INSULATING LIGHT WALL BUILDING ELEMENTS

Description

This invention concerns new perspectives on construction element that has high insulation properties to be produced according to construction standards and measures for the building of internal and external walls and the Asmolen ceiling applications.

In order to construct the internal and external walls, in today's buildings, brick made of clay, cement based briquette made of light or heavy aggregate (sand-stone-BIMS-particular straphor), asmolen or block material made of asmolen or gas and foam concrete and concrete made of light aggregate with pores are used. The Standard Numbers of the Turkish Standards Institute (TSE) and the unit volume weight are given in TABLE 1 as documents and sources of the current technology.

The individual use of each above materials as construction elements for wall building causes some technical and/or financial problems. The technical and other problems to be solved by the use of this invention are as follows:

1—Low insulation feature,

2—Formation of heat bridge at the joints owing to the mortar,

3—Requires additional insulation for the reasons cited in paragraphs 1 and 2, and will increase heating and cooling expenses if additional insulation is not performed,

4—Because of their heavy weight they add additional burdens to the building and pose threat to life safety, and cause cracks in the walls as the building settles or shakes,

5—The internal and external surfaces do not hold plaster well and easily and/or requires a rough plaster,

6—Long and costly labor, such as (wall construction, insulation, application of rough plaster), higher construction material costs (amount of concrete, amount of equipment, insulation material, amount of rough plaster),

The heat insulation coefficients of the construction materials available in the market are given in TABLE 2.

The product standards of the primary insulation materials used in heat insulation are given in TABLE 3.

The known construction materials (bricks, briquette, asmolen gas concrete) have densities between 400-2200 mg/m3 (TABLE 1). While this material density brings significant loads to the bearing system of the building, its coefficient of insulation, in accordance with TS 825 Heat Insulation regulations, which is gaining more and more importance in Turkey, is extremely insufficient as it can be seen in TABLE 2. Two important reasons for lack of insulation are as follows:

1—The cement based mortar at the joints after the construction causes a heat bridge. 2—The second thing is the different ratios of materials and common techniques in the process of the product cause low insulation features. In order to prevent this situation you need to apply additional insulation for heat-sound-water insulation at added labor material costs. If you avoid performing the additional insulation you tend to incur much bigger expenses in the long run because of the loss of heat.

According to TS 825 of the Turkish Standards and norm number 4108 of the German DIN, insulation materials such as stonewool, extruded polystyrene, expanded polystyrene, glass wool, polyethylene, polyurethane, glass foam whose insulation values are less than (λ) 0.060 kcal/mh° C. are called “heat insulation materials” and those with higher values are called “construction materials”.

In order for the heat insulation materials to achieve the desired performance, their vacuum ratios have to be high, their densities low and their ratio of humidity have to be low. Construction materials manufactured with only heat insulation do not achieve the desired results. In addition to heat insulation, the importance of humidity flow and condensation are other features that are sought in insulation materials as well. If the material has a high steam diffusion resistance factor this reduces the effect of the steam, and is less affected by the changes in heat and the density has to be high in order to store the heat and the heating temperature is expected to be high also. It seems not possible for one single material to possess this and every unit does not have similar features in itself.

The most important task is performed by the external construction components in protecting the buildings from the effects of heat/cold. Walls and windows being the primary, the ceiling, chimney, and the components that come into contact with the ground/floor protect the building from the external effects. The heat insulation, heat storage and heating-cooling features of the materials that constitute these components, in respect to heat insulation, are very important.

When used properly, heat insulators are the kind of materials or composition of materials which convey, transfer and/or which reduce the passing of energy with the type of heat rays. These insulation materials could be made of fiber, granules, film layers, either in blocks or single parts, with open-closed cells, connected to each other either chemically—mechanically or supported with mixed materials.

Taking into account the facts given above and according to the best known technology, a new insulator light wall construction material has been designed by combining a construction material with superior properties with an insulator which provides superior insulation to be used instead of the various construction materials which provide poor insulation and which do not reduce the cost when used individually. The superiority of the material in comparison to other similar products are listed below.

1—The weight of the new product is between 250-350 kg/m³ while the weight of the other products varies between 400-2200 kg/m³.

