Description
Technical field
The utility model relate to a kind of be used to climb the differing heights building can semifixed folding stair, relate in particular to a kind of when not using, can draw in folding, thereby can effectively save the wall-hanging emergency staircase in space.
Background technology
No matter be industrial or civilian, when on the job platform of differing heights, carrying out work, often use that stair are climbed and conveying objects.
The stair of prior art have two kinds of forms: be completely fixed formula stair and complete movable stair.
One, being completely fixed the formula stair, is fixedly to form by the steel concrete cast or by welding such as steel plate, steel pipes; Promptly become the part of each job platform after this stair are installed, can not demolition and move, as residential building with the maintenance of stair and industrial big tank wall with stair etc.Its advantage is, and is durable.
The shortcoming that is completely fixed the formula stair is:
(1) owing to the passage of fixed stair as affiliated building, it is built with building or building builds up the special design-build in back; If with steel concrete cast, in manufacture process, concrete staircase need be taken template, ties up reinforcing bar, the mud of pouring water, and treating needs once more floating and swabbing after cement solidifies fully; Operation just can come into operation if steel structure stairway then needs to cut, transports, assembles, welds, surperficial mopping is anticorrosion etc.; Therefore it is longer to be set the cycle;
(2) because fixed stair itself are very heavy, be fixed on the job platform (floor), therefore increased the load of job platform (floor), but the supporting capacity in their work is reduced;
(3) because fixed stair itself are bulky, in case fixing, can't move and dismantle, therefore take a large amount of spaces, hinder the carrying out of other operation;
(4) in a single day install owing to fixed stair, the corridor width, the corner space size, stair inclination angle etc. all is completely fixed, and can't adjust, and some special article of carrying (super large, overweight) is restricted;
(5) fixed stair are in case damage is keeped in repair very loaded down with trivial details.
Two, complete movable stair, its structure is made up of main brace summer and gangboard, does not have handrail usually, constitutes light short and small simple and easy ladder.Its advantage is, can set up whenever and wherever possible and move, and can be according to actual conditions adjustment height and inclination angle, for example Chang Yong lifting fire ladder.
The shortcoming that complete movable stair are the plain type stair is:
(1) only forms owing to the plain type stair by main brace summer and foot pedal, there is not handrail, therefore main brace summer flexible deformation is bigger, make personnel up and down or carrying less stable during article, therefore up and down personnel can only hand steered main brace summer keeping stable, but still cause the generation of fallen accident easily;
(2) because plain type stair footing does not have the self-locking fastening devices, in use generation is slided and is caused and topple easily, therefore in use need one or several personnel to help to help keeping the stable of stair usually, thus waste labour and increased the inconvenience of using;
(3) because plain type stair supporting capacity is little, majority only is applicable to about the personnel, be unsuitable for carrying article, so function of use is little.
Summary of the invention
The purpose of this utility model is to provide a kind of improved wall-hanging emergency staircase, and it had when both having guaranteed to use about big supporting capacity and personnel's the safety, can behind complete operation these stair be reeled again, and is folding, is labelled to metope, thereby saves big quantity space.
