1、Designation: C 1354/C 1354M 09Standard Test Method forStrength of Individual Stone Anchorages in DimensionStone1This standard is issued under the fixed designation C 1354/C 1354M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the

2、 year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method provides procedures for determiningthe ultimate strength of an assembly consisting of stone

3、withmechanical anchor (anchorage). Load is applied, separately,perpendicular to the surface of the panel and parallel to thesurface of the panel. This test is intended to represent theinteraction of the anchor with the stone panel. However,influence of the backup structure on the strength of theasse

4、mblies is not included.1.2 This test method is applicable to stone panels supportedby mechanical anchors.1.3 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. Thevalues stated in each system may not be exact equivalents;therefore, each system sh

5、all be used independently of the other.Combining values from the two systems may result in non-conformance with the standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish app

Terminology3.1 Definitions:3.1.1 anchor, nin general, a metal shape inserted into aslot or hole in the stone panel that provides for the transfer ofloads from the stone to the build

8、ing structure, either directly orthrough an intermediate structure.3.1.2 anchorage, nassembly consisting of a stone panelwith a mechanical anchor.3.1.3 panel, ncut stone with large face dimensions inrelation to its thickness, for placement in a building structure orframe assembly.4. Summary of Test

9、Method4.1 Test specimens consisting of a stone panel sample and amechanical anchor are fabricated in the same manner and ofthe same materials as their intended construction uses. Themechanical anchor is connected to a test support. A test load isapplied perpendicular or parallel to the face of the s

10、tone panel.The test load is applied gradually using a calibrated testmachine; load is increased until the stone or the mechanicalanchor fails.4.2 The load at failure and mode of failure of each testspecimen is observed and recorded. The test as described aboveis repeated five times for each combinat

11、ion of stone and anchorto be tested and for each direction of load to be tested.5. Significance and Use5.1 This test method is intended to provide informationfrom which applicable design data can be determined for agiven anchor used to support a dimension stone panel. Thestrength of a limited length

12、 of anchor may be related to a longerlength of support when the flexibility of the support is properlyconsidered by the designer. Refer to Guide C 1242.1This test method is under the jurisdiction of ASTM Committee C18 onDimension Stone and is the direct responsibility of Subcommittee C18.01 on TestM

Testing Machine6.1 The testing machine shall conform to the requirementsof Practices E4.6.

15、2 The load from the testing machine shall be appliedthrough appropriate devices (a lubricated ball-and-socket or alubricated universal joint) to apply direct tension to the testspecimen without bending.7. Support Frame and Loading Device7.1 The support frame (excluding the anchor to be tested)shall

16、have sufficient strength to not yield while supportingmaximum applied load. In addition, the support frame shall besufficiently stiff to limit deflection to less than 0.04 in. 1 mmat maximum test load and to limit rotation to less than 2.7.2 For load perpendicular to the surface of the stone panel:7

17、.2.1 A rubber pad or a setting gypsum bed shall be usedbetween the stone and the loading or restraint surface to avoidconcentration of stress in the surface of the stone sample.7.2.2 A frame to support a stone sample with anchor in theside edge of the stone is shown in Fig. 1. Fig. 1 representsoutwa

18、rd loading on a single stone panel. At the designersoption, two stone panels can be tested on a single split anchor.7.2.2.1 The test specimen is supported at one end by theanchor. The anchor shall be attached to the support frame in thesame way it will be attached to the backup structure inconstruct

19、ion. The sample of stone is supported at the oppositeend by a 1 in. 25 mm diameter rod.7.2.2.2 The load from the testing machine is applied to thestone sample through a 1 in. 25 mm diameter rod, located asclose as possible to the anchor that supports the stone but at adistance not less than the thic

20、kness of the panel.7.2.3 A frame to test a stone sample with anchor in back ofthe stone and the load applied in a direction perpendicular tothe panel are shown in Figs. 2 and 3. The sample of stone panelis held down while the upward load is applied through a singlesample of anchor. The stone sample

21、may be held down byindependent anchors as shown in Fig. 2 or by the device usedto apply load as shown in Fig. 3.7.3 For load parallel to the surface of the stone panel:7.3.1 The stone panel sample is restrained in the plane of thepanel while a test load is applied parallel to the plane of thepanel a

22、s shown in Fig. 4. The area beneath the anchor shall bekept unsupported to prevent restraint of spalls that mayFIG. 1A Edge of Panel Supported by Tab Inserted into Kerf in Edge of PanelFIG. 1B Edge of Panel Supported by Pin Installed into Hole Drilled into Edge of PanelFIG. 1 Setup for Testing Conne

If sealant,epoxy, or other form of kerf filler is specified to be used in fieldconstruction, the bond between the sealant, epoxy, or otherform of kerf filler shall be intentio

At the designers option, the sealant or epoxy may beallowed to bond.8.2 Anchor InstallationInstall the anchor and accessoriesin accordance with t

26、he specified design.8.3 Number of SpecimensFor each combination of stoneand anchor to be tested, test at least five specimens. Whereedge connections are used, a set of five specimens shall betested with connection made in each of the two perpendicularedges.NOTE 1More specimens may be needed dependin

27、g on the variabilityof the test results. If necessary, determine suitable statistical parameters toevaluate the composite variability and to select the number of specimensneeded for obtaining a given minimum precision in determining thecapacity of the anchorage system.8.4 Stone Panel SamplesSelect r
