C&J Practical - STUD WALL PRACTICE

STUD WALL PRACTICE

INTRODUCTION TO TIMBER STUD WALL CONSTRUCTION

One of the most common methods for partition wall construction is timber framing with plasterboard covering. These walls are known as timber stud walls. Stud walls are most often used for interior work on domestic dwellings and are more commonly non load bearing. However, a stud wall can be load bearing in some cases, so always check before fitting, altering or removing a stud wall

FAST FACTS

WHAT IS CLS?...Canadian Lumber Sizes Timber (CLS Timber) is ideal for internal stud walling and stud partitioning. CLS timber is surfaced on all four sides and has radiused edges. It is produced in a range of sizes and is widely used in the timber frame industry
TYPICAL SIZES:
- The most common size of CLS timber is 38 x 63mm (Sometimes called 3 by 2)
- Sometimes a larger section is needed so 38 x 89mm CLS is also widely available (This is sometimes called 4 by 2)
- The most commonly available stock lengths of CLS timber are 2.4m and 4.8m

TASK INSTRUCTIONS

STUD WALL PRACTICE TASK

TASK STANDARDS

This is a centre-set task, it is designed to build up your skills and prepare you for the site carpentry tasks you will complete during year 2 of your course

To complete this task you must construct the stud wall shown in the drawings provided
All joints are to be fixed using suitable countersunk screws, minimum 2 screws per joint
All screwed joints to be set out at appropriate, even centres
All screwed joints to be pre-drilled and countersunk
You should aim for a neat, professional finish with all joints flush and overall sizes accurate to +/- 5mm, maximum
If you have completed your portable power tool block successfully, you may be allowed to use power tools for this task. ALWAYS ASK YOUR TUTOR BEFORE USING POWER TOOLS

WHAT YOU NEED TO DO NOW

STUDY ALL OF THE RESOURCES PROVIDED FOR THIS TASK, INCLUDING VIDEOS, DRAWINGS, AND WRITTEN INSTRUCTIONS
YOUR TUTOR WILL TELL YOU WHEN YOU ARE READY TO BEGIN
ALWAYS WORK IN A SAFE AND TIDY WAY
MAKE SURE YOUR WORK HAS YOUR NAME ON IT AND IS STORED SAFELY AT THE END OF EACH SESSION

FURTHER RESEARCH

- Why do you think 38 x 63mm CLS is also known as 3 by 2?
- Where would you need larger sections of CLS in a building?
- Why do you think that CLS has rounded corners?
- ASK YOUR TUTOR to tell you about joiner's rods (sometimes called setting out rods)

SIGN OFF

Once you have completed your practical task you need to discuss your results with your tutor and complete some sign off documents, your tutor will show you how to do this.

BUILD SEQUENCE VIDEO

STEP BY STEP GUIDE

STEP 1

Cut a sheet of plywood or MDF 1200mm x 400mm
Mark out as shown in the drawing below (For an expandable view see WORKING DRAWINGS: PLAN VIEW above)
This is the base of your wall and you will use it as a JOINER'S ROD or SETTING OUT ROD to help you mark out your stud walls

STEP 2

Cut a length of 38mm x 63mm CLS 1150mm long, this will be the BASE PLATE timber
Place it on the base exactly as shown and transfer the centre line 'A'

STEP 3

Mark out the stud positions as shown (You can use a short length of CLS to help mark out the 38mm spacings)
Cut another 1150mm length of CLS and carefully transfer the markings from your base plate (use a square for this) This second piece of CLS will be the TOP PLATE

STEP 4

Cut 7 lengths of CLS 790mm long
Assemble the wall as shown using suitable screws, 2 per joint. You will need to mark out for even spacings and pre-drill/countersink as you have learned in previous exercises

STEP 5

Fit 100mm noggings on centre height as shown

STEP 6

The next wall will be constructed using lap joints (This can be useful when a wall needs to be more strong and stable, for example a supporting wall under a stair-case)

Cut 2 lengths of CLS and mark out as shown

STEP 7

Form lap joints as shown using the skills you have gained in previous tasks

STEP 8

Assemble the wall as shown

STEP 9

Fix to the base and adjoining wall using countersunk screws (Remember to pre-drill and check that everything is level, plumb and square)

STEP 10

Cut and fit noggings as shown

STEP 12

Use the outlines on your base to mark out the first section of your angled wall as shown. This is a difficult process, ask your tutor or a more experienced colleague to help you if necessary

(The existing walls have been omitted from these drawings to make them easier to follow)

STEP 14

Mark out and cut the straight return piece as shown...

STEP 15

...followed by the angled return piece
Glue and screw the sections, making sure that they still match the outlines on your base-board. DO NOT fix to the base board yet
Then repeat the whole process to construct a second assembly exactly the same as this one. These will be the base plate and top plate for your angled wall

STEP 16

Cut 5 lengths of CLS 376mm long
Fit the first length to your angled wall base plate exactly as shown...

STEP 16

...then fit the remaining lengths as shown below

STEP 17

Fit the top plate...

STEP 17

...and then fit the whole assembly to the existing structure
Check that you have met the standards for the task, if not ask your tutor to help you snag your stud wall (Snagging or remedial work is a normal part of the process and doesn't mean you have failed, you're just not finished yet!)
Once your stud wall jig is complete, make sure your tutor has checked it and then complete the sign off process
Make sure your name is on your work in PERMANENT MARKER, you will be using this jig for more site carpentry exercises
