Flooring Clamp
A flooring clamp is a clamp (or cramp) for holding tongue and groove flooring in place while laying. Application A flooring clamp is used for holding tongue and groove flooring while individual boards are being face nailed. Up to 8 to 10 boards may be clamped at a time. A minimum of two are required; more is the norm. Spaced say every 4th or 5th joist. Placement The clamp is placed over a joist (range 35 mm to 65 mm thick), then its ratchet action handle is used to apply horizontal pressure on a sacrificial bearing board (100 mm x 50 mm) to hold the flooring boards true and in place for fastening.

Clamp (tool)
A clamp is a fastener, fastening device used to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. In the United Kingdom the term cramp is often used instead when the tool is for temporary use for positioning components during construction and woodworking; thus a C clamp, G cramp or a sash clamp but a wheel clamp or a surgical clamp. There are many types of clamps available for many different purposes. Some are temporary, as used to position components while fixing them together, others are intended to be permanent. In the field of animal husbandry, using a clamp to attach an animal to a stationary object is known as "rounded clamping." A physical clamp of this type is also used to refer to an obscure investment banking term, "fund clamps." Anything that performs the action of clamping may be called a clamp, so this gives rise to a wide variety of terms across many fields. Types Temporary These clamps (or cram ...

Tongue And Groove
Tongue and groove is a method of fitting similar objects together, edge to edge, used mainly with wood, in flooring, parquetry, panelling, and similar constructions. A strong joint, it allows two flat pieces to be joined strongly together to make a single flat surface. Before plywood became common, tongue-and-groove boards were also used for sheathing buildings and to construct concrete formwork. Each piece has a slot (the ''groove'' or '' dado'') cut all along one edge or along two adjacent edges, and a thin, deep ridge (the ''tongue'') on the opposite edge or edges. The tongue projects a little less than the depth of the groove. Two or more pieces thus fit together closely. The joint is not normally glued, as shrinkage would then pull the tongue off. The effect of wood shrinkage is concealed when the joint is beaded or otherwise moulded. In another assembly method, the pieces are end-matched. This method eliminates the need for mitre joints, face nailing, and the use of joi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OUP Oxford
Oxford University Press (OUP) is the publishing house of the University of Oxford. It is the largest university press in the world. Its first book was printed in Oxford in 1478, with the Press officially granted the legal right to print books by decree in 1586. It is the second-oldest university press after Cambridge University Press, which was founded in 1534. It is a department of the University of Oxford. It is governed by a group of 15 academics, the Delegates of the Press, appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho. For the last 400 years, OUP has focused primarily on the publication of pedagogical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joist
A joist is a horizontal structural member used in Framing (construction), framing to span an open space, often between Beam (structure), beams that subsequently transfer loads to vertical members. When incorporated into a floor framing system, joists serve to provide stiffness to the subfloor sheathing, allowing it to function as a horizontal Diaphragm (structural system), diaphragm. Joists are often doubled or tripled, placed side by side, where conditions warrant, such as where wall partitions require support. Joists are either made of wood, engineered wood, or steel, each of which has unique characteristics. Typically, wood joists have the Cross section (geometry), cross section of a Plank (wood), plank with the longer faces positioned vertically. However, engineered wood joists may have a cross section resembling the Roman capital letter ""; these joists are referred to as I-joist, -joists. Steel joists can take on various shapes, resembling the Roman capital letters "C", "", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ratchet (device)
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ''ratchet'' is also used informally to refer to a ratcheting socket wrench. __TOC__ Theory of operation A ratchet consists of a round gear or a linear rack with teeth, and a pivoting, spring-loaded finger called a '' pawl'' (or ''click'', in clocks and watches) that engages the teeth. The teeth are uniform but are usually asymmetrical, with each tooth having a moderate slope on one edge and a much steeper slope on the other edge. When the teeth are moving in the unrestricted (i.e. forward) direction, the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing it (often with an audible 'click') into the depression between the teeth as it passes the tip of each tooth. When the teeth move in the oppo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flooring
Flooring is the general term for a permanent covering of a floor, or for the work of installing such a floor covering. Floor covering is a term to generically describe any finish material applied over a floor structure to provide a walking surface. Both terms are used interchangeably but floor covering refers more to loose-laid materials. Materials almost always classified as flooring include carpet, laminate, tile, and vinyl. Subfloor The floor under the flooring is called the subfloor, which provides the support for the flooring. Special purpose subfloors like floating floors, raised floors or sprung floors may be laid upon another underlying subfloor which provides the structural strength. Subfloors that are below grade (underground) or ground level floors in buildings without basements typically have a concrete subfloor. Subfloors above grade (above ground) typically have a plywood subfloor. Flooring materials The choice of materials for floor covering is affected by ...

