Telescopic stand It is the main supporting element of the formwork and is used in the construction of reinforced concrete monolithic floors. Work can be carried out at a wide temperature range and at a height of up to 4.5 meters. The device is designed for concreting various floors, including sloping, straight, supplemented with capitals and reinforced concrete beams. Most often, the telescopic rack is used in the construction of residential buildings.
A connecting frame and a folding tripod allow you to install the system and bring it into a vertical position. Various univilki are used for laying timber and beams. All these components provide safety during construction and simplify work.
Telescopic racks: characteristics
These supporting elements allow formwork of various types of floors, for example, round, cantilever and rectangular. At the same time, there is no need for special units, since all work is carried out using a standard set of composite elements. The erected ceilings can have a height of up to 5 meters, but still it is recommended not to exceed the parameter 4-4.5 meters.
It is worth noting the main characteristics that the telescopic stand has:
- The tensioner is made of high-quality material by the method of plastic deformation. This technique prevents loss of strength, which is typical for threaded threads. As a result, the period of operation of the tensioner increases.
- The stand is cost-effective, which is especially noticeable in residential construction.
- The presence of anti-corrosion coating.
- Installation of the structure to the required height is carried out using the simplest and most convenient adjustment system.
- Light weight telescopic stand, which depends on the height of the structure. For example, a device with a height of 3.1 m weighs about 11 kg, and at a height of 4.5 m, the mass reaches 15 kg.
Features
Today, monolithic buildings with floor heights of more than 4.5 meters are increasingly being erected. In this regard, there is a need for high-quality equipment to create formwork. As an alternative, a frame formwork system is used, the design of which consists of a list of interconnected parts.
The telescopic stand can have a different height, which varies by moving the inner pipe, supplemented by a hole with a lock in the form of a lock. Achieving the required level is possible due to the movement of the external threaded coupling. The design provided the ability to evenly distribute the load.
Design
The components of the racks are represented by the following details:
- wedge assembly required for tight fixation of horizontal and vertical elements;
- horizontal parts: braces and crossbars ensuring the connection of the main components of the structure;
- vertical elements: jacks and racks, which bear the load of the formwork table.
Due to the connection of all parts, there is no possibility of exceeding the load on individual elements, since the weight is distributed evenly throughout the device. This provides reliability and resistance to point high loads.
The wedge assembly is formed in such a way that, when there is a load significantly exceeding the installed load, the structural components are deformed, and the probability of system failure is noticeably reduced. Due to this, it is possible to prevent avalanche destruction of the formwork, in which some destroyed elements pull adjacent ones by detecting and repairing the damaged unit. At the same time, telescopic racks for flooring formwork can be quickly adapted to existing operating conditions.
Benefits
Convenience and ease of installation are achieved due to the presence of the following characteristics:
- the use of large constituent elements;
- quick fixation of the wedge node;
- a small amount of detail.
Long service life, resistance to loads, quick and easy installation, relatively low cost of structures can reduce the cost of concreting and speed up the work.
