PRODUCT DESCRIPTION

Vertigo+ is a one-piece, all-steel, threaded fastening system for suspending threaded rod in pipe hanging, fire protection, electrical conduit and cable-tray applications. Vertigo+ anchors are designed for simple fast installations and for reliable performance to resist static, wind and seismic tension and shear loads in cracked and uncracked concrete.

Vertigo+ rod hanger screw anchors comprised of a nominally 3/8 inch (9.5mm) diameter with a hex coupler head containing internal threads that accepts threaded rods and bolts in ¼ inch, 3/8 inch and ½ inch are issued with an ICC-ES evaluation report ESR-2989. The Powers Vertigo+ rod hanger screw anchors may be used in single anchor applications or in group anchorages if designed according to ACI 318-08 Appendix D and Section 4.1 or 4.2 of ESR-2989 report, as applicable. These anchors may also be used for redundant applications, where multiple anchors support linear elements (e.g. ductwork) if designed according to Section 4.3 of ESR-2989 report.

Vertigo+ anchors are also available with a hex coupler head containing internal threads that accepts metric threaded rods and bolts in M10 and M12 sizes. Vertigo+ anchors with metric internal threads have an identical external profile and are of the same material as imperial sizes.

GENERAL APPLICATIONS AND USES

• Hanging Pipe and Sprinkler Systems • Suspending Conduit and Cable Trays • Lighting Systems and Overhead Utilities • HVAC Ductwork and Strut Channels • Suspended Ceilings

FEATURES AND BENEFITS

+ Simple system for all rod hanging applications in concrete + Internally threaded coupler for easy removability of service items + Ease and speed of installation and attachment + Lower in-place cost, when compared to traditional anchors + Can be installed with an adjustable torque impact driver + Consistent performance in high and low strength concrete

INSTALLATION SPECIFICATIONS

1) Using the proper wedge bit size, drill a hole into the base material to the requirements specified in the installation specifications. The tolerances of the wedge bit must meet the requirements of the published wedge bit range.

2) Remove dust and debris from the hole.

3) Select a powered impactwrench that does not exceed the maximum torque for the selected Vertigo™+ anchor diameter. Attach an appropriate sized impact hex socket to the impact driver. Mount the Vertigo™+ anchor head into the impact socket.

4) Insert the Vertigo™+ anchor into the drilled hole and, while applying initial pressure, slowly engage/drive the anchor into the drilled hole using impact mode until the head of the anchor comes into contact with the base material surface. During installation, debris or dust created by the thread cutting action may cause some resistance to be experienced. This is easily overcome by unscrewing the Vertigo™+ anchor one turn and then continuing to fix the full embedment. The anchor should be snug tight after installation.

5) Insert the threaded rod into the Vertigo™+.

™Vertigo™ +


WARNING:a) Do not initially drive the Vertigo™+ anchor into the drilled hole with the tool at high RPM with no impact mode and no applied pressure on the anchor as this may damage the anchor thread and render it ineffective. If this occurs a new hole should be drilled and a new anchor used.b) Do not spin the hex socket off the anchor to disengage as this may loosen the anchor.

SCOPE OF INFORMATION

The information in this document is for Vertigo+ anchors having internal threads to accept/accommodate metric threaded rods. The information on metric product is derived from the ICC-ES Evaluation Report ESR-2989 on Vertigo+ having threaded coupler with imperial internal threads to accommodate imperial size 1/4”, 3/8” and ½” threaded rods. The Vertigo+ rod hanger are used to resist static, wind and seismic tension and shear loads in cracked and uncracked normal-strength concrete having specified compressive strength of 17.2MPa to 58.6MPa.

An engineering judgment is made to calculate the loads for the Vertigo+ anchor supplied with metric size internal threads to accommodate metric threaded rods. The Vertigo+ anchor with metric internal threads consists of the same outer dimensions (external profile) and is manufactured from the same material as of the Vertigo+ with imperial internal threads. Metric Vertigo+ anchors accept metric threaded rod into internally formed metric threads in the top coupler.

