In this article, you will learn the method of fixing door frames step by step with a detailed guide so read the full article to avoid any problem and achieve high-quality work
Fixing of door and window frames in existing openings should be done properly, including the initial operation, drilling holes, fixing frames and necessary preparations for the final works.
Proper fixing of frames prevents defects and subsequent wall failure or obstruction of windows.
Guide to Fix Door and Window Frames in Openings Step by Step
This article discusses how to fix door and window frames in the existing openings.
#1 Cleaning and Preparation of Existing Openings
- Remove all attached part such as window frame or existing door with the opening.
- Remove bolts, lugs and screws and make it clean.
- Fix existing opening by filling concrete or grout in cavities or holes.
- Also clean opening from dust or debris.
- In case of a damaged opening, the size and the corner shall be repaired.
#2 Drilling of Holes for Fix Fram
- If you want to fix door frames without sills then create at least a 40 mm deep hole in the floor for fixing the lower part of door frames.
- For doors with sills, the sill plates shall be partly fixed on the floor to project above the floor to a height as directed by the engineer.
- The required number of holes in the appropriate areas will be cut in the installation structures for door handles, windows, or removal windows.
- The size of the holes shall be such that the frames with the holdfasts can be conveniently erected in position.
- Where necessary, stone construction will be uniformly designed to facilitate the installation of the frame opening.
- Special care will be taken when drilling holes in the load-bearing pillars or on sections of the wall separated by openings to ensure that the supporting beams are properly supported.
- In such parts, holes will be cut on one side at a time.
- The sides of the holes shall be truly parallel and perpendicular to the plane of the wall.
- Care should be taken not to interfere with the construction of interlocking stone structures and the construction of masonry under arches and arches, etc. The opening opens.
- The holes will be cleaned of all dust, mud, bricks or pieces of stone and completely wet.
#3 Fixing of Door and Window Frames
- The frame's side of the door, window or to be embedded in masonry shall be colour with two-layer coats of coal tar before being placed in position.
- The frames shall then be inserted in position with their holdfasts bolted tight.
- Door frames or windows frames shall then be properly adjusted to the line and plumb also in secured position by temporary bracing which should not be removed or disturbed until hold faces are embedded in the masonry and concrete block has bees fix
- The cement concrete for embedding holdfasts should be M15 grade 1:3:6 where 1 cement:3 coarse sand:6 graded stone aggregate and 20 mm nominal size
- The minimum size of concrete block in which the holdfasts will be embedded shall be 30 x 10 x 15 cm for 35 cm long holdfasts.
- The concrete of the block shall fill the hole made in the masonry for the purpose.
- The chase cut in the floor shall be cut square, and construction joint shall be provided or filled in with cement concrete 1:2:4 (1 cement: 2 coarse sand: 4 graded stone aggregate, 20 mm nominal size) and rendered smooth at the top and finished to match the existing type of floor.
#4 Finishing Work
- After the surface surrounding the holdfasts has sufficiently dried, it shall be cleaned of dust, debris, etc., and wetted.
- It shall then be plastered with cement mortar 1:4 flush and matching with the surrounding plasterwork.
- In case of exposed brickwork, stonework, the finishing shall be done to match the surrounding.
- Any other portion of the wall opening, if damaged, shall be repaired similarly.
- After the cement plaster patches have been thoroughly cured and dried, they shall either be whitewashed or colour-washed as required, unless otherwise specified.
- All waste and debris obtained from cutting etc. shall be disposed of at the nearest dumping ground.
