Everything is painted in the article about the slope of the scene (about the angle of inclination 1 m). Snip norms in centimeters and degrees around the house, minimum and maximum bias requirements. It is indicated how to make a specific slope from concrete.
Why bias is important?
To deal with the angle of inclination of the scene around the house, it is already necessary due to the fact that it is she protects against sedimentation of precipitation down. That is, from the designed structure of the structure with everything that is so expensive in it for residents. But even if the scene seems to eat, it sometimes fails. And it is connected just with illiterate decoration of the slope. This parameter directly depends on other design characteristics, and ideally, everything should be calculated immediately.
Construction rates and rules say straight that the width of the design should be 1 m. Deviations from this value are allowed in exceptional cases in the presence of a technical substantiation. On clay soils, the risk of damage to the building is great, because the sand layer must be increased to 0.3 m. Only such a bookmark guarantees the reliability of the arrangement.
What is interesting, you will also have to take into account the roofing sinks. The width of the scene must exceed the gabarite sweep of at least 0.2 m. According to the standard, the decline of the shock begins strictly from the foundation of the building. This requirement allows precipitation and thawed water to be easily leaking and go to the ground.
Curvate should be calculated according to accurate width and applied materials.
So, When using rubbank and cobblestones and a width of up to 1 m, the minimum level of slope in degrees is 5, and the maximum – 10. But often the scene is made on the basis of asphalt or concrete. Then its curvature reaches from 3 to 5% of the total width. Many parameters are also set in GOST. So, standard 9128-97 regulates the composition of the mixtures that are allowed to apply for the arrangement of the scene.
Recalculate the curvature disruption specified in the normative acts into familiar metric units is not difficult. But – only for professionals. The newcomers and directly customers are desirable to focus on popular standing standards. According to them, 1-1 m surface should accounted for 1-10% of the curvature. In centimeters it will be from 1 to 10 – and withstand such a parameter, as practice shows, not too difficult.
But sometimes characteristics are different. For concrete or asphalt, they are equal to 0.3-0.5 cm, depending on the specific situation. Always take into account practical subtleties, and only professionals can be performed correctly. The transverse bias from the walls of the building is no less important than the longitudinal slope – its indicator should be at least 2%, and according to some information, even from 3%.
This requirement is also very clear; In the construction rules (SP) on the improvement of the same figures that are given above.
How to do it?
But simply choose in tables and regulatory instructions, those or other numbers are far from enough. Directly construction work frequently faced difficulties. And one of the possible problems – how to calculate the necessary deviation not on paper, but on concrete or other material. There is only one way out: use the building level. They are fluent in laying twice: when they prepare the design itself and when they decide whether it is ready; After some time, fix the error will be difficult.
During the construction of the breakfast, it is impossible to forget that it must be agreed with the drainage complex. It is about compliance with drainage and tilt and need to think first. Between the pipes, pulling water, and the design exhibited around a private house or other building should remain as few times.
This is the main requirement, without complying with which it is simply nothing to say.
The sequence of work is as follows:
- Marking of the territory (stakebringing, pulling the cord before the smooth line appears);
- Careful removal of the upper tier of the Earth (usually 0.25 m, but you can definitely say depending on how much concrete mix is to be protected);
- Careful inspection of the dna dance, root roots and treatment with drugs that interfere with sprouting plants again;
- Preparation of formwork based on an unedged boards with a thickness of over 2 cm;
- layout of the pillow (most often under the device from concrete, use a sand pillow with a minimum value of 5 cm, preferably even more);
- Mounting of the frame (for it takes high quality reinforcement);
- Pouring with concrete going at a given angle.
Of course, a standard approach may vary significantly due to circumstances. So, Instead of pure sand on the bottom of the trench, a sandy-crushed composition is often put. A similar pillow can be tamped, and the optimal value of the layer is 0.15 m. Over the pillow lay out thermal and hydraulic barriers. Regardless of the design slope by 1 meter, setting a break above the surface is needed by 0.05 m.
The tape used for the pedestrian walkway must meet higher requirements. It necessarily has high strength. The width of the strip must be higher than usual, which allows you to ensure the comfort of moving. Important: exceeding the regulatory level of slope is undesirable. When the indicator is exceeded by 10%, the outflow of water will occur very quickly, and the edges of the scene will be destroyed extremely intensively.
Prevent such a situation is possible with the help of gutters. They guarantee the most effective disgusting of water. Filling technology intuitively understandable and as close as possible to the arrangement of the concrete sidewalk. For protection against water, pvp membranes are often used.
However, it eliminates the possibility of a pedestrian track.
Subtleties are as follows:
- It is impossible to rigidly connect the scene with the walls;
- So that the soil does not harm, the sealant should be used on a polyurethane based or damping tape;
- We will have to equip transverse seams to compensate for deformations.
Concrete casting most practical. Even the unprofessional. The greatest depth of the breakfast is 50% of the depth of which the land is free. If the car will ride it, the thickness of the flooded layer is increased to 15 cm. Concrete B3,5-B8 usually apply for the formation of the solester.
For bookmark Pillows use both river and career sand. Optimal rubble fractions – from 1 to 2 cm, the use of gravel is allowed. Ironing is carried out with cement. Whether to use the finished solution or knead it independently depends on the situation.
It is recommended to use fresh cement.
Enhance the resistance of concrete to cold helps the additive of liquid glass. Water to knead the solution is best to gain in a measuring container. With self-laying, the cement mixture is prepared with minor portions, which reduces the probability of error. Hydrodes are usually made from oily clay. Improve the quality of drainage helps a pipe wrapped by geotextile.
The suppression of cold bridges is achieved with double thermal insulation. It is organized by the reinforcement grid with a square cell. Side of cells – 5 or 10 cm. Binding the reinforcement frame with a chain grid undesirable because it is too flexible.
Wet iron is made on day 14 after fill.
