What are the fire protection requirements of construction materials according to Council Directive 89/106/EEC? The Construction works must be designed and built in such a way that in the event Of an outbreak of fire: · the load-bearing capacity of the construction can be Assumed for a specific period of time; · the generation and spread of fire and Smoke within the works are limited; · the spread of fire to neighbouring Construction works is limited; ·occupants can leave the works or be rescued by Other means; ·the safety of rescue teams is taken into consideration. ·The Classification or availability of the structures should be considered based on The fire protection levels, and using data from reaction to fire tests. (MSZ EN 1364 1-6 series: Fire resistance tests for construction elements) What Characteristics is the fire classification based on in EN 13501-1? Give the Classes to each! ·The classes is EN 13501-1 actively consider the parameters Like characteristics of flame spread, extend to include the rate of heat Release, heat release, toxicity of smoke density and combustion result Etc..  ·EN 13501-1 also provides a number Of test methods not only considering the actual fire scene, but also Considering the end use of the material, which is more practical Representation.

Dry constructions What does "dry" Construction mean? What type of constructions, materials and technologies belong To "dry" constructions? · Minimal use of water „dry” construction Systems ·Prefabricated elements ->assembly on site Finishing works: 1Assembled partitions 2Suspended ceilings 3 Raised Floor systems 4 Dry screeds, dry linings. But Also  Prefabricated elements of  loadbearing structures ·Materials ·Timber ·Metal (steel) ·Precast reinforced concrete ·Technologies ·(Traditional technology) ·On-site assembly – small Elements · On-site assembly – panels ·Log houses ·Construction systems · „Light” construction: weight of outer walls Is less than 300kg/m2 What are the characteristics of metal frames? Material is Cold formed or hot rolled galvanised steel ((C studs, I beams, U beams etc. )) ·The Frame is cut and packed in a factory ·The package is transported to the site ·The Frame is assembled on a previously completed foundation/basement connections Are made with screws · Installing insulation, covering, wires pipes, doors and Windows etc.  Introduce the technologies Of timber frames (types of technology and steps of construction)!  ·Technology: · Low level prefabrication – elements cut and labelled in factory; · Mid-level Prefabrication – wall-, roof-, slab panels are produced: frame and lining; · High level prefabrication – wall-, roof-, slab panels are ready-made in Factory, with coverings, claddings, doors and windows, wires, etc. ·On-site Assembly – speed, demand on equipment depends on the level of prefabrication · Technology steps: 1. Choosing the Preferred house style from  Catalogues  2. A fixed price quote With a guaranteed  completion date is Given 3. Selecting finishes, fixtures and fittings  4. The wall and roof panels for the house, Pre-fitted with doors, windows, service ducts, sockets and insulation, are Precision-engineered in the factory  5. The panels arrive on site by truck, the team of skilled tradesmen start to Work  6. The house is roofed and watertight Within four days  7. The house is ready In 8-12 weeks What is the difference between solid wooden panel and log house? Solid wood panels: cross laminated Timber · Walls and slabs are prefabricated ·Assembly on site ·Complementary Layers: heat insulation, rendering,  Internal covering · Measures: thickness: 94-500 mm,  height: max. 2950 mm, · Lenght: max. 16500 Mm. Log houses: ·Prefabrication: Beams ·Each beam is numbered and  the Position is indicated. Construction: ·The first row of beams is laid out on the basement ceiling/floor slab and Measured with precision.  ·Following on From this, the log beams are laid out in the same sequence as their numbering. What Are the supposed advantages/disadvantages of dry constructions - what is true About it? ·Supposed advantages: ·Full Service (design, build, finance); · Fixed prices; · Fast construction; · Guaranteed quality; · Low energy consumption… · Supposed disadvantages: · Lifespan; ·Safety (storm, burglary, Fire …); · No thermal mass… · It depends on the chosen technology and the Contractor! Facts in case of approved Product and qualified contractor: · The construction time can be planned – Prefabrication is independent from local conditions. On-site activities: mainly Assembly. ·Well-planned building. · Very precise construction. · Improving Regulation. What are the problem sources of dry construction systems? (How to Avoid them?) ·Problems with the planning – using a system ·Different regulation At the production and the construction ·Self-made realisation ·Foundation/basement Is usually made by a different contractor · Fast construction · lots of trader, Workers at the same time ·Quality of the assembly · Coordination and control of The processes · Quality of the materials (panels!) · Transportation and storing ·Use (maintenance, fixing on the walls, etc.)
