ABSTRACT OF THE INVENTION (to be given along with complete specification on separate page) "A BUILDING PANEL & BUILDING STRUCTURE MADE THEREOF" Field of Invention The present invention relates to the building panels for construction industry so as to replace conventional building material such as bricks, etc. Further it relates to the building structure made of such panels. Prior Art: Currently the construction industry uses brick, siporex blocks, and concrete walls as both internal and external walls. These conventional materials are heavy items, require huge cost of transportation, storage at site and are built piece by piece, by means of joining material such as cement mortar, making it extremely time consuming & require a lot of labour, both skilled and unskilled. To do erection at site, with all the above factors taken into account, is costly also. Moreover, conventional brick is made from clay, which is not easily available near big cities. Its also not environmental friendly material, since it destroys the good quality land mass and does not provide any other added benefit except protecting the house from external weather condition. Today in our cities most of the space, where people work or stay, has control weather. Conventional brick wall does not offer much of a resistance to heat and cold. Further in case of earthquake, the fatality increase because of brick and mortar derbies that falls on human being. Since these materials having sufficient weight, they can hurt or bury anyone that may come under it. 1 With rapid industrialization and consequent urbanization in our country, there is a massive requirement of constructed house for commercial and residential purposes. This growth is not only in big cities but also in mid-sized and small towns too. Since land is always in short supply, the construction is mainly high-rise buildings, which evident from changing skyline of any of our cities in India. In the last 5 to 6 years, we all have been experiencing this change. In fact, the future projection of growth of our urban centers is mind boggling. Projection is that more than 50% of our population will be in urban set up by 2025. This will require a massive construction activity in years to come and time, coupled with quality of construction, will be most important factor in meeting such requirements. Hence in order to avoid the disadvantages associated with conventional construction material and to achieve the above mentioned goals, there is need of a new construction material which will take care of all aforementioned problems associated with the conventional construction material. Object of the Invention: The main object of the present invention is to provide a new construction material which overcomes the above said drawbacks associated with present construction materials and methods. Another object of the present invention is to provide a building panel being used in construction industry which is light weight. Yet another object of the present invention is to provide a building panel which is economical and reduces the overall construction cost. 2 Yet another object of the present invention is to provide a building panel which is easy to install with minimum labour and does not require any special skill for installation. Yet another object of the present invention is to provide a building panel which provides excellent protection from the external weather. The weather conditions include hot, cold, tropical, etc. Yet another object of the present invention is to provide a building panel which is environmentally friendly. Yet another object of the present invention is to provide a building panel which is easy to store and transport. Statement of the Invention: Accordingly, in order to achieve the above mentioned objects, that is, provided a building panel, which comprises: A pair of wire mesh, each wire mesh is made by welding plurality of vertical and cross members of the wire; An expanded polystyrene (Thermocole) core being sandwiched between the said wire meshes; and connecting wires to connect said wire meshes; Wherein the connecting wire is pierced completely through polystyrene core at offset angles for providing better strength and welded to each of the outer layer of side surfaces of said wire meshes to form a building panel. According to another embodiment of the invention each wire mesh can be either rectangular shaped, squared shaped or L shaped. Also connecting wires are welded to the wire meshes in zig-zag manner. 3 Also there is provided a building structure which comprises: plurality of building panels as discussed above connected to, each other; connecting means of connecting said building panels with each other; and torr steel bar being grouted and fixed at the footing of said building structure through said building panel for increasing the load bearing capacity of said building panel. In such building structure the connecting means comprises a joining wire mesh which is connected to adjacent building panels by means of connecting wires and torr steel bar passes through wire mesh on inner side of the panel and tied it with connecting wires. Brief Description of the Drawings: Fig 1: Shows the prospective view of a building panel in accordance to present invention. Fig 2: Shows the sectional cross view of the panel indicating exact location of welding joints between (Zig-zag) wires & mesh. Fig 3: Shows sectional cross view of the constructional panel with both sides plastered finish. Fig 4: Shows front view of the erected panel with joining mesh between panels and vertical tie bar (anchoring bar) fixed with the panels. 4 Fig 5: Shows the re-inforcement between ceiling and wall panel and / or Corner Wall Panels, joint both outside and inside (L shaped mesh) Fig 6: Shows door & window openings in the Panels, with re-inforcement. Detailed description of the Invention- The above and the other objects, features and advantages of invention will become apparent from following description read in conjunction with the accompanying drawings. Now referring to Figure 1, The expanded polystyrene building panel (1) in accordance to present invention comprises Front & back wire mesh (2, 3) made by welding vertical (6) and cross member (7) of the wires, together forming a mesh of required mesh size, such as 2" x 2", 3" x 2", 4" x 2" or any other Mesh size, depending upon the requirement of strength of the panel. These wire meshes (2, 3) will hold the Expanded Polystyrene Core (4) of required thickness. The thickness will depend on final wall thickness required, which again depends on building design. Front & back wire meshes (2, 3) are joined through core (4) by a connecting (Zigzag) wires (5), welded on both sides. The welding joints (8) give it enough strength to make both wire mesh (2, 3) to stand alone. The joining of mesh also helps in balancing the load in case of difference in thickness of cementing, both externally & internally. The wire mesh (2, 3) fabricated and fitted on both sides gives the reinforcement to cementing. The flexibility of the diameter of the wires and mesh size, which depends on the load requirement, give the strength to the structure. In fact, one can design and insert the conventional re-inforcement also since core can be easily cut to suit the purpose. These panels remove the drawback 5 of currently used material for the purpose. Each panel has