FIXING OF FRAMES

 

Preliminary works on site

 

1.Verify the opening sizes on site in tandem with concrete masonry walls and / or Brick walls as per the approved shop drawings.

2.Request to the main contractor in writing for repair or modification to the opening, if the walls are not as per the approved drawings. Refer to TASK Site Inspection Report.

3.Verify access to the desired location for material, equipments and personnel, site conditions, clear the area to avoid conflict with other subcontractors activity.

4.Clean the area and walls prior to installation, if necessary.

 

Fixing of frames: Block wall

 

A]        PREFIXING INSTALLATION PROCEDURE FOR BLOCKWORK WALL

 

1. Position the frame in the opening location.
2. Support the frame with wood bracers so that the frame is in upright position, in plumb and in correct alignment.
3. Set brace and plumb frame.
4. Remove the temporary bracers fixed on the bottom part of the frame in the factory. Fix the Floor anchors in the floor.
5. Start erecting the block wall around the frame.
6. Place the wire anchors on the blocks between the frames and the block wall at the predefined levels.
7. Use spreaders to maintain square ness and alignment of frame, and to maintain door opening. A second spreader is recommended at the mid point of the door opening to maintain the door opening dimensions.
8. Grouting of the frame can be done after enough time is given for setting of the blocks and the lintel. Care has to be taken to avoid excessive load from coming on to the frame while casting the lintel (lintel in others’ scope).
9. Plywood shuttering is done to cover the area between the frame and the wall. Backer rod or plugging material should be used where gaps occur between frame and wall.
10. Pour grout from top of the frame where the hole in the wall is provided by the main contractor. The hole should be about 20mm in diameter in the lintels.
11. Continuously check plumb and square ness as the grouting progresses.
12. Upon the drying up and solidifying of the grout, remove the ply and check plumb and level of the frame once again.
    

NOTE:

1. To improve bonding of grout to the wall, gaps will be left on the edge face of the blocks at anchor locations.

 

2. Refer to the project specific Inspection Test Plan describing the sequence of inspections and coordination with other trades in case of electric hardware or security hardware. Refer to the standard Inspection Test Plan attached.

 

 B]   POSTFIXING INSTALLATION PROCEDURE FOR EXISTING BLOCKWORK WALL

 

1. Position the frame in the block wall opening.
2. Remove the temporary bracers fixed on the bottom part of the frame in the factory.
3. Place the starter bar in the bottom of the frame(to be used instead of the floor anchors)
4. Slide the wire anchors between the frames and the block work wall in the slots provided by the main contractor.
5. Support the frame with wood bracers so that the frame is in upright position and in correct alignment and plumb.
6. Use spreaders to maintain square ness and alignment of frame and to maintain door opening. A second spreader is recommended at the mid point of the door opening to maintain the door opening dimensions.
7. Plywood shuttering is done to cover the area between the frame and the wall. Backer rod or plugging material should be used where gaps occur between frame and wall.
8. Pour grout from top of the frame where the hole in the wall is provided by the main contractor. The hole should be about 20mm in diameter.
9. Continuously check plumb and square ness as the grouting progresses.
10. Upon the drying up and solidifying of the grout, remove the ply and check plumb and level of the frame once again.

 

NOTE:

1. To improve bonding of grout to the wall, gaps will be left on the edge face of the blocks at anchor locations.

 

2. Refer to the project specific Inspection Test Plan describing the sequence of inspections and coordination with other trades in case of electric hardware or security hardware.

INSTALLATION PROCEDURE FOR FRAME ON CONCRETE WALL

 

1. Position the frame near the opening.
2. Slide frame into the wall opening.
3. Mark the position of the anchors on the concrete wall and remove the frame.
4. Drill holes to receive the anchors. Fix the frame with the help of E/ON anchor bolts in the wall and the floor anchor(Starter Bar)
5. Set brace and plumb frame.
6. Use spreaders to maintain square ness and alignment of frame, and to maintain door opening. A second spreader is recommended at the mid point of the door opening to maintain the door opening dimensions.
7. Plywood shuttering is done to cover the area between the frame and the wall. Backer rod or plugging material should be used where gaps occur between frame and wall.
8. Pour grout from top of the frame where the hole in the wall is provided by the main contractor. A gap of 25mm provided as per the design in between wall & frame is sufficient for the pouring of the grout.
9. Continually check plumb and square ness as the grouting progresses.
10. Upon the drying up and solidifying of the grout, remove the ply and check plumb and level of the frame once again.
11. The holes kept open for the anchor bolts are covered with welding small round steel pieces, finished and painted to match the frame color.

 

NOTE: Refer to the project specific Inspection Test Plan describing the sequence of inspections and coordination with other trades in case of electric hardware or security hardware.

 

INSTALLATION PROCEDURE FOR FRAME ON DRY WALL

 

1. The correct position of the frame is marked on the floor with grid reference line.

 

2. Position the frame in the desired location and fix the frame with the help of floor anchors. Wooden supports will be given to the frame to keep it upright position.

 

3. Drywall fixing team will fix the bottom runner on the floor & the vertical “C” stud

 

4. Fix the frame to the vertical “C” stud with the help of metal stud “Z” anchors.

 

5. Use spreaders to maintain square ness and alignment of frame, and to maintain door opening.

 

6. Drywall gypsum board fixing and the grouting will be done by the drywall sub-contractor.

 

NOTE: Refer to the project specific Inspection Test Plan describing the sequence of inspections and coordination with other trades in case of electric hardware or security hardware.

FIXING OF DOORS

 

1. Installation of the doors only to be carried out after all the work on the wall is done and the wall is ready to take the load of the door.(Eg: in open condition)
2. Installation of doors to be carried out strictly adhering to manufacturer’s recommendations & SDI standard.
3. Hang the leaves with screws on the hinges.
4. Once the weight of the door is on hinges tighten the hinges in the order of top and bottom together and then the centre one. Apply all screws and tighten them until flush with the hinge. Adopt same procedure for the continuous hinges
5. The door leaves to hang on the respective frames with proposed kind of hinges.  
6. Ensure SDI and industry tolerances between the frame and the door are maintained.
7. Install other hardware e.g. locks, closers, etc., as per their respective manufacturers instructions and SDI standards
8. Employ skilled technicians for installation and TASK to provide qualified engineers for supervision.

 

Inspection and handover of frames and doors

 

Refer to the Work Inspection Request (WIR report) for the inspection by the consultant for the handover of the assembly.

 

 

PRODUCT PROTECTION

 

Recommend: Protection after installations will be as follows,

Frames by corrugated cardboard sheets wrapped around and held in place with masking tape.

Doors by corrugated sheets wrapped around and held in place with masking tape.  The doors will be kept in non operative state, either closed or wide open.

Door hardware, once installed, to be protected either by masking tape or polythene sheets.

RECTIFICATION  (IF REQUIRED).

 

–        Recommend:
