E Angle Bracket for Cross-Laminated Timber

Heavy Angles

This product's information may differ depending on the category of use. You are currently viewing details related to Heavy Angles. You can also view product information related to the category: Misc. Connectors for Engineered Wood

E angle brackets are used to connect cross-laminated timber (CLT) wall panels to concrete slabs. A wide variety of fastener and anchor options are available depending on the required loads and application.

The E20/3 angle bracket has been load-rated with up to a 2-inch gap between the bottom of the CLT wall and the top of concrete slab. This gap allows the wall to be separated with a pressure-treated sill plate, concrete curb, grout pad, or other specified material.

  • Loads provided for screws or nails
  • All load directions addressed
  • Heavy gauge provides high load capacity
  • Anchorage to concrete
  • Load-rated with up to a 2-inch base-of-wall gap

Material

  • 11 gauge

Finish

  • Galvanized

Installation

  • Use all specified fasteners and anchors
  • Follow installation images

  1. The allowable loads are based on the use of SPF Grade 2 cross-laminated timber (CLT) material conforming to APA PRG-320.
  2. Installation and fastener schedule in "CLT Panel to Panel Connection" table assumes platform framing, i.e., install vertical leg at bottom edge of CLT wall panel, and horizontal leg on CLT floor panel with 3 7/8 in. min. edge distance.
  3. Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce for other load durations as required by code.
  4. The designer must specify the anchor bolt type, length, and embedment. Allowable load shall be taken as lower of anchorage capacity per designer and table load.
  5. See Engineering Letter L-C-CLTABSDPWS for F1 loads calculated in accordance with Special Design Provisions for Wind and Seismic 2021 (SDPWS2021).
  6. Nails: 0.162" x 2 1/2" = 0.162 in. diameter x 2.5 in. long.
  7. Screws: SD10 x 1 1/2" and SD#10 x 2 1/2" = 0.162 in. shank diameter x 1.5 in. long and 2.5 in. long Simpson Strong-Drive® SD Connector screw respectively. SDHR27400 = 0.275 in. shank diameter x 4 in. long Simpson Strong-Drive® SDHR Combo-Head screw.

  1. Allowable anchor capacities have been determined using ACI318–14 Chapter 17 calculations with a minimum concrete compressive strength (f'c) of 4,000 psi in normal–weight concrete.
  2. Load values are for group anchors based on ACI318, Condition B, no supplemental edge reinforcement, Ψc,V = 1.0 for cracked concrete and periodic inspection.
  3. Allowable Stress Design (ASD) values were determined by multiplying the LRFD capacities by a conversion factor, Alpha (a), of 0.7 for seismic and 0.6 of wind loads.
  4. Tabulated allowable ASD loads for Wind and Seismic in SDC A&B are based on a wind conversion factor and may be increased by 1.17 for SDC A&B only.
  5. Design loads shall include seismic overstrength factor per ASCE7 Section 12.4.3, as required.
  6. Allowable load shall be taken as lower of anchorage capacity or the connector capacity. Anchors subjected to both tension and shear loads shall be evaluated per ACI318 Section 17.6.
  7. Anchors: THD37300 and THD37400 = 3/8" diameter x 3" long and 4" long, respectively, Titen HD Heavy-Duty Screw Anchor.
