The scaffold board 15 cannot move in the horizontal direction under the action of the clamping groove 18 and the upright rod;
the scaffold board 15 is tightly attached to the horizontal rod by its own gravity in the longitudinal direction;
simultaneously, under the gravity of the scaffold board 15, operators, working tools and the like, the locking blocks 30 are pressed to move downwards, vertical gravity is decomposed under the conduction of the inner-row vertical rods 19, pressure is generated in the horizontal direction, the two locking blocks 30 are far away from each other, and the two scaffold boards 15 are pressed to be respectively abutted with the outer-row vertical rods 14 and the inner-row vertical rods 19; and the friction force of the contact surface of the locking block 30 and the limit groove 26 is increased under the influence of pressure, so that the scaffold board 15 is not easy to move in the horizontal direction.
In particular, when the scaffold board 15 is detached, only the lower worker only needs to use the steel pipe to jack up the scaffold board 15 on one side (the friction force between the locking block 30 and the limiting groove 26 is overcome, no worker is required to be arranged on the scaffold board 15, the limiting groove 26 is not extruded when the upward acting force is applied), when the scaffold board 15 exceeds the scaffold board 15 on the other side, the steel pipe is inclined to enable the scaffold board 15 to move towards the direction of the expansion joint, and then the detachment of the scaffold board 15 is completed, and after the scaffold boards on the same operation layer are detached, the locking mechanisms are detached one by one.
In addition, the expansion joints ensure that the scaffold plates 15 can remain stable and do not deform the uprights in a high temperature operating environment.
In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The foregoing is merely illustrative of the structures of this invention and various modifications, additions and substitutions for those skilled in the art can be made to the described embodiments without departing from the scope of the invention or from the scope of the invention as defined in the accompanying claims.
