TITLE: DUAL PRESTRESSED ROPE BEAM FIELD
[0001] It is related to the fields of:
(1) Structural/ Mechanical Engineering.
DESCRIPTION
1.1 Drive Beam
[0003] A Drive Beam is a beam functional as both a drive shaft and a beam. It is capable
to both twisting moments and bending moments.
1.2 The Centred Prestressed Rope Beam (CPRB) (Figure 1).
[0004] The CPRB is developed for structures of energy systems such as floating energy
systems and grounding energy systems, including wave energy systems and solar
tracking systems. It is also applied for systems of floating objects.
[0005] The development purposes of the CPRB related to its structure are:
(1) These energy systems require their structures to be light,
(2) Lengths of its beams, (floating) posts, drive shafts or any type of hollow tube
components may need to be long enough.
[0006] Components and arrangements of the CPRB:
(1) A Hollow Tube (#2). The Hollow Tube might be a (hollow) cylinder, or square,
or rectangular, or polygon (pentagon, hexagon, heptagon, octagon...).
(2) A number of Tensional Ropes/ Cables (#13).
(3) A number of Circular Rope Supports (#12). The shape of the Circular Rope
Supports is just small enough to fit inside the Hollow Tube. The gap between
the installed Circular Rope Supports and the Hollow Tube needs to be small
enough for installation and operation. The thickness of the Circular Rope
Supports must be enough for structural stability. The Circular Rope Supports
(#12) are secured to the Tensional Ropes/ Cables (#13).
(4) The Tensional Ropes/ Cables are stressed and positioned inside the Hollow
Tube. Its two ends are secured to the two ends of the Hollow Tube.
(5) If the number of Tensional Ropes/ Cables is more than one, these Tensional
Ropes/ Cables are distributed closest to the wall of the Hollow Tube, depending on loads the CPRB bears. Figure 1 (c) presents some cases of two, three orfourTensional Ropes/ Cables distributed.
[0007] Operations of the CPRB:
(1) The CPRB can work as a beam, a (floating) post, a drive shaft or a Drive Beam
in structures of energy systems. The Tensional Ropes/ Cables improve bending
resistance of the Hollow Tube while keeping the CPRB to be light and capable
to be assembled fully at factories. Its smaller size and weight help for
transportation and onsite installation.
(2) Bending resistance of the CPRB is improved thanks to contributions of the
Tensional Ropes/ Cables which make the tensional/ compressional areas of
cross sections of the Hollow Tube to be improved: the tensional area of the
wall of the Hollow Tube is reduced and its compressional area is enlarged. This
leads to the tensional area of the CPRB (combined from the Hollow Tube and
the Ropes/ Cables) and the compressional area of the CPRB (enlarged in
comparison with the Hollow Tube alone) are both to be more capable for
tensional and compressional forces. Thus, bending resistance of the Hollow
Tube is improved using prestressed Tensional Ropes/ Cables fitted inside.
[0008] Tensional Ropes/ Cables can help long CPRBs to be strait enough.
1.3 The Compressional Beam (Figure 2)
[0009] It is a beam, a group of beams, a frame or a combined frame-beams that is
compressional.
[0010] The main function of the Compressional Beam in proposed structures such as
the Surrounding Prestressed Rope Beam is to bear loads causing internal
compressional forces. It can also be used as a Drive Beam if its cross section is
appropriate for twisting moments.
[0011] The Compressional Beam is a main part of the Dual Prestressed Rope Beam
(DPRB).
[0012] There are three types of Compressional Beams:
(1) Type 1: Beam only (Figure 2 (a))
(2) Type 2: Frame only (Figure 2 (b))
(3) Type 3: Frame-Beam (Figure 2 (c))
1.4 The Rope/ Cable Supporting Clamp and the Beam's Crossed Rope (Figure 3)
[0013] The Rope/ Cable Supporting Clamp (#1) is the part that mounts ropes/ cables/
bars/ beams and secures them to Compressional Beams to form a Surrounding
Prestressed Rope Beam (SPRB).
[0014] The Beam's Crossed Ropes" (#5 in Figure 3 (d)) are crossed ropes connecting
every two consecutive Rope/ Cable Supporting Clamps.
1.5 The Surrounding Prestressed Rope Beam (Figure 3)
[0015] The Surrounding Prestressed Rope Beam (SPRB) is developed in order to bear
light weights such as solar panels over long spans subjected to dynamic loads caused
by winds or rotations of the SPRB, which require the SPRB to be capable to multiple
directions of loads.
[0016] The SPRB comprises a Compressional Beam with prestressed Ropes/ Cables
distributed along and around to improve bending resistant in all directions whereas
its weight is light. Furthermore, if the Compressional Beam is also a Drive Beam, the
SPRB is capable to rotate masses mounted on it such as solar panels.
[0017] The word "Rope" mentioned here implies rope, cable, bar or even beam, which
are capable to tensional force. However, the flexibility and light weight of rope or cable
are preferred.
[0018] The SPRB composes of:
(1) Compressional Beams positioned inside as the core. These Compressional
Beams are responsible for compressional forces.
(2) Beam's Surrounding Ropes, which are ropes distributed around the
Compressional Beams. These Beam's Surrounding Ropes are responsible for
tensional forces.
(3) Rope/ Cable Supporting Clamps distributed along the Compressional Beams.
(4) Beam's Crossed Ropes connecting every two consecutive Rope/ Cable
Supporting Clamps.
[0019] The Compressional Beams and Ropes are secured together via the Rope/ Cable
Supporting Clamps.
