At present, in an assembly type building, a wall body is of an assembly type structure, but a stair generally adopts a cast-in-place reinforced concrete stair or a prefabricated reinforced concrete stair, and although the cast-in-place reinforced concrete stair has great advantages in firmness, sound insulation effect and maintenance-free property, the reinforced concrete stair has great self weight, needs complex processes such as formwork support, reinforcement binding, cast-in-place and maintenance and the like, and has the defects of long construction period, more hidden projects, poor quality controllability and the like; the prefabricated reinforced concrete stair has the defects of heavy self weight, large-scale mechanical installation, complex on-site connection node and the like, and is limited in the popularization process.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides the profile steel lightweight concrete stair which is simple in structure, convenient to manufacture, light in weight, high in strength and capable of shortening the construction period.
In order to solve the technical problems, the invention adopts the following technical scheme: the section steel lightweight concrete stair comprises two section steel ladder beams which are arranged side by side and obliquely, wherein a plurality of angle steel steps are horizontally arranged between the two section steel ladder beams, two ends of each angle steel step are respectively welded with the two section steel ladder beams into a whole, each angle steel step comprises a vertical section and a horizontal section, and the front side edge of the horizontal section of each angle steel step is butted and welded with the lower side edge of the vertical section of the adjacent angle steel step into a whole;
the rear side of the horizontal section upper surface and the vertical section that the angle steel was marked time all are provided with anti-skidding protective layer, and anti-skidding protective layer is pour in the mill by lightweight concrete and is formed.
Still the level is provided with a plurality of support angle girder steel between two shaped steel ladder beams, supports angle girder steel both ends and welds as an organic wholely with two shaped steel ladder beams respectively.
The back side of the horizontal segment upper surface and the vertical segment that the angle steel was marked time all welds the blind pin, is provided with the enhancement net piece that is on a parallel with the angle steel and marks time on the blind pin, and enhancement net piece and blind pin are pre-buried inside by lightweight concrete.
The upper end and the lower end of the two section steel ladder beams are both provided with a steel structure platform, and the steel structure platform is provided with a small stool.
By adopting the technical scheme, compared with the prior art, the invention has the following advantages:
1. the shaped steel ladder beam adopts square pipe or channel-section steel, and the angle steel is marked time and is supported the angle steel all and adopt the angle steel, adopts to weld a plurality of shaped steel between two shaped steel ladder beams and mark time and adjacent two shaped steel and mark time also mutual welded structure, ensures fail safe nature, and convenient preparation has reduced a lot of work progress, has shortened construction cycle, has reduced construction cost.
2. In order to further improve the connection strength between the two section steel ladder beams and the safe support for the angle steel stepping, a plurality of supporting angle steel beams are welded between the two section steel ladder beams, and the safe reliability of the angle steel stepping is ensured.
3. The anti-skidding protective layer is arranged on the upper surface of the angle steel step, the studs and the reinforcing mesh sheets are embedded in the anti-skidding protective layer, so that the stability of the anti-skidding protective layer can be improved, the anti-skidding protective layer and the angle steel step to form a whole, and cracks cannot be generated.
4. Because old person's legs and feet are inconvenient, perhaps need have a rest in the stair in-process about going upstairs, consequently set up little stool in the corner department of steel construction platform for the old person sits down the rest when going upstairs and downstairs on the steel construction platform.
Drawings
Fig. 1 is a schematic side view of the present invention.
Detailed Description
As shown in fig. 1, the section steel lightweight concrete stair disclosed by the invention comprises two section steel ladder beams 1 which are arranged side by side and obliquely, wherein a plurality of angle steel steps 2 are horizontally arranged between the two section steel ladder beams 1, two ends of each angle steel step 2 are respectively welded with the two section steel ladder beams 1 into a whole, each angle steel step 2 comprises a vertical section and a horizontal section, and the front side edge of the horizontal section of each angle steel step 2 is butted with the lower side edge of the vertical section of the adjacent angle steel step 2 and welded into a whole;
the angle steel 2's horizontal segment upper surface and the trailing flank of vertical section all are provided with anti-skidding protective layer 4, and anti-skidding protective layer 4 is pour in the mill by lightweight concrete and is formed.
Still the level is provided with a plurality of support angle girder steel 3 between two shaped steel ladder beams 1, and 3 both ends of support angle girder steel weld as an organic whole with two shaped steel ladder beams 1 respectively.
The back side of the horizontal segment upper surface and the vertical segment of angle steel 2 of marking time all welds the blind pin, is provided with the enhancement net piece that is on a parallel with the angle steel 2 of marking time on the blind pin, and enhancement net piece and blind pin are pre-buried inside by lightweight concrete. The protective anti-slip layer 4 and its internal studs and reinforcing mesh are not shown in the figure.
The upper end and the lower end of the two section steel ladder beams 1 are both provided with steel structure platforms (not shown in the figure), and the steel structure platforms are provided with small stools.
Compared with the prior art, the invention has the following advantages:
