Description

The invention relates to a graft base for halls and technological equipment.

The existing foundation of the hall splits consists of a group of vertical and inclined piles, above which is created a rigid connecting structure - foot, which divides the loads from the splits into individual piles. The foot is formed as a continuous structure under the entire column of constant or graduated height. The procedure for the production of existing foundations requires first to excavate the expanded foundation pit and after the pile has been prepared, clean the foundation joint of the foot, spread the foundation concrete, install the formwork, store the reinforcement, the concrete mixture and compact the backfill. The production of graduated feet is more complicated, as the upper stage is plowed and concreted only after the previous one has set.

The disadvantages of the existing foundation of the hall splits lie in the fact that it consists of a connecting structure between the piles and the column, which is formed as a large foot concreted in an open trench into inventory or lost formwork. The abovementioned foot production process greatly reduces the importance of highly mechanized and efficient pile technology for the substructure industry.

The above drawbacks are overcome by a pillar base formed from piles and a connecting structure, the essence of which is that the joining structure consists of two or more blocks located at the anchorage point of the pillar and coupled at the top by a plate.

At the bottom are blocks associated with pilots. The blocks have anchoring elements on which the pin is mounted. Another basis of the graft consists of blocks made up of large diameter piles. The blocks are formed appropriately to the load of the graft, the axial distances of the anchoring elements, the number and size of the piles.

The invention makes use of the fact that, by its stiffness, the steel foot of its own graft can transmit post-torque moments and forces to a punch formed from piles and two blocks, which are top-coupled by a plate. From a static standpoint, the base of the present invention operates by splitting the splitting moment into a force pair, whereby the force acts on one block as pressure, on the other as tension. The normal force is distributed over the same pressure components acting on both blocks.

On one block, forces are added as pressures, on the other, the resultant is the difference between the two components of tension and pressure, and there may also be a thrust that can transfer piles to the soil to a certain thrust value practically without pulling. The differently retracted blocks supported by the piles show at least the differences in seating, which ensures the horizontal alignment of the stowage and hence the rigidity of the hall construction.

The co-operation of the blocks under the column is ensured in the horizontal direction by the plate. Heavy horizontal loads can transfer blocks when they are concreted into boreholes like large diameter piles.

The technical advantages of the solution according to the invention reside in the removal of the rigid connecting structure - the foot under the entire column, thereby significantly reducing the weight of the foundations and making the construction easier at all. Another advantage is the construction solution by making the blocks mechanized - as large-diameter piles, while traditional foundation technology is only applied to thatch that is lightweight. This achieves a substantial acceleration of the plower plow.

A further development of the subject matter of the invention is shown in the accompanying drawings, which show vertical sections taken along planes of symmetry of the foundation and horizontal sections taken along a foundation at different depths. 1 to 5 are cross-sectional views of a steel hall chip consisting of piles and two circular cross-section blocks coupled with a plate and provided with anchor bolts for fixing the hall chip, wherein FIG. 1 is a vertical longitudinal section through the foundation and the schematic diagram of the column; FIG. 2 is a vertical cross-section of the base to the right of the plane of symmetry A-A in FIG. 1, FIG. 3 is a horizontal cross-section of the plate B-B in FIG. 1, FIG. 4 is a horizontal cross-section of blocks C-C in FIG. 1 and FIG. 5 is a horizontal section through the piles D-D of FIG.
