Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Bracing members anti-drop device as shown in Fig. 17, pre-including be fixed on diaphram wall 1
Bury steel plate 2, between two pieces of relative pre-embedded steel slabs 2, support is had bracing members 3, described pre-embedded steel slab 2
Bottom is fixed with Support bracket 4, and the bottom of described bracing members 3 is arranged on Support bracket 4；Described pre-
Bury the wire rope bracket 5 that steel plate 2 is arranged over being fixed on diaphram wall 1, one end of steel wire rope 6
Being fixed on wire rope bracket 5, the other end is fixed on the front end of bracing members 3.By Support bracket 4
Increase the structural strength bottom bracing members 3, increased the stability of bracing members 3 end by steel wire rope 6,
Guarantee bracing members 3 difficult drop-off, simple in construction, easy for installation.
In technique scheme, Support bracket 4 includes the first support being fixed on bottom pre-embedded steel slab 2
Plate 4.1, the top of the first gripper shoe 4.1 is fixedly connected with the second perpendicular gripper shoe 4.2.First
It is fixedly connected with polylith between gripper shoe 4.1 and the second gripper shoe 4.2 and strengthens gripper shoe 4.3, strengthen propping up
The side surface of fagging 4.3 and the laminating of the first gripper shoe 4.1 are fixing, end face and the end of the second gripper shoe 4.2
