HOUSEKEEPING

LEARNING OBJECTIVE:

Upon completing this section, you should be able to KNOW and APPLY

HOUSEKEEPING at all times.

Formwork construction because of its constantly changing work environment, restricted access through frames and formwork supports and a large volume of material and waste, requires ongoing monitoring of housekeeping practices.

A. Access

Clear access is important for the safe movement of materials, equipment and persons on site. Designated access ways must be provided. Persons must be instructed to use the access ways and keep them clear of any excess wastes, plant or materials. In some situations, it may be necessary to use hazard taping or other visual methods to clearly show where access ways are located. This is particularly important where access is required through formwork frames.

Emergency access and egress must be considered and provided to all parts of the workplace where persons are required to work.

B. Material storage

1. Materials must be stored so as to minimize manual tasks hazards, trip hazards and the potential for falling objects.

2. It is preferable to lay wall forms flat on the ground instead of leaning them against structures or other forms.

3. Timbers, or another effective means, must be provided under the forms where slings are to be placed under the forms for crane lifting.

4. Wall forms must be stacked in such a way that they cannot move away or rotate from the surface they are placed against.

5. Incorrect materials delivery and storage can create significant manual handling tasks. Safe work practices to minimize exposure to these risks include:

• ensuring the formwork materials are delivered as close as possible to the job

(10)

platform to load ply and other components

• ensuring mechanical aids are used to handle loads wherever possible • storing loads on trolleys to minimize double handling or on raised

platforms to minimize manual lifting from ground level

• having adequate storage space or lay down area to safely store materials and equipment and to minimize double handling

C. Storing and Disposing of Waste Materials at the Workplace

Waste material storage and removal for formwork may include the provision of garbage skips and wheel barrows that are moved as work progresses. However, garbage skips should only be positioned where the supporting structure has adequate strength to support the total weight of the bin and likely contents.

SCAFFOLDS SAFETY RULES

Upon completing this section, you should be able to APPLY SAFETY RULES

in ERECTING SCAFFOLDS at all times

These safety rules cover generalized situations only and should not be used to replace any other additional safety and precautionary measures that may be necessary to cover the many usual or unusual conditions encountered during installation or dismantling.

1. Follow safe practice of the safety rules and comply with OH&S laws and other federal, state and local rules, codes and regulations pertaining to

scaffolding during any use of the equipment.

2. The potentially hazardous nature of scaffolding assembly makes it important that all personnel assigned to this work be instructed in theses safety rules, safe practices and procedures and be under the supervision of an experienced person. Ensure that these Safety rules are posted and that all assemblers and users of the scaffold are aware of and follow them.

3. Report any unsafe conditions to supervisors. Do not work or allow persons to work on scaffolds when sick or suffering from dizziness,

unsteadiness or any other physical symptom which could affect their ability to work safe.

4. Inspect all equipment before use. Never use any equipment which is damaged, defective, or deteriorated in any way.

5. Inspect assembled scaffold frequently and be sure that it is maintained in a safe condition, ensure that the scaffold connection have not become loosened and that components have not been improperly released or removed.

6. Maintain all equipment in good repair. Never use corroded or excessively rusted equipment; the strength of such equipment is not known.

7. Consult your scaffolding supplier when in doubt. Never take chances. 8. Always read these safety rules in conjunction with all safety regulations. 9. Always place scaffolds on a sound, stable surface and assure that it is

adequate to support the intended scaffold loads. Never place scaffolds on unstable where loose objects could tip, break or become dislodged.

10.Lift and lower components carefully and safely. Use tag lines where appropriate to the handling method. Never allow excessive quantities of components to be stockpiled on partially complete scaffolds. Stock only sufficient components consistent with the progress of the work. Lower dismantled components as soon as possible. Never drop components deliberately.

(22)

stability and safety of the scaffold. Assure that the structure to which the scaffold is tied or anchored is capable of safely supporting all loads imposed by the scaffold.

12.Free standing scaffolds other than wall scaffolds must be restrained from tipping by guying or other means or otherwise stabilized as appropriate, recognizing that stability is essential to the safety of the scaffold.

13.Install guardrails, midrails, and toeboards at all openings, open sides, and ends of every work platform

14.Never use ladders or makeshift devices on tops of scaffold to increase the height. Never place plank on or stand on guardrails and mid-rails.

15.Power lines near scaffolds are dangerous. Use extreme caution and consult the electrical company to have the lines de-energized, insulated, or otherwise rendered safe. Never allow any installation or use of scaffolds until this is completed.

