Description

The invention relates to the construction, in particular to the arrangement of basements of frame buildings under conditions of a high level of groundwater.

The purpose of the invention is to reduce the material and labor intensity, and increase the durability of the slab structures in soils with aggressive groundwater.

FIG. 1 shows the basement of the building framework, a transverse section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - node J, in FIG. one.

The basement of the frame building includes a slab 1, placed on preparation 2 on layer 3 of horizontal insulation, supported on slab I of the foundations (not yet zapy) with columns 4, ceiling 5 and device 6, extinguishing hydrostatic nano group 1) 1k under.

 The device 6 for extinguishing the groundwater pressure head 1 is made in the form of ground anchors placed between the foundations of the columns 1 and attached to the slab 1 by means. prefabricated distribution washers 8, the latter being made of trapezoidal section with a smaller lower base and covered with a waterproofing layer 9.

In order to increase the durability of the structure of the slab in soils with aggressive groundwater, the distribution washers 8 can be made of i-concrete and installed. on horizontal waterproofing 3 across layer 10 mastic.

The basement is erected as follows.

In the excavation, ground anchors 7 are made, then concrete preparation 2 is installed, waterproofing 3. from asphalt or cement concrete. On bearing rods of ground anchors 7

The distribution washers 8 are fastened with the help of hardening material 11; they are installed on solid hydroylation 3 with the help of waterproofing mastic. The same mastic additionally assembles the joints of the bottom surface of the washers 8 with waterproofing 3. After the protective coating of the waterproofing layers 3 and 9, reinforcement and concreting of the plate 1 are made, in which glasses, reinforcement fittings or other elements are fastened columns 4 basement.

The construction of the basement frame frame is as follows.

The forces from the overlap 5 are transferred by the columns 4 to the plate 1. The hydrostatic pressure acting on the plate I from the bottom is perceived by the ground anchors 7. The forces from the anchors 7 are transmitted to the plate 1 by means of distribution washers 8, the design of which ensures the transmission of forces from the anchors 7 to adjacent areas L1LITES 1 and ensures the integrity of the waterproofing of 3 and V c. the ground points and anchors 7 to the plate 1. The transfer of the UCI.LIH from the hydrostatic pressure to the plate 1 is carried out by the interaction of the consoles of the projections 12 and 13 around the perimeter of the washers 8 and the plate 1. The bending moments in the areas of the plate 1 between the anchors 7 are reduced due to the installation of columns A in the spans between anchors 7.

The basement can be erected in any soils, but for each type of soil it will differ in the design of the soil anchors 7. For example,

A screw ground anchor (sand, loam) is possible to use screw anchors, for rocky soils - drilling anchors with rods, permanently; drilled in wells.