[0020] Characteristics of the SPRB:
(1) capable to bear dynamic loads in different directions, including wind loads and
earthquakes.
(2) light and capable to reach long spans.
(3) developed to bear light weights such as solar panels.
(4) capable to work as a drive shaft/Drive Beam for rotating arrays of solar panels.
(5) Developed to be a type of linkages of 3DFPNFO (The System of Three
Dimensional Flexible Porous Net of Multiple Floating Objects), which might
require to maintain constant distances between every two connected points
of the two consecutive floating objects.
(6) The Beam's Surrounding Ropes are able to be stressed further differently and
separately in order to adjust the Compressional Beam in the most possible
straight shape under all cases of loads and Angles of Rotation.
(7) The quantity of Ropes and their specifications depend on different
circumstances such as loads and directions of loads. The quantity of Ropes can
be one or more. The quantity of Compressional Beams can also be one or
more. Some Ropes can be replaced with straight beams or curved beams or
bars.
(8) Cross sections of a SPRB are different in shapes and sizes, depending on how
loads are distributed alongthe SPRB. Thus, the Rope/Cable Supporting Clamps
of a SPRB are different accordingly.
(9) Functions of the Rope/ Cable Supporting Clamps, which is a part of the SPRB,
are included in the SPRB: the Beam's Surrounding Ropes can be stressed further or less using a mechanism integrated in the Rope/ Cable Supporting
Clamps; The Beam's Surrounding Ropes can also be repositioned closer to or
further from the Compressional Beam using the "Slide and Lock" Mechanism
integrated in the Rope/ Cable Supporting Clamps.
(10) The SPRB can be continuous over supports.
[0021] This type of light weight beam, the SPRB, is developed for long span structures.
The SPRB aims to bear more loads while saving cost for materials, transportation,
installation and reducing number of posts supporting beams.
[0022] The SPRB is used for any kind of structures, especially energy systems such as
wind, solar and wave based, either floating or grounding, with or without solar
tracking systems. It is also used for any kind of floating structures, especially flexible
floating structures for coping/ adapting with large displacements caused by waves.
[0023] If the SPRB is used for bending moments only, the profile of its Compressional
Beam can be a frame or in the shapes of L, C, Z, T, H, I, Round and Polygon (such as
square, pentagon, hexagon, heptagon, octagon).
[0024] If the SPRB is used for both bending and twisting moments, the profile of its
Compressional Beam can be in the shapes of Round or Polygon (such as square,
pentagon, hexagon, heptagon, octagon).
[0025] If the SPRB does not need to be capable to twisting moments for rotating, its
Compressional Beams does not need to include the function of twisting. In this case,
the SPRB is still capable with features to be applicable in solar energy systems without
tracking, eitherfloating or grounding, such as agricultural solar or floating solar energy
systems which require cheaper structures and long spans.
[0026] Figure 3 demonstrates some types of the SPRB.
[0027] Figure 3 (al), (a2), (a3) and (a4), representing Type A of SPRB: this type of SPRB
is based on a single Compressional Beam which is also a Drive Beam. The type is
appropriate for structures of energysystems (solar, wave, wind)with orwithoutsolar
tracking systems, ether floating or grounding.
[0028] Figure 3 (b1), (b2), (b3) and (b4),representing Type B of SPRB: this type of SPRB
is based on a single Compressional Beam which is a frame. The type is appropriate for
structures of energy systems (solar, wave, wind turbines) without solar tracking
systems, ether floating or grounding.
[0029] Figure 3 (c1), (c2), (c3) and (c4), representing Type C of SPRB: this type of SPRB
is based on a Compressional Beam which is composed of a Drive Beam and a frame.
This type is appropriate for structures of energy systems (solar, wave, wind turbines)
with or without solar tracking systems, ether floating or grounding. It is more
appropriate for longer beam bearing heavier loads. It is also more capable to dynamic
loads such as earthquake than the SPRB Type A.
[0030] Figure 3 (d) demonstrates how to stabilise two consecutive the Rope/ Cable
Supporting Clamps using Beam's Crossed Ropes (#5). These ropes are important in
maintaining the stability of the SPRB.
[0031] The SPRB can be enhanced with Centred Prestressed Rope Beam (CPRB)s
integrated.
1.6 The Dual Prestressed Rope Beam (DPRB)
[0032] The DPRB is composed from the Surrounding Prestressed Rope Beam (SPRB)
and the Centred Prestressed Rope Beam (CPRB). There are three types of DPRBs:
(1) Type 1: Prestressed Ropes/ Cables are externally secured to Compressional
Beams. The Prestressed Ropes/ Cables are distributed around the
Compressional Beams. Thus, Type 1 is the Surrounding Prestressed Rope Beam
(SPRB).
(2) Type 2: Prestressed Ropes/ Cables are internally secured to Compressional
Beams. The Prestressed Ropes/ Cables are distributed inside the
Compressional Beams. Thus, type 2 is the Centred Prestressed Rope Beam
(CPRB).
(3) Type 3: Prestressed Ropes/ Cables are internally and externally secured to
Compressional Beams. Type 3, which is the combination of the SPRB and the
CPRB, is the full version of the Dual Prestressed Rope Beam (DPRB).
[0033]The Prestressed Ropes/Cables helptoenhance bending resistance of the DPRB.
It can be produced at factories by skilled workers and equipment, leading to saving
costs of manufacturing, transportation and onsite installation.
[0034] The DPRB is developed for structures of energy systems such as floating energy
systems and grounding energy systems, including wave energy systems and solar
tracking systems. It is also applied for systems of floating objects.
