Abstract
The utility model discloses a light-duty staircase tread crossbeam, including rectangular shape main part, the long limit of main part both sides inwards buckles perpendicularly respectively and forms first holding surface and second holding surface, the outside perpendicular bending of long limit of first holding surface outer end and extension form the installation face, the long limit of second holding surface outer end meets with the long limit of the hem outer end that a cross section is Z shape, the other two sides and the main part homonymy setting of hem. The structural design of the utility model can improve the strength of the pedal beam, so that the bearing strength of the step can be still ensured under the condition of using thinner materials, and the production cost is low; meanwhile, the pedal cross beam has low self weight, so that the power consumption during the running of the ladder way can be reduced, and the running cost is saved.
Description
Technical field
The utility model relates to a kind of light-duty staircase tread crossbeam.
Background technology
Existing assembled type stair step comprises one group of parallel spider and connection pedal assembly, kickplate assembly, main wheel axle bed, jockey pulley seat and jockey pulley thereon.In order to strengthen the loading strength of stair step, particularly strengthen bearing effect from the power of vertical directions such as pedal assembly, and the spider that is parallel to each other of restriction is subjected to displacement, usually below spider front end, pedal assembly, position installation crossbeams such as pedal assembly and inboard, kickplate assembly junction and spider rear end, kickplate assembly the place ahead.The beam body of this structure crossbeam is pressed into by sheet metal, and integral body is strip shape, connects with corresponding pedal assembly, kickplate assembly and two parallel spiders by the mode of being spirally connected.In order to guarantee staircase when operation, the step loading strength meets the safe operation standard and step is integrally-built stable, prevent that crossbeam from twisting bending because of undercapacity, the beam body is selected more thick and heavy sheet metal for use, therefore adopt the stair step weight of this structure crossbeam heavier, the productive costs height, electric energy is wasteful during the operation of terraced road, operating cost is high.
Summary of the invention
The utility model purpose provides a kind of light-duty staircase tread crossbeam, and its structure design can improve the intensity of pedal crossbeam, makes the loading strength that still can guarantee step under the condition of using thin material, and productive costs is low; Pedal crossbeam deadweight simultaneously is low, and the power consumption in the time of can reducing the operation of terraced road is saved operating cost.
The technical solution of the utility model is: a kind of light-duty staircase tread crossbeam, comprise the strip shape main body, the long limit of described main body both sides inwardly vertically is bent to form first bearing surface and second bearing surface respectively, the long limit of the described first bearing surface outer end outwards vertically bends and extends to form attachment face, the long limit of the described second bearing surface outer end and a cross-sectional plane are that the long limit of Z-shaped flanging outer end joins, and the other two sides of described flanging and main body homonymy are provided with.
The further technical scheme of the utility model is: a kind of light-duty staircase tread crossbeam, comprise the strip shape main body, the long limit of described main body both sides inwardly vertically is bent to form first bearing surface and second bearing surface respectively, the long limit of the described first bearing surface outer end outwards vertically bends and extends to form attachment face, the long limit of the described second bearing surface outer end and a cross-sectional plane are that the long limit of Z-shaped flanging outer end joins, and the other two sides of described flanging and main body homonymy are provided with; Described attachment face is provided with some mounting holes; The vertical two ends of described main body are provided with the installation portion towards plane, attachment face place depression, and described installation portion is provided with mounting hole.
The utility model advantage is:
1. the utility model adds Z-shaped flanging on crossbeam, and the effectively bend resistance of strengthened beam body, anti-twist intensity can the attenuate material thicknesses under the situation of same bearing force and can reach same moment of torsion, moment of flexure requirement, material saving, and productive costs is low.
2. the utility model can adopt the sheet material manufacturing thinner than existing beam body thickness under the situation that satisfies the requirement of step operation bearing safety, realizes that the step gross weight of same specification reduces greatly, and the power consumption in the time of can reducing the operation of terraced road is saved operating cost.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as shown in Figures 1 to 4, a kind of light-duty staircase tread crossbeam, comprise strip shape main body 1, the long limit of described main body 1 both sides inwardly vertically is bent to form first bearing surface 2 and second bearing surface 3 respectively, the long limit of described first bearing surface 2 outer ends outwards vertically bends and extends to form attachment face 4, the long limit of described second bearing surface 2 outer ends and a cross-sectional plane are that the long limit of Z-shaped flanging 5 outer ends joins, and the other two sides of described flanging 5 and main body 1 are positioned at the homonymy of the one side of the flanging 5 that above-mentioned and second bearing surface 2 join.
Described attachment face 4 is provided with some mounting holes, can be in order to be connected and fixed with stair step tread bottom side.
Described main body 1 vertical two ends are provided with the installation portion 6 towards plane, attachment face 4 place depression, and described installation portion 6 is provided with mounting hole, are connected and fixed in order to delimit with the safety of the step tread left and right sides.
The utility model is the Z-shaped flanging of bending upwards, and the effectively bend resistance of strengthened beam body, anti-twist intensity can the attenuate material thicknesses under the situation of bearing force equally and can reach same moment of torsion, moment of flexure requirement; Under the situation that satisfies the requirement of step operation bearing safety, can adopt the sheet material manufacturing thinner than existing beam body thickness, realize that the step gross weight of same specification reduces greatly.
