Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a solar panel supporting system and a constrcution method using the same,

The present invention relates to a cable support system for a solar panel, and more particularly to a system for supporting a plurality of solar panels using a cable.

Photovoltaic power generation is generally accomplished by installing a solar panel, which is a solar cell unit that converts sunlight to electrical energy. As the demand for such photovoltaic power generation increases, technologies for performing photovoltaic generation by utilizing the upper layer structures of a general private house or a building are widely spread.

Meanwhile, in recent years, there have been researches and developments of apparatuses for supporting solar panels using cables with low material cost and easy installation.

For example, Korean Patent Registration No. 10-1004108 discloses a solar panel fixing device using a steel wire as shown in FIG.

However, the cable structure according to the related art has a complicated structure, which is difficult to apply to the outer wall of a building.

Therefore, when a solar panel is applied to an outer wall of a typical building, an installation method using an anchor hole, a steel bracket, or the like is applied. However, there is a problem in that the construction method is inevitably damaged in the boring process, and the construction is complicated and the installation cost is high.

In addition, the construction method has a problem that the load of the panel system is increased due to the self weight thereof, and the stability of the structure is deteriorated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a cable supporting system for a solar panel according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a view showing a concrete embodiment of a cable supporting system of a solar panel according to the present invention, and FIG. 3 is a view showing a support base according to a specific embodiment of a cable supporting system of a solar panel according to the present invention FIG. 4 is a cross-sectional view showing another example of a support base according to a specific embodiment of a cable supporting system for a solar panel according to the present invention.

The cable supporting system of the solar panel according to the present invention can be applied to various types of building superstructures such as an inclined house roof structure and a slab roof structure, but the principle is the same. I will explain.

2, the cable supporting system for a solar panel according to the present invention includes a net cable 100 for supporting a solar panel P, and a cable support 100 connected to the end of the net cable 100, A main cable 200 for generating tensile force on the net cable; and a fixture for tightening an end of the main cable 200 to maintain a tension state.

The net cable 100 includes a cable main body 120 disposed on the top surface of the roof R in a crossing manner and a connecting hole 140 formed in a ring shape at the end. That is, the cable main body 120 is arranged on the upper surface of the roof R to support the solar panel P.

The installation conditions of the net cable 100 may be variously configured according to the shape and size of the top surface of the building, the tensile strength of the net cable, the installation environment, and the like.

In addition, a ring-shaped connecting hole 140 is formed at the end of the cable main body 120 so that the main land cable 200 passes through. For example, the connector 140 may be formed in a ring shape at an end of the cable main body 120. The connector 140 may be formed in a variety of shapes such that the main cable 200 penetrates.

In this case, the formation of the ring shape means that the cable end is folded for a certain period and the middle part of the cable is joined or bundled to form a ring shape, instead of joining separate components on the cable. In addition, the connector 140 may be a separate component formed as an annular member at the end of the cable body 120.

Also, the landing gear cable 200 is passed through the connector 140. That is, a plurality of connectors 140 installed on the side of the roof R are connected to the main land cable 200. As the hoist cable 200 is tensioned, tensile force is applied to the cable body 120.

At this time, the main accessory cable (200) includes a fixture (220) for tightening an end portion to maintain a tension state. That is, the fixture 220 maintains the tensile force of the main island cable 200 in a constant state. In addition, the shape of the fixture 220 may be variously used depending on the type of the main land cable 200, the use conditions, and the like.

For example, the fixture 220 can be applied with a fixture 220 in the form of a fixed clamp for simply fixing both ends of the master cable 200 in a state where the master cable 200 is pulled, A turnbuckle type fixture 220 may be applied.

A support base 300 for spacing the cable main body 120 from the bottom surface of the roof R is installed at an intersection of the cable main body 120. The support base 300 will be described later in detail.

2, when the cable supporting system of the solar panel according to the present invention is installed on the roof R having an inclination, the main land cable 200, which is arranged side by side with the inclined roof R, And a supporter 800 for supporting the main land cable 200 at the inflection point of the main land cable 200. [

Therefore, the supporter 800 supports the main land cable 200 in the same shape as the inclination of the roof R. In addition, the shape and the coupling method of the supporter 800 may be variously formed according to the installation environment.

Hereinafter, the structure of the support base described above with reference to FIGS. 3 and 4 will be described in detail.

3, the support base 300 constituting the cable support system of the solar panel according to the present invention includes a first support 400 having an insertion groove on which the net cable 100 is seated, A second support 500 coupled to a lower portion of the first support 400 and a buffer unit 600 disposed inside the first support 400 or the second support 500, And a support clamp 700 coupled to an upper end of the first support 400.

At this time, the first support 400 has a protrusion 440 protruding from the upper surface 422 of the support. Here, the protrusion 440 is for forming an insertion groove 444 into which the net cable 100 is inserted.

It is preferable that the shape of the insertion groove 444 is formed in a cross shape to correspond to the cross shape of the inserted net cable 100.

On the other hand, a thread is formed on the outer side portion 446 of the protrusion 440 and is coupled to the support clamp 700. That is, the support clamp 700 prevents the cable body 120 inserted into the insertion groove 444 from coming off. At this time, it is preferable that the support clamp 700 is formed in a shape corresponding to the upper end of the first support 400.

