Abstract
The utility model provides a metal ladder crosspiece which comprises a semicircular tube and ribs evenly distributed on the surface of the semicircular tube, wherein the ribs are longitudinally distributed on the surface of the semicircular tube. The metal ladder crosspiece is strong in bearing performance, anti-skidding, good in safety performance and small in material consumption.
Description
Technical field
The utility model belongs to technical field of buildings, designs a kind of wire ladder crosspiece especially.
Background technology
The crosspiece of existing wire ladder is round tube or box section, and the foot-operated face of round tube is level and smooth, and box section stress is concentrated easy deformation, fractureed, and potential safety hazard is bigger.Therefore need a kind of ability to bear strong, anti-skidding, the crosspiece of the wire ladder of high safety.
The utility model content
To the problem that background technology exists, the utility model provides a kind of wire ladder crosspiece.
For solving the problems of the technologies described above, the utility model adopts following technical scheme.
A kind of wire ladder crosspiece comprises semicircular pipe and is evenly distributed on its surperficial rib.
Said rib vertically is distributed in the surface of semicircular pipe.
Compared with prior art, the utlity model has following advantage and beneficial effect:
1, the utility model does not adopt rib to be distributed in the surface of semicircular pipe, makes its ability to bear strong, and stress distribution is even, and is yielding, fracture, so safety is good.
2, the semicircular pipe and the rib of the utility model employing have been saved raw material.
Description of drawings
Fig. 1 is the sectional view of the utility model.
Fig. 2 is the elevation of the utility model.
Wherein, 1-semicircular pipe, 2-rib.
The specific embodiment
Below in conjunction with embodiment shown in the drawings the utility model is described further.
Shown in accompanying drawing, the utility model comprises semicircular pipe 1 and is evenly distributed on its surperficial rib 2; Rib 2 vertically is distributed in the surface of semicircular pipe 1.
During use, semi circular surface is partly upwards as foot-operated face.Facts have proved that under the situation consistent at material, that size is identical, the holding capacity of the utility model, non-deformability can improve 10%.
Claims (2)
1. a wire ladder crosspiece is characterized in that: comprise semicircular pipe and be evenly distributed on its surperficial rib.
2. a kind of wire ladder crosspiece according to claim 1, it is characterized in that: said rib vertically is distributed in the surface of semicircular pipe.
