An Overview Into Merrimack Town In New Hampshire A
facing, on the part of the concrete sidewalk exposed to wear, on thick finish,
will improve the wearing qualities of the Concrete curbing. There are two
general types of concrete curb used—a concrete curb rectangular in section, and
a combined concrete curb and gutter; both types are shown in Fig. 83. The concrete
foundation for either type is constructed in the same manner. Both these types
of concrete curb are made in place or molded and set in place like stone concrete
curb, but the former method is preferable. A metal corner is sometimes laid in
the exposed edge of the concrete curb to protect it from wear. The construction
of the rectangular section is a simple process, but requires care to secure a
good job. This is usually, about 6 inches wide and from 20 to 30 inches deep.
After the concrete foundation has been properly prepared, the forms are set in
place. Fig. 84 shows the section of a concrete curb 6 inches wide and 24 inches
deep, and the forms as they are often used. The forms for the front and back
each consist of three planks 1 inches thick and 8 inches wide, and are surfaced
on the side next the concrete. They are held in place at the bottom by the two
2 by 4-inch stakes, and at the top the stakes are kept from spreading by a
clamp. A sheet-iron plate inch thick is inserted every 6 feet, or at whatever
distance the joints are made. After the 1'x8" concrete has been placed and
rammed, and has set hard enough to support itself, the plate and front forms
are removed, Forms for constructing and the surface and top are finished smooth
with a trowel; the corner being rounded with a concrete edger as shown in Fig.
85. The joint is usually plastered over, and acts as an expansion joint. The
forms on the back are not removed until the concrete is well set. If a mortar
or granolithic finish is used, a piece of sheet iron is placed in the form 1x6'
one inch from the facing, and mortar the sheet iron and the front form and the
coarser concrete is placed back of the sheet iron sheet iron is then withdrawn
and the two concretes thoroughly tamped. Fig. 86 shows the section of a
combined concrete curb and gutter, and the forms that are necessary for its
construction. This combination is often laid on a porous soil without any
special concrete foundation, with fair results. A 1-inch plank 12 inches wide
is used for the back form, and is held in place at the bottom by pegs. The
front form consists of a plank 17 by 6 inches, and is held in place by pegs.
Before the concrete is placed; two sheet-iron plates, cut as shown in the
figure, are placed in the forms, six feet to eight feet apart. After the
concrete for the gutter and the lower part of the concrete curb is placed and
rammed, a lj-inch plank is placed against these
plates and held in Place by screw clamps (Fig. 86). The upper part of the concrete
curb is then molded. When the concrete is set enough to stay in place, the
front forms and plates are removed, and the surface is treated in the same
manner as described for the other type of concrete curb. The cost of concrete
curb will depend upon the conditions under which it is made. Under ordinary
circumstances, the contract price for rectangular concrete curbing 6 inches
wide and 24 inches deep will be about $0.60 per linear foot; or $0.80 per
linear foot for concrete curb 8 inches wide and 24 inches deep. Under favorable
conditions on large jobs, 6-inch concrete curbing can be constructed for $0.40
or $0.45 per linear foot. These prices include the excavation that is required
below the street grade. The cost of the combined concrete curb and gutter is
about 1.0 to 20 per cent more than that of the rectangular concrete curbing. In
addition to having a larger surface to finish, the combined concrete curb and
gutter requires more material, and therefore more work, to construct it. The
theory of flexure in reinforced concrete is exceptionally complicated.
