Locate
the points on the corner boards by drawing a cord from one board to the other,
bringing it directly over the nails at the two corners on the same line; these
points should be accurately marked on the board by a notch, or by cutting a
shallow groove with a concrete saw. This cord represents the outside line of
the concrete foundation; the inside line will be indicated by measuring in a
distance equal to the thickness of the proposed foundation and stretching a
cord between these two points: Carefully mark these points on the board in some
way different from the marks showing outside lines. A plumb-bob suspended from
these lines to the ground will indicate the line of excavation. A form made
like Fig. A, Plate 33, measuring 10 or 12 inch on each side at the top and a
little more at the bottom, being sloped so that it may be lifted easily off the
concrete, is a very useful form to make and keep around. Concrete piers for the
foundation of small buildings are easily made with this type of form. The top
level of the form can be regulated by putting blocks under the handles of the
concrete form.
The hole for the base of the concrete pier should be 6 or 8 inch
bigger each way than the form, thus allowing the concrete to spread as shown.
Concrete forms for taller concrete piers should be very strongly braced all
around each side by pieces of 2 inch x 4 inch material spiked together and
spaced about 18 inch apart. Concrete columns over 6 ft. in height should have
yokes of 4 inch x 4 inch material, held together by bolts and side pieces held
in position by wedges. These should be spaced about 20 inches apart. These concrete
columns should be reinforced with 3/4 inch iron rods. A concrete column which
is to carry no great weight may have the concrete forms removed inside of 48
hours. Fig. B, Plate 33, shows a simple box form for concrete column footings.
The drawing is self-explanatory. Fig. C, Plate 33, shows form and method of
casting a concrete foundation for a gasoline engine. The foundation consists of
a block of concrete resting on a firm sub-base, with anchor bolts properly set,
by means of which the engine is held in place. Concerns manufacturing engines
usually state the length of anchor bolts, the location in regard to each other,
and the size of the concrete foundations needed for the various sizes of
machines. Plate 34 shows three different types of concrete foundations. Sometimes
because of the nature of -the soil, or possibly because a team and scraper are
used in removing the earth, the concrete walls of the excavation cannot be kept
perpendicular. In such cases concrete forms must be placed for that portion of
the foundation below ground as well as for the portion above, if there be any.
Unless
concrete forms for the whole foundation are to be put up at one time, it will
be best to build them flat on the ground, in units of convenient length, and
then erect them in place. By having the concrete forms constructed in this way
they may be removed and used again, with the minimum amount of concrete damage
to the lumber. In building concrete forms flat the stringers should be
carefully leveled and the uprights and sheathing carefully placed in their
correct relative positions, otherwise the concrete forms will be askew when
erected. If the concrete forms are to be built in position, first place the
stringers shown at the bottom of the inner form (Fig. A), so that when the
upright 2x4's and the sheathing are in place, the inside face of the sheathing
will be in line with the inner face of the proposed Concrete wall. .Nail the
lower end of the uprights to the stringer and attach the top board of the
sheathing to hold the vertical 2x4's the proper distance apart. The frame must
now be plumbed carefully and held in place by the braces extending between the
upper end of the 2x4's and stakes driven in the ground.
