Monolithic strip foundation - from measurements to pouring their own

monolithic strip foundations - what is it?

Typically, monolithic foundation tape device is planned for buildings with heavy materials in the structure of the walls: stone, brick, concrete, adobe etc.The advantage of this type of substrate is high reliability and durability.Unfortunately, building a solid monolith consumes a large amount of funds and materials.Therefore, the feasibility of such a structure is recognized only at shallow depths bookmarks.And this applies especially to the project structures with basements.

necessary calculations tape monolithic foundation is conducted not only on the basis of the density of the soil site.When calculating the belt width of the sole taken into account the load value on it, depending on the number of floors, wall thickness and so forth.

In some cases, such a monolith may take the form of a solid plate or box around the perimeter of the building.The practice of applying the combined sealing packing of soil or sand piles or w / w of the columnar structures.In most cases, given the same load on the entire length of the tape, the calculation is conducted on a segment of one meter.

Design tape monolithic foundation - basic calculations

Starting to build solid foundation tape with your hands, you need to decide the size of his burial.This option is for a particular site.The beginning will be the pit to a depth of two meters.This will let you know well the structure and quality of groundwater, the water level of occurrence in it, freezing depth.A common reference point may be heaving soils.Nepuchinistye allow the installation of the foundation to any depth, but not less than half a meter (regardless of freezing).

for heaving soil depth definition more complex and may have some additional adjustments.So, when the water level in the ground deeper than two meters above the norm preserved.But even at occurrence of less than two meters monolithic concrete foundation tape need to bury three-quarters the height of freezing settlement, from 70 centimeters.If groundwater rise above this depth to bury the tape main support need not less than the whole layer.

defined the desired depth, design tape monolithic foundation continue to the choice of material.You can do it, using rubble or rubble concrete.In the first case, the course is a stone with an irregular shape (torn bottles).

tape width to do so at least half a meter, taking into account that it is five to ten centimeters wall thickness must exceed this difference is greater than the inherent deeper base.So, for the depth meter tape should be wider than the wall for twenty-five centimeters.

rubble concrete belt solid foundation, the size of which shall be not less than thirty-five centimeters (wall thickness), has a number of advantages, such as lower labor and the possibility of use on all types of ground soil and the disadvantage is a large cement consumption.It is performed by pouring a prepared foundation composition in the form shuttering installed in special trench.

Phased tape device monolithic foundation

Before laying in accordance with the plan of digging trenches .In the course of this work important thing is the preservation of the strength of their walls.Cohesive soils allow you to do the vertical walls, they are usually used as formwork.Sometimes the excess of the maximum depth of the trench is a meter and a half, depending on soil type.

Trenches under the belt foundations monolithic melkozaglublenny necessarily protected against ingress of water, for which the surrounding area specifically develop, including the release of soil on the hill side.Selecting an earthen mass begins with the lower points of the plan.If necessary, arranged drainage.It is undesirable to excessive penetration, such places should go to sleep gravel and sandy material with seals.

Trenches, which is arranged flush monolithic strip foundations should be strengthening :. Rack panels with spacers, etc. They also can be installed directly formwork, especially on clay soils.Bookmark at great depths can be carried out with a permutation of the formwork panels according to the rules of education workers and cold joints concreting.

When the rubble stone foundation structure must first be selected and placed on the size of the solution.Rubble concrete are built layer by layer by immersing the stones in concrete without the obligatory sorting and ligation sutures.If concreting suspended for six hours or more, the top row of stones poured concrete only half.In the future, you need to renew the work of such density solution that allows the free retraction of stones without the need for tamping.

as you would with a reinforced concrete steel frame formwork can only be removed after a week and placed concrete should be covered matting, burlap, straw and periodically watered.During the work carried out all necessary measures for waterproofing roll materials on bituminous ingredients, just bitumen or its solutions, etc.
