Abstract
The adjustable fast-assembling stair of a kind of width of the present utility model, comprise stair fixed end, stair sliding end, stair Connection Block, bolt assembly, industry wheel, bearing pin, stair mounting platform, scaffold floor, fixed end broadstep, sliding end broadstep, it is characterized in that: industry wheel is arranged on the two ends up and down of stair sliding end by bearing pin, industry wheel on stair sliding end is arranged on the chute of stair fixed end, lower end at stair Connection Block has long lumbar hole, by screw assembly, respectively at fixed end broadstep, be connected with sliding end broadstep, the upper end of stair is fixed in the installing hole of stair connecting platform, lower end is placed on scaffold floor.Novel structure is unique, advantages of simple, easy installation and removal, saving of labor, save time, material-saving, efficient, result of use is good, is the innovation on climbing frame support body stair device.
Description
Technical field
The utility model is applicable to not affect workman's construction and the current adjustable fast-assembling stair of a kind of width between the inner levels structure of integral lifting scaffold.
Background technology
Along with the high speed development of building trade, high-rise, super highrise building gets more and more, and extensively adopts integral lifting scaffold in construction, is called for short climbing frame.Outer protection and construction operation platform as building periphery.At support body inner bay, there is multilayer operating platform, between every layer operation platform, use stair to connect.In existing climbing frame, the width of stair is substantially consistent with the width of support body, width can not arbitrarily regulate, as met, set up stair place, to workman's construction operation and current bringing inconvenience, workman need to stand in herein scaffold floor edge when constructing operation and need to hold up support body just can construct, need to lean to one side and hold up support body could pass through (insert space is narrow, by difficulty) by herein time, cause so great potential safety hazard.
Utility model content
In order to overcome the defect of original technology, the object of the utility model be just to provide a kind of reliable, simplify, practical adjustable fast-assembling stair of width.When workman uses stair upper and lower as need, just only stair sliding end outwards need to be stretched and can pass through with adjustment width, as need be, in stair place constructing operation, carried out herein constructing operation after only the inside contracted width of stair sliding end need to being increased.Effectively solve the current time space of climbing frame access stairs place's constructing operation and people-to-people contacts narrow, the problem that potential safety hazard is larger, and simple in structure, be easy to install, easy to operate, save human cost.
The adjustable fast-assembling stair of width of the present utility model, comprise stair fixed end, stair sliding end, stair Connection Block, bolt assembly, industry wheel, bearing pin, stair mounting platform, scaffold floor, fixed end broadstep, sliding end broadstep, it is characterized in that: industry wheel is arranged on the two ends up and down of stair sliding end by bearing pin, industry wheel on stair sliding end is arranged on the chute of stair fixed end, lower end at stair Connection Block has long lumbar hole, by screw assembly, respectively at fixed end broadstep, be connected with sliding end broadstep, the upper end of stair is fixed in the installing hole of stair connecting platform, lower end is placed on scaffold floor.
The utility model novel structure is unique, advantages of simple, easy installation and removal, saving of labor, save time, material-saving, efficient, result of use is good, is the innovation on climbing frame support body access stairs device.
Accompanying drawing explanation
Fig. 1 is the front view of stair assembling of the present utility model.
Fig. 2 is that the axle shrinking in stair practical application of the present utility model is surveyed view.
Fig. 3 is that the axle of opening in stair practical application of the present utility model is surveyed view.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 3, provided, the utility model comprises stair fixed end 1, stair sliding end 2, stair Connection Block 3, bolt assembly 4, industry wheel 5, bearing pin 6, stair mounting platform 7, scaffold floor 8, fixed end broadstep 9, sliding end broadstep 10, it is characterized in that: industry wheel 5 is arranged on the two ends up and down of stair sliding end 2 by bearing pin 6, industry wheel 5 on stair sliding end 2 is arranged on the chute of stair fixed end 1, lower end at stair Connection Block 3 has long lumbar hole, by screw assembly 4, respectively at fixed end broadstep 9, be connected with sliding end broadstep 10, the upper end of stair is fixed in the installing hole of stair connecting platform 7, lower end is placed on scaffold floor 8.
Described stair sliding end 2 can freely horizontally slip by the chute on stair fixed end 1.
One end of described stair fixed end 1 is welded with stroke limit piece.
Described stair length can regulate according to actual needs.
The adjustable fast-assembling stair of the utility model width, can repeatedly dismantle, have enough to meet the need, reuse, and have saved artificial and material.When workman uses stair upper and lower as need, just only stair sliding end outwards need to be stretched and can pass through with adjustment width, as need be, in stair place constructing operation, carried out herein constructing operation after only the inside contracted width of stair sliding end need to being increased.Effectively solve the current time space of climbing frame access stairs place's constructing operation and people-to-people contacts narrow, the problem that potential safety hazard is larger, and simple in structure, be easy to install, easy to operate, save human cost.
