9、UIDE SPECIFICATIONSReferences are in agreement with UMRL dated July 2010*SECTION 09 69 19STRINGERLESS ACCESS FLOORING08/10*NOTE: This Guide Specification covers the requirements for stringerless access flooring.Edit this guide specification for each project specific requirements by adding, deleting,
10、 or revising text. 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 welcome and should be directed to the t
11、echnical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the Internet.Recommended changes to a UFGS should be submitted as a Criteria Change Request (CCR)Brackets are used in the text to indicate designer choices
12、 or locations where text must be supplied by the designer.*PART 1 GENERAL*NOTE: 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 i
13、tems such as steps, ramps, closures and trim. Access flooring systems must be designed to accommodate static, rolling and impact loading.None of the mechanical and electrical services SECTION 09 69 19 Page 3Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS
14、-,-,-essential to the operation of equipment are included. Coordinate with mechanical and electrical to provide ventilation and cable openings which will be required.The designer is responsible for identifying and defining requirements for the floors. Drawings must indicate location and limits of th
15、e flooring systems, finish floor elevation, panel size, type, finish and anti-static provisions, colors, pedestal mounting and subfloor connection system details.RIGID GRID ACCESS FLOORING is covered in SECTION 09 69 13.Stair and/or ramp information, such as tread width and riser height for stairs a
16、nd width, slope and length of ramps, including railings, are 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 de
17、signing access flooring systems.There are three fundamental conditions 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 re
18、strained by other structural elements. Condition II floors are 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
19、 by cross bracing the structural frame to resist overturning. 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 later
20、al loads.Buildings not excluded by UFC 3-310-02A or TI 800-01 Design Criteria will be accessible in accordance with 36 CFR, Part 1191, Americans with Disabilities Act (ADA) Accessibility Guidelines for Buildings and Facilities.On the drawings, show:SECTION 09 69 19 Page 4Provided by IHSNot for Resal

33、ess flooring support systems are available as either a stringer or stringerless system. Refer to Section 09 69 13 RIGID GRID ACCESS FLOORING for applications using stringers.Consideration should be given to loads which will be imposed during operation. Some equipment, such as high speed printers req
34、uire large quantities of paper to be delivered by carts. When in motion, these heavy loads may exceed capacity of floor system. 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 trea
35、ted with a zinc electroplated anti-corrosion coating. Zinc whiskers are small enough (2 microns in diameter up to several millimeters in length) to render normal dust filters on computer equipment ineffective. The result is possible electrical shorts and damage to circuitry and equipment.*Install ac
