Description

A kind of steel structure stairway
Technical field
The utility model relates to field of steel structure for building, refers in particular to a kind of steel structure stairway.
Background technology
Stair are important component parts of building construction, and for different buildings, stair form that can be for you to choose, only has stringer type stairway, slab type stairway and concrete structure stair; Adopt concrete structure stair, its work progress is complicated, and technical economic benefit is low; While adopting stringer type stairway and slab type stairway, it is marked time is to be all directly welded on cant beam, tends to the injustice of marking time after making, greatly affects result of use and the security performance of stair.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, easy for installation, steel structure stairway that result of use is good is provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of steel structure stairway, the step that it includes rest ledge and is connected to rest ledge end; Described rest ledge bottom is two i iron that be arranged in parallel, and i iron bottom is fixed by fixed bar and set bolt; I iron welded top has rest ledge table top; Described step includes two girders of marking time that be arranged in parallel, and the girder of marking time tilts to be arranged between adjacent rest ledge or between rest ledge and ground or between ground and flooring; Article two, mark time and between girder, be horizontally installed with uniform the marking time of some joints; The described two ends of marking time are the downward channel-section steel of sidewall, the welded top of the channel-section steel panel of marking time, the inner side of channel-section steel outer wall is vertically fixed with by bolt the column of marking time, and the column lower end of marking time is provided with adjustment hole, and the column of marking time is arranged on channel-section steel girder by this adjustment hole and the bolt of marking time.
The utility model has the advantage of: all parts all can be directly in factory's volume production, time saving and energy saving; During installation, directly adopt bolt to fix, easy for installation, and can to the plane of marking time, regulate by adjustment hole while installing, after guaranteeing to install, mark time smooth.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is tread structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, and preferred embodiment of the present utility model is: referring to accompanying drawing 1 and accompanying drawing 2, and the step 2 that the steel structure stairway described in the present embodiment includes rest ledge 1 and is connected to rest ledge 1 end; Described rest ledge 1 bottom is two i iron that be arranged in parallel 3, and i iron 3 bottoms are fixing by fixed bar 4 and set bolt 5; I iron 3 welded top have rest ledge table top 6; Described step 2 includes two girders 7 of marking time that be arranged in parallel, and the girder 7 of marking time tilts to be arranged between adjacent rest ledge 1 or between rest ledge 1 and ground or between ground and flooring; Article two, mark time between girder 7, be horizontally installed with some joints uniform mark time 8; Described 8 two ends of marking time are the downward channel-section steel of sidewall 9, the welded top of channel-section steel 9 panel 10 of marking time, the inner side of channel-section steel 9 outer walls is vertically fixed with by bolt the column 11 of marking time, column 11 lower ends of marking time are provided with adjustment hole 12, and the column 11 of marking time is arranged on channel-section steel girder 7 by this adjustment hole 12 and the bolt 13 of marking time.All parts of this programme stair all can be directly in factory's volume production, time saving and energy saving; During installation, directly adopt bolt to fix, easy for installation, and can to the plane of marking time, regulate by adjustment hole while installing, after guaranteeing to install, mark time smooth.
The embodiment of the above is only the preferred embodiment of the utility model, not with this, limits practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
