Abstract
The utility model discloses a kind of steel external staircase, and it comprises stair built-in fitting, multiple steel ladder ladder beam, multiple stair bench, two steel columns and multiple pedal beam; The bottom being positioned at the stair bench of the bottom is connected with stair built-in fitting; Two spaced and parallel settings of steel column, and the metope interval of two steel columns and building is arranged; Steel ladder ladder beam one end is welded on metope or the pillar of building, and its other end is connected to steel column; Multiple stair bench is arranged between two adjacent steel ladder ladder beams, and one end of stair bench is welded on metope or the pillar of building, and its other end is connected to steel column; Multiple pedal beam is stepped to be located in multiple stair bench respectively, and adjacent two pedal beams are equipped with checkered steel plate.The utility model structure is simple, and it adopts steel steel ladder ladder beam to be connected with the pillar of the metope originally built or existing building, reduces steel column quantity, thus reduces steel using amount, and then reduce the set-up time.
Description
Technical field
The utility model relates to building structure field, particularly relates to a kind of steel external staircase.
Background technology
What the staircase structure of current domestic house mainly adopted is traditional reinforced concrete cast-in-situ stair and common steel external staircase two type.Traditional reinforced concrete stairs needs molding cast-in-site at the scene, and concrete operation is many, and curing time is long, is unfavorable for that industrialization large-scale production is installed.
Steel external staircase is the product of industrial age, in the past in industrial building extensive use.Common steel external staircase has many good qualities compared with concrete staircase, but also come with some shortcomings in current design and construction, main problem is as follows: 1, ordinary steel external staircase generally adopts stair girder steel and step plate separate machined, be welded into entirety at the scene, so not only in-site installation is cumbersome but also stair globality is poor; 2, common steel external staircase many employings welding manner is connected with agent structure, and the degree of on-the-spot quick-assembling is poor; 3, normal steel structure installation contrast locating is poor, does not relate to the erection bolt hole of constructability; 4, the vibrations of ordinary steel external staircase are larger, and when house uses, comfortableness is poor; If 5, ordinary steel external staircase needs increase stair globality during secondary pouring concrete, not consider relative configurations measure in relating on marking time, casting quality is difficult to ensure.In addition, existing steel external staircase cost is high, installs elapsed time long, requires high to construction environment.
Therefore for the problems referred to above, be necessary that a new steel external staircase of design is to make up above-mentioned defect.
Utility model content
For addressing the aforementioned drawbacks, the utility model proposes a kind of steel external staircase, its structure is simple, and easy for installation, the set-up time is short, and steel using amount is low, and cost is low.
The technical solution of the utility model is achieved in that
A kind of steel external staircase, it comprises stair built-in fitting, multiple steel ladder ladder beam, multiple stair bench, two steel columns and multiple pedal beam; The bottom being positioned at the stair bench of the bottom is connected with stair built-in fitting; Two spaced and parallel settings of steel column, and the metope interval of two steel columns and building is arranged; Steel ladder ladder beam one end is welded on metope or the pillar of building, and its other end is connected to steel column; Multiple stair bench is arranged between two adjacent steel ladder ladder beams, and one end of stair bench is welded on metope or the pillar of building, and its other end is connected to steel column; Multiple pedal beam is stepped to be located in multiple stair bench respectively, and adjacent two pedal beams are equipped with checkered steel plate.
Wherein, steel external staircase is provided with stair connecting piece further, and stair bench is connected by stair connecting piece with stair built-in fitting.
Wherein, form the first angle between two adjacent stair bench, and the first angle is acute angle.
Wherein, the two ends of checkered steel plate are welded on two adjacent pedal beams respectively.
Wherein, stair bench is provided with handrail and railing.
Compared with prior art, the utility model tool has the following advantages: the utility model steel ladder ladder beam is connected with the pillar of the metope originally built or existing building, reduces steel column quantity, thus reduces steel using amount, and then reduce the set-up time.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of this practical steel external staircase;
Fig. 2 is the enlarged diagram of part A in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1 and Fig. 2, a kind of steel external staircase, it comprises stair built-in fitting (not shown), multiple steel ladder ladder beam 1, multiple stair bench 2, two steel columns 3 and multiple pedal beam 4; The bottom being positioned at the stair bench of the bottom is connected with stair built-in fitting; Two spaced and parallel settings of steel column, and the metope interval of two steel columns and building is arranged; Steel ladder ladder beam one end is welded on metope or the pillar of building, and its other end is connected to steel column; Multiple stair bench is arranged between two adjacent steel ladder ladder beams, and one end of stair bench is welded on metope or the pillar of building, and its other end is connected to steel column 3; Multiple pedal beam 4 is stepped to be located in multiple stair bench 2 respectively, and adjacent two pedal beams 4 are equipped with checkered steel plate 5.The utility model stair bench adopts hot rolled steel plate to be welded at entire plant.The quantity of the utility model stair bench designs according to floor, and the quantity of stair bench according to the actual requirements, can be kept identical with floor quantity, also can be designed to other quantity by those skilled in the art.
Metope or the pillar of the utility model steel ladder ladder beam one end and building are connected, can reduce steel column quantity, thus minimizing steel using amount, and then the minimizing set-up time, therefore the utility model steel external staircase only need use 2 steel columns.
Wherein, steel external staircase is provided with stair connecting piece (not shown) further, and stair bench is connected by stair connecting piece with stair built-in fitting.The utility model stair connecting piece adopts hot-rolled angle steel, and those skilled in the art according to the actual requirements can other stair connecting piece of choice for use, only need reach the object be connected with stair bench by stair built-in fitting.
Wherein, form the first angle between two adjacent stair bench, and the first angle is acute angle.The quantity of the utility model steel ladder ladder beam is arranged in conjunction with actual demand by those skilled in the art.