sizes of 4' x 10' or 4' x 8' or 4' x 7.5' or any such large dimension compare to single brick of few inches dimension. Thereby, if one panel is erected; this can be done in few minutes, compared to few days of brick work. Advantages of choosing the most light weight core is it makes the panel very light (for example, a 40 sq-ft. panel weighs less than 20 Kgs., which is hardly less than 5% of the brick wall of that size) this light weight of panel makes its handling very easy. In building site, the transportation of materials is a major issue. It requires manpower, heavy weight lifting devices & plenty of time. All these drawbacks are eliminated by the building panel of the present invention. One person can easily lift the panel and put it in position for fixing. Also the polystyrene core does not allow heat to pass through, keeping the room inside cool as compared to the outside heat. Expanded polystyrene is one of the best know thermal insulation materials. It also does not allow the sound to pass through, thereby cutting the noise from outside or from one room to another, and avoiding noise pollution, especially in big cities. Expanded Polystyrene (Thermocole) as a core material in the panel makes it light in weight, and acts as insulation of heat and sound from outside to inside and vice versa. In hot weather, the outside heat infiltration will be absolutely minimum, thereby not only reduced temperature inside but reduced load on the air conditioning system also, helping the saving of electricity to run such unit. Modern building code recently announced by central government is emphasizing the need of saving of electricity in the house, since we have huge shortage of electric power, which is going to last for another 20 to 25 years. Government has announced that these codes, restricting power uses, will be shortly made into law, making it mandatory. This purpose is served by using polystyrene core as one of the material in the building panel. 6 The panels of the present invention after finishing will be 5% of the weight of conventional material (4'x10' panel weighs less than 20 Kgs.) and its monolithic nature of construction make it the most earthquake resistant material available to building industry. Since panels are light in weight, the design of load bearing structure such as beams and pillars, which carries theses weights to the footing, will be less heavy, thereby reducing the overall cost. Expanded polystyrene core of the panel does not allow moisture to pass through thereby keeping the seepage, if any, limited to a particular area only where it occurs. An erection of these panels is very simple and less laborious. Now referring to figure 2, the sectional view of the panel (1) is shown. It gives the exact location of the each component of the panel (1). This view shows the exact welding point (8) of joining wires (5) and both sides wire-mesh (2, 3). The wire (5) pierced completely through core at offset angle. Now referring to figure 3, the sectional view of the finished panel with both side plastered (9) or concrete finish as per need. These finishes, though shown as sand cement plaster, could also be of any other finish, such as gypsum or epoxy cement or other finishing material required by the customer. The wire mesh (2, 3) and slots in the wire mesh, provides reinforcement to sand cement plaster. After the plastering or concreting the strength of the wall becomes far superior to the conventional wall of brick or similar structure. This superior strength bears extra load of wall hangings, shelves or any other load that the wall may be subjected to. The thickness of plaster could be 1" or 172" or 2" or any thickness, depending on the requirement. The external surface may have higher thickness of plaster than the internal side of the walls. Now referring to figure 4, which shows the joining of each panel (12, 13, 14) and fixing of each panel (12, 13, 14) with the building structure (11). The joining of panels (12, 13, 14) is done with same type of wire mesh (15, 16), which is used in main panel (1). The joining mesh (15, 16) is tied with the original mesh by 7 means of binding wires. This joining process is very simple and quick. These panels get amalgamated with building structure very easily. At the footing, 12mm to 16mm diameter torr steel bars (17, 18) are grouted either at the time of casting or after wards by drilling holes and fixing it with epoxy cement. These bars (17, 18) pass through the wire mesh on the inner side of the panel and tied with binding wires. The load of the cementing is entirely on the reinforcement mesh, which again is tied with footing of the building through the tie bars (17, 18). Core does not hold any load, as in case of any conventional structure, thereby avoiding the limitation, as far as load is concerned of the core (4). Now referring to figure 5, which shows the reinforcement by "L" mesh (21) on corner of the walls and or walls and ceilings. These "L" mesh are tied by binding wires. In these methods of joining the panels, after erection and before plastering, the whole surface will resemble as one monolithic structure without any separate joint. In fact, because of reinforcement, joints will have superior strength, since extra wire mesh will give extra reinforcement. Now referring to figure 6, which shows the door and window opening (31) in the panels, with re-inforcement. It shows doors (32) and windows (33) that need to be provided in any building. These doors (32) and windows (33) can be provided either before fixing, if the exact position is known, or after erection of the panels, by cutting the wire mesh with bolt cutter and removing the expanded polystyrene core by propane torch or a hot air gun or any cutting blade or equipment. The door (32) and window (33) opening need to be reinforced with corner flat mesh (34, 35, 36, 37, 38, 39) to take extra load. Any kind of extra reinforcement, if required, depending on the load of particular area of the building, can easily imparted by just removing that much portion of the polystyrene core (4) and inserting the reinforcement bars. 8 Advantages of the building panel of the present invention: 1. It saves time as it provides fast as well as high quality construction. It is more than 50% faster than standard construction and hence provides speedy occupancy. 2. It reduces the need for heavy equipment and requires fewer labourers on job site. Hence saves money during construction. 3. it enhances resale and market value of the building structure. 4. It provides strength, durability and greater structure integrity to the structure which makes the structures maintenance free. 5. It ensures safety and security and excellent performance in seismic zones (earthquake resistance). 6. It provides excellent wind protection. 7. It is insect, termite, rodent resistant mold, mildew and fungi resistant. 8. It is environmentally intelligent. 9. It is excellent thermal and sound barrier. 9 Industrial Applicability: The building panel of the present invention is used for numerous building applications residential, commercial, industrial and institutional; and is designed to meet standard building code requirements. It may be used in place of wood framed walls, metal framed walls, and masonry block walls or in place of pre cast panels. It may also be used for floor systems, ceilings and to provide a roof structure.
