Grouted – Wall Panel

Grouted base connections are a cost effective choice when design criteria will allow for their use. Grout tubes are filled with non-shrink grout (up to 10,000 psi required) prior to panel erection. Dowels protruding from precast are set into wet grout and panel is set at the correct elevation on shims.  Grouting under the base of the panel is completed after precast connections have been completed.

V-Pocket – Wall Panel

V-Pocket base connections are typically used when design connection performance does not allow for a grout tube connection.  V-pocket connection require a CIP embed to be installed in the foundation prior to precast installation.  Once panel is shimmed to correct elevation, steel tabs are welded between CIP embed and V-shaped precast embed to complete connection.  Access needs to be considered when using connection near columns or other site obstructions.

NMB – Wall Panel

NMB splice sleeves can be used in a variety of precast products that require a type 2 coupler. Rebar is constructed protruding from foundation and then cut to a specific distance above the foundation as required by size of NMB splice sleeve.  Female slice sleeve is embedded in precast and placed over protruding foundation rebar.  Once connection is complete at desired elevation, high strength mortar (that is provided solely by NMB manufacturer) is ejected into the sleeve via grouting tubes to complete connection.

NMB – Column

NMB splice sleeves can be used in a variety of precast products that require a type 2 coupler. Rebar is constructed protruding from foundation and then cut to a specific distance above the foundation as required by size of NMB splice sleeve.  Female slice sleeve is embedded in precast and placed over protruding foundation rebar.  Once connection is complete at desired elevation, high strength mortar (that is provided solely by NMB manufacturer) is ejected into the sleeve via grouting tubes to complete connection.

Gymnasium Roof

Gym roofs are often long spans due to the function of the structure and precast walls are used to carry these loads.  Recesses provided in the precast panel create a ledger for direct bearing of the beams.   Bolted connections can be designed once beam is shimmed to correct elevation.

Intermediate CIP Slab

When  required, intermediate conditions often include a connection from precast to CIP slab.  In this scenario, CIP embed design and location are coordinated and CIP embeds are installed onsite prior to precast installation per plan.  A combination of slotted angle welded to the CIP embed and directional inserts embedded in precast allow for required movement.

Roof Perimeter Beam

Often perimeter roof connections are completed to top of beam, bottom of beam or extending bent plate.  Design coordination between the provider of bent plate critical as bent plate is commonly supplied by steel manufacture prior to completion of connection design.  A combination of slotted angle welded to steel and directional inserts embedded in precast allow for required movement.

Column – Beam

Precast beams can have bearing on top of columns when required.  Splice couplers that extend a dowel up past top of column are typically used.  Inverted Tee beams that bear directly on column have corrugated grout tubes embedded to allow extended dowel to overlap.  Grout tubes are filled once beam (resting on bearing pads) is at correct elevation.

Wall Panel – DT

Pocket assemblies designed to hide connections can be used between Double Tee and Wall Panel assemblies.  Double Tee stem spacing = 6′-0″ and Maximum Double Tee width = 12′-0″.  Supporting wall panel layout is key and often is similar to Double Tee flange width to allow stems (and concentrated loads) to be centered in panel.

K-12/High Ed Design

 

Reduced Life Cycle Costs

Precast wall panels are a low maintenance, thermal efficient option that results in significant operating savings over the structure’s life span. Insulated wall panels can provide R-values up to 34 depending on the thickness and insulation type.

Precast Strength
Take advantage of the inherent load-bearing structural capacity of precast/prestressed products. Wall panels can resist roof and elevated floor loads and maximize the excellent span to depth ratio of precast beams/hollowcore, reducing the overall building height (plus conditioned space). Precast products can include prestressing, unlike products cast onsite, which optimizes design performance.

Attractive Appearance
Insulated wall panels can include mix designs with colors, interesting textures, form liners, and embedded thin brick for a clay appearance. Options for finishes are unlimited, and products are cast off-site in controlled environments.

Accelerated Schedule
Often K-12 projects are expansions to existing structure that often stay operational or require students to relocate during construction.  Faster completion means less impact on students and surrounding communities.
