How to cut a brick wall opening And install sliding door

Sliding Door Installation into an existing wall.

Below is the installing of an Windows Instock 2.4Hx 3.6W sliding door to an existing brick wall.

Preparation:

Refer to approved Engineering plan, requires 200 PFC steel lintel inside room and 200x100x10 steel angle for outside brick wall lintel.

Protection work: 3 length of 1.8meter 100PFC steel, 8 acrowprops.

Lifting: 1 hand manual forklift.

Other tools: framing gun, drill, screws, bugle screws,  angle grinder, hammer

We supervised a job for client to install a 2.4Hx 3.6W sliding door on a flush brick wall. Following are the procedures how we did it from scratch.

Step 1: Disable electrical and air conditioning service. Setout of the opening from inside. This can be done 2 ways. One is to centre the sliding door, or match the brick course . In this situation home owner chose to centre the sliding door to the room.

 

after electrical and airconditioning services removed, we setout the opening from inside room. There actually was 2 options to set out, one is to centralise the sliding door, or match the brick course you don’t have 2 sides bricks cut. In this case our client chose to center the sliding door and cut both side bricks, make us harder to work.

Step 2: Install of temporary protection and supporting measures

4 acrowprops supporting the upper floor joist. In this case the floor truss runs parallel to the wall.

 

Step 3, Steel PFC installed and supported as per engineer plan.

             Temporary Protection can now be removed.

 

Step 3, have the steel PFC installed and supported and connected as per engineer plan.
protection work can be removed

Step 4, For brick wall cut outs. Firstly we need to have the upper bricks supported by 100 steel PFCs, 900mm at 500mm spacing.

to cut open the brick wall. We need to follow engineer procedures to avoid disaster result. Firstly we need to have the upper bricks supported by 100 steel PFCs, 900mm spacing and 500mm away from ends.

Step 5, For the supporting structures, 3 courses of bricks is needed to accommodate the 200x100x10 brick lintel.

now its safe to knock out 3 courses of bricks to accommodate the 200x100x10 brick lintel

Step 6 Re-brick to the top of lintel, use solid packers to avoid sunken mortar, a week is required for mortar cure loadbearing.

Safely start knock out the bricks below the lintel.

 

brick back the bricks on top of lintel, use solid packers to avoid mortar sunken, and leave the protection work for a week to dry out to be loadbearing.

Step 7 Installation of sliding door, trimming of the bricks.

In a weeks time to we will go back to remove protection props, patch plaster.

install the sliding door, trim the bricks, clean the site, job done! And subcontract will come back in 1 week time to remove protection props, patch the plaster.
