CHAPTER 2

• Panel system – Defined as prefabricated exhibit composed of connected rectangular panels of various sizes • Made in various forms and normally prefabricated at factory • Those structures contribute only for aesthetical expression of

building

Building system classification according to relative weight of component (Majzub, 1977).

Introduction

General system System Production Material

Panel System Light and medium weight panel

Wood frame, metal frame, and composite materials

Heavy weight panel (factory produced)

Concrete

Heavy weight panel (tilt up – produced on site)

Concrete

• High quality with respect to strength, durability, shape and surface finishing

• Used for precast facades of building, which are intended to contribute to the esthetical expression of the construction

Creativity Precast Concrete

• The face or front of a building, especially the principal face.

• A facade is the outer appearance which is forecasted to make the viewers or observers believe that the thing behind the outer appearance will be as good as the outer appearance

PANEL WITH CAST-IN ALUMINIUM WINDOW FRAME

• The implementation of cast-in window system requires coordination between the window fabricator and the precaster

• Proper handling and protection are important throughout the precast process, delivery and erection of the precast wall panels.

• Protection of the frames should remain intact throughout the construction phase to avoid physical damages to the frames, which could be costly to rectify or replace.

CORNICE • Cornices are generally found at the very top of an exterior wall,

just under the roof line.

• Historically cornices were designed to prevent rainwater from running off the roof and hitting the walls

• Most buildings today solve the rainwater problem with gutters, however cornices are still used as decorative elements.

• Position of cornice:

a) the upper slanting part of an entablature located above the frieze

b) over a door or window

c) around the edge of a pedestal

PRECAST STAIRCASE

• The stair units are precast reinforced concrete modular stairs used in layouts which are individually designed to suit the client's requirements

• The Precast Staircase - manufactured in sections specifically designed to be manhandled.

• The Precast Staircase System - suited to all types of buildings, including residential, commercial and industrial applications, e.g. townhouses, clusters, offices, houses, low-cost housing and fire escapes.

ADVANTAGES OF PRECAST STAIRCASE

• Expert advice, professional service and prompt delivery

• Quality, uniform product - all dimensions are constant throughout the stair making tiling / finishing simple

• Flexibility - fully adjustable to suit any floor to floor height

• The advantages of a dry trade

• The elimination of form work enables instant access and use of stairs

• Tiles laid directly onto stairs - no screed required

• Balustrades can be fixed to either the top or side of the stairs

• Rapid installation

• Cost savings on material, time and labour

PRECAST STAIRCASE

Example of product

• A Structural Insulated Panel (SIP) is a panel construction system consisting of Foam-Control® EPS (expanded polystyrene) insulation laminated between sheets of structural sheathing.

• This simple sandwich panel forms an amazingly strong insulated panel for building walls, roofs and floors for sip homes or commercial buildings.
