Beams, general information
|
Beams are classified into main beams and secondary beams, roof beams and floor beams. Sections of beams come in modular dimensions; beam length and value of pre-stressing for long-span beams are determined separately for each project, which facilitates in defining the optimal reinforcement of structures. |

During installation, large elements of precast reinforced-concrete structures are positioned over elastomeric pads (made of neoprene rubber) located in supporting points. This is necessary to ensure even distribution of loads within the entire bearing area. The effective bearing length is defined by the boundary bearing stress – both in joint elements, and in the pads, with allowance for tolerances and possible spalling in corners. |

The neoprene pads can withstand the following maximum loads:

Embedded parts are metal parts embedded into reinforced-concrete structures and intended for further attachment to other structures. The embedded parts are classified into the following types:
|

Protruding anchor bars | |
Location of lifting elements in reinforced-concrete structures is dependent on minimal structural deflections occurring in lifting. The number of lifting elements is taken as +1 out of estimated number, however, along symmetrically to axis of structure. Lifting of long-span structures is done using cross frames; this requires the least angle of 600 between lifting slings and structure. When in storage, beams shall be supported in the same places as intended for in-operational support.

Rectangular beams (girders) are mainly employed as intermediate floor beams. Such beams are manufactured of both pre-tensioned and non-tensioned reinforced concrete. The Plant also offers 1.020 series girders of 450 mm with a 6-m span. | ||||||||

Intermediate L- and T-shaped beams are used as standard floor beams. The flange located in the upper section allows for reduction of beam depth, thus making such beams a more expedient solution for civil buildings, trading- and entertainment centers.

Si-beams (hip beams with double-T section) are used a floor beams in buildings of considerable column-to-column spacing: e.g. production buildings, storage facilities, selling areas, etc. The slope of top beam surfaces may range from 1:26 to 1:33, or, may be altered in accordance with particular design solutions. The double-T section is the typical and most rational choice for pre-tensioned beams. The fire-resistance rating of Si-beams can be as high as 120 minutes. |

Double-T beams are employed as horizontal roof beams in long-span buildings, and as floor beams intended for heavy load. The double-T section is the standard and most rational solution for pre-tensioned beams. The fire-resistance rating of double-T beams can be as high as 120 minutes. |

Crane-runway beams, 6 m in length (with 800-mm high T section) and 12-m beams (with 1200-mm double-T section).
Depending on design solutions of particular production buildings, beams may be designed and manufactured according to customer specific requirements, and the type of lifting mechanisms. During installation, crane-runway beams are bolted to columns, followed by subsequent welding of beam’s embedded parts to those in columns. The flanges of beams feature special bores with 750-mm spacing intended for fixation of rails. The bores are fit with embedded metal tubes as a means of concrete protection against destruction that may result from transfer of loads occurring in hoisting. . |

| The beam-to-column connection is made by positioning the beam on the column head. Beams are installed on anchor bolts, and tightened by nuts with metal gasket spacing. Neoprene pads are positioned in points of support prior to installation of beams; this is intended as a measure against destruction of beam and column edges. | ||
