The invention relates to the construction of buildings for industrial purposes, in particular to the building to accommodate chemical industries.

We know the rough-cut universal building to house chemical industries, including foundations and floor beam floor joists, walls, doorways, window frames, equipment, communications, control and instrumentation and control equipment Central bearing and placed on the sides of the vertical functional blocks that form on the outer contour of the building multifaceted prism [Kim NN. Industrial architecture. M: SI, 1988, s-189]. However, each block-box of the building is strictly functional, which does not allow to reconstruct it for other purposes, and the number of cases of space-planning the layout of units in the whole building is small, moreover, the construction of blocks and buildings in General does not create additional opportunity for the development of fire and explosion safety, energy efficiency and high environmental compatibility.

The closest technical solution to the claimed invention (the prototype) is building for chemical production. [Pat. Russia 2053338 C1 6, IN 5/00.] Building for chemical production is an axisymmetric many of the storey building to accommodate chemical industries. Geometrically, the building is a proper polyhedral prism, the number of faces of the prism may be different. Inside the prism is divided into blocks: Central bearing and vertical functional. The blocks are formed as a result of differentiation of the internal space of the building floor coverings with coating, inner bearing cylinder and radially directed from the cylinder wall partitions.

A disadvantage of the known building is the greater vulnerability of the upper and lower coverings and ceiling functional block than at the side walls, in case of an explosion inside the building.

The invention solves the problem of safety and environmental cleanliness when placing chemical industries.

The invention consists in that in the famous building, including the foundations and floor beam floor joists, walls, doorways, window flights, process equipment and control equipment Central bearing and a vertical functional blocks that form on the outer contour of the building multifaceted prism, the Central unit is made in the form of thick-walled concrete cylinder, where is the control equipment and instrumentation, and the OST is performance communications units installed around the perimeter of the cylinder coaxially with the last location of the lateral walls of the radial axes, passing from the center of the cylinder to the faces of the prism, with the formation of the raster form, and their premises, which is equipped with technological equipment provided with the premises of the Central unit through door openings made in the walls of the latter, the base and cover are made common to all blocks in the form of a bowl to collect respectively Straits and washes chemicals and precipitation, and the outer plane of the prism formed window frames, mounted between the beams and the ends of the side walls of the functional blocks, and in the ceilings and walls of functional blocks with holes of different configurations for skip communications, according to the invention the coating of the ceiling and floor functional blocks have a slope of not more than 5° to the ceiling in the directions of descent, respectively, of the outer box to the supporting cylinder and a bearing cylinder to the outer window.

Ha figure 1 presents a General view of the building; figure 2 - view of the building from the side; figure 3 is a covering of floors and ceilings of the building; figure 4 - key design parameters of the building.

Building for chemical production contains the top floor of building 1 (figure 1); bearing the Central cylinder 2 (Fig 1); the functional blocks 3 (figure 1); the Foundation 4 (figure 1); floor 5 (3); floor ceiling 6 (figure 3); the overlap of 7 (figure 3).

<> Building for chemical industries operates as follows.

The functional blocks 3 in the appropriate for a given chemical technology equipment processes chemical reactions, separation and purification, oil filling and packing of chemical products. Formed as a result of chemical transformations liquid medium is moved downward by gravity through piping along the trajectory helices, for mounting in which the radial and horizontal partitions 3 blocks during the construction of building structures made special mounting holes of different configurations for the pipelines connecting the apparatuses placed on the floors vertically and horizontally. Liquid and gas medium can be transported in compartments formed between the beams 7 and floor coverings 5 and the ceiling 6 at an angle less than 5°, specially located for this pipeline. In addition, in these niches are elements of the automatic fire extinguishing system, the composition of which is determined depending on the technological process (spray nozzles, tank with inert gas and so on). The staff in the functional blocks 3 is moved from the remote control inside of the cylinder 2 and back by the shortest route, not more than a radius of the building, by the time stay in the area is possible accidents will be minimal. When an explosion in the functional block 3, the inclined floor surface 5 and the ceiling 6 will create a reflective wave directed outward.

Thus, the proposed design of the building allows for comparison with prototype:

1) to minimise the potential devastating impact on the building, sending a blast wave on the walls and ceiling of tangent;

2) create a sealed cavity for communications and equipment in niches formed between the ceiling and the floor or ceiling;

3) to increase the illumination within the function block by increasing the reflectivity of the walls and floor coverings and ceiling;

4) create a slope to drain swabs and Straits in the functional blocks away from the Central cylinder.

Any liquid spilled on the floor of the functional unit 3 due to potential Strait, will flow in the direction of the slope with the bottom cover, where in the corner of the wall, it (the liquid) is collected for further processing or disposal.

The total number of premises can be determined by the formula

K=k1+k2

where k1=nm is the product of the number of sides (n) of the polygon by the number of floors of the inner cylinder (m);

k2=(m+1) - number of floors of the inner cylinder (m) plus one location on the roof of the building.

Key design parameters of the building are presented in figure 4.

Lu is l tilt coating 5 to the functional blocks of no more than 5° virtually no difficulties in transferring personnel. Hardware installation horizontally is provided by the difference of the heights of the pillars or special technology mounting of the equipment to the walls of the building.

The amount of the functional unit 3 can be determined by the formula

where D is the diameter of the inscribed in the polygon of the circle.

n is the number of sides of the polygon;

d1the external diameter of the supporting cylinder;

N - the maximum height of the functional block;

α is the angle of the floor coverings and ceiling.

Thus, the design of the proposed buildings for the chemical production ensures personnel safety, environmental compatibility and compactness.

The building to house the chemical industries, including foundations and floor beam floor joists, walls, doorways, window frames, process equipment and control equipment, bearing a Central and vertical functional blocks that form on the outer contour of the building multifaceted prism, the Central unit is made in the form of thick-walled concrete cylinder, where is the control equipment and instrumentation, and the remaining blocks are installed around the perimeter of the cylinder coaxially with the last location of the lateral walls of the radiation is Ino axes, passing from the center of the cylinder to the faces of the prism, with the formation of the raster form, and their premises, which is equipped with technological equipment provided with the premises of the Central unit through door openings made in the walls of the latter, the base and cover are made common to all blocks in the form of a bowl to collect respectively Straits and washes chemicals and precipitation, and the outer plane of the prism formed window frames, mounted between the beams and the ends of the side walls of the functional blocks, and in the ceilings and walls of functional blocks with holes of different configurations for skip communications, characterized in that the coating ceiling and floor of functional blocks have a slope of not more than 5° to the ceiling in the directions of descent, respectively, of the outer box to the supporting cylinder and a bearing cylinder to the outer box.
