General Information

General information, overview and instructions needed before performing work.
Read this manual carefully. This manual will provide instructions on building the sidewall and stiffeners. You will also need to consult other instructions in building the tank.
These include, but may not be limited to:
• A stiffener and sidewall gauge layout chart. If such a chart is not included with this manual, contact GSI.
• Roof instructions must be followed. Roof instructions are included in this manual.
• Ladders, roof stairs, roof handrails and other products are covered by separate instruction manuals. Consult the appropriate accessory manual. Inside ladder instructions are included in this manual.
• Aeration systems and transitions are to be installed according to the instructions provided with the system or transition.
• It is critical that the anchor bolts are installed and spaced correctly.

Anchor Bolt Charts

Prior to setting any anchor bolts, you must be sure to have the correct anchor bolt placement. This is very critical for stiffener alignment during bin erection.
NOTE: Refer to the proper chart to find the anchor chord dimensions that correspond to the bin that is
being built.
Start with one anchor bolt and work from it to the left to locate one quarter of the anchor bolts then to the right to locate another quarter of the bolts. Working off of the last anchor bolts in each quarter, locate the remaining anchor bolts in the last two quarters.

• Step ladders
• Large C-clamp or welding V-grip for clamping
NOTE: Quantities required will depend on the number of workers and size of the bin.

Guidelines for Proper Storage of Grain Bin Materials Prior to Construction

Storage of the build materials prior to construction is important. Do not to allow moisture to remain between sheets or panels.
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If moisture is present, it must not be allowed to remain between the sheets. Separate the sheets or panels immediately and wipe them down. Spray with a light oil or diesel fuel
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so that they are raised above the ground and vegetation. Any stacking and spacing materials should not be corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the bun­dles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of mois­ture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they do not fall over and cause injury.
If “white rust” or “wet storage stain” occurs, contact the manufacturer immediately about ways to minimize the adverse effect upon the galvanized coating.

Chapter 2: General Overview

Overview for a Typical Bin Installation

These are the typical steps one would perform when constructing a grain bin. Procedures may vary depending different site requirements.
Pre-Assembly Activities
• Sorting and grouping parts
• Assemble A-frames
• Assemble center collar
• Assemble cap plate
Assembly
• Build two rings of sidewall sheets for even ringed bins or one ring or three rings for odd ringed bins, making sure to caulk all seams.
• Add top outside stiffeners and inside stiffeners at the same time to the two rings of sidewall sheets (Note: These top stiffeners are the lightest gage stiffeners and will get heavier as the bin is raised. Therefore, the heaviest stiffeners are located at the bottom of the bin and are installed last.
• Install wind ring to help support the rings
• Install the center collar tower support in the center of the bin
• Install the eave brackets to the inside stiffeners
• Install eave angles to the sidewall sheets (Note how these are aligned.)
• Install the tension member to the eave brackets
• Lift pre-assembled A-frames, installing them in “opposite pairs” (across from one another) to balance out the load as you install
• Install lower roof panels
• Install upper roof panels
• Cut roof exhauster holes evenly spaced in upper panels
• Install upper flashing
• Install roof exhauster
• Install flat top

