The seismic device 5 of the present invention may be used to connect any two structures as shown in FIG. 2A in the first to third structures of the photovoltaic power generation facility, or to connect three structures as shown in FIG. 2B.
As described above, the structure connected to the upper part of the seismic device according to the position of the seismic device 5 based on the present invention, is connected to the upper structure, the lower part of the seismic device (5) A structure can be defined as a substructure.
In addition, the foundation, which is the first structure, may mean the installation of the chemical anchor 11 on the slab such as the roof of a building, or may refer to the concrete foundation 1 including the anchor 11 in the ground. It may also mean a bolt that drills a bolt hole in the structure and is fastened thereto.
Before describing the seismic device 5 according to the second embodiment, it will be described with reference to the seismic device 5 installed between the first structure and the third structure for convenience of description.
As shown in the figure, the seismic device 5 of the present invention forms a coupling plate 52 for bolting to a structure to be connected to a circumference, and a plurality of bodies protruding to one side to have a space therein correspond to each other. It constitutes the lower body 53, 55. The lower body 55 is in the form of a cap, the upper body 53 is a form in which the lower body 55 is upside down.
The shock absorbing member 6 is installed in the inner surface 54 of the space 53 of the upper body 53 or the lower body 55 of this type. In addition, the buffer member 6 may be installed on each of the upper and lower body 53 and 55 space inner surfaces 54.
The upper and lower bodies 53 and 55 pass through a contact portion, and fit the coupling bolts 54 into the through holes 58 and fasten nuts 56 to each other. At this time, the head of the coupling bolt 54 supports the buffer member 6 to be coupled to compress the buffer member 6 by tightening the coupling bolt 54 and the nut 56. The shock absorbing member 6 may be configured as a coil spring 60, or may be configured as a curved leaf spring 61 or a synthetic resin or rubber sheet having elasticity.
On the other hand, rather than compressively supporting the cushioning member 6 through the head of the coupling bolt 54, as shown in Figure 4b, the support panel formed with a bolt hole between the head of the coupling bolt 54 and the buffer member ( By installing 70, the support panel 70 may be configured to compress the shock absorbing member 6 by tightening the coupling bolt 54. In addition, a secondary buffer member 65 is provided between the lower portion of the support panel 70, that is, the upper surface of the base 1 and the support panel 70.
The secondary buffer member 65 may perform another function in addition to simply filling the lower space of the support panel 70. That is, when the secondary shock absorbing member 65 is installed in a compressed state, it has an effect of delaying the elastic recovery speed of the shock absorbing member 6 installed on the upper portion of the support panel 70.
When the secondary cushioning member 65 is compressed and filled in this manner, the compressive force acts to elevate the support panel 70 at normal times. When the earthquake occurs in this state and shakes the foundation 1, the seismic device 5 firmly coupled thereto is shaken. By this operation, the pillar 2 installed on the seismic device 5 is also shaken, and only the lower portion of the pillar 2 is moved by the weight and inertia of the frame and the solar panel 3 installed at the lower portion of the pillar 2. . That is, if the earthquake-resistant device 5 moved to the left side together with the foundation 1 by an earthquake, the lower part of the pillar 2 coupled thereon moves to the left side, but the upper part is going to be left as it is to the right side. It will tilt.
By this operation, the support bolt 70 is pulled while the fastening bolt 55 on the left side is pulled, and the shock absorbing member 6 in the pulled position is compressed. The vibration energy due to the earthquake is absorbed by the compression of the shock absorbing member 6, and the same phenomenon occurs in different directions when the vibration cycle of the earthquake is changed. However, when the compressive force of the shock absorbing member 6 is solved, the fast restoring force is acted on by the elastic force of the shock absorbing member 6, which may have a negative effect on the safety of the structure.
The secondary shock absorbing member 60 is filled with the shock absorbing member 6 as it expands into a space formed at the bottom thereof and simultaneously pushes up the support panel 70.
When the cushioning member 6, which has been compressed to the opposite side, elastically recovers, the secondary cushioning member 60, which is filled while expanding into the space, is compressed again, so that the elastic returning speed is inevitably delayed. The phenomenon in which the inclined pillar 2 is quickly returned by this phenomenon and adversely affects the structure is effectively prevented. On the other hand, it is also possible to reinforce the coil spring in an even distribution inside the secondary buffer member (60).
And the buffer member 6 of the coil spring (60) and the leaf spring (61) deriving an appropriate value through structural calculation and experiment to the extent that the degree of compression does not impair the stability of the structure as a whole, and tightened only by that value do. This value should be applied to each structure. In addition, as the shock absorbing member 6, in addition to the springs mentioned above, various kinds of suction means such as elastic rubber plates may be used.
