The invention relates to metal structures, mainly the frames of industrial buildings.

Known hollow cone reinforced concrete Foundation.with. N 83768, CL E 02 D 27/52, 1977). There is also known a method of rihtovaniya Foundation.with. N 1335657, class E 04 B 1/02, 1987). Take these decisions for the prototype. The disadvantage of the prototype is the increased complexity of manufacturing, installation and rihtovaniya.

The purpose of the invention is to reduce material consumption and improve the reliability of the Foundation and the connection node of the column base, and reducing the complexity of the straightening of the frame.

The goal is achieved in that the metal column connected to the base by means of two conical metal shell, tightly stuck to each other, a length of 1.2 to 1.5 the height of the column cross-section with the same slope of the generatrix to the axis of the column (2-3o) with machined flanges, one of which is fixed teeth retainers, and in the other holes, and the outer konusnom longitudinal rebar, bent at an angle of 15-45oto the axis of the column, covered ring terminals and forming reinforcing steel flaring cone, which is the reinforcing cage of the hollow concrete cone Foundation, the cavity of which is filled with granular material resting on the subgrade.

The method of construction of the Foundation under the metal pillar includes the manufacturing of the base with a cavity connection with his column, production geodesic breakdown of the location of the Foundation, placing it in a project position and the cavity filling material, which rest on the ground. This is made tightly stuck to each other conical metal shell, weld flanges with holes, one of which is provided with teeth-clamps, weld the outer conical shell pattern small base to the column, and to the inner membrane from the inside to the larger base of the weld longitudinal bars bent at an angle 14-45oto the axis of the column span of the longitudinal rods of circular rods with step 100-400 mm, forming a reinforcing cage, perform in the center of each column cone of gravel, put on the last valve cone together with steel untremendo combine it with the reinforcement cage, set the jig and rightout in space reinforcement cage with the inner shell and formwork, fix them in the design position, enter the concrete pump hose into the mouth of the inner shell and concreted cone Foundation with vibration, and after concrete setting without adjustment mount metal column, putting on top of the steel outer conical shell columns on the inner membrane of the Foundation, combining the teeth retainers with the holes in the flange and tighten the friction stud flanges.

Thus, the formed hollow cone Foundation, the cavity of which is filled with rubble, and the top of it is placed a conical shell, and made non-calibrating the installation of the column.

Perform filling the cavity with gravel provides maximum surface roughness in the area of its contact with concrete hollow Foundation and helps to reduce effort in the annular reinforcement of the Foundation. In order to reduce effort in the annular valve, the bottom of the Foundation is perpendicular to its generatrix.

Alignment of the Foundation of manufacture or after manufacture of the foundations (if poor work performance), or after operation of the building during nekotoroh the AE is leveling the finished cone foundations and identify foundations, made below the design elevation and determine the required size of straightening heightinprivate foundations.

For straightening applies sand mortar or sand slurry with the addition of a plasticizer, such as clay. Is the clean channel in the nozzle 10 and the adjacent layer of crushed stone backfill. Concrete is destroyed by drilling or breakdown with a jackhammer and a special pointed punch the required length.

To reduce labor costs in the future when the straightening of the entire frame of the building after the operation and uneven precipitation of the columns rationally pipes 10 to be cleaned 1-2 hours after concreting, i.e. when the concrete has not yet gained strength.

With a pipe 10 connects the hose and force in crushed stone backfill injected plastic pulp that fills all the voids in the gravel and podogrevom the Foundation to the desired value. The lifting force can be created such that raises the building any mass. For example, when the excessive pressure of the pulp of 1 ATM creates a lifting force of 10 t/m2, i.e. the area of the Foundation 10 m2lifting force on each of rythemic columns will be equal to 100 tons

CPE is to be the Foundation as a whole. Otkatyvaetsya only the nozzle 10 of the Foundation, which is arranged in the upper part of the basement and can even be displayed inside the shop.

In this case, the earthworks are not produced as slurry pressure enough to overcome not only the weight of the building, but a lot of the soil that fills the cavities of the Foundation.

In Fig. 1 shows a developed Foundation in the context of Fig. 2 - the junction of the column base in the Assembly of Fig. 3 is a view of A.

Concrete hollow cone Foundation 1 filled with granular material 2, such as gravel or slag. Reinforced concrete Foundation 1 goes into steel inner conical shell 3, oriented with the top up. It is worn on top of a conical shell 4 columns, oriented pipe down.

Broad base inner 3 and outer 4 shells provided with flanges 6, one of which is placed the teeth of the clamps 7, and the other the return holes. The contact surfaces of the flanges milled.

To the inner surface of the tip 3 is welded longitudinal reinforcing bars 8, bent at an angle of 30-45oto the longitudinal axis of the column. The longitudinal rods 8 are covered ring terminals 9 in increments of 100-400 mm To Armaturen 1 concreted in layers with a gradual increase brand concrete, that is, the upper layer is the most durable. Reinforcing cone frame is fixed nozzle 7 for discharge of concrete.

After installation of the casing and connect it with a conical frame and the inner conical shell 3 is the spatial alignment of the collected construction as a whole through a conductor (not shown) and fixing it in a project position.

Non-calibrating the installation of the column is performed after hardening of the concrete and dismantling of the conductor, and formwork and backfilling of the sinuses of the Foundation as follows. When dropping columns from top to bottom combine teeth-clamps with locking holes and closing the gap fix the column in the project position friction stud flanges.

After installation of the column space between the flanges and the top of Foundation fill with concrete to transfer part of the compressive effort on the concrete Foundation directly, which allows for the unloading of the inner conical shell and tapered frames. At the same time the lower part of the column is protected from corrosion.

During the operation of the Foundation of the columns is as follows. The compressive force is transmitted through the milled end of the flange on the outside about aspidella on the sole of the entire Foundation on the subgrade.

In the case of uneven settling of the pillars of their alignment is as follows: to the nozzles 10 attach the hoses from the pumps and pressure pumped them in plastic pulp, for example, of sand with the addition of plasticizer. Pulp presses reinforced concrete Foundation and column poddomkratit to the desired value.

In the case of uneven jacking the relevant part of the Foundation prigruzhajut controlroom.

The economic effect occurs due to the following:

1. Reduced metal consumption by 10-15%.

2. Reduced concrete consumption by 20-30%.

3. Reduced complexity of manufacturing and Assembly of the Foundation.

4. Ensured alignment of the Foundation to restore the normal operation of the building by non-uniform sediment columns.
