[0001] The present invention relates to prefabricated preassembled sections, which are erected
in the work site and are secure with screws and nuts through the specially located
holes on the platform element and top plates of the supported columns. The prefabricated
preassembled sections have excellent constructibility, high earthquake resistance,
a wide ground and first floor space due to the unique location of support columns
spaced 5500mm apart. More importantly, the present invention does not require any
foundation as well as horizontal and vertical beams between the support columns.
[0002] An other aspect of this invention there is provided a method of erecting the modular
structure from a plurality of prefabricated units of modular construction.
[0003] Portable parking structures have been already provided in the prior art. Generally,
there is great demand of parking space due to the increasing number of cars in urban
areas.
[0004] The prefabricated sections are easily erected and dismantled.
[0005] The prefabricated parking system gives the possibility of easily extending or reducing
the number of cars to be parked.
[0006] The present invention due to the unique designed of the three different types of
support columns and platform elements has its objective to provide a multi-storey
building which can be quickly and easily erected from the prefabricated components
which are suitable for providing temporary multi-level car parking or a temporary
building such as temporary ware house.
[0007] Due to the modular system and no need of foundation the structure can be assembled,
dismantled or rearranged very easily and in a very short time without loosing or destroying
parts. That means that there is the possibility to rent the system and not being obliged
to buy it.
[0008] The construction is based on the latest European technical standards, so there is
no problem to get a licence for using the system in the EC-countries or countries
outside the EC, who accept the European technical standards.
[0009] The system has, compared to the patents US 5826381, WO 9945220 and US 4800694, the
following differences and advantages:
[0010] Easy assemblage and dismantling of the prefabricated parts because of their standardized
dimensions and shape. The easy assemblage of the self-supported prefabricated platforms
gives the ability to expand the existing parking places and also to change the arrangement
(layout) of the parking places.
[0011] Due to the unique design of the columns (2), (3) and (4) and platform elements (1)
the self-supported prefabricated platform do not require any support or framework.
[0012] The lack of horizontal and vertical beams (bracings) between the columns allows easy
circulation of the vehicles on the ground floor.
[0013] For the support of the columns to the ground there is no foundation construction
needed. In places with high seismic activity special anchors are provided to secure
the structure to the ground.
[0014] The columns give the ability to adjust their height ±150mm, for the platform to be
flat. This means that even on not complete flat or uneven ground a smooth and plane
parking platform is possible.
[0015] The construction materials can be standardized steel profiles, shaped iron plates
or non-steel materials.
[0016] The ascent and descent ramps for the upper parking surface have an incline slope
of 20% which is gradually reduced to 0%, with a preferable slope of 14% reduced to
7% reduced to 0%. Protection bars on both sides are provided.
[0017] On the top floor there are special sunroofs.
[0018] There is also the ability to increase the height of the construction to be more than
one floor. In case of two floors or more, there is certainly the need to have foundations
below the columns.
[0019] Perimetric protection bars on the top floor are provided.
[0020] There is no need to use the land permanently as parking area, because this construction
consists of prefabricated modules and can be placed in another area, if this is required.
[0021] The structure, as designed, can withstand loads from snow, ice, earthquake or crowded
humans as well as the parked cars. This design meets and exceeds the European technical
standards.
[0022] For the structure to be more economical (less weight) and still withstanding all
the loads as described above, it can be assembled as shown in Figure 5, so that the
internal forces are distributed more evenly to each member (rearranging the prefabricated
modules).
[0023] According to this invention the self-supported prefabricated parking structure comprises:
a) three types of support columns with adjustable height,
b) self-supported prefabricated platform element with reinforced steel plates with
furrows on top to support the weight and eliminate slippage of the vehicles parked
and humans on top of the platform. Each platform elements has a maximum of 40 holes
specially located at the corners and center of the steel frame,
c) a ramp for driving up and down, with an incline slope of 20% reduced to 0%,
d) a step like staircase,
e) side and top covers (sunroofs),
f) metal rails around the perimeter of the parking structure on the first floor for
protecting vehicles and humans, and for parametrically reinforcing the parking structure.

[0025] Figures 1 and 1a illustrate a perspective view of a self-supported modular vehicle
parking structure according to the present invention. Figures 2 and 3 illustrate a
cross sectional view A and B, and C and D of Figure 1a which is utilized as a parking
station.
[0026] The first basic elements of the self-supported prefabricated parking structure of
Figures 1 and 1a are the three types of specially designed columns (2), (3) and (4)
for central, edge and corner locations. Columns (2), (3) and (4) are shown in Figures
6, 7 and 8. Each column consists of two square hollow steel parts. Column (2) consists
of parts (12) and (13), column (3) consists of parts (12) and (14) and (4) consists
of parts (12) and (15). Parts (12) and (13), (12) and (14), and (12) and (15) have
an easily adjustable height (telescope) up to ±150mm.
[0027] The support columns (2), (3) and (4) attain flatness to the platform element (1)
for uneven grounds through specially located holes 10mm apart, and jointed with pins
(25) in the support column (2), (3) and (4).
