Abstract

Use: construction of buildings with lightly loaded foundations (or foundations of shallow laying) on heaving soils under conditions of their deep seasonal freezing, ensuring increased durability of the building and reduced operating costs. SUMMARY OF THE INVENTION: The foundations of a building are placed inside rooms provided with heating devices, which is not sufficient for an external zone of seasonal soil freezing. The wall fencing is mounted on the console around the building perimeter. 5 il.

Description

The invention relates to the construction of buildings with lightly loaded foundations (or with fine foundations) on heaving soils in conditions of their deep seasonal freezing.

The purpose of the invention is to increase the durability of buildings and reduce operating costs.

Figures 1 and 2 show industrial and residential buildings, respectively, cross-sectional views; Fig. 3 shows the building plan; Figs. 4 and 5 show constructive embodiments of mounting the wall fence to the frame console (node I in Figures 1 and 2) and deepening the wall fence in heaving soil (node II in Figures 1 and 2).

A building erected on heaving soils includes light-loaded foundations 1 (or foundations 1 of a shallow foundation), the soles of which are located within zone 2 of seasonal freezing of soils in natural conditions, the supra-fundamental structure made in

the form of two-console longitudinal and transverse frames 3 supported on foundations 1, and an external wall fence 4 attached by the upper part to the brackets 3, and the lower part is embedded in the ground of zone 2, and equipped with heating devices 5. The width of the superstructure around the building’s perimeter , corresponding to the flight of the cantilevers of frame 3, is equal to the depth of zone 2 of seasonal freezing of soils in natural conditions. The upper part of the wall fence 4 is attached to the brackets 3 with the possibility of vertical movement by means of, for example, an extension 6 of the T-section and a bar-shaped grip 7. The lower part of the wall fence 4 is buried in the ground, provided with an anti-tear device, for example, in the form of side shields 8 zankerennyh in the backfill 9 of coarse-gravel soil with the formation of the cavity 10, the blind area 11 and the apron 12, also providing the possibility of vertical

movement of the wall fence 4.

A building erected on heaving soils under conditions of deep seasonal frost penetration works as follows.

The wall fence 4 (together with the overlap or the covering) maintains in the inner and outer rooms a positive air temperature created in winter by heating devices 5. From the leveling surface, the soil freezes down to the building down to the depth Niv of the building by width B, equal in the worst case H, forming a zone of 2 freezing. Due to heat loss from the premises to the ground, zone 2 of seasonal freezing is shifted along the perimeter to the external contour of the building in the plan. Due to the fact that the wall fence 4 is placed on the brackets frame 3 with the width B not less than the depth H of the seasonal freezing of soils, the foundation of foundations 1 becomes unsuitable for seasonal freezing and the possibility of the formation of freezing ground forces at the base is excluded. The outer wall fence 4 is subject to seasonal deformations (lifting in winter and lowering in summer), however, these deformations are weakened by anti-puncture devices and are compensated for by the possibility of vertical movements in the joints with the console 3 at the top and with counter-objecter devices below. For example, the easing of deformations from the heel forces is ensured by backfilling 9 of large-skeletal material draining free moisture, apron 12 and washing-out 11, diverting atmospheric water into

the side of the wall fence 4, and the possibility of vertical movements is created by the side shields 8, anchored in backfill 9, and the cavity 10 between them to move the lower part of the wall fence 4. The possibility of vertical movements in the upper part of the wall fence 4 is ensured by sliding the tread 7 by T-extension 6.

The proposed solution allows to exclude seasonal deformations of the building core and, thereby, increase the durability of the building. At the same time, the operational costs of eliminating the effects of deformations of the frost heave are reduced, since only external wall fences (and not the building as a whole) are subject to them to a lesser degree without causing internal stresses in them, leading to destruction.
