farm looks. The shape and dimensions of the truss are controlled by rods and pipes that fit in the right order and create the necessary base. Round pipes help deftly distribute all parts of the structure and balance the costs of construction. Metal beams, in turn, are more expensive and impractical in installation.

Each new farm must consist of the top level( including the roof), the lower level( including the foundation) and the laths between them. There is a certain terminology relating to this type of structure: the distance between the posts and the braces is called the panel, and between the pillars of the battens are spans. Farms are divided by type of level and purpose.

The purpose of the farm is as follows:

  1. For the
  2. bridge For the
  3. truss mount For the
  4. trestle For moving the

equipment According to the levels can be:

  1. In the form of an arch
  2. In the form of a triangle
  3. In the form of the
  4. polygon Parallel

The most common is that triangularform, because it is built easier than other types. For a level constantly influenced by various factors, additional racks and fasteners can be installed.

Taking into account the number of racks and the total area, the attachments can be divided into heavy and light, conventional, combined and with effort. Connect all parts of the farm mainly with special paired corners. When using other corners, the resulting design will be less rigid and reliable, and therefore, can withstand less during operation. To fix the rods, use the slits.

The tubular method in the construction of the trusses will allow to forget about corrosion, however it is difficult to fix all the pipe elements.

Rigid system of metal structures

Classification of roofing systems

The rafters can be classified according to the load.

  1. System with only its own weight, roof weight and roofing material
  2. System with atmospheric precipitation load and other
  3. System with other loads

09 Metalware farms-Fig.255-4 Calculation of system loads

When calculating the weight of the roof, the coating material and its weight, it is understood that all these components pressurize the building. Trips in the farms are different, but the most important thing is to protect the structure from snow on the roof.

The rod load is calculated in accordance with the diagrams in which all the supports and the step between them are prescribed. Especially this concerns a farm with a slope.

When the total load factor is taken into account, the force is distributed exactly at the support points. Also, you understand that thanks to the use of metal fasteners, the entire structure and its rigidity will only be strengthened. Sustainability is determined throughout the territory of the structure, and shortcomings are corrected by additional fasteners.

If you screw in tensioned rods resistance to loads causes a sagging on the total weight of the structure. The flexibility of the structure depends on the length of the fasteners. To increase it, you need to set up linking elements between the levels of the farm. The design will be built more stably if you use the shoe, which is supplied with the spacer.

Latticed structures: application of

Latticework is commonly used for gyms and other public places, such as stations, pavilions, markets. In addition, lattice farms are used for the construction of hangars to accommodate the overall mechanisms due to the fact that their structures are very strong and able to cope with heavy loads.

Creation of the project includes all the nuances of construction and location of the building. Optimum functioning of a large-sized building is possible only with a correct calculation of the placement of racks, levels and crates.

Important! In o , the structure of the structures with the arrangement of levels along the parallel is made only by a triangular crate, for which the height should be the same as the span. Farms are very high, they can not be disassembled into components, therefore they can not be transported by railway means. To connect the structure, the welding equipment and threads o are used.

A colorful example of the use of lattice constructions is the well-known Eiffel Tower in Paris.

It is possible to carry out a preliminary load test for the structure, using strong and reliable materials for this. This will allow to check the building for durability and promote the expansion of the range of use of the material, which will allow to regulate the received loads.

Types of constructions

The structures are divided into such types with specific characteristics inherent to them and affecting the service life:

  • The first view is to use them in loaded places and to remove the load from the busiest sections of the
  • . The second view is toApply them to the entire space and its individual parts, which are most vulnerable to the stress of individual supports. This kind is better than the first, because it allows you to evenly distribute the load depending on the material of the elements.

. In summary, it is worth noting that the installation of pipes and the preparation for the truss pipes is not an easy task, requiring the ability to build and design.
