LSTC Technology

Erection of Easy Raising Buildings

The LSTC technology is used for erection of residential constructions (cottages, low-storeyed semidetached houses, town-houses, etc) and commercial constructions (shopping centres, office buildings, working areas, hotels, refueling stations, etc).

A light steel thin-walled construction doesn’t loud the building foundation. Due to it it’s possible to erect houses on unstable ground. It’s a great advantage for a reconstruction (including a reconstruction of very impaired buildings), building in seismic dangerous regions and in case of a close city building up without use of hoisting machines.

Thanks to lightness of every element, size accuracy, marking and circumspect deigns, frame assembling in the building site looks like assembling of a big meccano. A team of 3—4 people is able to erect a house frame by the area of 150 up to 200 m² during 2 or 3 weeks. As all elements are joined with self-drilling screws, only an electric drill and a screwdriver are required for assemblage.

At first a virtual house model is designed and then according to it a material register and production and line management program are worked out. All elements (that can be more than 5000) are packed and marked in conformity with the project documentation. In the building site mounters get a set of assembly drawings and wiring cards. A through marking makes possible to find necessary elements quickly and to install a frame accurately.

Reduction of building terms and, as a consequence, its cost depends on the degree of the building process optimization where for multiple erecting (for example a cottage village or town-houses) it’s possible to use aggregative assemblage of construction elements previously produced in plant conditions.

Advantages of Easy Raising Buildings

• Reliability and Durability – a high degree of reliability of LSTC buildings is provided for steel profiles size stability. Besides steel profiles don’t undergo the influence of biological and temperature-humidity processes in contrast to wood. A building life-time is determined with tenure of employment of metal frame, paneling, warmth lagging, etc. According to the British Steel Research in conformity with natural zinc issue a life-time of LSTC construction (profiles are made of galvanized steel with rate of zinc application 275 g/m2) is about 100 years.

• Wide architectural possibilities and fields of application. Constructional ability to overlap bays up to 14 m without intermediate bearings for roofing and up to 8 m for floors, ability to place services inside frame walls and overlapping allow using inner space to the limit and creating original planning. As for revetment, any material can be used depending on customer’s request and economic expediency: brick, molded board, beam, perforated sheets, variants of warmed pargeted facades as well as a great number of aired facades with the use of glass, stone, etc

• Effective Energy-Saving. Effective warmth-lagging inside a thermo-profile frame sets up the coefficient of resistance of heat transmission up to 5.6 without taking possible facade warmth-jacket into consideration. Thanks to such characteristics expenses during exploitation are considerably reduced and network loading is diminished. High energy-saving index allows using LSTC for the economic building even in conditions of the Extreme North.

• Ecological Purity. Correctly designed and erected LSTC buildings don’t have the syndrome of a “sick house” connected with superfluous humidity. And inner area is a safe ergonomically and ecologically comfortable sphere due to good noise insulation, moisture resistance and air tightness. One shouldn’t forget that a convenience of such a building is assured with correctly provided airing system.

• Seismic and other dynamic load tolerance. Buildings where LSTC is a basic bearing system are able to resist seismic load up to 9 points of the Richter scale. It’s possible thanks to steel frame flexibility where extra ties and connections are used.

• Fire resistance. Fire resistance of the construction is assured with boarding plate material. And a number of layers may be set in conformity with concrete specific fireproof requirements.

• Low exploitation expenses. Buildings erected on the base of LSTC have stable sizes, good protection from biological and temperature-humidity processes. They are durable, energy saving and not so expensive in repairing (when tenure of employment comes to its end or when thorough repairs are required) comparing to buildings made of classic materials.