16.Proper care and precautions must be taken when using cantilevers to prevent tripping of the scaffold

FORMWORK COMPONENTS ASSEMBLY

Upon completing this section, you should be able to APPLY the STEPS IN

ASSEMBLING FORMWORK COMPONENTS

The method and sequence of erecting formwork may vary depending on the availability of lifting equipment and whether reinforcing cages are available. Forms are usually handled manually, by small derrick, or by crane. The erect formwork activity includes the process of lifting, positioning, and aligning the different formwork elements. This activity also includes the process of applying the form release agent or coating that prevents bonding of concrete to forms. The concrete life cycle starts after the erect formwork activity is finished with placing inserts and reinforcement activity.

A. Constructing a Wall/Column Form

Construct column forms from the lowest point to the highest point. Follow these steps when constructing a concrete form:

1. Ensure to get the column form inside dimensions and height. 2. Ensure that the following materials are available:

• Sheathing • Yokes • Battens

• Yoke locks

• No. 4 reinforcing material • Tie wire

3. Build the footing form (refer to Information sheet no. 2.2-1).

4. Build the column-form sides (refer to Information sheet 2.2-1).

4.1 Fasten the column sides. After the four sides of the column form have been constructed, fasten them together and set them in place.

NOTE: The column form should have

a clean-out hole in the bottom to remove construction debris. The

pieces of lumber removed from the clean-out hole should be nailed to the form so they can be replaced right before placing concrete in the column.

4.2 Install the yoke locks.

(31)

4.2.1 Sheathing-type yoke lock. Fasten this type of lock to the yokes with nails or screws.

4.2.2 Bolt-type yoke lock. Drill holes where the yokes intersect and insert bolts, washers, and nuts.

4.2.3 Tighten until they are snug. If available, wing nuts work the best. 4.2.4 Scab-type yoke lock. Cut scabs out of scrap 2- by 4-inch lumber and secure with wood fasteners.

B. Constructing an Overhead Form

1. Construct a concrete-overhead-beam form 1.1 Set the form bottom.

1.1.1 Make the width of the soffit out of 2-inch material, exactly like that of the member being formed, and its length equal to the distance

between the columns or the spans.

1.1.2 Cut the two ends of the form bottom at a 45-degree angle to produce a chamfer at the junction of the beam bottom and column.

1.2 Nail the chamfer strips with beveled ends to the beam-form bottom, flush with the outside edge.

NOTE: Chamfer strips are small pieces of wood (about 1 inch by 1 inch). 1.3 Cut the studs to the length called for in the specifications. 1.4 Cut and fasten the sheathing.

1.4.1 Use either 1-inch tongue and groove lumber or plywood.

1.4.2 Cut the sheathing should be cut to the length called for in the specifications and fasten it to the studs to create both side panels.

1.4.3 Nail sheathing sides so that they overlap the bottom piece of the form.

1.5 Cut and install the temporary spreaders.

1.5.1 Cut the temporary spreaders to the beam as stated in the specifications.

1.5.2 Install the temporary spreaders by using double-headed forming nails.

1.6 Install the shoring.

1.6.1 Use a large quantity of shoring to offset the downward hydrostatic pressure placed on the form bottom. Commercial adjustable-metal forms are available and are probably the best and easiest type of shoring to use on beam and girder forms (Figure 052-236-1165-2). Heavy timber such as 4- by 4-inch lumber is normally available and works fine. 1.6.2 Install shoring so that the beam form remains level.

(32)

Beam and Girder Form

C. Constructing a Concrete-Slab Form

1. Construct a wooden-form slab

1.1 Construct the formwork. Measure and mark the side-form material to the required lengths.

1.1.1 Make two pieces the actual length of the slab and two pieces length of the slab plus two times the thickness of the material. 1.1.2 Nail the form sides together at the corners.

1.2 Place and secure the formwork.

1.2.1 Place the formwork at the specified location. 1.2.2 Square the forms

by using the diagonal method.

1.2.3 Drive the stakes at all the corners and

approximately 3 feet along the entire perimeter of the form. 1.2.4 Level the

formwork, then nail the forms to the stakes. 1.3 Cut and place

polyethylene plastic in the bottom of the form as a vapor barrier. JZGMSAT QA SYSTEM Carpentry NC II INSTALLING FORMWORK COMPONENTS Date Developed: Aug. 1, 2011 Document No. Issued by: Page 32 of 38 Developed by: Glenn F. Salandanan Revision # ____
