The device of the built-up roof on a roof of an industrial building
Quite often, industrial buildings in need of repair. In our country, a lot of such facilities, the commissioning of which occurred at the time of the birth of our grandmothers and grandfathers. Naturally, over time, no matter how well built at the time, everything starts to fall into disrepair. The facades, internal walls are cracking, roofs begin to flow. There comes a time when it is necessary to seek help from construction organizations and repair or renovate.
Omitting all aspects related to the preliminary period, including the passage of the tender, the preparation of project documentation and the like and going directly to the main stages of construction, it is worth noting that they are divided into several independent types of work. Among them are works related to internal structures (floor walls), works with external walls (facades), as well as roofing works.
Roofing works are carried out on the basis of the approved project of work (PW) and working documentation, including drawings, schedules and estimates.
The device of the roof of PVC membrane. Preparation of the base and the final stage.
Before repairing the roll roof, a number of works are carried out, which together represent the preparation of the foundation for the roof. In general, this represents a device of cement-sand screed with a thickness of 20-40 millimeters, the installation of a vapor barrier film and insulation (mineral rocker Rockwool). When calculating the preparation under the roof, it is necessary that it can withstand the load, which is called pulling out, previously calculated in the project. The works themselves are carried out in the following order:
1. On top of the coating arrange vapor barrier film. She needs to be laid in view of the lining about 0.8 meters and make the joints with a special adhesive tape. In areas adjacent to the elevations (parapets), it must be raised to a height equal to the thickness of the insulation.
2. Next, carry out insulation. Lay the bottom layer of minpliti, 100 millimeters thick. Next, it is laid on the top layer with a thickness of 50 millimeters.
Mineral wool plates are fastened to the base (slab) with the help of fastening elements, such as dish-shaped anchors: self-tapping screws, 100 millimeters long and with a drill of 60 millimeters.
3. Subsequent work is also a vapor barrier made of vapor barrier film, which is laid on the insulation.
4. The following paper presents a device for laying out of expanded clay concrete. Bias may be different. For example, 60-200 mm.
5. On a razuklonke the protective reinforced coupler 30 mm thick becomes. Usually from a solution of mark M100 on a metal grid 4 mm thick. with cells 150x150 mm. After drying screed surface primer primer.
Installation of PVC - membrane by fusing.
The device of rolled roofing is carried out using mechanical fastening
The mechanical method is mainly used on pitched roofs, while fusing is performed on a flat surface. Fastening of the material occurs when using molten bitumen. Used gas burner. Rolled waterproofing rolls overlaid on each other by 120 mm. In the area of junction with the parapet, waterproofing rises to a height of at least 100 mm.Fastening to the parapet is made by applying welding. Membrane as it covers the entire top of the parapet and lower it to the outside. Produce mounting screws. From the inside they weld along the horizon and produce a hard grip with the main carpet.