For the convenience of explanation, the installation structure of the seismic device 5 having such a structure will be described, for example, provided between the first structure (base 1) and the pillar 2, which is the second structure.
Position the lower body 51b of the seismic device 5 on the foundation 1 (lower structure), and anchor the bolt 11 formed on the upper surface of the foundation 1 with the bolt hole formed in the coupling plate 52 of the circumference. Insert and tighten the nut on top to tighten it. And match the bolt hole while corresponding to the base plate 20 of the column (2) (upper structure) to the coupling plate 52 of the upper body 53, then insert the bolt and tighten the nut to firmly combine.
In this state, when an earthquake occurs and lateral shaking occurs, the pillar 2 supporting the heavy material such as the solar panel 3 and the frame 30 on the upper side is moved back and forth or left and right by the inertia of the upper weight. I'm shaking. At this time, the pillar 2 is slightly inclined vertically. Of course, when the vibration width due to the earthquake becomes larger, the inclination angle of the pillar 2 becomes larger.
Meanwhile, one side of the upper body 53 bolted to the base plate 20 of the lower part of the column 2 is lifted upward, and the shock absorbing member 6 elastically installed on the inner surface of the upper body 51a or lower body 51b space. ) Is further compressed by the coupling bolt 54 or the support panel 70. When the direction of vibration is changed, the position of the buffer member 6 to be compressed is also changed. By this operation, a considerable amount of seismic vibration energy is absorbed and the phenomenon of damaging the solar panel 3 installed at the top can be prevented as much as possible.
Meanwhile, the upper surface of the lower body 50 is formed as a protruding curved surface 550, and the lower surface of the upper body 51a is formed as a concave curved surface 530, thereby causing fluctuations due to seismic vibration waves. When the upper and lower body (51a) (51b) was able to respond to the vibration more flexibly.
In addition, the protrusions 531 and the grooves 551 are formed on the curved surfaces 530 and 550 of the upper and lower bodies 51a and 51b to correspond to each other, and they are configured to be engaged with each other, and the inside of the grooves 551 are formed. The protrusion 531 inserted into the protrusion 531 is configured to be broken while the vibration is transmitted when a vibration of more than a critical limit (vibration of the solar panel is deformed) is transferred to the seismic device 5 by a relatively weak external force such as a strong wind. It is configured to prevent movement.
Hereinafter, the operation of the seismic device in the solar panel 3 installation structure according to the present invention will be described.
As the earthquake occurs in the ground and the vibration wave of the earthquake is transmitted to the column 2 through the foundation 1, the vibration is first transmitted to the lower body 51b, and the lower body 51b is together with the foundation 1. It starts to swing left / right / before / after.
The swing of the lower body 51b is to be sheared as it is to the upper body 51a, but the shock absorbing member 6 provided by the bolt 54 and the nut 56 absorbs and absorbs the vibration to the upper body 53. The transmitted vibration is minimized.
That is, each time the contact portion of the upper and lower body (51a) (51b) is opened by swinging and reattach, the coil spring (60) or the leaf spring (61) of the shock absorbing member (6) absorbs vibrations. By offsetting, vibration of the seismic waves transmitted to the solar panel 3 is minimized, thereby preventing the deformation and breakage of the solar panel 3.
8A and 8B are exemplary views showing the structure of an earthquake-resistant device according to the third embodiment of the present invention, as shown in the drawing, a rubber plate 62 (synthetic resin or synthetic rubber having elasticity) in which the shock absorbing member 6 is elastic. And a plurality of insertion holes 63 are formed vertically therein, and compression springs 64 are installed vertically in the insertion holes 63.
The seismic device having such a structure allows the rubber plate 62 to absorb the vibration when the vibration is weak, and to cushion the vibration more effectively by the compression spring 64 when the vibration is large, thereby generating the vibration in a horizontal direction. The vibration is absorbed and buffered. The compression spring 64 can be used for a long time by serving as a function of compensating for the characteristics of the rubber which is relatively easily deformed.
9A and 9B are exemplary views illustrating the structure of the seismic device according to the fourth exemplary embodiment of the present invention. As shown in the drawing, a plurality of insertion holes 63 are formed in the rubber plate 62, but are horizontally long. The compression spring 64 is horizontally installed in the insertion hole 63.
Arrangement of the insertion hole 63 may be arranged in a square, as shown in the drawing or circular or alternately installed.
The seismic device in the solar panel mounting structure of the present invention can effectively and economically respond to earthquake generation without largely replacing the existing solar panel mounting structure, and thus the demand will increase.
