Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under paying creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
A kind of pin key connects the mounting structure of prefabricated bench, and its composition includes: bench 5, pin shaft hole 1, suspension hook 4, landing slab
9, ladder beam 3, described bench 5 is arranged between upper and lower two terraced beams 3, is provided with hole for hoist 2, in institute on the step of described bench 5
State bench 5 side and be provided with suspension hook 4 described in a group, the step of described bench 5 rear and front end respectively has pin shaft hole 1 described in a group；
Described ladder beam 3 is L-type, is built-in with pin key 16 at described ladder beam 3, and described pin shaft hole 1 is enclosed within described pin key 16, at described pin key
Described ladder beam 3 is fixed with described bench 5 by the vertical direction of 16 by reinforcement 23, pours CGM grouting in described pin shaft hole 1
Material 21.
The opening of described hole for hoist 2 is positioned at the step both sides of described bench 5, and described suspension hook 4 is located at described bench 5 side
Two ends.
Described pin key 16 is L-shaped, and in described pin key 16 lower end embedment described ladder beam 3, described pin key 16 upper end is inserted into institute
