Description

A kind of temporary stairways
Technical field
The utility model relates to a kind of temporary stairways.
Background technology
The temporary stairways of construction site mainly adopts the fixed stair of shaped steel welding or assembly production.Although and adopt shaped steel to weld or the fixed stair globality of assembly production better, cost of manufacture is higher, and, only can be applicable to the construction level of sustained height, thus far can not meet industrial requirement.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of temporary stairways, and its structure is simple, makes simple and convenient, is conducive to reducing cost of manufacture, and, be also applicable to the construction level of differing heights, thus its scope of application can be expanded.
For solving the problem, the technical scheme that the utility model adopts is as follows:
A kind of temporary stairways, comprise spaced two bracing frames, along bracing frame length direction be arranged in order and several pedals be parallel to each other, with this two bracing frames one_to_one corresponding and in two bases be oppositely arranged; Support frame as described above comprises the first girder and the second girder that are parallel to each other; First girder of this two bracing frame in being oppositely arranged, and is parallel to each other; Second girder of this two bracing frame is in being oppositely arranged; Described pedal is between this two bracing frame; The left and right sides of the rear end of described pedal is hinged on the second girder of this two bracing frame respectively correspondingly, and the left and right sides of the front end of described pedal is hinged on the first girder of this two bracing frame respectively correspondingly; The end of the first girder of support frame as described above, the end of the second girder are hinged on the base corresponding with this bracing frame respectively.
This temporary stairways also comprises two balustrade assemblies of the pedal left and right sides that is placed in; Described balustrade assemblies comprises cross bar, is arranged in order and several hinged with cross bar respectively montants along bracing frame length direction; The bottom of described montant is fixed on pedal.
Described balustrade assemblies comprises two cross bars of arranging successively from top to bottom, described montant is provided with first connecting portion hinged with a wherein cross bar, second connecting portion hinged with another cross bar.
The upper surface of described pedal is formed as trampling face in horizontally disposed.
Described base is arranged on the lower end of bracing frame, and the upper end of the second girder of support frame as described above is formed as link.
Compared to existing technology, the beneficial effects of the utility model are:
Structure of the present utility model is simple, makes simple and convenient, is conducive to reducing cost of manufacture, and, be also applicable to the construction level of differing heights, thus its scope of application can be expanded; In addition, its globality is good, it is simple and convenient to install, and is conducive to promoting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state schematic diagram of the present utility model;
Wherein, 1, bracing frame; 11, the first girder; 12, the second girder; 2, pedal; 31, cross bar; 32, montant; 4, base.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Figure 1, 2, be a kind of temporary stairways of the present utility model, comprise spaced two bracing frames 1, along bracing frame 1 length direction be arranged in order and several pedals 2 be parallel to each other, with this two bracing frame 1 one_to_one corresponding in two bases 4 be oppositely arranged; Support frame as described above 1 comprises the first girder 11 and the second girder 12 be parallel to each other; First girder 11 of this two bracing frame 1 in being oppositely arranged, and is parallel to each other; Second girder 12 of this two bracing frame 1 is in being oppositely arranged; Described pedal 2 is between this two bracing frame 1; The left and right sides of the rear end of described pedal 2 is hinged on the second girder 12 of this two bracing frame 1 respectively correspondingly; The left and right sides of the front end of described pedal 2 is hinged on the first girder 11 of this two bracing frame 1 respectively correspondingly; The end of the first girder 11 of support frame as described above 1, the end of the second girder 12 are hinged on the base 4 corresponding with this bracing frame 1 respectively.
When reality uses, base 4 can be fixed on lower floor, and bracing frame 1 one end away from base 4 is fixed on upper strata, thus be convenient to constructor and move between upper strata and lower floor through this temporary stairways.The utility model is by simplifying structure, its structure can be made comparatively simple, make simple and convenient, be conducive to reducing cost of manufacture, and, because the end of the first girder 11 of bracing frame 1, the end of the second girder 12 are hinged on base 4 respectively, the first girder 11, second girder 12 can be rotated around base 4, thus be applicable to the construction level (such as H1 or the H2 height etc. of Fig. 2) of differing heights, to expand its scope of application.
Preferably, this temporary stairways also comprises two balustrade assemblies of pedal 2 left and right sides that is placed in; Described balustrade assemblies comprises cross bar 31, is arranged in order and several hinged with cross bar 31 respectively montants 32 along bracing frame 1 length direction; The bottom of described montant 32 is fixed on pedal 2.And by adopting the design of balustrade assemblies, the security performance of use can be improved.
Preferably, described balustrade assemblies comprises two cross bars 31 of arranging successively from top to bottom, described montant is provided with first connecting portion hinged with a wherein cross bar 31, second connecting portion hinged with another cross bar 31.
Preferably, the upper surface of described pedal 2 is formed as trampling face in horizontally disposed, tramples thereon for pedestrian.And due to by rationally arranging the first girder 11, second girder 12 and the annexation of pedal 2, when the first girder 11, second girder 12 respect thereto 4 rotates, make pedal 2 to keep level.
Wherein, described base 4 is arranged on the lower end of bracing frame 1, and the upper end of the second girder 12 of support frame as described above 1 is formed as link, is connected for the upper strata of construction level.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
