Description
BACKGROUND OF THE PRESENT INVENTION
[0001] 1. Field of Invention
[0002] The present invention relates to a support frame, and more
particularly to a support frame for solar energy device.
[0003] 2. Description of Related Arts
[0004] With the rapid development of social economy, the reserves
of oil, coal and other non-renewable energy sources are getting
fewer and fewer, and the price is getting higher and higher.
Nowadays, solar energy as one of important clean energies is paid
more and more attention and widely used, such as a flat-plate solar
collector and a solar panel. Obviously, it is unavoidable to need
the support frame while installing and utilizing the above solar
energy devices.
[0005] The currently common support frame for solar energy device
is mainly made of aluminium alloy and angle iron. The aluminium
alloy support frame has a light weight and is convenient for being
transported. However, it needs additional devices, such as cement
columns, while fixed on the ground. In addition, the aluminium
alloy support frame has a higher manufacture cost and insufficient
structural strength. As a result, once encountering strong wind,
the aluminium alloy support frame is easy to be damaged, the
service life is affected accordingly. The angle iron support frame
has a sufficient structural strength, but poor corrosion
resistance, thus it is easy to be corroded and rusted while
long-term exposed to outdoors, the sun and rain. Accordingly, the
service life of the angle iron support frame is affected. In
addition, the angle iron support frame is manufactured by cutting
and welding and needs site welding so that the difficulty of
installation is increased.
[0006] Furthermore, for supporting a plurality of solar energy
devices, such as solar panels, the common solar energy support
frame is either assembled by a plurality of support members, or
formed wholly. The former wastes materials, increases cost and has
a bad stability, the latter needs redesigning for different amounts
of solar energy devices and can't be common used, thus increases
cost, and has a lower re-using rate.
SUMMARY OF THE PRESENT INVENTION
[0007] An object of the present invention is to provide a support
frame for solar energy device, which has a lower cost, corrosion
protection, long service life, higher structural strength, good
normability, is capable of site pouring and adapted for any amount
of solar energy devices.
[0008] Accordingly, in order to accomplish the above object, the
present invention provides a support frame for solar energy device,
comprising at least two support bodies, and at least two lintels,
each of which being provided between the two support bodies,
wherein the two lintels are adapted for supporting the solar energy
device, wherein each of the support bodies and each of the lintels
is made of reinforced concrete so as to reduce the manufacture
cost, increase the structural strength, prevent corrosion and
extend service life.
[0009] Each of the support bodies comprises two supporting columns,
and a transverse beam fixedly provided between two top ends of the
two supporting columns respectively, wherein two ends of each of
the two lintels are fixedly provided on a transverse beam of one of
the support bodies and a transverse beam of another adjacent
support body, respectively, the two lintels are spacedly arranged
with each other at a predetermined distance.
[0010] The two supporting columns have a different height so that
the transverse beam produces a tilt angle relative to the ground.
That is to say, the lintels define a supporting plane which
produces a tilt angle relative to the ground, in such a manner that
when the solar energy device is provided on the lintels, the solar
energy device produces a tilt angle relative to the ground for
receiving sufficiently solar energy.
[0011] Each of the support bodies further comprises a strengthened
beam fixedly provided between the two supporting columns for
strengthening a structural strength of each of the support bodies,
wherein the strengthened beam is parallel to the ground, one end of
the strengthened beam is fixedly provided at a top end of a lower
supporting column of the two supporting columns, in such a manner
that the strengthened beam, the transverse beam and a higher
supporting column of the two supporting columns define a triangle
so as to increase effectively the structural strength of each of
the support bodies.
[0012] Each of the support bodies and two lintels has a hollow
structure not only to strengthen a structural strength, but also to
reduce a weight.
[0013] Therefore, the support frame for solar energy device of the
present invention, made of reinforced concrete, has a lower cost,
corrosion protection, long service life, higher structural
strength, good normability, is capable of site pouring and adapted
for any amount of solar energy devices.
[0014] These and other objectives, features, and advantages of the
present invention will become apparent from the following detailed
description, the accompanying drawings, and the appended
claims.
BRIEF DESCRIPTION OF THE DRAWINGS
[0015] FIG. 1 is a perspective view of a support frame for solar
energy device according to a preferred embodiment of the present
invention.
[0016] FIG. 2 is an exploded view of the FIG. 1.
[0017] FIG. 3 is a side view of a support body of the present
invention.
[0018] FIG. 4 is a perspective view while a plurality of support
frames for solar energy device are assembled according to the
preferred embodiment of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0019] Referring to FIGS. 1 and 2 of the drawings, a support frame
for solar energy device according to a preferred embodiment of the
present invention is illustrated, in which the support frame
comprises at least two support bodies 1, and at least two lintels
2, each of which being provided between the two support bodies 1
and forming a support plane to place a solar energy device, such as
a solar panel, wherein each of the support bodies 1 and lintels 2
are made of reinforced concrete.
[0020] Because the elements of the support frame for solar energy
device are made of reinforced concrete, the support frame is
capable of site pouring and then assembling without worrying out
the lack of some elements. In addition, according to specific
requirements of construction site, the structure or size of the
support frame for solar energy device can be adjusted appropriately
to meet the requirement, so as to save the trouble of
transportation and reduce the cost. For example, the number of the
lintels 2 can be defined by concrete conditions, that is to say,
either three or four lintels 2 can be provided between the adjacent
two support bodies 1.
