Light weighting, reducing administrative costs, and reducing energy consumption in buildings are very important factors. Applying essential techniques to realize all of them at the same time decreases work costs in time of construct, and decreases energy consumption in operation time. Walls are one of important components of building. Above mentioned items should be applied for them. As there are many walls in buildings, any positive change in them, could be an important step in this regard.
Chalk is one of the cheapest and most abundant materials in the world. History of use of stucco panels for the implementation of retaining walls is about 40 years. Despite the cheapness of these panels, there is not possibility of using them as a side wall or in the bathroom and toilets, because stucco does not stuck to cement. Its parts are relatively high weight. SP composite panels are used as non-load-bearing walls, including internal retaining walls or side walls to light weighting in building, and decreasing costs of work.
SP is a new form of stucco panels. As white stucco is used in it as its main raw material, it is very cheap. Its surface is flat and it is ready for coloring after putting a thin layer of stucco on it. Unlike ordinary stucco panels, it is possible to use SP as the side wall of the façade, also in wet places such as bath room and WC.
Invention advantages are as follows:
It is ready for coloring or any other inside cover by run a thin layer of gypsum plaster on the wall.
Support 5 and sheet 6 run by screw 7 to provide mechanical connection on it. Inside part is where a white plaster layer is on it, ready for coloring or any inside view on plaster. Notably, it is possible to implement support system and metal net on both sides of wall, if it is necessary. External components of SP were shown in
1: It is the main body of SP; that is made of a combination of white plaster and water. Dimensions of this piece are varied but the best one is 666 mm length (L1), 500 mm height (h1), 100 mm depth (d1). It is recommended for better attachment of parts together, such as the figures displayed. There are tongues and grooves in 4 sides of it. A Yonolit 8 (also known as polystyrene) is placed inside this panel. A-A and B-B cuts are considered to be shown. 2-1 and 3-1 components of parts 2 and 3 are visible in the figure. Screws 7 are anchor there, and connect metal supports 5 to the outer body of wall.
5: is a bent metal sheet (support). Its length depends on width of wall. Its thickness should be 1-2 mm. it was connected by screw 7 to components of 2-1 and 3-1 in panel. More details are in map 7.
6: is a metal net sheet. It is connected to support 5 by screw bit 7, as it covers all surface of wall. It provides complete connection between cement mortar and SP. Dimensions and width of these metal nets are different, but it is better to use galvanized Rabyts sheets.
7: is screw bit. They open their way without need to drilling. They increase their speed of work. A-A and B-B cuts are shown in
Part 8 is a slow-burning Yonolit sheet to decrease weight of panel, and creating a thermal insulation by parts 2 and 3 in production time is placed in the middle of panel. Dimensions of part 8 depend on dimensions of SP. But, it is suggested to select its dimensions as gypsum slurry covers at least 5 mm around it. 3 dimensional views of parts 2 and 3 and 4 side views of it are shown in
Components 2 and 3 have double application. Their first application is in panel production time. It is connected to Yonolit 8, such as
Bending method of part 5 is different, but it is suggested to bend it, such as
A proposed section for part 5 is shown in
5-2 is bending location of sheet 5. Bending angle should be less than 90 degree. 5-3 is diagonal member of part 5. It provides essential distance between sheet 6 and SP. its length should be 10-15 mm. 5-4 is re-bending place of sheet 5. According to bending angle, 5-5 member should be parallel to 5-1 member. 5-5 point plays an important role in mechanical connection of cement mortar to SP. Its length should be 10-15 mm.
