Innovative Modular Pad Footing System will be used in our proposed house. The purpose of pad footing is to transfer the loading of building to the soil or ground beneath it. Timber formwork system has long been used in the construction industry. Due to the wastage of timber used and the impact to the environment, cold-formed steel section formwork is introduced. The present invention attempts to reduce wastage caused by the excessive use of wooden formwork in the conventional construction method. This is done by providing a permanent formwork system that forms the outer panel which suits the design requirements for any typical pad footing foundation.
The cold-formed steel section which is meant to replace the reinforcement bars should be able to withstand the intensive reaction forces from the ground that could cause shearing or flexural failure on the pad footing. This invention is suitable to be used as the prefabricated component that can be developed in the standardized design tables and can be mass produced. The modular construction system is adopted with all components completely prefabricated off site. The main advantages of using prefabricated components includes the possibility to speed up the erection of the panels, and to also achieve better quality control in production, as well as reducing on-site labour. Modular construction is most cost-effective where large production runs are possible for the same basic configuration of a modular component. With the proposed construction technology, the construction materials are packed up in transportable containers, delivered to site, unloaded as ready assembled panels, and can be installed in a short time.
Light gauge cold-formed steel members (generally referred to as light steel sections) are used as the primary load-bearing elements in the light gauge steel frame. These sections are prefabricated off-site to form wall panels, floor cassettes, and volumetric modular units such that they can be installed rapidly on site which reduces local disruption. The ground beams are connected to the column stump using anchoring bolts and base plate.
