Steel Fixer
A steel fixer (UK, ironworker or "rod buster" in the United States) is a tradesman who positions and secures steel reinforcing bars, also known as rebar, and steel mesh used in reinforced concrete on construction projects. The work involves following engineering drawings that detail the type of bar and the spacing used and setting out the work. The reinforcing bars are tied together with wire, which is cut using Pincers (tool), nips, or electric rebar tiers. Steel fixers are also responsible for attaching "spacers" and "chairs" that determine the amount of concrete cover.

Construction Worker
A construction worker is a person employed in the physical construction of the built environment and its infrastructure. Definitions By some definitions, construction workers may be engaged in manual labour as unskilled or semi-skilled workers. These workers begin by attending to general tasks such as digging, cleaning, and unloading equipment. As they gain more experience, they start to specialize in particular areas - for example, roofing, pipefitting, structural work, or carpentry. Over time, some opt to receive certification and undergo formal training to achieve qualifications and promotion. In other words, they may be skilled tradespeople, or they may be supervisory or managerial personnel. United Kingdom safety legislation has defined construction workers as people "who work for or under the control of a contractor on a construction site." In Canada, this can include people whose work includes ensuring conformance with building codes and regulations and those who supervi ...

Ironworker
An ironworker is a tradesman who works in the iron-working industry. Ironworkers assemble the structural framework in accordance with engineered drawings and install the metal support pieces for new buildings. They also repair and renovate old structures using reinforced concrete and steel. Ironworkers may work on factories, steel mills, and utility plants. [Baidu] |
Tradesman
A tradesperson or tradesman/tradeswoman is a skilled worker that specialises in a particular trade. Tradespeople (tradesmen/women) usually gain their skills through work experience, on-the-job training, an apprenticeship program or formal education. As opposed to a master craftsman or an artisan, a tradesperson (tradesman/tradeswoman) is not necessarily restricted to manual work. History In Victorian England, The terms "skilled worker," "craftsman," "artisan," and "tradesman" were used in senses that overlap. All describe people with specialized training in the skills needed for a particular kind of work. Some of them produced goods that they sold from their own premises (e.g. bootmakers, saddlers, hatmakers, jewelers, glassblowers); others (e.g. typesetters, bookbinders, wheelwrights) were employed to do one part of the production in a business that required a variety of skilled workers. Still others were factory hands who had become experts in some complex part of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rebar
Rebar (short for reinforcement bar or reinforcing bar), known when massed as reinforcing steel or steel reinforcement, is a tension device added to concrete to form ''reinforced concrete'' and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression, but has low tensile strength. Rebar usually consists of steel bars which significantly increase the tensile strength of the structure. Rebar surfaces feature a continuous series of ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage. The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with deformation patterns embossed into its surface. Steel and concrete have similar coefficients of thermal expansion, so a concrete structural member reinforced with steel will experience minimal differential stress as the temperature changes. Other readily available types of rebar are manufacture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinforced Concrete
Reinforced concrete, also called ferroconcrete or ferro-concrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (known as rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Construction
Construction are processes involved in delivering buildings, infrastructure, industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design that continues until the asset is built and ready for use. Construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or wikt:decommission, decommissioning. The construction industry contributes significantly to many countries' gross domestic products (Gross domestic product, GDP). Global expenditure on construction activities was about $4 trillion in 2012. In 2022, expenditure on the construction industry exceeded $11 trillion a year, equivalent to about 13 percent of global Gross domestic product, GDP. This spending was forecasted to rise to around $14.8 trillion in 2030. The construction industry promotes economic development and brings many non-monetary benefits to many cou ...

Engineering Drawing
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component. These drawings are linked together by a "master drawing." This "master drawing" is more commonly known as an assembly drawing. The assembly drawing gives the ''drawing numbers'' of the subsequent detailed components, quantities required, construction materials and possibly 3D images that can be used to locate individual items. Although mostly consisting of pictographic representations, Engineering drawing abbreviations and symbols, abbreviations and symbols are used for brevity and additional textual explanations may also be provided to convey the necessary information. The process of producing engineering drawings is often referred to as technical drawing or drafting ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pincers (tool)
Pincers are a hand tool used in many situations where a mechanical advantage is required to pinch, cutting, cut or pull an object. Pincers are first-class levers, but differ from pliers in that the concentration of force is either to a point, or to an edge perpendicular to the length of the tool. This allows pincers to be brought close to a surface, which is often required when working with Nail (fastener), nails. Pincers are primarily used for removing objects (typically Nail (fastener), nails) out of a material that they have been previously applied to. Carpenter's pincers are particularly suited to these tasks. Sharpened pincers are also used to cut away natural calluses, also called Chestnut (horse anatomy), chestnuts, from a horses body. Further use of pincers is the trimming of the edges of horses hoofs. If the pincers have perpendicular cutting edges, the pincers are often called end-nippers or end-cutters. They're often used in jewelry making, for trimming flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete Cover
Concrete cover, in reinforced concrete, is the least distance between the surface of embedded reinforcement and the outer surface of the concrete ( ACI 130). The concrete cover depth can be measured with a cover meter. The purpose of concrete cover is to protect the reinforcement from corrosion, fire, and other potential damage. The required concrete cover depends on several factors, including the environmental conditions to which the structure will be exposed, the size of the reinforcing steel, the concrete strength, and the type of structure being constructed. Generally, larger diameter reinforcement bars require more concrete cover than smaller ones. In most cases, local building codes and engineering standards specify the minimum required concrete cover for various types of structures. It is important to adhere to these requirements to ensure the safety and longevity of the structure. Purpose of provision of concrete cover The concrete cover must have a minimum thickness for ...

Apprenticeship
Apprenticeship is a system for training a potential new practitioners of a trade or profession with on-the-job training and often some accompanying study. Apprenticeships may also enable practitioners to gain a license to practice in a regulated occupation. Most of their training is done while working for an employer who helps the apprentices learn their trade or profession, in exchange for their continued labor for an agreed period after they have achieved measurable competencies. Apprenticeship lengths vary significantly across sectors, professions, roles and cultures. In some cases, people who successfully complete an apprenticeship can reach the " journeyman" or professional certification level of competence. In other cases, they can be offered a permanent job at the company that provided the placement. Although the formal boundaries and terminology of the apprentice/journeyman/master system often do not extend outside guilds and trade unions, the concept of on-the-job trai ...

Vocational Training
Vocational education is education that prepares people for a Skilled worker, skilled craft. Vocational education can also be seen as that type of education given to an individual to prepare that individual to be gainfully employed or self employed with requisite skill. Vocational education is known by a variety of names, depending on the country concerned, including career and technical education, or acronyms such as TVET (technical and vocational education and training; used by UNESCO) and technical and further education, TAFE (technical and further education). TVE refers to all forms and levels of education which provide knowledge and skills related to occupations in various sectors of economic and social life through Formal learning, formal, Nonformal learning, non-formal and informal learning methods in both school-based and work-based learning contexts. To achieve its aims and purposes, TVE focuses on the learning and mastery of specialized techniques and the scientific p ...
