The "Kislovodsk" Module
A closer look at the module "Kislovodsk" produced in our factory.
- THE PRICE OF THE READYMADE METAL STRUCTURES OF THE "KISLOVODSK" MODULE, DESIGN, INSTALLATION DIAGRAM AND WORKING PLAN IS 2 400 000 ROUBLES
- WE ALWAYS STOCK AT LEAST 75% OF THE TOTAL NUMBER OF LOAD-BEARING AND ROD ELEMENTS OF "KISLOVODSK" MODULE.
- WE NEED NO MORE THAN 3-5 DAYS TO SHIP TO THE CUSTOMER ONE SET OF READYMADE "KISLOVODSK" MODULE.
Single floor, single and multi-span
With suspended lifting and moving equipment with the height to the bottom of the structure of 4.8 m, 6.0 m, 7.2 m, 8.4 m
Located in I- IV wind and snow regions ( SNIP I I-6-74)
With designed ambient air temperature not lower than - 400C for heated and -300C for unheated facilities
With mildly aggressive environments.
The rod spatial lattice structure with plan dimensions of 30x30 m with a grid of columns 18x18 m, has an orthogonal belt basis with a cell of 3x3 m and a height of 2.12m on the belt axes. For connecting the rods into a spatial grid system a load-bearing element is used in the form of a steel polyhedron with threaded holes.
The threaded holes are oriented towards convergent load-bearing belts and braces. The facets of the load-bearing element are normal to the axes of the holes and equally located from the load-bearing center. In addition the load-bearing element has threaded holes for mounting the purlins, false ceilings and technological equipment.
The columns are the pillars made from the round steel pipes which have been rigidly embedded in the reinforced concrete foundation.
The tubular rod elements are made as per Group B from steel according to GOST 1050-74. The rods are 60x3; 76x3.5; 89x4; 102x4 in diameter and made of electric-welded pipes as per GOST 10704-63, the rods with diameter of 114x5; 127x7; 133x8 are made from hot-rolled pipes according to GOST 8732-70. The replacement of electric-welded pipes with the hot-rolled ones is permitted in exceptional cases with the appropriate feasibility study. The hexagon coupling material is per GOST 2879-69, the steel is of Grade 35 GOST 1050-74. The load-bearing elements are made of steel Grade 45 GOST 1050-74. The structures use bolts of the strength class 8.8, made of steel Grade 35X or 40X.
The structure is delivered disassembled into elements packed in the factory made containers. The assembly of the structural plate is made on the planned sites from the center to the periphery by the successive addition of elements. The assembly is made sequentially with ordinary mounting wrenches without the use of an extension.
The spacers are placed under the elements. The bolts for all the rods are screwed into the load-bearing elements as far as they will go. When the structure is lifted onto the columns the rigging must be done with the help of cross bars using the points, and pressure on the rods should be avoided.
In the most single-floor industrial buildings it is necessary to use the overhead beam cranes of varying capacity. The experience in designing of the «MARKHI» structures and the "Kislovodsk" modules show that they allow designing the overhead beam cranes up to 10 tf capacity. The typical structures of models ST-18.104.22.168, ST-18x12.3.4, ST-18x18.3.4 and ST-24x12.3.4 widely use the overhead beam cranes with the lifting capacity of 1.0 - 3.2 tf. In the cantilever structures the overhead beam cranes are located in the central spans of 18 m and 24 m. Besides, either a single beam crane or two beam cranes are being used. In all the cases, the overhead rails of the beam cranes are attached to the «MARKHI» structure through the smaller distribution beams, which are attached to the load bearing elements in the lower level of the spatial grid structure with the help of the high-strength bolts. The spacing of distribution of beams is 6.0 m, and in the case of the beam cranes with carrying capacity of more than 3.2 tf - 3.0 m. In order to design precisely the «MARKHI» structure with the consideration of the crane loads, their force has to be calculated by applying the concentrated forces from the beam crane to the attachment points in the grid structure.
