And a support ball 60 for buffering the frame 50 and a support part 60 configured to accommodate the ball ball 100 and to buffer the corresponding ball ball 100, wherein the support part 60 is The reinforcing plate 70 is attached to the inner surface of the parapet (P) to the fixed by the adhesive 90 and the mesh net (80).

At this time, the frame 50 forms an outer groove 53 formed on the outer surface, and the support portion 60 is formed on the inner surface to accommodate the iron ball 100 corresponding to the outer groove 53 The support unit 60 is formed to form a 63, and the frame 50 forms a lower groove 55 formed at a lower surface thereof, and corresponds to the lower groove 55 to accommodate the iron ball 100. It includes the upper groove 65 formed on the upper surface.

As shown in FIG. 4, when an earthquake occurs in this state and vibration occurs, the iron ball inserted between the outer groove 53 of the frame 50 and the inner groove 63 of the support part 60 is brought into contact with each other. Due to the movement of the frame 50, the frame 50 may be moved in a rotational direction, and may be buffered. Due to the inserted steel ball 100, the frame 50 is moved in the longitudinal direction to enable a buffering action, so that the solar array T does not withstand vibration and is separated from the slab, falling to the ground, or falling to the roof of another building. By falling off, it can prevent the phenomenon which causes a secondary accident.

In addition, the adhesive 90 is an epoxy resin adhesive 90 is used as a waterproof, it is applied to a thickness of about 2.0 to 2.5mm.

After the epoxy resin adhesive 90 is applied, the mesh net 80 is attached so that the epoxy resin adhesive 90 is uniformly applied and fixed, and then the iron plate 70 is attached to the earthquake. Since the reinforcing plate 70 serves as a support for the parapet P to reinforce the buffering force against the parapet P, when the earthquake occurs even if a crack occurs in the parapet P, the parapet P is It can be prevented from being ruptured, causing debris to fall.

At this time, in order to more firmly attach the reinforcing plate 70, the screw 93 is put before the epoxy resin adhesive 90 is cured, by being inserted together with the less cured epoxy resin 90, When the screw 93 is put in place, the cracks are prevented from occurring, and the rainwater leaked between the cracks due to the construction causes the parapet P to penetrate into the internal cracks of the parapet P. In the freezing in winter there is an effect that can prevent the phenomenon of breaking the parapet (P).

In addition, the epoxy resin 90 is an intermediate of the thermosetting resin to form an insoluble / insoluble three-dimensional network structure by the reaction with the curing agent to exhibit the inherent physical properties of the epoxy, the epoxy resin 90 with the curing agent By the reaction, the adhesion, mechanical strength, heat resistance, chemical resistance, water resistance, electrical heat resistance, moldability, and impregnation are excellent, the composite material is easy to manufacture, and various physical properties can be realized according to the selection of the curing agent. There is an advantage.
