Choose applicable bracketed items(s) or insert appropriate information.Remove information and/or requirements not related to the respective project, whether or not brackets are present.Comments and suggestions on this guide specification are

12、OTE: This specification does not include the floor upon which the elevated floor is superimposed, except to define the nature and condition of the supporting floor.Access flooring systems include floor panels, pedestals and items such as stringers, steps, ramps, closures and trim. Access flooring sy
13、stems must be designed to accommodate static, rolling and impact loadings.None of the mechanical and electrical services essential to the operation of equipment are included. Coordinate with mechanical and electrical SECTION 09 69 13 Page 3Provided by IHSNot for ResaleNo reproduction or networking p

Drawings must indicate location and limits of the flooring systems, finish floor elevation, panel size, type, f
15、inish and anti-static provisions, colors, pedestal mounting and subfloor connection system details.STRINGERLESS ACCESS FLOORING is covered in SECTION 09 69 19.Stair and/or ramp information, such as tread width and riser height for stairs and width, slope and length of ramps, including railings, are
16、included in this section.Ancillary components such as floor diffusers and grills, fascias and floor opening trims are also included.Seismic loadings and any other information required to indicate the extent of work must be considered in designing access flooring systems.There are three fundamental c
17、onditions relative to the design of access flooring installations:Condition I Floors are completely surrounded by building walls. These are the most resistant to seismic loadings.Condition II Floors have part of the edge exposed and not restrained by other structural elements. Condition II floors ar
18、e less resistive to seismic loadings along the axis of the unconstrained side. Seismic loadings can be resisted by securing the perimeter panels of all floors to the supporting structural framing and fitting the panels tightly together, or by cross bracing the structural frame to resist overturning.
19、 The designer must select fascia type and finish for exposed edges.Condition III Floors are free standing without lateral contact with other structural elements. Type III floors are primarily strengthened with cross bracing to resist lateral loads.Buildings not excluded by UFC 3-310-02A or TI 800-01

33、er or stringerless system. Refer to Section 09 69 19 STRINGERLESS ACCESS FLOORING for stringerless applications.A stringer is a horizontal framing member that connects the pedestal head, supports the panel edges and adds lateral stability to the floor system. Stringers should be used on all systems
34、with a height that exceeds 300 mm (12 inches).For Army facilities, specify the stringer system when the total area is over 371 square meters (4000 square feet) unless the system provides bolted connection between the panel and pedestal.For Army facilities requiring stringer type systems, aluminum, h
35、older formed steel, metal-clad cementitious fill, metal-clad wood core and concrete panels may be used.For Air Force facilities, use stringer Type floor systems for data processing facilities.For Air Force facilities requiring stringer type floor systems, aluminum, hollow formed steel and metal-clad
36、 wood core are permitted options.Consideration should be given to loads which will be imposed during operation. Some equipment, such as high speed printers require large quantities of paper to be delivered by carts. When in motion, SECTION 09 69 13 Page 7Provided by IHSNot for ResaleNo reproduction

Check with user activity and floor system manufacturer when heavy rolling loads are expected.Zinc whiskers can occur on the underside of raised floor systems which are treated with a zinc elec

The result is possible electrical shorts and damage to circuitry and equipment.*Install access flooring at the