[0021] Referring to FIG. 3, each of the support bodies 1 comprises
two supporting columns 11, and a transverse beam 12 fixedly
provided between two top ends of the two supporting columns 11
respectively, wherein two ends of each of the lintels 2 are fixedly
provided at a transverse beam 12 of one of the two support bodies
and a transverse beam 12 of an adjacent support body respectively,
the lintels 2 are spacedly arranged with each other at a
predetermined distance. The two supporting columns 11 have a
different height so that the transverse beam 12 produces a tilt
angle relative to the ground, that is to say, the supporting plane
defined by the lintels 2 produces a tilt angle relative to the
ground, in such a manner that when the solar energy device is
provided on the lintels 2, the solar energy device produces a tilt
angle relative to the ground for receiving sufficiently solar
energy. It is worth to mention that the tilt angle can be
determined by latitude where the support frame for solar energy
device is provided.
[0022] The elements of the support frame for solar energy device
are made of reinforced concrete, the support frame has a good
normability, the mixed concrete has a plasticity to manufacture the
structures or elements with different sizes, so that the support
frame for solar energy device can be made correspondingly according
to specific size of the solar energy device and the latitude where
the solar energy device is provided.
[0023] According to the preferred embodiment of the present
invention, each of the support bodies 1 can be an integral forming,
that is to say, the two supporting columns 11 and the transverse
beam 12 are integrally formed so as to increase the structural
strength of each of the support bodies 1. The transverse beam 12 is
fixedly connected with the lintels 2 by expansion screws.
[0024] A bottom end of each of the supporting columns 11 can be
fixed on the ground by pouring or expansion screws. Furthermore, a
hole matching with a size of each of the supporting columns 11 can
be poured in advance on the ground, such that each of the
supporting columns 11 is capable of inserting directly into the
hole for being fastened on the ground. Accordingly, the
installation procedure is simplified and the installation
efficiency is increased.
[0025] Each of the two support bodies 1 further comprises a
strengthened beam 13 fixedly provided between the two supporting
columns 11 for increasing the structural strength of each of the
two support bodies 1. According to the preferred embodiment of the
present invention, the strengthened beam 13 is parallel to the
ground, and one end of the strengthened beam 13 is fixedly
connected with a top end of a lower supporting column of the two
supporting columns 11, such that the strengthened beam 13, the
transverse beam 12 and a higher supporting column of the two
supporting columns 11 define a triangle so as to increase
effectively the structural strength of each of the support bodies
1.
[0026] Each of the support bodies 1 and lintels 2 has a hollow
structure, so as to not only increase the structural strength, but
also reduce the weight of the support frame for solar energy
device, thus it is convenient for transportation.
[0027] Referring to FIG. 4, when a plurality of solar energy
devices are placed, namely, scale utilized, the number of the
support bodies 1 is added and the lintels 2 are provided between
the two adjacent support bodies 1. Here, the solar energy device is
sheet like in general, such as the solar panel. As a result, in
windy weather, the force applied to the solar energy device is very
strong, that is to say, the support frame for solar energy device
bears very great pressure or tension at this time. The material of
existing support frames can't bear great pressure or tension, such
as angle iron or aluminium alloy, however, the reinforced concrete
has a stronger structural strength, with a compressive strength
more than 35 MPa, a tensile strength more than 200 Mpa, wherein
reinforcing bar bears the tension, the concrete bears the stress.
Accordingly, in the light of actual situation, the user is capable
of increasing or reducing the support bodies 1 and lintels 2 based
on a primary support frame for solar energy device for increasing
or reducing solar energy devices, so as to facilitate the user and
reduce the cost.
[0028] It is worth to mention that the support frame for solar
energy device can be made of not only ordinary portland cement, but
slag cement, pozzolana cement, and fly ash cement. In order to
strengthen the viscosity and elasticity of cement, some cement
mortar additives can be added, such as the 107 glue (polyvinyl
formal) or white latex (polyvinyl acetate emulsion). In the
practical production, the special cement can be used to further
strengthen the support frame for solar energy device. A raw
material of the special cement mainly includes limestone, bauxite,
and some return of clinker (crystal seeds).
[0029] According to the present invention, the support frame for
solar energy device made of reinforced concrete is convenient for
drawing materials locally. The reinforced concrete structure is
made of sand, stone and other materials with a larger proportion
which are easy to be drawn locally. Furthermore, slag, fly ash and
other industrial waste are in favor of protecting environment, and
have a lower cost which is two-thirds of that of aluminium alloy
structure, and one half of that of angle iron structure.
[0030] Because the support frame for solar energy device is made of
reinforced concrete, it is not easy to be corroded, and is affected
less by rain and air corrosion so that it has a longer service life
which is more than fifty years according to general building
requirements.
[0031] In addition, the solar energy device is generally utilized
at the areas with great temperature differences, and the foundation
for mounting the support frame is generally made of concrete.
Temperature linear expansion coefficient of the reinforcing bar and
concrete is basically the same (the reinforcing bar is
1.2.times.10.sup.-5, the concrete is
(1.0.about.1.5).times.10.sup.-5). As a result, when the temperature
changes, the cohesion between the reinforcing bar and concrete will
not be damaged owing to too much deformation difference.
Accordingly, when the support frame for solar energy device made of
reinforced concrete is mounted on the foundation, the user will not
worry about the phenomenon of expanding with heat and contracting
with cold caused by temperature differences.
[0032] One skilled in the art will understand that the embodiment
of the present invention as shown in the drawings and described
above is exemplary only and not intended to be limiting.
[0033] It will thus be seen that the objects of the present
invention have been fully and effectively accomplished. It
embodiments have been shown and described for the purposes of
illustrating the functional and structural principles of the
present invention and is subject to change without departure from
such principles. Therefore, this invention includes all
modifications encompassed within the spirit and scope of the
following claims.
