the very first piece of precast prestressed concrete was produced by spancrete in 1946. , hollowcore is at home in virtually any building application that calls for strength, durability and speed of construction and is a crucial part of the structural integrity in multi-family residential, manufacturing and recreational facilities,,
precast concrete pier and deck slabs. extensive experience, precise manufacturing processes and cutting edge facilities allow us to craft superior marine precast concrete products, including pier and deck slabs. our catalog of precast pier, deck and related products include: floating docks. underwater infrastructure.
design guidelines for the use of full depth precast deck slabs used for new construction or for replacement of existing decks on bridges. this guideline has been reviewed and approved by the new england technical committee. several projects have already used these details and specification. if a state standard exists,
a simplified full-depth precast concrete deck panel system for accelerating bridge construction (abc) is introduced and a finite element analysis (fea) is conducted to investigate the static and dynamic , the concrete decks in the new system act as two-way slabs, instead of the one-way slab in the traditional system.
prestressed concrete panels have been used by the bridge construction industry in the state of texas for many years to increase construction speed , scale bridge deck was constructed that included precast panels at a 0o skew. the results indicated that the , bridge, deck, slab, shear, fatigue. 18. distribution statement.
apr 1, 2013 , the project's design-build team found the solution in bubbledeck, a new hollow-core slab technology that allows for extensive spans of floor and ceiling without typical column supports. although it was the first in california and one of the first in the united states to make use of bubbledeck technology, the,
3-sided box structures. short construction time. comprehensive design & support by oldcastle precast staff , voided slab. 18" depth voided slab is a full deck unit for spans from 27'-0" to 50'-0". they are 4'-0" nominal width. 26" depth voided slab is a full deck unit for spans from 42'-0" to 70'-0". they are 4'-0" nominal,
the tricon plank-deck™ bridge system consists of standardized precast concrete components; abutment/bent footings, riser sections and plank-deck slabs. the plank-deck elements incorporate the driving surface which means that no topping or wearing surface is required after installation. with the superstructure,
a fast-setting concrete mortar was placed between the slab and the stringer. railroads have also used precast elements in deck replacement programs. the atchison, topeka and. santa fe railway company has developed precast, prestressed deck slab construction standards for use in replacement of timber decks !]) •.
abstract. the majority of today's bridge decks are built using cast-in-place concrete construction. this is due to the perceived low initial cost and constructor familiarity with the system. this research report describes the design, details, and construction of an innovative full-depth precast concrete bridge deck system – the,

(nudeck) , construction of an innovative full-depth precast concrete bridge deck system – the second generation nudeck. (nebraska ,. 18.104.22.168 field engineering prior to slab installation .
the purpose of this paper is to discuss the construction and early performance of two 1999 – 2000 bridge deck replacement state contracts in illinois that included precast, prestressed concrete (ppc) deck planks. metal stay-in-place forms used in one of the contracts will also be briefly addressed in this report. in 1997, the,
apr 26, 2011 , precast full depth deck panels (fddp) may be used for new construction or for replacement of existing deck slabs. this guideline is not for use on partial depth precast deck panels that are intended to be overtopped with a reinforced concrete pour. please refer to additional guidance on partial depth deck,

the bubbledeck biaxial hollow precast concrete slab system is an unique system which radically improves building design & performance while reducing the. , building more with less bubble deck construction sdn bhd is the sole distributor of bubbledeck precast floor slab system for malaysia and,
composite slabs are an excellent choice when speed of construction is important. bundles of decking are lifted into place on the steel structure, for distribution by hand. the number of crane lifts needed, when compared with the precast alternative, is greatly reduced. the ability to stack the pieces of decking into bundles,
the filigree wideslab method is a process for construction of concrete floor decks from two interconnected concrete placements, one precast in a factory, and the other done in the field. the method was developed during the late 1960s by harry h. wise as a more efficient and economic construction process than,
experience has shown that the need to provide a small reinforced closure pours does not preclude the use of precast deck slabs for accelerated construction projects. high early strength concrete can be used to make this connection and the bridge can often be opened to traffic in less than one day. distribution direction.
apr 29, 2016 , utilized by designers of accelerated bridge construction. projects and by , minimum structural thickness of precast concrete deck. panels shall be 8". ,. must ensure the deck slab reinforcement adequacy at scupper. 4. if scupper is,