Chapter 2: General Overview

Guidelines for Construction Procedures and Lifting Jack Usage

The following procedure is a guideline when using the required lifting jack. Follow this general guideline when lifting the bin as sidewalls are being installed.
NOTE: The roof and the top ring for odd ringed bins or the roof and two rings for even ringed bins, will be
installed prior to the beginning of bin lifting procedures. Refer to all other procedures on sidewall and stiffener installation prior to the start of construction.
IMPORTANT: Begin building with the bin oriented for doors and material handling equipment to be in the
correct position when bin construction is complete.
1. Consider the starting location of the bin, relative to the location of doors and other accessories. Proper placement of lifting jacks in relationship to anchor bolts could make a difference in final loca­tions. Note that the sidewall sheets will be staggered.
2. The bin is lifted by the use of lifting jacks. Lifting jacks are used to slowly and evenly lift the bin during construction. Lifting jacks must be properly sized and designed to carry all loads and job site condi­tions associated with the construction of the bin..
The number of lifting jacks required is best determined by personal experience and expertise. Factors such as bin size, jack design, construction conditions, support surface, etc., are all to be considered when deciding how many to use. If in doubt, use one jack on every sheet. The lifting jack must be adequate to carry all loads. Heavy duty jacks, generally hydraulic or electric powered in the case of large bins, should be used for commercial installation. All jacks should be secured with braces or oth­erwise maintained in a stable condition..
Lifting of the bins should not be done under windy conditions
Follow the jack manufacturers recommendations on capacity and operations.
3. Lifting brackets should be attached through the stiffener bolt holes. Normally you will need to attach to at least four (4) bolts per stiffener.
4. Raise the bin just high enough to assemble the next ring. When lifting the bin, all jacks must lift at an equal rate. Monitor the lift to ensure even lifting is occurring.
5. To the inside of the first ring, bolt the next ring. Be sure to stagger the sheets and select the proper gauge material.
6. Lower the bin onto the foundation after assembling and tightening bolts on the new ring or rings.
7. Attach stiffeners to the body sheets every two (2) tiers (on the external surface of the bin). You may want to leave sheets loose to make the attachment of the stiffeners easier.
8. Now re-bolt the lifting brackets to the lowest ring in place thus far. Continue ring additions by repeat­ing Step 5 and Step 6.
9. Add inside and outside ladders as you continue to raise the bin. (Refer to the manual supplied with the ladder.)
10.Lower the tank and secure to the foundation before leaving the job site.
11.At the completion of the tank, set stiffeners over the anchor bolts and measure the tank to ensure it is in a round condition. Consult with GSI for questions on tolerances.
NOTE: For 2 ring doors or vehicle traffic doors, special placement issues may apply. Consult the special
instructions provided with two ring doors or vehicle traffic doors for these options.

Chapter 2: General Overview

Guidelines for Placement of the Decal Sidewall Sheet

Use the following as a general guideline the proper decal sheet placement.
NOTE: Refer to the stiffener to sidewall attachment detail and specific gauge sheet for the bin. The decal
sheets are located in the third ring from the top. They are to be spaced evenly around the diameter of the bin.
Figure 2-2 3 Post Bin with three rows of stiffeners used on each sidewall sheet
NOTE: Dashed lines represent stiffener locations.

Sample Gauge Sheet

A gauge sheet should be supplied with every bin and contains important information specific to your bin.
The gauge sheet contains the specific details that are unique to your bin. You must reference this sheet to know the correct order to install the sidewall sheets and stiffeners. The gauge of the sidewall and stiffeners are marked with colors for identification.
It is important to use the correct hardware for each type of connection. The gauge sheet will identify what hardware should be used in a vertical seam, horizontal seam, and an overlapping seam for each gauge.
The gauge sheet will also identify the sidewall ring where the wind ring must be installed. This is indicated by the word ”Standard” under the wind ring column and in the row of the ring it must be installed. If a side­draw system is used, the word ”Additional” will be located in the row of the ring it must be installed.
Doors are to be installed in the ring or rings denoted with (D).

Identifying Bolt Grades

Bolts are identified by grade (or hardness), the grade can be identified by the markings on the head of the bolt. These markings will be in the form of slash marks and patterns. Use the following as a guide to deter­mine the correct bolt grade.
Under no condition shall any other bolts be substituted for those supplied by GSI.
CAUTION
Grade 2 Bolts
Grade 2 bolts are designated with a plain head and are not used in GSI grain bins.
Grade 5 Bolts
Grade 5 bolts are designated by three slash marks on the head. All 5/16 inch diameter bolts are to be grade 5 or higher.
Grade 8 Bolts
Grade 8 bolts are designated by six slash marks evenly spaced out around the head of the bolt. All 3/8, 7/16, and 1/2 inch diameter bolts are to be grade 8 or grade 8.2.
Grade 8.2 Bolts
Grade 8.2 bolts are designated by six slash marks on the head in a sunrise pattern. All 3/8, 7/16, and 1/2 inch diameter bolts are to be grade 8 or grade 8.2.
NOTE: Refer to 2.66" commercial tank bolting requirements for complete bolt usage.

