed. Its main role is to protect the floor slab, interior decoration and facilitate cleaning.

Roof: It is the load-bearing and enclosure component of the top of the building, which is generally composed of three parts: roof, thermal insulation (insulation) layer and load-bearing structure.

Floor stratum: It is a horizontal load-bearing component in a building, including the ground floor and the floor layer in the middle.

1. The floor slab must have sufficient strength and stiffness.

The strength of a floor slab refers to its ability to withstand its own weight and use loads without breaking to ensure safety. The stiffness of the floor slab means that the deformation (deflection) does not exceed the specified amount under the load.

2. The floor layer should meet the requirements of fire prevention, sound insulation, heat preservation, heat insulation, etc.

Due to the different locations of the floor layers, some require sound insulation, while others require thermal insulation or heat insulation, but all floor slabs have fire protection requirements.

Floor layer sound insulation, which is to block solid sound. Structural insulation solid sound transmission needs to start from attenuating impact energy, such as adding elastic materials to the floor floor, floating floor slabs and hanging ceilings. The bulk density of the floor slab is generally large, and the areal density is inevitably large, which has a certain blocking ability for air sound.

Therefore, the sound insulation of the floor slab is mainly to isolate the solid sound.

For fire prevention and safety, floor slabs should generally be made of non-combustible materials. At present, most of the widely used reinforced concrete floor slabs can meet the fire protection requirements. The fire code stipulates that the floor slab of a Class IV fire-resistant building may be refractory to combustible, and its fire resistance limit shall not be less than h (hours); The floor slab is not allowed to use combustion.

The floor layer is generally composed of several basic layers such as the surface layer, the structural layer, and the roof layer.

The floor layer requires sufficient strength and rigidity, and it also has certain functions such as sound insulation and fire prevention.

The floor layer is generally composed of several basic layers such as the surface layer and the roof of the structural layer.

The structural layer is the main horizontal load-bearing component of the building, it can load all the static and dynamic loads above, and then transfer the weight to the walls and columns, the main role of the surface layer is to protect the floor slab and load transfer, in addition to it can also play a role in cleaning and decorating the interior, and also optimize the sound insulation ability of the floor slab, and the ceiling will be attached to the floor or roof below the roof, usually divided into two categories: ceiling and suspended ceiling.

Floor layer considerations

During construction, first marked with the pouring floor slab leveling line, molding, cutting off the powder surface layer at the junction of the wall around the floor slab, depending on which process the wall structure takes, chiseling the wall 100mm 150mm when slotting, when you need to plant reinforcement, drill holes, remove dust in the holes, implant the steel bars into the holes with special structural glue, intertwined vertically and horizontally, two-way single layer, bundled into a net.

The spacing of the steel bars is 150mm, the thickness of the plate is 100mm 120mm, if necessary, depending on the room type structure, add beams and columns, stirrup spacing 150mm 200mm adjust the flat surface, pour concrete, after 7 15 days of curing, it can fully meet the national building standards, otherwise the surface is prone to cracks.

The basic composition of the floor layer can be divided into three parts: the structural layer, the surface layer and the roof.

1. Structural layer: The structural layer is generally a floor or composed of beams and floor slabs; It is the main horizontal load-bearing component of the house, which transfers all the static and live loads and self-weight acting on it to the wall or column, and at the same time it plays a horizontal supporting role on the wall to enhance the integrity and rigidity of the house.

2. Surface layer: It plays a role in protecting the floor slab, bearing and transmitting the load, and at the same time has a very important cleaning and decoration effect on the interior, and can improve the sound insulation performance of the floor slab.

3. Ceiling: The part attached to the bottom of the floor or roof panel can be divided into two categories: direct or ceiling and suspended ceiling.

When the use and construction requirements cannot be met, the floor layer can be added with corresponding structural layers such as leveling layer, waterproof layer, insulation layer, sound insulation layer, etc.
