Telescopic stand: characteristics and application

Telescopic stand is the main supporting elementformwork and is used in the construction of reinforced concrete monolithic ceilings. Work can be carried out at a wide temperature range and at an altitude of up to 4.5 meters. The device is designed for concreting of various floors, including inclined, straight, supplemented with capitals and reinforced concrete beams. Most often, the telescopic pole is used in the construction of residential buildings.

The connecting frame and the foldable tripod allowinstall the system and bring it to the vertical position. For the laying of the beam and beams, different univilks are used. All these components ensure safety during construction and simplify operations.

Telescopic racks: characteristics

These support elements It is possible to carry out different types of formworkoverlapping, for example, round, cantilever and rectangular. In this case, there is no need for special aggregates, since all work is done using a standard set of composite elements. The prefabricated floors can have a height of up to 5 meters, but still it is recommended not to exceed the parameter of 4-4.5 meters.

It is worth noting the main characteristics that the telescopic stand has:

  • The thread on the tensioner is produced fromquality material by the method of plastic deformation. This technique prevents the loss of strength, which is typical for threaded threads. As a result, the service life of the tensioner is increased.
  • The rack is economically advantageous, which is especially noticeable with residential construction.
  • Presence of an anticorrosive covering.
  • Installation of the structure at the required height is carried out with the help of a simple and convenient adjustment system.
  • A small weight of the telescopic pillar, which directly depends on the height of the structure. For example, the device with a height of 3.1 m weighs about 11 kg, and at an altitude of 4.5 m the mass reaches up to 15 kg.

Features

Today monolithic buildings are increasingly being built withthe height of the ceilings is more than 4.5 meters. In this regard, there is a need for quality equipment for the creation of formwork. As an alternative, a frame formwork system is used, the construction of which consists of a list of interconnected parts.

The telescopic stand can have a differentheight, which is varied by moving the inner tube, 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 made it possible to distribute the load evenly.

Design

The components of the racks are represented by the following details:

  • the wedge unit necessary for the dense fixation of horizontal and vertical elements;
  • Horizontal parts: braces and crossbars, providing the connection of the main parts of the structure;
  • vertical elements: jacks and racks, which accounted for the loading formwork table.

Due to the connection of all parts there is noprobability of exceeding the load on individual elements, since the weight is distributed evenly throughout the device. This ensures reliability and resistance to point high loads.

The wedge assembly is formed in such a way that whenthe presence of a load significantly exceeding the established, the structural components are deformed, and the probability of destruction of the system is markedly reduced. Due to this, it is possible to prevent avalanche destruction of the formwork, in which some of the destroyed elements pull adjacent ones, by detecting and restoring the damaged node. In this case, telescopic racks for formwork overlap can be quickly adapted to the existing operating conditions.

Benefits

Convenience and ease of installation are achieved due to the following characteristics:

  • the use of large composite elements;
  • fast fixation of the wedge assembly;
  • small number of parts.

Long service life, resistance to stress, quick and easy installation, relatively low cost of structures allow to reduce the cost of concreting and speed up the work.
