Today we talk about fixing systems. How to choose the ones that best suit your needs? Let’s find out everything there is to know
Often and gladly you hear about anchors: well, this term corresponds very simply to a system of elements that have a decidedly important function, namely that of carrying out the transfer of stresses to the support material in which they have been inserted.
A fastening system, for example, can be created using an anchor rod and a particular chemical resin. In most cases, these are systems that are inserted into the masonry rather than the concrete.
In reference to these fasteners, here you can also turn to the web, a tool that is increasingly referred to in Italy. A well-known brand like Würth is able to offer its customers a wide and varied range of products, which can be used in any environment and with any type of material, as can be seen on the page https: //eshop.wuerth .it / Product-categories / Fasteners / 311435.cyid / 3114.cgid / en / IT / EUR /.
The fixing systems that can be found on the market
From a practical point of view, there are three important categories of anchors, that is those heavy, light and chemical. In reality, they are not the most appropriate terms, since the law calls them in other ways, but it can certainly be very important to get a better idea during the purchase phase.
Anchors can also be differentiated in chemical anchors and mechanical anchors and the latter are characterized by diversification in relation to operation, but also according to the construction material, which can be steel rather than a plastic material.
Another subdivision aspect that should be highlighted is the presence of structural anchors and non-structural anchors. The former must necessarily, according to the appropriate legislation, possess the CE marking, which one must always know how to recognize compared to the Chinese one, able to give greater guarantees, given that there is also talk of compliance with respect to some technical peculiarities provided for by law.
What are chemical anchors
When we talk about chemical anchors, we refer to fasteners that are formed from a resin in vials or cartridges, in the company of an anchor bar that is characterized by being ribbed or threaded, such as rebar.
In any case, the chemical anchor refers to two-component systems which include the resin, but also the catalyst. The latter, once it comes into contact with the resin, does nothing but stimulate a hardening process that allows you to activate the grip of the anchor.
For all the various fixings within the concrete, here is that the chemical anchor can become an excellent alternative solution, since the length that characterizes the threaded bar can vary considerably and all this offers the possibility of extending the depth level of the anchor to ensure a even higher degree of resistance.
The chemical anchor, however, can represent a decidedly effective solution also with regard to the masonry structure, which can be perforated or solid. With reference to mechanical anchors, however, in these cases, dowels made of nylon are used in most situations, but with lower capacities.
In the end, the chemical anchor, when associated with reinforcing iron, offers the possibility of avoiding having to deal with all those problems that frequently occur on construction sites. For example, the epoxy chemical anchor is characterized by being decidedly suitable both for the connections of concrete elements and casting joints.
In this sense, the best thing is to scan the market in search of a series of products that are able to provide a high level of resistance, which can be very useful on construction sites, especially due to a slow hardening process.
