Advantages

This is ensured by the use of elements of maximum unification and high factory readiness.

The wide range of DoorHan products allows you to equip any construction site with all the necessary equipment (gates, technical and refrigeration doors, loading equipment, stained glass structures, etc.)

The lattice structure of the trusses allows you to lay utility networks in the body of the structure, which makes it possible to compactly and quickly carry out all the necessary communications without taking up additional space.

The lattice structure of the building's truss structures makes it possible to optimize the amount of metal used in construction.

The connection scheme of columns and trusses allows the use of such a structure in buildings up to the II degree of fire resistance without additional protection of metal structural trusses. Only metal columns of the frame are subject to fire protection.

Thanks to the design scheme and the low weight of the building frame, the consumption of materials for foundations is minimized.

1. Buildings and structures based on a metal frame must be systematically maintained in order to prevent the destructive effects of atmospheric, climatic and man-made factors.

2. It is necessary to timely carry out a set of operations to maintain the serviceability and serviceability of buildings, their individual parts and structural elements.

3. During the operation, maintenance, technological re-equipment and repair of a building or structure based on a metal frame, it is prohibited to change their design solutions, to carry out work to strengthen building structures without a design or agreement with a design organization or other specialized organization.

4. It is prohibited to make changes that affect the load-bearing capacity of structures without agreement with the design organization.

5. It is necessary to comply with the operating conditions of individual building components: external steel doors, gates, plastic windows. When operating, follow the manufacturer's instructions.

6. It is necessary to carry out regular maintenance of the roof of the building: clear snow from the roof, clean gutters, drain funnels and drainpipes.

7. To prevent icing of the drainage system, it is recommended to install heating cables in gutters and pipes.

8. During periods of heavy snowfall, regularly check the amount of snow on the roof. If the weight of snow cover on the roof exceeds the values given in the regulatory documents of the Russian Federation, immediately clear the roof of snow.

. Buildings can be operated at temperatures from -55 to +55 °C.

10. When operating buildings, it is necessary to comply with fire safety rules.

Additional Information print

1. The frame of the building is designed in the form of a load-bearing single-span or multi-span steel frame made of tubular cross-section rafter/sub-rafter trusses. Rafter trusses are designed from pipes of rectangular and square sections supported on the upper chord. The support of the trusses on the columns is hinged. Welded rafter beams are installed at the ends of the building, supported by end posts. The rigidity of the end walls is ensured by a system of vertical braces and struts.

2. The roof and wall purlins are made according to a split pattern from bent galvanized C-shaped profiles. The density of the zinc coating is 275 g/m². The pitch of the roof purlins is determined during the design process.

3. The stability and geometric immutability of the building is ensured:
- in the transverse direction - by the own rigidity of the columns clamped into the foundation,
- in the longitudinal direction - by a system of vertical connections and struts.
The rigidity of the coating is ensured by a system of horizontal connections and struts.
Horizontal and vertical connections along the frame and half-timbering are made of flexible round steel with pre-tensioning or from rolled profiles without pre-tensioning.

4. All factory connections are welded. Mounting connections with regular bolts and high-strength bolts.

5. Frame coating: primer-enamel red-brown (RAL 8012) or light gray (RAL 7035) in two layers. The total thickness of the coating is 80 microns.

Element-by-element installation

Installation in enlarged blocks

Prepare storage areas for elements of a complete building.
Provide the construction site with the machinery and equipment necessary to carry out the installation of a complete building.
Perform the necessary zero cycle work.
Extend the building axes to the terrain.
Pour the foundations under the supporting frame and install the anchor bolts in the design position.
Carry out a geodetic survey of the top of the foundations and determine possible deviations in the position of the anchor bolts from the design one.
The results of geodetic survey should be formalized properly.
If there are deviations in the position of the anchor bolts from the design, send information to the design department of the DoorHan concern to make a decision on the subsequent installation of structures.
Foundations must be designed in such a way as to absorb all the necessary loads from the load-bearing and enclosing structures of a complete building.
Deviations of the position of the axes of the object under construction from the design ones are not allowed.
Deviations of the position of anchor bolts from the design are allowed no more than 3 mm.
When carrying out installation work, it is necessary to comply with safety requirements.
