Give a literary translation of the first four steps of how to put a timber staircase together from the timber pieces
|
|
7. You’ve misheard the information. Make it more exact, putting questions:
Example: A: Timber staircase usually consists of two strings, treads and risers, a balustrade and a handrail.
B: What does timber staircase consist of?
1. Reinforced concrete staircases are increasingly popular and usually cast in situ on formwork.
2. The first principle in staircase design is that a person should be able to move comfortably from one step to another.
3. Each riser in a flight of stairs must be the same height.
4. Insert and glue two wedges in each tread to strengthen the joint.
5. Transport the complete staircase to the building site and put it into the building.
8. Match the parts of a staircase to its definitions. Figure given in the text may help you:
| 1. baluster | a) an inclined rail that follows the slope of the stairs, which is either fixed to a wall or supported on balustrade |
| 2. balustrade | b) the vertical surface of a step |
| 3. flight | c)a stout vertical post at one end of the outer string. its function is to support the inclined handrail for a timber staircase |
| 4. handrail | d) the protection erected on the outer edge of a staircase to prevent anything or anyone falling off the edge |
| 5. landing | e) the vertical distance between the tops of adjacent treads |
| 6. newel | f) the part of the tread that projects beyond the face of the riser |
| 7. nosing | g) the horizontal surface of a step where the feet are placed |
| 8. rise | h)the infill between the handrail and the string. For safety reasons, the gaps between the uprights on the balustrade must be less than 100 mm apart. it can also be wide rails that run parallel to the string with a handrail supported by intermediate balusters. they can be spaced more widely |
| 9. riser | i) the level space that breaks up the vertical incline of a flight of stairs |
| 10. string | j)the side support for a flight of timber steps. the strings are two timber pieces that form the sides of a staircase, which measure about 38×250 mm. the treads and risers are usually fixed into strings in 12 mm slots, which are trapped to take wedges |
| 11. tread | k)a series of steps between floors or a floor and landing |
