Construction of houses involves the construction of the foundation of the building, so they build different designs of foundations. Depending on the material from which the house is built, one or another type of foundation is suitable. One of the main elements of the base is the reinforcement strapping, which gives strength and flexibility to the concrete structure. The most common of the metal rods for the foundation is 12 mm reinforcement. It is impossible to underestimate the size, because this indicator is already the minimum. Before you engage in formwork and foundation pouring, it is necessary to calculate the number of metal products that need to be delivered to the facility. In this regard, the question arises: how much does a meter of rebar weigh 12 mm?
Types of metal rods for the foundation
Reinforcing metal is manufactured in accordance with GOST, which is a regulatory legal act of the Russian Federation and obliges manufacturers and developersadhere to the required parameters that are specified in the document. To determine how much a meter of reinforcement-12 weighs, you need to know what types of products are produced. There is hot-rolled steel with 6 strength classes, steel thermomechanically hardened, welded steel and composite polymer reinforcement. The latter is the lightest of all the rest, if we take the same diameter for comparison, because it is made of a special lightweight material.
How to calculate weight
To determine how much rebar-12 is in a ton, three methods are used. First, one or more rods of the same diameter and a certain length can be weighed. After that, divide the ton by the result of the weight and calculate the amount. The second option is designed to be used in the calculations of the nominal diameter of the product, which is equal to the size of the cross section of a smooth rod. The third way to solve a simple problem of how much a meter of rebar-12 weighs is to use tables with standard technical indicators to determine the weight according to the diameter of the metal product. Such data are determined by GOST, thanks to which you can quickly find out the amount per ton, based on the type, type of product, and also taking into account the material used for manufacturing.
Using GOST in calculations
Metal bars can be smooth or grooved. With the first, the situation is simpler, because the diameter is the same throughout the entire length of the product. corrugated, inunlike them, they have a non-uniform surface, which makes it difficult to calculate their weight. The regulatory document contains different tables with the definition of the diameter of the rod, its weight depending on the strength class, the metal used, the hardening process, rolling, etc. As a result, in order to find out how much a meter of reinforcement-12 weighs, it is necessary, in addition to the diameter, to take into account some indicators. GOST indicates that a product with a diameter of 12 mm has a minimum diameter between the ribs of 11 mm, and a maximum diameter on the rib is 13.5 mm. Based on these indicators, the estimated area of \u200b\u200bthis product has already been worked out, which is 1.13 cm2. Further summed up and it turns out that the running meter 12 of the reinforcement has a weight of 0.89 kg. It turns out that in 1 ton of rolled metal to create a strong, reliable foundation, 1123, 60 pieces of meter-long bars fit. If 12 mm reinforcement is not used, but a larger diameter is taken, then the number of rods, respectively, becomes smaller.
Why do we need such calculations
Design and construction are major steps in creating a safe home and the people living there. Calculations become necessary so that every step at the construction site is accurate and correct. The amount of necessary reinforcement is needed to calculate the strength of the foundation and will allow delivery to the construction site by specialized transport in the required quantity. And this will at least reduce the cost of transportation, loading, and reduce labor costs. Therefore, any, even small constructionshould involve advance design and calculation of the required material. This is not only about fittings, this rule applies to any type of building materials, whether it be brick, block, wood or even linoleum, laminate, wallpaper. Everything has an account, because for every centimeter, kilogram today you have to pay.
