partition wallsfunction, features, and grouping of partitions
features: ● self-supporting, non-load-bearing● thin and vibration-sensitive● load to slab● doors, lintels, piping, mechanical and electrical wiring are integrated
partition walls
role (function): internal space division and space separationspace separation: visual, acoustic + mechanical stress special: flat separating wall: Party wall (20 cm RC, 30 cm limestone or more solid ceramic)
requirements: strength, stiffness, acoustics,- water- and moisture-resistance, formability, possibility of mounting, fixability, load capacity, holding plaster layer
● strength: taking loads from usage - sharp and blunt bumps, even load (30kp/m2), slamming doors ● stiffness: ensuring rigidity even in case of non-displacement-free installation
(only place + wedge) and perforation (doors, mechanical installation)
water and humidity tolerance: to resist water and moisture permanently● rooms on both sides of the space should be of approx. the same
relative humidity (vapor migration, warping can be=l/600)● sanitary rooms: wall insulation or installation of watertight cladding
acoustic: meet the requirements of air-borne sound insulation (RW depending on the function of separated rooms)
● acoustically: single-leaf, double-leaf● enclosure structure should be heavy but flexible● only few sound bridges allowed (flanking transmission: slab and wall
shape and size tolerance:degree of length, width, thickness and angle deviation, edge curvature,
plane curvature should comply with the specificationsholding plaster finish:
frequent vibrations from use → only partition with suitable surface roughness (corrugation) can hold plaster
formability (cutting), fixability
● allow the reception of additional structures (socket, plinths, switches, plug sockets, lighting fixtures, etc.)
● reception of furniture and equipment of use (shelves, pictures), without damaging deformation● reception of mechanical equipment and wiring of the intended purpose
traditional mounting panel
requirements 3partition walls - overview
it is forbidden to integrate wire into the wall of residential and office premises designed for human habitation (even from the other side)!
groupings of floors (their load-bearing structures) by● material● technology● structural design● static scheme● reinforcement● position within the building
requirements for floors : strength, sound insulation, thermal insulation, waterproofing (precipitation or sanitary water), fire resistance, special requirements, possibility of wire installation
multiple-support - for multi-span roofs → smaller moment, deflection andcrackfor monolithic floors easy to solve, for prefabricated slabs can be solved only with additional structures
durability requirements: - physical wear (should be a durable structure)- moral wear (consistency of structure, function and modernity, obsolescence)
waterproofing requirements:- always needed for roof floors (precipitation effect)- for intermediate floors: in case of group shower, or special technology- for balconies: protection of built-in layers (frost damages) and bottom surface
(plastering)
multiple-supporting, durability, water-proofingrequirements for floors 5
goal: maintaining the building's stability for a specified period of time, limiting the spread of fire, serving the safety of escape and rescue
classification methods: ● fire class (reaction-to-fire) – description of the fire behavior of a building material or
a construction product (flammability - how difficult it is to ignite, rate of smoke development, burning dripping)A1, A2 B, C, D, E (F) s1, s2, s3 d0, d1, d2
● fire resistance limit – duration for which a building structure withstands the fire impact (R, E, I performance features + duration in minute – 15…240 minutes)
load-bearing capacity in case of fire
preservation of integrity (burning through)
thermal insulation capacity in case of fire
fire protection features of construction productswalls – requirements for walls – fire protection 2
fire protection requirements for floors
classification:● intermediate floor (general)● basement floor (increased requirement)● fire-retardant slab (around fire compartment)● roof support structure (bar-like elements (beam) - not space separation)● space separating structure of roof slab (structures of surface weight below 60
kg/m2 - sandwich panels, layers constructed on corrugated steel sheet)