Floor Medallion
A floor medallion is generally a centerpiece of flooring design that can be made with various flooring materials, including natural stone, wood, metal, tile, glass or a variety of other materials suitable for flooring. The pattern can be created using various methods such as mosaic, intarsia, and marquetry Marquetry (also spelled as marqueterie; from the French ''marqueter'', to variegate) is the art and craft of applying pieces of wood veneer, veneer to a structure to form decorative patterns or designs. The technique may be applied to case furn .... With a mosaic, small pieces of flooring material are put together to develop a pattern. This can be done in a direct, indirect, or double indirect method. In the direct method small pieces are set directly into a bonding substrate like cement. Using an indirect method the pieces would be placed face down against paper or other material with a temporary adhesive. After the design is completed face down the entire section would b ...

Floor Vibration
In the design of floor systems in buildings vibrations caused by walking, dancing, mechanical equipment or other rhythmic excitation may cause an annoyance to the occupants or impede the function of sensitive equipment. A calculation procedure to analyze steel framed floor systems is given in a design guide published by the American Institute of Steel Construction. Enhanced or increased leasing activity in office buildings resulting in higher building occupancy has also been attributed to increased floor vibration. Modern concrete under-floors often specify a 3mm layer of sound-deadening material above (is it foam plastic like ethaline - something with a long-life since it will be expensive to replace). See also * Architectural acoustics Architectural acoustics (also known as building acoustics) is the science and engineering of achieving a good sound within a building and is a branch of acoustical engineering. The first application of modern scientific methods to ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthen Floor
An earthen floor, also called an adobe floor, is a floor made of dirt, raw earth, or other unworked ground materials. It is usually constructed, in modern times, with a mixture of sand, finely chopped straw and clay, mixed to a thickened consistency and spread with a trowel on a sub-surface such as concrete. Once dry, it is then usually saturated with several treatments of a drying oil. History Earthen floors were predominant in most houses until the mid 14th century in Europe, and persist to this day in many parts of the world. Frances Gies and Joseph Gies, Life in a Medieval Village In medieval times, almost all peasant housing had earthen floors, usually of hardpacked dirt topped off with a thin layer of straw for warmth and comfort. In China, most cottages and smaller houses also had earthen floors, made of rammed earth and sealed with raw linseed.Mitsu,Ahn , Developments in History: China Earthen floors were used in ancient Greece, and in many other countries in ancient t ...

Floors
A floor is the bottom surface of a room or vehicle. Floors vary from simple dirt in a cave to many layered surfaces made with modern technology. Floors may be stone, wood, bamboo, metal or any other material that can support the expected load. The levels of a building are often referred to as floors, although sometimes referred to as storeys. Floors typically consist of a subfloor for support and a floor covering used to give a good walking surface. In modern buildings the subfloor often has electrical wiring, plumbing, and other services built in. As floors must meet many needs, some essential to safety, floors are built to strict building codes in some regions. Special floor structures Where a special floor structure like a floating floor is laid upon another floor, both may be called subfloors. Special floor structures are used for a number of purposes: * Balcony, a platform projecting from a wall * Floating floor, normally for noise or vibration reduction * Glas ...
