Foundations under the stove

Foundations for stoves usually have the same area as the laying of the foundation of the furnace. In the two-story homes on the edge load is the foundation of the furnace from a solid brick does not exceed 2000 kPa. For furnaces of ceramic blocks such loading is reduced by about 15-20 times as the sectional area Flue riser in this case is much smaller. Scattergun basement furnace in a house without a basement have a nepromerzayuschey area not less than 50 cm from the ground. When placing the furnace on a basement foundation furnace deepened to 30 cm below the floor level basement. Oven bases are made of gravel-sand mortar or concrete. Precast concrete and reinforced concrete foundation reduces the amount of masonry and allow them to mechanize the assembly. They consist of pillows - concrete blocks (plates) of rectangular or trapezoidal shape to be placed on the preparation of thick sand rammed 0,15 m and a vertical wall of concrete blocks (Fig. 33). When weak soils in the precast concrete foundations suit belt thickness of 100-150 mm thick reinforced seams 30-50 mm. Pier foundation can get a separate support buildings - a concrete columns, brick columns, etc. (Fig. 34). Solid foundation for doing in the form of a monolithic reinforced concrete ribbed slabs, it was appropriate for the need to protect the basement from the penetration of ground water with high hydrostatic pressure.