[0028] With references to Figures 4 and 5 also, the illustrated self-supported vehicle parking
structure as shown in Figure 1 is assembled in the form shown in Figures 1 to 5 by
assembling several kinds of assembly elements but it is basically comprises of six
types of assembly elements shown in Figures 6, 7, 8, 10, 13, 14, 15 and 16.
[0029] As will be seen from Figures 6 to 8 the square hollow steel part (12) is welded to
the base plate (26).
[0030] Further more in cases where there is high seismic activity, base plate (26) of columns
(2), (3) and (4) can be bolted to the ground with high strength steel anchors (16)
shown in Figure 9 through the eight wholes, which are provided.
[0031] On the vertical square hollow steel part (13) there is a welded top plate (21) supported
with stiffeners (22) and (23). These stiffeners (22), (23) and the plate (21) yield
the bending moment resistant connection between the columns (2) and the platform element
(1). Further, plate (21) of column (2) has a maximum of thirty-two holes used to be
bolted to the platform element (1).
[0032] The construction of columns (3) and (4) is based on the same idea and function with
the central column (2). The main differences being, that the top plate (24) of column
(3) and top plate (24a) of column (4) is designed differently, depending on the system
location of the column (3) and (4).
[0033] Further more, top plate (24) of column (3) has a maximum of twenty-six holes used
to be bolted to the platform element (1). Top plate (24a) of column (4) has a maximum
of twenty holes used to be bolted to the platform element (1).
[0034] Columns (2), (3) and (4) are specially designed so, that they can withstand all the
loads from the parked vehicles and people with out requiring additional foundation
on the ground.
[0035] Column (2), (3) and (4) are placed 5500mm apart and are used to hold the weight of
the structure as illustrated in Figure 1. Columns (2), (3) and (4) are stabilized
to the ground by special anchors (16), as shown in Figure 9, to withstand horizontal
forces. Depending on the system layout and the earthquake area, where the system is
erected, the number of these anchors (16) varies from eight down to zero. However,
for places with low seismic activity anchors (16) are not needed. Instead a sheet
of rubber or plastic or other friction increasing material is provided on the bottom
surface of the support columns (2), (3) and (4) which makes contact to the ground.
[0036] The second preferred feature of the self-supported prefabricated parking structure
according to this invention is the design of a plurality of platform elements (1).
The dimensions of platform elements (1) as illustrated in Figure 10 are 2750mm×5500mm.
Platform element (1) is made from UPN profile (or bended steel plate) (17), which
creates an "integrated frame".
[0037] Along the length of the platform element (1) supporting beams (18) from L-profile
or bended steel plate are welded to the platform element (1). The top of the platform
element (1) is made from steel plate (19) with furrows in order to eliminated slippage
of vehicles and people. Platform element (1) is designed symmetrically so that it
can be placed at all points of the parking structure and in different directions.
Each platform element (1) has a maximum of 40 holes specially located at the corners
and center of the steel plate (19).
[0038] Figures 4 and 5 illustrate the different arrangements of platform elements (1). Due
to the possibility of different arrangement of platform element (1) it is possible
to use profiles of smaller crossections. Thus, a lighter construction is achieved
and therefore lower cost.
[0039] Figures 11 and 12 illustrate a connection detail of platform element (1) of the second
embodiment shown in Figures 1 and 10 with columns (2) and or (3) and or (4) with intermediate
joint (5). The connection is made by aligning the holes (already provided) of the
platform element (1) with those of the top plates (21), (24) and (24a) of support
columns (2), (3) and (4).
[0040] The third main part of the self-supported prefabricated parking structure is the
ramp for driving up and down as illustrated in Figure 13. The width of the ramp is
2500mm to 5500mm (or more), to allow double-lane traffic of cars. The ramp comprises
prefabricated columns (2), (3) and (4), platform elements (1), ramp parts (6) and
(7), and railings (9).
[0041] The ramp is designed with an inclination slope of 20% gradually reduced to 0%, with
a preferable slope of 14% reduced to 7% to 0%.
[0042] Figures 14 and 15 illustrates the central sunroof (10) and edge sunroof (11).
The edge sunroof (11) shown in Figures 1 and 14 comprises of roof columns (30), horizontal
beams (29), plurality of purlings (27), which are supported to the horizontal beams
(29) with U-bolts (28), and a sun proof lightweight net (20).
The central sunroof (10) shown in Figures 1 and 15 comprises of two horizontal beams
(29) on each column (30), plurality of purlings (27) supported by the horizontal beams
(29) with U-bolts (28), a sun proof lightweight net (20) and plurality of columns
(30).
The main difference between the edge sunroof (11) and the central sunroof (10) is
that the central sunroof (10) has two horizontal beams (29) on each column (30).
[0043] Figures 1 and 16 illustrates the perimetric protection railing (9). The railing (9)
is designed to protect cars and people from falling down from the parking platform.
Railing (9) is also a static main part of the system. The U-beam (31) shapes together
with the platform elements beam (17) a double U-beam (I-beam) to withstand the horizontal
perimetrical forces resulting from earthquake, wind loads, etc.
