Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present invention claims priority under 35 United States Code, Section 119 on the U.S. Provisional Patent Application numbered 60/933,411 filed on Jun. 5, 2007, the disclosure of which is incorporated by reference.

FIELD OF THE INVENTION

The present invention relates to modular buildings, and more particularly, to structural elements for use in construction of the modular buildings.

BACKGROUND OF THE INVENTION

In present scenarios, the building construction field is generally labor and cost intensive. Construction of a building further requires involvement of a considerable amount of time. To reduce the factors such as labor, cost and time involvement in the construction of the building, prefabrication systems have been proven as one of the potential solutions. A typical prefabrication system involves prefabricated structures that are erected together to form a building structure.

Existing prefabrication systems fall into two major categories, namely, wood and aluminum frame prefabrication systems, and concrete prefabrication system. The wood and aluminum frame prefabrication systems are limited to low density suburban housing and where ground conditions are stable and dry. The wood and aluminum frame prefabrication systems are not suitable to those areas where the ground conditions are erosive and wet. The wood and aluminum frame prefabrication systems involve wood and aluminum frame structures and a foundation on which a building structure is formed by erecting the wood and the aluminum frame structures. The wood and aluminum frame structures and the foundation are generally light-weight. In case of the ground conditions being erosive and wet, light-weight foundation of such a building structure may not withstand and may result in collapsing of the building structure, thereby resulting in injuries to individuals living in the building structure. Further, the concrete prefabrication system is more appropriate for urban buildings due to fire and structural safety requirements.

These prefabrication systems have not been exploited to a great extent. More specifically, these prefabrication systems are exploited in commercial construction sectors of industry, but in case of residential construction sector of the industry, their use is very limited. Most of the prefabrication systems include structural systems such as, walls and floors, which do not solve architectural design needs of users. In addition to not being user or market oriented to any substantial degree, these prefabrication systems tend to be costly, require expensive erection and dismantling cost. Due to these reasons, such prefabrication systems have been unsuitable for applications in both commercial and residential construction sectors.

Apart from the above, building structures made by such prefabricated structures suffer from several disadvantages, such as cracking due to inclement weather conditions, which result into wear and tear to the building structures and often lead to leaks, creaks and structural damage. Further, inadequate and ineffective insulation to noise, heat and cold is one of the major problems in such building structures. Also, existing designs of such building structures are generally of a temporary nature and may not be easily customized to meet requirements of change in sizes and places of the building structures.

Furthermore, the portability of such prefabricated structures can be another problem because of their weight, complexity of structure and the danger of rupture of the prefabricated structures while transporting. The prefabricated structures are often required in areas where accommodation is needed in an emergency or on a temporary basis, such as in natural disasters areas, refugee camps and military bases. Oftentimes, such prefabricated structures need to be rapidly transported and erected to provide emergency habitable structures within a required time. Such prefabricated structures may not be easily and quickly erected to meet demands for such structures without a great deal of manpower, within the required time.

Accordingly, there is a need for prefabricated structures that can be used in dry as well as in wet and erosive ground conditions. Further, there is a need for all-purpose prefabricated structures that can be exploited by both the residential and commercial construction sectors of industry. Furthermore, there is a need for prefabricated structures that may be easily erected and dismantled. The prefabricated structures should also be reconfigurable to meet requirements of changes in size or place of a building structure, and should also meet requirements depending on need of long-term or permanent applications. The prefabricated structures should also be readily transportable. Moreover, the prefabricated structures should further be capable of withstanding poor weather conditions and of providing insulation to noise, heat and cold.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the prior art, the general purpose of the present invention is to provide prefabricated building structures such as a modular building system for configuring a building structure that is configured to include all advantages of the prior art, and to overcome the drawbacks inherent therein.

An object of the present invention is to provide a modular building system that may be utilized for constructing buildings for residential, commercial and emergency accommodation purposes, in areas such as, coastal areas, suburban housing areas and urban buildings areas. Further, the modular building system may be utilized to construct buildings independent of the nature of ground.

Another object of the present invention is to provide a modular building system that may be easily erected and dismantled, and may be customizable to meet changing requirements in size and needs of long-term or permanent applications of buildings, or places of the buildings.

Yet another object of the present invention is to provide a modular building system that may be able to withstand poor weather conditions and may provide insulation from noise, heat and cold.

Still another object of the present invention is to provide a modular building system that may be readily transportable.

To achieve the above objects, in an aspect of the present invention, a modular building system for configuring a building structure is provided. The modular building system comprises a foundation member, a plurality of wall members, a plurality of wall-retaining members and a roofing member. The foundation member has a plurality of engaging members. Further, each of the plurality of wall members has a plurality of complementary engaging members on a bottom portion and a plurality of engagement member on a top portion. The complementary engaging members enable the wall members to be detachably attached to the foundation member by engaging with the engaging members. The attachments of the wall members and the foundation member configure a space therebetween above the foundation member with a top opening. Furthermore, the plurality of wall-retaining members is adapted to be detachably attached with the plurality of wall members. Each of the plurality of wall-retaining members is detachably attached to the foundation member. More particularly, each of the plurality of wall-retaining members extends vertically from a top surface of the foundation member, and between at least two adjacent wall members of the plurality of wall members for configuring a detachable attachment therebetween.
