When carrying out scaffold and assembling, the tip of horizontal pole connector and the tip fixed connection of horizontal pole insert the jack 52 of disc fastener with grafting portion 43 and the second cantilever of horizontal pole connector, also make the voussoir also be in predetermined mounted position simultaneously, realize preliminary location, and the spring is in the pre-compaction state this moment, and the spacing face 67 and the end connection 40 of first cantilever hold the bottom surface contact in chamber to the scarf 66 of second cantilever and the first inclined plane 33 contact of voussoir. Compared with the existing direct-insertion type disc fastener, the mode that the rod end connector is installed firstly and then the bolt is installed is adopted, the scaffold connecting assembly is characterized in that the wedge block is located in the wedge hole, so that the wedge block and the wedge hole form an integral structure, the pre-installation of the wedge block can be realized in the process that the end connector is inserted into the disc fastener, the installation efficiency is improved, the scaffold connecting assembly can be operated by one person, the existing direct-insertion type disc fastener needs two persons to be installed in a matched mode, the safety is improved, or the installation is carried out by one person, the cross rod needs to be held by one hand, and the bolt needs to be pulled by the other hand.
Participate in fig. 3, after the horizontal pole connector is connected with the disc fastener, downward external force is applied to the upper end of the wedge 3 in a hammering or mechanical pressurization mode, so that the wedge moves downwards along the wedge hole, the wedge is in the moving process, the first inclined plane 33 slides along the wedge surface and drives the second cantilever 64 to move towards the locking wall 53 side of the jack, when the locking surface 68 of the second cantilever 64 is abutted against the locking wall 53 of the jack, so that the disc fastener 5 is locked with the horizontal pole 2, and the horizontal pole 2 and the vertical pole 1 are in stable connection, thereby solving the problem of potential safety hazard.
When the cross bar and the upright post are disassembled, the upward thrust is applied to the lower end of the wedge block by adopting a hammering or mechanical pressurizing mode, so that the wedge block 3 moves upwards, so as to cancel the tension between the second cantilever and the insertion part, the wedge block 3 moves upwards to restore the spring, the crank arm is pivoted in the opposite direction by the spring force, the locking surface 68 of the second arm 64 is disengaged from the locking wall 53 of the receptacle, so that a space is formed between the first cantilever and the second cantilever, the second cantilever can exit from the jack of the disc fastener, the second cantilever is always in sliding contact with the first inclined plane of the wedge block in the rotating process, when the resisting surface at the lower end of the second cantilever is in mutual contact with the resisting platform of the wedge block, under the action of elasticity, the crank arm forms leverage to position the wedge block, so that the wedge block is prevented from falling under the action of gravity to lock the insertion part and the insertion hole again, and the scaffold connecting assembly and the disc fastener 5 are quickly detached; secondly, the blocking surface of the second cantilever forms vertical positioning for the wedge block, so that the wedge block is prevented from being separated from the cross rod connector in the dismounting process, and the problem that the bolt of the existing direct-insertion type disc buckle is easy to lose is solved; in addition, compared with the single-person dismounting mode of the existing direct-insertion type disc buckle, the cross rod needs to be held by one hand, and the bolt needs to be hammered by the other hand, as the scaffold is mounted and dismounted in high-altitude operation, safety accidents are easy to occur under the condition of two-hand operation, the dismounting efficiency is low, the bolt is easy to fall from high altitude under the action of gravity hammering, and potential safety hazards are caused to workers below the bolt.
Referring to fig. 10, in the repeated use process of the wedge block, the first inclined surface of the wedge block is worn to cause that an effective pushing force cannot be applied to the second cantilever, so that the wedge block needs to be replaced, when the wedge block is replaced, the crank arm is manually rotated and the spring is compressed until the wedge surface is in a vertical state, the blocking surface 65 and the blocking platform are dislocated in the horizontal direction, at the moment, the blocking surface 65 and the blocking platform are dislocated in the vertical direction, the wedge block is detached from the upper end of the wedge hole, separated from the cross rod connector, and a new wedge block is installed, and the replacement of the wedge block is completed.
The invention also protects a scaffold, which comprises upright posts 1, cross rods 2, disc fasteners 5 and a scaffold connecting assembly, wherein the disc fasteners 5 are fixedly sleeved on the upright posts 1, the end parts of the cross rods are connected with the scaffold connecting assembly, and when the scaffold is spliced, the scaffold connecting assembly inserting parts are inserted into the disc fasteners 5 and locked.
The above-mentioned contents are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and any modification made on the basis of the technical idea of the present invention falls within the protection scope of the claims of the present invention.
