What is Composite Structure?

The most frequently used feature in Building Technologies is to use different building materials together.

The most important feature of the composite structure is the use of concrete and steel together. Various combinations of steel with high tensile strength and flexibility and concrete with high compressive strength and corrosion resistance are used and applied in steel + concrete composite structures in the world.

With the composite construction method, it is possible to combine the positive properties of steel and concrete without any hindrance.

Stud Welding Applications in Structures

Composite Building Sector has an important place in the construction sector.

The advantage of fast assembly, independent of weather conditions, allows the building to be put into use before the planned date.

It allows more flexible use and more usage areas in areas where wide columns are not needed.

Since the beam dimensions are low compared to reinforced concrete, it allows more floors to be built for the same building height due to the thinness of the floors despite wide openings.

Composite Floor Trapeze Under Concrete

Sheet Metal Advantages

Concrete Trapezoidal Sheet acts as a permanent mould.

It is very easy to put into place compared to other mold materials. There is no problem of erecting and dismantling scaffolding.

Concrete Trapezoidal Sheet It accelerates the construction time and creates a safe system. After the concrete, the underside remains clean and an aesthetic appearance can be obtained by painting the steel sheet underside or leaving it in bright sheet color.

Concrete Trapezoidal Sheet The cross-section acts as reinforcement, which is usually sufficient for the positive moment.

Additional reinforcement can be used in the flooring to provide resistance to dust and temperature changes or to provide continuity in the internal supports.

anchored to steel beam concrete trapezoidal sheet, for pressure head of beams under construction

It acts as a lateral support.

Under Concrete Trapezoidal sheet height, which can vary with sheet type, provides concrete economy up to 40 liters/m².

This reduction in the slab's own weight provides a significant reduction in dead load carried by the structure and foundations of around 1.0 kN/m².

Since the sheet cross-section used carries more load, the composite slab thickness becomes less than the reinforced concrete slab thickness. Less load is placed on the structure. Under Concrete Trapezoidal Sheet is very easily transported and stored.

The trapezoidal sheet metal under concrete required for a 1500 m² slab can usually be transported with a truck.

Concrete Trapeze 38/151 Features

Concrete Trapeze 38/151 form is a form developed for special projects.

It is designed to be used where low concrete height is required. It is also used in mezzanine floors of residential steel structures, mezzanine floors where light storage will be made, and office mezzanine floor steels.

Trapezoidal sheet 38/151 form is produced in the same machine as the trapezoidal roof sheet.

Concrete Trapeze 38/151 Dimensions

Concrete Six sheet is in 38/151 form. The 38 mm measurement in the form is the pitch height measurement.

The measurement of 151 mm in the form is the pitch measurement. Pitch means the starting axes of the same form that follow each other. The net closure area of our 38/151 form of under-concrete trapezoidal sheet product is 91 cm.

The net closure area in trapezoidal sheets represents the area to be closed side by side during assembly.

The starting and ending axis of the form is taken as a basis rather than the complete width of the sheet.

For example, in 38/151 – 91 cm concrete, the useful closure area where six trapezoidal sheets will be closed side by side is 2×91 = 182 cm.

38-151 UNDER CONCRETE TRAPEZE SHEET- FOUNDATION SHEET

Concrete Trapeze Installation

Under Concrete Trapeze 38/151 is laid on top of the steel structure, perpendicular to the direction of the steel beam.

Concrete holding sheet should be placed in the open areas of the steel structure.

The thicker the concrete holding sheet flooring thickness, the higher it should be.

Concrete retaining sheets, which also serve as a kind of formwork, are generally bent 90 degrees from 2, 2.5, 3 mm sheet metal and welded onto the steel.

After covering all open areas on the steel structure with a concrete retaining sheet, the sheet must be fixed to the steel structure. Although it is usually fixed with a key head bolt, the truth is to assemble it with a Stud nail.

Stud nail is welded by creating an electric arc on the steel structure without using any electrode wire or gas with its unique welding machine.

As static loads decrease, more economical sections emerge. Composite floor trapezes can be easily transported, stored and produced in desired sizes.

The gaps between the steel beam and the composite floor trapezoidal ribs are fire-electric, etc. It allows easy installation of the installation.

Galvanized steel sheets are extremely resistant to corrosion.

In order to increase this strength, it is suitable for paint applications. Sheets resting on steel beams during construction are a safe working platform for workers and materials.

Since it does not require formwork, there are no formwork materials, scaffolding and labor costs.

Composite floor trapezes working in full interaction with concrete act as reinforcement.

Reinforcement quantity is reduced.

Although it is lighter than concrete slabs of equivalent height, it has a higher load carrying capacity.

Under-Concrete Trapezoidal Sheet It is among the building elements that eliminate the cost of formwork in composite structures and minimize the use of concrete thanks to its high strength.

Concrete trapeze can easily close wide openings in suitable thicknesses.

Determination of suitable thicknesses is based on static calculations.

The fixed and live loads of each structure must be calculated.

The most reliable way to minimize costs is the static calculation.

With these calculations, you will make the structure lighter and minimize the investment cost.

As it is known, the hardness, flexibility and strength of materials such as Steel, Concrete and Wood used in composite structures are very different from each other.

In steel structures built alone, concrete is generally preferred in terms of cost and architecture for intermediate floors. It is one of the first products preferred to reduce the cost of concrete structures and to facilitate workmanship.

Due to the surface structure of the sub-concrete trapezoidal sheet, which provides integrity, it provides a solid and strong floor by combining concrete and steel.

By attaching the slab to the steel by means of Stud nails, it provides integrity with the structure. A steel mesh is thrown on the trapezoidal sheet under concrete with stud nails, and it turns into a completely compact structure.

Concrete Trapezoidal Sheet Dimensions

The technical information of Concrete Trapezoidal Sheet, which we have produced for different building alternatives and widths, is given below.

Under-concrete trapezoidal sheet is preferred according to the situation in the structure in which it will be used.

For example, in industrial facilities, 60/940 and 75/750 forms are generally preferred.

38/151 form is preferred for light mezzanine floors.

Of course, the sheet thickness and form should be approved according to the report in the static calculations, which is essential.

Benefits of Trapezoidal Sheet Under Concrete

It is easy to install due to its structure. Since it is produced according to the desired dimensions, it can be assembled without wastage. Thanks to the special production lines, it is possible to manufacture according to different dimensions according to your settlement dimensions in the project.
Since the usage areas are generally on the steel structures, there is no need for equipment such as scaffolding and baskets for assembly. Depending on the condition of the building, it can be serviced to a single point with a crane, and costs all cranes at once.
It saves time in terms of ease of assembly.
Due to its cross-sectional structure, post-concrete flexibility is minimized. By fixing the trapezoidal sheet metal, which is mounted on the steel, to the steel, the horizontal and vertical connection of the structure is ensured. In this way, we minimize the flexibility in the structure.
