Claims

[Claims for Utility Model Registration] In the assembly type reinforced plastic grating, through holes 2 are provided at regular intervals on the side surface of the bearing bar 1, and the bearing bar 1 is inserted into the through holes 2.
A first cross bar 3 having a recess 3a of length X from the upper end to the through hole 2 is provided, and the first cross bar 3
is provided with a key groove 3b for fitting a part of the first cross bar 3 in the axial direction, and a second cross bar 4 that is slidably fitted into the through hole 2 of the bearing bar,
An assembly type reinforced plastic grating characterized by assembling the three types of members, the bearing bar, the first cross bar, and the second cross bar, using the required number of each. The first cross bar 3 is formed in a recess shaped so that it can be fitted into the upper part of the through hole 2 of the bearing bar 1, and the upper end surface of the first cross bar 3 is formed flush with the upper surface of the bearing bar 1. The assembled reinforced plastic grating according to claim 1, which is characterized in that: The cross-sectional shape of the bearing bar 1' is H-shaped, and the cross-sectional shape of the first cross bar 3' is T-shaped, and the horizontal part 3c of the first cross bar 3' is the horizontal part 1'a of the bearing bar. A grating made of prefabricated reinforced plastic according to claim 1 or 2, characterized in that a notch 3d having a width dimension Y is formed. The bearing bar 1'' has a T-shaped cross section, the first cross bar 3' has a T-shaped cross section, and the horizontal part 3c of the first cross bar 3' is the horizontal part 1'a of the bearing bar. A grating made of prefabricated reinforced plastic according to claim 1, claim 2, or claim 3, characterized in that a notch 3d having a width dimension Y is formed.