Topics Covered in this Chapter
Installing the Base Angle ▪ Anchor Bolt Detail ▪ Installing the Base Angle Shims ▪ Anchor Bolt Washer Installation

Installing the Base Angle

Installing the base angle ring will help reinforce and seal the final ring.
What You Should Know
The base angle overlap should be offset two holes from the stiffener. Do not place overlap in line with the stiffener.
1. Place a section of the base angle (B) to the bottom portion of the final ring (A).
NOTE: The sidewall sheet will sit on top of the base angle with the vertical portion of the base angle
on the inside of the bin. and each end of the base angle will connect to the next base angle section.
2. Install bolts (C) and nuts (D) as shown, but leaving the end holes of each section unfilled until the next section is to be installed.
3. Attach the next base angle section overlapping the end holes (F) and install bolts (C) and nuts (D).
4. Repeat this procedure for the remaining base angle sections (B) over lapping the previously installed base angle section.
5. Before the bolts (C) are tightened, push the base angle tight against the bottom edge of each sheet.
6. Tighten the hardware to the recommended torque specifications, see Bolt Torque Specifications,
page 24.
7. Before lowering the bin, apply the optional mastic sealer strip (G) to the entire underneath side of the base angle.
NOTE: If optional mastic sealer strip is not used, it is recommended that some other method should
be utilized to seal the base ring to the concrete.
8. Lower the bin onto the foundation and check for an adequate seal.

Chapter 5: Base Angle Installation

Installing the Base Angle Shims

A section of the base boot plate will rest on top of the base angle, therefore causing the base boot to rest unevenly on the foundation. To offset this, base angle shims are required to ensure the base boot sets evenly on the foundation.
What You Should Know
1. Place the required base angle shim around the anchor bolt next to the base angle.
2. Place the base stiffener over the anchor bolt onto the required shim.
3. If needed, add standard shims under the required base angle shim.
NOTE: If more than one additional shim is required, then the shims must be welded together to the
base plate or the base plate must be grouted to provide the proper elevation.

Stiffener Part Number Description

Part numbers are printed on the end of each stiffener with the last two numbers designating the gauge of the material.
Example: CTS-206314 will be printed on a 14 gauge, standard two-ring stiffener. If the stiffener was 8 gauge, it would change the part number to CTS-206308.
The part numbers in the following tables use an “XX” at the end of the number to represent the gauge of the material.

About Temperature Cable Brackets and A-Frame Assemblies

Temperature cable bracket installation locations must be considered prior to assembling the A-frames.
Installation Locations for Temperature Cable Brackets
Before assembling the A-frames, you must know the installation locations of the temperature cable brack­ets within the A-frame assemblies. Temperature cable brackets are installed at the same time as the pur­lins are installed.
This information is provided solely for the purpose of facilitating proper support bracket placement. It is fully the responsibility of the dealer, customer, contractor, or said agent of such parties to confirm the details of the system to be used. GSI is not responsible for the effectiveness or performance of any tem­perature cable monitoring system or layout.
IMPORTANT: Temperature cable brackets must be installed at the specified locations as shown below.
Any variation from this pattern or cable quantity shown must be reviewed by GSI engineer­ing. This must be reviewed well in advance of the bin order.
Lifting Sequence for the A-Frame Assemblies
The layout of the roof structure consists of standard A-frame assemblies and A-frame assemblies with X­bracing that are installed in a specific sequence to evenly distribute the weight as they are being installed.
The A-frames with X-bracing are strategically spaced around the diameter of the bin and are the first A­frames to be installed. The A-frame assemblies can be installed in the order as shown in the figure below. A-frames are installed across from each other to keep the weight distributed evenly during installation.
Tip
Label each A-frame assembly according to the order it is to be installed as it is assembled.

Assembling the Center Collar

The center collar assembles each A-frame roof rafter section together at the top.
Before You Begin
Determine the correct orientation of the center collar in relation to any stairs or conveyor systems. Each half of the center collar (A) has drilled holes for the installation of the cap plate and side plates that will be installed later. For this procedure, each half of the center collar needs to sit securely on stands or suitable blocks, allowing plenty of room to access the bolts on the bottom side of the assembly.
1. Locate each half of the center collar (A), and install the center collar splice plate (D) to the inside por­tion on the center collar.
2. Install flange bolts (E) and flange nuts (B) to the six center holes located on the center collar splice plate (D).
NOTE: The remaining open holes along the outside edge of the center collar splice plate (D) will be
used when installing the A-frame rafters to the center collar (A).
3. Repeat this process for the other side of the center collar (A).
