Ducts for air pollution control in a 17000 standard cubic feet per minute regenerative thermal oxidizer (RTO). A round galvanized steel duct connecting to a typical diffuser Fire-resistance rated mechanical shaft with HVAC sheet metal ducting and copper piping, as well as "HOW" (Head-Of-Wall) joint between top of concrete block wall and underside of concrete slab, firestopped with ceramic ...
A reducer reduces the pipe size from a larger to a smaller bore (inner diameter). Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. [15] This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The reduction length is usually equal to the ...
Power screeds can be powered by gas, electricity or hydraulics. [citation needed] In concrete, prior to the mix drying, the concrete should be smoothed out on the desired surface. The compaction performance of the power concrete screed is mainly determined by the centrifugal force of the vibration force and only to a minor extent by the static ...
Riser Clamp holding plastic pipe, penetrating through a concrete floor slab. The copper pipe penetration is firestopped with firestop mortar. Riser clamp for a standpipe through-penetration firestop inside a fire hose cabinet under construction
The drainage of the joint is via the drainage system of the bridge deck. Certain joints feature so-called “sinus plates” on their surface, which reduce noise from over-passing traffic by up to 80%. [2] Masonry control joints are also sometimes used in bridge slabs.
By reducing the weight of the slab without compromising its structural strength, it is possible to create a thicker slab to support more weight over a longer span. Hollow-core slabs , also known as voided slabs, initially appeared as one-way elements in Europe during the 1950s, and are still commonly manufactured in precast form for ...
A spectacular year awaits, Taurus!According to Thomas' predictions, 2025 is going to bring forth many "surprises and fresh starts" your way. If the past few years have seemed like a whirlwind ...
Diamond grinding is a pavement preservation technique that corrects a variety of surface imperfections on both concrete and asphalt concrete pavements. Most often utilized on concrete pavement, diamond grinding is typically performed in conjunction with other concrete pavement preservation (CPP) techniques such as road slab stabilization, full- and partial-depth repair, dowel bar retrofit ...
