SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide a solar battery module fixing structure for a solar cell module which is convenient for construction by a simple detachable structure and conceals a bolt fastening part, Rail.

According to an aspect of the present invention, a channel-shaped insertion groove 21 is formed in the installation surface 11 including the roof panel 10 by a fixing screw 12, into which the fixing screw 12 is inserted , An inner rail (20) having a locking protrusion (22) formed inwardly on both sides of the upper end of the insertion groove (21);

A rail body 31 in the form of a cap for concealing the inner rail 20 in a state of being embedded therein and a rail body 31 formed integrally with the rail body 31, And an outer rail 30 including legs 33 formed at the lower end of the rail body 31 and extending to cover the mounting surface 11 A base rail for fixing a solar module is provided.

According to another aspect of the present invention, the locking protrusion 32 is provided with a head 35 inserted into the insertion groove 21 and a shaft 35 relatively smaller in diameter than the head 35, There is provided a base rail for fixing a solar module, wherein a bolt groove (34) formed of a shaft portion (36) extending outward is formed.

According to another aspect of the present invention, there is provided a base rail for securing a solar module, wherein a gasket (40) closely attached to the mounting surface (11) is detachably coupled to the leg (33).

As described above, according to the present invention, the inner rail 20, into which the fixing screw 12 is inserted and coupled, and the outer rail 30, which is adapted to house the inner rail 20, The inner rail 20 is installed at the outer side of the mounting surface 11 such as the upper rail 10 and the outer rail 30 is fitted to the inner rail 20, .

The present invention is also characterized in that the fixing screw 12 is hidden by the outer rail 30 while being inserted into the inner rail 20, There is no fear that rainwater or the like will be introduced, and the waterproof function can be sufficiently exhibited.

The bolt groove 34 is formed in the locking protrusion 32 so that the fixing bolt 13 and the like can be easily fastened to the bolt groove 34 when the panel- So that the convenience of installation can be provided.

The present invention is characterized in that a leg 33 extending to cover the mounting surface 11 is formed on the lower end side of the outer rail 30 and a gasket 40 The rainwater or the like can be prevented from flowing from the outside of the outer rail 30 to the fastening position where the fixing screw 12 is installed, thereby further increasing the waterproof effect.

1 is a cross-sectional view of a conventional example
2 is a cross-sectional view showing one embodiment of the present invention

The objects, features and advantages of the present invention will become more apparent from the following detailed description. Hereinafter, description will be made with reference to the accompanying drawings.

2 shows a preferred embodiment of the present invention. 2 and 3, the base rail of the present invention includes an inner rail 20 extended by a predetermined length so as to be installed on a mounting surface 11 such as a roof panel 10 by a fixing screw 12, And an outer rail 30 fitted into the inner rail 20 so as to house the inner rail 20. The inner rail 20 has a substantially U-shaped cross-section, and the fixing screw 12 is inserted An insertion groove 21 to be fastened to the bottom surface of the insertion groove 21 is formed.

The outer rail 30 is formed with a rail body 31 having a cap shape so as to house the inner rail 20. The rail body 31 is fitted into the insertion groove 21 on the upper surface side And the leg 33 is formed on both sides of the lower end and extends by a predetermined length.

In this configuration, the latching protrusion 32 is formed with a head which is reduced in diameter so as to be caught by the latching protrusion 22, and presses the latching protrusion 32 in the vertical direction on the inner rail 20, The head portion 35 inserted into the insertion groove 21 and the head portion 35 are relatively inserted into the engagement protrusion 32 so that they can be engaged with each other in the longitudinal direction. And a shaft portion 36 which is diametrically reduced in diameter and extends to the outside of the insertion groove 21 is formed.

The bolt grooves 34 are formed to correspond to the shape of a normal bolt. The bolt grooves 34 are formed by fixing the panel-type solar module P directly or fixing the separate fixed frame for fixing the solar module P For fastening the fixing bolts (13).

Legs 33 are formed on both sides of the lower end of the rail body 31 so as to cover the mounting surface 11. The legs 33 are inclined or horizontally corresponding to the shape of the mounting surface 11, And is provided to prevent rainwater or the like from flowing into the through hole 14 formed on the mounting surface 11 of the roof panel 10 or the like so as to fasten the fixing screw 12. [
