The invention relates to the field of construction of residential buildings, and more specifically to a shallow foundations, such as for homes, houses, cottages indie who's highly effective Foundation structures, steady on weak ground.Creating this type of Foundation is dictated by the requirements of the geological conditions subsiding ground.Known precast concrete frame of the underground part of the building, including upper and lower horizontal elements connected by struts, and the upper horizontal element is designed in the form of two cantilever beams, and the rack is tilted and contiguous to the axis of the lower horizontal element .A disadvantage of the known technical solution is low reliability on soft soils because of the low spatial stiffness due to the high premnote frame.Known reinforced concrete frame frame of a building or structure, including arched foundations, columns, pins arched shape, rigidly interconnected, and a frame made in the form of a single element, and the radius of the arched Foundation equal to half the span of the frame, the radius of the bolt - the distance from the connection node of the bolt with the column to the center of the circle arch Foundation .A disadvantage of the known technical solution is the low reliability of foundations on soft soils due to weak supporting part and sustainability, significant regulatory strprice Foundation made in the form of plates with the lower curved convex surface and placed freely on the layer of soil, formed from a cushioning material, while the frame is made rigid and is rigidly connected to the Foundation, and building height equal to or less than its minimum size in terms of  .A disadvantage of the known technical solution is low reliability on weak soils from decreasing stability with increasing height of the building.The closest to the essence and the achieved technical result is the construction of the reference node of the building structure, including the prepared base and beam elements in the bearing structure .Analyzing as shown counterparts, and were not included in the application for the analysis of descriptions of known sources of information, we can conclude that, regardless of the type and size of the known constructions the reference node to solve the problem of reliability and simplicity of construction, but not suitable for weak soils.The objective of the invention is the creation of a Foundation structure increased resistance on soft ground and a significant simplification of the structure.The problem is solved due to the fact that the basic unit of the building structure, including the prepared base and beam elements in the bearing design is, and includes a reinforced membrane, the box-shaped enclosure base and convex downward beam crossbar with base plate, when the thickness of the membrane and the support plate, equal to not less than 1/2 of the thickness of the beam cross members, the ends of the crosses have the profile of the slot sections and rigidly clamped at the corners in the openings of the fence cap and heel support plate cross relies on monolithic geomusic mounting horizon.The execution site in the form of monolithic reinforced concrete structures, forming a three-dimensional harness, allows to increase the reliability of the design thanks to the rigidity of the overall relationship.The use of reinforced membrane ensures the stability of the structure.Application of the box-shaped fence cap with a convex bottom beam of the bearing shaft and the support plate provides a simplified design reference node, at the same time retains rigidity and increased resistance in General the entire area of the sole support plate on emassive mounting horizon. The ease of communication also allows to reduce the complexity and processing time on the construction of the reference node.Use at the ends of the beam crosses the profile of the slots, and hard of sealing at the corners of the fence which ensures the overall stability and load stability at various disturbing loads.Performing beam crosses with base plate increases the stability of the reference node on soft ground, through the distribution of perceived load when the contact bearing surface of the plate with geomassiv.The presence of the thickness of the membrane and the support plate crosses, equal to not less than 1/2 of the thickness of the beam crosses, simplifies the design with guaranteed reliability.Using the thickness of each of the beams cross, commensurate with the thickness of the fence, can simplify the design by using a single dimension elements between the reference node and provides a margin of safety of all elements with the same structural rigidity.Between the features and the aim of the invention there is a causal relationship, in which the technical result due to the positive effect of the increased stability on soft soils and simplify the design.The proposed solution can be commercially reproduced in mass production by conventional plant equipment.The invention is illustrated graphic material, where: - in Fig. 1 shows a General view of the reference node; - Fig. 2 is a top view; Fig. 3 - VI is itnow reinforced concrete structures, forming a three-dimensional piping, and includes elements of the supporting structure, reinforced concrete membrane 1, a box-shaped enclosure of the base 2 and the convex bottom beam crossbar 3 with base plate 4. Each end of the bearing yoke 3 has a profile sections 5 and slot 6 for sealing the corners of the openings 7 of the fence cap 2. The elements of the carrier beam crosses 3 made of reinforced concrete with tarooborot shape in cross section. Valid elements with the shape of the I-beam, rectangle or cylinder. All sections must have at least one axis of symmetry. Reinforcement symmetric. The size of the brand is not less h mm Heel support plate 4 carrying the crosspiece 3 is based on a monolithic geomusic 8 prepared in advance of mounting horizon 9. The thickness of the membrane 1 and the support plate 4 of the carrier 3 crosses at least 1/2 of the thickness of the beam crosses 3.The thickness of each of the beams crosses 3 commensurate with the thickness of the fence cap 2. In General, for the construction of the reference node used concrete B-20.A box-shaped enclosure of the base 2 itself includes a rectangular enclosure 10 and additional functional section 11, the edges of the walls which zamonolichennyj in the enclosure of the base 2 and in General create a General box-like shape. The more elements the second reflection. Profile of the slot 6 of the bearing yoke 3 made of an acute-angled shape with a slope to its end. Sections 5 made according to the cross-section of the bounding planes of the limitations of the cap 2 horizontally and vertically. Geomusic 8 mounting horizon 9 is prepared in advance before assembling the reference node than create volumetric stiffness strapping Geomatica 8 by tamping and subsequent compression to the required coefficient of elasticity of the soil Geomatica 8. For compression first, make holes with a diameter of 50 mm, insert there the cups 12 with holes. Further, under the pressure of the liquid solution. The result is geomusic 8 used on the mounting area, suitable for the construction of buildings without digging the pit for the Foundation. Since the reference node based directly through the support plate 4 of the carrier 3 crosses directly on geomusic 7 on the plane of the ground mounting horizon, the structure itself will be respondentsin. His role with the success of the reference node, in which the sole support plate 4 of the carrier 3 crosses experiencing constant intense pressure. All points of the contour of the sole support plate 4 have concentrated load power.Advantageous location of the normal jet pressures not POPs the second plate 4. Changing the geometry of the supporting elements contributes significant differences and changes in the current practice of building foundations on soft soils for residential premises of the individual building. The simplicity of the design reduces considerably the technical time for construction of this Foundation, economic and technological resources, which ultimately indicates a promising technical solutions proposed.Consider the technical solution is useful in the construction of shallow Foundation under the house with regard to the reliability and simplicity of construction, which contributes a significant consumer demand in construction and is especially important when the current existing shortage.Sources of information 1.
