Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 3, this embodiment provides a right angle connection structure of prefabricated house, including first wallboard 11 and second wallboard 12 of perpendicular concatenation formation corner, the inboard of first wallboard 11 and second wallboard 12 is equipped with

breach

111, 121 respectively in concatenation department along its respective length direction, forms a strip recess 13 between two

breach

111, 121, first wallboard 11 and second wallboard 12 offer tongue-and-

groove

112, 122 rather than parallel arrangement in the bottom of strip recess 13 respectively, the longitudinal section of tongue-and-

groove

112, 122 is the trapezoidal structure of wide bottom narrow of opening, the inside corner department of first wallboard 11 and second wallboard 12 is equipped with the retaining member through hand screw 3, the retaining member is including installing the right angle mounting panel 21 in corner department, the right angle mounting panel 21 outside is equipped with the connecting block 22 that extends to strip recess 13 department, the free end of connecting block 22 is equipped with two insertable tongue-and-groove 112, the free end of connecting
