GENERAL FEATURES OF TELESCOPIC UPRIGHT SYSTEM:
What is Telescopic Mast?
Telescopic Prop System is also known as ''Iron Pole System''. It is one of the most used systems among the formwork scaffolding systems. It can be easily used in many reinforced concrete structures such as floor formwork systems, beam formwork systems, and engineering structures.
Uprights consist of 6.0 mm base plate, 1 piece of 60.0/2.5 mm outer tube, 1 piece of 48.0/3.0 mm inner tube, 60.0/3.0 mm fine adjustment screw and fine adjustment nut welded to the outer tube. The head parts are fixed to the inner tube part by welding.
The heading part varies according to working conditions and preference. There are 4 types of headings: Flat Head, U Head, Beam Head (T Head) and Four-Way Head.
Telescopic Prop; It can be practically adjusted to any working height between 1.75m - 6.00m with the feature of opening and closing the inner pipes with holes at certain intervals inside the outer pipe. It is a system that is easy to use as single elements, has a wide working area and is resistant to continuous use.
Tripod stand elements are used in situations where the working distance is high and there is a risk of tipping over. The tripod is connected to the telescopic pole from the outer pipe section, creating a safe pole system.
Telescopic Scaffolding Materials are produced under the OĞUZHAN® brand in accordance with the TSE EN ISO 3834-2 Quality Conditions Standard for Fusion Welding of Metallic Materials.
The pipes used in the production of telescopic poles are manufactured from pipes that have undergone mechanical and chemical tests and comply with the TSE EN 10219-2 Structural Steel Pipe Standard. The carrying capacity of the telescopic prop system should be determined by static calculations to be made on a project basis according to the installation.
Technical Documents
Telescopic Prop System consists of Base Plate, Telescopic Outer Tube, Telescopic Inner Tube, Fine Adjustment Screw, Fine Adjustment Nut, Adjustment Hook, Head Systems, Tripod Stand (Three legs) and Accessories.
Installation:
The ground where the scaffolding system will be installed is prepared for installation, Telescopic Prop is selected according to the height of the formwork, Telescopic poles are prepared for installation at certain intervals in accordance with the carrying capacity and safety, The inner pipe section is opened according to the required height, Final adjustments are made with the fine adjustment nut and hook and the telescopic prop system is fixed, Tripod stands are added from the outer pipe sections for the safety of the system against tipping, The system is completed by placing the wooden materials and flooring materials under the formwork.
Telescopic Outer Tube:
It is the outer tube element of the telescopic upright system. Outer tubes are manufactured from 60.0/2.50 mm steel tubes as standard. They can also be manufactured according to different wall thicknesses. Their lengths can be 150 cm, 200 cm, 250 cm and 300 cm according to the telescope size. They are welded together with a fine adjustment screw made of 60.0/3.0 mm steel tubes, and they work as a single material in terms of structure. A base plate made of 6 mm sheet metal with an area of at least 15 cm2 is welded together to the bottom of the outer tube.
Telescopic Inner Pipe:
It is the inner pipe element required for adjusting the telescopic upright system to different heights. It is manufactured from 48.0/3.0 mm steel pipes as standard. It can also be manufactured according to different wall thicknesses. Their lengths can be 150cm, 200cm, 250cm and 300cm according to the telescope size. In order to adjust the telescopic upright height, there are coarse adjustment holes with a diameter of 15mm on the inner pipe where hooks are passed at certain intervals. The inner pipes are used by welding them together with the head section from the upper parts.
Fine Adjustment Screw:
It is the element that contains the adjustment mechanism in the telescopic upright system. It is manufactured from 60.0/3.0 mm steel pipes as standard. Its length is 25 cm. The teeth are opened for the mechanism system on the 60.0/3.0 mm pipes. It is fixed with the telescopic outer pipe by welding and combined with the mechanism with the fine adjustment nut. The Fine Adjustment Nut moves up and down on this mechanism.
Fine Adjustment Nut and Hook:
These are the elements that ensure the safety of the connection between the inner and outer pipes in the telescopic pole system. When adjusting the telescopic pole height, the Hook is inserted into the holes on the inner pipe, and this connection is fixed with the fine adjustment mechanism and nut. Both the Adjustment Nut and Hook are effective in keeping the system stable and secure.
Heading Systems:
Heading systems are welded to the ends of the inner tubes. It is the topmost element of the system. Heading types vary according to the working conditions and material preference under the formwork. There are 4 types of headers: Flat Heading, U Heading, Beam Heading (T Heading) and Four-Way Heading. There are no adjustable shaft sections as in the upper adjustment shaft used in other under-formwork scaffolds. In the telescopic system, they are used as a header only on the upper part of the inner tube. In this system, the adjustable part is not the header, but the inner tube part.
Four-Way Header Fastener:
Before the formwork slab elements are assembled, Main Carrier H20s and Secondary Carrier H20s are placed on top of each other. Four-Way Header Fastener also ensures that the Header System and Main Carrier H20s are fixed to each other.
Beam Connection Angle:
They provide the connection between the Main Carrier H20s placed between the heads before the formwork slab elements are placed and the Secondary Carrier H20s placed frequently under the slab. They increase the safety of the formwork system.
Accessories:
These are the materials used to increase the functionality and safety of the scaffolding system. Connection Pipe, Fixed Clamp, Movable Clamp, Four-Way Head Connection Element, Beam Connecting Angle, Plywood, Wooden Beam H20 etc.
