[0004] FIELD OF INVENTION
[0005] Embodiments of the present disclosure relate to the field of structure and infrastructure assembly and more particularly a composite flooring structure with cross laminated timber and concrete topping and a method thereof.
[0006] BACKGROUND
[0007] As the demand for multi-story buildings continues to rise, so do the challenges associated with constructing durable, sustainable, and fire-resistant structures. A modern construction project requires a structure that not only provides superior strength and load distribution but also meets high environmental standards. The traditional construction methods, particularly those that combine timber and concrete, often face difficulties in achieving an optimal balance of durability, flexibility, and load-bearing capacity. The integration of these materials must be carefully designed to meet both performance and sustainability expectations, and conventional approaches frequently fall short in addressing these complex needs.Traditionally, multi-story construction predominantly relies on the use of steel and reinforced concrete, which has been the backbone of high-rise buildings for many decades. These materials provide robust structural support, with steel offering flexibility and concrete delivering high compressive strength. A building framework is typically constructed using reinforced concrete slabs, beams, and columns, which are cast in place or prefabricated and then assembled on-site. This method has been proven to be reliable, offering strong load-bearing capacity, stability, and durability. In addition, the use of brick and block masonry for nonload bearing walls remains a common practice in some regions, providing further stability and insulation. These established methods have supported the growth of cities and are still widely used in the construction of multi-story buildings due to their ability to withstand various environmental stresses. Additionally, the existing methods in construction including single-story and multi-story construction frequently relies on traditional concrete and timber structure, but these structures present several limitations, particularly when combined.
[0008] Although there is notable progress in integrating technology into structure and infrastructure assembly , however, these existing methods are often limited by several factors. The challenge of achieving a strong, flexible, and cohesive bond between wood and concrete is compounded by the need for enhanced fire resistance and load distribution across floors. The structural beams in conventional designs are often prone to stress concentrations that reduce the overall integrity of the structure, especially when subjected to dynamic loads including a wind or a seismic activity. Additionally, the inherent differences in the material properties of timber and concrete make their integration in structural applications challenging and less effective in achieving both performance and sustainability goals.
[0009] In response to these challenges, there exists a need to address these challenges and provide an innovative construction structure that enhance the integration ofmaterials for improved performance. A more effective approach would involve the development of composite structure that combine the strengths of different materials, such as timber and concrete, while ensuring superior load distribution, stability, and adaptability under various dynamic conditions. These structures should also align with sustainable construction standards, providing environmental benefits alongside enhanced durability and fire resistance. The ongoing evolution of building technology offers opportunities to create more resilient, efficient, and sustainable solutions, ensuring that multi-story buildings can meet the demands of the future.
[0010] Hence, there is a need for an improved a composite flooring structure with cross laminated timber and concrete topping and a method thereof which addresses the aforementioned issue(s).
[0011] OBJECTIVES OF THE INVENTION
[0012] The primary objective of this invention is to introduce a composite flooring structure designed to enhance the structural performance, fire resistance, and sustainability of multi-story and high-rise buildings. By combining a crosslaminated timber slab bands with an engineered structural beam, the structure offers a lightweight, high-strength solution that optimizes load-bearing capacity while reducing the weight placed on building foundations. This innovation also ensures efficient load distribution and minimizes stress concentrations through the incorporation of top and bottom flanges in the structural beam, which supports compressive and tensile forces, respectively.
[0013] Another objective of the invention is that the structure is adapted to enhances fire resistance and durability. A 50mm high-performance concrete topping is applied over the cross-laminated timber slab bands, acting as a protective barrier that insulates underlying components and maintains structural integrity during high-temperature events. The use of a specialized grout layer between the cross-laminated timber slab bands and concrete ensures effective bonding, preventing delamination and promoting long-term stability. The structure also streamlines onsite assembly by incorporating prefabricated components, reducing construction time, labour, and machinery requirements.
[0014] Yet another objective of the invention is to provide a composite structure that provides flexibility, seismic resilience, and energy efficiency in a building design. A web opening within the structural beam allow for the integration of building utilities including plumbing and electrical wiring without compromising structural strength. The composite structure also improves seismic durability by absorbing and dissipating energy, making it ideal for regions prone to earthquakes. Additionally, the cross-laminated timber slab bands material enhances thermal and acoustic insulation, while the use of renewable cross-laminated timber promotes sustainable building practices by lowering the carbon footprint of multi-story constructions.
