Laborer
A laborer ( or labourer) is a person who works in manual labor typed within the construction industry. There is a generic factory laborer which is defined separately as a factory worker. Laborers are in a working class of wage-earners in which their only possession of significant material value is their labor. Industries employing laborers include building things such as roads, road paving, buildings, bridges, tunnels, pipelines civil and industrial, and railway tracks. Laborers work with blasting tools, hand tools, power tools, air tools, and small heavy equipment, and act as assistants to tradesmen as well such as operators or cement masons. The 1st century BC engineer Vitruvius writes that a good crew of laborers is just as valuable as any other aspect of construction. Other than the addition of pneumatics, laborer practices have changed little. With the introduction of field technologies, the laborers have been quick to adapt to the use of this technology as being ...

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 ...

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 ...

Hammer
A hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nail (fastener), nails into wood, to shape metal (as with a forge), or to crush Rock (geology), rock. Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. Traditional disciplines include carpentry, blacksmithing, war hammer, warfare, and mallet percussion, percussive musicianship (as with a gong). Hammering is use of a hammer in its strike capacity, as opposed to pry bar, prying with a secondary claw or grappling with a secondary hook. Carpentry and blacksmithing hammers are generally wielded from a stationary stance against a stationary target as gripped and propelled with one arm, in a lengthy downward plane (geometry), planar arc—downward to add kinetic energy to the impact—pivoting mainly around the shoulder and elbo ...

Safety Equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canteen (bottle)
A canteen is a reusable drinking water bottle designed to be used by hikers, campers, soldiers, bush firefighters, and workers in the field. It is usually fitted with a shoulder strap or means for fastening it to a belt, and may be covered with a cloth bag and padding to protect the bottle and insulate the contents. If the padding is soaked with water, evaporative cooling can help keep the contents of the bottle cool. Many canteens also include a nested canteen cup. Primitive canteens were sometimes made of hollowed-out gourds, such as a calabash, or were bags made of leather. Later, canteens consisted of a glass bottle in a woven basket cover. The bottle was usually closed with a cork stopper. Designs of the mid-1900s were made of metal – tin-plated steel, stainless steel or aluminum – with a screw cap, the cap frequently being secured to the bottle neck with a short chain or strap to prevent loosening. These were an improvement over glass bottles, but w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Five Gallon Bucket
The five-gallon bucket, also known as an 18-liter bucket or a 20-liter bucket, is a common bucket size in the United States and Canada, with a liquid capacity of 5 gallons (18.93L). History In the 1960s, buckets were generally made out of metal. In 1967, William Roper, an owner of a plastic-molding company based in Los Angeles, introduced a plastic pail with a lid, creating one of the first five-gallon buckets as a result. At the end of the 20th century, around 170 million five-gallon buckets were produced annually in the United States and Canada. The annual revenue generated from the selling of five-gallon buckets was $350 million. Design The buckets are typically fourteen inches tall, with a diameter of twelve inches. A wire or plastic handle is usually attached to the top three inches. Five-gallon buckets are usually designed to be nested within in each for storage. Plastic buckets have more uses due to the popularity of plastic for food products and the tendency of metal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soapstone
Soapstone (also known as steatite or soaprock) is a talc-schist, which is a type of metamorphic rock. It is composed largely of the magnesium-rich mineral talc. It is produced by dynamothermal metamorphism and metasomatism, which occur in subduction zones, changing rocks by heat and pressure, with influx of fluids but without melting. It has been a carving medium for thousands of years. Terminology The definitions of the terms "steatite" and "soapstone" vary with the field of study. In geology, steatite is a rock that is, to a very large extent, composed of talc. The mining industry defines steatite as a high-purity talc rock that is suitable for the manufacturing of, for example, insulators; the lesser grades of the mineral can be called simply "talc rock". Steatite can be used both in lumps ("block steatite", "lava steatite", "lava grade talc"), and in the ground form. While the geologists logically will use "steatite" to designate both forms, in the industry, "steatite" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masonry Trowel
The masonry trowel is a hand trowel used in brickwork or stonework for levelling, spreading and shaping Mortar (masonry), mortar or concrete. They come in several shapes and sizes depending on the task. The following is a list of the more common masonry trowels: *Brick trowel: or mason's trowel is a point-nosed trowel for spreading mortar on bricks or concrete blocks with a technique called "buttering". The shape of the blade allows for very precise control of mortar placement. *Bucket trowel: a wide-bladed tool for scooping mortar from a bucket; it is also good for buttering bricks and smoothing mortar. *Concrete finishing trowel: is used to smooth a surface after the concrete has begun to set; it is held nearly level to the surface of the concrete, and moved with a sweeping arc across the surface. *Corner trowel: used for shaping concrete around internal or external corners; the handle is located at the center of a 90° bend in the blade for balance and the ability to apply ev ...

Screwdriver
A screwdriver is a tool, manual or powered, used for turning screws. Description A typical simple screwdriver has a handle and a shaft, ending in a tip the user puts into the screw head before turning the handle. This form of the screwdriver has been replaced in many workplaces and homes with a more modern and versatile tool, a power drill, as they are quicker, easier, and can also drill holes. The shaft is usually made of tough steel to resist bending or twisting. The tip may be hardened to resist wear, treated with a dark tip coating for improved visual contrast between tip and screw—or ridged or treated for additional "grip". Handles are typically wood, metal, or plastic and usually hexagonal, square, or oval in cross-section to improve grip and prevent the tool from rolling when set down. Some manual screwdrivers have interchangeable tips that fit into a socket on the end of the shaft and are held in mechanically or magnetically. These often have a hollow handle that ...

Adjustable Spanner
An adjustable spanner (UK and most other Anglophone countries), also called a shifting spanner (Australia and New Zealand) or adjustable wrench (US and Canada), is any of various styles of wrench, spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut (hardware), nut, screw, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner. Forms and names There are many forms of adjustable spanners; many of them are screw thread, screw-adjusted, whereas others use levers, and some early ones used wedges. The early taper-locking spanners needed a hammer to set the movable jaw to the size of the nut. The modern screw-adjusted spanner and lever types are easily and quickly adjusted. Some adjustable spanners automatically adjust to the size of the nut, using a motor and battery. Simpler models use a serrated edge to lock the movable jaw to size, while more sophisticated versions are digital types that use sheets or ...
