Description

Technical Field

[0001] The utility model belongs to the technical field of floor structures and relates to a light steel composite lightweight floor structure. Background Art

[0002] With the development of society, building industrialization is imperative. Due to defects such as slow construction speed, high weight, high labor intensity, and complex processes, various traditional building floors simply cannot meet the needs of building industrialization development. It is imperative to develop lightweight floors that are light, convenient, and high-strength and meet the needs of industrialization development.

[0003] For existing lightweight floors, for example, Chinese patent literature discloses an ultra-light and high-speed floor for building industrialization [Patent No.: 201010197289.2; Publication No.: CN102277912A]. It consists of a long-strip profiled steel sheet as an overhead keel plate with the long side in the same direction as the direction of the pressure groove. A continuous load-bearing steel sheet is laminated on the upper and lower surfaces of the profiled steel sheet to form a hollow strip board with a corrugated cardboard structure. Several rows of buckling limit plates for restricting the deformation of the inclined side plates of the profiled steel sheet grooves are arranged in the hollow grooves. This ultra-light and high-speed floor is a floor structure assembled from such strip boards. First, an energy-saving sound insulation and shock absorption material is laid on the floor surface, and a high-strength panel is installed on the energy-saving sound insulation and shock absorption material to form a floor; an overhead keel is installed under the floor, and the laying of electric wire pipes is completed. Finally, a ceiling board is installed under the overhead keel, and the installation of electric wire boxes is completed at the same time to form the top surface of the next floor.

[0004] This kind of ultra-light and high-speed floor structure is a modern new building floor that reduces the weight of the building and improves the construction speed. However, this kind of ultra-light and high-speed floor structure is composed of a profiled steel sheet and two layers of load-bearing steel sheets to form a floor, and an energy-saving sound insulation and shock absorption material is laid on the floor surface. They are independently and separately arranged, and the structure is relatively loose. Moreover, the combination effect of the floor and the sound insulation layer of the ultra-light and high-speed floor is poor, the sound insulation layer is easy to fall off, and the sound insulation effect is average. Summary of the Invention

[0005] The purpose of the present utility model is to address the above problems existing in the prior art and propose a light steel composite lightweight floor structure. The technical problem to be solved is how to make the floor structure compact while having good sound insulation and heat insulation effects.

[0006] The purpose of the present utility model can be achieved by the following technical solutions: A light steel composite lightweight floor structure includes a corrugated floor slab. It is characterized in that a bottom plate is fixedly connected to the bottom of the floor slab, a base plate is fixedly connected to the top of the floor slab, a filling space is formed between the floor slab, the bottom plate, and the base plate, and a material with sound insulation and heat insulation functions is filled in the filling space to form a sound insulation layer. A concrete layer is fixedly connected by casting on the top of the base plate.

[0007] The floor deck is made of steel. Compared with reinforced concrete structures, the floor deck is lighter in weight while having sufficient strength. Due to its corrugated shape, the floor deck has a better shock absorption effect, avoiding floor vibrations. At the same time, because the floor deck is corrugated, environmentally friendly materials, such as formaldehyde-free environmentally friendly cotton, can be filled in the filling space between the floor deck, the bottom plate and the base plate to form a partition layer. The floor deck and the partition layer of this floor structure are integrated, with a compact structure, enhancing the strength of the floor structure. The partition layer has the functions of sound insulation and heat preservation, reducing noise, maintaining room temperature, and having a certain fire prevention effect. A concrete layer is cast and fixedly connected to the top of the base plate, and the concrete layer serves as the floor surface, making the floor have sufficient strength.

[0008] In the above-mentioned light steel composite lightweight floor structure, the floor deck includes a number of bottom layers that are flat at the bottom and a number of top layers that are flat at the top. The bottom layer abuts against the bottom plate and is fixedly connected to the bottom plate through fasteners. The top layer abuts against the base plate and is fixedly connected to the base plate through fasteners. This structure enables the floor deck to better connect the bottom plate and the base plate, enabling the floor deck, the bottom plate and the base plate to be better integrated into one body, ensuring the strength of the floor structure. The fasteners can be shear studs.

[0009] In the above-mentioned light steel composite lightweight floor structure, the floor deck is composed of a number of profiled steel sheets. The top of the profiled steel sheet has the top layer. The two sides of the profiled steel sheet are inclined downward and outward from top to bottom. The bottom of the profiled steel sheet is bent outward to form a flange, and two adjacent flanges form the bottom layer. This structure makes each part of the floor structure relatively independent, enabling the floor deck to better disperse and resist various loads of the floor and better absorb vibrations.

[0010] As another case, in the above-mentioned light steel composite lightweight floor structure, the floor deck is composed of a number of channel-shaped steel sheets. The top of the channel-shaped steel sheet has the top layer. The two sides of the channel-shaped steel sheet are arranged vertically. The bottom of the channel-shaped steel sheet is bent outward to form a flange, and two adjacent flanges form the bottom layer. The two sides of the channel-shaped steel sheet are perpendicular to both the top layer and the bottom layer. This structure makes each part of the floor structure relatively independent, enabling the floor deck to better disperse and resist various loads of the floor and better absorb vibrations.

[0011] In the above-mentioned light steel composite lightweight floor slab structure, the concrete layer includes a steel mesh and EPS concrete. The steel mesh is laid on the top of the base plate, and the EPS concrete is poured on the steel mesh and solidified to fix the concrete layer to the base plate. The built-in steel mesh enables the concrete layer to have better tensile resistance, effectively preventing the problem of floor slab cracking. At the same time, EPS concrete is used. EPS concrete is an innovative material that combines the strength of traditional concrete and the lightweight and heat-insulating characteristics of EPS, greatly reducing the weight of the concrete layer, and thus reducing the weight of the floor slab structure.

[0012] In the above-mentioned light steel composite lightweight floor slab structure, the shape of the mesh holes of the steel mesh is a parallelogram, which stabilizes the performance of the steel mesh and provides sufficient tensile resistance.

[0013] In the above-mentioned light steel composite lightweight floor slab structure, the bottom plate has a fire prevention function. The bottom plate can be made of fireproof materials to improve the fire prevention effect of the floor slab.

[0014] In the above-mentioned light steel composite lightweight floor slab structure, the base plate is an OSB board. The OSB board has high environmental protection performance, good moisture-proof performance and good stability.

[0015] In the above-mentioned light steel composite lightweight floor slab structure, a decorative layer is laid on the top of the concrete layer. The decorative layer can be adjusted according to needs to improve the practicality and aesthetics of the floor slab.

[0016] Compared with the prior art, a light steel composite lightweight floor slab structure provided by the present utility model has the following advantages:

[0017] 1. The floor slab bearing plate and the partition layer of this floor slab structure are integrated. The partition layer is located between the floor slab bearing plate, the bottom plate and the base plate, making the floor slab structure compact, improving the stability of the partition layer, and enabling the partition layer to have better sound insulation and heat insulation effects.

[0018] 2. The floor slab bearing plate of this floor slab structure is composed of multiple profiled steel plates and is relatively independent, enabling the floor slab bearing plate to better disperse and resist various loads of the floor slab, better absorb vibrations, and reduce the weight of the floor slab structure.