The 1 m³ or 1 m² weight of the product is at a minimum 20% lighter than 1 m³ or m² of gas concrete known and accepted actually as the lightest wall construction material and is 260% lighter than the other materials. Thus, the load of the building is decreased at these ratios as well. The reduction in the load of the building has to bear will also decrease the quantities of concrete and filling equipment used in the bearing system and as a result the total weight of the building will also be reduced. This deduction means that significant savings may be achieved in the total cost of the building.

2—The reduction in the unit weight will contribute to work health and safety because it will facilitate the carrying of the material and construction of the wall and by reducing the load of the building and the wall system it will provide safety to a great degree in the case of earthquakes.

3—Since the new construction material is light and flexible it will prevent cracks in the walls as the building settles in its foundation or as it shakes.

4—It will achieve high standard heat, sound and water insulation in the walls of the buildings. This will preclude additional insulation process, additional labor and additional cost.

5—The product, with its horizontal and vertical axis will reduce the cost of labor, insulation costs, and heating and cooling by preventing heat loss at a maximum.

6—It will reduce production and transportation costs because it is much lighter than the other products of the same volume.

The wall construction elements have been shaped in the manner given in the enclosed figure for the invention to achieve its intended purpose and of these;

The explanations of the figures have been numbered and their corresponding explanations are as follows:

1—Polystyrene or polyurethane external unit

2—The thickness of the external unit

3—The bottom surface of the external unit

The external of the product (1), shall be manufactured with (Expanded, Extruced Polystren Stropor) or one of the polyuretahne foam tight materials in appropriate different sizes (FIG. 1). The thickness (2) of the external unit shall be between 1 and 5 cm. If EPS is used in the external unit (1) then the known procedures shall be applied; the granular raw materials shall be expanded beforehand with steam and shall be in one of the settling silos for the product to settle. Later, the material treated beforehand shall be injected and compacted into forms and shall be placed in the oven after it reaches a certain degree and removed from the forms once the product takes the final shape. If polyurethane foam is used in the production of external unit (1) two or more chemical liquids shall be mixed together in specific ratios. This mixture shall then be placed in forms and closed. After a chemical reaction the volume will expand and cover the form entirely and turn from liquid to solid form and shall be removed from the form as an interim product. The bottom surface of the external unit (3) is covered to prevent the creation of the vertical mortal heat bridge. The upper surface of the external unit (6) whose four corners and the base are in the shape of a monoblock is left open If the internal unit (7) is made of foam concrete or concrete made of light aggregate the known methods shall be used; The wet foam manufacture with synthetic protein and/or fluorprotein foam extract, shall be processed in a concrete plant according to the concrete recipe (with natural and sifted sand, bims, eps polystyrene particles, volatile ash, etc) and shall be placed in the external unit (1) while it is still wet without being reinforced. When the concrete placed in the external unit (1) hardens the product shall have taken its final form. The unit volume weight of light foam concrete is between 400-500 kg/m3. The concrete of the internal unit (7) may be produced by wet foam made of synthetic, protein and/or fluoroprotein foam extract and/or with all types of light aggregate (natural and crushed sand, bims, eps polystren particles, volatile ash etc) and used in the product. In this process the unit volume weight of the concrete varies between 500-1000 kg/m³.

The top and bottom telescopic teeth (4) and the left-right telescopic teeth (5) of the insulated and light construction materials designed and produced in the manner explained above shall be bounded during the construction of the walls of the buildings and shall be connected with each other by confining the connections inside the building mortar. The product has channels (9) in the shapes and depths to insure the product sticks to the surface (8) on which plaster is to be administered. The product to be used on the ceiling ASMOLEN shall be manufactured with the same materials in the same manner in different sizes only.

If the product is manufactured by combining polystyrene or polyurethane whose unit volume density is 15-30 kg/m3 and heat insulation coefficient is 0.031-0.04 W/mK with concrete made of foam concrete or with light aggregate with pores and whose unit volume density is 400-500 kg/m3 and heat insulation coefficient is 0.16-0.19 W/mk in the manner and fashion explained above; the new combined material will have a weight of 300-350 kg/m3 and a heat insulation of 0.06-0.08 W/mK shall be a new product which will also serve as an insulation material. If the new material is used in the wall system of the buildings it will provide heat-sound and water insulation, reduce the cost of materials and labor and the expenses incurred from heat loss, and will provide high quality, simplicity, comfort, safety of life and commodities.
