Product    Description

GENERAL INFO

All prefabricated modular type buildings are constructed on the reinforced concrete foundations. After completion of the erection of all external – internal walls, roof and suspended ceiling; leveling concrete (screed) must be prepared to install floor covering materials.

Foundation and leveling works should be prepared by the client.

STEEL STURCTURE   

Foundation: Design of concrete foundation with steel re-enforcement will be provide by HEYA.

Details of Steel Structure: Connected using galvanized bolts and nuts.

Design Loads:

Floor load: 250 kg/m²

Roof load: 100 kg/m²

Wind load: 50 kg/m²

Earthquake Resistance – Level 8

Specification of Steel Works:

1.    Material: Cold-rolled steel profile with hot dipped galvanized finishes

2.    Manufacture of joint plate: Using steel plate welded. Hot-dip galvanized after adjustment.

3.    Column connection: Using M12 to connect column with joint plates.

4.    Roof beam connection: Using M12 high tensile bolt and nut to connect roof beam and joint plates.

5.    Bracing: Bracing made with thread tapping and hot-dipped galvanizing finishes.

6.    Main elements and typical connection details:

WALL AND ROOF PANEL

Exterior Walls     : Prefabricated sandwich panel made up from pre-colored galvanized steel plate of 0.5 mm. in thickness at inner/outer face and EPS (R Value 33.30) insulation of 100mm in thickness and 12kg/m3 in density. Wall frame will be constructed of steel profiles.

Interior Walls    : Prefabricated sandwich panel made up from pre-colored galvanized steel plate of 0.5 mm. in thickness at inner/outer face and EPS (R Value 33.30) insulation of 75mm in thickness and 12kg/m3 in density. Wall frame will be constructed of steel profiles.

Polystyrene foam sandwiched panel constructed by 2 layers of pre-painted steel plate and high density polystyrene foam jointed by strong adhesive, under high compressed process to form solid panel.

EXTERNAL COATING (Optional Item)

Specification of Texture Coating (Grey stone appearance):

Elastic exterior coating is flexible coating used to help protect and maintain the appearance of exterior masonry walls. It is designed to bridge existing and future cracks in masonry by stretching and shrinking as exterior walls expand and contract with changes in temperature. Use of elastic exterior coating is an excellent way to help prevent wind driven rain, acid rain and freeze-thaw conditions from damaging a building’s appearance and structural integrity.

Application Reference:

a) Surface preparation: Previously unpainted surface clean of dust, grease and loose matter. Remove unstable old film by high pressure wash or scraper. The substrate should be clean, dry and stable, ensure the surface moisture < 10%,PH<9.5.

b) Primer: sealer. Theoretical spreading rate: 6-8m2 /kg.

c) Finish: Stir well before use, brush 1-2 elastic coating. Theoretical spreading rate: 1-1.5m2 /kg (two coats). Interval: ≥6h. The temperature of application environment and substrate should ≥5^oC.
