 Bases
for Pumps, Blowers, Compressors, HVAC Units, etc.
Many years ago, we reduced the cost of concrete
bases by introducing KIP mountings. These mountings are nailed to the
inside of the contractor's wooden forms to provide side openings for the
springs that elevate the base and isolate the equipment. KIP bases are
structurally successful as the rigidity and strength of any base is dependent
on the depth and the reinforcing, and not on the perimeter steel.
Perimeter steel acts as a form for the concrete
and it provides a convenient means of attaching height-saving brackets
and packaging the reinforcing. While the KIP designs appear to be less
expensive, contractors prefer buying the complete package within the steel
form work as fewer trades are involved.
Traditionally, all vibration base manufacturers
used rolled beams or channels for these forms. The obvious reason was
availability as these materials could be bought in small quantities. Because
of your confidence in our company our volume has increased to the point
where it is possible for us to stock modular lightweight sections to more
efficiently provide forms without using structural members. The BMK design
is available in 6" and 10" depths and in 6" length increments in the smaller
sizes and 12" thereafter. Since a 10" modular base is more rigid and less
costly than an 8" structural base, we normally offer our 10" BMK even
though an 8" depth might meet a minimum specification. We must apologize
for our use of the letter "K" as the abbreviation for concrete. In our
early history, the letter "C" was used for "Castings". The code
name BMK stands for "Bolted Modular Koncrete".
Since the members are formed rather than rolled,
our engineers were able to call for greater thickness of material and
flange width as the sections became deeper and longer. All sections are
sufficiently rigid to hold the wet concrete without cross bracing. Any
rectangular or square base within the size limits of the formed sections
can be assembled from stock by bolting these members to suitable corner
brackets.
BMK bases can be assembled with templates, cast
iron anchor bolt sleeves and anchor bolts. Reinforcing can be built in,
and in the case of blower bases, we can provide the adjustable motor slide
rails.
Thus, we have kept our original concept of the
complete package and we have reduced weight by eliminating the needlessly
heavy structural members that do nothing for base integrity. All designs
have been destruction tested using full scale models in the most unfavorable
long and narrow configurations. Safety factors are a minimum of three
to one. We continue to recommend a depth of 1/12 the longest dimension
of the base, with a minimum depth of 6 inches.
The advantage to the specifying engineer and
the owner is the much improved appearance of the smoothly formed contours
and the baked enamel finish. There are very few exposed welds. The contractors
find these bases easier to handle and when the overall dimensions are
too large to fit through building openings, they can be shipped knocked
down and quickly assembled. The modular submittal drawings are excellent
and delivery time is greatly reduced by shipments from depots throughout
the country and the world.
BMK bases are most commonly used with SLF spring
mountings from the minimum 3/4", 1 1/2", 2 1/2" and 3 1/2" deflection
groupings. They are equally adaptable to type C, SSLFH and SLR spring
mountings or Air Springs and ND Neoprene mountings. They can be furnished
as simple frames with closed corners when no isolation is required, or
when isolation is placed under the base. These bases will also accommodate
type Z-1011 or Z-1225 seismic snubbers.
BMK bases are another step forward in vibration
control technology.
