Production stages

Production process of timber framing houses
As the house is designed by the Plant architects, constructors approach the work, and being assisted by the HSB PC application, prepare drawings for production of house panels to accuracy of a single millimetre. These drawings are then transferred onto computers of production machines.



The Speed-Cut Center Hundegger SC2i processes timber bales (sawing at any angle), which are then milled, get the holes drilled, and being prepared for assembling of load carrying panel frame.



Assembling of load carrying frame is performed by the framing station of German Weinmann company, which arranges the frame elements automatically and nails them to accuracy of a single millimetre, keeping any angles, as originally designed.

Further part of the process is execution of the frame sheathing, facing the internal part of the building, which is performed by a computer controlled multi-function bridge of Weinmann company. The bridge slides over the load carrying frame, and the heads installed on the bridge, mount the OSB or plaster panels to load carrying frame with special staples, mill the timber elements and drill holes for boxes for electric installation and water and sewage systems.



A fully finished wall at one, upper side, comes out of the first multi-function bridge. This wall is then guided automatically onto the butterfly turning table, to which the other turning table approaches, afterwards the two tables are set in vertical position and then using “the pancake method”, the wall gets flipped over onto the other side, with the finished element facing down. The wall gets filled with non-flammable mineral wool and piping for installations assembled. The second multi-function bridge mounts the wall sheathing, facing the house elevation or other side of the partition wall. As the operation is completed on the second bridge, the wall panel is erected by the other turning table and is shifted for wall finishing line, where windows and doors are fitted, mineral plaster is laid or cladding is assembled.



Simultaneously, in the other house, floor panels with piping for water and sanitary installations are being produced. In the third house, roof production on the production line of the Swedish Randek company takes place, and includes special automatic saw for long timber bales processing, and the press with pressing capacity of 23 tons for joining the timber elements with steel nail plates.



In the fourth house, where a carpentry shop is located, stairs, cladding, panels and other wood assortment are produced. Production is operated by numerous carpentry machines, with one main device, being a computer controlled Carpenter processing centre Homag.

In the panel version, the production terminates at this point, and the ready wall, floor and roof panels are coupled on the construction site, making a house, which is then taken for the final processing phase (painting, floors, sanitary fixtures, etc.)

 

 
In the module version, production of modules takes place in the production house, where using an overhead crane, assembling of walls, floors and roofs into residential modules is performed. The modules are fully finished: painting, wallpapering, wall tiles, stones, wooden floors, lighting, sanitary fixtures, bathroom furniture, recess wardrobes, kitchen furniture with household equipment.
