Interlocking Structures wood-wool building boards

The topological interlocking is a principle whereby structural elements are arranged in such a way that no internal element can be pulled out of the structure without disturbing the neighbours, while separate blocks still can move independently within the geometric co nstraints. It is hypothesised that the main features of vibrations in such structures can be modelled by a system of coupled bilinear oscillators . oscillators with the springs having different stiffness in compression and tension. In a single bilinear oscillator this is known to lead to the emergence of multi-harmonic and sub-harmonic resonances. We investigate a system consisted of two
coupled bilinear oscillators and propose a method of determination resonance frequencies.We are engaged in providing our valued customers with an optimum quality range of Wood Wool Building Boards. In this product range, we offer Fire-Resistance-Rated Boards Slabs, Standard Wood Wool Structural Insulation Boards Slabs and High-Density Boards/Slabs, among others. Owing to quality features such as easy installation, durability and thermal & acoustic properties, these products are hugely demanded to be used in the construction industry.

Prefab Low Cost Housing Construction Permanent and detachable

Prefabricated building materials are used for buildings that are manufactured off site and shipped later to assemble at the final location. Some of the commonly used prefabricated building materials are aluminum, steel, wood, fiberglass and concrete. Prefabricated metal buildings use galvanized steel and galvalume as the chief materials for building. Galvalume is a form of steel coated with aluminum-zinc. This is to protect the building against corrosion, rust and fire. It also provides a sturdy and protective covering to the prefabricated building. Almost all the components of a metal building such as beams, frames, columns, walls and roofs, are made of steel. Most prefabricated military buildings use steel or aluminum frames. Synthetic materials are used for the walls and roofs. To provide enhanced security, a combination of both metal and cloth materials are used. Plastic flooring materials can be quickly assembled and are very durable. Prefabricated building materials used for small prefabricated buildings are steel, wood, fiberglass, plastic or aluminum materials. These materials are cheaper than regular brick and concrete buildings. Materials like steel, fiberglass, wood and aluminum are used as prefabricated building materials for sports buildings. These materials provide flexibility and are preferred for making structures and accessories like stands and seats for stadium and gyms. For making low cost houses, prefabricated materials like straw bale, Ferro cement, Calcium silicate products, composites and other cheap wood based materials are currently being used. Calcium silicate bricks are strong and durable. Ferro cement consists of a cement matrix reinforced with a mesh of closely-spaced iron rods or wires. In this type of construction

Delivery to Site and Storage: The units are delivered to site with appropriate accessories, the slabs must be stacked flat and protected from rain or" moisture. accidently if wetting does occur they must be allowed to dry. Breakage or distortion of the units may result owing to careless handling or incorrect stacking. Installation: The length of bearing ofa unit on to the structural steel section or a manufactured concrete must not be less than 50 mm (as per fig.) after making allowance for all movements of the structure. The grooved edge channels of the slabs are tongued with the help of a key-wedge to the adjacent units so as to give a flush joint and the units positioned so that the ends (which are secured to the supports with the fixings) come into contact. Screeds or roof finishes are then applied. Some care in handling on site is needed to protect units until laid, in-situ screeding shall be of a dry mix to avoid possible staining of the soffit, how-ever when - laying. wet-screed, temporary support must be incorporated to avoid difflection. Precaution: Slabs must not be used as a working area during construction, and crawl boards must be used to support the weight of wheel-barrows or similar concentrated loads. The units are capable of with standing normal pedestrian traffic likely to occur during construction work.
