Mouth vertical rod, the left and right portion of two groups of long horizontal-associate formation staggered relatively standard knots connecting vertical rod supports, and takes two hyphens connection, hyphen
The vertical rod of two before and after two groups of long horizontal-associates staggered relatively is connected by the left and right sides of connection, supports before and after forming standard knot；
C, on the basis of cat ladder mounting seat；
D, pre-splicing good entrance joint is arranged on base；
E, pre-splicing good standard knot is arranged on entrance joint on；
F, installing at entrance joint and standard knot bottom and turn round platform, the most adjacent two to turn round platform be that relative direction is put
Put；
G, turn round between platform installation stair at the most adjacent two；
I, entrance joint with the internally installed anti-throwing net of standard knot.
J, on standard knot install attachment apparatus.
Embodiment 5
As shown in Figure 15,16,17, the basic phase of structure of the structure of the present embodiment safety climbing ladder and embodiment 4 safety climbing ladder
With, its difference is:
First, base 2 is formed in one with entrance vertical rod 6, and such frame mode makes stablizing of base and entrance vertical rod
Property is higher, and easily the vertical rod 7 of entrance vertical rod 6 with standard knot is distinguished, and easily distinguishes.
Secondly, being provided with pad between anti-throwing net 13 and the steel wire connecting hole of cat ladder main body, pad is by original point
Contact changes present face contact into, makes the anti-throwing net 13 stationarity in cat ladder main body more preferable, is difficult to get loose.
Finally, attachment apparatus 14 is made up of Anchored Bar 14-3, the first locking plate 14-1 and the second locking plate 14-2, the first locking plate 14-1
Having about two bolts hole arranged, middle part has bar shaped Anchored Bar slot, and the second locking plate 14-2 has two and locks with first
The bolt hole that sheet bolt hole size is identical, middle part has square Anchored Bar slot.First locking plate 14-1 is arranged on the second locking plate 14-
On 2, the bolt hole on two locking plates overlaps, and Anchored Bar 14-3 inserts in the slot on the first locking plate 14-1 and the second locking plate 14-2
It is attached fixing, by bolt, the first locking plate 14-1 and the second locking plate 14-2 is fixed on neighboring buildings surface, Anchored Bar
14-3 one end is connected with cat ladder main body, and the other end is fixed with locking plate.
Above in association with accompanying drawing, the preferred embodiment of the present invention is elaborated, but the present invention is not limited to above-mentioned reality
Execute mode, in the ken that skilled artisan is possessed, it is also possible to before without departing from present inventive concept
Put that various changes can be made.
