Definitions

• the invention relates to house construction, namely to modular houses assembling.
• Modular houses construction has recently grown in the world.
• Modules are wooden or metal frames containing separate units with roof and floor panels.
• Inner frames contain channels for electricity, heating systems and water pipes.
• House assembling starts with the main frame assembly which is followed by fixation of wall panels, windows, doors, floor and ceiling. Normally wall, floor and ceiling panels contain heat isolating layers.
• the present invention system is based on use of a steel main frame.
• Use of such a frame is described in European Patent 0639677 however the structure design in this patent can be improved since its practical implementation is difficult, and time consuming during planning, pre-production and assembling on construction site. Besides, it provides limited alternative floor plan options, does not ensure high heat and sound isolation characteristics, is expensive, lacks environmental friendliness and requires high material consumption.
• the advantage of the construction system in the present invention is that using few pre-made construction units and only seven types of specially designed steel columns it is possible in a one click operation to connect from one to up to four different floor modules and from one to up to four different roof/floor separating modules. Such an operation can be repeated infinitely to create an unlimited quantity of different floor plan designs using only a limited quantity of construction units.
• the second advantage of the proposed system is that a carefully designed assembling sequence, the system design and special columns allow to construct a flexible, strong, wind and earthquake resistant building with very good heat and sound isolating characteristics at a very low cost and using only a few core materials. Its advantage is also time saving construction, diminishing construction materials consumption, reducing construction garbage quantity, requiring less transportation (environmental friendly), providing unlimited construction possibilities and high heat and sound isolation.
• the present invention is aimed at creating a new method of steel frame modular houses construction ensuring a superior sound, air pressure tests and heat isolation, rapid assembling speed and reduced construction costs. The method does not envisage welding while vertical columns are used for connecting floor/floor supporting/roof units through one single action.
• Horizontal steel elements are frames of at least three different configurations (floor, floor supporting, and roof) with transversal supporting beams.
• Vertical steel elements are one- storey columns creating a set of columns with various configurations.
• Outer isolation panels are fastened to the main structure from the outside independently from inner wall panels creating a sound and heat isolating air gap between inner and outer panels.
• the horizontal steel frame has a U-shaped profile and transversal supporting beams are fastened to the frame through sound isolating brackets with sound isolation material and they hold to the frame due to their weight and friction.
• the system has supporting side beams connecting horizontal frames with columns.
• the set of columns consists of:
• the outer wall panel is connected to the horizontal steel frame that through a sound isolating bracket, floor or roof panel and two L-shaped brackets also attaches a sound isolating panel while the outer wall panel and the inner sound isolating panel are mounted with a heat and sound isolating air gap between them.
• the transversal supporting beams are connected to the horizontal steel frame through sound isolating brackets with sound isolating material and they hold to the frame due to their weight and friction while there is a heat and sound isolating air gap between the beams and roof panels.
• the method of a steel frame system construction consists of assembling and connecting horizontal and vertical elements, fastening wall, ceiling and floor panels, heat and sound isolation elements to the main frame.
• the main steel frame is assembled by connecting horizontal steel frames to steel columns while on the steel frame top there are fixed floor units using supporting side beams with sound isolating brackets, on the steel frame bottom there is mounted the ceiling panel using sound isolating brackets and with a heat and sound isolating air gap in between.
• all steel elements are connected with screws.
• the outer heat isolating wall panel is connected to the outer side of the steel frame.
• the inner sound isolating wall panel and the wall panel are connected through two L-brackets to the floor and ceiling panels creating a heat and sound isolating air gap between the outer and inner sound isolating wall panels. Then inner dividing walls are installed and the floor layer is covered with concrete.

• the new method of assembling three independent layers, i.e. the outer isolation wall panel (1), airborne sound isolating section (2a) and inner sound isolating wall panel (3) that are not in direct contact to each other, but only to the supporting frame and installation of inner walls allows to reduce work force costs by over 50% in comparison with currently used construction systems.
• the builder can save up to 50% of the construction time. Due to use of the method the builder can save up to 40% of the construction costs. Due to use of the method the builder can reach higher sound isolation values than those provided by conventional construction methods.

• the main construction parts are manufactured and tested under quality control in factory, which makes construction on site fast and precise.