Here, the coupling method of the support clamp 700 and the first support 400 may be variously configured by screwing or press-fitting.

The second base 500 is coupled to the lower portion of the first base 400. At this time, a slip prevention end 540 is formed at the end of the main body 520 constituting the second support 500. The slip prevention end 540 is formed of a high friction material to prevent the second bearing 500 from slipping from the bottom surface.

Here, the high-friction material generally means an elastic material or a polymer-based polymer, but it can be easily replaced with a material such as wood according to the requirements of a construction site.

The support base 300 includes a buffer unit 600 provided inside the first base or the second base. At this time, the buffer unit 600 buffers the impact load generated between the cable main body 120 and the bottom surface. The buffer unit 600 may be formed by using an elastic member (first embodiment), a cylinder Examples) and the like.

Hereinafter, an embodiment using an elastic member will be described first.

The first embodiment of the shock absorber unit 600 may include an elastic member that supports the first and second bases 400 and 500 by an elastic force. At this time, various types of springs can be applied to the elastic member.

Next, a second embodiment of the buffer unit 600 will be described.

4, the second embodiment of the shock absorber unit 600 is formed of a pneumatic or hydraulic cylinder inside the first and second bearings 410 and 510.

Here, the cylinder means the internal space of the first support 410 or the second support 510, specifically, a cushioning material 516 is provided in the cylinder, and a piston is connected to the inside of the cylinder, Thereby buffering the impact load generated between the cable 100 and the bottom surface.

That is, since the structure of the net cable 100 supports the vertical external force by the tensile force in the horizontal direction, a large variation occurs in the external force in the relatively vertical direction. Accordingly, the structure of the net cable 100 provided with the solar panel is generated by the wind pressure.

At this time, the net cable 100 having the upward displacement is restored, and a shock occurs to the floor of the building. This impact load not only damages the solar panel P but also generates noise. Accordingly, the support pedestal 300 as described above has an effect of preventing an impact load on a vertical directional variation.

Hereinafter, a construction process of the solar panel support system according to the present invention will be described.

FIG. 5 is an exemplary view showing a state in which a net cable constituting a cable supporting system of a solar panel according to the present invention is installed, FIG. 6 is a view showing a net cable constituting a cable supporting system of a solar panel according to the present invention, Fig.

7 is a view illustrating an installation of the first and second bases constituting the cable supporting system of the solar panel according to the present invention. FIG. 2 is an exemplary view showing a state in which a support clamp is installed. FIG.

First, the cable support system of the solar panel according to the present invention can be installed on the upper surface of various types of buildings. Hereinafter, the case where the cable supporting system of the solar panel is installed on the slab S having a horizontal top surface will be described.

As shown in FIG. 5, the net cable 100 is installed on the upper surface of the slab S in a lattice form. That is, it is preferable that a plurality of net cables 100 are installed in a crossed state.

At this time, the connector 140 formed at the end of the net cable 100 is positioned on the side of the building.

Next, as shown in FIG. 6, the connector 140 is connected to install the master cable 200. That is, the master cable 200 connects the plurality of connectors 140 through the connector 140.

Here, first tension is applied to the net cable 100 by first tensioning the host cable 200. Therefore, the net cable 100 is maintained in a constant shape by the primary tensile force.

Next, as shown in FIG. 7, the first and second bases 400 and 500 are installed at intersections of the net cable 100. The first and second bases 400 and 500 are spaced apart from the bottom surface of the slab S by the net cable 100. More specifically, The net cable 100 is inserted. The slip prevention part 540 formed at the lower end of the second support 500 is stably installed on the ground.

Thereafter, the main hoist cable 200 is tensioned secondarily, and a secondary quan- tity of tension is applied to the net cable 100 in a designed amount.

The fixture 220 is fixed to an end of the mother ship cable 200 so that the secondary tensile force applied to the mother ship cable 200 is kept constant.

Of course, the secondary tension may further include a loss due to the fixture 220 being fixed.

Finally, as shown in FIG. 5, a support clamp 700 is installed on the first pedestal 400. Here, the support clamp 700 prevents the net cable 100 inserted into the insertion groove 444 of the first support 400 from coming off.

And, although not shown, a solar panel P is installed on the net cable 100. The method of joining the solar panel P and the net cable 100 may be combined by various methods of the prior art and will not be described in detail.

Meanwhile, the present invention can be embodied by combining a frame structure composed of rigid crawler or wood or the like and a cable structure.

A plurality of connecting cables 910 are connected to the rim of the fixed frame 900 along the rim.

One end of the connection cable 910 is fixed to the rim of the fixed frame 900, and the other end is disposed below the side surface of the building.

The connection cable 910 is provided with a through hole 920 at the other end and the main accessory cable 200 is connected to the through hole 920. The through-hole 920 has the same configuration as the connector 140 described above.

As a result, tensile force is generated on the connection cable 910 and the fixing frame 900 is fixed by the tensile force of the connection cable 910.

To this end, a fastener 220 for fastening an end portion of the main propulsion cable 200 to maintain the pulled state is provided at the end of the main accessory cable 200.

Fig. 10 shows another embodiment of a cable supporting system for a solar panel according to the present invention.
