Abstract

The invention relates to frameworks of one-story industrial buildings. The purpose of the invention is to reduce material consumption by improving the static framework scheme. The frame columns are installed on the foundations with the combination of the upper edge of the outer face with the center axis of the frame and displacement of the outer face of the column inside the building at the level of the upper edge of the foundation by the magnitude of the eccentricity of the resulting force from the crane and static loads. 1 il.

The invention relates to the construction, in particular to the industrial framework you

buildings with columns of continuous section, such as workshops of factories, crane racks of warehouses, machinery halls and other structures in which the crane load acting on the columns significantly exceeds the permanent loads from the structures of buildings

The purpose of the invention is to reduce material consumption by improving the static framework scheme.

The drawing shows a fragment of the frame of a single-storey industrial building.

The framework of a single-storey industrial building consists of foundations and columns 2 with a console 3 for accommodating crane girders (conventionally not shown) „

Columns 2 are installed on foundations 1 with the combination of the upper edge 4 of its outer face 5 with the split axis 6 of the frame and with the displacement of their outer face 5 inside the building at the level of the upper edge 7 of foundation 1 by the value of eccentricity e of the effective force P from the impact on the column 2 static P and crane P loads.

In this case, the geometric axis 8 of the column 2 intersects the geometric axis 9 of the foundation 1 at the level of its upper edge 7.

The crane load P from the bridge crane and the static load P from the building covering, applied to the eccentricity column 2, respectively, e and e ,.

This moment is a negative factor, as it leads to an increased consumption of materials for foundations 1 and columns 2,

When the column 2 is displaced at the level of the upper edge 7 of the foundation 1 inside the building by an eccentricity value e, the moment becomes equal to zero, since the resultant force P passes through the intersection point of the geometric axis 8 of the column 2 and the axis 9 of the foundation 1 at the level of its upper edge 7, provides the application of the resultant force P along the geometrical axis 9 of the foundation 1.

For walling made of steel profiled sheet (in the case where the span with the overhead crane is extreme), the pitch of the columns does not affect their attachment. Wall fences made of heavy materials (reinforced concrete panels, blocks, bricks) should be self-supporting and should be installed on the fundamental beams located at a distance from the columns that are equal to the eccentricity e.

Invention Formula The framework of a single-storey industrial building, including foundations and columns, mounted on the latter with the combination of the upper edge of their outer face with the center axis of the frame and made with a console for supporting the crane beam, is characterized in that, in order to reduce material intensity by improving the static scheme of the frame, The columns are installed with the displacement of their outer face inside the building at the level of the upper edge of the basement by the amount of the eccentricity of the resultant force from crane and static loads.
