The layout of a changeroom (mine dry) employing a Moore LOCKERBASKET® System is simplified by using the scaled Dot Matrix Sheet (PDF - 15KB) and following the steps below:

• Locate walls and other physical boundaries affecting the layout.
• Note ceiling beams, joists or other roof support members.
• Locate locking rail-bench units. Where a locking rail-bench unit is desired, ELIMINATE one row of module dots and substitute the locking rail-bench unit, maintaining the 2'-0" module spacing.
• Where an aisle is desired, ELIMINATE one row of module dots, leaving a 4'-0" wide aisle. (Eliminating two rows of module dots will leave a 6'-0" wide aisle).
• Determine average ceiling height in LOCKERBASKET® area (Bottom cord of joist to Floor)
  

Each remaining module dot signifies the center point / location of an individual LOCKERBASKET®.

NOTE: ALUMIBENCH is extruded into 12'-0" sections and designed for maximum spans of 6'-0". For the most economical layout, ALUMIBENCH should be designed using spans in multiples of 6'-0" (3.66M).

Combination Locker / LOCKERBASKET® Installation

LOCKERBASKETS may be used in conjunction with floor lockers when floor storage is desired in combination with overhead storage of clothing. In this configuration, detailers can choose to operate the LOCKERBASKETS using the standard locking rail bench design or from within the floor locker using the MS-80 locker operating equipment package.

The combination of LOCKERBASKETS and wall lockers is an effective way to address the separation of clean and dirty areas of a changeroom (mine dry), whether it be spatially by having two different rooms or by utilizing different clothes storage systems. To assist you in your design of a dual LOCKERBASKET - Locker system, we have made plan and elevation details available for _new.pdf download by clicking on the links below.

When combining the two systems, please first select one of the common locker sizes you wish to use to insure spacing is appropriate for your layout, then lay out a changeroom (mine dry) with the locker/LOCKERBASKET combination so that the layout avoids interference with overhead objects such as structural beams and duct work. It is best to present the structural engineer with the layout out first to insure that the structural engineer designs around the needs of your locker/LOCKERBASKET layout.

Architectural Design Standards for Overhead Clothes Storage Systems

The following design standards for OVERHEAD CLOTHES STORAGE SYSTEMS have been developed with architects and engineers, to provide a spacious, open changeroom/mine dry, while making maximum use of valuable floor space. These design standards are the Manufacturer's acceptable minimum, subject to specification by the Design Engineer.

LOCKERBASKET® Spacing

Recommended spacing of LOCKERBASKETS® is on 24 " (610 mm) centers. This allows generous clearance between LOCKERBASKETS® for free circulation of air through garments. For ease of layout, LOCKERBASKETS®, locking rail bench units and overhead supports are normally spaced on modules of 24" (610 mm).

Aisle Spaces

Aisle spaces are not required with Moore LOCKERBASKETS®, except for the main aisles through the changeroom. Experience has shown that raising and lowering of LOCKERBASKETS® occurs in such ratios that the entire ceiling, except for the main aisles, may be employed for LOCKERBASKET® support.

Locking Rail - Bench Spacing

Generally speaking, the most economical layout will have locking rails spaced either on 14' (4270 mm) centers giving 6 rows of LOCKERBASKETS® between locking rails, or on 10' (3050 mm) centers to give four rows of LOCKERBASKETS® between locking rails.

Ceiling Heights

A. Distance from finished floor to bottom of roof support purlins:

• Recommended: Preferred height is 16'-0" (4876 mm) (Gives a clear height between floor and overhead clothes storage system of 10'-4" (3139 mm).
• Optional: 15'-0" (4572 mm) for smaller changerooms only (Gives normal clear height between floor and overhead clothes storage system of 9'-4" (2835 mm).
• Minimum: 14'-0" (4270 mm) For light industries only.
  

B. In rigid frame structures, the length of the cable is adjusted to allow all LOCKERBASKETS to hang at the same level, giving the effective ceiling heights desired by the architect or engineer. (See detail on following pages.)

Clearance Requirements

2'-0" (610 mm) recommended distance from centerline of LOCKERBASKETS to locking rail and 1'-0" from walls or partitions.

Overhead Supports

MOORFRAME®, the prefabricated overhead framing member, supports the overhead clothes storage system on clear spans up to 8'-0" (2440 mm) without bridging, and to a maximum of 10'-0" (3050 mm) with bridging (see span chart). This member serves as overhead framing equally well in both flat roof and rigid frame structures.

MOORFRAME® also serves as a Locking Rail for the overhead clothes storage system, and is designed for compatibility with Moore Locking Rail Bench Support Units.

Locking Rail Bench Support Units

Moore prefabricated Locking Rail Bench Support Units are designed to serve from one (1) to four (4) rows of LOCKERBASKETS® on each side of the unit. The pedestal support units are protected with a hot dipped galvanized coating to resist rusting in damp environments.

Moore ALUMIBENCH®, used in accordance with these standards, provides comfortable seating for all employees using the changeroom. It is recommended that bench runs be designed in multiples of 6'-0" (1829 mm) for the most economical use of ALUMIBENCH® and Locking Rail Bench Support units.

Roof Load

Roof structure must be designed by a design professional to withstand a 10 PSF (49 kg/ m2 ) uniform load caused by loaded LOCKERBASKETS® in addition to roof loads determined from appropriate building codes and local conditions. The design professional must also separately consider the point loads caused by the reaction of the collector rail. Each LOCKERBASKET® load should be limited to 30 pounds (13 kg).

Floor Area Requirements

For estimating purposes and preliminary layouts, allow 5.5 square feet (0.5 square meters) of floor area per employee using the changeroom (mine dry). This allowance covers area requirements for LOCKERBASKETS®, locking rails, benches and aisles, but does NOT include area requirements for lavatory facilities. On the average, the total requirement including changeroom, toilet, showers and lavatory will average 8 square feet (0.75 square meters) of floor area per employee using the changeroom.

Suggested Layouts For Moore LOCKERBASKETS®

The number of rows of LOCKERBASKETS® between Locking Rail Bench Units may vary from two (2) rows 6'-0" (1830 mm) between locking rails to eight (8) rows 18'-0" (5490 mm) spacing between locking rails. Normally six (6) rows will provide the most efficient design.

Space may be left in the center of some or all bays for an additional row of LOCKERBASKETS® to accommodate planned or unforeseen increases in the number of employees using the changeroom/mine dry. This is an economical way to provide for future growth of the facility.

These basic designs, which employ the best changeroom practices, may be altered to suit the individual room requirements and best utilize the available space.
