The profiled steel plate-concrete ten combination floor is a slab composed of cast-in-place concrete on the profiled steel plate and configured with an appropriate amount of steel bars.

Forced components that work together as a body. As a new type of structural form, the profiled steel plate-concrete composite floor has the main advantage that this type of slab not only has good structural performance and reasonable construction sequence.

In addition, compared with other slabs (such as concrete slabs, laminated slabs), the profiled steel plate-concrete composite slab has high rigidity, good seismic and fatigue resistance, safety and reliability.

It has many advantages such as convenient construction and operation, shortening the construction period, and good comprehensive economic benefits. In order to improve the efficiency of the use of materials, scientific researchers.A large number of theoretical researches and technical applications have been carried out on the slab-concrete ten-combination floor, and good social and economic benefits have been achieved.

At present, it is widely used in the floor and roof of steel structure and composite structure houses, especially in industrial plants and other buildings. With the continuous increase of steel varieties in my country

, The introduction of relevant technical standards and the continuous improvement of supporting technologies, the Le-shaped steel plate mixed sea ten-combination floor will have its desired co-working characteristics and stress performance.

It has been widely used in the fields of construction and bridges, and has a very broad prospect.

In the 1950s, profiled steel began to be used in construction projects, and in 1960, the first use of stud penetration was in the Federal Court Building in Brooklyn.

The explosive Le-shaped steel plate concrete ten-combination floor system, in the 1960s, Japan and some countries in Europe and the United States began to apply the profiled steel plate concrete ten-combination plate to the dry.

At that time, the profiled steel plate was only used as a permanent formwork and construction work platform. Later, it was found that concave-convex ribs or different forms were extruded on the profiled steel plate.

The corrugated grooves can improve the adhesion performance between the steel plate and the mixed group, so that the two can work together, so that the steel plate can be stressed like a tensile steel bar, and then the

A lot of experimental research and theoretical analysis. Since then, European and American countries and Japan have successively formulated articles, regulations or regulations for profiled steel plates and concrete composite panels.

In the mid-1980s, profiled steel plates and concrete ten-combination plates were introduced into our country, and the majority of scientific and technological workers carried out a lot of research work on their basic mechanical properties.

The metallurgical industry standard "Steel-concrete composite floor structure design and construction regulations" (YB9238-92) was formulated.

Technical Regulations", the national standard "Steel Structure Design Specification", and the electric power industry standard "Steel Concrete Composite Structure Design Regulations", all make the composite floor slabs.out the relevant design regulations and requirements.

These specifications and regulations have laid the foundation for the application of profiled steel plate-concrete composite floors in various projects. With the continuous deepening of a large number of theoretical research and application practice.

It has greatly promoted the application of profiled steel plate-concrete composite floor in many fields such as high-rise buildings, industrial plants, large-span structures, and large-scale bridge structures.

to a wide range of applications.

Development Trend

The development of basic materials will further promote the improvement of the performance of the profiled steel plate-concrete composite floor. For example, the profiled steel plate made of coal gangue concrete-coal gangue mixed.

Condensation of ten-combination panels can reduce self-weight, save materials, reduce construction costs and speed up construction; using high-strength, high-temperature-resistant and corrosion-resistant steel can further reduce.

The amount of steel used increases the fire resistance and durability of components, thereby reducing fire protection costs and maintenance costs;

The improvement of the design and production process of the profiled steel plate will make the bonding ability between the concrete and the profiled steel plate stronger, and the stress performance and deformation of the joint work will be more reasonable.

For example, the use of deep rib profiled steel plates can save the secondary beam arrangement required for composite plates, and the plate span can reach 6m without support. If a certain number of temporary

The supporting span can reach 9m, which greatly supports the development of the building towards a larger span;

The improvement of the design calculation method and the improvement of the calculation method will further improve the accuracy and efficiency of the calculation, and make the design more reasonable and convenient

With the continuous deepening of research, the understanding of the mechanical properties of the profiled steel plate-concrete composite floor will be more comprehensive, so that the comprehensive performance of the system during its service life will be safer and more reliable.
