The natural or synthetic rubber exterior of the joint which protects the carcass from damage. As far as types of metal expansion joints, choose from simple bellows, controlled-flexing, universal style, pressure balanced, hinged, gimbaled, externally pressurized, rectangular, or flexible V-Loops constructed using flexible metal hose (see our Products for HVAC web section for additional information), In addition, we offer a complete assortment of pipe alignment guides and can assist with determining their required number and placement. Good tolerance to chemicals and heavier transit, therefore ideal for porcelain stoneware tile in...... covering material. Cutting in expansion joints requires additional work and expense, especially if it is against a wall or other structural component. Concrete expands and contracts with temperature and moisture changes. 7 mm) spaced at frequent intervals offer greater control than thicker joints spaced at greater intervals. Our familiarity stems from having seen them in large buildings, sidewalks, malls, or when driving on concrete roads or bridges. The small stake slot found at each end will allow a stake to double as a butt splice. Unisource V-Loops are an ideal option for compensating for thermal pipe growth. There are two basic strategies to control cracking for good overall structural behavior. 300% Swelling Expansion Concrete Joint Waterproof Sealing Bentonite Water Stop Strips 20*30mm. While concrete is very strong in compression the tensile strength is only 8 to 12 percent of the compressive strength.

Sweets is meant to be the most comprehensive and useful tool for finding building products information. Expansion cracks are used to control thermal expansion and movement by other forces to prevent the concrete buckling or breaking. Contraction/Control Joints. However, much depends on location and indoor versus outdoor use, as temperature plays a large role in the occurrence of cracks. Bridge expansion joints keep different pours, slabs, or structures level where they meet to prevent trip hazards or traffic bumps. They are typically cut into the concrete surface using a grooving tool during the screeding or finishing stage as the concrete sets up. Expansion Joint Covers are durable and effective surface-mounted metal covers anchored to one concrete slab either floor or wall that allows lateral movement. Its design,... Novojunta Pro® Metal 30 is a system of profiles made entirely of natural aluminum to be placed in expansion joints up to 30 mm width. With using Flexi Aluminium joint... Possible movement: 50 mm. The removable cap measures 3/8" x 3/8" and is manufactured of PVC compound. In rare situations, an expansion joint may be cut through the concrete using a heavy-duty wet-cut concrete saw.

Metal Keyway Expansion Joints Concrete

Unisource V-Loops can perform the functions of large pipe loops or expansion joints, and in addition, can provide protection and flexibility in multiple planes during potentially catastrophic earthquakes. Special bellows material would include 316SS, 321SS, Inc 600, and Inc 625. Control joint spacing often is based on the thickness and size of the pour. Unguided piping, under pressure will tend to buckle, sometimes severely. An elbow style expansion joint designed for applications involving 90 degree change of direction and situations where main anchors cannot be placed in the system. Stainless Steel 304 / Polished. Please contact our highly trained customer service representatives to assist you in finding the optimal expansion joint design for your application. The tops of these rings will begin to make contact when the bellows are compressed, spreading the movement equally over each convolution. The joint goes all the way through the structural component and is commonly 1/4" to 1" wide, but can be up to 20" wide. Product may be cut on jobsite to exact size required.

Location of Construction Joints in Concrete Slabs. Stainless steel expansion joints are a type of metal bellows that are often used in construction projects to help relieve the stress that regular movement places on building materials. FIBRE LITE is a unique, light-duty forming material and expansion joint. Strong fixed points and good axial pipe guides required. Since Unisource V-Loops do not impose thrust forces on the pipe system, a minimum of guiding is required. These joints can be...... recess mounted floor joint covers for tamperproof applications where low maintenance is also required. Suggested floor bays: 16m2. It is usually cut 1/4 of the way through a slab within 18 hours of the pour. The carcass of the joint between the arch is usually supported by metal rings or wire to resist pressure.

When fluoroplastics are used in rubber expansion joints this results in better thermal stability, low friction and resistance to corrosive fluids, chemicals, abrasion and erosion. Due to their resistance to corrosion and wear, the profiles are ideal for resin-based terrazzo and natural stone tile layings. It is able to take up large expansion and contraction movements, as well as vertical shearing movements, and is also suitable for all types of finish: concrete, screed, tiling, etc. Joints may be tooled into the surface (first pass) prior to the onset of bleeding or immediately with the first pass of the floating operation. Flexible pipe joints, expansion bellows and pipe connectors help solve piping system issues including misalignment; vibration; stresses from thermal expansion and contraction; noise dampening; shock from water hammer, pressure spikes and pump cavitation; and save space compared to loops and bends. Unlike large pipe loops, Unisource V-Loops take up a minimum of space, providing pipe motion accommodation solutions in limited space situations such as indoor piping. PRO-KEY™ is a stay in place metal keyed control joint former for use in concrete flatwork as a control or construction joint. The basic concept is to provide ample room for the concrete to expand and contract without creating damaging stresses and resultant cracking. If there are no expansion joints, concrete will crack wherever it chooses. Joint variants may also incorporate lateral offset features or reducer connections to connect pipework of unequal diameters up to a recommended 20-degree reduction along the length of the joint. Pressure Balanced Expansion Joints. With elevation checked by instrument, stretch a line the length of the joint below the finished elevation.
