GENERAL INFORMATION

The space cage systems are three-dimensionally formed by fixing the steel joints, which are welded to the two ends with conical parts and called steel rods, with steel bolts inserted into them. All of the production is designed to be prepared in the workshop and assembled on the site. The system consists of pipe, sphere, bolt lovers and support elements

Space Lattice system rods

The material of the rod pipes is the ST37.2 steel according to DIN 17100 (EN 10.025) norm (article no.1.0037). Pipe diameters can range from 42 mm to 219.1 mm depending on design requirements.

The conical parts are made from the same material as the pipes. The cones filled up to 60.3 mm cap are turned from the filled material and larger cones are formed by hot forging.

The cones are welded to the pipe ends using the SG2 type welding wire and by the gas-in-pipe (MIG) method in accordance with DIN 8569, DIN 4100, DIN 4115 (EN 759, EN 440, EN 758, EN 1668) norms.

Each bar is manufactured with holes that can be inserted and clamped in the bolts during installation. In the case of rods up to 60.3 mm in diameter, these holes open to the sides of the pipes at larger diameters.

CONICIAL TYPES

PIPE TYPES

SPHERES

The combination spheres are made by hot forging from 1040 steel in accordance with DIN 17200 (EN 10.083) norm. Sphere diameters vary between 60 mm and 190 mm depending on the design.

Threaded bolt holes are drilled in the spheres to secure the rods. The diameters and angles of the holes are determined by the shape and other properties of the space system. To increase the contact surface between the spheres and the cones, surface modification is made on the holes.

BOLTS

Bolts of 8.8 or 10.9 in accordance with DIN1654 and DIN17200 (EN 10.083) norms are used in combination of space system components. The bolt diameters range from 12 mm to 48 mm and the threads are dimensioned according to DIN 13 ISO types.

The 8.8 quality bolts are from 34Cr4 material with a minimum tensile stress of 80 kg / mm², a minimum yield stress of 64 kg / mm², and a travel time of 12%.

The 10.9 quality bolts are made of 41Cr4 material with a minimum tensile stress of 100 kg / mm², a minimum yield stress of 90 kg / mm ², and elongation of 9%.

HANGERS AND OTHER STEEL ELEMENTS

Other elements of steel such as column, cross, fascia etc. are manufactured in I, U, C forms or boxsectioned St37.2 steel material.

BEARINGS

Static and sliding bearings are made from St-37 or St-52 material to minimize the movement of heat exchange and other causes whilst ensuring overall stability of the system. The shape and dimensions of the supports can vary according to the system characteristics.

Protection against corrosion

The rod surfaces which are cleaned by mechanical and chemical methods are preferably coated according to one of the following methods:

In the desired RAL color,
Electrostatic powder paint in the desired RAL color,
Hot dip galvanized coating,
Electrostatic powder paint on the desired RAL color over hot dipped galvanized.
Spheres and bolts are electro-galvanized coated to a thickness of 15 microns

Assembly

The installation of the space frame systems can be done in one of the following ways according to the system and site characteristics using simple hand tools:

The entire system can be mounted on site and replaced with a crane.

The entire system can be installed on site with the help of partial scaffolding..
Once a part of the system is prepared in place and placed in place with a crane, the installation can be continued in the air.

Advantages of Space Cage System

Space lattice systems are formed by joining axially loaded rods at node points in a three-dimensional plane. The bar elements are formed from spherical elements in the knot points by conical parts welded to the ends of the tubes. The system consisting of pipes and spheres is connected to each other by bolts. Loops made from profiles I, U, C or box sections from sphere are connected and ready for system coating

Some of the advantages of space cage systems are mentioned below.

Since space cage systems operate in two dimensions in three dimensions, they provide economical solutions in wide openings.

With the space cage system it is possible to pass through openings up to 100 m without columns..
Space lattice systems provide a wide range of flexibility in the choice of support spaces and allow for convenient solutions in closing areas and volumes in various geometries..

Manufacture-installation times are short because they are made of prefabricated elements. The investor provides opportunity to go into operation as soon as possible..
Since the manufacturing is made up of prefabricated elements, transportation to the distances can be easily achieved
Concrete is thinner than prefabricated and steel constructions. Therefore, it will provide economy in base and column sizes.

Since it is lighter than the other structural systems and the earthquake loads on it are low, the space frame system roof constructions for earthquake zones are indispensable.

It does not need to be covered with a suspended ceiling because of its decorative appearance. .
Electricity, heating and ventilation systems also do not require an additional supporting system.

Due to its decorative structure it is very convenient to be used in lighting structures. The glass is made of polycarbonate type transparent coating carrier

Space lattice system architectural solutions offer many different alternatives. Piramit, triangle, vault, shell and cylindrical structures and so on.

STEEL ROOF

provided by the steel roof, the available space is also increasing. Steel construction roof systems also provide convenience for modification and modification. The parts that are manufactured on site or in the workshop are fast to install. Compared to other construction systems, installation can be continued despite weather conditions. For this reason, construction time is short.

Features :

It is cost effective..
Insulation is easy..
The building adds aesthetic appeal..
Increase available volume..

QUICK INSTALLATION

Since parts are usually made in the workshop, they do not have to work very long in the construction site. The reinforcement is easy and fast in case of the necessity of the reinforcement of the parts. Material waste is low, the process will be fast if the construction must be removed for any reason. The dismantled system can be constructed with the same materials again with very little loss elsewhere. Systems with large openings can easily be passed with steel, which can not be passed by other building materials. Apart from the height at which the structure can be constructed and some construction systems, a correct and well designed design can be installed without the necessity of scaffolding. After the manufacturing is done considering the site speed in the workshop environment, it is assembled on the construction site. The main element in the installation is the installation of the whole system with bolt button connection. Produced from galvanized steel material. Thanks to the insulation technique applied, it protects the building from water and corrosion and it is ensured that the building is long-lasting because fire safety is at the top level

WHY STEEL STRUCTURE? ?

"Why steel construction?" There are various reasons behind preferring the steel structure to the reinforced concrete structure. Rapid manufacturing, breakthrough resistance are the leading reasons. The steel construction structure reduces the loss of life and property in disasters and provides security. Steel factories, industrial buildings, sports facilities, hangars, warehouse steel constructions are frequently used structures. Light or heavy steel is preferred according to the requirement of the progeny. In industrial constructions, heavy steel is preferred in general, and the transportation force is suitable for industrial needs. As steel production is under control, the safety factor is high. The elasticity of the steel material is 20 on average, and 10 times larger on concrete than on concrete.

Due to its high strength, material removal is low. Parallel to the lack of material, the weight of the structure falls and ultimately the structure has a lower shear force. That means a lower earthquake load. In addition, due to the high flexibility, it is possible to obtain appropriate results where bending strength is required. The uncertainties in construction, the constantly growing construction times, cost increases, the lack of qualification and the like problems. Furthermore, due to the grounding feature of the steel structure, it does not carry the risk of lightning. Finally, steel construction will be important for health. The magnetic field that exists in the natural environment does not diminish the effect, and for many years it helps the body to work in a healthy way. Thanks to its high heat and sound insulation, it helps me to be influenced by external influences such as hot, cold and sound.
