What are the types of scaffolding?
If you need to get to the mezzanine, it is enough to buy a stepladder, it can also be used for minor repairs. However, finishing on a large scale requires a better tooling, and if you feel that even goats will not help out, you should think about purchasing forests. In general, types of scaffolding are distinguished by the type of joint, the main types are 4 - wedge, clamp, frame and pin.
The easiest way to connect is a wedge, individual parts are fastened together by hammering a wedge on the crossbar or a diagonal spacer into a special lock on the vertical stand .
Very reliable wooden trunks construction tubular, however the fastening elements, those same pins, can be lost, which creates certain inconveniences. In fact, these are modular constructions, since not only horizontal and diagonal links with vertical posts but also sections with steps and decks are connected by pins.
Frame scaffolds are not very convenient for transportation, as the basis of them, as is clear from the name, is the finished frames joined by horizontal elements, along with the diagonal ones. But this makes it possible to use such demountable scaffolding for internal works. The most difficult at the stage of assembly are clamping woods, they use special pivoting clamps, which allow to give constructions quite arbitrary shape, up to hemispherical.
Collapsible scaffolds of the simplest construction
The pin constructions also have simplified modifications. In particular, it is easy to assemble a stand-alone structure in which the vertical elements of the gas pipes have 4 equidistant short tubes at the ends and at the center, intended for hooks welded to horizontal support links. Mount such mobile scaffolding can even a layman, who had never done anything similar before.
Often used for assembling scaffolding is a fastening element, such as a self-locking lock, which ensures high reliability of assembly by one person.
Very interesting is the option, like suspended scaffolding, however it is not for private use. Such structures are assembled from separate modules, which includes a protective grid, but are used in finishing works during the construction of high-rise buildings. They are fastened with special spacers to the technological visors and any possible protrusions, but are fed to the required level by a crane.
All these types are inventory scaffolds, that is, all of their parts are produced in factories and included in the complete sheet. Construction companies maintain a strict inventory of all the components of the .The direct opposite are constructions for which there are no ready-made elements, in particular - scaffolding, wooden. They can be built from a dozen boards, using fifty nails and an ordinary hammer with a naildriver. This option can also be considered simple, especially if you have basic carpentry skills.
Scaffolding on wheels and their features
When it is not possible to enclose the entire building with forests, and work is not carried out at a height of 100 meters, which, sometimes, frame structures, you can use a rather interesting option on a mobile platform or with wheels on racks. Outwardly, this design is very similar to the siege tower of the Middle Ages, only without plank or metal cladding, and with the mandatory addition in the form of brakes with rigid fixation. Called such a scaffolding on wheels is quite appropriate - a tower-tour.
Such free-standing structures can consist of several tiers, on which the platforms are laid or only from one platform at the top, in this case the height of the structure changes by removing the intermediate racks. However, there are more advanced forests, with sliding or scissor mechanisms, raising the platform along the limited pillars and connections to the "well".This type is much more expensive than conventional mobile scaffolding.
