Description
Technical field
The utility model relates to a kind of construction cat ladder, is specifically related to a kind of To Construction of Silo reusable edible quickly dismantled cat ladder.
Background technology
In underground construction To Construction of Silo, the normal construction cat ladder that adopts is upper and lower for personnel.And by the restriction such as space and execution conditions, construction cat ladder is generally made dress and installed all more random, lack of standardization, most of safety protective cage performs practically no function, and potential safety hazard is given prominence to.And dig along with under vertical shaft, mostly need to carry out welding to cat ladder and extend, this production method holding time is longer, produces and there is certain interference, cause work efficiency to reduce to construction.And when follow-up cat ladder is removed, most of cat ladder is all adopt electric welding or oxygen welding directly to slice off, cannot recycling, cause the waste of resource.
Summary of the invention
Technical problem to be solved in the utility model is to provide the To Construction of Silo cat ladder that a kind of fast demountable recycles, and can reduce costs input, increase work efficiency.And structure is simple, swift to operate, safe and reliable.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of underground chamber To Construction of Silo cat ladder of quickly dismantled reusable edible, it comprises riding club, multiple riding club is connected with cat ladder ladder beam, outside cat ladder ladder beam, level is installed and protects cage, the cat ladder of cat ladder ladder beam supports to be fixed on the borehole wall of vertical shaft by shaft wall anchor pole, level protects cage more piece, every horizontal protect cage by protecting cage hook, screw and nut be fixed on cat ladder ladder beam, protect cage vertical rod and protect cage with level in the vertical direction and be connected.
Described cat ladder is multiple prefabricated joints, often saves between prefabricated cat ladder and adopts connecting bolt to connect.
The lower end of cat ladder ladder beam is provided with temporary ladder.
The To Construction of Silo cat ladder of a kind of quickly dismantled reusable edible that the utility model provides, this cat ladder structure is simple, can carry out prefabricated in advance, protect cage and can fold and remove, effectively can save memory space outside hole.Access ladder construction is with low cost, is conducive to construction safety, cat ladder can recycled for multiple times after removing, increase operation rate, reduce construction cost.

Detailed description of the invention
See Fig. 1-7, a kind of To Construction of Silo cat ladder kind of quickly dismantled reusable edible it mainly comprise riding club, level protects cage, cat ladder ladder beam, screw, nut, shaft wall anchor pole, cat ladder supports, protect cage hook, protect cage vertical rod, cat ladder connecting bolt, temporary ladder, multiple riding club 1 is connected with cat ladder ladder beam 3, outside cat ladder ladder beam 3, level is installed and protects cage 2, the cat ladder of cat ladder ladder beam 3 supports 7 and fixes on the borehole wall of vertical shaft 10 by shaft wall anchor pole 6, level protects cage 2 more piece, every horizontal protects cage 2 by protecting cage hook 8, screw 4 and nut 5 are fixed on cat ladder ladder beam 3, protect cage vertical rod 9 to protect cage 2 in the vertical direction with level and be connected.
The To Construction of Silo cat ladder of the utility model quickly dismantled reusable edible can carry out prefabricated in advance outside hole, the length often saving cat ladder is no more than the height that vertical shaft excavates at every turn, be generally 2m ~ 2.5m, often save cat ladder to be welded and fixed with the shaft wall anchor pole of constructing in advance by cat ladder support, often save between prefabricated cat ladder and adopt connecting bolt 11 to connect
Connecting bolt and the attaching nut of the prefabricated cat ladder customization of adjacent two joint are connected and fixed, and connecting bolt can use as riding club.
Protect that cage vertical rod can level protects screw on cage by being welded in, nut is fixed.
For convenience of transport and save space, horizontal cage hoop can carry out folding and fixes by being welded in hook on screw on terraced beam and horizontal cage hoop.
Except riding club 1 welds with cat ladder ladder beam 3, outside cat ladder support 7 is welded with shaft wall anchor pole 6, remaining part all adopts screw 4 and nut 5 to be connected and fixed.Level protects cage 2, protect cage hook 8, protect cage vertical rod 9 all can remove.
The lower end of cat ladder ladder beam 3 is provided with temporary ladder 12, and temporary ladder 12 is connected with cat ladder ladder beam 3 by arc hook.
Be below an example of making of the present utility model: riding club 1 adopts Ф 25mm screw-thread steel, cat ladder ladder beam 3 adopts 60mm*10m band steel, cat ladder to support ∠ 50mm*6mm, all can weld in processing factory, welds screw 4 outside terraced beam 3.
Level is protected cage 2 and is adopted 50mm*4mm band steel to process by specification in processing factory, and welds screw.
Protect the arrangement pitch that cage vertical rod 9 protects cage in processing factory by level and open bolt hole.
Shaft wall performs shaft wall anchor pole 6 at the position need installing cat ladder, and borehole wall anchor pole position should support 7 corresponding with cat ladder.
Level is protected cage 2 to be fixed with the cat ladder nut 5 of welding forming in processing factory site.Protect cage hook 8 to be loaded on level and to protect on cage 2, be not temporarily connected with terraced beam 3.
The level of installing protected cage 2, protect the cat ladder of cage hook 8 and be transported to job site, cat ladder is supported and 7 to weld with the borehole wall anchor pole 6 of constructing in advance.Then be hung on protecting cage on screw that terraced beam has welded.Cage vertical rod nut will be protected be fixed on level and protect on cage.
For avoiding bursting work to damage mounted To Construction of Silo cat ladder, the shaft excavation scope of operation and the distance of having installed between cat ladder should at least keep 2.5m-3m(mono-to save the length of cat ladder), the distance between this adopts temporary ladder upper and lower for personnel.
Along with vertical shaft continuous under dig, when silo system supporting, cat ladder shaft wall anchor pole is constructed in the lump.Then cat ladder installation is carried out according to said procedure.Terraced beam between adjacent two joint cat ladders overlaps, and lap length is not less than 10cm.And perforate on terraced beam, perforate is not more than 28mm, and then adopt cat ladder connecting bolt 11 through the hole that terraced beam is opened, be finally fixed with 24# double nut, connecting bolt 11 is Ф 25 screw-thread steel of car silk.
After To Construction of Silo completes, merogenesis carries out dismounting cat ladder from bottom to top, and cat ladder supports 7 and adopts oxygen welding cutting with cat ladder shaft wall anchor pole.
