K-typus kontra T-typus praefabrikata domus: Quid interest?

What is the difference between commonly used K-type and T-type prefab houses for construction projects?

Both K-type and T-type prefab houses are assembled light steel temporary buildings, widely used for temporary dormitories, offices, storage rooms and supporting site buildings.

Their main differences lie in six aspects:

structural system, module size, space capacity, appearance, overall cost and application scenarios.

Below is a clear comparison and respective advantages.

1. Differences in Structural System

Domus praefabricata K-typi

Adopts C-section steel frame following the K module system (1K ≈ 1.82 m) columns are exposed C-shaped steel. All components are connected by bolts, and wall panels are standard inserted sandwich panels.

Parts are highly standardized with strong interchangeability. It can be built up to tres aedificii gradus at maximum.

Praecepta Fundamentalia: Unified components, short production lead time, easy on-site assembly, excellent material compatibility, convenient replacement and maintenance of spare parts later.

T-type Prefab House (also known as T-type luxury prefab house)

Adopts square tube light steel frame with T-type insertion joint technology.

Columns are embedded and hidden inside walls with no exposed columns on the surface.

Connected by high-strength bolts, not strictly limited by fixed modules. Better structural integrity and airtightness.

Praecepta Fundamentalia: Smooth and beautiful appearance; higher structural rigidity, better waterproof and sound insulation performance than K-type; capable of larger span space and more flexible layout.

2. Magnitudo Moduli & Capacitas Spatii

Modulus Standardis

Typus K: Modulus fixus 1K ≈ 1,82 m. Latitudo et profunditas tantum combinari possunt in multiplicibus moduli, quod magnas restrictiones dispositionis inducit.

Typus T: Modulus principalis 1T = 950 mm; adinventio non-standardis permittitur absque restrictionibus obligatoriis modulorum fixorum.

Praestatio Intervalli

Typus K: Limitatur a specificatis ferri C-sectionis. Intervallum singulum non potest esse nimis magnum. Columnae internae sunt communes, spatium fragmentatum efficiens.

Typus T: Sustinet spatium amplum sine columnis, cum latiore visione interna, idoneum pro magnis officiis et atriis receptionis.

3. Comparatio Aspectus & Praestationis

Aspectus: Typus K habet columnas apertas, aspectum simplicem et planum; Typus T praebet superficiem parietis levem et integratam, similem aedificiis permanentibus, gradus altioris.

Impermeabilitas & Hermeticitas: K-typus habet plures iuncturas tabularum; T-typus meliorem technologiam sigillandi iuncturarum habet. Tectum potest esse cum canaliculis et solutionibus tectorum multi-pendulorum pro fortiori praestatione anti-percolationis.

Insulatio Sonora et Thermica: Cum eisdem tabulis parietalibus, T-typus meliorem totalem hermeticitatem habet.

4. Dux Selectionis

Scenaria Recommandata pro K-typo : Dormitoria operariorum, magazina temporaria, castra connexa in magnis aedificiis, projecta brevi duratione, angustae pecuniarum rationes, prioritas ad celerem distributionem.

Scenaria Recommandata pro T-typo : Sede projectuum, areae administrationis, centra receptionis, aulae exhibitionis, castra altae qualitatis, aedificia tempora ria longa duratione, areae exhibitionis pro externa imagine.