Consulting design engineer responsible for the application shall review, verify and approve the derived version of the information contained inthis document for Vertigo+ anchors to accommodate metric size threaded rods. It is the responsibility of the consulting engineer to ensure all the anchor design requirements for the application at hand/project are met prior to use of Vertigo+ anchor with metric internal threads for theapplication.

(Please see separate section for REDUNDANT FASTENING APPLICATIONS)

1. The data as given below is intended to be used with the design provisions of ACI 318 Appendix D; for anchors resisting seismic load combinations the additional requirements of ACI 318 D.3.3 must apply.

2. Installation must comply with the issued ESR-2989 report and as given in this document.

3. All values of φ were determined from the load combinations of ACI318 Section 9.2 and Condition B of ACI 318 D.4.4. If the load combinations of ACI318 Appendix C are used, the appropriate value of φ must be determined in accordance with ACI 318 D.4.5

4. It is assumed that the threaded rod or bolt used with the Vertigo+ anchors is a steel element with minimum specified properties as listed in the tables. The Vertigo+ anchor is considered a brittle steel element as defined by ACI 318D.1.

5. For all design cases use ψc,N = 1.0. The appropriate effectiveness factor for cracked concrete (kcr) and uncracked concrete (Kuncr) must be used.

6. For all design cases use ψc,p = 1.0 . Section 4.1.5 of ESR-2989 as recommended in the ESR-2989 is used to calculate the values of Npn in

different strengths of concrete for seismic load applications.

7. Pullout strength does not control design of indicated anchors for non-seismic applications.

8. The tabulated values for seismic applications are based on test results in accordance with ACI 355.2, Section 9.5 for equivalent / smaller imperial sizes.

9. Interpolation is not permitted to be used with the tabular values. For immediate base material compressive strength and other design conditions please see ACI 318 Appendix D.

10. The minimum value from the concrete and steel strength shall be used as the strength of anchor.

11. The values are for the anchors installed at minimum critical edge distance Ca1= 70mm, Ca2 ≥ 1.5 Ca1 (see Fig below) and spacing of 3xhef of 108mm in a concrete slab of minimum 105mm thickness.

12. The seismic load values for concrete failure modes where ACI318-08 Clause D.3.3.5 is not satisfied shall be derived as 0.4 times the design strength seismic load values for concrete failure modes where ACI318-08 Clause D.3.3.5 is satisfied.

13. For designs that include combined tension and shear, the interaction of tension and shear loads must be calculated in accordance with ACI318 Appendix D.

14. The steel shear capacities for M10 & M12 sizes in this document are equal to the steel shear capacities for 3/8” size as given in ESR-2989 dated 1-11-2011

REDUNDANT FASTENING APPLICATIONS

For an anchoring system designed with redundancy, the load maintained by an anchor that experiences failure or excessive deflection can be transmitted to neighboring anchors without significant consequences to the fixture or remaining resistance of the anchoring system. In addition to the requirements for anchors, the fixture being attached shall be able to resist the forces acting on it assuming one of the fixing points is not carrying load. It is assumed that by adhering to the limits placed on n1, n2 and n3 below, redundancy will be satisfied.

Anchors qualified for redundant applications may be designed for use in cracked and uncracked concrete. Concrete compressive strength of 17.2MPa shall be used for design. No increase in anchor capacity is permitted for concrete compressive strengths greater than 17.2MPa. The anchor installation is limited to concrete with a compressive strength of 58.6MPa or less.

Redundant applications shall be limited to structures assigned to Seismic Design Categories A or B only.

Redundant applications shall be limited to support of nonstructural elements.

Strength Design (Redundant Fastening):

For strength design, a redundant system is achieved by specifying and limiting the following variables: n1 = the total number of anchorage points supporting the linear elementn2 = number of anchors per anchorage pointn3 = factored load at each anchorage point, kN, using load combinations from IBC Section 1605.2.1 or ACI 318 Section 9.2
